Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. 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.

In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, 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. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

With the continuous development of terminal technology, more and more functions are supported by the terminal. The terminal may for example support communication services. The communication service includes, but is not limited to, a massage data transmission service, a call making service, a video playing service, and the like. A terminal capable of providing a normal communication service must start camping on one cell. Specifically, after the user identification card is installed in the terminal, the terminal may select one of the cells to camp on, where the cell is a camped cell.

Fig. 1 is a schematic view illustrating an application scenario of a cell search method or a cell search apparatus applied to an embodiment of the present application. A current location of the terminal 100 is covered with a plurality of cells, which may be, for example, a 5G cell Q cell, a 5G cell W cell, a 4G cell E cell, and a 4G cell R cell, respectively. When the terminal is in the coverage of different cells, the resident cell of the terminal may also change accordingly. For example, when the terminal is in the coverage of the qcell, the terminal may camp on the qcell, i.e., the terminal may camp on the 5G cell.

It is easily understood that, when the terminal moves from the coverage of the Q cell to the coverage of the R cell, the terminal may switch the camping cell from the Q cell to the R cell. At this time, the terminal may start a timer to continuously search for the 5G cell. However, when the terminal is in the coverage of the cell without 5G, the terminal may continuously search for the cell without 5G, which may increase the power consumption of the terminal and reduce the service life of the terminal.

The present application will be described in detail with reference to specific examples.

In one embodiment, as shown in fig. 2, a cell search method is proposed, which may be implemented by means of a computer program and may be run on a terminal based on a terminal having a subscriber identity card. The computer program may be integrated into the application or may run as a separate tool-like application.

Specifically, the cell search method includes:

s101, searching a third cell when the resident cell is switched from the first cell to the second cell;

according to some embodiments, a terminal must start camping on to a cell to provide normal communication services. Specifically, after the user identification card is installed in the terminal, the terminal may select one of the cells to camp on, where the cell is a camped cell. The execution main body of the embodiment of the application is a terminal comprising a user identification card. Subscriber identity cards are also known as subscriber identity modules, smart cards, SIM cards, etc. Subscriber identification cards include, but are not limited to, embedded SIM cards and non-embedded SIM cards. An embedded SIM card (eSIM card) is a conventional SIM card that is directly embedded on a chip of a terminal, rather than being added to the terminal as a separate removable component. Therefore, the terminal can be lighter and thinner by using the embedded SIM card, the manufacturing cost of the terminal is saved, and a user does not need to manually install the SIM card. The subscriber identity card includes, but is not limited to, a Central Processing Unit (CPU), a Read Only Memory image (ROM), a Random Access Memory (RAM), a charged Erasable Programmable Read-Only Memory (EEPROM), and an input/output I/O circuit.

It is easy to understand that the fifth Generation mobile communication technology (5th Generation mobile networks or 5th Generation wireless systems, 5th-Generation, 5G for short) is the latest Generation cellular mobile communication technology, and is an extension behind the 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (gsm) systems. A 5G cell refers to an area covered by a network device supporting a 5G network. The network device is a base station. A base station, i.e., a public mobile communication base station, is a form of a radio station, and refers to a radio transceiver station that performs information transfer with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. It is easily understood that The 4Generation mobile communication technology (4G) integrates 3G (3G) and WLAN, and can rapidly transmit data, high-quality audio, video, and image. 4G can be downloaded at a speed of 100Mbps or more, 20 times faster than the current 4 mb home broadband ADSL, and can meet the requirements of almost all users for wireless service. A 4G cell refers to an area covered by a network device supporting a 4G network, which is not covered by a network device supporting a 5G network.

The camping cell in the embodiment of the present application includes, but is not limited to, a 6th generation mobile communication technology (6G) cell, a 5G cell, a 4G cell, a 3G cell, and the like.

