Abstract

The present disclosure relates to an apparatus and a method for controlling Transmission Control Protocol (TCP) connection close to improve a battery life time of a client such as a smart phone in a wireless communication system are provided. A method of operating a client in a wireless communication system includes determining a data transfer inactivity time of at least one of TCP connections, and closing the at least one of TCP connections at the data transfer inactivity time.

Claims

1-24. -24. (canceled)

25. A method of operating a client in a wireless communication system, comprising:

identifying a first transmission control protocol (TCP) connection of which close is initiated by a server; and

closing the first TCP connection in response to an initiation of a process on a second TCP connection.

26. The method of claim 25, wherein the process on the second TCP connection comprises at least one of a connection, a closure and a transmitting and/or receiving operation of a data packet for the second TCP connection.

27. The method of claim 25, wherein the identifying of the first TCP connection comprises:

identifying the first TCP connection in response to a close message received from the server.

28. The method of claim 25, wherein a guard time period of the first TCP connection is greater than a predetermined reference time.

29. The method of claim 25, wherein a guard time period of the first TCP connection is not greater than a predetermined reference time, further comprising:

closing the first TCP connection at the end of the guard time period.

30. The method of claim 28, wherein the guard time period is determined based on a first time period and a second time period, and

wherein:

the first time period is a period of time from a transmission time of a request to a reception time of a response to the request, and

the second time period is a period of time from the reception time of the response to a transmission time of a next request.

31. The method of claim 28, wherein the guard time period is ahead of a server-initiated first TCP connection close time.

32. The method of claim 31, wherein the server-initiated first TCP connection close is performed in response to a message indicating a close of the first TCP connection received from the server.

33. An apparatus of a client in a wireless communication system, comprising:

a controller configured to;

identify a first transmission control protocol (TCP) connection of which close is initiated by a server, and

close the first TCP connection in response to an initiation of a process on a second TCP connection.

34. The apparatus of claim 33, wherein the process on the second TCP connection comprises at least one of a connection, a closure and a transmitting and/or receiving operation of a data packet for the second TCP connection.

35. The apparatus of claim 33, wherein the controller is further configured to identify the first TCP connection in response to a close message received from the server.

36. The apparatus of claim 33, wherein a guard time period of the first TCP connection is greater than a predetermined reference time.

37. The apparatus of claim 33, wherein a guard time period of the first TCP connection is not greater than a predetermined reference time, and

wherein the controller is further configured to close the first TCP connection at the end of the guard time period.

38. The apparatus of claim 36, wherein the guard time period is determined based on a first time period and a second time period, and

wherein:

the first time period is a period of time from a transmission time of a request to a reception time of a response to the request, and

the second time period is a period of time from the reception time of the response to a transmission time of a next request.

39. The apparatus of claim 36, wherein the guard time period is ahead of a server-initiated first TCP connection close time.

40. The apparatus of claim 39, wherein the server-initiated first TCP connection close is performed in response to a message indicating a close of the first TCP connection received from the server.
