All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the examples and figures of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Fig. 1 is a diagram illustrating an application scenario of a cell camping method according to an embodiment. As shown in fig. 1, a communication connection is established between the terminal device 10 and the network device, alternatively, the terminal device 10 and the network device may establish a communication connection through a fourth generation communication technology, a fifth generation communication technology, and the like, and a communication connection manner of the terminal device and the network device is not limited in this embodiment of the application. The network device may include an access network device 20, and one or more core network devices 30 in communication with the access network device 20.

In some embodiments, the terminal device 10 may be referred to as a User Equipment (UE). The terminal device may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like, and may also be a mobile phone, a Mobile Station (MS), a terminal device (mobile terminal), a notebook computer, or the like, and the terminal device 10 may communicate with one or more core networks through a Radio Access Network (RAN). The terminal equipment 10 may be, for example, a mobile telephone (or so-called "cellular" telephone) or a computer with terminal equipment, etc., and the terminal equipment 10 may also be, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with the radio access network. The terminal device 10 may also be a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a network evolved in the future, and the like, and the implementation of the present application is not limited.

The access network device 20 may be a long-term evolution (LTE) system, a New Radio (NR) system, or an evolved base station (evolved Node B, which may be referred to as eNB or e-NodeB for short) macro base station, a micro base station (also referred to as a "small base station"), a pico base station, an Access Point (AP), a Transmission Point (TP), or a new generation base station (new generation Node B, NodeB) in an authorized assisted access long-term evolution (LAA-LTE) system.

In the embodiment of the present application, for a SA network architecture of 5G, the access network device 20 may be a gnnodeb of an NR system, and the Core network device 30 communicating therewith may be a Next Generation Core (NGC) device. When the access network device is a base station of an LTE system, the Core network device 30 that performs communication may be an Evolved Packet Core (EPC).

In the related art, the SA network of 5G is used as a new network standard, the network device configures a high priority to the NR cell adopting the SA network architecture, and the terminal device preferentially selects the NR cell to camp on in the SA mode. However, the power consumption of the terminal device in communication through the NR cell is much larger than that in communication through the LTE cell, which causes a problem that the power consumption of the terminal device in the SA mode is high, and the endurance is poor.

In the embodiment of the present application, a cell camping method, an apparatus, a terminal device, and a computer-readable storage medium are provided, so that by reducing a reselection priority corresponding to an NR cell adopting an SA network architecture, the terminal device is camped in an LTE cell in an SA mode, power consumption of the terminal device in the SA mode can be reduced, and a cruising ability of the terminal device is improved.

As shown in fig. 2, in an embodiment, a cell camping method is provided, which may be applied to the terminal device described above, and the method may include the following steps:

and step 210, when the use state of the terminal device meets the trigger condition, reducing the reselection priority corresponding to the new air interface NR cell from the first reselection priority to a second reselection priority.

A cell, also called a cell, refers to an area covered by a base station or a part of a base station (e.g. a sector antenna, etc.) in a cellular mobile communication system, and terminal devices in the covered area can communicate with the base station through a wireless channel. Alternatively, the NR cell in this embodiment may be an NR cell accessed by a terminal device supporting the SA mode, and the NR cell may refer to an area covered by a 5G base station adopting an SA network architecture (i.e., a 5G base station communicating with a 5G core network). In the SA mode, the terminal device can communicate only through a single mobile network, for example, the terminal device is connected to only the NR network of 5G or only the LTE network of 4G, while in the NSA mode, the terminal device can be connected to both the NR network of 5G and the LTE network of 4G, and communicate through the NR network and the LTE network.

In some embodiments, after the terminal device is powered on, a Public Land Mobile Network (PLMN) may be selected for registration, and after the registration is successful, a cell is selected from the registered PLMN for camping, so that the terminal device receives a service through the camped cell. In the SA mode, the terminal device may select only an NR cell or an LTE cell to camp on. Optionally, when the terminal device selects a cell to camp on, the terminal device may first perform cell search, and the terminal device may obtain time and frequency synchronization with each detected cell, thereby obtaining a physical identifier of each cell, and may obtain parameters (such as signal quality) of each cell according to the physical identifier to select a suitable cell to camp on.

