Description

[0001] This application is a divisional application, the original application number is 201911208726.3, the original application date is November 30, 2019, and the entire contents of the original application are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the field of mobile communication technology, in particular to a cell measurement method, a measurement device, a terminal device, a chip and a storage medium. BACKGROUND

[0003] In the prior art, the terminal device starts to perform inter-frequency inter-system neighbor cell measurement from the condition of meeting the inter-frequency measurement condition, and continues until cell reselection occurs, which often takes a period of time. The continuous measurement in this period of time is unnecessary in most cases. The terminal device often continues for a certain period of time from network drop-out to searching for the network again. The network search performed by the terminal device in the area without network coverage is unnecessary. Therefore, the cell measurement and network search in the prior art cause the terminal device to have large power consumption. SUMMARY

[0004] Embodiments of the present application provide a cell measurement method, a measurement device, a terminal device, a chip and a storage medium to solve the problem of large power consumption of the terminal device caused by cell measurement and network search in the prior art.

[0005] Therefore, the first aspect of the present application provides a cell measurement method, which can include: when the terminal device camps on a first cell, if the terminal device determines that it is in a target environment, the terminal device can obtain the signal strength of the first cell in which the terminal device camps. The target environment is a fixed place or a fixed route identified in advance by the terminal device. Then, if the obtained signal strength is lower than a first threshold and higher than a second threshold, the terminal device performs second cell measurement, and the second cell is a cell determined by the terminal device according to the target environment; if the obtained signal strength is lower than the second threshold, the terminal device performs third cell measurement, and the third cell includes the neighbor cell of the first cell. Because the present application can learn the cell corresponding to the target environment in advance. In this way, if the terminal device is in the target environment and the signal strength of the currently camped cell is lower than the first threshold and higher than the second threshold, the terminal device can perform cell measurement according to the learned cell. Thus, invalid measurement can be effectively avoided, and the power consumption of the terminal device is reduced. In addition, when the second cell does not meet the condition, the terminal device can search for the third cell to expand the search range.

[0006] Optionally, in some embodiments of the present application, the terminal device comprises a first processor and a second processor. It can be understood that the first processor is configured to generate the target measurement strategy, and the second processor is configured to execute the target measurement strategy. The first processor of the terminal device sends the target measurement strategy to the second processor of the terminal device. The target measurement strategy comprises at least one of the first threshold, the second threshold, and the cell information corresponding to the at least one second cell, and the second threshold is smaller than the first threshold. The cell information corresponding to the at least one second cell comprises at least one of the frequency corresponding to the at least one second cell and the cell identifier corresponding to the at least one second cell. In this way, the second processor can perform cell measurement according to the information included in the target measurement strategy. Since the target measurement strategy is the measurement strategy corresponding to the target environment learned by the terminal device in advance, invalid measurement can be effectively avoided, and the power consumption of the terminal device is reduced.

[0007] Optionally, in some embodiments of the present application, the terminal device determines that it is in the target environment, which can comprise: obtaining first information, and if the first information matches the second information, the terminal device determines that it is in the target environment; wherein the second information is the description information of the target environment; and the description information is determined by the terminal device according to the target environment. In this way, since the terminal device can obtain the description information of the target environment in advance and associate the description information with the target environment, after the terminal device obtains the first information of the current environment, the terminal device can perform information matching according to the description information and the first information, so as to accurately identify whether the terminal device is in the fixed environment.

[0009] Optionally, in some embodiments of the present application, if the measurement result of the second cell satisfies the cell switching condition, the cell in which the terminal device resides is switched from the first cell to the second cell; and if the measurement result of the third cell satisfies the cell switching condition, the cell in which the terminal device resides is switched from the first cell to the third cell. It can be understood that the switching herein can be understood as switching or reselecting, i.e., switching when the terminal device is in a connected state, and reselecting when the terminal device is in an idle state. In this way, after the terminal device performs cell measurement in the manner described above, the terminal device can quickly obtain a cell that satisfies the cell switching condition, thereby improving the efficiency of cell switching.

[0010] Optionally, in some embodiments of the present application, the target measurement strategy can further include a measurement priority corresponding to the at least one second cell. In this way, the performing the second cell measurement by the terminal device can include measuring the second cell according to the measurement priority corresponding to the at least one second cell. Because the terminal device can preferentially measure the cell with a higher measurement priority, the measurement efficiency is improved, and the terminal power consumption is reduced.

[0011] Optionally, in some embodiments of the present application, when the target environment is a fixed place, the terminal device collects information in a specified time period, and the collected information is used as the description information; the specified time period has a corresponding relationship with the fixed place. In this way, because the user usually stays in the fixed place for a certain time period, the description information of the fixed place can be accurately obtained by collecting the information in this time period.

[0012] Optionally, in some embodiments of the present application, when the target environment is a fixed route, the terminal device collects information during the period from leaving a first fixed place to entering a second fixed place, and the collected information is used as the description information of the fixed route. In this way, because the fixed route in the present application is a route composed of different fixed places, the description information of the fixed route can be accurately obtained by detecting the leaving of the fixed place and the entering of the fixed place.

[0013] The second aspect of the present application provides a cell measurement method, which can include: when the terminal device stays in a first cell, if the terminal device determines that it is in a target environment, the terminal device can obtain the signal strength of the first cell in which the terminal device stays. The target environment is a fixed place or a fixed route identified in advance by the terminal device. Then, if the obtained signal strength is lower than a first threshold, the terminal device performs a second cell measurement, and the second cell is a cell determined by the terminal device according to the target environment. Because the present application can learn the cell corresponding to the target environment in advance, if the terminal device is in the target environment and the signal strength of the currently stayed cell is lower than the first threshold, the cell measurement can be performed according to the learned cell. Thus, invalid measurement can be effectively avoided, and the power consumption of the terminal device is reduced.

[0014] Optionally, in some embodiments of the present application, the terminal device comprises a first processor and a second processor. It can be understood that the first processor is configured to generate the target measurement strategy, and the second processor is configured to execute the target measurement strategy. The first processor of the terminal device sends the target measurement strategy to the second processor of the terminal device. The target measurement strategy comprises at least one of the first threshold and the cell information corresponding to the at least one second cell, and the cell information corresponding to the at least one second cell comprises at least one of the frequency corresponding to the at least one second cell and the cell identifier corresponding to the at least one second cell. In this way, the second processor can perform cell measurement according to the information included in the target measurement strategy. Since the target measurement strategy is the measurement strategy corresponding to the target environment learned by the terminal device in advance, invalid measurement can be effectively avoided, and the power consumption of the terminal device is reduced.

[0015] Optionally, in some embodiments of the present application, the terminal device determines that it is in the target environment, which can comprise: obtaining first information, and if the first information matches second information, the terminal device determines that it is in the target environment; wherein the second information is description information of the target environment; and the description information is determined by the terminal device according to the target environment. In this way, since the terminal device can obtain the description information of the target environment in advance and associate the description information with the target environment, after the terminal device obtains the first information of the current environment, the terminal device can perform information matching according to the description information and the first information, so as to accurately identify whether the terminal device is in the fixed environment.

[0016] Optionally, in some embodiments of the present application, the description information can be one or more of a WiFi name, an identifier of a serving cell, a signal strength of the serving cell, an identifier of a neighbor cell of the serving cell, and a signal strength of the neighbor cell.

[0017] Optionally, in some embodiments of the present application, if the measurement result of the second cell satisfies a cell handover condition, the cell in which the terminal device resides is switched from the first cell to the second cell. It can be understood that the switching herein can be understood as switching or reselecting, i.e., switching when the terminal device is in a connected state, and reselecting when the terminal device is in an idle state. In this way, after the terminal device performs cell measurement in the manner described above, the terminal device can quickly obtain a cell that satisfies the cell handover condition, thereby improving the efficiency of cell handover.

[0018] Optionally, in some embodiments of the present application, the target measurement strategy can further comprise a measurement priority corresponding to the at least one second cell. In this way, the terminal device performing the second cell measurement can comprise: the terminal device performing measurement on the at least one second cell according to the measurement priority corresponding to the at least one second cell.

