Description
Technical field
The present invention relates to a kind of communication technology, relate in particular to a kind of communication means and system, reach mobile switching centre.
Background technology
In actual applications, certain user needs two terminals, and these two terminals have identical SIM (Subscriber Identity Module; User identification module) card promptly has identical IMSI (International Mobile Subscriber Identity, IMSI International Mobile Subscriber Identity).As, the user has a mobile phone and a Vehicle mounted station, as this user not onboard the time, uses mobile phone and other user terminal to communicate; As this user onboard the time, use Vehicle mounted station and other user terminal to communicate.Like this, use jack per station to compare, have following benefit with each terminal: for same user, the collision problem that is produced in the time of at first can not causing two terminals of jack per station to communicate by letter simultaneously; Secondly, when with other telex network, can make the user utilize the terminal of most convenient to communicate, as, as this user onboard the time, use Vehicle mounted station and other terminal to communicate, other situation, use mobile phone and miscellaneous equipment communicate; The 3rd, can use same account to charge, promptly make things convenient for network billing, also can make things convenient for subscriber payment.
Yet the inventor finds in the invention process, in the existing communication system, only allows the terminal of a unique IMSI, and IMSI is globally unique IMSI International Mobile Subscriber Identity, and it writes in the SIM card usually.Because two terminals are used identical SIM card in communication system, promptly use identical IMSI, be that communication system protocol institute is unallowed, thereby make present system can't satisfy this demand.
In existing systems, why do not allow two terminals to use identical IMSI, reason is, all be to be the data that sign is distinguished user storage with IMSI in the time of storage of subscriber data, these data comprise user's business data signed, and the required information and the data of some system handles flow processs of interim storage in the customer service process.If the user of two identical IMSI signs in to system simultaneously, what can cause that two users' service access flow process or position upgrade that flow processing relied on is the user contracting data and the conflict of user's flow process temporary information of unique sign index with user ID.
As shown in Figure 1, suppose to have IMEI (the International Mobile EquipmentIdentity of two terminal equipments, International Mobile Station Equipment Identification) is respectively IMEI1 and IMEI2, but the IMSI in these two terminal equipments is identical (for example SIM card is for duplicating fully), two terminal equipments can independently be initiated business and/or position renewal, but operation flow and/or position are more done sign to required user data access with IMSI in the new technological process and are read and write, therefore in data storage procedure, what in fact two terminals were used is same user data of users, as use among the VLR (Visited Location Registor, Visited Location Registor) and the IMSI1 corresponding user data.When more new technological process is stored or is read same user data of users operation flow of initiating when two terminals and/or position, will cause the change of some ephemeral datas in these two flow processing processes unpredictable, influencing each other will appear in handling process, cause handling process unusual, under the serious situation even can cause system in case of system halt.

Embodiment one
Present embodiment provides a kind of communication means, and this method comprises: obtain IMSI and IMEI; Judge whether the IMSI among the VLR is identical with the IMSI and the IMEI of acquisition with IMEI,, then allow follow-up flow process if identical, otherwise, follow-up flow process refused.Be example with GSM/UMTS (Global System for Mobilecommunication/Universal Mobile Telecommunication System, global mobile communication system/general mobile communication system) system below.IMSI, IMEI are combined the problem that solution clashes because of IMSI is identical.Below with service access flow process or position more new technological process be the communication means of example explanation present embodiment.Here said position is upgraded, and comprises switching on and shutting down, general position renewal, various situations such as periodic location update.Here said service access comprises that miscellaneous services such as voice, data, short message insert.
In order to distinguish jack per line (IMSI) different terminals, can utilize the IMEI of user data in the VLR database to distinguish the different terminals of jack per line.The method of upgrading the IMEI of current terminal among the VLR/HLR (Home Location Register home location register) has following situation:
One, by the signatory IMEI that has terminal among the VLR/HLR that upgrades.In a plurality of terminals of jack per line, a certain moment has only the terminal of a signatory IMEI correspondence.This subscription data can directly be revised by HLR, also can pass through USSD (Unstructured Supplementary Service Data by this signatory terminal, unstructured supplementary service data) revise CAMEL-Subscription-Information, the text formatting of going here and there as USSD is: the method for service code+password+IMEI.Particularly, HLR judges at first whether password is correct after receiving the USSD string, if password is correct, just the IMEI of this IMSI association is refreshed the IMEI that is in the string, send then and insert subscriber data message to VLR, refresh the record among the VLR, amended signatory IMEI is inserted among the current VLR.After this CAMEL-Subscription-Information is modified, is about to signatory IMEI and is revised as non-signatory terminal, and other terminal modifications of jack per line is signatory terminal.After the signatory IMEI among the VLR revised, current terminal seemed to fall net immediately, but when the user inserted or the position is upgraded once more, the meeting display business inserted or failure is upgraded in the position.
