Abstract:
A subscription method based on session initiation protocol is disclosed. The method includes the steps of: receiving a subscribe request message sent by an proxy subscription entity instead of by a subscription entity, wherein said request message at least comprises: an event subscribed by the subscription entity and the uniform resource identifier (URI) of said subscription entity; sending a subscription confirmation notification to the subscription entity, according to the event subscribed by the subscription entity and the URI of the subscription entity in the subscribe request message of the alternate subscription entity; receiving a response sent by the subscription entity indicating that the subscription confirmation notification has been authenticated and establishing the dialogue between said subscription entities. A corresponding device is provided. The invention enables a proxy subscription entity to subscribe an event from an event notification entity on behalf of a subscription entity.
