A high-low frequency cooperative networking system and method

Abstract

A high-low frequency cooperative networking system and method comprises a low-frequency control soft base station, a central controller, a high-frequency control soft base station and a user. The method comprises the following steps: (1) accessing a user; (2) sending a data service request; (3) forwarding the data service request; (4) determining a target high frequency data soft base station; (5)judging whether a network slice satisfying the needs of the user exists, if so, executing the step (7), otherwise, executing the step (6); (6) constructing network slices to meet the needs of users;(7) scheduling network slices to meet user needs; (8) service of user receiving data. The system of the invention greatly improves the overall spectrum efficiency of the system while improving the coverage range of the network area. The method of the invention has flexible expansibility to realize centralized management and control of the whole network, and at the same time enables users to obtainbetter service experience.

Description

technical field [0001] The present invention belongs to the technical field of communication, and further relates to a system and method for high and low frequency cooperative networking in the technical field of wireless communication. The invention can be used in the 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 technique [0002] In recent years, with the rapid development of mobile communication technology, the types of terminal equipment and applications tend to be diversified, and user demands are naturally diverse and time-varying, and mobile data traffic has surged. These demands have promoted the development of next-generation communication systems develop. However, the status quo of the current wireless communication spectrum is that most of the low-band spectrum resources are occupied and are becoming...

AI Technical Summary

Problems solved by technology

The disadvantages of this system are: when the macro base station in the system provides high-speed data services, the coverage area is small; low problem

The disadvantage of this method is that the data plane and user plane of the macro base station and micro base station are tightly coupled in this method, which is not conducive to centralized management and control and flexible expansion of new services

The disadvantage of this method: this method cannot effectively reduce the degree of interference of each cell in the inter-frequency network, which affects the user service quality and makes the user's service experience poor
