Abstract
A method for mapping CS voice data in a packet data channel is described. A CS plane voice data unit which includes a data unit header that has information indicative of a timestamp is generated. The data unit is transmitted over a packet data channel that introduces radio jitter (e.g., a packet switched data channel). The CS plane voice data unit is received and mapping of the data unit is provided based upon the timestamp information. The header may include information indicative of a SN. The timestamp information may be a part of an adaptation layer counter field and the SN may be a part of a packet data control protocol sequencing number field. Alternatively, the timestamp information a may be a part of a first protocol layer SN field and the SN may be a part of a second protocol layer SN field. Apparatus and computer programs are also described.
