Background

With the development of mobile communication technology, cellular networks have more and more network standards, such as 2G network standard, 3G network standard, 4G network standard and 5G network standard.

In the current network searching strategy, the terminal device usually selects one or more network standards as the target network standard. When the terminal equipment is in the cellular network with the non-target network type, the terminal equipment can continuously search the cellular network cell with the target network type.

However, the continuous search for the cellular network cell of the target network system may generate higher measurement power consumption, which affects the endurance time of the terminal device.

The embodiment of the application provides a network measurement method, a network measurement device, a terminal device and a computer readable storage medium, which can solve the problems that the measurement power consumption of the current network measurement scheme is high and the endurance time of the terminal device is influenced.

A first aspect of an embodiment of the present application provides a network measurement method, including:

when the first position information of the terminal equipment meets a preset trigger condition, acquiring cell information of a cellular network cell connected with the terminal equipment;

and inquiring a search strategy corresponding to the cell information, and executing corresponding network measurement operation according to the search strategy.

It should be noted that a preset trigger condition may be set on the terminal device, and when the preset trigger condition is satisfied, the terminal device obtains cell information of a currently connected cellular network cell, and executes subsequent steps.

The content of the cell information can be set according to actual conditions. For example, the cell information may include a cell identifier and a cell frequency point.

The terminal equipment can acquire the cell information of the currently connected cellular network cell and inquire a corresponding search strategy according to the cell information.

After the search strategy is determined, the terminal device can execute corresponding network measurement operation according to the search strategy, search the cellular network cell of the target network type in a targeted manner, improve the search efficiency and save the measurement power consumption.

In a possible implementation manner of the first aspect, the obtaining cell information of a cellular network cell connected to a terminal device includes:

acquiring first position information of the terminal equipment;

and if the first position information is in the target area, acquiring cell information of a cellular network cell connected with the terminal equipment.

It should be noted that the content of the preset trigger condition may be set according to actual situations. For example, the preset trigger condition may be that the terminal device is in the target area.

At this time, the terminal device may acquire the first position information. The first position information is position information of a current position of the terminal equipment.

When the terminal device detects that the first position information is in the target area, the terminal device is in the target area and meets a preset trigger condition, the terminal device can acquire cell information of a currently connected cellular network cell, inquire a corresponding search strategy according to the cell information, and execute corresponding network measurement operation according to the search strategy.

The preset trigger condition is set to be that the terminal equipment is located in the target area, so that the terminal equipment can search the cellular network cell of the target network system in the target area according to the search strategy, the search efficiency is improved, the measurement power consumption is saved, the endurance time of the terminal equipment is prolonged, and the use experience of the user in using the terminal equipment in the target area is improved.

In another possible implementation manner of the first aspect, the obtaining cell information of a cell of a cellular network connected to a terminal device includes:

acquiring first position information of the terminal equipment;

and if the first position information is on the target path, acquiring cell information of a cellular network cell connected with the terminal equipment.

It should be noted that the preset trigger condition may also be that the terminal device is on the target path.

The terminal device may acquire the first location information. The first position information is position information of a current position of the terminal equipment.

When the terminal device detects that the first position information is on the target path, the terminal device is on the target path and meets a preset trigger condition, the terminal device can acquire cell information of a currently connected cellular network cell, inquire a corresponding search strategy according to the cell information, and execute corresponding network measurement operation according to the search strategy.

The preset trigger condition is set to be that the terminal equipment is located on the target path, so that the terminal equipment can search the cellular network cell of the target network type on the target path according to the search strategy in a targeted mode, the search efficiency is improved, the measurement power consumption is saved, the endurance time of the terminal equipment is prolonged, and the use experience of a user for using the terminal equipment on the target path is improved.

In a possible implementation manner of the first aspect, the performing, according to the search policy, a corresponding network measurement operation includes:

acquiring a target network system identifier in the search strategy;

and if the target network type identifier is a first identifier, executing corresponding network measurement operation according to cell information of a target cell in the search strategy, wherein the first identifier is used for indicating that a cellular network cell with the target network type exists, and the network state of the cellular network cell with the target network type meets the condition of a preset threshold value.

It should be noted that after the search policy is determined, the target network format identifier in the search policy may be obtained.

And the target network type identifier in the search strategy is used for identifying whether the cellular network cell with the target network type exists in the adjacent cells of the cellular network cell. The target network type may be the highest network type of the terminal device, for example, for a mobile phone with the highest network type of 5G, the target network type of the mobile phone may be the 5G network type; or, the target network type may also be a network type higher than the current network type of the terminal device, for example, for a mobile phone with a highest network type of 5G, if the mobile phone is currently in a 3G network type, the target network type may be a 4G network type or a 5G network type, and if the mobile phone is currently in a 4G network type, the target network type may be a 5G network type.

If the target network type identifier is the first identifier, the cellular network cell of the target network type exists in the adjacent cells of the cellular network cell currently connected with the terminal equipment, and the network state of the cellular network cell meets the preset threshold value condition.

At this time, the terminal device acquires cell information of the target cell in the search policy. The target cell is a cellular network cell to which the terminal device is to be switched, and may be a cellular network cell of a target network system, or may be a cellular network cell of a non-target network system (for example, a 4G cell of a 5G network system supporting non-independent networking), and the cell information of the target cell is cell information of the target cell.

The content of the cell information of the target cell may be set according to actual conditions. For example, the cell information of the target cell may include a target cell identity and a target cell frequency point.

After the cell information of the target cell is acquired, the terminal device may perform a targeted search according to the cell information of the target cell. Compared with the network measurement operation without pertinence, the network measurement operation is executed according to the cell information of the target cell, the efficiency of searching the target cell can be improved, the speed of connecting the target cell is further improved, useless network measurement operation can be reduced, the measurement power consumption is saved, the endurance time of the terminal equipment is improved, and the use experience of a user is greatly improved.

In another possible implementation manner of the first aspect, the performing, according to the search policy, a corresponding network measurement operation further includes:

and if the target network type identifier is a second identifier, stopping searching the cellular network cell of the target network type, wherein the second identifier is used for indicating that the cellular network cell of the target network type does not exist or the network state of the cellular network cell of the target network type does not meet the condition of a preset threshold value.

It should be noted that, if the target network type identifier is the second identifier, it indicates that there is no cellular network cell of the target network type in the neighboring cells of the cellular network cell to which the terminal device is currently connected, or the network state of the cellular network cell of the target network type does not satisfy the preset threshold condition.

At this time, if the terminal device searches for the cellular network cell of the target network system, it is very likely that the cellular network cell of the target network system cannot be searched, and a large amount of measurement power consumption is consumed.

Therefore, if the target network type identifier is the second identifier, the terminal device can stop searching the cellular network cell of the target network type, so that the measurement power consumption is saved, the endurance time of the terminal device is prolonged, and the use experience of a user is improved.

