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.

bearing each channel of the CS-domain service data over the radio high-speed packet data access channel through one Radio Bearer, RB, channel, and

mapping the radio high-speed uplink packet data access channel.

3. The method of claim 2, wherein the CS-domain service data is speech service data, and the bearing the CS-domain service data through the RB channel comprises:

encapsulating multiple substreams into one speech frame if the speech service data comprises the speech service data; and

bearing the speech frame through one RB channel.

4. The method of claim 1, wherein the channel mapping relation is a first channel mapping relation, and the bearing the CS-domain service data over the radio high-speed packet data access channel comprises:

encapsulating each channel of the CS-domain service data into one data frame;

bearing the data frame over one RB channel; and

mapping the data frame to the radio high-speed uplink packet data access channel.

5. The method of claim 1, wherein the channel mapping relation is a second channel mapping relation, the CS-domain service data comprises multiple substreams, and the bearing the CS-domain service data over the radio high-speed packet data access channel comprises:

bearing each substream contained in the CS-domain service data over one RB channel; and

mapping to the radio high-speed uplink packet data access channel.

6. The method of claim 1, further comprising:

bearing CS-domain service data in a direction that needs to change bearer channel over a non high-speed packet data access channel according to a third channel mapping relation between the CS-domain service and the non high-speed packet data access channel when a status that the radio high-speed packet data access channel is adopted in both uplink and downlink directions changes to another status that the radio high-speed packet data access channel is adopted in one of the uplink direction and downlink direction and the non high-speed packet data access channel is adopted in the other direction.

7. The method of claim 1, further comprising:

bearing CS-domain service data in both uplink and downlink directions over a non high-speed packet data access channel according to a third channel mapping relation between the CS-domain service and the non high-speed packet data access channel when a status that the radio high-speed packet data access channel is adopted in both the uplink and downlink directions changes to another status that the non high-speed packet data access channel is adopted in both uplink and downlink directions.

8. The method of claim 1, further comprising:

bearing CS-domain service data in a direction that needs to change bearer channel over a non high-speed packet data access channel according to a third channel mapping relation between the CS-domain service and the non high-speed packet data access channel when a status that the radio high-speed packet data access channel is adopted in only one of uplink direction and downlink direction and the non high-speed packet data access channel is adopted in another direction changes to another status that the non high-speed packet data access channel is adopted in both the uplink and downlink directions.

9. The method of claim 1, further comprising:

bearing CS-domain service data in both uplink and downlink directions over the radio high-speed packet data access channel according to the channel mapping relation between the CS-domain service and the radio high-speed packet data access channel when a status that a non high-speed packet data access channel is adopted in both the uplink and downlink directions changes to another status that the radio high-speed packet data access channel is adopted in both the uplink and downlink directions.

10. The method of claim 1, further comprising:

bearing CS-domain service data in a direction that needs to change bearer channel over the radio high-speed packet data access channel according to the channel mapping relation between the CS-domain service and the radio high-speed packet data access channel when a status that the radio high-speed packet data access channel is adopted in only one of uplink direction and downlink direction and a non high-speed packet data access channel is adopted in another direction changes to another status that the radio high-speed packet data access channel is adopted in both the uplink and downlink directions.

11. The method of claim 1, further comprising:

bearing CS-domain service data in a direction that needs to change bearer channel over the radio high-speed packet data access channel according to the channel mapping relation between the CS-domain service and the radio high-speed packet data access channel when a status that a non high-speed packet data access channel is adopted in both the uplink and downlink directions changes to another status that another status that the radio high-speed packet data access channel is adopted in one of the uplink direction and downlink direction and the non high-speed packet data access channel is adopted in the other direction.
