For a better understanding, the following explanation is made on related concepts that may be involved in the embodiments of the present application.

Multi-card UE:

a multi-card UE refers to a UE with more than one subscriber identity (Subscriber Identity Module, SIM) card installed. Taking dual-card UE as an example, the dual-card UE may be classified into single-transmission single-reception, single-transmission dual-reception, and dual-transmission dual-reception UEs according to whether the UE supports simultaneous transmission or reception in a network of two cards.

Single-shot single-receive UE: the UE implementation (e.g., dual cards share the same set of hardware or radio frequency) results in the UE being able to send and receive information alternately over the network of two cards only by means of time division.

Single-shot dual-reception UE: the UE can only transmit uplink in the network of two cards alternately in a time division manner, but supports downlink reception in the network of two cards at the same time.

Dual-transmit dual-receive UE: the UE supports both uplink and downlink reception on the network of both cards.

Transient capability limitation (Temporary Capability restriction):

currently, for a dual-transmit dual-receive multi-card UE, each card uses a separate hardware module to support simultaneous reception and transmission. However, this method has problems such as low hardware utilization efficiency and high cost. For this reason, 3GPP Rel-18 will study how to support dynamic capability segmentation of dual card UEs across dual card networks with dual card shared portions of the hardware modules. For example, when card a is in the connected state, card B is in the disconnected state, and the capabilities of the UE are occupied by card a. If card B is about to establish or restore a radio resource control (Radio Resource Control, RRC) connection, it is necessary to cut part of the capability of card a to card B, and at this time, the UE needs to indicate a short capability limited state to network a (i.e. there is a part of capability to be used for other cards), otherwise the UE may lose data of network a or cause a problem such as network resource waste.

The UE indicates to the network side a short capability limitation, which may be a state where some radio capabilities of the UE are not supported for a short period of time, or may be a state where the UE does not change radio capabilities but is implemented by requesting or indicating to the network side that some functions/resources are disabled. For example, when a dual-card UE is configured with dual connections (Dual Connectivity, DC) in network a in a connected state, the secondary cell group (Secondary Cell Group, SCG) is in an active state. If the UE is to initiate RRC connection establishment at network B at this time, the multi-card UE may request suspension/deactivation of SCG at network a.

During RRC INACTIVE state or when initiating RRC connection recovery, the UE in RRC INACTIVE (INACTIVE) state does not have consistent UE capability in an Access Stratum (AS) context stored in the base station side, so that the network side may send a configuration exceeding the UE capability to the UE in the RRC connection recovery process, which results in abnormal transmission of the UE.

The UE capability control method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of a UE capability control method according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:

Step 201, the UE receives first indication information, where the first indication information is used to indicate at least one of the following:

carrying out self-adaptive transmission on the multiple USIM cards UE;

the UE is scheduled with a first target UE capability.

The target state is that the UE capability of the UE is inconsistent with the second target UE capability when the UE initiates the RRC connection recovery procedure, and the target behavior includes at least one of:

changing the UE capability of the UE in an RRC inactive state;

changing the UE capability of the UE in an RRC connection recovery process;

It should be noted that, the method provided in the embodiment of the present application is applied to a terminal, where the terminal is a Multi-card terminal, that is, the terminal is a Multi-global subscriber identity (Multi-Universal Subscriber Identity Module, MUSIM) communication device, in this case, the UE is a UE corresponding to one USIM card of the Multi-card terminal, and the UE capability is a capability corresponding to a UE of one USIM card. For example, the UE includes a USIM card 1 and a USIM card 2, when the USIM card 1 (i.e., the target USIM card) is in a connected state, i.e., the USIM card 1 accesses the corresponding network 1, the UE capability is also the UE capability corresponding to the USIM card 1. For an understanding of the UE and the UE capability in the following embodiments, reference may be made to the explanation here, and details are not repeated.

The first indication information is used for indicating whether the network side equipment allows or supports the UE to execute the target behavior or enter the target state. For example, the first indication information may be information indicating that the network side device allows the UE to enter the target state, that is, allows the UE to have a capability inconsistent with a second target UE capability when the UE initiates the RRC connection recovery procedure, for example, the second target UE capability may be a UE capability saved by the network side device.

