Abstract

A method for reducing UE power consumption under a communication network is disclosed. The key principle of the method is an algorithm to force a RRC connection between a communication network and a UE to be released when mail client completes the synchronization process and the UE has no activity. The method includes steps of: (a) checking if a user inactive event occurs in the UE; (b) sending a signaling connection release message on a dedicated control channel from the UE.

Claims

1. A method for reducing user equipment (UE) power consumption under a communication network, comprising:

checking if a user inactive event occurs in a UE; and

sending a signaling connection release message from the UE if the user inactive event occurs.

2. The method according to the claim 1, wherein, the UE power consumption being in a CELL_DCH state, in a CELL_FACH state, or in the CELL_DCH and CELL_FACH state.

3. The method according to the claim 1, wherein, the signaling connection release message being for Packet Switching (PS) domain to the communication network.

4. The method according to the claim 1, further comprising:

receiving a RRC connection release message by the UE;

releasing a RRC connection of the UE after receiving the RRC connection release message by the UE; and

making the UE enter an IDLE state, a CELL_PCH or an URA_PCH after releasing the RRC connection by the UE.

5. The method according to the claim 4, further comprising:

receiving the signaling connection release message by the communication network; and

sending a RRC connection release message from the communication network.

6. The method according to the claim 1, wherein, the user inactive event in the UE including an event of screen off, an event of data guard time expiration or both of these two events.

7. The method according to the claim 1, wherein, the communication network being a WCDMA network with mail service.

8. The method according to the claim 7, wherein, the WCDMA network with mail service being a WCDMA network with real-time mail service.

9. The method according to the claim 1, wherein, the user inactive event in the UE being defined by a software program which can be executed in the UE.

10. A method for reducing UE power consumption in a CELL_FACH or CELL_DCH state under a WCDMA network with mail service, comprising:

checking if a user inactive event occurs in a UE; and

sending a signaling connection release message from the UE if the user inactive event occurs;

wherein, the signaling connection release message being for Packet Switching (PS) domain to the communication network, and the user inactive event in the UE being defined by a software program which can be executed in the UE.

11. The method according to the claim 10, further comprising:

receiving a RRC connection release message by the UE;

releasing a RRC connection of the UE after receiving the RRC connection release message by the UE; and

making the UE enter an IDLE state, a CELL_PCH or an URA_PCH after releasing the RRC connection by the UE.

12. The method according to the claim 11, further comprising:

receiving the signaling connection release message by the WCDMA network; and

sending a RRC connection release message on the dedicated control channel from the WCDMA network.

13. The method according to the claim 10, wherein, the user inactive event including an event of screen off, an event of data guard time expiration or both of these two events.

14. The method according to the claim 10, wherein, the WCDMA network with mail service being a WCDMA network with real-time mail service.
