Abstract

Abstract A mobile subscriber is able to request an outgoing call setup without dialing a Numbering Plan Area (NPA) number. A mobile subscriber specifies a particular NPA number to be used with all subsequently dialed local calls. The user specified NPA number is encapsulated into an Unstructured Supplementary Service Data (USSD) message and transported over to the associated home location register (home HLR). Whenever the mobile station performs a location update, or stores a new NPA number, the home HLR copies the stored NPA number to the serving mobile switching center (MSC). Subsequently, whenever the mobile station originates an outgoing call setup with only a local directory number, the MSC retrieves the copied NPA number and generates a complete B-number by concatenating the retrieved NPA number with the subscriber dialed local directory number. The generated B-number is then utilized to properly process the outgoing call setup.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 180 words
A method for generating a B-number within a mobile telecommunications system supporting a plurality of basic calling services, said B-number comprising a first number and a second number, said method comprising the steps of: receiving for each individual one of the plurality of basic calling services a particular first number from a mobile station; storing said particular first number linked to its specified basic calling service in a home location register associated with said mobile station; copying said particular first number to a first register within a mobile switching center whenever said mobile switching center performs a location update procedure with said home location register; receiving a request to originate a call from said mobile station, said request including a dialed second number; identifying which certain one of the plurality of basic calling services is being implicated by the originated call; retrieving said particular first number from said first register that is linked to the identified certain basic calling service implicated by the originated call; and generating said B-number by prepending said retrieved particular first number to said second number.
Claim 2
Independent Claim 180 words
A method for generating a B-number within a mobile telecommunications system supporting a plurality of basic calling services, said B-number comprising a first number and a second number, said method comprising the steps of: receiving for each individual one of the plurality of basic calling services a particular first number from a mobile station; storing said particular first number linked to its specified basic calling service in a home location register associated with said mobile station; copying said particular first number to a first register within a mobile switching center whenever said mobile switching center performs a location update procedure with said home location register; receiving a request to originate a call from said mobile station, said request including a dialed second number; identifying which certain one of the plurality of basic calling services is being implicated by the originated call; retrieving said particular first number from said first register that is linked to the identified certain basic calling service implicated by the originated call; and generating said B-number by prepending said retrieved particular first number to said second number.
Claim 3
Dependent Claim 18 words
The method of claim 1 wherein said particular first number comprises a particular Numbering Plan Area (NPA) number.
Claim 4
Dependent Claim 32 words
The method of claim 2 wherein said mobile station is assigned a NPA number and said particular NPA number is not the same as said NPA number assigned to said mobile station.
Claim 5
Dependent Claim 14 words
The method of claim 2 wherein said second number comprises a local directory number.
Claim 6
Dependent Claim 29 words
The method of claim 1 wherein said step of receiving said particular first number further comprises the step of receiving said particular first number over a connection-less communications link.
Claim 7
Dependent Claim 27 words
The method of claim 5 wherein said step of receiving further comprises the step of receiving said first number using an Unstructured Supplementary Service Data (USSD) message.
Claim 8
Dependent Claim 20 words
The method of claim 1 wherein said plurality of basic calling services comprise voice calls, fax calls and data calls.
Claim 9
Independent Claim 223 words
A system for generating a B-number within a mobile telecommunications system supporting a plurality of basic calling services for a mobile station, said B-number comprising a first number and a second number, said mobile station dialing only said second number, said system comprising: a receiver for receiving a particular first number for each individual one of the plurality of basic calling services, each first number received over a connection-less communications link from said mobile station; a home location register for initially storing said particular first number; a first register within a mobile switching center serving said mobile station for storing said particular first number linked to its specified basic calling service; means for retrieving said particular first number from said home location register for storing in said first register whenever said mobile switching center performs a location update procedure with said home location register; and a processor including means, responsive to a mobile station request to originate an outgoing call with said second number, for identifying which certain one of the plurality of basic calling services is being implicated by the originated call, retrieving said particular first number from said first register that is linked to the identified certain basic calling service implicated by the originated call and for generating said B-number by prepending said retrieved particular first number to said second number.
Claim 10
Independent Claim 223 words
A system for generating a B-number within a mobile telecommunications system supporting a plurality of basic calling services for a mobile station, said B-number comprising a first number and a second number, said mobile station dialing only said second number, said system comprising: a receiver for receiving a particular first number for each individual one of the plurality of basic calling services, each first number received over a connection-less communications link from said mobile station; a home location register for initially storing said particular first number; a first register within a mobile switching center serving said mobile station for storing said particular first number linked to its specified basic calling service; means for retrieving said particular first number from said home location register for storing in said first register whenever said mobile switching center performs a location update procedure with said home location register; and a processor including means, responsive to a mobile station request to originate an outgoing call with said second number, for identifying which certain one of the plurality of basic calling services is being implicated by the originated call, retrieving said particular first number from said first register that is linked to the identified certain basic calling service implicated by the originated call and for generating said B-number by prepending said retrieved particular first number to said second number.
Claim 11
Dependent Claim 17 words
The system of claim 8 wherein said particular first number comprises a Numbering Plan Area (NPA) number.
Claim 12
Dependent Claim 28 words
The system of claim 9 wherein said mobile station is assigned a second NPA number and said NPA number is not the same as said second NPA number.
Claim 13
Dependent Claim 14 words
The system of claim 9 wherein said second number comprises a local directory number.
Claim 14
Dependent Claim 19 words
The system of claim 8, wherein said processor is within said mobile switching center (MSC) serving said mobile station.
Claim 15
Dependent Claim 25 words
The system of claim 8 wherein said connectionless communications link comprises a Unstructured Supplementary Service Data (USSD) system and said receiver comprises a USSD handler.
