Abstract

A cell reselection procedure in heterogeneous networks is enhanced based on utilization of per category cell reselection parameters. In one aspect, a serving access point can categorize a set of neighbor access points based on cell-type and/or cell-profile data of a set of neighbor access points. Further, the serving access point can determine cell reselection parameters for the different categories. As an example, offset data (Qoffset) can be determined for the different categories. The per category cell reselection parameters can be transmitted to user equipment coupled to the serving access point to facilitate cell reselection. In one example, the per category cell reselection parameters reduce operational costs associated with processing and transmission of system parameters.

Claims

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

determining parameter data indicative of a common parameter associated with access point devices that are determined to belong to a common category, and

facilitating a transmission of the parameter data to a user equipment to facilitate cell reselection associated with the user equipment.

2. The system of claim 1, wherein the common category is associated with a common cell type associated with the access point devices.

3. The system of claim 2, wherein the common cell type comprise a metro cell type.

4. The system of claim 1, wherein the common category is associated with a common antenna configuration associated with the access point devices.

5. The system of claim 1, wherein the common category is associated with a common transmission power associated with the access point devices.

6. The system of claim 1, wherein the common category comprises a common classification of respective locations of the access point devices.

7. The system of claim 1, wherein the common category comprises a common capacity of the access point devices.

8. The system of claim 1, wherein the common parameter comprises an offset value that is employable to bias the user equipment to connect to an access point device of the access point devices.

9. A method, comprising:

determining, by a system comprising a processor, profile data employable to categorize access point devices;

assigning, by the system, first parameter data to a first group of the access point devices that is determined to be associated with a first category; and

assigning, by the system, second parameter data to a second group of the access point devices that is determined to be associated with a second category, wherein the assigning comprises assigning the first parameter data and the second parameter data to be employable to instruct a user equipment to facilitate cell reselection.

10. The method of claim 9, wherein the assigning the first parameter data comprises assigning a first offset value, wherein the assigning the second parameter data comprises assigning a second offset value, and wherein the first offset value and the second offset value are utilized to bias the user equipment to connect to one of the access point devices.

11. The method of claim 10, further comprising:

based on the profile data, determining, that the first group of the access point devices are categorized as metro cells and the second group of the access point devices are categorized as macro cells.

12. The method of claim 11, wherein the assigning the first offset value comprises assigning the first offset value that is lower than the second offset value.

13. The method of claim 9, wherein the determining comprises receiving the profile data via a communication link that employs an access point-to-access point signaling protocol.

14. The method of claim 9, wherein the determining comprises receiving the profile data via a network management device.
