The operator network includes each operator network to which all terminal devices connected to the cloud site access.

The distribution server is used to forward data between the terminal device and the data center server.

The data center server is used to determine the carrier network and cloud site that meet the specified conditions based on the data collected by the cloud site.

RSP is used to save SIM card data of each operator's network.

A terminal device is a terminal that requests access, and is used to request access to the operator's network and to connect to cloud sites.

Under this network architecture, the terminal device is connected to the distribution server and sends a connection request to the distribution server.

SIM card data belonging to the target operator's network. The distribution server forwards the site identification to the terminal device. In this way, the terminal device accesses the target operator network according to the SIM card data, and connects to the target cloud site in the target operator network according to the site identifier.

Among them, the following methods can be used to write SIM card data belonging to the target operator network to the terminal device, and the methods are as follows:

Mode 1: The data center server directly triggers the RSP to write SIM card data belonging to the target operator network to the terminal device.

Referring to FIG. 3, an embodiment of the present application provides a method for connecting a cloud site, and the method can be applied to the network architecture shown in FIG. 1, including:

Step 301: The data center server acquires data collected by each cloud site.

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

The collected data includes the first signal quality of each operator network in each area, and the network quality of each cloud site in each area.

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

The first collected data includes at least one piece of first data, and for each piece of first data, the first data includes a network identifier of an operator network, an area identifier of an area, and a first signal quality. The first data is used to describe the first signal quality of the operator network in the area.

The first data may only include the network identifier of the operator's network, the area identifier of the area, and the first signal quality. Alternatively, the first data may further include other information, for example, the first data may further include the network type of the operator's network.

Alternatively, the second data may further include other information, for example, the second data may further include the network identifier of the operator's network, so that the second data is used to describe the cloud site in the area and under the operator's network network quality.

The detailed process of acquiring the collected data by the data center server will be described in detail in the subsequent content, and will not be described here.

For a new terminal device that needs to access a cloud site, the new terminal device needs to be connected to a cloud site through an operator network. For the convenience of the following description, the new terminal device is referred to as the first terminal device. Or, for a terminal device connected to a cloud site, the terminal device has been connected to an operator network, and the terminal device may need to switch to an operator network with higher signal quality in its area or a cloud with higher network quality For the convenience of the following description, the site is also referred to as the terminal device as the first terminal device. The first terminal device is implemented through operations such as steps 302 to 309 .

Step 302: The first terminal device sends a connection request to the distribution server, where the connection request includes the 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, obtains its own location information, and sends a connection request to the distribution server through the network connection.

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

The cell where the first terminal device is located may be the same as or different from the location area where the first terminal device is located. When 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 establishing the network connection by the first terminal device is as follows:

When the first terminal device is a new terminal device that needs to access the cloud site, data of a SIM card belonging to a certain operator network is stored in the first terminal device when the first terminal device leaves the factory. The first terminal device accesses the operator network through the SIM card data, and establishes a network connection with the distribution server in the operator network. Alternatively, the first terminal device is connected to an access point, and a network connection with the distribution server is established through the access point, and the access point may be an access point of a wifi network or a Bluetooth access point or the like.

When the first terminal device is a terminal device that has accessed the operator's network, the first terminal device directly establishes a network connection with the distribution server in the operator's network.

For the location information, the process for the first terminal device to acquire the location information may be:

In the case where the first terminal device is connected to the operator's network, since the operator's network is a network accessed by mobile communication, the first terminal device is located in a cell and a location area in the operator's network, therefore, the first terminal The device obtains the area identifier of the first area in which it is located from the operator's network, or the first terminal device uses the access network element in the operator's network to locate itself to obtain its own coordinates, and the access network element It can be a base station, etc. When the first terminal device is connected to the access point, the first terminal device obtains its own location information by using the access point.

