Abstract
Abstract A mobile station is disclosed which may be operated in both a set-up programming mode and in an authentication key programming mode. The authentication key programming mode may be invoked through a series of keystrokes on a keypad in the mobile station. The mobile station allows the entry of a separate authentication key for each mobile station identification number stored in memory. The mobile station also checks the accuracy of the entered authentication key and alerts the user as to whether the entered authentication key is valid or invalid.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
97 words
A mobile station comprising: a plurality of data entry keys; means for operating said mobile station in a plurality of programming modes including an authentication key programming mode and a number administration module (NAM) programming mode; means for enabling the selection of one of said programming modes through said data entry keys; a memory containing at least one mobile identification number (MIN); means for receiving an authentication key (A-key) entered by the user while said authentication key programming mode is selected; and means for storing the entered A-key with said at least one MIN in said memory.
Claim 2
Dependent Claim
97 words
A mobile station comprising: a plurality of data entry keys; means for operating said mobile station in a plurality of programming modes including an authentication key programming mode and a number administration module (NAM) programming mode; means for enabling the selection of one of said programming modes through said data entry keys; a memory containing at least one mobile identification number (MIN); means for receiving an authentication key (A-key) entered by the user while said authentication key programming mode is selected; and means for storing the entered A-key with said at least one MIN in said memory.
Claim 3
Dependent Claim
20 words
The mobile station of claim 1 wherein said authentication key programming mode is selected through a unique series of keystrokes.
Claim 4
Dependent Claim
61 words
The mobile station of claim 1 wherein said mobile station stores in said memory a plurality of mobile identification numbers (MINs), and wherein: said receiving means comprises means for prompting the user to enter an authentication key (A-key) for each of said MINs; and said storing means comprises means for storing the entered A-key with the corresponding MIN in said memory.
Claim 5
Dependent Claim
25 words
The mobile station of claim 3 further comprising means for validating the entered A-key prior to being stored with the corresponding MIN in said memory.
Claim 6
Dependent Claim
23 words
The mobile station of claim 4 further comprising means for generating an audible or visual indication of whether the entered A-key is valid.
Claim 7
Independent Claim
167 words
A method for entering authentication information into a mobile station which is assigned at least one mobile identification number (MIN), said at least one MIN being stored in said mobile station, comprising the steps of: assigning a separate authentication key (A-key) for each of said at least one MIN stored in said mobile station; displaying in said mobile station an indication of any stored MIN in response to a user-entered command; receiving in said mobile station a value of the A-key entered by the user for storing with the indicated MIN; validating the received value of the A-key through an authentication algorithm executed in said mobile station; storing in said mobile station the received A-key value with the indicated MIN if the received A-key value is determined to be valid; and arranging said mobile station to receive new value of the A-key, to be entered by the user for storing with the indicated MIN or another MIN, if the received A-key value is determined to be invalid.
Claim 8
Independent Claim
167 words
A method for entering authentication information into a mobile station which is assigned at least one mobile identification number (MIN), said at least one MIN being stored in said mobile station, comprising the steps of: assigning a separate authentication key (A-key) for each of said at least one MIN stored in said mobile station; displaying in said mobile station an indication of any stored MIN in response to a user-entered command; receiving in said mobile station a value of the A-key entered by the user for storing with the indicated MIN; validating the received value of the A-key through an authentication algorithm executed in said mobile station; storing in said mobile station the received A-key value with the indicated MIN if the received A-key value is determined to be valid; and arranging said mobile station to receive new value of the A-key, to be entered by the user for storing with the indicated MIN or another MIN, if the received A-key value is determined to be invalid.
Claim 9
Dependent Claim
35 words
The method of claim 6 wherein said mobile station operates in at least two modes, including a set-up programming mode and an A-key programming mode, and wherein said user-entered command invokes said A-key programming mode.
Claim 10
Dependent Claim
30 words
The method of claim 6 further comprising the step of displaying an indication of the validity of the received A-key value as determined from the execution of said authentication algorithm.
Claim 11
Dependent Claim
85 words
The method of claim 6 wherein said mobile station stores the MIN corresponding to the system in which said mobile station is operating, and at least one other MIN corresponding to a different system, and wherein said displaying step comprises the steps of: displaying an indication of the MIN corresponding to the system in which said mobile station is operating; and displaying an indication of another MIN in response to a user-entered command, said indication of another MIN replacing said indication of the operating MIN.
Claim 12
Dependent Claim
15 words
The method of claim 6 wherein said MIN indication comprises the value of the MIN.
Claim 13
Independent Claim
174 words
A system for entering authentication information into a mobile station which is assigned at least one mobile identification number (MIN), said at least one MIN being stored in said mobile station, comprising: means for assigning a separate authentication key (A-key) for each of said at least one MIN; means for displaying in said mobile station an indication of any one of said at least one MIN in response to a user-entered command; means for receiving in said mobile station a value of the A-key entered by the user for storing with the indicated MIN; means for validating the received value of the A-key through an authentication algorithm executed in said mobile station; means for storing in said mobile station the received A-key value with the indicated MIN if the received A-key value is determined to be valid; and means for receiving in said mobile station a new value of the A-key, entered by the user for storing with the indicated MIN or another MIN, if the received A-key value is determined to be invalid.
Claim 14
Independent Claim
174 words
A system for entering authentication information into a mobile station which is assigned at least one mobile identification number (MIN), said at least one MIN being stored in said mobile station, comprising: means for assigning a separate authentication key (A-key) for each of said at least one MIN; means for displaying in said mobile station an indication of any one of said at least one MIN in response to a user-entered command; means for receiving in said mobile station a value of the A-key entered by the user for storing with the indicated MIN; means for validating the received value of the A-key through an authentication algorithm executed in said mobile station; means for storing in said mobile station the received A-key value with the indicated MIN if the received A-key value is determined to be valid; and means for receiving in said mobile station a new value of the A-key, entered by the user for storing with the indicated MIN or another MIN, if the received A-key value is determined to be invalid.
