Description

Technical Field

[0001] This application relates to communication technology, and more particularly to a network searching method, apparatus, chip, and storage medium. Background Technology

[0002] In a dual-SIM terminal, if only the Subscriber Identity Module (SIM) card is inserted into the first SIM slot, all communication occurs only in the protocol stack of the first SIM slot; the protocol stack of the second SIM slot remains inactive. Thus, when the terminal needs to re-search for a network, the protocol stack of the first SIM slot first scans previously used frequency bands. If a valid network is found in a historical frequency band and registration is successful, the terminal camps on a cell normally. If no successful camping occurs in any historical frequency band, the terminal then performs a full-band search based on its supported frequency bands until a valid network is found and a suitable cell is located. This current network search method is time-consuming. Summary of the Invention

[0003] This application aims to provide a method, apparatus, chip, and storage medium for searching the web.

[0006] When a SIM card is inserted into the first card slot, and the terminal is determined to meet the preset network search conditions, a list of frequency points to be scanned is obtained.

[0008] The first protocol stack performs a cell search on the first frequency list, and the second protocol stack performs a cell search on the second frequency list to determine the first serving cell that meets the camping conditions.

[0009] Residing in the first service area.

[0010] Secondly, a network search device is provided, applied to a terminal, the terminal including a first SIM card slot and a second SIM card slot, the protocol stack of the first SIM card slot being a first protocol stack, and the protocol stack of the second SIM card slot being a second protocol stack; the device includes:

[0024] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0025] This application provides a method for searching a network. Figure 1 This is a flowchart illustrating the network searching method in the embodiments of this application. Figure 1 This is applied to a terminal, which includes a first SIM card slot and a second SIM card slot. The protocol stack of the first SIM card slot is a first protocol stack, and the protocol stack of the second SIM card slot is a second protocol stack. For example, the terminal can be a mobile phone, a smartwatch, etc.

[0026] like Figure 1 As shown, this web search method may specifically include:

[0027] Step 101: With a SIM card inserted in the first card slot, and the terminal meeting the preset network search conditions, obtain the list of frequency points to be scanned.

[0028] In practical applications, receiving a voltage signal from the card slot module indicates that a SIM card is inserted in the corresponding slot. Here, the terminal only receives the voltage signal from the first card slot, therefore it assumes that only the first card slot has a SIM card inserted.

[0029] In some embodiments, the preset network search conditions include: the terminal switching from a powered-off state to a powered-on state. That is, when the terminal is first powered on, it needs to search for a network.

[0030] In some embodiments, the preset network search conditions include: after the terminal camps on the second serving cell, a no-service phenomenon is detected in the terminal.

[0031] If the terminal is currently normally camped on the second serving cell, and the signal coverage is poor or the terminal is roaming to another country resulting in no service, it means that the terminal needs to search for a network again.

[0032] Here, obtaining the list of frequency points to be scanned is for performing a cell search on the list of frequency points to be scanned, so as to find the cells where the terminal can camp.

[0033] Step 102: Allocate a first frequency point list to the first protocol stack and a second frequency point list to the second protocol stack according to the frequency point list to be scanned.

[0034] This application assigns the list of frequency points to be scanned to a first protocol stack with an inserted SIM card and a second protocol stack without an inserted SIM card. The purpose is to leverage the second protocol stack without an inserted SIM card to share some of the communication capabilities of the first protocol stack with an inserted SIM card, thereby enabling dual-protocol-stack collaborative network search and improving network search speed.

[0035] In some embodiments, step 102 specifically includes: dividing the list of frequency points to be scanned into a first frequency point list and a second frequency point list by staggering the frequency point order.

[0036] The list of frequencies to be scanned will be evenly divided into a first frequency list and a second frequency list.

[0037] Step 103: Perform cell search on the first frequency list through the first protocol stack, and perform cell search on the second frequency list through the second protocol stack to determine the first serving cell that meets the camping conditions.

