Description

[0001] This application is a divisional application of Chinese patent application No. 202080102179.5, entitled "A Cell Measurement Indication Method, Terminal Equipment and Network Equipment", which entered the Chinese national phase of PCT international patent application PCT / CN2020 / 106665, filed on August 3, 2020. Technical Field

[0002] This invention relates to the field of communication technology, and in particular to a cell measurement indication method, terminal equipment, and network equipment. Background Technology

[0003] For terminal devices, regardless of whether they are in connected or idle state, in order to obtain the preferred serving cell, the terminal device needs to measure all the surrounding neighboring cells, including cells with the same frequency, cells with different frequencies, and cells with different systems. When there are many frequency points to measure, cell measurement will cause the terminal device to consume a lot of power.

[0004] To address this issue, the 5G protocol introduces the concept of relaxed measurement. Relaxed measurement can reduce the frequency points used by terminal devices during cell measurements, shorten measurement time, or extend the measurement cycle of periodic measurements, thereby saving power consumption of terminal devices. Current 5G protocols involve relaxed measurement schemes for terminal devices in connectionless states. In connectionless states, the relaxed measurement behavior is determined by the terminal device itself, and the network device cannot know the status of the terminal device, thus failing to provide network-controllable cell measurements. Summary of the Invention

[0005] This invention provides a cell measurement indication method, a terminal device, and a network device, which can solve the problem of how to provide a cell measurement scheme that is controllable by the network device.

[0006] Firstly, a method for indicating cell measurement is provided, including:

[0007] Evaluation parameters for low-speed movement criteria sent by network devices;

[0008] The mobility status of the terminal device is assessed based on the evaluation parameters and the measurement results of the serving cell.

[0009] The network device reports the mobility status of the terminal device, which is used as a reference for the network device to instruct the terminal device to perform cell measurements.

[0010] Secondly, a method for indicating cell measurement is provided, including:

[0011] Send the evaluation parameters of the low-speed movement criterion to the terminal device;

[0012] The network receives the mobile status of the terminal device reported by the terminal device. The mobile status of the terminal device is evaluated based on the evaluation parameters and the measurement results of the serving cell. The mobile status of the terminal device is used as a reference for the network device to instruct the terminal device to perform cell measurement.

[0013] The cell measurement indication method provided in this embodiment of the invention allows a network device to send low-speed mobility target assessment parameters to a terminal device. The terminal device can then assess its own mobility status based on these parameters and the measurement results of the serving cell, and report its mobility status to the network device. This enables the network device to determine the cell measurement status (including normal measurement and / or relaxed measurement). Thus, the network device can obtain information about the terminal device's mobility status and, by referring to this status, determine the cell measurement status and instruct the terminal device to perform cell measurement (normal measurement and / or relaxed measurement). This provides a network device-controllable cell measurement scheme.

[0015] The receiving module is used to receive evaluation parameters of the low-speed mobility criteria sent by the network device;

[0016] The processing module is used to assess the mobility status of the terminal device based on the evaluation parameters and the measurement results of the serving cell.

[0017] The sending module is used to report the mobility status of the terminal device to the network device so that the network device can determine the cell measurement status.

[0018] Fourthly, a network device is provided, comprising:

[0019] The sending module is used to send the evaluation parameters of the low-speed movement criterion to the terminal device;

[0020] The receiving module is used to receive the movement status of the terminal device reported by the terminal device in order to determine the cell measurement status. The movement status of the terminal device is evaluated based on the evaluation parameters and the measurement results of the serving cell.

[0033] The technical solutions of the embodiments of the present invention will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] In embodiments of the present invention, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in embodiments of the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The symbol " / " in this article indicates that the related objects are in an "or" relationship; for example, A / B means A or B.

[0036] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0037] The technical solution provided by this invention can be applied to various communication systems, such as 5G communication systems, future evolution systems, or multiple communication convergence systems. It can include various application scenarios, such as machine-to-machine (M2M), data-to-machine (D2M), macro-micro communication, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (uRLLC), and massive machine-type communication (mMTC). For example, embodiments of this invention can be applied to cell measurement of connected terminal devices in a 5G communication system.

