Description

Technical Field

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

[0002] Measurement delay refers to the time required for the UE to perform measurements, trigger measurement reports, and trigger cell handover after a better cell appears, which contributes to the overall mobility delay.

[0003] During the process of conceiving and implementing the present application, the inventors discovered that there are at least the following problems: In the current LTM (L1 / L2-triggered mobility), the L1 measurement delay is part of the overall mobility delay. Assuming that L1 measurement / reporting is used to trigger LTM to reduce the measurement delay, frequent ping-pong switching may occur due to unstable L1 measurement.

[0004] Therefore, a solution is needed to solve the technical problem of ping-pong handover caused by using L1 measurement / reporting to trigger LTM, thereby reducing mobility delay.

[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the Invention

[0083] See also 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: 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 Figure 1 The structure of the mobile terminal shown in the figure does not constitute a limitation to the mobile terminal. The mobile terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0084] The following combination Figure 1 A detailed introduction to the various components of the mobile terminal:

[0085] 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 can 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) and 5G, etc.

[0086] WiFi is a short-range wireless transmission technology. Mobile terminals can help users send and receive emails, browse web pages, and access streaming media through the WiFi module 102. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not an essential component of the mobile terminal and can be omitted as needed without changing the essence of the invention.

[0087] 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.

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.

[0089] 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.

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.

[0092] Optionally, the touch panel 1071 may cover 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 according to the type of touch event. Figure 1 In the embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal, which is not limited here.

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.

[0095] 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.

[0096] 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.

[0114] The processing method of the embodiment of the present application can be applied to a terminal (such as a mobile phone) or to a network device (such as a base station).

[0115] This embodiment takes into account that, assuming that L1 measurement / reporting is used to trigger L1 / L2 inter-cell mobility to reduce measurement delay, frequent ping-pong handovers may occur due to unstable L1 measurements. To reduce ping-pong handovers, measurement hysteresis (a parameter used in the entry and exit conditions of event trigger reporting conditions), measurement trigger time (TimeToTrigger, the time that the specific criteria of an event need to be met in order to trigger a measurement report), and filter coefficient (filterCoefficient, measurement filter coefficient) can be introduced for L1 measurement and reporting. However, the introduction of Hysteresis, TimeToTrigger, and filterCoefficient may also cause measurement delay. Therefore, it is necessary to reduce the impact of ping-pong handovers and / or measurement delay. In addition, it is also necessary to consider that ping-pong handovers have different effects on L1 / L2 inter-cell mobility in different scenarios (inter-DU / intra-DU).

[0116] Optionally, for the LTM continuous mobility scenario, that is, after the terminal performs L1 / L2 inter-cell mobility, the terminal retains the previous candidate cell configuration and continues to perform LTM.

[0117] The solution of the embodiment of the present application can solve the problem of the impact of ping-pong handover caused by using L1 measurement / reporting to trigger LTM, reduce the impact of ping-pong handover on L1 / L2 inter-cell mobility, and / or reduce measurement delay and / or signaling overhead.

[0118] In this embodiment, the candidate cell grouping information is sent by a network device, so that the terminal performs a preset process based on the candidate cell grouping information.

[0119] Optionally, the candidate cell grouping information means that the candidate cells in the same DU are in the same group and / or the candidate cells in different DUs are in different groups. For example, the network device can assign a group ID to each candidate cell, assign the same group ID to the candidate cells in the same DU, and / or assign different group IDs to the candidate cells in different DUs.

[0120] Optionally, the candidate cell grouping information is sent by a network device, and the terminal receives the candidate cell grouping information sent by the network device and performs a preset process based on the candidate cell grouping information.

[0121] Optionally, the preset processing includes: performing L1 / L2-based inter-cell mobility.

[0122] Optionally, performing L1 / L2-based inter-cell mobility may include: the terminal performing L1 / L2-based inter-cell mobility measurement, measurement reporting, the network device issuing a switching command based on the measurement report and / or the terminal performing inter-cell switching after receiving the switching command and performing RLC reconstruction, MAC restart, etc.

[0123] Compared with the prior art, in the technical solution of the present application, candidate cell grouping information is sent by a network device, and the terminal performs preset processing based on the candidate cell grouping information. There is no need to reconfigure the measurement configuration from the current serving cell to other candidate cells each time, which can reduce the impact of ping-pong switching on L1 / L2 inter-cell mobility, and / or reduce measurement delay and / or signaling overhead.