In some embodiments, the first terminal device obtains coordinates of at least three access network elements in the operator's network, and measures the distance between the first terminal device and each of the at least three access network elements. Based on the coordinates of each access network element and the distance between the first terminal device and each access network element, the first terminal device is positioned to obtain the coordinates of the first terminal device.

When the first terminal device accesses the operator's network, the access request may further include the network identifier of the operator's network. And/or, when the first terminal device has been connected to the cloud site, the access request may further include the site identifier of the cloud site.

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

In the case where the location information included in the connection request is a coordinate, the distribution server obtains the area identifier of the first area where the first terminal device is located according to the coordinate, replaces the coordinate included in the connection request with the area identifier, and sends the data to the data The central server sends the connection request. Or, the distribution server does not process the coordinates, and sends the connection request to the data center server, where the connection request including the location information is still the coordinates.

Step 304: The data center server receives the connection request, and determines a target operator network that satisfies the first specified condition according to the location information included in the connection request and the collected data.

The first specified condition includes at least one of an operator network whose signal quality exceeds the first quality threshold, an operator network capable of providing a subscription package for the first terminal device, 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 of the 3041 to 3043 are:

3041: The data center server determines, according to the location information of the first terminal device, an area identifier of the first area where the first terminal device is located.

When the location information included in the connection request is an area identifier, the location information included in the connection request is used as an area identifier of the first area where the first terminal device is located. In the case where the location information included in the connection request is the coordinates, the first area where the first terminal device is located is determined according to the coordinates, and the area identifier of the first area is acquired.

3042: The data center server acquires, according to the area identifier of the first area, the first signal quality of each operator network in the first area.

In 3042, according to the area identifier of the first area, the corresponding network identifiers of each operator's network and the first signal quality of each operator's network in the first area are acquired from the first collected data.

When each piece of first data in the first collected data further includes the network type of the operator's network, according to the area identifier of the first area, the network type of each operator's network can also be obtained from the first collected data.

3043: The data center server determines, according to the first signal quality of the respective operator networks in the first area, an operator network that satisfies the first specified condition as the target operator network.

In 3043, the data center server determines an operator whose first signal quality exceeds the first quality threshold from the acquired network identifiers of each operator's network according to the first signal quality of each operator's network in the first area The network identifier of the network, 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 accesses the target operator network and uses the target operator network to transmit services.

The conditions on which the data center server determines the target operator network may only include the first signal quality of the operator network, or may also include other conditions. For example, in a possible implementation manner, the other conditions include a package subscribed by the first terminal device, that is, the conditions on which the data center server determines the target operator network include the first signal quality and the first signal quality of the operator network and the first A package subscribed by a terminal device. In this example, the process of determining the target operator network may be:

The data center server determines the package subscribed by the first terminal device according to the device identifier of the first terminal device, and determines the network identifier of the operator network that can provide the package from the acquired network identifiers of each operator network, and determines the network identifier of the operator network that can provide the package. Among the network identifiers of the operator networks, the network identifier of an operator network whose first signal quality exceeds the first quality threshold is determined, and the operator network corresponding to the determined network identifier is the target operator network.

Since the determined target operator network can provide the package subscribed by the first terminal device, it is ensured that the first terminal device can use the operator network to transmit services 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, according to the device identifier of the first terminal device, the package identifier subscribed by the first terminal device from package subscription data, where the package subscription data includes at least one subscription Data, for each piece of subscription data, the subscription data includes the device identifier of the terminal device and the package identifier of the package, and the subscription data is used to describe that the terminal device subscribes to the package. The data center server determines the package subscribed by the first terminal device according to the package identifier. Wherein, the subscription data of the package may be stored in the data center server. The user may subscribe to a package for the first terminal device in advance, and there is a piece of subscription data in the package subscription data, and the subscription data includes the device identifier of the first terminal device and the package identifier of the package subscribed for the first terminal device.

