[0035] Figure 1A block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can also be referred to as a terminal device or a user terminal (User Equipment, UE). The terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc. Terminal-side devices.

Among them, the base station can be referred to as Node B, evolved Node B, access point, base transceiver station (Base Transceiver Station, BTS), radio base station, radio transceiver, basic service set (Basic Service Set, BSS), extended service set (Extended Service Set, ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, transmitting receiving point (Transmitting Receiving Point, TRP) or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0036] For ease of understanding, some content related to the embodiments of the present invention is described below:

[0037] In the current mobile communication system, two radio access nodes / base stations can be deployed for a terminal to provide service transmission for the terminal simultaneously, namely the dual-connection mode. There are two network nodes in the dual-connection mode. One network node is called the master node (MN), and the other is called the secondary node (SN). In each network node, carrier aggregation technology (CA) can also be used, that is, a series of serving cells controlled by this node are configured for the UE, and this series of serving cells is also called a cell group. The cell group controlled by the master node MN is called the master cell group (MCG), and the cell group controlled by the secondary node SN is called the secondary cell group (SCG). Each cell group contains a special cell (SpCell) and a series of secondary cells (SCells). The special cell in the MCG is called the primary cell (PCell), and the special cell in the SCG is called the primary secondary cell (PSCell).

[0038] Currently, during the SCG state control process, there is a fuzzy period for the SCG state. That is, when the network side determines that the UE has no uplink data to send and the network side also has no downlink data to send, the MN or SN initiates the SCG deactivation, and the MN sends a deactivation command to the UE. Before the UE receives the SCG deactivation command, it is possible that the UE has uplink data again on the SCG. At this time, the UE will send a BSR or initiate a random access on the SCG. Then the SN will think that the UE wants to activate the SCG and set the UE to the active state. On the SN side, the SN thinks that the SCG has entered the active state. However, at this time, the UE receives the SCG deactivation command from the MN, and on the UE side, the SCG enters the deactivated state. The SN notifies the MN of the activated state of the SCG, and the MN thinks that the UE is in the active state of the SCG. As a result, the UE and the network side have opposite understandings of the SCG state, thus there is a problem of SCG state ambiguity.

[0039] The following will combine the accompanying drawings and elaborate on the secondary cell group state control method provided by the embodiments of the present application through some embodiments and their application scenarios.

[0040] See Figure 2 , Figure 2 is one of the flowcharts of a secondary cell group state control method provided by the embodiments of the present application. As Figure 2 shown, the secondary cell group state control method includes the following steps:

[0041] Step 201: The first network element sends and / or receives target information, where the target information is used to control the secondary cell group (SCG) status of the terminal.

[0042] Wherein, the first network element may be a MN and / or a SN.

[0043] In the embodiments of the present application, the first network element sends and / or receives target information, where the target information is used to control the SCG status of the terminal. In this way, by controlling the SCG status through the target information, the resources consumed by the network side can be reduced, and the power consumption of the terminal can also be reduced.

[0044] Optionally, the receiving of the target information includes:

[0045] Receiving first indication information sent by a second network element, where the first indication information is used to indicate at least one of the following:

[0046] The first authorization information for the first network element to directly activate the SCG;

[0047] The second authorization information for the first network element to directly deactivate the SCG.

[0048] Wherein, the target information may include the first indication information.

[0049] Wherein, the first network element may be a MN and the second network element may be a SN; or the first network element may be a SN and the second network element may be a MN.

[0050] In one implementation, when the first indication information is used to indicate the first authorization information for the first network element to directly activate the SCG, it may be indicated that the first network element determines whether to allow direct activation of the SCG according to the trigger condition for activating the SCG. For example:

[0051] If the activation of the SCG is triggered by the terminal, the first network element is allowed to directly activate the SCG;

[0052] If the activation of the SCG is triggered by the first network element, the first network element is not allowed to directly activate the SCG.

[0053] For example, the MN (second network element) indicates to the SN (first network element) that if the terminal triggers the SCG activation process and the SCG activation reason is MCG recovery, the first network element is allowed to directly activate the SCG.

