Among them, the 5G mobile communication system may include non-standalone networking (Non-Standalone, NSA) and / or standalone networking (Standalone, SA).

[0062] Before introducing the technical solution of this application, some background technical knowledge involved in this application is first introduced and explained. The following related technologies can be combined arbitrarily with the technical solution of the embodiment of this application as optional solutions, and they all belong to the protection scope of the embodiment of this application. The embodiment of this application includes at least part of the following contents:

[0063] When the terminal device is in a high-speed mobile state (such as when the user is riding a high-speed train), the speed of change of the wireless environment will increase significantly, which makes the traditional radio resource control (RRC) reconstruction mechanism face challenges. Specifically, when the RRC connection reconstruction fails, the terminal device needs to re-search for available networks according to the preset algorithm, which may involve scanning multiple frequency points and multiple cells.

[0064] However, in the above scheme, comprehensive network search is not only time-consuming, but also the searched network may quickly become unavailable due to the rapidly changing environment, further affecting the user experience. Specifically, in high-speed mobile scenarios, terminal devices may need to scan multiple frequency bands to find a suitable cell for reconnection, which is a time-consuming process, especially at the edge of network coverage or in areas with weak signals. In addition, due to the rapid changes in the network environment, even if the terminal device finds an accessible cell, the connection may be interrupted again due to moving to another area, which leads to unnecessary resource consumption and decreased user perception. Therefore, long network recovery time and frequent disconnection seriously affect the user's communication experience, especially when conducting real-time applications such as voice calls or video streaming.

[0065] In this regard, the subsequent embodiments of the present application provide a new network search solution, which can reduce the time of RRC reconstruction, improve the stability and efficiency of network connection in complex mobile environments, and ultimately improve the user experience.

[0066] Please refer to Figure 2 , which shows a flow chart of a network search method provided by an exemplary embodiment of the present application. The method can be used in a terminal device; for example, the terminal device can be the above-mentioned Figure 1 The terminal device 120 in the system shown; alternatively, the terminal device may also be Figure 1 Other terminal devices outside the system shown. The method may include the following steps.

[0067] Step 210: Obtain device information of the terminal device, where the device information includes geographic location information.

[0068] The terminal device may obtain the current location information of the terminal device through positioning technology (such as satellite positioning technology) as the above-mentioned geographical location information.

[0069] Optionally, the above device information may also include signal strength, network operator, etc.

[0070] Step 220: query the recommended frequency list according to the device information of the terminal device to obtain a first frequency list.

[0071] The recommended frequency list may be pre-set / configured in the terminal device. For example, the recommended frequency list may be constructed based on historical frequency data and geographic location information accessed by the terminal device.

[0072] Exemplarily, the above-mentioned recommended frequency point list may include a set of various frequency points related to different device information of the terminal device.

[0073] The order of the frequencies in the recommended frequency list may be related to the access success rate. For example, the higher the access success rate, the higher the position of the frequency in the recommended frequency list. For another example, when the access success rate of a candidate frequency satisfies a specified range, the candidate frequency is added to the recommended frequency list.

[0074] Step 230: Perform a network search operation according to the arrangement order of the frequencies in the first frequency list.

[0075] Optionally, the terminal device can search for multiple frequencies in the first frequency list at the same time to facilitate quick access.

[0076] To summarize, through the scheme shown in the embodiment of the present application, the terminal device can query the recommended frequency list based on the device information including the current geographic location, obtain the frequency list related to the current device information of the terminal device, and then perform the network search operation in sequence according to the frequencies in the queried frequency list, so as to quickly restore the network service of the terminal device when the network connection is abnormal, improve the network search efficiency, and thereby improve the stability of the network connection.

[0077] Based on the above Figure 2 In the solution shown, in a possible implementation manner, the terminal device stores a correspondence between the frequency point list and the path area.

[0078] That is to say, terminal devices in different path areas may correspond to different frequency lists. Exemplarily, a mapping table between frequency lists and path areas may be stored in the terminal device. For example, the corresponding relationship between frequency lists and path areas is shown in Table 1.

