Abstract

Methods, systems, and apparatuses (including, but not limited to, User Equipment (UE) and Base Stations) for a UE to control a packet header compression function in a communication system are described. In one method, if a predetermined condition is satisfied while the packet header compression function is enabled, the UE transmits a request for disabling the packet header compression function to a Base Station (BS), and, if a response is received from the BS, the UE disables the packet header compression function.

First claim

What is claimed is:

1 . A method for a User Equipment (UE) to control packet header compression function in a communication system, comprising:
transmitting a request for disabling the packet header compression function to a Base Station (BS), if a predetermined condition is satisfied while the packet header compression function is enabled; and determining whether to discontinue execution of the packet header compression function according to whether a response to the request is received from the BS.

2 . The method of claim 1 , wherein if the response to the request is not received from the BS, the execution of the packet header compression function is continued.

3 . The method of claim 1 , wherein if the response to the request is received from the BS, the execution of the packet header compression function is discontinued.

4 . The method of claim 1 , wherein the predetermined condition is based on at least one of loss of context of the packet header compression function, a channel state, and a remaining battery power amount of the UE.

5 . The method of claim 1 , wherein the request for disabling the packet header compression function is included in a feedback message concerning the packet header compression function.

6 . A method for controlling a packet header compression function of a User Equipment (UE) in a communication system, the method comprising:
upon receipt of a request for disabling a currently-enabled packet header compression function from a UE, determining whether to accept the request; and transmitting a response indicating acceptance of the request to the UE, if it is determined to accept the request.

7 . The method of claim 6 , wherein if the request is not accepted, the execution of the packet header compression function is continued.

8 . The method of claim 6 , wherein if the response is transmitted, the execution of the packet header compression function is discontinued.

9 . The method of claim 6 , wherein the UE transmits the request if the UE satisfies a predetermined condition, and the predetermined condition is based on at least one of loss of context of the packet header compression function, a channel state, and a remaining battery power amount of the UE.

10 . The method of claim 6 , wherein the request for disabling the packet header compression function is included in a feedback message concerning the currently-enabled packet header compression function.

11 . A User Equipment (UE) which controls a packet header compression function in a communication system, the apparatus comprising:
a transceiver; and a controller which, if a predetermined condition is satisfied while the packet header compression function is enabled, controls the transceiver to transmit a request for disabling the packet header compression function to a Base Station (BS), and determines whether to discontinue execution of the packet header compression function according to whether a response to the request is received from the BS.

12 . The apparatus of claim 11 , wherein if the response to the request is not received from the BS, the controller continues the execution of the packet header compression function.

13 . The apparatus of claim 11 , wherein if the response to the request is received from the BS, the controller discontinues the execution of the packet header compression function.

14 . The UE of claim 11 , wherein the predetermined condition is based on at least one of loss of context of the packet header compression function, a channel state, and a remaining battery power amount of the UE.

15 . The UE of claim 13 , wherein the request for disabling the packet header compression function is transmitted in a feedback message concerning the packet header compression function.

16 . A Base Station (BS) to allow a User Equipment (UE) to control a packet header compression function in a communication system, comprising:
a transceiver; and a controller which, upon receipt of a request for disabling a currently-enabled packet header compression function from a UE during execution of the packet header compression function, determines whether to accept the request, and controls the transceiver to transmit a response indicating acceptance of the request to the UE, if it is determined to accept the request.

17 . The BS of claim 16 , wherein if the request is not accepted, the response is not transmitted and the packet header compression function continues.

18 . The BS of claim 16 , wherein if the response is transmitted, the packet header compression function is discontinued.

19 . The BS of claim 16 , wherein the UE transmits the request when a predetermined condition of the UE is satisfied, and the predetermined condition is based on at least one of loss of context of the packet header compression function, a channel state, and a remaining battery power amount of the UE.

20 . The BS of claim 16 , wherein the request for disabling the packet header compression function is included in a feedback message concerning the packet header compression function.