After the terminal equipment normally resides in one cell, one cell can be reselected for residence. Different types of cells may correspond to different reselection priorities, where the types of cells may include, but are not limited to, LTE cells, NR cells based on SA network architecture, NR cells based on NSA network architecture, which refers to an area covered by a 5G base station in communication with a 4G core network, and the like. In the related art, since the SA network of 5G belongs to a newer network standard, the NR cell based on the SA network architecture is generally configured to have a high priority, and if the searched selectable cells include the NR cell based on the SA network architecture, the reselection priority of the NR cell is higher than that of the LTE cell, and when the terminal device performs cell reselection, the terminal device is easy to reselect to the NR cell and camp on the NR cell.

In the embodiment of the present application, the use state of the terminal device may be monitored, and when the use state of the terminal device satisfies the trigger condition, the reselection priority corresponding to the NR cell based on the SA network architecture is reduced. The usage status may be used to describe the operation condition of the terminal device, and the usage status may include, but is not limited to, a power status, a required service type, an operating application type, a traffic usage status, a screen usage status, and the like. Wherein, the power state may include a remaining power; the required service type may refer to a type of service required by the terminal device, such as a voice service, a video service, a data transmission service, and the like; the types of applications run may include, but are not limited to, social applications, instant messaging applications, gaming applications, browser applications, and the like; the flow use state can comprise used flow, residual used flow and the like in a preset time period; the screen use state may include a screen-off state, a screen-on state, and the like.

The triggering condition may be set according to an actual requirement, and the triggering condition may be a condition that a requirement of the terminal device for the data service is low, or may be a condition that the terminal device does not currently reside in the NR cell. When detecting that the usage status of the terminal device satisfies the trigger condition, it may be stated that the terminal device does not need to camp on the NR cell or is not suitable for camping on the NR cell. In some embodiments, the condition that the usage state of the terminal device satisfies the trigger condition may include one or more of the following conditions:

(1) the residual capacity of the terminal equipment is lower than the capacity threshold. The power threshold may be set according to an actual requirement, for example, 20%, 30%, and the like, and may monitor the remaining power of the terminal device in real time, and when the remaining power is lower than the power threshold, it may indicate that the power currently available to the terminal device is less, and may control the terminal device to perform a low power consumption mode, and since the terminal device resides in the NR cell, the power consumption of the terminal device may be higher, and the reselection priority corresponding to the NR cell may be reduced.

(2) The type of service required by the terminal device belongs to the configuration type. Optionally, the configuration type may refer to a service type supported by the LTE network, such as a voice service and a general data transmission service, and if the terminal device is camped in the LTE cell and is also capable of receiving a service corresponding to the service type, the terminal device may preferentially camp in the LTE cell.

(3) The remaining usage flow of the terminal device is below the flow threshold. The flow threshold may be set according to actual requirements, for example, 2GB (gigabytes), 2.5GB, and the like. The terminal device may obtain flow use data of the terminal device from a server corresponding to a currently accessed network operator, where the flow use data may include a total flow and an already used flow that can be used within a preset time period (e.g., within 1 month), and then obtain a remaining use flow according to the total flow and the already used flow, where the remaining use flow may be a difference value between the total flow and the already used flow. Optionally, the terminal device may also write the total flow available in the preset time period into the flow monitoring file, monitor the flow usage in real time, count the flow usage for a fixed time period (for example, 12 hours, 24 hours, and the like), and write the flow usage for the fixed time period into the flow monitoring file. When the residual using flow is required to be determined, the residual using flow can be calculated according to the total flow and the flow using condition recorded in the flow monitoring file. When the remaining used traffic is lower than the traffic threshold, it may be indicated that the terminal device currently may use less traffic, and the traffic may be consumed quickly due to the residence in the NR cell, so the reselection priority corresponding to the NR cell may be lowered.