[0038] The main application scenarios of 5G at present are: enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine-type communication (mMTC).

[0039] In related technologies, the New Radio (NR) can be deployed independently. In 5G network environments, to reduce air interface signaling, quickly restore wireless connections, and rapidly resume data services, a new Radio Resource Control (RRC) state is defined: the RRC_inactive state. This state differs from the RRC_idle and RRC_connected states. The three RRC states in a 5G network environment are explained below.

[0040] RRC_idle: Mobility is based on cell reselection of terminal equipment. Paging is initiated by the core network, the paging area is configured by the core network, there is no user equipment (UE) access layer (AS) context on the base station side, and there is no RRC connection.

[0041] RRC_connected: An RRC connection exists. The base station and UE have a UE AS context. The network side knows the UE's location at the cell level. Mobility is controlled by the network side. Unicast data can be transmitted between the UE and the base station.

[0042] RRC_inactive: Mobility is based on UE cell selection reselection, there is a connection between CN and NR, the UE AS context exists on a certain base station, paging is triggered by the (Radio Access Network) RAN, the RAN-based paging area is managed by the RAN, and the network side knows the UE's location at the RAN-based paging area level.

[0043] For terminal devices, regardless of whether they are in connected or disconnected mode, in order to obtain the preferred serving cell, the terminal device needs to measure all the surrounding neighboring cells, including cells with the same frequency, cells with different frequencies, and cells with different systems. When there are many frequency points to be measured, cell measurement will cause the terminal device to consume a lot of power.

[0044] Especially for the lightweight terminals (NR-light) introduced in R17 NR, these devices are generally small in size and have limited battery capacity, thus requiring reduced power consumption. Currently, NR-light mainly includes the following three types:

[0045] (1) Industrial Wireless Sensors: Compared with devices in URLLC scenarios, industrial wireless sensors have relatively low latency and reliability requirements, and the cost and power consumption of these devices are also lower than those of URLLC and eMBB.

[0046] (2) Video surveillance is mainly used in smart cities, industrial factories, and other video monitoring applications. Specifically, it can be applied to the collection and processing of data in smart cities to enable more effective monitoring and control of urban resources and to provide more effective services to urban residents.

[0047] (3) Wearable devices, including smartwatches, electronic health devices, and some medical monitoring devices. A common feature of these devices is their small size.

[0048] To address the issue of high power consumption of terminal devices during cell measurements, the 5G protocol introduces relaxed measurement, which can reduce the frequency of cell measurements, shorten the measurement time, or extend the measurement cycle of periodic measurements, thereby saving power consumption of terminal devices.

[0049] Specifically, in the related technologies, two sets of judgment criteria for radio resource management (RRM) relaxation measurement were introduced in the R16 terminal energy saving project: the "UE is not located at the cell edge" criterion and the "low-mobility" criterion. Both of these criteria are based on the "cell-level" measurement results of the UE in the serving cell.

[0050] 1. Criterion: "UE is not located at the cell edge"

[0051] To meet this criterion, network devices will configure a reference signal receiving power (RSRP) threshold and an RSRQ threshold. When the RSRP of the UE in the serving cell is greater than the RSRP threshold, and the RSRQ of the UE in the serving cell is greater than the RSRQ threshold when the network device is configured with an RSRQ threshold, then the UE is considered to meet the "UE is not located at the cell edge" criterion.

[0052] The RSRP threshold configured on the network device for the "UE is not located at the cell edge" criterion must be less than the RSRP intra-frequency measurement threshold (SIntraSearchP) and the RSRP inter-frequency measurement threshold (SnonIntraSearchP). If the network device also configures an RSRQ threshold for the "UE is not located at the cell edge" criterion, then the RSRQ threshold used for the "UE is not located at the cell edge" criterion must be less than the RSRQ intra-frequency measurement threshold (SIntraSearchQ) and the RSRQ inter-frequency measurement threshold (SnonIntraSearchQ).