For example, when taking a photo, the shutter is opened, the light is transmitted to the camera photosensitive element through the lens, the light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing to convert it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image.

[0082] The camera 293 is configured to capture still images or videos. An object generates an optical image through a lens and projects it onto a photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, and then transmits the electrical signal to the ISP to convert it into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format. In some embodiments, the terminal device 200 can include one or N cameras 293, where N is a positive integer greater than 1.

The terminal device 200 can also calculate the position of the touch according to the detection signal of the pressure sensor 280A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation instructions. For example, when a touch operation with a touch operation intensity less than a first pressure threshold is applied to a short message application icon, an instruction to view short messages is executed.

[0111] It should be noted that the terminal devices in this application may include mobile phones, tablets, laptops, ultra-mobile personal computers (UMPCs), handheld computers, netbooks, personal digital assistants (PDAs), wearable terminal devices, or smartwatches, etc. The embodiments of this application do not impose special restrictions on the specific form of the terminal devices.

[0112] Architecture of an operating system

[0113] The terminal device in this application may be an Android operating system, an iOS operating system, or other possible operating systems; this application does not limit this.

[0114] The following explanation uses the Android operating system as an example. FIG. 3 The diagram shown is a structural block diagram of a possible Android operating system terminal device provided in an embodiment of this application. FIG. 3 In this context, the terminal device may include two parts: an application processor and a modem, and the application processor and the modem exchange information.

[0115] The application processor architecture mainly consists of three layers: the application layer, the application framework layer, and the kernel layer (e.g., the Linux kernel layer).

[0116] Furthermore, the application layer includes various applications within the Android operating system (such as system applications and third-party applications).

[0117] The application framework layer is the framework for applications. Developers can build applications based on the application framework layer while adhering to the development principles of the application framework. The application framework layer may include a connectivity manager, a telephony manager, and a radio interface layer (RIL), among others.

[0118] The kernel layer is the operating system layer of the Android operating system. Based on the Linux kernel, the kernel layer provides core system services and hardware-related drivers for the Android operating system.

[0119] like FIG. 3 As shown, a modem may include a communication protocol stack, specifically a control plane protocol stack and a user plane protocol stack. The user plane protocol stack is the protocol suite used for user data transmission, and the control plane protocol stack is the protocol suite used for system control signaling transmission.

[0120] The control plane protocol stack includes: non-access stratum (NAS), radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, media access control address (MAC) layer, and physical layer (PHY), etc.; the user plane protocol stack may include: service data adaptation protocol layer, packet data convergence protocol layer, radio link control layer, media access control address layer, and physical layer, etc.

[0121] The embodiments of this application can be run in FIG. 3 In the operating system architecture shown.

[0122] It is understood that the terminal device pre-stores a preset network selection policy (equivalent to the preset measurement policy or preset network search policy in this application) in the application framework layer or modem. If the preset network selection policy is stored in the application framework layer, then because an adapter matching the RIL is configured in the modem (…),… FIG. 3The preset network selection strategy in the application framework layer can be transmitted to the NAS by modulating the communication between the adapter in the modem and the RIL, so that the application can perform the acquisition process of the target network selection strategy (i.e., equivalent to the target measurement strategy or the target search network strategy in the application) in the NAS, and perform the network selection process (i.e., equivalent to the cell measurement or the network search in the application) in the RRC according to the target network selection strategy after the target network selection strategy is acquired.

[0123] In the prior art, the power consumption of the terminal device includes the power consumption of the application processor and the modem. The power consumption of the modem mainly includes the standby power consumption and the data service power consumption. The standby power consumption and the data service power consumption can be caused by the network search and the cell measurement.

[0124] The network search in the prior art can include various cases. For example, the terminal device can periodically acquire the signal level value or the signal quality value of the current cell in which the terminal device is camped, and if it is determined that the terminal device meets the inter-frequency measurement condition according to the acquired signal level value or the signal quality value, the terminal device performs measurement on the inter-frequency neighbor cell and the inter-system neighbor cell. For another example, the terminal device continuously searches for the network in the case of network drop. For another example, if the network in which the terminal device is currently camped is not the highest standard network supported by the terminal device, the terminal device continuously searches for the highest standard network. For example, the highest standard network supported by the terminal device is 4G, and if the network in which the terminal device is currently camped is a 3G network, the terminal device continuously searches for the 4G network. The inter-frequency measurement condition can be Srxlev<=SnonIntraSearchP, or Squal<=SnonIntraSearchQ. Srxlev represents the acquired signal level value, Squal represents the acquired signal quality value, SnonIntraSearchP represents the level threshold of the inter-frequency and inter-system measurement, and SnonIntraSearchQ represents the quality threshold of the inter-frequency and inter-system measurement. The definitions of the parameters are the same as those defined in the 3GPP TS36.304 standard.

[0125] The network search in the prior art has problems: the terminal device starts to measure the inter-frequency neighbor cell and the inter-system neighbor cell from the time when the terminal device meets the inter-frequency start measurement condition, and continues to measure until cell reselection, which takes a period of time, and most of the measurement in this period of time is unnecessary, thereby causing waste of system resources and large power consumption of the terminal device. In addition, the terminal device loses network connection and then searches for network again, and in this period of time, the terminal device can be in a region without network coverage, and continuous network search in this period of time causes waste of system resources and large power consumption, and the terminal device cannot connect to the network, and therefore the network search is meaningless. In addition, some regions can only have 3G network coverage and no 4G network coverage. When the terminal device is in these regions, the terminal device continuously searches for 4G network, which only causes waste of large power consumption and is meaningless.

[0126] The present application is based on learning, identifying and predicting the characteristics of the wireless network signals of fixed lines or fixed locations, and then optimizing terminal network search and cell measurement, thereby saving terminal power consumption.

[0127] The present application provides various embodiments, which are described as follows.

[0128]

Technical scheme of cell measurement

[0129] FIG. 4 A flowchart of a cell measurement method in the embodiments of the present application is shown. The method is applied to a terminal device. In some embodiments, a user can start the intelligent network selection function in the manner shown in FIG. 10B 、 FIG. 10D or FIG. 10E , and then the terminal device performs the cell measurement method in the present application. In other embodiments, the terminal device can also automatically perform the cell measurement method in the embodiments of the present application. In other embodiments, when the terminal device detects that the network signal quality is poor, the user can be prompted whether to perform the cell measurement method in the embodiments of the present application. The present application does not limit the starting mode of the cell measurement.

[0130] When the terminal device is normally connected to the access network device, the terminal device selects a cell to camp on. The following describes the case where the terminal device camps on a first cell.

[0131] As shown in FIG. 4 , the cell measurement method in the embodiments of the present application can include the following steps:

[0132] 401. The terminal device determines that it is in a target environment.

[0133] After the cell measurement scheme provided in the embodiments of the present application is enabled, the terminal device determines whether it is currently in the target environment.

[0134] The target environment is a fixed place or a fixed route identified by the terminal device in advance. The fixed place or the fixed route is related to the behavior of the user. For example, the fixed place is a place where the user frequently moves, such as home, office, and the like; and the fixed route is a route frequently traveled by the user, such as a route traveled by the user to and from work.

[0135] In some embodiments, the target environment can be identified by the terminal device through collected description information. For example, the terminal device can obtain information about the fixed place or the fixed route in an application program.

[0136] There are many ways for the terminal device to determine the target environment.

[0137] In some embodiments, the terminal device can assume that the user is in the fixed place within a time period. For example, it can be assumed that the user is at home from 8 pm to 6 am; or it can be assumed that the user is at the office from 9 am to 12 am.

[0138] In other embodiments, the terminal device can assume that the user is in the fixed route when leaving the fixed place. For example, it can be assumed that the user is in the route between home and the office when the terminal device leaves home.

[0139] In other embodiments, the terminal device can assume that the user is in the fixed route when leaving the fixed place within a specific time. For example, it can be assumed that the user is in the route between home and the office when the terminal device leaves home from 7 am to 8 am.

[0140] In other embodiments, the terminal device can obtain first information, and then determine whether the first information matches second information, and if so, it can be determined that the terminal device is in the target environment.

