Abstract
A synchronization method, a communication handover method, a radio network, and a RAN node are disclosed. The interface information synchronization method includes determining whether a condition for initiating interface information update is fulfilled. Information about the S1 interface between the RAN node and the core network node, is sent. In addition, or alternatively, information about the X2 interface between the RAN node and the neighboring RAN node is sent to the neighboring RAN node if the condition for initiating interface information update fulfilled.
Claims12
An interface information synchronization method, comprising:
- receiving, by a second radio access network (RAN) node, interface information sent by a first RAN node through an X2 interface, wherein the interface information is sent by the first RAN node when a condition for sending interface information is fulfilled, the interface information including information indicating whether an S1 interface exists between the first RAN node and a core network node, wherein the X2 interface is between the first RAN node and the second RAN node;
- and
- updating, by the second RAN node, interface information of the second RAN node according to the received interface information.
A second radio access network (RAN) node, comprising:
- a receiver, configured to receive interface information sent by a first RAN node through an X2 interface, wherein the interface information comes from the first RAN node when a condition for sending interface information is fulfilled, the interface information including information indicating whether an S1 interface exists between the first RAN node and a core network node, wherein the X2 interface is between the first RAN node and the second RAN node;
- and
- a processor, configured to update interface information of the second RAN node according to the interface information received by the receiver.
