The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It is understandable that the specific embodiments described here are only used to explain the related application, but not to limit the application. In addition, it should be noted that, for ease of description, only the parts related to the relevant application are shown in the drawings.

With the development of mobile communication technology, multi-mode terminal technology has been very mature and has been well commercialized. A multi-mode terminal mainly refers to a device that can support multiple access technologies at the same time. It can be a dual-mode terminal, a three-mode terminal, a four-mode terminal, or even a multi-mode terminal. Among them, wireless access technology (also called air interface) refers to connecting user terminals and network nodes through wireless media to realize information transfer between users and the network. Here, the wireless access technology can include multiple access technologies such as GSM, UMTS, LTE, and NR. For each access technology, it can also include multiple frequency bands; for example, for GSM, it can include GSM- Multiple frequency bands such as 850/GSM-900/GSM-1800/GSM-1900; for UMTS, multiple frequency bands such as 2100/1900/1800/1700/850 may be included, which is not limited in the embodiment of this application.

In practical applications, after a multi-mode terminal is turned on, it usually needs to search the network. The current network search process is usually to try the network search operation for the network standard information (including all wireless access technologies and frequency bands) supported by the multi-mode terminal. Specifically, as shown in FIG. 1, it shows a schematic structural diagram of a typical network search working mode provided by related technical solutions. In Figure 1, radio access technologies can include four types of NR/LTE/UMTS/GSM, among which GSM can also be called 2G access technology, and UMTS can also be called 3G access technology. Each type of access The technology can include multiple frequency bands. Taking the NR technology as an example, it is assumed that four frequency bands such as a/b/x/y can be included. It can be seen from Figure 1 that for multi-mode terminals, the network search mode is to repeat the network search at a certain time interval (Timeout, T), and in each search cycle, it will search for the supported All wireless access technologies and frequency bands; but this will bring challenges to network search and selection, which not only brings power consumption issues, but also brings a delay in network search time.

Considering the continuous evolution of network technology, as shown in FIG. 2, it shows a schematic diagram of a mobile subscription report classified by region and technology provided by related technical solutions. Among them, the wireless access technology covers 5G, LTE (4G), Wideband Code Division Multiple Access (WCDMA)/High-Speed Packet Access (HSPA) (3G), Time Division Synchronization Code Time Division-Synchronous Code Division Multiple Access (WCDMA) (2G/3G), GSM/Enhanced Data Rate only (Enhanced Data Rate for GSM Evolution-only, EDGE-only) (2G), Code only Division Multiple Access (Code Division Multiple Access-only, CDMA-only) (2G/3G), etc. It is important to note that the figure does not show access technologies with subscriptions less than one percent.

In this way, it can be seen from Figure 2 that with the progress of the times and the evolution of network technology, low-efficiency wireless access technologies are being refarmed into new technologies, such as GSM/UMTS being refarmed to LTE/NR. At this time, for the old access technologies (such as GSM/UMTS) that are not used by multi-mode terminals or have been refarmed to new access technologies, the embodiment of this application can try to skip these accesses as much as possible when searching for networks. Technical search.

Based on this, the embodiment of the present application provides a network search method. After obtaining the network standard information supported by the multi-mode terminal, it can be determined by self-learning of user usage and historical resident information within a certain period of time. The network search probability value of each candidate network standard in the network standard information; then according to the network search probability value of each candidate network standard, the network standard list to be searched corresponding to each search period is further determined, so that in each During the search period, the network search can be performed according to the determined list of network standards to be searched; in this way, wireless access technologies and/or frequency bands with low probability (that is, low network search probability) can be skipped, which can not only reduce the network The power consumption caused by the search can also shorten the network search time and achieve the purpose of quickly obtaining services.

Hereinafter, each embodiment of the present application will be described in detail with reference to the accompanying drawings.

In an embodiment of the present application, refer to FIG. 3, which shows a schematic flowchart of a network search method provided in an embodiment of the present application. As shown in Figure 3, the method may include:

S301: Obtain network standard information supported by the multi-mode terminal;

In the embodiment of the present application, the network standard information may include multiple candidate network standards based on the radio access technology and/or frequency bands supported by the radio access technology.

