Abstract

A method for communicating with a mobile station is presented. The method includes transmitting a first radio block to the mobile station. The first radio block including an indication instructing the mobile station to enter a DTR mode. Before receiving an indication of whether the mobile station is in DTR mode, the method includes retransmitting to the mobile station at least one of the first radio block and a radio block previously transmitted to the mobile station using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode.

Claims

1. A method for a mobile station configured to communicate with a network, comprising:

receiving a first radio block, of a plurality of radio blocks, having a block sequence number, the first radio block including an indication instructing the mobile station to enter a dynamic timeslot reduction (DTR) mode;

after receiving the first radio block, receiving a first poll message; and

if all radio blocks, of the plurality of radio blocks, having block sequence numbers less than or equal to the block sequence number of the first radio block have been successfully received from the network, ignoring the first poll message and entering the DTR mode.

2. A method according to claim 1, wherein the first poll message is received from the network using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode.

3. A method according to claim 2, wherein the first radio block includes a second poll message, and further comprising responding to the second poll message included in the first radio block.

4. A method according to claim 1, wherein the first radio block includes a second poll message, and further comprising responding to the second poll message included in the first radio block.

5. A method according to claims 1, wherein, when in the DTR mode, the mobile station monitors timeslots identified in the first radio block.

6. A method for a network configured to communicate with a mobile station, the method comprising:

transmitting a first radio block to the mobile station, the first radio block including an indication instructing the mobile station to enter a dynamic timeslot reduction (DTR) mode; and

after transmitting the first radio block, transmitting a first poll message to the mobile station using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode.

7. A method according to claim 6, further comprising receiving a response to the first poll message;

and determining that the mobile station has not entered the DTR mode.

8. A method according to claims 7, further comprising:

after transmitting the first poll message, transmitting a second poll message using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode; and

if no response to the second poll message is received from the mobile station, determining that the mobile station has entered the DTR mode.

9. A method according to claims 8, wherein the indication instructing the mobile station to enter the DTR mode includes an identification of timeslots to be monitored by the mobile station in the DTR mode.

10. A method according to claims 7, wherein the indication instructing the mobile station to enter the DTR mode includes an identification of timeslots to be monitored by the mobile station in the DTR mode.

11. A method according to claims 6, further comprising:

after transmitting the first poll message, transmitting a second poll message using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode; and

if no response to the second poll message is received from the mobile station, determining that the mobile station has entered the DTR mode.

12. A method according to claims 11, wherein the indication instructing the mobile station to enter the DTR mode includes an identification of timeslots to be monitored by the mobile station in the DTR mode.

13. A method according to claim 6, including, when no response to the first poll message is received from the mobile station, determining that the mobile station has entered the DTR mode.

14. A method according to claim 6, further comprising, before receiving an indication of whether the mobile station is in the DTR mode, retransmitting to the mobile station at least one of the first radio block or a radio block previously transmitted to the mobile station using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode.

15. A method according to claim 14, wherein retransmitting to the mobile station the at least one of the first radio block or a radio block previously transmitted to the mobile station includes using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode.

16. A method according to claim 6, wherein the indication instructing the mobile station to enter the DTR mode includes an identification of timeslots to be monitored by the mobile station in the DTR mode.

17. A mobile station for use with a communications network, comprising:

a processor configured to;

receive a first radio block, of a plurality of radio blocks, having a block sequence number, the first radio block including an indication instructing the mobile station to enter a dynamic timeslot reduction (DTR) mode;

after receiving the first radio block, receive a first poll message; and

if all radio blocks, of the plurality of radio blocks, having block sequence numbers less than or equal to the block sequence number of the first radio block have been successfully received from the network, ignore the first poll message and entering the DTR mode.

18. A tangible article of manufacture storing machine readable instructions which, when executed, cause a machine to:

receive a first radio block, of a plurality of radio blocks, having a block sequence number, the first radio block including an indication instructing the mobile station to enter a dynamic timeslot reduction (DTR) mode;

after receiving the first radio block, receive a first poll message; and

if all radio blocks, of the plurality of radio blocks, having block sequence numbers less than or equal to the block sequence number of the first radio block have been successfully received from the network, ignore the first poll message and entering the DTR mode.
