Description

Technical Field

[0002] In New Radio (NR) for 5th Generation (5G) mobile communication technology, terminal equipment should conventionally measure reference signals from one or more cells for BFD (Bidirectional Forwarding Detection) or RLM (Radio Link Monitoring). If the terminal equipment is in a low-mobility state, it is unnecessary to maintain measurements in the conventional manner to save power consumed by the measurements. This leads to a low-mobility assessment; for terminal equipment that meets the low-mobility requirement, a BFD / RLM relaxation mechanism (measurement relaxation) will be implemented, for example, by extending the measurement cycle of the terminal equipment.

[0003] Low mobility assessment is defined as: within a certain time period (T) SearchDeltaP Within a certain range, if the difference between the received power of the reference signal and the reference value is less than a preset threshold (S) SearchDeltaP If the signal change is small, it means that the terminal device is considered to be stationary or in a low-mobility state.

These terms are only used to distinguish information of the same type from one another. For example, a first parameter may also be referred to as a second parameter without departing from the scope of this disclosure, and similarly, a second parameter may also be referred to as a first parameter.

[0037] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, data stored, data displayed, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0038] Please refer to Figure 1 The diagram illustrates a system architecture provided in one embodiment of this application. This system architecture may include: a terminal device 10 and a network device 20.

[0039] The number of terminal devices 10 is typically multiple, and one or more terminal devices 10 can be distributed within the cell managed by each network device 20. Terminal devices 10 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For ease of description, in this embodiment, the devices mentioned above are collectively referred to as terminal devices.

[0040] Network device 00 and terminal device 10 can establish a connection through the air interface, thereby communicating through the connection, including the exchange of signaling and data.

[0041] Network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the names of devices with network device functionality may differ; for example, in a 5G NR system, they are called gNodeB or gNB. As communication technologies evolve, the term "base station" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as network devices. There can be multiple network devices 10, and two adjacent network devices 10 can communicate with each other via wired or wireless means. Terminal device 20 can switch between different network devices 10, that is, establish connections with different network devices 10.

[0042] The "5G NR system" in this disclosure can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this disclosure are applicable to 5G NR systems and also to subsequent evolution systems of 5G NR systems.

[0043] Taking 5G mobile communication technology as an example, in the early stages of NR deployment, complete NR coverage was difficult to achieve. Typical network coverage consisted of wide-area Long Term Evolution (LTE) coverage and isolated NR coverage. A large amount of LTE deployment was below 6GHz, leaving very little spectrum available for 5G. To protect mobile operators' initial investments in LTE, a tight interworking model between LTE and NR was proposed. Taking LTE-NR Dual Connectivity (EN-DC) as an example... Figure 2 A schematic diagram of the EN-DC network architecture is shown. LTE acts as the MN (Master Node), and NR acts as the SN (Secondary Node). The MN is primarily used to implement RRC control functions and the control plane leading to the CN (Core Network), while the SN is used to configure auxiliary signaling, such as the third radio signaling bearer (SRB3), which mainly provides data transmission functions.

[0044] The primary cell of a Name Node (MN) is called the Primary Cell (PCell), and its secondary cells are called Secondary Cells (SCells). All cells associated with an MN belong to the Master Cell Group (MCG). Similarly, the primary cell of a Secondary Node (SN) is called the Primary Secondary Cell (PSCell), and its secondary cells are called Secondary Cells (SCells). All cells associated with an SN belong to the Secondary Cell Group (SCG). Figure 3 A schematic diagram of the MCG and SCG structures is shown.

[0045] Release 17 (R17) introduced a relaxation mechanism for Bidirectional Forwarding Detection (BFD) and Radio Link Monitoring (RLM). This means that for terminal devices that meet the relaxation criteria (low mobility), BFD / RLM relaxation will be implemented. Similarly, for Radio Link Failure (RLF) and Radio Resource Management (RRM), RLF measurement relaxation or RRM measurement relaxation will be implemented for users with low mobility or those who are prohibited from accessing the system.

[0046] Low mobility relaxation criteria can be agreed upon through an agreement, distributing the assessment parameters involved in the low mobility relaxation criteria by measuring trigger events. The assessment parameters for low mobility assessment include: T SearchDeltaP and S SearchDeltaP The evaluation parameters for static performance assessment include T. SearchDeltaP 'and S SearchDeltaP '. Among them, S SearchDeltaP and S SearchDeltaP They can be the same or different. The metric for judging low mobility assessment and stationary assessment is the L3 (Layer 3) - RSRP (Reference signal received power) of the reference signal.