[0038] In some embodiments, step 103 specifically includes: performing a cell search on the first frequency point list using the first protocol stack to obtain the cell with the highest reference signal received power at each frequency point in the first frequency point list; performing a cell search on the second frequency point list using the second protocol stack to obtain the cell with the highest reference signal received power at each frequency point in the second frequency point list; determining the target cell with the highest reference signal received power based on the cells with the highest reference signal received power at each frequency point in the first frequency point list and the cells with the highest reference signal received power at each frequency point in the second frequency point list; and when the target cell meets the camping conditions, using the target cell as the first serving cell.

[0039] In other words, cell search is performed on the first frequency list through the first protocol stack, and cell search is performed on the second frequency list through the second protocol stack. After the cell search is completed, the cells with the highest Reference Signal Receiving Power (RSRP) at each frequency point in the first and second frequency lists (i.e., all frequency points) are aggregated. Then, the target cell with the highest RSRP is found from the cells with the highest RSRP at each frequency point in all frequency points. Then, it is determined whether the target cell meets the camping conditions. If it does, the target cell is the cell where the terminal can camp, i.e., the first serving cell.

[0040] In some embodiments, step 103 specifically includes: performing cell search on the first frequency list through the first protocol stack, and performing cell search on the second frequency list through the second protocol stack. If the cell with the highest reference signal received power under the target frequency meets the camping condition, then the target cell under the target frequency is taken as the first serving cell; wherein, the target frequency is a frequency in the first frequency list or a frequency in the second frequency list.

[0041] In other words, a cell search is performed on the first frequency list through the first protocol stack, and a cell search is performed on the second frequency list through the second protocol stack. During the cell search, if one of them (the first protocol stack with a SIM card inserted or the second protocol stack without a SIM card inserted) finds a cell that can be camped first, then the search result is reported and the cell is camped.

[0042] In some embodiments, the method further includes:

[0043] Obtain the reference signal reception quality of the target cell;

[0044] The received signal quality is determined based on the reference signal reception quality of the target cell;

[0045] The received signal level is determined based on the reference signal received power of the target cell;

[0046] The dwell conditions include: the received signal quality of the target cell is greater than zero, and the received signal level of the target cell is greater than zero.

[0047] In other words, when the received signal quality of the target cell is greater than zero and the received signal level of the target cell is greater than zero, it means that the target cell meets the camping conditions, and the terminal can camp on the target cell. The received signal quality is determined by the Reference Signal Receiving Quality (RSRQ), and the received signal level is determined by the Reference Signal Receiving Power (RSRP).

[0048] Step 104: Stay in the first service area.

[0049] Here, the execution entity for steps 101 to 104 can be the terminal's processor.

[0050] It should be noted that after the above steps are completed, the terminal successfully camps on the first serving cell. If it is doing other things through the first protocol stack, it can use the second protocol stack to receive data sent to the first protocol stack by the network device (such as parsing system messages). This allows the second protocol stack without a SIM card to share some of the communication capacity of the first protocol stack with a SIM card, thereby improving the data processing speed.

[0051] By adopting the above technical solution, this application allocates the list of frequency points to be scanned to the first protocol stack with the SIM card inserted and the second protocol stack without the SIM card inserted. The purpose is to use the second protocol stack without the SIM card inserted to share part of the communication capacity of the first protocol stack with the SIM card inserted, and to perform dual protocol stack collaborative network search, thereby improving the network search speed.

[0052] To better illustrate the purpose of this application, further examples are provided based on the above embodiments. Figure 2 This is a flowchart illustrating the network searching method in the embodiments of this application. Figure 2 ,like Figure 2 As shown, this web search method specifically includes:

[0053] Step 201: With the SIM card inserted in the first card slot, and the terminal meeting the preset network search conditions, obtain the historical network standard list of the SIM card.

[0054] In practical applications, receiving a voltage signal from the card slot module indicates that a SIM card is inserted in the corresponding slot. Here, the terminal only receives the voltage signal from the first card slot, therefore it assumes that only the first card slot has a SIM card inserted.

[0055] In some embodiments, the preset network search conditions include: the terminal switching from a powered-off state to a powered-on state. That is, when the terminal is first powered on, it needs to search for a network.

