In some embodiments, the embodiments of the present application can be applied to multi-card terminals. Multi-card terminals refer to terminals with more than one USIM card installed. Taking dual-SIM terminals as an example, dual-SIM terminals can be divided into single-send and single-receive, single-send and dual-receive, and dual-send and dual-receive terminals depending on whether the terminal supports simultaneous transmission or reception on the network of two cards.

Single-sending and single-receiving terminal: The terminal can only send and receive information alternately on the two card networks through time division.

Single-transmitting and dual-receiving terminal: The terminal can only alternately transmit uplink on the two card networks through time division, but supports downlink reception on the two card networks at the same time.

Dual-transmitting and dual-receiving terminal: The terminal supports uplink transmission and downlink reception on two card networks at the same time.

In some embodiments, for dual-transmitting, dual-receiving, multi-card terminals, each card can use its own independent hardware/capabilities to Supports parallel transmission. In addition, when some hardware/capabilities of the terminal (such as a mobile phone) can be dynamically switched between the two cards, the terminal can indicate to the network side that some of its capabilities are limited or that its capabilities are no longer restricted, or it can Request to activate some functions, or request to release some resources. For example, when card A is in the connected state and card B is in the non-connected state, the terminal's capabilities are occupied by card A. If card B is going to establish or restore an RRC connection, it needs to cut part of the capabilities of card A to card B. At this time, the terminal needs to indicate a temporary limited capability state to network A. Otherwise, network A will use the UE capabilities previously reported by the terminal. Scheduling the terminal will cause the terminal to lose data on network A or cause a waste of network A resources.

In some embodiments, it can be applied to a dual connectivity (Dual Connectivity, DC) scenario. In this scenario, the terminal is provided with the resources of two network nodes. One of the network nodes is called the master node (Master node, MN), and the other node Called secondary node (Secondary node, SN). At each network node, carrier aggregation technology (Carrier Aggregation, CA) can also be used, that is, the terminal is configured with a series of service cells controlled by the node, and these service cells form a cell group. The cell group controlled by the MN is the Master Cell Group (MCG), and the cell group controlled by the SN is the Secondary Cell Group (SCG). Each cell group contains a special cell (Special Cell, SpCell) and a series of secondary cells (Secondary Cell, SCell). In MCG, the special cell is called Primary Cell (PCell), and in SCG, the special cell is called Primary Secondary Cell (PSCell).

The following is a detailed description of a secondary cell group information sending method, receiving method, terminal, equipment and medium provided by embodiments of the present application through some embodiments and application scenarios with reference to the accompanying drawings.

Please refer to Figure 2. Figure 2 is a flow chart of a method for sending secondary cell group information provided by an embodiment of the present application. As shown in Figure 2, it includes the following steps:

Step 201: The terminal sends a first message according to the first method, where the first message is used to indicate or update the SCG deactivation preference information of the terminal;

Wherein, the first method includes at least one of the following:

When sending the first message, ignore the prohibit timer;

When sending the first message, the prohibition timer is not started;

After sending the first message, perform a first operation;

When sending the first message, preference information instructing the terminal to perform at least one of RLM, BFD and RRM measurements;

The first operation includes at least one of the following:

Control the operating status of the TAT related to the SCG;

In the application scenario of a multi-card terminal, the above terminal corresponds to one card of the multi-card terminal, that is, the above-mentioned SCG deactivation bias The good information is the SCG deactivation preference information of the card corresponding to the above terminal. For example: the above-mentioned multi-card terminal includes card A and card B. Step 201 may be to send the SCG deactivation preference information of card A or card B. It should be noted that the embodiments of the present application are not limited to multi-card terminals. For example, the above step 201 can also be performed for a single-card terminal.

The above prohibition timer can be an SCG deactivation preference prohibit timer (SCG deactivation preference prohibit timer) or an SCG state preference prohibit timer (SCG state preference prohibit timer).

The above-mentioned SCG deactivation preference information may be preference information determined based on the current capabilities, services, resources, etc. of the above-mentioned terminal.

When sending the first message, the prohibition timer may be ignored. If the prohibition timer is running when the terminal sends the first message, the terminal may still send the first message.

The above-mentioned not starting the prohibition timer when sending the first message may mean that when the above-mentioned terminal sends the above-mentioned first message, the above-mentioned prohibition timer is not started.

The sending of the first message when the prohibition timer is not in the running state may be, in the case where the set duration of the prohibition timer does not exceed the first preset value, during the period when the prohibition timer is not in the running state. The first message may be sent without being sent while the inhibit timer is running. The above prohibition timer is not in running state including: not started or timed out.

The above-mentioned performing the first operation after sending the first message may be: performing the first operation when the first message is sent.

The above-mentioned SCG-related TAT may be the uplink synchronization timer of the SCG, and the above-mentioned control of the running status of the SCG-related TAT may be to stop or continue to run the TAT.

