METHOD AND SYSTEM FOR REQUESTING PHYSICAL MULTICAST CHANNEL

摘要

A method and system for requesting a Physical PMCH are provided. The method includes: user equipment determines a target cell to be immigrated which is adjacent to a cell where the user equipment is located; and if the user equipment judges that a preconfigured Multicast Broadcast Single Frequency Network (MBSFN) area in the adjacent target cell does not comprise the MBSFN area used by the Multimedia Broadcast Multicast Service (MBMS) service/group call currently received by the user equipment, the user equipment requests a network side equipment to allocate a PMCH for the currently received MBMS service/group call. According to the technical solution provided in the present invention, the service continuity of the PTT communication user in a receiving state during the moving process is implemented.
