Disclosed is a method for setting a common channel for a packet data service by an SRNC through a UE and a DRNC when the UE is handed over from a first Node B to a second Node B as the UE moves to the second Node B, in a mobile communication system. The SRNC transmits service parameters including bit rate information for the packet data service to the DRNC, and receives information on a common channel determined based on the service parameters from the DRNC. The SRNC transmits information on the determined common channel to the UE through the DRNC and the second Node B, to allocate the determined common channel to the UE.

What is claimed is: 1. A method for setting a common channel for a packet data service by an SRNC (Serving Radio Network Controller) to a UE (User Equipment) through a Node B and a DRNC (Drift Radio Network Controller) when the UE is handed over from a first Node B to a second Node B as the UE move
What is claimed is: 1. A method for setting a common channel for a packet data service by an SRNC (Serving Radio Network Controller) to a UE (User Equipment) through a Node B and a DRNC (Drift Radio Network Controller) when the UE is handed over from a first Node B to a second Node B as the UE moves to the second Node B, in a mobile communication system including the UE, the first Node B providing the packet data service to the UE, the SRNC connected to the first Node B, a CN (Core Network) connected to the SRNC, and the DRNC connected the second Node B neighboring the first Node B and also connected to the SRNC, wherein the CN has bit rate information for the packet data service and transmits the bit rate information to the SRNC, and the SRNC stores the bit rate information, the method comprising the steps of: transmitting service parameters including the bit rate information for the packet data service to the DRNC; receiving information on a common channel determined based on the service parameters from the DRNC; and transmitting information on the determined common channel to the UE through the DRNC and the second Node B, to allocate the determined common channel to the UE. 2. The method as claimed in claim 1, wherein the bit rate information includes a maximum bit rate and a guaranteed bit rate. 3. The method as claimed in claim 1, wherein the common channel is one of a common packet channel (CPCH), a random access channel (RACH) and a forward access channel (FACH). 4. A method for setting a common channel for a packet data service by an SRNC (Serving Radio Network Controller) to a UE (User Equipment) through a Node B and a DRNC (Drift Radio Network Controller) when the UE is handed over from a first Node B to a second Node B as the UE moves to the second Node B, in a mobile communication system including the UE, the first Node B providing the packet data service to the UE, the SRNC connected to the first Node B, a CN (Core Network) connected to the SRNC, and the DRNC connected the second Node B neighboring the first Node B and also connected to the SRNC, wherein the CN has bit rate information for the packet data service and transmits the bit rate information to the SRNC, and the SRNC stores the bit rate information, the method comprising the steps of: transmitting service parameters including bit rate information for the packet data service to the DRNC using an RNSAP (Radio Network Subsystem Application Part) message; receiving information on a common channel determined based on the service parameters through an RNSAP response message from the DRNC; and transmitting the determined common channel information to the UE through a radio resource control message, to allocate the determined common channel to the UE. 5. The method as claimed in claim 4, wherein the RNSAP message includes a common transport channel resources request message. 6. The method as claimed in claim 4, wherein the RNSAP response message includes a common transport channel resources response message. 7. The method as claimed in claim 4, wherein the bit rate information includes a maximum bit rate and a guaranteed bit rate. 8. The method as claimed in claim 4, wherein the common channel is one of a common packet channel (CPCH), a random access channel (RACH), and a forward access channel (FACH). 9. A method for setting a common channel for a packet data service by an SRNC (Serving Radio Network Controller) to a UE (User Equipment) through a Node B and a DRNC (Drift Radio Network Controller) when the UE is handed over from a first Node B to a second Node B as the UE moves to the second Node B, in a mobile communication system including the UE, the first Node B providing the packet data service to the UE, the SRNC connected to the first Node B, a CN (Core Network) connected to the SRNC, and the DRNC connected the second Node B neighboring the first Node B and also connected to the SRNC, wherein the CN has bit rate information for the packet data service and transmits the bit rate information to the SRNC, and the SRNC stores the bit rate information, the method comprising the steps of: determining service parameters including the bit rate information for the packet data service, determining a type of a common channel for transmitting packet data according to the determined service parameters, and then transmitting the determined service parameters and the determined common channel type to the DRNC; receiving information on the common channel determined based on the service parameters and the common channel type from the DRNC; and transmitting the received common channel information to the UE through the DRNC and the second Node B, to allocate the determined common channel to the UE. 10. The method as claimed in claim 9, wherein the bit rate information includes a maximum bit rate and a guaranteed bit rate. 11. The method as claimed in claim 9, further comprising the steps of: upon receiving the service parameters and the common channel type from the SRNC, determining by the DRNC whether the received common channel type represents a random access channel (RACH); determining a physical random access channel (PRACH) based on the service parameters, when the common channel type represents the random access channel; and transmitting information on the determined physical random access channel and the determined random access channel as the common channel information to the SRNC. 12. The method as claimed in claim 9, further comprising the steps of: determining by the DRNC a common packet channel (CPCH) set according to the service parameters, when the common channel type represents a common packet channel; and transmitting information on the determined CPCH set and an ID (Identification) of the determined CPCH set as the common channel information to the SRNC.
