Description

Control method, communication device and storage medium Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a control method, communication equipment, and storage medium. Background Art

[0002] The terminal device has the need to add SCG (Secondary Cell Group) under different business requirements, which can be achieved through CPA (Conditional PSCell Addition). In the existing CPA process, the network device controls the timing of the terminal device to start the CPA candidate cell evaluation (such as issuing C5PA conditional configuration through the network device). After the terminal device adds SCG during the CPA candidate cell evaluation process, the original CPA candidate cell configuration information will be deleted. The selective activation cell group supports a continuous SCG addition process. After the SCG addition is executed, the original selective activation cell group candidate cell configuration information is not deleted.

[0003] During the process of conceiving and implementing this application, the inventors discovered that there are at least the following problems: for terminal devices after the SCG is released by the network device, if the selective activation cell group configuration information is not deleted, the evaluation of candidate cells in the selective activation cell group will still be started, causing the terminal device to generate additional energy consumption due to initiating unnecessary SCG addition processes; and / or, the existing selective activation cell group process is usually triggered by the signal quality of the candidate cell, which easily causes the terminal device to frequently initiate SCG addition or deletion processes, resulting in unnecessary energy consumption of the terminal device.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Technical Solutions

[0063] Implementation Methods of the Application

[0064] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0065] It should be noted that, in this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0066] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the recited features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0067] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0068] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0069] It should be noted that in this article, step codes such as S1 and S2 are used for the purpose of expressing the corresponding content more clearly and concisely, and do not constitute a substantial restriction on the order. When implementing the step, those skilled in the art may execute S2 first and then S1, etc., but these should all be within the scope of protection of this application.

[0070] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0071] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0072] The communication device in this application can be a terminal device (such as a mobile phone) or a network device (such as a base station). The specific reference needs to be clarified based on the context.

[0073] The terminal device may be implemented in various forms. For example, the terminal device described in this application may include intelligent terminal devices such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and other fixed terminal devices such as digital TVs and desktop computers.

[0074] The subsequent description will be made using a mobile terminal as an example. Those skilled in the art will understand that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminal devices.

[0075] Please refer to Figure 1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0076] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0077] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G and 6G, etc.

[0078] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without changing the essence of the invention.

[0079] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0080] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0081] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

[0082] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0083] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0084] Optionally, the touch panel 1071 may overlay the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0085] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0086] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0087] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0088] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing functions such as charging, discharging, and power consumption through the power management system.

The available medium can be a magnetic medium (e.g., a floppy disk, a hard disk, a tape), an optical medium (e.g., a DVD), or a semiconductor medium (e.g., a solid state drive solid state disk, SSD), etc.

[0103] Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0104] First embodiment

[0105] 5 , which is a flow chart of a control method according to a first embodiment, the control method can be applied to a terminal device (such as a mobile phone), and includes the following steps:

[0106] In response to a first condition being met, candidate cells in the selectively activated cell group are not evaluated; or, in response to a second condition being met, candidate cells in the selectively activated cell group are evaluated.

[0107] Optionally, when the terminal satisfies the first condition, the evaluation of candidate cells in the selectively activated cell group is not started. On this basis, when the terminal satisfies the second condition, the evaluation of candidate cells in the selectively activated cell group is started to avoid the terminal being unable to be added to the SCG in time.

[0108] In an embodiment of the present application, for a continuous CPA (Conditional PSCell Addition) scenario, a terminal device releases or adds an SCG (Secondary Cell Group) due to energy saving, overheating, or traffic volume, and a method for controlling whether to evaluate a CPA candidate cell can be provided. It should be noted that this method is also applicable to the evaluation of candidate cells in a selectively activated cell group. During the evaluation of a CPA candidate cell by the terminal device, the candidate cell is measured according to a measurement event associated with the measurement identifier in the execution condition in the candidate cell condition configuration. If the evaluation execution condition is met (that is, the entry condition of the associated measurement event is met), the terminal device executes the conditional reconfiguration process to add the SCG.

[0109] Optionally, satisfying the first condition includes at least one of the following: receiving a deactivation command for the selective activation cell group function, the terminal device is in an energy-saving state, the terminal device is in an overheating state, receiving a secondary cell group release command containing a specific reason value, and the terminal device traffic volume does not reach the first threshold value.