[0047] In Release 16, RRM measurement relaxation was introduced for non-connected terminal devices, one of the rules being the low mobility rule.

[0048] Low mobility assessment: within a certain time period (T) SearchDeltaP If the difference between the reference signal reception quality and the UE's current RSRP is less than a certain preset threshold (S... SearchDeltaPIf the signal change is small, the UE can be considered to be stationary or in a low-mobility state. It is important to note that this decision is only considered when the quality of the reference signal reception deteriorates. The specific decision condition is: (S rxlevRef -S rxlev ) SearchDeltaP Among them, S rxlev =S of the current serving cell rxlev The unit is dB; S rxlevRef =S of the current serving cell rxlev Reference value (baseline value), in dB.

[0049] In related technologies, the reference value is set in the following manner:

[0050] (1) The UE selected or reselected a new cell;

[0051] (2)(S rxlev -S rxlevRef >0);

[0052] (3) In T SearchDeltaP The aforementioned conditions for judgment were not met.

[0053] When any of the above conditions are met, the UE will S rxlevRef Set as S of the current serving cell rxlev .

[0054] Please refer to Figure 4 It illustrates a flowchart of a relaxation measurement method provided in one embodiment of this application, which can be applied to... Figure 1 In the terminal device of the system architecture shown, the method includes the following steps.

[0055] Step 210: In the RRC connected state, set the reference value to the current measurement value. The reference value is used for low mobility assessment and / or stationary assessment. The current measurement value includes the signal strength of the measured reference signal.

[0056] When the terminal device is in RRC connected state, it sets the signal strength of the currently measured reference signal as the benchmark value for low mobility assessment or stationary assessment. Of course, the benchmark value can also be set under other conditions. Similar to the disconnected state, for example, if the current measured value is greater than the benchmark value; or if the above-mentioned decision conditions are not met within a limited time, the terminal device will also set the signal strength of the currently measured reference signal (i.e., the current measured value) as the benchmark value for low mobility assessment or stationary assessment.

[0057] ​In RRC connected state, a first reference value is set as the current measurement value; this first reference value is used for low mobility assessment. In RRC connected state, a second reference value is set as the current measurement value; this second reference value is used for stationarity assessment. For example, the first and second reference values ​​are the same. Alternatively, the first and second reference values ​​are different.

[0058] The current measurement value refers to the signal strength of the reference signal most recently measured by the terminal device.

[0059] Signal strength includes at least one of Lay3-RSRP, Lay3-RSRQ (Reference Signal Received Quality), and SINR (Signal to Interference plus Noise Ratio). For RSRP, the unit is dBm; for RSRQ and RS-SINR, the unit is dB (is expressed in dBm in case of RSRP, or in dB in case of RSRQ and RS-SINR).

[0060] The baseline value is used for low mobility assessment or stationary assessment. The terminal device calculates the difference between the measured reference signal strength and the baseline value, and compares the difference with a preset threshold value to determine whether the terminal device is in a low mobility state or a stationary state.

[0061] In summary, the method provided in this embodiment sets the signal strength of the currently measured reference signal as a baseline value for a terminal device in RRC connected state, so that the terminal device can use this baseline value for low mobility assessment / stationary assessment. This provides a method for setting a baseline value for low mobility assessment / stationary assessment when the terminal device is in RRC connected state.

[0062] Please refer to Figure 5 The diagram illustrates a flowchart of a measurement relaxation method provided in one embodiment of this application. This method can be applied to a source access network device, for example, the source access network device may be... Figure 1 The network device with the system architecture shown. The method includes the following steps.

[0063] Step 310: When the terminal device is in RRC connected state, send an RRC dedicated signaling message to the terminal device. The RRC dedicated signaling message is used to trigger the terminal device to set the reference value as the current measurement value. The reference value is used for low mobility assessment and / or stationary assessment. The current measurement value includes the signal strength of the measured reference signal.

[0064] The source access network device is the access network device that the terminal device is currently connected to.

[0065] When the terminal device is in RRC connected state, the source access network device sends an RRC dedicated signaling message to the terminal device to trigger the terminal device to set the reference value to the current measured value. That is, the current measured value is used as the reference value.

[0066] In summary, the method provided in this embodiment sets the signal strength of the currently measured reference signal as a baseline value for a terminal device in RRC connected state, so that the terminal device can use this baseline value for low mobility assessment / stationary assessment. This provides a method for setting a baseline value for low mobility assessment / stationary assessment when the terminal device is in RRC connected state.

