[0062] The example embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following example embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0063] In the network searching process, the terminal usually searches wireless networks of different network standards in a serial search manner in the order of 5G->4G->3G->2G, and searches until a wireless network is found. However, due to the insufficient coverage of the 5G network, the terminal may spend a long time searching for the 5G network, or even fail to search for the 5G network, and then search for the 4G network, which results in a slow network searching speed and a long network searching time of the terminal.

[0064] In order to improve the network searching speed of the terminal, the network searching method of the terminal is optimized in the related art, and the 5G network is searched in the background after the 4G network is successfully registered by searching the 4G network first. However, this method requires the terminal to camp on the 4G network first, which results in a slow connection between the terminal and the 5G network.

[0065] Therefore, the present disclosure provides a network searching method. Figure 1 is a network searching method flow according to an example embodiment of the present disclosure Figure 1 As shown in Figure 2 the method comprises the following steps:

[0066] Step S101, searching different wireless networks of at least two communication standards in parallel;

[0067] Step S102, when at least one wireless network is searched, starting a registration process of registering to the wireless network searched first.

[0068] In the present disclosure, the network searching method can be applied to a terminal, and the terminal can be any intelligent electronic device with mobile communication function, such as a smart phone, a tablet computer, a smart watch, and the like.

[0069] In step S101, the terminal initiates a parallel search of different wireless networks of at least two communication modes at the same time.

[0070] In the embodiments of the present disclosure, the terminal can be a multi-mode terminal capable of supporting multiple network modes.

[0071] It should be noted that the network mode refers to the type of network; the network modes that the terminal can support at present mainly include: 2G network modes, such as Global System for Mobile Communication (GSM) and Code Division Multiple Access (CDMA); 3G network modes, such as Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA); 4G network modes, such as Time Division Long Term Evolution (TF-LTE), Frequency Division Duplexing Long Term Evolution (FDD-LTE); 5G network mode; here, only common network modes are listed, and with the development of the network, the network mode in the embodiments of the present disclosure can also include The 6th-Generation (6G) network mode and other network modes, and in actual application, flexible adjustment needs to be made according to the specific application scenario.

[0072] In the embodiments of the present disclosure, the parallel search of different wireless networks of at least two communication modes can be performed according to a preset network search strategy.

[0073] Here, the at least two communication modes searched by the terminal can be wireless networks of at least two communication modes supported by the terminal.

[0074] Here, the preset search strategy can be set according to actual needs. For example, the preset network search strategy can be to search the 5G network in the mobile network coverage range where the terminal is currently located while searching the 4G, 3G and 2G networks in the mobile network coverage range where the terminal is currently located one by one.

[0075] In step S102, when at least one wireless network is searched, the first searched wireless network is determined as a network to be registered, a network registration is initiated to the network to be registered, and thus camping on the network to be registered is realized.

[0076] In some embodiments, the registration procedure of the wireless network can include:

[0077] According to the at least one searched wireless network, an attach request is sent to the wireless network, wherein the identity information stored in the user identification module of the terminal is carried in the attach request.

[0078] An attach accept response returned after the identity authentication of the terminal by the wireless network is received.

[0079] The network parameter information of the wireless network is acquired.

[0080] Based on the network parameter information of the wireless network, a cell under the wireless network is camped on.

[0081] In the embodiments of the present disclosure, the identity information stored in the user identification module can include an International Mobile Subscriber Identity (IMSI), wherein the IMSI is used to distinguish mobile users. The network parameter information of the wireless network can include Public Land Mobile Network (PLMN) information of the wireless network.

[0082] The terminal acquires the Public Land Mobile Network (PLMN) information of the wireless network, and camps on a cell under the wireless network according to the PLMN information.

[0083] In some embodiments, the method can further include:

[0084] It is determined whether the terminal has a network search requirement.

[0085] The parallel search of different wireless networks of at least two communication modes in step S101 can include:

[0086] If the terminal has a network search requirement, different wireless networks of at least two communication modes are searched in parallel.

[0087] In the embodiments of the present disclosure, the determination of whether the terminal has a network search requirement can include at least one of the following:

[0088] If the terminal switches from a power-off state to a power-on state, it is determined that the terminal has a network search requirement.

