Dual stack mobile communication system
First Claim
1. A dual stack mobile communication system of a mobile communication network in which an old synchronous network and a new asynchronous network coexist, which forms a single node by combining same kind nodes of the old network and the new network, wherein the single node searches information for generating two output signal points according to a synchronous protocol and an asynchronous protocol in one input signal point according to the synchronous protocol or asynchronous protocol, and generates one output signal point.

Abstract
The present invention discloses a dual stack mobile communication system for building a single interworking network of an old network which is a 2G/2.5G synchronous mobile communication network such as CDMA2000 communication network and a new network which is a 3G asynchronous mobile communication network such as a universal mobile telecommunications service (UMTS) network in a mobile communication network where the old network and the new network have coexisted the dual stack mobile communication system of the mobile communication network in which the old synchronous network and the new asynchronous network coexist forms a single node by combining same kind nodes of the old network and the new network, wherein the single node searches information for generating two output signal points according to a synchronous protocol and an asynchronous protocol in one input signal point according to the synchronous protocol or asynchronous protocol, and generates one output signal point. As a result, the dual stack mobile communication system can smoothly interwork the old network and the new network in all the services which have been individually provided in the old network and the new network by overcoming mismatching of messages and subscriber profiles due to different protocols of the two networks, without introducing a gateway and a complicated message flow.
