Background

At present, the capacity and coverage of a cell are balanced, and in order to ensure the balance between the network capacity and the network coverage, a Capacity and Coverage Optimization (CCO) mechanism can be considered. The purpose of the CCO is to provide a larger capacity in a target coverage area, that is, to ensure the service throughput of a connected terminal device in a cell, ensure the service quality, and reduce the interference of service transmission of the terminal device to the cell or an adjacent cell.

However, under the current CCO mechanism, the network device may not be able to obtain the neighboring cell situation of the location where the terminal device is located in time, so that reasonable capacity optimization cannot be performed in time when the capacity of the network device is reduced.

Detailed Description

To facilitate understanding of the technical solutions of the embodiments of the present application, a brief description of the related art of the present application is first given as follows.

Radio Resource Control (RRC) state:

in the embodiment of the present application, the RRC state of the terminal device may be divided into an RRC connected state and an RRC unconnected state. When the terminal device is in the RRC connected state, an RRC connection exists between the terminal device and the network device, and when the terminal device is in the RRC non-connected state, an RRC connection does not exist between the terminal device and the network device (such as an access network device).

Illustratively, the RRC CONNECTED state may include an RRC CONNECTED state (RRC _ CONNECTED), and the RRC unconnected state may include at least one of an RRC deactivated dynamic state (RRC _ INACTIVE) and an RRC IDLE state (RRC _ IDLE).

It is to be understood that the present application does not limit the RRC non-connected state to include only the RRC deactivation dynamic and the RRC idle state, and other RRC non-connected states may occur in future protocols.

Taking a New Radio (NR) system as an example, in NR, when a terminal device is in an RRC connected state, the terminal device has already established a connection with an access network device and a core network device, and the terminal device can perform data transmission with the network device; when the terminal equipment is in the RRC deactivation dynamic state, the terminal equipment reserves the link between the access network equipment and the core network equipment of the terminal equipment and releases the link between the access network equipment and the terminal equipment. At this time, the terminal device and the access network device store the context of the terminal device, and when there is data to be transmitted, the terminal device can quickly recover the link between the terminal device and the access network device. When the terminal device is in an RRC idle state, the terminal device releases a link between the terminal device and the access network device and a link between the terminal device and the core network device.

For example, the three states can be switched as shown in fig. 1. When the terminal equipment is in an RRC idle state, the terminal equipment can enter an RRC connection state by establishing RRC connection with the network equipment; when the terminal equipment is in an RRC connection state, the network equipment can release the RRC connection of the terminal equipment and configure the terminal equipment to enter an RRC deactivation dynamic state or an RRC idle state; when the terminal device is in the RRC deactivation dynamic state, a request for recovering the RRC connection may be initiated, and the network device may configure the terminal device to enter an RRC connection state or an idle state.

It should be understood that the RRC state is only an example, and should not limit the present application. This application also does not exclude the definition of other possible names in future protocols instead of the existing names, but having the same or similar characteristics, or possibly other states.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Where in the description of the present application, "/" indicates a relationship where the objects associated before and after are an "or", unless otherwise stated, for example, a/B may indicate a or B; in the present application, "and/or" is only an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. Also, in the description of the present application, "at least one" means one or more, "a plurality" means two or more, unless otherwise specified. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

The technical scheme of the embodiment of the application can be applied to various communication systems. For example: orthogonal frequency-division multiple access (OFDMA), single carrier frequency-division multiple access (SC-FDMA), non-terrestrial network (NTN), and other systems. The term "system" may be used interchangeably with "network". The OFDMA system may implement wireless technologies such as evolved universal radio access (E-UTRA), Ultra Mobile Broadband (UMB), and the like. E-UTRA is an evolved version of the Universal Mobile Telecommunications System (UMTS). The third generation partnership project (3 GPP) is using a new version of the E-UTRA in Long Term Evolution (LTE) and various versions based on LTE evolution. The fifth generation (5G) communication system is a next generation communication system under study. The 5G communication system includes a non-standalone (NSA) 5G mobile communication system, a Standalone (SA) 5G mobile communication system, or an NSA 5G mobile communication system and an SA 5G mobile communication system. In addition, the communication system can also be applied to future-oriented communication technologies, and the technical solutions provided by the embodiments of the present application are all applied. The above-mentioned communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited thereto, and is herein collectively described, and will not be described again.

Fig. 2 shows a communication system 20 according to an embodiment of the present application. The communication system 20 includes at least one network device 30, and one or more terminal devices 40 connected to the network device 30. Alternatively, different terminal devices 40 may communicate with each other.

Taking the example that the network device 30 shown in fig. 2 communicates with any terminal device 40, in this embodiment of the application, the network device 30 determines the first information and then sends the first information to the terminal device 40, so that the terminal device 40 can determine the first configuration information, where the first configuration information includes the first threshold. In a case where the terminal device 40 is in an RRC non-connected state and a measurement result of a serving cell of the terminal device 40 is less than or equal to a first threshold, a first measurement is performed, where the first measurement is used for measuring at least one frequency point.

Based on the scheme, reasonable measurement can be carried out in the RRC non-connection state, so that more reasonable judgment can be conveniently carried out by the network equipment, and the capacity performance is improved. For example, since the terminal device performs the frequency point measurement when in the RRC non-connected state, when the terminal device measures that there is a good quality neighbor cell, the terminal device can immediately report the neighbor cell information to the network device when in the RRC connected state, so that the network device can obtain the neighbor cell information of the terminal device in time, thereby performing capacity optimization, such as handover judgment, in time according to the neighbor cell information; under the condition that the terminal device does not measure the neighbor cell with better quality, when the terminal device is in an RRC connection state, the terminal device can send indication information indicating the neighbor cell with better quality, so that the network device can more reasonably perform capacity optimization according to the indication, for example, the terminal device is released, or the terminal device does not need to be indicated by the indication information to measure the cell with better quality, and the network device can preferentially switch the terminal device reporting the neighbor cell information during capacity optimization.

The CU and the DU may be physically separated or disposed together, which is not specifically limited in this embodiment of the application. The CU and DU may be connected via an interface, such as an F1 interface. CUs and DUs may be partitioned according to protocol layers of the wireless network. For example, the functions of a Radio Resource Control (RRC) protocol layer, a Service Data Adaptation Protocol (SDAP) protocol layer, and a Packet Data Convergence Protocol (PDCP) protocol layer are provided in the CU, and the functions of a Radio Link Control (RLC) protocol layer, a Medium Access Control (MAC) protocol layer, a Physical (PHY) protocol layer, and the like are provided in the DU. It is understood that the division of the CU and the DU processing functions according to the protocol layer is only an example, and may also be performed in other manners, which is not specifically limited in this embodiment of the present application.

