Description

Operator identification method and device and internet access system

Technical Field

The embodiment of the invention relates to the field of internet, in particular to an operator identification method, an operator identification device and an internet access system.

Background

With the continuous development of internet technology, internet access becomes more and more convenient. After a user accesses a terminal to a WiFi (Wireless-Fidelity) network, internet access can be performed through various applications in the terminal.

In order to save access traffic and prevent hijacking of operators, terminals typically use a proxy approach for internet access. When the internet access is performed in the proxy mode, the terminal sends a proxy IP (internet protocol) acquisition request to the background server, and the background server allocates a corresponding proxy IP address to the terminal after receiving the request, so that the terminal can access the proxy server according to the proxy IP address, and thus network resources are acquired from a corresponding network resource server by means of the proxy server. And in order to ensure the access speed, the proxy IP address allocated by the background server and the WiFi network currently accessed by the terminal should belong to the same operator.

Operators providing the WiFi network may be divided into a large operator and a small operator, wherein the large operator refers to an operator having an AS (Autonomous System) number, and such an operator has a dedicated IP segment; the small operator is an operator without an AS number and an exclusive IP section, and the operator rents a network of the large operator to provide the internet access service for the terminal.

In the prior art, no matter the terminal accesses the WiFi network provided by the large operator or the small operator, the background server allocates a corresponding proxy IP address to the terminal according to the operator to which the current WiFi network belongs. However, in the operation process, a small operator switches the operator and the network according to its own policy (for example, the load condition of a large leased operator), which causes the proxy IP address allocated by the background server to be different from the operator to which the WiFi network belongs, and then causes the problem of cross-operator access, affects the internet quality, and even causes access interruption.

Disclosure of Invention

In order to solve the problem that in the prior art, a small operator can switch the operator and a network according to own strategies in the operation process, so that the proxy IP address distributed by a background server is different from the operator to which a WiFi network belongs, cross-operator access is generated, the internet quality is influenced, and even the access is interrupted, the embodiment of the invention provides an operator identification method, an operator identification device and an internet access system.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the prior art, when a terminal performs internet access in a proxy manner, a resource acquisition request is not directly sent to a network resource server, but a proxy IP address is requested to be allocated to a background server (a server corresponding to an application program performing internet access), a resource acquisition request is sent to the proxy server according to the allocated proxy IP address, the proxy server acquires a network resource from a corresponding network resource server according to the resource acquisition request, and finally the acquired network resource is returned to the terminal. Because the proxy server has the functions of resource caching and advertisement filtering, the access flow can be saved by using a proxy mode to access the Internet, and the hijacking of the operator caused by adding advertisement links to the webpage by the operator is prevented. Meanwhile, in order to ensure the access speed, the proxy IP address allocated by the background server and the WiFi network currently accessed by the terminal should belong to the same operator, for example, the WiFi network currently accessed by the terminal belongs to the telecommunications, and the proxy IP address allocated by the background server should also belong to the telecommunications.

When the terminal accesses the WiFi network provided by the large operator and performs internet access, the operator and the network cannot be switched due to the fact that the large operator has the fixed AS number, and therefore the proxy IP address distributed by the background server is always consistent with the operator to which the WiFi network belongs, and the problem of cross-operator access does not exist.

However, when the terminal accesses the WiFi network provided by the small operator, because such an operator may switch the operator and the network according to its own policy (for example, network load conditions of each leased operator), the operator corresponding to the WiFi network is continuously switched during the internet access process, and the switching process cannot be perceived by the terminal. When the operator is switched, the terminal still uses the previously allocated proxy IP address to access the internet, which causes the problem of cross-operator access, affects the access speed, and even causes access interruption.

For example, the terminal accesses small operator a, and small operator a leases the networks of large operators B, C and D. When the terminal accesses the small operator A, the small operator A allocates a network of a large operator B for the terminal, and the terminal accesses the Internet according to the proxy IP address B (matched with the large operator B) allocated by the background server. However, in the access process, the small operator a switches the network to which the terminal accesses to the network corresponding to the large operator C according to the network load condition of the large operator B, C, D, and the network switching process is executed by the small operator a, so that the terminal cannot sense the network switching process. If the terminal still uses the proxy IP address b to access the internet, since the operator corresponding to the proxy IP address b is different from the large operator C to which the terminal is currently accessed, cross-operator access will occur.

