Message handling method and device

摘要

In the field of communications technologies, a message handling method and a message handling device are provided. The method includes: a notification indicating whether an X2 interface to a neighbor node is available is received; using an S1 interface to send information when the X2 interface is unavailable; and/or receiving a notification indicating whether an S1 interface to a neighbor node is available, and using an X2 interface to send information when the S1 interface is unavailable. The technical solutions can ensure normal communication, and reduce possibility of communication failure.

1. A wireless communication network, comprising:
a serving node, a neighboring node different from the serving node, and a relay node different from the neighboring node, wherein the relay node is served by the serving node; wherein the serving node is configured to generate a notification which indicates that an X2 interface between the neighboring node and the serving node is available, and transmit the notification to the relay node, wherein the availability of the X2 interface is indicated in the notification by marking a neighboring cell which belongs to the neighboring node as a serving cell of the serving node; and the relay node is configured to:
receive the notification from the serving node, anddetermine that the X2 interface between the neighboring node and the serving node is available based on the indication that the neighboring cell which belongs to the neighboring node is marked as the serving cell of the serving node; wherein the serving node is a serving evolved NodeB (eNB), the neighboring node is a neighboring eNB coupled with the serving eNB through an S1 interface or the X2 interface, the relay node is coupled with the serving eNB through a Un interface.
