The Intelligent Network (IN) is the standard network architecture specified in the (ITU-T Q.1200 series recommendations ). It is intended for fixed as well as mobile telecom networks. It allows operators to differentiate themselves by providing value-added services in addition to the standard telecom services such as PSTN, ISDN and GSM services on mobile phones. The intelligence is provided by network nodes on the service layer, distinct from the switching layer of the core network, as opposed to solutions based on intelligence in the core switches or telephone equipment. The IN nodes are typically owned by telecommunications operators (telecommunications service providers). IN is supported by the Signaling System #7 (SS7) protocol between telephone network switching centers and other network nodes owned by network operators. ==Examples of IN services== * Televoting * Call screening * Telephone number portability * Toll free calls/Freephone * Prepaid calling * Account card calling * Virtual private networks (such as family group calling) * Centrex service (Virtual PBX) * Private-number plans (with numbers remaining unpublished in directories) * Universal Personal Telecommunications service (a universal personal telephone number) * Mass-calling service * Prefix free dialing from cellphones abroad * Seamless MMS message access from abroad. * Reverse charging * Home Area Discount * Premium Rate calls * Call distribution based on various criteria associated with the call * * Location Based Routing * * Time-based routing * * Proportional call distribution (such as between two or more call centres or offices). * Call queueing * Call transfer 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Intelligent Network」の詳細全文を読む スポンサード リンク
