It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. The technical solutions described in the embodiments of the present application can be arbitrarily combined without conflict.
The embodiment of the application provides a cell residence method, which is applied to a terminal. The specific type of the terminal is not limited in this application, and may be any user equipment, for example, a smart phone, a personal computer, a notebook computer, a tablet computer, a portable wearable device, and the like.
It should be noted that, in an embodiment of the present application, a terminal may select a cell from a first cell and a second cell to camp on, where the first cell and the second cell are cells of different network systems, a reselection priority of the first cell is higher than a reselection priority of the second cell, and the specific first cell and the specific second cell are not limited in this embodiment of the present application.
Specifically, in the embodiment of the present application, the first cell is a cell of SA standard, referred to as an SA cell for short, and the second cell is a cell of LTE standard, referred to as an LTE cell for short. Of course, the first cell and the second cell may also be cells of other different types of networks, and the embodiment of the present application is not limited.
Fig. 1 is an application scenario diagram of an exemplary cell camping method according to an embodiment of the present application. As shown in fig. 1, a communication connection is established between the terminal 10 and the network device, alternatively, the terminal 10 and the network device may establish a communication connection through a fourth generation, a fifth generation, and the like communication technology, and a communication connection manner of the terminal 10 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 10 may be referred to as a User Equipment (UE). The terminal 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 (mobile terminal), a notebook computer, or the like, and the terminal 10 may communicate with one or more core networks through a Radio Access Network (RAN). For example, the terminal 10 may be a mobile telephone (or "cellular" telephone) or a computer having a terminal, such as the terminal 10 may be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with a radio access network. The terminal 10 may also be a handheld device with wireless communication capability, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a network evolving in the future, etc., and the implementation of the present application is not limited thereto.
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 a cell adopting the SA standard of the SA network architecture, and the terminal preferentially selects the SA cell to camp on. But the power consumption of the terminal when communicating through the SA cell is much larger than when communicating through the LTE cell.
Fig. 2 is a first flowchart illustrating a cell camping method according to an embodiment of the present application. As shown in fig. 1, in the embodiment of the present application, a cell camping method mainly includes the following steps:
s201, after the terminal resides in the first cell for a first preset time, if the terminal meets a first preset condition, the reselection priority of the first cell is reduced so that the terminal resides in the second cell.
In the embodiment of the present application, after the terminal resides in the first cell for the first preset duration, if the terminal meets the first preset condition, the reselection priority of the first cell is reduced, so that the terminal resides in the second cell.
It should be noted that, in the embodiment of the present application, the first preset time duration is a time duration preset according to actual needs and application scenarios. The specific first preset time period is not limited in the embodiment of the present application.
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 a terminal in the covered area can communicate with the base station through a wireless channel. Optionally, the first cell in this embodiment may be an SA cell, which refers 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 some embodiments, after the terminal 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 receives a service through the camped cell. The terminal may select either the first cell, i.e., the SA cell, or the second cell, i.e., the LTE cell, to camp on. Optionally, when the terminal selects a cell to camp on, the terminal may first perform cell search, and the terminal may obtain time and frequency synchronization with each detected cell, thereby obtaining a physical identifier of each cell, and may obtain parameters (e.g., signal quality, etc.) of each cell according to the physical identifier to select a suitable cell to camp on.
It should be noted that, in the embodiment of the present application, after the terminal normally camps in one cell, one cell may be reselected for camping. Different types of cells may correspond to different reselection priorities, respectively, where the types of cells may include, but are not limited to, LTE cells, SA cells, NR cells, and so on. In the related art, since the SA network of 5G belongs to a newer network standard, the SA cell is generally configured to have a high priority, and if an SA cell in the searched selectable cells is a higher reselection priority than an LTE cell, that is, the SA cell is a first cell and the LTE cell is a second cell, when the terminal performs cell reselection, the terminal is easy to reselect to the first cell and camp on the first cell.
