Abstract
Official abstract text for this publication.
A hierarchical protocol classification and signaling method specifies the interworking protocols used to send circuit-switched signaling messages to and from a mobile terminal in a packet-switched network. A set of possible interworking protocols are divided into two more classes that correspond to different types of interworking protocols. Within each class, different versions of the interworking protocol are specified by a revision value. The versions of the interworking protocols within a given class are may be denominated such that the versions with a higher revision value are backward compatible with versions having a lower value. When a circuit services domain message is sent from a sending device to a receiving device, an interworking option specifying the class/revision of the interworking protocol is transmitted along with circuit services domain messages. The interworking option may be inserted into the header of a tunneling packet containing the circuit services domain message.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of interworking between a packet-switched network and a circuit-switched network, said method comprising: generating a tunneling packet encapsulating a circuit services domain message; sending said tunneling packet with said circuit services domain message from a sending device in one of the circuit-switched or packet-switched networks to a receiving device in the other one of the circuit-switched and packet switched networks; and including an i…
