Patent ID: 8144703

Claim:
In a Global System for Mobile/Enhanced Data rates for a GSM Evolution (GSM/EDGE) compliant mobile radio network, a method to perform media or multimedia real-time transmissions of Radio Link Control/Multiple Access Control (RLC/MAC) protocol radio blocks to a higher protocol layer, the method comprising: setting up, by the network, resources for establishing at least a unidirectional Temporary Block Flow (TBF) of RLC/MAC radio blocks between two peers acting as RLC endpoints, each peer having a receiver that receives RLC/MAC radio blocks and a transmitter that transmits RLC/MAC radio blocks; transmitting RLC/MAC radio blocks over a radio interface from a transmitting peer within a transmit window; receiving RLC/MAC radio blocks by a receiving peer within a receive window and, in case of a not correctly received RLC/MAC radio block, sending back a ACK/NACK signaling message to inform the transmitting peer of reception failure; upon reception of the ACK/NACK signaling message, retransmitting from the transmitting peer, until expiration of the transmit window, the not correctly received RLC/MAC radio block; re-assembling the RLC/MAC radio blocks in sequence at the receiving peer; considering each RLC/MAC radio block as being permanently lost if not correctly received within the receive window; delivering all correctly received RLC/MAC radio blocks to the higher protocol layer; and transmitting, by the network, a notification message to both the transmitting peer and the receiving peer to select a size of the transmit and receive windows inside a range of predetermined values less than 64 RLC/MAC radio blocks.
