Description
Technical field
The present invention relates to telecommunication technology, be specifically related to be used for method, network element, network infrastructure and the communication system of updating of terminal position.
Background technology
Cellular radio Communication system is divided into access network and core network usually.Access network among the GSM comprises base station (BTS) and Control Node such as base station controller (BSC), and core network comprises core network node (CNN), for example mobile switching centre (MSC), Visited Location Registor (VLR), attaching position register (HLR), and if system comprise that GPRS (GPRS) also comprises GPRS Support Node (GSN).The example of GSN is Serving GPRS Support Node (SGSN).
Cellular radio Communication system of future generation, promptly the third generation (3G) is called IMT 2000 by International Telecommunication Union, and comprises universal mobile telecommunications system (UMTS).Access network among the UMTS comprises base station (Node B) and Control Node such as radio network controller (RNC), and core network comprises the node (as mentioned above) with the gsm system same type.
Each Control Node in access network (BSC or RNC) specifies the MSC service to provide support by one, and each MSC in the core network is provided support by known appointment VLR service in GSM and UMTS system.This means that each Control Node communicates by letter with a special-purpose MSC usually, the specific geographical area of this special use MSC service cellular system is the MSC service area territory, and means that each MSC communicates by letter with a special-purpose VLR usually.When mobile radio station when the cellular system request is served, its can be connected to the MSC in current MSC service area territory by a Control Node.Using the mobile subscriber's of mobile radio station user profile to be stored among the VLR of service MSC, promptly the mobile subscriber is registered among this VLR.Common realization is that VLR and MSC are combined into MSC/VLR, this means that the mobile subscriber is registered among the MSC/VLR.Because the mobile subscriber is using the fact of mobile radio station, says also that usually mobile radio station is registered among the MSC/VLR.
When the mode that with needs mobile subscriber's's (mobile radio station, or terminal) registration is moved to the 2nd MSC/VLR from a MSC/VLR when mobile radio station in cellular radio Communication system moves, be called " position renewal ".The one MSC/VLR is called old or previous MSC/VLR, and the 2nd MSC/VLR is called new MSC/VLR.Correspondingly, if mobile radio station is supported GPRS, just mobile subscriber's registration need be moved to another SGSN from a SGSN.This is similar to the roaming between MSC/VLR.The one SGSN is called old or previous SGSN, and the 2nd SGSN is called new SGSN.
Usually, the position of mobile radio station is upgraded and carried out as follows: at first, new MSC/VLR (or new SGSN) sends location update message to HLR, and for example MAP-UpdateLocation or MAP-UpdateGPRSLocation message are given HLR with update notification; HLR sends deletion message, for example MAP-CancelLocation message to old MSC/VLR (or old SGSN) then; Old MSC/VLR (or old SGSN) deletes user's data after receiving deletion message.(referring to 3GPP TS 23.012 and 3GPP TS 23.060)
In nearest practice, a physical network element (for example MSC/VLR) has a plurality of addresses virtually.In mobile subscriber business activity (transaction), network element must send to its address other network element.Network element depends on to the address that the external world shows where the user is physically located in.When for example two when being substituted by the larger capacity network element that can serve two zones (A+B) than low capacity network element (service zones of different A and B), this is suitable for, but, external network units is not recognized this variation, because based on the address that receives in mobile subscriber business activity (transaction), they are seen remains two different network element.
Because so a plurality of virtual addresses are arranged, sometimes,, the user upgrades even carrying out the position in the same physical network element, and VLR/SGSN also must send to HLR with location update message, to upgrade the information among the HLR.
This means needs to handle new position updating type.Position reproducting periods at (or between the virtual SGSN in SGSN inside) between the virtual VLR of VLR inside, must will new virtual VLR/ virtual MSC or virtual SGSN address notification to HLR, that is to say that under this accompanying information VLR/MSC or SGSN also must send to HLR with location update message.
Problem is, when VLR/MSC or SGSN send to HLR with location update message, wherein VLR, MSC or SGSN address with in HLR address stored different, HLR will think that it is that position between the VLR or between the SGSN is upgraded, therefore HLR will send deletion message to old VLR/MSC or SGSN address, and in fact it point to same physics VLR/MSC or SGSN.Be used for all virtual VLR/MSC or SGSN (as in most of the cases desired) if physics VLR/MSC or SGSN have single database, deletion message will attempt to remove the user data that is being upgraded by the position refresh routine.This causes VLR/MSC or the unpredictable influence of SGSN, should be avoided its generation.

