Abstract:
1. A wireless mobile communication system for transferring MBMS data from an access gateway to a plurality of wireless base stations and transmitting the MBMS data from the plural wireless base stations to a wireless mobile station at the same time, the system comprising: a transferring part included in the access gateway for copying the MBMS data in a number corresponding to the number of the plural wireless base stations, adding a header indicative of data transmission time to the MBMS data, and transferring the MBMS data to the plural wireless base stations; a transmitting part included in each of the plural wireless base stations for extracting the data transmission time from the header of the transferred MBMS data, deleting the header from the MBMS data, and transmitting the MBMS data to the wireless mobile station; wherein the MBMS data are transmitted to the wireless mobile station according to a difference between the data transmission time in the header and the time when the plural wireless base stations receive the MBMS data from the access gateway; wherein when the data transmission time is incorrect, the transferring part is configured to transfer the MBMS data added with another header including a corrected data transmission time, the MBMS data being transmitted in accordance with the corrected data transmission time included in the another header.
