Description
Technical field
The present invention relates to communication technical field, particularly a kind of multimodality soft switchcall server and there is the multimodality communication equipment of this multimodality soft switchcall server.
Background technology
Soft switch is the key technology in NGN (Next Generation Network, next generation network) architecture, and its core concept is hardware replace by software, and the calling that realizes original switch by software is controlled, continued and the function such as Business Processing.Each inter-entity is connected with agreement by standard interface and communicates by letter, and the various new business that provides flexibly, is easily and fast provided in next generation network.In legacy circuit-switched networks, call out to control, business provides and switching matrix all concentrates in stored-program control exchange, when a new business is provided, to transform all switches in network, new business provide the cycle long.Soft switch is based on IN(Intelligent Network, intelligent network) in business provide with call proceeding control the separated thought of function realize business provide with call out control separated.In traditional circuit switching exchange, software, hardware and application are synthesized in a switching system, the inner proprietary protocol that uses, technical attendant difficult in maintenance, needs are special, the various functions or the service needed that offer user complete at each switching node, new business generation cost is high, the cycle is long, technology evolution difficulty.And in soft switchcall server, adopt open network architecture system, the functional module of legacy circuit-switched machine is separated into independently network components, as user's plate develops into IAD, relay plate develops into Tandem Gateway, switching matrix develops into Packet Based Network, call out to control develop into soft switch, business provides and is independent of network.All parts can be divided independent development, dilatation and upgrading by corresponding function, interface between each parts based on standard agreement to realize the intercommunication of heterogeneous network, business provides with calling out control and is separated, calls out control and carry the needs that are separated to meet business fast development, the multimedia integration application of support voice, data, video.
Existing soft switching communication system is proposed by fixed network, is not suitable for mobile communications network, and and unrealized business and control strictly separated.Existing soft switching communication system is the same with conventional switch, providing of basic telecommunications business, supplementary service, bearer service etc. has still been provided, just to IN service and the value-added service by parlay interface, provide more flexible, in addition soft switchcall server only core net partly adopt IP (Internet Protocol, the agreement interconnecting between network) framework, can not realize the fusion of network.
