Abstract: A hardware configuration, a general packet radio services support node (GSN) and method for implementing general packet radio services over a global system for mobile communications network is provided. The hardware configuration comprises a plurality of electronic boards which provide the GPRS functionality. An internal bus, preferably CPCI, provides intra-configuration communications while a ATM bus provides communications to an external circuit. The GSN comprises a single board computer for providing general packet radio services functionality which is required for each call being serviced and a line card processor for providing general packet radio services functionality which is required for each packet being serviced. The GSN may function as a SGSN, GGSN or both.

Abstract: A telecommunication network including one or more personal communication networks with a conference bridge for making voice conference connections between some of a plurality of mobile telephones associated with a personal communication network having a plurality of mobile subnetworks respectively for providing mobile telephone service to the plurality of mobile telephones as well as with fixed-location or non-mobile telephones associated with a Public Switched Telephone Network switching center provided with a disconnection voice conferencing system that detects disconnection of a communication link between any one of the mobile telephones and the communications bridge, distinguishes between an intentional disconnection and accidental disconnection of the one mobile telephone, and if the disconnection is determined to have been unintentional, automatically establishes reconnection of the communication link.

Abstract: A method for scaling-up an existing and successfully operating telecommunication system to an increased capability telecommunication system by using newer, higher performance components while keeping as much of the original software and hardware architecture as possible. To provide this scaling capability a detailed modeling method is disclosed which allows individual attention to each process of the original software to determine the impact of scaling on key performance parameters such as cycle time. With this method re-use levels of 80-90% of the existing software have been achieved when moving to increased capability telecommunication systems. This re-use means scaled-up systems will have lower development costs and lower risk of software error since a great majority of the software has already been tested and corrected. The model also allows big problems to be discovered and solved in the laboratory instead of at a field installation site where costs will be higher and development more complicated.
