System and method for simultaneously accessing LTE (Long Term Evolution) public network and LTE private network

Abstract

The invention relates to a system for simultaneously accessing an LTE (Long Term Evolution) public network and an LTE private network. The system comprises a first network module, a second network module, a main control board, an SIM (Subscriber Identity Module) card, a memory, a WiFi (Wireless Fidelity) module and a power supply module, wherein the first network module and the second network module are in communication connections with the main control board; the power supply module is electrically connected with the main control board; the memory and the WiFi module are in communication connections with the first network module and the second network module; the SIM card is in a communication connection with the main control board; an LTE public network communication module or an LTE private network communication module can be switched and selected in real time by a selection module according to a communication demand in order to perform a wireless network communication; the LTE public network and the LTE private network are recognized by a recognition module, and an execution module is used for executing a network needing to be accessed; and service demands at a multi-network fusion transition stage is met well, and remarkable economic benefit and social benefit can be achieved. Moreover, the system has the advantages of low implementation cost, stable and reliable performance, and easiness and convenience in applications.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication system for realizing interconnection between a private network and a public network. Background technique [0002] The LTE public network refers to the public network currently built by operators such as China Mobile, China Unicom, and China Telecom. LTE private network trunking communication refers to a wireless communication network that provides professional applications in specific groups such as government departments and enterprises. Currently, most of the LTE terminals on the market only support public network access or LTE private network access. If you need to access the public network and the private network at the same time, you need to have two independent devices to complete this requirement. The disadvantages are that the system is more complicated, the cost is increased, and the efficiency is reduced. Due to the use of two independent...