[0141] The first information can be information about the environment in which the terminal device is currently located. In some embodiments, the first information can be cell information of a cell in which the terminal device is currently located. In other embodiments, the first information can be a WiFi name (also referred to as a service set identifier (SSID)) to which the terminal device is currently connected. The embodiments of the present application do not limit the specific content of the first information.

[0142] It can be understood that the second information is description information of the target environment; and the description information of the target environment can include at least one of description information of a cell and description information of a wireless fidelity (WiFi).

[0143] It should be understood that the description information of the target environment described above is determined by the terminal device according to the target environment, and the collection manner of the description information can refer to subsequent embodiments, which will not be described here.

[0144] Further, the description information of the cell can include description information of one or more cells.

[0145] It should be noted that the description information of the cell can include, but is not limited to, one or more of the following: an identifier of the serving cell (which can also be referred to as a mobile network cell signal fingerprint), a signal strength of the serving cell, an identifier of a neighbor cell of the serving cell, and a signal strength of the neighbor cell.

[0146] The description information of the WiFi can include description information of one or more WiFi.

[0147] It should be noted that the description information of the WiFi can include, but is not limited to, one or more of the following: a WiFi name and a signal strength of the WiFi. The WiFi name can include at least one of a name of a WiFi to which the terminal device is connected and a name of another WiFi that can be scanned by the terminal device when the terminal device is connected to the WiFi; and the signal strength of the WiFi can include at least one of a signal strength of the WiFi and a signal strength of the other WiFi.

[0148] For example, if the first information obtained by the terminal device is at least one of a signal strength, an identifier, and a name, the terminal device can determine whether at least one of the signal strength, the identifier, and the name included in the second information matches, and if there is at least one match, it can be determined that the terminal device is in the target environment. The at least one match can include: signal strength matching, or identifier matching, or name matching, or both signal strength and identifier matching, or both identifier and name matching, or both signal strength and name matching, or all of signal strength, identifier, and name matching.

[0149] If the first information obtained by the terminal device is a signal strength, the terminal device can determine whether the signal strength is close to the signal strength included in the second information, and if it is close, it can be considered that the signal strength matches.

[0150] If the first information obtained by the terminal device is an identifier, the terminal device can determine whether the identifier is the same as the identifier included in the second information, and if it is the same, it can be considered that the identifier matches.

[0151] If the first information obtained by the terminal device is a name, the terminal device can determine whether the name is the same as the name included in the second information, and if it is the same, it can be considered that the name matches.

[0152] 402、The terminal device obtains a signal strength of a first cell in which the terminal device resides.

[0153] When the terminal device determines to be in the target environment, the terminal device can acquire a signal strength of a first cell currently camped.

[0154] In the embodiments of the present application, the signal strength can include a reference signal receiving power (RSRP).

[0155] Of course, the signal strength in the present application can also be a signal quality value, and accordingly, the threshold involved in the subsequent can be a threshold value corresponding to the signal quality value. The signal quality value can include the following parameters: signal to interference plus noise ratio (SINR), reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), or received signal strength indication (RSSI), etc.

[0156] 403、When the signal strength of the first cell is lower than the first threshold, the terminal device performs a second cell measurement.

[0157] If the signal strength of the first cell acquired by the terminal device is lower than the first threshold, the terminal device can perform a second cell measurement.

[0158] The second cell is a cell identified and determined by the terminal device in advance according to the network signal characteristics of the target environment.

[0159] In some embodiments, the first threshold and the cell information corresponding to the at least one second cell can be acquired from a target measurement strategy. The target measurement strategy can be generated by a first processor and sent to a second processor, and the second processor is used to execute the target measurement strategy. The first processor and the second processor can be the same processor, or can be different processors.

[0160] It can be understood that the cell information corresponding to the second cell includes at least one of a frequency corresponding to the second cell and a cell identifier corresponding to the second cell.

[0161] Further, the target measurement strategy can further include a measurement priority corresponding to the at least one second cell.

[0162] For example, the measurement priorities of the cell 1, the cell 2 and the cell 3 are high to low, then the cell 1 can be measured first, the cell 2 can be measured second, and the cell 3 can be measured last in the process of the subsequent cell measurement.

[0163] In some optional embodiments, after the step 403, the embodiments of the present application can further include: when the measurement result of the second cell satisfies the cell switching condition, the cell in which the terminal device is located is switched from the first cell to the second cell.

[0164] It can be understood that the switching in the present application can include reselection and switching. If the terminal device is switched, the terminal device also needs to report the measurement report to the network.

[0165] Optionally, after the step 402 is performed, the step 404 can be further performed.

[0166] 404. When the signal strength of the first cell is lower than the first threshold and higher than the second threshold, the terminal device performs the second cell measurement.

[0167] When the signal strength of the first cell is lower than the first threshold, the terminal device can further judge whether the signal strength of the first cell is higher than the second threshold, and if yes, the terminal device can perform the second cell measurement.

[0168] The second cell is a cell selected from the cells required to be measured in the existing standard.

[0169] The specific content of the cell measurement in the step 403 and the step 404 can refer to the subsequent embodiments shown in the FIG. 5 or FIG. 6 , and will not be described here.

[0170] Optionally, after the step 402 is performed, the step 405 can be further performed.

[0171] 405. When the signal strength of the first cell is lower than the second threshold, the terminal device performs the third cell measurement.

[0172] When the signal strength of the first cell is lower than the first threshold, the terminal device can further judge whether the signal strength of the first cell is lower than the second threshold, and if yes, the terminal device can perform the third cell measurement.

[0173] In some embodiments, the third cell is all the neighboring cells of the currently camped cell, that is, the third cell is the cell which needs to be measured according to the existing standard. In other embodiments, the third cell is all the neighboring cells of the currently camped cell except the second cell. The advantage of this way is that when the second cell does not meet the cell handover condition, the terminal device can expand the search range.

[0174] It can be understood that the first threshold, the second threshold and the cell information corresponding to the at least one second cell can also be acquired from the target measurement strategy. The specific content of the target measurement strategy can refer to the embodiments shown in FIG. 5 or FIG. 6 , and will not be described here.

[0175] In other embodiments, the embodiments of the present application can also include: when the measurement result of the second cell meets the cell handover condition, the cell in which the terminal device camps is switched from the first cell to the second cell; and when the measurement result of the third cell meets the cell handover condition, the cell in which the terminal device camps is switched from the first cell to the third cell.

[0176] Through the above-mentioned embodiments, the present application can learn the cell corresponding to the target environment in advance. In this way, if the terminal device is in the target environment and the signal strength of the currently camped cell is lower than the first threshold, the cell measurement can be performed according to the learned cell. Invalid measurement can be effectively avoided, and the power consumption of the terminal device is reduced.

[0177]

Technical scheme of collecting description information

[0178] In some embodiments, the user can start the intelligent network selection function in the manner shown in FIG. 10B , FIG. 10D or FIG. 10E , and then the terminal device performs the process of collecting the description information in the present application. In other embodiments, the terminal device can automatically collect the description information.

[0179] In some embodiments, the terminal device can assume that the user is in a fixed place within a period of time, so the terminal device can collect the description information within the period of time. For example, it can be assumed that the user is at home between 2 am and 7 am. In this way, the terminal device can collect the description information within this period of time.

[0180] Of course, the present application can also collect the description information within this period of time for consecutive days when the user is in a fixed place. For example, the description information is collected within this period of time from Monday to Friday.

[0181] In other embodiments, the terminal device can start collecting the descriptive information when the user leaves a fixed location and stop collecting the descriptive information when the terminal device determines that the user enters another fixed location. For example, assume that the user leaves home and the terminal device starts collecting the descriptive information. The terminal device stops collecting the descriptive information when the terminal device determines that the user enters the office. The descriptive information is descriptive information about the route between the home and the office.

[0182] In other embodiments, the terminal device can start collecting the descriptive information when the user leaves a fixed location. If the terminal device determines that the user enters another fixed location within a certain time period, the descriptive information collected within the certain time period is reliable descriptive information and can be used to describe the route between the two fixed locations. If the terminal device determines that the user does not enter another fixed location within the certain time period, the terminal device stops collecting the descriptive information and the descriptive information collected within the certain time period is not reliable descriptive information and cannot be used to describe the route between the two fixed locations.

