Title: System and method of delivering roamer port calls in multiple radio telecommunication switches
Inventor: FOTI GEORGE
IPC: H04W68/00
Filed: 1997-05-16
Granted: 2005-07-19
Abstract: A system and method are disclosed for extending roamer port coverage from a single mobile switching center (MSC) to a plurality of associated MSCs within a visited radio telecommunications network (70) in which a mobile subscriber (19) is roaming. In a first MSC (73), a roamer port number is defined to cover the associated plurality of MSCs (74, 75) within the visited radio telecommunications network (70).      When a call is received through the roamer port number for the roaming mobile subscriber (19), the first MSC (73) simultaneously places calls by seizing trunks (76) to each of the associated plurality of MSCs (74, 75), and instructs each of the associated plurality of MSCs to simultaneously page for the roaming mobile subscriber (19). Alternatively, the first MSC may utilize network signaling messages to notify each of the associated plurality of MSCs (74, 75) that the call is a roamer port call and to instruct each of the MSCs to page for the roaming mobile subscriber (19). Upon receipt of a successful page response in one of the paging MSCs, the call is routed to the MSC with the successful page response.

Abstract: A data transmission method, a data transmission system, a transmitter and a receiver which can reduce the probability of detecting the rate mistakenly at the receiving side and can eliminate the need for providing buffer for temporarily storing the transmitted data at the transmitting side in variable rate data transmission are provided. At the transmitting side, an error-detecting code of the transmitted data is calculated, frame by frame, the error-detecting code is arranged after the corresponding transmitted data, and frame data is generated in such a way that bit arrangements of the transmitted data and of the error-detecting code are set in a reverse order to each other. At the receiving side, the transmitted data and the error-detecting code are assumed by assuming a final bit position of the frame data, frame by frame, for the received frame, data and the error-detecting code of the assumed transmitted data is calculated. Among the assumed final bit positions of the frame data, a position such where the assumed error--detecting code agrees with an error-detecting code calculated on the basis of the assumed transmitted data is determined to be the final bit position of the frame data.

Abstract: A power-conserving time division multiple access (TDMA) radiotelephone system is disclosed in which a cluster of subscriber stations, remote from a base station, employs a common pool of frequency-agile modems each of which digitally synthesizes, on a time slot-by-time slot basis, the different channel-identifying intermediate needed to support communications between several of the subscriber stations and the base station. Power conservation is facilitated inter alia by controlling the assignment of modems to calls, maintaining unassigned modems in a powered-down state and by controlling the number of calls using the same time slot. Delay in assigning a powered-down modem to a call is eliminated by making available to all modems the highest quality synchronization information obtained by any of the active modems.
