Abstract
Abstract Emergency call handling may, in the near future, require terminal unit location information to be provided to emergency service centers. Exemplary embodiments of the present invention provide techniques which pass the mobile unit's phone number along to an appropriate emergency service centers in addition to location information. This information can be made available to an adjunct monitoring system by either changing the mobile station identity used to package (Layer 2 ) an access attempt or by commanding a mobile or base station to explicitly transmit the mobile unit's dialable number during an emergency access so that the adjunct system can read and forward this number.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
75 words
A method for handling an emergency call in a radiocommunication system, comprising the steps of: identifying, in a mobile unit, a call as one of an emergency call and a non-emergency call; selecting a first mobile unit identifier if said call is an emergency call; selecting a second mobile unit identifier if said call is a non-emergency call; and transmitting a message from said mobile unit to said system using said selected mobile unit identifier.
Claim 2
Independent Claim
75 words
A method for handling an emergency call in a radiocommunication system, comprising the steps of: identifying, in a mobile unit, a call as one of an emergency call and a non-emergency call; selecting a first mobile unit identifier if said call is an emergency call; selecting a second mobile unit identifier if said call is a non-emergency call; and transmitting a message from said mobile unit to said system using said selected mobile unit identifier.
Claim 3
Dependent Claim
18 words
The method of claim 1 , wherein said first mobile unit identifier is a mobile identification number (MIN).
Claim 4
Dependent Claim
19 words
The method of claim 1 , wherein said first mobile unit identifier is an activating mobile identification number (AMIN).
Claim 5
Dependent Claim
19 words
The method of claim 1 , wherein said second mobile unit identifier is a temporary mobile station identifier (TMSI).
Claim 6
Dependent Claim
21 words
The method of claim 1 , wherein said first mobile unit identifier includes a dialable number associated with a mobile unit.
Claim 7
Dependent Claim
58 words
The method of claim 1 further comprising the steps of: receiving, at an adjunct system, said selected mobile unit identifier in signaling data associated with an emergency call from said mobile unit; determining a position of said mobile unit; and forwarding said position and said selected mobile unit identifier from said adjunct system to an emergency service center.
Claim 8
Dependent Claim
29 words
The method of claim 6 , further comprising the step of forwarding to said emergency service center, without routing through the radio communication system, said selected mobile unit identifier.
Claim 9
Independent Claim
78 words
A method for handling an emergency call in a radiocommunication system, comprising the steps of: identifying, in a mobile unit, a call as one of an emergency call and a non-emergency call; retrieving a stored dialable number associated with said mobile unit if said call is an emergency call; retrieving a temporary mobile station identifier (TMSI) if said call is a non-emergency call; and selectively transmitting a message to said system including said dialable number or said TMSI.
Claim 10
Independent Claim
78 words
A method for handling an emergency call in a radiocommunication system, comprising the steps of: identifying, in a mobile unit, a call as one of an emergency call and a non-emergency call; retrieving a stored dialable number associated with said mobile unit if said call is an emergency call; retrieving a temporary mobile station identifier (TMSI) if said call is a non-emergency call; and selectively transmitting a message to said system including said dialable number or said TMSI.
Claim 11
Dependent Claim
31 words
The method of claim 8 , further comprising the steps of: inputting, by a user of said mobile unit, said dialable number to said mobile unit; and storing said dialable number.
Claim 12
Dependent Claim
28 words
The method of claim 8 , further comprising the steps of: transmitting, over an air interface, said dialable number to said mobile unit; and storing said dialable number.
Claim 13
Dependent Claim
66 words
A remote station comprising: means for identifying a call as one of an emergency call and a non-emergency call; means for selecting a first mobile unit identifier if said call is an emergency call; and means for selecting a second mobile unit identifier if said call is a non-emergency call; and means for transmitting a message from said mobile unit using said selected mobile unit identifier.
Claim 14
Dependent Claim
66 words
A remote station comprising: means for identifying a call as one of an emergency call and a non-emergency call; means for selecting a first mobile unit identifier if said call is an emergency call; and means for selecting a second mobile unit identifier if said call is a non-emergency call; and means for transmitting a message from said mobile unit using said selected mobile unit identifier.
