Hybrid packet-switched and circuit-switched telephony system

A hybrid telephony system with packet switching as well as circuit switching optimizes utilization of transport networks, and is accessible from any conventional telephone set. A call originating from a circuit-switched network is passed through a gateway computer to a backbone packet-switched network, and then through a second gateway computer to a second circuit-switched network where it terminates. The voice of both the originating party and the terminating party is converted to data packets by the near-end gateway computer and then converted back to voice by the far-end gateway computer. In an alternative scenario, the originating party uses a computer on the packet-switched network, which replaces the originating circuit-switched network and the originating computer. Powered by CPUs, DSPs, ASICs disks, telephony interfaces, and packet network interfaces, the gateway computers may have media conversion modules, speech processing modules and routing resolution modules, and are capable of translating telephony call signaling as well as voice between circuit-switched and packet-switched networks. Optionally, the gateway computers may also have analog trunking modules, MF and DTMF digit modules and special services modules, in order to support analog circuit-switched networks and secure telephone calls.

Method for automatically reporting station of public transport vehicle

ActiveCN101493990AAccurate and timely station announcementEasy to schedule and manageRoad vehicles traffic controlBroadcastingData sequences
The invention relates to an automatic stop announcement method of a bus, pertaining to a bus information-releasing method. The method solves the problems of difficult data adjustment and low accuracy of stop announcement under a complicated situation, and comprises the following steps: a bus terminal receives and stores a data sequence of stop announcement in a running route, sent out by a control center through mobile communication. When the bus is in running, the bus terminal first combines current GPS location information with stop location information of auxiliary beacons to periodically find out the nearest stop as a current stop in the running route from the data sequence of the stop announcement. The running modes, namely, the uplink or the downlink, is determined when the bus runs into the current stop. And then the bus terminal adjusts the running mode according to the data sequence, controls the broadcasting and displays the information of the current stop; when the bus leaves the stop, the bus terminal, combining the running mode and in accordance with the data sequence, controls the broadcasting and displays leaving information consisting of the name of the next stop, and sets the next stop in the running route as the current stop.
