Problems solved by technology

[0008] However, there is currently no feasible implementation solution that can ensure that the target base station can reliably obtain the corresponding security negotiation parameter information after the handover occurs, so that the communication performance after the handover cannot be reliably guaranteed

Embodiment 1

[0053] In this embodiment, the security negotiation parameter information is transmitted through the handover preparation process, specifically as shown in Figure 2, including:

[0054] Step 21: The serving base station judges that the handover preparation process of a certain mobile terminal is currently in progress, and it is determined that the optimization parameters of the handover process indicate to omit the basic capability negotiation process of the subscribing station, then it will send a handover request message to the candidate target base station, and the handover request message contains Contains the security negotiation parameter information corresponding to the corresponding mobile terminal;

[0055] The security negotiation parameters that must be included in the message are: message authentication code mode. Optional include: authorization policy support, key management protocol version support, package serial number window size.

[0056] Step 22: After rece...

Embodiment 2

[0058]In this embodiment, the security negotiation parameter information is transmitted through the handover confirmation process, as shown in FIG. 3 , specifically including:

[0059] Step 31: The mobile terminal sends a handover indication message to the serving base station, and the message includes the identifier of the target base station;

[0060] Step 32: The serving base station judges the optimization parameters of the handover process to determine whether the target base station omits the basic capability negotiation process of the subscribing station: if it is judged that the target base station omits the basic capability negotiation process of the subscribing station or cannot be judged, it needs to include in the handover confirmation message Security negotiation parameters, otherwise, it is not necessary to carry the security negotiation parameters in the handover confirmation message;

[0061] The security negotiation parameters that must be included in the hand...

Embodiment 3

[0063] In this embodiment, the security negotiation parameter information is transmitted through an abnormal handover process, as shown in FIG. 4 specifically, including:

[0064] Step 41: the mobile terminal sends a RNG-REQ (paging request) message to the target base station;

[0065] Step 42: The target base station finds that it is the RNG-REQ message after the handover, and will send a session information request message to the serving base station, and the message must contain the identifier of the mobile terminal;

[0066] Step 43: The serving base station replies the session information response message to the target base station. Before replying the session information response message, it needs to judge whether the switching process optimization parameters of the target base station indicate to omit the subscription station capability negotiation process. If it cannot be judged or it is judged to omit the subscription station capability negotiation process, the securi...

Abstract

A method for confirming safety consultation parameter in switching over process includes confirming that switch-over is occurred on mobile terminal by service base station of mobile terminal then sending safety consultation parameter information corresponding said mobile terminal to object base station by service base station to let switched-over object base station obtain mobile terminal safety consultation parameter obtained by consultation of service base station.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a handover processing technology related to security negotiation parameters. Background technique [0002] In a wireless communication system, a mobile terminal often moves from a base station coverage area to another base station coverage area due to its mobility. To this end, it is necessary to implement a corresponding handover process in the communication system. [0003] In the handover process, in order to ensure that the handover mobile terminal can still carry out communication services safely, it is necessary to transmit the corresponding security information from the serving base station to the target base station during the handover process. Currently, the security information that needs to be transmitted during the handover process The information includes: content in the context of the authorization key and content in the context of the security assoc...