(4) The application type currently operated by the terminal equipment belongs to the target type. The target type may be an application type with a small requirement on the network, and the data service provided by the LTE network can meet the operation requirement of the application of the target type. Alternatively, the target type may be an application type with less network requirements, such as a social application, a browser application, a reading application, and the like, but is not limited thereto. When the currently running application type belongs to the target type, the terminal equipment is resided in the LTE cell without influencing the normal running of the application, and then the terminal equipment can be preferentially resided in the LTE cell.

It should be noted that the above trigger conditions are not limited to the ones described in the above embodiments, and other trigger conditions may also be available, for example, the terminal device is in the screen-off state, and the use state and the trigger conditions of the terminal device are not limited herein.

As a specific embodiment, when the usage status of the terminal device satisfies the trigger condition, the reselection priority corresponding to the NR cell may be reduced from the first reselection priority to a second reselection priority, and the priority parameter corresponding to the NR cell may be configured as the second reselection priority. The first reselection priority may be higher than the third reselection priority corresponding to the LTE cell, and the second reselection priority may be lower than the third reselection priority corresponding to the LTE cell, for example, if the reselection priority corresponding to the LTE cell is 6, the second reselection priority may be 4, 5, and so on.

In some embodiments, the reselection priority of the cell may include an absolute priority and a dedicated priority, where the absolute priority may be set by the network through a parameter CellReselPriority, and is sent to the terminal device in a cell broadcast through a system message. The dedicated priority is generated directly by the network device through a dedicated priority algorithm in the system when the terminal device releases Radio Resource Control (RRC) Connection, and is issued to the terminal device through an RRC Connection Release message. The dedicated priority parameter corresponding to the NR cell may be configured as the target priority described above, or a priority parameter different from the absolute priority and the dedicated priority may be set, and the priority parameter may be configured as the target priority described above.

Step 220, the control terminal device resides in the LTE cell in the independent networking SA mode.

The terminal equipment can only select an LTE cell or an NR cell to reside in an SA mode, when the terminal equipment reselects a cell, if the cell searched by the terminal equipment simultaneously comprises the NR cell and the LTE cell, the NR cell and the LTE cell can be different system cells, and because the reselection priority reduced by the NR cell is the second reselection priority and is lower than the third reselection priority corresponding to the LTE cell, the terminal equipment can reside in the LTE cell with higher reselection priority and can not select the NR cell to reside.

In some embodiments, when the terminal device performs cell reselection, the configured priority parameter may be preferentially used, and a camped cell may be selected according to the configured priority parameter. When the terminal device reselects the cell, it can first judge whether the priority parameter of the NR cell based on the SA network architecture is configured, and if so, it can discard the priority information (including the absolute priority and the dedicated priority) sent by the network device, and select the resident cell based on the configured priority parameter. Further, if the terminal device currently resides in the LTE cell, since the configured priority parameter is the second reselection priority and is smaller than the reselection priority corresponding to the LTE cell, the terminal device may continue to reside in the LTE cell with a higher reselection priority. If the terminal equipment is currently resident in the NR cell, the configured priority parameter is the second reselection priority and is smaller than the reselection priority corresponding to the LTE cell, so that the terminal equipment can select the LTE cell with higher reselection priority to be resident.

When the terminal device reselects the cell, if the priority parameter of the NR cell based on the SA network architecture is not configured, the camped cell may be selected based on the priority information issued by the network device, and the cell with the highest priority may be selected for camping.

It should be noted that, when the terminal device performs cell reselection, if the searched cell only includes an NR cell, the configured priority parameter, the priority information issued by the network device, and the like may not be considered, because the reselection priorities corresponding to the NR cells may be the same. In this case, the target NR cell to camp on may be selected directly according to the signal qualities of the currently camped NR cell and the neighboring NR cells.

