Claim:
1. A method for processing Circuit Switched domain (CS-domain) service data, wherein the CS-domain service data includes a speech service data comprising substreams A, B, and C with different importance classes, the method comprising: encapsulating the substreams A, B, and C into a single speech frame; mapping the speech frame onto a single radio bearer (RB); encapsulating the RB with radio link control (RLC) protocol; mapping the RLC to a dedicated traffic channel (DTCH); and mapping the DTCH to an High Speed Download Packet Access (HSDPA) downlink shared channel (HS-DSCH); wherein the speech frame comprises: Frame Type, Payload, and Padding, wherein the Frame Type has a fixed length and represents an Adaptive Multi-Rate (AMR) or Adaptive Multi-Rate Wideband (AMR-WB) coding mode, the payload is a data made up of the concatenated substreams A, B and C, and the padding is a filler bit, when a sum of the frame type and the payload is out of alignment against bytes, several bits are used as a padding to make the whole speech frame aligned against bytes.