Alternatively, a CU may be composed of a CU control plane (CU-CP) and a CU user plane (CU-UP), and the CU-CP and the CU-UP may be understood as dividing the CU from the perspective of a logical function. The CU-CP and CU-UP may be connected via an interface, which may be, for example, an E1 interface. The CU-CP and the CU-UP may be divided according to protocol layers of a wireless network, for example, functions of a PDCP protocol layer corresponding to an RRC protocol layer and a Signaling Radio Bearer (SRB) are set in the CU-CP, and a function of a PDCP protocol layer corresponding to a Data Radio Bearer (DRB) is set in the CU-UP. In addition, the functions of the SDAP protocol layer may also be located in the CU-UP.

The following describes the measurement method provided in the embodiment of the present application by taking the network device 30 shown in fig. 2 as an example of interaction with any terminal device 40, with reference to the accompanying drawings.

It is understood that, in the embodiments of the present application, a terminal device and/or a network device may perform some or all of the steps in the embodiments of the present application, and these steps or operations are merely examples, and the embodiments of the present application may also perform other operations or various modifications of the operations. Further, the various steps may be performed in a different order presented in the embodiments of the application, and not all operations in the embodiments of the application may be performed.

It can be understood that, in the embodiments of the present application, the interaction between the network device and the terminal device may also be applied to the interaction between the CU and the terminal device, or the interaction between the DU and the terminal device. It can be understood that, in various embodiments of the present application, the interaction mechanism between the network device and the terminal device may be modified appropriately to adapt to the interaction between the CU or the DU and the terminal device.

It should be noted that, in the following embodiments of the present application, names of messages between network elements or names of parameters in messages are only an example, and other names may also be used in a specific implementation, which is not specifically limited in this embodiment of the present application.

As shown in fig. 7, a measurement method provided in an embodiment of the present application includes the following steps:

s701, the terminal device determines first configuration information.

Wherein the first configuration information includes a first threshold.

Optionally, the type of the first threshold may be at least one of the following: a Received Signal Code Power (RSCP) threshold, a Reference Signal Received Power (RSRP) threshold, a Reference Signal Received Quality (RSRQ) threshold, a signal to noise ratio (SNR) threshold, a signal to interference plus noise ratio (SINR) threshold, a Reference Signal Strength Indication (RSSI) threshold, and other signal quality thresholds.

In some possible embodiments, the terminal device may determine the first configuration information according to a configuration of the network device or a notification or indication. Or, optionally, in an implementation scenario of the embodiment of the present application, in step S701, the first threshold may also be determined for the terminal device. At this time, the first threshold may be determined by the terminal device, that is, the terminal device may not determine the first threshold according to the relevant configuration information of the network device; alternatively, in another implementation scenario of the embodiment of the present application, the first threshold may be specified by a protocol.

After the terminal device is in the RRC non-connected state, the serving cell of the terminal device may be measured to obtain a measurement result of the serving cell. In case that the measurement result of the serving cell of the terminal device is smaller than the first threshold, performing the following step S702; in case that the measurement result of the serving cell of the terminal device is greater than the first threshold, performing the following step S704; when the measurement result of the serving cell of the terminal device is equal to the first threshold, the following step S702 may be executed, or the following step S704 may also be executed, which is not specifically limited in this embodiment of the application.

Optionally, the measurement result of the serving cell may include at least one of the following: RSCP, RSRP, RSRQ, SNR, SINR, RSSI, or other signal quality. In the case where the first threshold comprises a plurality of types of thresholds:

in one possible implementation manner, the terminal device measures the serving cell according to the type of each threshold included in the first threshold, that is, the measurement result of the serving cell corresponds to the type of the first threshold one to one. In the embodiment of the present application, the types of the first threshold are an RSRQ threshold and an RSRP threshold, and accordingly, the measurement result of the serving cell includes the RSRQ and the RSRP.

Optionally, in this implementation, when comparing the size relationship between the measurement result of the serving cell of the terminal device and the first threshold, each measurement result may be compared with a threshold of a corresponding type. For example, the RSRQ of the serving cell is compared to an RSRQ threshold, and the RSRP of the serving cell is compared to an RSRP threshold.

Optionally, in this implementation, the measurement result of the serving cell and the first threshold satisfy a certain size relationship (e.g., less than or equal to), and the size relationship may be satisfied by respective types of thresholds in the measurement results of the serving cell and the first threshold. For example, the measurement result of the serving cell being less than or equal to the first threshold may be: the RSRQ of the serving cell is less than or equal to the RSRQ threshold in the first threshold and the RSRP of the serving cell is less than or equal to the PSRP in the first threshold.

In another possible implementation manner, the terminal device measures the serving cells according to a part of thresholds included in the first threshold, that is, the number of measurement results of the serving cells is less than or equal to the number of types of the first threshold. In the embodiment of the present application, the type of the first threshold is an RSRQ threshold and an RSRP threshold, and the measurement result of the serving cell is an RSRP.

Optionally, a part of the thresholds included in the first threshold may be one or more thresholds that the network device indicates to the terminal device, which is not specifically limited in this embodiment of the present application.

Optionally, in this implementation, when comparing the size relationship between the measurement result of the serving cell of the terminal device and the first threshold, each measurement result of the serving cell may be compared with a threshold of a corresponding type in a part of thresholds included in the first threshold. For example, the type of the first threshold is an RSRQ threshold and an RSRP threshold, and a partial threshold included in the first threshold is an RSRP threshold, and if the measurement result type of the serving cell is RSRP, the RSRP of the serving cell may be compared with a corresponding RSRP threshold in the partial threshold.

Optionally, in this implementation, a partial threshold included by the measurement result of the serving cell and the first threshold satisfies a certain size relationship (e.g., is less than or equal to) and the size relationship may be satisfied for a corresponding type of threshold in the partial threshold included by the measurement result of the serving cell and the first threshold. For example, the measurement result of the serving cell being less than or equal to the first threshold may be: the RSRP of the serving cell is less than or equal to the RSRP in the first threshold.

S702, the terminal equipment executes first measurement.

That is, in a case where the terminal device is in an RRC non-connected state and a measurement result of a serving cell of the terminal device is less than or equal to a first threshold, a first measurement is performed, where the first measurement is used for measuring at least one frequency point.

It should be noted that in the implementation of the present application, the "measurement result" may also be referred to as "measurement quantity" for characterizing the signal quality, and the two may be replaced with each other, or the "measurement result" may also be referred to as "signal quality"; the "first measurement" may also be referred to as an "early handover measurement", which may be substituted for each other.