[0067] An exemplary embodiment of setting a baseline value for low mobility assessment is provided.

[0068] Please refer to Figure 6 It illustrates a flowchart of a relaxation measurement method provided in one embodiment of this application, which can be applied to... Figure 1 In the terminal device of the system architecture shown, the method includes the following steps.

[0069] Step 211: Upon receiving an RRC dedicated signaling message, set the baseline value to the current measurement value. The baseline value is used for low mobility assessment. The RRC dedicated signaling message includes the first assessment parameter for low mobility assessment.

[0070] For example, the source access network device sends an RRC dedicated signaling message to the terminal device. Upon receiving the RRC dedicated signaling message, the terminal device sets the reference value to the current measurement value.

[0071] The RRC-specific signaling message includes at least one of the following: a first assessment parameter for low mobility assessment, a second assessment parameter for stationarity assessment, and other configurations.

[0072] The first evaluation parameter includes a first preset threshold value S for low mobility evaluation. SearchDeltaP And the first duration T SearchDeltaP At least one of the following. If the first difference is less than a first preset threshold value within a first time period, the terminal device is determined to be in a low mobility state, wherein the first difference is the difference between the signal strength of the measured reference signal and the reference value (first reference value).

[0073] That is, the RRC dedicated signaling message also includes other configurations, which are used to notify the terminal device to report UAI (UE Assistance Information) for low mobility assessment.

[0074] If the RRC dedicated signaling message includes other configurations, the terminal device sends a Low Mobility Assessment (UAI) to the source access network device. The source access network device receives the Low Mobility Assessment (UAI) sent by the terminal device.

[0075] For example, an RRC-specific signaling message can be an RRC connection reconfiguration message or an RRC connection recovery message.

[0076] 1. RRC dedicated signaling messages are RRC connection reconfiguration messages.

[0077] (1) RRC connection reconfiguration message indicates low mobility assessment for at least one of RRM measurement relaxation assessment, RLM measurement relaxation assessment, and BFD measurement relaxation assessment.

[0078] RLM can also be called RLF.

[0079] (2) For example, the RRC connection reconfiguration message includes a handover indication, which is used to instruct the terminal device to hand over from the source access network device to the target access network device; or, the RRC connection reconfiguration message does not include a handover indication.

[0080] That is, in scenarios where the terminal device switches access network devices or does not switch access network devices, the terminal device can set the reference value to the current measurement value when it receives the RRC connection reconfiguration message.

[0081] For example, the RRC connection reconfiguration message can also carry "reconfiguration with sync". Synchronous reconfiguration instructs the terminal device to initiate random access when switching access network devices / switching secondary nodes / adding secondary nodes / modifying secondary nodes. In other words, it instructs the terminal device to perform low mobility assessment when switching access network devices / switching secondary nodes / adding secondary nodes / modifying secondary nodes.

[0082] For example, the RRC connection reconfiguration message may also omit "reconfiguration with sync". That is, it only configures low mobility assessment for the terminal within the same cell.

[0083] (3) For example, the RRC connection reconfiguration message includes a secondary node add / change / modify instruction, the secondary node add instruction being used to instruct the terminal device to add a secondary node; or, the RRC connection reconfiguration message includes a secondary node change instruction, the secondary node change instruction being used to instruct the terminal device to switch the secondary node; or the RRC connection reconfiguration message includes a secondary node modification instruction, the secondary node modification instruction being used to instruct the terminal device to modify the secondary node.

[0084] In other words, the RRC connection reconfiguration message is used to notify the terminal device to perform Add / change / modification of the SN (Secondary Node).

[0085] (4) The terminal device can also send capability information to the source access network device. The capability information is used to indicate that the terminal device supports at least one of RRM measurement relaxation, RLM measurement relaxation and BFD measurement relaxation.

[0086] The source access network device can forward the capability information of the terminal device to other access network devices (e.g., forward capability information to the target access network device). The target access network device is the access network device that the terminal device wants to switch to.

[0087] a. The base station can transfer the terminal device's capability information to other base stations in the handover request. That is, the source access network device sends a handover request to the target access network device. The handover request includes capability information and is used to request the terminal device to be handed over from the source access network device to the target access network device.