[0089] or the terminal enters a network coverage area from a non-network coverage area, it is determined that the terminal has a network search requirement;

[0090] If the terminal exits from a mode without registration to a network, such as a flight mode, it is determined that the terminal has a network search requirement.

[0091] For example, when the terminal is in a power-off state, the terminal is triggered by a specific key (e.g., a power key) to perform a power-on start process, and at this time, the terminal has a network search requirement.

[0092] Or, when the terminal moves from a non-network signal coverage area to a network signal coverage area, at this time, the terminal has a network search requirement.

[0093] Or, when the terminal switches from a flight mode to a normal mode, at this time, the terminal has a network search requirement.

[0094] For example, when the terminal is in a power-on start state, or when the terminal switches from a flight mode to a normal mode, an application processor (AP) of the terminal sends a network search instruction to a communication processor (CP) in the terminal, the CP receives the network search instruction, and searches for different wireless networks of at least two communication modes in parallel; and after searching for at least one wireless network, the terminal is camped on, at this time, the terminal is successfully connected to the wireless network.

[0095] In some embodiments, as shown in Figure 2 , a network search method is shown according to an embodiment of the present disclosure Figure 2 , the method can further include: Figure 3

[0096] Step S103, when a first wireless network of a first communication mode is searched, a second wireless network with a higher priority than the first wireless network is searched; wherein the second wireless network is a wireless network of a second communication mode in the communication mode.

[0097] The priority of different wireless networks can be predetermined, for example, determined according to user input or determined according to network performance and / or network properties of the wireless network and the like.

[0098] ​For example, a terminal supports both 4G network and 5G network. If it is determined according to network performance and network attribute, the priority of 5G network can be set higher than that of 4G network, considering that 5G network has larger system bandwidth and / or can provide higher transmission rate. However, in some cases, due to the cost of 5G network, the terminal can receive user input of using 4G network preferentially in user interface, and thus the priority of 4G network can be higher than that of 5G network.

[0099] In an embodiment of the present disclosure, the performance index of the second wireless network is superior to that of the first wireless network. Here, the performance index includes but is not limited to transmission rate, delay, capacity, Quality of Service (QoS) of service, and time or frequency division multiplexing manner, etc.

[0100] Since the priority of the second wireless network is higher than that of the first wireless network, it indicates that the current second wireless network is a network more suitable for the terminal to camp on or a network more willing for the terminal to camp on, and thus it is still expected to camp in the second wireless network as much as possible in the case that the terminal supports the second wireless network. Therefore, if the wireless network searched first by the terminal is the first wireless network of the first communication standard in the communication standards, the terminal can start a registration process of registering to the first wireless network, and continue searching for the second wireless network. That is, the searching for the second wireless network is not stopped in the registration process of registering to the first wireless network.

[0101] In this way, the network search speed can be improved, and it is ensured to camp in the second wireless network with higher priority as much as possible.

[0102] In other embodiments, if the wireless network searched first by the terminal is the second wireless network of the second communication standard in the communication standards, the terminal starts a registration process of registering to the second wireless network, and stops searching for the first wireless network.

[0103] That is, in an embodiment, if the first searched wireless network is a wireless network with high priority, a registration process of registering to the wireless network with high priority is started, and the search for a wireless network with lower priority than the currently registering wireless network is stopped, which on one hand reduces unnecessary network search, and on the other hand reduces the terminal power consumption overhead and the occupation of software and hardware resources caused by network search.

[0104] In some embodiments, as shown in Figure 3 , the network search method according to an embodiment of the present disclosure is shown in Figure 3 , and the method further includes: Figure 4

[0105] ​Step S104, after searching for the second wireless network, register to the second wireless network.

[0106] In one embodiment of the present disclosure, after searching for the second wireless network, the terminal can register to the second wireless network while maintaining the connection to the first wireless network, realizing the multi-wireless network connection of the terminal.

[0107] In another embodiment of the present disclosure, after searching for the second wireless network, the terminal can disconnect the network connection with the first wireless network and register to the second wireless network.

[0108] Since the terminal is still camping in the first wireless network at this time, when searching for the second wireless network, the terminal can disconnect the network connection with the first wireless network, switch to the second wireless network, thereby improving the network usage effect, greatly realizing the highest network configuration of the terminal, reducing resource waste, and improving the user experience.

