[0033] Generally, the traditional communication system supports a limited number of connections, which is easy to implement. However, with the development of communication technology, the mobile communication system will not only support the traditional communication, but also support, for example, Device to Device (D2D) communication, Machine to Machine (M2M) communication, Machine Type Communication (MTC), Vehicle to Vehicle (V2V) communication, or Vehicle to everything (V2X) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0036] The embodiments of the present application can be applied to a non-terrestrial network (NTN) system, and can also be applied to a terrestrial network (TN) system. The NTN generally adopts a satellite communication mode to provide communication services to ground users. The NTN system currently includes an NR-NTN and an IoT-NTN system, and subsequent NTN systems are also possible.

[0037] Please refer to FIG. 1, which shows a schematic diagram of a network architecture 100 provided by an embodiment of the present application. The network architecture 100 can include a terminal device 10, an access network device 20, and a core network element 30.

[0038] The terminal device 10 can refer to a UE (User Equipment), an access terminal device, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal device, a mobile device, a wireless communication device, a user agent, or a user apparatus.

For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed in the cell managed by each access network device 20. The terminal device can also be referred to simply as a terminal device or a UE, and those skilled in the art can understand its meaning.

[0039] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with access network device functions can be different, for example, in a 5G NR system, it is called gNodeB or gNB. As communication technology evolves, the name of the "access network device" may change. For ease of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network element 30. Illustratively, in the LTE (Long Term Evolution) system, the access network device 20 can be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in the EUTRAN; in the 5G NR system, the access network device 20 can be a RAN (Radio Access Network) or one or more gNBs in the RAN. In the embodiments of the present application, the "network device" refers to the access network device 20, such as a base station, unless otherwise specified.

[0040] The core network element 30 is a network element deployed in the core network, and the main functions of the core network element 30 are to provide user connection, manage users, and complete bearer for services, and to provide an interface to external network devices as a bearer network device. For example, the core network element in the 5G NR system can include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, and SMF (Session Management Function) entities.

[0041] In some embodiments, the access network device 20 and the core network element 30 communicate with each other through some air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other through some air interface technology, such as the Uu interface.

[0042] The "5G NR system" in the embodiments of the present application can also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present application can be applicable to the LTE system, the 5G NR system, the subsequent evolution system (such as the B5G (Beyound 5G) system, the 6G system (6th Generation System, the sixth generation mobile communication system)) of the 5G NR system, and other communication systems such as the NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) system, and the like, and the present application does not limit this.

[0043] In the embodiments of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resource (for example, frequency domain resource, or spectrum resource) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station), and the cell can belong to a macro base station or a base station corresponding to a small cell (Small cell). The small cell here can include a metro cell, a micro cell, a pico cell, a femto cell, and the like. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0044] Before introducing the technical solutions of the present application, the related technologies involved in the present application are introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0045] In the traditional NR system, the gNB periodically transmits system messages, which is crucial for idle UEs to access the network device. However, at the same time, the network device cannot predict the number of idle UEs that may need to read the system message. Therefore, some of the periodically transmitted system messages will be naturally wasted. In addition, since the network device must maintain the system message, the base station cannot enter a deep sleep mode to save power. According to the operator's billing records, OPEX (Operating Expenses) due to power consumption accounts for a large part of the billing cost. Therefore, if the energy consumption of the base station can be reduced, it will not only be beneficial to the operation of future cellular systems, but also contribute to the ecology, and strive to reduce carbon emissions to help slow global warming. However, if the base station directly omits the system message, it will prevent idle UEs from accessing the cell, thereby causing the cell to become non-cell defined. Therefore, the ideal method is to optimize the transmission for future 6G, such as transmitting the system message only when needed.

[0046] A cell can be in different states, including an off state, a basic mode state, and an active mode state. The off state allows the cell to shut down most of the hardware, and in this state, the cell does not receive nor transmit any signal / channel. In the basic state, the cell periodically transmits a discovery signal, while all other signals or channels are transmitted in an on-demand manner. Therefore, the always-on signal is limited to the discovery signal, thereby enabling the network device to save energy. The active mode state refers to the cell having normal communication functions, including that the cell will often transmit system messages on the signal channel and the like.

