Abstract
Systems and methods are provided for routing voice communications through a mobile communication system having a self-contained infrastructure, such as a two-way radio communication system. The voice communications are transmitted as digitized voice packets over radio frequency links. The digitized voice packets contain one or more destination addresses in addition to other routing information. Routers receive the digitized voice packet and extract the routing information. The routing information is used in conjunction with a member router database to determine where to route the digitized voice packets.

12. A two-way radio communication system comprising:
-
a plurality of two-way radio devices operative to convert speech patterns to digitized voice packets and wirelessly transmit digitized voice packets over at least one radio frequency link, the plurality of two-way radio devices being configured as a self-contained mobile network infrastructure, at least one of the plurality of two-way radio devices having an integrated router having a processor and a memory, the memory stores a router database defining members within communication range of the router, the router having a routing algorithm that extracts routing information from the digitized voice packets and utilizes the extracted routing information and router database to determine an optimal routing path from a plurality of routing paths to destination two-way radio devices for the digitized voice packets. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A half duplex two-way radio communication system having a self-contained infrastructure defining a mobile network, the system comprising:
-
a plurality of half-duplex two-way radio devices operative to convert speech patterns to voice messages and having integrated means for routing digitized voice packets between the plurality of two-way radio devices;
means for configuring the integrated means for routing to provide the means for routing with a router database defining connections between members in the network;
means for updating the router database based on changes in the network; and
means for determining an optimal routing path from a plurality of routing paths based on the router database and routing information in the digitized voice packets.

22. A method for communicating voice messages within a two-way radio communication system, the method comprising:
-
a first mobile communication unit receiving a voice message from a second mobile communication unit of the two-way radio communication system;
the first mobile communication unit extracting routing information from the voice message;
the first mobile communication unit determining an optimal routing path based on routing information and a router database defining member connections within the two-way radio communication system;
the first mobile communication unit modifying the routing information in the voice message based on the determined optimal path; and
the first mobile communication unit retransmitting the voice message including the modified routing information to at least one other mobile communication unit in the two-way radio communication system according to the determined optimal path. - View Dependent Claims (23, 24, 25)