Specifically, in the embodiment of the present application, the first preset condition includes one or more of the following: the use scene belongs to a preset white list scene, a bright screen and an idle mode.
It should be noted that, in the embodiment of the present application, that the terminal is in the idle mode may refer to a state where the terminal does not establish an RRC connection with the wireless network, and the terminal may perform operations such as cell search, cell selection, and cell reselection when the terminal is in the idle mode. After the terminal is started, the terminal searches the cells and can record the detected physical identifiers and cell information of all the cells in the cell list. When the terminal is in the idle mode 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.
It should be noted that, in the embodiment of the present application, a usage scenario of the terminal may be monitored, and when the usage scenario of the terminal belongs to a preset white list scenario, the reselection priority of the first cell is reduced. The usage scenario may be used to describe the operation condition of the terminal, and the usage scenario may include, but is not limited to, a power state, a required service type, an operating application type, a traffic usage state, a screen usage state, 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, 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 preset white list scene can be set according to actual requirements, and can be a scene in which the terminal has a low requirement on the data service, or a scene in which the terminal does not currently reside in the first cell. When detecting that the usage scenario of the terminal belongs to the preset white list scenario, it may be stated that the terminal does not need to camp on the first cell or is not suitable for camping on the first cell. In some embodiments, the usage scenario of the terminal belonging to the preset white list scenario may include one or more of the following situations:
(1) the remaining power of the terminal is lower than the power 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 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 is less, and may control the terminal to perform a low power consumption mode, and since the terminal resides in the first cell and the power consumption of the terminal is higher, the reselection priority of the first cell may be reduced.
(2) The type of service required by the terminal is of the configuration type. Optionally, the configuration type may refer to a service type supported by a network corresponding to the second cell, for example, a voice service and a general data transmission service, and if the terminal is camped in the second cell and is also capable of receiving a service corresponding to the service type, the terminal may preferentially camp in the second cell.
(3) The remaining usage traffic of the terminal is below the traffic threshold. The flow threshold may be set according to actual requirements, for example, 2GB (gigabytes), 2.5GB, and the like. The terminal may obtain flow use data of the terminal 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 between the total flow and the already used flow. Optionally, the terminal 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 has less currently usable traffic, and the reselection priority corresponding to the first cell may be lowered because the traffic may be consumed quickly due to the residence in the first cell.
(4) The application type currently running by the terminal 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 second cell 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 is resided in the second cell without influencing the normal running of the application, and then the terminal can be preferentially resided in the second cell.
It should be noted that, in the embodiment of the present application, the preset white list scenario may be preset according to an actual requirement, and the embodiment of the present application is not limited.
Specifically, in the embodiment of the present application, after the terminal resides in the first cell for the first preset duration, if the terminal is in the idle mode and the usage scenario belongs to the preset white list scenario, the terminal decreases the reselection priority of the first cell, so that the terminal reselects from the first cell to the second cell and resides in the second cell.
For example, in an embodiment of the present application, the first preset duration is 15 minutes, the first cell is an SA cell, the second cell is an LTE cell, the network speed of the terminal when the terminal resides in the SA cell is faster than the network speed of the terminal when the terminal resides in the LTE cell, and after the terminal resides in the SA cell for 15 minutes, if a usage scenario of the terminal belongs to a preset white list scenario: the current network speed is greater than the scene of the preset network speed, namely the current network speed actually exceeds the actual required network speed and is in an idle mode, the terminal can reduce the reselection priority of the SA cell, so that the cell reselection is carried out, the SA cell is switched to the LTE cell to reside, and the power consumption of the terminal is reduced.
It should be noted that, in the embodiment of the present application, after the terminal resides in the first cell for the first preset time, if the terminal meets the first preset condition, the reselection priority of the first cell may be reduced from the first reselection priority to the second reselection priority, where the priority parameter corresponding to the first cell may be configured as the second reselection priority. The first reselection priority may be higher than the third reselection priority corresponding to the second cell, and the second reselection priority may be lower than the third reselection priority corresponding to the second cell, for example, if the reselection priority corresponding to the second cell is 6, the second reselection priority may be 4, 5, and so on.
