METHOD AND SYSTEM FOR IDENTIFYING ENCODING/DECODING INFORMATION IN A MOBILE RADIO NETWORK

摘要

A method and system for operating a mobile radio network in a packet switched mode in which a PCOMP index and a DCOMP index are separately used to specify identification values regarding encoding of data for transmitting so as to allow a receiving end to decode the data according to the identification values. The method comprises the steps of providing an OPT index representative of the PCOMP index and the DCOMP index, and providing an OPT field in the transmitted data, for conveying the OPT index to the receiving end. Preferably, the OPT field is extendable to specify other identification values for encoding/decoding, if a further index is used to specify such values.
