Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a first embodiment of a method for measuring secondary mode information of GSM according to the present invention, where the scheme of this embodiment is used in a network scenario where multiple communication systems coexist, and when a UE needs to switch to another network when a signal of a primary mode network is unstable, detection time is shortened when detecting the secondary mode information of GSM, an execution main body of this embodiment is the UE, and as shown in fig. 1, specific implementation steps are as follows:
s101: when detecting an idle time slot GAP of the master mode network, judging whether the GAP is used for GSM measurement according to the pre-acquired scheduling parameters.
In this embodiment, when the signal of the master mode network is weak, the UE detects the usage of the GAP in an idle timeslot (a timeslot unused by the master mode network) GAP periodically started by the master mode network on the premise of keeping the UE communication uninterrupted, and determines whether the GAP is used for measuring other inter-frequency and inter-system signals of the master mode network or for measuring GSM signals, so as to perform subsequent processing.
Generally, the scheduling parameters include the GAP period of the master mode network and the number of pilot frequency points other than GSM. The UE may directly receive the scheduling parameter from the network side, or may send an acquisition request to the network to acquire the scheduling parameter.
S102: if the GAP is used for GSM measurement, carrying out polling scheduling detection on the BSIC verification of the base station identification code and the RSSI measurement of the received signal strength by taking the GAP as a unit according to a pre-configured detection mode to acquire the slave mode information of the GSM; the detection mode comprises the BSIC verification and the RSSI measurement scheduling mode.
In this embodiment, if it is detected that the GAP is used for performing other inter-frequency and inter-system measurements, the measurement is performed according to the existing measurement method, which may refer to the prior art and is not described herein again.
If the GAP is detected to be used for GSM measurement, GSM detection is carried out according to a configured detection mode, the GSM detection comprises BSIC verification and Received Signal Strength (RSSI) measurement, polling detection is carried out in each GAP period according to the BSIC verification and RSSI measurement specified in the detection mode in the process of carrying out GSM detection until the GSM is obtained as slave mode information of the slave mode network.
In the method for measuring slave mode information of GSM provided in this embodiment, by setting a detection mode, BSIC verification and RSSI measurement are performed in a predetermined detection mode in a time slot for performing GSM measurement, and an idle time slot GAP of a master mode network is reasonably allocated, so that the maximum time for BSIC verification failure is shortened, and thus the time for acquiring the slave mode information of GSM is effectively shortened.
Fig. 2 is a flowchart of a second embodiment of the method for measuring GSM slave mode information according to the present invention, as shown in fig. 2, based on the first embodiment, the specific steps of the present embodiment are as follows:
s201: when detecting an idle time slot GAP of the master mode network, judging whether the GAP is used for GSM measurement according to the pre-acquired scheduling parameters.
In this embodiment, the specific implementation manner is the same as that in the first embodiment, and after it is determined that the GAP is used for GSM measurement, the specific manner for implementing GSM measurement is executed according to steps S202 and S203.
S202: if the GAP is detected to be used for RSSI measurement according to the detection mode, RSSI measurement is carried out in the GAP to obtain the signal energy of the GSM; and if the GAP is detected to be used for BSIC verification according to the detection mode, carrying out BSIC verification in the GAP to obtain the BSIC of the cell of the GSM.
In this embodiment, the detection method includes the following settings: continuously carrying out two times of BSIC verification and then carrying out RSSI measurement; alternatively, BSIC verification and RSSI measurement are performed alternately. Since the BSIC verification itself needs more time, in the process of allocating BSIC verification and RSSI measurement, more idle timeslots need to be allocated for BSIC verification so as to acquire the BSIC of the corresponding cell, thereby completing BSIC verification. The detection method is not limited to the above two methods, and may be adjusted according to specific situations, as long as it is ensured that the BSIC verification GAP is more than the GAP measured by RSSI.