Embodiment
Below just in conjunction with the accompanying drawings each embodiment of the present invention is described in detail.
Fig. 1 shows the flow chart that is used for the method for updating of terminal position according to an embodiment of the invention.Fig. 2 shows the block diagram of communication system, implements to be used for according to an embodiment of the invention the method for updating of terminal position therein.
As shown in Figure 2, communication system comprises network infrastructure 200 and at least one terminal T1.Network infrastructure 200 comprises VLR/SGSN 1, the VLR/SGSN 2 with virtual address 2-1 and 2-2, VLR/SGSN 3 and the HLR 201 with virtual address 1-1 and 1-2.As mentioned above, upgrade the position that is similar between two SGSN in the position between two VLR and upgrade, therefore they are generically and collectively referred to as " first network element " in the present invention.In addition, in fact MSC and VLR can combine, and can have more multiple terminals and/or more VLR/SGSN in communication system.In addition, VLR/ SGSN 1 and 2 can have more virtual addresses respectively.
When terminal T1 moves to another VLR/SGSN from a VLR/SGSN, for example when VLR/SGSN 1 moves to VLR/SGSN 3, perhaps when terminal T1 when the virtual address of same VLR/SGSN moves to another virtual address, need carry out the position and upgrade, with the user profile among notice HLR 201 changes and/or the renewal VLR/SGSN.Yet, between two virtual addresses at a VLR/SGSN, for example between the virtual address 1-1 of VLR/SGSN 1 and 1-2, carry out the position when upgrading, as among Fig. 2 shown in dashed lines L1 and the L2, HLR 201 will think that this location update message is the position renewal between the VLR or between the SGSN, and therefore, it will send deletion message (cancallation message) to old VLR or SGSN address, in fact it point to same physics VLR or SGSN, and promptly VLR/SGSN 1.Be used for all virtual VLR or SGSN (as in most of the cases desired) if VLR/SGSN 1 has single database, deletion message will attempt to remove the user data among the VLR/SGSN 1, and this may cause communication system failure.
The flow chart of Fig. 1 shows the method that is used for updating of terminal position according to an embodiment of the invention that is provided for addressing the above problem.
As shown in Figure 1, at first in step 101, when terminal T1 moved to the new virtual address of a new VLR/SGSN or a physics VLR/SGSN, the position that VLR/SGSN (new VLR/SGSN and/or old VLR/SGSN) can sense terminals was upgraded.For example, it can be carried out like this, by coming the routing region updating request (routing area update request) and the program (shown in 3GPP TS 23.060) afterwards thereof of adhering to request (attach request) or coming self terminal of self terminal; It also can be carried out like this, adheres to message and program afterwards (shown in 3GPP TS 23.012) thereof by position updating request (location updatingrequest) or the IMSI that comes self terminal.The present invention upgrades without any restriction the position of sense terminals.
In step 105, whether the position of judging terminal is upgraded between two virtual addresses of consolidated network unit (VLR/SGSN).For example, in the system of Fig. 2, if terminal location is updated to virtual address 1-2 (L2) from the virtual address 1-1 (L1) of VLR/SGSN1, network element (VLR/SGSN1) can judge as follows that this is that the position of VLR/SGSN inside is upgraded.VLR/SGSN checks the old band of position (old location area) that is sent by terminal in position updating request.If previous location area (the old band of position) can find in the tabulation of the band of position of oneself, this is that the position of VLR/SGSN inside is upgraded so.When VLR/SGSN judges is the position of VLR/SGSN inside when upgrading, and it also checks the virtual VLR/SGSN the matching addresses whether old virtual VLR/SGSN address of storing is associated with user's new location area in user data.If two address differences, then this is that position between the virtual VLR/SGSN of VLR/SGSN inside is upgraded, and must upgrade HLR.
Similarly, if terminal is updated to the virtual address 2-1 (L3) of VLR/SGSN 2 from virtual address 1-1 (L1) position of VLR/SGSN 1, network element (VLR/SGSN 2) can judge that this is the position renewal between the VLR/SGSN.
If be judged as in step 105 be, method proceeds to step 110, and inhibition delete flag that wherein will the in-position updating message is set at ON; Otherwise method proceeds to step 115, wherein will suppress delete flag and be set at OFF or do not set mark.