[0109] In some other embodiments, the method further comprises:

[0110] When successfully registering to the second wireless network, record the frequency point information of the second wireless network and the current location information of the terminal.

[0111] In the embodiment of the present disclosure, when the terminal successfully registers to the second wireless network, the frequency point of the second wireless network and the current location information of the terminal are recorded; and based on the above recorded content, the frequency point distribution information including the frequency point of the second wireless network and the location information of the terminal is formed; the frequency point distribution information can be stored in the terminal or in the cloud server connected to the terminal.

[0112] When the terminal performs network search, the current location information of the terminal is acquired; according to the current location information, it is determined whether the position indicated by the current location information is a coverage area of the second wireless network; if the position indicated by the current location information is a coverage area of the second wireless network, the frequency point of the second wireless network corresponding to the current location information is queried; and based on the frequency point, the second wireless network is searched.

[0113] In this way, by recording the frequency point of the second wireless network associated with the location information of the terminal, the terminal can only search for specific frequency points during network search, improving the network search speed and saving the network search time.

[0114] In some embodiments, the step S104 of registering to the second wireless network after searching for the second wireless network can comprise:

[0115] if the terminal has registered to the first wireless network when searching for the second wireless network, starting a deregistration procedure of deregistering to the first wireless network;

[0116] or,

[0117] if the terminal has not registered to the first wireless network when searching for the second wireless network, stopping a registration procedure of registering to the first wireless network.

[0118] In the embodiments of the present disclosure, the terminal first searches for a first wireless network, and starts a registration procedure of registering to the first wireless network, and then searches for a second wireless network. At this time, the terminal has completed the registration procedure of registering to the first wireless network. Therefore, the terminal initiates the registration procedure of registering to the second wireless network before starting the registration procedure of registering to the second wireless network, simultaneously with initiating a deregistration procedure of deregistering to the first wireless network or after deregistering to the first wireless network.

[0119] Or, the terminal has not completed the registration procedure of registering to the first wireless network. Therefore, the terminal needs to stop the registration procedure of registering to the first wireless network and start the registration procedure of registering to the second wireless network.

[0120] In some embodiments, the system bandwidth of the first wireless network of the first standard is smaller than the system bandwidth of the second wireless network of the second standard.

[0121] In the embodiments of the present disclosure, for example, the data amount of data transmission per unit time of the terminal when using the second wireless network is better than the data amount of data transmission of the terminal when working in the first wireless network. Or, the data transmission rate of the terminal when using the second wireless network is better than the data transmission rate of the terminal when working in the first wireless network.

[0122] Exemplarily, the second wireless network can be a 5G network; and the first wireless network can include at least one of a 4G network, a 3G network or a 2G network.

[0123] It should be noted that in the embodiments of the present disclosure, it is not limited that the second wireless network is a 5G network and the first wireless network is a 4G network, a 3G network or a 2G network. For example, the second wireless network can be a 6G network, and the first wireless network can be a 5G network, a 4G network, a 3G network or a 2G network. The embodiments of the present disclosure are not limited.

[0124] Since the coverage of the 5G network is not comprehensive, the embodiments of the present disclosure can improve the network search speed of the terminal as much as possible, reduce the network search time, and use the 5G network to a greater extent, reduce unnecessary network search, improve the network performance of the terminal, and improve the user experience.

[0125] In some embodiments, the method further comprises:

[0126] determining a first frequency band for searching the first wireless network and a second frequency band for searching the second wireless network;

[0127] The step S101 of searching different wireless networks of at least two communication modes in parallel can include:

[0128] The step S101 of searching different wireless networks of at least two communication modes in parallel can include:

[0129] The first frequency band can include one or more frequency points of the second wireless network. The second frequency band can include one or more frequency points of the second wireless network.

[0130] In the embodiments of the present disclosure, when the terminal satisfies the network search condition, the network operator corresponding to the user identification module of the terminal can be determined based on the user identification module, and the first frequency band corresponding to the first wireless network and the second frequency band corresponding to the second wireless network can be determined according to the working frequency bands that the network operator can support, the first mode and the second mode.

