Optimistic talk-permit reliability enhancement in a push-to-talk system

A method for increasing successful direct communications between a group of wireless telecommunication devices on a wireless communication network, comprising:

• a step for establishing a connection to a wireless network from a wireless telecommunication device being capable of selectively directly communicating across the wireless communication network with a target set of one or more other wireless telecommunication devices;
• a step for periodically informing a group communication server from the wireless telecommunication device of the presence of that wireless telecommunication device on the wireless telecommunication network, the group communication server selectively receiving requests to bridge direct communications between a communicating wireless telecommunication device and the one or more other wireless telecommunication device in a target set for that communicating wireless telecommunication device;
• a step for receiving a request at the group communication server from a wireless telecommunication device to bridge a direct communication to a target set of other wireless telecommunication devices on the wireless network;
• a step for determining the identity of the target set of one or more other wireless telecommunication devices at the group communication server;
• and
• a step for, if at least one of the wireless telecommunication devices of the target set has informed the group communication server of the presence of that wireless telecommunication device on the wireless network, bridging the requested direct communication between the communicating wireless telecommunication device and the target set of one or more other wireless telecommunication devices;
• further comprising
• a step for, if at least one of the wireless telecommunication devices of the target set has not informed the group communication server of the presence of that wireless telecommunication device on the wireless network, polling the wireless telecommunication devices to determine their presence on the wireless network prior to bridging the requested direct communication.