[0047] As shown in FIG. 2, in a 6G (Sixth Generation) system, a cell can have the three states and change from one state to another. In order to save network energy, when there is no UE activity, for example, at night or in an office area, the cell can enter the off state. However, when there is UE activity but the activity is not frequent, the cell can enter the basic mode. When there are more active UEs, the cell can change to the active mode.

[0048] The basic mode can be a low-power mode of the cell, and part of the downlink broadcast channel, for example, a system message, can be turned off. However, it will continuously transmit a discovery signal / synchronization signal to ensure good network coverage. The off mode allows the network to completely turn off the downlink transmission, including the discovery signal / synchronization signal, to enable the network to enter a deeper power saving state. As shown in FIG. 3, in the related art, there is a method for waking up a cell in the off mode, and a UE wakes up a cell in the off mode by transmitting an on-demand signal.

[0049] However, there is a problem of how to ensure the mobility of a UE after the UE camps on a cell. If the cells around the camped cell are also in the off mode, the UE cannot complete the mobility measurement and cell reselection. In order to solve this problem, the present application provides a mobility measurement method that can simultaneously consider the energy saving of the network and implement the mobility measurement and cell reselection of the UE.

[0050] Please refer to FIG. 4, which shows a flowchart of a mobility measurement method provided by an embodiment of the present application. The method is executed by a terminal device. The method includes the following step 410.

[0051] Step 410: The terminal device transmits a first reference signal and / or first information on a first resource, and the first reference signal and / or first information are used for a first network device to perform mobility measurement on the terminal device.

[0052] Correspondingly, the first network device receives the first reference signal and / or first information on the first resource.

[0053] Optionally, the first network device serves the first cell, and the first cell is a cell where the terminal device currently resides.

[0054] Optionally, assuming a scenario as shown in FIG. 5, a terminal device in an RRC (Radio Resource Control) idle state resides in cell 1, at this time, cell 1 sends a synchronization measurement signal for normal residence of the terminal device. Meanwhile, the surrounding neighbor cells 2 and 3 turn off the transmission of the synchronization measurement signal for network energy saving because no terminal device resides therein.

[0055] As shown in FIG. 6, when a terminal device in an RRC idle state needs to perform cell reselection due to movement, first, the terminal device needs to determine whether there is a need for cell reselection, which can be determined according to conditions, for example, when the terminal device measures a signal energy in the currently residing cell to be lower than a threshold, the terminal device can determine that there is a need for cell reselection.

[0056] Optionally, the terminal device, in a case where it is determined that cell reselection is needed, transmits the first reference signal and / or the first information on the first resource.

[0057] Optionally, the first resource is a periodic resource. Optionally, the first resource is a periodic time-frequency domain resource. Optionally, the terminal device periodically transmits the first reference signal and / or the first information on the first resource.

[0058] Optionally, the first reference signal is a sequence-based reference signal. Illustratively, the first reference signal includes at least one of the following: a PRACH (Physical Random Access Channel), an SRS (Sounding Reference Signal), and an OOK (On-Off Keying) signal. For example, the first reference signal is a random access preamble carried in the PRACH.

[0059] The PRACH is a physical channel used by the terminal device to send a random access preamble to the network device, which is part of the random access process, and is used for the terminal device to request network resources or resynchronize.

[0060] The SRS is a reference signal for uplink channel estimation, which helps the network device to understand the frequency domain information of the uplink channel, perform frequency selective scheduling, and downlink beamforming.

[0061] OOK is a special case of ASK (Amplitude Shift Keying) modulation, taking one amplitude as 0 and the other as non-0, which is OOK. Binary on-off keying (OOK) is also known as binary amplitude shift keying (2ASK), which is to control the opening and closing of the sinusoidal carrier by using a single polarity non-return-to-zero code sequence.

[0062] Optionally, the first information is carried in a PUSCH (Physical Uplink Shared Channel). Optionally, the first information includes identification information of the terminal device. Illustratively, the first information includes a UE ID (Identification) of the terminal device.

[0063] Optionally, the first network device performs mobility measurement on the terminal device based on the first reference signal and / or the first information. Illustratively, the first network device measures the signal quality of the first reference signal, and determines whether the terminal device needs to perform cell reselection based on the signal quality of the first reference signal.

