Description
Technical field
The present invention relates to a kind of mobile communication system, relate in particular to a kind of in mobile communication system the shift position business based on user plane.
Background technology
If locating platform (LSP, Location Service Platform) the location-based business (LBS in, Location Based Service) user, both comprised AGPS (Assisted Global PositioningSystem, agps system) terminal use, comprise non-AGPS terminal use again, such as the common cellphone user of only supporting sub-district ID (Cell-ID) location technology, LSP just must correctly judge type of user terminal so, to select suitable location technology or positioning flow, the LSP here can be GMLC, MPC or SLC etc.Otherwise, may cause location failure, positioning accuracy to reduce or locate problem such as lengthening consuming time, such as: if the AGPS portable terminal is adopted Cell-ID location, then positioning result low precision; If common mobile terminal is adopted the AGPS location, then can fail in the location; If all adopt first AGPS to locate the method for Cell-ID location to all portable terminals, then common mobile terminal user's locating speed may reduce several times again.
With regard to one side, prior art related to the present invention is as follows:
(1) based on the AGPS location technology of user plane
The AGPS location is to a kind of distortion of GPS position application behind mobile communications network, it is by being provided the method for satellite assistance data in advance to portable terminal by network, shortened portable terminal positioning time greatly, the power consumption problem of avoiding portable terminal long-time continuous location to be caused.At present, be positioned with two kinds of standards based on the AGPS of user plane, one is international standard OMA SUPL, and another is Qualcomm
TmThe standard GPSOne of company
TmTheir positioning flow is similar, and concrete steps as shown in Figure 1.In step 101, LSP notifies portable terminal by short message service (SMS) or WAP Push (WAP Push), requires this portable terminal initiatively to initiate the AGPS Location Request to the LSP of appointment by IP network; In step 102, this portable terminal is initiated Location Request by the IP mode to LSP, and reports the information such as Position Approximate, stationkeeping ability of portable terminal; In step 103, LSP pushes auxiliary data and gives this portable terminal; In step 104, portable terminal is finished the location and will be issued LSP on the positioning result.
Obviously, can not discern the notification message that LSP issues in a large amount of common mobile terminal of using on the market, these terminals can not report oneself not to be the AGPS portable terminal to LSP.
(2) sub-district ID (Cell-ID) location
Cell-ID for non-AGPS portable terminal is positioned with multiple implementation, and wherein relatively commonly used have MAP-ATI mode and 0371 mode (based on 3GPP 03.71 agreement).Fig. 2 illustrates the positioning flow of 0371 mode.In step 201, LSP sends inquiry (MAP_Any_Time_Interrogation) request to HLR (attaching position register); In step 202, HLR sends user profile to VLR (Visited Location Registor) and (MAP_Provide_subscriber_Information) request is provided and receives response; In step 203, HLR returns inquiry (MAP_Any_Time_Interrogation) to LSP and replys, and comprises customer position information during this is replied; In step 204, LSP judges that user profile is overtime, sends routing iinformation (MAP_Send_Routing_Info_For_SM) and receives response to HLR; In step 205, LSP sends the not short message and the reception response of content to the MSC at user place (mobile switching centre); In step 206, LSP resends inquiry (MAP_Any_Time_Interrogation) request to HLR; In step 207, HLR sends user profile to VLR and (MAP_Provide_subscriber_Information) request is provided and receives response; In step 208, HLR returns inquiry (MAP_Any_Time_Interrogation) to LSP and replys, and LSP obtains final customer position information.
Obviously, Cell-ID positioning flow and AGPS have than big-difference.Also have than big-difference at other Cell-ID positioning flow of common mobile terminal with AGPS.Therefore, LSP must at first distinguish the type of portable terminal, could adopt suitable positioning flow to come localisation of mobile terminals then.
With regard on the other hand, two kinds of fairly simple prior aries are arranged, can partly satisfy same locating platform and support location simultaneously AGPS terminal and non-AGPS terminal, but their defectiveness all.
(1) first AGPS, back Cell-ID:
For each positioning flow, owing to do not know the stationkeeping ability of portable terminal, so LSP always attempts earlier portable terminal is carried out the AGPS location, if the location failure (ordinary circumstance be that terminal is overtime do not respond), then again this portable terminal carried out the Cell-ID location.
For the AGPS mobile phone users, this method is friendly.But for non-AGPS mobile phone users, positioning time is lengthening significantly, is very disagreeableness.If it is very big that AGPS user accounts for all LBS users' ratio, this method is feasible.If ratio is little, this method is not suitable for.
(2) initiatively declared the type of the portable terminal of oneself by the user, locating platform is judged in view of the above:
The type that the user initiatively declares the portable terminal of oneself when opening the LBS business is such as being AGPS or non-AGPS, the mobile terminal style of LSP recording user.In positioning flow, LSP selects corresponding location technology according to the mobile terminal style of the user in the record, and the user is positioned.
But, when the user is replaced by non-AGPS portable terminal by the AGPS portable terminal, when perhaps being replaced by the AGPS portable terminal by non-AGPS portable terminal, if there is not the type of the original statement of portable terminal in the time update LSP record, then location meeting failure or precision reduce.