[0183] For example, assume that the user leaves home and the terminal device starts collecting the descriptive information. If the terminal device determines that the user enters the office within 50 minutes, the descriptive information collected within the 50 minutes is reliable descriptive information and can be used to describe the route between the home and the office.

[0184] In other embodiments, the terminal device can start collecting the descriptive information when the user leaves a fixed location within a certain time period. For example, if the user leaves home between 7:00 AM and 8:00 AM, the terminal device assumes that the user is on a fixed route between the home and the office and starts collecting the descriptive information when the user leaves home.

[0185] In other embodiments, the terminal device can assume that the user is on a fixed route within a certain time period and the terminal device can collect the descriptive information within the certain time period. For example, the terminal device can assume that the user is on a fixed route between 8:00 AM and 10:00 AM and the terminal device can collect the descriptive information between 8:00 AM and 10:00 AM. The above-described manner of collecting the descriptive information is merely illustrative and the present application does not limit the manner of collecting the descriptive information.

[0186] In the above-described embodiments of collecting the descriptive information, the collected descriptive information is associated with a fixed location or a fixed route.

[0187] For example, assuming the fixed place is a home, the terminal device collects the description information of the cell and the description information of the WiFi in a certain time period, and associates the information with the home. For example, the terminal device can continuously collect the description information for several days, and select the strongly related description information. For example, the terminal device can detect the WiFi name "My Home" for several days in this time period, and associate the name with the home. When the terminal device detects "My Home" again, it can be determined that the terminal device is currently in the fixed place of the home.

[0188] It should be noted that, in the process of collecting the description information, repeated information can be collected, for example, the same cell identifier or the same WiFi name can be collected. In this case, only one piece of information can be retained, and the repeated information can be removed, so as to avoid information redundancy. For example, the same WiFi name can be collected twice, and only one WiFi name can be retained.

[0189] The collected description information can include at least one of the description information of the cell and the description information of the WiFi. The description information of the cell can be one or more of the identifier of the serving cell in which the terminal device resides, the signal strength of the serving cell, the identifier of the neighboring cell of the serving cell, and the signal strength of the neighboring cell. The description information of the WiFi can be one or more of the WiFi name to which the terminal device is connected, the WiFi signal strength to which the terminal device is connected, the name of the other WiFi that can be scanned when connected to the WiFi, and the signal strength of the other WiFi.

[0190] According to the above-described embodiments, the at least one corresponding description information in the fixed place or the fixed route can be collected in advance, so that whether the terminal device is in the fixed place or the fixed route can be accurately identified based on the collected description information.

[0191]

Technical scheme of cell measurement

[0192] In some embodiments, the user can start the intelligent network selection function in the manner shown in FIG. 10B , FIG. 10D or FIG. 10E , and then the terminal device executes the cell measurement method in the present application. In other embodiments, the terminal device can also automatically execute the cell measurement method shown in the embodiments of the present application. In other embodiments, when the terminal device detects that the network signal quality is poor, the user can be prompted whether to execute the cell measurement method shown in the embodiments of the present application.

[0193] As shown in FIG. 5 , it is a flowchart of the method for cell measurement in the embodiments of the present application. The method is applied to a terminal device, and can include the following steps:

[0194] 501、detect whether the terminal device is in a fixed place or a fixed route.

[0195] It can be understood that the fixed place or the fixed route is related to the behavior of the user. For example, the fixed place is a place where the user often moves, such as home, office, etc.; the fixed route is a route that the user often takes, such as a route that the user takes to go to work. The specific method of detection can refer to step 401, which will not be repeated here.

[0196] 502、when the terminal device is in a fixed place, obtaining a target measurement strategy from a preset measurement strategy.

[0197] In an optional solution, the terminal device obtains the target measurement strategy from the preset measurement strategy according to the fixed place and a first cell in which the terminal device currently resides.

[0198] The target measurement strategy can be generated by a first processor and sent to a second processor, and the second processor is configured to execute the target measurement strategy. The first processor and the second processor can be the same processor or different processors.

[0199] The target measurement strategy includes a preset triggering condition corresponding to a plurality of cells to be measured. It can be understood that the plurality of cells to be measured corresponds to at least one second cell in the present application.

[0200] Further, the target measurement strategy can further include at least one of cell information corresponding to the plurality of cells to be measured; the cell information corresponding to the plurality of cells to be measured includes at least one of frequency corresponding to the plurality of cells to be measured and cell identifier corresponding to the plurality of cells to be measured. Of course, the target measurement strategy can further include at least one of measurement priority, measurement interval and network type of the plurality of cells to be measured.

[0201] 503、determine whether the first cell currently resided by the terminal device is included in the plurality of cells to be measured.

[0202] In the case where the first cell is not included in the plurality of cells to be measured, steps 504 to 506 are executed;

[0203] In the case where the first cell is included in the plurality of cells to be measured, steps 505 and 506 are executed.

[0204] 504、switch the first cell to one of the plurality of cells to be measured.

[0205] It can be understood that the application can directly perform cell measurement on multiple cells which need to be measured, so as to switch to one cell which meets the cell switching condition. Alternatively, the application can determine whether cell measurement is needed by using a network-configured measurement threshold value, and if cell measurement is needed, perform cell measurement on multiple cells which need to be measured, so as to switch to one cell which meets the cell switching condition.

[0206] 505. Obtain the signal strength of the first cell in which the terminal device currently resides.

[0207] In the embodiment of the application, the signal strength can include the following parameters: reference signal received power. Of course, the signal strength in the application can also be a signal quality value, and accordingly, the threshold involved in the subsequent can be a threshold value corresponding to the signal quality value. The signal quality value can include the following parameters: signal to interference plus noise ratio, reference signal received power, reference signal received quality, or received signal strength, etc.

[0208] 506. Determine whether the signal strength of the first cell meets a preset triggering condition.

[0209] The preset triggering condition can include but is not limited to the following conditions:

[0210] (1) The preset triggering condition includes: the signal strength is less than or equal to a first threshold.

[0211] (2) In the case where the target measurement strategy includes the measurement priorities of multiple cells which need to be measured, the preset triggering condition includes: the current cell does not belong to the cell corresponding to the highest measurement priority in the target measurement strategy, and the signal strength is less than or equal to the first threshold.

[0212] (3) The preset triggering condition includes: the signal strength is less than or equal to the first threshold, and the signal strength is greater than or equal to a second threshold; the first threshold is greater than the second threshold.

[0213] The first threshold and the second threshold are set according to empirical values, which can be adjusted according to the actual needs of users, and are not specifically limited in the embodiment of the application.

[0214] In the case where the signal strength of the first cell meets the preset triggering condition, step 507 is performed.

[0215] In the case that the signal strength of the first cell does not satisfy the preset triggering condition, the third cell measurement is performed. In some embodiments, the third cell is all the neighboring cells of the currently camped cell, that is, the third cell is the cell which needs to be measured as specified in the existing standard. In other embodiments, the third cell is all the neighboring cells of the currently camped cell except the second cell. In this way, when the second cell does not satisfy the cell handover condition, the terminal device can expand the search range.

[0216] 507. Perform cell measurement according to the cell information of the multiple cells which need to be measured to obtain measurement results.

[0217] In the embodiments of the present application, the multiple cells which need to be measured can be in many ways.

[0218] In one embodiment, the multiple cells which need to be measured can be the cells which have a longer camped time or a larger camped number of times when the terminal device is in a fixed place, or the cells with better service quality.

[0219] In another embodiment, the multiple cells which need to be measured can be the first N cells which have a longer camped time when the terminal device is in a fixed place, or the first N cells which have a larger camped number of times. N can be a preset value.

[0220] If the cell information includes the cell identifier, the terminal device can determine the cell according to the cell identifier, and then perform cell measurement on the cell to obtain measurement results.

[0221] If the cell information includes the frequency, the terminal device can perform cell measurement on the cell corresponding to the frequency to obtain measurement results.