[0053] II. "Low Mobility" Criteria

[0054] According to this guideline, network devices will be configured with the RSRP change assessment duration (TsearchDeltaP) and the RSRP change threshold (S). searchDeltaP When the change in RSRP of the UE on the serving cell is less than S within a certain period of time (TsearchDeltaP), searchDeltaP If the UE meets the "low mobility" criterion, then the UE is considered to meet the criterion.

[0055] After completing cell selection / reselection, the UE needs to perform normal RRM measurements (i.e., normal cell measurements) for at least a certain period of time within TsearchDeltaP.

[0056] The existing 5G protocols utilize the aforementioned guidelines to address the relaxation measurement schemes for terminal devices in the non-connected state. In the non-connected state, the relaxation measurement behavior is generally determined by the terminal device itself. However, the relaxation measurement schemes for the connected state are not discussed. Therefore, how terminal devices perform relaxation measurements in the connected state and how to provide cell measurements that are controllable by network devices are urgent problems to be solved.

[0057] Based on the above problems, the cell measurement indication method provided in this embodiment of the invention allows the network device to send evaluation parameters of the low-speed movement criterion to the terminal device. The terminal device can then evaluate its own movement status based on these evaluation parameters and the measurement results of the serving cell, and report its movement status to the network device. This enables the network device to determine the cell measurement status. Thus, the network device can obtain information about the terminal device's movement status and can use this information to determine the cell measurement status, instructing the terminal device to perform cell measurement (normal measurement, and / or relaxed measurement). This provides a network device-controllable cell measurement scheme.

[0058] The cell measurement indication method provided in this embodiment of the invention can be applied to terminal devices in a connected state.

[0059] The cell measurement indication method provided in this invention can be applied to wireless communication systems. For example,... Figure 1 The diagram shown is a schematic representation of the system architecture of a wireless communication system according to an embodiment of the present invention. Figure 1 The wireless communication system includes terminal equipment and network equipment. In practical applications, the connection between the terminal equipment and the network equipment can be a wireless connection. The cell measurement indication method provided in this embodiment of the invention is applied to... Figure 1 In the wireless communication system shown, Figure 1 Network devices in the middle can send to Figure 1The terminal device sends evaluation parameters for low-speed movement to the network device. Based on these evaluation parameters and the measurement results of the serving cell, the terminal device can evaluate its own movement status and report it to the network device. In this way, the network device can know the movement status of the terminal device and determine the cell measurement status by referring to the movement status of the terminal device, and instruct the terminal device to perform cell measurement (normal measurement, and / or, relaxed measurement). This provides a cell measurement scheme that is controllable by the network device.

[0060] The terminal device in this embodiment of the invention can be referred to as user equipment (UE). This terminal device can be a personal communication service (PCS) phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), etc. It can also be a mobile phone, mobile station (MS), mobile terminal, or laptop computer. This terminal device can communicate with one or more core networks via a radio access network (RAN). For example, the terminal device can be a mobile phone (or "cellular" phone) or a computer with a mobile terminal. It can also be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. The terminal device can also be a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved network. The above is just one example, and it is not limited to this in actual applications.

[0061] The network devices in this embodiment of the invention can be macro base stations (eNBs or e-NodeBs), micro base stations (also known as "small base stations"), pico base stations, access points (APs), transmission points (TPs), or new generation Node Bs (gNodeBs) in LTE systems, NR communication systems, or authorized auxiliary access long-term evolution (LAA-LTE) systems. The aforementioned network devices can also be other types of network devices in future 5G communication systems or future evolved networks.

[0062] The cell measurement indication method provided in this embodiment of the invention can be implemented through the interaction between network devices and terminal devices, which will be described in detail below.

[0063] like Figure 2 As shown, an embodiment of the present invention provides a cell measurement indication method, the method comprising:

[0064] 201. Network devices send evaluation parameters of low-speed movement criteria to terminal devices.

[0065] Correspondingly, the terminal device receives the evaluation parameters of the low-speed mobility criteria sent by the network device.