Alternatively, the early handover measurement may refer to a measurement performed for handover in a case where the terminal device is in an RRC non-connected state, that is, the first measurement may refer to a measurement for performing early handover. Alternatively, the early handover measurement may refer to a measurement performed by a terminal device in an RRC non-connected state in a case where a measurement result of the serving cell is less than or equal to a first threshold.

Optionally, the at least one frequency point measured by the first measurement may include a frequency point that is the same as a frequency point of a serving cell of the terminal device, or may include a frequency point that is different from a frequency point of the serving cell of the terminal device. The at least one frequency point may include a frequency point in a system (or standard) that is the same as a system (or standard) of a serving cell of the terminal device, or may also include a frequency point in a system (or standard) that is different from the system (or standard) of the serving cell of the terminal device, which is not specifically limited in this embodiment of the present application.

Alternatively, the measurement may be of particle size in at least one of the following: a cell, a beam, a synchronization signal/physical broadcast channel Block (SSB), a channel-state information reference signal (CSI-RS), an air interface technology (null), a slicing (slicing), or a partial Bandwidth (BWP). Wherein different air interface technologies correspond to different subcarrier spacings.

It is understood that beams, SSBs, CSI-RS, air interface technology, slices, BWP are relevant attributes of a cell, for example, a cell may include multiple beams, each for carrying one SSB, i.e., beams, SSBs, CSI-RS, air interface technology, slices, BWP are more fine-grained compared to a cell.

That is, the terminal device performing the first measurement may include: and the terminal equipment determines the cell on the at least one frequency point, and then performs measurement by taking at least one of the cell, the beam, the SSB, the CSI-RS, the air interface technology, the slice or the BWP as granularity.

In the embodiment of the present application, any cell measured by the terminal device is referred to as a first cell. It can be understood that the terminal device may measure all or part of the cells on all or part of the above at least one frequency point. That is to say, all the first cells measured by the terminal device may include one or more cells on the first frequency point, where the first frequency point is one or more frequency points belonging to at least one frequency point required to be measured by the first measurement.

For example, taking the first measurement for measuring frequency point 1, frequency point 2, and sum frequency point 3, the cells on frequency point 1 are cell a and cell B, the cells on frequency point 2 are cell C and cell D, and the cells on frequency point 3 are cell E and cell F as an example, the first frequency point may be one or more frequency points in the 3 frequency points, for example, the first frequency point is frequency point 1 and frequency point 3, all the first cells are one or more cells on frequency point 1, and one or more cells on frequency point 3, for example, all the first cells are cell a, cell B, and cell E.

Optionally, the granularity of the measurement result may be the same as the granularity of the measurement performed, or may be determined based on the granularity of the measurement performed, for example, when the beam is the granularity of the measurement performed, the granularity of the measurement result may be the beam, or may be the cell, for example, the measurement result of the cell is a result obtained by weighting the beam measurement result. That is, in this embodiment of the present application, the measurement result of the cell may be at least one of the following: a measurement result with a cell as granularity, a measurement result with a cell beam as granularity, a measurement result with a cell SSB as granularity, a measurement result with a cell CSI-RS as granularity, a measurement result with an air interface technology used by a cell as granularity, a measurement result with a cell slice as granularity, or a measurement result with a cell BWP as granularity.

Optionally, the measurement result may include at least one of the following: RSCP, RSRP, RSRQ, SNR, SINR, RSSI, or other signal quality.

Alternatively, the measurement result may be obtained by measuring at least one of: a downlink synchronization channel, a channel-state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a cell-specific reference signal (CRS) signal, a Synchronization Signal (SS), a synchronization signal/physical broadcast channel Block (SS/PBCH Block, or SSB), or other downlink signals.

Illustratively, taking the measurement result obtained by measuring the CSI-RS, the measurement result including RSRP as an example, the terminal device may measure the CSI-RS of different beams in the cell, so as to obtain RSRP with the beams as granularity, i.e., obtain the measurement result of different beams in the cell.

Or, for example, taking that the measurement result is obtained by measuring the SSBs, and the measurement result includes RSRQ as an example, the terminal device may measure different SSBs in the cell, so as to obtain RSRQ with SSBs as granularity, that is, the measurement result of different SSBs in the cell.

Optionally, the terminal device may record measurement result information of the first cell in the process of performing the first measurement. Wherein the measurement result information of the first cell includes identification information related to the first cell, or includes identification information related to the first cell and a measurement result of the first cell. The measurement result information of the first cell may also be referred to as neighbor cell information of a serving cell of the terminal device.

Optionally, the identification information related to the first cell may include at least one of a Cell Global Identifier (CGI) of the first cell, a Physical Cell Identifier (PCI) of the first cell, an identifier of the first frequency point, or a cell identifier of the first cell. The identification information associated with the first cell may further comprise at least one of: the method comprises the steps of beam identification of a first cell, synchronous signal/physical broadcast channel block identification of the first cell, CSI-RS identification of the first cell, air interface technology identification used by the first cell, slice identification of the first cell and BWP identification of the first cell.

Based on the scheme, reasonable measurement can be carried out in the RRC non-connection state, so that more reasonable judgment can be conveniently carried out by the network equipment, and the capacity performance is improved. For example, since the terminal device performs the frequency point measurement when in the RRC non-connected state, when the terminal device measures that there is a good quality neighboring cell, the terminal device can report the information of the neighboring cell to the network device when in the RRC connected state, so that the network device can obtain the information of the neighboring cell of the terminal device in time, thereby performing capacity optimization, such as handover judgment, according to the information of the neighboring cell in time; under the condition that the terminal device does not measure the neighbor cell with better quality, when the terminal device is in an RRC connection state, the terminal device can send indication information indicating the neighbor cell with better quality, so that the network device can more reasonably perform capacity optimization according to the indication, for example, the terminal device is released, or the terminal device does not need to be indicated by the indication information to measure the cell with better quality, and the network device can preferentially switch the terminal device reporting the neighbor cell information during capacity optimization.

Optionally, in an implementation scenario of the embodiment of the present application, in step S701, the first configuration information determined by the terminal device may further include one or more of the following: measurement target configuration information, a second threshold, or measurement time information. The relevant description of the various parameters is as follows:

the measurement target configuration information configures at least one frequency point required to be measured by the first measurement. The measurement target configuration information may include frequency point information of each of the at least one frequency point, for example, an Absolute Radio Frequency Channel Number (ARFCN) of each frequency point. The measurement target configuration information may further configure subcarrier spacing information of each frequency point, and/or a synchronization signal/physical broadcast channel block measurement time configuration (SMTC) of each frequency point, and the SMTC may configure at least one of a period, a time domain length, and a start position offset of the SSB.

The second threshold is used for the terminal equipment to determine whether to report the measurement result information of the first cell. Optionally, the second threshold may be an absolute threshold, and in this case, the second threshold may be greater than the first threshold; alternatively, the second threshold may be a relative threshold (or referred to as a threshold offset).

