摘要： A method for supporting Multicast Broadcast Multimedia Service (MBMS) data transmission in a Long-term evolution (LTE) system includes a network entity (ECN) to which a user equipment (UE) is registered, receives an Activate MBMS context request message from the UE, and sends a Create MBMS UE Context Request message to a ECN that offers MBMS service. The ECN that offers MBMS service performs an authorization process with a Broadcast and Multicast Service Center (BM-SC) and sends a “Create MBMS UE Context Response” message to the ECN to which the UE is registered. The ECN to which the UE is registered sends an Activate MBMS Context Accept message to the UE. With the methods for supporting the transmission of MBMS data in the LTE system according to present invention, both the BM-SC and the ECN can find the downstream node so that service transmission paths may be found for MBMS data.

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： 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： A method for key management and assignment in MBMS service, the method includes following steps: the group key locates in the root node on the highest layer, which only has child nodes and doesn't have parent nodes; private keys corresponding to users locate in leaf nodes; the described intermediate node that owns both one parent node and one or more child nodes holds it own key. This invention deploys the method of combining point-to-point mode and point-to-multipoint mode during the process of key update; compared with the key update method only deploying point-to-point mode, this method can reduce the times necessary for information transmission, reduce the system load as well as the time needed for one key update process. Compared with the key update method only deploying point-to-multipoint mode, this solves the security problem of key exposure.
