Mobile communication system and a method for connecting a remote workstation to a data communication network via a mobile communication network
First Claim
1. A mobile communication system, comprising:
- a mobile data unit acting via a digital mobile communication network as a remote workstation in a data network;
a mobile exchange;
means for establishing a digital data connection between said mobile data unit and said mobile exchange; and
an interconnecting computer attached to said mobile exchange, the interconnecting computer being connected to said data network by a digital interface and arranged for extending said digital data connection and simulating said remote workstation towards said data network in order to establish a digital end-to-end connection between said mobile data unit and any other party in said data network.

Abstract
A mobile communication system and a method for connecting a remote workstation to a data network via a mobile communication network, which allow a remote workstation to be connected more flexibly over a radio path by providing a special interconnecting computer in conjunction with a mobile exchange for extending the connection to a designation data network. The interconnecting computer thus acts as a bus between the remote workstation using the mobile communication network and its home data network, simulates the operation of the remote workstation towards the data network, and takes care of the real remote workstation, which is behind the radio path. A data connection established over the radio path can be released so as to minimize the air time when the radio path is not needed for telecommunication, but the interconnecting computer keeps the extended connection active towards the data network.

8. A method for connecting a remote workstation to a data network via a digital mobile communication network, comprising the steps of:
-
starting a data session from said remote workstation; establishing a digital data connection over a radio path between said remote workstation and an interconnecting computer connected to said data network by a digital interface in said mobile communication network for said data session; extending said digital data connection between said mobile communication network and said data network by said interconnecting computer in order to establish a digital end-to-end connection between said mobile data unit and any other party in said data network; and temporarily releasing said digital data connection in said mobile communication network during said data session, and, when said digital data connection has been temporarily released; a) maintaining said digital data connection extended towards said data network by said interconnected computer; b) simulating operation of said remote workstation towards said data network at said interconnected computer; and c) monitoring communication addressed from said data network to said remote workstation at said interconnected computer, and upon sensing existence of a communication addressed from said data network to said remote workstation transmitting a notification to said remote workstation over said radio path by sending a connectionless message transmission. - View Dependent Claims (9, 10, 11, 12, 13)
