Abstract

A system and method for communicating data assigns priorities to different types of traffic based on one or more system conditions. The method includes classifying different kinds of traffic, allocating a priority to each kind of classified traffic, and when data received including different kinds of traffic multiplexing the traffic and the received data and transmitting the data according to the allocated priority. The traffic may be classified into signaling traffic, data traffic, and voice traffic. The data traffic may further be classified as follows: an RLP control frame, an RLP new frame, as well as other RLP frames. The voice traffic may be classified as full-rate voice traffic, half-rate voice traffic, quarter-rate voice traffic, and eighth-rate voice traffic. The method may be further controlled based on the type of multiplexing to be performed. Through this system and method, it is possible to provide good quality SVD (service simultaneous voice and data) by avoiding interruptions in transmissions.

Claims

1. A method of processing traffic in a mobile communication system, comprising:

classifying different kinds of traffic;

allocating a priority to each kind of classified traffic; and

when data is received including different kinds of traffic, multiplexing the traffic in the received data and transmitting the data according to the allocated priority.

2. The method of claim 1, wherein classifying the traffic includes:

classifying the traffic into signaling traffic, data traffic, and voice traffic and then classifying each of the data traffic and voice traffic.

3. The method of claim 2, wherein the data traffic is classified into at least a Radio Link Protocol (RLP) control frame and an RLP new frame.

4. The method of claim 3, wherein RLP control frame classifications include:

an RLP SYNC frame, an RLP SYNC ACK frame, an RLP ACK frame, an RLP NAK frame, and an RLP retransmission frame.

5. The method of claim 2, wherein voice traffic classifications include:

a full-rate voice traffic, a half-rate voice traffic, a quarter-rate voice traffic, and an eighth-rate voice traffic determined on the basis of an output rate of a vocoder.

6. The method of claim 1, wherein the priorities of the different kinds of traffic are set in order of signaling traffic, an Radio Link Protocol (RLP) control frame, full-rate voice traffic, a half-rate voice traffic, an RLP new frame, a quarter-rate voice traffic, an eighth-rate voice traffic, in response to a condition of a system except for the RLP control frame and the RLP new frame.

7. The method of claim 1, wherein said multiplexing the received traffic comprises:

storing traffic having a higher priority among the received traffic in a corresponding block of transmission traffic according to a preset multiplex type;

checking whether or not a reserved block exists within the transmission traffic;

if the reserved block exists, checking whether or not traffic having a lower priority exists among the received traffic; and

if the lower priority traffic exists, processing the lower priority traffic to have a size sufficient to be stored on the reserved block and storing the processed traffic on the reserved block of the transmission traffic.

8. The method of claim 7, wherein if the higher priority traffic is signaling traffic, the signaling traffic is stored in a signaling block of the transmission traffic, and according to a kind of the lower priority traffic a voice traffic is stored in a primary block of the transmission traffic after the voice traffic is processed to have a size sufficient to be stored on the reserved block and a data traffic is stored in a secondary block of the transmission traffic after processing the data traffic in order to have a size enough to be stored on the reserved block.

9. The method of claim 7, wherein if the higher priority traffic is data traffic, wherein the data traffic is stored in a secondary block of the transmission traffic and voice traffic, or the lower priority traffic is stored in a primary block of the transmission traffic, after the voice traffic is processed in order to have a size sufficient to be stored on the reserved block.

10. The method of claim 8, wherein the voice traffic is processed by controlling the output rate of the vocoder.

11. The method of claim 9, wherein the voice traffic is processed by controlling the output rate of the vocoder.

12. The method of claim 7, wherein if the higher priority traffic is a voice traffic, the voice traffic is stored in a primary block of the transmission traffic and a data traffic having a priority lower than the voice traffic is stored in a secondary block of the transmission traffic, after the data traffic is processed to have a size sufficient to be stored on the reserved block.