[0054] Exemplarily, the first network element is the MN, the second network element is the SN, and when downlink (DL) data arrives at the MN and the MN is ready to use the SCG to transmit the DL data, it can be considered that the MN triggers the activation of the SCG; when the terminal sends an SCG activation request, it can be considered that the terminal triggers the activation of the SCG. When the terminal initiates a random access or a scheduling request on the SCG / PSCell, it can also be considered that the terminal has sent an SCG activation request.

[0055] In one implementation, when the first indication information is used to indicate the second authorization information for the first network element to directly deactivate the SCG, it can be indicated that the first network element determines whether to allow direct deactivation of the SCG according to the trigger condition for deactivating the SCG. Exemplarily:

[0056] If the deactivation of the SCG is triggered by the terminal, the first network element is allowed to directly deactivate the SCG;

[0057] If the deactivation of the SCG is triggered by the first network element, the first network element is not allowed to directly deactivate the SCG.

[0058] Exemplarily, the first network element is the MN, the second network element is the SN, and when the terminal requests to deactivate the SCG from the MN due to overheating or low battery, if the MN obtains the second authorization at this time, it can first deactivate the SCG and then notify the SN; if the deactivation of the SCG is triggered by the MN, the MN is not allowed to directly deactivate the SCG.

[0059] Exemplarily, when the terminal sends an SCG deactivation request, it can be considered that the terminal triggers the deactivation of the SCG. For example, the terminal sends UE assistance information, which indicates SCG deactivation indication / request information.

[0060] It should be noted that currently, when downlink data arrives at the MN and the MN wants to activate the SCG to use the resources of the SCG, the MN needs to send an SCG activation request to the SN, and then send an SCG activation command to the UE after receiving the acceptance response of the activation request from the SN, resulting in relatively low effectiveness of SCG state control. In this embodiment, in some cases, the SN can pre - send authorization to activate the SCG to the MN, that is, allow the MN to send an SCG activation to the UE without the confirmation of the SN. Correspondingly, when the conditions do not allow, the SN can also cancel the authorization, thereby improving the effectiveness of SCG state control.

[0061] In this embodiment, the first network element receives the first indication information sent by the second network element, and the first indication information is used to indicate at least one of the following: the first authorization information for the first network element to directly activate the SCG; the second authorization information for the first network element to directly deactivate the SCG. In this way, the first network element can directly activate or deactivate the SCG based on the first indication information, can achieve rapid activation or deactivation of the SCG, can improve the effectiveness of SCG state control, and can solve the problem of low effectiveness of current SCG state control; and can avoid frequent signaling interactions on the Xn interface.

[0062] Optionally, the method further includes:

[0063] The first network element sends a response to the first indication information to the second network element; and / or,

[0064] The first network element sends a first request to the second network element, and the first request is used to request the second network element to send the first indication information.

[0065] In one embodiment, before the first network element receives the first indication information sent by the second network element, the first network element sends a request to the second network element, requesting the second network element to send the target information; after the first network element receives the first indication information sent by the second network element, the first network element sends a response to the first indication information to the second network element.

[0066] For example, the MN applies for the first authorization from the SN, the SN configures or grants the first authorization to the MN, and the MN sends a confirmation of the first authorization to the SN.

[0067] Optionally, the first authorization information is used to indicate at least one of the following:

[0068] The first authorization, which is used to indicate that the first network element is allowed to directly activate the SCG;

[0069] Activating the first authorization;

[0070] Deactivating or canceling the first authorization;

[0071] Not authorizing or not allowing the first network element to directly activate the SCG;

[0072] The valid time of the first authorization;

[0073] The associated SCG configuration of the first authorization.

[0074] Among them, within the valid time, the first authorization can be considered valid; if it is outside the valid time, the first authorization can be considered canceled.

[0075] In one implementation, when the second network element authorizes the first network element to directly activate the SCG, the second network element sends to the first network element the SCG information that allows the first network element to send to the terminal, and the SCG information includes the associated SCG configuration of the first authorization.

[0076] It can be understood that the associated SCG configuration information of the first authorization is the SCG configuration information sent to the terminal when the SCG is directly activated by the first network element during the validity period of the first authorization. If the first authorization is not valid (for example, after the expiration of the validity period of the first authorization), the first network element may delete the saved associated SCG configuration.

