System and method for sharing a personal contact directory

摘要

A mobile communications network system includes a centralized data storage device and a plurality of wireless communication devices, wherein the centralized data storage device stores a personal contact directory of a first user that can be accessed by a second user. Preferably, the mobile communications network system further comprises a user verification module for granting access to the second user if the first user previously authorized the second user to have such access. The user verification module can authorize a user by verifying a unique identifier of the wireless communication device or a password inputted by a user.