Optionally, when the second threshold is an absolute threshold, the type of the second threshold may be at least one of the following: RSCP threshold, RSRP threshold, RSRQ threshold, SNR threshold, SINR threshold, RSSI threshold, or other signal quality thresholds; when the second threshold is a relative threshold, the type of the second threshold may be at least one of the following: RSCP relative threshold, RSRP relative threshold, RSRQ relative threshold, SNR relative threshold, SINR relative threshold, RSSI relative threshold, or other signal quality relative threshold.

The measurement time information indicates a maximum length of time for the terminal device to perform the first measurement. For example, in step S702, the terminal device may start a first timer at the time of starting to perform the first measurement. The length of the first timer is the time length indicated by the measurement time information. During the running time of the first timer, the terminal equipment executes a first measurement; after the first timer is stopped, the terminal device may stop the first measurement, so that the terminal device may be prevented from continuously performing measurement before accessing the network device, and power consumption of the terminal device may be reduced.

Optionally, as a possible implementation manner, if the terminal device enters the RRC connected state during the running time of the first timer, the terminal device may also stop the first measurement.

Optionally, in an implementation scenario of the embodiment of the present application, the maximum time length indicated by the second threshold and/or the measurement time information may also be specified by a protocol, or may be determined by the terminal device itself, which is not specifically limited in the embodiment of the present application.

Optionally, after the terminal device performs the first measurement, the neighboring cell with better quality may be measured, or the neighboring cell with better quality may not be measured.

In an implementation scenario of the embodiment of the present application, in the process that the terminal device performs the first measurement in step S702, when the second threshold is an absolute threshold and the measurement result of the first cell is greater than or equal to the second threshold, the terminal device determines to report measurement result information of the first cell; or, the terminal device determines to report the measurement result information of the first cell when the second threshold is a relative threshold (or threshold offset) and a difference between the measurement result of the first cell and the measurement result of the serving cell of the terminal device is greater than or equal to the second threshold. That is to say, in this embodiment of the application, when the measurement result of the first cell is greater than or equal to the second threshold, or when a difference between the measurement result of the first cell and the measurement result of the serving cell of the terminal device is greater than or equal to the second threshold, the terminal device determines to report the measurement result information of the first cell. At this time, it may be considered that the terminal device measures a neighboring cell with better quality.

Optionally, the comparison between the measurement result of the first cell and the second threshold may refer to the comparison between the measurement result of the serving cell and the first threshold, and details are not repeated here.

It can be understood that, when performing the first measurement, the terminal device is in an RRC non-connected state, and when determining to report the measurement result information of the first cell, the terminal device cannot immediately send the measurement result information of the first cell to the network device, so that the terminal device may record the measurement result information of the first cell, and send the recorded measurement result information of the first cell to the network device when the terminal device transitions to an RRC connected state.

Optionally, in this scenario, the step S702 where the terminal device records measurement result information of the first cell may be: and the terminal equipment records the measurement result information of the first cell meeting the second threshold condition. In this embodiment, a first cell whose measurement result is greater than or equal to the second threshold, or a first cell whose difference between the measurement result and the measurement result of the serving cell of the terminal device is greater than or equal to the second threshold, is referred to as a first cell that satisfies the second threshold condition.

That is, after obtaining the measurement result information of the first cell, the terminal device compares the measurement result of the first cell with the second threshold, and records the measurement result information of the first cell when the measurement result information of the first cell meets the second threshold condition.

Optionally, the measurement result information of the first cell recorded by the terminal device is not valid for a long time.

In one possible implementation, the measurement result information of the first cell is valid for a preset time period from the time when the recording by the terminal device is completed. Within the preset time, the terminal device does not enter the RRC connected state or the terminal device does not send a measurement report to the network device, and the terminal device may delete the measurement result information of the first cell, or the terminal device may consider that the measurement result information is invalid and does not send the measurement result information after the terminal device enters the RRC connected state.

In another possible implementation manner, the terminal device may start the second timer when recording the measurement result information of the first cell. During the second timer running time, the measurement result information of the first cell is valid; if the second timer is out of time and the terminal device does not enter the RRC connected state or the terminal device does not send a measurement report to the network device, the terminal device may delete the measurement result information of the first cell, or the terminal device may consider that the measurement result information is invalid and does not send the measurement result information after the terminal device enters the RRC connected state. The time length of the second timer may be predefined by the protocol or may be sent by the network device to the terminal device.

In another possible implementation manner, if the quality of the serving cell of the terminal device is improved before the terminal device enters the RRC connected state or before the terminal device sends the measurement report to the network device, for example, the measurement result of the serving cell is greater than or equal to the third threshold, the terminal device may delete the recorded measurement result information of the first cell. Optionally, if the measurement result of the serving cell is greater than or equal to the third threshold, the terminal device may also stop the first measurement, and subsequently does not send the measurement report of any cell obtained through the first measurement to the network device.

In another possible implementation manner, the terminal device may start the third timer when recording the measurement result information of the first cell. If the quality of the serving cell of the terminal device is improved within the time allowed by the third timer, for example, the measurement result of the serving cell is greater than or equal to a third threshold, the terminal device may stop the third timer and delete the recorded measurement result information of the first cell. Optionally, if the measurement result of the serving cell is greater than or equal to the third threshold, the terminal device may also stop the first measurement, and subsequently does not send the measurement report of any cell obtained through the first measurement to the network device.

Optionally, the third threshold may be the same as the first threshold or different from the first threshold, which is not specifically limited in this embodiment of the application.

In another possible implementation manner, in step S702, the terminal device may perform multiple measurements on the first cell. Under the condition that the terminal device records the measurement result information of the first cell after measuring the first cell for the nth time, if the measurement result of the first cell obtained by the (n + 1) th measurement is greater than or equal to a second threshold, or the difference value between the measurement result of the (n + 1) th measurement and the measurement result of the terminal device serving cell is greater than or equal to the second threshold, the terminal device updates the recorded measurement result information of the first cell into the measurement result information obtained by the (n + 1) th measurement; or, if the measurement result of the cell obtained by the n +1 th measurement is less than or equal to the second threshold, or the difference between the measurement result of the n +1 th measurement and the measurement result of the serving cell of the terminal device is less than or equal to the second threshold, the terminal device deletes the measurement result information of the first cell obtained by the nth measurement recorded by the terminal device.

In another implementation scenario of this embodiment, in the process that the terminal device performs the first measurement in step S702, in a case that a measurement result of the first cell is less than or equal to the second threshold, or a difference between the measurement result of the first cell and a measurement result of a serving cell of the terminal device is less than or equal to the second threshold, the terminal device may not record measurement result information of the first cell. At this time, it may be considered that the terminal device does not measure the neighboring cell with better quality.

