Description
Technical field
The present invention relates to the mobile management technology in the mobile communication system, relate in particular to a kind of route district (RA)/lane place (LA) update method.
Background technology
In global system for mobile communications (GSM)/GPRS (GPRS) and general mobile network (UMTS) system, the circuit domain (CS) and packet domain (PS) business that can enjoy network provide as the travelling carriage (MS) of terminal.Wherein have a plurality of lane place in the CS territory, each lane place is all represented by unique Location Area Identification (LAI), so that VLR Visitor Location Register (VLR) is determined the position of MS; Have a plurality of routes district among the PS, each route district also represents by unique Routing Area Identifier (RAI), so that packet switch domain service support node (SGSN) is determined the position of MS.A lane place can comprise a plurality of routes district, and a route district comprises a plurality of sub-districts.When MS moves to another lane place by a lane place, must notify core net, make core net know the lane place at this current place of MS, promptly carry out location area updating; When MS changes the route district, also mutual with core net, carry out Routing Area Update.
According to 3G PP agreement, RAI comprises LAI and route district sign indicating number (RAC), and wherein LAI is the prefix of RAI; LAI comprises Mobile Country Code MCC (MCC), mobile network network No. (MNC) and Location Area Code (LAC).Preserve RAI and LAI that this MS the last time succeeds in registration in subscriber identity module among the MS (SIM)/universal subscriber identity module (USIM) card.
When MS is in the following time of network schemer that has Gs interface between VLR and the SGSN, the MS that supports joint route area/location renewal technology is in the lane place or the system of access when changing, initiating the joint route area/location by the Routing Area Update request message (Routing Area Update Request) that sends cells such as carrying updating type (Update Type), former RAI and new RAI to SGSN upgrades, so that lane place and the routing iinformation to system upgrades simultaneously, guarantee getting in touch between communication system and the MS.
According to the 3GPP agreement, updating type is divided into the joint route area/location to be upgraded (combinedRA/LA updating) and has joint route area/location renewal (combined RA/LA updating with IMSI attach) that IMSI International Mobile Subscriber Identity (IMSI) adheres to etc., and the enumerated value of above-mentioned updating type is respectively 1 and 2.
SGSN is after receiving the Routing Area Update request message that comes from MS, the enumerated value of at first judging updating type is 1 or 2, if be 1, then from this message, parse former RAI and new RAI, and from two RAI, obtain former LAI and new LAI, under the former LAI situation different, initiate location area updating then to VLR with new LAI; If the enumerated value of updating type is 2, then SGSN directly initiates location area updating.In other words, SGSN judges that this MS does not change in the occurrence positions district, then can not initiate location area updating to VLR under the former LAI situation identical with new LAI.
In theory, the prefix of the RAI that preserves in the SIM/USIM card should be identical with LAI.But, under such as situations such as MS move back and forth in two communication systems apace, can cause RAI to fail and upgrade.Like this, when MS moves back to former RAI correspondence regional, carry out the joint route area/location and upgrade, make SGSN not initiate the position and upgrade, and then cause circuit domain business to lose efficacy because of erroneous judgement LAI change to VLR.
Summary of the invention
In view of this, the invention provides a kind of routing area/location update method, can when the joint route area/location upgrades, avoid SGSN erroneous judgement and the circuit domain business that causes lost efficacy.

Embodiment
For making purpose of the present invention, technical scheme clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The present invention is a kind of routing area/location update method, its basic thought: the cell value in the route district update inquiry information is made amendment or increase as the MS of terminal, so that after SGSN receives the Routing Area Update request message, ask new VLR to carry out location area updating.
Fig. 1 shows the exemplary process diagram of joint route area/location update method among the present invention.Referring to Fig. 1, this method comprises:
In step 101, when the former RAI prefix of preserving in the travelling carriage and former LAI are inconsistent, the normal Routing Area Update request message that upgrades of this travelling carriage structure expression, and send to SGSN;
In step 102, SGSN asks new VLR to carry out location area updating, and new VLR is according to the request that receives, and is mutual with attaching position register (HLR), former VLR and SGSN, finishes the location area updating of this travelling carriage.
Among the present invention, the mode of the normal Routing Area Update request message that upgrades of MS structure expression comprises: the updating type cell in this message is revised as representative has the enumerated value 2 that joint route area/location that IMSI adheres to upgrades, perhaps the former RAI cell in this message is replaced with invalid value, perhaps former LAI is joined in the Routing Area Update request message as independent cell.Describe below by the routing area/location update method of specific embodiment the foundation inventive concept.
Fig. 2 shows the flow chart of joint route area/location update method in the present embodiment.Referring to Fig. 2, this method comprises:
In step 201, MS reads former RAI and the former LAI that preserves in self SIM/USIM card, and obtain the new RAI of this MS correspondence, whether the prefix of judging the former RAI that is read then is identical with former LAI, if, then send the Routing Area Update request message that carries former RAI and new RAI to SGSN, request SGSN carries out the joint route area/location to be upgraded; Otherwise, whether the prefix of judging former RAI is consistent with the prefix of new RAI, when both are consistent, updating type in the Routing Area Update request message is revised as representative has the enumerated value that joint route area/location that IMSI adheres to upgrades, and the routing update request message that will carry former RAI and new RAI sends to SGSN.
