[0001] The present application relates to the network technical field, and particularly relates to a network searching method of terminal equipment, terminal equipment and storage medium. BACKGROUND

[0002] With the development of communication technology, terminal equipment capable of installing multiple user identification cards is more and more favored by users, such as smart phones capable of installing multiple SIM (Subscriber Identity Module) cards. In the prior art, after the terminal equipment with multiple user identification cards is started, the multiple user identification cards will perform frequency band by frequency band network searching in the respective corresponding frequency bands to find a cell that can be accessed in the current frequency band. However, there are often repeated frequency bands between different user identification cards, and multiple user identification cards will perform network searching on one frequency band respectively, which is low in network searching efficiency, consumes more time, and leads to poor user experience. Therefore, a method for improving the network searching efficiency of terminal equipment is urgently needed. SUMMARY

[0003] Embodiments of the present application provide a network searching method of terminal equipment, terminal equipment and storage medium, which aims to improve the network searching efficiency of terminal equipment.

[0006] if the target cell is searched in the preset frequency band, determining whether the target cell belongs to a legal cell of the second user identification card;

[0007] if the target cell belongs to the legal cell of the second user identification card, sending a camping instruction to the second wireless communication module to instruct the second user identification card corresponding to the second wireless communication module to camp in the target cell.

[0010] The embodiments of the present application provide a cell search method of a terminal device, a terminal device and a storage medium. The embodiments of the present application determine whether there is a target cell on a preset frequency band by controlling the first wireless communication module to search for a cell on the preset frequency band, wherein the preset frequency band belongs to the frequency band corresponding to the first subscriber identity card and belongs to the frequency band corresponding to the second subscriber identity card. If the target cell is searched on the preset frequency band, it is determined whether the target cell belongs to the legal cell of the second subscriber identity card. If the target cell belongs to the legal cell of the second subscriber identity card, a camping instruction is sent to the second wireless communication module to instruct the second subscriber identity card corresponding to the second wireless communication module to camp in the target cell.

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort should fall within the protection scope of the present application.

[0016] The flowchart shown in the drawings is only an example and does not necessarily include all the contents and operations / steps, nor does it necessarily be executed in the described order. For example, some operations / steps can be further decomposed, combined or partially merged, and thus the actual execution order can be changed according to the actual situation.

[0017] It should be understood that the terms used in the present application specification are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the present application specification and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0018] The embodiments of the present application provide a network searching method of a terminal device, a terminal device and a storage medium. The network searching method of the terminal device can be applied to a mobile terminal, which can be a mobile phone, or an electronic device such as a tablet computer, a notebook computer, a desktop computer, a personal digital assistant and a wearable device installed with a subscriber identification card.

[0019] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0020] Please refer to Figure 1 , Figure 1 A step flowchart of a network searching method of a terminal device provided by an embodiment of the present application is shown.

[0021] As shown in Figure 1 , the network searching method of the terminal device includes steps S101 to S103.

[0022] Step S101, controlling the first wireless communication module to search for a network in a preset frequency band, and determining whether there is a target cell on the preset frequency band; wherein the preset frequency band belongs to the frequency band corresponding to the first subscriber identification card and belongs to the frequency band corresponding to the second subscriber identification card.

[0023] Exemplarily, the user identification card can be a SIM card, which can be, for example, a physical SIM card or a virtual SIM card (e.g., vSIM, eSIM), and the like, which can be used to access a Global System for Mobile Communications (GSM) network or a Universal Mobile Telecommunications System (UMTS) network, and the like, without limitation.

[0024] Exemplarily, the embodiments provided in the present application are used in a terminal device including a first wireless communication module and a second wireless communication module, and the first wireless communication module and the second wireless communication module correspond to a first user identification card and a second user identification card, respectively. Of course, it is not limited to this, and the terminal device can also include a third wireless communication module corresponding to a third user identification card, without limitation.

[0025] The wireless communication module can be a Modem. When the terminal device is powered on for the first time or roams to search for a network, the first wireless communication module and the second wireless communication module respectively initiate network search and registration of the user identification cards corresponding thereto. In the related art, when the terminal device including two user identification cards searches for a network, the first wireless communication module corresponding to the first user identification card searches for a network on a frequency band supported by the first user identification card, and the second wireless communication module corresponding to the second user identification card also searches for a network on a frequency band supported by the second user identification card. Since the frequency band supported by the first user identification card and the frequency band supported by the second user identification card can have overlapping frequency band ranges, the search time of the two user identification cards in the terminal device is long, and the search frequency bands are repeated.

