[0134] Implementation Methods of the Application

[0135] 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.

[0136] It should be noted that, in this document, the terms "comprises", "includes" 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 "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element, and / or, 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.

[0137] 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 only to distinguish information of the same type from one another. For example, without departing from the scope of this document, 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 "when...", "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 described features, steps, operations, elements, components, items, types, and / or groups, but do not exclude 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., used herein, may be interpreted as inclusive, or mean 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] The communication device in this application can be a terminal device (such as a mobile phone), a first network device (such as a base station), or a second network device (such as a base station). The specific reference needs to be clarified according to the context.

[0146] 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.

[0147] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0148] 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. Furthermore, it 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 / or other components. 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.

[0149] 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 altering the essence of the invention.

[0150] 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.

[0151] 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.

[0152] 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 identify 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.

[0153] 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.

[0154] The user input unit 107 can be used to receive input digital or character information and generate key signal input related to 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 corresponding connected devices 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 and execute commands sent by the processor 110. And / or, 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.

[0155] 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.

[0156] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100.

Referring to Figure 6, Figure 6 is a flow chart of the processing method according to the second embodiment, and the specific steps include:

[0225] S0: Send pre-configuration information to the terminal device.

[0226] In existing protocols, when a terminal device receives a Conditional Handover (CHO) configuration from a network device and sends a configuration completion signaling signal to the source gNB, the source gNB can perform early data forwarding after completing the CHO configuration to reduce data transmission delays during handover. However, if enhanced conditional handover is used in LTM handover scenarios, the source gNB cannot clearly know which candidate gNB the terminal device will switch to, and therefore cannot perform early data forwarding, which will also cause data transmission delays.

[0227] In the embodiment of the present application, the first indication information is used to enable the first network device to clearly know that the terminal device is about to switch to the second network device, thereby performing early data forwarding to the first network device.

[0228] Optionally, the source cell (first network device) obtains pre-configuration information (LTM-Candidate) of at least one candidate cell (second network device), including: conditional handover configuration and / or conditional LTM handover configuration (ltm-condCandidateConfig) of the candidate cell.

[0229] Optionally, the conditional switching configuration includes a conditional execution condition (ConditionalExecution condition) configuration and / or a conditional switching measurement configuration.

[0230] Optionally, the conditional LTM switching configuration includes a conditional execution condition configuration and / or a conditional switching measurement configuration.

[0231] Optionally, the conditional switching measurement configuration includes: a measurement event (Event) and / or a measurement threshold (Threshold).

[0232] Optionally, the conditional switching measurement configuration is used by the network device to perform early data forwarding, and therefore, may also be referred to as an early data forwarding measurement configuration, which is not limited in the embodiments of the present application.

[0233] Optionally, the measurement event and / or the measurement threshold is used to determine whether the measured cell enters a service range, that is, whether the measurement result enters a predetermined range or meets a threshold.

[0234] Optionally, the measurement event is a new measurement event, such as Event A7, or an existing measurement event, such as Event A3 / A4, which is not limited in the embodiments of the present application.

[0235] Optionally, the new measurement event is used to indicate that the target cell measurement result enters a preset range, for example: the target cell signal strength is greater than a signal strength threshold, the target cell signal quality is greater than a signal quality threshold, or the target cell signal-to-noise ratio is greater than a signal-to-noise ratio threshold.

[0236] Optionally, the measurement threshold includes: an entry range threshold, where the entry range threshold is used to indicate that the target cell measurement result enters a preset range, for example: the target cell signal strength is greater than the signal strength entry range threshold, the target cell signal quality is greater than the signal quality entry range threshold, and the target cell signal-to-noise ratio is greater than the signal-to-noise ratio entry range threshold.

[0237] Optionally, the new measurement event is used to indicate that the target cell measurement result enters a preset range, and also includes the target cell measurement result and / or the target cell measurement result plus a specific offset value is higher than the serving cell measurement result, for example: the target cell signal strength measurement result plus the signal strength offset value is greater than the serving cell signal strength measurement result, the target cell signal quality measurement result plus the signal quality offset value is greater than the serving cell signal quality measurement result, and the target cell signal-to-noise ratio measurement result plus the signal-to-noise ratio offset value is greater than the serving cell signal-to-noise ratio measurement result.

[0238] Optionally, the conditional handover measurement configuration is further used to provide a source cell with a decision on executing early data forwarding.

[0240] Optionally, the reference signal measurement configuration includes: at least one of: measurement resources, measurement carrier, physical cell identity (PCI), reporting resources, and serving cell identity (Serving Cell Identity).

[0241] Optionally, the measurement configuration includes at least one of a measurement event, a measurement carrier, and a reporting configuration.

[0242] Optionally, the conditional execution condition is configured to trigger a conditional switch and / or a conditional LTM switch.

[0243] Optionally, the measurement event includes a conditional switching measurement event.

[0244] Optionally, the setting conditions for the conditional switch measurement configuration are looser than the conditional execution condition configuration, for example:

[0245] In the measurement event of the conditional handover measurement configuration, the measurement specific compensation value of the neighboring cell is greater than the measurement specific compensation value of the neighboring cell in the measurement event of the conditional execution condition configuration. Therefore, the measurement result of the neighboring cell preferably satisfies the conditional handover measurement configuration.

