Systems and methods that request emergency services through an Internet-Protocol Television (IPTV) infrastructure. One embodiment comprises an IPTV network infrastructure comprising an IPTV server coupled to an IPTV set-top box of an end user that subscribes to IPTV services. The IPTV server receives a request for an emergency service from the end user through the IPTV set-top box. The infrastructure further includes a management server that receives the request for the emergency service from the IPTV server, and identifies information regarding the end user from an IPTV account of the end user. The infrastructure further includes a text message engine that receives the request for the emergency service from the management server, formats a text message for requesting the emergency service, inserts the information regarding the end user in the text message, and sends the text message to an emergency services center.

Requests for emergency services through an IPTV network

This invention provides the ability to load balance calls in a communications network using a certain criterion, such as a user-specified call priority, or the call service category. The method is applied when selecting a route for a new call or for re-balancing the calls across a network. When the user-specified call priority is used, the aggregated number of calls with the same priority or service category is calculated for all possible routes the new call may use. The aggregated number of calls is then divided by the number of hops in the respective routes; the route with the smallest ratio is selected for the new call. Re-balancing is performed by re-routing the calls in such a way as to obtain a similar number of calls of the same priority, or service category along all possible routes.

Multiple criteria based load balancing

This invention provides the ability to load balance calls in a communications network using a certain criterion, such as a user-specified call priority, or the call class of service. The method is applied when selecting a route for a new call or for re-balancing the calls across a network. When the user-specified call priority is used, the aggregated number of calls with the same priority or class of service is calculated for all possible routes the new call may use. The aggregated number of calls is then divided by the number of hops in the respective routes; the route with the smallest ratio is selected for the new call. Re-balancing is performed by re-routing the calls in such a way as to obtain a similar number of calls of the same priority, or class of service, along all possible routes.

Prioritized call load balancing

An emergency alert system for alerting DSL subscribers of imminent perils includes an alert server connected over a direct link to an edge node of a metro network for receiving an event notification, configuring from an event notification a highest priority alert message, and broadcasting the alert message to subscriber terminals over the metro network. An Add-Drop Multiplexer (ADM) multiplexes the alert traffic with the regular traffic onto the direct link, and the multiplexed traffic reaches the edge node of the metro network, which is configured with a high priority policy. The edge node discards the lower priority traffic in the presence of the alert traffic and an applet installed on the subscriber terminal accepts and displays the alert message in a browser or a media player.
