Description

Method, device and system for manually searching network

Technical Field

The present application relates to the field of communications, and in particular, to a method, an apparatus, and a system for manually searching a network.

Background

At present, most terminals can support two network searching modes, namely automatic network searching and manual network searching. In the automatic network searching mode, the terminal will try to register all available operator networks one by one until registering the appropriate operator network. When the user is in a roaming state, the user may preferentially start a manual network search for reasons of cost, service quality and the like, and select a mobile network with lower access cost and/or better signal quality according to the network search result.

However, the priority of the manual network searching is very low, and the manual network searching is easily interrupted by high-priority services such as short messages and telephones and is directly terminated, so that the manual network searching fails, and the user experience is poor.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The technical solution of the embodiment of the present application may be applied to various communication systems, such as a global system for mobile communications (GSM), a General Packet Radio Service (GPRS) communication system, a Code Division Multiple Access (CDMA) communication system, a Wideband Code Division Multiple Access (WCDMA) communication system, a time-division multiple access (time-division code division multiple access, TD-SCDMA) communication system, a Long Term Evolution (LTE) communication system, a fifth generation (5th generation, 5G) communication system, such as a new radio, NR (radio, NR) system, and a future communication system, such as a 6G system.

This application is intended to present various aspects, embodiments or features around a system that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, a combination of these schemes may also be used.

In addition, in the embodiments of the present application, words such as "exemplarily", "for example", etc. are used for indicating as examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the term using examples is intended to present concepts in a concrete fashion.

In the embodiment of the present invention, "information", "signal", "message", "channel", "signaling" may be used in combination, and it should be noted that the meaning to be expressed is consistent when the difference is not emphasized. "of", "corresponding", and "corresponding" may sometimes be used in combination, it being noted that the intended meaning is consistent when no distinction is made.

In the examples of the present application, the subscripts are sometimes as W₁It may be mistaken for a non-subscripted form such as W1, whose intended meaning is consistent when the distinction is de-emphasized.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

In the embodiment of the present application, a part of scenarios will be described by taking a scenario in the communication system shown in fig. 1 as an example. It should be noted that the solution in the embodiment of the present application may also be applied to other mobile communication systems, and the corresponding names may also be replaced with names of corresponding functions in other mobile communication systems.

Fig. 1 is a schematic architecture diagram of a communication system applicable to the embodiment of the present application. As shown in fig. 1, the communication system includes a terminal, and one or more network devices, such as a network device 1 and a network device 2. The network device may also be referred to as an access network device, and is used to provide a cell for the terminal to access. The terminal may obtain configuration information of a cell provided by the network device in an automatic network search or manual network search manner, such as a frequency band (band), a frequency point (frequency point), a physical cell identity (PID), a network identity of a Public Land Mobile Network (PLMN) to which the cell belongs, and an operator to which the cell belongs, so that the terminal may select an access mobile network.

Specifically, the terminal may first perform a network search based on the prior information. Illustratively, the terminal may obtain prior information from a Network Variable (NV) configuration item or a Subscriber Identity Module (SIM) card file, such as a Registered Public Land Mobile Network (RPLMN), a public land mobile network (equivalent HPLMN) equivalent to a Home Public Land Mobile Network (HPLMN), and so on. After the terminal reads the RPLMN or the EPLMN successfully, the terminal tries all access technologies supported by the UE in the PLMN to initiate designated PLMN searching, and the network searching sequence can be determined according to the priority of the access technologies supported by the terminal. For example, automatic network searching or manual network searching may be performed in sequence according to the sequence of a 5G network, a 4G network, a 3G network, and a 2G network.

It should be understood that when there is no prior information, for example, in a startup scenario, the terminal may also directly enter an automatic network searching process or a manual network searching process, so as to perform full-system and full-band network searching. Of course, the automatic network searching sequence or the manual network searching sequence can also be controlled by the SIM card file or NV item.

