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 first NOTIFY messages that indicate the status of the individual resources from a notifier for the resources, the resource list server sends second NOTIFY messages to a subscriber that has a subscription for the list, which includes the resources.

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.
