    • The present invention relates to a mobile service and, more specifically, a method for enhancing mobile service quality when a broadcast failure or delay occurs in a wireless mobile terminal broadcast telecommunication system. A method for receiving a broadcast service according to the present invention comprises the following steps of: requesting a content server to transmit preliminary broadcast data or user customized data over a telecommunication network; receiving the requested data from the content server over a broadcast network or telecommunication network; and playing the received data when the playback of general broadcast data is delayed. According to the present invention, a broadcast video can continuously play although a broadcast failure occurs by playing a previously received video. Also, a channel delay time which a user feels can be reduced by providing user customized data. [Reference numerals] (AA) Start; (BB) End; (S100) Request preliminary broadcast data or user customized data (mobile communication network); (S120) Receive the request data (broadcast network or mobile communication network); (S140) Replay the received data when the playback of general broadcast data is delayed
