A multicellular transmission apparatus in a mobile communication network, capable of preventing delay involved in reassembling short packets into fixed length packets (ATM cells), degradation of communication signals due to the delay, and reduction of the transmission efficiency involved in assembling the short packets into the fixed length packets. When low speed information transmitted from a telephone set (610) is converted into short packets by a communication data assemblers/disassemblers (402) in a mobile gateway switching center, followed by multiplexing of the short packets into the fixed length packets by fixed length packet assemblers/disassemblers (404), the short packets sent from a plurality of telephone sets are grouped for each destination node (a particular radio base station, for example) in the network, and are multiplexed into the fixed length packets belonging to the group bound for the destination of the short packets. This obviates the disassembling/reassembling of the fixed length packets at intermediate switching centers, thereby implementing an effective ATM switching system. <IMAGE> |
