Abstract

When a voice incoming call occurs during multicast content playback, a control section interrupts multicast content playback after storing the multicast service execution status at that time point in a storage section. After a voice call is completed, the control section confirms whether or not the multicast content for which playback has been interrupted can be distributed at that location and, when distribution is possible, confirm whether or not the multicast content has been actually distributed. Then, if in distribution, the control section resumes multicast content playback.

Claims (23)

1 . A mobile station which receives and performs playback of multicast content transmitted from a base station, comprising:

a playback means for performing playback of multicast content transmitted from a base station;

an interruption detection means for detecting an interruption request pertaining to playback of multicast content by said playback means;

a storage means for storing multicast service execution status information at the same time point when a playback interruption instruction pertaining to multicast content has been detected by said interruption detection means;

an interruption means for interrupting playback of multicast content by said playback means;

an information acquisition means for acquiring multicast service information pertaining to multicast service currently available which is included in a message transmitted from a base station;

a resumption suitability determination means for determining multicast service resumption suitability based on multicast service information acquired by said information acquisition means and multicast service execution status information stored in said storage means after a multicast content playback interruption by said interruption means; and

a multicast service resumption means for resuming playback of multicast content by said playback means when judged that multicast service resumption is possible by said resumption suitability determination means.

2 . The mobile station according to claim 1 , wherein said execution status information includes content identification information for identifying said multicast content during reception and playback.

3 . The mobile station according to claim 1 , wherein said execution status information includes channel information for indicating channel on which said multicast content is being transmitted.

4 . The mobile station according to claim 1 , wherein said multicast service information includes content identification information for identifying said multicast content which said base station can distribute and distribution status information for indicating whether or not said multicast content is currently being distributed.

5 . A content replay method which receives and performs playback of multicast content transmitted from a base station, comprising the steps of:

storing multicast service execution status information at the same time point when a communication start request transpires while performing playback of multicast content transmitted from said base station;

interrupting playback of said multicast content;

acquiring multicast service information pertaining to multicast service currently available which is included in a message transmitted from a base station;

determining multicast service resumption suitability based on multicast service information and said multicast service execution status information acquired after completing said communication; and

resuming said multicast content playback when judged that multicast service resumption is possible.

6 . The content replay method according to claim 5 , further comprising the steps of:

discriminating whether or not said base station can possibly distribute said multicast content for which playback has been interrupted to provide a discrimination result after completing said communication; and

judging said multicast service resumption based on said discrimination result.

7 . The content replay method according to claim 6 , further comprising the steps of:

transmitting said multicast content distribution request to said base station when said base station discriminates that distribution is possible of said multicast content for which playback has been interrupted and not yet distributed; and

resuming playback of multicast content after completing said communication.
