Method of prioritizing frames transmitted on a signaling channel in a communication system, and, communication system providing a service that transmits user data on a signaling channel.

摘要

"METHOD OF PRIORIZING FRAMES TRANSMITTED IN A SIGNALING CHANNEL IN A COMMUNICATION SYSTEM, AND COMMUNICATION SYSTEM PROVIDING A SERVICE THAT TRANSMITS USER DATA IN A SIGNALING CHANNEL". In LAPDm, a short message service is implemented by pre-flushing every second signaling message when there is a short message to be sent. Even pre-flushing mechanism is also needed when the RLC / MAC protocol is used at the data binding layer instead of LAPDM. The mechanism is provided by defining at least two different identities to be used with frames transmitted on the signaling channel; and pre-emptying frames on the MAC at least on the basis of a frame's identity. Identities are preferably identified at the base of the frame signaling radio bearer.