Alternatively, the Signal quality of the currently camped NR Cell may be measured, and may be the sum of a Reference Signal Receiving Power (RSRP) value of the currently camped NR Cell and a Reselection Hysteresis value (CRH), which may be configured by the network device. The signal quality of each neighboring NR Cell may be measured, and the signal quality of the neighboring NR Cell may be a difference between an RSRP value of the neighboring NR Cell and a configured neighbor reselection Offset (CRO). If the signal quality of the adjacent NR cell is higher than that of the currently resided NR cell, the adjacent NR cell with the highest signal quality can be directly selected as the target NR cell to camp on. Alternatively, if the signal quality of the currently camped NR cell is greater than the quality threshold, the currently camped NR cell may also be camped on directly without performing measurement on the neighboring cells.

When the terminal device reselects the cell, if the searched cell only includes the LTE cell, the target LTE cell can be directly selected to camp according to the signal quality of the currently camped LTE cell and the signal quality of the neighboring LTE cell without considering the configured priority parameter, the priority information issued by the network device, and the like. The LTE cell camping selection method may be the same as the NR cell camping selection method, and is not described herein again.

In the embodiment of the application, when the use state of the terminal device meets the trigger condition, the reselection priority corresponding to the NR cell is reduced from the first reselection priority to a second reselection priority, where the second reselection priority is lower than a third reselection priority corresponding to the LTE cell, and when the terminal device performs cell reselection, because the reselection priority of the NR cell is lower than the reselection priority of the LTE cell, the LTE cell is preferentially selected to camp on the terminal device, so that the terminal device is camped on the LTE cell in the SA mode, and the terminal device is restrained from camping on the NR cell, which can reduce power consumption of the terminal device in the SA mode and improve cruising ability of the terminal device. And the reselection priority corresponding to the NR cell is reduced at a proper time, so that the normal use of the terminal equipment is not influenced, and the requirements of users are met better.

As shown in fig. 3, in an embodiment, another cell camping method is provided, which is applicable to the terminal device described above, and the method may include the following steps:

step 302, when the use state of the terminal device meets the trigger condition, reducing the reselection priority corresponding to the new air interface NR cell from the first reselection priority to a second reselection priority.

The description of step 302 may refer to the related description of step 210 in the above embodiments, and is not repeated herein.

Step 304, in the SA mode, if the terminal device is in an idle state and the searched cells include both an NR cell and an LTE cell, then the LTE cell is selected to camp on.

The terminal device being in an idle state may refer to a state where the terminal device does not establish RRC connection with the wireless network, and the terminal device being in the idle state may perform operations such as cell search, cell selection, and cell reselection. After the terminal equipment is started, the terminal equipment searches the cells and can record the detected physical identifications and cell information of each cell in a cell list. When the terminal device is in an idle state and performs cell reselection, the physical identifier and cell information of each searched cell can be obtained from the cell list, and the cell type of each cell can be determined according to the cell information. If the NR cell and the LTE cell based on the SA network architecture are recorded in the cell list at the same time, it is determined that the searched cells include both the NR cell and the LTE cell, and the NR cell and the LTE cell may be neighbor cells of different systems. If the terminal device configures the priority parameter of the NR cell based on the SA network architecture before the cell reselection, that is, the reselection priority corresponding to the NR cell is reduced from the first reselection priority to the second reselection priority, and since the second reselection priority is lower than the third reselection priority corresponding to the LTE cell, the terminal device may select the LTE cell residing in the LTE cell with the higher reselection priority according to the second reselection priority and the third reselection priority when performing reselection.

In some embodiments, if the terminal device is camped on the LTE cell and is in an idle state, camping on the LTE cell may be continued according to the second reselection priority and the third reselection priority. When the terminal device is in an idle state and performs cell reselection, if the terminal device currently resides in an LTE cell, the terminal device may continue to select to reside in the LTE cell without switching to an NR cell to reside because the reselection priority of an NR cell adjacent to the currently residing LTE cell is lower than the reselection priority of the LTE cell.

