Abstract
The invention provides a method for disposing collision of paging and position uptating, a MSC and VLR. The method includes steps: A, when the MSC tests collision of paging and position uptating of the terminal, the MSC sends the paging failing message for indicating the terminal to generated the collision of paging and position uptating to VLR; B, after receiving the message, the VLR hangs the paging service course of the terminal, disposes the position uptating service of the treminal; C, after the terminal finishes position uptating service, the VLR activates and executes the hung paging service, calls the terminal. Through the method, the MSC and the VLR, the success rate and the satisfaction degree of the mobile communication system can be improved.
Description
Technical field
The present invention relates to the paging technique of moving communicating field, relate in particular to the processing method, (MSC of mobile switching centre of a kind of paging and location update confliction, Mobile Switching Center) and VLR Visitor Location Register (VLR, Visitor Location Register).
Background technology
(Location Updating) upgraded in the position and paging (Paging) is two kinds of common processes in the mobile communcations system.Simply introduce earlier the notion of position renewal and paging.
The position is updated in third generation partner program (3GPP, the 3rd Generation PartnershipProject) agreement and is called as the specific flow process of MM (Mobile Management Specific Procedures).The specific flow process of MM can be divided into again: normal position is more new technological process (periodic updating) and IMSI attachment flow (IMSI attach) of new technological process (normal location updating), periodic position more.Position more new capital is initiatively to be initiated by terminal, and normal position is upgraded and to be meant and to initiate when terminal moves to different lane place, to network side (Network) reporting terminal present located lane place; Periodic location update is periodically to be in active state to the network side reporting terminal.The IMSI attachment flow is meant that terminal powers on.Three kinds of positions more new technological process are the same basically in view of signaling, unique difference is to have a parameter to be used to refer to the position updating type in location update request message (LOCATIONUPDATINGREQUEST), upgrade for different types of location, the content that this parameter comprised is different.More new technological process of these three kinds of positions of general reference is upgraded in the follow-up herein position of mentioning.The signaling process that the position is upgraded please refer to Fig. 1, may further comprise the steps:
Step 101, terminal sends location update request message to MSC;
Step 103, VLR initiates the position to attaching position register (HLR, Home Location Register) and upgrades (MAP Update Location);
Step 105, after the insertion user data was finished, VLR echoed and answers (MAP Insert Subscriber DataAck) message;
After step 106, position were upgraded and finished, HLR put to upgrade to the MSC return and accepts message;
Step 107, MSC upgrades the position and accepts forwards to terminal, and the position is upgraded and is finished.
Paging (Paging) process is meant that it (is called when for example calling out that terminal is done when called under idle condition (IDLE), during short message a side who receives note), network side is managed applying portion (RANAP) message at Iu mouth (MSC and wireless controller (RNC by wireless access network applying portion (BSSMAP) message at A interface (interface between MSC and the base station controller (BSC)) or by base station sub-system, Radio Network Controller) interface between) broadcasts the searching user to user position district (LocationArea), if terminal called returns page-response message (Page Response), can continue to handle the calling access procedure so.Concrete signaling process please refer to Fig. 2, may further comprise the steps:
Step 20l, GMSC (gateway mobile switching center) (GMSC, Gateway Mobile Station Center) sends initial address message (IAM) to the MSC of end office (EO);
Step 202, MSC transmits into call request to VLR, and request VLR checks that the user's goes into to call out authority (SIFIC);
Step 203, VLR checks that the user initiates paging request (PageReq) to MSC after going into to call out authority;
Step 204, MSC all RNC in the district of user position initiate paging (Paging);
Step 205, RNC initiates paging (Paging) to terminal by the base station on paging channel;
Step 206, terminal receive that the paging request returns page response (Page Response) message later on;
Step 207 initiates to insert request (Process Access Req) message to VLR after the MSC paging success, and the request user inserts;
Step 208, after access was finished, VLR went into to finish (Process Access Ack) message to the MSC tieback;
Step 209, VLR returns into access success response (SIFICACK) message to MSC simultaneously after access is finished;
Step 210, MSC issues a layer Three S's etup message to terminal.