Wherein, determining the network identifier of the operator network that can provide the package may include: the package subscribed by the first terminal device may define the network type of the operator network that can provide the package, and in operation 3042, the data center server also obtains the The network type of each operator's network. In 3043, according to the network type of the operator network defined by the package, the network identifier of the operator network capable of providing the package is determined from the network identifiers of the respective operator networks. or,

The data center server obtains the network identifiers of each operator network that can provide the package according to the package identifier of the package subscribed by the first terminal device, the network identifier of each operator network, and the package attribution data. The package attribution data includes at least one piece of attribution data. For each piece of attribution data, the attribution data includes a package identifier of the package and a network identifier of the operator network, and the attribution data is used to describe that the operator network provides the package. The data attributable to the package can be stored in the data center server.

In another possible implementation manner, the other condition further includes the price of the package provided by each operator network, that is, the condition on which the data center server determines the target operator network includes the first signal quality of the operator network , the package subscribed by the first terminal device and the price of the package provided by the operator network. In this example, the process of determining the target operator network may be:

For the operator network that can provide the package, the data center server also obtains the price of each operator network that provides the package, and determines, from the network identifiers of the operator networks that can provide the package, that the quality of the first signal exceeds the first quality threshold And the network identifier of an operator network with the lowest price of the package, and the operator network corresponding to the determined network identifier is the target operator network, so as to determine an operator network whose first signal quality exceeds the first quality threshold and has the lowest cost network identity.

Since the target operator network provides the lowest price of the package subscribed by the first terminal device, in this way, the first terminal device uses the target operator network to transmit services, which can reduce the usage cost.

Optionally, the data center server obtains the price of the package provided by each operator network from the package price data according to the package identifier subscribed by the first terminal device and the network identifier of each operator network. The package price data includes at least one piece of price data. For each piece of price data, the price data includes a package identifier of the package, a network identifier and price of the operator network, and the price data is used to describe the price at which the operator network provides the package.

Step 305: The data center server determines a target cloud site that satisfies the second specified condition according to the location information and the collected data.

The second specified condition includes at least one of a cloud site whose network quality exceeds the second quality threshold, a cloud site with the lowest cost, and the like.

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

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

In the case where each piece of second data in the second collection data includes the area identifier of the area, the site identifier of the cloud site, and the network quality, the data center server obtains the corresponding area identifier from the second collection data according to the area identifier of the first area The site identifier of each cloud site and the network quality of each cloud site in the first area.

In the case where each piece of second data in the second collection data also includes the network identifier of the operator's network, the data center server obtains from the second collection data according to the area identifier of the first area and the network identifier of the target operator's network The corresponding site identifiers of each cloud site and the network quality of each cloud site in the first area and under the target operator network.

3052: The data center server determines, according to the acquired network quality, a target cloud site that satisfies the second specified condition.

In 3052, the data center server determines, from the acquired site identifiers of each cloud site, the site identifier of a cloud site whose network quality exceeds the second quality threshold, and the cloud site corresponding to the determined site identifier is the target cloud site.

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

The conditions on which the data center server determines the target cloud site may only include the network quality of the cloud site, or may also include other conditions. For example, in a possible implementation manner, the other conditions include the service price provided by the cloud site, so in 3052, the data center server obtains the service price provided by each cloud site according to the acquired site identifier of each cloud site; From the acquired site identifiers of each cloud site, the data center server determines the site identifier of the cloud site whose network quality exceeds the second quality threshold and provides the lowest service price, and the cloud site corresponding to the determined site identifier is a cloud site whose network quality exceeds the second quality Threshold and lowest cost target cloud site.

Since the service price 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 for the data center server to obtain the service price provided by each cloud site 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 identifier of each cloud site, and the service price data includes: At least one piece of price data, the price data includes the site identifier of the cloud site and the service price, and the price data is used to describe the service price of the service provided by the site. The service price data may be stored in the data center server.

It should be noted that: the above step 304 may be performed first, and then the step 305 may be performed; or, the step 305 and the step 304 may be performed at the same time; or, the step 305 may be performed first, and then the step 304 may be performed.