Specifically, after the UE detects the GAP for GSM test, it needs to further detect whether the GAP is used for RSSI measurement or BSIC verification until then according to the above-specified detection method,
and if the BSIC verification is detected, carrying out BSIC verification processing, wherein the BSIC verification comprises the following steps: the Frequency correction Burst (FB search) is periodically transmitted in fixed frames and fixed time slots at the broadcast Frequency of the GSM system. The method is mainly used for time synchronization and frequency synchronization of the UE, and the position of the SB can be estimated only when the FB search is to obtain the synchronization information of the broadcast frequency point, so as to carry out SB verification; synchronous Burst (SB) verification, and periodic transmission is carried out on fixed frames and fixed time slots on the broadcast frequency points of the GSM system. Each time a frame immediately following the FB is transmitted. The method is mainly used for accurate time synchronization of the UE, the SB carries BSIC information of the cell, and the UE demodulates and decodes the SB to obtain the BSIC of the cell, so that the BSIC verification is completed.
And if the RSSI measurement is detected, the RSSI measurement is carried out, and the signal energy of the received GSM signal is obtained.
S203: repeating the step S202 until the slave mode information of the GSM is obtained when the next GAP for GSM measurement is needed; wherein the GSM slave mode information comprises: signal energy level of GSM and cell BSIC code of GSM.
In this embodiment, if the RSSI measurement or BSIC verification is completed in S202 at the GAP, the next GAP is waited to arrive, and the step of S202 is repeated when it is determined that the measurement is for the GSM test, as in S201, and the measurement process is continued according to the specified RSSI measurement and BSIC verification scheduling mode, and after each GAP cycle is completed, the UE reports the detected information in real time.
And repeating S202 and S203 in a plurality of GAP periods until the slave mode information of the GSM is acquired.
S204: and sending the slave mode information of the GSM to the master mode network equipment so that the master mode network equipment completes the switching between the master mode network and the GSM slave mode network according to the slave mode information of the GSM.
In this embodiment, the UE acquires the slave mode information of the GSM in order to complete network handover, and therefore after acquiring the slave mode information of the GSM, the slave mode information of the GSM is reported to the master mode network device in real time, so that the network device of the master mode completes handover from the master mode network to another network in combination with the slave mode information of various networks.
Specifically, the master mode network device may complete the switching between the master mode network and the GSM slave mode network according to the GSM slave mode information.
In the method for measuring the slave mode information of the GSM provided in this embodiment, the detection mode is set, and two consecutive times of BSIC verification are set in the detection mode, and then RSSI measurement is performed; or, alternately performing BSIC verification and RSSI measurement, performing BSIC verification and RSSI measurement according to a preset detection mode in a time slot for performing GSM measurement, reasonably allocating an idle time slot GAP of the master mode network, and shortening the longest time of BSIC verification failure, thereby effectively shortening the time for acquiring the slave mode information of the GSM, so that the master mode network equipment can rapidly complete network switching under the condition that the UE does not stop communication.
With reference to the solutions of the first embodiment and the second embodiment, the following description will be made specifically for an example, to describe a measurement scheme of the slave mode information of GSM in the present invention, where in this example, the master mode network is LTE, and the following procedure is that the UE measures the slave mode information of GSM in LTE, specifically:
fig. 3 is a schematic diagram of an example scheduling scheme of a method for measuring secondary mode information of GSM according to the present invention, as shown in fig. 3, a square wave represents an operating state of a UE in a primary mode network LTE, and a raised portion represents an operating time of an LTE primary mode; the recessed part represents the idle time slot GAP of LTE, which is used for inter-frequency and inter-system measurement. In this example, the period of the GAP is 40ms or 80ms, which is specified by the network side. Each GAP duration is 6 ms. GSM and other inter-frequency systems take turns using this GAP. The RSSI measurements and BSIC verification are scheduled in a 1:2 or 1:1 ratio in turn to GSM.
