Abstract: In a method of receiving augmenting content, broadcast content and augmenting content are received from a broadcast content providing apparatus, metadata related to the broadcast content is interpreted to check an indicator indicating such that augmenting content are applicable, and augmenting content are requested from an augmenting content providing apparatus by using access information of the augmenting content providing apparatus. Thereafter, augmenting content are received from the augmenting content providing apparatus, and augmenting content received in the augmenting content receiving step are synchronized with the broadcast content and output to a temporal/spatial region corresponding to display region information included in the metadata or the display region information is transmitted to a separate output device. Thus, a viewer can conveniently receive area information-based augmenting content in the form of large capacity multimedia including a graphic image or video without having to perform searching.

Abstract: A traffic distribution method through a multi-access network in a network and a network entity performing the same are disclosed. An access and mobility management function (AMF) may receive a PDU session modification request message including an ATSSS (access traffic steering, switching, and splitting) preference, which is a preference for an ATSSS rule, from an user equipment (UE) when a multi-access PDU session (MA PDU session) is established and the UE desires to change the ATSSS rule corresponding to the established MA PDU session. The AMF may transmit a first message including the ATSSS preference to a session management function (SMF).

Abstract: Provided is a random backoff apparatus and method for receiving augmented content that may prevent a delay or a down of a server caused by a plurality of receiving terminals accessing a server simultaneously, when a digital broadcasting system provides broadcast-based bidirectional broadcasting services over a communication network. That is, a technology for distributing receiving terminals accessing a server to receive augmented content, or accessing a home page of a corresponding program, based on metadata transferred from the digital broadcasting system to a broadcasting network. In a bidirectional digital method, a number of requests for access to the home page or the augmented content related to the program may be received from receiving terminals at one time. Accordingly, there is a desire for a method of preventing collision caused when a plurality of stations simultaneously access a single wireless channel.
