Method, terminal and system for dual-mode communication between public network and private network

Abstract

The invention provides a method, a terminal and a system for dual-mode communication between a public network and a private network. The method comprises the steps of: carrying out network search by a dual-mode single-standby terminal; when either a first network or a second network is searched only, residing in the searched network; when the first network and the second network are searched, residing in the searched first network or second network according to a preset selection mode; and when the dual-mode single-standby terminal resides in the first network, initiating a first network service to the first network, wherein the first network is the public network and the second network is the private network; or the second network is the public network and the first network is the private network. According to the invention, the dual-mode communication between the public network and the private network is realized, a user can realize a public network service and a private network service through one dual-mode terminal, so that two types of terminals are unnecessary to carry separately, and the user is facilitated in usage.

Description

technical field [0001] The invention relates to a dual-mode communication method, terminal and system for a public network and a private network, and belongs to the technical field of wireless communication. Background technique [0002] The public network refers to the public wireless communication network operated by the telecom operator, such as the GSM service or China Mobile service launched by China Mobile; the private network refers to a professional wireless communication network, such as the trunking communication network of the public security system. [0003] However, dual-mode communication between the public network and the private network cannot be realized in the prior art, that is, only public network terminals can be used in the public network, and only private network terminals can be used in the private network. If the user needs to use the two types of networks, the two types of terminals need to be carried separately, which is very inconvenient. Conten...

[0003] However, the dual-mode communication between the public network and the private network cannot be realized in the prior art, that is to say, only public network terminals can be used in the public network, and only private network terminals can be used in the private network

If users need to use these two types of networks, they need to carry these two types of terminals separately, which is very inconvenient