[0110] Optionally, for a terminal device configured with the CPA selective activation of the cell groups function, when the terminal device is in an energy-saving state and / or an overheating state, the evaluation of candidate cells in the selective activation cell group is not started.

[0111] Optionally, if the network device receives an energy saving request and / or an overheating report from the terminal device to release the SCG, the network device may simultaneously issue a command to deactivate the selective activation cell group function when issuing a release SCG command. Optionally, the command to deactivate the selective activation cell group function may be issued by instructing a Media Access Control Control Element (MAC CE).

[0112] Optionally, if the terminal device receives a command to deactivate the selective activation cell group function, it starts a timer. While the timer is running, the selective activation cell group configuration information is kept valid. If the timer times out, the selective activation cell group configuration information is released, that is, the previously configured selective activation cell group configuration is retained until the timer times out.

[0113] Optionally, in order to prevent the network device from reserving CPA resources for the terminal device when the terminal device is in an energy-saving state and / or an overheating state for a long time, the network device starts a timer when sending a command to deactivate the CPA selective activation cell group function. During the timer running, the CPA candidate cell configuration is still valid. When the timer times out, if the terminal device is still in an energy-saving state and / or an overheating state, that is, the terminal device has not sent a cancellation request for energy-saving and / or overheating, the network device and the terminal device can release the CPA resources at the same time.

[0114] Optionally, when the network device decides to start the CPA selective activation cell group function and configures the CPA candidate cell configuration information, in addition to configuring the signal conditions for starting the CPA candidate cell evaluation, it can also configure the uplink traffic conditions at the same time, such as the first threshold value and the second threshold value in this application. The CPA selective activation cell group function is deactivated by default, and the terminal device does not start the CPA candidate cell evaluation.

[0115] Optionally, satisfying the second condition includes at least one of the following: receiving a command to activate the selective activation cell group function, the terminal device is not in an energy-saving state and / or an overheating state, and the terminal device traffic reaches a second threshold value.

[0116] Optionally, if the terminal device is not in the energy-saving state and / or the overheating state, the evaluation of candidate cells in the selectively activated cell group may be initiated.

[0117] Optionally, if the network device receives a request from the terminal device to cancel energy saving and / or overheating, that is, the terminal device is not in an energy saving state and / or an overheating state, the network device issues an activate selective activation cell group function command, causing the terminal device to start evaluating candidate cells in the selective activation cell group. Optionally, the activate selective activation cell group function command may be issued by instructing the medium access control layer control element MAC CE.

[0118] Optionally, when the uplink traffic condition of the terminal device is met, for example, the traffic volume of the terminal device reaches a second threshold value, the terminal device activates the CPA selective activation cell group function and starts the CPA candidate cell evaluation.

[0119] This embodiment uses the above-mentioned scheme, specifically by not evaluating the candidate cells in the selectively activated cell group in response to the first condition being met; or, in response to the second condition being met, evaluating the candidate cells in the selectively activated cell group, thereby reducing unnecessary evaluation of candidate cells in the selectively activated cell group and / or reducing the energy consumption of the terminal device.

[0120] Second embodiment

[0121] 6 , which is a flow chart of a control method according to a second embodiment, based on the first embodiment of the present application, the control method further includes the following steps:

[0122] S2: Evaluation of candidate cells in the selectively activated cell group based on control information processing.

[0123] Optionally, the control information includes at least one of the following:

[0124] Activate the command for selective activation of cell group function;

[0125] Deactivate the command for selective activation of cell group function;

[0126] A secondary cell group release command containing a specific cause value;

[0127] Selectively activate the traffic conditions of candidate cells in the cell group.

[0128] Optionally, when the terminal device receives a deactivation command for the selective activation cell group function and / or a secondary cell group release command containing a specific reason value, and / or the terminal device's traffic volume does not reach the first threshold value, the candidate cells in the selective activation cell group are not evaluated.

[0129] Optionally, when the network device receives an energy-saving request or overheating report from the terminal device to release the SCG, the network device sends a command to release the SCG and a command to deactivate the CPA selective activation of the cell groups function, which can be sent through MAC CE. However, the previously configured CPA candidate cell configuration is retained, and the terminal device does not start the CPA candidate cell evaluation.

