Abstract:
A method for reducing transmission of parameters between a first network element and a second network element in a telecommunication network, comprising in sequence the steps of:(a) transmitting a first signaling message from the first network element to the second network element during initial call processing initiated by a subscriber, the first signaling message containing a first set of parameters required by the second network element; (b) transmitting a second signaling message from the second network element to the first network element indicating to the first network element a second set of parameters required by the second network element in response to the first signaling message, wherein the second set of parameters is selected by indicating to the first network any element parameters not required by the second network element so that the second set of parameters includes all other parameters; (c) transmitting the second set of parameters in a third signaling message from the first network element to the second network element in response to the second signaling message; and (d) during subsequent call processing, transmitting a fourth signaling message containing both the first set of parameter's and the second set of parameters from the first network element to the second network element without requiring the second network element to again indicate to the first network element the second set of parameters required by the second network element in response to the first signaling message.
