Call routing in a telecommunication system
First Claim
1. A method of routing calls in a telecommunication system comprising a mobile communication system comprising at least one mobile services switching centre and at least one base station connected thereto, and mobile stations wherefrom a telecommunication connection is established to the mobile services switching centre through the base station by using a first predetermined telecommunication protocol on a radio connection, a packet data network wherein data to be transmitted is transmitted in data packets, according to a protocol specified for the packet data network, a server communicating with the mobile services switching centre and said packet data network, the server being configured to arrange messages according to the first telecommunication protocol arranged as such into data packets according to said packet data network protocol and supplied from the mobile communication system to be forwarded through said packet data network to the terminal, the server being further configured to decompress messages according to the first telecommunication protocol arranged as such in the data packets according to said packet data network protocol and supplied from the terminal through the packet data network to be forwarded to the mobile communication system, and at least one terminal, which is arranged to support said packet data network protocol and from which terminal a telecommunication connection is established through the packet data network and the server to the mobile switching centre, the method comprising establishing a telecommunication connection from said terminal to said packet data network by using a second predetermined telecommunication protocol, through which telecommunication connection the data packets according to said protocol specified for the packet data network can be transmitted, transmitting and receiving by said terminal the messages according to the first telecommunication protocol arranged as such into the data packets according to said packet data network protocol, and emulating a mobile station using said first telecommunication protocol by the terminal.

Abstract
A method of routing calls in a telecommunication system comprising a mobile services switching center (MSC) and a base station connected thereto, and mobile stations wherefrom a telecommunication connection is established by using a first predetermined protocol on a radio connection. The telecommunication system further comprises a packet data network, a server communicating with the MSC and the packet data network, wherefrom a telecommunication connection is established through the packet data network and the server to the MSC. In the server, messages according to the first protocol supplied from the MSC are as such arranged into data packets of data network protocol to be forwarded through the packet data network to the terminal. The terminal transmits and receives the messages according to the first protocol arranged as such into the data packets of the packet data network protocol and emulates a mobile station using the first protocol.