[0088] b. The base station can transfer the capability information of the terminal device to other base stations, which can be transmitted in the SN add / modification request. That is, the source access network device sends a secondary node add or modify request to the target access network device. The secondary node add request includes capability information. The secondary node add request is used to request the addition of a secondary node for the terminal device, and the secondary node modify request is used to request the modification of a secondary node for the terminal device.

[0089] Alternatively, the source access network device sends a secondary node handover request to the target access network device. The secondary node handover request includes the capability information of the terminal device and is used to request the handover of the secondary node for the terminal device.

[0090] The handover request also includes measurement relaxation parameters; alternatively, the secondary node add request also includes measurement relaxation parameters; alternatively, the secondary node modify request also includes measurement relaxation parameters; alternatively, the secondary node handover request also includes measurement relaxation parameters. Measurement relaxation parameters are used as a configuration reference for the target access network device / target cell.

[0091] Measurement relaxation parameters are configured by the source access network equipment for the terminal equipment. Measurement relaxation parameters include at least one of the following measurement relaxation parameters: RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation.

[0092] The measurement relaxation parameters include at least one of a first assessment parameter for low mobility assessment and a first enable or disable indication, wherein the first enable or disable indication is used to indicate whether the low mobility assessment is enabled or disabled.

[0093] That is, the relaxation measurement parameters may include at least one relaxation measurement parameter corresponding to relaxation measurement. For example, the relaxation measurement parameters corresponding to different relaxation measurements may be the same or different. For instance, the first assessment parameter of RRM relaxation measurement and the first assessment parameter of RLM relaxation measurement may be the same or different.

[0094] For example, the base station carries measurement relaxation parameters for RRM / RLM / BFD measurement relaxation in the RRC connection reconfiguration message. If the terminal device receives the RRC connection reconfiguration message, it sets the reference value to the current measurement value when handing over to the target base station / target cell, or when accessing a new Pscell, for low mobility assessment. At this point, the handover or access to the new Pscell is successful. For the terminal, it can determine whether the Medium Access Control (MAC) random access procedure is complete. Here, Pcell handover to the target cell / target access network device; Pscell handover is equivalent to SN change. If the terminal does not receive the RRC connection reconfiguration message, or the handover or access to the new Pscell fails, low mobility assessment does not need to be initiated.

[0095] As one example: The terminal determines that the master node handover is successful: that is, the MAC node of the MCG successfully completes the random access procedure to the target cell or base station. At this time, the spCellConfig of the MCG in the RRC reconfiguration message carries the synchronization reconfiguration, and the terminal will initiate a random access procedure after receiving the synchronization reconfiguration instruction. That is, after the MAC of an MCG successfully completes a random access procedure after applying an reconfigurationWithSync in spCellConfig of an MCG, the terminal sets the reference value to the current measurement value.

[0096] That is, when the terminal device receives an RRC connection reconfiguration message and switches from the source access network device to the target access network device, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and switches to the target primary cell, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and switches to the first target primary / secondary cell, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and accesses the second target primary / secondary cell, it sets the reference value to the current measurement value.

[0097] Optionally, when receiving an RRC connection reconfiguration message and accessing the second target primary / secondary cell, setting the reference value to the current measurement value includes: when receiving an RRC connection reconfiguration message and modifying the second target primary / secondary cell, setting the reference value to the current measurement value.

[0098] As one example: The terminal determines that the handover to the first target primary / secondary cell was successful: that is, the MAC node of the SCG successfully completed the random access procedure to the target cell or base station. At this time, the spCellConfig of the SCG in the RRC reconfiguration message carries the synchronization reconfiguration, and the terminal will initiate a random access procedure after receiving the synchronization reconfiguration instruction. That is, after the MAC of an SCG successfully completes a Random Access procedure after applying an reconfigurationWithSync in spCellConfig of an SCG, the terminal sets the reference value to the current measurement value.

[0099] If low mobility assessment and / or stationary assessment are disabled on the terminal device, the source access network device does not send an RRC connection reconfiguration message. If no RRC connection reconfiguration message is received, the terminal device disables low mobility assessment.

[0100] 2. RRC dedicated signaling messages are RRC connection recovery messages.

[0101] The RRC connection restoration message indicates that the low mobility assessment can be used for at least one of the RRM measurement relaxation assessment, RLM measurement relaxation assessment, and BFD measurement relaxation assessment. That is, the RRC connection restoration message is used to notify the terminal device that the low mobility assessment can be used for at least one of the RRM measurement relaxation assessment, RLM measurement relaxation assessment, and BFD measurement relaxation assessment.

