Problems solved by technology

[0006] However, in the prior art, since the macro cell and the micro cell are independent networks, the macro base station and the micro base station interact with the network side independently through network-side functional entities, which may bring some negative impacts to the system
For example, due to the sm...

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0034] First of all, it needs to be explained that in the prior art, the reason why the system will be negatively affected is that the macro cell and the micro cell are independent networks, and the functions that the micro base station and the macro base station need to complete are basically the same. Therefore, In terms of functions, micro base stations and macro base stations are equivalent to each other. However, under this equal relationship, it may have a negative impact on the system....

Abstract

The invention discloses a cellular communication system, a method for the inter-cell handover of a terminal and a macro base station. The cellular communication system comprises the macro base station and at least one micro base station within the coverage of the macro base station. The macro base station is used for establishing a control channel for the terminal of the micro base station, performing accessing management operations on the micro base stations within the coverage, receiving a handover request of the terminal and realizing the handover of the terminal to another micro base station within the coverage. The micro base station is used for establishing a data channel for an accessing terminal to perform data transmission with the terminal. By the system, the method and the macro base station, a user control plane and a data plane under a micro cell can be separated, so that the resources of the micro base station can be better used for data communication. Therefore, negative impact on the system can be reduced in a macro cell-micro cell coexisting networking way.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a cellular communication system, a method for switching a terminal between cells and a macro base station. Background technique [0002] In the second-generation communication system, the needs of users are mainly voice calls and short messages, and the requirements for spectrum efficiency are not high. The system is mainly limited by the size of the coverage area. Therefore, macro-cell networking is generally used, and the distance between base stations is generally large. , the cost of this networking method is low. [0003] However, with the development of the third and fourth generation communication systems, data transmission has become a new requirement, especially for real-time video transmission, the requirements for spectrum efficiency and network throughput have increased significantly, but due to the large coverage of macro cells, it is difficult to accom...
