Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The technical solution of the embodiment of the present invention is applied to such as figure 1 In the communication scenario shown. Wherein, the broadband communication system and the narrowband trunking communication system are connected through a broadband and narrowband system fusion communication link, so that the broadband communication system and the narrowband trunking communication system can communicate with each other. The mobile terminal s...

Abstract

The invention provides a data transmission method applied to a mobile terminal. The method comprises the following steps: when narrowband service data information needs to be transmitted, detecting whether the mobile terminal is in a narrowband trunking communication system and a broadband communication system at the same time; if the mobile terminal is in the narrowband trunking communication system and the broadband communication system at the same time, selecting the narrowband trunking communication system or the broadband communication system to send the narrowband service data information; and if the mobile terminal is not in the narrowband trunking communication system and the broadband communication system at the same time, sending the narrowband service data information through the located communication system, wherein the broadband communication system can send the narrowband service data information to the narrowband trunking communication system or a destination terminal ofthe narrowband service data information. By adoption of the above technical scheme, the service capacity of the narrowband trunking communication system can be expanded, and the narrowband service delay is shortened.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a data transmission method, device, system and mobile terminal. Background technique [0002] The narrowband trunking communication system and the broadband communication system are communication systems that focus on carrying different types of services. Among them, the services carried by the narrowband trunking communication system are mainly voice services, supplemented by a small amount of data services; while the services carried by the broadband communication system are mainly data services, supplemented by a small amount of voice services. [0003] The real-time response performance of the narrowband trunking communication system is high, and the coverage area of ​​a single station is large. Using a single base station can provide narrowband business data transmission services for terminals in a wide range. However, due to the small bandwidth resourc...
