Then, the base station / MCE (200) sets the multicast channel (S105) and transmits the MBMS data received in step S103 (S107). At this time, the UEs 100 in synchronization with the multicast channel receive the MBMS data transmitted in step S107.

On the other hand, the UE 100 executes the MBMS dedicated application (S109).

Next, the UE 100 accesses the advertisement APN designated as a default to the MBMS-only application (S111 and S113).

Next, the MME 400 checks subscriber information of the UE 100 from the HSS (not shown) (S115). In this case, the subscriber information includes a subscriber profile including age, age, hobby, and region information where the UE 100 is currently located.

Next, the MME 400 returns the subscriber information confirmed in step S115 to the L-GW 300 (S117).

Next, the L-GW 300 requests the advertisement server 700 with the subscriber information received in step S117 (S119).

Next, the advertisement server 700 requests the target advertisement by transmitting the subscriber information received in step S119 to the subscriber information management server 1000 (S121).

Then, the subscriber information management server 1000 extracts advertisement data corresponding to the subscriber information received in step S121 from the matching table as shown in Table 1 (S121) and transmits the advertisement data to the advertisement server 700 (S123).

Next, the advertisement server 700 transmits the advertisement data received in step S123 to the L-GW 300 (S125).

Next, the L-GW 300 establishes a unicast channel with the UE 100 (S127), and then streams the advertisement data received in step S125 to the UE 100 (S129).

Then, the UE 100 plays the advertisement data received in step S129 (S131).

In addition, the UE 100 determines whether the advertisement data reception is terminated (S133).

In this case, when the reception of the advertisement data is terminated, the UE 100 sets synchronization with the multicast channel for MBMS, that is, the multicast channel set in step S105 (S135).

Next, in step S135, the UE 100 receives MBMS data from the base station / MCE 200 through the multicast channel in which synchronization is set (S137), and plays the signal (S139).
