Message handling method and device
View Patent ↗In the field of communications technologies, a method and a device for handling messages 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 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 solutions can ensure normal communication, and reduce possibility of communication failure.
1. A method for handling messages, comprising:
generating a notification by a serving node, wherein the notification carries information that a neighbor cell which belongs to a neighbor node is being marked as a serving cell of a serving node to serve a Relay Node (RN), wherein the neighbor node being different from the serving node; and
sending by the serving node, the notification to the RN to indicate the neighbor cell marked as the serving cell to the RN;
wherein the method is characterized by that
the serving node is a serving evolved NodeB (eNB), the neighbor node is a neighbor eNB coupled with the serving eNB through an S1 interface or an X2 interface, the RN is coupled with the serving eNB through a Un interface, and
when the serving node generates the notification, the neighbor cell which has been marked as the serving cell is used to indicate that the X2 interface between the neighbor eNB and the serving eNB is available, and the RN is further capable of acquiring that the X2 interface between the neighbor eNB and the serving eNB is available on basis of the mark in the notification.
2. The method according to claim 1 , wherein the neighbor cell marked as the serving cell of the serving node is included in an eNB serving cell table in the notification.
3. A message handling device in a serving node, comprising a hardware processor and a non-transitory memory coupled to the hardware processor; wherein the non-transitory memory comprises program codes which is capable of being read out and being executed by the hardware processor to perform the steps of:
generating a notification, wherein the notification carries information that a neighbor cell which belongs to a neighbor node is being marked as a serving cell of the serving node to serve a Relay Node (RN), wherein the neighbor node being different from the serving node; and
sending the notification to the RN to indicate the neighbor cell marked as the serving cell to the RN;
wherein the device is characterized by that
the serving node is a serving evolved NodeB (eNB), the neighbor node is a neighbor eNB coupled with the serving eNB through an S1 interface or an X2 interface, the RN is coupled with the serving eNB through a Un interface, and
when generating the notification, the neighbor cell which has been marked as the serving cell is used to indicate that the X2 interface between the neighbor eNB and the serving eNB is available, and the RN is further capable of acquiring that the X2 interface between the neighbor eNB and the serving eNB is available on basis of the mark in the notification.
4. The device according to claim 3 , wherein the neighbor cell marked as the serving cell of the serving node is included in an eNB serving cell table in the notification.
5. A wireless communication network, comprising: a serving node, a neighbor node different from the serving node, and a Relay Node (RN) served by the serving node;
wherein the serving node is configured to generate a notification and transmit the notification to the RN, wherein the notification carries information that a neighbor cell which belongs to the neighbor node is being marked as a serving cell of the serving node; and
the RN is configured to receive the notification from the serving node;
wherein the wireless communication network is characterized by that
the serving node is a serving evolved NodeB (eNB), the neighbor node is a neighbor eNB coupled with the serving eNB through an S1 interface or an X2 interface, the RN is coupled with the serving eNB through a Un interface, and
when the serving eNB generates the notification, the neighbor cell which has been marked as the serving cell is used to indicate that the X2 interface between the neighbor eNB and the serving eNB is available, and the RN is further capable of acquiring that the X2 interface between the neighbor eNB and the serving eNB is available on basis of the mark in the notification.
6. The wireless communication network according to claim 5 , wherein the neighbor cell marked as the serving cell of the serving node is included in an eNB serving cell table in the notification generated by the serving node.
