Embodiment Construction

[0053] According to the embodiment of the present invention, the RN device determines and sends cell information according to the number of cells that need to be assigned cell identities. Identify and send allocation information, where each cell identity uniquely identifies a cell, and the RN device determines the cell identity corresponding to each cell according to the received allocation information from the base station. Since the base station allocates cell identities for RN equipment, conflicts between cell identities allocated by RN OAMs of different manufacturers are avoided, manual participation is saved, maintenance costs are reduced, and allocation efficiency is improved.

[0054] Wherein, the cell identifier in the embodiment of the present invention may be ECGI (E-UTRAN Cell Global Identifier, Evolved Universal Terrestrial Radio Access Network cell global identifier) ​​or PCI (Physical Cell Identity, physical layer cell identifier), and other unique identifiers Di...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method, a system and equipment for allocating cell identifiers, and is used for solving the problem of increase of the maintenance cost of the system caused by cell identifier collision which possibly occurs during allocation of the cell identifiers to relay-node (RN) equipment in the prior art. The method provided by the embodiment of the invention comprises the following steps that: a base station determines the quantity of the cell identifiers which are required to be allocated to the RN equipment according to cell information which is received from the RN equipment,; the base station allocates the cell identifiers to the RN equipment according to the determined quantity, wherein each cell identifier uniquely identifies a cell; and the base station determines allocation information according to the allocated cell identifiers and sends the allocation information to the RN equipment. By allocating the cell identifiers to the RN equipment by using the base station, the collision of the cell identifiers which are allocated by the RN operation and maintenance (OAM) equipment of different manufacturers is avoided, allocation efficiency is improved, manual operation is avoided, and maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for allocating and determining cell identifiers. Background technique [0002] After the LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade) system introduces the Relay (relay) node, the following nodes, interfaces and links are defined, such as figure 1 as shown, [0003] Nodes include: [0004] Donor-eNB: An eNB that is wirelessly connected to the RN device, abbreviated as DeNB; [0005] Relay-Node: an entity existing between DeNB and UE, abbreviated as RN device; [0006] Relay-UE: UE that directly interacts with RN equipment for data, abbreviated as R-UE; [0007] Macro UE: a UE that directly exchanges data with the DeNB. [0008] Interfaces include: [0009] Un interface: the interface between the RN device and the DeNB; [0010] Uu interface: interface between UE and RN equipment. [0011] Wireless ...