[0056] In some embodiments, the preset network search conditions include: after the terminal camps on the second serving cell, a no-service phenomenon is detected in the terminal.

[0057] If the terminal is currently normally camped on the second serving cell, and the signal coverage is poor or the terminal is roaming to another country resulting in no service, it means that the terminal needs to search for a network again.

[0058] Here, the list of historical network standards includes at least New Radio (NR), i.e. 5G, and Long Term Evolution (LTE), i.e. 4G.

[0059] Step 202: Obtain the target network standard from the historical network standard list according to the network standard order from high to low.

[0060] Based on the order of network standards from highest to lowest, the historical network standard list is sorted as 5G, then 4G. Therefore, 5G network standards are given priority here.

[0061] Step 203: Determine the list of frequency points to be scanned based on the target network standard and the terminal's frequency scanning method.

[0062] The terminal's frequency scanning methods include system scan and full-band scan.

[0063] In some embodiments, step 203 specifically includes: when it is determined that the frequency scanning method of the terminal is system frequency scanning, obtaining a list of target frequency points where the SIM card has historically resided under the target network standard;

[0064] The list of frequency points to be scanned is obtained from the target frequency point list.

[0065] When the terminal uses system frequency scanning, it obtains the list of target frequency points that the SIM card has historically resided in under the target network standard. This list of target frequency points is the list of frequency points to be scanned.

[0066] In some embodiments, step 203 specifically includes: when it is determined that the frequency scanning method of the terminal is full-band frequency scanning, obtaining the frequency bands supported by the SIM card under the target network standard;

[0067] The list of frequency points to be scanned is obtained based on the frequency band.

[0068] For example, sorting multiple frequency points in a frequency band from low to high or from high to low will yield a list of frequency points to be scanned.

[0069] Step 204: Allocate a first frequency point list to the first protocol stack and a second frequency point list to the second protocol stack according to the frequency point list to be scanned.

[0070] For example, Table 1 is a list of historical target frequency points (i.e., frequency points to be scanned) obtained under the system frequency scanning method. It includes at least frequency point 1, frequency point 2, frequency point 3, frequency point 4, frequency point 5, frequency point 6, frequency point 7 and frequency point 8. The frequency points are staggered and evenly distributed to the first protocol stack (represented by S1 in the table below) and the second protocol stack (represented by S2 in the table below) according to the order of this list. That is, frequency points 1, frequency points 3, frequency points 5 and frequency points 7 are assigned to the first protocol stack, and frequency points 2, frequency points 4, frequency points 6 and frequency points 8 are assigned to the second protocol stack.

[0071]

[0072] The list of target frequencies for historical residency can be sorted by time or size. Table 1 shows one example of allocation; other allocation methods are also acceptable as long as they are evenly distributed, and are not limited here.

[0073] For example, Table 2 shows the frequency bands supported by the SIM card (i.e., the list of frequency points to be scanned) obtained under the full-band frequency scanning method, including at least frequency points 11, 22, 33, 44, 55, 66, 77, and 88. These frequency bands are divided into two segments and assigned to the first protocol stack (represented by S1 in the table below) and the second protocol stack (represented by S2 in the table below). Specifically, the frequency bands can be divided into two segments staggered from low to high or from high to low. That is, frequency points 11, 33, 55, and 77 are assigned to the first protocol stack, and frequency points 22, 44, 66, and 88 are assigned to the second protocol stack.

[0074]

[0075]

[0076] Table 2 shows one example of allocation. Other allocation methods are also possible, as long as the distribution is equal. No restrictions are imposed here.

[0077] Step 205: Perform cell search on the first frequency list through the first protocol stack, and perform cell search on the second frequency list through the second protocol stack to determine the first serving cell that meets the camping conditions.

[0078] Step 206: Stay in the first service area.

[0079] In some embodiments, the method further includes: if no first serving cell that meets the dwell conditions is determined, continuing the network search process based on the next network standard in the historical network standard list.

[0080] If no first service area that meets the residency criteria is identified, continue with steps 202 to 205.

