Abstract

A method and an apparatus for transmitting a packet used in establishing or maintaining a connection with a server are provided. The method includes determining, when a current time is a packet transmission of at least one network service application of the mobile terminal, whether at least one other network service application having an adjustable packet transmission schedule with a packet transmission after the current time exists, adjusting, when the at least one other network service application exists, the adjustable packet transmission schedule to synchronize the packet transmission occasions of the at least one network service application with the at least one other network service application, and simultaneously transmitting a packet of the network service application having the packet transmission occasion at the current time and a packet of the at least one other network service application of which packet transmission schedule is adjusted.

Claims

1. A packet transmission method of a mobile terminal, the method comprising:

determining, when a current time is a packet transmission occasion of at least one network service application of the mobile terminal, whether at least one other network service application having an adjustable packet transmission schedule with a packet transmission occasion after the current time exists;

adjusting, when the at least one other network service application having the adjustable packet transmission schedule with the packet transmission occasion after the current time exists, the adjustable packet transmission schedule of the at least one other network service application to synchronize the packet transmission occasions of the at least one network service application with the at least one other network service application; and

simultaneously transmitting a packet of the network service application having the packet transmission occasion at the current time and a packet of the at least one other network service application of which packet transmission schedule is adjusted.

2. The method of claim 1, wherein the determining of whether the at least one other network service application having the adjustable packet transmission schedule with the packet transmission occasion after the current time exists comprises determining that the network service application having adjustable packet transmission occasion to be the network service application having the adjustable packet transmission schedule.

3. The method of claim 2, wherein the network service application having the adjustable packet transmission occasions is a push application which periodically transmits a keep-alive packet for maintaining a connection to a server.

4. The method of claim 3, wherein the adjusting of the adjustable packet transmission schedule of the at least one other network service application comprises moving up, when the network service application having the packet transmission occasion after the current time is the push application, the packet transmission occasion after the current time to the current time.

5. The method of claim 4, wherein the adjusting of the adjustable packet transmission schedule of the at least one other network service application comprises skipping, when the network service application having the packet transmission occasion after the current time is a polling application, adjustment of the packet transmission occasion after the current time.

6. The method of claim 1, further comprising transmitting, when no other network service application having the adjustable packet transmission schedule exists, only a packet scheduled to be transmitted at the current time.

7. The method of claim 1, further comprising switching, after the simultaneously transmitting of the packet of the network service application having the packet transmission occasion at the current time and the packet of the at least one other network service application of which packet transmission schedule is adjusted, to an idle mode for minimizing consumption of electric current by the mobile terminal.

8. A packet transmission apparatus of a mobile terminal, the apparatus comprising:

a control unit which selects, when a current time is a packet transmission occasion of at least one network service application, at least one other network service application and adjusts a packet transmission schedule of the selected at least one other network service application; and

a radio communication unit which simultaneously transmits a packet of the network service application and a packet of the selected at least one other network service application.

9. The apparatus of claim 8, where the control unit comprises:

a scheduler which determines, when the current time is a packet transmission occasion of at least one network service application, whether any other network service application having an adjustable packet transmission schedule with a succeeding packet transmission occasion exists and adjusts, when the any other network service application having the adjustable packet transmission schedule exists, the packet transmission schedule of the existing any other network service application to synchronize the packet transmission occasions of the at least one network service application with the existing any other network service application; and

a packet transmission controller which controls simultaneous transmitting of the packets of the at least one network service application and the existing any other network service application.

10. The apparatus of claim 9, wherein the scheduler determines the existing any other network service application having the adjustable packet transmission occasion to be the any other network service application having the adjustable packet transmission schedule.

11. The apparatus of claim 10, wherein the scheduler determines a push application which periodically transmits a keep-alive packet for maintaining a connection to a server as the existing any other network service application having the adjustable packet transmission occasions.

12. The apparatus of claim 11, wherein the scheduler moves up, when the existing any other network service application has a packet transmission occasion after the current time, the packet transmission occasion of the existing any other network service application to the current time.

13. The apparatus of claim 12, wherein the scheduler skips, when the scheduler determines a polling application to be the existing any other network service application having a packet transmission occasion after the current time, adjustment of the packet transmission occasion after the current time.

14. The apparatus of claim 9, wherein the scheduler controls the packet transmission controller to transmit, when no other network service application having an adjustable packet transmission schedule exists, only the packet scheduled to be transmitted at the current time.

15. The apparatus of claim 8, wherein the control unit wakes up, at a time of the packet transmission occasion, from an idle mode for conserving electric current.
