Delay timers for managing internal state changes and messages in user equipment for real-time multimedia applications
First Claim
1. In a cellular network, a method for regulating packet traffic between a client device having a contact list, a first timer, a second timer and a man-machine interface (MMI) layer, and a server configured to update the contact list, comprising the steps of:
- at the client device, generating a request to update the contact list;
determining if the first timer is running;
if the first timer is running, dropping the request; and
if the first timer is not running, starting the first timer and transmitting the request to the server.

Abstract
Timers in push-to-talk (PTT) enabled client devices are used to regulate packet traffic to and from the client device. In one embodiment, timers are used to maximize the user experience that occurs when the presence service is enabled in the PoC System. A first timer controls the flow of presence requests coming uplink from the UE to the presence server, and a second timer controls the flow of presence messages coming downlink from the presence server to the UE and associated presentation on the Man-Machine-Interface (MMI).

10. An improved push-to-talk enabled client device having a contact list and a man-machine interface (MMI) layer and configured to communicate over a push-to-talk network with a server to update the presence information in the contact list, the improvement comprising:
-
a first timer to control the transmission from the device to the server of a presence request to update the contact list; and
a second timer to control the receipt from the server to the device of a presence message with the presence update information. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
