Abstract

Abstract A method for routing data through a packet communications network (100) including the steps of generating a concatenated data packet containing a plurality of messages for transmission to a plurality of radios (134) in the network (100), appending a first set of assignment commands and destination codes to the concatenated data packet, and transmitting the concatenated data packet to a first set of radios (134A) of the plurality of radios (134) in a single transmission. The method further includes the steps of extracting messages from the concatenated data packet for the first set of radios (134A), appending a second set of assignment commands and destination codes to the concatenated data packet, and relaying the concatenated data packet to a second set of radios (134B) of the plurality of radios (134) in a single transmission. In a preferred embodiment, the adaptive protocol for packet communications network (100) of the present invention forms the concatenated data packet in a headend radio (118). The data packet includes the set of codes for the first set of radios (134A) directly communicating with the headend radio (118) . The data packet is transmitted to the first set of radios (134A) in a single transmission during each frame. Messages having a destination code for a radio of the first set of radios (134A) are extracted and sent to a host device serving the first set of radios (134A). The data packet is reformatted to include the second set of codes and is retransmitted to the second set of radios (134B) in a single transmission.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 180 words
In a packet communications network (100) having a headend radio (118) for receiving and temporarily storing a concatenated message block from a central computer (102) for transmission to a plurality of remote radios (134), the improvement characterized by: a first control microprocessor (138) located within said headend radio (118) for generating a concatenated data packet containing a plurality of messages for transmission to said remote radios (134) and for appending a first set of codes to said data packet; an antenna (144) in communication with said first control microprocessor (138) for transmitting said data packet to a first set of radios (134A) of said remote radios (134) in a single transmission; and a second control microprocessor (138A) located within one of said first set of radios (134A) of said remote radios (134) for extracting messages from said data packet for said first set of radios (134A) and for appending a second set of codes to said data packet and for relaying said data packet to a second set of radios (134B) of said remote radios (134) in a single transaction.
Claim 2
Dependent Claim 26 words
The packet communications network (100) of Claim 1 further including a link control microprocessor (140) for applying forward error correction coding to said concatenated data packet.
Claim 3
Dependent Claim 21 words
The packet communications network (100) of Claim 1 further including a transceiver (142) for modulating and demodulating said concatenated data packet.
Claim 4
Dependent Claim 30 words
The packet communications network (100) of Claim 1 further including a serial communication controller (136) located within said headend radio (118) for receiving and temporarily storing said concatenated message block.
Claim 5
Dependent Claim 17 words
The packet communications network (100) of Claim 1 wherein said antenna (144) is an omnidirectional RF antenna.