In some embodiments, the reselection priorities of the cells may include an absolute priority and a dedicated priority, wherein the absolute priority may be set by the network through a parameter CellReselPriority, and is sent to the terminal 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 releases Radio Resource Control (RRC) Connection, and is issued to the terminal through an RRC Connection Release message. The dedicated priority parameter corresponding to the first cell may be configured as the target priority, 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.
It can be understood that, in the embodiment of the present application, the terminal may select the first cell or the second cell to camp on, and when the terminal performs cell reselection, if the cells searched by the terminal include the first cell and the second cell at the same time, the first cell and the second cell are cells of different network systems, and since the reselection priority reduced by the first cell is the second reselection priority and is lower than the third reselection priority corresponding to the second cell, the terminal may camp on the second cell with the higher reselection priority without selecting the first cell to camp on.
In some embodiments, when the terminal 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 reselects the cell, it can first judge whether the priority parameter of the first cell is configured, if so, it can discard the priority information (including absolute priority and special priority) sent by the network device, and select the resident cell based on the configured priority parameter. Further, the terminal currently resides in the first cell, and since the configured priority parameter is the second reselection priority and is smaller than the reselection priority corresponding to the second cell, the terminal can select the second cell with the higher reselection priority to reside in the second cell.
When the terminal reselects the cell, if the priority parameter of the first cell is not configured, the resident cell can be selected based on the priority information issued by the network equipment, and the cell with the highest priority can be selected for resident.
It should be noted that, when the terminal performs cell reselection, if the searched cell only includes the first 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 first cells may be the same. In this case, the target cell may be directly selected to camp on according to the signal quality of the currently camped first cell and the signal quality of the neighboring cell, where the neighboring cell is a cell of the same network system as the first cell.
Alternatively, the Signal quality of the currently camped first Cell may be measured, and the Signal quality of the currently camped first Cell may be a sum of a Reference Signal Receiving Power (RSRP) value of the first Cell and a Reselection Hysteresis value (CRH), which may be configured by the network device. The signal quality of each neighboring Cell may be measured, and the signal quality of the neighboring Cell may be a difference between an RSRP value of the neighboring Cell and a configured Cell Reselection Offset (CRO). If the signal quality of the adjacent cell is higher than that of the first cell which is resident currently, the adjacent cell with the highest signal quality can be directly selected as the target cell to be resident. Optionally, if the signal quality of the currently camped first cell is greater than the quality threshold, the currently camped first cell may also be directly camped on without measuring the neighboring cells.
When the terminal reselects the cell, if the searched cell only includes the second cell, the target cell can be directly selected to reside according to the signal quality of the second cell and the adjacent cell without considering the configured priority parameter, the priority information issued by the network equipment and the like, wherein the adjacent cell is the cell with the same network system as the second cell. The manner of selecting the second cell to camp on may be the same as the manner of selecting the first cell to camp on, and is not described herein again.
It can be understood that, in the embodiment of the present application, after the terminal resides in the first cell for the first preset time, the reselection priority of the first cell is reduced only when the first preset condition is met, that is, the cell residence is actually controlled according to the actual application scenario and the use state of the terminal, so that the cell reselection performed by the terminal at an inappropriate time is suppressed, the resident cell is switched, and the power consumption of the terminal is reduced.
It should be noted that, in this embodiment of the present application, after the terminal camps in the first cell, in order to make the terminal camp in the first cell for the first preset time, the terminal may perform the following steps: and forbidding closing the background search of the first cell and forbidding reducing the reselection priority of the first cell within a first preset time length.
For example, in the embodiment of the present application, the first preset time period is 15 minutes, the first cell is an SA cell, and the terminal may prohibit, after camping on the SA cell, reducing the reselection priority of the SA cell and prohibiting closing the background search of the SA cell within 15 minutes, so as to maintain camping on the SA cell within 15 minutes.