[0081] Using the above technical solution, this application specifically determines the list of frequency points to be scanned based on the target network standard and the frequency scanning method of the terminal, and then assigns the list of frequency points to be scanned to the first protocol stack with the SIM card inserted and the second protocol stack without the SIM card inserted. This is to use the second protocol stack without the SIM card inserted to share part of the communication capacity of the first protocol stack with the SIM card inserted, and to perform dual protocol stack collaborative network search, thereby improving the network search speed.

[0082] Based on the above embodiments, this application exemplifies a method for searching a network. Figure 3 This is a flowchart illustrating the network searching method in the embodiments of this application. Figure 3 ,like Figure 3 As shown, this web search method specifically includes:

[0083] Step 301: Supports the case where a SIM card is inserted into the first card slot of a dual-SIM terminal.

[0084] In practical applications, receiving a voltage signal from the card slot module indicates that a SIM card is inserted in the corresponding slot. Here, the terminal only receives the voltage signal from the first card slot, therefore it assumes that only the first card slot has a SIM card inserted.

[0085] Step 302: The terminal resides in the second serving cell.

[0086] Step 303: A no-service status was detected on the terminal.

[0087] For example, the terminal may experience a lack of service due to poor signal coverage in its location or roaming to other countries.

[0088] Step 304: Obtain the historical network standard list of the SIM card.

[0089] The list of historical network standards includes at least 5G and 4G.

[0090] Step 305: Determine whether to perform a system frequency sweep or a full-band frequency sweep; if a system frequency sweep is to be performed, proceed to step 306; if a full-band frequency sweep is to be performed, proceed to step 307.

[0091] Step 306: Obtain the list of target frequency points where the SIM card has historically camped under the target network standard, and assign them to the first protocol stack and the second protocol stack.

[0092] The historical network standard list includes at least 5G and 4G, and the target network standard is the highest network standard in the historical network standard list, namely 5G.

[0093] Step 307: Obtain the frequency bands supported by the SIM card under the target network standard and allocate them to the first protocol stack and the second protocol stack.

[0094] Step 308: Perform cell search simultaneously using the first protocol stack and the second protocol stack.

[0095] Step 309: Has a suitable community been found? If yes, proceed to step 310; if no, proceed to step 311.

[0096] Step 310: Report the search results.

[0097] This means residing in the new service cell, i.e., the first service cell, to restore communication services.

[0098] Step 311: Obtain the next network standard from the historical network standard list.

[0099] When executing step 311, if no serving cell that meets the camping conditions is found, the network search process continues based on the next network standard until a cell that the terminal can camp on is found.

[0100] To implement the method of the embodiments of this application, based on the same inventive concept, a network searching device is also provided in the embodiments of this application. Figure 4 This is a schematic diagram of the network search device structure in an embodiment of this application. The terminal includes a first card slot and a second card slot. The protocol stack of the first card slot is a first protocol stack, and the protocol stack of the second card slot is a second protocol stack. Figure 4 As shown, the search device 40 specifically includes:

[0104] By adopting the above technical solution, this application allocates the list of frequency points to be scanned to the first protocol stack with the SIM card inserted and the second protocol stack without the SIM card inserted. The purpose is to use the second protocol stack without the SIM card inserted to share part of the communication capacity of the first protocol stack with the SIM card inserted, and to perform dual protocol stack collaborative network search, thereby improving the network search speed.

[0114] Based on the cell with the highest reference signal received power at each frequency point in the first frequency point list and the cell with the highest reference signal received power at each frequency point in the second frequency point list, determine the target cell with the highest reference signal received power.

[0115] When the target cell meets the dwell conditions, the target cell is designated as the first serving cell.

[0116] In some embodiments, the execution unit 403 is specifically used to perform cell search on the first frequency list through the first protocol stack, and during the process of performing cell search on the second frequency list through the second protocol stack, if the cell with the highest reference signal received power under the target frequency meets the camping condition, then the target cell under the target frequency is taken as the first serving cell.

[0117] The target frequency point is either a frequency point in the first frequency point list or a frequency point in the second frequency point list.
