SYNCHRONIZATION METHOD, COMMUNICATION HANDOVER METHOD, RADIO NETWORK AND NODE

摘要

A synchronization method, communication handover method, radio network and network node of radio access network. The interface information synchronization method comprises: judging whether the condition of triggering the interface information update is met; when the condition of triggering the interface information update is met, sending the information of the S1 interface between a network node of this radio access network and the core network node, and/or the X2 interface between the network node of this radio access network and a network node of the adjacent radio access network to the network node of the adjacent radio access network.
