301. and the user equipment sends an access request message to the mobile management network element.

When the ue requests to access the mobile communication network, the access Request message may be an Attach Request (Attach Request) message.

302. The mobile management network element sends a location update request message to the home subscriber server.

Because the subscription information of the user equipment does not exist in the mobile management gateway, the mobile management network element requests the home subscriber server of the user equipment to acquire the subscription information of the user equipment through the location updating request information.

303. And the home subscriber server sends the location updating response information to the mobile management network element, wherein the location updating response information carries the monitoring event configuration information of the user equipment.

When the home subscriber server enables the monitoring event characteristic of the user equipment, the home subscriber server can send the monitoring event configuration information of the user equipment to the mobile management network element through the position updating response information.

It should be noted that the determination of whether to enable the monitoring event feature of the ue by the home subscriber server may be performed by the following two methods:

the first method comprises the following steps: storing the configuration information of the monitoring event of the user equipment in the home subscriber server, and directly judging that the user equipment needs to start the monitoring event characteristic;

the second method comprises the following steps: and if the configuration information of the monitoring event of the user equipment is stored in the home subscriber server and the subscription information of the user equipment indicates that the monitoring event characteristic of the user equipment is activated, judging that the user equipment needs to activate the monitoring event characteristic.

The Session management message may be, for example, a Create PDP Context Request (Create PDP Context Request) message or a Create Session Request (Create Session Request) message, and the mobility management element sends configuration information of the monitoring event of the slave user equipment to the gateway device through the Session management message.

306. And the gateway equipment sends a session management response message to the mobile management network element.

After receiving the session management message sent by the mobility management element, the gateway device stores the configuration information of the monitoring event of the ue carried in the session management message, and executes a corresponding session management operation according to the requirement of the session management message, for example, creating a PDP context or creating an Evolved Packet System (EPS) bearer for the ue.

The Session management Response message may be a Create PDP Context Response (english) message or a Create Session Response (english) message.

307. The home subscriber server sends add monitoring configuration request information to the intermediary device.

Wherein, the added monitoring configuration request information includes the internal identifier and the external identifier of the user equipment and the identifier or the address of the corresponding monitoring server.

It should be noted that, if the home subscriber server determines that the additional monitoring configuration request information has been sent to the intermediate device and the intermediate device has already stored the monitoring configuration information of the user equipment through a newly added identification information (for example, a monitoring configuration enabling identification) in the information about the user equipment stored locally, step 307 is not executed; if it is determined that the intermediate node does not save the addition monitoring configuration request information of the user equipment, step 307 is performed.

308. The intermediary sends an add monitoring configuration response message to the home subscriber server.

The intermediate device stores the internal identifier and the external identifier of the ue and the identifier or address of the corresponding monitoring server included in the addition monitoring configuration request message, and may send an addition monitoring configuration response message to the home subscriber server to confirm that the internal identifier and the external identifier of the ue and the identifier or address of the corresponding monitoring server have been received.

It should be noted that, after receiving the addition monitoring configuration response message sent by the intermediary device, the home subscriber server may indicate, through one identification information in the information about the user equipment stored by the home subscriber server, that the intermediary device has already stored the internal identification, the external identification, and the identification or address of the corresponding monitoring server of the user equipment. Therefore, when the user equipment is attached to the mobile communication network later, the home subscriber server does not send the addition monitoring configuration request message to the intermediate equipment any more, so that the phenomenon that the addition monitoring configuration request message is sent to the intermediate equipment repeatedly is avoided, and the signaling overhead can be reduced.

It should be noted that, if the home subscriber server in this embodiment is an intermediate device, the corresponding relationship between the internal identifier of the user equipment, the external identifier of the user equipment, and the identifier and/or address of the corresponding monitoring server may be set by itself.

When the user equipment is attached to the mobile communication network, the embodiment of the invention sends the configuration information of the monitoring event of the user equipment to the monitoring equipment through the home subscriber server so that the monitoring equipment stores the configuration information of the monitoring event of the user equipment; and sending the internal identifier, the external identifier and the identifier or the address of the corresponding monitoring server of the user equipment to the intermediate equipment through the home subscriber server, so that the intermediate equipment can obtain the corresponding external identifier and the corresponding monitoring server address according to the internal identifier of the user equipment when receiving the monitoring event report of the user equipment and the internal identifier of the user equipment, which are sent by the monitoring equipment, thereby sending the monitoring event report and the external identifier of the user equipment to the corresponding monitoring server, and improving the sending accuracy of the monitoring event report of the user equipment.

401. the application function entity sends an application/service information message to the policy and charging rules entity.

Wherein, the application/service information message carries the monitoring event configuration information of the user equipment.

The Application/Service Information message may be an Application/Service Information message.

The application function entity may be an application server of a wireless communication network operator or an application server of a third party.

The application function entity stores the configuration information of the monitoring event of the user equipment, and when the application function entity enables the monitoring event characteristic of the user equipment, the application function entity can send the monitoring event configuration information of the user equipment to the policy and charging rule entity through the application service information message. It is noted that the application function entity may for example obtain monitoring event configuration information of the user equipment from the home subscriber server HSS, assuming that the application function entity is located outside the mobile communication network. When the application function entity needs to send the application/service information message to the policy and charging rule entity, the monitoring event configuration information of the user equipment can be carried in the application/service information message and sent to the policy and charging rule entity.