Owing to stipulated that the priority of the specific flow process of MM is the highest in 3GPP 24008 agreements, not allowing to set up new MM in the specific flowchart process of MM connects, that is to say and do not allow to carry out other business, and also stipulate for the paging flow process can only paging to be in the terminal of idle condition in the agreement, that is to say if terminal is just being upgraded in the position and can not handle paging (Paging) message, promptly terminal is can not be as called in the renewal process of position.But, in actual conditions, will inevitably upgrade and the simultaneous situation of paging the location, particularly adjacent area, boundary or user are in the high-speed mobile process in the lane place, and the generation of this situation is more common.In fact the position is upgraded and the concurrent situation of paging has following two kinds: 1, terminal is being handled the position more during new business, and network side is found this terminal of other customer calls, and specifically signaling process please refer to Fig. 3; 2, network side terminal when issuing Paging Messages-Waiting Page Response is just initiated the position renewal, and concrete signaling process please refer to Fig. 4.According to the regulation of present agreement, can only be to allow the position to upgrade in this case, and make paging failure, and then make call failure.Analyze prior art below in conjunction with Fig. 3 and Fig. 4 and upgrade processing when clashing in paging and position.
Wherein, in position updating process, receive paging processing of request step as shown in Figure 3, comprising:
Step 301, terminal are initiated the position and are upgraded, and by RNC location update request message are issued MSC;
Step 303, MSC receives initial address (IAM, the Initial Address message) message of GMSC;
Step 304, MSC transmits into call request (SIFIC, Send Info for Incoming Call) message and gives VLR;
Step 305, VLR checks called user subscription information, gives MSC if can be used as called then send paging request (Page Req) message, requires MSC to the RNC issuing page message;
Step 306, MSC receives paging request message, find that the user is carrying out more new business of position, return paging failure (Page MS negative response) message to VLR, cause value extends this as Network Determined User Busy (NDUB, Network Decide User Busy), represent that the user is carrying out the position renewal and can't insert calling;
Step 307, VLR transmits into call request failure (SIFIC NACK, Send Info forIncoming Call Negative ACK) message to MSC;
Step 308, MSC sends to GMSC and discharges (REL) message;
Step 309, the position was upgraded and can be continued this moment, and after the position was updated to merit, VLR sent the position renewal to MSC and accepts message;
Step 310, MSC accepts message with the position renewal and sends to terminal.Finish position more new technological process.
Wait for that behind issuing page message treatment step comprised as shown in Figure 4 when the terminal trigger position upgraded in the page response process:
Step 401, MSC receives initial address (IAM) message of GMSC;
Step 402, MSC transmits into call request (SIFIC) message and gives VLR;
Step 403, VLR checks called user subscription information, gives MSC if can be used as called then send paging request (Page Req) message, requires MSC to the RNC issuing page message;
Step 404, MSC checks the current idle condition that whether is in of terminal, if then issuing page message is given the RNC of (LAI) in the district of terminal present position;
Step 405, RNC receives after the beep-page message of MSC, sends the Paging message of broadcast type on paging channel to terminal by the base station;
Step 406, terminal had triggered the position renewal before receiving beep-page message, send location update request message by RNC to MSC;
Step 407, MSC receives the location update request message of terminal, sent Paging message for before finding this terminal, and be in the state of waiting for page response, according to position new business principle of priority more, the MSC on-position is upgraded, and returns paging failure (Page MS negative response) message to VLR, cause value extends this as Network Determined User Busy (NDUB), and the expression user is carrying out the position renewal can't insert calling;
Step 408, on the other hand, the MSC on-position is new business more, sends location update request message to VLR, and the position of request VLR processing terminal is new business more;
Step 409, VLR receives that paging failure (the Page MS negative response) message of MSC transmits into call request failure (SIFIC NACK) message to MSC afterwards;
Step 410, MSC sends to GMSC and discharges (REL) message;
Step 411, on the other hand, VLR sends the position renewal to MSC and accepts message after position renewal Business Processing is finished;
Step 412, MSC upgrades the position and accepts forwards to terminal, and the position is upgraded Business Processing and is finished.
As can be seen from the above analysis, upgrade the situation of back paging for first position, MSC handles as network busy, directly return paging failure (Page MS negative response) message to VLR, for the news more of position after the first paging, when receiving position updating request, MSC judges that the user is in the page response state of waiting for, also handle, directly return paging failure (Page MS negativeresponse) message to VLR as network busy.This shows, in the prior art, when position renewal and the conflict of paging flow process occurring, upgrading principle of priority according to the position must make the paging flow process fail, and then making call failure, this conflict processing method also can cause the offending sensation of user when reducing call successful rate.