Illustratively, if the network is set to automatically search for a network, the terminal selects PLMNs to search in the following order from a) to d):

a) HPLMN/EHPLMN: reading EFIMSI (IMSI), EFAD (administrative data) card files to obtain information of HPLMN/EHPLMN and access technology thereof.

b) UPLMN (prioritized): the terminal reads the efplmnwact (user controlled PLMN selector with access technology) card file to obtain information of the UPLMN and its access technology.

c) OPLMN (prioritized): the terminal reads the efoplmnwact (operator controlled PLMN selector with Access technology) card file to obtain the information of the OPLMN and its Access technology.

d) Other plmns (other plmns): the terminal may search for other PLMNs when searching for the PLMN, and since the PLMN does not match the searched PLMN, the terminal does not attempt to camp on but records the PLMN and its access technology. For other PLMNs, the terminal is generally divided into other PLMNs with good signal quality (random arrangement) and other PLMNs with poor signal quality (arrangement from high to low according to the signal quality).

Then, the terminal can automatically select the PLMN with the highest priority in the automatic network searching result to initiate a registration request.

Illustratively, if the network is set to manually search for a network, the terminal will list all the searched PLMNs, even if this PLMN is not in the FPLMN list, or if the access technologies supported by this PLMN are not the access technologies supported by the terminal (i.e., access technology inconsistency). The result list of the manual network searching is generally arranged according to the following sequence:

e) HPLMN/EHPLMN (possibly only one PLMN of highest priority, or both);

f) PLMNs in the USIM file "user controlled PLMN selector with access technology" (these PLMNs are prioritized in the USIM);

g) PLMNs in the USIM file "operator controlled PLMN selector with access technology" (these PLMNs are prioritized in the USIM);

h) the PLMNs with better signal quality are arranged randomly;

i) and other PLMNs are arranged in the order of high signal quality to low signal quality.

The existing manual web searching may generally include the following stages: frequency sweep, Cell Search (CS), solve system messages, etc. The frequency sweep is used for scanning frequency band information and frequency point information of a cell with a stronger signal on each frequency band of each system supported by the terminal; the cell search is used for searching Physical Cell Identification (PCID) of a cell scanned in a frequency sweeping phase; and the system message is used for trying to reside the searched cell and trying to analyze the PLMN identification and the operator information carried by the system message. The system message may include a Master Information Block (MIB) and a System Information Block (SIB).

Then, the user can manually select any PLMN in the result list of the manual network searching to initiate a registration request.

It should be noted that, in each stage of the above-mentioned manual network searching, when the manual network searching is interrupted by other services, such as a short message, a telephone call, etc., the Radio Resource Control (RRC) layer will immediately send a PLMN search reject (reject) message to the non-access stratum (NAS), and automatically switch the network searching mode from the manual network searching mode back to the automatic network searching mode. That is to say, the manual network searching cannot be recovered after being interrupted by other services, and no prompt information can be given, so that the user can only start a round of manual network searching again, and the user experience is poor.

The network device is a device located on the network side of the communication system and having a wireless transceiving function or a chip system installed on the device. The network devices include, but are not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), wireless relay Node, wireless backhaul Node, transmission point (transmission and reception point, TRP or transmission point, TP), etc., Access Point (AP) in wireless fidelity (WiFi) system, such as home gateway, router, server, switch, etc., and may be 5G, such as a new air interface (NR) system, or a network bridge in a Network Bridge (NB), a Transmission Point (TP), or a group of antennas including one or more antenna panels (antenna panels) in a base station system, alternatively, the network node may also be a network node forming a gNB or a transmission point, such as a baseband unit (BBU), or a Distributed Unit (DU), a roadside unit (RSU) having a base station function, or the like.

As shown in fig. 2, the terminal 200 includes a processor 210, an internal memory 221, an external memory interface 222, an antenna a, a mobile communication module 231, an antenna B, a wireless communication module 232, an audio module 240, a speaker 240A, a receiver 240B, a microphone 240C, an earphone interface 240D, a display screen 251, a Subscriber Identification Module (SIM) card interface 252, a camera 253, a button 254, a sensor module 260, a Universal Serial Bus (USB) interface 270, a charge management module 280, a power management module 281, and a battery 282. In other embodiments, the terminal may also include a motor, an indicator, and the like.

