The collected data comprises the signal quality of each operator network in each area and the network quality of the cloud site in each area. The operator networks include respective operator networks to which all terminal devices connected to the cloud site have access.

And the distribution server is used for forwarding data between the terminal equipment and the data center server.

And the data center server is used for determining the operator network and the cloud site meeting the specified conditions based on the data collected by the cloud site.

And the RSP is used for storing SIM card data of each operator network.

The terminal equipment is a terminal requesting access and is used for requesting access to an operator network and connecting a cloud site.

Under the network architecture, the terminal device is connected to the distribution server, and sends a connection request to the distribution server. And the distribution server forwards the connection request to the data center server. And the data center server determines a target operator network meeting a first specified condition and a target cloud station meeting a second specified condition according to the connection request and the data acquired by the cloud station, writes SIM card data belonging to the target operator network into the terminal equipment, and sends a station identifier of the target cloud station. And the distribution server forwards the site identification to the terminal equipment. Therefore, the terminal equipment is accessed to the target operator network according to the SIM card data, and is connected to the target cloud site in the target operator network according to the site identification.

The SIM card data belonging to the target operator network may be written to the terminal device in several ways, which are:

And secondly, the data center server sends the network identifier of the target operator network to the distribution server, so that the distribution server triggers RSP to write the SIM card data belonging to the target operator network into the terminal equipment.

And thirdly, the data center server acquires the SIM card data belonging to the target operator network from the RSP, sends the SIM card data to the distribution server, and forwards the SIM card data to the terminal equipment by the distribution server.

And the distribution server forwards the connection request sent by the terminal equipment to the data center server. And the data center server determines a target operator network meeting a first specified condition and a target cloud site meeting a second specified condition according to the acquired data and the connection request, so that the target operator network and the target cloud site with better quality and lower cost can be determined. And then the data center server writes the SIM card data belonging to the target operator network into the terminal equipment and informs the terminal equipment of the target cloud site. The terminal equipment is accessed to a target operator network according to the SIM card data and is connected to the target cloud site, so that higher communication quality between the terminal equipment and the target cloud site can be ensured, and the communication cost is reduced.

Referring to fig. 3, an embodiment of the present application provides a method for connecting a cloud site, where the method may be applied to the network architecture shown in fig. 1, and includes:

step 301: and the data center server acquires the data acquired by each cloud station.

Each cloud site is a cloud site that the data center server can manage. The device identification of the data center server can be stored in each cloud site, so that each cloud site sends data to the data center server based on the device identification, and the data center server manages each cloud site.

The acquired data comprises first signal quality of each operator network in each area and network quality of each cloud site in each area.

The acquired data includes first acquired data and second acquired data. The first collected data is used for describing first signal quality of each operator network in each area, and the second collected data is used for describing network quality of each cloud site in each area.

The first acquisition data comprises at least one piece of first data, which for each piece of first data comprises a network identification of the operator network, an area identification of the area and a first signal quality. The first data is used to describe a first signal quality of the operator network within the area.

The first data may comprise only a network identification of the operator network, an area identification of the area and the first signal quality. Alternatively, the first data may also comprise other information, for example, the first data can also comprise the network type of the operator network.

The network type of the operator network includes one or more of a 3G network type, a 4G network type, a 5G network type, and the like.

The second collected data includes at least one piece of second data, and for each piece of second data, the second data includes a site identifier of the cloud site, an area identifier of the area, and a network quality. The second data is used to describe the network quality of the cloud site within the area.

The second data may include only a site identification of the cloud site, an area identification of the area, and a network quality. Alternatively, the second data may also include other information, for example, the second data may also include a network identification of the operator network, such that the second data is used to describe the network quality of the cloud site within the region and under the operator network.

The detailed process of the data center server acquiring the acquired data will be described in detail in the following, and will not be described first.

