Methods, systems and apparatus are disclosed for using effective radiated transmit power of a base station at a wireless communication device to determine whether the wireless communication device is within uplink transmission range of the base station. The wireless communication device can also use the effective radiated transmit power to adjust transmit power at the wireless communication device and save battery resources. In one implementation, the disclosed embodiments can be applied in a two-way wireless communication system.

Methods for using effective radiated transmit power of a base station at a wireless communication device to determine uplink transmission range and/or to adjust transmit power

A method () of implementing floor control in a communications system (). The method can include receiving a random symbol from each of a plurality of communication devices () or network nodes (). From the plurality of random symbols, a random symbol that satisfies a criteria can be identified. Floor ownership can be granted to a selected one of the communication devices associated with the identified random symbol or from which the identified random symbol was received.

Methods, systems and apparatus are disclosed for using effective radiated transmit power of a base station at a wireless communication device to perform an automatic roaming method. In one implementation, the disclosed embodiments can be applied in a two-way wireless communication system.

Wireless communication device using a base station radiated effective transmit power for performing an automatic roaming

A method and apparatus for linking to a Peer-to-Peer ('P2P') network for VOIP communications. An intermediary peer creates a map to link peers together in the P2P network. A series of messages are generated to open the ports of one peer to be accessible to other peers on the P2P network. Peers are then enabled to communicate directly with other peers. Steward peers can assume the functionality of the intermediary peer.