Processor 210 may include one or more processing units, among others. For example, the processor 210 may include an Application Processor (AP), a modem, a Graphics Processing Unit (GPU), an Image Signal Processor (ISP), a controller, a video codec, a Digital Signal Processor (DSP), a baseband processor, and/or a neural-Network Processing Unit (NPU), etc. It should be noted that the different processing units may be separate devices, or may be integrated into one or more separate processors, or may be integrated into the same device with other modules in the terminal. Taking the modem as an example, the modem may be a processing unit independent from the processor 210, may be integrated with other processing units (e.g., AP, ISP, GPU, etc.) in the same device, and may integrate some or all of the functions with the mobile communication module 231 in the same device.

The internal memory 221 may be used to store data and/or at least one computer program comprising instructions. Specifically, the internal memory 221 may include a program storage area and a data storage area. Wherein the storage program area may store at least one computer program. The computer programs may include application programs (such as galleries, contacts, etc.), operating systems (such as the Android operating system, or the IOS operating system, etc.), or other programs. The storage data area may store at least one of data created during use of the terminal, data received from other devices (e.g., other terminals, network devices, servers, etc.), data pre-stored before shipment, and the like. For example, the data stored in the internal memory 221 may be at least one of image, file, or identification information.

The processor 210 may make the terminal implement one or more functions by calling one or more computer programs and/or data stored in the internal memory 221, so as to meet the needs of the user. For example, the processor 210 may cause the electronic device to execute the method for controlling network searching provided in the embodiment of the present application by calling the instructions and data stored in the internal memory 221.

The external memory interface 222 may be used to connect an external memory card (e.g., a Micro SD card) to extend the storage capability of the terminal. The external memory card communicates with the processor 210 through the external memory interface 222 to implement a data storage function. For example, files such as images, music, video, etc. are saved in an external memory card.

In some embodiments, a buffer may be further disposed in the processor 210 for storing instructions and/or data that the processor 210 needs to use circularly, and if the processor 210 needs to use the instructions or data again, the instructions or data may be called directly from the buffer. Thereby helping to avoid repeated accesses and reducing the latency of the processor 210, thereby helping to improve the efficiency of the system. For example, the cache area may be implemented by a cache memory.

Antennas a and B are used to transmit and receive electromagnetic wave signals. Each antenna in a terminal may be used to cover a single or multiple communication bands. Different antennas can also be multiplexed to improve the utilization of the antennas. For example: antenna a may be multiplexed as a diversity antenna for a wireless local area network. In other embodiments, the antenna may be used in conjunction with a tuning switch.

The mobile communication module 231 may be configured to implement communication between the terminal and the network device according to a mobile communication technology (e.g., 2G, 3G, 4G, or 5G, etc.) supported by the terminal. For example, the mobile communication technology supported by the terminal may include at least one of GSM, GPRS, CDMA, WCDMA, TD-SCDMA, LTE, or NR, etc. For example, the terminal supports GSM, and after accessing the network through the cell provided by the BTS in the GSM communication system, the terminal can implement communication between the terminal and the BTS through the mobile communication module 231 under the condition that the network signal strength of the accessed cell is not lower than the decision threshold, that is, under the condition that the terminal is in the network-resident state. For example, the mobile communication module 231 may amplify the signal modulated by the modem and transmit the amplified signal to the network device via the antenna a; the mobile communication module 231 may also receive a signal transmitted by the network device through the antenna a, amplify the signal, and transmit the amplified signal to the modem, and the modem demodulates the received signal into a low-frequency baseband signal, and then performs other corresponding processing. In some embodiments, the mobile communication module 231 may include a filter, a switch, a power amplifier, a Low Noise Amplifier (LNA), and the like.

