Abstract
Abstract This invention relates to arrangements for controlling processing of telephone calls from feature processors. Feature processors (30) are data bases, usually shared among a plurality of switching systems (10,11) and usually comprising data for customers served by these switching systems, for altering the processing of telephone calls from and to these customers in accordance with that data. In order to perform this modification, data messages are exchanged between the switching systems and the feature processor. In a departure from the prior art, these data messages include functional indicators (44,54) i.e., indicators of basic characteristics of a call, each of which may be associated with many features and which may influence the execution of other features, wherein the execution of at least some of the features of the two groups can be influenced by the feature processor. Advantageously, the use of functional indicators helps to reduce the amount of data to be transmitted between the switching systems and feature processor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
A method of processing a call, comprising: responsive to receipt of data for said call in a switching system, transmitting a request message to a remote feature processor system, for serving a plurality of switching systems, said request message comprising an event indication for a state of said call and indications of active ones of a plurality of functional indicators for said call; responsive to receipt of said request message, processing said request message, using said event indication and using said indications of active functional indicators, to formulate and transmit a response message comprising an indication of a response command to said switching system; and responsive to receipt of said response message, executing said response command in said switching system.
Claim 2
Independent Claim
120 words
A method of processing a call, comprising: responsive to receipt of data for said call in a switching system, transmitting a request message to a remote feature processor system, for serving a plurality of switching systems, said request message comprising an event indication for a state of said call and indications of active ones of a plurality of functional indicators for said call; responsive to receipt of said request message, processing said request message, using said event indication and using said indications of active functional indicators, to formulate and transmit a response message comprising an indication of a response command to said switching system; and responsive to receipt of said response message, executing said response command in said switching system.
Claim 3
Dependent Claim
59 words
The method of claim 1 wherein said request message further comprises customer identification data for said call; wherein said remote feature processor comprises data for customers identified by said customer identification data; and wherein said remote feature processor further modifies the processing of said request message by using said data stored for customers identified by said customer identification data.
Claim 4
Dependent Claim
41 words
The method of claim 1 or 2 wherein said remote feature processor modifies the processing of said request message in response to said indications of active ones of a plurality of functional indicators for said call received in said request message.
Claim 5
Dependent Claim
37 words
The method of claim 3 wherein said remote feature processor modifies ones of said indications of active functional indicators for said call and transmits data relating to said modifications to said switching system in said response message.
Claim 6
Dependent Claim
36 words
The method of claim 4 wherein responsive to receipt of said data relating to said modifications, subsequent processing of said call is modified by at least one of said remote feature processor and said switching system.
Claim 7
Dependent Claim
70 words
The method of claim 2 wherein said functional indicators include one or more of the following: a do not disturb indicator, a multiway controller indicator, a facsimile call indicator, an emergency service indicator, a priority service indicator, an operator assistance call indicator, a test call indicator, a redirected call indicator, a revers charge indicator, an intra-group call indicator, an inter-LATA call indicator, an international call indicator, or a flash indicator.
Claim 8
Dependent Claim
142 words
Apparatus for processing telephone calls comprising: a switching system; a remote feature processor (RFP) means for serving a plurality of switching systems; and data communication means interconnecting said switching system and said remote feature processor means; said switching system for transmitting a request message over said data communication means to said RFP means, said request message comprising an event indication for a state of a telephone call and indications of active ones of a plurality of functional indicators for said call; said RFP means responsive to said request message for processing said request message, using said event indication and said indications of active functional indicators, to formulate and transmit, over said data communication means, to said switching system a response message comprising an indication of a response command; and said switching system responsive to said response message for executing said response command.
Claim 9
Dependent Claim
142 words
Apparatus for processing telephone calls comprising: a switching system; a remote feature processor (RFP) means for serving a plurality of switching systems; and data communication means interconnecting said switching system and said remote feature processor means; said switching system for transmitting a request message over said data communication means to said RFP means, said request message comprising an event indication for a state of a telephone call and indications of active ones of a plurality of functional indicators for said call; said RFP means responsive to said request message for processing said request message, using said event indication and said indications of active functional indicators, to formulate and transmit, over said data communication means, to said switching system a response message comprising an indication of a response command; and said switching system responsive to said response message for executing said response command.
Claim 10
Dependent Claim
56 words
The apparatus of claim 7 wherein said request message further comprises customer identification data for said call; wherein said RFP means comprises data for customers identified by said customer identification data; and wherein said RFP means further modifies processing of said request message by using said data stored for customers identified by said customer identification data.
Claim 11
Dependent Claim
40 words
The apparatus of claim 7 or 8 wherein said RFP means modifies the processing of said request message in response to said indications of active ones of a plurality of functional indicators for said call received in said request message.
Claim 12
Dependent Claim
36 words
The apparatus of claim 9 wherein said RFP means modifies ones of said indications of active functional indicators for said call and transmits data relating to said modifications to said switching system in said response message.
Claim 13
Dependent Claim
35 words
The apparatus of claim 10 wherein, responsive to receipt of said data relating to said modifications, subsequent processing of said call is modified by at least one of said RFP means and said switching system.