[0079] Table 1

[0080] Frequency list Frequency list 1 Frequency list 2 Frequency list 2 Frequency list 3 …… Path area Path Area 1 Path Area 2 Path Area 3 Path Area 4 ……

[0081] The above-mentioned path area may be a traffic route frequently traveled by the user of the terminal device, including expressways, railways, urban trunk roads, tunnels, and the like.

[0082] Please refer to Figure 3 , which shows a flow chart of a network search method provided by an exemplary embodiment of the present application. The above step 220 can be implemented as step 220a and step 220b.

[0083] Step 220a: Determine the path area where the terminal device is located according to the geographical location information of the terminal device.

[0084] In an embodiment of the present application, the terminal device can obtain a path area containing the geographical location information from multiple path areas based on the current geographical location information.

[0085] Step 220b: query the frequency point list corresponding to the path area where the terminal device is located from the corresponding relationship as the first frequency point list.

[0086] The terminal device may obtain, according to the path area determined in step 220a, a first frequency point list corresponding to the path area from the correspondence between the frequency point list and the path area.

[0087] The embodiment of the present application provides a feasible solution related to the frequency list and the path area. The manufacturer / service provider of the terminal device can build a frequency list corresponding to the path area according to the path area with high user travel frequency; thereafter, the terminal device can determine the path area according to the geographical location information of the terminal device, and then determine the first frequency list corresponding to the path area; thereby improving the success rate of performing network search through the first frequency list.

[0088] Based on the above Figure 3 In the solution shown, in a possible implementation, the device information also includes operator information; the above step 220b can be implemented as follows:

[0089] A frequency list corresponding to the path area where the terminal device is located and the operator information is queried from the corresponding relationship as the first frequency list.

[0090] The above-mentioned operator information may be the information of the network service provider corresponding to the network card of the terminal device.

[0091] A terminal device can correspond to one or more operator information. For different path areas, the frequency points corresponding to different operators may be different.

[0092] For example, the terminal device may pre-store a list of path areas and frequencies corresponding to each operator. For example, please refer to Table 2 below.

[0093] Table 2

[0094]

[0095]

[0096] In an embodiment of the present application, the above-mentioned first frequency point list is not only related to the path area where the terminal device is located, but also related to the operator information of the terminal device, which can further optimize the accuracy and access success rate of the first frequency point list.

[0097] Based on the solutions shown in the above embodiments, in a possible implementation manner, the device information also includes moving speed information;

[0098] The above step 220a may be implemented as follows:

[0099] When the moving speed indicated by the moving speed information is in the first speed interval, the path area where the terminal device is located is determined according to the geographical location information of the terminal device.

[0100] The above-mentioned moving speed information may be the moving speed of the means of transportation that the user carries the terminal device on. Different means of transportation correspond to different moving speeds. Exemplarily, the above-mentioned means of transportation may include one or more of high-speed rail, subway, bus, taxi, online car-hailing, and private car.

[0101] Exemplarily, the terminal device may obtain continuous geographical location information of the terminal device through positioning technology (such as satellite positioning technology), and then calculate the moving speed of the terminal device.

[0102] The first speed range may be pre-set / configured in the terminal device. For example, the first speed range is above 200 km / h; or, for another example, the first speed range is between 300 km / h and 500 km / h.

[0103] In an embodiment of the present application, the terminal device can obtain the moving speed of the terminal device. If the current moving speed of the terminal device is in the first speed range, the terminal device can determine the type of transportation used by the user to carry the terminal device. Combined with the geographic location information, the path area where the terminal device is located can be determined, thereby improving the accuracy of determining the path area.

[0104] For example, if the mobile speed of the terminal device is in the first speed range above 200 km / h, it can be inferred that the means of transportation that the user carries the terminal device on is a high-speed rail, that is, the terminal device is in a high-speed moving state, and RRC reconstruction failure may occur subsequently, resulting in re-searching the network. At this time, the path area where the terminal device is located can be determined based on the geographical location information of the terminal device, so as to determine the first frequency point list for searching the network.

[0105] Based on the solutions shown in the above embodiments, in a possible implementation manner, the device information also includes moving speed information;

[0106] The above step 220b can be implemented as follows:

[0107] In the case where the moving speed information matches the path area where the terminal device is located, a frequency point list corresponding to the path area where the terminal device is located is queried from the corresponding relationship as the first frequency point list.

