PURPOSE:To obtain a packet composing method in which a concerned frame structure is discriminated from each connection and user data are composed based upon it by identifying plural kinds of frame structures and composing a packet according to a concerned packet composing means. CONSTITUTION:The method is applied to a cell reception part of an ATM adaptation processing section. The adaptation processing section has the function of giving user data recovered by from an ATM cell received from an ATM layer through adaptation processing to a host layer. The adaptation processing section is made up of a frame structure identification means 3 identifying a concerned frame structure for each connection and a combination circuit 4 combining a packet from a received cell based on one or plural frame structures. Then plural packet composing methods are supported by selecting a concerned composition means for each connection. Furthermore, the composing means is discriminated based on the structure of the received cell, then the composing method is discriminated by the hardware. |