Optionally, the first cell refers to one of the camping cells, and the first cell does not refer to a certain fixed cell specifically, but refers to a cell before the camping cell of the terminal is switched to the second cell. The network system grade corresponding to the first cell is a first network system grade, and the network system grade corresponding to the second cell is a second network system grade. The first network system grade is larger than the second network system grade. For example, when the first cell is a 5G cell, the second cell may be a 4G cell. And the network system grade of the 5G cell is greater than that of the 4G cell. The first network system class does not refer to a fixed network system class, and for example, when the first cell changes, the first network system class also changes correspondingly.

In some embodiments, the second cell refers to a cell with a network system level smaller than the first network system level, and the second cell does not refer to a fixed cell specifically. The second cell may be determined based on a location of the terminal.

Optionally, the third network system class of the third cell is greater than the second network system class of the second cell. The third network system grade may be the same as the first network system grade, or may be different from the first network system grade. For example, when the first cell is a 6G cell, the second cell may be a 4G cell, the third cell may be a 5G cell, and the third cell may also be a 6G cell.

Optionally, when the terminal is installed with the subscriber identity module card and the terminal is in a power-on state, the terminal may acquire the residential cell. When the terminal acquires the camping cell, the terminal may detect whether the camping cell is switched. The terminal may search for a third cell when the terminal determines that the camped cell is handed over from the first cell to the second cell. The third cell searched by the terminal may be the same as the first cell before the terminal-camped cell is switched to the second cell, or may be different from the first cell before the terminal-camped cell is switched to the second cell.

It is readily understood that the first cell may be, for example, a 5G cell, the second cell may be, for example, a 4G cell, and the third cell may be, for example, a 5G cell. When the terminal determines that the camping cell is switched from the 5G cell to the 5G cell, the terminal may search for the 5G cell.

Optionally, the first cell may be, for example, a 6G cell, the second cell may be, for example, a 4G cell, and the third cell may include, for example, both a 6G cell and a 5G cell. When the terminal determines that the camping cell is switched from the 6G cell to the 5G cell, the terminal may search for the 6G cell and the 5G cell simultaneously.

S102, if the search duration reaches a duration threshold and the third cell is not searched, stopping searching the third cell;

according to some embodiments, the search duration refers to a duration corresponding to a cell search in the terminal. The search time length corresponds to at least one search time. The search duration refers to a search duration started after the terminal determines that the resident cell is switched from the first cell to the second cell. The search duration is not specifically referred to as a fixed duration. The search duration may be set by the terminal based on the duration setting instruction, or may be set by the terminal when leaving the factory. The duration setting instruction may be, for example, a preset text duration setting instruction. Wherein, different search times may correspond to different search durations. For example, the search duration corresponding to the first search may be, for example, 1 second, and the search duration corresponding to the second search may be, for example, 2 seconds.

According to some embodiments, the duration threshold refers to a threshold corresponding to the search duration. The duration threshold is not particularly limited to a fixed threshold, and the duration threshold may be modified based on a duration modification instruction acquired by the terminal, for example. The duration modification instruction includes, but is not limited to, a voice duration modification instruction, a click duration modification instruction, a text duration modification instruction, and the like.

Alternatively, when the terminal determines that the camping cell is switched from the first cell to the second cell, the terminal may search for a third cell. When the terminal starts to search for the third cell, the terminal may obtain the search duration, and detect whether the search duration reaches the duration threshold and whether the third cell is searched within the search duration. If the terminal does not search the third cell when the search duration reaches the duration threshold, the terminal may stop searching the third cell.

It will be readily appreciated that the duration threshold may be, for example, 15 seconds. When the terminal starts searching for the third cell, the terminal may acquire the search duration. When the terminal detects that the search duration reaches the duration threshold of 15 seconds and the third cell is not searched, the terminal may stop searching for the third cell.

And S103, if the displacement distance of the terminal is greater than or equal to the distance threshold, searching the third cell again.