[0026] Exemplarily, the wireless access technologies supported by the first wireless communication module include GSM, WCDMA, LTE, NR, and the like, and the wireless access technologies supported by the second wireless communication module include GSM, WCDMA, LTE, NR, and the like.

[0027] In some embodiments, the determining whether there is a target cell on the preset frequency band includes: determining a cell on the preset frequency band that meets a preset condition as the target cell.

[0028] Exemplarily, a cell refers to an area covered by a base station or a part of a base station in a cellular mobile communication system. A frequency band contains multiple cells, and a mobile terminal needs to search for a network in each frequency band through a wireless communication module to determine the cells contained in the frequency band.

[0029] For example, in order to ensure the user experience and prevent the user identification card from camping on a cell with poor signal quality, a cell on the preset frequency band that meets certain camping conditions is determined as a target cell in which the user identification card can camp.

[0030] In some embodiments, the preset condition comprises an S criterion.

[0031] For example, the camping condition can be set according to actual needs, for example, the camping condition can be an S criterion. The S criterion specifies the signal receiving power and the signal quality of the target cell, for example, requires that the receiving power Srxlev of the target cell > 0 dB and the signal quality Squal of the target cell > 0 dB, and the cell that meets the above conditions is determined as the target cell. Of course, it is not limited to this, and the camping condition is not limited herein.

[0032] Please refer to Figure 2 , Figure 2 Another step flow diagram of a network searching method of a terminal device provided by an embodiment of the present application is shown.

[0033] As shown in Figure 2 In some embodiments, before the method controls the first wireless communication module to search for a network on a preset frequency band and determines whether there is a target cell on the preset frequency band, the method further comprises: step S201, obtaining the identification card identifiers of the first user identification card and the second user identification card; step S202, determining the first frequency band corresponding to the first user identification card and the second frequency band corresponding to the second user identification card according to the identification card identifiers; and S203, determining the intersection of the first frequency band and the second frequency band as the preset frequency band.

[0034] For example, the user identification cards installed in the terminal device can be user identification cards of the same operator or user identification cards of different operators. The terminal device stores a frequency band list supported by each operator, and the terminal device can determine the frequency bands supported by the first user identification card and the second user identification card through the frequency band list, and then determine the frequency band supported by both the first user identification card and the second user identification card as the preset frequency band. Of course, in the case that the terminal device is installed with a third user identification card, the preset frequency band can also be the frequency band supported by both the first user identification card and the third user identification card, or the frequency band supported by both the second user identification card and the third user identification card, which is not limited herein.

[0035] For example, when the first user identification card assists the second user identification card in searching for a network or the second user identification card assists the first user identification card in searching for a network, the frequency band supported by both the first user identification card and the second user identification card is determined as the preset frequency band; when the first user identification card assists the third user identification card in searching for a network or the third user identification card assists the first user identification card in searching for a network, the frequency band supported by both the first user identification card and the third user identification card is determined as the preset frequency band; and the like, which will not be repeated here.

[0036] For example, assuming that the frequency bands supported by the first user identification card include {band1, band2, band3}, the frequency bands supported by the second user identification card include {band2, band3, band4}, the preset frequency band for the first user identification card and the second user identification card includes {band2, band3}, where band1, band2, band3, and band4 represent different frequency bands. Of course, if band3 and band4 are different frequency bands with an intersection, the intersection of band3 and band4 can also be set as the preset frequency band, which is not limited here.

[0037] For example, when the frequency bands supported by the operator change or the user identification card installed in the terminal device changes, the frequency band list is updated. For example, a new user identification card of an operator is inserted into the terminal device, and the terminal device can obtain the frequency bands supported by the operator and store the frequency bands into the frequency band list.

[0038] For example, by updating the frequency band list and determining the preset frequency band according to the first frequency band and the second frequency band, the network searching method of the terminal device provided by the present application can determine the preset frequency band that can be shared according to the actual situation, and the flexibility of network searching of the terminal device is improved.

[0039] In step S102, if the target cell is searched on the preset frequency band, it is determined whether the target cell belongs to the legal cell of the second user identification card.

[0040] For example, after the target cell on the preset frequency band is determined, i.e., after the cell on the preset frequency band that meets the camping condition is determined, it is further determined whether the target cell is a cell that can be used by the operator corresponding to the user identification card, i.e., it is determined whether the target cell is the legal cell of the user identification card.

