The present invention implements the method and the method for the incoming call selection connection service for the mobile communication terminal which can determine the processing of the incoming call by the subscriber's choice (call connection, call rejection, call request after 10 minutes, confirmation of important call, etc.) The present invention relates to a computer-readable recording medium having recorded thereon a program.

As telephones become popular, they are used in various environments. In particular, with the development of mobile communication, many people use mobile phones and the popularization of wireless phones in the home makes it possible to make calls anytime, anywhere, not only in the house.

However, there may be times when you want to avoid incoming calls from people you do not want to receive (specifically), or you may not be able to make a phone call with the other party immediately (conferences, etc.). According to the principle, it is based on the receiver's choice.

Therefore, until now, various measures have been taken to prevent an arbitrary call, and in terms of personal convenience and privacy protection, a caller ID (CID) service is currently implemented, informing the caller's telephone number in advance and being absent. Leave the other's information to get rid of frustration. This service frees you from phone stress caused by incoming calls, and you can prevent phone stress by reading the phone number displayed on your device and not receiving it if you don't know or bother yourself. In addition, it is possible to make a call by calling the phone number displayed on the terminal later in a situation where a phone call with the other party cannot be made immediately.

However, such caller ID (CID) services do not necessarily provide a positive side. Through this service, a mobile phone rings in a subway, bus, or public place, but sometimes the caller's phone number is not reported and received, which causes inconvenience to the surrounding people. This is because the caller ID service is a passive call processing method that checks by caller ID display when a call is received and does not receive a number that it does not want until the call is transferred to missed call. In addition, if a call is automatically switched after a predetermined time in a situation (meeting, class, etc.) where a telephone call cannot be made immediately with the other party, the caller cannot know the current situation of the called party and is therefore frustrated.

In other words, the present Caller ID (CID) service is a passive method of receiving all incoming calls and automatically transferring the call after a predetermined time, and is not an active way of selectively determining the handling of the incoming call by the called party.

Accordingly, through such a caller ID (CID) service, an active caller who can determine the handling of an incoming call (call connection, call rejection, call request after 10 minutes, check whether an important call, etc.) is selected by the subscriber (recipient). A call processing method is urgently needed.

The present invention has been proposed to meet the above requirements, and is a mobile communication terminal for processing incoming calls (call connection, call rejection, call request after 10 minutes, confirmation of important phone call, etc.) by active selection of subscribers.

It is a service that can be served.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of an incoming call connection service system to which the present invention is applied, and shows a system configuration capable of determining processing of an incoming call by selection of a called subscriber using an intelligent network standard. This is an implementation of the 'incoming call selection connection service' with minimal modification of communication network components.

The destination terminal 16 is a mobile communication terminal such as a personal digital assistant (PDA), a handheld PC, a notebook, a cellular phone, or a personal communication service (PCS) phone, which the user can carry and carry out voice communication. Mobile station (MS) including next-generation mobile communication terminal such as IMT-2000 phone or CDMA-2000 phone, which uses forward channel when receiving calls and reverse channel when calling In particular, when the caller attempts to make a phone call (when calling), the calling terminal through a communication network (i.e., mobile communication network-mobile communication network, public telephone network (PSTN)-mobile communication network, LAN-mobile communication network, etc.) Voice call with (11) is possible. However, it is assumed here that the terminal is subscribed to the 'incoming call selection connection service'.

The calling terminal 11 may be a general PC or a wired or wireless telephone, a mobile communication terminal (MS), etc., and a voice call is made with the called terminal 16 through a mobile communication network, a public telephone network (PSTN), a wired or wireless LAN (LAN), and the like. . However, hereinafter, the description will be given mainly for the called party connected to the mobile communication network. Note that the following mobile communication network environment applies equally to the calling party connected to the mobile communication network.

In general, a mobile communication network includes a base station transceiver subsystem (BTS) (not shown), a base station controller (BSC) (not shown), and a mobile switching center (MSC) 13 ) And the like.

The base station (BTS) connects a terminating terminal (MS) 16 to a base station controller (BSC), a digital channel unit (DCU), a time / frequency control unit (TCU: Timing / Frequency Control Unit), It consists of a Radio Frequency Unit (RFU) and a Global Positioning System (GPS). The base station (BTS) performs a wired / wireless conversion function of communicating with the destination terminal (MS) 16 over the air and communicating with the base station controller (BSC) by wire.

