A method and apparatus for transmitting delay sensitive information (DSI) and non-delay sensitive information (NDSI) over a communication link where the NDSI is fragmented in an efficient and intelligent manner and the fragmentation is based on parameters of received DSI so as to reduce the likelihood of transmission conflicts between the DSI and the NDSI. DSI and NDSI are thus interleaved over the communication link in an efficient manner. Both the NDSI and the DSI are transmitted in accordance with a network layer protocol.
