[0020] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0021] The existing integrated base station solutions still have the following shortcomings and are difficult to meet the application needs of vertical industries: (1) The existing integrated base station only supports base station functions and core network functions. The horizontal connection means require external connection of various different communication devices. In terms of use, it is still not a truly integrated design.

[0022] (2) The horizontal self-organizing network system supported by the existing integrated base station is designed on a case-by-case basis and cannot flexibly support various horizontal connection methods.

[0025] In order to solve the above technical problems, the following embodiments of the integrated base station of the present application and the 5G fusion method based on the integrated base station are proposed.

[0026] Reference Figure 1 ,like Figure 1 The figure shows a structural block diagram of an integrated base station according to an embodiment of the present application. The base station includes six parts, namely, a base station unit, a core network unit, a heterogeneous horizontal connection unit, a network control unit, a security protection unit, and an application service unit.

[0027] Among them, the base station unit serves as the main control unit and provides high-speed access to 5G terminals; the core network unit provides core network functions of the 5G network, including AMF, UDM, AUSF, SMF, PCF, UPF and other network elements; the heterogeneous cross-connection unit provides distributed cross-connection functions between base stations on demand, loads the corresponding cross-connection waveform software and configuration in a software-defined manner according to the requirements of the usage scenario, and flexibly provides medium- and short-distance self-organizing network cross-connection means, or long-distance satellite cross-connection means, etc.; the network control unit provides networking control functions for various heterogeneous cross-connection means; the security protection unit provides security protection functions such as air interface signaling detection and network access authentication enhancement; the application service unit provides local computing resources for the nearby deployment of various application services.

For example: When the cross-connection distance belongs to medium-short distance cross-connection, combined with the geographical environment and cross-connection bandwidth requirements, the waveform and configuration corresponding to the medium-short distance self-organizing network cross-connection that meets the requirements are loaded.

The local security protection unit of the integrated base station performs security detection on the terminal access signaling and completes the communication network access authentication process; S5. The local core network unit of the integrated base station provides access management and session management for the terminal and completes the network attachment process; S6. The local network control unit of the integrated base station obtains access information of the user terminal from the local core network unit to form location management information of each terminal; S7. The network control units of different integrated base stations synchronize the location management information of each terminal with each other to form a full network location topology of the user terminal.

[0032] Among them, the manner in which the integrated base station establishes horizontal communication with other integrated base stations includes: According to the surrounding geographical environment, cross-connection distance, cross-connection bandwidth requirements, etc., the corresponding cross-connection waveform and configuration are loaded in a software-defined manner, and a cross-connection communication link that meets the application requirements is established on demand.

[0033] Step 0: Horizontal networking: Horizontal networking is performed between the integrated base stations.

[0038] Step 5: Distributed synchronization of user terminal access locations: Integrated base station A notifies and synchronizes the user terminal access location information to other integrated base stations.

[0039] Step 6: Provide uplink and downlink services. The integrated base station A provides uplink and downlink services to the user terminal.