In another possible implementation manner of the first aspect, the performing the corresponding network measurement operation according to the search policy further includes:

if the target network type identifier is a second identifier, changing a search interval for searching the cellular network cell of the target network type from a first preset time length to a second preset time length, wherein the first preset time length is less than the second preset time length, and the second identifier is used for indicating that the cellular network cell of the target network type does not exist or the network state of the cellular network cell of the target network type does not meet the condition of a preset threshold value.

It should be noted that, when the target network type identifier is the second identifier, the terminal device may stop searching for the cellular network cell of the target network type, or the terminal device may also extend the search interval for searching for the cellular network cell of the target network type.

At this time, the terminal device may change the search interval for searching the cellular network cell of the target network type from the first preset duration to the second preset duration.

The first preset time is a search interval before the terminal equipment is changed, the second preset time is a search interval after the terminal equipment is changed, the first preset time is shorter than the second preset time, and the search interval is changed from the first preset time to the second preset time, so that the search interval of the terminal equipment for searching the cellular network cell of the target network system can be prolonged.

The frequency of the terminal device for searching the cellular network cell of the target network system can be reduced by prolonging the search interval of the terminal device for searching the cellular network cell of the target network system.

Under the same time span, the frequency of searching the cellular network cell of the target network type by the terminal equipment is reduced, so that the times of executing network measurement operation by the terminal equipment can be reduced, the measurement power consumption is saved, the endurance time of the terminal equipment is prolonged, and the use experience of a user is improved.

In a possible implementation manner of the first aspect, before the obtaining the first location information of the terminal device, the method further includes:

performing behavior recognition on the historical position information of the terminal equipment, and determining a strategy cell according to a behavior recognition result;

and determining a search strategy corresponding to the strategy cell according to the historical network measurement result corresponding to the strategy cell, and establishing and storing an association relationship between the cell information of the strategy cell and the search strategy corresponding to the strategy cell.

It should be noted that, when learning the search policy, the terminal device may acquire the historical location information, perform behavior recognition on the historical location information, and obtain a behavior recognition result.

Then, the terminal device may determine the policy cell according to the behavior recognition result. A policy cell refers to a cellular network cell that needs to learn a search policy.

When learning the search strategy of the strategy cell, the terminal device may obtain a historical network measurement result corresponding to the strategy cell.

And through the historical network measurement result, the terminal equipment determines the search strategy corresponding to the strategy cell, establishes the association relation between the cell information of the strategy cell and the search strategy and stores the association relation.

And when the terminal equipment needs to inquire the search strategy subsequently, the corresponding search strategy can be quickly inquired according to the cell information, and the corresponding network measurement operation is executed according to the search strategy, so that the search efficiency is improved, the measurement power consumption is saved, the endurance time of the terminal equipment is prolonged, and the use experience of a user is improved.

In a possible implementation manner of the first aspect, the performing behavior identification on the historical location information of the terminal device, and determining the policy cell according to a result of the behavior identification includes:

performing behavior recognition on historical position information of the terminal equipment to determine a target area;

and determining the cellular network cell of the non-target network type connected by the terminal equipment in the target area as a policy cell.

It should be noted that, when the terminal device performs behavior recognition on the historical location information, it may select and recognize an area where the user often resides for a long time, and determine the area where the user often resides for a long time as the target area. For example, assuming that the user's daily life rules are two-in-one for home and business, the user may often reside at home and business for a long time. The terminal equipment can conduct behavior recognition on the historical position information, recognize that the home and the company are areas where the user often resides for a long time, and determine the home and the company as target areas.

After the target area is determined, the terminal device may determine, as a policy cell, a cellular network cell of a non-target network type to which the terminal device has been connected in the target area, and learn a search policy of the policy cell.

Then, when the user is in the target area, if the terminal device is connected with the cellular network cell of the non-target network type, the terminal device can determine a search strategy according to the cell information of the currently connected cellular network cell, and execute corresponding network measurement operation according to the search strategy, thereby improving the search efficiency, saving the measurement power consumption, prolonging the endurance time of the terminal device, and improving the use experience of the user in the target area when using the terminal device.

In another possible implementation manner of the first aspect, the performing behavior recognition on the historical location information of the terminal device, and determining the policy cell according to a behavior recognition result includes:

performing behavior recognition on historical position information of the terminal equipment to determine a target path;

and determining the cellular network cell of the non-target network type connected on the target path by the terminal equipment as a policy cell.

When the terminal device performs behavior recognition on the historical location information, the terminal device may select and recognize a path that the user frequently walks, and determine the path that the user frequently walks as the target path, in addition to recognizing the target area. For example, assuming that the daily life rule of the user is two points and one line of a home and a company, the path between the home and the company of the user is a path that the user often walks. The terminal equipment can conduct behavior recognition on the historical position information, recognize that a path between the home and the company of the user is a path which the user frequently walks, and determine the path between the home and the company as a target path.

After the target path is determined, the terminal device may determine, as a policy cell, a cellular network cell of a non-target network system to which the terminal device has been connected on the target path, and learn a search policy of the policy cell.

Then, when the user is on the target path, if the terminal device is connected with the cellular network cell of the non-target network type, the terminal device can determine a search strategy according to the cell information of the currently connected cellular network cell, and execute corresponding network measurement operation according to the search strategy, thereby improving the search efficiency, saving the measurement power consumption, prolonging the endurance time of the terminal device, and improving the use experience of the user in using the terminal device on the target path.

and establishing and storing the association relationship between the cell information of the strategy cell and the search strategy in the idle state.

It should be noted that, for a terminal device of a 5G network system supporting non-independent networking, there may be a certain difference between an idle state search policy and a connected state search policy.

In the idle state, the terminal device does not search for the 5G cell, and therefore, the terminal device may obtain a historical network measurement result in the idle state corresponding to the policy cell.

If the historical network measurement result in the idle state comprises a 4G cell of a 5G network system supporting non-independent networking and the network state of the 4G cell meets the preset threshold value condition, determining the 4G cell as a target cell, recording the content of a target network identifier as a first identifier, and recording the target network identifier and the cell information of the target cell in a search strategy in the idle state.

The network measurement method provided by the embodiment of the application can be applied to terminal devices such as a mobile phone, a tablet personal computer, a wearable device, a vehicle-mounted device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, and the embodiment of the application does not limit the specific type of the terminal device at all.

For example, the terminal device may be a Station (ST) in a WLAN, and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a vehicle networking terminal, a computer, a laptop, a handheld communication device, a handheld computing device, a satellite Wireless device, a Wireless modem card and/or other devices for communicating over a Wireless system, and a next generation communication system, such as a Mobile terminal in a 5G Network or a Mobile terminal in a future evolved Public Land Mobile Network (PLMN) Network, and so on.

Some terms used in the embodiments of the present application will be described below.

Cellular networks (Cellular networks), also called mobile networks (mobile networks), are a mobile communication hardware architecture and are divided into analog Cellular networks and digital Cellular networks. The signal coverage of each communication base station forming the network coverage is hexagonal, so that the whole network is named like a honeycomb.

The second generation mobile communication technology (2 th generation mobile networks, 2g) takes digital voice transmission technology as the core.

