1. A method for processing circuit switched (CS) domain service data over a radio bearer, 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 enhanced dedicated channel (E-DCH);
wherein the speech frame comprises;
Frame Type, Payload, and Padding, wherein the Frame Type has a fixed length and represents an AMR/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.

Abstract
A method for bearing CS-domain service data over radio bearer is disclosed. The method includes: letting CS-domain service data be borne over a radio high-speed packet data access channel according to a channel mapping relation between CS-domain service data and the radio high-speed packet data access channel. An apparatus and a system are also provided herein.
