In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The international mobile subscriber identity obtaining method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the gateway 104 via a network, and the gateway 104 communicates with the server 106 via the network. The terminal 102 may be, but is not limited to, a smart phone and a tablet computer, the gateway 104 is a device for implementing network interconnection, and the server 106 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, an international mobile subscriber identity obtaining method is provided, which is described by taking the method as an example applied to the server 106 in fig. 1, and includes the following steps:
The terminal access request is generated by inserting an international mobile subscriber identity corresponding to the terminal into an identity acquisition request after the gateway receives the identity acquisition request sent by the terminal. The identification code acquisition request is a request for access to the server transmitted by the terminal.
Specifically, the terminal generates an identification code acquisition request, and sends the identification code acquisition request to the server through the operator network. When the identification code acquisition request passes through the gateway, the gateway inserts the international mobile subscriber identification code corresponding to the terminal into the identification code acquisition request to generate a terminal access request. The gateway sends the terminal access request to the server, and the server receives the terminal access request sent by the gateway.
In one embodiment, when the terminal detects that the user uses the third-party application or accesses the third-party link, the terminal triggers an interface calling instruction, and obtains the international mobile subscriber identity to acquire interface information according to the interface calling instruction. The terminal generates an identification code acquisition request according to the international mobile subscriber identification code acquisition interface information, and sends the identification code acquisition request to the gateway through the operator network.
For example, when the terminal detects that the user uses the third-party application, the terminal triggers an interface call instruction, and obtains the international mobile subscriber identity acquisition interface information according to the interface call instruction, where the international mobile subscriber identity acquisition interface may be at least one of an http interface and an https interface. HTTP (HyperText Transfer Protocol) is a network Protocol most widely used on the internet, and HTTPs (HyperText Transfer Protocol over secure Socket layer) is an HTTP channel aiming at security and is a security version of HTTP. The terminal generates an identification code acquisition request according to the international mobile subscriber identification code acquisition interface information, and sends the identification code acquisition request to the gateway through the 4G network of the operator A.
Specifically, after the server acquires the terminal access request, the server analyzes the terminal access request to obtain an international mobile subscriber identity cipher text, a gateway network address and a terminal network address. The server decrypts the international mobile subscriber identity cipher text to obtain the international mobile subscriber identity, and determines the network identifier according to the gateway network address and the terminal network address.
And step 206, verifying the extracted network identification through the access right verification list.
Wherein the access right verification list is a list storing network identifications that can access the server.
Specifically, after the server acquires the network identifier, the server reads the access authority verification list, and verifies the extracted network identifier through the access authority verification list. The server inquires the extracted network identification in the access authority verification list, if the network identification is inquired, the server confirms that the terminal access request is from a gateway of a specified operator, and determines that the international mobile subscriber identification code extracted from the terminal access request is valid; if the network identification is not inquired, the server determines that the international mobile subscriber identity extracted from the terminal access request is invalid.
For example, the server is a server of an operator a, when the server queries a network identifier in the access authority list, it is determined that the terminal access request is from a gateway of the operator a, and it is determined that the international mobile subscriber identity extracted from the terminal access request is valid; when the server does not inquire the network identification, the terminal access request is confirmed not to come from the gateway of the operator A, and the international mobile subscriber identity extracted from the terminal access request is determined to be invalid.
And step 208, when the access authority verification list passes the verification of the extracted network identification, sending the extracted international mobile subscriber identity to the terminal.
Specifically, when the server queries the network identifier in the access right verification list, the network identifier is verified to be passed, the server acquires the extracted international mobile subscriber identity, and returns the international mobile subscriber identity to the terminal.
In one embodiment, the server resolves the international mobile subscriber identity into a JSON string and then sends the JSON string representing the international mobile subscriber identity to the terminal. And after receiving the international mobile subscriber identity sent by the server, the terminal sends the received international mobile subscriber identity to the third-party server.

The gateway network Address and the terminal network Address may be IP addresses (internet protocol addresses) of the gateway and the terminal.
Specifically, after the server acquires the terminal access request, the server analyzes the terminal access request to obtain an international mobile subscriber identity, a gateway network address and a terminal network address in the terminal access request.
In step 304, the same portion of the gateway network address and the terminal network address is determined.
Specifically, the server reads each segment of the gateway network address and the terminal network address, performs comparative analysis, and takes the same segment of the gateway network address and the terminal network address as the same part.
And step 306, obtaining the network identification according to the determined identical part.
The network identifier is the unique identifier of the network to which the terminal and the gateway belong.
Specifically, after determining the same parts of the gateway network address and the terminal network address, the server obtains the network identifier from the determined same parts according to the specified format of the network identifier.
For example, the extracted gateway network address is 169.254.8.128, the extracted terminal network address is 169.254.8.1, the same part of the gateway network address and the terminal network address is 169.254.8, the network identifier is composed of 32-bit binary digits, and the network identifier is 169.254.8.0 from the determined same part.

