Embodiment 1

[0062] The cell management configuration information includes dual connectivity configuration information, the trigger condition group includes a first trigger condition associated with the first PCell (the primary serving cell of the primary cell group), and the trigger condition group further includes a second trigger condition associated with the first PSCell. Further, the initial state of the first PSCell may be an activated state.

[0063] As an example, the first trigger condition may be: the measurement signal quality of the first PCell exceeds (or is not lower than) the measurement signal quality of the source PCell, or the measurement signal quality of the first PCell exceeds (or is not lower than) a threshold value T1. The second trigger condition may be: the measured signal quality of the first PSCell exceeds (or is not lower than) the threshold value T2.

[0064] In this embodiment, the terminal may manage the first PCell and the first PSCell in one of the followi...

Embodiment 2

[0070] The cell management configuration information includes carrier aggregation configuration information, the trigger condition group includes a third trigger condition associated with the first SpCell (Special Cell, special cell), and the trigger condition group further includes a fourth trigger condition associated with the first SCell. The first SpCell may be a PCell or a PSCell. Further, the initial state of the first SCell may be an activated state.

[0071] As an example, the first SpCell is the second PCell, and the third trigger condition may be: the measured signal quality of the second PCell exceeds (or is not lower than) the measured signal quality of the source PCell, or the measured signal quality of the second PCell exceeds ( or not lower than) the threshold value T1. The fourth trigger condition may be: the measured signal quality of the first SCell exceeds (or is not lower than) the threshold value T2.

[0072] The above-mentioned measured signal quality m...

Embodiment 3

[0079] The cell management configuration information includes carrier aggregation configuration information, the trigger condition group includes a fifth trigger condition associated with the second SCell, and the trigger condition group further includes a sixth trigger condition associated with the third SCell. Wherein, the initial states of the second SCell and the third SCell can both be activated states.

[0080] As an example, the fifth trigger condition may be: the measured signal quality of the second SCell exceeds (or is not lower than) the threshold value T1. The sixth trigger condition may be: the measured signal quality of the third SCell exceeds (or is not lower than) the threshold value T2.

[0081] In this embodiment, the terminal may manage the second SCell and the third SCell in one of the following manners according to the satisfaction of the fifth trigger condition and the sixth trigger condition. details as follows:

[0082] Manner 1: Connect to the second...

Abstract

The present invention provides a cell management method, a cell management configuration method, a terminal and a network side device, wherein the cell management method includes: receiving configuration information sent by the network side device, the configuration information includes cell management configuration information, and a A trigger condition group corresponding to the cell management configuration information, the trigger condition group includes N trigger conditions associated with M cells, each of the M cells and at least one trigger condition in the N trigger conditions association, the M is greater than 1, and the N is greater than or equal to 1; the M cells are managed according to the configuration information. In this way, the terminal can implement the conditional handover of cells in a multi-cell connection scenario.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a cell management method, a cell management configuration method, a terminal and a network side device. Background technique [0002] During random access, the terminal can switch cells conditionally, that is, it can manage cells in a condition-triggered manner. During the conditional handover process, the network side device sends the configuration information of the conditional handover to the terminal, and the terminal can evaluate whether the candidate cell satisfies the condition according to the conditional handover configuration information. If the condition is satisfied, the terminal can select a target cell for handover. At present, conditional handover is only applied to random access technology. For scenarios where the terminal is connected to multiple (including two) cells, such as DC (Dual Connectivity, dual connectivity), CA (Carrier Aggregatio...
