ABSTRACT:
A method for implementing call-gapping controls in a telecommunications system supporting ported directory numbers comprises receiving control messages at switches and other network elements, which messages include information relating to the type of controls and parameter information for one or more options permitting present or downstream local number portability (LNP) queries. Based on such received control information, a switch or other network entity seeks to process the call toward completion using dialed number and/or corresponding LNP information, or cancel the call in the interest of overall network efficiency. Use of traffic information allows system operators and network databases to impose policies and practices such as use of dialed number for routing notwithstanding the availability of location routing number information.