[0124] Reference Figure 6 As shown, the second embodiment of the present application proposes a processing method based on the above Figure 5 Based on the embodiment shown, step S20 includes the following steps:

[0125] S21: The terminal determines processing parameters based on the serving cell and candidate cell grouping information;

[0126] S22: The terminal performs a preset process based on the processing parameters.

[0127] In one implementation, in a scenario where the terminal performs L1 / L2-based inter-cell mobility based on candidate cell grouping information, the processing parameters include measurement parameters.

[0128] Optionally, step S20 may include the following steps:

[0129] The terminal determines the measurement parameters according to the serving cell and candidate cell grouping information;

[0130] The terminal performs L1 / L2-based inter-cell mobility measurement and reporting based on the measurement parameters.

[0131] Optionally, the measurement parameters include at least one of the following:

[0132] Measure hysteresis;

[0133] Measure the trigger time timeToTrigger;

[0134] Filter coefficient filterCoefficient.

[0135] Optionally, before the step S21, the method further includes: the terminal determining or judging whether to determine a processing parameter according to the candidate cell grouping information.

[0136] Optionally, the terminal determines or judges whether to determine the measurement parameter according to the candidate cell grouping information.

[0137] Optionally, considering that ping-pong handover has different impacts on L1 / L2 inter-cell mobility in different scenarios (inter-DU / intra-DU), this embodiment performs corresponding grouping based on whether the candidate cells are in the same DU, with the aim of reducing mobility delay and reducing measurement delay while reducing ping-pong handover.

[0138] Optionally, the embodiment of the present application further includes at least one of the following:

[0139] Candidate cells in the same DU are in the same group;

[0140] Candidate cells in different DUs are in different groups;

[0141] The candidate cells include the current serving cell.

[0142] Optionally, the network device may assign a group ID to each candidate cell, assign the same group ID to candidate cells in the same DU, and / or assign different group IDs to candidate cells in different DUs.

[0143] Optionally, the step S21 includes at least one of the following:

[0144] When the candidate cell and the current serving cell are in the same group, the first set of processing parameters is used;

[0145] When the candidate cell and the current serving cell are not in the same group, the second set of processing parameters is used;

[0146] When the candidate cell and the current serving cell are in the same group, measurement hysteresis and / or measurement trigger time and / or filter coefficient are not used;

[0147] When the candidate cell and the current serving cell are in the same group, a first preset value of measurement hysteresis and / or measurement trigger time and / or filter coefficient is used;

[0148] When the candidate cell and the current serving cell are in different groups, measurement hysteresis and / or measurement trigger time and / or filter coefficient are used;

[0149] When the candidate cell and the current serving cell are in different groups, the measurement hysteresis and / or measurement trigger time and / or filter coefficient of the second preset value are adopted.

[0150] Optionally, the second preset value is greater than the first preset value.

[0151] Optionally, for the intra-DU scenario, since the serving cell and the candidate cell share the same SDAP / PDCP / RLC / MAC configuration, the ping-pong handover has little impact on the intra-DU, and Hysteresis, TimeToTrigger, and filterCoefficient may not be used or may be smaller.

[0152] Optionally, for the intra-CU inter-DU scenario, since the RLC / MAC of the serving cell and the candidate cell are located in different DUs, RLC reconstruction and MAC restart are required during switching. Therefore, ping-pong switching has a great impact on the intra-DU. In order to reduce ping-pong switching, a larger Hysteresis, TimeToTrigger, and filterCoefficient can be used.

[0153] Optionally, since the UE does not know whether the candidate cell and the serving cell share a DU, the network can group the candidate cells according to their DUs when configuring the candidate cells. When performing L1 measurement and reporting for cells in the same DU group, smaller Hysteresis, TimeToTrigger, and filterCoefficient may not be used / used. When performing L1 measurement and reporting for cells in different DU groups, larger Hysteresis, TimeToTrigger, and filterCoefficient may be used / used.

[0154] Optionally, step S20 further includes at least one of the following:

[0155] The terminal does not perform RLC reestablishment and / or MAC restart and / or partial MAC restart for intra-packet cell handover;

[0156] For inter-packet and inter-cell handover, the terminal performs RLC re-establishment and / or MAC restart and / or partial MAC restart.

[0157] The third embodiment of the present application further proposes a processing method. Based on the above corresponding embodiment, in an implementation of this embodiment, the terminal performs L1 / L2-based inter-cell mobility based on the measurement parameter, including:

[0158] The terminal determines whether the candidate cell meets the measurement report reporting conditions based on the measurement parameters; if it is determined that the candidate cell meets the measurement report reporting conditions, the terminal sends an L1 measurement report to the network device, so that the network device can perform L1 / L2-based inter-cell mobility according to the measurement report, and / or, so that the network device can issue a command to activate or delete the candidate cell.