According to some embodiments, after the terminal stops searching for the third cell, the terminal may detect whether the terminal is displaced. When the terminal determines that the terminal is displaced, the terminal can acquire the displacement distance of the terminal. When the terminal obtains the displacement distance of the terminal, the terminal can detect the size relationship between the displacement distance of the terminal and the distance threshold. The distance threshold merely refers to a threshold corresponding to a displacement distance of the terminal, and the distance threshold does not refer to a fixed threshold. When the terminal receives a modification instruction for the distance threshold, the terminal may modify the threshold based on the distance modification instruction. The modification instructions include, but are not limited to, voice distance modification instructions, click distance modification instructions, timing distance modification instructions, and the like.

Optionally, when the terminal determines that the displacement distance of the terminal is greater than or equal to the distance threshold, the terminal may search for the third cell again. The distance threshold may be, for example, 1 km. The displacement distance when the terminal acquires the terminal may be, for example, 1.5 km. And when the terminal determines that the displacement distance 1.5km of the terminal is greater than the distance threshold value 1km, the terminal can search the third cell again.

According to some embodiments, when the terminal receives a modification instruction for the distance threshold, the terminal may modify the threshold based on the modification instruction. When the modification instruction received by the terminal is a voice modification instruction, a microphone may be disposed on the terminal, and the microphone may be configured to collect a voice signal input by a user. When the terminal controls the microphone to collect the voice signal, the terminal can analyze the voice signal by adopting a voice recognition algorithm to obtain a voice modification instruction input by a user.

Optionally, when the modification instruction received by the terminal is a click modification instruction, a modification control may be set on the terminal, and the modification control is used to modify the distance threshold. When the terminal is provided with the modification control and detects that the user clicks the modification control, the terminal can receive a click modification instruction. At this time, the interface display of the terminal may be as shown in fig. 3, for example.

Optionally, before the modification instruction received by the terminal is the timing modification instruction, the terminal may set a modification time every fixed time, may also set a fixed time every day as the modification time, and may also set the next modification time based on the last modification completion. When the preset modification time is reached, the terminal can receive the timing modification instruction.

In one or more embodiments of the present application, when a resident cell is switched from a first cell to a second cell, a search duration is started, a third cell is searched, a first network system level of the first cell is greater than a second network system level of the second cell, a third network system level of the third cell is greater than the second network system level, if the search duration reaches a duration threshold and the third cell is not searched, the search of the third cell is stopped, and if a displacement distance of a terminal is greater than or equal to a distance threshold, the third cell is searched again. Therefore, the third cell is searched only when the displacement distance of the terminal is greater than or equal to the distance threshold, that is, when the terminal is in the coverage range without the third cell and the terminal does not move, the terminal does not search the third cell, so that the power consumption for continuously searching the third cell can be reduced, the power consumption for cell search can be reduced, and the service life of the terminal can be prolonged.

Please refer to fig. 4, which is a flowchart illustrating a cell search method according to an embodiment of the present application. As shown in fig. 4, the method comprises the following steps S201-S208.

S201, when the resident cell is switched from a first cell to a second cell, searching a third cell;

the specific process is as described above, and is not described herein.

It is easy to understand that, when the camping cell is switched from the first cell to the second cell and there are multiple second cells, the terminal may obtain signal strength values of the multiple second cells respectively, and determine the second cell with the highest signal strength value as the second cell in which the terminal camps.

S202, if the searching time length reaches a time length threshold value and the third cell is not searched, stopping searching the third cell;

the specific process is as described above, and is not described herein.

According to some embodiments, the terminal may detect whether the search duration reaches the duration threshold, for example, by setting a timer. For example, the terminal may start the timer when the terminal starts searching for a third cell when it determines that the camping cell is switched from the first cell to the second cell. The first cell may be a first 5G cell, the second cell may be, for example, a 4G cell, and the third cell may be, for example, a second 5G cell. For example, the first 5G cell may be an a cell, for example. The 4G cell may be, for example, a B cell. The timer may be, for example, a Z timer. When the camping cell of the terminal is switched from the first 5G cell A cell to the 4G cell B cell, the terminal may start the Z timer to search for the third cell.

