Method and system for identifying neighboring evolved NodeB, and method and system for configuring evolved NodeB ID

Abstract

The invention discloses a method and a system for identifying a neighboring evolved NodeB (eNB), and a method and a system for configuring an evolved NodeB ID (eNB ID), which relate to the field of communication. The method for identifying the eNB ID of a neighboring eNB includes the following steps: a source eNB receives the ECGI of a neighboring cell sent by a terminal side; the source eNB determines whether it is configured to open a flexible eNB ID identification mode; if it is configured to open a flexible eNB ID identification mode, the source eNB extracts a first eNB ID composed of a basic eNB ID and an extended eNB ID from the ECGI; the source eNB sends a target eNB ID identification request carrying the basic eNB ID and the extended eNB ID to a core network; and the core network feeds back an address identification result to the source eNB. Through the methods and the systems of the invention, a scheme for increasing the addressing capacity of eNB ID is realized, unnecessary waste of idle cell ID addressing is reduced, intercommunication in a hybrid networking scenario with eNB IDs of different length is realized, there is no effect on terminals, and good backward compatibility and good deployment feasibility are achieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and system for identifying base station identifiers of adjacent base stations, and a method and system for configuring base station identifiers. Background technique [0002] ECGI (E-UTRAN Cell Global Identifier, E-UTRAN cell global identifier) ​​is globally unique and consists of three parts: PLMN ID, eNodeB ID, and Cell ID. Such as figure 1 Therefore, ECGI can be used to identify a cell (or carrier sector), create base station and cell data, send the broadcast information to the terminal for network selection, assist SON (Self-Organized Networks, self-organizing network) functions and positioning services, and billing It works in scenarios such as distinguishing the place where the business occurs in the bill. PLMN ID (Public Land Mobile Network, public land mobile network) is the mobile network number, eNodeB (Evolved Node B, evolved Node B) ID ...

Problems solved by technology

like figure 2 As shown, since the air interface of the terminal is not allowed to be affected, the information currently reported by the terminal cannot distinguish the length of the base station ID used by the neighboring cell; if PCI partitions are used to distinguish base station IDs of different lengths or manual configuration, manual configuration workload will be caused increase and increase the difficulty of PCI planni...
