Abstract:
1. A method, comprising: communicating packet header information; comparing, at a communication device, a current item list containing a plurality of current items of said packet header with a reference item list containing a plurality of reference items, wherein said comparing determines a difference between said current item list and said reference item list; determining a type of classification of the current item list based on said comparing the current item list and the reference item list, wherein said type of classification is based on at least one of: whether an item in said reference item list is in said current item list, whether said item is in said reference item list, and whether contents of said item in said current item list are the same as contents of said item in said reference item list; encoding information regarding said difference prior to sending said information from a first entity to a second entity, wherein encoding said information comprises a combination of at least one of the following: encoding information regarding a position of a newly added item to said reference item list, encoding information regarding which item in said reference item list is not in said current item list, and encoding information regarding content of at least one item in said reference item list; and using the determined type of classification to control the communication and compression of the packet header information, wherein the classification of the current item list associates the current item list with at least one of a plurality of different predetermined encoding schemes.