For a new terminal device that needs to access a cloud site, the new terminal device needs to connect to the cloud site through an operator network, and for convenience of description, the new terminal device is referred to as a first terminal device. Or, for a terminal device connected to a cloud site, the terminal device has already accessed to an operator network, and the terminal device may need to switch to an operator network with higher signal quality or a cloud site with higher network quality in an area where the terminal device is located. The first terminal device is realized by the operations as steps 302 to 309.

Step 302: the first terminal device sends a connection request to the distribution server, the connection request including a device identification and location information of the first terminal device.

In this step, the first terminal device establishes a network connection with the distribution server, acquires its own location information, and sends a connection request to the distribution server through the network connection.

The position information of the first terminal device is an area identifier of a first area where the first terminal device is located or a coordinate of the first terminal device. The area identifier of the first area includes one or more of a cell identifier of a cell in which the first terminal device is located, an area code of a location area in which the first terminal device is located, and the like.

The cell in which the first terminal device is located and the location area in which the first terminal device is located may be the same or different. Under the condition that the two are different, the cell where the first terminal device is located may include a location area where the first terminal device is located, that is, the location area where the first terminal device is located is a part of the cell where the first terminal device is located. Alternatively, the location area where the first terminal device is located may include a cell where the first terminal device is located, that is, the cell where the first terminal device is located is a part of the location area where the first terminal device is located.

For the network connection, the process of the first terminal device establishing the network connection is as follows:

when the first terminal device is a new terminal device which needs to be accessed to the cloud site, one SIM card data belonging to a certain operator network is stored in the first terminal device when the first terminal device leaves a factory. The first terminal equipment accesses the operator network through the SIM card data, and establishes network connection with the distribution server in the operator network. Or, the first terminal device is connected to an access point, and establishes a network connection with the distribution server through the access point, where the access point may be an access point of a wifi network or a bluetooth access point.

When the first terminal device is a terminal device which has accessed to an operator network, the first terminal device directly establishes a network connection with the distribution server in the operator network.

For the location information, the process of the first terminal device obtaining the location information may be:

under the condition that the first terminal device is accessed to the operator network, because the operator network is a network to which mobile communication is accessed, and the first terminal device is located in a cell and a location area in the operator network, the first terminal device obtains an area identifier of a first area where the first terminal device is located from the operator network, or the first terminal device uses an access network element in the operator network to locate the first terminal device to obtain coordinates of the first terminal device, and the access network element can be a base station or the like. In the case where the first terminal device is connected to the access point, the first terminal device acquires its own position information by using the access point.

In case the first terminal device accesses the operator network, the access request may further comprise a network identification of the operator network. And/or, when the first terminal device is connected to the cloud site, the access request may further include a site identification of the cloud site.

Step 303: and the distribution server receives the connection request and sends the connection request to the data center server.

And under the condition that the position information included in the connection request is the coordinate, the distribution server acquires the area identifier of the first area where the first terminal equipment is located according to the coordinate, replaces the coordinate included in the connection request with the area identifier, and then sends the connection request to the data center server. Or the distribution server does not process the coordinates and sends the connection request to the data center server, wherein the connection request comprises the position information and is still the coordinates.

Step 304: and the data center server receives the connection request, and determines a target operator network meeting a first specified condition according to the position information included in the connection request and the acquired data.

Wherein the first specified condition comprises at least one of an operator network whose signal quality exceeds a first quality threshold, an operator network capable of providing the first terminal device subscription package, and an operator network with the lowest cost.

In this step, the data center server may determine the target operator network through the following operations 3041 to 3043. The operations 3041 through 3043 are, respectively:

3041: and the data center server determines the area identifier of the first area where the first terminal equipment is located according to the position information of the first terminal equipment.

And under the condition that the position information included in the connection request is the area identifier, taking the position information included in the connection request as the area identifier of the first area where the first terminal equipment is located. And under the condition that the position information included in the connection request is the coordinate, determining a first area where the first terminal device is located according to the coordinate, and acquiring an area identifier of the first area.

3042: and the data center server acquires the first signal quality of each operator network in the first area according to the area identification of the first area.

At 3042, according to the area identifier of the first area, network identifiers of corresponding operator networks and first signal qualities of the operator networks in the first area are obtained from the first collected data.