In order to solve the above problems, in the embodiment of the present invention, the background server establishes a mapping relationship between the BSSID and the operator, identifies, according to a current operator corresponding to the WiFi network accessed by the terminal, the WiFi network provided by the small operator by detecting whether the operator corresponding to the same BSSID changes, and further formulates a corresponding access policy for the terminal accessed to such WiFi network according to the identification result, thereby avoiding the problems of cross-operator access and the like.

Referring to fig. 1, a schematic structural diagram of an internet access system according to an embodiment of the present invention is shown. The internet access system comprises a terminal 110, a background server 120, at least one proxy server 130 and a network resource server 140, wherein the terminal 110 is respectively connected with the background server 120, the proxy server 130 and the network resource server 140 through a WiFi network provided by an operator.

The terminal 110 is an electronic device having a WiFi connection function, and the electronic device may be a smart phone, a tablet computer, a portable personal computer, or the like. An application program with an internet access function is installed in the terminal 110, and after the terminal 110 accesses the WiFi network, internet access can be performed through the application program. The application program may be a browser application program, an instant messaging application program, a video playing application program, and the like.

The backend server 120 is a backend server of the application program in the terminal 110, and is configured to make a corresponding access policy for the terminal when accessing the internet through the application program. Taking the access policy as an example of allocating the proxy IP address, when the terminal 110 uses the browser application to access the internet, the background server 120 of the browser application allocates the proxy IP address to the terminal 110 according to the operator to which the current access network of the terminal 110 belongs, and instructs the terminal 110 to access through the proxy IP address, thereby avoiding hijacking of the operator.

The proxy server 130 is configured to provide a proxy service for the terminal accessing the internet, and when the terminal 110 accesses the internet through the proxy server 130, the proxy server 130 obtains a network resource from the corresponding network resource server 140 or from a local cache according to a resource obtaining request sent by the terminal 110, and returns the network resource to the terminal 110. The proxy server 130 also has functions of advertisement filtering, etc. for processing the acquired network resources, thereby providing access quality.

In order to adapt to different types of operators, a plurality of proxy servers 130 are arranged in the internet access system, and different proxy servers 130 correspond to different operators; when the background server 120 allocates the proxy server 130 to the terminal, the matched proxy server 130 is allocated to the terminal according to the operator to which the terminal 110 is accessed, so that cross-operator access is avoided.

The proxy server 130 and the network resource server 140 are connected through a wired network or a wireless network.

The network resource server 140 is used for providing network resources for the terminal, and the network resource server 140 may be a web server, a multimedia server, or a mail server, etc. When the terminal 110 performs internet access in a proxy manner, the network resource server 140 provides corresponding network resources to the terminal 110 through the proxy server 130; when the terminal 110 performs internet access in a direct connection manner, the network resource server 140 directly returns corresponding network resources to the terminal 110 according to the resource acquisition request of the terminal 110.

The embodiments of the present invention are described by taking the example that the operator identification method is used in the backend server 120 shown in fig. 1.

Referring to fig. 2A, a flowchart of an operator identification method according to an embodiment of the present invention is shown, where the operator identification method is used in the backend server 120 shown in fig. 1 for an example to explain, the method includes:

step 201, acquiring BSSID and gateway IP address of the terminal accessing the WiFi network.

Optionally, the BSSID and the gateway IP address are obtained by the background server from WiFi connection information sent by the terminal, and further, the WiFi connection information is sent to the background server corresponding to the application program when the terminal accesses the WiFi network and starts the application program; or the like, or, alternatively,

the WiFi connection information is sent to a background server of the application program when the terminal detects that the network connection mode changes (namely, the terminal is switched from one WiFi network to another WiFi network or from a mobile data network to the WiFi network) in the Internet access process through the application program; or the like, or, alternatively,

the WiFi connection information is periodically sent to a background server according to a preset reporting period of an application program in the process that the terminal accesses the Internet through the application program.

Optionally, when the terminal is connected to the WiFi network through the routing device, the BSSID is a Media Access Control (MAC) address of the routing device.

For example, when the terminal accesses a WiFi network provided by the routing device, the terminal obtains the MAC address of the routing device as 1A:23:3D:4A:0F:1F, and adds the MAC address as the BSSID of the WiFi network to the WiFi connection information, and correspondingly, the background server obtains the BSSID included in the WiFi connection information as 1A:23:3D:4A:0F: 1F.

Step 202, determining a current operator corresponding to the WiFi network according to the gateway IP address.

Optionally, when the background server obtains the gateway IP address according to the WiFi connection information sent by the terminal, because the terminal sends the WiFi connection information through the WiFi network, when the background server receives the WiFi connection information, the current gateway IP address of the WiFi network can be obtained, an operator to which the gateway IP address belongs is determined, and the determined operator is further determined as the current operator corresponding to the WiFi network.

