Hash key generation apparatus and method for multiple cards communication system

摘要

A mobile station is provided. The mobile station has a plurality of removable user identification modules, key generation logic, and hash logic. The plurality of removable user identification modules are each configured to store unique corresponding information associated with a corresponding plurality of cellular subscriptions. The key generation logic is configured generate a hash key. The hash logic is coupled to the key generation logic, and is configured to employ the hash key to determine parameters and attributes for continuing communication with a base station, where each of the parameters and attributes are determined to maximize use of common hardware and software within the mobile station to concurrently provide for communications in support of the corresponding plurality of cellular subscriptions.
