Description
Technical field
The present invention relates to the communications field, particularly, a kind of measuring quality of location service that relates in the wireless communication field is accurately determined method and apparatus, has especially related to the method and apparatus of the measuring quality of location service that better obtains to satisfy location information request in a kind of WCDMA.
Background technology
Mobile location service in the Radio Network System more and more is subjected to paying close attention to widely.
The main application of mobile location service includes: the emergency calling position service that is used for user security; Follow the tracks of the location of relevant criminal activity; Individual's positioning service (for example inquiry of service industry such as traffic, lodging information); Intelligent transportation transportation location; The design of Radio Network System and resource management; Be used for the charging (determining the communication cost of some position according to calling rate) of Radio Network System.
Mobile positioning technique includes: based on the location of sub-district covering, strengthen observed time difference (EOTD, Enhanced Observation Time Difference) location, the observable time of advent poor (OTDOA, Observed Time Difference Of Arrival) location, the time of advent (TOA, Time Of Arrival) location, arrive angle (AOA, Arrivalof Angle) location, advanced forward link triangle (AFLT, Advanced Forward LinkTrilateration) location, strengthen forward link triangle (EFLT, Enhanced ForwardLink Trilateration) location, uplink time-difference of arrival (UTDOA, UpLinkTime Difference of Arrival) the multiple technologies modes such as global positioning system (AGPS, Assisted Global Positioning System) location of location and network assistance.
Divide if satisfy the situation of service quality according to positioning result, can be divided into the three major types location technology again:
1. low precision location technology, the location technology that covers based on the sub-district for example, the current position that is in the sub-district of good location accuracy and sub-district covering and the user that is positioned is relevant usually, but the response time is fast.
2. middle precision location technology, location technologies such as EOTD, OTDOA, TOA, AOA, AFLT, EFLT, UTDOA for example, good location accuracy and wireless environment etc. are relevant usually.Response time is between the response time of low precision location technology and hi-Fix technology.
3. hi-Fix technology, for example AGPS comprises all kinds of satellite systems that GPS (Global Position System) (GNSS, Global Navigation Satellite Systems) comprises etc.Response time is the slowest, even can reach tens of seconds.
The use of different location technologies is relevant with the service quality of the user capability that is positioned, mobile network's stationkeeping ability and residing environment of the user that is positioned and Location Request.The location response time of different location technologies is also different with positioning accuracy simultaneously.So need be in conjunction with the location quality of service needed location technology in a certain position fixing process of coming together specifically to select.
The service quality of positioning service (QOS, Quality Of Service) is embodied by two class indexs: positioning accuracy (Accuracy), response time (Response time).
Each class standard of existing positioning service and realization have defined three classes for the response time of service quality: no time delay (No Delay), low time delay (Low Delay), time delay tolerable (Delay Tolerance).Description for this three class definition is:
1. " no time delay ": location-server offers the location estimation value that its currently known any one of Location Request client has timestamp.If can not provide any one estimated position on the current location-server, then return a failure Indication message to the Location Request client, alternatively, can then initiate a position fixing process, obtain location estimation so that follow-up position fixing process uses.
2. " low time delay ": between the positioning accuracy of response time of application request and application request, pay the utmost attention to the response time requirement that satisfies application request.Provide as far as possible a low precision fast response positioning result rather than, but the positioning result of more accurate slow-response.
3. " time delay tolerable ": between the positioning accuracy of response time of application request and application request, pay the utmost attention to the positioning accuracy request that satisfies application request.Be necessary that location-server can postpone to provide positioning result to provide when having satisfied the required precision of application request to the location requesting client again.
Under the prerequisite of indeterminate delay requirement, select also can determine localization method for localization method, to obtain accurately to satisfy the location positioning result of service quality according to the network element analysis that the type of service of location service is selected by left localization method.
Yet for low time delay type of second class and/or the 3rd class time delay tolerable type, the location-server of receiving position request can not determine that the time delay of concrete localization process response time how long is to belong to low time delay category and/or time delay tolerable category actually.For example, usually, the response time of middle precision location technology can reach about 3 seconds, and the also possible response time is longer under the still specific wireless environment; In some cases, the location response time of hi-Fix technology also can finish in 3 seconds, but also had tens of seconds response time just to finish the possibility of location, even located failure after tens of seconds and can not obtain positioning result.
