Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a Bypass Continuation Application of PCT/CN2020/126366, filed on Nov. 4, 2020, which claims priority to Chinese Patent Application No. 201911084329.X filed on Nov. 7, 2019, which are incorporated herein by reference in their entirety. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to the field of communications technologies, and in particular to a cell management method, a cell management configuration method, a terminal, and a network side device. 
     BACKGROUND 
     During random access, a terminal may perform a conditional handover between cells. That is, cells may be managed in a conditional trigger manner. During the conditional handover, a network side device sends configuration information for conditional handover to the terminal. The terminal may evaluate, according to the configuration information for conditional handover, whether candidate cells meet a condition. If the candidate cells meet the condition, the terminal may select a target cell to perform a handover. In the related art, a conditional handover is only applied to random access technology. For a scenario in which one terminal is connected to a plurality of (including two) cells, for example, dual connectivity (DC) and carrier aggregation (CA), a conditional handover solution in the related art is not applicable.

Exactly, use of the word “example” or “for example” or the like is intended to present a related concept in a specific manner. 
     The following describes the embodiments of the present disclosure with reference to the accompanying drawings. A cell management method and a cell management configuration method provided in the embodiments of the present disclosure are both applicable to a wireless communications system. The wireless communications system may be a 5th Generation (5G) system, an evolved long term evolution (eLTE) system, or a subsequent evolved communications system. 
       FIG. 1  is a structural diagram of a network system to which the embodiments of the present disclosure are applicable. As shown in  FIG. 1 , the network system includes a terminal  11  and a network side device  12 . The terminal  11  may be a user terminal or another terminal side device, for example, a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device. It needs to be noted that in the embodiments of the present disclosure, a specific type of the terminal  11  is not limited. The foregoing network side device  12  may be a 5G base station, or a base station of a later version, or a base station in another communications system, or referred to as a node, an evolved node, or a transmission reception point (TRP), or an access point (AP), or another word in the field. As long as the same technical effect is achieved, the network side device is not limited to a specific technical word. In addition, the network side device  12  may be a master node (MN) or a secondary node (SN). It needs to be noted that only a 5G base station is used as an example in the embodiments of the present disclosure, but a specific type of the network side device is not limited. 
       FIG. 2  is a flowchart of a cell management method according to an embodiment of the present disclosure. The method is applied to the network system shown in  FIG. 1 . As shown in  FIG. 2 , the method includes the following steps. 
     Step  201 : A network side device sends configuration information to a terminal. 
     The configuration information includes cell management configuration information and a triggering condition group corresponding to the cell management configuration information, the triggering condition group includes N triggering conditions associated with M cells, each cell of the M cells is associated with at least one triggering condition of the N triggering conditions, the configuration information is used for managing the M cells by the terminal, M is greater than 1, and N is greater than or equal to 1. 
     It should be noted that L (L is greater than or equal to M) cells may be configured in the cell management configuration information. The L cells include the foregoing M cells. That is, in addition to the foregoing M cells, more cells may be configured in the cell management configuration information. 
     The M cells may be a serving cell or a non-serving cell. The non-serving cell may include a neighboring cell. The serving cell may be a serving cell currently configured for use by the terminal, for example, a primary cell (PCell), a primary secondary cell (PSCell), or a secondary cell (SCell). 
     There may be a plurality of association relationships between the N triggering conditions in the foregoing triggering condition group and the foregoing M cells, as long as it is ensured that each cell is associated with at least one triggering condition. To better understand association relationships between the N triggering conditions in the foregoing triggering condition group and the foregoing M cells, examples are provided below for description. 
     For example, it is assumed that the foregoing M cells include a cell a and a cell b, the foregoing triggering condition group includes a plurality of triggering conditions, some (one or more) triggering conditions in the plurality of triggering conditions are associated with the cell a, and some (one or more) triggering conditions are associated with the cell b. That is, any cell may be associated with one triggering condition or may be associated with a plurality of triggering conditions. One triggering condition in the foregoing triggering condition group may be associated with the cell a and the cell b. For example, one triggering condition in the foregoing triggering condition group is that measured signal quality of a neighboring cell is greater than a threshold. If the triggering condition is associated with the cell a, the neighboring cell is the cell a. If the triggering condition is associated with the cell b, the neighboring cell is the cell b. 
