Abstract
A location independent personal telecommunications system is presented that utilizes an out-of-band bi-directional burst data communications network to assist in the routing of personal communications via an in-band voice and data communications network. Access to the out-of-band network for communication is regulated by a multiple access communications protocol. Each user is synchronized with the other users of the network to the protocol and will access the network only during certain time periods that are reserved by the protocol for message traffic between network users. A collision avoidance scheme is included in the protocol to resolve instances of simultaneous transmission of message traffic by multiple users during the same time period.