[0066] The evaluation parameters for the low-speed movement criterion include the following (1) and (2):

[0067] First duration.

[0068] The first duration is the evaluation duration for the change in the received signal strength of the reference signal.

[0078] Optionally, the aforementioned media access control (MAC) signaling can be a MAC control element (CE).

[0079] 202. The terminal device assesses its mobility status based on the assessment parameters and the measurement results of the serving cell.

[0080] Optionally, the measurement results of the serving cell may include the reference signal received signal strength of the serving cell, i.e., the measured value of RSRP and / or the measured value of RSRQ.

[0081] In this embodiment of the invention, the movement state of the terminal device can include both low-speed movement and non-low-speed movement. The movement state of the terminal device obtained from the above evaluation can be either low-speed movement or non-low-speed movement.

[0082] Optionally, the terminal device can determine the relationship between the change in the received reference signal strength of the serving cell within the first time period and the change threshold value of the received reference signal strength, and use this to assess the mobility status of the terminal device.

[0083] Optionally, 102 above can be replaced with 102a below.

[0084] 202a. Evaluate the mobility status of the terminal equipment based on the evaluation parameters of the low-speed mobility criterion, the measurement results of the serving cell, and the conditions of the low-speed mobility criterion.

[0085] Optionally, 102a can be implemented using one of the following two methods:

[0086] The first possible implementation is: if the measurement results continuously meet the entry conditions of the low-speed movement criterion within the first time period, then the movement state of the terminal device is determined to be low-speed movement.

[0087] The second possible implementation is as follows: if the measurement results continuously meet the departure conditions of the low-speed movement criterion within the first time period, then the movement state of the terminal device is determined to be non-low-speed movement.

[0088] Optionally, the conditions for the low-speed movement criterion include at least one of the following (A) and (B):

[0089] (A) Entry conditions for the low-speed movement criterion;

[0090] In this embodiment of the invention, the entry conditions for the low-speed movement criterion include:

[0091] Condition 1: (Srxlev) Ref -Srxlev) searchDeltaP ;

[0092] Among them, Srxlev Ref Srxlev is the reference value for the received signal strength of the reference signal, and Srxlev is the measured value for the received signal strength of the reference signal in the serving cell. searchDeltaP This is the threshold value for the change in the received signal strength of the reference signal.

[0093] Optionally, if a hysteresis parameter is introduced, the entry conditions for the low-speed movement criterion include:

[0094] Condition 2: (Srxlev) Ref -Srxlev+Hyst) searchDeltaP ;

[0095] Hyst is the hysteresis parameter.

[0096] (B) Departure conditions for the low-speed movement criterion.

[0097] In this embodiment of the invention, the departure condition of the low-speed movement criterion includes:

[0098] Condition 3: (Srxlev) Ref -Srxlev)>S searchDeltaP ;

[0099] Among them, Srxlev Ref Srxlev is the reference value for the received signal strength of the reference signal, and Srxlev is the measured value for the received signal strength of the reference signal in the serving cell. searchDeltaP This is the threshold value for the change in the received signal strength of the reference signal.

[0100] Optionally, if a hysteresis parameter is introduced, the entry conditions for the low-speed movement criterion include:

[0101] Condition 4: (Srxlev) Ref -Srxlev-Hyst)>S searchDeltaP ;​​

[0102] Hyst is the hysteresis parameter.

[0103] Optionally, in any of the above conditions 1, 2, 3, or 4, Srxlev Ref The initial value can be the measured value of the current reference signal received signal strength when the terminal device receives the low-speed mobility criterion evaluation parameters sent by the network device.

[0104] Further optional, Srxlev Ref The initial value can be the measured value of the received signal strength of the reference signal detected by the terminal device for the first time after receiving the low-speed motion criterion evaluation parameters sent by the network device.

[0105] Optional, Srxlev Ref It can be updated.