Step 203, searching a historical operator corresponding to the WiFi network in a pre-stored mapping relationship according to the BSSID, where the pre-stored mapping relationship is used to indicate a mapping relationship between each BSSID and each operator.

Optionally, the pre-stored mapping relationship is generated according to historical WiFi connection information sent by each terminal.

When the WiFi network is provided by a large operator, the operator to which the WiFi network corresponds will remain unchanged (i.e., the operator to which the BSSID corresponds remains unchanged); when the WiFi network is provided by a small operator, the operator corresponding to the WiFi network may also change (i.e., the operator corresponding to the BSSID changes) because the small operator may perform handover on the network. Therefore, according to the above characteristics, the background server can determine whether the WiFi network corresponding to the BSSID is provided by a small operator by detecting whether the operator corresponding to the BSSID changes.

Optionally, when the BSSID appears for the first time, the background server stores the mapping relationship between the BSSID and the operator; when the BSSID is obtained again, the background server searches the historical operator corresponding to the BSSID from the pre-stored mapping relation. .

Illustratively, the mapping relationship between the BSSID and the operator in the pre-stored mapping relationship is shown in table one.

Watch 1

BSSID	Operator
		10:2D:3E:49:51:6C	Operator A
1F:3A:5C:7B:9F:0F	Operator B
		2F:4C:6B:8A:09:0F	Operator A
1A:23:3D:4A:0F:1F	Operator C

And step 204, identifying whether the WiFi network belongs to a small operator according to the current operator and the historical operator, wherein the small operator refers to an operator without an AS number.

When the historical operator corresponding to the BSSID is found out from the pre-stored mapping relation, the background server identifies whether the current operator and the historical operator of the WiFi network corresponding to the BSSID are changed or not, and further determines whether the WiFi network belongs to a small operator or a large operator according to an identification result.

In one possible embodiment, as shown in fig. 2B, this step includes the following steps.

Step 204A, detecting whether the current operator is consistent with the historical operator.

The background server detects whether a current operator corresponding to the BSSID is consistent with a historical operator, and when the current operator is consistent with the historical operator, the background server determines that the WiFi network corresponding to the BSSID is provided by a large operator; when the BSSID is inconsistent with the BSSID, the background server determines that the WiFi network corresponding to the BSSID is provided by the small operator.

And step 204B, if the current operator is not consistent with the historical operator, determining that the WiFi network belongs to a small operator.

When the current operator corresponding to the BSSID is inconsistent with the historical operator, the background server determines that the terminal is currently accessed to the WiFi network provided by the small operator, namely the WiFi network corresponding to the BSSID is provided by the small operator.

The background server can identify not only a large operator with an AS number but also a small operator without the AS number through the operator identification mechanism; further, the background server can make corresponding access strategies for the terminal aiming at different types of operators, and the internet access quality of the terminal is ensured. For example, when the terminal accesses a WiFi network provided by a small operator and requests to obtain an agent IP address, the background server instructs the terminal to access the internet in a direct connection manner without accessing through the agent server, thereby avoiding the problem of cross-operator access caused by network switching of operators.

In an actual application process, when the routing device is used to provide a WiFi network, an operator corresponding to the BSSID may also be changed due to a change of an operator connected to the routing device (for example, the routing device is connected to a modem of a different operator), and at this time, if the operator identification is performed only according to whether the operator corresponding to the BSSID is changed (that is, the operator identification manner in

steps

204A and 204B is adopted), an operator identification error may be caused. In order to further improve the accuracy of the operator identification, in a possible manner, the backend server performs the operator identification by using the operator change condition and the operator change frequency as the basis, and the following description uses an exemplary embodiment.

Referring to fig. 3A, a flowchart of an operator identification method according to another embodiment of the present invention is shown, where the operator identification method is used in the backend server 120 shown in fig. 1 for an example to explain, the method includes:

step 301, receiving WiFi connection information sent by a terminal, where the WiFi connection information includes BSSID of a WiFi network accessed by the terminal.

Optionally, when the terminal accesses the WiFi network and starts the application program to access the internet, the terminal obtains the BSSID of the access WiFi network and sends WiFi connection information containing the BSSID to the background server corresponding to the application program. Correspondingly, the background server receives WiFi connection information sent by the terminal and acquires BSSID contained in the WiFi connection information.

Step 302, acquiring a gateway IP address when the terminal sends the WiFi connection information.