And under the condition that each piece of first data in the first collected data further comprises the network type of the operator network, according to the area identifier of the first area, the network type of each operator network can be further acquired from the first collected data.

3043: the data center server determines one operator network meeting a first specified condition as a target operator network according to the first signal quality of each operator network in the first area.

At 3043, the data center server determines, according to the first signal quality of each operator network in the first area, a network identifier of one operator network whose first signal quality exceeds a first quality threshold from the obtained network identifiers of each operator network, where the operator network corresponding to the determined network identifier is the target operator network.

Since the first signal quality of the target operator network exceeds the first quality threshold, the service transmission efficiency is improved when the first terminal device transmits the service using the target operator network after accessing the target operator network.

The conditions under which the data center server determines the target operator network may include only the first signal quality of the operator network, or may include other conditions. For example, in one possible implementation, the other condition includes a package to which the first terminal device subscribes, that is, the condition under which the data center server determines that the target operator network depends includes the first signal quality of the operator network and the package to which the first terminal device subscribes. In this example, the process of determining the target operator network may be:

the data center server determines a package subscribed by the first terminal device according to the device identifier of the first terminal device, determines the network identifiers of the operator networks capable of providing the package from the obtained network identifiers of the operator networks, determines the network identifier of one operator network with the first signal quality exceeding a first quality threshold from the network identifiers of the operator networks capable of providing the package, and determines the operator network corresponding to the determined network identifier as a target operator network.

The determined target operator network can provide the package subscribed by the first terminal device, so that the first terminal device can transmit services by using the operator network after accessing the target operator network.

The process of determining the package subscribed by the first terminal device may include: the data center server obtains package identifiers subscribed by the first terminal device from package subscription data according to the device identifiers of the first terminal device, the package subscription data comprises at least one piece of subscription data, for each piece of subscription data, the subscription data comprises the device identifiers of the terminal device and the package identifiers of packages, and the subscription data is used for describing that the terminal device subscribes to the packages. And the data center server determines the package subscribed by the first terminal device according to the package identifier. Wherein, the package subscription data can be stored in the data center server. The user may subscribe the package for the first terminal device in advance, and a piece of subscription data exists in the package subscription data, where the subscription data includes a device identifier of the first terminal device and a package identifier of the package subscribed for the first terminal device.

Wherein determining the network identification of the operator network capable of providing the package may comprise: the package subscribed by the first terminal device may define a network type of an operator network capable of providing the package, and the data center server further obtains the network type of each operator network in operation 3042. At 3043, a network identifier of the operator network that can provide the package is determined from the network identifiers of the operator networks according to the network type of the operator network defined by the package. Or,

and the data center server acquires the network identifiers of the operator networks capable of providing the package according to the package identifier of the package subscribed by the first terminal equipment, the network identifiers of the operator networks and the package attribution data. The package attribution data comprises at least one piece of attribution data, and for each piece of attribution data, the attribution data comprises a package identification of the package and a network identification of an operator network, and the attribution data is used for describing that the operator network provides the package. The package attribution data may be stored in a data center server.

In another possible implementation, the other condition further includes a price at which the respective operator network offers the package, that is, the condition on which the data center server determines that the target operator network is based includes the first signal quality of the operator network, the package to which the first terminal device subscribes, and the price at which the operator network offers the package. In this example, the process of determining the target operator network may be:

for the operator networks capable of providing the package, the data center server further obtains the price of the package provided by each operator network, determines the network identifier of the operator network with the first signal quality exceeding the first quality threshold and the lowest price of the package from the network identifiers of the operator networks capable of providing the package, and determines the operator network corresponding to the determined network identifier as the target operator network, so as to determine the network identifier of the operator network with the first signal quality exceeding the first quality threshold and the lowest cost.

The price of the package subscribed by the first terminal equipment provided by the target operator network is the lowest, so that the first terminal equipment transmits services by using the target operator network, and the use cost can be reduced.