[0108] Among them, when the terminal device is in a certain path area, the speed range corresponding to the mobile speed of the terminal device matches the path area. For example, when a user takes a high-speed train with a terminal device, the mobile speed of the terminal device is usually above 200km / h.

[0109] In addition, in real life, the driving areas of different vehicles are intersecting, but the driving speeds of different vehicles are different and vary greatly. Therefore, in order to avoid errors in determining the path area where the terminal device is located, the embodiment of the present application can combine the moving speed information of the terminal device to determine whether the path area where the terminal device is located is accurate.

[0110] For example, the terminal device may pre-store the moving speed intervals corresponding to each path area. For example, please refer to the following Table 3.

[0111] Table 3

[0112] Path area Movement speed range Path Area 1 120km / h-180km / h Path Area 2 160km / h-250km / h Path Area 3 220km / h-350km / h …… ……

[0113] In an embodiment of the present application, when the moving speed information of the terminal device matches the path area determined above, the terminal device queries the first frequency point list corresponding to the path area where the terminal device is located from the corresponding relationship, which can improve the accuracy of determining the first frequency point list.

[0114] Based on the solutions shown in the above embodiments, in a possible implementation manner, the above network search method further includes:

[0115] When the moving direction indicated by the moving speed information is the same as or opposite to the specified direction, and the moving speed indicated by the moving speed information is in the second speed interval, determining that the moving speed information matches the path area where the terminal device is located;

[0116] The specified direction is the extension direction of the path area where the terminal device is located at the position corresponding to the geographical location information; the second speed interval is the moving speed interval of the vehicle on the path area where the terminal device is located.

[0117] The above-mentioned moving speed information may also indicate the moving direction of the terminal device.

[0118] The terminal device may obtain the path area data, which includes the shape, direction and attributes of the road. For example, the terminal device may extract the path area data at the geographical location from the path area data according to the current geographical location of the terminal device; then, extract the road direction at the geographical location from the path area data, and compare whether the road direction at the geographical location is the same as or opposite to the moving direction indicated by the moving speed information.

[0119] In the embodiment of the present application, in order to ensure that the terminal device can accurately match the path area where it is located, it is necessary to comprehensively consider multiple factors, including moving speed information, moving direction and characteristics of the path area. This solution uses the moving direction of the terminal device as a condition for matching the path area, which can ensure the accuracy and reliability of the matching.

[0120] Based on the solutions shown in the above embodiments, in a possible implementation manner, the above step 230 can be implemented as follows:

[0121] When a wireless link failure occurs in the terminal device and the radio resource control RRC reconstruction fails, a network search operation is performed according to the arrangement order of the frequencies in the first frequency list.

[0122] The above-mentioned wireless link failure refers to the situation where the wireless link between the terminal device and the cell is interrupted. For example, when the terminal device is far away from the network device or located at the edge of the cell, the wireless link failure occurs; for example, when the terminal device fails to switch from one cell to another, the wireless link failure may also occur.

[0123] The above-mentioned RRC reestablishment failure refers to the failure of the terminal device to reestablish the RRC connection. The RRC reestablishment failure means that the terminal device fails to successfully restore the connection with the network device, resulting in a service interruption of the terminal device, such as call interruption, data service unavailability, etc.

[0124] The embodiment of the present application provides a prerequisite for performing a network search operation in the order of arrangement of the frequencies in the first frequency list, which is a wireless link failure and a wireless resource control RRC reconstruction failure. This can limit the application scenario of the present solution and improve the accuracy of the application of the present solution.

[0125] Based on the solutions shown in the above embodiments, in a possible implementation manner, the above step 220 can be implemented as follows:

[0126] Obtain the horizontal movement speed change information of the terminal device within a specified time period before the current time;

[0127] When the mobile speed change information meets the specified conditions, the recommended frequency list is queried according to the device information of the terminal device to obtain the first frequency list.

[0128] The above-mentioned specified conditions may be conditions pre-set / configured in the terminal device and used to determine whether the path area where the terminal device is located has changed.