[0077] Optionally, the second authorization information is used to indicate at least one of the following:

[0078] The second authorization, which is used to indicate that the first network element is allowed to directly deactivate the SCG;

[0079] Activate the second authorization;

[0080] Deactivate or cancel the second authorization;

[0081] Do not authorize or do not allow the first network element to directly deactivate the SCG;

[0082] The valid time of the second authorization;

[0083] The associated SCG configuration of the second authorization.

[0084] In one implementation, when the second network element authorizes the first network element to directly deactivate the SCG, the second network element sends to the first network element the SCG information that allows the first network element to send to the terminal, and the SCG information includes the associated SCG configuration of the second authorization.

[0085] It can be understood that the associated SCG configuration information of the second authorization is the SCG configuration information sent to the terminal when the SCG is directly deactivated by the first network element during the validity period of the second authorization. If the second authorization is not valid (for example, after the expiration of the validity period of the second authorization), the first network element may delete the saved associated SCG configuration.

[0086] Optionally, the associated SCG configuration of the first authorization includes at least one of the following:

[0087] After the SCG is activated, the target state of at least one serving cell in the SCG;

[0088] After the SCG is activated, the number or list of serving cells immediately activated in the SCG;

[0089] After the SCG is activated, the uplink resources available for the SCG;

[0090] After the SCG is activated, the downlink resources available for the SCG.

[0091] For example, after the SCG is activated, the UE can have available random access resources, PUCCH resources, uplink resources such as configured grants, etc. Or have available reference signal resources for measurement.

[0092] Optionally, the associated SCG configuration of the second authorization is used to indicate at least one of the following:

[0093] After the SCG is deactivated, the terminal clears at least part of the downlink resources of the SCG;

[0094] After the SCG is deactivated, the terminal clears at least part of the uplink resources of the SCG;

[0095] After the SCG is deactivated, the terminal does not perform a first operation on the SCG, and the first operation includes at least one of the following:

[0096] Beam management, Beam Failure Detection (BFD), Beam Failure Recovery (BFR), Channel State Information (CSI) measurement, CSI measurement reporting, random access, Radio Link Monitoring (RLM) measurement, Radio Resource Management (RRM) measurement.

[0097] For example, after the SCG is deactivated, the random access resources of the SCG are deleted through the associated SCG configuration information, thereby saving network uplink resources. It can be understood that in some cases, the associated SCG configuration of the second authorization can also be generated by the first network element.

[0098] Optionally, the method further includes:

[0099] When the SCG of the terminal is directly activated or directly deactivated by the first network element, the first network element indicates the state of the SCG to the second network element.

[0100] The following is an example through a specific embodiment. In this embodiment, the first network element is the MN, the second network element is the SN, and the secondary cell group state control method includes the following process:

[0101] The SN sends first indication information to the MN;

[0102] The MN sends a response to the first indication information to the SN.

[0103] Among them, the first indication information can be sent at any time, such as when SN addition (increase), SN change, SN reconfiguration, the SCG is in the deactivated state, or the SCG is in the activated state.

[0104] In one implementation, before the MN receives the first indication information sent by the SN, the MN sends a request to the SN, requesting the SN to send the target information; after the MN receives the first indication information sent by the SN, the MN sends a response to the first indication information to the SN.

[0105] Currently, when downlink data arrives at the MN and the MN wants to activate the SCG to use the SCG resources, the MN sends an SCG activation request to the SN, and then sends an SCG activation command to the UE after receiving the acceptance response of the SN to the SCG activation request. In this embodiment, in order to achieve fast activation of the SCG, the SN can send an authorization to activate the SCG to the MN in some cases, that is, allowing the MN to directly activate the SCG of the UE without the confirmation or participation of the SN. Accordingly, when the conditions do not allow, the SN can also cancel the authorization. Thereby, it can accelerate the activation and deactivation of the SCG and improve the effectiveness of controlling the SCG state.

[0106] Optionally, the receiving the target information includes receiving the target information sent by a second network element, and the target information includes at least one of the following:

[0107] SCG status indication information;

[0108] Indication information for instructing the first network element to cancel sending an SCG deactivation command to the terminal;

[0109] Indication information for instructing the first network element to send an SCG activation command to the terminal.

