Abstract

An example method is provided in one example embodiment and may include grouping a plurality of user equipment served by a serving cell radio into one or more groups based on an approximate location of each of the plurality of user equipment and a proximity of each of the plurality of user equipment in relation to each other; selecting a master user equipment for each group; receiving inter-frequency measurement information or inter-Radio Access Technology (RAT) measurement information associated with one or more neighboring cell radios; receiving a first service request for a first user equipment of a particular group; and selecting a particular neighboring cell radio for a service hand-out of the first user equipment based, at least in part, on the first service request and inter-frequency measurement information or inter-RAT measurement information received from a particular master user equipment for the particular group.

Claims

1. A method comprising:

receiving, by a serving cell radio, feedback information for a master user equipment of a user equipment group, wherein the feedback information includes position information associated one or more neighboring cell radios;

communicating, at least in part, the feedback information, a size of the user equipment group and an identifier for the user equipment group to a Self-Organizing Network (SON) server;

determining, by the SON server, management instructions associated with one or more operations to performed by the serving cell radio;

communicating the management instructions to the serving cell radio; and

performing, by the serving cell radio, the one or more operations associated with the management instructions.

2. The method of claim 1, wherein the feedback information includes position information associated with the master user equipment which includes a cell identifier and a signal strength associated with each of the one or more neighboring cell radios.

3. The method of claim 1, wherein the management instructions are associated with one or more operations to perform coordinated resource scheduling for user equipment in the user equipment group with one or more other user equipment groups associated with one or more corresponding neighboring cell radios.

4. The method of claim 3, wherein the coordinated resource scheduling is performed through one or more operations including at least one of:

coordinating resources with the one or more other user equipment groups via an interface connecting the serving cell radio and the one or more corresponding neighboring cell radios; and

coordinating resources with the one or more other user equipment groups according to resource group allocations included in the management instructions from the SON server.

5. The method of claim 3, wherein the management instructions include an identifier for each of the one or more other groups.

6. The method of claim 1, wherein the management instructions are associated with one or more operations to initiate handover of user equipment in the user equipment group to one or more neighboring cell radios.

7. The method of claim 1, wherein communications from the serving cell radio to the SON server further include one or more of:

an available power headroom for the master user equipment;

an average data rate served to user equipment in the user equipment group;

an average uplink Signal to Interference plus Noise Ratio (SINR) for the user equipment group; and

a downlink Block Error Rate (BLER) for user equipment in the user equipment group.

8. The method of claim 1, further comprising:

selecting the master user equipment for the user equipment group based on one of;

its location being at an approximate geographical center of the user equipment group if there are more than two user equipment in the user equipment group; and

its location being closest to the serving cell radio if there are only two user equipment in the user equipment group.

9. One or more non-transitory tangible media encoding logic that includes instructions for execution that when executed by a processor, is operable to perform operations comprising:

receiving, by a serving cell radio, feedback information for a master user equipment of a user equipment group, wherein the feedback information includes position information associated one or more neighboring cell radios;

communicating, at least in part, the feedback information, a size of the user equipment group and an identifier for the user equipment group to a Self-Organizing Network (SON) server;

determining, by the SON server, management instructions associated with one or more operations to performed by the serving cell radio;

communicating the management instructions to the serving cell radio; and

performing, by the serving cell radio, the one or more operations associated with the management instructions.

10. The media of claim 9, wherein the feedback information includes position information associated with the master user equipment which includes a cell identifier and a signal strength associated with each of the one or more neighboring cell radios.

11. The media of claim 9, wherein the management instructions are associated with one or more operations to perform coordinated resource scheduling for user equipment in the user equipment group with one or more other user equipment groups associated with one or more corresponding neighboring cell radios.

12. The media of claim 11, wherein the coordinated resource scheduling is performed through one or more operations including at least one of:

coordinating resources with the one or more other user equipment groups via an interface connecting the serving cell radio and the one or more corresponding neighboring cell radios; and

coordinating resources with the one or more other user equipment groups according to resource group allocations included in the management instructions from the SON server.

13. The media of claim 11, wherein the management instructions include an identifier for each of the one or more other groups.

14. The media of claim 9, wherein the management instructions are associated with one or more operations to initiate handover of user equipment in the user equipment group to one or more neighboring cell radios.

15. The media of claim 9, wherein communications from the serving cell radio to the SON server further include one or more of:

an available power headroom for the master user equipment;

an average data rate served to user equipment in the user equipment group;

an average uplink Signal to Interference plus Noise Ratio (SINR) for the user equipment group; and

a downlink Block Error Rate (BLER) for user equipment in the user equipment group.

16. The media of claim 9, the operations further comprising:

selecting the master user equipment for the user equipment group based on one of;

its location being at an approximate geographical center of the user equipment group if there are more than two user equipment in the user equipment group; and

its location being closest to the serving cell radio if there are only two user equipment in the user equipment group.

17. A system comprising:

at least one memory element for storing data; and

at least one processor that executes instructions associated with the data, wherein the at least one processor and the at least one memory element cooperate such that the system is configured for;

receiving, by a serving cell radio, feedback information for a master user equipment of a user equipment group, wherein the feedback information includes position information associated one or more neighboring cell radios;

communicating, at least in part, the feedback information, a size of the user equipment group and an identifier for the user equipment group to a Self-Organizing Network (SON) server;

determining, by the SON server, management instructions associated with one or more operations to performed by the serving cell radio;

communicating the management instructions to the serving cell radio; and

performing, by the serving cell radio, the one or more operations associated with the management instructions.

18. The system of claim 17, wherein the feedback information includes position information associated with the master user equipment which includes a cell identifier and a signal strength associated with each of the one or more neighboring cell radios.
