Abstract
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 is disclosed. The connection is established via at least a 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, a Policy Control Function, or a Call Processing Server. The request requests permission for establishing a 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 a connection parameter.
