Abstract

A method for processing a common channel message in a CDMA communication system. The method includes mapping a signaling message generated in a Layer 3, a medium access control (MAC) message generated in a MAC sublayer and user data, to be transmitted over common channels to corresponding common logical channels; adding identifiers corresponding to common logical channels to the received signaling messages; processing the common logical channel identifier-added messages according to a common radio burst protocol using a single sequence number; and mapping the messages processed according to the common radio burst protocol to corresponding common channels.

Claims

1. A method for processing a message transmitted over a common channel in a code division multiple access (CDMA) communication system, comprising the steps of:

a) receiving at least one of a control message generated in Layer 3, a control message generated in a medium access control (MAC) sublayer and user data, to be transmitted over a common channel;

b) mapping the at least one of a control message generated in Layer 3, the control message generated in a MAC sublayer and user data to corresponding common logical channels;

c) adding a logical channel identifier to the at least one of the control message generated in Layer 3, the control message generated in a MAC sublayer and user data, wherein said logical channel identifier defines each of the mapped corresponding common logical channels;

d) processing the logical channel identifier-added messages according to a common radio burst protocol with a single sequence number; and

e) mapping the processed messages to a corresponding common physical channel.

2. The method as claimed in claim 1, wherein the step (c) comprises the steps of:

adding an automatic repeat request (ARQ) parameter including a message sequence number and an acknowledgement sequence number to the logical channel identifier-added message;

adding an address parameter including a control field for identifying a mobile station to the ARQ parameter-added message to identify a data transmitter or receiver; and

adding a message length field and a cyclic redundancy check (CRC) field to the address parameter-added message to frame the message.

3. The method as claimed in claim 2, wherein the common logical channel includes a common signaling channel, a common MAC channel and a common traffic channel.

4. The method as claimed in claim 2, wherein the common physical channel is one of a common control channel, a paging channel and an access channel.