It can be understood that, in the embodiment of the present application, on the premise that the terminal is on the bright screen, and actually, in a scenario where the terminal is normally used, after the terminal camps on the first cell, the terminal is prohibited to decrease the reselection priority of the first cell and to turn off the background search of the first cell for a certain period of time, so that the terminal may continue to search for the first cell for the certain period of time, and since the reselection priority of the first cell is not decreased, the reselection priority of the first cell is higher than the reselection priority of the second cell, the terminal may remain camped on the first cell, thereby avoiding frequent switching of camped cells and reducing power consumption of the terminal.
It should be noted that, in the embodiment of the present application, after the terminal resides in the first cell for the first preset duration, if the terminal does not satisfy the first preset condition, the reselection priority of the first cell may be prohibited from being reduced, and the background search of the first cell may be prohibited from being closed, so that the terminal continues to reside in the first cell.
It should be noted that, in an embodiment of the present application, the first preset condition may include that the usage scenario belongs to a preset white list scenario, and the preset white list scenario may be a scenario different from a preset black list scenario, so that the terminal does not satisfy the first preset condition, and may specifically be that the usage scenario is in the preset black list scenario. The blacklist scenario may include one or more of the following: the method comprises the steps of starting a wireless network hotspot, presetting an application to foreground operation, having poor network transmission quality and large time delay corresponding to a second cell, being connected with a wireless access point, starting, flying mode, inserting a card, switching a data card for 5min, starting a network corresponding to a first cell by a telephone, sleeping deeply and not starting a data network, and the like.
It can be understood that, in the embodiment of the present application, the preset blacklist scenario is a scenario to which the user is relatively sensitive, and when the usage scenario of the terminal belongs to the preset blacklist scenario, the user generally does not want to perform the camping cell handover, so after the terminal passes through the first preset time period, if the usage scenario is the preset blacklist scenario, it is prohibited to continue to reduce the reselection priority of the first cell, and to stop closing the background search of the first cell, so that the terminal may be prompted to continue camping on the first cell. The preset blacklist scene is only some optional exemplary scenes provided, and a specific preset blacklist scene may be set according to actual requirements, which is not limited in the embodiment of the present application.
And S202, after the terminal resides in the second cell for a second preset time, if the terminal meets a second preset condition, recovering the reselection priority of the first cell.
In the embodiment of the present application, after the terminal resides in the second cell for the second preset duration, if the terminal meets the second preset condition, the reselection priority of the first cell is recovered.
Specifically, in the embodiment of the present application, the terminal may determine the second preset time period by performing the following steps: acquiring the reselection times from a first cell to a second cell between a target moment and a current moment; the target moment is the moment when the terminal switches from screen-off to screen-on for the last time before the current moment, or the moment when the terminal switches from the flight mode to the normal mode for the last time; and determining a second preset time length based on the times and the preset unit time length.
It should be noted that, in the embodiment of the present application, a preset unit time length is set in the terminal, and the preset unit time length may be specifically preset according to actual needs and application scenarios. For example, the preset unit time may be 2 minutes. The specific preset unit time length is not limited in the embodiments of the present application.
It should be noted that, in the embodiment of the present application, the second preset time duration may be a product of the number of times and the preset unit time duration, and of course, the second preset time duration may also be determined by adopting other calculation methods based on the number of times and the preset unit time duration, which is not limited in the embodiment of the present application.
It should be noted that, in the embodiment of the present application, the manner in which the terminal determines the second preset time length is only an exemplary manner, and certainly, the second preset time length may also be set according to an actual requirement, and the manner in which the second preset time length is determined is not limited in the embodiment of the present application.