Because the WiFi connection information is sent by the terminal through the WiFi network, the background server can acquire the gateway IP address when the terminal sends the WiFi connection information while receiving the WiFi connection information.

Optionally, when the WiFi connection information is sent in the form of a TCP/IP packet, the background server determines a source IP address in the TCP/IP packet as a gateway IP address.

For example, the gateway IP address when the backend server acquires that the terminal sends the WiFi connection information is 101.0.2.214.

Step 303, according to the gateway IP address, searching an operator corresponding to the gateway IP address in an IP library, where the IP library includes a corresponding relationship between the operator having the AS number and the IP segment.

The background server stores an IP library in advance, and the IP library comprises a corresponding relation between an operator (namely a large operator) with an AS number and each IP section. Illustratively, the correspondence between the operators and the IP segments is shown in table two.

Watch two

Operator	IP section
		Operator A	101.0.0.0-101.0.3.255
Operator B	112.64.0.0-112.65.255.255
		Operator C	113.112.0.0-113.119.255.255

After the background server acquires the gateway IP address, the IP section to which the gateway IP address belongs is searched in the IP library, and the operator to which the searched IP section belongs is further determined.

For example, the gateway IP address obtained by the background server is 101.0.2.214, and the IP segment to which the gateway IP address belongs is found in the IP library to be 101.0.0.0-101.0.3.255, and the IP segment belongs to the operator a, that is, the background server determines the operator a as the operator corresponding to the gateway IP address.

And step 304, determining the found operator as the current operator corresponding to the WiFi network.

Further, since the BSSID of the WiFi network does not change, the background server determines the operator corresponding to the gateway IP address as the current operator corresponding to the BSSID.

Optionally, the background server stores the BSSID in association with the current operator.

Optionally, in order to avoid that the subsequent operator identification is affected by an illegal BSSID in the WiFi connection information, the background server further needs to perform validity identification on the BSSID, and filter the identified illegal BSSID.

In a possible implementation manner, the background server performs validity detection on the BDDIS through a preset regular expression. For example, when the BSSID is a MAC address, the backend server detects whether the MAC address is legal or not by using a regular expression "[ 0-9a-fA-F ] {2}) ([/\ s: ] [0-9a-fA-F ] {2}) {5}) $".

Step 305, searching a historical operator corresponding to the WiFi network in a pre-stored mapping relationship according to the BSSID, where the pre-stored mapping relationship is used to indicate a mapping relationship between each BSSID and each operator.

After the current operator corresponding to the BSSID is determined, the background server further searches whether a historical operator corresponding to the BSSID exists in a pre-stored mapping relation.

If the historical operator corresponding to the BSSID is found, the background server further determines whether the operator corresponding to the BSSID is changed according to the current operator and the historical operator, and performs the following step 306.

If the historical operator corresponding to the BSSID is not found, the background server stores the BSSID (as a key) and the corresponding operator (as a value) into the pre-stored mapping relation.

Optionally, in order to determine a change frequency of the operator when the BSSID changes corresponding to the operator, the pre-stored mapping relationship further includes a recording time corresponding to each mapping relationship. Accordingly, when the mapping relationship between the BSSID and the operator is stored, it is necessary to associate and store the recording time of the mapping relationship. Illustratively, the correspondence among the BSSID, the operator, and the recording time in the pre-stored mapping relationship is shown in table three.

Watch III

BSSID	Operator	Recording time of day
			10:2D:3E:49:51:6C	Operator A	2016/11/10 10:15:20
1F:3A:5C:7B:9F:0F	Operator B	2016/11/10 10:15:50
			2F:4C:6B:8A:09:0F	Operator A	2016/11/10 10:19:30
1A:23:3D:4A:0F:1F	Operator C	2016/11/10 10:21:25

Step 306, a first recording time of the current operator and a second recording time of the historical operator are obtained.

Different from the embodiment shown in fig. 2B, when the background server identifies the operator to which the terminal is accessed, a first recording time corresponding to the current operator and a second recording time corresponding to the historical operator need to be obtained, where the first recording time and the second recording time are times when the background server records the mapping relationship between the BSSID and the operator.

For example, the background server obtains the first recording time corresponding to the current operator as 2016/11/1020:21:25, and obtains the second recording time corresponding to the historical operator as 2016/11/1010:21:25 from the pre-stored mapping relationship shown in table three.

Step 307, detecting whether the current operator is consistent with the historical operator, and whether the time interval between the first recording time and the second recording time is greater than a preset time length.

