The corresponding relation that needs maintaining IMS I and IMEI among the present invention, and this corresponding relation can have two kinds of maintenance forms, and the corresponding relation of first kind of maintenance mode comprises: the IMSI tabulation that IMEI tabulation that IMSI is signatory and IMEI are signatory.Can comprise one or more IMEI during the signatory IMEI of IMSI tabulates, represent the signatory pairing equipment of the one or more IMEI of use that allows of certain IMSI; If IMEI tabulation for empty, then represents the signatory as yet any IMEI of IMSI that should the IMEI tabulation, this IMSI can use arbitrarily as yet the equipment of signatory IMSI.Similarly, can comprise one or more IMSI during the signatory IMSI of IMEI tabulates, represent the signatory one or more IMSI of use that allow of certain IMEI; If IMSI tabulation for empty, then represents the signatory as yet any IMSI of IMEI that should the IMSI tabulation, this IMEI can use arbitrarily as yet the IMSI of signatory IMEI.
At this first kind of corresponding relation, the mode of operation one of its inquiry and binding relationship verification is:
The IMSI tabulation that the IMEI of A, inquiry terminal is signatory, and the signatory IMEI tabulation of IMSI used of terminal, if the IMSI that exists terminal using in the IMSI tabulation, and have the IMEI of terminal in the IMEI tabulation, judge that then the verification of binding relationship is passed through;
If the IMSI that does not exist terminal using in the B IMSI tabulation, and/or do not have the IMEI of terminal in the IMEI tabulation, judge that then the verification of binding relationship is not passed through;
If the signatory IMSI tabulation of the IMEI of C terminal is for empty, and the signatory IMEI tabulation of the IMSI that using of terminal judges then that also for empty the verification of binding relationship is passed through;
If the signatory IMSI tabulation of the IMEI of D terminal is for empty, and the signatory IMEI tabulation of the IMSI that using of terminal judges then that for empty the verification of binding relationship is not passed through;
If the signatory IMEI tabulation of the IMSI that the E terminal is being used is sky, and the signatory IMSI tabulation of the IMEI of terminal be sky, judges that then the verification of binding relationship is not passed through.
The corresponding relation of second kind of maintenance mode comprises: the group id that group id that IMSI is signatory and IMEI are signatory.Be the signatory globally unique group id of IMSI and IMEI, what store in the corresponding relation is each IMSI and its signatory group id, and each IMEI and its signatory group id.
At this second kind of corresponding relation, the mode of operation two of its inquiry and binding relationship verification is:
The group id that IMEI contracted of a, inquiry terminal, and the group id that IMSI contracted that using of terminal, and judge whether the group id of being inquired about is consistent, if consistent, judges that then the verification of binding relationship is passed through; If inconsistent, judge that then the verification of binding relationship is not passed through;
If all not signatory group id of the IMSI that the IMEI of b terminal and terminal are being used judges that then the verification of binding relationship is passed through;
If the IMSI that c is using for the IMEI and the terminal of terminal has only one of them not signatory group id, judge that then the verification of binding relationship is not passed through.
It is to be noted, the present invention can write down its signatory IMEI tabulation for each signatory IMSI in the database of HSS, and apply for the IMEI of signatory binding IMSI for each and write down its signatory IMSI tabulation, promptly adopt above-mentioned first kind of maintenance mode, the corresponding relation of storage and maintaining IMS I and IMEI by HSS.Certainly, also can adopt above-mentioned first kind of maintenance mode, the corresponding relation of storage and maintaining IMS I and IMEI by EIR.So corresponding, the mode of operation one of above-mentioned inquiry and binding relationship verification can be carried out by HSS or EIR.In addition, because the IMEI of terminal and the IMSI that terminal is being used, collected by MME at first, therefore the mode of operation one of above-mentioned inquiry and binding relationship verification also can be carried out by MME, just needs HSS that the corresponding relation inquiry service of IMSI and IMEI is provided for MME.
In the database of HSS, also can adopt second kind of maintenance mode, the group id that group id that storage and maintaining IMS I are signatory and IMEI are signatory.So corresponding, the mode of operation two of above-mentioned inquiry and binding relationship verification can be carried out by HSS.In addition, because the IMEI of terminal and the IMSI that terminal is being used are collected by MME at first, therefore the mode of operation two of above-mentioned inquiry and binding relationship verification also can be carried out by MME, just needs HSS that the inquiry service of group id is provided for MME.
