At step 718 place, method is updated the equipment information database with the not success of reflection request condition.Method can also generate the control signal of setting up the daily record that makes mistakes.The equipment information table and the daily record that makes mistakes can one after the other be used to generate repairing and/or be that the MS that receives determines optimal operational parameters.Method also proceeds to step 720.At step 720 place, the request processing of positioning service is ended by the method for Fig. 7.
As mentioned above, manufacturing and the model for all MS equipment do not have sufficient performance data to use.EIP (in location-server 410) such as the EIP in Fig. 4 416 can keep performance database, and this database is mapped to various device with the device performance data of communication session, such as MS 440.
Fig. 8 illustrates the example performance database of form 800 forms, and described form can be kept by EIP.Database can be used for various MS device fabrications and model is collected performance data.Form can be stored in the memory easily, such as memory 414 (Fig. 4).Form 800 comprises following field: field 802 is used to store mobile subscriber identity information, such as international mobile subscriber identity (IMSI) in GSM/GPRS or the Electronic Serial Number (ESN) in the WCDMA communication system; Field 806 is used for the memory device manufacturer identifier; Field 808 is used for the memory model identifier; Field 810 is used to store talk time; Field 812 is used to positioning service to identify specific request; Field 814 is used for the code that storaging mark provides the best practice of positioning service; Field 816 is used for the memory error code; Field 818 is used to store first quality of service parameters, estimates such as the accuracy that the location is determined; And field 820 is used to store second quality of service parameters, such as preparing the time that location estimation needs.Can add added field to form 800.The not all field that illustrates all needs to be included in the form 800.In addition, system may use other database schemes.
Fig. 9 is the flow graph of explanation one method, and this method is collected performance data for the MS equipment that will be provided to positioning service.In beginning step 900, method receives will offering the request for location services of MS equipment, and proceeds to step 902.
In step 902, method is updated in the information in the equipment information database, such as the database that illustrates in Fig. 8, and the equipment identification information that receives with request with reflection, and proceed to step 904.Upgrade behavior database and can comprise the behavior that for example abandons outdated information.For example, in many systems, only to match with an IMSI or ESN, vice versa at every turn for IMEI.Therefore, if this kind system receives the request with IMSI or ESN pairing with IMEI, before the catalogue of IMEI and different IMS I or ESN pairing and the previous catalogue that IMSI or ESN and different I MEI are matched can be updated or delete.
At step 904 place, method is determined MS whether in the test tabulation, so that determine will be to its MS that positioning service is provided expected performance data whether.For example, manufacturing and the model that does not receive the MS equipment of complete standard performance test preferably needs performance data.If the answer at step 904 place is that then method does not proceed to step 950.If the answer of step 904 is that then method does not proceed to step 950.At step 950 place, method proceeds to the request (see figure 7) of processing to positioning service, and one after the other proceeds to aborting step 999.In step 906, method determines whether manufacturer and the model for the MS that positioning service is provided to it has list item in performance data table (form 800 that for example illustrates in Fig. 8).If in the answer at step 906 place for being that then method proceeds to step 908.If the answer at step 906 place is that then method does not proceed to step 922.
At step 908 place, method is determined whether known additional information and/or optimal operational parameters for the MS that positioning service is provided to it from performance data table.If the answer at step 908 place is for being that then method proceeds to step 910.If the answer at step 908 place is that then method does not proceed to step 920.At step 910 place, method generates control signal, and it is realized known additional information and/or optimal operational parameters and proceeds to step 922.At step 920 place, method generates control signal, and this signal system that makes when responding request for location services uses the default action parameter and proceeds to step step 922.
At step 922 place, the method continuation is handled the request (see figure 7) of positioning service and is proceeded to step 924.In step 924, method is from providing the MS request response of positioning service to it.Technical staff in the wireless communication field can recognize under certain test condition can omit step 924.For example, can provide response automatically.Method proceeds to step 926.At step 926 place, method receives response message and proceeds to step 928 from the MS that positioning service is provided to it.In step 928, the method assessment receives the MS performance of positioning service and proceeds to step 930.In step 930, method is the new capability form more, such as the performance form 800 of Fig. 8, with the reflection MS performance and proceed to step 999.A technical staff in the field can recognize that performance data can comprise actual performance values.Perhaps, performance data can comprise and indicates the data that whether meet desired value.
The request that the positioning service that is associated with MS is provided is not needed to originate from the MS that is associated.For example, position that MS may ask the 2nd MS.Perhaps, MS may be because other reasons be connected to communication system, and such as call of connection, and communication system can identification place MS be the type of expectation positioning service performance data.Therefore, communication system can be MS request positioning service automatically.
Technical staff in the radio communication can recognize that the steps of explanation in Fig. 6,7 and 9 do not need by illustrated in specific sequences, and some steps can be omitted, and maybe can carry out additional step and does not depart from principle of the present invention.
