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 communicating with a mobile station, comprising:

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; and

before receiving an indication of whether the mobile station is in DTR mode, 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.

2. The method of claim 1, wherein, when in the DTR mode, the mobile station monitors timeslots identified in the first radio block.

3. The method of claim 1, including, after transmitting the first radio block to the mobile station, transmitting a 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.

4. The method of claim 3, including, when no response to the poll message is received from the mobile station, determining that the mobile station has entered the DTR mode.

5. The method of claim 3, including, when a response to the poll message is received from the mobile station, determining that the mobile station has not entered the DTR mode.

6. A method for communicating with a mobile station, comprising:

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; and

before determining that the mobile station is in DTR mode, transmitting a 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. The method of claim 6, including, when no response to the poll message is received from the mobile station, determining that the mobile station has entered the DTR mode.

8. The method of claim 6, including, when a response to the poll message is received from the mobile station, determining that the mobile station has not entered the DTR mode.

9. The method of claim 6, wherein retransmitting to the mobile station the at least one of the first radio block and 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.

10. A method for communicating with a network, comprising:

receiving a first radio block, the first radio block including an indication instructing a mobile station to enter a DTR mode and having a block sequence number;

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

when all 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 poll message; and

entering the DTR mode.

11. The method of claim 10, wherein the 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.

12. The method of claim 10, wherein the first radio block includes a second poll message, and including responding to the second poll message included in the first radio block.

13. A network component, comprising:

a processor, the processor being configured to;

transmit a first radio block to a mobile station, the first radio block including an indication instructing the mobile station to enter a DTR mode; and

before receiving an indication of whether the mobile station is in DTR mode, retransmit 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.

14. The network component of claim 13, wherein, when in the DTR mode, the mobile station monitors timeslots identified in the first radio block.

15. The network component of claim 13, wherein the processor is configured to, after transmitting the first radio block to the mobile station, transmit a 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.

16. The network component of claim 15, including, when no response to the poll message is received from the mobile station, the processor is configured to determine that the mobile station has entered the DTR mode.

17. The network component of claim 15, including, when a response to the poll message is received from the mobile station, the processor is configured to determine that the mobile station has not entered the DTR mode.

18. A mobile station, comprising:

a processor, the processor being configured to;

receive a first radio block, the first radio block including an indication instructing a mobile station to enter a DTR mode and having a block sequence number;

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

when all 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 a network;

ignore the poll message; and

enter the DTR mode.

19. The mobile station of claim 18, wherein the 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.

20. The mobile station of claim 18, wherein the first radio block includes a second poll message, and the processor is configured to respond to the second poll message included in the first radio block.