Third generation mobile communication technology (3G), compared with second generation mobile communication technology (2G), 3G mainly combines wireless communication and internet and other communication technologies comprehensively to form a new mobile communication system.

A main advantage of the fourth generation mobile communication technology (4 th generation mobile networks, 4G) compared to 3G is that a Wireless Local Area Network (WLAN) technology and a 3G communication technology are well combined, so that the transmission speed of an image is faster, and the quality of the transmitted image and the image are more clearly seen.

The fifth generation mobile communication technology (5 th generation mobile networks, 5G) has a data transmission rate far higher than that of 4G cellular networks, and can reach 10Gbit/s at most, which is 100 times faster than that of 4G cellular networks. Another advantage of 5G cellular networks is lower network delay (i.e., faster response time), with 5G cellular networks having network delays below 1 millisecond and 4G cellular networks having network delays of 30-70 milliseconds.

A cell, also called a cellular network cell, refers to an area covered by one or a part of a base station (sector antenna) in a cellular mobile communication system, in which area a mobile station can reliably communicate with the base station via a radio channel.

And the 4G cell supports a cellular network cell of a 4G network system.

And the 5G cell supports a cellular network cell of a 5G network system.

In general, in order to improve the internet experience of a user, a developer of a terminal device usually wants that the terminal device can reside in a cellular network having a network system with the fastest data transmission speed and the smallest network delay as much as possible. For example, after 5G business, developers of 5G handsets want the 5G handsets to reside in 5G cells supporting 5G network systems as much as possible.

Therefore, a developer of the terminal device usually sets the corresponding network standard as a target network standard, where the target network standard may be the highest network standard supported by the terminal device or a network standard higher than the current network standard of the terminal device. When the terminal equipment is in the cellular network with the non-target network type, the terminal equipment can continuously measure the cellular network cell with the target network type.

When the terminal device detects a cellular network cell of a target network system and a network measurement result of the cellular network cell meets a threshold value, the terminal device is switched to the cellular network cell and connected with a cellular network of the target network system.

If the terminal device is in the coverage area of the cellular network cell of the target network type, the network searching mode can enable the terminal device to be connected with the cellular network cell of the target network type. However, if the terminal device is out of the coverage area of the cellular network cell of the target network system, the network search strategy may generate unnecessary measurement power consumption, which affects the endurance time of the terminal device.

Take a specific application scenario as an example. As shown in fig. 1, the circles in fig. 1 represent the coverage of a cell of the cellular network. Suppose that a user resides in a certain location for 8 hours for a long time, the location is within the coverage of the 4G cell 102, the terminal device 101 is connected with the 4G cell 102 outside the coverage of the 5G cell 103, and resides in the 4G cellular network, and the target network system set on the terminal device 101 is the 5G network system.

At this time, since the terminal device 101 is connected to the cellular network cell of the non-target network system, the terminal device 101 searches the 5G cell 103 according to the network measurement configuration information sent by the base station of the 4G cell 102.

However, since the terminal apparatus 101 is out of the coverage of the 5G cell 103, the terminal apparatus 101 cannot search the 5G cell 103 and cannot connect to the 5G cell 103, and the terminal apparatus 101 continues to search the 5G cell 103 for 8 hours in which the user resides, consuming a large amount of useless measurement power consumption.

Alternatively, as shown in fig. 2, the circle in fig. 2 represents the coverage area of the cellular network cell, and the line with an arrow represents the walking path and walking direction of the user. The path may pass through 4G cell 201, 4G cell 202, and 4G cell 203, but the path cannot be covered by 5G cell 204. The target network system of the terminal device 205 is a 5G network system.

When the user walks on the path, the terminal device 205 connects the 4G cell 201, the 4G cell 202, and the 4G cell 203 in this order. However, since none of the 4G cell 201, the 4G cell 202, and the 4G cell 203 is a 5G cell, the terminal apparatus 205 performs a search for a 5G cell based on the network measurement configuration information.

However, since this path is out of the coverage of the 5G cell 204, the terminal device 205 cannot always search for the 5G cell 204 and cannot connect to the 5G cell 204, and the terminal device 205 may continue to search for the 5G cell 204 during the time when the user walks this path, consuming a large amount of useless measurement power consumption.

In summary, the current network search strategy can cause the terminal device to generate higher measurement power consumption, which affects the endurance time of the terminal device.

In view of this, the embodiment of the present application provides a network measurement method, which can solve the problem that the current network search strategy causes higher measurement power consumption of a terminal device, which affects the endurance time of the terminal device.

Next, a network measurement method provided by the present embodiment will be described from the perspective of the terminal device. Please refer to fig. 3 and fig. 10, which show a flow chart of a network measurement method, the method includes:

1. and learning a search strategy.

S301, acquiring history information.

And recording the history information of the terminal equipment in the using process of the terminal equipment. The historical information may include one or more of historical location information of the terminal device, historical network measurement results, cell information of cellular network cells to which the terminal device has been connected, and the like.

The historical position information represents position information of a place where the terminal device resides or moves once, and the historical network measurement result represents a network measurement result obtained by measurement when the terminal device performs network measurement operation in the past.

S302, determining the strategy cell and the search strategy corresponding to the strategy cell according to the historical information, and establishing and storing the association relationship between the cell information of the strategy cell and the search strategy.

After obtaining the history information, the terminal device may determine the policy cell according to the history information, learn the search policy of the policy cell, and establish and store an association relationship between the cell information of the policy cell and the search policy corresponding to the policy cell.

In some embodiments, the policy cell may be a cellular network cell of some area.

The terminal equipment can acquire historical position information, conduct behavior recognition on the historical position information, determine which areas are areas where the user resides for a long time, determine the areas where the user resides for a long time as target areas, and determine the cellular network cells of the non-target network type connected in the target areas by the user as strategy cells.

For example, the terminal device may obtain a preset residence time threshold and a preset residence time threshold, and perform behavior identification on the historical location information of the terminal device according to the preset residence time threshold and the preset residence time threshold.

And if the residence time of the terminal equipment in a certain area is greater than the preset residence time threshold, adding 1 to the residence times. And the terminal equipment determines the area with the residence time greater than or equal to a preset residence time threshold as a target area.

And then, the terminal equipment acquires the cell information of the cellular network cell which is connected in the target area by the terminal equipment, and determines the cellular network cell of the non-target network type which is connected in the target area by the terminal equipment as a strategy cell.

The specific values of the preset residence time threshold and the preset residence time threshold can be set according to actual requirements. For example, the preset stay time threshold may be set to 10 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours, or the like; the preset resident number threshold may be set to 5 times, 10 times, 20 times, 50 times, etc. The specific values of the preset residence time threshold and the preset residence time threshold are not limited in any way in the embodiment of the present application.

In other embodiments, the policy cell may be a cell of a cellular network of some path.

The terminal equipment can acquire historical position information, conduct behavior recognition on the historical position information and determine a path where a user walks.

Then, the terminal device may determine all the identified paths as target paths, or the terminal device may also obtain the number of walks corresponding to each path, and determine paths with the number of walks being greater than or equal to a preset number of walks threshold as target paths.

