Method and terminals for support of functional numbering applied to enhanced messaging services in wireless communication networks

摘要

A method for extension of Functional Numbering applied to standard Short Messaging Services (SMS/EMS = 'Short Messaging Service/Enhanced Messaging Service') in a communication network with wireless mobile terminals that includes network functions for management of Functional Numbering for voice communication is described. In accordance with the method a terminal that is sender of an SMS/EMS message inserts in an Information Element (IE) field of the User Data Header of the SMS/EMS message the Functional Number (FN) of the sender and inserts in the identifier of said IE field an IE_ID value chosen to identify a functional SMS/EMS. A terminal that receives an SMS/EMS seeks in the identifier of the IE fields of the User Data Header of the SMS/EMS message received the value chosen to identify a functional SMS/EMS and if it finds it extracts the content of the corresponding IE field and uses it as the Functional Number FN of the sender of the SMS/EMS message received.