The wireless communication module 232 may provide solutions for wireless communication applied to the terminal, including wireless access networks (WLANs) (e.g., wireless-fidelity (Wi-Fi) networks), Bluetooth (BT), Global Navigation Satellite Systems (GNSS), Frequency Modulation (FM), Near Field Communication (NFC), Infrared (IR), and the like. The GNSS may include at least one of a Global Positioning System (GPS), a global navigation satellite system (GLONASS), a beidou satellite navigation system (BDS), a quasi-zenith satellite system (QZSS), and/or a Satellite Based Augmentation System (SBAS), and the like. Illustratively, the wireless communication module 232 may be one or more devices that integrate at least one communication processing module. The wireless communication module 232 may communicate with the corresponding device through the antenna B according to a wireless communication technology (e.g., Wi-Fi, bluetooth, FM, or NFC) supported by itself.

The terminal may receive a key input, and generate a key signal input related to user setting and function control of the terminal. For example, the terminal may count or gather some information about the use of the terminal by the user in response to selecting a virtual option indicating consent to participate in the "user experience improvement plan" to achieve a more personalized service for the user, thereby improving the user experience.

The sensor module 260 may include one or more sensors. For example, the sensor module 260 includes an acceleration sensor 260A, a touch sensor 260B, a fingerprint sensor 260C, and the like. In some embodiments, the sensor module 260 may also include pressure sensors, gyroscope sensors, environmental sensors, distance sensors, proximity light sensors, bone conduction sensors, and the like.

An acceleration sensor (ACC sensor)260A may collect the magnitude of acceleration of the terminal in each direction (generally, three axes). When the terminal is static, the size and the direction of gravity can be detected. In addition, the acceleration sensor 260A can also be used for recognizing the posture of the terminal, and is applied to horizontal and vertical screen switching, pedometer and other applications. In some embodiments, the acceleration sensor 260A may be implemented by a Micro Controller Unit (MCU) to be connected to the processor 210, thereby helping to save power consumption of the terminal. For example, the acceleration sensor 260A may be connected to the AP or the modem via the MCU. In some embodiments, the MCU may be a general-purpose smart sensing hub (Sensor hub).

The touch sensor 260B may also be referred to as a "touch panel". The touch sensor 260B may be disposed on the display screen 251, and the touch sensor 260B and the display screen 251 form a touch screen, which is also called a "touch screen". The touch sensor 260B is used to detect a touch operation applied thereto or therearound. Touch sensor 260B can communicate the detected touch operation to the AP to determine the touch event type. Then, the terminal provides visual output related to the touch operation through the display screen 251 according to the determined type of the touch event. In other embodiments, the touch sensor 260B can be disposed on the surface of the terminal at a different position than the display screen 251.

The fingerprint sensor 260C is used to capture a fingerprint. The terminal can utilize the acquired fingerprint characteristics to realize fingerprint unlocking, access an application lock, fingerprint photographing, fingerprint incoming call answering and the like.

Such as searching for a web, taking a picture, etc. In the embodiments of the present application, the connection mode of the interface in the terminal is not limited.

The SIM card interface 252 is used to connect a SIM card. The SIM card can be brought into and out of contact with the terminal by being inserted into the SIM card interface 252 or being pulled out of the SIM card interface 252. The terminal can support 1 or N SIM card interfaces, and N is a positive integer greater than 1. The SIM card interface 252 may support a Nano SIM card, a Micro SIM card, a SIM card, etc. Multiple cards can be inserted into the same SIM card interface 252 at the same time. The types of the plurality of cards may be the same or different. The SIM card interface 252 may also be compatible with different types of SIM cards. In some embodiments, the SIM card interface 252 may also be compatible with external memory cards. The terminal realizes functions of conversation, data communication and the like through the SIM card. In some embodiments, the terminal may also employ eSIM, namely: an embedded SIM card. The eSIM card can be embedded in the terminal and cannot be separated from the terminal.

The USB interface 270 is an interface conforming to the USB standard specification, and may specifically be a Mini USB interface, a Micro USB interface, a USB Type C interface, or the like. The USB interface 270 may be used to connect a charger to charge the terminal, or may be used to transmit data between the terminal and a peripheral device. And the earphone can also be used for connecting an earphone and playing audio through the earphone. The interface may also be used to connect other electronic devices, such as AR devices and the like.

