Radio link protocol (RLP)/point-to-point protocol (PPP) design that passes corrupted data and error location information among layers in a wireless data transmission protocol

A method for processing multimedia in a Point-to-Point Protocol (PPP) layer of a wireless packet network, said method comprising the steps of:

• receiving erasure data frames with said multimedia data from a Radio Link Protocol (RLP) layer;
• replacing said erasure data frames with a predefined binary value;
• and
• forwarding a packet payload to a higher layer if a valid header is received even if said packet payload is not properly received.

A system for processing multimedia data in a Radio Link Protocol (RLP) layer of a wireless packet network, said system comprising:

• a memory for storing computer readable code;
• and
• a processor operatively coupled to said memory, said processor configured to:
• process said multimedia data to determine if said multimedia data is properly received;
• forward erasure data frames with said multimedia data to a Point-to-Point Protocol (PPP) layer;
• and
• forward a location indicator of said erasure data frames to said PPP layer.

A system for processing multimedia data in a receiver of a wireless packet network, said receiver conforming to an open system interconnection (OSI) model, said OSI model having a plurality of layers including a Radio Link Protocol (RLP) layer, a set of interface layers and a User Datagram Protocol (UDP) layer, said system comprising:

• a memory for storing computer readable code;
• and
• a processor operatively coupled to said memory, said processor configured to:
• processing said multimedia data to determine if said multimedia data is properly received;
• and
• communicating error information between said RLP and UDP layers, wherein said RLP layer forwards an indication of a location of erasure data to said UDP layer.