[0110] The following is illustrated by a specific embodiment. In this embodiment, the first network element is the MN, the second network element is the SN, and the secondary cell group status control method includes the following processes:

[0111] (1): The SN initiates an SCG deactivation request;

[0112] (2): The MN sends an acceptance response to the SCG deactivation request to the SN;

[0113] (3): Before the UE receives the SCG deactivation command sent by the MN, if uplink data arrives and there is no PUSCH resource, the UE initiates a RACH or SR to the SCG;

[0114] (4): After receiving the RACH or SR of the UE, the SN determines the status of the SCG based on the information therein;

[0115] (5): If the SN determines that the SCG is still in the active state, the SN sends to the MN indication information for indicating the status of the SCG (indicating that the SCG of the UE is currently in the active state) and / or a request to cancel the transmission of the SCG deactivation command;

[0116] (6): After receiving the indication information sent by the SN, the MN cancels the transmission of the SCG deactivation command, or sends a SCG activation command to the UE.

[0117] Thus, after receiving the SCG activation notification, if the SCG deactivation command has not been sent, the MN can cancel the sending; if the SCG deactivation command has been sent, the MN can send the SCG activation command to the UE again, which can solve the problem of ambiguous SCG status.

[0118] In this embodiment, by receiving the target information sent by the second network element, it is possible to avoid inconsistent understandings of the SCG status between the network side and the terminal, and further avoid subsequent incorrect configurations caused by inconsistent understandings of the SCG status between the network side and the terminal, avoid communication anomalies, and thus improve the stability of SCG activation and deactivation control.

[0119] Optionally, the target information includes at least one of the following:

[0120] SCG deactivation request;

[0121] SCG deactivation indication;

[0122] SCG activation request;

[0123] SCG activation indication;

[0124] SCG status indication information.

[0125] Among them, the SCG deactivation indication includes a response to the SCG deactivation request initiated by the second network element, or can also be that the first network element instructs the second network element to deactivate the SCG. The SCG activation indication includes a response to the SCG activation request initiated by the second network element, or can also be that the first network element instructs the second network element to activate the SCG. The SCG status indication information is used to indicate the current status of the SCG.

[0126] Optionally, after the first network element sends the target information, and / or receives the target information, the method further includes:

[0127] The first network element starts a timer.

[0128] Optionally, after the first network element starts the timer, the method further includes:

[0129] The first network element does not perform at least one of the following during the operation of the timer:

[0130] Transmit part or all of the target information;

[0131] Activate the SCG;

[0132] Deactivate the SCG;

[0133] Respond to the SCG activation request of the terminal;

[0134] Respond to the SCG deactivation request of the terminal.

[0135] In one implementation, not activating the SCG may include at least one of the following:

[0136] Do not schedule the SCG;

[0137] Do not respond to the random access or SR of the UE;

[0138] Do not respond to the SCG activation request of the UE.

[0139] In this implementation, by defining the behaviors that the first network element does not perform during the operation of the timer, the problem of SCG state ambiguity can be solved, thereby improving the stability of SCG activation and deactivation control.

[0140] Optionally, in the case where the timer expires or does not run, the behaviors of the first network element include at least one of the following:

[0141] Allow the transmission of the target information;

[0142] Allow the deactivation of the SCG;

[0143] Allow the activation of the SCG;

[0144] Allow responding to the SCG activation request of the terminal;

[0145] Allow responding to the SCG deactivation request of the terminal.

[0146] In this implementation, the timer can be used to keep the SCG state synchronized between the first network element and the second network element. After the first network element sends and / or receives the target information, the first network element starts the timer, which can enable the network side to keep the SCG state synchronized.

[0147] Optionally, the method further includes: when at least one of the following conditions is satisfied, the first network element stops the timer:

[0148] Receive the response to the target information sent by the second network element;

[0149] A SCG release request or indication is received.

[0150] In some specific scenarios, the conditions for the first network element to stop the timer further include at least one of the following:

[0151] A status indication of the SCG is received;

[0152] An SCG activation indication is received;

[0153] An SCG deactivation indication is received;

[0154] An SCG activation request is received;

[0155] An SCG deactivation request is received;

[0156] In one implementation, when the target information includes an SCG activation request, an SCG activation indication, or SCG status indication information, if the first network element receives an SCG release request or indication, the first network element stops the timer.

[0157] For example, after the first network element sends an SCG deactivation request to the second network element, the first network element starts the timer. During the running of the timer, the first network element does not send an SCG deactivation request again. During the running of the timer, if the first network element receives an indication from the second network element that the SCG has been successfully deactivated, the first network element stops the timer, or if the first network element does not stop the timer at this time, during the running of the timer, the first network element does not send an SCG activation request.

