Method for improving service level selection in a communication network system

摘要

The present invention relates to a method for improving service level selection in a communication network system, in which an interworking function (IWF) is arranged between a user terminal (MS) and the network(s) in question, and wherein High Speed Circuit Data (HSCD) are specified, and for the purpose of making this selection in a more expedient manner and allow the user to allocate bandwidth in a more flexible and dynamic way, it is according to the present invention suggested that the interworking function (IWF) is used for signalling to the user terminal (MS) when a change in level selection may be useful.
