Abstract

Abstract Interexchange carriers make their rate information for long-distance service available in a database. PBXs and telephone central offices access that rate information using ISDN and/or SS7 signaling and use it as a basis for determining which carder to use at any given time in the routing of a call. Such accessing may be carried out on a call-by-call basis. Or a carrier's schedule of rates can be stored locally in the PBX or local switching office, thereby obviating the need for a database query for every call.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 128 words
A method, for use by a telecommunications carrier, which routes calls over a telecommunications network, said method comprising the steps of storing, in a database, rate information defining the toll rates currently in effect for at least one class of calls routed over said telecommunications network, and providing, to a source of said calls, via a telecommunications signaling path connected to said database, at least a portion of said rate information, said telecommunications signaling path including an SS7 signaling link, said source of said calls being telecommunications switching equipment which receives said calls from originating telephone station equipment and routes said calls to said telecommunications network, and said toll rates being the toll rates that apply to calls made from said telephone station equipment to respective called destinations.
Claim 2
Independent Claim 128 words
A method, for use by a telecommunications carrier, which routes calls over a telecommunications network, said method comprising the steps of storing, in a database, rate information defining the toll rates currently in effect for at least one class of calls routed over said telecommunications network, and providing, to a source of said calls, via a telecommunications signaling path connected to said database, at least a portion of said rate information, said telecommunications signaling path including an SS7 signaling link, said source of said calls being telecommunications switching equipment which receives said calls from originating telephone station equipment and routes said calls to said telecommunications network, and said toll rates being the toll rates that apply to calls made from said telephone station equipment to respective called destinations.
Claim 3
Dependent Claim 15 words
The invention of claim 1 wherein said telecommunications signaling path includes a signal transfer point.
Claim 4
Dependent Claim 12 words
The invention of claim 1 wherein said database is an active database.
Claim 5
Dependent Claim 26 words
The invention of claim 1 wherein said portion of said rate information includes rate information applicable to calls which originate from said source of said calls.
Claim 6
Dependent Claim 37 words
The invention of claim 1 wherein, in said providing step, said portion of said rate information is provided in response to a query requesting rate information applicable to calls which originate from said source of said calls.
Claim 7
Dependent Claim 30 words
The invention of claim 1 comprising the further step of changing at least a portion of said stored rate information as a function of at least a first predetermined criterion.
Claim 8
Independent Claim 116 words
A method for use by a telecommunications carrier which routes calls over a telecommunications network, said method comprising the steps of storing, in a database, rate information defining the toll rates currently in effect for at least one class of calls routed over said telecommunications network, changing at least a portion of said stored rate information as a function of at least a first predetermined criterion, and providing, to a source of said calls, via a telecommunications signaling path connected to said database, at least a portion of said rate information, said telecommunications signaling path including an SS7 signaling link, said portion of said rate information is provided in response to the occurrence of said changing.
Claim 9
Independent Claim 116 words
A method for use by a telecommunications carrier which routes calls over a telecommunications network, said method comprising the steps of storing, in a database, rate information defining the toll rates currently in effect for at least one class of calls routed over said telecommunications network, changing at least a portion of said stored rate information as a function of at least a first predetermined criterion, and providing, to a source of said calls, via a telecommunications signaling path connected to said database, at least a portion of said rate information, said telecommunications signaling path including an SS7 signaling link, said portion of said rate information is provided in response to the occurrence of said changing.
Claim 10
Dependent Claim 26 words
The invention of claim 6 wherein said first predetermined criterion is a function of the operational status of at least one element of said telecommunications network.
