A communication control device 100 initiates a session with a communication device by executing a sequence including a plurality of communication events. The communication control device includes: a scenario information accepting part 101 for accepting scenario information including sequence execution instruction information associated with a communication event, the sequence execution instruction information instructing to newly execute a sequence, and the sequence execution instruction information including synchronization information representing whether to synchronize a first sequence that is the newly executed sequence and a second sequence that is another sequence; and a scenario executing part 102 for, when the communication event associated with the sequence execution instruction information included by the accepted scenario information is executed while a certain sequence is being executed, newly executing a sequence based on the synchronization information included by the sequence execution instruction information.

A system, which is connectable to a first apparatus capable of data communication using a data communication protocol via a network where each session is managed by a session management protocol, includes: a connecting section which, if ID about the first apparatus exists in a storing section when a start instruction is received from the first apparatus, registers ID about a session corresponding to the start instruction in association with the ID about the first apparatus, and establishes a path enabling data communication for the first apparatus in the network using the session management protocol; and a providing section which, upon receiving the ID about the session from a second apparatus, transmits confirmation information according to the result of confirmation about whether the ID about the first apparatus is in association with the ID about the session.

A resource list server issues SUBSCRIBE requests for individual resources in a list upon receiving a SUBSCRIBE request for the list. Then, when the resource list server has received NOTIFY messages that indicate the status of the individual resources from a notifier for the resources, the resource list server sends NOTIFY messages to a subscriber that has a subscription for the list, which includes the resources. When the notifier has received a request for updating an existing subscription, the resource list server sends a NOTIFY message that includes no content to the subscriber.
