Embodiment 1

[0090] This embodiment provides a cell reselection method, such as figure 1 As shown, this embodiment includes:

[0091] Step 101: The terminal receives a reselection configuration message sent by the network side, the reselection configuration message includes the first cell list and / or the second cell list, and the first trigger condition for reselecting to the first cell and / or or a second trigger condition for reselecting to a second cell;

[0092] Step 102: The terminal measures the signal strength of the measured cell, and obtains the measurement result;

[0093] Step 103: The terminal reselects to a second cell or a first cell according to the measurement result, the first trigger condition and / or the second trigger condition.

[0094] In this embodiment, the network side sends a reselection configuration message to the terminal, which includes the first cell list and / or the second cell list, and the first trigger condition for reselecting to the first cell and / or res...

Embodiment 2

[0180] This embodiment also provides a cell reselection method, such as figure 2 As shown, this embodiment includes:

[0181] Step 201: The network side sends a reselection configuration message to the terminal, the reselection configuration message includes a first cell list and / or a second cell list, and a first trigger condition for reselection to the first cell.

[0182] Wherein, the network side sending the reselection configuration message to the terminal includes:

[0183] The network side sends the reselection configuration message to all terminals under the network through a broadcast message, or sends the reselection configuration message to each terminal under the network through dedicated signaling.

Embodiment 3

[0185] This embodiment provides a cell reselection device, which is applied to a terminal, such as image 3 As shown, this embodiment includes:

[0186] The receiving module 31 is configured to receive a reselection configuration message issued by the network side, the reselection configuration message includes a first cell list and / or a second cell list, and a first trigger condition for reselection to the first cell and / or a second trigger condition for reselecting to a second cell;

[0187] The measurement module 32 is used to measure the signal strength of the measured cell to obtain the measurement result;

[0188] A reselection module 33, configured to reselect to a second cell or a first cell according to the measurement result, the first trigger condition and / or the second trigger condition.

[0189] In this embodiment, the network side sends a reselection configuration message to the terminal, which includes the first cell list and / or the second cell list, and the f...

Abstract

The invention provides a cell reselection method and apparatus, and belongs to the technical field of communication. The cell reselection method comprises the following steps: receiving, by a terminal, a reselection configuration message delivered by a network side, wherein the reselection configuration message comprises a first cell list and/or a second cell list, and a first trigger condition for reselecting to the first cell and/or a second trigger condition for reselecting to the second cell; performing, by the terminal, signal strength measurement on the measured cell to obtain a measurement result; and reselecting, by the terminal, to the second cell or the first cell according to the measurement result, the first trigger condition, and/or the second trigger condition. By adoption ofthe cell reselection method and apparatus, other terminals excluding a high speed railway passenger terminal can be prevented from residing in a high speed overlay network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell reselection method and device. Background technique [0002] In actual network deployment, in order to ensure the communication quality of passengers on high-speed railways, operators will deploy cells with special shapes (high-speed coverage cells) along the high-speed railways, so that there are high-speed coverage networks and ordinary networks along the high-speed railways. It can be deployed in the same frequency or different frequency. The ordinary network is used to provide services for users outside the vehicle; the high-speed overlay network is used to provide services for in-vehicle users. Different from the ordinary network, in order to compensate for the penetration loss of the vehicle body, the high-speed coverage network adopts some engineering methods to improve the signal penetration and coverage. As a result, non-passenger terminals along t...