Optionally, the data center server obtains, from package price data, a price of the package provided by each operator network according to the package identifier subscribed by the first terminal device and the network identifier of each operator network. The package price data comprises at least one piece of price data, for each piece of price data, the price data comprises package identification of the package, network identification of an operator network and price, and the price data is used for describing the price of the package provided by the operator network.

Step 305: and the data center server determines a target cloud site meeting a second specified condition according to the position information and the acquired data.

The second specified condition includes at least one of a cloud site and a lowest-cost cloud site, etc., for which the network quality exceeds a second quality threshold.

In this step, the data center server may determine the target cloud site through the following operations 3051 to 3052. The operations 3051-3052 are respectively as follows:

3051: and the data center server acquires the network quality of each cloud site in the first area according to the area identification of the first area.

Under the condition that each piece of second data in the second acquired data comprises the area identifier of the area, the site identifier of the cloud site and the network quality, the data center server acquires the corresponding site identifier of each cloud site and the network quality of each cloud site in the first area from the second acquired data according to the area identifier of the first area.

Under the condition that each piece of second data in the second acquired data further comprises a network identifier of an operator network, the data center server acquires corresponding site identifiers of cloud sites and network quality of the cloud sites in the first area and under the target operator network from the second acquired data according to the area identifier of the first area and the network identifier of the target operator network.

3052: and the data center server determines a target cloud station meeting a second specified condition according to the acquired network quality.

At 3052, the data center server determines, from the obtained site identifiers of the cloud sites, a site identifier of a cloud site of which the network quality exceeds a second quality threshold, where a cloud site corresponding to the determined site identifier is a target cloud site.

Because the network quality of the target cloud site exceeds the second quality threshold, the service transmission efficiency is improved when the first terminal device is connected to the target cloud site and transmits the service with the target cloud site.

The conditions under which the data center server determines the target cloud site may include only the network quality of the cloud site, or may include other conditions. For example, in one possible implementation manner, the other condition includes a service price provided by the cloud site, so that in 3052, the data center server obtains the service price provided by each cloud site according to the obtained site identifier of each cloud site; and the data center server determines the station identifier of the cloud station with the network quality exceeding a second quality threshold and the provided service price being the lowest from the acquired station identifiers of the cloud stations, wherein the cloud station corresponding to the determined station identifier is the target cloud station with the network quality exceeding the second quality threshold and the cost being the lowest.

Due to the fact that the price of the service provided by the target cloud site is the lowest, the use cost of the user can be reduced after the first terminal device is connected to the target cloud site.

The process of the data center server acquiring the service prices provided by the cloud sites may be as follows: the data center server obtains the service price provided by each cloud site from service price data according to the site identification of each cloud site, wherein the service price data comprises at least one piece of price data, the price data comprises the site identification of the cloud site and the service price, and the price data is used for describing the service price of the service provided by the site. Wherein the service price data can be stored in a data center server.

Wherein, the description is: step 304 may be performed first, and then step 305 may be performed; alternatively, step 305 and step 304 may be performed simultaneously; alternatively, step 305 may be performed first, followed by step 304.

However, when the station identifier of each cloud station is acquired at 3051, if the network identifier of the target operator network needs to be used as the acquisition condition, the step 304 needs to be executed first, and then the step 305 needs to be executed.

In the case of executing step 305, the data center server needs to determine the area identifier of the first area where the first terminal device is located according to the location information of the first terminal device, and then determine the target cloud site according to the area identifier and the acquired data.

Step 306: the data center server sends a first connection response to the distribution server, wherein the first connection response comprises the network identifier of the target operator network and the site identifier of the target cloud site.

In the case where the first terminal device has accessed the operator network, the data center server also determines whether the operator network to which the first terminal device has accessed and the target operator network are the same. And in the case that the connection response comprises the network identification of the target operator network, the data center server triggers the first terminal equipment to switch from the accessed operator network to the target operator network by using the connection response. In the case that the connection response does not include the network identifier of the target operator network, the first terminal device may not switch the operator network.