It should be understood that the interface connection relationship between the modules in the embodiment of the present invention is only an exemplary illustration, and does not form a limitation on the structure of the terminal. In other embodiments of the present application, the terminal may also adopt different interface connection manners or a combination of multiple interface connection manners in the foregoing embodiments.

The charge management module 280 is configured to receive a charging input from a charger. The charger may be a wireless charger or a wired charger. The power management module 281 is used to connect the battery 282, the charging management module 280 and the processor 210. Power management module 281 receives inputs from battery 282 and/or charge management module 280 to power modules such as processor 210. In some embodiments, the power management module 281 may also be used to monitor parameters such as battery capacity, battery cycle number, battery state of health (leakage, impedance), etc.

It should be understood that the structure of the terminal shown in fig. 2 is only one example. A terminal of an embodiment of the application may have more or fewer components than shown, may combine two or more components, or may have a different configuration of components. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

The method for manually searching for a network provided by the embodiment of the present application will be specifically described below with reference to fig. 3 to fig. 15.

Fig. 3 is a flowchart illustrating a method for manually searching a network according to an embodiment of the present application. The manual network searching method may be applied to the process that the terminal shown in fig. 1 searches the configuration information of the cell provided by the network device 1 and/or the network device 2 in a manual network searching manner.

As shown in fig. 3, the method for searching for a network manually includes the following steps:

s301, responding to the operation of starting the manual network searching, and receiving the system message of the first cell.

The system message of the first cell carries configuration information of the first cell.

The system message of the first cell may generally include one or more of a Master Information Block (MIB) and a System Information Block (SIB), for example.

Specifically, the manual web search may be started through a Graphical User Interface (GUI) displayed on a touch screen of the terminal. For example, a manual web search may be initiated through a "setup" interface provided by the terminal on its touch screen.

Fig. 4-10 are schematic diagrams of terminal GUIs according to embodiments of the present application, first to seventh. How to initiate the manual web search will be described in detail below with reference to fig. 4-10. Illustratively, a manual web search may be initiated by performing the following steps:

step 1, click a "setting" icon (icon)401 on the terminal home page shown in fig. 4, and open a "setting" page shown in fig. 5.

As shown in fig. 4, in addition to the "set" icon, the main page may further include: date, time, weather forecast, mail, camera, gallery, phone, contact, player, WeChat, etc. The specific content on the main page may refer to the existing implementation manner, and is not described herein again.

As shown in FIG. 5, the "settings" page may include: "search settings" 402A, "flight mode," "WLAN" page entry, "Bluetooth" page entry, and other page entries, such as "more" 402B.

Step 2, as shown in fig. 5 and fig. 6, when a keyword "mobile network" is input at the "search setting item" 402A of the "setting" page, all search results meeting the conditions, such as the "mobile network" page entry 403 and the "mobile network sharing" page entry, are automatically displayed on the "setting" page.

Step 3, as shown in fig. 6, clicking the "mobile network" page entry 403, the "setup" page will jump to the "wireless and network" page as shown in fig. 7. As shown in fig. 7, the wireless and network pages may include a "mobile network" page entry 403 and a "mobile network shared" page entry.

The step 2 and the step 3 are the first method for opening the pages of the wireless and network provided by the embodiment of the present application. Alternatively, another method may be used to open the "wireless and network" pages. Specifically, clicking on the "more" settings page entry, as shown in FIG. 5, may jump to the "wireless and network" pages, as shown in FIG. 7.

Step 4, as shown in fig. 7, clicking the "mobile network" setup page entry 403, the "wireless and network" page will automatically jump to the "mobile network" page as shown in fig. 8.

As shown in fig. 8, the "mobile network" page typically includes a "mobile data" enable switch, a "network operator" page entry 404, and the like.

Step 5, as shown in fig. 8, clicking the "network operator" page entry 404, the "mobile network" page can automatically jump to the "network searching" page shown in fig. 9 and 10. As shown in fig. 9 and 10, the "search for web" page includes an "auto select" switch 405.