Optionally, before the terminal closes the timer, the terminal may search for the third cell within a preset number of times. When the third cell is not searched within the preset timing number, the terminal can stop searching the third cell, so that the condition that the cell search is inaccurate due to one-time search can be reduced, and the accuracy of the cell search can be improved. The timing times of each time can correspond to the same duration or different durations.

It is easy to understand that the timing duration corresponding to different timing times can be different, and the greater the timing times, the longer the corresponding timing duration. For example, the number of times may be proportional to the timing duration, for example, the timing duration of the first time may be less than the timing duration of the second time, and the timing duration of the second time may be less than the timing duration of the third time.

Optionally, the search duration may be controlled by the terminal through a timer set in the terminal, for example. The number of the timer may be at least one.

S203, acquiring a first position and a second position;

according to some embodiments, the first location is a location of the terminal when the terminal is camped on the first cell. The first position is not specific to a fixed position. When the first cell in which the terminal resides changes, the first location changes accordingly. The second position is the current position of the terminal. The second position is not specific to a fixed position. When the current position of the terminal changes, the second position also changes correspondingly. When the moving direction of the terminal position is different, the second position is changed correspondingly. The location may be, for example, a latitude and longitude location, and the location may be, for example, a textual description location. The first position acquired by the terminal may be, for example, a T1 position, and the second position may be, for example, a T2 position.

According to some embodiments, when the terminal acquires the first location and the second location, the terminal may acquire the location information reported by the base station and a reporting time point corresponding to the location information. The terminal may determine the first location and the second location based on the location information and the reporting time point.

According to some embodiments, when the location of the terminal changes, the base station may report the location information and a reporting time point corresponding to the location information to the terminal. When the terminal detects that the base station sends the position information, the terminal can acquire the position information and a reporting time point corresponding to the position information. The reporting time point is used for indicating the acquisition time of the position information.

It is readily understood that the first cell may be, for example, a 5G cell a cell and the second cell may be, for example, a 4G cell B cell. And when the resident cell of the terminal is switched from the first cell A cell to the second cell B cell, starting a timer, and searching a third cell within the searching time length determined by the timer. When the search duration reaches the duration threshold and the third cell is not searched, that is, when the timer is timed out and the third cell is not searched, the terminal may stop searching the third cell. When the terminal is displaced and is within the coverage of the cell B of the 4G cell, the base station may send the location information of the cell B and the reporting time point corresponding to the location information to the terminal. The terminal can obtain the position information of the B cell and the reporting time point corresponding to the position information.

According to some embodiments, when the terminal acquires the location information and the reporting time point reported by the base station, the terminal may determine the first location and the second location. The first position is the position of the terminal closest to the current time and where the terminal was camped on the last first cell. For example, the first location may be the location of a first cell a cell.

According to some embodiments, when the terminal determines the first location and the second location based on the location information, the terminal may directly determine the first location and the second location based on the location information reported by the base station, and the terminal may further determine the first location and the second location based on the location information reported by the base station and the signal strength obtained by the terminal.

S204, determining the distance between the first position and the second position as the displacement distance of the terminal;

according to some embodiments, when the terminal acquires the first position and the second position, the terminal may determine a distance between the first position and the second position as a displacement distance of the terminal. That is, when the terminal acquires the first position and the second position, the terminal may acquire the distance between the first position and the second position.

S205, if the displacement distance of the terminal is larger than or equal to the distance threshold, searching a third cell again;

the specific process is as described above, and is not described herein.

According to some embodiments, when the terminal acquires the first position and the second position, the terminal may determine a distance between the first position and the second position as a displacement distance of the terminal. When the terminal determines that the displacement distance is greater than or equal to the distance threshold, that is, the terminal determines that the distance between the first position and the second position is greater than or equal to the distance threshold, the terminal may re-search for the third cell. When the terminal re-searches for the third cell, the terminal may re-search for the third cell for the search duration.

