Abstract

Method for distributing multimedia public warning alerts in a mobile telecommunications network, including: creating an alert message by an emergency authority computer in the network, the message including a textual message and a multimedia object; sending by a content distributor server parameters for a content delivery session; sending by the computer the created message to the server; sending by the computer a request for a cell broadcast message to a cell broadcast center in the network, the message including the textual message and content delivery session parameters; broadcasting by the cell broadcast center the message through a radio access network; receiving by mobile user equipment in the network the message through the radio access network; setting up by the multicast content distributor server a transparent IP multicast session between the server and at least some of the user equipment; sending the multimedia object though the session to the user equipment.

Claims16

Dependent claims

A method for distributing multimedia public warning alerts in a mobile telecommunications network, comprising the steps of:

creating an alert message by an emergency authority computer in said network, said alert message comprising a textual message and at least one multimedia object;
sending by said emergency authority computer a request for a content delivery session from a multicast content distributor server in said network;
sending by said multicast content distributor server in response to said request for one or more content delivery session parameters for a content delivery session, said content delivery session parameters comprising a multicast IP address;
sending by said emergency authority computer the created alert message to the multicast content distributor server;
sending by said emergency authority computer a request for sending a cell broadcast message to a cell broadcast center in said network, said cell broadcast message comprising said textual message and said content delivery session parameters;
broadcasting by said cell broadcast center said cell broadcast message through a radio access network in said network;
receiving by a plurality of mobile user equipment in said network said cell broadcast message through said radio access network;
waking up said plurality of mobile user equipment and displaying by a public warning application on said plurality of mobile user equipment said textual message of said cell broadcast message on said plurality of mobile user equipment;
generating on at least a part of said plurality of user equipment by said public warning application a multicast join message using said content delivery session parameters and sending by said at least part of said plurality of user equipment said multicast join message to the multicast content distributor server through said radio access network;
setting up by the multicast content distributor server a transparent IP multicast session between the multicast content distributor server and said at least part of said multitude of user equipment;
and
sending said at least one multimedia object though said transparent IP multicast session to said at least part of said multitude of user equipment.

9 more elements

A system for distributing multimedia public warning alerts in a mobile telecommunications network, comprising:

an emergency authority computer in said network;
a multicast content distributor server in said network;
a multitude of user equipment in said network, said user equipment being provided with a public warning application;
wherein said emergency authority computer is arranged to create an alert message, said message comprising a textual message and at least one multimedia object, and to send a request for a content delivery session from said multicast content distributor server;
wherein said multicast content distributor server is arranged to send in response to said request for one or more content delivery session parameters for a content delivery session, said content delivery session parameters comprising a multicast IP address;
wherein said emergency authority computer is arranged to send the created alert message to the multicast content distributor server;
and a request for sending a cell broadcast message to a cell broadcast center in said network, said cell broadcast message comprising said textual message and said content delivery session parameters;
said cell broadcast center being arranged to broadcast said cell broadcast message through a radio access network in said network;
wherein said plurality of mobile user equipment is arranged to receive said cell broadcast message through said radio access network;
wherein said public warning application is arranged to wake up said user equipment and display said textual message of said cell broadcast message on said user equipment;
to generate on said user equipment a multicast join message using said content delivery session parameters and to send said multicast join message to the multicast content distributor server through said radio access network;
and
wherein the multicast content distributor server is arranged to set up a transparent IP multicast session between the multicast content distributor server and at least part of said multitude of user equipment that sent said multicast join message;
and to send said at least one multimedia object though said transparent IP multicast session to said at least part of said multitude of user equipment.