As shown in fig. 9, the "auto select" switch 405 is in an enabled state by default, which indicates that the terminal can search for a network by itself and select a wireless network to be accessed, i.e., automatically search for a network. For the automatic network searching, the existing implementation may be referred to, and details are not described here.

Alternatively, as shown in fig. 10, if the "auto select" switch 405 is disabled, it indicates that a manual network search is initiated. In other words, the "auto select" switch 405 is turned off, and the manual network search is simultaneously started. And the web searching page can automatically jump to the manual web searching page.

Fig. 11 and 12 are two examples of the "manual web search" page provided in the embodiment of the present application. As shown in fig. 11 and 12, the "manual web search" page may include one or more of the following items of information: "Manual search completion ratio" 406A, "searched networks" 406B, "searching networks" 406C, and "networks to be searched" 406D. The "manual network searching completion ratio" 406A may be in the form of a progress bar and a percentage shown in fig. 11, or may also be in the form of a progress ring and a percentage shown in fig. 12, which is not limited in this embodiment of the present application. In addition, in order to facilitate the user to know the network information and the network service quality of the network, the networks 1-4 shown in "searched network" 406B, "searching network" 406C, and "to-be-searched network" 406D in fig. 11 may be network information shown with operator names and network formats, such as "5G network of operator a", "4G network of operator B", "3G network of operator C", and "2G network of operator D" shown in fig. 12, so that the user can determine the network searching sequence and select the wireless network to be accessed according to the actual requirements, such as acceptable tariff, required data rate, and the like.

That is to say, in order to facilitate the user to know the manual network searching progress and/or the network searching result, the manual network searching method may further include the following steps:

and displaying the progress information of the manual network searching on a display screen of the terminal.

Wherein, the progress information may include one or more of the following items: the completion ratio of manual network searching, the network information of the searched network, the network information of the network being searched, the network information of the network to be searched, the network information of the searched network, and the like.

In the embodiment of the present application, when a high-priority service arrives, the terminal needs to immediately interrupt the manual network searching and then process the high-priority service. Therefore, the following steps are also required:

s302, interrupting the manual network searching and processing the first service.

And the priority of the first service is higher than that of the manual network searching.

The first service may be, for example, various services such as short message service, telephone service, game service, online audio and/or video playing, payment service, file downloading service, web browsing service, and the like, which is not limited in this embodiment of the present application. Here, it should be understood that the priority order of the services may be customized by the user, or may be set by the terminal manufacturer at the time of factory or later system maintenance, and the priority order of the services may be set based on factors such as urgency and instantaneity of the services.

Alternatively, when the manual network searching is interrupted, as shown in fig. 13, a prompt message may be displayed on the "manual network searching" page, such as replacing the prompt text "manual network searching completion ratio" with "manual network searching pause …". Of course, the "searched network" 406B, "the" searching network "406C, and the" to-be-searched network "406D, and their corresponding prompt text may also be adjusted to be gray.

In this embodiment of the application, after the first service is finished, the terminal may also resume the manual network search in this round. That is, the following steps need to be performed:

s303, after the first service is finished, continue to receive system messages of other cells.

In a possible design method, S303, after the first service is ended, continuing to receive system messages of other cells, may include the following steps:

and after the first service is finished, displaying prompt information on a display screen of the terminal. And the prompt information is used for prompting the user to select whether to resume executing the manual network searching. And responding to the user selection to resume the operation of manually searching the network, and continuously receiving system messages of other cells.

Or, optionally, the method for searching for a network manually may further include the following steps: and in response to the user selection, terminating the manual network searching operation and not receiving system messages of other cells.

Illustratively, as shown in fig. 14, after the first service is finished, a display of "do to continue to complete the manual network search? "dialog box 407A, in which 2 options are displayed: option "yes" 407B and option "no" 407C. If the user selects 'yes', the manual network searching in the current round is continued, and if the user selects 'no', the manual network searching in the current round is stopped.