The base station controller (BSC) connects a base station (BTS) to an exchange (MSC) 13 to coordinate the connection between the base stations (BTS), and signal processing for communication between the base station (BTS) and the exchange (MSC) 13. Perform the function.

On the other hand, the MSC 13 includes a Visitor Location Register (VLR) 13, a Home Location Register (HLR) 14, and a Service Controller (SCP) 15. It handles mobile subscriber call in connection. In addition, the exchange 13 connects to the base station controller BSC to perform call setup and release functions of the called terminal MS 16, and performs various functions related to call processing and additional services. However, when the originating exchange 12 is located in a public telephone network (PSTN), the call exchanger 12 performs a call setting and release function of the calling terminal 11 in association with the subscriber DB and performs various functions related to call processing and additional services. .

The visitor location register (VLR) 13 then provides subscriber information associated with the destination terminal (MS) 16 while the destination terminal (MS) 16 is in an area controlled by the visitor location register (VLR) 13. Is a database for temporarily storing the information of the destination terminal (MS) 16 and the subscriber whose location is registered in the area in charge of the user from the home location register (HLR) 14 and temporarily stored therein, and the exchange (MSC) ( It is mounted in 13).

The home location register (HLR) 14 is a database that is connected to the exchange (MSC) 13 and the service controller (SCP) 15 to manage various information of mobile subscribers. It performs a function such as registration of subscriber location by interworking, stores permanent information and location information of called terminal (MS) 16 and subscriber, and interacts with visitor location register (HLR) 13 to process call and It supports various functions related to additional services. In particular, the home location register (HLR) 14 stores the triggering information according to the service used by the subscriber.

The service controller (SCP) 15 is a device for service control in a mobile communication network, and a service using the service controller (SCP) 15 in an intelligent network is started using triggering.

For example, the 'incoming call selection service' of the present invention inputs a specific Unstructured Supplementary Service Data (USSD) code before the subscribers who have subscribed to the service perform other important tasks (such as attending a meeting, watching a movie, or a class). For example, you can activate the service by * 107 #). As another example, the service may be activated by changing the subscriber's selective information through the ARS.

The activation process of the 'incoming call selection service' will be described in more detail with reference to FIG. 2.

In this way, the call delivered to the terminal 16 of the subscriber (the called party) who does not activate the service is treated the same as the incoming call delivered to the general subscriber (the called party) (general call notification when the service is deactivated). Call processing in the inactive state will be described in more detail with reference to FIG. 9.

However, when the call is delivered to the called terminal 16 with the service activated, the incoming call is notified by a text message (SMS or USSD) regardless of the called method (ring tone, vibration, etc.) set in the called terminal 16. (Text call notification upon service activation) (see Figure 3 below).

That is, when the called terminal 16 confirms the incoming call according to the notification of the incoming call when the service is activated, the menu of the format that the called party can select is displayed on the called party's terminal 16 as shown in Table 1 below. Is displayed to wait for a response from the called party.

A menu of the form as shown in [Table 1] is sent out to the called terminal 16 using the USSD function and displayed. The menu is processed interactively with the caller by selecting a number using the called keypad.

At this time, the incoming call is appropriate according to the selection of the called subscriber.

If the called subscriber selects '① call connection', the caller connects the call between the caller and the called subscriber in the same manner as general incoming call processing (see FIG. 4 below).

On the other hand, when the called party selects '② call rejection', the caller sends out an appropriate announcement (for example, "I can't answer the phone because I'm busy on another job. I'm sorry.") And terminate the call. (See Figure 5 below).

On the other hand, if you select 'Request call after 10 minutes ③', the caller will be notified of the appropriate announcement (for example, "You can't answer the phone because you are busy. Please call again in 10 minutes.") The call is sent and the call is terminated (see FIG. 6 below).

On the other hand, if you select '④ Check if the call is important', you can send a caller (for example, "Is an urgent call?") To the caller to check if the call should be connected immediately (check whether the call is an emergency call). Determining and dealing with a call connection or interruption accordingly. At this time, the caller may notify the called subscriber whether the call is an important call by selecting a number using the keypad of the calling terminal, and the information is collected and processed by the DTMF collection function of the system (see FIG. 7 and the following). 8).

