Description
Technical field
The present invention relates to moving communicating field, particularly the control method of location of mobile station location.
Background technology
For mobile communication carrier, positioning service (LCS:Location Service) can help their monitoring network operation conditions better, understands the distribution of telephone traffic, optimizes the network planning, assists mobile subscriber's handover.What is more important, LCS itself has constituted a business platform, and it can help the mobile subscriber to customize all kinds of services relevant with the position, as information services such as the inquiry service facility close with own position, hotel, market, gas stations.This can strengthen its competitiveness for mobile communication network operator finds more point of economic increase undoubtedly.
For the mobile subscriber, benefit is self-evident naturally.Because the user can be outside original voice service, acquisition and personal security, Emergency Assistance, ecommerce, the business that trip is relevant with respective services such as tourism and amusements.They not only can see position of oneself and the position that will search service facility easily on the shown map of the display screen of mobile phone, also can authorize other people to inquire about the positional information of oneself, ensure the personal safety of oneself.
The functional block diagram of LCS technology in existing GSM/GPRS network as shown in Figure 1, the major function entity that relates to has:
LCS client (LCS Client) is meant the user who sends inquiry a certain target MS (MS:MobileStation) position requests.It can be MS oneself, also can be the management system in the network, can also be the user outside this land mobile communication network network (PLMN:public land mobile network).
Gateway Mobile Location Center (GMLC:Gateway Mobile Location Center), for the LCS client outside the PLMN, GMLC is first node that the LCS service is run in its visit GSM net.GMLC will be to attaching position register (HLR:Home Location Register) inquiry routing iinformation.GMLC also registers and authentication LCS client, for providing service through the LCS request of authorizing.Subsequently, GMLC issues network subsystem (NSS:Network Sub System) with the LCS service request, and obtains final locating information from NSS.According to the effect in position fixing process, GMLC can be divided into three types: request Gateway Mobile Location Center (R-GMLC:Requesting-GMLC), and it is positioned at the on-site GMLC of LCS client; Home gateway mobile positioning center (H-GMLC:Home-GMLC), it is positioned at the GMLC of the ownership of target MS; Visit Gateway Mobile Location Center (V-GMLC:Visited-GMLC), it is positioned at the GMLC of target MS visit.Interface by standard between them is connected.
NSS comprises location related functional entities and other functional entitys such as mobile services switching centre (MSC:Mobile Switching Centre), Serving GPRS Support Node (SGSN:Serving GPRS Support Node), HLR.NSS mainly is responsible in position fixing process: the charging of positioning service, the coordination of positioning service, authentication, and accept the Location Request of GMLC, in the position fixing process in packet switching (PS:PacketSwitching) territory, NSS also is responsible for location related data and signaling between relay services mobile positioning center (SMLC:Serving Mobile Location Center) and the MS.
Base station sub-system (BSS:Base Station Subsystem) mainly comprises base station transceiver system (BTS:Base Transceiver Subsystems) and base station controller (BSC:Base StationController).Concrete location technology process is mainly realized jointly by BSS, Location Measurement Unit (LMU:LocationMeasurement Unit) and SMLC.
SMLC is one of most important component in the LCS service.SMLC is responsible for coordinating cooperatively interacting between target MS, LMU and other LCS resource.Its starts the request that target MS is positioned functions such as the signal measurement that will carry out, position calculation.And final estimation and compute location result and precision.SMLC can be used as the separate physical entity and exists, and also may reside among the BSC.
LMU finishes wireless signal is measured.LMU is related with a specific SMLC.LMU measures special wireless according to the instruction from SMLC.As Fig. 1, LMU can be used as separate physical entity LMU (A) and exists, and also can be present among the BTS for LMU (B).
CBC (CBC:Cell Broadcast Center), some localization method SMLC need be given MS some measurement auxiliary parameters, and CBC obtains broadcast data from SMLC, is broadcast to MS by BSS then.
