<P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for efficiently distributing and storing access control clients within a network. <P>SOLUTION: In one embodiment, access clients include electronic subscriber identity modules (eSIMs), and an eSIM distribution network infrastructure is described which enforces eSIM uniqueness and conservation, distributes network traffic to prevent "bottle necking" congestion, and provides reasonable disaster recovery capabilities. In one variant, eSIMs are securely stored at electronic universal integrated circuit card (eUICC) appliances which ensure eSIM uniqueness and conservation. Access to the eUICC appliances is made via multiple eSIM depots, which ensure that network load is distributed. Persistent storage is also described, for among other activities, archiving and backup. <P>COPYRIGHT: (C)2013,JPO&INPIT |