     Step  202 : The terminal receives the configuration information. 
     Step  203 : The terminal manages the M cells according to the configuration information. 
     In the embodiments of the present disclosure, a triggering condition group used for cell management is configured for a terminal, and one or more triggering conditions associated with a plurality of cells are configured in the triggering condition group. In this way, the terminal can manage the plurality of associated cells according to the triggering conditions in the triggering condition group. Because the terminal can manage the plurality of cells, the cell management method in the embodiments of the present disclosure is applicable to a multi-cell connection scenario, so that the terminal can implement a conditional handover between cells in the multi-cell connection scenario. 
     In addition, in the embodiments of the present disclosure, the terminal can manage the plurality of cells by using triggering conditions. Therefore, during a conditional handover between cells in a multi-cell connection scenario, it can be ensured that the terminal selects a cell with relatively high signal quality for the conditional handover between cells, thereby ensuring the channel quality after the terminal is handed over between cells. In this way, in one aspect, the communication performance after the terminal is handed over between cells can be improved, and in another aspect, a waste of a reserved resource of a cell due to a failure in normal use because of excessively low channel quality of the cell after the handover can be avoided. 
     Optionally, the cell management configuration information includes dual connectivity configuration information or carrier aggregation configuration information. 
     In the related art, the multi-cell connection scenario includes a dual connectivity scenario and a carrier aggregation scenario. Therefore, the cell management solution provided in the embodiments of the present disclosure is applicable to a conditional handover between cells in dual connectivity and is also applicable to a conditional handover between cells in carrier aggregation. 
     In the embodiments of the present disclosure, the network side device may use the cell management configuration information to configure a conditional handover between cells in dual connectivity or carrier aggregation for the terminal. In some examples, the cell management configuration information may include dual connectivity configuration information, and the network side device uses the dual connectivity configuration information to configure a conditional handover between cells in dual connectivity for the terminal. Alternatively, the cell management configuration information may include carrier aggregation configuration information, and the network side device uses the carrier aggregation configuration information to configure a conditional handover between cells in carrier aggregation for the terminal. 
     For example, the network side device configures a triggering condition group. The triggering condition group includes a triggering condition a and a triggering condition b. The triggering condition group corresponds to one piece of handover configuration signaling (for example, RRCReconfig). The handover configuration signaling includes dual connectivity configuration information. One target PCell and one target PSCell are configured in the handover configuration signaling. The handover configuration signaling may additionally further include a plurality of target SCells. The network side device may configure that the triggering condition a is associated with the target PCell and the triggering condition b is associated with the target PSCell. 
     Optionally, the cell management configuration information is used for indicating at least one of the following: 
     performing a handover on a PCell; 
     performing addition, alteration, deletion or modification on a PSCell; or 
     performing addition, alteration, deletion or modification on an SCell. 
     Optionally, the M cells include at least an active cell. 
     For example, the foregoing M cells include a PCell or an active PSCell and further include an inactive SCell. For example, the triggering condition a is associated with the PCell or the active PSCell, and the triggering condition b is associated with the inactive SCell. 
     In this way, it can be ensured that after the terminal is handed over between cells, at least one active cell is available for use by the terminal, thereby ensuring the communication performance of the terminal in dual connectivity or carrier aggregation. 
     Optionally, the M cells do not include at least one of an inactive cell, a cell configured with a dormant function, or a cell configured with a suspend function. 
     For example, the foregoing M cells do not include an inactive SCell or an SCell configured with a dormant function. The M cells do not include an inactive PSCell, a PSCell configured with a dormant function, or a PSCell configured with a suspend function. 
     In this way, it can be ensured that after the terminal is handed over between cells, an active cell is available for use by the terminal, thereby ensuring the communication performance of the terminal in dual connectivity or carrier aggregation. 
     Optionally, the M cells are all active cells. 
     For example, the foregoing M cells include a PCell and further include a PSCell in an active state or an SCell in an active state. 