It should be noted that this method is applied to a network search device or a multi-mode terminal integrated with the network search device. Here, the multi-mode terminal can be, for example, a smart phone, a tablet computer, a notebook computer, a palmtop computer, a personal digital assistant (PDA), a portable media player (Portable Media Player, PMP), a navigation device, a wearable device , User Equipment (UE), mobile station (mobile station) and other devices with multi-mode capabilities.

It should also be noted that for multi-mode terminals, multi-mode terminals can support multiple candidate network standards. From the perspective of wireless access technology, when the multi-mode terminal is a dual-mode terminal, there are two candidate network standards at this time, such as GSM/UMTS, or GSM/LTE, or LTE/NR, etc.; When the modular terminal is a three-mode terminal, a four-mode terminal or even a more-mode terminal, take the four-mode terminal as an example. At this time, the candidate network standards can include four types, such as GSM/UMTS/LTE/NR, etc.; in addition, for The same wireless access technology, taking GSM as an example, from the point of view of the supported frequency bands, at this time, the candidate network standards can also include multiple, such as GSM-850/GSM-900/GSM-1800/GSM-1900, etc. .

S302: Determine the network search probability value of each candidate network standard in the network standard information;

It should be noted that after obtaining the network standard information supported by the multi-mode terminal, it is possible to determine each through self-learning of user usage and historical resident information within a certain period of time (usually more than a few months). The search probability value of a candidate network system, so as to subsequently determine which candidate network systems to skip.

Here, the network search probability value can also be called a ratio value or a ratio value, which is represented by a ratio, which specifically refers to a network search performed every search period of a certain candidate network standard. If the search probability value of a candidate network standard is 1/2, that is, the network search of the candidate network standard will be performed every two search cycles; if the network search probability value of the candidate network standard is 1/4, that is A network search of the candidate network standard is performed every four network search cycles. In the embodiment of the present application, the probability value of searching the network may be in a value range between 0 and 1.

It should be understood that the preset database can be regarded as a big data concept, and the preset database has historical resident information of the multi-mode terminal, and the historical resident information here is usually the mobility behavior of the multi-mode terminal in recent months. That is to say, the preset database is established according to the user's daily usage and user habits; through self-learning of the preset database, the network search probability value of each candidate network standard can be determined. Therefore, in some embodiments, the determining the network search probability value of each candidate network standard in the network standard information may include:

Furthermore, for the preset database, it can also be kept updated during the operation of the multi-mode terminal to ensure that it always has accurate historical resident information. In some embodiments, the method may further include:

Acquiring historical resident information of the multi-mode terminal;

According to the acquired historical residency information, the preset database is updated.

That is to say, in order to understand the mobility behaviors of multi-mode terminals in the past few months, to count which candidate network standards (such as which wireless access technology and frequency band combination) are more desirable for network search, you need to check the preset The database performs self-learning to obtain the network search probability value of each candidate network standard in the network standard information supported by the multi-mode terminal.

It should also be noted that the preset database can be classified into Public Land Mobile Network (PLMN) and entity (country); and for each operator category, there will be a corresponding preset database. As shown in FIG. 4, it shows a schematic diagram of the composition structure of a preset database provided by an embodiment of the present application. In Figure 4, the preset database is established on a specific PLMN. The preset database can be a UE-Mobility-Database, which includes GSM, UMTS, LTE, and NR. The historical camping information of a candidate network standard; from the perspective of wireless access technology (including GSM-RAT/UMTS-RAT/LTE-RAT/NR-RAT), the historical camping information at this time can include the total staying in the last x months Time statistics (Camping Duration statistics in last x months) and last camped/detected timestamp information (Last Camped/Detected timestamp), etc.; from the perspective of frequency bands (including GSM frequency band list/UMTS frequency band list/LTE-Band Band list/NR band list), at this time, the historical camping information can include the band number (Band number), the statistics of the total camping time in the last x months (Camping Duration statistics in last x months), and the last stay/detected The arrived timestamp information (Last Camped/Detected timestamp), etc.

