| 1. A dual stack mobile communication system of a mobile communication network, comprising:
a synchronous network mobile; and
an asynchronous network mobile,
wherein a single node is formed by combining same kind nodes of the synchronous mobile network and the asynchronous mobile
network,
wherein the single node searches information for generating two output signal points according to a synchronous protocol associated
with the synchronous mobile network and an asynchronous protocol associated with the asynchronous mobile network using one
input signal point according to the synchronous protocol or asynchronous protocol, and generates one output signal point;
and
wherein the same kind nodes comprise a home location register, a short message service center and a service control point
which is an intelligence network managing device.
