Abstract

A method and system for detecting and eliminating duplicate wireless mobile communications device Personal Identification Numbers (PINs) stored in user administration records associated with a server system is disclosed. The PIN of a wireless mobile communications device stored in a user administration record is checked against other existing user administration records, and if a duplicate of the PIN is detected, the PIN in one of the user administration records is reset. Duplicate PIN detection and elimination operations are preferably performed each time a new user administration record is created but may possibly be performed in response to selection of a particular user account, PIN or user administration record.

Claims

1. A computer-implemented method for detecting and eliminating duplicate wireless mobile communications device identifiers stored in user administration records associated with a server system, each of the user administration records including a wireless mobile communications device activation time, the method comprising the steps of:

receiving, at the server, information for registering a user account for a wireless mobile communications device; and

while the user account is pending to the server, wherein the user account is pending to the server when a corresponding user administration record has been added to the server but the wireless communication device has not been connected to a host system or network workstation to download required routing information, performing the steps of;

checking the identifier of the wireless mobile communications device stored in the user administration record against other existing user administration records to detect duplicate identifiers associated with different account holders; and

if a duplicate of the identifier is detected in one of the other existing user administration records, then comparing the activation time in the user administration record with the activation time in the one of the other existing user administration records, and resetting the identifier in the user administration record or the one of the other existing user administration records based on a result of the comparison of the activation times.

2. A method as recited in claim 1, wherein the step of resetting the identifier comprises resetting the identifier of the one of the other existing user administration records to a null value.

3. A method as recited in claim 1, wherein:

the server system maintains a separate list of identifiers for existing user records; and

the step of checking the identifier against other existing user administration records comprises checking the identifier against the list.

4. A method as recited in claim 1, wherein the step of resetting the identifier based on a result of the step of comparing comprises resetting the identifier in the user record having an earlier activation time.

5. The method of claim 1, further comprising assigning a new identifier to a device associated with the identifier that is reset.

6. A system for detecting and eliminating duplicate wireless mobile communications device identifiers in a communication system, comprising:

a data store configured to store user administration records, each user administration record being adapted to include a identifier and each of the user administration records including a wireless mobile communications device activation time; and

a server system configured to;

receive information for registering a user account for a wireless mobile communications device, and

while the user account is pending to the server, detect whether or not a identifier stored in the user administration record in the data store occurs in any other user administration record in the data store for a different account holder, and if so, to compare the activation time in the user administration record with the activation time in the one of the other user administration records, and reset the identifier in the user administration record or the one of the other user administration records based on a result of the comparison of the activation times, wherein the user account is pending to the server when a corresponding user administration record has been added to the server but the wireless communication device has not been connected to a host system or network workstation to download required routing information.

7. A system as recited in claim 6, wherein the server system resets a identifier by storing a null value to the user administration record.

8. A system as recited in claim 7, wherein the server system provides a message redirection service and is further configured to redirect messages from a host system to wireless mobile communication devices.

9. A system as recited in claim 6, wherein the wireless mobile communications device is selected from the group consisting of:

a mobile data communications device, a mobile voice communications device, a dual-mode communications device having both voice and data communications capabilities, a wireless mobile messaging client, a cellular telephone, a personal digital assistant (PDA) enabled for communications, a wireless modem, a one-way pager and a two-way pager.

10. The system of claim 6, further comprising a new identifier assigned to a device associated with the identifier that is reset.

11. A computer implemented method for detecting and eliminating duplicate wireless mobile communications device Personal Identification Numbers (PINs) stored in user administration records associated with a server system, each of the user administration records including a wireless mobile communications device activation time, the method comprising the steps of:

receiving configuration information for a new user account, the configuration information including a new user PIN;

determining whether the user account is pending to the server, wherein the user account is pending to the server when a corresponding new user administration record has been added to the server, but the new user has not yet connected the wireless mobile communications device to a host system or network workstation to download required routing information;

checking the new user PIN with a list of registered user accounts;

determining whether a duplicate PIN exists for an existing user account while the new user account is pending to the server, and if so, whether both user accounts are activated;

if no duplicate PIN exists or if both new and existing user accounts are not activated, then adding the new user account to the registered list;

if the duplicate PIN for the existing user account exists and both new user and existing user accounts are activated, then determining the most recently activated user account, and setting the PIN of the user account that is not the most recently activated to zero and notifying an administrator of the setting of the PIN to zero.

12. The method of claim 11, further comprising the steps of:

if the new user account is not pending to the server, then determining whether an activation time exists for the new user account;

if the activation time does not exist, then the setting the activation time for the new user account to the time of creation of the new user account configuration information.

13. The method of claim 12, further comprising the steps of:

if the new user account is pending to the server, then determining if a pending time exists;

if a pending time does not exist then setting the pending activation time for the new user account to the time of creation of the new user account configuration information.