In this way, according to the example of the preset database shown in Figure 4, the user can obtain the historical residence information for a long enough time (for example, x months) from a particular PLMN, so that the determination of the probability value of the search network is based on enough Statistics of historical data. Here, the process of determining the probability value of the search network may include one or more inputs and an output; among them, the one or more inputs may include: total residence time statistics, and/or, the last residence detection Timestamp information, and/or, pre-defined configuration information; an output is the network search probability value of the candidate network standard (wireless access technology/frequency band). That is to say, the network search probability value of the wireless access technology/frequency band can be determined according to the one or more inputs, and this is used as an output to subsequently determine the list of network standards to be searched corresponding to each search period.

S303: Determine, according to the network search probability value of each candidate network standard, a list of network standards to be searched corresponding to each search period;

It should be noted that the list of network standards to be searched may include one or more network standards. That is to say, after obtaining the search probability value of each candidate network standard, the list of network standards to be searched corresponding to each search period can be determined, and the list of network standards to be searched does not include all candidate networks. Standard: For candidate network modes with low search probability values, because they have a low probability of obtaining services, these low-probability candidate network modes can be skipped during part of the search period, so as to save power, The purpose of shortening the network search time.

S304: In each search period, perform a network search according to the determined list of network standards to be searched.

That is to say, in the process of network search, after the list of network standards to be searched corresponding to each search period is determined, for each search period, the network search operation can be performed using the list of network modes to be searched corresponding to the search period. .

Assuming that the first candidate network standard is any one of the multiple candidate network standards, if the search probability value of the first candidate network standard is less than 1, it indicates that the list of network standards to be searched corresponding to the partial search period is not included The first candidate network standard, then during this part of the search period, the network search operation will be performed using the list of network modes to be searched that does not include the first candidate network standard.

Refer to FIG. 5, which shows a schematic structural diagram of a network search working mode according to an embodiment of the present application. As shown in Figure 5, there are four types of wireless access technologies: NR/LTE/UMTS/GSM. Among them, GSM can also be called 2G access technology, and UMTS can also be called 3G access technology. The technology can include multiple frequency bands. Taking the NR technology as an example, it is assumed that there are four frequency bands such as a/b/x/y. Here, from the perspective of wireless access technology, the network search probability value of NR is equal to 1, the network search probability value of LTE is equal to 1, the network search probability value of UMTS is equal to 1/2, and the network search probability value of GSM is equal to 1/4; In terms of frequency band, the probability value of searching the network of a is equal to 1, the probability value of searching the network of b is equal to 1/2, the probability value of searching the network of x is equal to 1, and the probability value of searching the network of y is equal to 1/2; according to these network searching probability values, The list of network standards to be searched corresponding to each search period can be determined. For example, for wireless access technologies, the first search period only performs network searches on the list of network standards to be searched composed of NR and LTE, and the second search period only performs network searches on NR, The network search is performed on the list of network standards to be searched composed of LTE and UMTS. The third search cycle is only performed on the list of network standards to be searched composed of NR and LTE. The fourth search cycle is for the waiting search composed of NR, LTE, UMTS and GSM. The network standard list performs a network search; for the frequency band corresponding to the NR access technology, the first search cycle only performs a network search on the list of network standards to be searched composed of a and x, and the third search cycle also only performs a network search on the list of a and x to be searched The network standard list performs a network search. It can be seen from Figure 5 that the network search is still repeated at a certain time interval, but in each search cycle, the selected wireless access technology and frequency band will be searched according to the calculated network search probability value. For wireless access technologies and frequency bands with low network search probability values (the areas covered by gray in FIG. 5), these wireless access technologies and frequency bands will be skipped in this embodiment of the application.

In short, in the embodiment of this application, a preset database is established based on the historical resident information of the multi-mode terminal (ie, the user's daily usage), and then the preset database is studied and analyzed, and it can be found that it is more promising to obtain services For the high-probability candidate network standards, the search probability value of these high-probability candidate network standards should be correspondingly increased in the network search; at the same time, for the low-probability candidate network standards, these candidate network standards usually refer to the old ones. Access technology (GSM and UMTS, etc.) and has low network search performance. In network search, the search probability value of these low-probability candidate network standards can be reduced, and these low-probability candidate network standards can be skipped accordingly Search.

