Method and apparatus for idle mode synchronization
First Claim
1. A method to manage idle mode operation of a communication device in a communication system comprising:
- receiving, by a node of the communication system from the communication device, a request to enter idle mode comprising a request to enable automatic renewal of an internet protocol (IP) address currently assigned to the communication device comprising a length of an IP address lease timer corresponding to the IP address currently allocated to the communication device and a length of an IP address update lease timer corresponding to the IP address;
transmitting, to an IP address allocation unit which allocated the IP address to the communication device, the idle mode request;
receiving, from the IP address allocation unit, an idle mode response comprising an IP lease update acknowledgement associated with the idle mode request;
transmitting, to the communication device, the idle mode response;
enabling, by the node of the communication system, automatic renewal of the IP address;
configuring, by the node of the communication system, an idle mode timer corresponding to the IP address update lease timer, wherein the communication device enters idle mode after receiving the idle mode response and before the idle mode timer expires; and
transmitting, by the node of the communication system to the IP address allocation unit, an IP lease update request corresponding to the IP address, when the idle mode timer expires and the communication device is in idle mode.

Abstract
A method and system to manage idle mode operation of a communication device are disclosed. The method includes receiving from the communication device a request to enter idle mode comprising a request to enable automatic renewal of an internet protocol (IP) address currently assigned to the communication device, transmitting, to an IP address allocation unit which allocated the IP address to the communication device, the idle mode request, receiving, from the IP address allocation unit, an idle mode response comprising an IP lease update acknowledgement associated with the idle mode request, transmitting, to the communication device, the idle mode response, enabling automatic renewal of the IP address, configuring an idle mode timer, and transmitting to the IP address allocation unit, an IP lease update request corresponding to the IP address, when the idle mode timer expires and the communication device is in idle mode.

8. A communication system element comprising:
-
a communication interface configured to communicate with at least an internet protocol (IP) address allocation unit and an access node of the communication system; and a processing system coupled to the communication interface comprising a processing unit and a storage unit, the processing system configured to control the communication system element to; receive, from the access node, a request to enter idle mode comprising a request to enable automatic renewal of an IP address currently assigned to a communication device comprising a length of an IP address lease timer corresponding to the IP address currently allocated to the communication device by the IP address allocation unit and a length of an IP address update lease timer corresponding to the IP address by the IP address allocation unit; transmit, to the IP address allocation unit, the idle mode request; receive, from the IP address allocation unit, an idle mode response comprising an IP lease update acknowledgement associated with the idle mode request; transmit, to the access node, the idle mode response; enable automatic renewal of the IP address; configure an idle mode timer corresponding to the IP address update lease timer, wherein the communication device enters idle mode after receiving the idle mode response and before the idle mode timer expires; and transmit, to the IP address allocation unit, an IP lease update request corresponding to the IP address, when the idle mode timer expires and the communication device is in idle mode. - View Dependent Claims (9, 10, 11, 12, 13, 14)