2 is a detailed flowchart illustrating a service activation process of an incoming call selection connection service method according to the present invention.

First, the originating terminal (which eventually becomes the terminating service subscriber terminal) 11 through the USSD service code (for example, "* 107 #", etc.) (see [Table 2] below) to the 'incoming call selection connection service' When requesting activation (Process USSD Request) 201, the home location register (HLR) 14 connects it to a service controller (SCP) 15 that processes the incoming call selection connection service (Process USSD Request). (202). That is, when the calling terminal (which eventually becomes the called service subscriber terminal) 11 inputs a USSD service code to request call selection activation, a Process USSD Request operation is transmitted to the corresponding service controller (SCP) 15, Requires activation of the 'Incoming Call Selection Service'.

Thereafter, the service controller (SCP) 15 checks the service subscription and the service code to change the activation flag of the service of the corresponding subscriber, and the result (that is, the call selection activation result) (see [Table 3 below]). ] Is sent to the home location register (HLR) 14 using USSD Notify (203).

Next, the home location register (HLR) 14 transmits the incoming call selection activation result through the USSD Notify message to the calling terminal (after all, the receiving service subscriber terminal) 11, for example, the incoming call during the conference. Informs that the mode has been changed to the selective connection mode (204).

Then, the calling terminal (which eventually becomes the called service subscriber terminal) 11 sends an incoming call selection activation result response message (USSD Notify ACK) for the USSD Notify message to the home location register (HLR) 14 (205). The home location register (HLR) 14 sends an incoming call selection activation result response message (USSD Notify ACK) to the service controller (SCP) 15 (206).

Finally, the service controller (SCP) 15 sends an incoming call selection activation request response message (Process USSR Request ACK) via the home location register (HLR) 14 (in the end, becomes an incoming service subscriber station). By sending to 11 (207, 208), the USSD transaction for service activation is terminated.

3 is a detailed flowchart illustrating an incoming call notification process in the incoming call selection connection service method according to the present invention.

First, when an arbitrary caller sends a call to an incoming call selection connection service subscriber and a call processing request arrives at the destination exchange (MSC) 13 (301, 302), the destination exchange (MSC) 13 informs that the incoming service is a protocol. An intelligent network processing request is made to the service controller (SCP) 15 by (T-CSI) (Initial DP) 303.

Subsequently, the service controller (SCP) 15 generates an information collection request message (SendImsi) that can obtain the number of the called subscriber that the network knows in order to know the called subscriber's number (msisdn). In step 304, the home location register (HLR) 14 receives the information collection request response message SendImsi Ack for the SendImsi message and obtains the called party's number (called number) (305).

Next, the service controller (SCP) 15 confirms that the incoming call selection connection service is a service key (KEY) value, and sends a USSD Request operation to the home location register (HLR) 14 to indicate the contents of the call to the called party. Inform (306). On the other hand, the home location register (HLR) 14 sends an incoming call notification message (USSD Request) to the called terminal 16 to inform that the call is received (the menu shown in Table 1 above to the called terminal 16). 307, a response message (USSD Request ask) from the called terminal 16 (i.e., the subscriber's choice, "① call connection, ② call rejection, ③ call request after 10 minutes, ④ whether the call is important) Acknowledgment, etc.) (308), and informs the service controller (SCP) 15 (309).

A service controller that receives a USSD Request ask message from the home location register (HLR) 14 (subscriber's choice, i.e. call connection, rejection, call request after 10 minutes, check whether it is an important call, etc.) SCP) (15) may terminate the call depending on the scenario selected by the called party, or may send an announcement not answering the call, or send a prompt asking if it is urgent. This will be described in more detail with reference to FIGS. 4 to 8 below.

4 is a detailed flowchart illustrating a call processing process at the time of call connection selection in an incoming call selection connection service method according to the present invention.

First, when an arbitrary caller sends a call to an incoming call selection connection service subscriber and a call processing request arrives at the destination exchange (MSC) 13 (401, 402), the destination exchange (MSC) 13 informs that the incoming service is a protocol. An intelligent network processing request is made to the service controller (SCP) 15 by (T-CSI) (Initial DP) 403.

Subsequently, the service controller (SCP) 15 generates an information collection request message (SendImsi) that can obtain the number of the called subscriber that the network knows in order to know the called subscriber's number (msisdn). 404 receives the information collection request response message SendImsi Ack for the SendImsi message from the home location register (HLR) 14, and obtains the recipient's number (called number) (405).

