• where a “Post Registration Cancelation” feature is enabled, delaying a cancelation of a currently registered VLR, the delay including:
• attempting to register the subscriber at an address of the requesting VLR;
• and
• maintaining a previously registered location of the subscriber at the database responsive to a failure to register the subscriber.