[0064] Optionally, the first network device can send related information of the first reference signal and / or the first information to a second network device, and the second network device performs mobility measurement on the terminal device. Optionally, the second network device serves a second cell, and the second cell is a neighboring cell of the first cell. Optionally, the first network device and the second network device can be the same network device or different network devices, which are not limited in the present application. If the first network device and the second network device are the same network device, no information interaction is needed between the first network device and the second network device. If the first network device and the second network device are different network devices, the first network device and the second network device can interact through an interface between network devices or through a core network element. The first network device can send the related information of the first reference signal and / or the first information to the second network device through the interface between network devices or the core network element, and the second network device can perform mobility measurement on the terminal device based on the related information of the first reference signal and / or the first information.

[0065] The technical scheme provided by the embodiments of the present application is that the network device performs mobility measurement on the terminal device, without the terminal device performing mobility measurement, which realizes energy saving of the terminal device. At the same time, the network device does not need to send a synchronization measurement signal, but performs mobility measurement, which realizes energy saving of the network device.

[0066] Regarding the first reference signal and / or the first information

[0067] 1. Configuration information of the first reference signal and / or configuration information of the first information

[0068] Optionally, the configuration information of the first reference signal and / or the configuration information of the first resource is configured by the first network device. Optionally, the first resource is related to a first cell. The first cell is a cell where the terminal device currently camps on.

[0069] Optionally, the configuration information of the first reference signal and / or the configuration information of the first resource is configured through random access information in a random access procedure. In an example, the configuration information of the first reference signal and / or the configuration information of the first resource is configured through RAR / Msg2. Illustratively, the terminal device triggers a four-step random access procedure, and the first network device carries the configuration information of the first reference signal and / or the configuration information of the first resource in the RAR / Msg2. In another example, the configuration information of the first reference signal and / or the configuration information of the first resource is configured through Msg4. Illustratively, the terminal device triggers a four-step random access procedure, and the first network device carries the configuration information of the first reference signal and / or the configuration information of the first resource in the Msg4. In another example, the configuration information of the first reference signal and / or the configuration information of the first resource is configured through MsgB. Illustratively, the terminal device triggers a two-step random access procedure, and the first network device carries the configuration information of the first reference signal and / or the configuration information of the first resource in the MsgB.

[0070] Optionally, the configuration information of the first reference signal and / or the configuration information of the first resource is configured through control signaling. Illustratively, the terminal device is in an RRC connected state, and the first network device can indicate the configuration information of the first reference signal and / or the configuration information of the first resource through downlink control signaling. Illustratively, the first network device can indicate the configuration information of the first reference signal and / or the configuration information of the first resource through DCI, or can provide RRC signaling to indicate the configuration information of the first reference signal and / or the configuration information of the first resource.

[0071] Optionally, the configuration information of the first reference signal and / or the configuration information of the first resource is predefined. Optionally, the configuration information of the first reference signal and / or the configuration information of the first resource is preconfigured.

[0072] Optionally, the first reference signal and / or the first information are used to wake up a first cell, and the first cell is a cell where the terminal device currently camps on and / or a neighboring cell of the cell where the terminal device currently camps on. Optionally, the first cell is in an off state, and after receiving the first reference signal and / or the first information, the first cell switches to a basic mode state or an active state.

[0073] 2、Example embodiment

[0074] As shown in FIG. 6, when a UE in RRC idle state needs to do cell reselection due to movement, the UE first needs to determine whether there is a need for cell reselection. Here, the determination can be made according to conditions, for example, when the signal energy measured by the UE in the current camped cell is lower than a threshold, the UE can determine that there is a need for cell reselection.

[0075] At this time, the UE transmits the first reference signal and / or the first information on the first resource, where the first resource includes a periodic time-frequency domain resource. When the first resource is a periodic resource, the UE periodically transmits the first reference signal and / or the first information on the first resource. Here, the first reference signal can be a sequence-based reference signal, such as PRACH, SRS, or an OOK signal. The first information can include UE ID information. The sequence configuration information of the first reference signal can be provided by the base station in pre-configuration or pre-definition. The sequence configuration information of the first reference signal and / or the configuration information of the first resource can be included in the feedback information received by the UE after transmitting the ON-DEMAND signal.

