Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0043] With the development of communication networks, the terminal services of emergency communication networks have also expanded from single cluster voice to high-definition audio and video, multimedia text and image, video conference live broadcast, Internet of Things sensing, indoor and outdoor positioning, etc. Therefore, how to provide an emergency communication network with high speed, high stability and high safety for the rescue site has become the primary task of the current emergency communication system research and development. In the prior art, 5G wireless communication technology has the advantages of high speed, large capacity and low delay, and is gradually applied to emergency communication systems. The inventors have found that, due to the support of large bandwidth working frequency bands and large-scale antenna technology by 5G technology, the 5G backhaul capacity has increased exponentially, but in the commonly used emergency communication systems such as the communication system based on 5G CPE technology, the 5G CPE relies on the coverage quality and channel capacity of the host base station, and can only provide small capacity, single link and unstable backhaul capacity. Therefore, there is still a problem of low stability and bidirectional transmission rate of the emergency communication network.

[0044] To solve the above technical problems, the embodiments of the present application provide the following technical concept for solving the problem: first, by using a modular integrated 5G small base station assembly of an integrated small base station and an aggregation backhaul device, and utilizing the communication public network base station and core network resources, after quickly opening the 5G small base station assembly, the transmission link between the public network base station and the core network is collected behind the firewall through the aggregation gateway, thereby reducing the influence of the message and application flow between the private network user equipment and the emergency service platform during transmission and processing, and improving the stability and bidirectional transmission rate of the emergency communication network of the emergency communication system.