[0130] Optionally, when the terminal device is in an energy-saving state and / or an overheating state, the candidate cells in the selective activation cell group are not evaluated, that is, for a terminal device configured with the CPA selective activation of the cell groups function, when the terminal device is in an energy-saving state or an overheating state, the CPA candidate cell evaluation is not started.

[0131] Optionally, when the terminal device receives a command to activate the selective activation cell group function, and / or the terminal device traffic reaches a second threshold value, the candidate cells in the selective activation cell group are evaluated.

[0132] Optionally, when the network device receives a request from the terminal device to cancel energy saving or overheating, it sends a command to activate the CPA selective activation of the cell groups function, which can be sent through MAC CE, and the terminal device starts to start the CPA candidate cell evaluation.

[0133] Optionally, when the terminal device is not in the energy-saving state and / or the overheating state, the candidate cells in the selectively activated cell group are evaluated.

[0134] Optionally, a secondary cell group release command containing a specific cause value can be used to carry the reason for releasing the SCG, i.e., the specific cause value, including at least one of the terminal device being in an energy-saving state, the terminal device being in an overheating state, and the terminal device traffic not reaching the first threshold value.

[0135] Optionally, if the SCG is released because the terminal device traffic volume does not reach the first threshold value, the release command may also carry the traffic volume threshold for starting the CPA evaluation next time.

[0136] Optionally, when the network device decides to start the CPA selective activation of the cell groups function and configures the CPA candidate cell configuration, in addition to configuring the signal conditions for starting the CPA candidate cell evaluation (that is, in addition to the original conditional events), the uplink traffic conditions can also be configured at the same time. The CPA selective activation of the cell groups function is deactivated by default, and the terminal device does not start the CPA candidate cell evaluation. When the uplink traffic conditions of the terminal device are met, the terminal device activates the CPA selective activation of the cell groups function and starts the CPA candidate cell evaluation.

[0137] Optionally, the network device can actively send a command to activate the CPA selective activation of the cell groups function. For example, when the downlink traffic surges, the terminal device can activate the CPA selective activation of the cell groups function after receiving the command to activate the CPA selective activation of the cell groups function and start the CPA candidate cell evaluation.

[0138] Optionally, if the terminal device receives a command to deactivate the selective activation cell group function, it starts a timer.

[0139] Optionally, if the timer is in a running state, the terminal device keeps the selective activation cell group configuration information valid.

[0140] Optionally, for terminal devices configured with the CPA selective activation of the cell groups function, when the network device releases the SCG, it carries the reason for releasing the SCG (such as energy saving, overheating, the data volume does not reach a specific threshold, etc. If the SCG is released because the data volume does not reach a specific threshold, it can also carry the business volume threshold for starting the CPA evaluation next time). The previously configured CPA candidate cell configuration is still retained, and the terminal device does not start the CPA evaluation of the candidate cell.

[0141] Optionally, if the timer times out, the terminal device releases the selective activation cell group configuration information.

[0142] Optionally, when the terminal device is in an energy-saving or overheating state for a long time, in order to prevent the network device from still reserving CPA resources for the terminal device, a timer can be started when the network device sends a command to activate the CPA selective activation of the cell groups function. During the timer, the CPA candidate cell configuration remains valid. When the timer times out, if the terminal device is still in an energy-saving or overheating state, for example, the terminal device has not sent a request to cancel energy-saving or overheating, the network device and the terminal device can release the CPA resources at the same time.

[0143] Optionally, if the terminal device is not in an energy-saving state or an overheating state, the timer is stopped and the selective activation cell group configuration information is kept valid.

[0144] Optionally, when the terminal device is not in an energy-saving state or an overheating state, and / or the amount of data on the terminal device reaches a specific threshold (indicating that a large bandwidth is required at this time), the terminal device starts to initiate the CPA candidate cell evaluation. At this time, if the timer is in running state, the timer can be stopped to keep the selective activation cell group configuration information valid.

[0145] This embodiment, through the above-mentioned scheme, specifically through the evaluation of candidate cells in the selectively activated cell group based on control information processing, enables the terminal device to control the evaluation of candidate cells in the selectively activated cell group in a scenario where the SCG is released due to energy saving, overheating or low business volume, thereby avoiding the terminal device from continuously starting the evaluation of candidate cells in the selectively activated cell group, thereby reducing unnecessary evaluation of candidate cells in the selectively activated cell group, and / or avoiding the terminal device from initiating unnecessary SCG addition processes, thereby reducing the energy consumption of the terminal device.

