A VoIP transmission typically includes “talkspurt” periods, during which VoIP packets are transmitted, and silence periods, which start with a silence indication (SID) packet and continue with periodic SID packets until a VoIP packet is received. When the base station is transmitting NRT data, the mobile device transmits CQIs to the base station at a first rate, with each CQI having a first fixed number of bits. When the base station is transmitting VoIP to the mobile device, then during a talkspurt period, the mobile device may transmit CQIs to the base station at a second rate slower than the first rate, and each CQI may have a second fixed number of bits less than the first fixed number of bits. However, during a silence period, the mobile device does not transmit CQIs to the base station, and uplink channel resources allocated for the CQIs can be reallocated to other mobile devices. | 2009-03-19 |
20090073959 | METHOD AND SYSTEM FOR VOICE-OVER-INTERNET-PROTOCOL (VoIP) TRANSMISSION IN A WIRELESS COMMUNICATIONS NETWORK - The invention is a method and system for reliably detecting the start and/or end of silence periods during voice-over-internet-protocol (VoIP) sessions in a wireless communications network. A VoIP session typically includes “talkspurt” periods, during which VoIP packets are transmitted, and silence periods, during which silence indication (SID) packets are transmitted. Both the base station (eNodeB or eNb) and the mobile device (user equipment or UE) may inspect the packets to identify them as VoIP or SID packets. Alternatively, only the eNB inspects the packets. The eNB then flags the first SID packet after a VoIP packet as the start of a silence period, and flags the first VoIP packet after a SID packet as the end of a silence period. The eNB then modifies the header of the medium access control (MAC) protocol data unit (PDU) prior to transmission to the UE. The UE then detects the modified MAC headers to identify the start and/or end of silence periods. | 2009-03-19 |
