摘要： A method for detachment of a mobile set within the equivalent route area moving between the communication systems comprising steps of: during the detachment process is implemented between a mobile set and a service node in one communication system, the service node generates one or more messages and transmits it to the service nodes in one or more communication system within the ERA. If the message is transmitted to the service node within the ERA of only one communication system, this service node transmits this message or the message generated according to this message to the service nodes within the ERA of the other communication system. With the method proposed in present invention, when a mobile is detached from two or more communication systems which share the same ERA, the service nodes in all communication systems within the ERA can still correctly manage the relevant information on this mobile set.

摘要： The method for supporting combinatorial CS call and IMS session that includes initiating an IMS domain session or sending a IMS relevant signaling to a called subscriber by a UE A, indicating a unique identification of the called terminal and checking whether his/her own identification matches with the unique one included in the message or not by the called. If a match is detected, sending back a normal response message. Otherwise, an abnormal one or none at all is sent back. Then, the several responses are combined and forwarded by a S-CSCF of the called according to available regulations. Thus, errors caused at the moment of terminal ability exchanging or session being established can be effectively avoided and the IMS unregistered UE can also share the IMS service.

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.