This embodiment provides a network search method by acquiring network standard information supported by a multi-mode terminal; wherein, the network standard information includes multiple types based on wireless access technology and/or frequency bands supported by wireless access technology. Candidate network standard; determine the network search probability value of each candidate network standard in the network standard information; determine the network standard list to be searched corresponding to each search period according to the network search probability value of each candidate network standard ; In each search period, perform a network search according to the determined list of network standards to be searched. In this way, the network search probability value of each candidate network standard is determined according to the historical resident information of the multi-mode terminal, and then the network search operation is performed according to the determined network search probability value, which can skip the low probability (ie, low search Network probability value) wireless access technology and/or frequency band, which can not only reduce the power consumption caused by network search, but also shorten the network search time to achieve the purpose of quickly obtaining services.

In another embodiment of the present application, refer to FIG. 6, which shows a schematic flowchart of another network search method provided by an embodiment of the present application. As shown in Figure 6, the method may include:

S601: Obtain network standard information supported by the multi-mode terminal;

It should be noted that the network standard information may include multiple candidate network standards based on wireless access technologies and/or frequency bands. Here, the frequency band refers to the frequency band information supported by the wireless access technology. Specifically, from the perspective of wireless access technology, candidate network standards can include multiple, such as GSM/UMTS/LTE/NR, etc.; and for each wireless access technology, from the perspective of frequency bands, candidate network standards There may also be multiple network standards. Taking GSM as an example, candidate network standards may include GSM-850/GSM-900/GSM-1800/GSM-1900, etc.

In this way, for these multiple candidate network standards, the search probability value of each network standard in the network standard information supported by the multi-mode terminal can be determined through self-learning of the preset database, so as to determine which ones to skip later Candidate network standard.

Value; it can also only include two search probability values, such as the first search probability value and the second search probability value, or the first search probability value and the third search probability value, or the second search probability Value and the third search probability value. In addition, the network search probability value based on the analysis information under each candidate network standard may also include more network search probability values, that is, the embodiment of the present application is not limited to the first network search probability value and the second network search probability. The value and the third search probability value are not limited here.

Here, the first network search probability value, the second network search probability value, and the third network search probability value may all be in a value range between 0 and 1. In actual applications, the first network search probability value, the second network search probability value, and the third network search probability value are specifically set based on historical experience, and the embodiment of the present application does not specifically limit it.

Understandably, whether it is the first search probability value, the second search probability value, or even the third search probability value, it is obtained based on the statistical analysis of the historical resident information in the preset database. The following will The determination methods are described separately.

In some embodiments, for S602, the statistical analysis of the historical resident information in the preset database to determine the network search probability value of each candidate network standard based on the analysis information may include:

Further, the determining the first network search probability value corresponding to each candidate network standard according to the statistical value of the total residence time under each candidate network standard may include:

It should be noted that the same preset range corresponds to the same first network search probability value, and different preset ranges correspond to different first network search probability values.

It should also be noted that the first candidate network standard and the second candidate network standard are any two candidate network standards among multiple candidate network standards; where,

If the statistical value of the total residence time under the first candidate network standard is greater than the statistical value of the total residence time under the second candidate network standard, and the first candidate network standard and the second candidate network standard correspond to different presets Range, the first network search probability value corresponding to the first candidate network standard is greater than the first network search probability value corresponding to the second candidate network standard.

Here, for each candidate network standard, the statistical value of the total residence time can be a percentage value (that is, the proportion between the total residence time under each candidate network standard and the total residence time under all candidate network standards) , It can also be a non-percentage value (that is, the total residence time under each candidate network standard). If the statistical value of the total residence time is in the form of a percentage value, then the at least one threshold should be set in the form of a percentage value; if the statistical value of the total residence time is in the form of a non-percentage value, then the at least one threshold should be set in the form of a non-percentage value. Set in the form of a percentage value. In the embodiment of the present application, the statistical value of the total residence time and the at least one threshold value will be described in detail in the form of a percentage value as an example.