After the target path is determined, the terminal device may obtain cell information of a cellular network cell that the terminal device has connected to on the target path, and determine a cellular network cell of a non-target network type that the terminal device has connected to on the target path as a policy cell.

The specific value of the preset walking time threshold value can be set according to actual requirements. For example, the preset walking number threshold may be set to 5 times, 10 times, 20 times, 50 times, etc. The specific value of the preset walking time threshold is not limited in any way in the embodiment of the application.

In a handover mechanism of a cellular network cell, after a terminal device establishes a connection with a base station of the cellular network cell, the base station of the cellular network cell sends network measurement configuration information to the terminal device. The network measurement configuration information may include one or more of cell identifier of the measurement cell, measurement frequency, measurement starting condition, measurement result reporting trigger condition, measurement time period, and the like.

After receiving the network measurement configuration information sent by the base station of the cellular network cell, the terminal device switches the communication frequency of the terminal device to the measurement frequency to perform network measurement operation when meeting the measurement starting condition and executing measurement, so as to obtain a network measurement result, and then switches the communication frequency back to the communication frequency of the original cellular network cell. The network measurement operation performed by the terminal device on the measurement frequency may be to search all cells on the measurement frequency, or may also be to search a specific cell on the measurement frequency.

The network measurement result may include cell information of the neighboring cell searched by the terminal device and a network state of the neighboring cell, and the terminal device determines whether to perform a cell handover operation according to the network measurement result.

Therefore, the terminal device may obtain the historical network measurement result corresponding to each policy cell. And determining the cell information and the network state of the neighbor cell of the strategy cell according to the historical network measurement result.

If a cellular network cell of a target network type exists in neighboring cells of a policy cell and the network state of the cellular network cell of the target network type meets a preset threshold condition, the terminal device may record a target network type identifier as a first identifier, record the target network type identifier and cell information of the cellular network cell of the target network type in a search policy, and establish and store an association relationship between the search policy and the cell information of the policy cell.

The first identification is used for indicating that a cellular network cell with a target network standard exists, and the network state of the cellular network cell with the target network standard meets a preset threshold value condition.

If no cellular network cell of the target network system exists in the neighboring cell of the policy cell, or if the cellular network cell of the target network system exists in the neighboring cell of the policy cell but the network state of the cellular network cell of the target network system does not meet the preset threshold condition, the terminal device may record the target network system identifier as a second identifier, record the target network system identifier in the search policy, and establish and store the association relationship between the search policy and the cell information of the policy cell.

The second identifier is used for indicating that no cellular network cell with the target network standard exists or the network state of the cellular network cell with the target network standard does not meet the condition of a preset threshold value.

The neighbor cell is a cellular network cell searched in the network measurement result.

The network state and the preset threshold value condition can be determined according to actual conditions. For example, in some embodiments, the network status may include one or more of signal strength, signal quality, and the like, and the preset threshold condition may be that the signal strength of the cellular network cell of the target network format is greater than a preset strength threshold and/or the signal quality is greater than a preset quality threshold.

The target network type identifier is used for identifying whether a cellular network cell of the target network type exists in the neighbor cells of the policy cell. The target network identification may include a first identification and a second identification. The expression form of the target network identifier may be set according to an actual situation, for example, the terminal device may use 1 to represent the first identifier and 0 to represent the second identifier, and when the value of the target network identifier is 0, it represents that there is no cellular network cell of the target network type; and when the value of the target network identifier is 1, indicating that the cellular network cell with the target network type exists.

The cell information may be determined according to actual conditions. For example, in some embodiments, the cell information may include a cell identifier and a cell frequency point.

Take a search strategy for learning a 5G network system as an example.

Among the 5G network systems, a 5G network system including non-independent Networking (NSA) and a 5G network system including independent networking (Stand Alone, SA) are included.

In the 5G network system of NSA, when a terminal device uses a 5G cellular network, the terminal device establishes a dual connection channel with a 4G cell and a 5G cell of NSA, and a control plane of the 5G cell is anchored in the 4G cell and uses a 4G core network.

In the 5G network system of the SA, when the terminal device uses a 5G cellular network, the terminal device establishes a connection channel with a 5G cell of the SA.

In addition, the terminal device supporting the 5G network system of NSA does not perform measurement of the 5G cell in an idle (idle) state.

1.1, learning a search strategy of the terminal equipment of the 5G network system supporting NSA in an idle state.

Since the terminal device supporting the NSA in the 5G network system does not measure the 5G cell in an idle state, the search policy of the terminal device supporting the NSA in the 5G network system in the idle state may include the target network identifier record and the cell information of the target cell, where the target cell is the 4G cell supporting the NSA.

When the terminal equipment is in an idle state, monitoring a system message sent by a base station of a cellular network cell which is currently connected with the terminal equipment. The system message may include more than one of cell identifier of the measurement cell, measurement frequency, measurement starting condition, measurement result reporting trigger condition, measurement time period, and other information.

If the cellular network cell to which the terminal device is currently connected does not support the 5G network standard of the NSA, the terminal device may search for a 4G cell supporting the NSA according to the system message.

As shown in fig. 4, when learning a search policy of a terminal device supporting a 5G network scheme of NSA in an idle state, the terminal device may obtain information on whether each policy cell supports the 5G network scheme of NSA and a historical network measurement result of each policy cell.

For a policy cell that does not support NSA, the terminal device may obtain whether a 4G cell that supports NSA exists in the historical network measurement results of the policy cell.

If the 4G cell supporting the NSA exists in the historical network measurement result of the policy cell and the network state of the 4G cell supporting the NSA meets the preset threshold condition, the terminal device may determine the 4G cell supporting the NSA as a target cell, record the content of the target network identifier as a first identifier, record the target network identifier and the cell information of the target cell in a search policy, and associate the search policy with the cell information of the policy cell.

If the 4G cell supporting NSA does not exist in the historical network measurement results of the strategy cell, or the network state of the 4G cell supporting NSA does not meet the preset threshold value condition, the terminal device does not record the search strategy, or the terminal device records the content of the target network identifier as a second identifier, then records the target network identifier in the search strategy, and associates the search strategy with the cell information of the strategy cell.

The following description will be made of the content shown in 1.1 with reference to a specific application scenario.

The application scene one:

as shown in fig. 5, the terminal device 504 of the 5G network system supporting NSA is once connected to the 4G cell 501, the 4G cell 502, and the 4G cell 503 in the target area, and therefore, the terminal device 504 determines the 4G cell 501, the 4G cell 502, and the 4G cell 503 as the policy cell.

The terminal device 504 acquires information whether the 4G cell 501, the 4G cell 502, and the 4G cell 503 support the 5G network system of NSA, and determines that the 4G cell 501 and the 4G cell 503 do not support the 5G network system of NSA and the 4G cell 502 supports the 5G network system of NSA according to the information.

In the historical network measurement results of both the 4G cell 501 and the 4G cell 503, the 4G cell 502 may be searched, and the network status of the 4G cell 502 meets the preset threshold condition.