[0159] Optionally, the network device performing L1 / L2-based inter-cell mobility according to the measurement report includes:

[0160] The network device issues a handover command according to the measurement report reported by the terminal, and performs L1 / L2-based inter-cell mobility, so that the terminal performs L1 / L2-based inter-cell handover after receiving the handover command.

[0161] Optionally, the measurement report includes measurement results of other candidate cells other than the candidate cells that meet the measurement report reporting conditions.

[0162] Optionally, the terminal receives a switching command sent by the network device, and performs L1 / L2-based inter-cell switching according to the switching command.

[0163] Optionally, at least one of the following is also included:

[0164] The network device issues a command to deactivate or delete the candidate cell based on the measurement report and / or the neighboring relationship between the serving cell or the cell to be switched and the candidate cell or the switching record; optionally, the measurement report is sent by the terminal after determining that the candidate cell meets the measurement report reporting conditions based on the processing parameters.

[0165] The terminal receives a deactivation or deletion command sent by the network device, and does not perform L1 measurement on the deactivated or deleted candidate cell according to the deactivation or deletion command.

[0166] Optionally, at least one of the following is also included:

[0167] When the measurement report does not include the measurement results of the candidate cell, the network device issues a command to deactivate or delete the candidate cell;

[0168] When the measurement result of the candidate cell is lower than the set threshold, the network device sends a command to activate or delete the candidate cell;

[0169] When the candidate cell is not in the neighboring cell list of the current serving cell or the cell to be switched, the network device sends a command to activate or delete the candidate cell;

[0170] When there is no handover record between the candidate cell and the current serving cell or the cell to be handed over, the network device sends a command to activate or delete the candidate cell;

[0171] When the deactivated candidate cell is in the neighboring cell list of the current serving cell or the cell to be switched, the network device issues a command to activate the candidate cell;

[0172] Optionally, the deactivation or deletion command or the activation command is issued via a switching command of the network device.

[0173] Optionally, based on the terminal measurement results or the neighboring relationship between the candidate cell and the current serving cell or the cell to be switched, the network device dynamically adjusts the activation status of the candidate cell or the network releases some candidate cells, and the terminal only performs L1 measurement on the candidate cells in the activated state or in the candidate cell list.

[0174] In the technical solution of the embodiment of the present application, candidate cell grouping information is sent by a network device, and the terminal performs L1 / L2-based inter-cell mobility based on the candidate cell grouping information. There is no need to reconfigure the measurement configuration from the current serving cell to other candidate cells each time, which can reduce the impact of ping-pong switching on L1 / L2 inter-cell mobility and / or reduce measurement delay and / or signaling overhead.

[0175] In one implementation of this embodiment, the specific process is as follows:

[0176] 1. The source cell / source gNB / CU to which the source cell belongs configures the UE measurement procedure, and the UE reports the measurement report according to the measurement configuration.

[0177] 2. The source cell / source gNB / CU to which the source cell belongs decides to perform L1 / L2 inter-cell mobility;

[0178] The source cell / source gNB / CU to which the source cell belongs prepares one or more L1 / L2 inter-cellmobility candidate cell configurations based on the measurement report, and groups them according to the serving cell and the DUs to which the candidate cells belong. Cells with the same DU are grouped together.

[0179] 3. The source cell / source gNB / CU to which the source cell belongs sends the L1 / L2 inter-cell mobility candidate cell configuration and grouping information to the UE through an RRCReconfiguration message;

[0180] 4. The UE performs L1 measurement and does not use or uses a smaller Hysteresis& / TimeToTrigger& / filterCoefficient for candidate cells with the same DU as the current serving cell. It uses or uses a larger Hysteresis& / TimeToTrigger& / filterCoefficient for candidate cells with different DUs as the current serving cell.

[0181] 5. When the L1 measurement reporting conditions are met, the L1 measurement reporting is triggered and the network device sends a MAC CE to trigger LTM. For intra-packet LTM cell handover, the UE does not perform RLC re-establishment and / or MAC restart and / or partial MAC restart; and / or, for inter-packet inter-cell handover, the UE performs RLC re-establishment and / or MAC restart and / or partial MAC restart;

[0182] 6. The network device dynamically adjusts the activation / deletion status of candidate cells (which can be sent together through L1 / / L2 cell switchcmd). The UE only performs L1 measurement on candidate cells in the activation state / candidate cell list.

[0183] For example, the status of the candidate cell is dynamically adjusted according to the UE measurement result and / or the geographical location or neighboring cell relationship between the candidate cell and the current serving cell.