Then, in step 120, network element (for example VLR/SGSN 1) will have or not have the location update message that suppresses delete flag and send to HLR (for example HLR 201).Suppress delete flag,, show deletion message whether unnecessary (unnecessary) if comprise.If do not comprise the inhibition delete flag, mean that then deletion is necessary.Be an example of location update message below.
| UpdateLocationArg::＝SEQUENCE{ imsi IMSI， msc-Number[1]ISDN-AddressString， vlr-Number ISDN-AddressString， lmsi [10]LMSI?OPTIONAL， extensionContainer ExtensionContainer OPTIONAL， ...， vlr-Capability[6]VLR-Capability OPTIONAL， informPreviousNetworkEntity [11]NULL OPTIONAL， cs-LCS-NotSupportedByUE [12]NULL OPTIONAL， v-gmlc-Address [2]GSN-Address OPTIONAL， suppressCancelLocation [x]NULL OPTIONAL} |
Be appreciated that the present invention is not limited to above-mentioned message format, the present invention can use necessary information upgrades and delete the necessity of message with the position that shows terminal the message that has of any form.
In step 125, HLR is based on the location update message from VLR/SGSN, be updated in wherein storage about terminal information.
In step 130, HLR determines whether the inhibition delete flag in location update message comprises and is ON.If definite inhibition delete flag comprises and is ON that HLR skips deletion message (step 135); Otherwise HLR will delete message and send to old VLR/SGSN, and user data (step 140) is removed in indication.After receiving deletion message, old VLR/SGSN deletion corresponding user data (step 145) therein.
Then, in step 150, method proceeds to the down-stream that the completing place is upgraded, and it comprises user data is downloaded to new VLR/SGSN from HLR.The present invention to described down-stream without any restriction.
From foregoing description as can be seen, the method that is used for updating of terminal position according to this embodiment, whether unnecessary because the VLR/SGSN that the detection position is upgraded is by setting in location update message if suppressing delete flag notice HLR deletion message, can avoid having undesirable deletion of the user data among the VLR/SGSN of a plurality of virtual addresses.
Fig. 3 shows the flow chart of the method that is used for updating of terminal position according to another embodiment of the invention.
As shown in Figure 3, at first in step 301, upgrade by the position of VLR/SGSN sense terminals.Be similar to previous embodiment, for example, when terminal T1 moved to the new virtual address of new VLR/SGSN or physics VLR/SGSN, the position that this VLR/SGSN (new VLR/SGSN and/or old VLR/SGSN) can sense terminals was upgraded.
Then, in step 305, this VLR/SGSN (new VLR/SGSN or the VLR/SGSN with new actual address of the position of VLR/SGSN inside upgrading) sends to HLR (for example HLR 201) with location update message, and notice HLR upgrades this position.Here, location update message can be conventional form, as described in 3GPP TS 29.002, perhaps can be any other form that can notify the position renewal of terminal.
In step 310, HLR position-based updating message is updated in the information about this terminal (user) in its database.The present invention to the order of the program among the HLR without any restriction.
In step 320, the deletion message (cancallation message) that HLR will have destination address sends to old VLR/SGSN.This destination address comprises the target of deletion, and it is the address (or old virtual address) by the old VLR/SGSN of HLR maintenance.Be a form example of the deletion message that can use in the present embodiment below.
| CancelLocationArg::＝[3]SEQUENCE?{ identity Identity， cancellationType CancellationType OPTIONAL， extensionContainer ExtensionContainer OPTIONAL，...， targetNetworkEntityAddress ISDN-AddressString OPTIONAL} |
Be appreciated that the present invention is not limited to this message format, the present invention can use any message that can show the form of the destination address of deleting message.
Then, in step 325, when VLR/SGSN receives deletion during message, its judges that the destination address in deletion message is whether different with the actual virtual network of the terminal that is kept by VLR/SGSN-adhere to address (actual VLR/SGSN address).Here, the network of terminal-adhere to address is meant that terminal adheres to the address of the network element that is used to the service of obtaining (or virtual address), for example address of VLR, SGSN etc. etc.
