Abstract
A classification application utilizing a table of connection numbers and associated TCP/IP applications is utilized for determining a wireless packet communication, quality of service level by decoding a connection number field of the compressed packet header. Packets carrying different connection numbers can be mapped to different Quality of Service planes. When a non-active TCP connection becomes active, the classification application detects and identifies the connection by reading the connection number field of a compressed TCP/IP header in a packet of the application. The classification application applies the appropriate Quality of Service level as determined from a user database and a list of available Quality of Service levels. If the connection has no table entry, the TCP/IP application is identified based on comparison to a pre-loaded table of port numbers and a new entry is created in the connection number table.