[0076] The first reference signal transmitted by the UE can enable the base station to make measurements based on the first reference signal, and the current camped cell can instruct the surrounding neighbor cells to measure the first reference signal on the first resource, so that the UE can be selected to continue camping in the current cell or to switch to a new cell based on the measurement results. The advantage here is that the UE can save the power consumption that would otherwise be required for UE measurement, which is more energy-efficient for the UE. At the same time, the neighbor cells can complete the mobility measurement of the UE without sending synchronization measurement signals, which is more energy-efficient for the base station.

[0077] Through the above method, the terminal device can obtain the configuration information of the first reference signal and / or the configuration information of the first information, so that the terminal device can trigger the first network device to perform mobility measurement on the terminal device.

[0078] Regarding cell switching

[0079] Optionally, the method further includes the following step 420 (not shown in the figure).

[0080] Step 420, the terminal device receives second information on a second resource, and the second information is related to a second cell.

[0081] Correspondingly, the network device transmits the second information on the second resource.

[0082] 1. The second resource

[0083] Optionally, the second resource is configured by the first network device and is related to the first cell, which is the cell where the terminal device currently camps. Optionally, the configuration information of the second resource is carried in the same information as the configuration information of the first resource. For example, the first network device configures the configuration information of the second resource through system messages. Optionally, the first network device configures the configuration information of the second resource through RRC signaling. Optionally, the first network device configures the configuration information of the second resource through random access messages during the random access process. For example, the first network device carries the configuration information of the second resource in the RAR (Random Access Response).

[0084] Optionally, the second resource is determined based on its association with the first resource. Optionally, the association between the second resource and the first resource is configured by the first network device. Optionally, the configuration information of the first resource carries the association between the second resource and the first resource. Optionally, the association between the second resource and the first resource refers to the offset information between the first resource and the second resource. For example, the association between the first resource and the second resource is the time-domain offset and / or frequency-domain offset between the first resource and the second resource.

[0085] Optionally, the second resource is used to transmit second information. For example, the second resource is a PDSCH resource used to carry the transmission of the second information.

[0086] Optionally, the second resource is used to transmit scheduling information for the second information. For example, the second resource is a PDCCH (Physical Downlink Control Channel) retrieval space, and the first network device transmits DCI (Downlink Control Information) for scheduling the second information on the second resource. Alternatively, the first network device transmits a PDCCH on the second resource, which carries the DCI for scheduling the second information.

[0093] identification information of the second cell;

[0094] system information of the second cell.

[0095] Exemplarily, as shown in FIG. 7, after the terminal device sends the first reference signal and / or the first information to the first network device, the first network device measures the first reference signal, and meanwhile, the first network device can inform the second network device to measure the first reference signal. After the first network device and / or the second network device complete the measurement of the first reference signal, the first network device sends second information to the terminal device, and the second information can carry relevant information of the second cell. Exemplarily, if the terminal device needs to be switched to the second cell, then the second information can carry at least one of the frequency domain information of the synchronization signal of the second cell, the time domain information of the synchronization signal of the second cell, the identification information of the second cell, and the system information of the second cell. Exemplarily, if the terminal device does not need to be switched to the second cell, then the second information can only carry indication information that the terminal device does not need to be switched to the second cell.

[0096] 3. Switching to the second cell

[0097] Optionally, the terminal device searches for the second cell according to the second information, and camps on the second cell.

[0098] Optionally, the method further includes the following step 430 (not shown in the figure).

[0099] Step 430: The terminal device sends a second reference signal and / or third information through a third resource, and the second reference signal and / or the third information are used for the terminal device to confirm that the switching to the second cell is completed.

[0100] Correspondingly, the second network device receives the second reference signal and / or the third information. The second network device provides services for the second cell. Optionally, the first network device can also receive the second reference signal and / or the third information to confirm that the terminal device is switched to the second cell.

[0101] Optionally, the configuration information of the second reference signal and / or the configuration information of the third resource are configured by the first network device. Exemplarily, the configuration information of the second reference signal and / or the configuration information of the third resource are configured by the same method as the configuration information of the first reference signal and / or the configuration information of the first resource. For this, reference can be made to the above description of the configuration information of the first reference signal and / or the configuration information of the first resource in the above embodiments, and the present application will not be repeated here.