     In this way, it can be ensured that after the terminal is handed over between cells, an active cell is available for use by the terminal, thereby ensuring the communication performance of the terminal in dual connectivity or carrier aggregation. 
     A dual connectivity application scenario and a carrier aggregation application scenario are separately combined to use a plurality of embodiments below to describe the cell management method in the embodiments of the present disclosure below in detail. 
     Embodiment 1 
     The cell management configuration information includes dual connectivity configuration information. The triggering condition group includes a first triggering condition associated with a first PCell (a primary cell PCell of a primary cell group), and the triggering condition group further includes a second triggering condition associated with a first PSCell. Optionally, an initial state of the first PSCell may be an active state. 
     In an example, the first triggering condition may be: measured signal quality of the first PCell is higher (or not lower) than measured signal quality of a source PCell, or measured signal quality of the first PCell is higher (or not lower) than a threshold T 1 . The second triggering condition may be: measured signal quality of the first PSCell is higher (or not lower) than a threshold T 2 . 
     In the embodiment, according to whether the first triggering condition is satisfied and whether the second triggering condition is satisfied, the terminal may use one of the following manners to manage the first PCell and the first PSCell. Details are as follows. 
     Manner 1: In a case that both the first triggering condition and the second triggering condition are satisfied, connect to the first PCell and the first PSCell. 
     In this manner, both the first triggering condition and the second triggering condition are satisfied, both the first PCell and the first PSCell have relatively high channel quality, and both the first PCell and the first PSCell are available for use by the terminal in a dual connectivity scenario. Therefore, the terminal may connect to the first PCell and the first PSCell. 
     Manner 2: In a case that the first triggering condition is satisfied and the second triggering condition is not satisfied, connect to the first PCell, and set the first PSCell to an inactive state or suspend the first PSCell or set the first PSCell to a dormant working mode or delete the first PSCell or delete a secondary cell group SCG corresponding to the first PSCell. 
     In this manner, the first triggering condition is satisfied, the first PCell has relatively high channel quality, and the first PCell is available for use by the terminal in a dual connectivity scenario. Therefore, the terminal may connect to the first PCell. The second triggering condition is not satisfied, and the first PSCell has relatively low channel quality. To avoid occupying a reserved resource of the first PSCell, the terminal may set the first PSCell to an inactive state or suspend the first PSCell or set the first PSCell to a dormant working mode or delete the first PSCell or delete a secondary cell group (SCG) corresponding to the first PSCell. 
     Embodiment 2 
     The cell management configuration information includes carrier aggregation configuration information. The triggering condition group includes a third triggering condition associated with a first special cell (SpCell). The triggering condition group further includes a fourth triggering condition associated with a first SCell. The first SpCell may be a PCell or may be a PSCell. Optionally, an initial state of the first SCell may be an active state. 
     In an example, the first SpCell is a second PCell, and the third triggering condition may be: measured signal quality of the second PCell is higher (or not lower) than measured signal quality of a source PCell, or measured signal quality of the second PCell is higher (or not lower) than a threshold T 1 . The fourth triggering condition may be: measured signal quality of the first PCell is higher (or not lower) than a threshold T 2 . 
     The foregoing measured signal quality may include a reference signal received power (RSRP), reference signal received quality (RSRQ), or a signal-to-interference-plus-noise ratio (SINR), and the like. 
     In the embodiment, according to whether the third triggering condition is satisfied and whether the fourth triggering condition is satisfied, the terminal may use one of the following manners to manage the first SpCell and the first SCell. For example: 
     Manner 1: In a case that both the third triggering condition and the fourth triggering condition are satisfied, connect to the first SpCell and the first SCell. 
     In this manner, both the third triggering condition and the fourth triggering condition are satisfied, both the first SpCell and the first SCell have relatively high channel quality, and both the first SpCell and the first SCell are available for use by the terminal in a carrier aggregation scenario. Therefore, the terminal may connect to the first SpCell and the first SCell. 
     Manner 2: In a case that the third triggering condition is satisfied and the fourth triggering condition is not satisfied, connect to the first SpCell, and set the first SCell to an inactive state or suspend the first SCell or set the first SCell to a dormant working mode or delete the first SCell. 