Or, the first indication information may also indicate whether the network side device supports the UE to perform the target behavior, for example, the first indication information indicates whether the network side device supports the UE to change the capability of the UE in the RRC inactive state, or indicates whether the UE to change the capability of the UE in the RRC connection recovery procedure, or indicates whether the UE to report the capability of the UE after entering the RRC connection state, or so on, which is not listed herein too much.

Still alternatively, the first indication information may also be an indication of whether the network side device supports the first operation, for example, an indication of whether the network side device supports adaptive transmission according to a target behavior or a target state of the UE, or an indication of whether the network side device supports adaptive transmission on a global subscriber identity (Universal Subscriber Identity Module, USIM) card UE, or an indication of whether the network side device can schedule the UE with the first target UE capability, which is not excessively listed herein.

The adaptive transmission may be understood as a failure occurring when the network side device schedules the UE in a first configuration, where the first configuration exceeds the current UE capability of the UE, and the network side device may adjust to a second configuration, where the second configuration is lower than the first configuration to attempt to schedule the UE. This adaptive transmission may be understood as that the abnormality of the network side device occurring on the terminal side may be interpreted as a result of the UE performing the target behavior or the target state, so that reasonable network measures are taken.

It should be noted that, when the target behavior is that the UE reports the UE capability of the UE after the UE enters the RRC connected state, it may be understood that the UE triggers reporting of the UE capability immediately after the UE enters the RRC connected state.

In this embodiment of the present application, the scheduling the UE with the first target UE capability includes:

and under the condition that the network side equipment fails to schedule the UE, the UE is scheduled with the first target UE capability.

It may be appreciated that if the network side device fails to schedule the UE, which may be caused by the mismatch between the UE capability stored by the network side device and the UE capability currently used by the UE, the network side device schedules the UE with the first target UE capability. Optionally, the first target UE capability may be a UE capability defaulted by the network side device, for example, may be a set of UE capabilities that the UE has recently reported, so as to ensure that the network side device can implement scheduling of the UE.

Optionally, the first target UE capability includes at least one of:

the UE capability reported by the UE last time;

default UE capabilities reported by the UE;

the UE capability corresponding to the UE in the RRC idle state;

protocol-specified UE capabilities.

For example, the first target UE capability is the UE capability that the UE has recently reported, and the first indication information may be used to indicate whether the network side device supports scheduling the UE with the UE capability that the UE has recently reported.

Or, the first target capability is a UE capability corresponding to the UE in the RRC idle state, and the first indication information may be used to indicate whether the network side device supports scheduling the UE with the UE capability corresponding to the UE in the RRC idle state.

It may be appreciated that the first target UE capability may also be the other possible situations described above, and the specific content indicated by the first indication information may also be other possible situations, which are not listed here.

Optionally, the second target UE capability includes at least one of:

UE capabilities saved by the UE during RRC inactive state;

the UE capability of the UE is stored by the network side equipment;

the UE capability reported to the network side equipment by the UE last time;

And the UE is the last time the UE capability confirmed by the network side equipment.

For example, the second UE capability is a UE capability stored by the UE during the RRC inactive state, and the first indication information may be used to indicate whether the network side device allows the UE to enter the target state, that is, whether the UE is allowed to initiate the RRC connection recovery procedure, where the UE capability is inconsistent with the UE capability stored by the UE during the RRC inactive state.

Or, the second UE capability is the UE capability that is reported to the network side device by the UE last time, and the first indication information may be used to indicate whether the network side device allows the UE to initiate the RRC connection recovery procedure, where the UE capability is inconsistent with the UE capability that is reported to the network side device by the UE last time.

In this embodiment of the present application, the UE receives first indication information, where the first indication information is used to indicate whether the network side device allows or supports the UE to perform the target behavior or enter the target state, and/or is used to indicate whether the network side device supports the first operation. In this way, the UE can execute related operations on the UE capability based on the first indication information, so as to match with the actions or operations allowed or supported by the network side device, so as to ensure that the network side device does not send a configuration exceeding the UE capability to the UE, thereby avoiding abnormal transmission between the UE and the network side device, and ensuring smooth transmission between the UE and the network side device.