[0158] For another example, after the first network element sends an SCG deactivation indication to the second network element (the SCG deactivation indication can also be a response to an SCG deactivation request sent by the second network element), the timer is started. During the running of the timer, the first network element does not schedule the UE. During the running of the timer, if the first network element receives an indication from the second network element that the SCG has been successfully deactivated, the first network element stops the timer. If the timer times out, the first network element resumes scheduling the UE or responds to the information sent by the UE on the SCG.

[0159] In one implementation, the first network element is the SN, the second network element is the MN, and the SN starts the timer after sending one of the following information to the MN:

[0160] An SCG deactivation request;

[0161] An SCG deactivation indication;

[0162] An SCG activation request;

[0163] An SCG activation indication;

[0164] SCG status indication information;

[0165] Among them, the SCG deactivation indication may include a response to the SCG deactivation request initiated by the MN, or the SN may indicate to the MN to deactivate the SCG. The SCG activation indication includes a response to the SCG activation request initiated by the MN, or the SN may indicate to the MN to activate the SCG.

[0166] In addition, during the operation of the timer, the behavior of the SN includes at least one of the following:

[0167] Not sending an SCG deactivation request to the MN;

[0168] Not sending an SCG activation request to the MN;

[0169] Not activating the SCG;

[0170] Not sending the SCG status indication information to the MN.

[0171] Among them, during the operation of the timer, the SN does not send an SCG deactivation request to the MN, so as to be able to prohibit the SN from frequently requesting within a short period of time; during the operation of the timer, the SN does not send an SCG activation request to the MN, so as to be able to prohibit the SN from frequently changing the SCG state within a short period of time; during the operation of the timer, the SN does not activate the SCG, so as to avoid potential state inconsistency problems caused by the SN activating the SCG by itself.

[0172] For example, after the SN sends an SCG deactivation request to the MN, the SN starts the timer. During the operation of the timer, the SN does not schedule the SCG. If the SN receives an indication that the SCG has been successfully deactivated sent by the MN during the operation of the timer, the SN stops the timer. If the SN receives a rejection response to the SCG deactivation request sent by the MN during the operation of the timer, the SN stops the timer, and the SN can resume scheduling the SCG.

[0173] In one implementation, the first network element is the MN, the second network element is the SN, and the MN starts the timer after performing one of the following:

[0174] Sending an SCG deactivation request to the SN;

[0175] Sending an SCG deactivation indication to the SN;

[0176] Sending an SCG activation request to the SN;

[0177] Sending an SCG activation indication to the SN;

[0178] Receiving the SCG status indication information sent by the SN.

[0179] In addition, during the operation of the timer, the behavior of the MN includes at least one of the following:

[0180] Do not send an SCG activation request to the SN;

[0181] Do not send an SCG deactivation request to the SN;

[0182] Do not activate the SCG;

[0183] Do not respond to the UE's SCG activation request;

[0184] Do not send SCG status indication information to the MN.

[0185] Optionally, the sending of the target information includes:

[0186] If the first network element receives a random access message or a scheduling request sent by the terminal, and the random access message or the scheduling request does not contain second indication information, then the first network element sends third indication information to the terminal;

[0187] Wherein, the second indication information is used to indicate a request to activate the SCG or indicate that the current state of the SCG is the deactivated state, and the third indication information is used to indicate that the terminal ignores the SCG deactivation command received from the second network element.

[0188] In addition, the third indication information can be used to indicate that the terminal ignores the SCG deactivation command received from the second network element within a third preset duration, and the third preset duration can be 500 ms, or 1 s, or 5 s, etc., and this embodiment does not limit this.

[0189] The following is illustrated by a specific embodiment. In this embodiment, the first network element is the SN, the second network element is the MN, and the secondary cell group status control method includes the following processes:

[0190] (1): When the SCG of the UE is in the deactivated state, if uplink data arrives at the SCG, during the process of the UE initiating a RACH or an SR to the SCG or after the UE initiates a random access (RACH) or a scheduling request (SR) to the SCG, the UE indicates to the SCG a request to activate the SCG or indicates that the current state of the SCG is the deactivated state;

[0191] (2): The UE receives indication information from the SN, and this indication information indicates whether the UE should execute the SCG deactivation command received from the MN. If it indicates that the UE executes the SCG deactivation command, the UE deactivates the SCG; if it indicates that the UE ignores the SCG deactivation command, the UE does not deactivate the SCG.