The above control of the random access operation of at least one serving cell of the SCG when the SCG activation command is received may be: when the SCG activation command is received, random access is initiated in at least one serving cell of the SCG.

When sending the first message, the preference information instructing the terminal to perform at least one of the RLM, BFD and RRM measurements may be that the first message carries the preference of at least one of the RLM, BFD and RRM measurements. Information, or preference information for at least one of the above-mentioned RLM, BFD and RRM measurements, is sent together with the above-mentioned first message through other messages.

In the embodiment of this application, through the above steps, the terminal can report the SCG deactivation preference information in a timely manner to avoid affecting the communication performance of the terminal and achieve the effect of improving the communication performance of the terminal.

In addition, since after sending the first message, the first operation is performed to control the operating status of the TAT related to the SCG and/or to control the random access operation of at least one serving cell of the SCG, so that the network side can clearly understand the operation status of the TAT related to the SCG. Describes whether the SCG is successfully activated or can start to be scheduled, so that when it is determined that the SCG is successfully activated or can start to be scheduled, the network side communicates with the terminal, thereby improving the communication performance of the terminal, for example: when executing at least one service of the SCG In the case of random access operation of the cell, it is determined that the SCG is successfully activated or scheduling can be started. For example, when TAT is stopped or not running, it is determined that the SCG is successfully activated or scheduling can be started.

When sending the first message, the terminal is instructed to perform biasing of at least one of RLM, BFD and RRM measurements. Good information to avoid performing measurements when the terminal cannot perform RLM, BFD, and RRM measurements during SCG deactivation, resulting in unreliable measurement results or affecting the performance of other cards, thereby improving the communication performance of the terminal.

As an optional implementation manner, the terminal sends the first message according to the first method, including:

When at least one of the following conditions is met, the terminal sends the first message according to the first method:

The first message is sent for a first purpose, and the first purpose is related to multi-card operation;

First indication information sent by the network side is received, where the first indication information is used to indicate that the terminal is allowed or required to send the first message in the first manner.

The above-mentioned multi-card operation may include: at least part of the capabilities of the above-mentioned SCG being occupied by other cards, and/or at least part of the capabilities of the above-mentioned SCG being not occupied by other cards. For example: at least part of the capabilities of card A's SCG are occupied by card B, and at least part of the capabilities of card A's SCG are not occupied by other cards. Sometimes, in order to simplify the explanation, the first purpose can also be simply expressed as for MUSIM purpose.

For example: when the terminal indicates to the network side that its SCG capability is available for the above-mentioned first purpose, it can ignore the prohibition timer, or when the terminal requests the network side to deactivate SCG for the above-mentioned first purpose, the above-mentioned The prohibition timer, or when the SCG deactivation request is due to multi-card operation, the set time of the prohibition timer does not exceed the first preset value, that is, only part of the value can be configured.

If the terminal sends the first message to the network side for other purposes (such as power saving) and the prohibition timer is running, the terminal waits for the prohibition timer to expire before sending the first message.

The first purpose can also be subdivided into performing different tasks on other cards, such as measurement, voice, data, signaling, etc. Then in some implementations, if the terminal sends the first message for the first purpose, if the first purpose If the first purpose is related to the preset services of other cards, the terminal can send it in the first way. If the first destination is not related to the preset services of other cards, the terminal will not send it in the first way, that is, the terminal should send it in the first way when the prohibition timer is not running. sent when.

In this implementation, it is possible to send the above-mentioned first instruction information according to the above-mentioned first manner for the first purpose and/or when the first instruction information is received.

In some implementations, the terminal may immediately send the above-mentioned first message to the network side when the SCG capability is available.

In some embodiments, the terminal may send indication information to the network side device. The indication information may indicate that the SCG capability is available. For example, the field SCG capability (SCG capability) = {restriction, no restriction}. The indication information does not have any restrictions on the prohibition timer. , where restriction means restriction and no restriction means no restriction.

As an optional implementation, the SCG deactivation preference information includes at least one of the following:

The SCG is expected to be deactivated or the SCG is not expected to be deactivated;

No stated SCG deactivation preference;

Desiring the SCG to be activated;

The SCG capabilities are no longer limited or the SCG capabilities are limited.

Wherein, the above-mentioned not expecting the SCG to be deactivated may include no longer expecting the SCG to be deactivated.

SCG deactivation preferences not mentioned above may be through SCG deactivation preference information. (scg-DeactivationPreference) represents preferred, not preferred, no Preference, etc. Among them, not preferred and no Preference can be understood as SCG can be activated or deactivated by the network side, or it can be that the terminal previously instructed to prefer SCG for deactivation, but at this time it indicates that it no longer prefers SCG for deactivation.

