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; and sending information about the S1 interface between the RAN node and the core network node, and/or information about the X2 interface between the RAN node and the neighboring RAN node to the neighboring RAN node if the condition for initiating interface information update fulfilled.
Claims11
An interface information synchronization method, comprising:
- sending, by a radio access network (RAN) node, interface information to a neighboring RAN node through an X2 interface, wherein the X2 interface is between the RAN node and the neighboring RAN node;
- wherein the interface information comprises information about whether an S1 interface exists, wherein the S1 interface is between the RAN node and a core network node;
- receiving, by the neighboring RAN node, the interface information;
- updating, by the neighboring RAN node, interface information of the neighboring RAN node according to the received interface information.
A radio network, comprising a first Radio Access Network (RAN) node, a second RAN node, and a core network node, the core network node is a serving core network node of the second RAN node;
- wherein the first RAN node comprises:
- a sending unit, configured to send interface information to the second RAN node through an X2 interface, wherein the X2 interface is between the first RAN node and the second RAN node;
- wherein the interface information comprises information about whether an S1 interface exists, wherein the S1 interface is between the first RAN node and the core network node;
- wherein the second RAN node comprises:
- a receiving unit, configured to receive the interface information;
- a processing unit, configured to update interface information of the second RAN node according to the received interface information.
A radio access network (RAN) node, comprising:
- a receiving unit, configured to receive interface information, wherein the interface information is sent from a first RAN node through an X2 interface, wherein the X2 interface is between the RAN node and the first RAN node, and the interface information comprises information about whether an S1 interface exists, wherein the S1 interface is between the first RAN node and a core network node;
- and
- a processing unit, configured to update interface information of the RAN node according to the received interface information.