As shown in fig. 4, in an embodiment, the step 302 further includes a step of obtaining an international mobile subscriber identity, where the step includes the following steps:
The identification code ciphertext is a ciphertext obtained by encrypting the international mobile subscriber identification code by the gateway.
Specifically, after receiving the terminal access request, the server triggers an analysis instruction, and analyzes the terminal access request according to the analysis instruction to obtain an identification code ciphertext, a gateway network address and a terminal network address in the terminal access request.
Specifically, the server analyzes the terminal access request to obtain an identification code ciphertext, then queries a pre-stored decryption key for decrypting the identification code ciphertext from the database, and extracts the queried decryption key.
In one embodiment, after the server analyzes the terminal access request to obtain the identification code ciphertext, the server extracts the ciphertext identifier of the identification code ciphertext, queries the extracted ciphertext identifier in a decryption key list, and extracts a decryption key corresponding to the ciphertext identifier.
And 406, decrypting the identification code ciphertext according to the inquired decryption key to obtain the international mobile subscriber identification code.
Specifically, after the server queries the decryption key corresponding to the identification code ciphertext, the identification code ciphertext is decrypted through the decryption key, and the international mobile subscriber identification code is obtained.
In the embodiment, the terminal access request is analyzed to obtain the identification code ciphertext, the decryption key corresponding to the identification code ciphertext is inquired, the identification code ciphertext is decrypted according to the inquired decryption key to obtain the international mobile subscriber identity, and the security for obtaining the international mobile subscriber identity is improved.
As shown in fig. 5, in an embodiment, the step of generating the terminal access request specifically includes the following steps:
Specifically, the terminal sends an identification code acquisition request to the gateway through the operator network, and the gateway receives the identification code acquisition request sent by the terminal.
Specifically, the gateway analyzes the identification code acquisition request to obtain identification code acquisition request information, and extracts the terminal identifier from the identification code acquisition request information. The terminal identification may be at least one of a physical address and a telephone number of the terminal.
In step 506, the international mobile subscriber identity corresponding to the extracted terminal identifier is queried in the registration information list.
The registration information list is a list storing international mobile subscriber identities corresponding to the terminal identities.
Specifically, after extracting the terminal identifier from the identifier acquisition request, the gateway reads the registration information list, queries the extracted terminal identifier in the registration information list, and extracts the international mobile subscriber identifier corresponding to the queried terminal identifier.
And step 508, encrypting the international mobile subscriber identity to obtain an identity ciphertext.
Specifically, after extracting the international mobile subscriber identity, the gateway acquires a pre-stored encryption key, and encrypts the international mobile subscriber identity according to the encryption key to obtain an identity ciphertext.
In one embodiment, the gateway extracts the identifier after querying the international mobile subscriber identifier in the registration information list, queries the extracted identifier in the encryption key list, and extracts the encryption key corresponding to the identifier. And the gateway encrypts the international mobile subscriber identity according to the extracted encryption key to obtain an identity ciphertext.
And 510, inserting the identification code ciphertext into the identification code acquisition request to generate a terminal access request.
Specifically, after obtaining the identification code ciphertext, the gateway inserts the identification code ciphertext into the identification code acquisition request, generates a terminal access request, and sends the generated terminal access request to the server. For example, the gateway sends a terminal access request to a server of the operator a through the network.
In one embodiment, the gateway acquires the request information according to the identification code ciphertext and the identification code, generates a terminal access request packet, and sends the terminal access request packet to the server.
In this embodiment, the gateway receives an identifier acquisition request sent by the terminal, extracts a terminal identifier in the identifier acquisition request, queries an international mobile subscriber identifier corresponding to the extracted terminal identifier in a registration information list, encrypts the international mobile subscriber identifier to obtain an identifier ciphertext, inserts the identifier ciphertext into the identifier acquisition request, and generates a terminal access request.

As shown in fig. 6, in an embodiment, after step 206, a step of sending a network handover notification is further included, where the step specifically includes the following steps:
Specifically, when the server does not inquire the network identifier in the access right verification list, the network identifier is not verified by the access right verification list. And the server reads the network identification list, inquires the network identification extracted from the terminal access request in the network identification list, and extracts the operator identification corresponding to the inquired network identification. The network identifier list is a list storing each operator identifier and a network identifier corresponding to each operator identifier.
The network switching notification is notification information for reminding the terminal to switch the operator network.
Specifically, after determining the operator identifier corresponding to the network identifier, the server generates a network switching notification according to the operator identifier, so as to remind a user of the terminal to switch the network of the terminal to the network of the specified operator.
For example, after determining that the operator identifier corresponding to the network identifier is the operator B, the server generates a network switching notification, where the network switching notification is used to remind a user of the terminal to switch the operator network from the operator B to the operator a.
Specifically, after generating the network switching notification, the server sends the network switching notification to the terminal corresponding to the terminal network address, so that the terminal switches the operator network according to the operator identifier in the network switching notification.