Optionally, in a case that the terminal device is in the RRC connected state, if the terminal device stores measurement result information of one or more first cells, the following step S703a may be executed; alternatively, if the terminal device does not store any measurement result information of the first cell, the following step S703b may be executed.

Optionally, when the terminal device is in the RRC connected state, the measurement result information of the first cell is stored, which may be understood as: the terminal equipment stores measurement result information of one or more latest or effective first cells; the reason why the terminal device does not store any measurement result of the first cell may be that the terminal device never measures a good-quality neighboring cell (for example, there is no first cell satisfying the second threshold condition), or the terminal device deletes measurement result information of the previously measured good-quality neighboring cell due to reasons such as the validity duration.

Optionally, the serving cell when the terminal device is in the RRC connected state may be the same as the serving cell of the terminal device in step S701, for example, the serving cell of the terminal device does not change from step S701 to step S703a, S703b, or S704, and at this time, the network device in the following steps S703a, S703b, or S704 may be the network device to which the serving cell of the terminal device belongs in step S701; alternatively, the serving cell when the terminal device is in the RRC connected state may be different from the serving cell of the terminal device in step S701, for example, the serving cell of the terminal device changes during the process from step S701 to step S703a, S703b, or S704, and the network device to which the serving cell belongs may also change.

The following embodiment is first described by taking an example that the serving cell of the terminal device is not changed, and it is understood that the implementation is not limited to this case that the serving cell of the terminal device is not changed.

S703a, the terminal device sends the first measurement report to the network device. Accordingly, the network device receives a first measurement report from the terminal device.

I.e. in case the terminal device is in RRC connected state, a first measurement report is sent to the network device.

Optionally, the terminal device may generate a first measurement report according to the recorded measurement result information of all or part of the first cells, and then send the first measurement report to the network device.

Optionally, the first measurement report may include measurement result information of all the first cells recorded by the terminal device, or the first measurement report may include measurement result information of some of the first cells recorded by the terminal device.

It can be understood that the measurement result information of the first cell recorded by the terminal device may be the measurement result information of the first cell that satisfies the second threshold condition, or the measurement result information of the first cell that is recorded without the second threshold condition.

For example, if the size (size) of the measurement result information of all the first cells recorded by the terminal device is smaller than or equal to the signaling size of the allowed measurement report, the first measurement report may include the measurement result information of all the first cells; if the size of the measurement result information of all the first cells recorded by the terminal device is larger than the signaling size of the allowed measurement report, the first measurement report may include the measurement result information of a part of the first cells, for example, according to the time sequence for recording the measurement result information, the measurement result information of the first cell recorded first or most recently is selected as the content included in the first measurement report to be reported, or according to the size (measurement value) of the measurement result of the cell, the measurement result information of a part of the first cells is selected as the content included in the first measurement report to be reported, for example, according to the size of the measurement result, the measurement result information of a part of the first cells with larger measurement result is selected in descending order or ascending order.

Optionally, the terminal device may send the measurement result of the first cell to the network device through one or more of an RRC setup Complete (RRC setup Complete) message, an RRC Reconfiguration Complete (RRC Reconfiguration Complete) message, an RRC Reestablishment Complete (RRC Reestablishment Complete) message, a user equipment information response (UE information response) message, and an RRC recovery Complete (RRC recovery Complete) message; alternatively, the terminal device may send the first measurement report to the network device through one or more of message 1(message 1, msg1), message 3(message 3, msg3), message 5(message 5, msg5), or message a (message a, msgA) in the random access procedure.

Optionally, after the terminal device sends the first measurement report to the network device, the measurement result information of the first cell included in the first measurement report recorded by the terminal device may be deleted.

After receiving the first measurement report, the network device may perform capacity coverage optimization according to the first measurement report. For example, the handover determination may be performed to handover the terminal device to a neighboring cell with higher quality.

Optionally, the terminal device may send the first measurement report to the network device under different conditions.

In one possible implementation, the terminal device may send the first measurement report to the network device based on an indication of the network device. For example, in the case that the serving cell is overloaded or the capacity of the serving cell is reduced, the network device may send an indication for reporting the measurement report to the terminal, for example, the network device may broadcast the indication; and after the terminal equipment enters the RRC connection state, the terminal equipment sends a first measurement report to the network equipment.

In another possible implementation, the terminal device may send the first measurement report to the network device based on a request of the network device. In this scenario, before step S703a, the method further includes: the network device sends the request information to the terminal device. Accordingly, the terminal device receives the request information from the network device. The request information is used for requesting the terminal equipment to report a first measurement report.

Optionally, the network device may send the request information to the terminal device under different conditions:

in a possible implementation manner, before the step S703a, the method according to this embodiment of the present application further includes: the terminal device sends first indication information to the network device, wherein the first indication information is used for indicating that the terminal device has measurement result information of a first cell, or the first indication information is used for indicating that the terminal device has available measurement result information, or the first indication information is used for indicating that the terminal device has available early handover measurement result information. Correspondingly, the network equipment receives the first indication information from the terminal equipment. In this implementation, the sending, by the network device, the request information to the terminal device may include: and the network equipment sends the request information to the terminal equipment according to the first indication information.

In another possible implementation manner, the sending, by the network device, the request information to the terminal device may include: and after the terminal equipment is accessed to the network equipment, the network equipment sends the request information to the terminal equipment under the condition that the service cell of the terminal equipment is overloaded or the capacity of the service cell of the terminal equipment is reduced.

S703b, the terminal device sends the second indication information to the network device. Correspondingly, the network equipment receives the second indication information from the terminal equipment.

The second indication information may indicate that there is no first cell that satisfies the second threshold condition, that is, the terminal device does not have a neighboring cell with better quality. Alternatively, the second indication information may be used to indicate "the first measurement has been started, but there is no first cell satisfying the second threshold condition".

Optionally, after receiving the second indication information, the network device may determine that the terminal device does not have a neighboring cell with better quality, so as to perform capacity optimization processing according to the second indication information in time. For example, for the case where the first measurement is performed but the neighbor cell with better quality is not measured, the network device regards the neighbor cell of the terminal device as the neighbor cell without better quality, and may preferentially switch the terminal device that has reported the measurement report to the neighbor cell with better quality when performing capacity optimization, and then may not switch the terminal device that has reported the second indication information if the capacity performance of the network device is improved, or may further release the terminal device that has reported the second indication information if the capacity performance of the network device is still poor (i.e., disconnect the RRC connection with the terminal device).

