Abstract

A method and apparatus for transitioning states or modes on a user equipment, the method having the steps of receiving, at a network element, a transition indication; checking a radio resource profile for the user equipment; and making a transitioning decision at the network element based on the received transition indication and the radio resource profile.

Claims

1. A method comprising:

receiving, at a network element from a user equipment, an indication message;

checking a radio resource profile for the user equipment, wherein the radio resource profile reflects a composite of application transition profiles and each application transition profile reflects transition information for an application on the user equipment; and

making a transition decision at the network element based on the received indication message and the radio resource profile.

2. The method of claim 1 wherein the indication message is triggered by a message from an application on the user equipment indicating that the application is finished with an exchange of data.

3. The method of claim 1 wherein the indication message further includes data embedded therein.

4. The method of claim 3 wherein the data includes one or more of a cause indication, a probability of error, and a radio resource profile aspect.

5. The method of claim 1 wherein the radio resource profile includes static profile information.

6. The method of claim 5 wherein the static profile information includes an access point name, quality of service, or a packet data protocol context.

7. The method of claim 1 wherein each application transition profile includes information reflecting whether the state of the user equipment should enter transition at all, state transition preferences, delay or inactivity timer values, or a probability that a user equipment is correct to request a transition.

8. The method of claim 1 wherein the radio resource profile comprises quality of service for a radio bearer or radio access bearer, access point name, packet data protocol context, historical information for the user equipment.

9. The method of claim 1 wherein the transition decision is a decision selected from the group:

do nothing;

transition to a less battery intensive state;

transition to an idle mode; and

tear down one or more radio access bearers.

10. The method of claim 1 wherein the transition decision is a decision to transition to a more battery efficient state.

11. A network element comprising:

a communications subsystem adapted to receive an indication message;

memory; and

a processor adapted to check a radio resource profile for a user equipment, the processor further adapted to make a transitioning decision based on the received indication message and the radio resource profile, wherein the radio resource profile reflects a composite of application transition profiles and each application transition profile reflects transition information for an application on the user equipment.

12. The network element of claim 11 wherein the indication message is a message from an application on the user equipment indicating that the application is finished with an exchange of data.

13. The network element of claim 11 wherein the indication message further includes data embedded therein.

14. The network element of claim 13 wherein the data includes one or more of a cause indication, a probability of error, and a radio resource profile aspect.

15. The network element of claim 11 wherein the radio resource profile includes static profile information.

16. The network element of claim 15 wherein the static profile information includes an access point name, quality of service, or a packet data protocol context.

17. The network element of claim 11 wherein the transition profile includes information reflecting whether the state of the user equipment should enter transition at all, state transition preferences, delay or inactivity timer values, or a probability that a user equipment is correct to request a transition.

18. The network element of claim 11 wherein the radio resource profile comprises quality of service for a radio bearer or radio access bearer, access point name, packet data protocol context, historical information for the user equipment.

19. The network element of claim 11 wherein the transition decision is a decision selected from the group:

do nothing;

transition to a less battery intensive state;

transition to an idle mode; and

tear down one or more radio access bearers.

20. The network element of claim 11 wherein the memory is adapted to store the radio resource profile.

21. The network element of claim 11 wherein the transition decision is a decision to transition to a more battery efficient state.
