Providing presence information in a communication network
First Claim
1. A method of providing presence information, the method comprising:
- designating, for a plurality of communication devices, a plurality of groups, and assigning each of the communication devices to at least one of the groups;
preparing a communication having presence information corresponding to a status of the plurality of communication devices in the at least one group;
determining at least one network infrastructure device serving the at least one group; and
transmitting, in accordance with the communication interface, at a pre-determined time, the communication to a plurality of network infrastructure devices including the at least one network infrastructure device.

Abstract
A server (101) designates and assigns each of a plurality of communication devices to at least one of a plurality of groups. The server (101) prepares a communication having presence information corresponding to a status of the communication devices in the group; determines network infrastructure device(s) serving the group; and transmits, at a pre-determined time, the communication to the network infrastructure device(s). A network infrastructure device (103a-c, 105a-f) receives the communication and transmits, as a common channel signal during the pre-determined time, a signal with the presence information. A communication unit (107a, 107b, 107c) receives an indication of the pre-determined time; transmits, at an interval proximate to the pre-determined time, a signal indicating the communication device'"'"'s status; and receives, at the pre-determined time, the signal with the presence information.

15. A communication unit, comprising:
-
a transceiver for receiving signals when operably connected to a communication network; and
a processor, the processor being configured to facilitate first receiving, from a connection initiated by the communication network, an indication of a pre-determined time for exchanging presence information;
transmitting, at an interval proximate to the pre-determined time and in accordance with the transceiver, at least one signal having presence information indicative of a status of the communication unit; and
second receiving, in accordance with the transceiver, a transmission initiated by the communication network at the pre-determined time, having presence information corresponding to at least one other communication unit. - View Dependent Claims (16, 17, 18, 19, 20)