The determining, by the data center server, whether the operator network to which the first terminal device has access and the target operator network operate identically may be: and under the condition that the connection request comprises the network identifier of the operator network accessed by the first terminal equipment, the data center server compares the network identifier of the accessed operator network with the network identifier of the target operator, if the network identifier of the accessed operator network is the same as the network identifier of the target operator, the operator network accessed by the first terminal equipment is determined to be the same as the network identifier of the target operator, and if the network identifier of the accessed operator network is different from the network identifier of the target operator, the operator network accessed by the first terminal equipment is determined to be different from the network identifier of the target operator.

In the case that the first terminal device is connected to the cloud site, the data center server further determines whether the cloud site to which the first terminal device is connected and the target cloud site are the same. And under the condition that the connection response comprises the station identification of the target cloud station, the data center server triggers the first terminal device to switch from the connected cloud station to the target cloud station by using the connection response. In this case, the first terminal device may not switch the cloud station.

Step 307: the distribution server receives the first connection response and sends a switching command to the RSP, wherein the switching command comprises the equipment identification of the first terminal equipment and the network identification of the target operator network.

Step 308: and the distribution server sends a second connection response to the first terminal equipment, wherein the second connection response comprises the identification of the target cloud site and is used for indicating the first terminal equipment to switch the cloud site.

Without switching operator networks, i.e. the first connection response does not include the network identification of the target operator network. In this case, if the first connection response includes the station identification of the target cloud station, the distribution server does not send the handover command to the RSP, but continues to send the second connection response to the first terminal device.

In the case of not switching the cloud site, that is, the first connection response does not include the site identification of the target cloud site. In this case, if the first connection response includes the network identification of the target operator network, the distribution server sends the handover command to the RSP, and may continue to send the second connection response to the first terminal device, or stop sending the second connection response to the first terminal device, but the second connection response does not include the content.

Wherein, the description is: the distribution server may send the handover command and the second connection response at the same time, or send the handover command first and then send the second connection response, or send the second connection response first and then send the handover command.

Step 309: and the RSP module receives the switching command, and writes SIM card data belonging to the target operator network into the eSIM of the first terminal equipment according to the switching command.

In this step, the RSP module receives the switching command, extracts the network identifier of the target operator network and the device identifier of the first terminal device from the switching command, obtains SIM card data belonging to the target operator network according to the network identifier of the target operator network, and writes the SIM card data into the eSIM of the first terminal device according to the device identifier of the first terminal device.

The process of writing the SIM card data into the eSIM of the first terminal device by the RSP may be: the RSP correspondingly stores the equipment identification of the first terminal equipment and the SIM card data, and sends a downloading notification to the first terminal equipment according to the equipment identification of the first terminal equipment. And after receiving the download notification, the first terminal device sends a download request to the RSP, wherein the download request comprises the device identifier of the first terminal device. And the RSP acquires the SIM card data corresponding to the equipment identification and sends the SIM card data to the first terminal equipment. And the first terminal equipment receives the SIM card data and stores the SIM card data in the eSIM of the first terminal equipment.

The SIM card data includes at least one of IMSI, key identifier (Ki), Authentication and Key Agreement (AKA), and the like.

Regarding modifying the operator network of the first terminal, in addition to the RSP triggered by the distribution server to write the SIM card data belonging to the target operator network into the eSIM of the first terminal device according to the procedures of steps 306 to 308, other implementation procedures may be adopted.

In a possible implementation manner, the data center server directly triggers the RSP to write the SIM card data to the first terminal device.

In this implementation, the data center server sends a handover command to the RSP, the handover command including the device identification of the first terminal device and the network identification of the target operator network. And the first connection response sent by the data center server to the distribution server does not include the network identification of the target operator network. And the RSP receives the switching command and writes SIM card data belonging to the target operator network into the eSIM of the first terminal equipment according to the switching command.

In another possible implementation manner, the data center server obtains the SIM card data from the RSP, and then triggers the distribution server to write the SIM card data into the first terminal device.