For example, if terminal T1 moves to virtual address 1-2 (L2) from the virtual address 1-1 (L1) of VLR/SGSN 1, VLR/SGSN 1 promptly is that new VLR/SGSN also is old VLR/SGSN, and the actual virtual network of the terminal in VLR/SGSN 1-adhere to address (actual VLR/SGSN address) is virtual address 1-2, and it is virtual network-the adhere to address of the terminal that up to the present kept by VLR/SGSN 1.
In addition, if terminal T1 moves to the virtual address 2-1 (L3) of VLR/SGSN 2 from the virtual address 1-1 (L1) of VLR/SGSN 1, VLR/SGSN 1 is old VLR/SGSN, VLR/SGSN 2 is new VLR/SGSN, and the actual virtual network of the terminal in VLR/SGSN 1-adhere to the address is virtual address 1-1, and it is the virtual address of the terminal that up to the present kept by old VLR/SGSN 1.
If be judged as not in step 325, method proceeds to step 330, wherein old VLR/SGSN deletion user data therein; Otherwise VLR/SGSN skips the deletion (step 335) of user data.
Then, in step 340, method proceeds to the down-stream that the completing place is upgraded, and it for example comprises user data is downloaded to new VLR/SGSN from HLR.The present invention to described down-stream without any restriction.
From as can be seen according to the method foregoing description that is used for updating of terminal position of present embodiment, because HLR shows the target location in deletion message, and VLR/SGSN judges that after receiving deletion message the destination address of deleting in the message is whether different with the actual virtual network of terminal-adhere to the address, can avoid having undesirable deletion of the user data among the VLR/SGSN of a plurality of virtual addresses.
In addition, according to another embodiment, method shown in Figure 1 can combine with method shown in Figure 3.That is to say, the step 140 in Fig. 1, HLR also can comprise the destination address (by the old VLR/SGSN address of HLR maintenance) of deletion in deletion message, and sends it to old VLR/SGSN; Then, in step 145, VLR/SGSN judges that after receiving deletion message the destination address in deletion message is whether different with the actual virtual network of terminal-adhere to the address, and have only ought two addresses mutually to seasonable deletion user data.
Similarly, the step 305 in Fig. 3, VLR/SGSN can judge that also whether the position of terminal upgrade between two virtual addresses of same VLR/SGSN, and shows in location update message whether deletion is unnecessary; Then, in step 320, only delete in case of necessity when the location update message indication, HLR just sends deletion message.
Under same inventive concept, Fig. 4 shows the block diagram of network element according to an embodiment of the invention, and it can be realized as VLR/SGSN in the communication system of Fig. 2.
As shown in Figure 4, network element 400 comprises: checkout gear 401, and the position that is used for sense terminals is upgraded; Whether judgment means 402, the position that is used to judge described terminal are upgraded between two virtual addresses of network element; And the first message dispensing device 403, be used for location update message is sent to HLR.Similar with previous embodiment, in the present embodiment, the location update message that is sent by the first message dispensing device 403 shows that the position of described terminal is upgraded and whether deletion message is unnecessary, and when being judged that by described judgment means 402 position of described terminal is updated between two virtual addresses of network element, described location update message shows that described deletion message is unnecessary.
In addition, network element 400 can also comprise: second message receiving apparatus 404 is used to receive the described deletion message from HLR; And delete device 405, be used for according to the described deletion message that receives delete described network element about described terminal information
Fig. 5 shows the block diagram of network element according to an embodiment of the invention, and it can be realized as HLR in the communication system of Fig. 2.
As shown in Figure 5, network element 500 comprises: first message receiving apparatus 501, be used to receive location update message from VLR/SGSN, and described location update message shows additionally whether deletion message is unnecessary; Updating device 502 is used for being updated in this network element canned data according to described location update message; And the second message dispensing device 503, show deletion message necessity if be used for this location update message, described deletion message is sent to VLR/SGSN.
From foregoing description as can be seen, utilize network element 400 as VLR/SGSN, network element 500 is as HLR, whether unnecessary because the VLR/SGSN that the detection position is upgraded is by setting in location update message if suppressing delete flag notice HLR deletion message, can avoid having undesirable deletion of the user data among the VLR/SGSN of a plurality of virtual addresses.
According to the distortion of present embodiment, the dispensing device 503 of network element 500 can be configured to further show the destination address of deletion in deletion message; And the delete device 405 of network element 400 only can be configured to when the destination address of described deletion not with the actual virtual network of described terminal-adhere to the address not simultaneously, deletion is about described terminal information.
