Abstract

The invention provides a wide-narrow band communication device which mainly comprises a broadband controller, a narrow-band controller and a main controller, wherein the main controller determines a target working mode according to the obtained working mode selection instruction, and controls the controller corresponding to the target working mode and the peripheral circuit to work. When the target working mode is a narrow-band mode, the narrow-band controller is controlled to work and a shared peripheral circuit is controlled to accept the control of the narrow-band controller. When the target working mode is in a broadband mode, the broadband controller is controlled to work and the shared peripheral circuit is controlled to accept the control of the broadband controller. When the targetworking mode is a wide-narrow band mode, the broadband controller and the narrow-band controller are controlled to be a master-slave mode, and the shared peripheral circuit is controlled to accept the control of the controller of the master mode. Therefore, the wide-narrow band communication device supports both narrowband service and broadband service, so that the requirement of private networkcustomers on the large data service is met.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a broadband and narrowband communication device and method. Background technique [0002] Private network refers to a private network, a network within a certain system, which only serves the system, for example, a special network for railway systems, a special network for public security systems, a special network for flood control, and a special network for military use. The public network is an ordinary circuit switching network, for example, a network set up by various operators to serve the public. [0003] With the development of the private network industry, while private network users require reliable voice services, they also gradually have more demands for big data services such as video surveillance and multimedia broadcasting. In the market broadband demand increases and public network 4G (the 4G th Driven by the rapid development of Generation mobile ...
