Abstract:
A method in a wireless communication system for communicating messages generated by a plurality of applications, some of the plurality of applications having an application identifier which can be associated with one of a plurality of codebooks for compressing and decompressing the messages, the method comprising:in a server the step of sending selected ones of the plurality of codebooks, along with selected application identifiers to be associated with the plurality of codebooks, to a client in preparation for communicating the messages; andin the client the step of receiving and storing the selected ones of the plurality of codebooks and the selected application identifiers in preparation for communicating the messages, andthe method subsequently comprising:in the server, in response to having a message to send to the client, the steps of:compressing the message according to a codebook associated with an application generating the message; andtransmitting, to the client, the message and the application identifier of the application; andin the client, in response to receiving the message and the application identifier, the steps of:identifying, from the application identifier, the application to receive the message and, hence, the codebook associated with the application, to use for decompressing the message; andprocessing the message according to the codebook, to decompress the message.
