Abstract (en)

[origin: WO2004017577A1] In a system in which multimedia data is compressed and broadcast or multicast to downlink, UTRAN is quickly transited to a full context formation state or a dynamic context formation state if plural terminals fail to form a full context or a dynamic context. Accordingly, the plural terminals can normally receive a header-compressed MBMS data in a U-mode of an ROHC technique.