Different from the embodiment shown in fig. 2B, when detecting whether the current operator and the historical operator are consistent, the background further needs to calculate a time interval between the first recording time and the second recording time according to the obtained first recording time and the obtained second recording time, and detect whether the time interval is greater than a preset time length. For example, the preset time period may be 24 h.

Optionally, when the current operator is consistent with the historical operator, it is indicated that the operator corresponding to the same BSSID is not changed, the background server determines that the WiFi network currently accessed by the terminal is provided by the operator having the AS code, and updates the recording time corresponding to the BSSID in the pre-stored mapping relationship to the first recording time.

When the current operator is not consistent with the historical operator, and the time interval between the first recording time and the second recording time is less than the preset time, the background server determines that the WiFi network currently accessed by the terminal is provided by the operator without the AS code, and executes the following step 308.

When the current carrier and the historical carrier are not consistent, and the time interval between the first recording time and the second recording time is longer than the preset time, the background server temporarily fails to determine the carrier providing the WiFi network, and the following step 310 is executed.

And 308, if the current operator is inconsistent with the historical operator and the time interval is less than the preset time, determining that the WiFi network belongs to the small operator.

When the current operator is inconsistent with the historical operator, and the time interval between the first recording time and the second recording time is less than the preset time, the background server determines that the operator corresponding to the BSSID changes, and the frequency of the change is high, so that the WiFi network corresponding to the BSSID is provided by a small operator.

Step 309, setting a corresponding predetermined identifier for the BSSID, where the predetermined identifier is used to indicate that the WiFi network corresponding to the BSSID is provided by the small operator.

Further, when the background server determines that the WiFi network corresponding to the BSSID is provided by the small operator, the background server sets a corresponding predetermined identifier for the BSSID. And when other subsequent terminals are connected to the WiFi network corresponding to the BSSID and send WiFi connection information to the background server, the background server can directly determine that the terminal is accessed to the WiFi network provided by the small operator according to the preset identifier.

And 310, if the current operator is inconsistent with the historical operator and the time interval is greater than the preset time, updating the historical operator according to the current operator, and updating the second recording time according to the first recording time.

And when the current operator is not consistent with the historical operator, but the time interval between the first recording time and the second recording time is longer than the preset time, the background server determines that the operator corresponding to the BSSID changes, but the change frequency is lower. In this case, the background server updates the historical operator only according to the current operator of the BSSID, updates the second recording time of the historical operator according to the first recording time of the current operator, and does not determine the type of the operator.

Optionally, if the WiFi connection information including the BSSID is received again subsequently, and it is detected that the current operator of the BSSID is consistent with the historical operator corresponding to the BSSID in the pre-stored mapping relationship, the background server determines that the previous operator change is caused by a change of an operator connected to the routing device, and determines that the WiFi network corresponding to the BSSID is provided by a large operator; and if the WiFi connection information containing the BSSID is subsequently received again, and the current operator of the BSSID is detected to be inconsistent with the historical operator corresponding to the BSSID in the pre-stored mapping relation, the background server determines that the WiFi network corresponding to the BSSID is provided by the small operator, and sets corresponding preset identification for the BSSID.

In the embodiment, in order to improve the accuracy of operator identification, the background server identifies the operator by using the operator change condition and the operator change frequency as identification bases, and determines that the WiFi network corresponding to the BSSID is provided by a small operator when the operator is changed and the operator change frequency is high, so that misidentification caused by the change of the operator connected to the routing device is avoided.

In the prior art, a background server cannot identify large and small operators, and only allocates corresponding proxy IP addresses for the operators according to the current gateway IP address of a terminal; when a terminal using a small operator to provide a WiFi network carries out Internet access according to an agent IP address distributed by a background server, the distributed agent IP address cannot be kept consistent with an operator in real time due to the fact that the small operator can switch the network, and then the problem of cross-operator access is caused; in the embodiment of the present invention, since the background server can identify the small operator through the steps 301 to 310, when the terminal accessing the small operator requests the proxy IP address, the background server can make a corresponding access policy for the terminal, thereby avoiding cross-operator access. An exemplary embodiment is described below.

On the basis of fig. 3A, as shown in fig. 3B, it shows a method flowchart of an operator identification method provided by another embodiment of the present invention. In this embodiment, a process of allocating an agent IP address to a terminal according to an agent IP acquisition request sent by the terminal after the method is applied to a background server to identify a WiFi network corresponding to a small operator is described as an example, the method includes:

step 311, the terminal sends a proxy IP acquisition request to the background server, where the proxy IP acquisition request includes BSSID for acquiring a proxy IP address.