Therefore, the terminal device 504 may determine the 4G cell 502 as a target cell, record the content of the target network identifier as a first identifier, record the target network identifier and the cell information of the 4G cell 502 in the search policy, establish and store an association relationship between the search policy and the cell identifier of the 4G cell 501 and the cell identifier of the 4G cell 503.

It should be noted that the manner of acquiring the information whether the 4G cell supports the 5G network system of the NSA may be set according to an actual situation. For example, in some embodiments, the terminal device may determine, in the cell information of the 4G cell, whether the 4G cell supports the 5G network standard of NSA; in other embodiments, the terminal device may collect display information of a 5G icon in a human-computer interaction interface from an Application Processor (AP), and determine a 4G cell that can display the 5G icon as a 4G cell of a 5G network system that supports NSA; in other embodiments, the terminal device may configure the network measurement configuration information configured with the 5G cell, and determine the 4G cell that the 5G cell may be measured by the terminal device as the 4G cell supporting the 5G network standard of the NSA.

1.2, learning a search strategy of the terminal equipment of the 5G network system supporting NSA in a connection state.

As shown in fig. 6, it is assumed that a modulation network selection unit, a network selection policy unit, and an environment sensing unit are provided in the terminal device.

Wherein, the modulation network selection unit can search and record historical information. The history information may include one or more of location information of the terminal device history, network measurement configuration information, network measurement results, cell information of a 4G cell (i.e., a policy cell) that has been connected, whether the 4G cell supports NSA, a connection status, a 5G mode, and the like.

When the terminal device learns the search strategy, the modulation network selection unit can transmit the history information to the environment sensing unit.

The environment sensing unit identifies the environment according to the historical information, identifies a fixed place (namely a target area) or a fixed route (namely a target path), and transmits the historical information corresponding to the target area or the target path to the network selection strategy unit.

And after reading the history information, the network selection strategy unit learns the network searching strategy according to the strategy cell corresponding to the target area or the target path.

When the policy cell is a cellular network cell of the target area, the search policy may include a target network type identifier, cell information of the 5G cell, and cell information of the preferred cell.

And the terminal equipment acquires the cell information of each policy cell and the historical network measurement result of each policy cell.

If no 5G cell is searched in the historical network measurement results of each policy cell, or the network state of the searched 5G cell does not meet the preset threshold condition, the terminal device may record the target network type identifier as the second identifier, record the target network type identifier in the search policy, and establish and store an association relationship between the search policy and the cell information of each policy cell in the fixed area.

If the 5G cell with the network state meeting the preset threshold value condition exists in the historical network measurement result of each policy cell, the terminal equipment can record the target network system identifier as a first identifier, acquire the cell information of the 5G cell, determine the 4G cell supporting the 5G cell as the preferred cell, record the target network system identifier, the cell information of the 5G cell and the cell information of the preferred cell in a search policy, and establish the association relationship between the search policy and the cell information of each policy cell in the fixed area.

When the policy cell is the cellular network cell of the target path, the search policy may include a target network type identifier, cell information of the 5G cell, cell information of the preferred cell, and start-stop information.

The start-stop information represents the effective range of the search strategy, and the specific content of the start-stop information can be set according to the actual situation. For example, when the start-stop information is a preset time length, it indicates that the search policy is only effective within the preset time length; when the start-stop information is a preset area, the search strategy is only effective in the preset area; when the start-stop information is the cell information of the policy cell, it indicates that the search policy is only valid for the currently connected policy cell, and when the terminal device switches to the next cellular network cell, the search policy is invalid.

As shown in fig. 7, the terminal device obtains cell information of each policy cell and a historical network measurement result of each policy cell.

If the 5G cell is not searched in the historical network measurement result of the policy cell, or the network state of the searched 5G cell does not satisfy the preset threshold condition, the terminal device may record the target network system identifier as the second identifier, record the target network system identifier and the start-stop information in the search policy, and establish an association relationship between the search policy and the cell information of the policy cell.

If the historical network measurement result of the policy cell includes a 5G cell whose network state meets the preset threshold condition, the terminal device may record the target network format identifier as the first identifier, acquire cell information of the 5G cell, determine a 4G cell supporting the 5G cell as the preferred cell, record the target network format identifier, the cell information of the 5G cell, the cell information of the preferred cell, and start/stop information in a search policy, and establish an association relationship between the search policy and the cell information of the policy cell.

And traversing the historical network measurement result of each strategy cell by the terminal equipment to obtain the search strategy corresponding to each strategy cell.

1.3, learning a search strategy of the terminal equipment of the 5G network system supporting the SA.

As shown in fig. 8, it is assumed that a modulation network selection unit, a network selection policy unit, and an environment sensing unit are provided in the terminal device.

Wherein, the modulation network selection unit can search and record historical information. The history information may include one or more of location information of a history of the terminal device, cell information of a 4G cell once connected, a connection state, a 5G mode, network measurement configuration information, a network measurement result, and the like.

And after reading the historical information, the network selection strategy unit learns the network searching strategy according to the strategy cell corresponding to the target area or the target path.

Under the 5G network standard of the SA, the search policy of the terminal device may include a target network standard identifier and cell information of the 5G cell.

As shown in fig. 9, when learning the search policy, the network selection policy unit may acquire cell information of a next hop cell of the policy cell. The next-hop cell is a cellular network cell connected after the next cell switching operation after the terminal device is connected to the policy cell in the history record.

If the next hop cell of the policy cell is the 5G cell, the network selection policy unit may record the target network system identifier as the first identifier, acquire cell information of the 5G cell, record the target network system identifier and the cell information of the 5G cell in the search policy, and establish and store an association relationship between the search policy and the cell information of the policy cell.

If the next hop cell of the policy cell is not the 5G cell, the network selection policy unit may obtain historical network measurement configuration information of the measurement 5G neighbor cell of the policy cell;

if the policy cell has no historical network measurement configuration information, the terminal device may record the target network system identifier as the second identifier, record the target network system identifier in the search policy, and establish and store an association relationship between the search policy and the cell information of the policy cell.

If the policy cell has the historical network measurement configuration information, the network selection policy unit may obtain the historical network measurement result of the policy cell.

If the 5G cell is not searched in the historical network measurement result of the policy cell, or the network state of the searched 5G cell does not satisfy the condition of the preset threshold value, the network selection policy unit may record the target network type identifier as the second identifier, record the target network type identifier in the search policy, and establish and store the association relationship between the search policy and the cell information of the policy cell.

If the 5G cell whose network state satisfies the preset threshold condition exists in the historical network measurement result of the policy cell, the network selection policy unit may record the target network system identifier as the first identifier, acquire cell information of the 5G cell, record the target network system identifier and the cell information of the 5G cell in the search policy, establish an association relationship between the search policy and the cell information of the policy cell, and store the association relationship.

In addition, since the user is usually in a moving state on the target path and does not stay in a certain area, the terminal device should change the search strategy in time according to the actual situation. Therefore, when the policy cell is a cellular network cell of a fixed path, start-stop information may be set in the search policy, the effective range of the search policy may be limited by the start-stop information, and when the effective range is not satisfied, the search policy may be invalidated and the terminal device may reselect the search policy.