As shown in fig. 3, it shows that when GAP is detected for GSM test at first, BSIC verification is performed, next time GAP is detected for GSM test, BSIC verification is still performed, next time GAP is detected for GSM test, RSSI measurement is performed again, and scheduling processing of RSSI measurement and BSIC verification is performed according to a ratio of 1: 2.
The RSSI measurements and BSIC verification are processed in a 1:1 manner similar to that described above.
Fig. 4 is a schematic diagram of an example scheduling flow of the method for measuring the slave mode information of GSM according to the present invention, and as shown in fig. 4, the specific process for detecting the slave mode information of GSM in LTE includes:
s301: the UE acquires scheduling parameters. The specific UE may receive the required scheduling parameters from the network side of LTE, for example, the period of GAP is 40ms, and the number of frequency points other than GSM is determined in the following manner.
S302: waiting for the next GAP to arrive. In the process that the GAP does not arrive, the UE still carries out normal communication in the LTE network.
S303: is the GAP determined to be used for GSM measurements? When the UE detects that a GAP comes, the UE determines whether to change the GAP for GSM measurement according to the acquired scheduling parameters, and if so, executes step S305; if not for GSM measurement, step S304 is performed.
S304: and carrying out other inter-frequency and inter-system measurement of LTE. If the GAP is not used for GSM measurement, the measurement of other different frequency and different systems of the LTE is carried out within the range of the GAP, the information of other network systems is obtained, and the information is reported to the LTE network side.
S305: is the GAP determined to be used for RSSI measurement according to a preset detection mode? If the GAP is detected to be used for the GSM measurement, further judging whether the GAP is used for the RSSI measurement according to a preset detection mode, and if the GAP is used for the RSSI measurement, executing S306; if not for RSSI measurement, S307 is performed.
S306: RSSI measurements for GSM measurements are made. Namely, RSSI measurement is performed in the GAP to obtain the signal energy of GSM, and then the next GAP is waited to continue the processing according to the flow in fig. 4.
S307: BSIC verification of GSM measurements was performed. Namely, BSIC verification is carried out in the GAP to obtain the BSIC of the cell of the GSM.
Specifically, BSIC verification includes FB search and SB verification. The FB search is to obtain the synchronous information of the broadcast frequency point, so that the position of the SB can be estimated, and then the SB verification is carried out. The scheme mainly discusses the longest time required by FB search in BSIC verification. This maximum time will behave differently under different scheduling regimes. The patent aims to find an optimal scheduling mode, namely allocating more GAPs for BSIC verification, and enabling the maximum theoretical time of FB search to be the shortest.
The following provides a table comparing the longest times obtained for the prior art test protocol to the test protocol of the present invention:
as shown in the above table, Number of carriers other than GSM: the number of other different frequency points except for GSM. 40ms gap configuration column: the maximum time for BSIC verification given by the protocol is 40ms for the GAP period. Column 80msgap configuration: the maximum BSIC verification time given by the protocol is 80ms for the GAP period. RSSI: BSIC column: the distribution mode of GAP for RSSI measurement and BSIC verification given in the invention, Simulation (available GAPPeriods ms): is the longest time for BSIC verification given by the scheme of the present invention.
Fig. 5a is a comparison graph of testing time with a GAP period of 40ms for an example of a measurement method of GSM slave mode information of the present invention, fig. 5b is a comparison graph of testing time with a GAP period of 80ms for an example of a measurement method of GSM slave mode information of the present invention, and in fig. 5a and 5b, the protocol requirement/2 is because the word time in the protocol includes two parts of time of FB search and SB verification. We here only compare the time of the FB search, corresponding to divide by 2 to show fairness. By combining the above table with fig. 5a and fig. 5b, it can be obtained that the idle time slot GAP of the master mode network is allocated according to a reasonable allocation manner, and GSM measurement is performed, so that the longest time required by BSIC verification can be effectively shortened, and the time for testing the slave mode information of GSM by the master mode can be shortened.