It should be noted that, all the possible implementations described above are technical solutions for responding to the selection of whether to resume the operation action of the manual network search in the current round based on the prompt information by the user. It is easy to understand that, after the first service is ended, the manual network searching in the current round can be automatically resumed or terminated according to the pre-configured information. Therefore, in another possible design method, the method for manually searching for a web may further include the following steps:

and after the first service is finished, automatically receiving system messages of other cells.

It should be understood that the first cell in this embodiment may be one cell, or may be multiple cells, and the first cell and other cells may both be from a manual network searching cell list set in the terminal, only to distinguish that the system messages received before and after the manual network searching for the first service interruption are from different cells.

Optionally, when the first service is interrupted, the received system message of the first cell may be stored in a volatile memory (e.g., a register or a cache) in the baseband processor or the system chip, or may be stored in a non-volatile memory (e.g., a flash memory) connected to the system chip, and after the first service is ended, information stored in the memory may be read, and based on the stored information, the system messages of other cells may be continuously received. The GUI display content in the embodiment of the present application may display specific network searching information by reading the storage information in the memory.

Or, optionally, when processing the first service exceeds a time threshold, after the first service is ended, re-receiving the system message of the first cell.

It should be understood that the terminal may start a timer according to a network event that the terminal interrupts manual network searching and starts processing the first service, and the timeout duration of the timer is determined by the time threshold. The time threshold may be determined according to a round of complete manual network search, such as time consumed by full-system and full-band manual network search, and may be set to, for example, 1 minute, 2 minutes, 80 seconds, or the like, and may be manually set by a user on a GUI provided by a terminal, or may be dynamically set by a network through signaling, and may also be preset before the terminal leaves a factory or after the terminal enters a network, which is not limited in this embodiment of the present application. The timer may be a software timer, or a hardware timer, or a timer combining software and hardware. For example, if the time threshold is 1 minute, a built-in hardware timer is selected, the duration of the hardware timer is 1 second, a counter is set in the software code, the initial value of the counter is 59, the counter is decremented by 1 each time the hardware timer prompts for 1 second, when the counter becomes 0, the time threshold is considered to be reached, and after the first service is finished, the current manual network searching is automatically terminated.

Or, optionally, when the first service is ended, if the terminal leaves the area where the manual network searching is started, automatically terminating the manual network searching.

For example, the terminal may determine whether the terminal has left the area where the manual network search was initiated according to the change of the geographic location sensed by its location sensor. Exemplary, it may be embodied as: the position sensor sends the position information of the terminal, the application processor receives the position information and forwards the position information to the baseband processor, and the baseband processor judges whether the terminal leaves the area where the manual network searching is started according to the comparison result of the position information and the area where the manual network searching is started. Alternatively, the application processor may determine whether the terminal has left the area where the manual network search is initiated based on the location information sent by the location sensor, and send the determination result to the baseband processor in the form of indication information (e.g., 0, 1 indication bit or high-low level). Or, the location sensor may directly determine whether the terminal leaves the area where the manual network search is started, and send instruction information based on the determination result, and the baseband processor may determine whether the terminal leaves the area where the manual network search is started according to the instruction information.

Illustratively, the position sensor may be a Global Navigation Satellite System (GNSS), such as a Global Positioning System (GPS) module or a beidou positioning module, and the position information may be geographical position information, such as latitude and longitude.

It can be understood that there are many possible embodiments for determining whether the terminal leaves the area where the manual network search is initiated, for example, determining that the terminal leaves the area where the manual network search is initiated as soon as the geographical location of the terminal changes. Or when the geographical position of the terminal changes and exceeds a certain threshold value, the terminal is judged to leave the area where the manual network searching is started.

The position sensor may be replaced by a gyro sensor or an acceleration sensor. And judging whether the motion state of the terminal changes or not through the sensor so as to presume whether the terminal leaves the area where the manual network searching is started or not.

It should be noted that the preconfigured information for automatically restoring or automatically terminating the manual network search in the current round may be configured before the terminal leaves the factory or during system upgrade, or may be dynamically configured by a network device, such as a base station, when the terminal accesses the wireless network, or may be preset by a user when the manual network search is started or before the manual network search is started, which is not limited in the embodiment of the present application.

