| 1. A method for communicating packets in a communication device having a wireless communication interface via a wireless network
to another communication device, comprising:
mapping, in a host controller interface, for a communication packet exchanged from a Logical Link Control Adaptation Protocol
(L2CAP) upper layer, the host controller interface between the upper layer and a physical layer, one of multiple connection
handles each identifying a respective service class requested by the communication packet to corresponding respective logical
channels in the upper layer such that each logical channel is mapped to a respective connection handle;
specifying, in a predetermined area of a payload header of a base band communication packet, the service class requested by
the communication packet which is exchanged from the upper layer;
determining said service class requested by said communication packet based on said payload header; and
distributing said base band communication packet to one of a plurality of buffers corresponding to said specified service
class depending upon said determining, and each of the plurality of buffers corresponding to a respective service class such
that each connection handle identifying the same service class is corresponded to the same buffer;
wherein the service class indicates a particular quality of service and includes at least one of a response speed preference,
a transmission delay preference, a distortion preference, a guaranteed particular band area, and a packet type.
