Method and system for notifying subscriber devices in ISP networks

A computer system comprising a memory, a processor, and an interface of an internet service provider (ISP) network operator, the computer system being communicated with a subscriber local area network, the computer system further comprising:

• a contact database in the memory which stores a contact address of each subscriber device and identifications of notification mechanisms available for each subscriber device, and priorities and reliabilities of each notification mechanism;
• a query manager module verifying a contact address of a destination subscriber device and whether there are available notification mechanisms for the destination subscriber device in the contact database using an identity of the destination subscriber device, the query manager comprising sending means for sending a response indicating a state of a notification request to the interface of the ISP network operator;
• a detector module which comprises comprising:
• a discoverer for inventorying each subscriber device in the contact database by listening to the subscriber local area network,
• an analyzer for analyzing network traffic from the subscriber local area network and assigning a priority to each notification mechanism based on the analyzed network traffic,
• a creator for identifying notification mechanisms of each subscriber device inventored by the discoverer;
• and
• a notifier module selecting at least one notification mechanism from the available notification mechanisms when available notification mechanisms are identified by the creator and stored in the contact database for the destination subscriber device, and the notifier comprising sending means for sending a notification content to the contact address of the destination subscriber device using the selected notification mechanism;
• wherein the notifier module generates a notification message adapted respectively to each subscriber device;
• and
• wherein the creator estimates a trustability index for each notification mechanism by combining data regarding availability of each subscriber device inventored by the discoverer, frequency and traffic volume for each notification mechanism identified by the analyzer, and stores the trustability index in the contact database as the priority assigned to each notification mechanism available for each subscriber device.
