EXTENDING SIP FOR UPLOADING SUBSCRIBER'S SERVICE PROFILE FROM HSS TO CSCF

摘要

The invention proposes a method for transmitting subscriber information from a first network element to a second network element, comprising the steps of inserting subscriber information in a specific message (1) of the same call control protocol that is used to establish the call; and sending the message from the first network element to the second network element. By this method, subscriber information can be easily uploaded from the first network element (e.g., a HSS) to the second network element (e.g., a CSCF). The invention also proposes a corresponding network system.