Wherein, when acquiring the site identifier of each cloud site in 3051, if the network identifier of the target operator network needs to be used as the acquisition condition, the above step 304 needs to be performed first, and then the step 305 is performed.

Wherein, in the case of performing step 305 first, the data center server needs to first 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 according to the area identifier and the collected data, Determine the target cloud site.

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

In the case that 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 is the same as the target operator network. In the case where it is determined to be different, the connection response includes the network identifier of the target operator network, and the data center server uses the connection response to trigger the first terminal device to switch from the operator network that has been accessed to the target operator network. If it is determined to be the same, the connection response may not include the network identifier of the target operator network, and in this case, the first terminal device may not switch the operator network.

The operation of the data center server to determine whether the operator network to which the first terminal device has accessed and the target operator network are the same may be: in the case that the connection request includes the network identifier of the operator network to which the first terminal device has accessed , the data center server compares the network identification of the operator network that has been accessed with the network identification of the target operator, and if the comparison shows that the two are the same, it is determined that the operator network that the first terminal device has accessed is the same as the target operator network , if the comparison shows that the two are different, it is determined that the operator network to which the first terminal device has accessed is different from the target operator network.

In the case that the first terminal device has been connected to the cloud site, the data center server also determines whether the cloud site to which the first terminal device has been connected is the same as the target cloud site. In the case that it is determined to be different, the connection response includes the site identification of the target cloud site, and the data center server uses the connection response to trigger the first terminal device to switch from the connected cloud site to the target cloud site. If it is determined to be the same, the connection response may not include the site identifier of the target cloud site, and in this case, the first terminal device may not switch the cloud site.

Step 307: The distribution server receives the first connection response, and sends a handover command to the RSP, where the handover command includes the device identifier of the first terminal device and the network identifier of the target operator network.

Step 308: The distribution server sends a second connection response to the first terminal device, where the second connection response includes the identifier of the target cloud site, and is used to instruct the first terminal device to switch the cloud site.

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

It should be noted that: the distribution server may send the switching command and the second connection response at the same time, or send the switching command first and then send the second connection response, or send the second connection response first and then send the switching command.

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

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

Wherein, the process of writing the SIM card data into the eSIM of the first terminal device by the RSP may be as follows: the RSP stores the device identification of the first terminal device and the SIM card data correspondingly, and sends the data to the first terminal device according to the device identification of the first terminal device. The terminal device sends a download notification. After receiving the download notification, the first terminal device sends a download request to the RSP, where the download request includes the device identifier of the first terminal device. The RSP acquires the SIM card data corresponding to the device identifier, and sends the SIM card data to the first terminal device. The first terminal device receives the SIM card data, and saves the SIM card data in the eSIM of the first terminal device.

The SIM card data includes at least one of IMSI, key identifier (Ki) and authentication and key agreement (authentication and key agreement, AKA).

Regarding modifying the operator network of the first terminal, in addition to triggering the RSP 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 process of the above steps 306 to 308, other Implementation process.

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 manner, the data center server sends a handover command to the RSP, where the handover command includes the device identification of the first terminal device and the network identification of the target operator network. However, the first connection response sent by the data center server to the distribution server does not include the network identifier of the target operator network. The RSP receives the handover command, and writes the SIM card data belonging to the target operator network into the eSIM of the first terminal device according to the handover command.

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

In this implementation manner, the data center server sends a SIM card acquisition request to the RSP, where the SIM card acquisition request includes the network identifier of the target operator network. The RSP receives the SIM card acquisition request, acquires SIM card data belonging to the target operator network according to the network identifier of the target operator network, and sends a SIM card acquisition response to the data center server, where the SIM card acquisition response includes the SIM card data. The data center server sends a first connection response to the distribution server, where the first connection response includes the SIM card data. The distribution server sends a second connection response to the first terminal device, where the second connection response includes the SIM card data. The first terminal device receives the second connection response, and saves the SIM card data in the eSIM of the first terminal device.