[0106] Srxlev Ref The update includes two methods:

[0107] Method 1: When the entry condition of the low-speed movement criterion is not met, adjust Srxlev... Ref Update to the current measured value of the received reference signal strength;

[0108] Method 2: When the departure condition of the low-speed movement criterion is met, Srxlev... Ref Update to the current reference signal received signal strength measurement.

[0109] Srxlev can be processed using at least one of methods 1 or 2 described above. Ref Update.

[0110] In this embodiment of the invention, when evaluating the movement state of a terminal device, it is considered that if the entry condition of the low-speed movement criterion is met, the movement state of the terminal device is low-speed movement; if the departure condition of the low-speed movement criterion is met, the movement state of the terminal device is non-low-speed movement.

[0111] 203. The terminal device reports its movement status to the network device.

[0112] The mobility status of the terminal device is used to provide a reference for the network device to instruct the terminal device to perform cell measurements.

[0113] Correspondingly, the network device receives the movement status of the terminal device reported by the terminal device.

[0114] Optionally, the network device may refer to the mobile status of the terminal device to determine how to instruct the terminal device to perform cell measurements and generate corresponding measurement commands.

[0115] In this embodiment of the invention, after the terminal device assesses and obtains the mobility status of the terminal device, it can report the mobility status of the terminal device to the network device.

[0116] Optionally, the terminal device may report its mobility status to the network device by actively reporting it after receiving the evaluation parameters of the low-speed mobility criteria sent by the network device.

[0117] Optionally, the terminal device may report its movement status to the network device based on instructions from the network device.

[0118] Optionally, the terminal device can evaluate the low-speed movement criteria based on the measurement results of the serving cell. When the low-speed movement criterion entry condition is met, the terminal device can trigger a reporting process to indicate to the network device that the terminal device meets the low-speed movement criterion. When the low-speed movement criterion departure condition is met, the terminal device can trigger a reporting process to indicate to the network device that the terminal device does not meet the low-speed movement criterion.

[0119] Optionally, the mobility status of the terminal device can be reported via RRC signaling or MAC signaling.

[0120] Optionally, RRC signaling can be RRC-specific signaling, and MAC signaling can be MAC CE.

[0121] Signaling can be RRC-specific signaling, MAC CE, etc.

[0122] Furthermore, in this embodiment of the invention, the terminal device can also report the measurement results of the serving cell of the terminal device.

[0123] Correspondingly, network devices can receive measurement results of the serving cell reported by terminal devices.

[0124] Optionally, the measurement results of the serving cell reported by the terminal device can be reported proactively by itself or reported based on instructions from the network device.

[0125] Optionally, before the terminal device receives the measurement results of the serving cell reported by the terminal device, the network device may instruct the terminal device to report the measurement results of the serving cell to the network device.

[0126] The measurement results of the serving cell of the terminal device may include the measured value of the reference signal received signal strength, i.e., the measured value of RSRP, and / or the measured value of RSRQ.

[0127] Optionally, the terminal device may, under the configuration of the network device (for example, in step 1, the RRC dedicated signaling instructs the terminal device to simultaneously report the serving cell measurement results), add the reporting of the serving cell measurement results of the terminal device during the process of reporting the mobility status of the terminal device.

[0128] It should be noted that, in this embodiment of the invention, the two pieces of information, namely the mobility status of the terminal device and the measurement result of the serving cell, can be reported to the network device in the same message (e.g., in the same RRC dedicated signaling, or in the same MAC CE). Alternatively, these two pieces of information can be reported to the network device in different messages (e.g., the mobility status of the terminal device is carried in the RRC dedicated signaling, and the measurement result of the serving cell is carried in the MAC CE).

[0129] Furthermore, when the mobility status of the terminal device and the measurement result of the serving cell are reported to the network device in different messages, the embodiments of the present invention do not limit the reporting order of these two pieces of information. That is, the mobility status of the terminal device can be reported first, followed by the measurement result of the serving cell; the measurement result of the serving cell can be reported first, followed by the mobility status of the terminal device; or the mobility status of the terminal device and the measurement result of the serving cell can be reported simultaneously.

