Embodiment Construction

[0060] In order to save system resources when sending the time slot switch point change information to the relay device, in this embodiment, the relay device monitoring center transmits the second switch point change information to the relay device. Meanwhile, in order to make the relay device and the base station switch the uplink and downlink time slots synchronously, in this embodiment, the relay device monitoring center directly or indirectly instructs the relay device and the base station to switch the uplink and downlink time slots. In this embodiment, the TD-SCDMA system is taken as an example for description.

[0061] see figure 2 In this embodiment, the communication system includes a network management system (Network Management System, NMS) 201, a radio network controller operation and maintenance center (Operation & Maintenance Center-RNC, OMC-R) 202, a relay equipment monitoring center 203, a radio network controller (RadioNetwork Controller, RNC) 204, base stat...

Abstract

The invention discloses a method for sending changing information of time slot switching point and changing time slot switching point, which is used in relay devices to realize acquiring time slot switching point changing information and switching between uplink and downlink time slot synchronized with base station. The mentioned time slot switching point changing method includes: initiating changing of time slot switching point, and outputting time slot switching point information into operation maintenance channel to transmit; acquiring the mentioned time slot switching point changing information by monitoring center of the relay device, sending the time slot switching point changing information to the relay device, and distributing indications of changing time slot switching point to relay devices, in order to directly or indirectly indicating the relay device to carry out changing operation of time slot switching point; carrying out changing of time slot switching point according to indication from monitoring center of the relay device after receiving changing information of time slot switching point. The invention also discloses a relay device monitoring center, relay device and communication system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for sending time slot switching point change information and time slot switching point change. Background technique [0002] In the TD-SCDMA system, the radio frame includes two subframes, and each subframe is composed of several time slots connected according to a fixed timing structure. The first switching point in the subframe is between the downlink pilot (DwPTS) and the uplink pilot (UpPTS), which is the synchronization point of the entire system and is fixed; while the second switching point is between the uplink service and the downlink service between time slots, such as figure 1 As shown, between the service time slots TS3 and TS4, the location can be adjusted according to the needs of the service division, such as between the service time slots TS1 and TS2, usually, changing the time slot switching point means changing the second switching point point. ...