[0222] If the cell information includes the cell identifier and the measurement priority, the terminal device can determine multiple cells according to the cell identifier, and then perform cell measurement on the multiple cells in descending order of the measurement priority to obtain measurement results.

[0223] If the cell information includes the cell identifier and the measurement interval, the terminal device can determine the cell according to the cell identifier, and then perform cell measurement on the cell according to the measurement interval to obtain measurement results.

[0224] In the prior art, if the terminal device is not in the most network mode supported by the terminal device, the terminal device will first perform cell measurement in the highest network mode in the process of performing cell measurement on the neighboring cell. However, if the network mode supported by the neighboring cell does not include the highest network mode, the terminal device will perform invalid measurement, which causes large power consumption of the terminal device.

[0225] In the embodiment of the present application, when the terminal device detects that the terminal device is not in the highest network mode supported by the terminal device and the multiple cells to be measured do not support the highest network mode, the terminal device can perform cell measurement according to the network mode in the target measurement strategy, which is not the highest network mode. In this way, the terminal device does not need to perform cell measurement in the highest network mode supported by the terminal device, thereby reducing the power consumption of the terminal device.

[0226] Optionally, after step 507, step 508 can also be performed.

[0227] 508. When the measurement result of the target cell meets the cell switching condition, the first cell currently camped by the terminal device is switched to the target cell.

[0228] The target cell is one of the multiple cells to be measured.

[0229] Optionally, in order to update the target measurement strategy, the present application can also perform fitting according to the measurement result and the learning result of the pre-stored historical data. If the fitting degree of the fitting result is good, the target measurement strategy can be optimized. It should be understood that one or more parameters in the target measurement strategy can be adjusted in the optimization process. If the fitting degree of the fitting result is poor (such as completely not fitting), the target measurement strategy is deleted.

[0230] By implementing the embodiment of the present application, the present application can learn the measurement strategy corresponding to the fixed place in advance. In this way, if the terminal device is in the fixed place and the signal strength of the currently camped cell meets the preset triggering condition, the terminal device can perform cell measurement according to the learned target measurement strategy. This can effectively avoid invalid measurement and reduce the power consumption of the terminal device.

[0231]

Technical scheme of cell measurement

[0232] In some embodiments, the user can start the intelligent network selection function in the manner shown in FIG. 10B , FIG. 10D or FIG. 10E , and then the terminal device performs the cell measurement method in the present application. In other embodiments, the terminal device can also automatically perform the cell measurement method shown in the embodiment of the present application. In other embodiments, when the terminal device detects that the network signal quality is poor, the user can be prompted whether to perform the cell measurement method shown in the embodiment of the present application.

[0233] As shown in FIG. 6 , it is a flowchart of the cell measurement method in the embodiment of the present application. The method is applied to a terminal device and specifically includes the following steps:

[0234] 601. Detect whether the terminal device is in a fixed place or a fixed route.

[0235] The specific content can be referred to step 401, which will not be repeated here.

[0236] 602、When the terminal device is on a fixed route, a target measurement strategy is acquired from a preset measurement strategy according to the fixed route and a first cell in which the terminal device currently resides.

[0237] If the terminal device is on a fixed route, the terminal device can acquire a target measurement strategy from a preset measurement strategy according to the fixed route and a first cell in which the terminal device currently resides.

[0238] The specific content of the target measurement strategy can be referred to step 502, which will not be repeated here.

[0239] 603、It is judged whether the first cell in which the terminal device currently resides is included in the plurality of cells that need to be measured.

[0240] In the case where the first cell is not included in the plurality of cells that need to be measured, steps 604 to 606 are executed;

[0241] In the case where the first cell is included in the plurality of cells that need to be measured, steps 605 and 606 are executed.

[0242] 604、The first cell is switched to one of the cells included in the plurality of cells that need to be measured.

[0243] The specific content can be referred to step 504, which will not be repeated here.

[0244] 605、The signal strength of the first cell in which the terminal device currently resides is acquired.

[0245] The specific content can be referred to step 505, which will not be repeated here.

[0246] 606、It is judged whether the signal strength meets a preset trigger condition.

[0247] In the embodiments of the present application, the preset trigger condition includes but is not limited to any one of the following:

[0248] (1) The preset trigger condition includes: the signal strength is less than or equal to a first threshold.

[0249] (2) The preset trigger condition includes: the signal strength is less than or equal to a first threshold, and the signal strength is greater than or equal to a second threshold; the first threshold is greater than the second threshold.

[0250] The first threshold and the second threshold are set according to an empirical value, which can be adjusted according to the actual needs of users, and are not specifically limited in the embodiments of the present application.

[0251] In the case where the signal strength of the first cell meets the preset trigger condition, step 607 is executed;

[0252] In the case that the signal strength of the first cell does not satisfy the preset triggering condition, the third cell measurement is performed. In some embodiments, the third cell is all the neighboring cells of the currently camped cell, that is, the third cell is the cell that needs to be measured as specified in the existing standard. In other embodiments, the third cell is all the neighboring cells of the currently camped cell except the second cell. In this way, when the second cell does not satisfy the cell handover condition, the terminal device can expand the search range.

[0253] 607. Perform cell measurement according to the cell information of the multiple cells that need to be measured to obtain measurement results.

[0254] The specific process can refer to step 507, which will not be repeated here.

[0255] Optionally, after step 607, step 608 can also be performed.

[0256] 608. When the measurement result of the first target cell satisfies the cell handover condition, hand over the first cell currently camped by the terminal device to the target cell.

[0257] The target cell is one of the multiple cells that need to be measured.

[0258] Optionally, in order to update the target measurement strategy, the application can also perform fitting according to the measurement result and the learning result of the pre-stored historical data. If the fitting degree of the fitting result is good, the target measurement strategy can be optimized. It should be understood that one or more parameters in the target measurement strategy can be adjusted during the optimization process. If the fitting degree of the fitting result is poor (such as completely not fitting), the target measurement strategy is deleted.

[0259] By implementing the embodiments of the application, the application can learn the measurement strategy corresponding to the fixed route in advance. In this way, if the terminal device is on the fixed route and the signal strength of the currently camped cell satisfies the preset triggering condition, the cell measurement can be performed according to the learned target measurement strategy. Invalid measurement can be effectively avoided, and the power consumption of the terminal device is reduced.

[0260]

Technical scheme of network search

[0261] In the prior art, when the terminal device is in the case of no network signal coverage, it will still search for a network. This network search will consume a lot of power consumption and is meaningless. Through the technical solution of the embodiment, the range of the network-free area can be learned in advance. When it is detected that the terminal device enters the area, the network search can be stopped, thereby saving power consumption.

[0262] In some embodiments, the user can set the range of the network-free area through the terminal device.FIG. 10B 、 FIG. 10D or FIG. 10E the intelligent network selection function in the manner shown in the figure, and then the terminal device executes the network search method in the present application. In other embodiments, the terminal device can also automatically execute the network search method shown in the embodiments of the present application. In other embodiments, when the terminal device detects that there is no network signal, the user can be prompted whether to execute the network search method shown in the embodiments of the present application.

[0263] As FIG. 7 shown, it is a schematic diagram of one embodiment of the network search method in the embodiments of the present application, which is applied to a terminal device and can specifically include the following steps:

[0264] 701, detecting whether the terminal device is in a fixed place or a fixed route.

[0265] In the embodiments of the present application, the terminal device can detect whether the terminal device is in a fixed place or a fixed route in the case of no network service state. Wherein, it can include but not limited to the following ways to determine whether the terminal device is in a no network service state:

[0266] In one possible implementation manner, FIG. 3 the connection manager in the above-mentioned connection manager detects that the current network state of the terminal device is in a no network service state, and sends a first state message to the modem, which is used to indicate that the current network state of the terminal device is in a no network service state. Or, the connection manager detects that the current network state of the terminal device is in a network service state, and sends a second state message to the modem, which is used to indicate that the current network state of the terminal device is in a network service state. In this way, the modem can determine the current network state of the terminal device according to the type of the state information.

[0267] In another possible implementation manner, the connection manager detects that the current network state of the terminal device is in a no network service state, and sends a state message to the modem. In this way, when the modem receives the state message, it is determined that the current network state of the terminal device is in a no network service state, or when the modem does not receive the state message, it is determined that the current network state of the terminal device is in a network service state.