Next, the service controller (SCP) 15 confirms that the incoming call selection connection service is a service key (KEY) value, and sends a USSD Request operation to the home location register (HLR) 14 to indicate the contents of the call to the called party. (406). On the other hand, the home location register (HLR) 14 sends an incoming call notification message (USSD Request) to the called terminal 16 to inform that the call is received (the menu shown in Table 1 above to the called terminal 16). 407, and receives a response message (USSD Request ask) (that is, assuming that the selection of the subscriber selected "① call connection") from the destination terminal 16 (408), Notified to the service controller (SCP) 15 (409).

As such, steps "401" to "409" follow the procedure of FIG. However, since the subscriber selects the "① call connection", the service controller (SCP) 15 instructs the destination exchange 13 to carry on the call in the Continue message (410), and sends a TAP END message. The process for the call is terminated (411).

5 is a detailed flowchart illustrating a call processing process at the time of call rejection selection in an incoming call selection connection service method according to the present invention.

First, when an arbitrary caller sends a call to an incoming call selection connection service subscriber and a call processing request arrives at the destination exchange (MSC) 13 (501, 502), the destination exchange (MSC) 13 informs that the incoming service is a protocol. An intelligent network processing request is made to the service controller (SCP) 15 by (T-CSI) (Initial DP) 503.

Subsequently, the service controller (SCP) 15 generates an information collection request message (SendImsi) that can obtain the number of the called subscriber that the network knows in order to know the called subscriber's number (msisdn). In step 504, the home location register (HLR) 14 receives the information collection request response message SendImsi Ack for the SendImsi message and obtains the called party's number (called number) (505).

Next, the service controller (SCP) 15 confirms that the incoming call selection connection service is a service key (KEY) value, and sends a USSD Request operation to the home location register (HLR) 14 to indicate the contents of the call to the called party. (506). On the other hand, the home location register (HLR) 14 sends an incoming call notification message (USSD Request) to the called terminal 16 to inform that the call is received (the menu shown in Table 1 above to the called terminal 16). 507), receiving a response message (USSD Request ask) (i.e., assuming that the subscriber's selection selects ② call rejection) from the destination terminal 16 (508), and service Notified to the controller (SCP) 15 (509). Then, the service controller (SCP) 15 delivers a comment on the call rejection according to the scenario selected by the subscriber (when "2) call rejection".

As such, steps "501" to "509" follow the procedure of FIG. However, since the subscriber selects the "② rejection of call", the subscriber requests the connection with the calling terminal 11 to the calling exchange 12 using an EstablishTemporaryConnection (ETC) message (510). On the other hand, the originating exchange 12 establishes a connection with the originating terminal 11 according to the control command of the service controller (SCP) 15 (SetUp) 511.

Then, after the connection with the originating exchange 12 is established, the originating terminal 11 transmits an AssistRequest Instruction (ARI) message to the service controller (SCP) 15 to inform the control command waiting state (512). In response to this, the service controller (SCP) 15 transmits an announcement to the calling terminal 11 that the called subscriber cannot receive a call (513), and then the SRR (Specialized) for ending the announcement from the calling terminal 11. Resource Report) message is received (514), the connection release message (DFC) is sent to the originating terminal 11 to release the connection (515), the call termination message (Release Call) to the destination exchange 13 to send a call End (516).

FIG. 6 is a detailed flowchart illustrating a call processing process when a call connection is selected after 10 minutes in an incoming call selection connection service method according to the present invention.

First, when an arbitrary caller sends a call to an incoming call selection connection service subscriber and a call processing request arrives at the destination exchange (MSC) 13 (601, 602), the destination exchange (MSC) 13 informs that the incoming service is a protocol. An intelligent network processing request is made to the service controller (SCP) 15 by (T-CSI) (Initial DP) 603.

Subsequently, the service controller (SCP) 15 generates an information collection request message (SendImsi) that can obtain the number of the called subscriber that the network knows in order to know the called subscriber's number (msisdn). In step 604, the receiver receives the information collection request response message SendImsi Ack for the SendImsi message from the home location register (HLR) 14 to obtain the called party's number (called number) (605).

