Abstract

A method (200) and system (100) for supporting fast connection set-up in a communication network (110). The method can include the steps of - in a mobile station (114) that is capable of operating in at least two separate power saving modes, a first power saving mode and a second power saving mode, entering (212) an operational state associated with the second power saving mode and staying (214) in the first power saving mode. This process can enable the mobile station to avoid entry into the second power saving mode during the operational state. In the first power saving mode, the mobile station may remain registered with a communication network. In the second power saving mode, the mobile station may be de-registered from the communication network. The first power saving mode can be a sleep mode, and the second power saving mode can be an idle mode.

Claims

1. A method for supporting fast connection set-up in a communication network, comprising:

in a mobile station that is capable of operating in at least two separate power saving modes—

a first power saving mode and a second power saving mode—

entering an operational state associated with the second power saving mode; and

staying in the first power saving mode, thereby avoiding entry into the second power saving mode during the operational state, wherein in the first power saving mode, the mobile station remains registered with a communication network and in the second power saving mode, the mobile station is de-registered from the communication network.

2. The method according to claim 1, wherein the first power saving mode is a sleep mode and the second power saving mode is an idle mode.

3. The method according to claim 1, wherein the operational state comprises a state where no application is currently running on the mobile station.

4. The method according to claim 1, wherein the communication network is an 802.16e network.

5. The method according to claim 1, wherein staying in the first power saving mode further comprises staying in the first power saving mode based on predefined criteria.

6. The method according to claim 1, wherein the predefined criteria include a type of subscription for the mobile station, a time of day or the second power saving mode being incompatible with an application of the mobile station.

7. A mobile station that is capable of operating in a communication network and in at least two separate power saving modes, a first power saving mode and a second power saving mode, comprising:

a user interface for enabling operation of at least one application; and

a processor coupled to the user interface, wherein the processor is programmed to;

cause the mobile station to enter an operational state associated with the second power saving mode; and

cause the mobile station to stay in the first power saving mode, thereby avoiding entry into the second power saving mode during the operational state, wherein in the first power saving mode, the mobile station remains registered with a communication network and in the second power saving mode, the mobile station is de-registered from the communication network.

8. The mobile station according to claim 7 wherein the first power saving mode is a sleep mode and the second power saving mode is an idle mode.

9. The mobile station according to claim 7 wherein the operational state comprises a state where no application is currently running on the mobile station.

10. The mobile station according to claim 7 wherein the communication network is an 802.16e network.

11. The mobile station according to claim 7, wherein the processor is further programmed to cause the mobile station to stay in the first power saving mode based on predefined criteria.

12. The mobile station according to claim 11, wherein the predefined criteria include a type of subscription for the mobile station, a time of day or the second power saving mode being incompatible with an application of the mobile station.

13. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a mobile station that is capable of operating in at least two separate power saving modes—

a first power saving mode and a second power saving mode—

for causing the mobile station to support fast connection set-up in a communication network by;

entering an operational state associated with the second power saving mode; and

staying in the first power saving mode, thereby avoiding entry into the second power saving mode during the operational state, wherein in the first power saving mode, the mobile station remains registered with a communication network and in the second power saving mode, the mobile station is de-registered from the communication network.

14. The machine readable storage according to claim 13, wherein the first power saving mode is a sleep mode and the second power saving mode is an idle mode.

15. The machine readable storage according to claim 13, wherein the operational state comprises a state where no application is currently running on the mobile station.

16. The machine readable storage according to claim 13, wherein the communication network is an 802.16e network.

17. The machine readable storage according to claim 13, wherein the computer program causes the mobile station to stay in the first power saving mode based on predefined criteria.

18. The machine readable storage according to claim 17, wherein the predefined criteria include a type of subscription for the mobile station a time of day or the second power saving mode being incompatible with an application of the mobile station.
