First Claim
1. A system for providing advanced voice services in one or more wireless communications networks, comprising:
- one or more servers that interface to the wireless communications networks to perform advanced voice services for one or more mobile units in the wireless communications networks, wherein the advanced voice services include an instant two-way half-duplex voice call within a group of the mobile units comprising a Push-to-Talk-over-Cellular (PoC) call session;
wherein both the servers and the mobile units that use the advanced group services communicate with each other using control messages within the wireless communications networks, and at least one of the servers switches voice messages for the advanced group services between the mobile units across the wireless communications networks;
wherein at least one of the servers manages the PoC call session by acting as an arbitrator for the PoC call session and controls the sending of the control messages and the voice messages to and from the mobile units; and
wherein at least one of the servers exchanges messages with the mobile units, in order to indicate that a user is neither online or offline, but is temporarily unreachable or unavailable.

Abstract
A system and method for providing advanced voice services in a wireless communications network. The system includes at least one server that exchanges messages with mobile units, in order to indicate that a user is neither online or offline, but is temporarily unreachable or unavailable. The user may be temporarily unreachable or unavailable due to connectivity issues with the user'"'"'s mobile unit in the wireless communications network. Presence information for the user is distributed from the server to watchers, wherein the presence information indicates that the user is offline when the user is temporarily unreachable or unavailable. Various techniques may be implemented to determine how long the user'"'"'s mobile unit must remain connected to the wireless communications network, before the presence information indicates that the user is online.
