Abstract: 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.

Abstract: A method and apparatus for processing an IMS terminal's call request for real-time service and non-real-time service received over an IMS domain in a CSI terminal. When deciding to use a CS call for real-time service and an IMS session for non-real-time service, the CSI terminal sends an IMS session response for the non-real-time service. In the mean time, the CSI terminal generates a CS call request for the real-time service and sends the CS call request to an AS in an IMS domain. The AS sends the CS call request in association with the IMS session response to the IMS terminal, thereby completing a call setup. For the association, the AS sends its MSISDN to the CSI terminal and identifies from the MSISDN included in the CS call request and the IMS session response that the two messages are related to the IMS terminal's call request.

Abstract: 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.