Step 310: The first terminal device receives the second connection response, accesses the target operator network according to the SIM card data, and connects to the target cloud site through the target operator network according to the site identifier 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 to 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 manner, the first terminal device may also request the target operator network and the target cloud site by sending two connection requests, where the two requests are an eSIM connection request and a site connection request respectively. When implemented:

The first terminal device sends an eSIM connection request to the distribution server, where the eSIM connection request includes the device identification and location information of the first terminal device. The distribution server sends the eSIM connection request to the data center server, and the data center server receives the eSIM connection request, determines the target operator network according to the location information and the collected data, and writes the device identification to the eSIM of the first terminal device. SIM card data belonging to the target operator's network.

The first terminal device sends a site connection request to the distribution server, where the site connection request includes the device identification and location 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 the target cloud site according to the location information and the collected data, and sends the site connection response to the distribution server, where the site connection response includes the site identifier of the target cloud site. The distribution server sends the site connection response to the first terminal device.

The first terminal device accesses the target operator network according to the SIM card data, and when receiving the site connection response, connects to the target cloud site through the target operator network according to the site identifier of the target cloud site.

In the case that the first terminal device has accessed the operator network and is connected to the cloud site, when the signal quality of the operator network to which the first terminal device has accessed is poor, the first terminal device may only send an eSIM connection request. In this case, the data center server may determine the target operator according to the eSIM connection request, and may not continue to determine the target cloud site. When the first terminal device obtains the SIM card data belonging to the target operator, it accesses the target operator network according to the SIM card data, and establishes a network connection with the cloud site in the target operator network, so as to realize the signal Connect to this cloud site in a higher quality target carrier network. or,

In the case that the first terminal device has accessed the operator's network and is connected to the cloud site, when the network quality of the cloud site to which the first terminal device has been connected is poor, the first terminal device may only send a site connection request. In this case, the data center server may determine the target cloud site according to the site connection request, and may determine the target operator network. When the first terminal device obtains the site identification of the target cloud site, according to the site identification, establishes a network connection with the target cloud site in the network of the operator that has been accessed, so as to connect to the target cloud with higher network quality site.

In the above process, the distribution server can be integrated with the data center server, so that in the case of integration, the first terminal device directly sends a connection request to the data center server, and the data center server sends a 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, the handover command includes the device identification of the first terminal device and the network identification of the target operator network, and the first connection response Include the site ID of the target cloud site.

In the case where the distribution server and the data center server are integrated, the data center server may also use other methods to write the SIM card data to the first terminal device. For example, the data center server acquires SIM card data from the RSP, and sends the SIM card data to the first terminal device. When implemented,

The data center server sends a SIM card acquisition request to the RSP, where the SIM card acquisition request includes the network identifier of the target operator network. The RSP receives the SIM card acquisition request, acquires SIM card data belonging to the target operator network according to the network identifier of the target operator network, and sends a SIM card acquisition response to the data center server, where the SIM card acquisition response includes the SIM card data. The data center server sends a first connection response to the first terminal device, where the first connection response includes the SIM card data and the site identifier of the target cloud site.

For the first collected data in step 301, the cloud site first collects the second signal quality of each operator's network in each area, and then the data service center, for each area, collects each operator's network collected by different cloud sites in the The second signal quality in each area is averaged to obtain the first signal quality of each operator network in each area, thereby obtaining the first collected data.

The data center server may acquire the first collected data by using the following operations 3011 to 3014 . The operations of 3011 to 3014 are:

3011: The cloud site receives the first measurement information sent by the second terminal device. The first measurement information includes the location information of the second terminal device, the network identifier of an operator's network, and the signal strength of the operator's network. The second terminal device is The terminal device that has accessed the cloud site, and the operator network is the operator network accessed by the second terminal device.

The second terminal device measures the signal strength of the operator's network to which it is connected 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 periodically or irregularly measure the signal strength of the operator network to which it accesses and send the first measurement information including the signal strength to the cloud site.