Positioning service generally is to be initiated by LCS client, and the network at request target MS place is measured, then return results.
Process flow steps in the GMLC side is as follows:
A1.R-GMLC receives LCS client and initiates the LCS request;
A2.R-GMLC confirms LCS client's sign and the location-based service that this client orders, the identifier that data that provide according to LCS client and order data obtain target MS, this identifier is international mobile subscriber identity (IMSI:International Mobile Subscriber Identification Number), a kind of in travelling carriage ISDN number (MSISDN:Mobile Station International ISDN Number) or the pseudo-code, ISDN is the abbreviation of integrated services digital network (Integrated Services DigitalNetwork), and the service quality of current LCS (QoS:Quality of Service) comprises positioning service precision and LCS QoS rank (LCS QoS Class);
If A3. the R-GMLC in the A2 step is not the H-GMLC of target MS, then find the H-GMLC route, and send the LCS request to H-GMLC by HLR, comprise LCS QoS (positioning service precision and LCS QoS Class) in the request message;
A4. can the H-GMLC of target MS will verify the positional information that obtain target MS, and H-GMLC also asks to carry out privacy inspection according to the private template (PP:privacy profile) of the MS that preserves to LCS.PP is the constraints that MS is stored in the positioning service among the H-GMLC, such as needing notification target MS in the acquisition position.Privacy checks purpose is to check whether the LCS Location Request satisfies these constraintss, and the LCS request that only satisfies condition could continue ensuing positioning flow.
If A5. H-GMLC finds target MS not in the current service scope, it may find the V-GMLC at target MS place by HLR so, and send Location Request to V-GMLC, comprise LCSQoS (positioning service precision and LCS QoS Class) in the request message;
Can A6.V-GMLC will at first confirm have the right to obtain the positional information of target MS, if then continue to carry out handling process in the NSS side, otherwise return the LCS failure.
Among the above-mentioned steps A2, LCS QoS is sent out in LCS QoS information unit (IE:Informa tion Element), comprising LCS QoS Class, its value implication is defined as: best endeavors state (BestEffort)=0, require network to position according to the ability of maximum, and reported result, the precision of reported result does not satisfy the positioning service precision and has no relations yet; Affirmation state (Assured)=1: must reach qos requirement and just report positioning result.
In existing NSS effluent journey as shown in Figure 2:
B1.V-GMLC sends request location of mobile station message to MSC/SGSN, comprises information such as the identifier of location information request, target MS of needs and LCS QoS IE in the message;
This MS of B2.MSC/SGSN paging, and carry out processes such as authentication, encryption safe;
If B3. Location Request is from the LCS client of increment type, and private associative operation or MS order service template require must notice MS about information such as positional information type, LCS customer IDs, MSC/SGSN will send LCS location notification message to MS so;
B4.MS returns LCS location push-notification-answer message;
B5.MSC/SGSN sends the Location Request order to BSS, and BSS carries out position fixing process and return results, and its idiographic flow as shown in Figure 4;
B6.MSC/SGSN returns the request location of mobile station and responds to V-GMLC.
Among the above-mentioned steps B1, coding structure such as Fig. 3 of LCS QoS IE do not comprise LCS QoS Class.
Figure 4 shows that existing BSS executing location positioning flow figure:
C1.MSC/SGSN sends locating request message to BSS, generally includes the identifier of target MS, sign, align_type and the LCS QoS IE of sub-district, place in this message, waits for that BSS replys the result;
C2.BSS is according to Base Station System Application Part LSC Extended Protocol (BSSAP-LE:Base StationSystem Application Part LCS Extension), send locating request message to SMLC, generally include align_type, cell ID and LCS QoS in the message, BSS waits for that SMLC replys positioning result then;
C3.SMLC carries out position fixing process;
After C4.SMLC obtained the result, restoring to normal position responded to BSS;
C5.BSS is transmitted to MSC or SGSN to positioning result.
