Abstract

Provided is a method for receiving a notification indicating a completion of a network re-entry procedure by a Base Station (BS) in a communication system. The method includes transmitting, to a Mobile Station (MS), a RaNGing ReSPonse (RNG-RSP) message including information indicating whether to omit any of processes or transmission of messages for performing a network re-entry procedure with the BS; and receiving, from the MS, a notification indicating the completion of the network re-entry procedure.

Claims

1. A method for receiving a notification indicating completion of a network re-entry procedure by a base station (BS) in a communication system, the method comprising the steps of:

transmitting, to a mobile station (MS), a Ranging Response (RNG-RSP) message including information indicating whether to omit any of processes or transmission of messages for performing a network re-entry procedure with the BS; and

receiving, from the MS, a notification indicating completion of the network re-entry procedure,

wherein the completion of the network re-entry procedure indicates that the MS receives, from the BS, the RNG-RSP message and completes the network re-entry procedure with the BS according to the information, and

wherein the step of receiving, from the MS, a notification indicating completion of the network re-entry procedure comprises receiving, from the MS, a bandwidth request header with a zero bandwidth request field.

2. The method of claim 1, wherein, if the information indicates possibility of omitting all of the processes or transmission of messages necessary for performing the network re-entry procedure, the MS ends completing the network re-entry procedure with the BS upon receipt of the RNG-RSP message from the BS.

3. The method of claim 1, wherein if the information indicates at least one of the processes or transmission of messages is necessary for performing the network re-entry procedure, the MS notifies the completion of the network re-entry procedure to the BS after completing the at least one of the processes or transmission of messages necessary for performing the network re-entry procedure indicated in the information.

4. The method of claim 1, wherein if the information indicates at least one of the processes or transmission of messages is necessary for performing the network re-entry procedure, the MS ends completing the network re-entry procedure with a BS upon receipt of an unsolicited registration response (REG-RSP) message from the BS.

5. A system for receiving a notification indicating completion of a network re-entry procedure in a communication system, the system comprising:

a base station (BS) for transmitting, to a mobile station (MS), a Ranging Response (RNG-RSP) message including information indicating whether to omit any of processes or transmission of messages for performing a network re-entry procedure with the BS, and receiving, from the MS, a notification indicating completion of the network re-entry procedure,

wherein the completion of the network re-entry procedure indicates that the MS receives, from the BS. the RNG-RSP message and completes the network re-entry procedure with the BS according to the information, and

wherein the receiving, from the MS, a notification indicating completion of the network re-entry procedure comprises receiving, from the MS, a bandwidth request header with a zero bandwidth request field.

6. The system of claim 5, wherein, if the information indicates possibility of omitting all of the processes or transmission of messages necessary for performing the network re-entry procedure, the MS ends completing the network re-entry procedure with the BS upon receipt of the RNG-RSP message from the BS.

7. The system of claim 5, wherein if the information indicates at least one of the processes or transmission of messages is necessary for performing the network re-entry procedure, the MS notifies the completion of the network re-entry procedure to the BS after completing the at least one of the processes or transmission of messages necessary for performing the network re-entry procedure indicated in the information.

8. The system of claim 5, wherein if the information indicates at least one of the processes or transmission of messages is necessary for performing the network re-entry procedure, the MS ends completing the network re-entry procedure with a BS upon receipt of an unsolicited registration response (REG-RSP) message from the BS.
