Abstract

This disclosure relates to cell selection of a telecommunication device based on mobility management algorithms for idle mode cell selection routines and handover routines. The mobility management algorithm can utilize the BTS class of the infrastructure equipment to help determine cell selection. The BTS class of the infrastructure equipment can be used to determine the geographic size of the coverage area that the infrastructure equipment provides. These algorithms can be used to help handle mobility management for telecommunication device.

First claim

What is claimed is:

1. A computer-implemented method for determining an infrastructure equipment for handover in a wireless telecommunication network, the method comprising:
receiving a handover request from a telecommunication device;
identifying a source base transceiver station class associated with source infrastructure equipment based on a base transceiver station class identifier, the source infrastructure equipment corresponding to an existing communication channel with the telecommunication device;
identifying at least one target infrastructure equipment available for handover of the telecommunication device;
identifying a base transceiver station class associated with the at least one available target infrastructure equipment, each of the at least one available target infrastructure equipment having a base transceiver station class identifier, wherein each base transceiver station class identifier has a weighted value based, at least in part, on a geographic coverage area associated with the base transceiver station class;
determining a movement speed of the telecommunication device;
based on a determination that the movement speed of the telecommunication device exceeds a movement speed threshold, adjusting the weighted values of the base transceiver station class identifiers based, at least in part, on the movement speed of the telecommunications device; and
processing the handover request based, at least in part, on the adjusted weighted values associated with the base transceiver station class identifiers of the source infrastructure equipment and the at least one available target infrastructure equipment.

2. The computer-implemented method of claim 1 , wherein the weighted value of the base transceiver station class identifier associated with a smaller geographic coverage area is greater than the weighted value of the base transceiver station class identifier associated with a larger geographic coverage area.

3. The computer-implemented method of claim 1 , wherein processing the handover request includes:
if the base transceiver station class identifier of the source infrastructure equipment is the same as the base transceiver station class identifier of the at least one available target infrastructure equipment, processing the handover request based on quality of service criteria associated with the source infrastructure equipment and the at least one available infrastructure equipment.

4. The computer-implemented method of claim 1 further comprising ranking the source infrastructure equipment and the at least one available infrastructure equipment according to the base transceiver station class identifier.

5. The computer-implemented method of claim 1 , wherein the base transceiver station class identifier comprises a first identifier and a second identifier, wherein the first identifier and the second identifier are associated with an infrastructure equipment characteristic.

6. The computer-implemented method of claim 5 , wherein the infrastructure equipment characteristics comprise one of infrastructure equipment class, power, data rate, or number of connected users.

7. The computer-implemented method of claim 1 further comprising determining a velocity vector of the telecommunication device.

8. The computer-implemented method of claim 7 , wherein the velocity vector is based, at least in part, on positioning data.

9. The computer-implemented method of claim 7 further comprising predicting movement of the telecommunication device based, at least in part, on the velocity vector, wherein processing the handover request is based, at least in part, on the predicted movement of the telecommunication device.

10. The computer-implemented method of claim 1 , wherein the movement speed is based, at least in part, on positioning data.

11. The computer-implemented method of claim 1 , weighting the base transceiver station class identifiers based, at least in part based, on preferences from the telecommunication device.

12. A non-transitory computer-readable medium having a computer-executable component for determining selection of a infrastructure equipment for handover in a wireless telecommunication network, the computer-executable component comprising:
a mobility management component operative to:
receive a handover request;
identify a first base transceiver station class associated with a first infrastructure equipment based on a base transceiver station class identifier, the first infrastructure equipment in communication with a telecommunication device;
identify at least one infrastructure equipment available for handover of the telecommunication device;
identify a base transceiver station class of at least one available infrastructure equipment, each of the at least one available infrastructure equipment having a base transceiver station class identifier, wherein each base transceiver station class identifier has a weighted value based, at least in part on a geographic coverage area associated with the base transceiver station class; and
based on a determination that a movement speed of the telecommunication device exceeds a movement seed threshold adjust the weighted values of the base transceiver station class identifiers based, at least in part, on the movement speed of the telecommunications device;
process the handover request based, at least in part, on the adjusted weighted values associated with the base transceiver station class identifiers of the first infrastructure equipment and the at least one available infrastructure equipment.

13. The computer-readable medium of claim 12 , wherein the weighted value of the base transceiver station class identifier associated with a smaller geographic coverage area is greater than the weighted value of the base transceiver station class identifier associated with a larger geographic coverage area.

14. The computer-readable medium of claim 12 , wherein the mobility management component is further operative to determine handover of the telecommunication device between infrastructure equipment based on quality of service criteria when the base transceiver station class identifier of the first infrastructure equipment is the same as the base transceiver station class identifier of the at least one available infrastructure equipment.

15. The computer-readable medium of claim 12 , wherein the base transceiver station class identifier comprises a first identifier and a second identifier, wherein the each identifier is associated with an infrastructure equipment characteristic.

16. The computer-readable medium of claim 15 , wherein the infrastructure equipment characteristics comprise one of infrastructure equipment class, power, data rate, and number of connected users.

17. A system for determining selection of an infrastructure equipment for handover in a wireless telecommunication network, the system comprising:
a computing device in communication with a switching center, the computing device comprising a mobility management component operative to:
receive control messages from infrastructure equipment, wherein each control messages comprises a base transceiver station class identifier;
identify a first base transceiver station class associated with a first infrastructure equipment based on a first base transceiver station class identifier, the first infrastructure equipment in communication with a telecommunication device;
identify at least one infrastructure equipment available for handover of the telecommunication device;
identify a base transceiver station class of the at least one available infrastruc
