Patent ID: 7266104

Claim:
A method of transmitting radio calls in an ad-hoc, peer-to-peer radio system comprising a series of radio terminals forming a service group, each of said radio terminals comprising transceiver means for transmitting and receiving signals from other terminals of said series of terminals in the same service group, computer means and memory means for storing program software means therein, comprising: (a) establishing a connection with one of said radio terminals based on time-division access; (b) said step (a) comprising transmitting and receiving control and data signals as a series of time frames (TF) with each said time frame consisting of a plurality of time slots (TS); (c) said step (b) comprising dedicating one of said plurality of time slots for use as a configuration channel for transmitting information useful in establishing a routing path of a call; (d) said step (b) further comprising dedicating other of said plurality of time slots for use as data channels for transmitting the actual call information based on the class of service (COS) of the call; (e) said step (b) further comprising forming an inter-frame time gap (IFTG) between said time frames (TF) during which each radio terminal may process said data received from another one of the terminals; (f) initiating an outgoing call from said one of said radio terminals; (g) said step (f) comprising registering with another one of said radio terminals for serving as a node in the call connection by transmitting a registration request; and (h) said step (g) comprising initially transmitting said registration request on a last time slot (TS) of a respective time frame (TF), said last time slot serving as said configuration channel.
