The MSC/VLR reports the location area information of the user to the home location register (HLR) for recording. When called, the HLR sends the location area information of the called user to the visited MSC/VLR, and the visited MSC/VLR sends paging to the user according to the location area information of the called user sent by the HLR. Because the MSC/VLR can use the location area information sent by the HLR when the user is called, there is no need to add additional backup devices to back up the user information, and the MSC/VLR preferentially uses the user location information in the MSC/VLR when sending paging, The phenomenon of "active-active" and "multi-active" in the prior art is effectively avoided, and the problem of impact on the air interface channel is solved more simply and effectively.
Description
Technical field
The present invention relates to moving communicating field, particularly a kind of method of calling called subscriber, system and mobile switching center (MSC/VLR).
Background technology
In mobile communication system, the entity of preserving user data has two, and one is user's attaching position register (HLR, Home Location Register), and one is user's VLR Visitor Location Register (VLR, Visitor Location Register).The signatory mobile subscriber's of HLR management information, all customer data all leaves among the HLR, wherein records the current VLR address of visiting of user.Deposit the user data that the mobile subscriber who visits this VLR is used for doing calling or other purpose among the VLR, wherein writing down the address, lane place at user place.User data among the HLR is static, permanent in user's time to live; User data among the VLR is dynamic, just exists when having only the user to roam in this VLR.VLR and mobile switching centre (MSC) are corresponding one by one generally speaking, and are among the same physical entity MSC/VLR, finish functions such as the preservation of user data and paging delivery, so, at this MSC/VLR is discussed as a device.
Owing to resetting that MSC/VLR upgrades, fault is restarted or other reason causes, can cause being kept at originally user data loss a large amount of among the MSC/VLR, at this moment, when the user who loses user data in MSC/VLR is done calling, following several paging processing mode is arranged:
First kind of mode: because this user data of users not among the MSC/VLR of visit, calling system is directly pointed out failure.This mode this user data of users not among the MSC/VLR before the user carries out location registers once more so can't do calledly, is a poorest a kind of processing mode.
The second way: because this user data of users not among the MSC/VLR of visit, MSC/VLR will be in the scope of this MSC/VLR administration distributing paging, if paging success then set up and call out, otherwise paging failure.Because, under normal circumstances MSC/VLR is only to the lane place at user place distributing paging, so, among the MSC/VLR not under the situation of this called party data the scope of distributing paging enlarge than under the normal condition, cause the message traffic surge of open paging channel, resource scarcity occurs.If what networking was used is MSC pond mode, then this problem will be more for outstanding.Wherein, when being MSC pond mode, comprise a plurality of MSC, this moment, the impact that open paging channel is caused was also bigger to bigger in requisition for the scope that issues.
The third mode: MSC/VLR has backed up user data before losing user data, MSC/VLR loses behind the user data can restoring user data, MSC/VLR still can accurately carry out paging to the lane place to the user, the shock problem that when therefore, this method has solved calling called subscriber open paging channel has been caused.But this processing more complicated, system will ceaselessly back up and recover, even will additionally increase alternate device.And during MSC/VLR broke down, the user had registered to other MSC/VLR, and this MSC/VLR also thinks the user by mistake in this MSC/VLR after recovering, and this moment can occur " dual-active " or " live " phenomenon more." dual-active " is meant that a user data of users appears among two MSC/VLR simultaneously; " live " is meant that a user data of users appears among a plurality of MSC/VLR simultaneously more.When " dual-active " or " live " phenomenon occurring, can cause the called difficulty of user equally more.For example the user is originally in the scope that MSC/VLR1 covers, there is this user's data among the MSC/VLR1, when MSC/VLR1 breaks down, the user has by chance roamed in the scope of MSC/VLR2 covering, the user has registered to MSC/VLR2, this moment, HLR cancelled this user's registration to MSC/VLR1, but because the MSC/VLR1 fault fails in time to delete this user data of users; After MSC/VLR1 recovers, MSC/VLR1 has recovered the user data before the fault according to backup, if this user has roamed into the scope that MSC/VLR1 covers this moment again, after MSC/VLR1 receives the solicited message that the user sends, MSC/VLR1 finds existing this user's data, just do not need to register to HLR, thereby cause the user data among the MSC/VLR2 also in time not deleted, and this user's register information that writes down among the HLR still is MSC/VLR2, and in fact this user in the scope that MSC/VLR1 covers, if this moment, this user did called, HLR can route calls to MSC/VLR2, and can not be routed to MSC/VLR1, so will cause can't this called subscriber of paging.When if networking mode is the MSC pond, then this problem is more outstanding.
So in the prior art, when VLR loses user data, also do not have a kind of method of calling called subscriber, can under the situation that solves problem that the channel of eating dishes without rice or wine impacted, realize paging simply and effectively to the called subscriber.
Summary of the invention

Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
The core concept of the embodiment of the invention is: after HLR receives called location information request, the called subscriber's of HLR record location area information is sent to the MSC/VLR of visit, and the called subscriber's that the MSC/VLR of visit sends according to HLR location area information is to this called subscriber's distributing paging.