It should be noted that the first network search probability value can be represented by R_Duration, and its determination is related to the statistics of the total residence time in the preset time period. Take 18 months as an example for the preset time period. From the perspective of wireless access technology, calculate the statistical value of the total residence time under each candidate network standard in 18 months, and then calculate the total residence time according to each candidate network standard. The statistical value of time determines the first network search probability value corresponding to each candidate network standard.

Exemplarily, the at least one threshold includes only the first threshold. At this time, assuming that the first threshold is 2%, if the statistical value of the total residence time under a certain candidate network standard is <= 2%, if the first network search probability value at this time can be set to 1/2, then The first search probability value corresponding to the candidate network standard can be 1/2; otherwise, if the statistical value of the total residence time under a certain candidate network standard is> 2%, if the first search probability value at this time can be Set to 1, then the first network search probability value corresponding to the candidate network standard can be set to 1. Specifically, as shown in Table 1, it shows an example of the mapping relationship between the statistical value of the total residence time and R_Duration under candidate network standards such as NR/LTE/UMTS/GSM.

Table 1

Exemplarily, the at least one threshold may further include a first threshold and a second threshold. At this time, it is assumed that the first threshold is 2% and the second threshold is 10%; then if the statistical value of the total residence time under a certain candidate network standard is <= 2%, if the probability value of the first search network at this time can be Set to 1/4, the first search probability value corresponding to the candidate network standard can be 1/4; otherwise, if the statistical value of the total residence time under a certain candidate network standard is <=10%, if this time The probability value of the first search network can be set to 1/2, then the probability value of the first search network corresponding to the candidate network standard can be 1/2; otherwise, if the statistical value of the total residence time under a certain candidate network standard >10%, if the first network search probability value at this time can be set to 1, then the first network search probability value corresponding to the candidate network standard can be set to 1. Specifically, as shown in Table 2, it shows an example of the mapping relationship between the statistical value of the total residence time and R_Duration under candidate network standards such as NR/LTE/UMTS/GSM.

Table 2

Further, the determining the second network search probability value corresponding to each candidate network standard according to the time stamp information of the last resident detection under each candidate network standard may include:

It should be noted that the same preset residence time period corresponds to the same second network search probability value, and different preset residence time periods correspond to different second network search probability values.

If the time stamp information of the last resident detection under the first candidate network standard is less than the time stamp information of the last resident detection under the second candidate network standard, and the first candidate network standard and the second candidate network The standards correspond to different preset residence time periods, and the second network search probability value corresponding to the first candidate network standard is greater than the second network search probability value corresponding to the second candidate network standard.

In the embodiment of the present application, the time stamp information of the last residency detection refers to "the time stamp information of the most recent residency detection". Here, the second network search probability value is represented by R_LastCD, and its determination is related to the time stamp information of the last residency detection. From the perspective of wireless access technology, by judging whether the most recently resident/detected timestamp information under each candidate network standard is within a preset time period, so as to determine the second search network corresponding to each candidate network standard Probability value.

Exemplarily, the at least one threshold may include a first threshold and a second threshold. At this time, it is assumed that the first threshold is 3 months and the second threshold is 12 months; then it can be obtained that the first preset residence time period is within the last 3 months, and the second preset residence time period is the latest 3-12 During the month, the third preset period of stay is beyond 12 months; at this time, if a certain candidate network standard is parked/being parked within the last 3 months (that is, within the first preset period of stay) Detected, that is, the time stamp information of the last residency detection falls within the last 3 months. If the second network search probability value at this time can be set to 1, then the second network search probability value corresponding to the candidate network standard It can be 1; otherwise, if a certain candidate network standard has not been parked/detected in the last 3 months but is parked in the last 3-12 months (that is, within the second preset period of stay) Stay/be detected, that is, the time stamp information of the last stay detection falls within the last 3-12 months. If the second network search probability value at this time can be set to 1/2, then the candidate network standard corresponds to The second network search probability value can be 1/2; otherwise, if a certain candidate network standard is parked/detected beyond 12 months (that is, within the third preset residence time period), it is The candidate network standard has not been resident/detected in the last 12 months. If the second network search probability value at this time can be set to 1/4, then the second network search probability value corresponding to the candidate network standard can be set Is 1/4. Specifically, as shown in Table 3, it shows an example of the mapping relationship between the time stamp that was recently camped on/detected and R_LastCD under candidate network standards such as NR/LTE/UMTS/GSM.

table 3

Correspondingly determine the predefined configuration value under each candidate network standard as the third network search probability value corresponding to each candidate network standard.

