Abstract:
A method of controlling compression of data exchanged between two different network entities and a communications device, wherein said two different network entities comprise a first network entity and a second network entity comprising a foreign agent for said communications device, wherein said first network entity and said foreign agent comprise a processing unit capable of performing at least one data compression algorithm on said data, the method comprising the steps of:sending a message from said first network entity to said foreign agent instructing said foreign agent to either negotiate, or not negotiate, a data compression protocol with said communications device; in the event that said foreign agent is instructed to not negotiate a data compression protocol with said communications device, implementing a data compression algorithm on said data in said first network entity, and in the event that said foreign agent is instructed to negotiate a data compression protocol with said communications device, implementing a data compression algorithm on said data in said foreign agent and not implementing a data compression algorithm on said data in said first network entity, whereby only one of said first network entity and said foreign agent performs a data compression algorithm on said data, under the control of said first network entity, thereby saving processing power in the network entity that does not implement a data compression algorithm on said data.