It can be understood that, in the above-described learning process of the search strategy, the strategy cell and the search strategy corresponding to the strategy cell need to be determined according to the history information of the terminal device. However, the above description should not be construed as limiting the learning process of the search policy, and in other embodiments, the terminal device may not determine the policy cell and the search policy corresponding to the policy cell according to the history information of the terminal device.

For example, in some embodiments, the search policy cell and the search policy corresponding to the policy cell may be preset by a developer. In other embodiments, the terminal device may obtain coverage area information of each cellular network cell from an operator of the cellular network, and further determine the policy cell and the search policy corresponding to the policy cell according to the coverage area information of each cellular network cell.

The embodiment of the application does not limit the process of learning the search strategy by the terminal equipment.

2. And searching the network according to the search strategy.

Referring to fig. 10, fig. 10 shows another network measurement method provided in this embodiment, including:

s1001, when the first position information of the terminal equipment meets a preset trigger condition, acquiring cell information of a cellular network cell connected with the terminal equipment.

When the terminal device is in a cellular network cell of a non-target network system and the first location information of the terminal device meets a preset trigger condition, the terminal device may enter a low-power-consumption network searching mode to acquire cell information of the cellular network cell connected with the terminal device.

The manner of acquiring the first position information may be set according to actual conditions. In some embodiments, the first location information may be obtained by a Global Positioning System (GPS); in other embodiments, the first location information may be obtained by a beidou positioning system; in other embodiments, the first location information may be obtained by wifi positioning technology; alternatively, in another embodiment, the first location information may be one or more of information such as a set of cells (e.g., a combination of a serving cell and a neighboring cell), a WiFi network identifier, a Media Access Control Address (MAC) identifier, and the like, and the terminal device may obtain corresponding information from an internal module of the base station or the terminal device.

In some possible implementation manners, the preset trigger condition is that the terminal device is in the target area.

At this time, the terminal device may monitor the first location information, where the first location information is location information of a location where the terminal device is currently located.

When the terminal device detects that the first position information is in the target area, the preset trigger condition is met, the terminal device enters a low-power-consumption network searching mode, and cell information of a cellular network cell connected with the terminal device is obtained.

In other possible implementation manners, the preset trigger condition is that the terminal device is on the target path.

At this time, the terminal device may monitor the first location information. And when the terminal equipment detects that the first position information is on the target path, the preset trigger condition is met, the low-power-consumption network searching mode is entered, and the cell information of the cellular network cell connected with the terminal equipment is acquired.

S1002, inquiring a search strategy corresponding to the cell information, and executing corresponding network measurement operation according to the search strategy.

In the low-power network searching mode, the terminal device may query a search strategy corresponding to the cell information.

If the search strategy associated with the cell information exists, the terminal device may acquire the target network type identifier in the search strategy.

And if the target network system identifier is the first identifier, the terminal equipment executes corresponding network measurement operation according to the cell information of the target cell in the search strategy. In some possible implementations, the target cell may be a cellular network cell of the target network type. In other possible implementations, the target cell may not be a cellular network cell of the target network type.

For example, assuming that the target network standard is a 5G network standard supporting NSA, in this case, the target cell may be a 5G cell of the 5G network standard supporting NSA, or the target cell may also be a 4G cell of the 5G network standard supporting NSA.

The cell information of the target cell may include a target cell identifier and a target cell frequency point, or only include one of the cell identifier and the cell frequency point. The terminal equipment can switch the communication frequency to the frequency point of the target cell to carry out network measurement operation, then determines the target cell from the searched cellular network cells according to the target cell identification, and establishes connection with the target cell.

If the target network type identifier is the second identifier, the terminal device may stop searching for the cellular network cell of the target network type, or the terminal device may change a search interval for searching for the cellular network cell of the target network type from a first preset time to a second preset time, where the first preset time is shorter than the second preset time, so as to reduce measurement power consumption consumed by searching for the cellular network of the target network type.

And if the search strategy associated with the cell information does not exist, the terminal equipment executes corresponding network measurement operation according to the network measurement configuration information or the system message sent by the base station of the cellular network cell.

And, when the start-stop information is included in the search policy, the terminal device should enable or replace the search policy according to the start-stop information in the search policy. For example, if a certain search policy includes start-stop information, and the content of the start-stop information is 2 seconds, it indicates that the effective time of the search policy is 2 seconds. At this time, the terminal device should deactivate the search strategy 2 seconds after using the search strategy, and determine the search strategy that needs to be used currently again according to the cell information of the cellular network cell to which the terminal device is currently connected.

Take the example that the terminal device searches for the 5G cell.

2.1, when the terminal equipment of the 5G network system supporting NSA is in an idle state, the terminal equipment does not search the 5G cell. At this time, the terminal device may detect whether the currently connected cellular network cell supports the 5G network standard of NSA. If not, acquiring the cell information (such as cell identification) of the cell of the cellular network, and inquiring the idle-state search strategy associated with the cell information.

And if the idle-state search strategy associated with the cell information exists, the terminal equipment acquires a target network identifier in the search strategy.

And if the target network identifier is the first identifier, the terminal equipment acquires the cell information of the target cell in the search strategy, searches the target cell according to the cell information of the target cell and switches to the target cell.

If the target network identifier is the second identifier, the terminal device stops executing the network measurement operation, or the terminal device may change the search interval for executing the network measurement operation from the first preset duration to the second preset duration.

And if the idle-state search strategy associated with the cell information does not exist, the terminal equipment executes network measurement operation according to the system message broadcasted by the base station of the currently connected cellular network cell.

When the terminal device is in a connected state and meets a preset trigger condition, the terminal device may obtain cell information (e.g., a cell identifier) of a cellular network cell to which the terminal device is currently connected, and query a search policy associated with the cell information.

For example: as shown in fig. 11, it is assumed that a modulation network selection unit, a network selection policy unit, and an environment sensing unit are provided in the terminal device.

And after learning the search strategy, the network selection strategy unit stores the search strategy.

In the operation process of the terminal device, the modulation network selection unit may transmit cell information, a connection state, a 5G mode, and other information of a currently connected 4G cell to the environment sensing unit.

And the environment sensing unit identifies the environment according to the information transmitted by the modulation network selection module and identifies whether the terminal equipment is in a fixed scene or a fixed route at present.

The context awareness unit may then pass the identification result (i.e. information of the fixed location or fixed route where the terminal device is located) to the network selection policy unit.

And the network selection strategy unit performs matching according to the identification result, determines a search strategy matched with the 4G cell currently connected with the terminal equipment, and transmits the matched search strategy to the modulation network selection module.

And the modulation network selection unit executes corresponding network measurement operation according to the search strategy.

After the terminal device queries the search policy, if there is a search policy associated with the cell information, the terminal device may obtain a target network type identifier in the search policy.

And if the target network type identifier is the first identifier, judging whether the cellular network cell currently connected with the terminal equipment supports the 5G network type of NSA.

