Abstract:
1. A radio communication system including: a plurality of base stations; a communication controller connecting the plurality of base stations with a communication network; and a content server connected to the communication network, wherein the plurality of base stations transmit same communication information to an access terminal at a same timing and the access terminal combines the communication information received from the plurality of base stations at the same timing, wherein each of the base stations includes a plurality of sectors, wherein a group of the sectors which transmit the same communication information at the same timing is determined and a group number is defined to identify the group, wherein each of the base stations includes a sector state managing table for storing a sector number for identifying a corresponding sector and the group number for identifying the group of the sectors which transmit the same communication information at the same timing, wherein, when a first base station receives a viewing request from an access terminal, the first base station establishes a path to the communication controller, obtains the communication information from the content server via the communication controller to start transmission of the communication information to the access terminal, and transmits a communication information transmission request to an adjacent base station by referring to the sector state managing table, the communication information transmission request including at least an ID of the communication information, an ID of the own sector, and the group number, and wherein for each adjacent sector, the adjacent base station containing the each adjacent sector receives the communication information transmission request, refers to the sector state managing table, if the group number to which the sector belongs is equal to the group number included in the communication information transmission request, the adjacent base station establishes a path to the communication controller, and obtains the communication information from the content server via the communication controller to start transmission of the communication information to the access terminal.
