All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

With the development of a communication network, terminal services of the emergency communication network are expanded from single trunked voice to high-definition audio and video, multimedia graphics and texts, live video conference, sensing of the Internet of things, indoor and outdoor positioning and the like. Therefore, how to provide an emergency communication network with high speed, high stability and high safety for an emergency rescue scene has become a primary task for developing a current emergency communication system. In the prior art, the 5G wireless communication technology has the advantages of high speed, large capacity and low delay and is gradually applied to an emergency communication system. The inventor finds that the 5G backhaul capacity is multiplied due to the fact that the 5G technology supports a large-bandwidth working frequency band and a large-scale antenna technology, but in the prior art, in a common emergency communication system such as a communication system based on the 5G CPE technology, the 5G CPE depends on the coverage quality and the channel capacity of a host base station, and only can provide a small-capacity, single-link and unstable backhaul capacity. Thus, there still exists a problem of stability and low bi-directional transmission rate of the emergency communication network.

In order to solve the above technical problems, the embodiments of the present application provide the following technical ideas for solving the problems: firstly, through using a modularized integrated 5G small base station component integrating a small base station and an aggregation backhaul device and utilizing a communication public network base station and a core network resource, after the 5G small base station component is rapidly opened, a transmission link between the public network base station and the core network is assembled behind a firewall through an aggregation gateway, the influence on the transmission and processing of information and application flow between private network user equipment and an emergency service platform is reduced, and therefore the stability and the bidirectional transmission rate of an emergency communication network of an emergency communication system are improved.