Based on the scheme, under the condition that the terminal device does not measure the neighbor cells with better quality, the network device can be indicated to be free of the neighbor cells with better quality in time, so that the network device can carry out capacity optimization processing according to the indication in time.

Optionally, under the condition that the terminal device does not store the measurement result information of the first cell, the terminal device may also not indicate, through the second indication information, that the terminal device does not have a neighboring cell with better quality or indicate that "the first measurement has been started, but there is no first cell that meets the second threshold condition".

For example, the network device may determine that the terminal device supports the first measurement, but the terminal device does not report the measurement report, and the network device may determine that the terminal device does not measure the neighboring cell with better quality or does not start the first measurement, so that capacity optimization may be performed according to the situation, for example, the terminal device that reports the measurement report may be preferentially switched to the neighboring cell with better quality, and the terminal device that does not report the measurement report may not be switched. That is to say, under the condition that the terminal device does not send the second indication information, the network device may also obtain the coverage and neighboring cell conditions of the location where the terminal device is located in time, so as to perform capacity optimization processing in time.

S704, the terminal device sends third indication information to the network device. Correspondingly, the network device receives the third indication information from the terminal device.

The sending, by the terminal device, the third indication information to the network device may include: and under the condition that the terminal equipment is in the RRC connection state, the terminal equipment sends third indication information to the network equipment.

The third indication information indicates that the measurement result of the serving cell of the terminal device is greater than or equal to the first threshold, or indicates that the terminal device does not start the first measurement.

Optionally, after receiving the third indication information, the network device may obtain that the quality of the serving cell of the terminal device is better, and may preferentially switch the terminal device that reports the measurement report to a neighboring cell with better quality or preferentially release the terminal device that reports the second indication information without switching the terminal device to another cell when the capacity of the network device is reduced and capacity optimization processing is performed.

Based on the scheme, the network equipment can timely acquire the terminal equipment with better quality of the service cell, so that reasonable capacity optimization processing is performed, for example, the terminal equipment can not be switched to other cells.

Optionally, the terminal device may also not indicate, through the third indication information, that the measurement result of the serving cell of the terminal device is greater than or equal to the first threshold, or indicate that the terminal device does not start the first measurement.

For example, the network device may determine that the terminal device supports the first measurement, but the terminal device does not report the measurement report, and the network device may determine that the terminal device does not measure the neighboring cell with better quality or does not start the first measurement, so that capacity optimization may be performed according to the situation, for example, the terminal device that reports the measurement report may be preferentially switched to the neighboring cell with better quality, and the terminal device that does not report the measurement report may not be switched. That is to say, under the condition that the terminal device does not send the third indication information, the network device may also obtain the coverage and neighboring cell conditions of the location where the terminal device is located in time, so as to perform capacity optimization processing in time.

In summary, in an implementation scenario of the embodiment of the present application, a plurality of terminal devices served by a network device may all execute the measurement method provided in the embodiment of the present application, and when the network device performs capacity optimization, the terminal device that has reported a measurement report may be preferentially switched to a cell with better quality. And if the capacity performance of the network equipment is still poor, the terminal equipment reporting the second indication information can be released preferentially from the terminal equipment reporting the second indication information and the terminal equipment reporting the third indication information. For the terminal device reporting the third indication information, the network device may not switch the terminal device to another cell or may not release the terminal device when performing capacity optimization. For a terminal device that does not report a measurement report, second indication information, or third indication information, the network device may not switch the terminal device to another cell or release the terminal device when performing capacity optimization.

Optionally, an embodiment of the present application further provides an implementation manner when a serving cell of the terminal device changes.

In this scenario, optionally, the terminal device may receive the area information sent by the network device in step S701, where the area information is used to indicate an effective area for performing the first measurement. The area information may include identification information of at least two cells, which indicates that an effective area for performing the first measurement is the at least two cells, and the at least two cells include the first serving cell. In the embodiment of the present application, the serving cell before the change (i.e., the serving cell of the terminal device in step S701) is referred to as a first serving cell, and the serving cell after the change (i.e., the serving cell of the terminal device when the terminal device is in the RRC connected state) is referred to as a second serving cell.

When the terminal device moves from the first serving cell to the second serving cell, that is, when the serving cell of the terminal device changes from the first serving cell to the second serving cell, the terminal device may determine whether the second serving cell belongs to the effective area indicated by the area information.

In a case that the second serving cell does not belong to the valid area indicated by the area information, the terminal device may delete the first configuration information corresponding to the first serving cell. In this embodiment of the application, the first configuration information corresponding to the first serving cell is the first configuration information determined in step S701. Optionally, the terminal device may perform some or all steps similar to the above steps S701 to S703a, or S701 to S703b, or S701 to S704, except that the serving cell of the terminal device is the second serving cell, and the network device is a network device to which the second serving cell belongs, for example, if the system message of the second serving cell includes the common measurement configuration information corresponding to the second serving cell, the terminal device may determine the first configuration information corresponding to the second serving cell according to the common measurement configuration information of the second serving cell, and then may continue to perform some or all steps similar to steps S702 to S703a, or S702 to S703b, or S703 to S704. It can be understood that the first configuration information corresponding to the second serving cell and the first configuration information corresponding to the first serving cell may be the same or different.

In a case that the second serving cell belongs to the valid area indicated by the area information, the terminal device may determine first configuration information corresponding to the second serving cell. Optionally, the terminal device may determine, according to the common measurement configuration information of the second serving cell, first configuration information corresponding to the second serving cell; or the terminal device may determine the first configuration information corresponding to the second serving cell according to the common measurement configuration information of the second serving cell and the dedicated measurement configuration information received by the terminal device from the first serving cell. The subsequent terminal device may continue to perform some or all of the steps similar to steps S702-S703a, or S702-S703b, or S702-S704.

Alternatively, if the terminal device has available or valid measurement result information related to the first measurement, the terminal device may send a first measurement report related to the first measurement to the network device to which the second serving cell belongs, that is, perform a step similar to step S702. It can be understood that the first network device corresponding to the first serving cell and the second network device corresponding to the second serving cell may be the same network device or different network devices.

Optionally, the available or valid measurement result information related to the first measurement may be available or valid measurement result information of the first cell recorded when the terminal device is located in the first serving cell, and/or available or valid measurement result information of the first cell recorded when the terminal device is located in the second serving cell.

It can be understood that the first cell measured by the terminal device in the first serving cell and the first cell measured by the terminal device in the second serving cell may be the same cell or different cells.