[0129] In the embodiment of the present application, the terminal device can infer the behavior of the user carrying the terminal device based on the mobile speed change information of the terminal device, and then determine whether the path area where the terminal device is located has changed. For example, within 5 minutes, the mobile speed of the terminal device increases from about 4km / h to more than 200km / h. At this time, it can be inferred that the user carrying the terminal device may be riding a high-speed train; accordingly, the terminal device can query the first frequency point list so as to perform a network search operation through the first frequency point list later.

[0130] Through the scheme shown in the above embodiments of the present application, the terminal device can dynamically adjust the frequency selection strategy according to the mobile speed change information, so that the terminal device can promptly determine the frequency list used for network search, thereby improving the stability of the network connection.

[0131] Based on the solutions shown in the above embodiments, in a possible implementation manner, the specified condition includes at least one of the following:

[0132] The moving speed change value indicated by the moving speed change information is greater than the change value threshold;

[0133] The moving speed change rate indicated by the moving speed change information is greater than the change rate threshold.

[0134] Among them, the above-mentioned change value threshold and the above-mentioned change rate threshold can be pre-set / configured in the terminal device.

[0135] The above-mentioned moving speed change value may be the difference between the first moving speed corresponding to the start time of the specified time before the current time and the second moving speed corresponding to the current time. The above-mentioned moving speed change rate may be the degree of change of the second moving speed compared with the first moving speed.

[0136] The embodiments of the present application provide a variety of combinations of the above-mentioned specified conditions, which may include but are not limited to: one or a combination of a mobile speed change value greater than a change value threshold, a mobile speed change rate greater than a change rate threshold, and may also include other information. The embodiments of the present application do not limit this, thereby improving the flexibility of obtaining the first frequency point list.

[0137] Based on the solutions shown in the above embodiments, in a possible implementation manner, the above step 220 can be implemented as follows:

[0138] When the duration between the current time and the time when the recommended frequency list was last queried is not less than the duration threshold, the recommended frequency list is queried according to the device information of the terminal device to obtain a first frequency list.

[0139] That is, the terminal device may record the time at which the recommended frequency list is queried each time, so as to quickly obtain the duration between the current time and the time at which the recommended frequency list was queried last time.

[0140] The duration threshold may be pre-set / configured in the terminal device. For example, the duration threshold may be 5 minutes; or other thresholds may be used, which are not limited in the present application.

[0141] Optionally, the duration thresholds corresponding to different situations may be the same or different.

[0142] The embodiment of the present application provides the frequency of the terminal device querying the recommended frequency list, and controls the frequency of the terminal device querying the recommended frequency list within a reasonable range, which can improve the timeliness of obtaining / updating the first frequency list, thereby improving the stability of the network connection.

[0143] Based on the solutions shown in the above embodiments, in a possible implementation manner, the duration threshold is associated with a second frequency point list, and the second frequency point list is a recommended frequency point list queried last time.

[0144] That is to say, the duration thresholds corresponding to different moments may be different.

[0145] In an embodiment of the present application, the above-mentioned duration threshold is associated with the recommended frequency list queried last time. For example, for the path areas corresponding to different recommended frequency lists, the above-mentioned duration threshold is different. For example, when the path area corresponding to the recommended frequency list is the path area of ​​the high-speed rail, the above-mentioned duration threshold can be 5 minutes; when the path area corresponding to the recommended frequency list is the path area of ​​the subway, the above-mentioned duration threshold can be 1 minute.

[0146] For example, the terminal device may pre-store the duration thresholds corresponding to each second frequency point list, for example, please refer to Table 4 below.

[0147] Table 4

[0148] Second frequency list Duration Threshold Second frequency list 1 5 minutes Second frequency list 2 1 minute Second frequency list 3 10 minutes …… ……

[0149] Based on the solutions shown in the above embodiments, in a possible implementation, the duration threshold is associated with a moving speed interval of a vehicle on a path area corresponding to the second frequency point list; or,

[0150] The duration threshold is associated with the type of transportation in the path area corresponding to the second frequency point list; or,

[0151] The duration threshold is associated with the type of the path area corresponding to the second frequency point list.

[0152] Among them, different path areas correspond to different means of transportation, and different path areas correspond to different moving speed ranges of the means of transportation.

