Network sharing system, network connection method and user equipment access method

Abstract

The disclosure provides a network sharing system, a network connection method, and a user equipment access method, which belong to the field of communication technologies. The network sharing system includes: at least two eNodeB-CUs and one eNodeB-DU, each eNodeB-CU belongs to a different operator, the eNodeB-DU is provided with at least two CU-DU interfaces, each CU-DU The DU interface corresponds to an operator, and each eNodeB-CU establishes a network connection with the eNodeB-DU through the CU-DU interface of the operator it belongs to. Since each operator in this disclosure has an independent eNodeB-CU, they can independently determine the functions supported by the eNodeB-CU, and can upgrade and manage the eNodeB-CU without negotiating with other operators, and can independently determine the eNodeB-CU Therefore, it improves the operator's ability to independently control the network and competitiveness in the network sharing scenario, and improves the security of operation and maintenance data.

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