If the cellular network cell to which the terminal equipment is currently connected supports the 5G network system of NSA, acquiring cell information of the 5G cell in a search strategy, searching the 5G cell according to the cell information of the 5G cell and establishing connection with the 5G cell.

If the cellular network cell to which the terminal device is currently connected does not support the 5G network mode of NSA, the terminal device may acquire cell information of a preferred cell in a search strategy, search the preferred cell according to the cell information of the preferred cell, reselect or switch to the preferred cell, then search the 5G cell according to the cell information of the 5G cell and establish connection with the 5G cell, thereby avoiding that the terminal device cannot enter a 5G mode because the terminal device resides in a 4G cell that does not support NSA.

If the target network system identifier is the second identifier, the terminal device does not search the 5G cell, or the terminal device may change the search interval for searching the 5G cell from a first preset time to a second preset time, where the first preset time is shorter than the second preset time, so as to enlarge the search interval for searching the 5G cell.

And after the terminal equipment performs the network measurement operation of the 5G cell, the network measurement result is obtained. If the network measurement result is that no 5G cell exists or the signal intensity of the 5G cell is lower than the preset intensity threshold, the terminal device may stop searching for the 5G cell, or further increase the search interval for searching for the 5G cell, and change the search interval from the second preset duration to a third preset duration, where the third preset duration is greater than the second preset duration.

The first preset time, the second preset time and the third preset time may be set according to actual conditions, for example, in some embodiments, the first preset time may be set to 100 milliseconds, the second preset time may be set to 1 second, and the third preset time may be set to 2 seconds.

Furthermore, if there is no search policy associated with the cell information, the terminal device may perform a corresponding network measurement operation according to network measurement configuration information transmitted by the base station of the currently connected cellular network cell.

2.2, when the terminal device of the 5G network system supporting the SA meets the preset trigger condition, the terminal device can acquire the cell information of the currently connected cellular network cell and inquire the search strategy associated with the cell information.

And if the search strategy associated with the cell information exists, acquiring a target network type identifier in the search strategy.

And if the target network system identifier is the first identifier, the terminal equipment acquires the cell information of the 5G cell in the search strategy, searches the 5G cell according to the cell information of the 5G cell and establishes connection with the 5G cell.

If the target network type identifier is the second identifier, the terminal device does not search the 5G cell, or the terminal device may change the search interval for searching the 5G cell from a first preset time length to a second preset time length, where the first preset time length is smaller than the second preset time length, so as to enlarge the search interval for searching the 5G cell.

And after the terminal equipment performs the network measurement operation of the 5G cell, the network measurement result can be obtained. If the network measurement result is that no 5G cell exists or the signal intensity of the 5G cell is lower than the preset intensity threshold, the terminal device may stop searching for the 5G cell, or further increase the search interval for searching for the 5G cell, and change the search interval from the second preset duration to a third preset duration, where the third preset duration is greater than the second preset duration.

If there is no search strategy associated with the cell information, the terminal device may perform a corresponding network measurement operation according to the network measurement configuration information sent by the base station of the currently connected cellular network cell.

Furthermore, when start-stop information is included in the search policy, the terminal device should enable or replace the search policy according to the start-stop information in the search policy. For example, if a certain search policy includes start-stop information, and the content of the start-stop information is 2 seconds, it indicates that the effective time of the search policy is 2 seconds. At this time, the terminal device should deactivate the search strategy 2 seconds after using the search strategy, and determine the search strategy that needs to be used currently again according to the cell information of the cellular network cell to which the terminal device is currently connected.

The network measurement method provided in this embodiment is described below with reference to a specific application scenario.

Application scenario two:

As shown in fig. 12, the terminal device 1204 has once connected to the 4G cell 1201, the 4G cell 1202, and the 4G cell 1203 within the target area, and therefore the terminal device 1204 takes the 4G cell 1201, the 4G cell 1202, and the 4G cell 1203 as the policy cell.

Terminal device 1204 obtains historical network measurement results associated with 4G cell 1201, 4G cell 1202, and 4G cell 1203.

In the historical network measurement result, if a 5G cell is not searched, the terminal device 1204 sets the value of the target network system identifier to 0,0 indicates that no 5G cell exists, and then the terminal device 1204 records the target network system identifier in the search policy a, and establishes and stores the association relationship between the search policy a and the cell identifier of the 4G cell 1201, the cell identifier of the 4G cell 1202, and the cell identifier of the 4G cell 1203.

Subsequently, when the user comes to the target area again, the terminal device 1204 detects that the first location information is in the target area, and then acquires the cell identifier of the currently connected 4G cell 1202.

The terminal device 1204 obtains the target network system identifier of the search policy a, and when detecting that the value of the target network system identifier is 0, the terminal device 1204 stops searching for the 5G cell, thereby reducing the measurement power consumption for searching for the 5G cell.

Application scenario three:

in the scenario shown in fig. 13, the dashed circle represents the target area and the solid circle represents the coverage area of a cellular network cell. The terminal device 1305 supports the 5G network system of NSA.

As shown in fig. 13, terminal device 1305 has been connected to 4G cell 1301, 4G cell 1302, and 4G cell 1303 in the target area, and therefore terminal device 1305 uses 4G cell 1301, 4G cell 1302, and 4G cell 1303 as the policy cell.

Terminal device 1305 obtains historical network measurements associated with 4G cell 1301, 4G cell 1302, and 4G cell 1303.

In the historical network measurement results associated with the 4G cell 1302, the 5G cell 1304 is searched, and the signal intensity of the 5G cell 1304 is greater than the preset intensity threshold, the terminal device 1305 acquires the cell identifier and the cell frequency point of the 5G cell 1304, and sets the value of the target network standard identifier to 1,1 to indicate that the 5G cell exists. In addition, the terminal device 1305 queries that the 4G cell 1301 and the 4G cell 1302 do not support the 5G network standard of NSA, and the 4G cell 1303 supports the 5G network standard of NSA, so that the terminal device 1305 takes the 4G cell 1303 as a preferred cell to obtain the cell identifier and the cell frequency point of the 4G cell 1303.

And then recording the target network standard identifier, the cell identifier of the 5G cell 1304, the cell frequency point of the 5G cell 1304, the cell identifier of the 4G cell 1303 and the cell frequency point of the 4G cell 1303 in a search strategy B, and establishing and storing an association relation between the search strategy B and the cell identifiers of the 4G cell 1301, the 4G cell 1302 and the 4G cell 1303.

Subsequently, when the user comes to the target area again, the terminal device 1305 detects that the first location information is within the target area, and then acquires the cell identifier of the currently connected 4G cell 1302.

The terminal device 1305 queries the search policy corresponding to the cell identifier of the 4G cell 1302 to obtain a search policy B.

The terminal device 1305 obtains the target network system identifier of the search policy B, and detects that the value of the target network system identifier is 1, the terminal device 1305 obtains the cell identifier of the 4G cell 1303 and the cell frequency point of the 4G cell 1303 in the search policy B, searches the 4G cell 1303 according to the cell identifier of the 4G cell 1303 and the cell frequency point of the 4G cell 1303, and establishes connection with the 4G cell 1303.