[0102] In summary, the method provided in this embodiment, for a terminal device in RRC connected state, allows the terminal device to set the signal strength of the currently measured reference signal as a baseline value upon receiving an RRC dedicated signaling message, so that the terminal device can use this baseline value for low mobility assessment. Alternatively, the terminal device can set the signal strength of the currently measured reference signal as a baseline value upon receiving an RRC connection reconfiguration message and switching to the target base station / target cell / target secondary node. This provides a method for setting a baseline value for low mobility assessment when the terminal device is in RRC connected state.

[0103] An exemplary embodiment of setting a benchmark value for staticity assessment is provided.

[0104] Please refer to Figure 7 It illustrates a flowchart of a relaxation measurement method provided in one embodiment of this application, which can be applied to... Figure 1 In the terminal device of the system architecture shown, the method includes the following steps.

[0105] Step 212: Upon receiving an RRC dedicated signaling message, set the baseline value to the current measurement value. The baseline value is used for static assessment. The RRC dedicated signaling message includes a second assessment parameter for static assessment.

[0106] The second evaluation parameter includes the second preset threshold value S. SearchDeltaP 'and second duration T SearchDeltaP At least one of the following. The second preset threshold value may be the same as or different from the first preset threshold value. The first duration and the second duration may be the same as or different. Within the second duration, if the second difference is less than the second preset threshold value, the terminal device is determined to be in a static state, wherein the second difference is the difference between the measured signal strength of the reference signal and the reference value (second reference value).

[0107] Upon receiving an RRC dedicated signaling message, the terminal device can synchronously set the second reference value to the current measurement value. The second reference value is used for static assessment.

[0108] The RRC-specific signaling message includes at least one of the following: a first assessment parameter for low mobility assessment, a second assessment parameter for stationarity assessment, and other configurations.

[0109] That is, the RRC dedicated signaling message also includes other configurations, which are used to notify the terminal device to report UAI (UE AssistantInfo) for static assessment.

[0110] If the RRC dedicated signaling message includes other configurations, the terminal device sends a static assessment UAI to the source access network device. The source access network device receives the static assessment UAI sent by the terminal device.

[0111] For example, an RRC-specific signaling message can be an RRC connection reconfiguration message or an RRC connection recovery message.

[0112] 1. RRC dedicated signaling messages are RRC connection reconfiguration messages.

[0113] (1) RRC connection reconfiguration message indicates static assessment for at least one of RRM measurement relaxation assessment, RLM measurement relaxation assessment, and BFD measurement relaxation assessment.

[0114] (2) For example, the RRC connection reconfiguration message includes a handover indication, which is used to instruct the terminal device to hand over from the source access network device to the target access network device; or, the RRC connection reconfiguration message does not include a handover indication.

[0115] For example, the RRC connection reconfiguration message can also carry "reconfiguration with sync". Synchronous reconfiguration instructs the terminal device to initiate random access when switching access network devices / switching secondary nodes / adding secondary nodes / modifying secondary nodes. In other words, it instructs the terminal device to perform a static evaluation of its configuration when switching access network devices / switching secondary nodes / adding secondary nodes / modifying secondary nodes.

[0116] For example, the RRC connection reconfiguration message may also omit "reconfiguration with sync". That is, the terminal configuration is only evaluated statically within the cell.

[0117] (3) For example, the RRC connection reconfiguration message includes a secondary node add / change / modify instruction, the secondary node add instruction being used to instruct the terminal device to add a secondary node; or, the RRC connection reconfiguration message includes a secondary node change instruction, the secondary node change instruction being used to instruct the terminal device to switch the secondary node; or, the RRC connection reconfiguration message includes a secondary node modification instruction, the secondary node modification instruction being used to instruct the terminal device to modify the secondary node.

[0118] (4) The terminal device can also send capability information to the source access network device. The capability information is used to indicate that the terminal device supports at least one of RRM measurement relaxation, RLM measurement relaxation and BFD measurement relaxation.

[0119] The source access network device can forward the capability information of the terminal device to other access network devices (e.g., forward capability information to the target access network device). The target access network device is the access network device that the terminal device wants to switch to.

[0120] a. The base station can forward the capability information of the terminal device to other base stations, which can be transmitted in the handover request. That is, the source access network device sends a handover request to the target access network device. The handover request includes capability information and is used to request the terminal device to be handed over from the source access network device to the target access network device.

