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:

identifying at least one other network service application being able to transmit at least one packet at an event time of a packet transmission schedule of a first network service application;

adjusting a packet transmission schedule of the identified at least one other network service application to be synchronized with the packet transmission schedule of the first network service application; and

transmitting at least one packet of the first network service application according to the packet transmission schedule of the first network service application and transmitting at least one packet of the at least one other network service application according to the synchronized packet transmission schedule of the at least one other network service application,

wherein the identified at least one other network service application comprises a client program of a push data delivery service.

2. The method of claim 1, wherein the identifying of the at least one other network service application comprises determining the identified at least one other network service application having an adjustable packet transmission occasion to be the network service application having an adjustable packet transmission schedule.

3. The method of claim 2, wherein the client program of the push data delivery service 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 packet transmission schedule of the identified at least one other network service application comprises moving up the packet transmission schedule of the identified at least one other network service application to the packet transmission schedule of the first network service application.

5. The method of claim 4, wherein the adjusting of the packet transmission schedule of the identified at least one other network service application comprises skipping, when the identified at least one other network service application is a polling application, the packet transmission schedule of the identified at least one other network service application to synchronize the packet transmission schedule of the first network service application.

6. The method of claim 1, further comprising transmitting, when the identified at least one other network service application having an adjustable packet transmission schedule does not exist, only at least one packet of the first network service application.

7. The method of claim 1, further comprising switching, after the transmitting of the at least one packet of the first network service application, to an idle mode for minimizing consumption of electric current by the mobile terminal.

8. The method of claim 1, wherein the adjusting of the packet transmission schedule of the identified at least one other network service application comprises at least one of configuring two packet transmission schedules to be identical to each other, configuring at least one event time of each of the two packet transmission schedules to be identical to each other, and configuring a period of one packet transmission schedule to be a multiple of a period of another packet transmission schedule.

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

a control unit configured to identify at least one other network service application being able to transmit one or more packets at an event time of a packet transmission schedule of a first network service application, and to adjust a packet transmission schedule of the identified at least one other network service application to be synchronized with the packet transmission schedule of the first network service application; and

a radio communication unit configured to transmit at least one packet of the first network service application according to the packet transmission schedule of the first network service application and to transmit at least one packet of the at least one other network service application according to the synchronized packet transmission schedule of the at least one other network service application,

wherein the identified at least one other network service application comprises a client program of a push data delivery service.

10. The apparatus of claim 9, further comprising a scheduler configured to determine the identified at least one other network service application having an adjustable packet transmission occasion to be the identified at least one other network service application having an adjustable packet transmission schedule.

11. The apparatus of claim 10, wherein the client program of the push data delivery service is a push application which periodically transmits a keep-alive packet for maintaining a connection to a server.

12. The apparatus of claim 11, wherein the scheduler is further configured to move up the packet transmission schedule of the identified at least one other network service application to the packet transmission schedule of the first network service application.

13. The apparatus of claim 12, wherein the scheduler is further configured to skip, when the identified at least one other network service application is a polling application, the packet transmission schedule of the identified at least one other network service application to synchronize the packet transmission schedule of the first network service application.

14. The apparatus of claim 10, wherein the scheduler is further configured to control the radio communication unit to transmit, when the identified at least one other network service application does not exist, only the packet scheduled to be transmitted at the current time.

15. The apparatus of claim 9, wherein the control unit wakes up, at a time of a packet transmission occasion, from an idle mode for conserving electric current.

16. The apparatus of claim 9, wherein the control unit is further configured to control at least one of configuring two packet transmission schedules to be identical to each other, configuring at least one event time of each the two packet transmission schedules to be identical to each other, and configuring a period of one packet transmission schedule to be multiple of a period of another packet transmission schedule.