[0131] Here, the user identification module includes but is not limited to a Subscriber Identity Module (SIM) card or a Universal Subscriber Identity Module (USIM) card. The user identification module can be used to store the identity information of the user and the network operator information, and the network operator information includes but is not limited to the working frequency bands that the network operator can support.

[0132] It should be noted that different user identification modules correspond to different operators, for example, mobile, Unicom or telecom, and each operator can provide network services of multiple network modes, and the corresponding frequency bands are different; the first frequency band and the second frequency band are determined according to the SIM card information, the first mode and the second mode.

[0133] In some embodiments of the present disclosure, the working frequency bands of all network operators can be preset in the terminal. For example, the working frequency bands of mobile, Unicom and telecom are preset respectively, and then in the process of use, the working frequency bands supported by the network operator corresponding to the user identification module are obtained according to the network operator.

[0134] The step S101 of searching different wireless networks of at least two communication modes in parallel can include:

[0135] The step S101 of searching different wireless networks of at least two communication modes in parallel can include:

[0136] In some embodiments, the method further comprises:

[0137] When the terminal does not support simultaneous reception of multiple frequency points, the second wireless network with higher priority is searched first according to the priority of different communication systems.

[0138] In some embodiments, since the terminal generally supports simultaneous reception of multiple frequency points if it supports simultaneous transmission of multiple frequency points, if it is determined that the terminal supports simultaneous transmission of multiple frequency points, it is determined that the terminal supports simultaneous reception of multiple frequency points.

[0139] Meanwhile, if it is determined that the terminal does not support simultaneous transmission of multiple frequency points, it is further determined whether it supports simultaneous reception of multiple frequency points.

[0140] In one embodiment, the method further comprises:

[0141] If the terminal supports simultaneous transmission of multiple frequency points, after the terminal registers to the first wireless network and searches the second wireless network, it is determined whether to perform the de-registration process of the first wireless network according to the camping strategy.

[0142] Or,

[0143] If the terminal supports simultaneous transmission of multiple frequency points, after the terminal registers to the first wireless network and searches the second wireless network, it is determined whether to perform the de-registration process of the first wireless network according to the camping strategy.

[0144] Exemplarily, the camping strategy at least includes at least one of the following:

[0145] Single network registration strategy, i.e. the terminal camps to only one wireless network at a time, and usually camps to the successfully searched wireless network with the highest priority, which can save the power consumption of the terminal as much as possible;

[0146] Multi-registration strategy, i.e. the terminal can camp to multiple wireless networks at a time to ensure that the terminal obtains the maximum communication bandwidth; at this time, the terminal can camp to the first wireless network and the second wireless network at the same time.

[0147] Of course, the above are examples of the camping strategy, and the specific implementation is not limited thereto.

[0148] In some embodiments, the method further comprises:

[0149] If no wireless network is searched within a preset time, the frequency points searched in the first frequency band and / or the second frequency band are adjusted.

[0150] In the embodiments of the present disclosure, the preset time can be set according to actual needs, for example, 60 seconds or 30 seconds, etc., which is long enough for the terminal to receive the frequency point of the network at the coverage of the wireless network.

[0151] Since each frequency band can contain multiple frequency points, when it is detected that the continuous search time of the terminal based on the current frequency point exceeds the preset time, it indicates that the terminal has not searched for a signal for a long time; the frequency point searched in the first frequency band and / or the second frequency band can be adjusted, and the search for the first wireless network and / or the second wireless network can be re-initiated based on the adjusted frequency point; so as to avoid that the terminal cannot access the network for a long time and affect the normal use of the user.

[0152] In some embodiments, if a wireless network is not searched within a preset time period, adjusting the frequency point searched in the first frequency band and / or the second frequency band can include:

[0153] If a wireless network is not searched within a preset time, a plurality of frequency points contained in the first frequency band and / or the second frequency band are acquired.

[0154] Based on the signal strength of the plurality of frequency points, a target frequency point is determined.

[0155] In the embodiments of the present disclosure, the signal strength of the frequency band can include a received signal strength indication (RSSI) value; the RSSI value of the frequency point can be directly acquired when the frequency point is scanned.