[0184] Optionally, if the UE L1 measurement result does not include measurement results of certain candidate cells (meaning that the signals of these candidate cells do not meet the measurement reporting conditions or the UE cannot measure the signals) or the measurement results are lower than a specific threshold, the network device deactivates / deletes these candidate cells.

[0185] Optionally, if some candidate cells are not in the neighboring cell list of the current serving cell or the cell to be switched or have no historical switching records, the network device deactivates / deletes these candidate cells.

[0186] For the deactivation scenario, if the deactivated cells are in the neighboring cell list of the serving cell / cell to be switched after LTM, the network device activates these cells.

[0187] For the deletion scenario, the initial candidate information preparation process (ie, steps 1 to 3) is used to add these cells to the candidate cell list.

[0188] The following combination Figure 7 This application plan is elaborated in detail. The specific process is as follows:

[0189] like Figure 7 As shown, the current serving cell is cell 0, that is, the source cell is cell 0. Cell 0 configures the UE measurement process, and the UE reports a measurement report based on the measurement configuration. The measurement report includes cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6.

[0190] Based on the measurement report, the source cell prepares candidate cell configurations for L1 / L2 inter-cell mobility: cells 1, 2, 3, 4, 5, and 6. The source cell then groups the candidate cells according to the DUs to which they belong, grouping cells with the same DU. By default, the current serving cell, cell 0, belongs to DU group 0. Cells 1 and 2 belong to DU group 1, cells 3 and 4 belong to DU group 0, and cells 5 and 6 belong to DU group 2.

[0191] The source cell sends the L1 / L2 inter-cell mobility candidate cell configuration and grouping information to the UE through the RRCReconfiguration message.

[0192] The UE performs L1 measurement and does not use or uses a smaller Hysteresis& / TimeToTrigger& / filterCoefficient for candidate cells with the same DU as the current serving cell (such as cell3 and cell4). It uses or uses a larger Hysteresis& / TimeToTrigger& / filterCoefficient for candidate cells with different DUs as the current serving cell (cell5 and cell6).

[0193] When a cell (such as cell2) meets the L1 measurement reporting conditions, the UE reports the L1 measurement report, the network performs L1 / L2 inter-cell mobility, sends L1 / L2 cell switch signaling, and the UE performs L1 / L2 inter-cell mobility handover to cell2. For intra-group LTM cell handover, the UE does not perform RLC re-establishment and / or (partial) MAC restart; and / or, for inter-group inter-cell handover, the UE performs RLC re-establishment and / or (partial) MAC restart. After the handover, some or all candidate cell configurations and grouping information are retained.

[0194] Cell2 determines that cell5 and cell6 are not in the current neighboring cell list or have no historical switching records, and sends a command to deactivate / delete candidate cells of cell5 and cell6 (which can be sent together with the L1 / L2 cell switch or after the switch). The UE does not perform L1 measurement on cell5 and cell6.

[0195] The UE performs L1 measurement and does not use or uses a smaller Hysteresis& / TimeToTrigger& / filterCoefficient for candidate cells with the same DU as the current serving cell (e.g., cell1). It uses or uses a larger Hysteresis& / TimeToTrigger& / filterCoefficient for candidate cells with different DUs as the current serving cell (e.g., cell3, cell4).

[0196] In the technical solution of the embodiment of the present application, candidate cell grouping information is sent by a network device, and the terminal performs L1 / L2-based inter-cell mobility based on the candidate cell grouping information. There is no need to reconfigure the measurement configuration from the current serving cell to other candidate cells each time, which can reduce the impact of ping-pong switching on L1 / L2 inter-cell mobility and / or reduce measurement delay and / or signaling overhead.

[0208] When the candidate cell and the current serving cell are in the same group, measurement hysteresis and / or measurement trigger time and / or filter coefficient are not used;

[0209] When the candidate cell and the current serving cell are in the same group, a first preset value of measurement hysteresis and / or measurement trigger time and / or filter coefficient is used;

[0210] When the candidate cell and the current serving cell are in different groups, measurement hysteresis and / or measurement trigger time and / or filter coefficient are used;

[0211] When the candidate cell and the current serving cell are in different groups, the measurement hysteresis and / or measurement trigger time and / or filter coefficient of the second preset value are adopted.

[0212] Optionally, include at least one of the following:

[0215] Based on the processing parameters, it is determined whether the candidate cell meets the measurement report reporting conditions. If so, the L1 measurement report is sent so that the network device can perform L1 / L2-based inter-cell mobility according to the measurement report, and / or so that the network device can issue a command to activate or delete the candidate cell.
