Network shared systems, network connection method and access method for user equipment

Abstract

The invention provides network shared systems, a network connection method and an access method for user equipment and belongs to the technical field of communication. A network shared system comprises at least two eNodeB-CUs (Central unit) and an eNodeB-DU (Distributed unit). Each eNodeB-CU belongs to different operators. At least two CU-DU interfaces are set on the eNodeB-DU. Each CU-DU interface corresponds to an operator. Each eNodeB-CU establishes network connection with the eNodeB-DU through utilization of the CU-DU interfaces of the belonging operators. According to the network shared systems, the network connection method and the access method, each operator owns the independent eNodeB-CU, can independently decide functions supported by the eNodeB-CUs, can carry out upgrading management on the eNodeB-CU without negotiating with the other operators and can independently determine partial wireless parameters of the eNodeB-CUs, so autonomous control capacity and competitiveness ofthe operators for a network in a network shared scene is improved, and security of operation and maintenance data is improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a network sharing system, a network connection method, and a user equipment access method. Background technique [0002] With the intensified competition of communication services and the increase of total cost of ownership (Total Cost of Ownership, TCO), more and more operators begin to seek network sharing. Wherein, network sharing refers to the sharing of network facilities between two or more operators. Through the sharing of network facilities, it is possible to reduce network construction costs and reduce network operating expenses. Considering the competition among different operators, at present different operators mainly share access network hardware resources (ie, base stations). [0003] With the evolution of wireless base stations, the evolved base station (E-UTRAN NodeB, eNodeB) can be split into eNodeB-central unit (Central unit, CU) network ...

AI Technical Summary

Problems solved by technology

If the eNodeB-CU is shared among multiple operators in the traditional way, there will be problems among multiple operators in negotiating the functional features that the eNodeB-CU needs to support, the wireless network configuration of the eNodeB-CU, and negotiating the upgrade management of the software in the eNodeB-CU. It is not conducive to each operator's ability to independently control the network; in addition, in terms of network operation and maintenance, eNodeB-CU needs to be operated and maintained through a public EMS, which reduces the security of operation and maintenance data