[0121] b. The base station can forward the capability information of the terminal device to other base stations, which can be transmitted in the SN add / modification request. That is, the source access network device sends a secondary node add or modify request to the target access network device. The secondary node add request or secondary node modify request includes capability information. The secondary node add request is used to request the addition of a secondary node for the terminal device, and the secondary node modify request is used to request the modification of a secondary node for the terminal device.

[0122] Alternatively, the source access network device sends a secondary node handover request to the target access network device. The secondary node handover request includes the capability information of the terminal device and is used to request the handover of the secondary node for the terminal device.

[0123] The handover request also includes measurement relaxation parameters; alternatively, the secondary node add request also includes measurement relaxation parameters; alternatively, the secondary node modify request also includes measurement relaxation parameters; alternatively, the secondary node handover request also includes measurement relaxation parameters. Measurement relaxation parameters are used as a configuration reference for the target access network device / target cell.

[0124] Measurement relaxation parameters are configured by the source access network equipment for the terminal equipment. Measurement relaxation parameters include at least one of the following measurement relaxation parameters: RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation.

[0125] The measured relaxation parameters include at least one of a first assessment parameter for low mobility assessment, a second assessment parameter for static assessment, a first enable or disable indication, and a second enable or disable indication. The first enable or disable indication is used to indicate whether to enable or disable the low mobility assessment, and the second enable or disable indication is used to indicate whether to enable or disable the static assessment.

[0126] That is, the relaxation measurement parameters may include at least one relaxation measurement parameter corresponding to relaxation measurement. For example, the relaxation measurement parameters corresponding to different relaxation measurements may be the same or different. For instance, the first assessment parameter of RRM relaxation measurement and the first assessment parameter of RLM relaxation measurement may be the same or different.

[0127] For example, the base station carries measurement relaxation parameters for RRM / RLM / BFD measurement relaxation in the RRC connection reconfiguration message. If the terminal device receives the RRC connection reconfiguration message, it sets the reference value to the current measurement value when handing over to the target base station / target cell, or when accessing a new Pscell, for low mobility assessment. At this point, the handover or access to the new Pscell is successful. For the terminal, it can determine whether the Medium Access Control (MAC) random access procedure is complete. Here, Pcell handover to the target cell / target access network device; Pscell handover is equivalent to SN change. If the terminal does not receive the RRC connection reconfiguration message, or the handover or access to the new Pscell fails, low mobility assessment does not need to be initiated.

[0128] As one example: The terminal determines that the master node handover is successful, meaning that the MCG's MAC node has successfully completed the random access procedure to the target cell or base station. At this time, the spCellConfig of the MCG in the RRC reconfiguration message carries the synchronization reconfiguration, and the terminal will initiate a random access procedure after receiving the synchronization reconfiguration instruction. That is, after the MAC of an MCG successfully completes a Random Access procedure after applying an reconfigurationWithSync in spCellConfig of an MCG, the terminal sets the reference value to the current measurement value.

[0129] That is, when the terminal device receives an RRC connection reconfiguration message and switches from the source access network device to the target access network device, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and switches to the target primary cell, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and switches to the first target primary / secondary cell, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and accesses the second target primary / secondary cell, it sets the reference value to the current measurement value.

[0130] Optionally, when receiving an RRC connection reconfiguration message and accessing the second target primary / secondary cell, setting the reference value to the current measurement value includes: when receiving an RRC connection reconfiguration message and modifying the second target primary / secondary cell, setting the reference value to the current measurement value.

[0131] As one example: The terminal determines that the handover to the first target primary / secondary cell was successful: that is, the MAC node of the SCG successfully completed the random access procedure to the target cell or base station. At this time, the spCellConfig of the SCG in the RRC reconfiguration message carries the synchronization reconfiguration, and the terminal will initiate a random access procedure after receiving the synchronization reconfiguration instruction. That is, after the MAC of an SCG successfully completes a Random Access procedure after applying an reconfigurationWithSync in spCellConfig of an SCG, the terminal sets the reference value to the current measurement value.

[0132] When the static assessment of the terminal device is disabled, the source access network device does not send an RRC connection reconfiguration message. If no RRC connection reconfiguration message is received, the terminal device disables static assessment.

[0133] 2. RRC dedicated signaling messages are RRC connection recovery messages.

[0134] The RRC connection restoration message indicates that the quiescent assessment can be used for at least one of the RRM measurement relaxation assessment, RLM measurement relaxation assessment, and BFD measurement relaxation assessment. That is, the RRC connection restoration message is used to notify the terminal device that the quiescent assessment can be used for at least one of the RRM measurement relaxation assessment, RLM measurement relaxation assessment, and BFD measurement relaxation assessment.

