The present invention provides a method and system for indicating data offload, and a traffic offload network element, the method comprises: when a radio bearer is established or modified, a mobility management unit of a core network notifies a traffic offload network element of the bearer type of the bearer to determine whether to start the data offload. Through the present invention, the judgment operation of the core network is simplified. In addition, under the situation that the core network side determines whether to start local access function, the traffic offload network element also can correctly start an offload policy.

Method, system and transmission distribution network element for indicating data-distribution

The present invention provides an intra-system handoff method, comprising the following steps: S, when deciding a handoff of UE to a target base station, a source base station issues a handoff request to the target base station; S, in response to the handoff request from the source base station, the target base station informs the source base station to conduct handoff for the UE; S, after the completion of the handoff, the target base station issues an update request to an MME; and S, in response to the update request from the target base station, the MME conducts Serving GW selection, and further fulfils the intra-system handoff. By the present invention, the target eNodeB need not determine whether access to the Serving GW is available, and accordingly the target eNodeB can avoid from configuring Serving GW.