In this implementation, the data center server sends a SIM card acquisition request to the RSP, the SIM card acquisition request including the network identification of the target operator network. The RSP receives the SIM card acquisition request, acquires the SIM card data belonging to the target operator network according to the network identification of the target operator network, and sends an SIM card acquisition response to the data center server, wherein the SIM card acquisition response comprises the SIM card data. And the data center server sends a first connection response to the distribution server, wherein the first connection response comprises the SIM card data. And the distribution server sends a second connection response to the first terminal equipment, wherein the second connection response comprises the SIM card data. And the first terminal equipment receives the second connection response and stores the SIM card data into the eSIM of the first terminal equipment.

Step 310: and the first terminal equipment receives the second connection response, accesses the target operator network according to the SIM card data, and connects the target cloud site through the target operator network according to the site identification of the target cloud site included in the second connection response.

Optionally, the first terminal device establishes a network connection with the target cloud site in the target operator network according to the site identifier of the target cloud site, so as to connect the target cloud site.

In the above process, the first terminal device requests the target operator network and the target cloud site by sending a connection request. In addition to this implementation, the first terminal device may also request the target operator network and the target cloud site by sending two connection requests, which are an eSIM connection request and a site connection request, respectively. When implemented:

the first terminal device transmits an eSIM connection request to the distribution server, the eSIM connection request including a device identification and location information of the first terminal device. The distribution server sends the eSIM connection request to a data center server, the data center server receives the eSIM connection request, a target operator network is determined according to the position information and the acquired data, and SIM card data belonging to the target operator network is written into the eSIM of the first terminal device according to the device identification.

The first terminal device sends a site connection request to the distribution server, wherein the site connection request comprises the device identification and the position information of the first terminal device. The distribution server sends the site connection request to the data center server. The data center server receives the site connection request, determines a target cloud site according to the position information and the acquired data, and sends a site connection response to the distribution server, wherein the site connection response comprises a site identification of the target cloud site. The distribution server transmits the site connection response to the first terminal device.

And the first terminal equipment accesses a target operator network according to the SIM card data, and connects the target cloud site through the target operator network according to the site identification of the target cloud site when receiving the site connection response.

In a case where the first terminal device has accessed the operator network and connected to the cloud site, the first terminal device may transmit only the eSIM connection request when the signal quality of the operator network to which the first terminal device has accessed is poor. In this case, the data center server may determine the target operator from the eSIM connection request and may no longer continue to determine the target cloud site. When obtaining the SIM card data belonging to the target operator, the first terminal device accesses to the target operator network according to the SIM card data, and establishes network connection with the cloud site in the target operator network so as to realize connection to the cloud site in the target operator network with higher signal quality. Or,

in a case where the first terminal device has accessed the operator network and connected to the cloud site, when the network quality of the cloud site to which the first terminal device has connected is poor, the first terminal device may only send the site connection request. In this case, the data center server may determine the target cloud site according to the site connection request, and may not determine the target operator network. When the first terminal device obtains the site identification of the target cloud site, network connection with the target cloud site is established in the accessed operator network according to the site identification, so that connection to the target cloud site with high network quality is achieved.

In the above flow, the distribution server may be integrated with the data center server, so that in the case of integration, the first terminal device directly sends the connection request to the data center server, and the data center server sends the connection response to the first terminal device. That is, the operations of step 303 and step 307 need not be performed.

In step 302, the first terminal device sends a connection request to the data center server. In step 306, the data center server sends a handover command to the RSP, and sends a first connection response to the first terminal device, where the handover command includes a device identifier of the first terminal device and a network identifier of the target operator network, and the first connection response includes a site identifier of the target cloud site.

Under the condition that the distribution server and the data center server are integrated, the data center server can write the SIM card data into the first terminal device in other modes. For example, the data center server obtains SIM card data from the RSP, and sends the SIM card data to the first terminal device. In the implementation of the method, the first and second electrodes are connected,

and the data center server sends an SIM card acquisition request to the RSP, wherein the SIM card acquisition request comprises the network identification of the target operator network. The RSP receives the SIM card acquisition request, acquires the SIM card data belonging to the target operator network according to the network identification of the target operator network, and sends an SIM card acquisition response to the data center server, wherein the SIM card acquisition response comprises the SIM card data. And the data center server sends a first connection response to the first terminal device, wherein the first connection response comprises the SIM card data and the site identification of the target cloud site.