Further elaborate below in conjunction with the method for calibration of specific embodiment above-mentioned IMSI and IMEI binding relationship.
In embodiments of the invention one, according to method shown in Figure 2, the binding relationship of verification IMEI and IMSI in MME judges whether to allow to insert, and finally finishes the process that EPS adheres to, and as shown in Figure 3, mainly may further comprise the steps:
Step 301, terminal are initiated initially to adhere to, and send Attach Request message to the base station of evolution (eNB, evolved NodeB).Comprise terminal use's IMSI or old global unique temporary identity (GUTI, Global Unique Temporary Identity) in this message.
Step 302, eNB selects a MME or selects a MME according to network topology according to the GUTI in the Attach Request message, and this Attach Request message is sent to the new MME of selection.
Step 303, if that carry in the Attach Request message is old GUTI, and current new MME is not the MME of terminal when adhering to last time, then new MME need obtain identity informations such as IMSI, untapped authentication vector, key from old MME/SGSN, and according to the identity information that obtains Attach Request message is carried out completeness check.
Step 304, if terminal does not all have record in new MME, old MME/SGSN, then new MME obtains IMSI to terminal.Be that new MME sends identification request to terminal, terminal sends to IMSI new MME in identification response.
Step 305; if terminal does not all have contextual information in new MME, old MME/SGSN; if perhaps the Attach Request message in the step 301 does not have integrity protection, if again or adhere to request by completeness check, then new MME must send the authorization data request message to HSS.The IMSI that comprises the terminal use in this authorization data request message.
Step 306, HSS at first searches the pairing user contracting data of IMSI in the authorization data request message, is put on the blacklist if search less than any signatory or IMSI, and then HSS returns the authorization data response and carries suitable error reason to new MME; If find the user contracting data corresponding with IMSI, then HSS returns the authorization data response message to new MME, comprises authentication vector in this response message.
Step 307 if carried out step 305 and 306, just must be carried out the legitimacy of authorizing procedure with verification terminal IMSI between so new MME and the terminal, and carry out the safe mode flow process to enable safe connection.
Step 308, under the scene of initially adhering to, new MME is to terminal transmitting apparatus identity request message, the IMEI of acquisition request terminal; Terminal is to new MME Returning equipment identity response message, to inform the IMEI of new this terminal of MME.Set up because safety connects, so this identity request message, identity response message are encrypted transmission.
Step 309, if network design EIR, then MME can select the legitimacy to the IMEI of EIR inquiry terminal.
Step 310, new MME sends location update request message to HSS, comprises the IMSI and the IMEI of terminal in this request message.
Step 311, HSS upgrades response message to new MME home position.
It is pointed out that if adopt aforesaid operations mode one user contracting data that needs to comprise terminal in the response message, user's the legal IMEI tabulation that IMSI contracted, the legal IMSI tabulation that IMEI contracted of terminal are upgraded in this position so; If adopt aforesaid operations mode two, the group id of IMEI correspondence of group id, the terminal of the user contracting data that needs to comprise terminal in response message, user's IMSI correspondence is upgraded in this position so.
Step 312, new MME upgrades entrained information in the response message according to the position, and the IMEI of terminal and the IMSI that is using are carried out the binding relationship verification.
If the user contracting data that comprises terminal in the response message, user's the legal IMEI tabulation that IMSI contracted, the legal IMSI tabulation that IMEI contracted of terminal are upgraded in the position that HSS returns, so new MME need carry out the binding relationship verification according to the IMSI that the IMEI and the terminal of a pair of terminal of aforesaid operations mode are being used.If the group id of IMEI correspondence of group id, the terminal of the user contracting data that comprises terminal in the response message, user's IMSI correspondence is upgraded in the position that HSS returns, so new MME need carry out the binding relationship verification according to the IMSI that the IMEI and the terminal of two pairs of terminals of aforesaid operations mode are being used.
Step 313 if verification is passed through, then continues to carry out the subsequent process of attachment flow.