[0102] Optionally, the second information carries configuration information of the second reference signal and / or configuration information of the third resource. For example, the system message of the second cell carries configuration information of the second reference signal and / or configuration information of the third resource. For example, the second reference signal includes PRACH, and the system message of the second cell carries PRACH configuration information.

[0103] Optionally, the configuration information of the second reference signal and / or the configuration information of the third resource are configured by the second network device. Optionally, if the second information does not carry information about the second cell, the terminal device searches for the second cell and receives system messages broadcast by the second cell to obtain relevant information about the second cell. The relevant information about the second cell may include the configuration information of the second reference signal and / or the configuration information of the third resource.

[0105] Optionally, the third information is carried in the PUSCH. Optionally, the third information can be a random access message in the random access procedure. For example, the third information can be Msg3 or MsgA.

[0106] Optionally, the third information includes at least one of the following:

[0107] Identification information of the terminal device;

[0108] Instructions for the terminal device to switch to the second cell.

[0109] 4. Exemplary Embodiment

[0110] As shown in Figure 7, after the UE sends the first reference signal and / or the first signal, the UE receives the second information in the second resource. Here, the second resource can be the PDCCH retrieval space, where the currently camped cell (first cell) sends PDCCH to schedule channel transmission carrying the second information. Optionally, the second resource can also be used to transmit channel transmission carrying the second information. The second resource can be obtained through configuration by the currently camped cell, or it can be obtained through its relative position to the first resource. The second information includes information about whether a cell handover is needed, and / or the frequency information of the synchronization signal of the target cell (second cell), and / or the time domain information of the synchronization signal of the target cell, and / or the cell index information of the target cell, and / or the system message of the target cell.

[0111] The UE searches for the target cell according to the second information. If the second information does not include the system information of the target cell, the UE needs to acquire the system information of the target cell. Then, the UE sends the second reference signal and / or the third information to the target cell on the third resource. The third resource can be configured by the system information of the target cell. The second signal includes a PRACH. The third information can be carried by a PUSCH. The PUSCH can include a MSG3. The third information includes a UE ID and / or information related to the completion of the camping on the target cell by the UE. That is, when the target cell receives the second reference signal and / or the third information, the second network device can determine that the UE has completed the cell switching or has camped on the target cell. When the second network device receives the third information, the second network device can determine that the UE has completed the cell switching and the operation of the mobility measurement. Thus, the original camping cell (the first cell) can determine whether to switch to the off state based on its own situation. As shown in FIG. 8, whether to close the synchronization signal of the first cell can be determined based on whether there is another UE camping on the first cell, thereby achieving network energy saving.

[0112] Through the above method, after the first network device completes the mobility measurement for the terminal device, the terminal device can be notified to perform cell switching, without the terminal device itself performing the mobility measurement, and without the neighboring cell of the first cell sending the synchronization measurement signal, thereby achieving energy saving of the terminal device and the network device.

[0113] Whether to perform the mobility measurement for the terminal device by the first network device

[0114] 1. The first network device indicates whether to perform the mobility measurement for the terminal device by the first network device

[0115] Optionally, the first network device configures whether to perform the mobility measurement for the terminal device by the first network device for the terminal device. For example, the system information of the first cell carries the indication information indicating whether to perform the mobility measurement for the terminal device by the first network device. Optionally, the system information of the first cell includes the first indication information, and the first indication information is related to the mobility measurement performed by the first network device for the terminal device.

[0116] Optionally, if the first indication information indicates that the mobility measurement is performed for the terminal device by the first network device, the terminal device performs the step 410.

[0117] Optionally, if the first indication information indicates that the mobility measurement is performed on the terminal device by the first network device, and the terminal device is in the RRC idle state or the RRC inactive state, the terminal device switches to the RRC connected state to obtain the configuration information of the first reference signal and / or the configuration information of the first resource. Illustratively, the terminal device switches to the RRC connected state and receives the configuration information of the first reference signal and / or the configuration information of the first resource sent by the first network device.

[0118] Optionally, if the first indication information indicates that the mobility measurement is performed on the terminal device by the first network device, the terminal device triggers a random access procedure to obtain the configuration information of the first reference signal and / or the configuration information of the first resource. Illustratively, if the RRC link recovery of the terminal device fails, the terminal device triggers a RACH (Random Access Channel) procedure. The first network device can configure the configuration information of the first reference signal and / or the configuration information of the first resource through a random access message in the random access procedure. Illustratively, the first network device configures the configuration information of the first reference signal and / or the configuration information of the first resource through RAR and / or Msg4.