Here, the third network search probability value is represented by R_Predefine, and its determination is related to predefined configuration information (such as user configuration information). Perform statistical analysis on the historical resident information in the preset database, and then set the predefined configuration values under each candidate network standard by yourself. It should also be noted that the predefined configuration value is in the value range between 0 and 1. In actual applications, the predefined configuration values can be set on the baseband development side, or can be set by the user on the multimode terminal side, which is not specifically limited in the embodiment of the present application.

Exemplarily, for the GSM candidate network standard, the predefined configuration value can be set to 1/2; for the UMTS candidate network standard, the predefined configuration value can be set to 1; for the LTE candidate network standard, the predefined configuration value can be set to 1. ; For the NR candidate network standard, the predefined configuration value can be set to 1, and the predefined configuration value is the third network search probability value. Specifically, as shown in Table 4, it shows examples of predefined configuration values (ie, R_Predefine) for each candidate network standard such as NR/LTE/UMTS/GSM.

Table 4

In this way, after determining the parameter values of R_Duration, R_LastCD, and R_Predefine under each candidate network standard, the network search probability value of each candidate network standard can be determined according to these parameter values.

S603: For each candidate network standard, select the minimum value from at least two items included in the network search probability value based on the analysis information, and correspondingly determine the selected minimum value as the search for each candidate network standard. Network probability value;

It should be noted that for each candidate network standard, you can start from the first network search probability value (R_Duration), and/or the second network search probability value (R_LastCD), and/or the third network search probability value (R_Predefine) Wait for the minimum value of at least two items; then, the minimum value of each candidate network standard is correspondingly determined as the network search probability value of each candidate network standard.

From the perspective of wireless access technology, for the case that only two items are included, taking each candidate network standard including the first network search probability value and the second network search probability value as an example, the network search probability value is determined as follows As shown,

N=min(R_Duration,R_LastCD) (1)

Or, taking each candidate network standard including the first search probability value and the third search probability value as an example, the determination of the search probability value is as follows:

N=min(R_Duration,R_Predefine) (2)

Or, taking each candidate network standard including the second network search probability value and the third network search probability value as an example, the determination of the network search probability value is as follows:

N=min(R_LastCD,R_Predefine) (3)

It should be noted that in these three determination methods, the determination method corresponding to formula (1) is used in most cases; and compared with the determination method using formula (2) or formula (3), formula (1) is used It can better realize the technical effect of reducing power consumption and shortening the network search time.

From the perspective of wireless access technology, for the three-item case, taking each candidate network standard includes the first network search probability value, the second network search probability value, and the third network search probability value as an example, the search The determination of the network probability value is as follows,

N=min(R_Duration,R_LastCD,R_Predefine) (4)

Where, N represents the overall network search probability value under the candidate network standard, that is, the network search probability value corresponding to the candidate network standard in the foregoing embodiment. Here, formulas (1) to (4) indicate that the minimum value is selected from at least two items such as R_Duration, R_LastCD, and R_Predefine, and determined as the network search probability value corresponding to the candidate network standard. It should be noted that among the four determination methods, the technical effect achieved by formula (4) is the best, which can not only reduce power consumption, but also shorten the network search time, thereby reducing the network search delay.

Exemplarily, taking three parameter values as an example, as shown in FIG. 7, which shows a schematic flowchart of a network search probability value determination provided by an embodiment of the present application. In Figure 7, there are three inputs and one output. The three inputs can include: total residence time statistics 701, time stamp information 702 for the last residence detection, and predefined configuration information 703; one output is The network search probability value of the candidate network standard, that is, the network search probability value 704 of the wireless access technology/frequency band. In other words, based on these three inputs, the network search probability value of the wireless access technology/frequency band can be output.

