Terminal operating within an ad-hoc, peer-to-peer radio network
First Claim
1. A terminal for operation within an ad hoc, peer to peer radio system, wherein the terminal is a hop of a routing path connecting a call from a source to a destination, the terminal comprising:
- a communicating means for transmitting and receiving signals based on time-division messaging, said signals being transmitted during a series of time frames (TF) each divided into a series of time slots (TS) comprising at least one time slot in which control signals are transmitted; and
other time slots in which are transmitted data signals, wherein said at least one time slot transmitting control signals at a first frequency of F0, and said other time slots (TS) transmitting data signals at frequencies of F1, F2, and F3, respectively, each of said time frames (TF) comprising an inter-frame time gap (IFTG) at the end of each of said time frames (TF) in which no signals are transmitted, wherein said inter-frame time gap (IFTG) has a length different than said time slots, whereby said terminal is allowed time to perform necessary calculations, wherein each of said time frames (TF) further comprises a last time slot (LTS);
a processor; and
a memory for storing computer executable code to be executed by the processor, for generating initial said control signals in a respective last time slot (LTS) of a respective time frame (TF) indicating initial presence of a respective terminal in order to start communicating with other terminals, wherein said at least one time slot (TS) for said control signals is transmitted at a first power level, and said other time slots (TS) for said data signals are transmitted at a second power level, wherein said second power level is equal to or less than said first power level that is computed according to quality reports received from all terminals in a service group.

Abstract
A terminal for operation within an ad-hoc, peer-to-peer radio system wherein the system includes a series of radio terminals forming a service group. The terminal having a transceiver for communicating with terminals in the same service group, computer means, and memory for storing program software. Within the system, the terminal establishes a connection with one radio terminal based on time-division access; initiating an outgoing call from the radio terminal including registering with another radio terminal for serving as a node in the call connection by transmitting a registration request; and initially transmitting said registration request on a last time slot (TS) of a respective time frame (TF), said last time slot serving as a configuration channel.

12. A terminal for operation within an ad hoc, peer to peer radio system, wherein the terminal is a hop of a routing path connecting a call from a source to a destination, the terminal comprising:
-
a communication means for making at least one of an outgoing call or receiving an incoming call; a processor; and
a memory for storing computer executable code to be executed by the processor, coupled to the communication means for generating communications information for transmission based on time-division messaging, said communications-information being transmitted during a series of time frames (TF) each divided into a series of time slots (TS);
said time frames comprising at least one time slot in which control-channel (CC) messaging information is transmitted, and other time slots in which is transmitted channel data (CD) messaging information, said at least one time slot transmitting said control-channel information at a first frequency of F0, and said other time slots (TS) transmitting said channel data (CD) information at frequencies of F1, F2, and F3, respectively, each of said time frames (TF) comprising an inter-frame time gap (IFTG) at the end of each of said time frames (TF) in which no communications-information is transmitted, whereby said terminal is allowed time to perform necessary calculations, wherein the length of each of said time slots for transmitting said communications-information is equal to each other, each of said time frames (TF) further comprises a last time slot (LTS); andsaid computer executable code further comprising code for generating initial control communications-information in a respective last time slot (LTS) of a respective time frame (TF) indicating initial presence of a respective terminal in order to start communicating with other terminals, and wherein said computer executable code further comprises code for switching transmission of initial control communications information from said last time slot (LTS) to another, free, earlier time slot of a subsequent time frame (TF) in order to reduce the chance of collision with other terminals also initially registering. - View Dependent Claims (13, 14)