Wherein, described HLR can be after MSC/VLR reports HLR with user's location area information, and user's location area information is carried out record.
At first, the called system of realization user that the embodiment of the invention provided is described.As shown in Figure 1, this system mainly comprises: the MSC/VLR 100 of visit and HLR 110.
The MSC/VLR 100 of visit reports HLR 110 with user's location area information; The called subscriber's who sends according to HLR110 location area information is to called subscriber's distributing paging.
In addition, receive called location information request after, HLR 110 can send to location area information originating MS C or Gateway MSC earlier, originating MS C or Gateway MSC send to location area information by the relaying signaling MSC/VLR 110 of visit again.Wherein, described originating MS C is used for sending called location information request to HLR when the call request of receiving the called subscriber, after receiving response, establishes a call to the MSC/VLR of visit; Gateway MSC is identical with originating MS C function, and just Gateway MSC is in the junction with network.
Wherein, when MSC/VLR reports HLR with user's location area information, if there is not called subscriber's user data among the MSC/VLR of visit, can be by sending position register request to HLR; If existing this called subscriber's user data among the MSC/VLR of visit can be realized by initiating position updating request to HLR.So, as shown in Figure 2, comprise among the MSC/VLR 100 of described visit: judge module 101, with Service Processing Module 102, and memory module 103.
Wherein, the location area information that comprises the called subscriber in described position register request and the position updating request.
Described location area information can be a direct position district information, also can be indirect location area information.Wherein, direct position district information is that the user is directly carried out the needed location area information of paging, and positional information is that the direct position information via transforms the cell that obtains indirectly, as MSC identification code (MSCID) or user area identification code.Location area information and direct position district information have mapping relations in MSC/VLR indirectly.
The MSC/VLR 100 of described visit can be before the called subscriber's who sends according to HLR 110 location area information be to called subscriber's distributing paging, judge the location area information that whether has had the called subscriber among the MSC/VLR that visits, if, then use existing location area information among the MSC/VLR, if not, then use the called subscriber's that HLR sends location area information.
Described judge module 101 and Service Processing Module 102 also are used for:
Judge module 101: the called subscriber's that reception HLR 110 sends location area information, judge whether have this user data of users in the memory module 103, if send trigger notice to Service Processing Module 102; If not, send the called subscriber's that HLR 110 send location area information to Service Processing Module 102;
If the location area information that is recorded among the HLR is indirect location area information, then the user does called, among the MSC/VLR of visit during user data of no use, VLR needs the positional information that HLR sends is converted to direct position district information before distributing paging, at this moment, judge module 101 further comprises: modular converter 104.
Below the called method of realization user that the embodiment of the invention provided is described.As shown in Figure 3, this method mainly may further comprise the steps:
Step 301:MSC/VLR reports HLR with user's location area information and carries out record.
MSC/VLR can more newly arrive and finishes reporting of customer location district information by initiate location registers or position to HLR in this step.
Before this step, may further include: receive user's request message as MSC/VLR after, judge whether this user's data is arranged among the MSC/VLR, if then MSC/VLR initiates the position renewal to HLR; If not, then MSC/VLR initiates location registers to HLR.
Wherein, described MSC/VLR initiates the position to HLR and upgrades and can realize by sending position register request to HLR, has wherein comprised user's location area information in the position register request.Its process as shown in Figure 4.May further comprise the steps:
Step 401:MSC/VLR receives the request message that the user sends.
As user visiting MSC/VLR, perhaps use certain business, perhaps initiate caller, when perhaps sending called paging response etc., can send this user's request message to the MSC/VLR of visit.Described user's request message can be a position register request message, the business request information that starts, page response request message or other request message.The location area information that has comprised this user in this solicited message.
Step 402: judge whether this user data of users has been arranged among the MSC/VLR, if not, execution in step 4.3a; If, execution in step 4.3b.
Step 4.3a:MSC/VLR sends position register request to HLR.
Comprise customer location district information in the described position register request.
After the step 4.4a:HLR recording user location area information, send the location registers response to MSC/VLR; Process ends.
Step 4.3b:MSC/VLR sends position updating request to HLR.
Comprised in the described position updating request and be used for location area information.This position updating request can be an information that increases newly, also can be the transformation of existing position register request, for example increases cell and become position register request in existing position register request.
After the step 4.4b:HLR recording user location area information, send the position to MSC/VLR and upgrade response.
In this step, it is not necessary sending position renewal response to MSC/VLR, can not have yet.
In addition, the user's who comprises in position register request or position updating request location area information can be a direct position district information, also can be indirect location area information.Wherein, direct position district information is that the user is directly carried out the needed location area information of paging, and positional information is that the direct position information via transforms the cell that obtains indirectly, as MSCID.Location area information and direct position district information have mapping relations in MSC/VLR indirectly.Example is as shown in table 1.
| The lane place | MSCID | Remarks |
| 0001 | 640501 | Local network 1 |
| 0002 | 640502 | Local network 2 |
| 0003 | 640502 | Local network 3 |
Table 1
MSCID is that 640502 lane place just is the lane place 0003 of the lane place 0002 of local network 2 and local network 3.
