The technical solution of the present invention is further elaborated below in conjunction with the drawings and specific embodiments.
The distribution method of a kind of mobile station identification provided by the invention as shown in Figure 1, mainly may further comprise the steps:
When terminal initial networked or networks again, network side need carry out authentication based on EAP to the terminal that networks; Behind the EAP authentication success, be this terminal distribution STID by the base station that terminal connected.The STID that distributes is used for this terminal of unique identification in this base station scope.
In the present invention, the reciprocal process of base station and terminal comprises: to the three-way handshake process that the authorization key (AK, Authorization Key) that is derived from behind the EAP Certificate Authority is verified, registration message reciprocal process when perhaps endpoint registration is to the base station or the like.In addition, terminal withdraws from the process in handoff procedure, position updating process and free time (Idle) pattern, and the base station also needs to distribute the STID of renewal to send to terminal.Certainly, the reciprocal process of indication base station and terminal among the present invention is not limited only to above-mentioned the act, can also expand according to actual needs.
The base station can with the three-way handshake process of terminal in to terminal distribution STID, the embodiment to distribution STID in three-way handshake process is elaborated below, as shown in Figure 2, mainly may further comprise the steps:
Step 201, when terminal initial networks or networks again, the EAP process that the base station assists terminal and network side to finish initial authentication or authenticate again.
Step 202, based on the initial authentication of EAP or again behind the authentication success, in order to verify the legitimacy of the AK that EAP authentication back is derived from, terminal and base station begin to carry out the proof procedure based on the three-way handshake of IKMP version 2 (PKMv2, Privacy Key Management); And at first sending checking challenge (PKMv2-RSP/SA-TEK-Challenge) message to terminal by the base station, this message has been determined the AK that uses.
After step 203, terminal are received PKMv2-RSP/SA-TEK-Challenge message, the legitimacy of AK is verified, and after being proved to be successful, sent checking request (PKMv2-REQ/SA-TEK-Request) message to the base station according to verification algorithm.
Step 204, after the base station receives PKMv2-REQ/SA-TEK-Request message, according to verification algorithm the legitimacy of AK is verified, if be proved to be successful, then be STID of terminal Random assignment, and the STID that distributes is carried in auth response (PKMv2-RSP/SA-TEK-Response) message sends to terminal.
It is pointed out that the mapping relations that need safeguard STID and terminal MAC Address at network side, these mapping relations need be protected, and therefore when the base station need be sent as the STID of terminal distribution, this STID need protect transmission; And only finish at the EAP authentication success, the AK of generation could protect transmission to STID after succeeding and verifying.
If the base station sends to the PKMv2-RSP/SA-TEK-Response message of terminal Confidentiality protection is arranged, then STID directly can be carried in the PKMv2-RSP/SA-TEK-Response message and send to terminal; If the base station sends to the PKMv2-RSP/SA-TEK-Response message of terminal and does not do Confidentiality protection; then can adopt key-encrypting key (KEK; Key Encrypting Key) or traffic encryption key (TEK, Traffic Encrypting Key) etc. be carried in the PKMv2-RSP/SA-TEK-Response message after STID is encrypted and send to terminal.Security parameters such as cryptographic algorithm to STID encrypts can be undertaken pre-configured or the generation of holding consultation in three-way handshake process by base station and terminal.
The base station can also be to terminal distribution STID in the registration process of terminal, and the embodiment to distribution STID in registration message reciprocal process is elaborated below, as shown in Figure 3, mainly may further comprise the steps:
Step 301, when terminal initial networks or networks again, the EAP process that the base station assists terminal and network side to finish initial authentication or authenticate again.
Step 302, based on the initial authentication of EAP or again behind the authentication success, the proof procedure based on the three-way handshake of PKMv2 is carried out in terminal and base station, the legitimacy of the AK that is produced with checking EAP authentication.
Step 303, after the legitimate verification success of AK, terminal sends register requirement (REG-REQ, Register Request) message to the base station, and request is to base station login.
Step 304, base station will be carried at the registration response for the STID of terminal distribution, and (REG-RSP RegisterResponse) sends to terminal in the message.
It is pointed out that if the base station sends to the REG-RSP message of terminal has Confidentiality protection, then STID directly can be carried in the REG-RSP message and send to terminal; If the base station sends to the REG-RSP message of terminal and do not do Confidentiality protection, be carried in the REG-RSP message after then can adopting KEK or TEK etc. that STID is encrypted and send to terminal.Security parameters such as cryptographic algorithm to STID encrypts can be undertaken pre-configured or the generation of holding consultation in three-way handshake process by base station and terminal.
When terminal need be carried out the service switching of base station, the target BS that terminal will switch to need be the STID that terminal distribution is upgraded, and target BS can send to terminal with the STID that upgrades in range finding (Ranging) process.Concrete operations mainly may further comprise the steps as shown in Figure 4:
Step 401, terminal send terminal to current serving BS and switch indication (MOB HO-IND) message, need switch to target BS with this terminal of notification service base station.
Step 402, serving BS and target BS carry out switch acknowledgment message reciprocal process, promptly will switch to target BS affirmation terminal.
