TELECOMMUNICATION CALLING PARTY NUMBER DETERMINATION AND MANIPULATION

摘要

An apparatus, method and system are illustrated which provide for calling party number determination and manipulation, utilizing digit analysis. One of the switch embodiments includes a network interface, a memory, and a processor. The network interface receives an incoming message having a received calling party numbe r and transmits an outgoing message. The memory stores, as a database module, a plurality of digit trees for digit analysis and a plurality of available manipulations. T he processor includes instructions to perform digit analysis of the received calling part y number to determine a pattern match and to determine a selected manipulation of the plurality of available manipulations, and to perform the selected manipulation on the received calling party number to form a modified calling party number. The processor includes further instructions, when a pattern match has been determined, to direct the networ k interface to transmit the modified calling party number in the outgoing message, and when a pattern match has not been determined, to direct the network interface to transmit the received calling party number in the outgoing message. The database module m ay be modified for calling party number format variability, such as for international use.