Combining Table 1, Table 3 and Table 4, we can get the results of the search probability value as follows, and the network search working mode reflected by these search probability value results is shown in Figure 5; among them,

For the GSM candidate network standard, N_GSM=min(1/2,1/4,1/2)=1/4, which means that in every four search periods, only the fourth search period has a GSM network search;

For the UMTS candidate network standard, N_UMTS=min(1,1/2,1)=1/2, which means that in every two search periods, only the second search period has a UMTS network search;

For LTE candidate network standards, N_LTE=min(1,1,1)=1, indicating that there will be LTE network searches in every search period;

For the NR candidate network standard, N_NR=min(1,1,1)=1, indicating that there will be NR network searches in every search period.

Further, for a certain wireless access technology, from the perspective of frequency bands, the same calculation rules described above can also be used to determine the parameter values corresponding to each frequency band, which are represented by R_Duration', R_LastCD', and R_Predefine', respectively. The probability value is determined as follows,

N_Band_x=min(R_Duration’,R_LastCD’,R_Predefine’) (5)

Exemplarily, the results of the probability value of searching the net can be obtained as follows, and the working mode of the net search reflected by the results of the probability value of the net searching is still as shown in Fig. 5; wherein,

For the a-band candidate network standard, N_Band_a=1, indicating that there will be a-band network search in every search period;

For the b-band candidate network standard, N_Band_b=1/2, indicating that in every two search periods, only the second search period has a b-band network search;

For x-band candidate network standards, N_Band_x=1, indicating that there will be x-band network searches in each search period;

For the y-band candidate network standard, N_Band_y=1/2, which means that in every two search periods, only the second search period has a y-band network search.

In addition, the first network search probability value or the second network search probability value or the third network search probability value can also be directly determined as the network search probability value of each candidate network standard. In some embodiments, the method may further include:

When the network search probability value based on the analysis information only includes one of the following, the network search probability value of one of the items under each candidate network standard is correspondingly determined as the network search for each candidate network standard Probability value

It should be noted that when only one item (such as the first network search probability value) is included, the first network search probability value under each candidate network standard can also be correspondingly determined as the network search probability of each candidate network standard Value; or, when only one item (such as the second probability value of the network search) is included, the second probability value of the network search under each candidate network standard can be correspondingly determined as the network search probability of each candidate network standard Value; or, when only one item (such as the third network search probability value) is included, the third network search probability value under each candidate network standard can be correspondingly determined as the network search probability of each candidate network standard value.

It should also be noted that when only one item is included, since only the analysis information of one item is considered, the probability value of the search network obtained at this time may be biased, and the effect of shortening the network search time is not obvious. . In order to better shorten the network search time and achieve the purpose of quickly obtaining services, the embodiments of this application usually adopt at least two cases, or even three or more cases, to minimize the network search time and reduce Due to the power consumption brought by the network search, the purpose of quickly obtaining services is realized at the same time.

S604: Determine a list of network standards to be searched corresponding to each search period according to the network search probability value of each candidate network standard;

S605: In each search period, perform a network search according to the determined list of network standards to be searched.

Here, the list of network standards to be searched includes one or more network standards. That is to say, after obtaining the search probability value of each candidate network standard, the list of network standards to be searched corresponding to each search period can be determined, and the list of network standards to be searched does not include all candidate networks. Standard.

Assuming that the first candidate network standard is any one of the multiple candidate network standards, if the search probability value of the first candidate network standard is less than 1, then the first candidate network standard is not included in the list of to-be-searched network standards corresponding to the partial search period. A candidate network standard. Specifically, in some embodiments, for S605, the determining the list of network standards to be searched corresponding to each search period according to the network search probability value of each candidate network standard may include:

Correspondingly, for S605, in each search period, performing a network search according to the determined list of network standards to be searched may include:

It should be noted that for the GSM candidate network standard, if N_GSM=1/4, then the network search probability value of the candidate network standard is less than 1. At this time, in every four search periods, the first three search periods will not Perform the GSM network search operation; for the UMTS candidate network standard, if N_UMTS=1/2, then the network search probability value of the candidate network standard is also less than 1. At this time, in every two search periods, the previous search period is equal The UMTS network search operation will not be performed. In other words, for candidate network modes with low network search probability values, since they have a low possibility of obtaining services, these low-probability candidate network modes can be skipped during part of the search period.