Among above-mentioned steps C1 and the C2, identical among the coding structure of LCS QoS IE and the step B1 do not comprise LCS QoS Class yet.If SMLC positions target MS, as shown in Figure 5, BSS discovery travelling carriage is striden the sub-district switching of BSS, or strides BSS sub-district or Routing Area Update.At this moment, will receive that at step D2.BSS the location that MSC/SGSN sends withdraws from message; Step D3.BSS also will send the location to SMLC and withdraw from message; Step D4.SMLC will reply the BSS location response.All there is not LCS QoS Class in the locating request message that BSS and SMLC receive, therefore SMLC replys in the message whether carry existing positioning result, decide in its sole discretion by SMLC, and the BSS message that replies to MSC or SGSN just can be sent after need receiving the answer message of SMLC.
Different LCS is different to the requirement of positioning service precision: some LCS must be met the position result of accuracy after the Location Request of initiating target MS, ungratified words then do not need the result; Some LCS requires not strict to the result, do not satisfy under the required precision situation in existing result, also can accept.For the previous case, although SMLC obtains the required precision that positioning result can not satisfy LCS client when position fixing process is dropped by the wayside.But according to prior protocols, SMLC can determine whether reply existing positioning result, and this just may cause SMLC to reply the IE waste in the message and construct the IE waste of time.For latter event, when withdrawing from position fixing process, SMLC has obtained preliminary positioning result, and this moment, SMLC might determine to reply an alignment error message to BSS.Caused the waste of navigation system signaling process and processing like this.

0: best endeavors state (Best Effort)
1: affirmation state (Assured)
The LCS QoS Class of V-GMLC to MSC/SGSN Location Request, this field can be placed among the bit 3 of Octet 3 of LCS QoS IE, also can be placed on other idle bits (sparebit) of Octet 3, also can be placed on arbitrary idle bit of Octet 6 of LCS QoS IE.Further, LCS QoS Class can also be placed among other IE of locating request message or among the new IE that adds, as long as these IE can be placed on Location Request.
As Fig. 7, first embodiment of the invention localization process flow chart:
F1.V-GMLC carries LCS QoS Class in the LCS QoS IE that location of mobile station message is provided to MSC/SGSN transmission request;
F2.MSC/SGSN sends the localization process request to BSS, and BSS sends the localization process request to SMLC;

F3. do you judge whether MSC/SGSN receives the cell switching information of striding BSS, or stride BSS sub-district or Routing Area Update message? if execution in step F4 then, otherwise execution in step F9.
If current positioning service is undertaken by MSC, when switch the sub-district of then striding BSS, BSS will send the cell switching information of striding BSS to MSC, at this moment can cause the loss of positioning service precision, need whether end to make judgement to position fixing process.
Equally,, then stride the loss that BSS sub-district or Routing Area Update also can cause the positioning service precision, need whether end to make judgement position fixing process if current positioning service is undertaken by SGSN.
F4.MSC/SGSN sends the location to BSS and withdraws from message, and BSS sends the location to SMLC and withdraws from message;
MSC or SGSN send the location to the BSS at travelling carriage place and withdraw from message, and BSS withdraws from message to its SMLC transmission location, to end current SMLC location survey.
Does F5.MSC/SGSN judge that current LCS QoS Class is Assured? if illustrate that current measurement must satisfy the positioning service precision, execution in step F6 then, otherwise execution in step F7;
F6.MSC/SGSN sends location response message to V-GMLC, wherein comprises location failure indication.
Because receive the cell switching information of striding BSS at MSC/SGSN, or stride under the situation of BSS sub-district or Routing Area Update message, therefore the inevitable requirement of not satisfying the positioning service precision of good location accuracy can be returned failure in advance here, thereby save the flow processing time.
F7.SMLC reports BSS with existing positioning result, if do not have then report the location failure response;
Report the positioning result that has drawn as far as possible, improve resource utilization, if but, then report the location failure at present without any positioning result.
