It is to be noted, the present invention can record its signing IMEI list for each signing IMSI in the database of HSS, and record its signing IMSI list for IMEI of the signing binding of each application IMSI, adopt above-mentioned the first maintenance mode by HSS, the corresponding relation of storage maintaining IMS I and IMEI.Certainly, also can adopt above-mentioned the first maintenance mode by EIR, the corresponding relation of storage maintaining IMS I and IMEI.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, the IMSI used due to IMEI and the terminal of terminal, therefore by MME, collected at first, the mode of operation one of above-mentioned inquiry and binding relationship verification also can be carried out by MME, just needs HSS to provide the corresponding relation inquiry service of IMSI and IMEI for MME.
Also can adopt the second maintenance mode in the database of HSS, the group sign that the group sign that storage maintaining IMS I are signing and IMEI are signing.So corresponding, the mode of operation two of above-mentioned inquiry and binding relationship verification can be carried out by HSS.In addition, the IMSI because IMEI and the terminal of terminal are being used, collected by MME at first, and therefore the mode of operation two of above-mentioned inquiry and binding relationship verification also can be carried out by MME, the inquiry service that just needs HSS to provide group to identify for MME.
Method of calibration below in conjunction with specific embodiment to above-mentioned IMSI and IMEI binding relationship further elaborates.
In embodiments of the invention one, according to the method shown in Fig. 2, the binding relationship of verification IMEI and IMSI in MME, judge whether to allow access, and finally complete the process that EPS adheres to, and as shown in Figure 3, mainly comprises the following steps:
Step 301, terminal is initiated initially to adhere to, to base station (eNB, evolved NodeB) the transmission Attach Request message of evolution.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 Attach Request message, and this Attach Request message is sent to the new MME of selection.
Step 303, if that carry in Attach Request message is old GUTI, and current new MME is not the MME of terminal while adhering to last time, new MME need obtain from old MME/SGSN the identity informations such as IMSI, untapped authentication vector, key, and according to the identity information obtained, Attach Request message is carried out to completeness check.
Step 304, if terminal does not all have record in new MME, old MME/SGSN, 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 step 301 does not have integrity protection, if then or adhere to request by completeness check, 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, at first HSS searches the corresponding user contracting data of IMSI in the authorization data request message, if search less than any signing or IMSI, is put on the blacklist, and HSS returns to authorization data to new MME and responds and carry suitable error reason; If find the user contracting data corresponding with IMSI, HSS returns to the authorization data response message to new MME, in this response message, comprises authentication vector.
Step 307, if carried out step 305 and 306, just must carry out the legitimacy of authorizing procedure with verification terminal IMSI between so new MME and 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.Because safety connects, set up, so this identity request message, identity response message are encrypted transmission.
Step 309, if network design EIR, MME can select to the legitimacy of the IMEI of EIR inquiry terminal.
Step 310, new MME sends location update request message to HSS, comprises 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, this position is upgraded in response message so needs the user contracting data that comprises terminal, user's the legal IMEI list that IMSI contracted, the legal IMSI list that IMEI contracted of terminal; If adopt aforesaid operations mode two, the group sign that the user contracting data that needs to comprise terminal, user's IMSI is corresponding, the group sign corresponding to IMEI of terminal are upgraded in response message in this position so.
Step 312, new MME upgrades entrained information in response message according to position, and the IMEI of terminal and the IMSI used are carried out to the binding relationship verification.
If the user contracting data that comprises terminal in response message, user's the legal IMEI list that IMSI contracted, the legal IMSI list that IMEI contracted of terminal are upgraded in the position that HSS returns, the IMSI that so new MME need to used according to IMEI and the terminal of a pair of terminal of aforesaid operations mode carries out the binding relationship verification.If the user contracting data that comprises terminal in the position that HSS returns renewal response message, the group sign that user's IMSI is corresponding, the group sign corresponding to IMEI of terminal, the IMSI that so new MME need to used according to IMEI and the terminal of two pairs of terminals of aforesaid operations mode carries out the binding relationship verification.
Step 313, if verification is passed through, continue to carry out the subsequent process of attachment flow.
Step 314, if verification is not passed through, new MME refuses the request of adhering to of terminal, and returns to suitable cause value to terminal.
It should be noted that, for aforesaid operations mode one, according to the needs of operator, if search the IMSI used less than IMEI or the terminal of terminal in the record of HSS database, can select to refuse the terminal access, also can be used as the list that IMEI or IMSI are corresponding is that sky is processed; For aforesaid operations mode two, if search the IMSI used less than IMEI or the terminal of terminal in the record of HSS database, can select to refuse the terminal access, the not situation of group sign of also can being used as is processed.
In addition, in order to meet the access authentication demand of different stage in practical application, for aforesaid operations mode one, the present invention can expand the gauge outfit of IMSI list and IMEI list, increase the flag of 1bit, whether the IMSI used in order to 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.