The area identifier of the second area includes one or more of the cell identifier of the cell where the second terminal device is located and the area code of the location area where the second terminal device is located.

Like the second terminal device, each terminal device that has been connected to the cloud site acquires the first measurement information, and sends the first measurement information to the cloud site. Therefore, the cloud site can receive the first measurement information sent by different terminal devices in different areas.

3012: The cloud site acquires the second signal quality of each operator network in each area according to the received first measurement information, and obtains third collection data.

The third collection data is used to describe the second signal quality of each operator network on the cloud site in each area, the third collection data includes at least one piece of third data, and each piece of third data includes the area identifier of the area, the operation The network identifier and the second signal quality of the operator network, and the third piece of data is used to represent the second signal quality of the operator network in the area.

Optionally, the cloud site 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:

(1-1) For the second area, the cloud site 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, and obtains the first measurement information sent by each terminal device in the second area.

When the location information of the second terminal device included in the received first measurement information is the coordinates, the cloud site determines the second area where the second terminal device is located according to the coordinates, and uses the first measurement information as the second area in the second area. The first measurement information sent by the terminal device.

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

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, thus classifying the same operator network in the second area The first measurement information within is classified into one category.

For example, assuming that the second area is covered by operator network A and operator network B, in the first measurement information sent by each terminal device in the second area, the first measurement information of operator network A and the operation The first measurement information of the business network B.

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

Assuming that the quality of the second signal is 100, a piece of third data is obtained in this way. The piece of third data is the second row of data in Table 1 below, that is, the piece of third data includes the area identifier AreaID1 of the second area, the operator network A The network identifies NetIDA and the second signal quality 100.

For operator network B, calculate the average signal strength according to the signal strength included in each first measurement information of operator network B, and use the average signal strength as the second signal quality of operator network B in the second area. Assuming that the quality of the second signal is 90, a piece of third data is obtained in this way, which is the third row of data in Table 1 below, that is, the third piece of data includes the area identifier AreaID1 of the second area, the operator network B The network identifies NetIDB and the second signal quality 90.

Optionally, the cloud site repeatedly performs the above operations (1-1) to (1-3) to collect the second signal quality of each operator's network in different areas, so as to obtain different third data, the different third data.

3013: The cloud site sends the third collection data to the data center server.

For each other cloud site, respectively perform the operations of 3011 to 3013 to send the third collection data to the data center server.

Different terminal devices located in the same area may access different cloud sites, so different cloud sites may send second signal qualities of different operator networks in the same area. For example, suppose that some terminal devices in the second area connect to cloud site 1, and the remaining terminal devices in the second area connect to cloud site 2, so that cloud site 1 can collect information about the network of each operator in the second area. The second signal quality in the data center is obtained, the third collected data is obtained, and the third collected data is sent to the data center server. In addition, the cloud site 2 may also collect the first signal quality of each operator's network in the second area, obtain the third collection data, and send the third collection data to the data center server.

The first signal quality of each operator network in each area is acquired in the same manner as described above, thereby obtaining different first data, and the different first data constitutes the first collected data.

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

Wherein, when the data center server obtains the first signal quality of each operator's network in different areas through the process of 3111 to 3114, since each cloud site directly obtains the second signal quality of each operator's network in different areas, Then, the second signal quality of each operator's network in different areas is sent to the data center server, which can reduce the amount of data sent, reduce the occupation of network resources, and also reduce the amount of data processed by the data center server. The efficiency of obtaining the first signal quality of each operator's network in different areas is improved.

For the second collection data stored in the data center service in step 301, each cloud site first collects its network quality in each area, obtains the second collection data, and sends the second collection data to the data center server. The data center server receives the second collection data sent by each cloud site, and stores the second collection data of each cloud site.

For the network quality of each cloud site in each region, the cloud site may collect the network quality of the cloud site in each region through the following operations 3111 to 3113 . The operations of 3111 to 311 are:
