Embodiment 1

[0069] The terminal device acquires an identifier of at least one CAG cell and / or an identifier of at least one CAG frequency point that has been accessed and / or attempted to be accessed before.

[0070] In an implementation manner, the terminal device may acquire an identifier of at least one CAG cell and / or an identifier of at least one CAG frequency point accessed before and / or attempted to access before according to the saved information.

[0071] Optionally, the terminal device may obtain the saved information through system information or dedicated signaling. Exemplarily, the dedicated signaling may carry redirection information or cell reselection priority information in a radio resource control (Radio Resource Control, RRC) connection release message.

[0072] For example, when the terminal device is in a cell that has been accessed before, it determines whether the cell is a CAG cell by reading the system information of the cell. If the cell is a CAG cell, the termin...

Embodiment 2

[0087] The terminal device can acquire the identifier of at least one CAG cell and / or the identifier of at least one CAG frequency point through the system information broadcast by the CAG cell.

[0088] Optionally, the system information may include at least one of the following information: an index of at least one CAG frequency point, a PCI range corresponding to at least one CAG frequency point, a PCI identifier corresponding to at least one CAG frequency point, at least one CAG identifier, and at least An identifier of a CAG frequency point.

[0089] The CAG frequency point may be the CAG frequency point of the current frequency point, and the PCI or PCI range corresponding to the CAG frequency point may be the PCI or PCI range of the CAG cell supported by the current frequency point. At this time, the system information may be carried in a system information block 3 (SystemInformation Block 3, SIB3).

[0090] The CAG frequency point may also be a CAG frequency point of ...

Embodiment 3

[0136] During the redirection process, the terminal device may receive redirection information, where the redirection information may indicate at least one CAG cell identifier and / or at least one CAG frequency point identifier. The terminal device can acquire at least one CAG cell identifier and / or at least one CAG frequency point identifier through the redirection information.

[0137] Optionally, the redirection information may include at least one of the following identifiers: an index of at least one CAG frequency, a PCI identifier corresponding to each CAG frequency in at least one CAG frequency, at least one CAG cell identifier, and at least one frequency The ID of the point. Wherein, the CAG cell identity may be PLMN and CAG identity. Wherein, the PCI identifier may also be a PCI index or a PCI range.

[0138] Optionally, the redirection information may be carried in RRC dedicated signaling. For example, the redirection information is carried in the RRC connection re...

Abstract

An embodiment of the invention relates to a cell selection method, terminal equipment and network equipment. The method comprises the steps that: terminal equipment acquiring an identifier of at least one cell and / or an identifier of at least one frequency point corresponding to a network type supported by the terminal equipment; and the terminal equipment determines a target cell for cell selection or cell reselection according to the identifier of the at least one cell and / or the identifier of the at least one frequency point. According to the cell selection method, the terminal equipment and the network equipment provided by the embodiment of the invention, the probability that the terminal equipment selects an appropriate cell can be improved when the terminal equipment performs cell selection or cell reselection, so that the normal service transmission of the terminal equipment and the performance of the terminal equipment are ensured.

Description

[0001] This application is an invention patent with the Chinese application number 201980090237.4 (corresponding to the PCT international application number PCT / CN2019 / 102363), the application date is August 23, 2019, and the invention name is "Cell Selection Method, Terminal Equipment and Network Equipment" Divisional application of the application. technical field [0002] The present application relates to the communication field, and specifically relates to a cell selection method, terminal equipment and network equipment. Background technique [0003] In a wireless communication system, a terminal device can perform cell selection or cell reselection. Currently, when a terminal device performs cell selection or cell reselection, the terminal device only selects the strongest cell on the frequency point. [0004] However, the cell supported by the terminal device may not be the strongest cell on this frequency point, so the terminal device may not be able to select a su...
