Patent ID: 7529237

Claim:
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.
