A predetermined, recurringtime period is allocated to transmission of localized data specified for users of individualones of said plurality of sub-areas, and a transmission capacity of the data stream isdivided using said predetermined, recurring time period among adjacent sub-areas.Localized data is then transmitted during the predetermined, recurring time period usinga divided transmission capacity allocated to the respective sub-area.