As an optional implementation manner, if the terminal device resides in an LTE cell and is in an idle state, the terminal device may measure an adjacent LTE cell of the currently residing LTE cell to obtain signal quality of each adjacent LTE cell, and optionally, the signal quality may be determined by signal strength, signal frequency point, and the like. If there is a neighboring LTE cell with a signal quality higher than the currently camped LTE cell, the terminal device may select the neighboring LTE cell camped on the LTE cell with the signal quality higher than the currently camped LTE cell. Further, the terminal device may select the neighboring LTE cell with the highest signal quality for camping.

In some embodiments, if the terminal device is camped on the NR cell and is in an idle state, the first target cell may be selected for access according to the second reselection priority and the third reselection priority, where the first target cell is an LTE cell adjacent to the camped NR cell. When the terminal device is in an idle state and performs cell reselection, if the terminal device currently resides in the NR cell, the terminal device may select an adjacent LTE cell of the currently residing NR cell to camp on because the reselection priority of the currently residing NR cell is lower than the reselection priority of the LTE cell.

As an optional implementation manner, if the terminal device resides in the NR cell and is in an idle state, the terminal device may measure the neighboring LTE cells of the currently residing NR cell to obtain the signal quality of each neighboring LTE cell. The terminal device may select the neighboring LTE cell with the highest signal quality for camping.

If the terminal device does not configure the priority parameter of the NR cell based on the SA network architecture before the cell reselection, when the terminal device is in an idle state and performs the cell reselection, a cell with the highest priority may be selected to camp based on priority information of each cell issued by the network device.

In some embodiments, after the reselection priority corresponding to the NR cell is lowered, if a priority recovery condition is satisfied, the reselection priority corresponding to the NR cell may be recovered from the second reselection priority to the first reselection priority. Optionally, if the step meets the priority recovery condition, the step of recovering the reselection priority corresponding to the NR cell from the second reselection priority to the first reselection priority may include steps 306 to 310.

Step 306, acquiring the current service requirement characteristics of the terminal equipment.

After the terminal equipment selects to reside in the LTE cell, RRC connection can be established with the LTE network, and data transmission is carried out. The terminal device can obtain the current service requirement and obtain the service requirement characteristic of the service requirement, and the service requirement characteristic can be used for describing the service required by the terminal device currently. Optionally, the service requirement characteristics may include a service type, a data transmission rate requirement, and the like, where the service type may include a voice service, a video service, and a data transmission service, and the data transmission rate requirement may include a high rate requirement, a medium rate requirement, a low rate requirement, and the like.

In some embodiments, when an application program of a terminal device runs, a service module initiating a service requirement in the application program may be acquired, and a current service requirement characteristic may be determined according to the application program and the service module. The data transfer rate requirements may be different for different applications, e.g., low for browser applications, etc., and high for instant interactive type applications, such as gaming applications. Furthermore, due to the different service modules for initiating the service requirements, the requirements of the required service and data transmission rate are also different.

For example, when the instant messaging application is running, if the service module initiating the service requirement is a voice service module, the type of the required service may be a voice service, and the data transmission rate requirement may be a medium rate requirement, and if the service module initiating the service requirement is a video module, the type of the required service may be a video service, and the data transmission rate requirement may be a high rate requirement. For another example, when an instant interaction type application such as a game application is running, if a service module initiating a service requirement is a game data transmission module, the required service type may be a data transmission service, and a data transmission rate requirement may be a high rate requirement.

Step 308, if the LTE cell where the terminal device resides does not satisfy the communication condition corresponding to the service requirement characteristic, restoring the reselection priority corresponding to the NR cell from the second reselection priority to the first reselection priority.

