Embodiment Construction

[0079] 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, and one CPS governs multiple E-Node Bs. That is to say, the control plane also adopts a two-layer architecture. In the control plane, taking into account the delay requirements and the characteristics of multi-cell management, the E-Node B implements the radio resource management function closely related to the E-Node B resources and characteristics under a single cell, and completes the establishment, maintenance and release of services; The CPS assists the E-Node B to complete radio resource management functions closely related to multiple cells and the entire network, for example, the management of the handover p...

Abstract

The system comprises: evolved core network; at least one control plane server (CPS), and multi E-NodeBs under each CPS. E-NodeB directly builds connection with evolved core network in order to implement the processing of radio interface physical layer, the management of its own radio resources, the multimedia broadcast / multicast, network sharing function and system broadcast, and the switch control between UE and different E-NodeBs. CPS is used for providing resources information of each cell and the cell radio resource management strategy for E-NodeB under its own control.

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...