F8.BSS reports location response message to MSC/SGSN, and MSC/SGSN reports V-GMLC with response message;
F9.SMLC reports location response message according to good location accuracy and positioning service precision to BSS;
Do not receive the cell switching information of striding BSS at MSC/SGSN, or stride under the situation of BSS sub-district or Routing Area Update message that the requirement that positioning result must satisfy the positioning service precision just can report.Whether the positioning result of judging SMLC satisfies the positioning service required precision, if then positioning result is reported BSS, otherwise reports the location failure response.
F10.BSS reports location response message to MSC/SGSN, and MSC/SGSN is with location response information reporting V-GMLC.
Wherein step F 4, F5, F6, F7, F8 withdraw from operation for the location, and step F 9, F10 do not withdraw from operation for there being the location.
Further, MSC/SGSN to BSS and BSS to SMLC Location Request also comprise LCS QoSClass, and the coded system of LCS QoS Class field in IE is the same with LCS QoS Class in V-GMLC to the MSC/SGSN Location Request.
As Fig. 8, second embodiment of the invention localization process flow chart, the steps different with first embodiment are described below:
G2.MSC/SGSN sends the localization process request of carrying LCS QoS Class to BSS, and BSS sends the localization process request to SMLC;
LCS QoS Class is further sent to BSS.
Does G5.BSS judge that current LCS QoS Class is Assured? if illustrate that current measurement must satisfy the positioning service precision, execution in step G6 then, otherwise execution in step F7;
G6.BSS reports location failure response message to MSC/SGSN, and MSC/SGSN sends location response message to V-GMLC, wherein comprises location failure indication.
Report the location failure by BSS to MSC/SGSN, MSC/SGSN sends location response message according to judgement and the failure response message of BSS to V-GMLC, wherein comprises location failure indication.
Wherein step F 3, F4, G5, G6, F7, F8, F9, F10 are positioning action, and step F 4, G5, G6, F7, F8 withdraw from operation for the location, and step F 9, F10 do not withdraw from operation for there being the location.
BSS is after withdrawing from message to SMLC transmission location, and according to the LCS QoSClass of this LCS QoS IE, if " Best Effort ", BSS will wait for after SMLC replys positioning result and again this result be replied to MSC or SGSN so; If be " Assured ", BSS just can reply MSC or SGSN, and not need to wait for that SMLC replys after withdrawing from message to SMLC transmission location so.
As Fig. 9, third embodiment of the invention localization process flow chart is described below with above two different steps of embodiment:
H2.MSC/SGSN sends the localization process request of carrying LCS QoS Class to BSS, and BSS sends the localization process request of carrying LCS QoS Class to SMLC;
LCS QoS Class is further sent to SMLC.
Does H5.SMLC judge that current LCS QoS Class is Assured? if illustrate that current measurement must satisfy the positioning service precision, execution in step H6 then, otherwise execution in step F7;
H6.SMLC reports location failure response message to BSS, and BSS reports location failure response message to MSC/SGSN, and MSC/SGSN sends location response message to V-GMLC, wherein comprises location failure indication;
H9.SMLC reports location response message according to good location accuracy, positioning service precision and LCS QoS Class to BSS.
Do not receive the cell switching information of striding BSS at MSC/SGSN, or stride under the situation of BSS sub-district or Routing Area Update message.If LCS QoS Class is Best Effort, then SMLC also can report the positioning result that does not satisfy the positioning service precision, reaches the effect that improves resource utilization like this.Do not satisfy the positioning service required precision so judge the positioning result of SMLC here, and current LCS QoSClass is Best Effort, the positioning result that then will not satisfy the positioning service required precision reports BSS.
Wherein step F 3, F4, H5, H6, F7, F8, H9, F10 are positioning action, and step F 4, H5, H6, F7, F8 withdraw from operation for the location, and step H9, F10 do not withdraw from operation for there being the location.