The example implementation of GSM
The mandatory features of GSM LCS and function are recorded in reference 3GPP TS 43.059 documents that comprise.Yet, exist one to consider that promptly existing MS can not accurately and fully be tested all forced characteristic/functions.Under GPS and assistant GPS (A-GPS) method situation, it is not standardized that MS meets test fully especially.Therefore, when one " is unlocked " in network without test characteristic or function, may have some risks, promptly the features/functionality of some MS (or features/functionality combination) is not worked.Some solutions to this kind problem in the mobile network system comprise: the network patch (if possible) of expense costliness even more expensive mobile update or disable function can obtain existing MS filling apparatus up to it and divide support.
In current gsm system, IMEI has been used to the incoherent defective of correcting encoder mistake and other and LCS.MSC obtains the IMEI that target moves by the standard signaling between MS and MSC.Yet current method can not be used for LCS, because IMEI determines that for the location network entity is unavailable, described entity may be mobile device or location-server.Present invention principle (as mentioned above) has advantageously overcome the restriction of prior art solution.On the one hand, IMEI information can be carried to MSC from GMLC to the request for location services of MSC.MSC can send complete IMEI message then or simply MS manufacturer and model information be sent to location-server and/or EIP.The element that this information can be used as in the standard location request message sends, and maybe can use radio access network to send by the priority message between MSC and location-server.If the GSM network can not use standard or priority message to provide MS identity information to location-server, then data form can maintain in location-server and/or EIP and/or the MS, as mentioned above.These data forms can use IMSI or ESN (this can be called out for each by MS and obtain), and go for IMSI or ESN relevant with MS manufacturer/model, defective and performance data.
Therefore in an example application of the principle of the invention, it is undesired that MS may work, and may not determine the location QoS (for example positional accuracy) of the positioning service that requires.Positioning service has very wide application based on QoS.For example an application based on QoS comprises the emergency user fixed point in several meters scopes.Another Application comprises nearest restaurant is positioned in several kilometer range.The emergency user of can not fixing a point may cause the injury to the user, and can not provide QoS can cause the operator to lose income to the subscriber.The location QoS problem that provides and confirm to require is provided the example implementation of describing performance methodology with reference to figure 9.If Location Request stationary positioned QoS (for example being required the MS positional accuracy in 50 meters), this can not realize by default action parameter and control signal.Inventive method can be used for positional accuracy is improved to the level of requirement, and this can realize in the following manner, promptly from performance data library searching known additional information or operating parameter, and realizes control signal according to these data.For example, if realize the assistant GPS defectiveness in specific MS, then method may replace with strengthening observed time difference (E-TOD) localization method.In addition, depend on the QoS of requirement, determine that for the E-OTD position BTS that system can replenish more or less is right.
Therefore, technical staff in the wireless communication field is appreciated that the above-mentioned principle of the invention has advantageously solved the problem relevant with the MS place capacity, this is by determining whether specific MS supports the service that requires, if not, control signal or the additional information of improving the LCS response then can randomly be provided.
Another embodiment
In Figure 10, illustrating on the other hand of the principle of the invention, with the functional block formal description simplified communication system 100.The system 1000 of Figure 10 is similar to the system 200 of Fig. 2.Yet in the example embodiment of the principle of the invention, MS 1040 comprises EIP 1045.In addition, auxiliary or determine to enable MS 1040 for MS based on the location of MS.As definition in the reference 3GPP TS 43.059 that comprises, the MS assist location is Mobility Center localization method (for example E-OTD, A-GPS), wherein MS location estimation from computing network to network that provide position measurement to provide with.Network can provide auxiliary data to MS, to enable position measurement and/or to improve measurement performance.Location based on MS is positioned as any Mobility Center localization method (for example E-OTD, A-GPS), and wherein MS realizes that position measurement and location estimation calculate, and is wherein provided to MS by network for one or two useful or crucial auxiliary datas of these functions.
As described in more detail below, MS 1040 is activated in this embodiment in definite equipment identity information relevant with model with the manufacturer of location-server 1010.MS 1040 uses these information selecting optimum message and parameter sets, with location-server 1010 swap datas.If location-server 1010 has been known as " leak ", then MS 1040 can use data-signal to avoid triggering leak alternatively.In addition, when response during location information requests, MS 1040 can comprise the characteristic of knowing the certain position server and the ability of leak.MS can store the information that is obtained by MS and be used for using in the future.
As illustrating in Figure 10, MS 1040 comprises CPU 1042, memory 1044 and transceiver 1046.Transceiver 1046 allows the transmission and the reception of the data between MS 1040 and remote location, such as audio/video/text communication and programming data, and described remote location such as BSS 1050 or satellite 1060.Antenna 1048 electrically is coupled to transceiver 1046.Generally, CPU 1042 realizes EIP 1045 by the specific instruction set that execution is stored in the memory 1044, though in certain embodiments, the application specific processor that can use separation is to realize EIP 1045.CPU 1042 can carry out the instruction that is stored in the memory 1044.The assembly of MS 1040 is linked together by bus system 1049.
The assembly of location-server 1010 is linked at together by bus system 1018.As above with reference to previous description of drawings, though location-server 1010 is illustrated as in BSS 1050 outsides, it can be contained in BSS1050 or the BSC 1051, or it can be positioned at communication service provider network 1030, or at some in other combinations.
