Patent Images
1. A method to facilitate presence-related updates, comprising:
- detecting when a communication unit becomes active notwithstanding whether the communication unit self-initiates a network presence update;
automatically sourcing a network presence update message on behalf of the communication unit from an entity other than the communication unit.

Abstract
Upon detecting when a communication unit (12) becomes active in a network, and further upon determining that this communication unit became active without also simultaneously self-initiating a network presence update, another network entity (14) automatically sources a network presence update message on behalf of the communication unit. Such a message may be directed, for example, to a presence server (15). In a preferred approach, such presence updates are batched and provided to a subscribing mobile communication unit pursuant to a corresponding resource conservation strategy.

10. The method of 1 and further comprising:
when the communication unit does self-initiate a network presence update, automatically updating the communication unit with respect to at least some network presence information.

15. A system to facilitate maintaining at least relatively current presence information at a mobile communication unit, comprising:
-
a wireless communication interface having a two-way wireless link with the mobile communication unit at least from time to time;
a presence detector that is operably coupled to the wireless communication interface and having a mobile communication unit presence-detected output that provides a presence-detected output signal regardless of whether the mobile communication unit has requested an update of presence information;
a presence server;
a presence information update requester that is operably coupled to the mobile communication unit presence-detected output of the presence detector and having a mobile communication unit presence information request output operably coupled to the presence server. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method comprising:
-
at a Packet Data Serving Node (PDSN);
receiving an indication that a communication unit has become active, which indication does not indicate that the communication unit has also requested an update of presence information;
automatically sourcing a message to request that an update of presence information as corresponds to the communication unit be transmitted to the communication unit. - View Dependent Claims (26, 27, 28)
