A method in a first portable communication device (1102) of a plurality of portable communication devices located in a first cell (1104) of a plurality of cells for establishing communication with a second portable communication device (1106) located in a second cell, comprises determining whether a message originated by the first portable communication device exceeds a predetermined length. If the message exceeds the predetermined length, the method further comprises determining whether the second device is reachable before sending the message to the second device. If the second device is determined to be reachable, the message is transmitted using an appropriate propagation path by acquiring a third portable communication device (1124) located within a first central region (1112) of the first cell, instructing the third portable communication device to acquire a first set of six portable communication devices (1126, 1128, 1130, 1138, 1140, 1142), each located in a different sector (1132, 1134, 1136, 1144, 1146, 1148) of an outer region of the first cell from each other, instructing the first set of devices to transmit the message to a second set of six portable communication device (1126, 1128, 1130, 1138, 1140, 1142), each of the second set of devices located in a central region of a different cell adjacent to the first cell, and indicating the message is leaving the first cell. It is then determined if the second portable communication device (1106) has received the message.
