Dialed number recognition arrangement
First Claim
1. A switching system for use in a telecommunications network having a network numbering plan, comprising:
- means, dedicated for use by this switching system exclusive of other switching systems, for storing information defining the network numbering plan;
means for receiving, from a caller served directly by the switching system without intermediacy of other switching systems, any called number not served by this switching system;
means connected to the receiving means and to the storing means for recognizing entire said received number by using the information stored in the storing means; and
means connected to the recognizing means for establishing a connection for the call to a part of the network outside of this switching system only following recognition by the recognizing means of the entire received number.

Abstract
Recognition, including validation, of any dialed number may be fully accomplished entirely at an originating switching system (10) which includes a call-processing arrangement (200) that has stored definitions of the syntax (320, 350) and the grammar (400, 410) of one or more network numbering plans. The syntax definitions include definitions (312) of all individual symbol strings that are valid for the defined network numbering plans. The dialed number is parsed (340) to recognize therein all included symbol strings. Network facilities (16) for the call outside of the originating switching system are seized and used (344) only after all the included symbol strings are recognized and the entire dialed number is validated.

9. A switching system for use in a telecommunications network that is interconnected with at least one other telecommunications network, each one of the networks having its own network numbering plan, comprising:
-
a plurality of means dedicated for use by this switching system exclusive of other switching systems, each for storing information defining the network numbering plan of a different one of the networks; means for receiving, from a caller served directly by the switching system without intermediacy of other switching systems, any called number not served by this switching system and included in the network numbering plan of any one of the networks; means connected to the connecting means and to the plurality of storing means for recognizing entire said received number by using the information stored in the plurality of storing means; and means connected to the recognizing means for establishing a connection for the call from this switching system to another part of any one of the networks only following recognition by the recognizing means of the entire received number. - View Dependent Claims (10, 11, 12)

13. A switching system for use in a telecommunications network having a network numbering plan and wherein callers supply sequences of symbols to specify treatment that is to be given to calls, each sequence comprising at least one symbol string that is defined for the numbering plan of the network, comprising:
-
means, dedicated for use by this switching system exclusive of other switching systems, for storing definitions of the symbol strings of the network numbering plan; means for receiving, from a caller served directly by the switching system without intermediacy of other switching systems, any sequence of symbols specifying a call treatment not provided by the switching system; means connected to the connecting means and to the storing means for recognizing every symbol string of the obtained symbol sequence by using the information stored in the storing means; and means connected to the recognizing means for seizing a facility for the call outside of this switching system only following recognition by the recognizing means of every symbol string of the obtained symbol sequence. - View Dependent Claims (14)

15. A switching system for use in a network of a plurality of interconnected switching systems, comprising:
-
data storage means for storing contents defining a syntax and a grammar of a numbering plan of the network that comprises a plurality of defined symbol strings, the contents that define the syntax comprising definitions of individual ones of the symbol strings of the network numbering plan, said data storage means dedicated for use by said switching system exclusive of other switching systems; means connected to the data storage means and responsive to receipt, from a caller served directly by said switching system without intermediacy of other switching systems, of a sequence of symbols associated with a call and including at least one symbol string of the network numbering plan, for parsing the received sequence by using the syntax-and grammar-defining contents of the data storage means, to recognize in the sequence every included symbol string of the network numbering plan and to determine a meaning within the network numbering plan of each said recognized symbol string; means connected to the data storage means and to the parsing means and responsive to the determined meaning of the at least one recognized symbol string for specifying a treatment to be given to the call, by using the determined meaning of the at least one recognized symbol string and the contents of the data storage means; and means cooperative with the specifying means for giving the specified treatment to the call, the giving means including means for seizing any facility required for the call outside of the switching system only following recognition in the sequence of said every included symbol string.

16. A call-processing method in a telecommunications network having a network numbering plan, comprising the steps of:
-
receiving, from a caller served directly by a switching system without intermediacy of other switching systems, at the switching system any called number not served by the switching system; recognizing entire said received number at the switching system by using stored information dedicated for use by the switching system exclusive of other switching systems and defining the network numbering plan; and establishing a connection for the call to a part of the network outside of the switching system only following recognition of the entire received number. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A call-processing method in a telecommunications network that is interconnected with at least one other telecommunications network, each one of the networks having its own network numbering plan, comprising the steps of:
-
receiving at a switching system of one of the networks, from a caller served directly by the switching system without intermediacy of other switching systems, any called number not served by the switching system and included in the network numbering plan of any one of the networks; recognizing entire said received number at the switching system by using stored information dedicated for use by the switching system exclusive of other switching systems and defining the network numbering plan of each one of the networks; and establishing a call connection for the call from the switching system to another part of any one of the networks only following the recognizing of the entire received number. - View Dependent Claims (25, 26, 27)