According to the regulation of 3G PP agreement, when changing, starting shooting or arriving report cycle in the residing position of MS, MS sends Routing Area Update message to network side, so that keep in touch with network.And when the numerical value of filling in the updating type cell was 2, what represent this MS initiation this moment was to have the joint route area/location renewal that IMSI adheres to, and promptly this MS changes open state over to by off-mode.In this case, SGSN must send location area updating request (Location Update Request) message to new MSC/VLR after receiving the Routing Area Update request message.This step just is being based on afore mentioned rules, revises the updating type cell, to avoid owing to former RAI prefix and the inconsistent circuit domain business inefficacy that causes of former LAI.
In step 202, SGSN and MS and new MSC/VLR are mutual, carry out the security functions that carries out authentication and/or encryption etc. such as to the user who uses MS.
In step 203, SGSN parses the updating type cell from the Routing Area Update request message that receives, the enumerated value of judging this cell is 1 or 2, if be 1, then when the prefix of former RAI and the prefix of new RAI are inequality, send location area updating message to new MSC/VLR; If be 2, then SGSN asks new MSC/VLR that MS is carried out the joint route area/location and upgrades by sending the location area updating request message.
Because under the prefix of present embodiment and former RAI inconsistent with former LAI in step 201 situation identical with the prefix of new RAI in the prefix of former RAI, the enumerated value of updating type is revised as 2, even then the prefix of former RAI and actual conditions are not inconsistent in this step, SGSN also can send the location area updating request message to new MSC/VLR, initiates the registration of circuit domain.Like this, can fundamentally avoid causing the more new technological process inefficacy of circuit domain position owing to from former RAI, taking out wrong former LAI.
In step 204～209, new MSC/VLR sends update request (Update to HLR
Location) message indicates the user and roams in this new VLR area; HLR sends canceling position (Cancel Location) message to Anchor MSC/VLR, notifies former VLR to delete this MS user information corresponding, and former VLR confirms (Cancel Location Ack) message to the cancellation of HLR home position after finishing deletion; HLR is by inserting user data (Insert Subscriber Data) message, the user contracting data of this MS correspondence is inserted among the new VLR, after new VLR finishes the data insertion, return insertion user data response (Insert Subscriber Data Ack) message to HLR; HLR returns update request response (Location Update Ack) message to new MSC/VLR.
Six message in the above-mentioned steps are optional message, do not exist under the situation of MS corresponding user data in new VLR, are just begun to carry out by step 204.In addition, step 207 and step 208 can be carried out repeatedly, till user data all is inserted among the VLR.
In step 210～211, new MSC/VLR upgrades to SGSN home position district and accepts (Location Update Accept) message, indicates the location area updating of having accepted MS; SGSN sends Routing Area Update to MS again and accepts (Routing Area Update Accept) message.
In step 212～213, MS sends Routing Area Update to SGSN and finishes (Routing AreaUpdate Complete) message, SGSN has heavily assigned Temporary Mobile Subscriber Identity (TMSI) (TMSI Reallocation Complete) message again, indicates in the circuit domain redistributing of TMSI and finishes.
After this, MS upgrade in time RAI and LAI in self SIM/USIM card are so that the prefix of RAI is identical with LAI.
So far, finish the flow process that routing area/location upgrades in the present embodiment.
By above-mentioned flow process as seen, when the prefix of determining the prefix of the former RAI that the SIM/USIM card is preserved in self and former RAI inconsistent with the prefix of former LAI as MS is identical with the prefix of new RAI, the enumerated value of updating type is revised as 2, make SGSN to initiate the circuit domain registration, thereby avoided because of judging the circuit domain position renewal failure that the MS lane place does not change and causes by accident to new VLR.
When employing replaces with the mode of invalid value with former RAI cell, step 201 among Fig. 2 becomes: MS reads former RAI and the former LAI that preserves in self SIM/USIM card, and obtain the new RAI of this MS correspondence, then, whether the prefix of judging the former RAI that is read is identical with former LAI, if, then sending the Routing Area Update request message that carries former RAI and new RAI to SGSN, request SGSN carries out the joint route area/location to be upgraded; Otherwise whether the prefix of judging former RAI consistent with the prefix of new RAI, when both are consistent, former RAI is revised as invalid value, and will carry amended former RAI and newly the Routing Area Update request message of RAI send to SGSN.Here the method that former RAI is revised as invalid value can be that the LAI with former RAI partly is revised as 0000 or FFFF etc.
Further comprise between step 201 and 202: SGSN parses former RAI and new RAI from the Routing Area Update request message that receives, determine that this former RAI is invalid, then by carrying out implicit detach alternately with MS; Then the former RAI prefix of preserving in the SIM/USIM card of MS is changed into identically with former LAI, and then MS sends former RAI after carrying change and the Routing Area Update request message of new RAI to SGSN, and the enumerated value of the updating type in this message is 2.
