Abstract
A method and apparatus is provided for communicating a group message packet among wireless communication devices (WCDs) over a wide area communication network that includes a first infrastructure device (ID), a second ID and a third ID. A first communication connection is established between an envoy packet duplicator module (EPDM) that is in communication range of a source wireless communication device (WCD) and a first envoy module implemented at the first ID that is in communication range of a first destination WCD. The EPDM is implemented at the third ID. The source WCD communicates a group message packet from the source WCD to a third envoy module implemented at the third ID, which forwards the group message packet to the EPDM. The EPDM generates a first copy of the group message packet destined for the first destination WCD, and communicates the first copy of the group message packet to the first envoy module.
