Abstract

Method performed by a wireless device (10) for handling neighbour relationships between radio network nodes (12, 13, 15) in a wireless communication network. The wireless device is served by a first radio network node (12) in the wireless communication network (1). The wireless device (10) receives (401), from the first radio network node (12), a report indication indicating that the wireless device is to report information identifying the first radio network node (12) to another radio network node (13). The wireless device receives (402) a signal from a second radio network node (13) which signal is associated with the second radio network node (13); and transmits (405), to the second radio network node (13), the information identifying the first radio network node (12).

First claim

The invention claimed is:

1. A first radio network node configured for handling neighbor relationships between radio network nodes in a wireless communication network, wherein the first radio network node is configured to serve a wireless device in the wireless communication network, the first radio network node comprising:
communication circuitry configured for communicating with the wireless device and other radio network nodes; and
processing circuitry operatively associated with the communication circuitry and configured to:
transmit to the wireless device, a report indication indicating that the wireless device is to report information identifying the first radio network node to another radio network node;
receive a measurement report from the wireless device indicating a signal strength or quality of a second radio network node;
select the second radio network node as a neighboring radio network node based on the received measurement report; and
transmit a selection indication to the wireless device, wherein the selection indication indicates that the wireless device is to report the information identifying the first radio network node to the second radio network node,
wherein the processing circuitry is configured to transmit the report indication or the selection indication and to transmit verification information to verify a connection between the first radio network node and an other radio network node, wherein the processing circuitry is configured to receive the verification information from the second radio network node verifying the connection.

2. The first radio network node according to claim 1 , wherein the report indication further indicates that the information is to be reported to a preferred radio network node.

3. The first radio network node according to claim 1 , wherein the processing circuitry is configured to transmit the report indication or the selection indication and to transmit additional information to the wireless device for being transferred to an other radio network node, wherein the additional information indicates how to contact the first radio network node.

4. The first radio network node according to claim 1 , wherein the processing circuitry is configured to receive a connection request from a second radio network node for establishing a neighbor relationship.

5. A second radio network node configured for handling neighbor relationships between radio network nodes in a wireless communication network, wherein the wireless communication network comprises a first radio network node serving a wireless device, the second radio network node comprising:
communication circuitry configured for communicating with the wireless device and other radio network nodes; and
processing circuitry operatively associated with the communication circuitry and configured to:
transmit a signal to the wireless device, wherein the signal is associated with the second radio network node;
receive, from the wireless device, information identifying the first radio network node, wherein the processing circuitry is configured to receive verification information from the wireless device, wherein the verification information is for verifying a connection between the first radio network node and the second radio network node, wherein the processing circuitry is configured to transmit the verification information to the first radio network node verifying the connection; and
determine whether to establish a neighbor relationship with the first radio network node based on the received information.

6. The second radio network node according to claim 5 , wherein the processing circuitry is configured to receive additional information from the wireless device, wherein the additional information indicates how to contact the first radio network node.

7. The second radio network node according to claim 5 , responsive to establishing the neighbor relationship with the first radio network node and the second radio network node, the processing circuitry is configured to transmit a connection request to the first radio network node for establishing the neighbor relationship using the received information identifying the first radio network node and/or the received additional information.

8. The second radio network node according to claim 5 , wherein the processing circuitry is configured to retrieve address information for the first radio network node from another network node and use the address information to establish a connection to the first radio network node.