Alternatively, when the "auto select" switch 405 shown in fig. 10 is disabled, instead of immediately initiating the manual search, another GUI when the "auto select" switch 405 is disabled as shown in fig. 15 may be displayed. As shown in fig. 15, the setting items on the GUI may include a "start manual network search" switch 410, and one or more manual network search automatic recovery/termination condition setting items, such as a "maximum interruptible time length" 408 and a "position update automatic termination" switch 409. The "start manual network searching" switch 410, "maximum interruptible time length" 408, and "automatically terminate after location update" switch 409 are only active when the "automatically select" switch 405 is disabled.

Illustratively, as shown in fig. 15, the user may manually set the value of the "maximum interruptible time length" according to the time threshold or the estimated time spent in one or more previous manual searches, such as "2 minutes" shown in fig. 15. And when the manual network searching is interrupted by the high-priority service and the processing time of the high-priority service is longer than or equal to 2 minutes, the manual network searching in the current round is not resumed, namely, the manual network searching in the current round is automatically terminated.

Illustratively, the terminal position may be obtained by a positioning service (positioning services) of a global navigation system (GNSS), or may be obtained by receiving a Positioning Reference Signal (PRS) transmitted by a network device. Terminal locations include, but are not limited to: latitude and longitude, physical cell identification of the serving cell, base station identification, serving area identification, tracking area identification, or other information that may be used to indicate the location of the terminal. Correspondingly, the "location update" means that the current location of the terminal is not in the same area as the location of the terminal when the manual network searching is started. For example, the distance between the two locations is greater than a certain distance threshold, or located in different physical cells, coverage areas of different base stations, different service areas, different tracking areas, and so on, respectively. It is easy to understand that, after the location of the terminal is updated, since the wireless channel may have changed greatly, the result of the manual network search interrupted by the high-priority service may no longer have a referential meaning, and therefore, it is necessary to automatically terminate the round of manual network search, such as clearing the network search progress and the network search result.

It should be noted that, at each stage before the manual network searching is terminated automatically or manually, or before the manual network searching is finished normally, the progress information and the network searching result of the manual network searching can be displayed, so that the user can conveniently perform the next operation.

It is easy to understand that if a user selects a manual access from a searched network list and successfully accesses the network list in the manual network searching process, that is, the purpose of manual network searching is achieved, the manual network searching in the current round can be automatically terminated, so as to save resources and power consumption. For example, as shown in fig. 12, if the user clicks "5G network of operator a" in the "searched network" list and accesses successfully in the manual network searching process, the manual network searching in the current round may be automatically terminated.

The method for manually searching for a network provided by the embodiment of the present application is described in detail above with reference to fig. 3 to fig. 15. The following describes in detail a communication device and a terminal that can perform the above-mentioned method for manually searching a network according to an embodiment of the present application with reference to fig. 16 to 18.

Fig. 16 is a first schematic structural diagram of a communication device according to an embodiment of the present application. The communication device can be applied to the terminal of the communication system shown in fig. 1, and the terminal is supported to execute the method for manually searching the network shown in fig. 3. For convenience of explanation, fig. 16 shows only the main components of the communication apparatus.

As shown in fig. 16, the communication apparatus 1600 includes: a processor 1601 and input/output ports 1602. The processor 1601 and the input/output port 1602 may be connected via a communication line 1603, such as a bus.

The input/output port 1602 is configured to receive a system message of a first cell when a manual network search is started. The system message of the first cell carries configuration information of the first cell.

And the processor 1601 is used for interrupting the manual network searching and processing the first service. And the priority of the first service is higher than that of the manual network searching.

The input/output port 1602 is further configured to continue to receive system messages of other cells after the first service is ended.

In a possible design, the processor 1601 is further configured to display a prompt message on a display screen of the terminal where the communication device 1600 is located after the first service is ended. And the prompt information is used for prompting the user to select whether to resume executing the manual network searching. Accordingly, the input/output port 1602 is further configured to continue receiving system messages of other cells after the user selects to resume the manual network search.
