Abstract
The invention relates to the communication field, and particularly relates to an LTE (long term evolution) system, and more particularly to a selecting method, a device and a system for rebuilding cells in the LTE system. The method comprises the following steps: a network side determines a neighboring cell of the serving cell where UE (user equipment) is positioned, and whether the neighboring cell and the serving cell belong to the cell under the same eNode B; and the network side transmits the corresponding identification information representing that whether the neighboring cell and the serving cell belong to the cell under the same eNode B to the UE. According to the method provided by the invention, the identification of the relation between the neighboring cell and the serving cell is added in the system message content for identifying whether the neighboring cell and the serving cell belong to the same eNode B, so that the problem that the rebuilding success rate is low in the cell rebuilding process is solved.
Description
Technical field
The present invention relates to communication field, relate in particular to LTE (Long Term Evolution, Long Term Evolution) system, particularly re-establish system of selection and the equipment and system of residential quarter in a kind of LTE system.
Background technology
Along with 3-G (Generation Three mobile communication system) (Third-generation mobile system, sustainable development 3G), Long Term Evolution (Long Term Evolution, LTE) project is at third generation partner program (The 3rd Generation Partnership Project, be suggested 3GPP), owing to can obtain higher user data rate, improve power system capacity and the advantages such as coverage rate, rationally flexibly frequency spectrum resource distribution, so that LTE obtains fast development, many operator's plans are arranged at present or disposing the LTE system.
In the LTE network, because the scenes such as RLF (Radio Link Failure, Radio Link Failure) are in safe activation and the UE under the RRC connected state (User Equipment, terminal) can initiate to re-establish process.The condition that base station side is accepted the request that re-establishes is that safe activation of the contextual information of this UE and its AS (Access Stratum, Access Layer) must be contained in the base station.So UE is in re-establishing process, only have and select to belong to an eNodeB (Evolved NodeB with former persistent district (rebuilding front resident residential quarter) or with switching target small area, evolved NodeB) residential quarter under just can rebuild successfully, and existing agreement can't guarantee that the residential quarter selected is satisfied and re-establishes requirement, thereby can't guarantee the success rate that re-establishes.
