Problems solved by technology

[0003] During the research and practice of the prior art, the inventors of the present invention found that when a large number of terminals are switched from one base station to another base station at the same time, for example, all terminals connected to a relay node installed on a high-speed train Terminals, as the train passes through multiple cells at high speed, multiple terminals on the train will basically send measurement reports to the source base station at the same time, so there will be a large number of air interface signaling in a short period of time, and the source base station will send measurement reports in a short period of time. There is simply no time to process these large amounts of air interface signaling within the time, so that some terminals have left the original service area before they have time to perform handover to the target base station. At this time, the terminal does not access any cell, and the service of the terminal is interrupted.

Embodiment 1

[0028] figure 1 It is a flow chart of the handover method provided by Embodiment 1 of the present invention.

[0029] Detailed instructions are as follows:

[0030] Step 101, receiving a measurement report sent by a node device;

[0031] Step 102, sending to the target base station a handover request of all terminals under the node device or all terminals connected to the access area of ​​the node device;

[0032] Step 103, instructing all terminals under the node device or all terminals connected to the area where the node device is connected to perform handover.

Embodiment 2

[0034] In this embodiment, the handover method provided by the embodiment of the present invention is described by taking the node device as a relay node or a terminal under the relay node as an example.

[0035] figure 2 It is a flow chart of the handover method provided by Embodiment 2 of the present invention.

[0036] Step 201, the source base station assigns group identifiers to all terminals connected to the node device;

[0037] The source base station allocates a group identifier for the terminal connected to the relay node. Specifically: after the terminal accesses the relay node, it reports the ID of the relay node to the source base station through the relay node, and the source base station assigns a group ID to the terminal according to the ID of the relay node, and accesses the same relay node. The terminals under the node are assigned the same group ID, and multiple group IDs may be assigned to the terminals under the same relay node as required, which is not...

Embodiment 3

[0055] In this embodiment, a scenario in which a terminal in the same sector under the source base station is handed over to the target base station is taken as an example to illustrate the handover method provided by the embodiment of the present invention. In order to form continuous coverage between base stations or between a base station and a fixed relay, the coverage area of ​​a base station is divided into several sectors, and a certain fixed sector forms continuous coverage with another base station or a fixed relay. For example: the source base station has two sectors, and the second sector is specially configured to form continuous coverage with the target base station of the coverage tunnel. Generally, a large number of fast-moving terminals will handover from the first sector of the source base station to the second sector, and handover from the second sector to the target base station covering the tunnel.

Abstract

The invention discloses a switching method. The method comprises the following steps: receiving a measurement report sent by a node device; sending the switching requests of all the terminals under the node device or the switching requests of all the terminals accessing to the access area of the node device to a target base station; and indicating all the terminals under the node device or all the terminals accessing to the access area of the node device for switching. The embodiment of the invention also provides a corresponding base station and a switching system. The invention can improve the efficiency of the simultaneous switching of multiple terminals.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a switching method and a related device. Background technique [0002] In current mobile communication systems, in order to maintain service continuity, a handover operation is performed when a mobile terminal moves from the coverage of one base station to the coverage of another base station. The existing handover process is specifically: the terminal sends a measurement report to the base station of the source cell, and the measurement report carries information such as the terminal identifier and monitored signal parameters; Send a handover request, carrying the context information of the terminal; after the access control of the base station of the target cell, the base station of the source cell sends handover parameters to the terminal, and the terminal performs synchronization and random access operations to the base station of the target cell accord...