[0268] For example, the network service state can be a state of connecting with mobile data, a state of connecting with WiFi, a state of connecting with Ethernet or a state of connecting with Bluetooth, etc.; the no network service state can be a state of no service cell, a state of limited service, a state of random access failure, etc., and the specific form of the network service state is not specially limited in the embodiments of the present application.

[0269] It can be understood that the fixed place or the fixed route is related to the behavior of the user. For example, the fixed place is a place where the user frequently moves, such as a home, an office, and the like; and the fixed route is a route frequently walked by the user, such as a route walked by the user to and from work. The specific method of detection can refer to step 401, and will not be described here again.

[0270] 702、When the terminal device is in the fixed place, obtaining a target network searching strategy from the preset network searching strategy.

[0271] In an optional solution, the terminal device obtains the target network searching strategy from the preset network searching strategy according to the fixed place and a cell last camped by the terminal device before the terminal device is dropped.

[0272] The target network searching strategy can be generated by a first processor and then sent to a second processor, and the second processor is configured to execute the target network searching strategy. The first processor and the second processor can be the same processor or different processors.

[0273] The target network searching strategy can include at least one of cell information corresponding to a plurality of cells to be searched; the cell information corresponding to the plurality of cells to be searched includes at least one of frequency corresponding to the plurality of cells to be searched and cell identification corresponding to the plurality of cells to be searched. Of course, the target network searching strategy can also include at least one of search priority of the plurality of cells to be searched, search interval, trigger network searching duration, and network type.

[0274] It should be understood that the trigger network searching duration is used to determine a network searching time; the network searching time can be a time determined according to the time when the terminal device is detected to be dropped and the trigger network searching duration, such as adding the time when the terminal device is detected to be dropped and the trigger network searching duration to obtain the network searching time.

[0275] 703、According to the cell information corresponding to the plurality of cells to be searched, performing network searching to obtain a searching result.

[0276] In the embodiments of the present application, the way of pre-acquiring the plurality of cells to be searched can be various.

[0277] In an embodiment, the plurality of cells to be searched can be: a cell in which the terminal device camps for a longer time or a cell in which the terminal device camps more frequently when the terminal device is in the fixed place, or a cell with better quality of service, or a cell in which the terminal device searches more successfully.

[0278] In another embodiment, the plurality of cells to be searched can be: the first N cells in which the terminal device camps for a longer time when the terminal device is in the fixed place, or the first N cells in which the terminal device camps more frequently, or the first N cells in which the terminal device searches more successfully. N can be a pre-set value.

[0279] If the cell information comprises the cell identifier, the terminal device can determine the cell according to the cell identifier, and then perform cell search on the cell to obtain the search result.

[0280] If the cell information comprises the frequency, the terminal device can perform cell search according to the frequency to obtain the search result.

[0281] If the cell information comprises the cell identifier and the search priority, the terminal device can determine a plurality of cells according to the cell identifier, and then perform cell search on the plurality of cells in descending order of the search priority to obtain the search result.

[0282] If the cell information comprises the cell identifier and the network search trigger time, the terminal device can determine the cell according to the cell identifier, and then perform cell search on the cell at the network search time to obtain the search result.

[0283] If the cell information comprises the cell identifier and the search interval, the terminal device can determine the cell according to the cell identifier, and then perform cell search on the cell according to the search interval to obtain the search result.

[0284] If the cell information comprises the cell identifier, the search interval and the network search trigger time, after detecting that the terminal device is disconnected from the network, the terminal device performs network search on the historical frequency points according to the search interval, and if the network search is not successful for several times, the terminal device terminates the network search according to the search interval and the historical frequency points, and starts to perform network search according to the target network search strategy at the network search time. Or, if there is a successful search in the process of several searches, the terminal device can camp on the searched service cell. Since the service cell can be searched before the network search time, the target network search strategy is biased. At this time, the target network search strategy can be updated. For example, the frequency used for the successful search and the cell identifier of the searched service cell can be used as new learning data, so that deep learning can be performed according to the new learning data, and the target network search strategy can be updated.

[0285] Optionally, in step 703, step 704 can also be performed.

[0286] 704、When it is determined according to the search result that the target cell meets the preset camping condition, the terminal device is camped on the target cell.

[0287] Optionally, the target network search strategy can also be optimized according to the search result. It should be understood that one or more parameters in the target network search strategy can be adjusted in the optimization process.

[0288] Optionally, if the target network search strategy is not successful for several times, the target network search strategy can be deleted.

[0289] Through the embodiments of the present application, the terminal device can learn the network search strategy corresponding to the fixed place in advance. Thus, if the terminal device is in the fixed place and network drop occurs, the terminal device can perform network search according to the learned target network search strategy. Invalid network search can be effectively avoided, and the power consumption of the terminal device is reduced.

[0290] The technical solutions of network search

[0291] In some embodiments, the user can start the intelligent network selection function in the manner shown in FIG. 10B , FIG. 10D or FIG. 10E , and then the terminal device performs the network search method of the present application. In other embodiments, the terminal device can also automatically perform the network search method shown in the embodiments of the present application. In other embodiments, when the terminal device detects that there is no network signal, the user can be prompted whether to perform the network search method shown in the embodiments of the present application.

[0292] As shown in FIG. 8 , it is a schematic diagram of one embodiment of the network search method in the embodiments of the present application, which is applied to a terminal device and can specifically include the following steps:

[0293] 801, detecting whether the terminal device is in a fixed place or a fixed route.

[0294] The specific content can be referred to step 701, which will not be repeated here.

[0295] 802, when the terminal device is in a fixed route, obtaining a target network search strategy from a preset network search strategy according to the fixed route and the last camped cell before the terminal device drops the network.

[0296] The specific content of the target network search strategy can be referred to step 702, which will not be repeated here.

[0297] 803, performing network search according to the cell information corresponding to the multiple cells to be searched to obtain a search result.

[0298] The specific process can be referred to step 703, which will not be repeated here.

[0299] Optionally, after step 803, step 804 can also be performed.

[0300] 804, when it is determined that the target cell meets the preset camped condition according to the search result, camping the terminal device to the target cell.

[0301] Optionally, the present application can also optimize the target network search strategy according to the search result. It should be understood that one or more parameters in the target network search strategy can be adjusted in the optimization process.

[0302] Optionally, if the target network search strategy is not searched successfully for multiple times, the target network search strategy can be deleted.

[0303] Through the embodiments of the present application, the target network search strategy corresponding to the fixed route can be learned in advance. In this way, if the terminal device is in the fixed route and network drop occurs, the terminal device can search for the network according to the learned target network search strategy. Invalid network search can be effectively avoided, and the power consumption of the terminal device is reduced.

[0304] In the embodiments shown in the above FIG. 5 , FIG. 6 , FIG. 7 and FIG. 8 , the preset measurement strategy and the preset network search strategy are involved, and FIG. 4 the embodiment shown in the embodiment involves a target measurement strategy. It should be understood that the target measurement strategy is a certain preset measurement strategy. Therefore, the strategies can be learned in advance through the embodiments of the present application. For ease of description, the preset measurement strategy and the preset network search strategy are collectively referred to as a preset network selection strategy.

[0305] The strategy generation method in the present application can be applied to a terminal device, which can include a smart network selection master module, a modem network selection module, and a sensor hub. It can be understood that the smart network selection master module corresponds to the first processor in the present application, and the modem network selection module corresponds to the second processor in the present application. The preset network selection strategy can be generated by the first processor and sent to the second processor, and the second processor is used to execute the preset network selection strategy. The first processor and the second processor can be the same processor or different processors.

[0306] It can be understood that the present application can include but is not limited to the following ways to trigger the execution of the strategy generation method in the embodiments of the present application:

[0307] Method one, the main setting interface of the terminal device includes a smart network selection function. In this way, after the terminal device receives the start instruction of the smart network selection function, the steps of the strategy generation method in the present application are executed.