[0041] Exemplarily, taking the first wireless communication module assisting the second wireless communication module in searching for a network as an example. In the related art, after the first wireless communication module searches for a target cell on a preset frequency band, the first wireless communication module directly sends information of the target cell to the second wireless communication module, and the second wireless communication module needs to suspend the network searching and determine whether the target cell sent by the first wireless communication module belongs to a legal cell of the second user identification card; then, when the target cell does not belong to the legal cell of the second user identification card, the second user identification card cannot camp on the target cell, and the second wireless communication module also needs to continue the original network searching, which leads to a decrease in the network searching efficiency of the second wireless communication module. However, in the embodiment provided in the present application, after the first wireless communication module determines the target cell, it is first determined whether the target cell belongs to the legal cell of the second user identification card, and then the information of the target cell is sent to the second wireless communication module after the first wireless communication module determines that the target cell belongs to the legal cell corresponding to the second user identification card, so that the second wireless communication module can directly determine the received target cell as the target cell for camping of the second user identification card, without suspending the network searching process of the second wireless communication module to determine the target cell, thereby improving the network searching efficiency of the second wireless communication module.

[0042] Exemplarily, after searching for the target cell, the first wireless communication module can also determine whether the target cell belongs to the legal cell corresponding to the first user identification card, and if the target cell belongs to the legal cell of the first user identification card, the first wireless communication module controls the first user identification card to camp on the target cell, which will not be described herein.

[0043] In step S103, if the target cell belongs to the legal cell of the second user identification card, a camping instruction is sent to the second wireless communication module to instruct the second user identification card corresponding to the second wireless communication module to camp on the target cell.

[0044] Exemplarily, if the first wireless communication module searches for the target cell belonging to the legal cell of the second user identification card on the preset frequency band, a camping instruction is sent to the second wireless communication module, and the second wireless communication module controls the second user identification card to camp on the target cell according to the camping instruction sent by the first wireless communication module.

[0045] Exemplarily, in this process, the second wireless communication module does not need to suspend the network searching process to determine whether the target cell belongs to the legal cell of the second user identification card, but directly controls the second user identification card to camp on the target cell according to the camping instruction, thereby improving the network searching efficiency of the second wireless communication module.

[0046] For example, if the second user identification card has been previously searched and camped in the cell, the second wireless communication identification module can determine the target cell as a candidate cell of the second user identification card, and determine whether the cell camped by the second user identification card needs to be switched by comparing the signal quality of the candidate cell with the current cell camped by the second user identification card.

[0047] In some embodiments, the camping instruction comprises at least one of the following: public land mobile network information of the target cell, frequency point information of the target cell, and physical cell ID of the target cell.

[0048] For example, the camping instruction comprises cell information used for indicating the target cell, so that the second wireless communication module determines the target cell camped by the second user identification card according to the cell information. The cell information comprises at least one of the following: public land mobile network information of the target cell, frequency point information of the target cell, and physical cell ID of the target cell.

[0049] Please refer to Figure 3 , Figure 3 is a step flowchart of a network searching method of a terminal device provided by an embodiment of the present application.

[0050] As Figure 3 shown, in some embodiments, the network searching method of the terminal device further comprises: if no target cell belonging to a legal cell of the second user identification card is searched in the preset frequency band, sending an ignoring instruction to the second wireless communication module to instruct the second wireless communication module to skip the preset frequency band when searching for a network.

[0051] For example, the case that no target cell belonging to the legal cell of the second user identification card is searched in the preset frequency band comprises any one of the following: no target cell is searched in the preset frequency band; and a target cell is searched in the preset frequency band, but the target cell does not belong to the legal cell of the second user identification card.

[0052] For example, any one of the above two cases indicates that there is no cell in the preset frequency band that can be camped by the second user identification card, i.e., the second wireless communication module does not need to search for a network in the preset frequency band, and the second wireless communication module can skip the preset frequency band when searching for a network according to the instruction of the ignoring instruction.

[0053] For example, after the terminal device is started, each wireless communication module installed on the terminal device starts searching for a network. One user identification card can support multiple frequency bands, and the preset frequency band can also include multiple frequency bands. The wireless communication module that completes the search for the network in the preset frequency band (for example, the search for the network in the preset frequency band can be that a legal cell of another user identification card is found or it is determined that there is no target cell in the preset frequency band) sends the search result in the preset frequency band (for example, target cell information in the preset frequency band or an ignore instruction indicating that there is no target cell in the preset frequency band) to other wireless communication modules, so as to improve the search rate of other wireless communication modules and avoid repeated searches for the network in the same preset frequency band by different wireless communication modules.

