Direct mode communication system and communication attaching method thereof

摘要

A direct-mode communication system comprises a first client direct-mode communication apparatus and a backhaul network. The first client direct-mode communication apparatus transmits a register signal to the backhaul network to register with the backhaul network. After the first client direct-mode communication apparatus is registered, the backhaul network determines a location relationship between the first client direct-mode communication apparatus and a second client direct-mode communication apparatus. The backhaul network transmits a piece of wi-fi connection information to the first client direct-mode communication apparatus according to the location relationship. The first client direct-mode communication apparatus creates a wi-fi direct-mode communication connection with the second client direct-mode communication apparatus according to the piece of wi-fi connection information.

主权项

1. A communication attaching method for use in a direct-mode communication system, the direct-mode communication system comprising a first client direct-mode communication apparatus and a backhaul network, the first client direct-mode communication apparatus connecting with the backhaul network, and the backhaul network further connecting with a second client direct-mode communication apparatus, the communication attaching method comprising:
(a) enabling the first client direct-mode communication apparatus to transmit a register signal to the backhaul network to register with the backhaul network; (b) enabling the backhaul network to determine a location relationship between the first client direct-mode communication apparatus and the second client direct-mode communication apparatus after the step (a); (c1) enabling the backhaul network to transmit a wi-fi creating request message to the second client direct-mode communication apparatus according to the location relationship so that the second client direct-mode communication apparatus determine a first client network address, a second client network address and a wi-fi channel according to the wi-fi creating request message; (c2) enabling the backhaul network to receive the first client network address, the second client network address and the wi-fi channel from the second client direct-mode communication apparatus after the step (c1); (c3) enabling the backhaul network to transmit the piece of wi-fi connection information to the first client direct-mode communication apparatus, wherein the piece of wi-fi connection information comprises the first client network address, the second client network address and the wi-fi channel; and (d) enabling the first client direct-mode communication apparatus to create a wi-fi direct-mode communication connection with the second client direct-mode communication apparatus in the wi-fi channel according to the first client network address and second client network address.