It should be noted that, in this embodiment of the application, the second preset condition may be that the second cell where the terminal resides does not meet a communication condition corresponding to the current service requirement characteristic, where the communication condition may include a service provided by the second cell, signal quality, and the like. Of course, the specific second preset condition may also be set according to an actual requirement, for example, the second preset condition may also be that the terminal is in an idle mode, and the embodiment of the present application is not limited.
It should be noted that, in the embodiment of the present application, after the terminal selects to camp in the second cell, the terminal may establish connection with the network of the corresponding system and perform data transmission. The terminal 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 currently. The service requirement characteristics may include service types, data transmission rate requirements, and the like, wherein the service types may include voice service, video service, and data transmission service, and the data transmission rate requirements may include a high rate requirement, a medium rate requirement, and a low rate requirement. The terminal can determine whether the second preset condition is met based on the service requirement characteristics.
It can be understood that, in the embodiment of the present application, when an application program of a terminal runs, a service module initiating a service requirement in the application program may be obtained, and a current service requirement characteristic is 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.
It can be understood that, in the embodiment of the present application, the first cell is specifically an SA cell, and the second cell is specifically an LTE cell, if the LTE cell where the terminal resides can provide the service currently required by the terminal, and the signal quality meets the requirement of the service that needs to be performed on the data transmission rate, it can be determined that the LTE cell where the terminal resides meets the communication condition corresponding to the service requirement characteristic, and data transmission can be performed directly through a network to which the LTE cell is accessed. If the LTE cell where the terminal resides cannot provide the service required by the terminal currently or the signal quality does not meet the requirement of the service for the data transmission rate, the LTE cell where the terminal resides can be determined not to meet the communication condition corresponding to the service requirement characteristic, and the reselection priority of the SA cell can be recovered, so that the terminal can select the SA cell to reside.
In some embodiments, restoring the reselection priority corresponding to the first cell from the second reselection priority to the first reselection priority may include: the configuration of the priority parameter corresponding to the first cell is cancelled, that is, the previously configured priority parameter corresponding to the first cell is deleted. After the configuration of the priority parameter of the first cell is cancelled, when the terminal reselects the cell, the terminal can select the cell to reside according to the priority information issued by the network equipment, and because the priority information issued by the network equipment is usually that the reselection priority of the first cell is higher than the reselection priority of the second cell, the terminal can select the first cell to reside.
It should be noted that, in the embodiment of the present application, after the reselection priority corresponding to the first cell is restored from the second reselection priority to the first reselection priority, when the terminal is in an idle state and performs cell reselection, the first cell may be selected to camp on because the first reselection priority is higher than the third reselection priority of the second cell. After the terminal resides in the first cell, the terminal can perform RRC connection through the first cell and perform data transmission through the corresponding network. The normal operation of data service on the terminal can be ensured, and the actual requirements of users can be met.
In some embodiments, after the terminal resides in the second cell for the second preset duration, if the terminal meets the second preset condition, the recovering the reselection priority of the first cell, that is, the recovering the reselection priority corresponding to the first 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 first cell from the second reselection priority to the first reselection priority.
When the terminal reduces the reselection priority corresponding to the first cell, the terminal may configure the priority parameter corresponding to the first cell as the second reselection priority, and record a configuration time, which is a time when the priority parameter corresponding to the first 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 stated that the configured priority parameter of the first cell is invalid, the configuration of the priority parameter corresponding to the first cell can be cancelled, and the configured priority parameter of the first cell is deleted, so as to recover the reselection priority corresponding to the first cell. The time of the terminal in the second cell can be accurately controlled by setting the effective duration for reducing the reselection priority corresponding to the first cell, the cell can be selected more flexibly to reside, and different requirements of users are met while power consumption is reduced.
It should be noted that, in this embodiment of the present application, after the terminal camps in the second cell, in order to make the terminal camp in the second cell for a second preset time period, the terminal may perform the following steps: and prohibiting the reselection priority of the first cell from being recovered and closing the background search of the first cell within a second preset time length.