When MSC/VLR sends position updating request, can use existing location registers flow process, still, signaling traffic is bigger when using existing location registers flow process, and is bigger to the influence of network level system.
After step 302:HLR receives called location information request, called subscriber's location area information is sent to the MSC/VLR of visit.
The user does when called, and HLR can receive and start or called location information request that Gateway MSC sends that HLR sends called route requests to the MSC/VLR of visit then.Comprised the location area information that is recorded in the called subscriber among the HLR in the wherein said called route requests.
In addition, the called subscriber's who writes down among the HLR location area information can send to earlier and start or Gateway MSC, then by starting or Gateway MSC sends to the MSC/VLR of visit when set up calling out by the relaying signaling again.
Step 303: the called subscriber's that the MSC/VLR of visit sends according to HLR location area information is to this called subscriber's distributing paging.
Before this step, may further include, judge the location area information whether called subscriber is arranged among the MSC/VLR that visits, if, the just preferential location area information of using the called subscriber who preserves among the MSC/VLR; If not, then use the called subscriber's that HLR sends location area information.
When the called subscriber's who uses HLR to send location area information, if when the called subscriber's that HLR sends location area information is direct position district information, then MSC/VLR directly utilizes this location area information to called subscriber's distributing paging; When if the called subscriber's that HLR sends location area information is indirect location area information, then MSC/VLR needs and should indirect location area information be converted to direct position district information according to corresponding mapping relations, and then to called subscriber's distributing paging.
Be example still with table 1, when if the indirect location area information of the called subscriber that HLR sends is MSCID640502, MSC/VLR need be converted to location area information 0002 and 0003 with MSCID 640502, and MSC/VLR is laying respectively at 0002 and 0,003 two position range distributing paging of local network 2 and local network 3 so.
The detailed process of described step 302 and step 303 as shown in Figure 5.Mainly may further comprise the steps:
Step 501:HLR sends to MSC/VLR with called subscriber's location area information.
Step 502: judge the location area information whether this user is arranged among the MSC/VLR, if, execution in step 503; If not, execution in step 504.
The called subscriber's that step 503:MSC/VLR preserves according to self location area information is to this user's distributing paging, process ends.
Step 504: whether the location area information of judging this user that HLR sends is direct position district information, if, execution in step 505; If not, execution in step 506.
The called subscriber's that step 505:MSC/VLR sends according to HLR direct position district information is to this user's distributing paging, process ends.
After step 506:MSC/VLR is converted to direct position district information with indirect location area information, according to direct position district information to this user's distributing paging.
In addition, MSC/VLR can be to called subscriber's distributing paging after receiving the called route requests that HLR sends, also can receive start or the setup requests of Gateway MSC after the called subscriber is initiated paging.
Fig. 6 is the called call establishment figure of user.Call establishment when as shown in Figure 6, the user is called mainly may further comprise the steps:
Step 6.1: the user does when called, starts or Gateway MSC can be received call request to this user.
Step 6.2: start or Gateway MSC sends called location information request to HLR.
Step 6.3:HLR sends called route requests to MSC/VLR.
Described calledly have the road request to comprise the location area information that is recorded in this user among the HLR.
Step 502 sends the paging request to step 506 to the user in the step 6.a:MSC/VLR execution graph 5.
Step 6.4:MSC/VLR returns called route requests response to HLR.
Step 6.5:HLR is to starting or Gateway MSC sends the response of called location information request.
Step 6.6: start or Gateway MSC with call setup to MSC/VLR.
In said process, execution in step 6.a not, and at step 6.6 back execution in step 6.a.
In addition, when the execution in step 6.a of step 6.6 back, in above-mentioned steps 6.3, HLR can not comprise the location area information that is recorded in this user among the HLR in the called route requests that MSC/VLR sends, and in step 6.5, HLR comprises this user's location area information in the called location information request that starts or Gateway MSC sends responds, then in step 6.6, start or Gateway MSC when set up calling out, this user's location area information is sent to MSC/VLR, then execution in step 6.a.
In the said method, the MSC/VLR of described visit can be independently MSC/VLR, can be the alternate device of MSC/VLR of visit, or the MSC/VLR pond of visit.
By as can be seen above, the user does the location area information that MSC/VLR when called can send according to HLR, not needing to increase in addition alternate device backs up user profile, and after MSC/VLR receives that the user asks, user's location area information is reported HLR carry out record, avoid " dual-active " of the prior art and " live " phenomenon more effectively, solved the problem that the channel of eating dishes without rice or wine is impacted more simply and effectively.
Further, the method and system that the embodiment of the invention provided, can also be further used for MSC pond or active and standby MSC or the MSC that helps each other etc. has the solution of a plurality of MSC/VLR, if the MSC/VLR1 that is using breaks down, then take over and finish business function by the MSC/VLR2 that backs up, the user data that may not have Anchor MSC/VLR1 among the MSC/VLR2 of backup, the MSC/VLR2 of backup this moment just can use the called subscriber's who sends among the HLR data, to called subscriber's distributing paging.