[0192] In this embodiment, if the first network element receives a random access message or a scheduling request sent by a terminal, and the random access message or the scheduling request does not contain second indication information, then the first network element sends third indication information to the terminal, which can solve the problem of SCG state ambiguity, thereby improving the stability of SCG activation and deactivation control.

[0193] Optionally, the receiving of the target information includes:

[0194] The first network element receives an SCG activation request sent by a second network element;

[0195] The method further includes:

[0196] The first network element sends the current state of the SCG to the second network element.

[0197] In one embodiment, the first network element sends the current state of the SCG to the second network element, and the current state of the SCG does not trigger the second network element to send an SCG activation command to the UE.

[0198] In one embodiment, the first network element receives an SCG activation request sent by a terminal, the first network element activates the SCG of the terminal, the first network element receives an SCG activation request sent by a second network element, and the first network element sends the current state of the SCG to the second network element.

[0199] Optionally, the target information is used for at least one of the following:

[0200] Indicate the current state of the SCG to the terminal;

[0201] Indicate the SCG configuration to the terminal;

[0202] Indicate to the terminal that the terminal ignores some or all of the SCG configuration information received from the second network element within a first preset duration.

[0203] Wherein, the first preset duration can be 500 ms, or 1 s, or 5 s, etc., and this embodiment does not limit this.

[0204] In one implementation, a first network element receives an SCG activation request from a second network element, and the first network element sends an approval response to the SCG activation request to the second network element; before the terminal receives an SCG activation command sent by the second network element, the terminal initiates a random access request or a scheduling request to request the first network element to activate the SCG; the first network element receives the SCG activation request from the terminal, determines that the terminal has not received the SCG activation command sent by the second network element before sending the SCG activation request, and indicates the current state of the SCG to the terminal, or indicates the SCG configuration to the terminal, or indicates to the terminal that the terminal ignores some or all of the SCG configuration information received from the second network element within a first preset duration.

[0205] The following uses two specific embodiments for illustration. Among them, the first network element is the SN, and the second network element is the MN.

[0206] Embodiment 1:

[0207] The secondary cell group status control method includes the following process:

[0208] (1): The SCG of the UE is in the deactivated state;

[0209] (2): The UE has uplink data to send and requests the SN to activate the SCG, for example, initiating a RACH or a scheduling request;

[0210] (3): The SCG of the UE is activated;

[0211] (4): The SN receives an SCG activation request sent by the MN. Exemplarily, the SCG activation request may be sent by the MN to the SN after there is downlink data arriving at the MN. The SN receives the SCG activation request sent by the MN before the SN has not notified the MN that the SCG has been activated;

[0212] (5): The SN sends SCG status indication information to the MN, and the SCG status indication information is used to indicate the current state of the SCG. Further, the SCG status indication information does not trigger the MN to send an SCG activation command to the UE.

[0213] Embodiment 2:

[0214] The secondary cell group status control method includes the following process:

[0215] (1): The SCG is in the deactivated state;

[0216] (2): The SN receives an SCG activation request sent by the MN;

[0217] (3): The SN sends a reply to the SCG activation request to the MN. For example, confirming that the SCG can be activated;

[0218] (4): Before the UE receives the SCG activation command sent by the MN, if the UE has uplink data to send on the SCG, the UE requests the SN to activate the SCG, for example, initiating a RACH or a scheduling request.

[0219] (5): After receiving the SCG activation request from the UE, if the SN determines that the UE has not received the SCG activation command sent by the MN before sending this message, the SN sends any one of the following indication messages to the UE:

[0220] SCG status indication information;

[0221] SCG configuration;

[0222] Indicating whether the UE ignores all or part of the SCG status information and / or all or part of the SCG configuration information received from the MN within a period of time. For example, the SN indicates that the UE activates the SCG and reconfigures part of the SCG configuration, and indicates that if the UE receives the SCG synchronization reconfiguration parameters from the MN, the UE may not initiate a random access.