Alternatively, the distance threshold may be, for example, 1 km. The first and second locations may be, for example, latitude and longitude type locations. The first position acquired by the terminal may be, for example, a T1 position, the T1 position may be, for example, a T1 longitude and latitude, the second position may be, for example, a T2 position, and the T2 position may be, for example, a T2 longitude and latitude. The terminal may obtain the distance between the first location and the second location, which may be, for example, 2km, and may calculate the distance of T1 latitude and T2 latitude and longitude. When the terminal determines that the distance 2km between the first location and the second location is greater than the distance threshold 1km, the terminal may restart the timer and re-search for the third cell.

S206, when the third cell is searched in the search duration, the resident cell is switched from the second cell to the third cell;

according to some embodiments, when the terminal re-searches for the third cell, the terminal may detect whether the third cell is searched for within the search duration. When the terminal searches for the third cell within the search duration, the terminal may switch the camping cell from the second cell to the third cell. Wherein, the terminal may set a search duration for re-searching the third cell based on the duration setting instruction of the user.

According to some embodiments, the search duration may include, for example, a first search duration and a second search duration, where the first search duration may be a duration for searching for a third cell when the terminal determines that the camping cell is handed over from the first cell to the second cell, and the second search duration may be a duration for re-searching for the third cell when the terminal determines that the location distance is greater than the distance threshold. Wherein the first search time period may be equal to the second search time period, and both are controlled by the timer. The first cell may be, for example, a first 5G cell a cell. The second cell may be, for example, a 4G cell B cell. The terminal may be timed using a timer, for example. The timer may be, for example, a Z timer. And when the resident cell of the terminal is switched from the first cell A cell to the 4G cell B cell, starting a Z timer and searching a third cell. The search duration determined by the Z-timer may be, for example, a first search duration. And when the first search time reaches the time threshold and the third cell is not searched, closing the timer and stopping searching the third cell, namely when the search time does not search the third cell, stopping searching the third cell. When the terminal detects that the terminal is displaced, the terminal can acquire the distance between the first position and the second position. I.e. the terminal can obtain the distance between the current terminal position and the terminal position when the terminal is camped on the a cell. The distance between the first location and the second location acquired by the terminal may be, for example, 2 km. When the terminal determines that the distance 2km between the first location and the second location is greater than the distance threshold 1km, the terminal may restart the timer and re-search for the third cell, that is, the terminal may re-search for the third cell within the second search duration. The second search time period determined by the timer may be, for example, 15 seconds. When the terminal searches for the third cell D cell in the 4 th second, the terminal may switch the camping cell from the 4G cell B cell to the third cell D cell. Where the D cell may be, for example, a 5G cell.

It is easily understood that, when the terminal searches for the third cell within the search duration, the terminal may switch the camping cell from the second cell to the third cell. When the terminal switches the resident cell from the second cell to the third cell, the terminal may send a prompt message for prompting that the resident cell is the third cell. The prompt message may be, for example, that the cell in which the terminal currently resides is the third cell scell. At this time, an exemplary diagram of the terminal interface may be as shown in fig. 5.

According to some embodiments, the terminal may acquire search information corresponding to the re-search of the third cell and set a search flag corresponding to the search information. The search flag bit comprises a first search flag bit and a second search flag bit; the first search flag bit is used for indicating the terminal to search a third cell; the second search flag is used to indicate that the terminal does not search for the third cell. The search information includes, but is not limited to, searched third cell and not searched third cell. When the terminal searches for the third cell, the terminal may set the search flag to the first search flag. When the terminal does not search for the third cell, the terminal may set the search flag to the second search flag.

Optionally, when the camping cell is switched from the first cell to the second cell, the terminal may search for a third cell. When the search duration reaches the duration threshold and the third cell is not searched, and the search of the third cell is stopped, the terminal may set the search flag to be the second search flag.

According to some embodiments, when the terminal re-searches for the third cell, the terminal may detect whether the third cell is searched for within the search duration. When the terminal searches for the third cell within the search duration, the terminal may switch the camping cell from the second cell to the third cell. The terminal may set the search flag to the first search flag at this time.

It is easy to understand that, when the search information corresponding to the third cell is the third cell, the search flag set by the terminal may be the first search flag. When the search information corresponding to the third cell is that the search of the third cell is stopped, the search flag set by the terminal may be a second search flag.

