Abstract

Systems and techniques are disclosed relating to communications. The systems and techniques include an input device, generating a time period in response to a broadcast channel selection from the input device, generating a request to register the broadcast channel if the time period ends before receiving a second broadcast channel selection, and transmitting the request to an access network. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Claims

1. A wireless subscriber station for use with an access network, the wireless subscriber station comprising:

an input device;

a processor including;

a guard timer configured to start in response to a first selection of a first broadcast channel and to restart in response to a second selection of a second broadcast channel made before the guard timer expires from the first selection, the second broadcast channel being different than the first broadcast channel, both the first selection and the second selection being made at the wireless subscriber station from the input device;

a registration timer configured to generate a first request to register the first broadcast channel in response to expiration of the registration timer started upon expiration of the guard timer, if the guard timer expires before being restarted by the second selection; and

an analog front end configured to transmit the first request to the access network and to select a paging channel to monitor, the paging channel identified according to the first request and specific to the first broadcast channel.

2. The wireless subscriber station of claim 1, wherein:

the processor is further configured to generate a second request to re-register the first broadcast channel if the first broadcast channel remains selected after the registration timer expires; and

the analog front end is further configured to transmit the second request to the access network.

3. The wireless subscriber station of claim 1, wherein the processor is further configured to maintain a list of viewed broadcast channels.

4. The wireless subscriber station of claim 3, wherein the processor is further configured to store the list of viewed broadcast channels.

5. The wireless subscriber station of claim 4, wherein the processor is further configured to forward the list to a base station that is serving the wireless subscriber station.

6. A method of wireless communications, comprising:

starting a guard timer in response to a first selection of a first broadcast channel and restarting the guard timer in response to a second selection of a second broadcast channel made before the guard timer expires from the first selection, the second broadcast channel being different than the first broadcast channel, both the first selection and the second selection being made at a wireless subscriber station from an input device of the wireless subscriber station;

generating a first request to register the first broadcast channel in response to expiration of a registration timer started upon expiration of the guard timer, and transmitting the first request to an access network if the guard timer expires before receiving the second selection; and

selecting a paging channel to monitor identified according to the first request and specific to the first broadcast channel.

7. The method of wireless communications of claim 6, further comprising generating a second request to re-register the first broadcast channel and transmitting the second request to the access network if the first broadcast channel remains selected after the registration timer expires.

8. The method of claim 6, further comprising maintaining a list of viewed broadcast channels.

9. The method of claim 8, further comprising storing the list of viewed broadcast channels.

10. The method of claim 9, further comprising forwarding the list to a base station that is serving the wireless subscriber station.

11. A wireless subscriber station for use with an access network, the wireless subscriber station comprising:

means for inputting a broadcast channel selection;

means for starting a guard timer in response to a first selection of a first broadcast channel and restarting the guard timer in response to a second selection of a second broadcast channel made before the guard timer expires from the first selection, the second broadcast channel being different than the first broadcast channel, both the first selection and the second selection being made at the wireless subscriber station;

means for generating a first request to register the first broadcast channel in response to expiration of a registration timer started upon expiration of the guard timer, and transmitting the first request to an access network if the guard timer expires before receiving the second selection; and

means for selecting a paging channel to monitor identified according to the first request and specific to the first broadcast channel.

12. The wireless subscriber station of claim 11, further comprising means for generating a second request to re-register the first broadcast channel and transmitting the second request to the access network if the first broadcast channel remains selected after the registration timer expires.

13. The wireless subscriber station of claim 11, further comprising means for maintaining a list of viewed broadcast channels.

14. The wireless subscriber station of claim 13, further comprising means for storing the list of viewed broadcast channels.

15. The wireless subscriber station of claim 14, further comprising means for forwarding the list to a base station that is serving the wireless subscriber station.

16. A computer-readable storage device encoded with instructions executable by a processor to perform a method of wireless communications, the method comprising:

starting a guard timer in response to a first selection of a first broadcast channel and restarting the guard timer in response to a second selection of a second broadcast channel made before the guard timer expires from the first selection, the second broadcast channel being different than the first broadcast channel, both the first selection and the second selection being made at a wireless subscriber station from an input device of the wireless subscriber station;

generating a first request to register the first broadcast channel in response to expiration of a registration timer started upon expiration of the guard timer, and transmitting the first request to an access network if the guard timer expires before receiving the second selection; and

selecting a paging channel to monitor identified according to the first request and specific to the first broadcast channel.

17. The computer readable media of claim 16, wherein the method further comprises generating a second request to re-register the first broadcast channel and transmitting the second request to the access network if the first broadcast channel remains selected after the registration timer expires.

18. The computer readable media of claim 16, wherein the method further comprises maintaining a list of viewed broadcast channels.

19. The computer readable media of claim 18, wherein the method further comprises storing the list of viewed broadcast channels.

20. The computer readable media of claim 19, wherein the method further comprises forwarding the list to a base station that is serving the wireless subscriber station.