[0223] In this embodiment, the first network element sends the current state of the SCG to the second network element, or the first network element sends the target information, thereby being able to solve the processing problem of the terminal and the second network element simultaneously requesting the first network element to activate the SCG.

[0224] See Figure 3 , Figure 3 is the second flowchart of a secondary cell group status control method provided by an embodiment of the present application. As Figure 3 shown, the secondary cell group status control method includes the following steps:

[0225] Step 301, the terminal receives target information for controlling the status of the secondary cell group SCG.

[0226] In the embodiment of the present application, the terminal receives target information for controlling the status of the secondary cell group SCG. In this way, by controlling the SCG status through the target information, the resources consumed by the network side can be reduced, and the power consumption of the terminal can be reduced.

[0227] Optionally, the terminal receiving the target information for controlling the SCG status includes:

[0228] The terminal receives an SCG deactivation command sent by the first network element at a first moment;

[0229] The method further includes:

[0230] If the terminal receives an SCG activation command before and / or after the first moment within a second preset duration, the terminal ignores the SCG deactivation command.

[0231] The second preset duration may be 500 ms, 1 s, 5 s, etc., which is not limited in this embodiment.

[0232] The following is an example of a specific embodiment, in which the secondary cell group state control method includes the following process:

[0233] (1): SN initiates SCG deactivation request;

[0234] (2): MN sends an acceptance response of the SCG deactivation request to the SN, and sends an SCG deactivation command to the UE;

[0235] (3): Before the UE receives the SCG deactivation command, the UE's SCG is still in the activated state. If uplink data arrives at the SCG, the UE initiates a RACH or SR to the SCG in the absence of PUSCH resources.

[0236] (4): UE receives the SCG activation command from SN;

[0237] (5): If the UE receives an SCG deactivation command from the MN within a preset time range of receiving the SCG activation command, the UE ignores the SCG deactivation command. The preset time range may be determined by a protocol agreement or a network configuration.

[0238] In this implementation, the terminal receives an SCG deactivation command from the second network element within a short period of time after receiving the SCG activation command from the first network element, and ignores the received SCG deactivation command, which can solve the problem of SCG status ambiguity and improve the stability of SCG activation and deactivation control.

[0239] Optionally, the terminal receives target information for controlling the SCG state, including:

[0240] The terminal receives third indication information sent by the first network element, where the third indication information is used to instruct the terminal to ignore the SCG deactivation command received from the second network element.

[0241] Optionally, the terminal receives target information for controlling the SCG state, including:

[0242] The terminal receives a first SCG state control instruction sent by the first network element;

[0243] The terminal receives a second SCG state control instruction sent by a second network element;

[0244] The method further comprises:

[0245] The terminal executes the first SCG state control instruction or the second SCG state control instruction according to a preset priority.

[0246] Among them, the first SCG status control instruction can be used to control the SCG status and can include at least one of the following: SCG deactivation request, SCG deactivation indication, SCG activation request, or SCG activation indication, etc. The second SCG status control instruction can be used to control the SCG status and can include at least one of the following: SCG deactivation request, SCG deactivation indication, SCG activation request, or SCG activation indication, etc.

[0247] The above preset priority can be used to indicate the one with the highest priority among the first network element and the second network element. By way of example, the preset priority can include the priority of the first network element and the priority of the second network element.

[0248] A specific embodiment is given below for illustration. In this embodiment, the first network element is the MN, the second network element is the SN, and the secondary cell group status control method includes the following processes:

[0249] (1): The SCG of the UE is in the deactivated state;

[0250] (2): The UE sends an SCG activation request to the SN and receives an acceptance response from the SN;

[0251] (3): The UE receives an acceptance response to the SCG activation request from the SN; at the same time, the UE receives an SCG deactivation command from the MN;

[0252] (4): The UE gives a high priority to the SCG deactivation command sent by the MN and ignores the SCG activation command sent by the SN.

[0253] In this embodiment, the terminal determines how to control the SCG status based on the defined priority, which can solve the problem of SCG status ambiguity caused when the terminal receives SCG status control instructions sent by both the SN and the MN at the same time.

[0254] It should be noted that, as the embodiment corresponding to the terminal side in the embodiment shown in Figure 2 , for the specific implementation part, reference can be made to the relevant description of the embodiment shown in Figure 2 To avoid repeated description, this embodiment will not be elaborated herein.