For example, in one embodiment, Step 1: The terminal sends an SCG deactivation request and starts the prohibition timer. Step 2: If the terminal wants to indicate to the network side that the SCG capability is available for the above-mentioned first purpose (for example: MUSIM purpose), And the terminal is configured to allow sending this auxiliary information, regardless of whether the SCG deactivation preference prohibition timer (scg-DeactivationPreferenceProhibitTimer) is running, the terminal sends the SCG deactivation preference (scg-DeactivationPreference) to the network side, where the value is set to no preference. (noPreference).

The above-mentioned SCG capability is no longer limited may mean that the SCG can be activated or deactivated by the network side. The above-mentioned SCG capability limitation may mean that part or all of the SCG capability is restricted. In the case where part of the capability is restricted, the SCG may be Network-side activation can also be deactivated, or some functions can be deactivated, or some resources can be released.

In this embodiment, the above preference information can enable the network side device to activate or deactivate the terminal's SCG based on the terminal's preference to optimize network side control. For example, the network side device configures measurements during SCG deactivation for the terminal, or during SCG downlink Activate SCG when data arrives, etc.

Optionally, in the case where the first message indicates that the terminal expects the SCG to be deactivated, the prohibition timer is not started.

In this embodiment, when the SCG is expected to be deactivated, the prohibition timer is not started, so that the terminal can update the SCG deactivation preference information in a timely manner if the terminal's SCG is available later, such as a timely indication that it is no longer expected. SCG is deactivated.

For example: in one embodiment, step 1: the terminal requests SCG deactivation for the above first purpose. After the terminal sends the SCG deactivation request, the prohibition timer is not started; step 2: the terminal ends the service of another card. , when the SCG capability of this card is available, the terminal sends scg-DeactivationPreference to the network side, and the value is set to not preferred.

Optionally, the terminal implements at least one of the following methods to ensure that the set duration of the prohibition timer does not exceed the first preset value:

When the duration configuration information of the prohibition timer is received and the duration configuration information exceeds the first preset value, the terminal defaults to the prohibition timer when sending the first message. The duration is the first preset value;

Receive second indication information, the second indication information is specifically used to indicate the duration of the prohibition timer used when the terminal sends the first message to the network side for a first purpose, the first purpose is related to multi-card Operation-related, the duration does not exceed the first preset value;

After sending the first message, reconfiguration information of the prohibition timer duration is received, and the reconfiguration information reconfigures the set duration of the timer to a value that does not exceed the first preset value.

When the terminal sends the first message, the terminal may default the duration of the prohibition timer to the first preset value. When sending the first message, the terminal may proactively determine the duration of the prohibition timer to be the first preset value. The default value is used instead of the value configured in the above duration configuration information to achieve timely sending of the first message.

The duration of the prohibition timer indicated by the second indication information does not exceed the first preset value, so that the terminal can send the first message in time through the second indication information.

The above-mentioned reconfiguration information may be to reconfigure the duration of the above-mentioned prohibition timer, so as to reconfigure the set duration of the timer to a value that does not exceed the first preset value, so as to achieve timely sending of the first message.

For example: in one embodiment, the above-mentioned second indication information may be scg-DeactivationPreferenceProhibitTimerForMuSIM-r18, or the reconfiguration information may be reconfiguration SCG-DeactivationPreferenceConfig-r17, where:

SCG-DeactivationPreferenceConfig-r17::=SEQUENCE{

scg-DeactivationPreferenceProhibitTimer-r17ENUMERATED{s0,s1,s2,s4,s8,s10,s15,s30,s60,s120,s180,s240,s300,s600,s900,s1800}

scg-DeactivationPreferenceProhibitTimerForMuSIM-r18ENUMERATED{s0,s1,s2,s4,s8,s10}}

In this embodiment, the SCG deactivation preference configuration (scg-DeactivationPreferenceConfig) may include:

The configuration of the terminal is used to indicate the terminal's preference for SCG deactivation (Configuration of the UE to indicate its preference for SCG deactivation).

The SCG deactivation preference prohibition timer can be configured as follows:

Inhibition timer is the value in seconds used by the terminal to indicate the SCG deactivation preference. The value s0 means the inhibit timer is set to 0 seconds, the value s1 means the inhibit timer is set to 1 second, and so on. If the terminal requests SCG deactivation for MUSIM purposes, values that are too large should be avoided, such as values not exceeding 10 seconds. (Prohibit timer for UE indication of its preference for SCG deactivation.Value in seconds.Value s0 means prohibit timer is set to 0 seconds,value s1 means prohibit timer is set to 1 second and so on.If SCG deactivation is requested by the UE for MUSIM purpose,the value longer than 10s shall be avoided.)