Then, the terminal device 1305 acquires the cell identifier of the 5G cell 1304 and the cell frequency point of the 5G cell 1304 in the search policy B, searches the 5G cell 1304 according to the cell identifier of the 5G cell 1304 and the cell frequency point of the 5G cell 1304, and establishes connection with the 5G cell 1304.

And an application scene four:

in the scenario shown in fig. 14, the dashed line represents the target path and the solid circle represents the coverage area of the cellular network cell.

As shown in fig. 14, the terminal device 1404 has once connected to the 4G cell 1401 and the 4G cell 1402 on the target path, and therefore the terminal device 1404 uses the 4G cell 1401 and the 4G cell 1402 as the policy cell.

The terminal device 1404 acquires historical network measurement results associated with the 4G cell 1401 and the 4G cell 1402.

Since the target path does not pass through the coverage of the 5G cell 1403, in the historical network measurement result of the 4G cell 1401, the 5G cell is not searched, the terminal device 1404 sets the value of the target network standard identifier to 0,0 indicates that the 5G cell does not exist, and records the cell identifier of the 4G cell 1401 as start-stop information. Then, the terminal device 1404 records the target network system identifier and the start-stop information in the search policy C, and establishes and stores an association relationship between the search policy C and the cell identifier of the 4G cell 1401.

And, in the historical network measurement result of the 4G cell 1402, the 5G cell is not searched, the terminal device 1404 sets the value of the target network standard identifier to 0, where 0 indicates that there is no 5G cell, and records the cell identifier of the 4G cell 1402 as the start-stop information. Then, the terminal device 1404 records the target network system identifier and the start-stop information in the search policy D, and establishes and stores an association relationship between the search policy D and the cell identifier of the 4G cell 1402.

When the user walks the target path again, the terminal device 1404 detects that the first location information is on the target path, and then obtains the cell identifier of the currently connected 4G cell 1401.

The terminal device 1404 queries the search strategy corresponding to the cell identifier of the 4G cell 1401 to obtain a search strategy C.

The terminal device 1404 obtains the target network format identifier of the search policy C, and when detecting that the value of the target network format identifier is 0, the terminal device 1404 stops searching for the 5G cell, thereby reducing the measurement power consumption for searching for the 5G cell.

After the terminal device 1404 switches from the 4G cell 1401 to the 4G cell 1402, the terminal device 1404 detects that the cell identifier of the 4G cell 1402 is not consistent with the start-stop information of the search policy C, and then stops using the search policy C.

At this time, the terminal device 1404 queries the search policy corresponding to the cell identifier of the 4G cell 1402, and obtains a search policy D.

The terminal device 1404 obtains the target network format identifier of the search policy D, and when detecting that the value of the target network format identifier is 0, the terminal device 1404 stops searching for the 5G cell, thereby reducing the measurement power consumption for searching for the 5G cell.

As shown in fig. 15, the terminal device 1504 has connected to the 4G cell 1501, the 4G cell 1502, and the 5G cell 1503 on the target path in the order of the 4G cell 1501, the 4G cell 1502, and the 5G cell 1502.

When learning the search strategy of the 4G cell 1501, the terminal device 1504 detects that the 4G cell 1501 next hop cell is the 4G cell 1502, and in the historical network measurement results of the 4G cell 1501, no 5G cell is searched, the terminal device 1504 sets the value of the target network format identifier to 0,0 indicates that no 5G cell exists, and records the cell identifier of the 4G cell 1501 as start-stop information. Then, the terminal device 1504 records the target network type identifier and the start-stop information in the search policy E, and establishes and stores an association relationship between the search policy E and the cell identifier of the 4G cell 1501.

When learning the search strategy of the 4G cell 1502, the terminal device 1504 detects that the next-hop cell of the 4G cell 1502 is the 5G cell 1503, and then the terminal device 1504 sets the value of the target network format identifier to 1, which indicates that the 5G cell exists, and records the cell identifier of the 4G cell 1502 as start-stop information. Then, the terminal device 1504 records the target network standard identifier, the cell identifier of the 5G cell 1503, the cell frequency point of the 5G cell 1503, and the start-stop information in the search policy F, and establishes and stores the association relationship between the search policy F and the cell identifier of the 4G cell 1501.

When the user walks the target path again, the terminal device 1504 detects that the first location information is on the target path, and then acquires the cell identifier of the currently connected 4G cell 1501.

The terminal device 1504 queries the search policy corresponding to the cell identifier of the 4G cell 1501, and obtains the search policy E.

The terminal device 1504 acquires the target network type identifier of the search policy E, and when detecting that the value of the target network type identifier is 0, the terminal device 1504 stops searching for the 5G cell, thereby reducing the measurement power consumption for searching for the 5G cell.

After the terminal device 1504 switches from the 4G cell 1501 to the 4G cell 1502, the terminal device 1504 detects that the cell id of the 4G cell 1502 does not coincide with the start-stop information of the search strategy E, and stops using the search strategy E.

At this time, the terminal device 1504 queries the search policy F corresponding to the cell id of the 4G cell 1502 to obtain the search policy F.

The terminal device 1504 acquires a target network format identifier of the search policy F, and when detecting that the value of the target network format identifier is 1, acquires a cell identifier of a 5G cell 1503 and a cell frequency point of the 5G cell 1503 in the search policy F.

Then, the terminal device 1504 searches the 5G cell 1503 according to the cell identifier of the 5G cell 1503 and the cell frequency point of the 5G cell 1503, and establishes connection with the 5G cell 1503.

After the terminal device 1504 switches from the 4G cell 1502 to the 5G cell 1503, the terminal device 1504 stops using the search strategy F when detecting that the cell identifier of the 5G cell 1503 does not coincide with the start-stop information of the search strategy F.

In summary, in the network measurement method provided in the embodiment of the present application, the terminal device may learn the search policy from the history information by using the history information as the prior information. When the terminal device is connected to the cellular network cell, the terminal device may determine a corresponding search policy according to cell information of the currently connected cellular network cell, and perform a corresponding network measurement operation according to the search policy.

When the target network type identifier of the search strategy is the first identifier, the terminal device can search the cellular network cell of the target network type in a targeted manner according to the cell information of the cellular network cell, so that the search efficiency is improved, the terminal device can be connected with the cellular network cell of the target network type more quickly, the measurement power consumption is saved, and the endurance time of the terminal device is prolonged.

When the target network type identifier of the search strategy is the second identifier, the terminal device may stop searching the cellular network cell of the target network type, or may extend the search interval for searching the cellular network cell of the target network type, and reduce the search frequency, thereby reducing useless network measurement operations and saving measurement power consumption.

When the search strategy is learned, the terminal equipment can perform behavior recognition on the historical position information, determine a target area where the user often resides and/or a target path where the user walks, and learn the search strategy of each strategy cell in the target area and/or the target path, so that when the user is located in the target area and/or the target path, the terminal equipment can be quickly connected with the cellular network cell of the target network system, the measurement power consumption is reduced, and the use experience of the user is improved.