[0130] 204. Network equipment determines the cell measurement status.

[0131] The cell measurement status can refer to the state in which the terminal device performs cell measurements. The cell measurement status includes: relaxed measurement, and / or, normal measurement.

[0132] After receiving the mobility status reported by the terminal device, the network device can determine whether to determine the cell measurement status based on the mobility status. Based on the determination result, it can determine the cell measurement status based on the mobility status reported by the terminal device, or it can determine the cell measurement status based on other parameters.

[0133] Optionally, among the parameters used by the network device to determine the cell measurement status, if the signal quality of the serving cell has a higher priority than the mobility status of the terminal device, the network device can determine that it will not determine the cell measurement status based on the mobility status of the terminal device, but rather based on the signal quality of the serving cell.

[0134] Optionally, among the parameters used by the network device to determine the cell measurement status, if the signal quality of the serving cell has a higher priority than the mobility status of the terminal device, the network device can determine the cell measurement status based on the signal quality of the serving cell and the mobility status of the terminal device.

[0135] Optionally, among the parameters used by the network device to determine the cell measurement status, if the signal quality of the serving cell has a lower priority than the mobility status of the terminal device, the network device can determine the cell measurement status based on the mobility status of the terminal device.

[0136] Optionally, among the parameters used by the network device to determine the cell measurement status, if the signal quality of the serving cell has a lower priority than the mobility status of the terminal device, the network device can determine the cell measurement status based on the signal quality of the serving cell and the mobility status of the terminal device.

[0137] The network devices described above can determine the cell measurement status in the following two possible ways:

[0138] In one possible implementation, the network device can determine the cell measurement status based on the movement status of the terminal device reported by the terminal device.

[0139] In another possible implementation, the network device can determine the cell measurement status based on other parameters.

[0140] For example, the network device can obtain the signal quality of the serving cell of the terminal device, and then determine whether the signal quality of the serving cell of the terminal device is greater than a signal quality threshold. If the signal quality of the serving cell is greater than the signal quality threshold, it is determined that the terminal device is not at the edge of the serving cell. At this time, the probability of the terminal device performing cell handover is small, and the terminal device can determine that the cell measurement state is relaxed measurement. If the signal quality of the serving cell is less than or equal to the signal quality threshold, it is determined that the terminal device is at the edge of the serving cell. At this time, the probability of the terminal device performing cell handover is large, and the cell measurement state can be determined to be relaxed measurement.

[0141] For example, after receiving the mobility status of the terminal device reported by the terminal device, if the terminal device is in a low-speed mobility state, the network device can further determine whether the signal quality of the serving cell of the terminal device is greater than the signal quality threshold. If the signal quality of the serving cell is greater than the signal quality threshold, it is determined that the terminal device is not at the edge of the serving cell. At this time, the terminal device is not at the edge of the serving cell and is in a low-speed mobility state, so the probability of the terminal device performing cell handover is small, and the terminal device can determine that the cell measurement state is relaxed measurement. If the signal quality of the serving cell is less than or equal to the signal quality threshold, it is determined that the terminal device is at the edge of the serving cell. At this time, although the terminal device is in a low-speed mobility state, it is at the edge of the serving cell, so the terminal device may perform cell handover. At this time, the cell measurement state can be determined as normal measurement.

[0142] For example, after receiving the mobility status of the terminal device reported by the terminal device, if the mobility status of the terminal device is not low-speed mobility, the network device can further determine whether the signal quality of the serving cell of the terminal device is greater than the signal quality threshold. If the signal quality of the serving cell is greater than the signal quality threshold, it is determined that the terminal device is not at the edge of the serving cell. At this time, although the terminal device is in a non-low-speed mobility state, it is not at the edge of the serving cell, so the possibility of the terminal device performing cell handover is small, and the terminal device can determine that the cell measurement status is relaxed measurement. If the signal quality of the serving cell is less than or equal to the signal quality threshold, it is determined that the terminal device is at the edge of the serving cell. At this time, the terminal device is at the edge of the serving cell and is in a non-low-speed mobility state, so the probability of the terminal device performing cell handover is large, and the cell measurement status can be determined as normal measurement.

