Abstract

A method and apparatus to manage the paging cycle of a communication device are disclosed. The method includes receiving, by an element of a communication system, at least one message comprising an idle mode request, a battery charge level of a battery of the communication device, and a desired paging information from the communication device, from the communication device, determining a paging information for the communication device based on the battery charge level by selecting a first paging cycle when the battery charge level meets a charge level criteria and selecting a second paging cycle when the battery charge levels does not meet the charge level criteria, the second paging cycle being longer than the first paging cycle, and transmitting a response message comprising the determined paging information to the communication device.

Claims

1. A method of managing the paging cycle of a communication device comprising:

receiving, from a communication device at an element of a communication system, at least one message comprising an idle mode request, a battery charge level of a battery of the communication device, and a desired paging information from the communication device;

determining, at the element of the communication system, a paging information for the communication device based on the battery charge level; and

transmitting, by the element of the communication system, a response message comprising the determined paging information to the communication device.

2. The method of claim 1, wherein determining the paging information for the communication device comprises selecting a first paging cycle when the battery charge level meets a charge level criteria and selecting a second paging cycle when the battery charge levels does not meet the charge level criteria, and the second paging cycle is longer than the first paging cycle.

3. The method of claim 2, wherein the charge level criteria comprises a predetermined percentage of the maximum capacity of the battery of the communication device and the predetermined percentage is selected by a network operator of the communication system.

4. The method of claim 2 wherein the charge level criteria comprises 50% of the maximum capacity of the battery of the communication device.

5. The method of claim 1, wherein

the communication system comprises a wireless communication system,

the at least one message comprises a deregistration request,

the response message comprises a deregistration command, and

the element of the communication system comprises a processing unit configured to perform a network control and management system abstraction layer to determine the paging information for the communication device.

6. A method of managing the paging cycle of a communication device comprising:

receiving, from a communication device at an element of a communication system, at least one message comprising an idle mode request and a desired paging information from the communication device;

retrieving, by the element of the communication system, a battery charge level of the communication device recorded at a previous time from a database of the communication system;

determining, by the element of the communication system, a paging information for the communication device based on the battery charge level of the communication device; and

transmitting, by the element of the communication system, a response message comprising the determined paging information to the communication device.

7. The method of claim 6, wherein determining a paging information for the communication device comprises selecting a first paging cycle when the battery charge level meets a charge level criteria and selecting a second paging cycle when the battery charge levels does not meet the charge level criteria, and the second paging cycle is longer than the first paging cycle.

8. The method of claim 7, wherein the charge level criteria comprises a predetermined percentage of the maximum capacity of the battery of the communication device and the predetermined percentage is selected by a network operator of the communication system.

9. The method of claim 6, wherein determining the paging information for the communication device comprises:

determining an updated battery charge level of the of the communication device based on the battery charge level of the communication device recorded at the previous time and a difference between the previous time and the current time;

selecting a first paging cycle when the battery charge level meets a charge level criteria; and

selecting a second paging cycle when the battery charge levels does not meet the charge level criteria, wherein the second paging cycle is longer than the first paging cycle.

10. The method of claim 9, wherein the charge level criteria comprises a predetermined percentage of the maximum capacity of the battery of the communication device and the predetermined percentage is selected by a network operator of the communication system.

11. The method of claim 6, wherein

the communication system comprises a wireless communication system,

the at least one message comprises a deregistration request,

the response message comprises a deregistration command, and

the element of the communication system comprises a processing unit configured to perform a network control and management system abstraction layer to determine the paging information for the communication device.

12. An element of a communication system comprising:

a communication interface configured to communicate with a communication device; and

a processing unit, coupled to the communication interface, configured to;

receive from the communication device at least one message comprising an idle mode request and a desired paging information from the communication device;

determine a paging information for the communication device based on a battery charge level of the communication device; and

transmitting through the communication interface a response message comprising the determined paging information to the communication device.

13. The element of claim 12, wherein determining the paging information for the communication device comprises selecting a first paging cycle when the battery charge level meets a charge level criteria and selecting a second paging cycle when the battery charge levels does not meet the charge level criteria, and the second paging cycle is longer than the first paging cycle.

14. The element of claim 13, wherein the at least one message further comprises the battery charge level of the communication device.

15. The element of claim 14, wherein the charge level criteria comprises a predetermined percentage of the maximum capacity of the battery of the communication.

16. The element of claim 15, wherein

the communication system comprises a wireless communication system,

the at least one message comprises a deregistration request,

the response message comprises a deregistration command, and

the processing unit is further configured to perform a network control and management system abstraction layer to determine the paging information for the communication device.

17. The element of claim 13, wherein determining the paging information for the communication device comprises:

retrieving, by the element of the communication system, a recorded battery charge level of the communication device recorded at a previous time from a database of the communication system; and

determining the battery charge level of the of the communication device based on the recorded battery charge level and a difference between the previous time and the current time.

18. The element of claim 17, wherein the charge level criteria comprises a predetermined percentage of the maximum capacity of the battery of the communication.

19. The element of claim 18, wherein

the communication system comprises a wireless communication system,

the at least one message comprises a deregistration request,

the response message comprises a deregistration command, and

the processing unit is further configured to perform a network control and management system abstraction layer to determine the paging information for the communication device.
