Method and device for managing user equipment

Abstract

The embodiment of the invention discloses a method and a device for managing user equipment. A long-term evolution distributed antenna system (LTE DAS) cell comprising a plurality antenna units (AU) is divided into a plurality of subareas; the subareas correspond to one or more Aus; and in the cell, the subarea is adopted as a unit so as to schedule resources for the UE and carry out interference control and mobile management. By application of the invention, the efficiency in interference management and switching can be improved, and the system capacity is increased.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and device for managing user equipment (UE, UserEquipment). Background technique [0002] The Distributed Antenna System (DAS, Distributed Antenna System) was first proposed in the 2G system to solve coverage problems in indoor scenarios. The wireless access structure of the DAS includes one or more antenna units (AU, Antenna Unit) and a central processing unit (CU, CentralUnit), where one AU is deployed on each floor or room, and each AU is installed with one or more The root antenna is placed at a certain distance in the cell. The AU serves the UEs in its coverage area. Multiple AUs are connected to the CU through cables. The CU can be a component unit in the cell base station (Node B). Usually, each The AUs send exactly the same signal, that is, the single frequency network (SFN, Single Frequency Network) signal transmission method is adopted. The area cover...

Problems solved by technology

In the LTE system, the eNodeB has the RRM capability and does not need to report measurement information to the core network. Therefore, in the LTE system, it is obvious that the UE management method in UMTS cannot be applied.

[0011] It can be seen from the above that the existing UMTS system performs interference and mobility management in units of cells. When performing interference management, the cell-level interference management method is used, that is, all AUs in the DAS cell will reduce or increase power at the same time, but this This interference management method will affect other adjacent cells, which will cause difficulties in inter-cell interference management and low interference management efficiency; while performing mobility management, resources are reserved for all AUs in the cell for new access In this way, resources are wasted and the system capacity is low; furthermore, for the LTE system, there is currently no specific implementation plan for managing UEs