Optionally, the first measurement report related to the first measurement, which is sent by the terminal device to the network device to which the second serving cell belongs, may include measurement result information of a part or all of available or valid first cells recorded by the terminal device in the first serving cell, and/or measurement result information of a part or all of available or valid first cells recorded by the terminal device in the second serving cell. Or, the first measurement report related to the first measurement, which is sent by the terminal device to the network device to which the second serving cell belongs, may include a first measurement report obtained by performing the first measurement in the first serving cell by the terminal device (referred to as a first measurement report corresponding to the first serving cell), and/or a first measurement report obtained by performing the first measurement in the second serving cell by the terminal device (referred to as a first measurement report corresponding to the second serving cell).

For example, if the terminal device performs the first measurement in the first serving cell but does not perform the first measurement in the second serving cell, the terminal device may send a first measurement report corresponding to the first serving cell to the network device to which the second serving cell belongs. For example, the terminal device may determine the first measurement report corresponding to the first serving cell according to the available or valid measurement result information of the first cell recorded in the first serving cell by the terminal device. Or, the terminal device sends the neighboring cell information of the first serving cell to the network device to which the second serving cell belongs.

For another example, if the terminal device performs the first measurement in the first serving cell and the second serving cell respectively, the terminal device may send, to the network device to which the second serving cell belongs, the measurement result information of the available or valid first cell recorded in the first serving cell by the terminal device, and/or the measurement result information of the available or valid first cell recorded in the second serving cell. Or, the terminal device sends the neighboring cell information of the first serving cell and/or the second serving cell to the network device to which the second serving cell belongs.

For another example, if the terminal device does not perform the first measurement in the first serving cell or the terminal device does not record the available or valid measurement result information of the first cell in the first serving cell, but performs the first measurement in the second serving cell, the terminal device may send the first measurement report corresponding to the second serving cell to the network device to which the second serving cell belongs. For example, the terminal device may determine the first measurement report corresponding to the second serving cell according to the available or valid measurement result information of the first cell recorded in the second serving cell by the terminal device. Or, the terminal device sends the neighboring cell information of the second serving cell to the network device to which the second serving cell belongs.

Optionally, after receiving the first measurement report related to the first measurement, the network device of the second serving cell may determine whether the first cell included in the first measurement report includes a neighboring cell of the second serving cell. When the first cell includes the neighboring cell of the second serving cell, the network device to which the second serving cell belongs may perform capacity coverage optimization according to the neighboring cell information of the second serving cell, for example, when the capacity of the second network device to which the second serving cell belongs decreases, the terminal device is switched to the neighboring cell of the second serving cell with better quality.

The following describes a related implementation of the terminal device determining the first configuration information in step S701.

Based on the embodiment shown in fig. 7, as shown in fig. 8, before step S701, the measurement method provided in the embodiment of the present application further includes:

s700a, the network device determines the first information.

The first information is used for the terminal equipment to determine first configuration information, and the first configuration information is used for configuring the terminal equipment in the RRC non-connected state to execute first measurement under the condition that the measurement result of the serving cell is less than or equal to a first threshold.

It can be understood that the network device may be a network device to which the serving cell (i.e. the first serving cell) of the terminal device in the step S701 belongs, and accordingly, the first configuration information in the step S700a — the following step S700b refers to first configuration information corresponding to the first serving cell; or, the network device may be a network device to which the second serving cell belongs, and accordingly, the first configuration information in step S700 a-the following step S700b refers to the first configuration information corresponding to the second serving cell.

Optionally, the first information may be dedicated measurement configuration information and/or common measurement configuration information, and the dedicated measurement configuration information and/or the common measurement configuration information may be used to configure the terminal device in the RRC non-connected state to perform the first measurement.

It is to be understood that the dedicated measurement configuration information may be measurement configuration information for individual use by a certain terminal device. The dedicated measurement configuration information may be sent to the terminal device via a dedicated message, such as an RRC message. The dedicated measurement configuration information for different terminal devices may be different or the same. The common measurement configuration information may be measurement configuration information for use by a plurality of terminal devices. The common measurement configuration may be sent to the terminal devices via broadcast or multicast messages, such as system messages or multicast service messages. Different terminal devices may use the common measurement configuration information in common.

Based on the scheme, when the first information is the special measurement configuration information, different measurement parameters can be configured for different terminal devices, so that the measurement flexibility is improved; when the first information is the common measurement configuration information, the common measurement configuration information does not need to be sent to each terminal device independently, and signaling overhead can be reduced; when the first information is dedicated measurement configuration information and common measurement configuration information, it may not be necessary to configure all measurement parameters in the dedicated measurement configuration information, that is, some measurement parameters may be sent to the terminal device in the dedicated measurement configuration information, and for measurement parameters that are not sent in the dedicated measurement configuration information, the terminal device may obtain in the common measurement configuration information. By the scheme, the flexibility is improved, and meanwhile, the transmission overhead can be reduced.

S700b, the network device sends the first information to the terminal device. Accordingly, the terminal device receives the first information from the network device.

Alternatively, in case the first information comprises common measurement configuration information, the network device may send the common measurement configuration information in a system message or a multicast message. Accordingly, the terminal device may receive the system message or the multicast message and acquire common measurement configuration information included in the system message or the multicast message.

Optionally, in a case that the first information includes dedicated measurement configuration information, the network device may send the dedicated measurement configuration information to the terminal device through one of an RRC recovery (RRC resume) message, an RRC reconfiguration (RRC reconfiguration) message, an RRC setup (RRC setup) message, and an RRC release (RRC release) message when the terminal device is in an RRC connected state.

Optionally, in a case that the first information includes dedicated measurement configuration information, before step S700b, the measurement method may further include, for example: the network equipment acquires the capability indication information of the terminal equipment. Wherein the capability indication information of the terminal device may indicate whether the terminal device supports the first measurement.

Optionally, the acquiring, by the network device, the capability indication information of the terminal device may include: the network device receives capability indication information of the terminal device from the terminal device, and at this time, the method in the embodiment of the present application may also include: the terminal equipment sends the capability indication information to the network equipment; or, the network device receives the capability indication information of the terminal device from the core network device; or the network device receives the capability indication information of the terminal device from other network devices except the network device, for example, the other network devices may be network devices that the terminal device has previously accessed. In the embodiment of the present application, an example in which the capability indication information of the terminal device indicates that the terminal device supports the first measurement is taken as an example for description.

Optionally, before the network device receives the capability indication information of the terminal device, the network device may request the capability indication information of the terminal device from the terminal device or the core network device or another network device.

In this scenario, in step S700b, the sending, by the network device, the first information to the terminal device may include: and sending the first information to the terminal equipment under the condition that the capability indication information of the terminal equipment indicates that the terminal equipment supports the first measurement.

Based on the scheme, the network equipment sends the first information to the terminal equipment under the condition that the terminal equipment supports the first measurement, so that the resource waste caused by the network equipment sending the first information under the condition that the terminal equipment does not support the first measurement can be avoided.