For the first acquired data in step 301, the cloud station acquires the second signal quality of each operator network in each area, and then the data service center averages the second signal quality of each operator network in each area acquired by different cloud stations for each area, to obtain the first signal quality of each operator network in each area, thereby obtaining the first acquired data.

The data center server may acquire the first acquisition data using the operations 3011 to 3014 as follows. The operations 3011 to 3014 are respectively:

3011: the cloud site receives first measurement information sent by second terminal equipment, wherein the first measurement information comprises position information of the second terminal equipment, a network identifier of an operator network and signal strength of the operator network, the second terminal equipment is terminal equipment which is accessed to the cloud site, and the operator network is the operator network which is accessed by the second terminal equipment.

The second terminal device measures the signal strength of an operator network accessed by the second terminal device when accessing the cloud site, and sends first measurement information including the signal strength to the cloud site. Alternatively, after accessing the cloud site, the second terminal device may measure the signal strength of the operator network accessed by the second terminal device periodically or aperiodically and transmit the first measurement information including the signal strength to the cloud site.

The position information of the second terminal device is a coordinate of the second terminal device or an area identifier of a second area, and the second area is an area where the second terminal device is located.

The first measurement information may include only the above listed kinds of information, or the first measurement information may include other information. For example, the first measurement information may further include information such as a device identity of the second terminal device and/or a network type of the operator network.

One operator may have operator networks of different network types, e.g. one operator has one or more of an operator network of a 3G network type, an operator network of a 4G network type, an operator network of a 5G network type, etc.

The device identifier of the second terminal device includes one or more of an integrated circuit card identifier (iccid), an international mobile subscriber identifier (imsi) and an International Mobile Equipment Identifier (IMEI) of the second terminal device.

The area identifier of the second area includes one or more of a cell identifier of a cell in which the second terminal device is located, an area code of a location area in which the second terminal device is located, and the like.

Each terminal device accessed to the cloud site is the same as the second terminal device, acquires the first measurement information, and sends the first measurement information to the cloud site. The cloud station can receive first measurement information sent by different terminal devices in different areas.

3012: and the cloud site acquires the first signal quality of each operator network in each area according to the received first measurement information to obtain third acquisition data.

Optionally, the cloud station may obtain the first signal quality of each operator network in each area through the following operations (1-1) to (1-3). The operations of (1-1) to (1-3) are respectively:

and (1-1) for the second area, the cloud station selects the first measurement information sent by each terminal device in the second area from the received first measurement information.

The cloud site selects the first measurement information including the area identifier of the second area from the received first measurement information to obtain the first measurement information sent by each terminal device in the second area.

When the position information of the second terminal device included in the received first measurement information is a coordinate, the cloud station determines a second area where the second terminal device is located according to the coordinate, and uses the first measurement information as the first measurement information sent by the second terminal device in the second area.

And (1-2) classifying the first measurement information of different operator networks in the first measurement information sent by each terminal device in the second area by the cloud site.

In the first measurement information sent by each terminal device in the second area, the first measurement information including the same network identifier is classified as the first measurement information belonging to the same operator network, so that the first measurement information of the same operator network in the second area is classified into one type.

For example, assuming that the second area is covered by the operator network a and the operator network B, the first measurement information of the operator network a and the first measurement information of the operator network B may be classified from the first measurement information transmitted by each terminal device in the second area.

And (1-3) the cloud site calculates second signal quality of the operator network in a second area according to the signal strength included in each piece of first measurement information of the same operator network.

For example, for the operator network a, an average signal strength is calculated according to the signal strength included in each first measurement information of the operator network a, and the average signal strength is taken as a second signal quality of the operator network a in the second area. Assuming that the second signal quality is 100, a third piece of data is obtained as the second row of data in table 1 below, i.e., the third piece of data includes the area identification area 1 of the second area, the network identification NetIDA of the operator network a and the second signal quality 100.

