Abstract

A method for transporting/receiving notification messages via File Delivery over Unidirectional Transport (FLUTE) includes: At the transmitting end, a server carries a notification content in a transport object and carries notification related information and a transport object identifier (TOI) of the transport object carrying the notification content in a first file description table (FDT), and then sends the first FDT and the transport object carrying the notification content in a FLUTE session; the receiving end obtains the notification related information and the TOI of the transport object carrying the notification content from the first FDT, and receives the transport object carrying the notification content according to the obtained related information and the TOI. A server for transporting notification messages via FLUTE, a FLUTE server, a content server and a terminal are also disclosed. With the present invention, the notification transport procedure is simpler and the reliability of notification transport is better.

5. The method of claim 1, comprising:

pre-adding a Notification element in a FDT-Instance element of the first FDT to indicate that a corresponding transport object carries a notification message;

in the Notification element, adding a TOI attribute, and adding a Notifi element to carry the notification related information, wherein carrying the notification related information and the TOI of the transport object that carries the notification content in the first FDT includes;

carrying the Notification element in the FDT-Instance element, setting the TOI attribute to a TOI of a transport element that carries a notification content, and carrying the notification related information in the Notifi element.

6. The method of claim 5, wherein adding the Notifi element includes adding a sub-element that carries header information of the notification message and a sub-element that carries header extension information of the notification message;

and

wherein carrying the notification related information in the Notifi element includes carrying header information of the notification related information in the sub-element that carries header information of the notification message and carrying header extension information of the notification related information in the sub-element that carries header extension information of the notification message.

7. A method for receiving a notification message via File Delivery over Unidirectional Transport (FLUTE), comprising:

obtaining notification related information and a transport object identifier (TOI) of a transport object that carries a notification content from a first file description table (FDT); and

receiving the transport object that carries the notification content in a current FLUTE session according to the obtained notification related information and the TOI.

8. The method of claim 7, wherein the first FDT is a special FDT pre-added in the current FLUTE session;

and the special FDT is carried in a transport object corresponding to a preset TOI, which value is any positive integer.

9. The method of claim 8, further comprising obtaining a preset TOI value before obtaining notification related information and the TOI of the notification transported in the current FLUTE session from the first FDT.

10. The method of claim 7, wherein obtaining notification related information of a notification being transported in a current FLUTE session from a first FDT includes determining that a Content-Type attribute of a FILE element of the first FDT is Notification and obtaining a Notifi element in the FILE element of the first FDT as notification related information.

11. The method of claim 7, wherein obtaining notification related information of a notification being transported in a current FLUTE session and a TOI of a transport object that carries a notification content from a first FDT includes determining that the first FDT carries a Notification element, obtaining a value of a TOI attribute in the Notification element as the TOI of the transport object that carries the notification content, and obtaining a Notifi element in the Notification element as notification related information.

12. The method of claim 7, further comprising screening, after obtaining notification related information of a notification being transported in a current FLUTE session, the notification being transported in the current FLUTE session according to the obtained notification related information to determine a TOI corresponding to a notification message to be received, wherein receiving the transport object that carries the notification content in the current FLUTE session according to the obtained related information and the TOI includes receiving a transport object corresponding to the determined TOI in the current FLUTE session.

13. The method of claim 12, wherein the obtained notification related information includes an ID of the notification, a version of the notification and a service ID of the notification, and wherein screening the notification according to the obtained notificationrelated information includes determining whether the notification is a notification service that a terminal cares about according the service ID of the notification and if not, screening a next notification;

if so, determining whether a transport object corresponding to the notification is received according to the ID of the notification and if the transport object is not received, determining the notification as a notification to be received and screening a next notification; and