[0135] In summary, the method provided in this embodiment, for a terminal device in RRC connected state, allows the terminal device to set the signal strength of the currently measured reference signal as a reference value upon receiving an RRC dedicated signaling message, so that the terminal device can use this reference value for static performance evaluation. Alternatively, the terminal device can set the signal strength of the currently measured reference signal as a reference value upon receiving an RRC connection reconfiguration message and switching to the target base station / target cell / target secondary node. This provides a method for setting a reference value for static performance evaluation when the terminal device is in RRC connected state.

[0136] An exemplary embodiment is provided in which a source access network device forwards terminal device capability information to other access network devices.

[0137] Please refer to Figure 8 The diagram illustrates a flowchart of a measurement relaxation method provided in one embodiment of this application. This method can be applied to a source access network device, for example, the source access network device may be... Figure 1 The network device with the system architecture shown. The method includes the following steps.

[0138] Step 301: Receive capability information sent by the terminal device. The capability information is used to indicate that the terminal device supports at least one of RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation.

[0139] For example, RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation each correspond to an indication message, which indicates whether the terminal device supports such measurement relaxation. The capability information may include at least one of these three indication messages. For example, 0 indicates no support, and 1 indicates support. The capability information may include: a first indication message corresponding to RRM measurement relaxation (1), a second indication message corresponding to RLM measurement relaxation (0), and a third indication message corresponding to BFD measurement relaxation (1). This capability information indicates that the terminal device supports RRM and BFD measurement relaxation, but does not support RLM measurement relaxation.

[0140] For example, RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation can also correspond to an indication message, that is, an indication message describing whether the terminal device indicates these three measurement relaxations. For example, 0 indicates not supported, and 1 indicates supported. The capability information may include the indication message: 101. This capability information indicates that the terminal device supports RRM measurement relaxation and BFD measurement relaxation, but does not support RLM measurement relaxation.

[0141] Step 302: Forward capability information to the target access network device.

[0142] For example, after receiving capability information from a terminal device, the source access network device can forward that capability information to other access network devices, such as the target access network device.

[0143] The target access network device can be the access network device that the terminal device wants to switch to. For example, the target access network device is the access network device corresponding to the Pcell that the terminal device wants to switch to.

[0144] The target access network device can be the access network device corresponding to the primary / secondary cell (secondary node) that the terminal device wants to switch / add / modify.

[0145] For example, the source access network device sends a handover request to the target access network device. The handover request includes capability information and is used to request the terminal device to be switched from the source access network device to the target access network device.

[0146] The source access network device sends a secondary node add request to the target access network device. The secondary node add request includes capability information and is used to request the addition of a secondary node for the terminal device.

[0147] The source access network device sends a secondary node modification request to the target access network device. The secondary node modification request includes capability information and is used to request modification of the secondary node for the terminal device. For example, the secondary node modification request is used to request modification of relevant information (e.g., configuration information) of the secondary node currently accessed by the terminal device.

[0148] The source access network device sends a secondary node handover request to the target access network device. The secondary node handover request includes the terminal device's capability information and is used to request a handover of the secondary node for the terminal device.

[0149] The handover request also includes measurement relaxation parameters; alternatively, the secondary node add request also includes measurement relaxation parameters; alternatively, the secondary node modify request also includes measurement relaxation parameters; alternatively, the secondary node handover request also includes measurement relaxation parameters. Measurement relaxation parameters are used as a configuration reference for the target access network device / target cell.

[0150] Measurement relaxation parameters are configured by the source access network equipment for the terminal equipment. Measurement relaxation parameters include at least one of the following measurement relaxation parameters: RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation.

[0151] For example, RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation can each correspond to a set of measurement relaxation parameters, or RRM measurement relaxation, RLM measurement relaxation, and BFD measurement relaxation can correspond to the same set of measurement relaxation parameters.

[0152] For example, a set of relaxation measurement parameters may include at least one of a first assessment parameter for low mobility assessment, a second assessment parameter for restlessness assessment, a first enable or disable indication, and a second enable or disable indication. The first enable or disable indication is used to indicate whether the low mobility assessment is enabled or disabled. The second enable or disable indication is used to indicate whether the restlessness assessment is enabled or disabled.

[0153] Step 303: Do not send an RRC connection reconfiguration message if the low mobility assessment and / or stationary assessment of the terminal device are disabled.