According to some embodiments, the terminal may obtain the search flag when the terminal is powered on. When the terminal acquires the search flag, the terminal may determine, based on the search flag, a cell where the terminal resides for the first time after being turned on. When the terminal determines the first resident cell after the terminal is powered on based on the search flag bit, the terminal may obtain search information corresponding to the search flag bit. When the search flag bit acquired by the terminal is the first search flag bit, the terminal can search the third cell because the first search flag bit indicates the terminal to search the third cell. When the terminal searches for a third cell, the terminal may camp on the third cell. When the search marker bit acquired by the terminal is the second search marker bit, the second search marker bit is used for indicating that the terminal does not search the third cell, so that the terminal can be directly started without searching the cell, the starting time of the terminal can be reduced, and the power consumption of the terminal for searching the cell is reduced.

And S207, when the displacement distance of the terminal is smaller than the distance threshold value, the terminal continuously resides in the second cell.

According to some embodiments, when the terminal acquires the first position and the second position, the terminal may determine a distance between the first position and the second position as a displacement distance of the terminal. And when the displacement distance determined by the terminal is smaller than the distance threshold value, namely the distance between the first position and the second position is smaller than the distance threshold value, the terminal continuously resides in the second cell.

Optionally, the search duration may include, for example, a first search duration and a second search duration, where the first search duration may be a duration for searching for a third cell when the terminal determines that the camping cell is switched from the first cell to the second cell, and the second search duration may be a duration for searching for the third cell again when the terminal determines that the location distance is greater than the distance threshold. Wherein the first search time period may be equal to the second search time period, and both are controlled by the timer. The first cell may be, for example, a first 5G cell a cell. The second cell may be, for example, a 4G cell B cell. The timing duration may be controlled, for example, by a timer, which may be, for example, a Z timer. When the resident cell of the terminal is switched from the first cell a to the second cell B, the Z timer is started to search for the third cell, that is, the terminal may search for the third cell within the first search duration. And when the timer is timed out and the third cell is not searched, closing the timer, namely when the searching time length reaches the time length threshold value and the third cell is not searched, stopping searching the third cell by the terminal. The distance threshold may be, for example, 1 km. The first position acquired by the terminal may be, for example, a T1 position, the T1 position may be, for example, a T1 longitude and latitude, the second position may be, for example, a T2 position, and the T2 position may be, for example, a T2 longitude and latitude. The first and second locations may be, for example, latitude and longitude type locations. The terminal may obtain the distance between the first location and the second location, which may be, for example, 0.5km, and may calculate the distance of T1 latitude and T2 latitude and longitude. The terminal may continue camping on the second cell B cell when the terminal determines that the distance between the first location and the second location is 0.5km less than the distance threshold 1 km.

In one or more embodiments of the present application, when a resident cell is switched from a first cell to a second cell, a third cell is searched, if a search duration reaches a duration threshold and the third cell is not searched, the third cell is stopped being searched, the terminal may determine an acquired distance between a first location and a second location as a displacement distance of the terminal, when the displacement distance of the terminal is greater than or equal to a distance threshold, the third cell is searched again, only when the displacement distance of the terminal is greater than or equal to the distance threshold, the third cell is searched, that is, only when the displacement distance of the terminal is greater than or equal to the distance threshold, a cell with a higher network system level is searched, when the terminal is in a coverage area without the third cell, the terminal may not search the third cell, power consumption for continuously searching the third cell may be reduced, and power consumption for searching the cell may be reduced, the service life of the terminal can be prolonged. And secondly, when the third cell is searched in the searching duration, the resident cell is switched from the second cell to the third cell, so that the convenience of the terminal in use can be improved when the cell searching power consumption is reduced. In addition, when the displacement distance of the terminal is smaller than the distance threshold, the terminal continuously resides in the second cell, so that the situation that the terminal does not reside in the cell can be reduced, and the convenience of the terminal in use can be improved.