[0308] For example, as shown in FIG. 10A , the main setting interface of the terminal device is pre-set with switch controls corresponding to different functions, so that different functions can be set according to the switch controls. For example, FIG. 10A the switch control of the flight mode in is set to the closed state, the switch control of the Bluetooth is set to the open state, and the switch control of the smart network selection is set to the closed state.

[0309] At this time, as shown in FIG. 10BAs shown, users can trigger the smart network selection switch to change the smart network selection switch from the off state to the on state, thereby enabling the smart network selection function of the terminal device.

[0310] It should be noted that this intelligent network selection function can also be set in the battery settings interface. For example, as... FIG. 10C As shown, the intelligent network selection function is available in power-saving mode. Furthermore, when power-saving mode is enabled, the terminal device displays the on / off control for this intelligent network selection. Thus, as... FIG. 10D As shown, users can trigger the smart network selection switch to change the smart network selection switch from the off state to the on state, thereby enabling the smart network selection function of the terminal device.

[0311] Method 2: The terminal device automatically executes the strategy generation method in the embodiments of this application after startup.

[0312] Method 3: When the terminal device detects high power consumption, it executes the strategy generation method in this application embodiment.

[0313] Method 4: When the terminal device detects high power consumption, a prompt box is displayed so that the user can determine whether to enable the intelligent network selection function.

[0314] For example, such as FIG. 10E As shown, due to the high power consumption of the terminal device, a prompt box is displayed, which includes the text "Enable intelligent network selection function?", a "Yes" button, and a "No" button. Thus, when the user triggers the "Yes" button, the terminal device executes the strategy generation method in this embodiment.

[0315] The above-described method for triggering the strategy generation method in this application embodiment is merely illustrative and not intended to limit the scope of the application. After determining the strategy generation method through the above method, strategy generation can be performed through the following steps:

[0316] 901. The environmental perception unit acquires descriptive information, network event information, and sensor information at different times within a specified time period.

[0317] The description information can include at least one of a WiFi name to which the terminal device is connected, an identity of a serving cell in which the terminal device resides, a signal strength of the serving cell, an identity of a neighbor cell of the serving cell and a signal strength of the neighbor cell, a WiFi signal strength to which the terminal device is connected, names of other WiFi that can be scanned when connected to the WiFi, and a signal strength of the other WiFi. Of course, the description information can also include other information, such as at least one of a network standard corresponding to the serving cell, a location area (LA) corresponding to the serving cell, a signal quality value corresponding to the serving cell, and a discontinuous reception (DRX) cycle, a network standard corresponding to the neighbor cell, and a signal quality corresponding to the neighbor cell. It should be understood that the neighbor cell can be a single cell or multiple cells.

[0318] It can be understood that the description information can be obtained in the following manner, but is not limited thereto:

[0319] Manner one, the environment perception unit can send a first information acquisition instruction to the modem network selection module before a specified time period arrives; the modem network selection module acquires description information and network event information at different times within the specified time period according to the first information acquisition instruction at a preset period, and sends the description information and the network event information to the environment perception unit.

[0320] Manner two, the modem network selection module has a specified time period stored in advance, and acquires description information and network event information at different times within the specified time period at a preset period when the specified time period arrives, and sends the description information and the network event information to the environment perception unit. As shown in FIG. 9B, this step can include step 9011: the modem network selection module sends the description information and the network event information to the environment perception unit. FIG. 9

[0321] It can be understood that in the above two manners, the modem network selection module can send the description information and the network event information at each time to the environment perception unit after acquiring the description information and the network event information at each time within the specified time period. Alternatively, the modem network selection module can send the description information and the network event information at a certain time to the environment perception unit after acquiring the description information and the network event information at the certain time within the specified time period.

[0322] ​It should be understood that the event information includes a current connection state of the terminal device. For example, the event information includes a network service state and a no network service state. The network service state can be further divided into an idle state and a connected state, and the no network service state can be further divided into a no service state, a limited service state, and a random access failure state (i.e., no free radio resource is allocated to the terminal device by the base station), which are only examples and are not limited in the present application.

[0323] Similarly, the manner of acquiring the sensor information can include but is not limited to the following manners:

[0324] Manner one: the environment perception unit can send a second information acquisition instruction to the sensor processor before the specified time period arrives; the sensor processor acquires sensor information at different times according to the second information acquisition instruction at a preset period, and sends the sensor information to the environment perception unit.

[0325] Manner two: the sensor processor pre-stores the specified time period, and acquires sensor information at different times according to a preset period when the specified time period arrives, and sends the sensor information to the environment perception unit.

[0326] It can be understood that in the above two manners, the sensor processor can send the sensor information at each time to the environment perception unit after acquiring the sensor information at each time. Alternatively, the sensor processor can send the sensor information at a certain time to the environment perception unit after acquiring the sensor information at the certain time. As shown in the following table, the sensor processor can send the sensor information at each time to the environment perception unit after acquiring the sensor information at each time. FIG. 9 It should be understood that the sensor information can include the position feature data in the present application.

[0327] The sensor information can be data collected by an environment perception sensor built in the terminal device, and the environment perception sensor can include but is not limited to at least one of the following: a gravimeter sensor, an acceleration sensor, a gyroscope sensor, etc. Of course, the environment perception sensor in the present application can also include other sensors, for example, it also includes a global positioning system (GPS) sensor, so that the information of the GPS positioning point can be acquired through the GPS sensor.

[0328] It should be understood that the specified time period can be a time period pre-set by the user. For example, the user usually works in the office between 9:30 and 11:30, rests at home between 20:30 and 21:30, etc., so the specified time period can be set to 9:30-11:30 and 20:30-21:30.

[0329] For example, as shown in FIG. 7A, after the user opens the switch control of the intelligent network selection, the terminal device displays the intelligent network selection interface. For example, as shown in FIG. 7B, the intelligent network selection interface is used to set a time period. The terminal device has stored a specified time period 9:30-11:30. FIG. 11A

[0330] At this time, as shown in FIG. 7C, the user can trigger the "+" control to add a new specified time period. FIG. 11B

[0331] After the user triggers the "+" control, the interface of the terminal device is as shown in FIG. 7D. At this time, if the user triggers the rectangular box in which "from 20:30" is located, the starting time of the specified time period can be determined in the hour list and the minute list displayed on the display screen of the terminal device. FIG. 11C

[0332] If the user sets the specified time period, the intelligent network selection interface can be returned, as shown in FIG. 7E. The set time period includes the originally stored specified time period 9:30-11:30 and the newly added specified time period 20:30-21:30. FIG. 11D

[0333] The above-described manner of setting the specified time period is only illustrative, and the present application does not make a specific limitation in this regard.

[0334] 902、The environment sensing unit determines whether the terminal device is in a fixed place or a fixed route according to sensor information at different times.

[0335] In some embodiments, there is a difference between the location characteristics of the fixed place and the fixed route, so that the terminal device can be identified to be in the fixed place or the fixed route through the sensor information. For example, the location characteristics fluctuate greatly, and the user is on the fixed route; the location characteristics fluctuate slightly, and the user is in the fixed place.

[0336] In other embodiments, the terminal device can observe the information of the GPS positioning point collected by the GPS sensor in the specified time period. If the GPS positioning point is in a state of not moving for a long time, it can be determined that the terminal device is in the fixed place; on the contrary, if the GPS positioning point is in a state of constantly moving, it can be determined that the terminal device is in the fixed route.

[0337] In other embodiments, the present application can also determine whether the terminal device is in the fixed route or the fixed place according to the description information at different times. For example, assuming that the description information includes the cell identifier of the current cell in which the terminal device resides, if the cell in which the terminal device resides in a time period is the same cell, it can be determined that the place in which the terminal device is in the time period is the fixed place.

[0338] ​​​​For example, if the description information includes the cell identifier of the current cell in which the terminal device is located, and if the terminal device stays in a small number of cells within the specified time period and stays in each cell for a long time, it can be determined that the terminal device stays in a fixed place within the specified time period. If the terminal device stays in a large number of cells within the specified time period and stays in each cell for a short time, it can be determined that the terminal device stays in a fixed route within the specified time period.