[0156] By acquiring the signal strength of the plurality of frequency points contained in the first frequency band and / or the second frequency band, the plurality of frequency points are sorted based on the signal strength; and according to the sorting result, a target frequency point is determined.

[0157] It should be noted that the signal strength of the frequency point where the cell is located is higher than the signal strength of other idle frequency points; according to the signal strength of the frequency point, the frequency point with higher signal strength is preferentially searched, the working frequency point where the cell is located can be more easily sent, and thus the speed of network search is improved.

[0158] In some embodiments, the parallel search of different wireless networks of at least two communication modes in S101 can include:

[0159] The first radio frequency module is used to search the first wireless network, and the second radio frequency module is used to search the second wireless network.

[0160] In the embodiments of the present disclosure, the terminal includes a first radio frequency module and a second radio frequency module, and after determining to search for a first frequency band of the first wireless network and a second frequency band of the second wireless network, the first radio frequency module and the second radio frequency module are used to search for the first wireless network and the second wireless network in parallel based on the first frequency band and the second frequency band.

[0161] It should be noted that in the embodiments of the present disclosure, the terminal includes at least two independent radio frequency modules, and the radio frequency modules can work simultaneously without time division; and the radio frequency modules do not affect each other.

[0162] The present disclosure also provides the following embodiments:

[0163] Figure 1 A network search method flow is shown according to an exemplary embodiment Figure 5 , Figure 2 A network search method flow is shown according to an exemplary embodiment Figure 4 As shown in Figure 5 , Figure 6 , the method includes:

[0164] Step S401, determining whether the terminal has a network search requirement, if the terminal has a network search requirement, searching for different wireless networks of at least two communication systems in parallel;

[0165] In the present example, the terminal can be a terminal supporting 4G-5G dual connectivity (E-UTRA-NR Dual Connetivity, EN-DC). As shown in Figure 6 , Figure 7 A terminal structure diagram is shown according to an exemplary embodiment. The terminal includes a first radio frequency module, a second radio frequency module, a 4G protocol stack module, a 5G protocol stack module, a network search management module, and a frequency band management module; wherein the first radio frequency hardware can be a 2G, 3G or 4G radio frequency module; the second radio frequency hardware can be a 5G radio frequency module. The first radio frequency module and the second radio frequency module can search for networks in parallel.

[0166] The determination of whether the terminal has a network search requirement can include at least one of the following: if the terminal is in a power-on startup state, it is determined that the terminal has a network search requirement; or if the terminal is in an out-of-service (OOS) state, it is determined that the terminal has a network search requirement.

[0167] Exemplarily, it is judged whether the terminal is in a power-on startup state or an OOS state, if the terminal is in a power-on startup state or an OOS state, the network search management module initiates a network search request to the 4G protocol stack module and the 5G protocol stack module;

[0168] In some embodiments, before searching different wireless networks of the at least two communication standards in parallel, the method further comprises:

[0169] determining a first frequency band for searching a 4G network and a second frequency band for searching a 5G network;

[0170] In this example, the 4G network is the first wireless network in one or more embodiments described above; the 5G network is the second wireless network in one or more embodiments described above. The system bandwidth of the 4G network is less than that of the 5G network.

[0171] The 4G protocol stack module and the 5G protocol stack module send a frequency band acquisition request to the frequency band management module in the terminal; the frequency band management module determines a first frequency band for searching a 4G network and a second frequency band for searching a 5G network according to the degree of concurrency. The frequency band management module sends a frequency band acquisition response carrying the first frequency band and the second frequency band to the 4G protocol stack and the 5G protocol stack respectively; the 4G protocol stack and the 5G protocol stack send network search instructions to the 4G radio frequency module and the 5G radio frequency module in the terminal based on the first frequency band and the second frequency band; and the 4G radio frequency module and the 5G radio frequency module are used to search for wireless signals transmitted by any frequency point in the first frequency band and the second frequency band in parallel.

[0172] In some embodiments, the method further comprises:

[0173] determining full concurrency frequency band information and partial concurrency frequency band information according to frequency band distribution information of the 4G network and the 5G network;

[0174] The determination of the first frequency band for searching the 4G network and the second frequency band for searching the 5G network comprises:

[0175] determining the first frequency band for searching the 4G network and the second frequency band for searching the 5G network according to the full concurrency frequency band information and the partial concurrency frequency band information.