For the operator network B, an average signal strength is calculated according to the signal strength included in each first measurement information of the operator network B, and the average signal strength is taken as a second signal quality of the operator network B in the second area. Assuming that the second signal quality is 90, a third piece of data is obtained, which is the third row of data in table 1 below, i.e., the third piece of data includes the area identification area 1 of the second area, the network identification NetIDB of the operator network B, and the first signal quality 90.

Optionally, the cloud station acquires the first signal quality of each operator network in different areas by repeatedly performing the operations (1-1) to (1-3), so as to obtain different third data, where the different third data constitutes third acquired data shown in table 1 below.

3013: and the cloud station sends the third acquired data to the data center server.

And for each other cloud site, the operations 3011 to 3013 are respectively executed to send each third collected data to the data center server.

Different terminal devices located in the same area may access different cloud sites, so that different cloud sites may send second signal qualities of different operator networks in the same area. For example, it is assumed that a part of terminal devices in the second area is accessed to the cloud site 1, and the remaining terminal devices in the second area are accessed to the cloud site 2, so that the cloud site 1 can acquire the second signal quality of each operator network in the second area to obtain third acquired data, and send the third acquired data to the data center server. And the cloud site 2 may also acquire the first signal quality of each operator network in the second area to obtain third acquired data, and send the third acquired data to the data center server.

For the third collected data sent by any two cloud stations, for example, still taking the cloud station 1 and the cloud station 2 as an example, there may be one piece of third data (referred to as third data 1) in the third collected data sent by the cloud station 1, there may be one piece of third data (referred to as third data 2) in the third collected data sent by the cloud station 2, and the third data 1 and the third data 2 include the area identifier of the same area and the network identifier of the same operator network, but the second signal quality included in the third data 1 and the second signal quality included in the third data 2 may be the same or may be different.

Optionally, in addition to obtaining the first signal quality of each operator network in different areas through the operations 3011 to 3014, the data center server may also obtain the first signal quality of each operator network in different areas through other manners. For example, each cloud site may send the received first measurement information of the different terminal devices to the data center server. The data center service receives first measurement information of different terminal devices, the first measurement information belonging to the same region and the same operator network is classified into a type of first measurement information from the received first measurement information, an average signal strength is calculated according to the signal strength included in each type of first measurement information, and the average signal strength is used as the first signal quality of the operator network in the region.

When the data center server obtains the first signal quality of each operator network in different areas through the processes of 3111 to 3114, each cloud station directly obtains the second signal quality of each operator network in different areas, and then sends the second signal quality of each operator network in different areas to the data center server, so that the data volume for sending data can be reduced, the occupation of network resources is reduced, the data volume processed by the data center server is also reduced, and the efficiency of obtaining the first signal quality of each operator network in different areas is improved.

For the second acquired data stored in the data center service in step 301, each cloud station first acquires the network quality of the cloud station in each area to obtain second acquired data, and sends the second acquired data to the data center server. And the data center server receives the second acquired data sent by each cloud site and stores the second acquired data of each cloud site.

For example, the cloud station obtains the network quality of the cloud station in area 1 to be 50, and thus obtains a piece of second data, where the piece of second data is the second row of data in table 2, that is, the piece of second data includes the station identifier "ServiceID 1" of the cloud station, the area identifier "area id 1" of area 1, and the network quality of "50". The cloud station acquires that the network quality of the cloud station in the area 2 is 60, and thus obtains a piece of second data, which is the third row of data in the following table 2, that is, the piece of second data includes the station identification "ServiceID 1" of the cloud station, the area identification "area id 2" of the area 2, and the network quality "60".

The second data may comprise only the above listed pieces of information or the second data may comprise further information, e.g. the second data may also comprise a network identification of the operator network.

In a possible implementation manner, the process of the cloud station acquiring the second data may be: and the cloud site classifies second measurement information of different operator networks from second measurement information of each terminal device in the second area.
