20250106689
The present application relates to the field of communications, for example, a communication base station, a communication base station migration method, and a storage medium.
In the construction of wireless networks, the costs of hardware devices make up the largest expenditure, and the costs of base stations make up the majority of the costs of hardware devices. As a network size increases from a first-generation mobile communication technology (1G) network to a 5G network, an investment in base stations increases. In the 5G era, a diversity of new scenarios imposes new network requirements, and a base station increases in complexity, resulting in an increase in cost. In another aspect, the new wireless communication technology is gradually developing from a low frequency to a high frequency, and a high frequency band has the problems of a limited propagation distance and a reduced coverage range. Therefore, denser base stations need to be deployed in the future so that better signal coverage can be implemented, further increasing network construction costs. Therefore, how to reduce hardware costs in the construction of wireless networks has become an urgent problem to be solved.
The working and life styles in modern cities make people move very regularly. For example, during working time on working days, people gather in working places such as industrial parks and office buildings in urban areas. After working time and on holidays, people gather in residential areas, business areas, and entertainment places. Due to such movement of people in dense urban areas, the network construction in each area requires the planning of the number of base stations according to a maximum number of access users. Each base station is a device fixedly installed and can neither move along with users nor be deployed dynamically according to traffic changes in the urban area. With this design scheme, devices in each area cannot be fully utilized within one time period while needing to cope with the pressure of a traffic surge within another time period. For operators, a failure to make full use of the invested devices is a loss. Regular traffic surges cause a certain network congestion risk.

The communication base station includes a movable communication module and an unmovable connection module; the communication module includes a flight module, a first interface module, a power supply module, and a first alignment module; and the connection module includes a second alignment module, a second interface module, and a support module.

The first interface module is configured to docking with the second interface module in the connection module. The power supply module is configured to supply power to each module in the communication module. The first alignment module is employed for docking the communication module with the connection module. The second alignment module is configured to provide interface position information and alignment identifiers for the first alignment module in the communication module to enable the communication module to control the flight module to adjust a flight posture of the communication module and to enable the communication module to be connected to the connection module according to the interface position information and the alignment identifiers. The support module is configured to provide fixed support for the communication module connected to the connection module.
Embodiments of the present application provide a communication base station migration method. The communication base station migration method is applied to the communication base station according to any preceding embodiment and includes the following.