[0119] Optionally, if the first indication information indicates that the mobility measurement is not performed on the terminal device by the first network device, the terminal device performs a cell reselection method provided in the related art. Illustratively, the terminal device measures a synchronization measurement signal sent by a neighbor cell of the first cell to determine a target cell to be switched.

[0120] Optionally, the first network device indicates whether the mobility measurement is performed on the terminal device by the first network device through a paging message. Illustratively, the terminal device receives a paging message, and the paging message is related to the mobility measurement performed on the terminal device by the first network device. Illustratively, the paging message contains a first bit, and a value of the first bit is a first value, indicating that the mobility measurement is performed on the terminal device by the first network device, and a value of the first bit is a second value, indicating that the mobility measurement is not performed on the terminal device by the first network device.

[0121] Optionally, the above example illustrates whether the first network device performs mobility measurement on the terminal device by explicitly indicating whether the system message and / or paging message of the first cell perform mobility measurement on the terminal device. The system message and / or paging message of the first cell can also implicitly indicate whether the first network device performs mobility measurement on the terminal device. For example, if the system message of the first cell contains a first SIB (System Information Block), it indicates that the first network device performs mobility measurement on the terminal device; if the system message of the first cell does not contain a first SIB, it indicates that the first network device does not perform mobility measurement on the terminal device. For example, the resources occupied by the paging message are associated with whether the first network device performs mobility measurement on the terminal device; this association can be configured by the first network device or predefined or preconfigured.

[0122] 2. The first network device performs mobility measurement on the terminal device, then switches to a system where the first network device does not perform mobility measurement on the terminal device.

[0123] For ease of description, the following will refer to the first mechanism as the one in which the first network device performs mobility measurement on the terminal device, and the second mechanism as the one in which the first network device does not perform mobility measurement on the terminal device.

[0124] Optionally, the first network device may instruct the terminal device to switch from the first mechanism to the second mechanism. For example, the first network device may use dedicated instruction information to indicate the switch between the first and second mechanisms.

[0125] For example, if the first network device indicates whether to perform mobility measurement on the terminal device via a system message from the first cell, then the handover between the first mechanism and the second mechanism can be indicated by updating information via system messages. For example, the first network device indicates the handover between the first mechanism and the second mechanism via a paging message.

[0126] For example, the terminal device receives a paging message related to mobility measurement performed on the terminal device by the first network device. A reversal of the first indication information means that the first indication information is reversed from indicating a first mechanism to indicating a second mechanism, or vice versa. Optionally, the paging message is used to indicate a system message update for the first cell.

[0127] 3. Exemplary Embodiment

[0128] The first network device can select a mechanism of mobility measurement (first mechanism) and UE cell reselection (second mechanism), for example, the first network device can select that the UE performs mobility measurement based on measuring synchronization measurement signals of the first cell and neighboring cells, and implements cell reselection (first mechanism). Or the first network device can select to implement the mobility measurement and cell reselection mechanism for the UE based on the first reference signal sent by the UE (second mechanism).

[0129] When in the first mechanism and the first network device wants to switch to the second mechanism, the first network device needs to first notify the UE residing in the first cell of the switching. One method is that the first network device notifies the UE to update the system message through a paging message, and notifies the UE to switch from the first mechanism to the second mechanism in the system message. Alternatively, at this time the UE needs to enter the RRC connected state. After entering the RRC connected state, the first network device configures the configuration information of the first resource and / or the configuration information of the first reference signal for each UE. Alternatively, the UE initiates a RACH process, and the first network device can configure the configuration information of the first resource and / or the configuration information of the first reference signal for each UE through RAR and / or Msg4. When in the second mechanism and the first network device wants to switch to the first mechanism. The first network device notifies the UE to update the system message through a paging message, and notifies the UE to switch from the second mechanism to the first mechanism in the system message.

[0130] Through the above method, the terminal device can switch between the first mechanism and the second mechanism. The first mechanism can achieve energy saving of the terminal device and the network device, and the second mechanism can ensure the stability of cell switching.
