Identity Information Processing Method, Database Control System, and Related Device

An identity information processing method, comprising:

• receiving, by a service capability exposure function (SCEF), a first monitoring request sent by a third-party application server, wherein the first monitoring request comprises external identity information and monitoring type information;
• sending, by the SCEF, the external identity information to a database control system;
• receiving, by the SCEF, intra-network identity information sent by the database control system, wherein the intra-network identity information is obtained by the database control system from a pre-established correspondence between the external identity information and the intra-network identity information based on the external identity information sent by the SCEF;
• and
• sending, by the SCEF, a second monitoring request to a home subscriber server (HSS), wherein the second monitoring request comprises the intra-network identity information and the monitoring type information.

An identity information processing method, comprising:

• receiving, by a home subscriber server (HSS), external identity information and monitoring type information that are sent by a service capability exposure function (SCEF);
• sending, by the HSS, the external identity information to a database control system;
• receiving, by the HSS, intra-network identity information sent by the database control system, wherein the intra-network identity information is obtained by the database control system from a pre-established correspondence between the external identity information and the intra-network identity information based on the external identity information sent by the HSS;
• determining, by the HSS, a mobility management entity MME based on the intra-network identity information;
• and
• requesting, by the HSS from the MME, monitoring event information corresponding to the monitoring type information.

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 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.

A service capability exposure function (SCEF), comprising:

• a receiver, the receiver configured to receive a first monitoring request sent by a third-party application server, wherein the first monitoring request comprises external identity information and monitoring type information;
• and
• a transmitter, the transmitter configured to send the external identity information to a database control system, wherein
• the receiver is further configured to receive intra-network identity information sent by the database control system, wherein the intra-network identity information is obtained by the database control system from a pre-established correspondence between the external identity information and the intra-network identity information based on the external identity information sent by the SCEF;
• and
• the transmitter is further configured to send a second monitoring request to an HSS, wherein the second monitoring request comprises the intra-network identity information and the monitoring type information.

A home subscriber server (HSS), comprising:

• a receiver, the receiver configured to receive external identity information and monitoring type information that are sent by an SCEF;
• a transmitter, the transmitter configured to send the external identity information to a database control system, wherein
• the receiver is further configured to receive intra-network identity information sent by the database control system, wherein the intra-network identity information is obtained by the database control system from a pre-established correspondence between the external identity information and the intra-network identity information based on the external identity information sent by the HSS;
• and
• at least one processor, the at least one processor configured to determine a mobility management entity (MME) based on the intra-network identity information, wherein
• the transmitter is configured to request, from the MME, monitoring event information corresponding to the monitoring type information.

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;
• 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.