Step 314, if verification is not passed through, then new MME refuses the request of adhering to of terminal, and returns suitable cause value to terminal.
Need to prove, for aforesaid operations mode one, according to the needs of operator, if in the record of HSS database, search the IMSI that is using less than the IMEI or the terminal of terminal, then can select to refuse terminal and insert, the tabulation that also can be used as IMEI or IMSI correspondence is that sky is handled; For aforesaid operations mode two, if in the record of HSS database, search the IMSI that is using less than the IMEI or the terminal of terminal, then can select to refuse terminal and insert, can be used as does not have the situation of group id to handle yet.
In addition, in order to satisfy the access authentication demand of different stage in the practical application, at aforesaid operations mode one, the present invention can expand the gauge outfit of IMSI tabulation and IMEI tabulation, increase the sign position of 1bit, whether the IMSI that is using in order to the IMEI and the terminal of marking terminal is general IMEI and IMSI, and for example: home position 0 is expressed as common IMEI or IMSI, and home position 1 is expressed as general purpose I MEI or IMSI; If general purpose I MEI, this IMEI has absolute authority so, can use any USIM; If general purpose I MSI, this IMSI has absolute authority so, can use any ME.
Expansion at this gauge outfit, in the process of carrying out the binding relationship verification, in the signatory IMSI tabulation of the IMEI of inquiry terminal, and during the signatory IMEI tabulation of the IMSI that using of terminal, whether new MME is general purpose I MEI according to the IMEI of the sign position identification terminal of the gauge outfit of IMSI tabulation, and whether the IMSI that is using according to the sign position identification terminal of the gauge outfit of IMEI tabulation is general purpose I MSI; If the IMEI of terminal is general purpose I MEI, and/or the IMSI that terminal is being used is general purpose I MSI, and then the verification of binding relationship is passed through; Otherwise, proceed the binding relationship verification according to aforesaid operations mode one is described.
In order to satisfy the access authentication demand of different stage in the practical application, at aforesaid operations mode two, the present invention can expanded set a bit of sign as the type identification position, whether the IMSI that is using in order to the IMEI and the terminal of marking terminal is general IMEI and IMSI, for example: home position 0 is expressed as common IMEI or IMSI, and home position 1 is expressed as general purpose I MEI or IMSI; If general purpose I MEI, this IMEI has absolute authority so, can use any USIM; If general purpose I MSI, this IMSI has absolute authority so, can use any ME.
Expansion at this gauge outfit, in the process of carrying out the binding relationship verification, the group id that IMEI contracted at inquiry terminal, and terminal using the group id that IMSI contracted the time, whether new MME is general purpose I MEI according to the IMEI of the sign position identification terminal of the signatory group id of IMEI, and whether the IMSI that is using according to the sign position identification terminal of the signatory group id of IMSI is general purpose I MSI; If the IMEI of terminal is general purpose I MEI, and/or the IMSI that terminal is being used is general purpose I MSI, and then the verification of binding relationship is passed through; Otherwise, proceed the binding relationship verification according to aforesaid operations mode two is described.
In embodiments of the invention two, according to method shown in Figure 2, the binding relationship of verification IMEI and IMSI in HSS judges whether to allow to insert, and finally finishes the process that EPS adheres to, and as shown in Figure 4, mainly may further comprise the steps:
The operation of step 401～410 is identical with the operation of middle step 301 embodiment illustrated in fig. 3～310, repeats no more herein.
Step 411, HSS carries out the binding relationship verification according to IMSI entrained in the location update request message and IMEI.
It is pointed out that if the database of HSS is to adopt first kind of maintenance mode, need carry out the binding relationship verification according to mode of operation one so; If the database of HSS is to adopt second kind of maintenance mode, need carry out the binding relationship verification according to mode of operation two so.Repeat no more herein.
Step 412, if verification is passed through, then HSS upgrades response message to new MME home position, comprises user's IMSI and user contracting data in this response message.
Step 413, if verification is not passed through, then HSS returns the subscription data error message to new MME, comprises suitable error reason in this message.
Step 414, if new MME receives position renewal response message, the subsequent process of attachment flow can continue to carry out so.
Step 415, if new MME receives the subscription data error message, so new MME refuses adhering to of terminal, and returns suitable cause value to terminal.
