1. A wireless communication system comprising:
- a plurality of mobile communication units, each mobile communication unit being operative to convert speech patterns to a voice message and wirelessly transmit the voice message to one or more other mobile communication units, the plurality of mobile communication units being configured as a self-contained mobile network infrastructure, at least one of the plurality of mobile communication units comprising an integrated router that comprises a router database defining connections to members of the self-contained mobile network infrastructure, such that the router receives the voice message from at least one of the plurality of mobile communication units, extracts routing information comprising a member list of intended recipients of the voice message from the voice message, removes the intended recipients of the voice message that are connected to the router from the member list, and transmits the voice message to the intended recipients of the voice message that are connected to the router, and routes the voice message to at least one additional router if there are remaining intended recipients in the member list.

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.

10. 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; a 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 comprising a member list of intended recipient destination two-way radio devices of the digitized voice packets 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 the destination two-way radio devices for the digitized voice packets, the routing algorithm reconfiguring the optimal routing path and removing members within communication range of the router from the member list, transmitting the digitized voice packets to the destination two-way radio devices that are within the communication range of the router and routing the digitized voice packets to at least one additional router if there are remaining intended recipients of the digitized voice packets in the member list. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. 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; 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, the routing information including a member list of intended recipients of the digitized voice packets, the means for determining also providing to the digitized voice packets new routing information and removing members from the member list based on members connected to the means for routing; and means for retransmitting the digitized voice packets to the members connected to the means for routing and for routing the digitized voice packets to at least one additional means for routing if there are remaining intended recipients of the digitized voice packets on the member list.

20. 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 routing information comprising a member list of intended recipients of 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 and connections to mobile communication units within the range of the first mobile communication unit; the first mobile communication unit modifying the routing information in the voice message based on the determined optimal path and removing recipients of the voice message in the member list that are within the range of the first mobile communication unit; 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 within the range of the first mobile communication unit according to the determined optimal path, and to at least one additional mobile communication unit if there are remaining intended recipients of the voice message in the member list. - View Dependent Claims (21, 22, 23)
