Method and apparatus for load balancing in a wireless communication network
View Patent ↗A method, system, and apparatus for communication in wireless communication network having an Access Service Network-controller (ASN-controller) communicating with plurality of Base Stations (BSs). The method includes reading one or more reports of plurality of reports received from the plurality of BSs. The plurality of reports comprise spare capacity information of one or more BSs of the plurality of BSs. The method further includes generating one or more directions based on the one or more reports to perform load balancing.
1. A method of communicating in a wireless communication network, the method comprising:
reading at least one report of a plurality of reports received from a plurality of Base Stations (BSs) in the wireless communication network, the plurality of reports including spare capacity information of the plurality of BSs; and
generating at least one direction based on the reading of the at least one report and the spare capacity information of the plurality of BSs, the at least one direction providing instructions to offload one or more Mobile Stations (MSs) and to perform load balancing.
2. The method of claim 1 , wherein the at least one direction is generated in an ASN-controller in communication with the plurality of BSs in the wireless communication network.
3. The method of claim 1 further comprising initiating at least one instruction for at least one BS of the plurality of BS in response to generating the at least one direction.
4. The method of claim 3 , wherein the at least one instruction is initiated in an ASN-controller in communication with the plurality of BSs in the wireless communication network.
5. The method of claim 3 , wherein the at least one instruction is initiated in at least one BS of the plurality of BSs.
6. The method of claim 3 , wherein the at least one instruction includes at least one of:
number of Mobile Stations (MSs) for performing load balancing and at least one target BS selected from the plurality of BSs for a handover.
7. The method of claim 6 , wherein the load balancing is performed by executing handover of at least one MS to the at least one target BS based on the number of MSs.
8. The method of claim 6 , wherein the load balancing is performed by dropping at least one MS based on the number of MSs.
9. The method of claim 1 , wherein the plurality of reports are received in response to at least one request generated from at least one BS of the plurality of BSs.
10. The method of claim 1 , wherein the wireless communication network corresponds to a profile-c network architecture of a Worldwide Interoperability Microwave Access (WiMAX) communication network.
11. The method of claim 1 , wherein the communicating is performed in a manner consistent with a protocol according to one of a WiMAX communication network, a 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) network, a 3rd Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband (UMB) network, a Wireless Fidelity (WiFi) network or an Orthogonal Frequency Division Multiple Access (OFDMA) communication network having a backhaul link.
12. A system for communicating in a wireless communication network, the system comprising:
a reading module configured to read at least one report of a plurality of reports received from a plurality of BSs in the communication network, the plurality of reports including spare capacity information of the plurality of BSs; and
a directing module configured to generate at least one direction based on the at least one report read and the spare capacity information of the plurality of BSs, the at least one direction providing instructions to offload one or more Mobile Stations (MSs) and to perform load balancing.
13. The system of claim 12 , wherein the system further comprises an initiating module configured to initiate at least one instruction for at least one BS of the plurality of BS in response to generating the at least one direction.
14. The system of claim 13 , wherein the at least one instruction includes at least one of a number of Mobile Stations (MSs) for performing the load balancing and at least one target BS selected from the plurality of BSs for a handover.
15. The system of claim 14 , wherein the system further comprises a load balancing module configured to perform at least one of:
executing handover of at least one MS to the at least one target BS based on the number of MSs; and
dropping at least one MS based on the number of MSs.
16. An apparatus in a wireless communication network, the apparatus comprising:
a processor configured to:
read at least one report of a plurality of reports received from a plurality of BSs, the plurality of reports including spare capacity information of the plurality of BSs;
generate at least one direction based on the at least one report read and the spare capacity information of the plurality of BSs, the at least one direction providing instructions to offload one or more Mobile Stations (MSs) and to perform load balancing; and
a transceiver configured to communicate the at least one direction to at least one BS of the plurality of BSs.
17. The apparatus of claim 16 , wherein the processor is further configured to initiate at least one instruction for the at least one BS of the plurality of BS in response to generating the at least one direction.
18. The apparatus of claim 16 , wherein the apparatus is an ASN-controller.
19. The apparatus of claim 16 , wherein the apparatus is a BS selected from the plurality of BSs.
20. The method of claim 1 , wherein the spare capacity information includes a number of MSs served by a respective BS of the plurality of BSs.