Step 403, terminal is carried out re-networking process at target BS, and sends distance measurement request (RNG-REQ, Ranging Request) message to target BS.
Step 404, target BS are the STID that terminal distribution is upgraded, and the STID that distributes is carried in ranging response (RNG-RSP, the Ranging Response) message sends to terminal.After this target BS and terminal promptly can use the STID of this renewal to come the marking terminal identity.
The STID that upgrades can be identical at the STID that serving BS is assigned with terminal, also can be different, but need guarantee that the STID that distributes can this terminal of unique identification in target BS.
It is pointed out that if target BS sends to the RNG-RSP message of terminal has Confidentiality protection, then STID directly can be carried in the RNG-RSP message and send to terminal; If target BS sends to the RNG-RSP message of terminal and do not do Confidentiality protection, be carried in the RNG-RSP message after then can adopting KEK or TEK etc. that STID is encrypted and send to terminal.The AK that encryption keys such as KEK that target BS adopts or TEK are used by serving BS recomputates in target BS and obtains; And the AK that serving BS uses can carry out sending to target BS in the mutual process of switch acknowledgment message with target BS.
In addition, the security parameters such as cryptographic algorithm to STID encrypts can be undertaken pre-configured by system; Perhaps in switching set-up procedure, when switching interacting message, serving BS and target BS send to target BS by serving BS, or serving BS GC group connector and target BS hold consultation, and the security parameters such as STID cryptographic algorithm that serving BS is determined negotiation result are carried on and send to terminal in the switching response message (MOB BSHO-RSP); Perhaps in switching implementation process, serving BS and target BS carry out switch acknowledgment message when mutual, send to target BS by serving BS.
When terminal need be carried out the service switching of base station, target BS also can send to terminal with the STID that upgrades in switching set-up procedure.Concrete operations mainly may further comprise the steps as shown in Figure 5:
Step 501, terminal sends handoff request (MOB MSHO-REQ) message to serving BS, and request is switched.
Step 502, serving BS sends handoff request message to target BS.
Can the STID of carried terminal in serving BS in the handoff request message that sends, and/or security parameter such as STID cryptographic algorithm.
Step 503, target BS are the STID that terminal distribution is upgraded, and the STID that upgrades is carried at sends to terminal in the switching response message.
This message is carried parameter and can also be comprised: the SITD of renewal and the mapping relations of former STID, and/or security parameter such as STID cryptographic algorithm.
The STID that upgrades can be identical at the STID that serving BS is assigned with terminal, also can be different, but need guarantee that the STID that distributes can this terminal of unique identification in target BS.For example: the STID of terminal in serving BS that carries in the handoff request message of target BS according to the serving BS transmission, check whether this STID distributes in target BS, if do not distribute, then target BS still can be the identical STID of this terminal distribution; If distribute, then the target BS STID that generates other at random sends to terminal.
Step 504, serving BS sends switching response message (MOB BSHO-RSP) to terminal, carries the STID sign of renewal, and/or security parameter such as STID cryptographic algorithm.
It is pointed out that if target BS sends to the switching response message of terminal has Confidentiality protection, then STID directly can be carried at and send to terminal in the switching response message; If target BS sends to the switching response message of terminal and do not do Confidentiality protection, be carried at after then can adopting KEK or TEK etc. that STID is encrypted and send to terminal in the switching response message.
By operation shown in Figure 5, terminal is after this in the Ranging process that target BS switches, and target BS and terminal promptly can use the STID of this renewal to come the marking terminal identity; In the broadcast that target BS sends, can use the STID of renewal to determine the Resource Block of terminal initiation Ranging process; Terminal can directly send RNG-REQ message on the Resource Block of this appointment, to reduce the break period of handoff procedure, accelerate switch speed.
When terminal was carried out the position renewal or withdrawed from the Idle pattern at needs, the base station also needed the STID for the terminal distribution renewal, and the operation of the STID that the base station distribution is upgraded in this process as shown in Figure 6, mainly may further comprise the steps:
Step 601 is upgraded in the position or when withdrawing from Idle pattern trigger condition and satisfying, terminal sends RNG-REQ message to the base station.
Step 602, base station are the STID that terminal distribution is upgraded, and the STID that distributes is carried in the RNG-RSP message sends to terminal.
Same, if the base station sends to the RNG-RSP message of terminal Confidentiality protection is arranged, then STID directly can be carried in the RNG-RSP message and send to terminal; If the base station sends to the RNG-RSP message of terminal and do not do Confidentiality protection, be carried in the RNG-RSP message after then can adopting KEK or TEK etc. that STID is encrypted and send to terminal.
In addition, for position updating process, after having distributed the STID that upgrades, during the base station calling terminal, can in beep-page message, add the STID that upgrades and come this terminal of paging; For withdrawing from the Idle mode process, after having distributed the STID that upgrades, the STID that can use this renewal that communicates by letter of terminal and base station comes the marking terminal identity.
The distribution method of mobile station identification provided by the present invention is not limited to IEEE 802.16 systems, and its associative mode of realizing the sign distribution also is applicable in other wireless communication systems.