Next, the service controller (SCP) 15 confirms that the incoming call selection connection service is a service key (KEY) value, and sends a USSD Request operation to the home location register (HLR) 14 to indicate the contents of the call to the called party. (606). On the other hand, the home location register (HLR) 14 sends an incoming call notification message (USSD Request) to the called terminal 16 to inform that the call is received (the menu shown in Table 1 above to the called terminal 16). 607), receiving a response message (USSD Request ask) from the destination terminal 16 (i.e., assuming that the subscriber's selection selects "call request after 10 minutes ③") (608), This is informed to the service controller (SCP) 15 (609). Then, the service controller (SCP) 15 delivers the message "Please call back after 10 minutes" according to the scenario selected by the subscriber ("3. 10 minutes call request").

Therefore, since the subscriber selects “Request call after 10 minutes ③,” it requests a connection with the calling terminal 11 to the calling exchange 12 using an EstablishTemporaryConnection (ETC) message (610). On the other hand, the originating exchange 12 establishes a connection with the originating terminal 11 according to the control command of the service controller (SCP) 15 (SetUp) 611.

Then, after the connection with the originating exchange 12 is established, the originating terminal 11 transmits an AssistRequest Instruction (ARI) message to the service controller (SCP) 15 to notify that the control command is waiting (612). In response to this, the service controller (SCP) 15 transmits an announcement to the calling terminal 11 ("Call me back in 10 minutes") to call back 10 minutes since the called party cannot receive a call. 613, when receiving a Specialized Resource Report (SRR) message for the termination of the announcement from the calling terminal 11 (614), by sending a disconnection message (DFC) to the calling terminal 11 to release the connection (615), A call termination message (Release Call) is sent to the destination exchange 13 to terminate the call (616).

7 is a detailed flowchart illustrating a call termination process after confirming that the call is an important call in the incoming call selection connection service method according to the present invention.

First, when an arbitrary caller sends a call to an incoming call selection connection service subscriber and a call processing request is received by the destination exchange (MSC) 13 (701, 702), the destination exchange (MSC) 13 informs that the incoming service is a protocol. An intelligent network processing request is made to the service controller (SCP) 15 by (T-CSI) (Initial DP) 703.

Subsequently, the service controller (SCP) 15 generates an information collection request message (SendImsi) that can obtain the number of the called subscriber that the network knows in order to know the called subscriber's number (msisdn). 704 receives the information collection request response message SendImsi Ack for the SendImsi message from the home location register (HLR) 14, and obtains the recipient's number (called number) (705).

Next, the service controller (SCP) 15 confirms that the incoming call selection connection service is a service key (KEY) value, and sends a USSD Request operation to the home location register (HLR) 14 to indicate the contents of the call to the called party. (706). On the other hand, the home location register (HLR) 14 sends an incoming call notification message (USSD Request) to the called terminal 16 to inform that the call is received (the menu shown in Table 1 above to the called terminal 16). 707 receives a USSD Request ask (i.e., suppose the subscriber's choice is "4) that the user's choice is important" from the called terminal 16 (708). This is informed to the service controller (SCP) 15 (709). Then, the service controller (SCP) 15 performs a scenario of inquiring that the call is important according to the scenario selected by the subscriber (when "4. confirm whether the call is important").

Accordingly, since the subscriber selects the "check whether the telephone is an important call", the subscriber requests the connection with the calling terminal 11 to the calling exchange 12 using an EstablishTemporaryConnection (ETC) message (710). On the other hand, the originating exchange 12 establishes a connection with the originating terminal 11 according to the control command of the service controller (SCP) 15 (SetUp) 711.

Then, after the connection with the originating exchange 12 is established, the originating terminal 11 transmits an AssistRequest Instruction (ARI) message to the service controller (SCP) 15 to notify that the control command is waiting (712).

Subsequently, the service controller (SCP) 15 transmits an announcement broadcast and a user input collection request message (PCUI: PromptAndCollectUserInformation) to the calling terminal 11 in order to send an announcement requesting that the call is important and collect user input. 713, collects a result of whether it is an important call from the calling terminal 11 (PCCI ASK) 714.

For example, if the called party selects "Make sure it is an important call," the service controller (SCP) 15 asks the calling terminal 11 that the called party is an important call. If not, please press 2 times. ", And collects the confirmation result (1 or 2) from the destination terminal (11).

