Abstract

The present invention relates to a method and a system for dynamically reducing a number of RF technologies being used for processing at least one broadcast service for a plurality of mobile stations in a wireless communication network. The method comprises determining an RF technology being used by each mobile station. At least one of a plurality of predefined parameters is evaluated if at least two mobile stations of the plurality of mobile stations are using different RF technologies. Further, at least one mobile station of the plurality of mobile stations is switched to a preferred RF technology in response to evaluating the at least one of a plurality of predefined parameters.

Claims

1. A method for dynamically reducing a number of RF technologies being used for processing at least one broadcast service for a plurality of mobile stations in a wireless communication network, the method comprising:

determining an RF technology being used by each mobile station;

evaluating at least one of a plurality of predefined parameters associated with a mobile station of the plurality of mobile stations if at least two mobile stations of the plurality of mobile stations are using different RF technologies; and

switching at least one mobile station of the plurality of mobile stations to a preferred RF technology in response to evaluating the at least one of a plurality of predefined parameters.

2. The method for claim 1, wherein the plurality of predefined parameters comprises at least one of calendar schedule information, presence status, historical traffic statistics, a buddy list, call reservation information, RF technology compatibility, relative location of the mobile station and movement of the mobile station.

3. The method of claim 1, wherein the preferred RF technology is selected based on an RF condition associated with the number of RF technologies.

4. The method of claim 1, wherein the switching step is performed preemptively before beginning the at least one broadcast service.

5. The method of claim 1, wherein the switching step is performed during the at least one broadcast service.

6. A method for facilitating at least one mobile station of a plurality of mobile stations in accessing a broadcast service in a wireless communication network, the method comprising:

scanning a calendar schedule corresponding to each mobile station of the plurality of mobile stations to determine at least one scheduled event for the broadcast service;

obtaining location information corresponding to each mobile station belonging to a first subset of the plurality of mobile stations, wherein the first subset of the plurality of mobile stations comprises mobile stations which are prospective participants of the broadcast service;

determining an RF technology being used by each mobile station belonging to the first subset of the plurality of mobile stations; and

registering at least one mobile set belonging to the first subset of the plurality of mobile stations to a preferred RF technology.

7. An apparatus comprising:

a transceiver; and

a processor adaptively coupled to the transceiver and configured to;

determine an RF technology of the plurality of RF technologies used by each mobile station of a plurality of mobile stations operating in a wireless communication network;

evaluate at least one of a plurality of predefined parameters, if at least two mobile stations of the plurality of mobile stations are using different RF technologies; and

broadcast a switch message to at least one mobile station of the plurality of mobile stations instructing the at least one mobile station to switch to a preferred RF technology for accessing a broadcast service.

8. The apparatus of claim 8, wherein the transceiver is further configured to receive at least one of calendar schedule information, presence status, historical traffic statistics, a buddy list, call reservation information, RF technology compatibility, relative location of the mobile station and movement of the mobile station.

9. The apparatus of claim 8, wherein the transceiver is further configured to obtain an RF technology compatibility corresponding to the preferred RF technology for the at least one mobile station of the plurality of mobile stations.

10. A mobile station (MS) comprising:

a transceiver;

a processor, adaptively coupled to the transceiver and configured to;

send at least one of a calendar schedule information and a presence status corresponding to the MS to a base transceiver station;

determine an RF technology compatibility of the MS with a plurality of RF technologies; and

receive a switch message instructing the MS to switch to a preferred RF technology, wherein the plurality of RF technologies includes the preferred RF technology.

11. The mobile station of claim 12, wherein the processor is configured to switch to the preferred RF technology when the processor receives the switch message.
