1. An information delivery system that delivers a message through a telecommunications carrier, the message being information delivered from a service provider to users, comprising:
an ID federation information storage that stores ID federation information being information associating a user identifier for identifying users in a service provider and a user identifier for identifying the users in a telecommunications carrier which the users subscribe to; a delivery demand receiver that receives, from a service providing system administered by a service provider, contents of a message and a user identifier in the service provider as information indicating users to serve as a delivery target of the message; a delivery demand processor that determines which telecommunications carriers a group of users designated as a delivery target of the message subscribed to based on ID federation information stored in the ID federation information storage, and determines a telecommunications carrier to serve as a delivery request destination of the message to the group of users from the telecommunications carriers determined that the group of users subscribe to according to a predetermined condition for the group of users; and a delivery demand transmitter that transmits the contents of the message received by the delivery demand receiver and a user identifier in the telecommunications carrier of the group of users for which delivery request destination is the telecommunications carrier as information indicating a group of users to serve as a delivery target of the message to a delivery system of the telecommunications carrier determined as a delivery request destination by the delivery demand processor, wherein, as for a group of users who subscribe to a plurality of telecommunications carriers, the delivery demand processor determines any one telecommunications carrier among the telecommunications carriers which the group of users subscribe to as a delivery request destination of a message, wherein, as for a group of users who subscribe to a plurality of telecommunications carriers, the delivery demand processing unit determines a telecommunications carrier to serve as a delivery request destination according to priorities at a given point of time while changing priorities at predetermined timing along a preset sequence of the telecommunications carriers, and wherein, as for users who subscribe to a plurality of telecommunications carriers, the delivery demand processing unit randomly determines a telecommunications carrier to serve as a delivery request destination, so that “maximum number of message transmission” is not exceeded, the maximum number of message transmission being a maximum value for the number of messages a telecommunications carrier can transmits for a given group of users.
