MNEMONIC AND SYNONYMIC ADDRESSING IN A TELECOMMUNICATIONS SYSTEM

摘要

Symbol sequences of varying lengths and having logical meanings otherthan as network addresses (e.g., subscriber names), are assigned and used as actualtelecommunications network addresses, without imposition of predefined fixedlengths, formats, or orderings on their constituent segments (e.g., given name,surname), in a call-processing arrangement that uses stored definitions of syntax andgrammar of the network numbering plan. The syntax definitions include definitionsof individual address segments, called symbol strings, which have logical meanings.Each string's definition includes a string length range, a string type, and an indicatorof the string's influence on call treatment (e.g., route) selection. The grammardefinitions include a matrix that defines permissible sequences of string types,including string types which cannot be dialed by users but only result from receipt ofpermissible sequences of strings of user-dialable types, and a matrix that defineswhich string types' influences on call treatment selection may be combined to selecta treatment for a call. A network digit analysis function parses a received call-control symbol sequence by using the stored syntax and grammar definitions toselect a treatment for the call.
