<p>PROBLEM TO BE SOLVED: To set a band efficiently in the case of transmission of information requiring a broad frequency band and to revise the band into a band desired by a transmission terminal equipment surely at a high speed. SOLUTION: In this communication network, plural communication paths are set by a path setting section 31 via a band split section 3 and a band integral section 12 among terminal equipments making communication. In this case, the path setting section 31 sets a band used for each communication path. The band split section 3 receiving a cell provides an output of the cell to each communication path based on the setting by the path setting section 31. On the other hand, the band integral section 12 arranges the sequence of cells to be received with revised orders and provides an output of arranged cells to a reception terminal equipment 14. When a transmission terminal equipment 1 desires to increase the frequency band width, the band width is reserved as much as possible less than the band width of increase request for any communication path and the band not reserved is reserved by other communication paths.</p> |