When an application program in the terminal needs to access the internet through the proxy server, the terminal sends a proxy IP acquisition request to a background server corresponding to the application program, and requests the background server to distribute a proxy IP address. Different from the prior art, the proxy IP acquisition request sent by the terminal carries the BSSID of the WiFi network which is accessed currently, so that the background server can identify the operator to which the WiFi network accessed currently by the terminal belongs according to the BSSID.

In step 312, the background server receives the proxy IP acquisition request sent by the terminal.

Correspondingly, the background server receives the proxy IP acquisition request sent by the terminal and acquires the BSSID carried in the proxy IP acquisition request.

Step 313, the background server detects whether the BSSID corresponds to a predetermined identifier.

After the background server obtains the BSSID, the background server determines an operator to which the terminal is currently accessed to the WiFi network according to the BSSID. In step 309, the BSSID corresponding to the small operator is set with the corresponding predetermined identifier, so that the background server can determine whether the terminal currently accesses the WiFi network and belongs to the small operator by detecting whether the BSSID corresponds to the predetermined identifier.

When detecting that the BSSID contains the corresponding predetermined identifier, the background server determines that the WiFi network currently accessed by the terminal belongs to a small operator, and performs the following step 314; when detecting that the BSSID does not contain the corresponding predetermined identifier, the background server determines that the WiFi network currently accessed by the terminal belongs to the large operator, and performs step 316 described below.

Step 314, if the BSSID corresponds to a predetermined identifier, the background server issues a direct connection identifier to the terminal.

When detecting that the BSSID corresponds to a preset identifier, the background server determines that the terminal is currently accessed to a WiFi network provided by a small operator, in order to avoid cross-operator access caused by network switching of the small operator, the background server issues a direct connection identifier to the terminal sending the proxy IP acquisition request, and instructs the terminal to stop adopting a proxy IP address to carry out internet access and adopt a direct connection mode to carry out internet access.

Optionally, when detecting that the BSSID corresponds to the predetermined identifier, the background server may further send a timing report instruction to the terminal, and instruct the terminal to report the connection information at a timing. When receiving the connection information reported by the terminal, the background server can reallocate the proxy IP address for the terminal according to the gateway IP address when the terminal sends the connection information, so that the proxy IP address and the network currently accessed by the terminal belong to the same operator, and the reallocation mechanism is utilized to relieve the problem of cross-operator access to a certain extent.

And 315, the terminal stops adopting the proxy IP address to access the Internet according to the direct connection identifier issued by the background server.

Correspondingly, the terminal receives the direct connection identification issued by the background and performs internet access in a direct connection mode. Because the terminal does not perform internet access through the proxy IP address any more, the problem that the proxy IP address is not matched with the current operator does not exist, and cross-operator access is avoided.

Optionally, after receiving the direct connection identifier, the terminal stores the BSSID of the current WiFi network in association with the direct connection identifier, and when subsequently connecting to the WiFi network corresponding to the BSSID, the terminal directly accesses the internet by using a direct connection method, and does not need to send an agent IP acquisition request to a backend server.

Step 316, if the BSSID does not have the corresponding predetermined identifier, the background server allocates an agent IP address to the terminal according to the operator corresponding to the BSSID.

And when detecting that the BSSID does not have a corresponding preset identifier, the background server determines that the terminal is currently accessed to a WiFi network provided by a large operator, and in order to improve the access quality of the terminal, the background server allocates an agent IP address to the terminal according to the operator corresponding to the BSSID.

Optionally, the background server searches for an operator corresponding to the BSSID from a pre-stored mapping relationship, or the background server determines the operator corresponding to the BSSID according to a gateway IP address when the terminal sends the proxy IP acquisition request.

And step 317, the terminal accesses the internet according to the distributed proxy IP address.

Correspondingly, the terminal accesses the corresponding proxy server according to the proxy IP address distributed by the background server and acquires the network resource from the network resource server through the proxy server, thereby achieving better access quality by virtue of the resource caching and advertisement filtering functions of the proxy server.

In this embodiment, when the background server receives an agent IP acquisition request sent by the terminal, the background server identifies an operator to which the terminal currently accesses the WiFi network according to BSSID carried in the agent IP acquisition request, and when the terminal is identified to access the WiFi network provided by a small operator, the background server instructs the terminal to perform internet access in a direct connection manner, thereby avoiding cross-operator access caused by network switching performed by the operator.