Whether the LTE cell where the terminal device resides meets the communication condition corresponding to the current service requirement characteristic can be judged, and the communication condition can comprise service provided by the LTE cell, signal quality and the like. If the LTE cell where the terminal device resides can provide the service required by the terminal device currently and the signal quality meets the requirement of the service to be performed on the data transmission rate, it can be determined that the LTE cell where the terminal device resides meets the communication condition corresponding to the service requirement characteristic, and data transmission can be performed directly through the LTE network. If the LTE cell where the terminal device resides cannot provide the service required by the terminal device currently, or the signal quality does not meet the requirement of the performed service on the data transmission rate, it may be determined that the LTE cell where the terminal device resides does not meet the communication condition corresponding to the service requirement characteristic, and the reselection priority corresponding to the NR cell may be restored from the second reselection priority to the first reselection priority, so that the terminal device may select the NR cell to reside, and perform data transmission through the NR network.

In some embodiments, restoring the reselection priority corresponding to the NR cell from the second reselection priority to the first reselection priority may comprise: the configuration of the priority parameter corresponding to the NR cell based on the SA network architecture is cancelled, that is, the priority parameter corresponding to the NR cell configured before is deleted. After the configuration of the priority parameter of the NR cell is cancelled, when the terminal device performs cell reselection, the terminal device may select the NR cell to camp on according to the priority information issued by the network device, and since the priority information issued by the network device is generally that the reselection priority of the NR cell based on the SA network architecture is higher than the reselection priority of the LTE cell, the terminal device may select the NR cell to camp on.

And 310, selecting a second target cell to camp on according to the first reselection priority, wherein the second target cell is an NR cell adjacent to the camped LTE cell.

After the reselection priority corresponding to the NR cell is restored from the second reselection priority to the first reselection priority, when the terminal device is in an idle state and performs cell reselection, since the first reselection priority is higher than the third reselection priority of the LTE cell, an adjacent NR cell of the currently camped LTE cell may be selected to camp on. After the terminal equipment resides in the NR cell, RRC connection may be performed through the NR cell, and data transmission may be performed through the NR network. The normal operation of data service on the terminal equipment can be ensured, and the actual requirements of users can be met.

In some embodiments, if the step satisfies the priority recovery condition, then the step of recovering the reselection priority corresponding to the NR cell from the second reselection priority to the first reselection priority may include: and if the time length from the configuration time exceeds the timing time length, restoring the reselection priority corresponding to the NR cell from the second reselection priority to the first reselection priority.

When the terminal device reduces the reselection priority corresponding to the NR cell, the terminal device may configure the priority parameter corresponding to the NR cell as the second reselection priority, and record a configuration time, which is a time when the priority parameter corresponding to the NR cell is configured as the second reselection priority. The valid duration of the configured priority parameter may be set, and the valid duration is the above-mentioned timing duration, for example, the timing duration may be 2 hours, 3 hours, 1.5 hours, and the like. When the timing duration is exceeded, it can be described that the configured priority parameter of the NR cell is invalid, and then the configuration of the priority parameter corresponding to the NR cell can be cancelled, and the configured priority parameter of the NR cell is deleted, so as to recover the reselection priority corresponding to the NR cell. The effective duration of the reselection priority corresponding to the NR cell is set to accurately control the time of the terminal equipment residing in the LTE cell in the SA mode, so that the cell can be selected to reside more flexibly, and different requirements of a user are met while power consumption is reduced.

In the embodiment of the application, the reselection priority corresponding to the NR cell can be reduced or recovered according to the actual service requirement of the terminal device, so that the terminal device can be ensured to select a proper cell for residence, the power consumption in the SA mode can be reduced, and the cruising ability of the terminal device can be improved.

As shown in fig. 4, in an embodiment, the cell camping method may further include the following steps:

step 402, if there is network anomaly in the NR cell where the terminal device currently resides, reducing the reselection priority corresponding to the NR cell from the first priority to a second reselection priority.

