Method and system for retrieving user information in evolved packet system

16:

• A method for managing an Evolved Packet System, the Evolved Packet System comprising:
• a core network including a database configured to store User Identifying Information of user devices attached to the Evolved Packet System, and
• at least one external server,
• wherein the method comprises:
• having a user device attached to the Evolved Packet System request IP services to the external server;
• in response to said requesting IP services, having the external server request the User Identifying Information of said user device to the core network;
• in response to said requesting the User Identifying Information, having the core network access the database and retrieve the User Identifying Information of said user device;
• having the core network send the retrieved User Identifying Information to the external server;
• having the external server provide the requested IP services to the user device by exploiting said retrieved User Identifying Information.

19:

• The method of claim 18, wherein:
• said Evolved Packet System further comprises a policy management module;
• said requesting the User Identifying Information to the gateway module comprises having the policy management module send a request to the gateway module in the form of additional data enriching signaling messages over a Gx interface,
• said sending the retrieved User Identifying Information to the external server comprises having the gateway module send a reply to the policy management module in the form of additional data enriching signaling messages over said Gx interface.

20:

• The method of claim 18, wherein
• said Evolved Packet System further comprises an Authentication, Authorization and Accounting server;
• said requesting the User Identifying Information to the gateway module comprises having the Authentication, Authorization and Accounting server send a request to the gateway module in the form of additional data enriching signaling messages over a SGi interface,
• said sending the retrieved User Identifying Information to the external server comprises having the gateway module send a reply to the Authentication, Authorization and Accounting server in the form of additional data enriching signaling messages over said SGi interface.

24:

• The method of claim 16, wherein said core network is based on a selected one among the following architectures:
• 2G;
• 3G;
• 4G/LTE;
• 5G.

25:

• The method of claim 16, wherein said User Identifying Information comprises:
• MSISDN and IMSI, or
• IMEI,
• of said user device.

27:

• A method of providing IP services to a user device attached to an Evolved Packet System, the Evolved Packet System comprising:
• a core network including a database configured to store User Identifying Information of user devices attached to the Evolved Packet System, and
• at least one external server configured to provide IP services,
• wherein the method comprises:
• having the user device attached to the Evolved Packet System request IP services to the external server;
• in response to said requesting IP services, having the external server request the User Identifying Information of said user device to the core network;
• in response to said requesting the User Identifying Information, having the core network access the database and retrieve the User Identifying Information of said user device;
• having the core network send the retrieved User Identifying Information to the external server;
• having the external server provide the requested IP services to the user device by exploiting said retrieved User Identifying Information.

28:

• An Evolved Packet System, comprising:
• a core network including a database configured to store User Identifying Information of user devices attached to the Evolved Packet System, and
• at least one external server,
• wherein:
• the external server is configured to request to the core network the User Identifying Information of a user device attached to the Evolved Packet System that is requesting IP services to the external server;
• the core network is configured to access the database, retrieve the User Identifying Information of said user device, and send the retrieved User Identifying Information to the external server in response to said request;
• the external server is further configured to provide the requested IP services to the user device by exploiting said retrieved User Identifying Information.
