Abstract

Systems and methods that enable a network to configure its neighbor relation (e.g., automatically) by commanding each user equipment (UE) to scan its respective area for neighbor base stations on a predetermined frequency or radio access technology. Moreover, the network can compile lists (e.g., whitelists that identify base stations associated with the network, and black lists that indicate base stations associated with foreign networks) and advise the UEs accordingly (e.g., regarding possibilities for availability of base stations.) The network can therefore configure its neighbor relations automatically and with a higher precision as compared to manual configurations.

Claims

1. A method of self configuring neighbor relations of a network comprising:

commanding one or more user equipments (UEs) to scan for neighbor base stations;

receiving data identifying the neighbor base stations from the one or more UEs;

analyzing the data identifying the neighbor base stations;

collecting additional information, from the one or more UEs, for one or more of the neighbor base stations based on said analysis; and

self configuring neighbor relations based on received data and collected additional information.

2. The method of claim 1, wherein said self configuring is performed automatically.

3. The method of claim 1, further comprising compiling at least one of black lists, white lists, and a combination thereof for the one or more UEs, to facilitate accessing base stations.

4. The method of claim 1 further comprising commanding the one or more UEs based on a predetermined triggering event.

5. The method of claim 1, further comprising scanning for a base station on a predetermined frequency.

6. The method of claim 1, further comprising scanning for a base station on a predetermined radio access technology.

7. A wireless communications apparatus, comprising:

at least one processor configured to;

instruct one or more user equipments (UEs) to scan for base stations;

receive data identifying the base stations from the one or more UEs;

analyze the data identifying the neighbor base stations;

collect additional information, from the one or more UEs, for one or more of the neighbor base stations based on said analysis; and

self configure neighbor relations associated with the base stations based on received data and collected additional information.

8. The wireless communication apparatus of claim 7, wherein the at least one processor is further configured to generate accessibility lists to facilitate accessing the base stations.

9. The wireless communication apparatus of claim 8, wherein the at least one processor is further configured to automatically self configure neighbor relations.