Further, in some embodiments, after the determining the list of network standards to be searched corresponding to each search period, the method may further include:

That is to say, after the list of network standards to be searched corresponding to each search period is determined, the network standards included in the list of network standards to be searched can also be prioritized according to a preset priority strategy, such as NR- >LTE->UMTS->GSM and other priority ordering to get the priority list of the network standards to be searched; in this way, in each search cycle, according to the order of priority from high to low in the priority list of the network standards to be searched Select the network standard to be searched and perform the network search operation.

In addition, the preset priority strategy can also be combined with the determined network search probability value. In the case of different network search probability values, the network standards included in the search network standard list are prioritized according to the size of the search network probability value. ; But in the case of the same network search probability value, it will be sorted according to the priority order of NR->LTE->UMTS->GSM to get the priority list of the network standards to be searched; in this way, in each search cycle, according to In the priority list of the network standards to be searched, select the network standards to be searched and perform the network search operation in the order of priority from high to low, so as to make the search for the network standards to be searched with a high possibility of obtaining services preferentially searched, which can achieve The purpose of obtaining services quickly.

Further, in some embodiments, for S605, after performing a network search according to the determined list of network standards to be searched, the method further includes:

If a cell that can be camped on is found, camp on.

That is to say, in the process of network search, when a certain wireless access technology successfully searches the network, it will further determine the frequency band where the network search is successful under that wireless access technology; then determine whether it is in this frequency band. The cell that can be camped on can be searched, and when the cell that can be camped on can be searched, the cell camping will be performed and the network search operation will be ended.

Understandably, the embodiments of the present application can provide network search probability values (also called weight values) for wireless access technologies and frequency bands in multiple modes to detect more promising/preferred values during the network search stage. Wireless access technology and frequency bands. Here, the search probability value/weight value is obtained by self-learning based on user usage and historical resident statistical data within a certain period of time (for example, x months). For wireless access technologies and frequency bands with low probability (that is, low probability of searching the network), the embodiments of the present application can reduce power consumption by skipping these low probability wireless access technologies and frequency bands; for high probability (that is, High search probability value) wireless access technologies and frequency bands, the embodiment of the present application provides a higher proportion of searches on these high-probability wireless access technologies and frequency bands, so that services can be quickly obtained. Based on empirical data, the time consumption of search results in conventional frequency bands is roughly as follows: GSM is about 10-20 seconds, UMTS is about 10-20 seconds, LTE is about 5 seconds, and NR is about less than or equal to 5 seconds. Exemplarily, GSM and UMTS are low-probability wireless access technologies. Using the technical solution of this application can save up to 80% of power consumption; and GSM and UMTS are searching for services available in LTE/NR. The benefit is about 20-40 seconds.

That is to say, network search performance is one of the most important key indicators of multi-mode terminals, and for multi-mode terminals, it can enable multi-mode terminals to have better network search and selection performance and lower power consumption. In addition, the technical solution of this application can not only be applied to multi-mode terminals, but also applicable to chips. In particular, any modem chip set manufacturer can apply the technical solution of this application to build a big data concept in the chipset, and The data is analyzed to obtain more promising (ie, high probability) wireless access technologies and frequency bands, so as to achieve better network search performance.

This embodiment provides a network search method. The specific implementation of the foregoing embodiment is described in detail through the foregoing embodiment. It can be seen from the technical solution of the foregoing embodiment that the historical resident information of the multi-mode terminal is used to Determine the network search probability value of each candidate network standard, and then perform the network search operation according to the determined network search probability value, you can skip the low-probability (ie low network search probability value) wireless access technology and/or The frequency band can not only reduce the power consumption caused by the network search, but also shorten the network search time to achieve the purpose of quickly obtaining services.
