Abstract

A radio access network has a reverse link frequency band for receiving signals from mobile stations and has first and second forward link frequency bands for transmitting signals to mobile stations. The second forward link frequency band has a greater frequency bandwidth than the first forward link frequency band and occupies a different part of the radio frequency spectrum. For certain types of communication sessions, such as voice and low-speed data, the reverse link frequency band and the first forward link frequency band are used. For other types of communication sessions, such as high-speed data and streaming video, the reverse link frequency band and the second forward link frequency band are used.

Claims

1. A method of allocating radio resources for wireless communication, said method comprising:

receiving a request to establish a communication session between a mobile station and a radio access network for a user of said mobile station, said communication session having a session type; and

in response to said request, selecting a working frequency division duplex (FDD) configuration from among at least a first FDD configuration and a second FDD configuration based on at least a service level subscription of said user, said first FDD configuration including a reverse link frequency band and a first forward link frequency band, said second FDD configuration including said reverse link frequency band and a second forward link frequency band, said first forward link frequency band including traffic channels with a first frequency bandwidth, said second forward link frequency band including traffic channels with a second frequency bandwidth, wherein said first and second forward link frequency bands are non-overlapping and said second frequency bandwidth is greater than said first frequency bandwidth.

2. The method claim 1, wherein said working FDD configuration is selected based on at least said service level subscription of said user and said session type.

3. The method of claim 2, wherein said first FDD configuration is selected as said working FDD configuration if said session type corresponds to a voice session or low speed data session and said second FDD configuration is selected as said working FDD configuration if said session type corresponds to a high speed data session or streaming video session.

4. The method of claim 1, wherein said request includes a bandwidth preference.

5. The method of claim 4, wherein said working FDD configuration is selected based on at least said service level subscription of said user and said bandwidth preference.

6. The method of claim 5, wherein said first FDD configuration is selected as said working FDD configuration if said bandwidth preference is a low-bandwidth preference and said second FDD configuration is selected as said working FDD configuration is said bandwidth preference is a high-bandwidth preference.

7. The method of claim 4, further comprising:

said mobile station selecting said bandwidth preference from among at least a low-bandwidth preference and a high-bandwidth preference based on a service profile.

8. The method of claim 7, wherein said low-bandwidth preference is selected if said session type corresponds to a voice session or low speed data session and said second high-bandwidth preference is selected if said session type corresponds to a high speed data session or streaming video session.

9. The method of claim 1, further comprising:

selecting said second FDD configuration as said working FDD configuration;

selecting a reverse traffic channel in said reverse link frequency band; and

selecting a forward traffic channel in said second forward link frequency band.

10. The method of claim 9, wherein said forward traffic channel has a greater frequency bandwidth than said reverse traffic channel.

11. The method of claim 9, wherein said forward traffic channel has a higher carrier frequency than said reverse traffic channel.

12. The method of claim 9, wherein said forward traffic channel is a time division multiplexed channel and said reverse traffic channel is a code division multiplexed channel.

13. The method of claim 1, wherein said first forward link frequency band provides wireless coverage in a first wireless coverage area and said second forward link frequency band provides wireless coverage in a second wireless coverage area, said second wireless coverage area being larger than said first wireless coverage area.
