Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of structure and implementation method of mobile Dispatching Exchange System.
Background technology
Build miniaturized core net, realize the major function of each network element of mobile core network, and on this basis, superposition scheduling controlling function, supports dispatching communication business and the mobile communication business of fixed-line subscriber and mobile wireless cellular network terminal user.Mobile Dispatching Exchange System is made up of Dispatching Exchange System, service server, can be connected with mobile wireless honeycomb access network with telephone switching network (as ISDN, PSTN, NGN), for fixing and mobile subscriber provide voice communication and packet multimedia business, and full-duplex voice dispatching communication function can be realized.
Existing Dispatching Exchange System is grown up by fixing program-controlled exchange network at first, by increasing scheduling feature in program-controlled phone switching system, completes the voice scheduling function to fixing wire user.Although this equipment application is very ripe, can not support that user moves, can not realize the multimedia service of packet domain, thus application scenarios is more limited.Along with industry user is to communication and the continuous change of scheduling feature demand and evolution, this fixed schedule systems grow is difficult to the requirement adapting to mobile communication scene.
It is dispatching patcher based on IP and Softswitch technology that existing Dispatching Exchange System also has a kind of, except possessing the function of general PBX system, also can support that dispatched users realizes some special dispatch call processing capacities, support to adopt VOIP technology, complete voice call and scheduling feature.This type of system features is that cost is lower, realizes simple.But major defect cannot provide mobility support to user, although market there is the mobile dispatching patcher supporting WLAN wireless access terminal, but WLAN technology is causing the effect of actual mobile communication to the defect in user mobility support and wireless coverage and bad, and signal penetrability is poor, when user's periphery exists barrier, call is difficult to reach good result.
Above two kinds of dispatching patchers mainly realize the communication scheduling to fixing and wire user.Existing mobile Dispatching Exchange System has a kind of based on PHS technology, is generally made up of central server, scheduling switch, base station controller, base station, phs terminal equipment and Subscriber Identity Module.Scheduling switch is connected with base station controller, and base station controller is connected with base station, and base station is connected to communication antenna and positioning antenna, and base station receives the wireless communication signals of PHS handheld terminal by communication antenna.By PHS scheduling switch, user can complete mobile voice call and short message service by phs terminal equipment, and systems support dispatch platform has accessed the dispatching communication to PHS mobile terminal device or wireline telephone terminal.
Based on the mobile dispatching patcher of PHS technology, advantage is low cost, removable.But its backwardness in technology standard, and face the restriction of country to the clear follow-up maintenance brought after policy causes industrial chain chain rupture frequently of PHS technology and development.Its bandwidth is narrower, and transmission network is generally signalling system No.7 network based on E1/T1 and time gas exchange, business is based on speech business, can not provides effective support to broadband services such as mobile packet multimedias.Because PHS base station radio coverage is little, also less to the scope of the mobility support of user, can not meet user fast and move on a large scale time communication service needs.
Mobile dispatching patcher based on public network also has application at home, mainly based on the digital cluster system of CDMA as GoTa system.This system can realize group calling and group busy intercommunication function, and supports superposition Packet Service.In this overall system or based on the group calling system on public mobile network, be not positioned to realize full-duplex voice dispatching communication, and need the GoTa digital group mobile phone of configure dedicated, need the wireless cellular network of deployment-specific as GoTa base station and GoTa base station controller.