[0339] For example, if the description information includes the WiFi identifier of the current WiFi to which the terminal device is connected, and if the terminal device connects to a small number of WiFi within the specified time period and connects to each WiFi for a long time, it can be determined that the terminal device stays in a fixed place within the specified time period. If the terminal device connects to a large number of WiFi within the specified time period and connects to each WiFi for a short time, it can be determined that the terminal device stays in a fixed route within the specified time period.

[0340] In some embodiments, if the user has pre-set at least one of a fixed place and a fixed route in the positioning map of the terminal, the terminal device can read the setting information of the positioning map and determine the specific fixed place or the specific fixed route according to the setting information.

[0341] The above-described method of determining whether the terminal device stays in a fixed place or a fixed route is only illustrative, and the present application does not make specific limitations thereto.

[0342] 903、The environment sensing unit sends one of the route identifier of the fixed route in which the terminal device is located or the place identifier of the fixed place in which the terminal device is located, the description information, and the network event information to the memory.

[0343] It can be understood that the memory can store a plurality of sets of data, and each set of data includes one of the route identifier of the fixed route in which the terminal device is located or the place identifier of the fixed place in which the terminal device is located, the description information, and the network event information corresponding to the terminal device at a certain time.

[0344] It should be understood that the memory can associate each set of data to a corresponding fixed place or fixed route.

[0345] 904、The network selection strategy interaction unit obtains the plurality of sets of data stored in the memory, and generates a preset network selection strategy and a strategy triggering condition of the preset network selection strategy according to the plurality of sets of data.

[0346] It can be understood that if the application generates a network selection strategy for a fixed route or a fixed place, the step can obtain the multiple sets of data associated with the fixed route or the fixed place from the memory.

[0347] The application describes the measurement trigger condition as follows:

[0348] Case one, when the network event information includes a no-network service state, the strategy trigger condition includes that the terminal device is in a fixed route or a fixed place, it is determined that the terminal device is out of network, and the last camped cell of the terminal device before it is out of network is the same as the out-of-network cell associated with the preset network search strategy in the learning result.

[0349] Case two, when the terminal device is in a network service state, the strategy trigger condition includes that the terminal device is in a fixed route or a fixed place, and the current cell camped by the terminal device is the same as the cell associated with the preset measurement strategy in the learning result.

[0350] It should be noted that the detailed content of the preset network selection strategy can refer to the target measurement strategy and the target network search strategy described in FIG. 4 、 FIG. 5 、 FIG. 6 、 FIG. 7 and FIG. 8 , which will not be described here.

[0351] By implementing the embodiments of the application, the strategy trigger condition and the preset network selection strategy can be determined in advance for at least one of the fixed place and the fixed route, so that the terminal device can perform network selection processing according to the preset network selection strategy when the strategy trigger condition is met. In this way, the network selection processing by the preset network selection strategy can effectively reduce the loss of the terminal device and improve the network selection efficiency.

[0352] As shown in FIG. 12 , the embodiments of the application generally describe a network selection method, in some embodiments, a user can start the intelligent network selection function in the manner shown in FIG. 10B 、 FIG. 10D or FIG. 10E , and then the terminal device executes the network selection method in the application. In other embodiments, the terminal device can also automatically execute the network selection method shown in the embodiments of the application. In other embodiments, when the terminal device detects that the network signal quality is poor, it can prompt the user whether to execute the network selection method shown in the embodiments of the application. The embodiments of the application do not limit the starting mode of the network selection.

[0353] The network selection method in the application can be applied to a terminal device, and the method can be used after step 904 in FIG. 9 , including the following steps:

[0354] 1201、The environment sensing unit acquires target information at different time instants in a recent time period; the target information comprises sensor information, description information and network event information.

[0355] In an optional embodiment, if the terminal device is in a network service state, the terminal device is in a network service state, the terminal device is in a network service state, and the terminal device is in a network service state.

[0356] In the embodiments of the present application, the acquisition process of the sensor information, the description information and the network event information can refer to step 901, which will not be repeated here.

[0357] 1202、The environment sensing unit sends a place identifier of a fixed place or a route identifier of a fixed route to the network selection strategy interaction unit when it is determined according to the target information that the terminal device is in a fixed route or a fixed place.

[0358] There are various ways to determine whether the terminal device is in a fixed place or a fixed route, such as the method of detecting whether the terminal device is in a fixed place or a fixed route in step 401, which will not be repeated here.

[0359] 1203、The network selection strategy interaction unit acquires current cell information and current event information of the terminal device.

[0360] It can be understood that the information type of the current event information is the same as that of the network event information in step 901, and the present application will not be repeated here.

[0361] It should be understood that, in the case that the terminal device is in a network service state, the current cell information comprises cell information of the last cell in which the terminal device camps before it is out of network; in the case that the terminal device is in a network service state, the current cell information comprises cell information of the current cell in which the terminal device camps. The cell information can comprise at least one of a cell identifier, a signal strength, a signal quality value and a frequency.

[0362] The method of acquiring the current cell information and the current event information of the terminal device can refer to step 901, which will not be repeated here.

[0363] 1204、The network selection strategy interaction unit determines whether the terminal device satisfies a strategy triggering condition according to one of the place identifier and the route identifier, the current cell information and the current event information.

[0364] The present application can pre-store a preset network selection strategy and a strategy triggering condition in the network selection strategy interaction unit. The specific content of the strategy triggering condition can refer to step 904, which will not be repeated here.

[0365] When it is determined that the terminal device meets the policy triggering condition, step 1205 is performed.

[0366] When it is determined that the terminal device does not meet the policy triggering condition, step 1201 is returned to.

[0367] 1205、The network selection policy interaction unit acquires a target network selection policy.

[0368] The preset network selection policy and the policy triggering condition have a corresponding relationship. Therefore, the target network selection policy corresponding to the policy triggering condition currently met by the terminal device can be acquired in this step.

[0369] The detailed content of the target network selection policy can refer to the target measurement policy described in the embodiments shown in FIG. 4 , FIG. 5 and FIG. 6 the target network search policy described in the embodiments shown in FIG. 7 and FIG. 8 , and will not be described here.

[0370] 1206、The network selection policy interaction unit sends the target network selection policy to the modem network selection module.

[0371] 1207、The modem network selection module performs network selection processing according to the target network selection policy to obtain a processing result.

[0372] The network selection processing process can refer to the embodiments shown in FIG. 4 , FIG. 5 and FIG. 6 , and FIG. 7 and FIG. 8 , and will not be described here.

[0373] Optionally, after step 1207, step 1208 can also be included.

[0374] 1208、The modem network selection module sends the processing result to the network selection policy interaction unit.

[0375] The processing result includes the measurement result described in the embodiments shown in FIG. 5 or FIG. 6 , or the search result described in the embodiments shown in FIG. 7 or FIG. 8 .

[0376] 1209、The network selection policy interaction unit determines whether to update the target network selection policy or delete the target network selection policy according to the processing result.

[0377] If the target network selection policy is updated, step 1210 is performed;

[0378] If the target network selection strategy is deleted, proceed to step 1211.

[0379] 1210. Update the target network selection strategy.

[0380] It should be understood that one or more parameters in the target network selection strategy can be adjusted during the update process.

[0381] 1211. The network selection strategy interaction unit sends a deletion command to the modem network selection module.

[0382] The deletion command is used to instruct the deletion of the target network selection strategy.

[0383] 1212. The modem network selection module deletes the target network selection policy according to the deletion command.

[0384] It should be noted that the network selection policy interaction unit needs to delete the stored target network selection policy. After the modem network selection module deletes the target network selection policy, it needs to perform a network search based on historical frequency points, or perform cell measurement based on the current cell's neighboring cells.

[0385] By implementing this embodiment, the intelligent network selection master control module can learn network selection strategies and triggering conditions corresponding to different fixed routes or locations based on historical information. Then, when the terminal device meets the triggering conditions, the intelligent network selection master control module can send the network selection strategy to the modem network selection module, so that the modem network selection module can perform network selection processing. This increases the interaction between the intelligent network selection master control module and the modem network selection module, enabling the modem network selection module to perform targeted network selection processing based on the preset network selection strategy in the network search strategy interaction unit, thereby reducing terminal power consumption.