Please refer to fig. 6, which is a flowchart illustrating a cell search method according to an embodiment of the present application. As shown in fig. 6, the method comprises the following steps S301-S305.

S301, searching a third cell when the resident cell is switched from the first cell to the second cell;

the specific process is as described above, and is not described herein.

S302, if the search time reaches a time threshold and the third cell is not searched, stopping searching the third cell;

the specific process is as described above, and is not described herein.

S303, sending out prompt information;

according to some embodiments, when the terminal determines that the search duration reaches the duration threshold and does not search for the third cell, the terminal may stop searching for the third cell. The terminal may send out a prompt message. The prompting information is used for prompting that the third cell is not searched within the searching duration. The prompting information may also include, for example, whether to set a starting point in time for re-searching the third cell.

It is easily understood that the search duration may include, for example, a first search duration and a second search duration, where the first search duration may be a duration for searching for a third cell when the terminal determines that the camping cell is handed over from the first cell to the second cell, and the second search duration may be a duration for re-searching for the third cell when the terminal determines that the location distance is greater than the distance threshold. Wherein the first search time period may be equal to the second search time period, and both are controlled by the timer. The first cell may be, for example, an a-cell. The second cell may be, for example, a 4G cell B cell. The timer may be, for example, a Z timer. When the resident cell of the terminal is switched from the first cell a to the second cell B, the Z timer is started to search for the third cell, that is, the terminal may search for the third cell within the first search duration. When the timer is timed out and the third cell is not searched, the timer is turned off, that is, when the search duration reaches the duration threshold and the third cell is not searched, the terminal may stop searching for the third cell. The prompt information sent by the terminal at this time may be, for example, information that the third cell is not searched within the search duration and that the user is prompted to set a starting time point for re-searching the third cell.

S304, receiving a cell search instruction aiming at the prompt message;

according to some embodiments, when the terminal issues the alert information, the terminal may detect whether a cell search instruction for the alert information is received. The cell search instruction is for instructing to re-search for a third cell. When the terminal acquires the cell search instruction, the terminal may parse the cell search instruction to acquire a start time point for re-searching the third cell. If the search duration is controlled by the timer, the terminal may obtain a time point for restarting the timer. The cell search command includes, but is not limited to, a voice cell search command, a click cell search command, a text cell search command, and the like.

It is easy to understand that the prompt information issued by the terminal at this time may be, for example, information that the third cell is not searched and that the user is prompted to set a time point of the restart timer. The terminal receiving the cell search instruction for the prompt information may be, for example, restarting a timer after 1 hour.

S305, if the starting time point is reached, searching for the third cell again.

According to some embodiments, when the terminal receives a cell search instruction for the prompt message, the terminal may acquire a start time point for re-searching the third cell corresponding to the cell search instruction. When the terminal acquires the starting time point for searching the third cell again, the terminal may search the third cell again when the starting time point is reached.

It is easy to understand that the prompt information sent by the terminal at this time may be, for example, information that the third cell is not searched within the search duration and that the user is prompted to set the starting time point for re-searching the third cell. For example, the cell search instruction for the prompt information received by the terminal searching for the third cell may be, for example, 1 hour later to restart the timer. When the terminal can start a 1 hour countdown when receiving the cell search instruction. When the terminal determines that the 1-hour countdown is finished, that is, the terminal determines that a time point for restarting the timer is reached, the terminal may restart the timer and re-search for a third cell.

In one or more embodiments of the present application, when a resident cell is switched from a first cell to a second cell, a third cell is searched, if a search duration reaches a duration threshold and the third cell is not searched, the third cell is stopped being searched, a terminal may send a prompt message, and when a cell search instruction for the prompt message is received and a start time point for re-searching the third cell is reached, the third cell is re-searched. Therefore, the third cell is searched only when the starting time point for searching the third cell again set by the user is reached, so that the power consumption of the terminal for continuously searching the third cell in the coverage range without the third cell can be reduced, the power consumption for searching the cell can be reduced, and the service life of the terminal can be prolonged.
