DIRECT MODE COMMUNICATION SYSTEM AND COMMUNICATION ATTACHING METHOD THEREOF

United States

Overview

A direct-mode communication system includes a first client direct-mode communication apparatus and a first backhaul network. The first client direct-mode communication apparatus transmits a proximity notification request to a second backhaul network via the first backhaul network so that the second backhaul network returns a proximity notification acknowledgement (ACK) signal. The first backhaul network receives a piece of first client location information and a piece of second client location information from the first direct-mode communication apparatus and the second backhaul network respectively, and determines a location relationship accordingly. The first backhaul network transmits a Wi-Fi connection signal to the first client direct-mode communication apparatus according to the location relationship. The first client direct-mode communication apparatus establishes a direct-mode communication connection with a second client direct-mode communication apparatus according to the Wi-Fi connection signal.