Subsequently, the service controller (SCP) 15 notifies the destination terminal 16 via the home location register (HLR) 14 of the confirmation result (the result of whether it is an important call) (USSD Request) (715,716), and the incoming call. A response message (USSD Request ASK) is received from the terminal 16 via the home location register (HLR) 14 (717, 718).

If the caller enters an insignificant call (i.e., selects 2), the service controller (SCP) 15 may not be able to talk to the called party and will be contacted (or may be a voice message). In order to send the announcement to leave and collect the user input to send the announcement broadcast and user input collection request message (PCUI) to the calling terminal 11 (719), the number to be contacted from the calling terminal 11 (or Voice message) (PCCI ASK) 720.

For example, if the called party selects 2 (non-important phone), the service controller (SCP) 15 sends a message to the calling terminal 11 such as "Leave a phone number (callback number) to be contacted". By sending, collect the phone number to be contacted from the destination terminal (11).

Next, the service controller (SCP) 15 releases the connection by sending a disconnection message (DFC) to the calling terminal 11 (721), the home location register (HLR) 14, the phone number left by the caller, etc. Notification to the destination terminal 16 via USSD Notify (722, 723), and a response message (USSD Notify ASK) from the destination terminal 16 via the home location register (HLR) 14 (724,725). In step 726, the call termination message (Release Call) is sent to the destination exchange 13 to terminate the call.

8 is a detailed flowchart illustrating a call connection process after confirming that the call is an important call among the incoming call selection connection service method according to the present invention.

First, when an arbitrary caller sends a call to an incoming call selection connection service subscriber and a call processing request arrives at the destination exchange (MSC) 13 (801,802), the destination exchange (MSC) 13 informs that the incoming service is a protocol. An intelligent network processing request is made to the service controller (SCP) 15 by (T-CSI) (Initial DP) 803.

Next, the service controller (SCP) 15 confirms that the incoming call selection connection service is a service key (KEY) value, and sends a USSD Request operation to the home location register (HLR) 14 to indicate the contents of the call to the called party. (806). On the other hand, the home location register (HLR) 14 sends an incoming call notification message (USSD Request) to the called terminal 16 to inform that the call is received (the menu shown in Table 1 above to the called terminal 16). Indicated) (807), and receives a response message (USSD Request ask) (i.e., suppose the subscriber's choice is "4) whether it is an important call" from the called terminal 16 (808) This is informed to the service controller (SCP) 15 (809). Then, the service controller (SCP) 15 performs a scenario of inquiring that the call is important according to the scenario selected by the subscriber (when "4. confirm whether the call is important").

Accordingly, since the subscriber selects the "check whether the telephone is an important call", the subscriber requests the connection with the calling terminal 11 to the calling exchange 12 using an EstablishTemporaryConnection (ETC) message (810). On the other hand, the originating exchange 12 establishes a connection with the originating terminal 11 according to the control command of the service controller (SCP) 15 (SetUp) 811.

Then, after the connection with the originating exchange 12 is established, the originating terminal 11 transmits an AssistRequest Instruction (ARI) message to the service controller (SCP) 15 to notify that the control command is waiting (812).

Subsequently, the service controller (SCP) 15 transmits an announcement broadcast and a user input collection request message (PCUI: PromptAndCollectUserInformation) to the calling terminal 11 in order to send an announcement requesting that the call is important and collect user input. 813, collects a result of whether it is an important call from the calling terminal 11 (PCCI ASK) 814. FIG.

For example, if the called party selects "Make sure it is an important call," the service controller (SCP) 15 asks the calling terminal 11 that the called party is an important call. If not, please press 2 times. ", And collects the confirmation result (1 or 2) from the destination terminal (11).

Subsequently, the service controller (SCP) 15 notifies the destination terminal 16 via the home location register (HLR) 14 of the confirmation result (the result of whether it is an important call) (USSD Request) (815, 816), and the incoming call. A response message (USSD Request ASK) is received from the terminal 16 via the home location register (HLR) 14 (817, 818).

If the caller enters an important call (i.e., selects 1), a call connection progress message (Continue) is sent to the destination exchange 13 (Continue) (819) and the destination terminal (11, 16). A call is established between the terminals, and the corresponding log (Dial Log) is terminated by sending a TCAP END message to the destination exchange 13 (820).
