Abstract

A packet data generating method and apparatus for supporting multiple services in a wireless packet data communication system where an MS transmits two or more traffics to a BS on one of a reverse PDCH, a reverse FCH, and a reverse DCCH. To generate a PDU using non-signaling traffic and/or signaling traffic for one of the reverse physical channels, a multiplex option is determined during service negotiations between the MS and the BS. The multiplex option defines a traffic format having a header and a payload including traffic data, and the header includes a service reference identifier field, a length indicator field indicating the presence or absence of a length field, and the length field indicating the length of the traffic data. A PDU is generated by formatting a reverse traffic to have a header and a payload according to the determined multiplex option.

Claims

1. A method of generating a protocol data unit (PDU) using non-signaling traffic and/or signaling traffic in a wireless packet data communication system, comprising the steps of:

determining a PDU type between a mobile station (MS) and a base station (BS); and

generating the PDU by adding a header to a payload according to the PDU type, the header including a service reference identifier (sr id) field for identifying the service type of the traffic, a length indicator field indicating the presence or absence of a length field, and the length field indicating the length of the payload.

2. The method of claim 1, wherein the PDU generating step comprises the step of omitting the length field if the length indicator field indicates the absence of the length field.

3. The method of claim 1, wherein the length field is 0 or 4 bits.

4. The method of claim 1, further comprising the steps of:

generating a physical channel frame by connecting one or more PDU; and

transmitting the physical channel frame on a predetermined channel.

5. The method of claim 4, wherein the predetermined channel is one of a reverse packet data channel, a reverse fundamental channel, and a reverse dedicated control channel.

6. The method of claim 4, wherein the step of generating a physical channel frame comprises the step of generating the physical channel frame such that a last PDU does not contain the length field.

7. The method of claim 1, wherein the PDU type determining step comprises the step of, determining the PDU type using a multiplex option having a 3-bit MUXPDU type field for identifying a plurality of muxPDU types, a 3-bit format descriptor field, a 2-bit data block size field, a 6-bit max data blocks field, and a 2-bit rate set field.

8. The method of claim 7, wherein the multiplex option is greater than 0×

10.

9. The method of claim 7, wherein the multiplex option is one of 0×

1301, 0×

1302, 0×

1305, and 0×

1306.

10. The method of claim 7, wherein the multiplex option is formed to be

Number Field Name of Bits Value Rate_Set 2 ′

11. The method of claim 1, wherein the service reference identifier discriminates the signaling traffic and six different non-signaling traffic.

12. The method of claim 11, wherein the service reference identifier of the six non-signaling traffic set to “

001”

to “

110”

, respectively, and the non-signaling traffic set to “

000.

13. A method of generating a protocol data unit (PDU), in a wireless packet data communication system where a mobile station (MS) transmits two or more traffics to a base station (BS) on one of a reverse packet data channel (PDCH), a reverse fundamental channel (FCH), and a reverse dedicated control channel (DCCH), using non-signaling traffic and/or signaling traffic for one of the reverse physical channels, comprising the steps of:

determining during service negotiations between the MS and the BS a multiplex option, the multiplex option defining a traffic format having a header and a payload including traffic data, the header including a service reference identifier field, a length indicator field indicating the presence or absence of a length field, and the length field indicating the length of the traffic data; and

generating a PDU by formatting a reverse traffic to include a header and a payload according to the determined multiplex option.

14. An apparatus for generating a protocol data unit (PDU), in a wireless packet data communication system where a mobile station (MS) transmits two or more traffics to a base station (BS) on one of a reverse packet data channel (PDCH), a reverse fundamental channel (FCH), and a reverse dedicated control channel (DCCH), using non-signaling traffic and/or signaling traffic for one of the reverse physical channels, comprising:

a medium access control (MAC) layer for determining during service negotiations between the MS and the BS a multiplex option, the multiplex option defining the format of one traffic to have a header and a payload including traffic data, the header including a service reference identifier field, a length indicator field indicating the presence or absence of a length field, and the length field indicating the length of the traffic data, and generating a PDU by formatting a reverse traffic to have a header and a payload according to the determined multiplex option; and

a physical layer for generating a physical channel frame by connecting one or more PDUs according to the type and data rate of the reverse physical channel, and transmitting the physical channel frame on the reverse physical channel.