After this, carrying out the joint route area/location according to the step 202 among Fig. 2～step 213 upgrades.
Former RAI is revised as under the mode of invalid value in above-mentioned employing, also can be under the prefix and the inconsistent situation of former LAI of former RAI, guarantee that SGSN sends location area updating message to new VLR, register in the start-up circuit territory, thereby avoid the inefficacy of circuit domain business in the renewal of joint route area/location effectively.
Adopting when former LAI joined mode in the Routing Area Update request message as independent cell, step 201 among Fig. 2 becomes: MS reads former RAI and the former LAI that preserves in self SIM/USIM card, and obtain the new RAI of this MS correspondence, whether the prefix of judging the former RAI that is read then is identical with former LAI, if, then send the Routing Area Update request message that carries former RAI and new RAI to SGSN, request SGSN carries out the joint route area/location to be upgraded; Otherwise, judge whether the prefix of former RAI is consistent with the prefix of new RAI, when both are consistent, send the Routing Area Update request message that carries former RAI, new RAI and former LAI to SGSN.
At this moment, step 203 becomes: SGSN parses the updating type cell from the Routing Area Update request message that receives, the enumerated value of judging this cell is 1 or 2, if be 1, then when the prefix that reads former LAI cell and former LAI and new RAI is inequality, the prefix that does not perhaps read former LAI and former RAI when inequality, sends location area updating message to new MSC/VLR with the prefix of new RAI; If be 2, then SGSN asks new MSC/VLR that MS is carried out the joint route area/location and upgrades by sending the location area updating request message.
After this, carrying out the joint route area/location according to step 204 shown in Figure 2～213 upgrades.
Under the mode that LAI is joined as cell independently in the Routing Area Update request message, also can be under the prefix and the inconsistent situation of former LAI of former RAI, guarantee that SGSN sends location area updating message to new VLR, register in the start-up circuit territory, thereby avoid the inefficacy of circuit domain business in the renewal of joint route area/location effectively.
In above-mentioned modification or increase in the scheme of the cell in the Routing Area Update request message, whether the prefix that also can omit prefix that MS judges former RAI and new RAI uniform operation.
Fig. 3 shows the schematic diagram that MS moves in UMTS and two communication systems of GSM.As shown in Figure 3, MS corresponding LAI in the UMTS communication system is that 46008A002, RAI are 46008A00222; LAI corresponding in gsm communication system is that 46008A001, RAI are 46008A00111.
MS at first registers in the UMTS network, and after succeeding in registration, the former LAI that preserves in the usim card of this MS is 46008A002, and former RAI is 46008A00222.MS moves in the gsm communication system then, and after MS carried out the location area updating success by the circuit domain registration, the former LAI that preserves in the usim card was 46008A001.MS carries out Routing Area Update by the packet domain registration again in GSM, but this Routing Area Update imperfect tense, and MS comes back in the UMTS communication system, and the former RAI that then preserves in the usim card remains 46008A00222.MS determines that variation has taken place for self residing communication system and lane place, and MS present located UMTS communication system is under the network schemer that has Gs interface between VLR and the SGSN, and then MS initiates the joint route area/location and upgrades.
According to the method in the embodiment of the invention, MS judges that to prefix and the former LAI of the former RAI that preserves in the usim card because former RAI is 46008A00222, former LAI is 46008A001, and then the prefix of former RAI and former LAI are inconsistent.And because new RAI is 46008A00222, then the prefix of former RAI is identical with the prefix of new RAI.So, MS can be revised as updating type representative and have the routing area/location renewal enumerated value 2 that IMSI adheres to, and this enumerated value, former RAI=46008A00222 and new RAI=46008A00222 are carried in the Routing Area Update request, sends to SGSN; It is behind 2 the Routing Area Update request message that SGSN receives the updating type enumerated value, initiates location area updating to new VLR.MS 1 is carried in the Routing Area Update request, sends to SGSN; SGSN carries out implicit detach to this MS, and after the former RAI that preserves among the USIM of this MS was updated to and equals 46008A00111, MS sent the Routing Area Update request message to SGSN again, and SGSN initiates location area updating to new VLR again.In addition, MS 1 is carried in the Routing Area Update request, sends to SGSN; SGSN determines that by the prefix of more former LAI and new RAI variation has taken place in the lane place of this MS, then initiates location area updating to new VLR.
By the example among Fig. 3 as seen, in the time of can avoiding the prefix of former RAI and former LAI not to be inconsistent according to the routing area/location update method of inventive concept, SGSN does not send the location area updating request message to new VLR because of judging by accident to break, thereby causes the situation that circuit domain business lost efficacy in the renewal of joint route area/location.Like this, both guarantee the compatibility of network, improved the networking capability of GSM/GPRS and UMTS communication system again, remedied the defective that has the network schemer of Gs interface between VLR and the SGSN.And the method among the present invention has significantly reduced owing to the prefix of former RAI and inconsistent cause called of former LAI and can't connect, and has improved the service quality of wireless communication system, improves user's satisfaction.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
