Embodiment Construction

[0077] The core of the present invention lies in adopting a two-layer architecture mode in which the evolved core network Evolved CN and the evolved base station E-Node B are directly connected on the user plane, and the E-Node B directly establishes a connection with the Evolved CN through an IP network. At the same time, the control plane server CPS is introduced into the system of the present invention. One Evolved CN governs one or more CPSs, and one CPS governs multiple E-Node Bs. That is to say, the control plane adopts a three-layer architecture. In the control plane, both the delay requirement and the characteristics of multi-cell management are considered, and the radio resource management function is distributed in the E-Node B and the CPS: the E-Node B implements a single cell that is closely related to the resources and characteristics of the E-Node B The radio resource management function completes functions such as service establishment, maintenance and release; t...

Abstract

The invention discloses a radio communication system, which comprises: evolved core network; at least one control plane server (CPS) dominated by the evolved core network, and multi E-NodeBs dominated by each CPS. E-NodeB builds connection with evolved core network in order to implement the processing of radio interface physical layer and the management of its own radio resources. CPS is used for implementing the management of multi cells. The invention also discloses a management method and a cell switching method based on radio resources of the radio communication system. By use of the invention, it can greatly reduce the time delay of user plane, improve the processing speed and efficiency of radio resources management, and guarantee the higher switching success rate.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a wireless communication system and its wireless resource management method and cell switching method. Background technique [0002] With the development of the third generation mobile communication technology, network planning and optimization work is becoming more and more important. Due to the rapid increase in the number of mobile users and the continuous emergence of new services, the system is required to obtain good network capacity and meet certain wireless coverage requirements under the condition of supporting multiple services and meeting certain QoS (Quality of Service) conditions. At the same time, by adjusting capacity, A balanced relationship between coverage and quality provides the best service. [0003] The purpose of network optimization is to improve the quality of service to users and improve the utilization of network resources. Theref...
