Abstract
A wireless communication system (100) having portable communication devices (102, 104, and 106) capable of establishing direct terminal (102)-to-terminal (104) communication (108 and 110) and indirect terminal (102)-to-terminal (104) communication (112, 118 and 114, 116) through another terminal (106) without having a fixed base station. A portable communication device (106) used as a terminal is capable functioning as a router for communication (112, 118 and 114, 116) between other portable devices (102 and 104) in the system. While functioning as a router, the portable device (106) is capable establishing and maintaining a separate direct communication (302 and 304) with another portable communication device (306). A wireless communication system(600) utilizing predetermined cell- and location-specific communication parameters (808) and non-repeating propagation patterns (1200) for portables communication devices in the system for establishing communications.

12. A method for a first portable communication device of a plurality of portable communication devices located at a first location in a first cell of a plurality of cells to establish communication with a second portable communication device of the plurality of portable communication devices located at a second location in a second cell wherein each of the plurality of portable communication devices having a positioning system receiver receiving location information from a positioning system and having a transceiver for communication at a particular frequency band, wherein each of the plurality of cells is assigned to a predetermined geographical area, has a boundary defining the geographical area, has a central region round a center, a second region surrounding the center region and an outer region surrounding the second region within the boundary, and is divided into six sectors wherein each sector is adjacent to a different cell, the method comprising steps of:
-
acquiring a third portable communication device of the plurality of portable communication devices located within a first central region of the first cell;
instructing the third portable communication device to acquire a first set of up to three portable communication devices of the plurality of portable communication devices wherein each of the first set of up to three portable communication devices is located in a different sector of the first cell from each other;
acquiring a second set of up to three portable communication devices of the plurality of portable communication devices located in a first outer region of the first cell wherein each of the second set of up to three portable communication devices is located in a different sector of the first cell from each other and from the first set of up to tree portable communication devices;
transmitting a first message targeted for the second portable communication device along with an out-of-cell broadcast request to the third portable communication device and to the second set of up to three portable communication devices located in the first outer region;
instructing the third portable communication device to re-transmit the first message targeted for the second portable communication device along with the out-of-cell broadcast request to the first set of up to three portable communication devices located in the first outer region;
instructing the first and second sets of up to three portable communication devices upon reception of the out-of-cell broadcast request to re-transmit the first message to cells adjacent to each of the first and second sets of up to three portable communication devices; and
determining if the second portable communication device has received the first message. - View Dependent Claims (13, 14, 15, 16)

17. A method in a first portable communication device of a plurality of portable communication devices located at a first location in a first cell of a plurality of cells for establishing communication with a second portable communication device of the plurality of portable communication devices located at a second location in a second cell, the method comprising steps of:
-
determining whether a message originated by the first portable communication device exceeds a predetermined length;
if the message exceed the predetermined length, determining whether the second portable communication device is reachable before sending the message to the second portable communication device;
if the second portable communication device is determined to be reachable, transmitting the message using an appropriate propagation path by;
acquiring a third portable communication device of the plurality of portable communication devices located within a first central region of the first cell;
instructing the third portable communication device to acquire a first set of six portable communication devices of the plurality of portable communication devices wherein each of the six portable communication devices is located in a different sector of the outer region of the first cell from each other; and
