Method for scheduling switched terminal, method for switching terminal and base station

Abstract

The invention discloses a method for scheduling a switched terminal, a method for switching a terminal and a base station, belonging to the field of communication technology. The method for scheduling the switched terminal comprises a step that a target base station schedules a terminal from a source base station on a protected subframe. The method for switching the terminal comprises the following steps: the target base station carries out switching optimization according to indication information; the indication information is used for indicating the terminal from the source base station as a disturbed terminal; or the indication information is used for indicating that switching decision carried out on the terminal from the source base station is based on an ABS measurement result; or the indication information is used for indicating that a measurement mode of the terminal from the source base station is ABS measurement; or the indication information is used for indicating the target base station to schedule the terminal from the source base station on the protected subframe; or the indication information is used for indicating scheduling of the terminal from the source base station on a specific subframe.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for scheduling a handover terminal, a handover method and a base station. Background technique [0002] In a network with inter-cell interference, take an LTE (Long Term Evolution, Long Term Evolution) heterogeneous network as an example, such as Figure 1a As shown, small base stations, such as micro base stations (Pico), home base stations (HeNB), home base stations (Femto), relay stations (Relay) and other wireless access points are placed within the coverage of a macro base station (Macro eNB). Then, the UE (User Equipment, user terminal) within the coverage of the small base station is under the dual coverage of the Macro eNB and the small base station. In such a heterogeneous network, a UE is connected to a cell, which is called a serving cell of the UE, and a base station generally has one or more cells. [0003] And for cells in the network, there...

Problems solved by technology

For open access cells, in order to allow the small base station to absorb more terminals in the hotspot area, it is possible to add offsets to the measurement results to allow more terminals at the edge of the small base station to access the small base station. The signal of the macro cell is stronger than the signal strength of the small base station, so it brings interference to the terminal

For closed subscriber group cells, some terminals served by open access cells (including macro cells or micro cells), because they do not have the access authority of the closed cell, when the terminal approaches the closed cell, although the signal of the closed cell is stronger than the current The serving cell, but cannot be handed over because it cannot be accessed, resulting in strong interference to the terminal
