Abstract
A server (112) sends (604) selected codebooks (226) and application identifiers (228) to be associated with the codebooks, to a client (122) in preparation for communicating messages. The client receives and stores (606) the selected codebooks and application identifiers. Subsequently, the server, in response to having a message to send to the client, compresses (708) the message according to a codebook associated with an application generating the message, and transmits (710) the message and an application identifier to the client. The client, in response to receiving the message and the application identifier, identifies (714), from the application identifier, the application to receive the message and, hence, the codebook associated with the application, to use for decompressing the message. The client then decompresses (716) the message according to the codebook.
