Data transmission method, transfer equipment and terminal

Abstract

An embodiment of the invention discloses a data transmission method, terminals and transfer equipment. The data transmission method comprises the steps that a first calling terminal receives duration offset transmitted by the first transfer equipment through using a first time slot, and the duration offset is determined by the first transfer equipment according to first service data, the first calling terminal determines a first target moment according to the duration offset when receiving an instruction of initiating second service communication and transmits second service data to the first transfer equipment according to preset time slot length from the first target moment, and the time slot resource used by the first calling terminal when initiating the second service data is not overlapped with the time slot resource used by a second calling terminal when initiating the first service data. According to the data transmission method, the transfer equipment and the terminals, the calling terminals do not need to undergo the synchronization process, namely, the calling terminals do not need to wait for the time of completing time slot synchronization of the calling terminals and the transfer equipment when initiating service communication, and the service data transmission of the calling terminals can be accelerated.

Description

technical field [0001] The invention relates to the field of private network communication, in particular to a data sending method, a transfer device and a terminal. Background technique [0002] Private communication network or private network, as a supplement to public communication network or public network, refers to the construction within some industries, departments or units to meet their organizational management, safety production, dispatching and commanding needs dedicated communication network. Generally, it only provides non-commercial telecommunication services internally, and does not undertake the obligation of universal service to the society. It should be understood that dedicated communication networks have been widely used in fields such as electric power, petroleum, metallurgy, and transportation. With the development of society and the advancement of technology, the status and role of private networks are constantly changing. Among them, the police di...

Problems solved by technology

That is, when the mobile terminal (caller) initiates business communication, it needs to wait for a period of time to complete the time slot synchronization between the mobile terminal (caller) and the transfer device, resulting in a delay in sending service data from the mobile terminal (caller)
