Problems solved by technology

[0009] The existing technology has not provided a solution for the cell management under the local access node when the UE aggregates the cell resources of multiple base stations / nodes at the same time; due to the limitation of the RRC function of the local access node, it is also necessary to consider the Macro eNB assists local access nodes to realize autonomous cell management and control of local access nodes, improving base station management efficiency

specific Embodiment 1

[0060] in such as figure 2 In the existing layered network shown, the macro base station (referred to as Macro eNB) provides basic coverage, and the low-power small base station (referred to as Local eNB in ​​this paper) provides hotspot coverage. There is a data / signal network between Local eNB and Macro eNB. The command interface (which can be a wired or wireless interface), and the UE can work under the Macro eNB or Local eNB. Since the coverage area of ​​the cell controlled by the Local eNB is small and there are few UEs served, the UE connected to the Local eNB can often obtain better service quality, such as obtaining a higher service rate and a higher quality link. Therefore, when the UE connected to the Macro eNB enters the coverage of the cell corresponding to the Local eNB, it can transfer to the Local eNB to obtain the services provided by the LocaleNB; when the UE is far away from the coverage of the cell corresponding to the Local eNB, it needs to transfer to the...

specific Embodiment 2

[0081] The UE reports the measurement results of each frequency point under the local access node to the MacroeNB through the Macro cell; the Macro eNB exchanges information such as the UE identity and the reported measurement results with the local access node aggregated with it; the local access node interacts with the Macro eNB self-management of the serving cell under the base station; the local access node determines that it is necessary to perform cell management of the UE under the base station (such as adding / modifying / deleting the secondary cell, and , the configuration / change of the primary cell), the local access node exchanges information such as UE identity, cell identity, and radio resource configuration to the Macro eNB, and the Macro eNB notifies the UE to perform corresponding operations through RRC signaling. Wherein, the local access node does not have the RRC function and is only responsible for part of user data transmission; or is only responsible for RRC ...

Abstract

The invention discloses a cell management method and device under a local access node, which are used for realizing cell management under a local access node when user equipment UE aggregates cell resources of multiple base stations. The method includes: in the scenario where the user equipment UE aggregates cell resources of multiple base stations, the local access node receives the UE's measurement information of the cell under the local access node through an evolved macro base station Macro eNB; Determine whether to perform cell management under the local access node on the UE based on the measurement information of the cell under the local access node; when the local access node determines that it is necessary to perform cell management under the local access node on the UE , the local access node notifies the UE of the cell management information.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell management method and device under a local access node. Background technique [0002] The network architecture of Evolved Universal Terrestrial Radio Access (E-UTRAN) is as follows: figure 1 As shown, E-UTRAN is composed of evolved base stations (evolvedNode B, eNB). The eNB completes the function of the access network, and communicates with the user equipment (User Equipment, UE) through the air interface. Both a control plane connection and a user plane connection exist between the UE and the eNB. For each UE attached to the network, a Mobility Management Entity (MME) provides services for it, and the MME is connected to the eNB through a control plane S1 interface (S1 for the control plane, S1-MME). The S1-MME interface provides UE with control plane services, including mobility management and bearer management functions. The S-GW is connected to the ...
