Abstract
A method and system for supporting voice over internet protocol (VoIP) service over a wireless communication network is disclosed. Data is encoded at the encoding rate specified by the controller to generate a VoIP packet. Among the encoded data, bits that are sensitive to errors and bits that are not sensitive to errors are identified, and error protection is performed separately by the medium access control layer and / or the physical layer. The header of the VoIP packet may be selectively compressed according to an instruction from the control device. For a partial range of sensitive bits, UDP (user datagram protocol) -Lite may be used. During the silence period, comfort noise may be generated by the receiving end without receiving a comfort noise packet from the transmitting end. If the VoIP packet does not fit the currently allocated radio resource, the VoIP packet may be fragmented.