[0246] The measurement threshold in the conditional handover measurement configuration is smaller than the specific compensation value for neighbor cell measurement in the conditional execution condition configuration. Therefore, the neighbor cell measurement result preferentially satisfies the conditional handover measurement configuration.

[0247] Optionally, the measurement event or the measurement threshold may be at least one of signal strength (RSRP), signal quality (RSRQ) and signal-to-noise ratio (SINR).

[0248] Optionally, the candidate cell conditional switching configuration information also includes: at least one of: early uplink synchronization configuration (EarlyUL-SyncConfig), configuration scheduling configuration (ConfiguredGrantConfig), candidate cell complete configuration indication (ltm-ConfigComplete) and new terminal radio temporary identity (newUE-Identity).

[0249] Optionally, the layer 1 measurement configuration includes: LTM channel state information resource configuration (LTM-CSI-ResourceConfig) and / or LTM channel state information report configuration (LTM-CSI-ReportConfig).

[0250] Optionally, the configuration scheduling configuration is also associated with beam information (TCI-State).

[0251] Optionally, the configuration scheduling configuration includes: configuring scheduling type 1 (CG Type 1).

[0252] Optionally, the candidate cells include cells in legacy R17 and earlier versions and / or LTM cells.

[0253] Optionally, the candidate cell configuration information is distinguished by an identifier, for example, at least one of a conditional handover configuration identifier (condReconfigID), an LTM candidate identifier (LTM-CandidateId), and an LTM conditional candidate identifier (LTM-condCandidateId).

[0254] Optionally, the conditional execution condition configuration and / or conditional switching measurement configuration is also applicable to the serving cell, for example, the serving cell meets measurement event A2 and / or event A5 and / or periodic reporting. For details, please refer to the existing technology, for example: protocol TS 38.331, section 5.5.4.

[0255] Optionally, the source cell (first network device) sends at least one candidate cell conditional switching configuration information through RRC reconfiguration signaling.

[0256] Optionally, when the candidate cell conditional switching configuration includes terminal device measurement time advance configuration, it indicates that the underlying terminal device is configured with terminal device measurement time advance and / or performs candidate cell time advance measurement.

[0257] Optionally, the terminal device receives at least one candidate cell conditional switching configuration information and stores it locally.

[0258] Optionally, the candidate cell conditional handover configuration information is pre-configured information and is used for continuous handover.

[0259] Optionally, the terminal device sends an RRC reconfiguration completion (RRCReconfigurationComplete) to the source cell.

[0260] Optionally, the terminal device switches the measurement configuration according to the condition to perform the measurement.

[0261] Optionally, the terminal device evaluates whether the candidate cell meets the conditional switching measurement configuration based on the measurement result, for example, judging whether the measurement event parameters are met and / or whether the measurement result is greater than a threshold based on the candidate cell measurement result, for example, the candidate cell measurement result meets the measurement event Event A7, and / or the candidate cell measurement result meets the measurement threshold.

[0262] Optionally, the terminal device synchronously evaluates whether the measurement result meets the conditional execution condition, for example, judging whether the measurement configuration is met based on the candidate cell measurement result, including: the candidate cell measurement result meets the measurement event.

[0263] Optionally, the terminal device evaluates whether at least one candidate cell satisfies the conditional handover measurement configuration, for example, the measurement result of at least one candidate cell satisfies at least one of the following:

[0264] The target cell signal strength is greater than the signal strength threshold, the target cell signal quality is greater than the signal quality threshold, and the target cell signal-to-noise ratio is greater than the signal-to-noise ratio threshold;

[0265] The target cell signal strength is greater than the signal strength entry range threshold, the target cell signal quality is greater than the signal quality entry range threshold, and the target cell signal-to-noise ratio is greater than the signal-to-noise ratio entry range threshold.

[0266] Through the technical solution of this embodiment, pre-configuration information is sent to the terminal device through the first network device, new measurement events are introduced and / or existing measurement events are enhanced to determine whether the candidate cell enters the measurement reporting range. When there is at least one candidate cell entering the reporting range, early uplink synchronization and / or reporting indication information is performed, so that the first network device determines the second network device to which the terminal device is about to switch, and then performs early data forwarding, which improves the mechanism of random access condition-free switching and / or random access condition-free LTM switching, so that the early data forwarding method can be applied to a variety of switching scenarios, improves the applicability of the early data forwarding method, and / or helps to reduce the data transmission delay during the switching process.

[0335] Optionally, the current serving cell receives the response information and sends early data forwarding signaling as feedback to the third network device to perform early data forwarding.

[0336] Optionally, when there is at least one other candidate cell (including a third network device) that meets the conditions for switching the measurement configuration, the terminal device can also send a measurement report (indication information) to the current serving cell (i.e., the second network device), thereby enabling the second network device to perform early data forwarding according to the indication information.

[0337] Optionally, the terminal device continuously evaluates whether there are candidate cells that meet the conditions to execute conditional configuration.

[0338] Optionally, when at least one candidate cell (including the third network device) meets the conditional execution condition configuration, the terminal device initiates a conditional switching process for the third network device.