[0146] Third embodiment

[0147] Based on any of the above embodiments, this embodiment further discloses the control method in the above embodiments.

[0148] Optionally, when the terminal device is in a single connection (SA) state, the serving cell is cell 0 (cell0), that is, the primary cell (PCell) is cell0. The network device configures the terminal device measurement process, and the terminal device reports a measurement report based on the measurement configuration. The measurement report includes cell 1 (cell1), cell 2 (cell2), cell 3 (cell3), and cell 4 (cell4).

[0149] Optionally, the network device decides to start the continuous CPA function (i.e., the NR-DC selective activation cell group function), configures the CPA candidate cell cell1, cell2, cell3, and cell4 condition configuration and corresponding execution conditions for the terminal device, and the terminal device starts the CPA candidate cell evaluation.

[0150] Optionally, cell1 meets the CPA candidate cell execution conditions, the terminal device executes CPA, and the condition configuration corresponding to cell1 is applied. The condition configuration and execution conditions of other CPA candidate cells (i.e., cell2, cell3, and cell4) remain. At this time, the terminal device is in the NR-DC (New Radio-Dual Connectivity) state, the PCell is cell0, and the primary secondary cell (Primary SCG Cell, PSCell) is cell1.

[0151] Optionally, when the terminal device is in energy-saving state, it sends UEAssistanceInformation, optionally with maxBW-Preference and maxCC-Preference set to 0, requesting the network device to release the SCG. The network device issues a command to release cell1 and deactivates the continuous CPA function. However, the condition configuration and execution conditions of candidate cells cell1, cell2, cell3, and cell4 remain, but the terminal device does not start CPA evaluation.

[0152] Optionally, when the terminal device is in an overheating state, it sends a UEAssistanceInformation message carrying OverheatingAssistance, requesting the network device to reduce the maximum CC or aggregate bandwidth and release the SCG. The network device issues a command to release cell1 and deactivates the continuous CPA function. The condition configuration and execution conditions of candidate cells cell1, cell2, cell3, and cell4 remain, but the terminal device does not initiate CPA evaluation.

[0153] Optionally, the network device issues a CPA candidate configuration validity timer. The candidate cell configuration and execution conditions remain valid before the timer expires. When the timer expires, the terminal device releases the saved CPA candidate cell configuration.

[0154] Optionally, when the terminal device leaves the energy-saving state or overheats, the terminal device sends UEAssistanceInformation. Optionally, maxBW-Preference and maxCC-Preference are not 0 or do not include OverheatingAssistance. At this time, if the CPA candidate configuration validity timer is still running, the corresponding timer is stopped. The network device sends a command to activate the continuous CPA function, and the terminal device starts CPA candidate cell evaluation.

[0155] This embodiment uses the above-mentioned scheme, specifically by sending corresponding control information based on the status of the terminal device through the network device, so that the terminal device does not start the CPA candidate cell evaluation in the energy-saving state and / or overheating state, thereby reducing unnecessary candidate cell evaluations, and / or avoiding the terminal device from initiating unnecessary SCG addition processes, and controlling whether the candidate cell configuration and execution conditions are valid through a timer, thereby reducing the energy consumption of the terminal device.

[0156] Fourth embodiment

[0157] Based on any of the above embodiments, this embodiment further discloses the control method in the above embodiments.

[0158] Optionally, when the terminal device is in SA state, the serving cell is cell0, that is, PCell is cell0. Cell0 configures the terminal device measurement process, and the terminal device reports a measurement report according to the measurement configuration. The measurement report includes cell1, cell2, cell3, and cell4.

[0159] Optionally, the network device decides to start the continuous CPA function (i.e., the NR-DC selective activation cell group function), configures the CPA candidate cell cell1, cell2, cell3, and cell4 condition configuration and corresponding execution conditions for the terminal device, and the terminal device starts the CPA candidate cell evaluation.

[0160] Optionally, if cell 1 meets the CPA candidate cell execution conditions, the terminal device executes CPA and applies the condition configuration corresponding to cell 1. The condition configuration and execution conditions of other CPA candidate cells (i.e., cell 2, cell 3, and cell 4) remain unchanged. At this time, the terminal device is in the NRDC state, with PCell 0 and PSCell 1.

