A method for implementing Multimedia Broadcast/Multicast Service MBMS, wherein MBMS are born on different multimedia broadcast multicast bearers, and each multimedia broadcast multicast bearer corresponds to a multimedia broadcast multicast area respectively, comprising: establishing an association relationship between different multimedia broadcast multicast bearers associated with MBMS of a same type at a network side; and in response to a User Equipment UE switching between different multimedia broadcast multicast areas, the network side providing the UE with a multimedia broadcast multicast bearer of a multimedia broadcast multicast area where the UE is located currently, according to the association relationship between different multimedia broadcast multicast bearers corresponding to the MBMS requested by the UE; wherein the process of establishing the association relationship between different multimedia broadcast multicast bearers associated with MBMS of a same type comprises: Making the different multimedia broadcast multicast bearers correspond to a same service ID associated with MBMS of a same type; or Using different service IDs associated with MBMS of a same type to identify the different multimedia broadcast multicast bearers, and setting the service IDs as equivalence; wherein the process of making the different multimedia broadcast multicast bearers correspond to the same service ID associated with MBMS of a same type comprises: setting in a Broadcast Multicast-Service Center BM-SC, a multimedia broadcast multicast service management table, recording a corresponding relationship among a service ID, at least one local multimedia broadcast multicast area, and at least one multimedia multicast address, wherein one local multimedia broadcast multicast area and one multicast address correspond to one multimedia broadcast multicast bearer; and wherein the process of using the different service IDs associated with MBMS of a same type to identify the different multimedia broadcast multicast bearers and setting the service IDs as the equivalence comprises: setting in a Broadcast Multicast-Service Center BM-SC, a multimedia broadcast multicast service management table, recording the corresponding relationship among a service ID, a local multimedia broadcast multicast area and a multimedia multicast address, and recording an equivalence relationship between different service IDs. establishing an association relationship between different multimedia broadcast multicast bearers associated with MBMS of a same type at a network side; and in response to a User Equipment UE switching between different multimedia broadcast multicast areas, the network side providing the UE with a multimedia broadcast multicast bearer of a multimedia broadcast multicast area where the UE is located currently, according to the association relationship between different multimedia broadcast multicast bearers corresponding to the MBMS requested by the UE; Making the different multimedia broadcast multicast bearers correspond to a same service ID associated with MBMS of a same type; or Using different service IDs associated with MBMS of a same type to identify the different multimedia broadcast multicast bearers, and setting the service IDs as equivalence; setting in a Broadcast Multicast-Service Center BM-SC, a multimedia broadcast multicast service management table, recording a corresponding relationship among a service ID, at least one local multimedia broadcast multicast area, and at least one multimedia multicast address, wherein one local multimedia broadcast multicast area and one multicast address correspond to one multimedia broadcast multicast bearer; and wherein the process of using the different service IDs associated with MBMS of a same type to identify the different multimedia broadcast multicast bearers and setting the service IDs as the equivalence comprises: setting in a Broadcast Multicast-Service Center BM-SC, a multimedia broadcast multicast service management table, recording the corresponding relationship among a service ID, a local multimedia broadcast multicast area and a multimedia multicast address, and recording an equivalence relationship between different service IDs. setting in a Broadcast Multicast-Service Center BM-SC, a multimedia broadcast multicast service management table, recording the corresponding relationship among a service ID, a local multimedia broadcast multicast area and a multimedia multicast address, and recording an equivalence relationship between different service IDs.
