DEVICE AND METHOD FOR RECEIPT/TRANSFER OF PACKAGED DATA USING A PREDEFINED LENGTH INDICATOR IN MOBILE COMMUNICATION SYSTEMS Russian patent published in 2009 - IPC H04L12/56 H04L29/06 

FIELD: physics, communications.

SUBSTANCE: invention deals with mobile communication systems. Proposed are a method and device enabling efficient radio resource utilisation due to reduced size of the protocol data unit (PDU) of the radio link control (RLC) level in a mobile communication system supporting voice services on top the packet network. At RLC level PDU RLC is generated without insertion of information indicative of the beginning and the end of a specific service data unit (SDU) or utilisation/non-utilisation of complement on the size required. At RLC level the length indicator (LI) field is inserted in the header to indicate inclusion of the SDU temporary segment into the PDU RLC data field.

EFFECT: resultant decrease of the amount of redundant data being generated in the course of packet data transmission enables efficient utilisation of the limited radio resource available.
