Abstract

Embodiments of this application provide an identity information processing method, a database control system, a service capability exposure function, and a home subscriber server, so as to dynamically establish a correspondence between external identity information and intra-network identity information, thereby simplifying an operation process of establishing the correspondence. In this way, the correspondence between the external identity information and the intra-network identity information is dynamically established, so as to reduce correspondence establishment complexity.

Claims

1. An identity information processing method, comprising:

receiving, by a database control system, registration information sent by a third-party application server, wherein the registration information comprises an Internet Protocol (IP) address of user equipment (UE) and external identity information of the UE, and wherein the external identity information is allocated by the third-party application server to the UE;

sending, by the database control system, the IP address to a target network element, wherein the target network element comprises a Mobile Edge Computing (MEC), wherein the IP address is a public IP address, and wherein the intra-network identity information comprises a private IP address;

receiving, by the database control system, intra-network identity information of the UE that is returned by the target network element based on the IP address; and

establishing, by the database control system, a correspondence between the external identity information and the intra-network identity information.

2. The method according to claim 1, wherein the target network element comprises a packet data network gateway (PGW), and wherein the intra-network identity information comprises an international mobile subscriber identity (IMSI) or a mobile subscriber international ISDN number MSISDN.

3. The method according to claim 2, wherein

when the IP address is a public IP address, the method further comprises:

receiving, by the PGW, the public IP address sent by the database control system;

obtaining, by the PGW, a private IP address based on the public IP address;

obtaining, by the PGW, the IMSI or MSISDN based on the private IP address; and

sending, by the PGW, the IMSI or MSISDN to the database control system;

or

when the IP address is a private IP address, the method further comprises;

receiving, by the PGW, the private IP address sent by the database control system;

obtaining, by the PGW, the IMSI or MSISDN based on the private IP address; and

sending, by the PGW, the IMSI or MSISDN to the database control system.

4. The method according to claim 1, wherein the method further comprises:

receiving, by the database control system, a deletion request sent by the third-party application server, wherein the deletion request is sent by the third-party application server when a terminal corresponding to the private IP address exits the third-party application server; and

deleting, by the database control system, the correspondence between the external identity information and the intra-network identity information according to the deletion request.

5. The method according to claim 1, wherein after the establishing, by the database control system, a correspondence between the external identity information and the intra-network identity information, the method further comprises:

receiving, by the database control system, external identity information sent by a preset network element;

determining, by the database control system based on the correspondence between the external identity information and the intra-network identity information, intra-network identity information that corresponds to the external identity information sent by the preset network element; and

sending, by the database control system, the determined intra-network identity information to the preset network element.

6. The method according to claim 5, wherein the preset network element comprises a home subscriber server (HSS), a service capability exposure function (SCEF), or a Mobile Edge Computing (MEC).

7. A database control system, comprising:

a receiver, the receiver configured to receive registration information sent by a third-party application server, wherein the registration information comprises an Internet Protocol (IP) address of a user equipment (UE) and external identity information of the UE, and wherein the external identity information is allocated by the third-party application server to the UE;

a transmitter, the transmitter configured to send the IP address to a target network element, wherein the target network element comprises a Mobile Edging Computing (MEC), wherein the IP address is a public IP address, wherein the intra-network identity information comprises a private IP address, and wherein

the receiver is further configured to receive intra-network identity information of the UE that is returned by the target network element based on the IP address; and

at least one processor, the at least one processor configured to establish a correspondence between the external identity information and the intra-network identity information.

8. The database control system according to claim 7, wherein the target network element comprises a packet data network gateway (PGW), and wherein the intra-network identity information comprises an international mobile subscriber identity (IMSI) or a mobile subscriber international ISDN number (MSISDN).

9. The database control system according to claim 7, wherein

the receiver is configured to receive a deletion request sent by the third-party application server, wherein the deletion request is sent by the third-party application server when a terminal corresponding to the private IP address exits the third-party application server;

and

the at least one processor is configured to delete the correspondence between the external identity information and the intra-network identity information according to the deletion request.

10. The database control system according to claim 7, wherein

the receiver is further configured to receive external identity information sent by a preset network element;

the at least one processor is further configured to determine, based on the correspondence between the external identity information and the intra-network identity information, intra-network identity information that corresponds to the external identity information sent by the preset network element; and

the transmitter is further configured to send the determined intra-network identity information to the preset network element.

11. The database control system according to claim 10, wherein the preset network element comprises a home subscriber server (HSS), a service capability exposure function (SCEF), or a Mobile Edge Computing (MEC).

12. A communications system, wherein the communications system comprises a database control system, a target network element, and a third-party application server;

and

wherein the database control system is configured to;

receive registration information sent by a third-party application server, wherein the registration information comprises an Internet Protocol (IP) address of user equipment (UE) and external identity information of the UE, and wherein the external identity information is allocated by the third-party application server to the UE;

send the IP address to a target network element, wherein the target network element comprises a Mobile Edge Computing (MEC), wherein the IP address is a public IP address, and wherein the intra-network identity information comprises a private IP address;

receive intra-network identity information of the UE that is returned by the target network element based on the IP address; and

establish a correspondence between the external identity information and the intra-network identity information.
