System for realizing direct communication and interconnection of two small-scale wireless private networks, and communication method thereof

Abstract

The invention provides a system for realizing direct communication and interconnection of two small-scale wireless private networks, and a communication method thereof. The system comprises the two small-scale wireless private networks; each small-scale wireless private network is equipped with a base station, a plurality of terminals and radio station equipment; a wireless public network module is embedded in the radio station equipment. The communication method of the system comprises the following steps: a wireless public network communication link circuit is established between the two small-scale wireless private networks; when the wireless public network communication link circuit is in a hold mode, direct communication between the radio station equipment / terminals at the two ends is realized through the wireless public network. According to the invention, the advantages of the wireless public network is used to perform point supplement on a coverage blind zone, without geographical or distance limitations, so that low cost is realized, the networking application is simple, convenient and flexible, and is very suitable for meeting actual requirements of transregional temporary emergency networking during implementing emergency tasks; the investment of private network users can be protected and value-added, remarkable economic benefit and social benefit can be generated, and various application service requirements in a multi-network integration transition stage can be met.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a system and a communication method for realizing direct interconnection of two small wireless private networks. Background technique [0002] In the construction of a professional wireless communication network, a single-base station large-area coverage scheme or a distributed base station simulcast system is generally used for large-scale coverage. It is more expensive to achieve coverage in corner areas or areas with complex terrain, and in the event of an emergency, only an independent small network can be formed to operate in isolation, and it cannot be connected to the remote command and dispatch system. [0003] In the face of on-site command and dispatch of emergencies, users often need to temporarily form a network in the coverage blind area of ​​the remote private network base station, or temporarily establish a direct call between several frequency groups of diffe...
