Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method, an apparatus, and a storage medium for adding or changing a conditional primary cell and a conditional secondary cell.
Background
Conditional Primary and Secondary Cell Addition or Change (CPAC) is a process in which a network side Primary node (MN) or Secondary Node (SN) sends a condition for adding or changing a Primary and Secondary Cell (PSCell) to a terminal in advance, and the terminal autonomously performs PSCell Addition or Change when measuring that a target PSCell meets the condition.

The present invention is described below with reference to scene embodiments.
The present embodiment provides a CPAC mechanism that can not activate PSCell immediately, where a network MN or SN configures a condition for adding or changing a primary cell and a secondary cell to a UE, and indicates whether the UE immediately activates a PSCell or activates time or a condition for activating the PSCell after discovering that a target PSCell meets the condition for adding or changing, so that dual connectivity can be quickly recovered on the premise of saving power consumption and signaling overhead of the UE, and a service with a high data rate is provided for the UE.
The implementation process of the embodiment includes:
the method comprises the following steps: the network side node MN or SN configures UE conditional primary and secondary cell addition or change (CPAC) information, such as: one or two of the items A3, A5, A4 and B1 and corresponding threshold values, the details can be found in the related art, and the details are not described herein; in addition, when the above content is configured, one or more of the following information may be indicated:
1) Finding a target PSCell that satisfies the conditions for addition or change, and then whether to activate the PSCell immediately; or, the time for activating the PSCell (e.g., a time offset from the time when the configuration information is received) may be the same for all candidate pscells or configured for per PSCell; or, a probability of activating the PSCell;
here, the MN or the SN may configure the time to activate the PSCell based on a determination of the characteristics of the UE traffic, such as: the MN or SN predicts that no high data rate traffic will arrive for the UE for a certain time, and therefore considers that the PSCell is not activated for this time.
The MN or SN may configure the probability of activating the PSCell based on a determination of the characteristics of the UE's previous traffic, such as: the MN or SN predicts that the UE will not have a high data rate traffic to arrive with a certain probability, and therefore considers that the PSCell will not be activated with a certain probability.
2) Whether the UE is allowed to actively initiate a request for activating the PSCell or not, if the UE is allowed to actively initiate the request for activating the PSCell, whether the request is initiated to the MN or the SN; for example: when the UE has an uplink service requirement, a request for activating the PSCell needs to be actively initiated;
3) The condition for activating the PSCell, such as the UE initiating a preset service, includes: in a special slice (e.g., ultra-reliable low-delay communication (URLLC)) service, the number of (uplink UL or downlink DL) data packets or data of the UE is greater than or not less than a first threshold; and/or the time delay of the data packet of the UE is larger than or not smaller than a second threshold value; and/or the arrival time or the duration of the service data with the packet length indicated by the service format information of the UE being greater than or not less than the third threshold, and the like.
Step two: the UE finds that a certain PSCell meets the conditions according to CPAC information configured by a network side node MN or an SN, and establishes RRC connection with the PSCell;
step three: the UE judges whether to activate the PSCell or not according to the indication information configured in the first step; specifically, one or more of the following may be included:
1) If the network side does not configure other indication information except the information of the CPAC, the PSCell is activated by default;
2) If the network side indicates that the PSCell is not (immediately) activated, the PSCell is in a deactivated state, that is, the UE does not monitor (monitor) the PDCCH, and RRM measurement can be relaxed;
3) If the network side configures the time for activating the PSCell, activating the PSCell (by initiating an activation request to the MN or the SN) at a time when the network requirement is met, and not activating before;
4) If the network side configures the probability P for activating the PSCell, randomly generating a random number P between 0 and 1 at the UE (the UE can generate the random number P after establishing RRC connection with the PSCell) and comparing the random number P with the probability P; if P is less than or not greater than the probability P, activating the PSCell, otherwise, not activating;
5) If the network side configures the condition for activating the PSCell, the UE determines whether the condition is satisfied, and if so, activates the PSCell.
Step four: and the UE reports that RRC connection is established with a certain target PSCell to the MN or the SN, and the state is activation or deactivation.
Optionally, the method may further include:
step five: if the UE needs to actively activate the PSCell due to service needs, an activation request is initiated to the MN or the SN according to the configuration of the network side; the activation request may carry the ID of the pre-activated PSCell, may also carry the reason for activation, etc.
In the embodiment of the present invention, after discovering that the target PSCell satisfies the addition or change condition, the UE may first establish a connection (e.g., RRC connection) with the PSCell, and then determine whether to activate the PSCell based on the activation indication information, so that the PSCell may be immediately activated when the service is needed, and the PSCell may not be activated when the service is not needed. Therefore, compared with the technology that the PSCell is added when the UE needs to perform double connection in the related technology and the time is very long (about tens of ms time delay), the embodiment of the invention can quickly recover the double connection (if the UE is directly activated on the basis of the RRC connection) on the premise of saving the power consumption and the signaling overhead of the UE, and can quickly provide the service with high data rate for the UE; compared with the technology that the PSCell cell is activated to carry out double connection immediately after the UE establishes RRC connection with the PSCell, the embodiment of the invention can save the power consumption of the UE under the scene that the UE does not need to carry out double connection immediately (because the power consumption of the double connection is larger than that of the single connection). .
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