[0054] For example, because the searches for the network by the wireless communication modules are performed simultaneously, if the second wireless communication module completes the search for the network in the preset frequency band earlier than the first wireless communication module, the first wireless communication module can also receive the instruction of the second wireless communication module, so as to improve the search efficiency of the first wireless communication module.

[0055] In some embodiments, the search method of the terminal device further includes: controlling the first wireless communication module to skip the frequency band indicated by the received ignore instruction during the search for the network.

[0056] For example, if the second wireless communication module completes the search for the network in the preset frequency band earlier than the first wireless communication module, for example, the second wireless communication module does not search for a legal cell of the first user identification card in a certain frequency band range belonging to the preset frequency band, the second wireless communication module sends an ignore instruction to the first wireless communication module, instructing the first wireless communication module to skip the frequency band range during the search for the network, so as to improve the search frequency of the first wireless communication module.

[0057] In some embodiments, the search method of the terminal device further includes: controlling the first user identification card corresponding to the first wireless communication module to camp on the target cell indicated by the received camp instruction.

[0058] For example, if the second wireless communication module completes the search for the network in the preset frequency band earlier than the first wireless communication module, for example, the second wireless communication module searches for a target cell of a legal cell of the first user identification card in a certain frequency band range belonging to the preset frequency band, the second wireless communication module sends a camp instruction to the first wireless communication module, instructing the first wireless communication module to control the first user identification card to camp on the target cell, so as to improve the search frequency of the first wireless communication module.

[0059] For example, if the first user identification card has previously searched the cell where it is currently residing, the first wireless communication identification module can determine the target cell as a candidate cell for the first user identification card, and determine whether to switch the cell where the first user identification card is currently residing by comparing the signal quality of the candidate cell with the current cell where the first user identification card is currently residing.

[0060] For example, it is assumed that the terminal device includes a first wireless communication module corresponding to a first user identification card, a second wireless communication module corresponding to a second user identification card, and a third wireless communication module corresponding to a third user identification card. The first preset frequency band, the second preset frequency band, and the third preset frequency band are frequency bands supported by the first user identification card, the second user identification card, and the third user identification card. For example, a search method of a terminal device provided by an embodiment of the present application is described based on the first user identification card corresponding to the first wireless communication module: the first wireless communication module is controlled to search for a cell in the first preset frequency band, and if no target cell is found in the first preset frequency band, an ignore instruction is sent to the second wireless communication module and the third wireless communication module. The first wireless communication module is controlled to search for a cell in the second preset frequency band, and if a target cell is found in the second preset frequency band, the target cell in the second preset frequency band belongs to a legal cell of the second user identification card, and a residence instruction is sent to the second wireless communication module, so that the second wireless communication module controls the second user identification card to reside in the target cell. The target cell in the second preset frequency band does not belong to a legal cell of the third user identification card, and an ignore instruction is sent to the third wireless communication module to ignore the second preset frequency band. According to the residence instruction sent by the third wireless communication module, the first wireless communication module controls the first user identification card to reside in the target cell indicated by the residence instruction.

[0061] For example, if no target cell belonging to a legal cell of the first user identification card is found after the first wireless communication module traverses all frequency bands supported by the first user identification card in the current standard, the first wireless communication module can jump to the next standard to search for a cell by using the search method of the terminal device provided by an embodiment of the present application. For example, if no target cell belonging to a legal cell of the first user identification card is found in the 5G standard, the first wireless communication module is controlled to jump to the 4G standard to search for a cell, and of course, the present application is not limited to this, and no limitation is made herein.

[0062] The terminal device searching method provided by the above embodiment determines whether the target cell exists on the preset frequency band by controlling the first wireless communication module to search on the preset frequency band, wherein the preset frequency band belongs to the frequency band corresponding to the first user identification card and belongs to the frequency band corresponding to the second user identification card; if the target cell is searched on the preset frequency band, it is determined whether the target cell belongs to the legal cell of the second user identification card; if the target cell belongs to the legal cell of the second user identification card, a camping instruction is sent to the second wireless communication module to instruct the second user identification card corresponding to the second wireless communication module to camp on the target cell. By sharing the target cell belonging to the legal cell between the user identification cards, the second user identification card can directly determine the camping target cell according to the searching result of the first wireless communication module, and the first wireless communication module and the second wireless communication module do not need to search on the same preset frequency band, thereby reducing the repeated searching on the same frequency band and improving the searching efficiency.