As an optional implementation manner, controlling the running status of the SCG-related time synchronization timer TAT includes:

Generally speaking, if the TAT is running, the uplink can be considered to be in synchronization. If the TAT has not started or has timed out, the uplink is considered to be out of sync. When the terminal receives the SCG deactivation command, the terminal keeps the TAT of the SCG in the running state. In this way, if the terminal is out of synchronization in the uplink (TAT is not running) when the SCG is activated, the terminal needs to perform a random access process to obtain uplink synchronization. If the uplink is synchronous (TAT is running), then the terminal does not need to perform random access and can directly start monitoring the physical downlink control channel (Physical Downlink Control Channel, PDCCH) to receive the scheduling of the secondary base station. This method is also called the SCG activation method based on omitting the random access channel (Random Access Channel, RACH) (RACH-less)

In the case where an SCG deactivation command or third indication information is received, the TAT is stopped. The third indication information is used to instruct the terminal to stop the TAT.

In this embodiment, TAT is stopped due to receiving the SCG deactivation command or the third instruction information. This prevents the terminal from performing RACH-less activation when the SCG is activated. That is, when the terminal receives the SCG activation command due to TAT timeout, the terminal must send a random access on the PSCell. In this way, in the case of multi-card operation, after activating SCG, the secondary base station receives the uplink signal (random access) actively sent by the terminal on PSCell, and can determine that the terminal's SCG is available (because if the SCG capability is occupied by other cards, the terminal It is difficult to send random access on this card at this time), so that the status synchronization between the secondary base station and the terminal is achieved.

For example: In one embodiment, step 1: the terminal requests the network side to deactivate the SCG; step 2: the terminal receives the SCG deactivation command, if the SCG deactivation command is used to respond to the terminal's SCG based on the first purpose above. Deactivation request, the terminal performs SCG deactivation and stops SCG TAT.

As an optional implementation manner, when receiving an SCG activation command, controlling the random access operation of at least one serving cell of the SCG includes:

Upon receiving the SCG activation command, the terminal initiates random access of at least one serving cell of the SCG; or,

After receiving the SCG activation command and not receiving the fourth indication information, the terminal determines that the configuration is incorrect. The fourth indication information is used to trigger the terminal to perform random access on at least one serving cell of the SCG. .

The above execution of random access may be to initiate a physical random access channel (Physical Random Access Channel, PRACH).

In this embodiment, since the terminal initiates random access to at least one serving cell of the SCG after receiving the SCG activation command, the network side can determine whether at least one service of the SCG is executed when the SCG is activated. Random access of the cell is used to determine whether the terminal's SCG is actually available. That is, if random access of at least one serving cell of the SCG is performed, it is determined that the SCG is actually available, otherwise it is determined to be unavailable. In this way, random access of at least one serving cell of the SCG can be used to indicate that the SCG of the terminal is available, so that the network side device can communicate with the terminal at the SCG to improve the communication performance of the terminal.

For example: In one embodiment, in the Radio Resource Control (RRC) reconfiguration process, the terminal first performs reconfiguration, and then sends a reconfiguration completion message. When it is determined that PSCell RACH needs to be performed, the terminal initiates PSCell RACH. RACH. In this way, the network side device can determine whether the terminal's SCG is actually available by whether RACH is executed when the SCG is activated.

In this embodiment, when the terminal receives the SCG activation command, the terminal has previously indicated to the network side that SCG is unavailable, or indicated that the previous request to the network side for SCG deactivation is for the above-mentioned first purpose. Wherein, "before" here may be a predefined time range before receiving the SCG activation command.

Among them, the absence of SCG state (scg-state) indirectly indicates that SCG is to be activated. In this case, it is also understood that the SCG activation command is carried.

As an optional implementation, the preference information for the terminal to perform at least one of RLM, BFD and RRM measurements includes at least one of the following:

Request the network side to configure or not configure RLM during SCG deactivation;

Request the network side to configure or not configure BFD during SCG deactivation;

Request the network side to configure or not configure RRM measurement during SCG deactivation.

Among them, requesting the network side to configure RLM, BFD and RRM measurements allows high-capacity terminals to perform necessary measurements to ensure that SCG can be activated quickly and stably in the future. Requesting the network side not to configure RLM, BFD and RRM measurements allows low-capacity terminals to perform the necessary measurements when they cannot. Indicates to the network side when measurements are being performed to avoid having to configure these measurements.

For example: in one embodiment, step 1: the terminal requests the network side to deactivate the SCG, indicating that the reason for the request is the first purpose mentioned above, or requesting the network side not to configure at least one of RLM, BFD and RRM during SCG deactivation; Step 2: The terminal receives the SCG deactivation command and instruction information, and determines that at least one of RLM, BFD, and RRM will not be executed during SCG deactivation. The instruction information is used to instruct the terminal to delete the saved During SCG deactivation, the configuration information of at least one of RLM, BFD and RRM is executed.