It can be understood that, in the embodiment of the present application, after the terminal resides in the second cell, in order to avoid immediately reselecting the cell after residing in the second cell, in a case of residing in the first cell, the terminal may prohibit, within a certain time period, that is, within a second preset time period, recovering of the reselection priority of the first cell, and close the background search of the first cell, so that the terminal cannot implement cell reselection from the second cell to the first cell, and maintain residing in the second cell within the second preset time period, thereby reducing power consumption of the terminal and avoiding frequent switching of the residing cell.
In the embodiment of the application, the reselection priority corresponding to the first cell can be reduced or recovered according to the actual service requirement condition of the terminal, so that the terminal can be ensured to select a proper cell for residence, the power consumption of the terminal is reduced, and the cruising ability of the terminal is improved.
Fig. 3 is a flowchart illustrating a cell camping method according to an embodiment of the present application. As shown in fig. 3, in an embodiment, the cell camping method may further include the following steps:
s301, if the network abnormality exists in the first cell where the terminal resides currently, the reselection priority of the first cell is reduced.
After the terminal resides in the first cell for a first preset time, if data transmission needs to be performed through a network corresponding to the first cell, whether network abnormality exists in the resident first cell can be detected. Optionally, the network anomaly may include, but is not limited to, an abnormal configuration of the first cell, a Random Access (RA) failure rate greater than a failure rate threshold, and the like, wherein the abnormal configuration of the first cell may include an abnormal physical cell identifier of the NR cell (e.g., an identifier collision with other cells, and the like), an abnormal power parameter of the first cell (e.g., a reference signal power, and the like), and the like. The random access process is a process in which the terminal and the RRC layer of the base station interact through a set of messages, and the management and control of the RRC on the whole protocol stack are realized through such a process. The first cell where the terminal resides has network abnormality, which may affect normal data transmission of the terminal and is not performed by using services. When the network abnormality of the first cell is detected, it may be determined that the terminal satisfies a first preset condition, so as to reduce the reselection priority corresponding to the first cell.
S302, reselecting the second cell to reside.
When the terminal is in an idle state, because the reduced reselection priority of the first cell is the second reselection priority and is lower than the third reselection priority of the second cell, the second cell can be selected to reside, and after the terminal is accessed to a network corresponding to the second cell, data transmission is performed through the network.
In some embodiments, after the terminal detects that a network anomaly exists in a currently camped first cell and reduces a reselection priority corresponding to the first cell, when the terminal is in an idle state and performs cell reselection, if a searched cell only includes the first cell but not the second cell, the terminal may measure neighboring cells of the currently camped first cell and select a cell with the best signal quality to camp according to the measured signal quality of each cell.
In some embodiments, other scenarios for reducing the reselection priority corresponding to the first cell and restoring the reselection priority corresponding to the first cell may also be set. For example, a first time period for decreasing the reselection priority corresponding to the first cell may be set, and when the terminal is in the first time period, the reselection priority corresponding to the first cell is the second reselection priority and may be lower than the third reselection priority corresponding to the second cell. For example, 1 to 6 am every day may be set as a time period for decreasing the reselection priority corresponding to the first cell, and during the time period, the terminal may choose to camp on the second cell, and when the time period ends, the reselection priority corresponding to the first cell may be restored. For example, a second time period for recovering the reselection priority corresponding to the first cell may also be set, and when the terminal is in the second time period, the reselection priority corresponding to the first cell is the first reselection priority and may be higher than a third reselection priority corresponding to the second cell. For example, 12 to 14 and 19 to 21 points of each day may be set as a time period for recovering the reselection priority corresponding to the first cell, during which the terminal may choose to camp on the first cell, and when the time period ends, the reselection priority corresponding to the first 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 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 first 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 first 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 first cell and recovering the reselection priority corresponding to the first cell are not limited to the scenarios described in the foregoing embodiments, and the scenarios of reducing the reselection priority corresponding to the first cell and recovering the reselection priority corresponding to the first cell are not limited in the embodiments of the present application.
