Problems solved by technology
[0006] Due to the lack of control over the right to speak between terminals in the same group, the existing D2D communication cannot realize the orderly speech of users in the same group
Such a terminal cluster direct communication method will cause confusion at the command and dispatch site, and cannot meet the basic requirements of cluster applications

Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] In the embodiment of the present invention, the current master terminal sends a direct call establishment control indication, and the direct call establishment control indication includes a destination terminal ID, a source terminal ID, and a resource location of a competing speaking right. The slave terminal can apply for the speaking right to the current master terminal according to the direct call establishment control instruction, and the current master terminal determines the slave terminal to send the speaking right. The slave terminal obtains the right to speak at a specified time point. The direct call establishment control instructs the slave terminal to apply for the right to speak, so the orderly speaking of users in...

Provided is a D2D based direct communication method. The method comprises that a present master control terminal sends direct-connection call establishing control indication, and sends service data to a subordinate terminal in a delayed way; after receiving the direct-connection call establishing control indication, the subordinate terminal obtains the fact that a call service in the group is started from a target terminal ID, and receives the service data; the subordinate terminal proposes a discourse right application to the present master control terminal according to a source terminal ID and a resource position of the competition discourse right; the present master control terminal receives the discourse right application in the resource position of the competition discourse right, determines the subordinate terminal which sends the discourse right by judging the discourse right application, broadcasts discourse right conversion authorization, and releases the discourse right in a specific time point; and when receiving the authorization of the present master control terminal, the subordinate terminal obtains the discourse right in the specific time point, becomes a present master control terminal, and sends direct-connection call establishing control indication. Via embodiments of the invention, users in the same group can speak in an ordered way, and basic requirements for cluster application are met.
Description
technical field [0001] The present application relates to the technical field of communications, and more specifically, to a terminal-to-device-based trunking direct communication method. Background technique [0002] Device-to-device (D2D) communication is a technology that allows terminals to communicate directly by reusing cell resources under the control of the system. It can increase the spectral efficiency of the cellular communication system and reduce the terminal transmission power, which solves the problem to a certain extent. The problem of lack of spectrum resources in wireless communication systems. [0003] See attached figure 1 It is a schematic diagram of a 3GPP D2D channel structure. Logical channels include traffic channel (STCH) and broadcast control channel (SBCCH); transport channels include discovery channel (SL-DCH), shared channel (SL-SCH) and broadcast channel (SL-BCH); physical channels include physical discovery channel ( PSDCH), Physical Shared...