[0143] 205. The network device sends a measurement command to the terminal device.

[0144] Following step 204 above, the network device can indicate the cell measurement status to the terminal device. Optionally, this can be achieved through step 205 above.

[0145] Optionally, the above measurement instructions can be determined based on the movement status of the terminal device, and the measurement instructions can be used to instruct the terminal device to perform a relaxation measurement, and / or to instruct the terminal device to perform a normal measurement.

[0146] Optionally, if the terminal device reports the measurement results of the serving cell to the network device, the measurement instruction can also be determined based on the terminal device's mobility status and the measurement results of the serving cell.

[0147] For example, in this embodiment of the invention, when the network device receives a measurement of the terminal device's movement state as low-speed movement, it can further determine whether the signal quality of the serving cell in the measurement results of the serving cell is greater than a certain threshold. If the signal quality of the serving cell is greater than the threshold, it indicates that the current signal quality of the serving cell is relatively good, and the need for cell reselection is not significant. In this case, the low-speed movement state of the terminal device and the signal quality of the serving cell can be combined to comprehensively determine whether to perform relaxed measurement on the serving cell and / or neighboring cells. If the signal quality of the serving cell is less than or equal to the threshold, it indicates that the current signal quality of the serving cell is relatively poor, and the need for cell reselection is significant. In this case, the low-speed movement state of the terminal device and the signal quality of the serving cell can be combined to comprehensively determine whether to perform normal measurement on the serving cell and / or neighboring cells.

[0148] Optionally, the measurement instruction may include the following:

[0149] Case 1: The measurement command is a measurement command for the serving cell of the terminal device;

[0150] Case 2: The measurement command is a measurement command for the neighboring cells of the terminal device (i.e., the neighboring cells of the serving cell of the terminal device);

[0151] Case 3: The measurement command is a measurement command for the serving cell and neighboring cells of the terminal device.

[0152] 206. The terminal equipment performs cell measurements according to the measurement instructions.

[0153] Optionally, for situation 1 above, the terminal device may perform normal measurement on the serving cell of the terminal device, or relax the measurement; for situation 2 above, the terminal device may perform normal measurement on the neighboring cells of the serving cell of the terminal device, or relax the measurement; for situation 3 above, the terminal device may perform normal measurement on the serving cell of the terminal device, or relax the measurement, and perform normal measurement on the neighboring cells of the serving cell, or relax the measurement.

[0154] The cell measurement indication method provided in this embodiment of the invention allows a network device to send low-speed mobility target assessment parameters to a terminal device. The terminal device can then assess its own mobility status based on these assessment parameters and the measurement results of the serving cell, and report its mobility status to the network device. This allows the network device to know the mobility status of the terminal device and instruct it to perform cell measurements (normal measurement, and / or relaxed measurement). This provides a cell measurement scheme that is controllable by the network device.

Figure 6 The mobile phone structure shown does not constitute a limitation on the mobile phone and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0276] RF circuit 610 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with processor 680; additionally, it transmits uplink data to the base station. Typically, RF circuit 610 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, etc. Furthermore, RF circuit 610 can also communicate wirelessly with networks and other devices.

In addition, the memory 620 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

When stationary, it can detect the magnitude and direction of gravity, and can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition-related functions (such as pedometer, taps), etc. Other sensors that may be configured in the mobile phone, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

On the other hand, microphone 662 converts collected sound signals into electrical signals, which are received by audio circuit 660, converted into audio data, and then output to processor 680 for processing. The audio data is then transmitted via RF circuit 610 to, for example, another mobile phone, or output to memory 620 for further processing.

Through the WiFi module 670, mobile phones can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 6 The WiFi module 670 is shown, but it is understood that it is not an essential component of a mobile phone and can be omitted as needed without changing the essence of the invention.

[0283] The processor 680 is the control center of the mobile phone, connecting various parts of the phone through various interfaces and lines.