Based on steps S700a-S700b, in step S701, the terminal device may determine the first configuration information from the first information, i.e. the terminal device may determine the first configuration information from dedicated measurement configuration information and/or common measurement configuration information.

Optionally, in a case that the first configuration information includes the first threshold, the measurement configuration information included in the first information may be different, and correspondingly, the manner in which the terminal device determines the first threshold may also be different:

in a possible implementation manner, the first information only includes dedicated measurement configuration information, and the dedicated measurement configuration information includes a threshold 1, and accordingly, the terminal device may determine the threshold 1 as the first threshold.

In another possible implementation manner, the first information only includes common measurement configuration information, and the common measurement configuration information includes a threshold 2, and accordingly, the terminal device may determine the threshold 2 as the first threshold.

In yet another possible implementation, the first information includes common measurement configuration information and dedicated measurement configuration information. The common measurement configuration information may include a reference threshold and the dedicated measurement configuration information may include a threshold offset, and accordingly, the terminal device may determine the first threshold based on the dedicated measurement configuration information and the common measurement configuration information. For example, the terminal device may determine the first threshold as the sum of the reference threshold and the threshold offset, or may determine the first threshold as the difference between the reference threshold and the threshold offset.

In another possible implementation manner, the first information includes common measurement configuration information and dedicated measurement configuration information, and the dedicated measurement configuration information includes a threshold 1, and the common measurement configuration information includes a threshold 2, and accordingly, the terminal device may determine the threshold 1 as the first threshold, that is, the terminal device is based on the first threshold configured by the dedicated measurement configuration information. Optionally, the threshold 1 and the threshold 2 may be different or the same.

Optionally, in the case that the first configuration information includes a plurality of measurement parameters including the first threshold, in step S701, the determining, by the terminal device, the first configuration information may include: in the case where the first information includes only common measurement configuration information, the terminal device determines the first configuration information from the common measurement configuration information; or, in the case that the first information only includes dedicated measurement configuration information, the terminal device determines the first configuration information according to the dedicated measurement configuration information; alternatively, in a case where the first information includes dedicated measurement configuration information and common measurement configuration information, the terminal device determines the first configuration information from the dedicated measurement configuration information and the common measurement configuration information.

Optionally, in a case that the first information includes dedicated measurement configuration information and common measurement configuration information, in a possible implementation manner, if the dedicated measurement configuration information includes all parameters necessary for performing the first measurement, the terminal device may determine the first configuration information only according to the dedicated measurement configuration information; if the dedicated measurement configuration information comprises a part of the parameters necessary for performing the first measurement, the terminal device may determine the first configuration information from a part of the parameters necessary for performing the first measurement comprised by the dedicated measurement configuration information and from another part of the parameters necessary for performing the first measurement comprised by the common measurement configuration information. For example, in addition to the first threshold, the parameter necessary for performing the first measurement includes measurement target configuration information and a second threshold, and if the dedicated measurement configuration information includes the measurement target configuration information and the common measurement configuration information includes the measurement target configuration information and the second threshold, the first configuration information determined by the terminal device includes the measurement target configuration information included in the dedicated measurement configuration information and the second threshold included in the common measurement configuration information.

Based on the scheme, the method for determining the first configuration information by the terminal equipment under different first information can be provided, and the behavior of the terminal equipment can be normalized, so that the terminal equipment can better perform measurement subsequently.

In addition, in an implementation scenario of the embodiment of the present application, the network device may be a CU, and in the embodiment of the present application, the method and/or the step implemented by the network device may be implemented by the CU; or, the network device may be a DU, and in this embodiment of the present application, the method and/or the step implemented by the network device may be implemented by the DU; or the network device may be composed of a CU and a DU, and in the embodiment of the present application, the method and/or the step implemented by the network device may be implemented by the CU and/or the DU.

For example, when the network device is a CU, the CU may determine the first information in step S700 a; when the network device is a DU, in step S700a, the DU may determine the first information; when the network device is composed of a CU and a DU, in step S700a, the first information may be determined by the DU, or the first information may be determined by the CU, which is not specifically limited in this embodiment of the present application.

In one possible implementation, when the first information is determined by the DU in step S700a, optionally, the DU may send the first information to the CU. Alternatively, before the DU sends the first information to the CU, the CU may request the first information from the DU.

Optionally, the DU may carry the first information in an F1 setup request message or a gNB-DU configuration update message, or a gNB-CU configuration update confirmation message, and send the first information to the CU.

In another possible implementation, when the CU determines the first information in step S700a, optionally, the CU may send the first information to the DU. Optionally, the DU may request the first information from the CU before the CU sends the first information to the DU.

Optionally, the CU may carry the first information in an F1 setup response message, or a gNB-CU configuration update message, or a gNB-DU configuration update confirmation message, and send the message to the DU.

It is understood that, in the above two possible cases, in step S700b, the CU or DU may send the first information to the terminal device.

In the above embodiment shown in fig. 7 or fig. 8, the processor 301 in the network device 30 shown in fig. 5 may call the application program code stored in the memory 302 to instruct the network device to perform the actions of the network device, and in the above embodiment shown in fig. 7 or fig. 8, the processor 401 in the terminal device 40 shown in fig. 5 may call the application program code stored in the memory 402 to instruct the terminal device to perform the actions of the terminal device, which is not limited in this embodiment.

The above-mentioned scheme provided by the embodiment of the present application is introduced mainly from the perspective of interaction between network elements. Correspondingly, the embodiment of the application also provides a communication device, and the communication device is used for realizing the various methods. The communication device may be the terminal device in the above method embodiment, or a device including the above terminal device, or a component that can be used for the terminal device; alternatively, the communication device may be the network device in the above method embodiment, or a device including the above network device, or a component that can be used for the network device. It is to be understood that the communication device comprises corresponding hardware structures and/or software modules for performing the respective functions in order to realize the above-mentioned functions. Those of skill in the art would readily appreciate that the various illustrative elements and algorithm steps described in connection with the embodiments disclosed herein may be implemented as hardware or combinations of hardware and computer software. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

In the embodiment of the present application, the communication apparatus may be divided into functional modules according to the method embodiments, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, in the embodiment of the present application, the division of the module is schematic, and is only one logic function division, and there may be another division manner in actual implementation.

For example, the steps of the communication device implementing the terminal device in the above method embodiment are taken as an example. Fig. 9 shows a schematic structural diagram of a communication device 90. The communication device 90 comprises a processing module 901 and a measuring module 902. Optionally, the communication device 90 may further include a transceiver module 903. The transceiver module 903, which may also be referred to as a transceiver unit, is used for implementing a transmitting and/or receiving function, and may be, for example, a transceiver circuit, a transceiver, or a communication interface.
