摘要： A method for managing key in Multimedia Broadcast/Multicast service comprising steps of defining a valid MTK ID interval for each generated MSK and sends it to a UE along with a MSK by a BMSC; after receiving the MSK, saving a valid MTK ID interval of the MSK by the UE; and defining a MTK ID for each generated MTK encrypted with the MSK and sending the MTK ID and the MTK to the UE after encrypting them with the MSK by the BMSC This MSK is valid only when the transmission of the MTK within MTK ID interval is in operation. Therefore, once the UE finds out that some newly received MTK's MTK ID is beyond said MTK ID, it deletes the MSK that is applied in said MTK transmission's encryption correspondingly.

摘要： An embodiment of the present invention provides a method for user pairing test, applicable to a GERAN/VAMOS system. In the method, a time condition for stress test is preset and a base station selects two users as candidate users. Then, when the time condition for the stress test is satisfied, the base station instructs one of the candidate users to perform the stress test on a slot of the other candidate user and to report a channel condition. Next, the base station adjusts transmission power of the two candidate users according to channel conditions reported by the two candidate users, and when channel qualities of the candidate users meet channel quality requirements, multiplex the two candidate users onto a same time-frequency resource and releases redundant time-frequency resources. Another embodiment of the present invention provides another method for user pairing test. According to the methods, mobile stations of users are not required to support multi-slot processing and no additional slot is required. The user pairing test can still be realized, the system capacity is increased and the system call drop probability is reduced.