[0153] Optionally, the above-mentioned duration threshold may be positively correlated with the moving speed interval of the vehicle in the path area corresponding to the second frequency point list.

[0154] The embodiments of the present application provide multiple implementable methods for associating the duration threshold with the second frequency point list, which can improve the flexibility of the solution.

[0155] The solutions shown in the above embodiments can be applied to travel scenarios on fixed routes, for example, scenarios where users commute by public transportation (such as high-speed rail, subway, bus, taxi, online car-hailing, private car).

[0156] In the above scenario, the frequency band information of the line can be collected in advance. For example, taking the high-speed rail line between high-speed rail station 1 and high-speed rail station 2 as an example, the main frequency point information of the network deployed on the high-speed rail line can be collected; according to the Internet experience and switching smoothness, the above frequency point information is sorted, and the frequency point information with a higher access success rate is ranked first. Afterwards, a specific network model can be established based on the line, and the frequency points with a high access success rate on a specific line can be selected, and other frequencies that are not deployed and have a low access success rate can be eliminated. Afterwards, the frequency point information collected in the early stage can be made into a frequency point list corresponding to the line, as a pre-stored frequency point (Stored arfcn), and stored in the terminal device.

[0157] In actual use, when a user enters a certain line, the stored arfcn of the line is dynamically loaded. When RLF occurs on the line and RRC reconstruction fails, the stored arfcn is used first to search the network, and then access is made after a specific cell is found, thus speeding up network recovery.

[0158] For example, if the terminal device is a mobile phone, please refer to Figure 4 , which shows a schematic diagram of the establishment and application of a frequency point list provided by an exemplary embodiment of the present application.

[0159] In the frequency list establishment phase, the mobile phone manufacturer / service provider can measure each line in advance to obtain the frequency list, store it in the server, and push it to the mobile phone. Figure 4As shown in part (a) of FIG. 1 , the measurement personnel 10 performs measurement on line 1, collects frequency information of each frequency point, and sorts the frequency information of each frequency point according to the access success rate to obtain the frequency list 01 of line 1; similarly, the measurement personnel 10 can obtain the frequency list 02 of line 2, the frequency list 03 of line 3, and the frequency lists of other lines. Afterwards, the measurement personnel 10 can upload the frequency list 01 of line 1, the frequency list 02 of line 2, the frequency list 03 of line 3, and the frequency lists of other lines to the server 101; accordingly, the server 101 can push the frequency list of each line to the mobile phone 102 located on the corresponding line.

[0160] In the application stage of the frequency list, the mobile phone can determine the route according to the location, query the corresponding frequency list, and perform network search according to the frequency list. Figure 4 As shown in part (b) of FIG. 1 , user 20 carries mobile phone 201 and is located at line 1 . Mobile phone 1 can query frequency list 02 corresponding to line 1 , and perform a network search operation according to the arrangement order of the frequencies in frequency list 02 .

[0161] Specifically, please refer to Figure 5 , which shows a flow chart of a method for applying a frequency point list provided by an exemplary embodiment of the present application. Figure 5 As shown, the above network card switching method includes the following steps:

[0162] S1, determine the line:

[0163] Among them, the mobile phone can obtain its own geographical location through positioning technology;

[0164] Afterwards, based on the geographical location, the mobile phone can determine the route it is on from multiple routes (i.e., the above-mentioned traffic routes);

[0165] S2, check whether there is a frequency list matching the line:

[0166] The mobile phone can query whether there is a frequency point list matching the line from the corresponding relationship between the frequency point list and the line (such as the above Table 1);

[0167] If there is a frequency point list matching the line, go to step S3;

[0168] Otherwise, return to step S1;

[0169] S3, determine whether the phone is RLF and RRC reestablishment fails:

[0170] If the mobile phone has RLF and RRC reestablishment fails, go to step S4;

[0171] Otherwise, loop step S3;

[0172] S4, perform network search operation:

[0173] The mobile phone may perform a network search operation according to the arrangement order of the frequencies in the frequency list.

[0174] In summary, this application can extract specific frequency information based on historical information collected from surveys of specific high-speed rail / subway lines, and pre-store these frequency points; after identifying that the user's terminal device is on the specified line, the Stored arfcn can be used to restore the network connection as soon as possible after RLF.
