20130137418 | Virtual Trunking System - The present invention discloses a virtual trunking system developed on a value-added platform. At present, information islands are formed among different modes of trunkings, so that interconnection and intercommunication cannot be realized and interconnection and intercommunication of various trunkings with common communication network cannot be realized either. In the technical scheme adopted by the present invention, the virtual trunking system is characterized by comprising a mobile phone software module, a trunking dispatching desk, a terminal access server, a database server, an application server, a virtual trunking business module, a platform support module and a value-added platform, wherein the value-added platform is a CPCI (Compact Peripheral Component Interconnect) value-added platform which provides PCI (Peripheral Component Interconnect) slots and bus exchange; and the value-added platform accesses a public network through a digital relay or an IP (Internet Protocol). In the present invention, the value-added platform is interconnected with a public communication network and the mobile phone terminal serving as a client of the value-added platform is combined with the value-added platform, so that wireless trunking communication is realized. | 05-30-2013 |