     In this manner, the third triggering condition is satisfied, the first SpCell has relatively high channel quality, and the first SpCell is available for use by the terminal in a carrier aggregation scenario. Therefore, the terminal may connect to the first SpCell. The fourth triggering condition is not satisfied, and the first SCell has relatively low channel quality. To avoid occupying a reserved resource of the first SCell, the terminal may set the first SCell to an inactive state or suspend the first SCell or set the first SCell to a dormant working mode or delete the first SCell. 
     Embodiment 3 
     The cell management configuration information includes carrier aggregation configuration information. The triggering condition group includes a fifth triggering condition associated with a second SCell. The triggering condition group further includes a sixth triggering condition associated with a third SCell. Initial states of the second SCell and the third SCell may both be active states. 
     In an example, the fifth triggering condition may be: measured signal quality of the second PCell is higher (or not lower) than a threshold T 1 . The sixth triggering condition may be: measured signal quality of the third PCell is higher (or not lower) than a threshold T 2 . 
     In the embodiment, according to whether the fifth triggering condition is satisfied and whether the sixth triggering condition is satisfied, the terminal may use one of the following manners to manage the second SCell and the third SCell. For example: 
     Manner 1: In a case that both the fifth triggering condition and the sixth triggering condition are satisfied, connect to the second SCell and the third SCell. 
     In this manner, both the fifth triggering condition and the sixth triggering condition are satisfied, both the second SCell and the third SCell have relatively high channel quality, and both the second SCell and the third SCell are available for use by the terminal in a carrier aggregation scenario. Therefore, the terminal may connect to the second SCell and the third SCell. 
     Manner 2: In a case that the fifth triggering condition is satisfied and the sixth triggering condition is not satisfied, connect to the second SCell, and set the third SCell to an inactive state or suspend the third SCell or set the third SCell to a dormant working mode or delete the third SCell. 
     In this manner, the fifth triggering condition is satisfied, the second SCell has relatively high channel quality, and the second SCell is available for use by the terminal in a carrier aggregation scenario. Therefore, the terminal may connect to the second SCell. The sixth triggering condition is not satisfied, and the third SCell has relatively low channel quality. To avoid occupying a reserved resource of the third SCell, the terminal may set the third SCell to an inactive state or suspend the third SCell or set the third SCell to a dormant working mode or delete the third SCell. 
     For Manner 2 in the foregoing Embodiment 1 to Embodiment 3, the terminal may further report status information of related cells to the network side device (reference may be made to the following optional implementations for details) for the network side device to learn the status information of the related cells, and resources corresponding to the related cells are provided for use by other terminals, to avoid a waste of reserved resources of the related cells. 
     Optionally, in a case that the terminal sets the first PSCell to the inactive state or suspends the first PSCell or sets the first PSCell to the dormant working mode or deletes the first PSCell, the terminal reports status information of the first PSCell to the network side device. 
     Optionally, in a case that the terminal deletes the SCG corresponding to the first PSCell, the terminal reports status information of the SCG corresponding to the first PSCell to the network side device. 
     Optionally, in a case that the terminal sets the first SCell to the inactive state or suspends the first SCell or sets the first SCell to the dormant working mode or deletes the first SCell, the terminal reports status information of the first SCell to the network side device. 
     Optionally, in a case that the terminal sets the third SCell to the inactive state or suspends the third SCell or sets the third SCell to the dormant working mode or deletes the third SCell, the terminal reports status information of the third SCell to the network side device. 
     In combination with the foregoing implementations, in the embodiments of the present disclosure, a triggering condition group used for cell management is configured for a terminal, and one or more triggering conditions associated with a plurality of cells are configured in the triggering condition group. In this way, the terminal can manage the plurality of associated cells according to the triggering conditions in the triggering condition group. Because the terminal can manage the plurality of cells, the cell management method in the embodiments of the present disclosure is applicable to a multi-cell connection scenario, so that the terminal can implement a conditional handover between cells in the multi-cell connection scenario.
