METHOD AND SYSTEM FOR ESTABLISHING A CONNECTION BETWEEN NETWORK ELEMENTS |
摘要 |
The invention provides a method and system for establishing or handling a connection between a first and a second network element connected to different networks such as GPRS/UMTS and IP-based networks. The connection is established by means of at least one third network element such as a SGSN or GGSN arranged in one of the networks. The third network element is adapted to send, when receiving information on an establishment of a connection, a request to a fourth network element which may be a Call State Control Function (CSCF), a Policy Control Function (PCF), or a Call Processing Server (CPS). The request requests permission for establishing a requested type of connection, or requests a check of a connection parameter, and specifies the first and/or second network element and/or the connection or connection type to be established. The fourth network element returns a response specifying a permission for establishing a connection or connection type, or specifying a connection parameter.(Fig. 1)
