The invention can be used in a wireless communication system to meet the diversified data service requests of users through the mutual cooperation of the low-frequency control base station and the high-frequency data base station.
Background
In recent years, with the rapid development of mobile communication technology, the variety of terminal devices and applications tends to diversify, the user demands naturally also show diversity and time variation, and the mobile data traffic is increased dramatically, which all promote the development of the next generation communication system. But the current state of the wireless communication spectrum is: the low-frequency band spectrum resources are mostly occupied and are increasingly tense, and the high-frequency band spectrum resources are not developed and utilized, so that the method has a larger utilization space. The future mobile communication network will develop towards high frequency band, forming the situation of coexistence of high frequency and low frequency. Therefore, high-low frequency convergence networking is a trend of development of a future 5G mobile communication system.
A patent document applied by China network Xinjiang electric power company Changji discloses a method and a system for hybrid networking of electric wireless private networks (application date: 2017, 10 and 17 months, application number: 201710962417.X, publication number: CN 107708129A). The method comprises the steps that the working frequency band of a macro base station is set to be a 1.8GHz frequency band, and the working frequency band of a micro base station is set to be a 230MHz frequency band; and setting client terminal equipment, realizing communication connection between the macro base station and the micro base station according to the client terminal equipment, and executing conversion between a 230MHz frequency band and a 1.8GHz frequency band through the client terminal equipment. The disadvantages of the system are: when a macro base station in the system provides a high-rate data service, the coverage area is small, and when a micro base station in the system completes large-range coverage, only a low-rate data service can be provided for a user, so that the problem of low spectrum efficiency is caused. The method has the following defects: in the method, the data plane and the user plane of the macro base station and the micro base station are tightly coupled, which is not beneficial to centralized management control and flexible expansion of new services.
The patent document "an inter-frequency networking method" (application date: 2013, 6 and 28 months, application number: 201310268802.6, publication number: CN104254080A) applied by the company china mobile communication group discloses an inter-frequency networking method. The method sets the frequency point of each cell of a base station arbitrarily selected from a designated area, so that the frequency point of at least one cell of the selected base station is different from the frequency points of other cells of the selected base station; and setting the frequency points of the cells of the close adjacent base stations without the frequency points of the base stations with the set frequency points, so that each cell of each base station has the same number of the same-frequency close adjacent cells and the same number of different-frequency close adjacent cells. The method has the following defects: the method cannot effectively reduce the disturbed degree of each cell in the pilot frequency networking, and influences the service quality of the user, so that the service experience of the user is poor.