Two, upgrade the IMEI that has this terminal among the VLR by the start and/or the shutdown of terminal, like this, start at first is linked into the terminal of MSC, has the IMEI of this terminal in VLR.When terminal closedown, can trigger IMSI detach (IMSI separation) flow process, in the IMSI separation process, the IMEI that writes down among the VLR is disposed.Do not shut down and the situation of direct power down for terminal,, also can dispose IMEI again through IMSI implicit detach week after date.This moment, the another one terminal of jack per line just can be landed network.If terminal is the situation of direct power down, want in time to allow the another one terminal land network, so just need the terminal start earlier shutdown again of this power down.
Because in GSM/UMTS standard handling process, all User Activities can be able to be summed up as two big classes: the position is new technological process and operation flow more, therefore, only introduces this two big class flow process below.When user terminal is linked into network MSC (Mobile Switching Center, mobile switching centre) time, MSC at first finds this user data of users according to IMSI in VLR, and then judge that the IMEI that whether has current terminal among the VLR/HLR decides this user whether to allow access network and carries out follow-up flow process, if exist, then allow to insert, otherwise do not allow to insert.Describe below according to whether existing IMEI to describe the communication means of present embodiment among the VLR/HLR:
For upgrade the situation that has the IMEI of terminal among the VLR/HLR by contracting.The position is more in new technological process or the service access flow process, the IMEI that gets terminal goes up, if the signatory IMEI that stores among the terminal IMEI that gets up and the VLR is identical, allow terminal to carry out follow-up activity, if the IMEI that stores IMEI that gets up from terminal and the VLR is inequality, then do not allow the terminal flow process to continue, the activity of terminal is refused.If user data of no use among the VLR, the position that then is initiated to HLR is upgraded, and judge that by HLR this position upgrades whether to be the position of current signatory subscriber equipment upgrade this moment, if, then allow this position to upgrade, otherwise, refuse this position and upgrade.VLR brings HLR IMEI, can use the message field of ADD (Automatic Device Detection-3GPP 29002-6f0) characteristic definition to bring HLR IMEI.Like this, only the signatory pairing terminal of IMEI can be carried out position renewal and service access on HLR, and Qian Yue terminal cannot not carried out position renewal and service access.
The co-location renewal that comes up for PS territory (packet domain) also is same treatment principle, can get the operation of IMEI equally, gets IMEI and upward handles according to top position renewal principle equally the back.
Fig. 2 has described position updating process, and as shown in Figure 2, position more new technological process is as follows.
Step 21, terminal send position updating request to mobile switching centre.
Step 22, mobile switching centre send location update request message to VLR.
Step 23, VLR return to mobile switching centre and obtain IMEI message.
Step 24, mobile switching centre send identity request message to terminal.
Step 25, terminal are returned identity response to mobile switching centre.
Step 26, mobile switching centre send to VLR and obtain IMEI message.
If step 27 VLR exists and current terminal corresponding user data, whether the IMEI that obtains in the IMEI message in the VLR determining step 26 is identical with the IMEI of this locality, and according to judged result the position is set and upgrades response message, if it is identical, then in the position renewal response message indicating positions being set upgrades successfully, otherwise, upgrade indicating positions renewal failure in the response message in the position.The IMEI that this position is upgraded in the flow process hypothesis acquisition IMEI message is different with local IMEI.
If, need arrive when obtaining this user data of users among the HLR, then carry out and the similar deterministic process of VLR at HLR because of there not being the ephemeral data of current terminal among the VLR.
Should be noted that MSC closes with VLR usually in the practical application is located at, and therefore, can think that also the deterministic process of step 26 is finished in MSC.
Step 28, VLR upgrade response message with the position and issue mobile switching centre.
After step 29, mobile switching centre receive position renewal response message, find the failure of position renewal response message Position Updating, send to terminal and refuse location update message.