After the terminal equipment resides in the NR cell, if data transmission is required to be performed through the NR network, whether network abnormality exists in the resident NR cell can be detected. Alternatively, the network anomaly may include, but is not limited to, an configuration anomaly of the NR cell, a Random Access (RA) failure rate greater than a failure rate threshold, and the like, wherein the configuration anomaly of the NR cell may include, but is not limited to, an physical cell identification anomaly of the NR cell (e.g., an identification conflict with other cells, and the like), an anomaly of a power parameter of the NR cell (e.g., a reference signal power, and the like), and the like. The random access process is a process in which the terminal device interacts with the RRC layer of the base station through a set of messages, and the management and control of the RRC on the entire protocol stack are realized through such a process. The network abnormality of the NR cell where the terminal device resides may affect normal data transmission of the terminal device, and is not performed by using a service. When the network abnormality of the resident NR cell is detected, the reselection priority corresponding to the NR cell can be reduced.

And step 404, reselecting the LTE cell to camp on.

When the terminal equipment is in an idle state, because the reduced reselection priority of the NR cell is the second reselection priority and is lower than the third reselection priority of the LTE cell, the LTE cell can be selected to reside, and after the terminal equipment is accessed to the LTE network, data transmission is carried out through the LTE network.

In some embodiments, after the terminal device detects that a network anomaly exists in a currently camped NR cell and reduces a reselection priority corresponding to the NR cell, when the terminal device is in an idle state and performs cell reselection, if a searched cell only includes an NR cell but not an LTE cell, the terminal device may measure neighboring NR cells of the currently camped NR cell, and select an NR cell with a best signal quality according to the measured signal quality of each NR cell to camp.

In some embodiments, other scenarios of reducing and restoring the reselection priority corresponding to the NR cell may also be set. For example, a first time period for decreasing the reselection priority corresponding to the NR cell may be set, and when the terminal device is in the first time period, the reselection priority corresponding to the NR cell is the second reselection priority, which may be lower than the third reselection priority corresponding to the LTE cell. For example, 1 to 6 points in the morning of each day may be set as a time period for decreasing the reselection priority corresponding to the NR cell, during which the terminal device may select to camp on the LTE cell, and when the time period ends, the reselection priority corresponding to the NR cell may be restored.

For example, a second time period for recovering the reselection priority corresponding to the NR cell may also be set, and when the terminal device is in the second time period, the reselection priority corresponding to the NR cell is the first reselection priority and may be higher than a third reselection priority corresponding to the LTE cell. For example, 12 to 14 and 19 to 21 points per day may be set as a time period for restoring the reselection priority corresponding to the NR cell, during which the terminal device may choose to camp on the NR cell, and when the time period ends, the reselection priority corresponding to the NR cell may be lowered again.

Optionally, the first time period and the second time period may be set by the user according to actual needs, or may be set according to usage habits of the user, the usage data of the user using the terminal device every day may be adopted, the usage habits of the user are analyzed according to the usage data, the heavy usage time period of the user every day may be set as the second time period for recovering the reselection priority corresponding to the NR cell, the light usage time period of the user every day may be set as the second time period for reducing the reselection priority corresponding to the NR cell, and the like, but the present invention is not limited thereto.

It should be noted that the scenarios of reducing the reselection priority corresponding to the NR cell and recovering the reselection priority corresponding to the NR cell are not limited to the scenarios described in the foregoing embodiments, and the scenarios of reducing the reselection priority corresponding to the NR cell and recovering the reselection priority corresponding to the NR cell are not limited in the embodiments of the present application.

In the embodiment of the application, the network abnormal scene of the NR cell can be identified, the terminal equipment is actively restrained from residing in the NR cell by reducing the reselection priority corresponding to the NR cell, normal service transmission of the terminal equipment can be ensured, the power consumption of the terminal equipment in an SA mode can be reduced, and the cruising ability of the terminal equipment is improved.