[0176] In this example, the frequency band management module obtains a full concurrency frequency band list and a partial concurrency frequency band list according to the radio frequency configuration information; here, the full concurrency frequency band list is used to record the frequency bands of the wireless networks that can work completely in parallel; and the partial concurrency frequency band list is used to record the frequency bands of the wireless networks that can work partially in parallel.

[0177] Step S402, if the terminal searches the 4G network first, start the registration process of registering to the 4G network, and continue to search the 5G network with higher priority than the 4G network;

[0178] It should be noted that when the terminal registers with the network side, the terminal can send a connection request to the network side; after the base station receives the connection request, the base station feeds back response information to the terminal. After the terminal receives the response information from the network side, the terminal sends an acknowledgement message indicating successful access or a non-acknowledgement message indicating failed access, thereby completing the registration process. After the terminal successfully accesses the network side, the terminal can perform a download or upload data service.

[0179] Since the performance indicators of the 5G network are better than those of the 4G network, when registering with the network, the terminal is preferably camped in the 5G network. Thus, if the terminal first searches for a 4G network, the terminal can start a registration process for registering with the 4G network and continue searching for a 5G network.

[0180] In some embodiments, the method further comprises:

[0181] If the terminal starts the registration process for registering with the 4G network and does not search for a 5G network within a preset time, the terminal stops searching for the 5G network.

[0182] In this example, if no 5G network is searched based on the searched frequency bands in the second frequency band, it is indicated that the terminal can not be in the coverage of the 5G network, and thus the terminal stops searching for the 5G network and camps in the 4G network.

[0183] In some embodiments, when the terminal first searches for a 4G network, the terminal starts a registration process for registering with the 4G network and continues searching for a 5G network having a higher priority than the 4G network, comprising:

[0184] If the terminal first searches for a 4G network, the concurrent state of the first frequency band and the second frequency band is determined.

[0185] If the concurrent state indicates that the first radio frequency module and the second radio frequency module can completely concurrently work in the first frequency band and the second frequency band, the terminal starts a registration process for registering with the 4G network and continues searching for the 5G network using the second radio frequency module.

[0186] Alternatively, if the concurrent state indicates that the first radio frequency module and the second radio frequency module can partially concurrently work in the first frequency band and the second frequency band, the terminal starts a registration process for registering with the 4G network; and after successful registration with the 4G network, the terminal continues searching for the 5G network using the second radio frequency module.

[0187] Step S403: After searching for a 5G network, the terminal registers with the 5G network.

[0188] In the example, when the terminal searches for the 5G network, since the terminal is still camped in the 4G network at this time, the terminal needs to disconnect the network connection with the 4G network first, and then start the registration procedure for registering to the 5G network.

[0189] In some embodiments, after searching for the 5G network, the registration to the 5G network comprises:

[0190] If the terminal has registered to the 4G network when searching for the 5G network, a deregistration procedure for deregistering to the 4G network is started;

[0191] Or, if the terminal has not registered to the 4G network when searching for the 5G network, the registration procedure for registering to the 4G network is stopped.

[0192] In the example, if the terminal has completed the registration procedure for the 4G network, at this time, the terminal has established a network connection with the 4G network, before the terminal starts the registration procedure for the 5G network, the terminal needs to initiate a deregistration procedure for the 4G network first, disconnects the connection with the 4G network, and then reinitiates the registration procedure for the 5G network. If the terminal has not completed the registration procedure for the 4G network, at this time, the terminal has not established a network connection with the 4G network, the terminal can stop the registration procedure for the 4G network and start the registration procedure for the 5G network instead.

[0193] In step S404, if the terminal searches for the 5G network first, a registration procedure for registering to the 5G network is started, and the search for the 4G network is stopped.

[0194] In the example, if the terminal can search for the 5G network first, the terminal is camped in the 5G network preferentially, and the search for the 4G network is stopped, which can not only ensure a high transmission speed of the network and improve the user experience, but also reduce unnecessary searches.

[0195] In step S405, if no wireless network is searched for within a preset time, the frequency point searched in the first frequency band and / or the second frequency band is adjusted.