Optionally, the UE receiving the first indication information includes at least one of:

the UE acquires the first indication information from a broadcast message;

the UE acquires the first indication information from the special signaling.

For example, the UE may acquire the first indication information through a system message; alternatively, the UE may acquire the first indication information through dedicated signaling, e.g., the dedicated signaling may be an RRC release message, etc.

Optionally, the method further comprises:

and under the condition that the UE is released to an RRC inactive state by the network side equipment, acquiring an RRC release message sent by the network side equipment, wherein the RRC release message indicates the first indication information of at least one cell.

That is, when the UE is released to the RRC inactive state by the network side device, the network side device may indicate at least one cell capable of supporting the UE to perform the target action or enter the target state, or supporting the network side device to perform the first operation in the RRC release message. For example, the RRC release message may indicate that the UE may change the capability of the UE in the RRC connection recovery procedure when the supporting UE initiates the RRC connection recovery procedure. Of course, other conditions may be indicated in the RRC release message, which are not listed here too much. In this embodiment of the present application, the UE may determine, based on the RRC release message, which cells may perform the actions or operations indicated by the first indication information, so as to better manage the actions of the UE.

Optionally, the method further comprises:

the UE executes a first behavior under the condition that the first indication information is not received or the first indication information indicates that network side equipment does not allow or support the UE to execute the target behavior;

wherein the first behavior comprises at least one of:

reselecting to a cell that allows or supports the UE to perform the target behavior;

entering an RRC idle state;

switching back the capability of the UE from other USIM cards;

not executing the target behavior;

the target state is not entered.

For example, the first indication information indicates that the network side device does not support the UE to perform the target behavior, the UE may reselect to a cell supporting or allowing the UE to perform the target behavior, or the UE enters an RRC idle state, or the UE does not perform the target behavior, or the like.

It should be noted that, in this embodiment of the present application, the UE is a multi-card UE, and in this case, the UE establishes an RRC connection with the network side device, which means that the UE establishes an RRC connection based on one of USIM cards (e.g., the first USIM card) and the network side device corresponding to the one of USIM cards, and the capability of the UE is that of the UE corresponding to the first USIM card. For example, the UE includes a USIM card 1 and a USIM card 2, and when the USIM card 1 is in a connected state, that is, the USIM card 1 accesses the corresponding network 1, the UE capability is also referred to as a UE capability corresponding to the USIM card 1. If the first action includes switching back the capability of the UE from the other USIM cards, for example, when the UE accesses the corresponding network 1 based on the USIM card 1, the first action may refer to switching back the corresponding UE capability from the USIM card 2, so as to improve the UE capability of the USIM card 1.

In an embodiment of the present application, the method further includes:

the first indication information indicates that the UE performs at least one of the following under the condition that the network side device allows or supports the UE to perform the target behavior:

executing the target behavior or entering the target state;

and after entering the RRC connection state, reporting the UE capability of the UE to network side equipment.

It may be appreciated that, if the first indication information indicates that the network side device allows or supports the UE to perform the target behavior, the UE may perform the target behavior or enter the target state based on the first indication information. The target behavior and the target state may be described in the foregoing embodiments, and are not described herein.

Or if the first indication information indicates that the network side equipment allows or supports the UE to execute the target behavior, the UE can report the UE capability of the UE to the network side equipment after entering an RRC connection state, and further the network side equipment can timely acquire the UE capability currently used by the UE, so that the network side equipment can send configuration matched with the UE capability to the UE so as to ensure smooth transmission between the UE and the network side equipment.

Optionally, the reporting the UE capability of the UE to the network side device includes:

And after receiving the UE capability request message sent by the network side equipment, the UE reports the UE capability of the UE to the network side equipment.

It may be understood that, if the first indication information indicates that the network side device allows or supports the UE to execute the target behavior, after the UE enters the RRC connected state, the UE may report the UE capability to the network side device after receiving the UE capability request message sent by the network side device.

According to the technical scheme provided by the embodiment of the invention, the UE can execute related operation on the UE capability based on the first indication information, so that the UE is matched with the behavior or operation allowed or supported by the network side equipment, the network side equipment is ensured not to send configuration exceeding the UE capability to the UE, and smooth transmission between the UE and the network side equipment is ensured.