[0161] Optionally, when the network device releases the SCG (for example, because the business volume does not meet specific requirements, or the terminal device is in energy-saving state, overheating state, etc.), the network device issues a command to release cell1 and carries a specific reason value (such as energy saving, overheating, low business volume, etc., if it is due to low business volume, it can also carry the business volume threshold), but the candidate cells cell1, cell2, cell3, cell4 condition configuration and execution conditions are still retained, but the terminal device does not start the CPA evaluation.

[0162] Optionally, the execution condition may include a traffic volume condition, and the terminal device starts the CPA candidate cell evaluation only when the terminal device traffic volume condition is also met.

[0163] Optionally, if the current terminal device traffic volume is small (e.g., only web browsing) and does not reach a specific threshold, the terminal device does not initiate CPA candidate cell evaluation. If the terminal device traffic volume increases (e.g., browsing and downloading videos) and reaches a specific threshold, the terminal device initiates CPA candidate cell evaluation.

[0164] This embodiment uses the above solution to dynamically control the terminal device's evaluation of CPA candidate cells based on the terminal device's traffic volume. The terminal device initiates CPA candidate cell evaluation only when the terminal device's traffic volume conditions are also met. This avoids the terminal device from initiating unnecessary candidate cell evaluation when the traffic volume is low, improves the flexibility of candidate cell evaluation, and reduces terminal device energy consumption.

[0183] Optionally, when the terminal device is not in the energy-saving state and / or the overheating state, the candidate cells in the selectively activated cell group are evaluated.

[0184] Optionally, a secondary cell group release command containing a specific cause value can be used to carry the reason for releasing the SCG, i.e., the specific cause value, including at least one of the terminal device being in an energy-saving state, the terminal device being in an overheating state, and the terminal device traffic not reaching the first threshold value.

[0185] Optionally, if the SCG is released because the terminal device traffic volume does not reach the first threshold value, the release command may also carry the traffic volume threshold for starting the CPA evaluation next time.

[0186] Optionally, when the network device decides to start the CPA selective activation of the cell groups function and configures the CPA candidate cell configuration, in addition to configuring the signal conditions for starting the CPA candidate cell evaluation (that is, in addition to the original conditional events), the uplink traffic conditions can also be configured at the same time.

For example, the terminal device's traffic volume does not reach the first threshold value. Optionally, the traffic volume can be the amount of data to be transmitted at the terminal device's application layer, or the initial amount of data to be transmitted at the PDCP (Packet Data Convergence Protocol) layer and / or the amount of data at the RLC (Radio Link Control) layer, or the sum of the two, or the uplink data diversion traffic volume threshold when the terminal device releases the SCG, etc. This is not specifically limited in the embodiments of the present application. The specific first threshold value can be the number of bytes of data to be transmitted, such as 800 bytes, 1600 bytes or 3200 bytes, etc., which is determined by the network device according to actual conditions.

[0211] Optionally, when the terminal device receives a command to activate the selective activation cell group function, and / or the terminal device's traffic volume reaches a second threshold value, the candidate cells in the selective activation cell group are evaluated. For example, the terminal device's traffic volume reaches a second threshold value. Optionally, the second threshold value may be the same as or different from the first threshold value. The traffic volume may be the amount of data to be transmitted at the terminal device's application layer, or the initial amount of PDCP layer data and / or RLC layer data to be transmitted, or the sum of the two, or the uplink data diversion traffic volume threshold when the terminal releases the SCG, etc. This is not specifically limited in the embodiments of the present application. The specific second threshold value may be the number of bytes of data to be transmitted, such as 800 bytes, 1600 bytes or 3200 bytes, etc., which is determined by the network device according to actual conditions.

[0212] This embodiment uses the above-mentioned scheme, specifically by sending control information to the terminal device through the network device, so that the terminal device processes the evaluation of candidate cells in the selective activation cell group based on the control information, so that the terminal device controls the evaluation of candidate cells in the selective activation cell group in the scenario where the SCG is released due to energy saving, overheating or low business volume, thereby avoiding the terminal device from continuously starting the evaluation of candidate cells in the selective activation cell group, thereby reducing unnecessary evaluation of candidate cells in the selective activation cell group, and / or avoiding the terminal device from initiating unnecessary SCG addition processes, thereby reducing the energy consumption of the terminal device.