[0154] For example, when low mobility assessment and / or stationary assessment of terminal devices are disabled, the source access network device does not send an RRC connection reconfiguration message carrying measurement relaxation parameters.

[0155] For example, if the source access network device determines that the terminal does not support RRM / RLM / BFD measurement relaxation, it disables the low mobility assessment and / or stationary assessment of the terminal device. Alternatively, if the source access network device determines that the target access network device does not support RRM / RLM / BFD measurement relaxation, it disables the low mobility assessment and / or stationary assessment of the terminal device. Or, the source access network device determines, based on other information, that the low mobility assessment and / or stationary assessment of the terminal device is currently not enabled.

[0156] If the terminal device does not receive an RRC connection reconfiguration message carrying measurement relaxation parameters, it will not enable low mobility assessment and / or stationary assessment.

[0157] Step 304: When the terminal device is in RRC connection state, send an RRC connection reconfiguration message to the terminal device. The RRC connection reconfiguration message is used to trigger the terminal device to set the reference value to the current measurement value.

[0158] For example, if the source access network device needs to enable low mobility assessment and / or stationary assessment of the terminal device, it sends an RRC connection reconfiguration message to the terminal device, which carries measurement relaxation parameters. After receiving the RRC connection reconfiguration message, the terminal sets the reference value to the current measurement value.

[0159] The base station carries measurement relaxation parameters for RRM / RLM / BFD measurement relaxation in the RRC connection reconfiguration message. If the terminal device receives the RRC connection reconfiguration message, it sets the baseline value to the current measurement value when handing over to the target base station / target cell, or when accessing a new Pscell, for low mobility assessment. This indicates a successful handover or successful access to the new Pscell. For the terminal, it can determine whether the Medium Access Control (MAC) random access procedure is complete. Here, Pcell handover to the target cell / target access network device; Pscell handover is also known as SNchange. If the terminal does not receive the RRC connection reconfiguration message, or the handover or access to a new Pscell fails, low mobility assessment does not need to be initiated.

[0160] As one example: The terminal determines that the master node handover is successful: that is, the MAC node of the MCG successfully completes the random access procedure to the target cell or base station. At this time, the spCellConfig of the MCG in the RRC reconfiguration message carries the synchronization reconfiguration, and the terminal will initiate a random access procedure after receiving the synchronization reconfiguration instruction. That is, after the MAC of an MCG successfully completes a random access procedure after applying an reconfigurationWithSync in spCellConfig of an MCG, the terminal sets the reference value to the current measurement value.

[0161] That is, when the terminal device receives an RRC connection reconfiguration message and switches from the source access network device to the target access network device, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and switches to the target primary cell, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and switches to the first target primary / secondary cell, it sets the reference value to the current measurement value; or, when it receives an RRC connection reconfiguration message and accesses the second target primary / secondary cell, it sets the reference value to the current measurement value.

[0162] Optionally, when receiving an RRC connection reconfiguration message and accessing the second target primary / secondary cell, setting the reference value to the current measurement value includes: when receiving an RRC connection reconfiguration message and modifying the second target primary / secondary cell, setting the reference value to the current measurement value.

[0163] As one example: The terminal determines that the handover to the first target primary / secondary cell was successful: that is, the MAC node of the SCG successfully completed the random access procedure to the target cell or base station. At this time, the spCellConfig of the SCG in the RRC reconfiguration message carries the synchronization reconfiguration, and the terminal will initiate a random access procedure after receiving the synchronization reconfiguration instruction. That is, after the MAC of an SCG successfully completes a Random Access procedure after applying an reconfigurationWithSync in spCellConfig of an SCG, the terminal sets the reference value to the current measurement value.

[0164] In summary, the method provided in this embodiment allows a terminal device to report capability information, such as whether it supports measurement relaxation, to a source access network device. The source access network device can then forward this capability information to other access network devices for configuration reference. The source access network device can carry measurement evaluation parameters in the RRC connection reconfiguration message. When the terminal device receives this RRC connection reconfiguration message and completes cell handover, it sets the baseline value to the current measurement value. If the terminal device does not receive this RRC connection reconfiguration message, low mobility assessment and stationary assessment are not enabled.

[0165] It should be noted that the low mobility assessment and stationary assessment are described as two separate embodiments in the above embodiments. However, those skilled in the art can combine the two embodiments to achieve a new embodiment that simultaneously supports low mobility assessment and / or stationary assessment, which will not be elaborated further.
