Abstract

A method for transmitting information includes: by a NodeB, receiving a message for setting up/reconfiguring a shared Enhanced Dedicated Channel (E-DCH) transmission channel from a Radio Network Controller (RNC); and setting up the shared E-DCH transmission channel according to parameters in the message, and exchanging information with the RNC through an established shared E-DCH transmission bearer. A system and NodeB for transmitting information are also provided. With the present invention, the NodeB and the RNC can share the E-DCH transmission bearer, thus saving the channel resources between the NodeB and the RNC while speeding up the information transmission between the RNC and the NodeB.

Claims

1. A method for transmitting information, comprising:

receiving, by a NodeB, a message for setting up/reconfiguring a shared Enhanced Dedicated Channel (E-DCH) transmission channel from a Radio Network Controller (RNC);

setting up, by the NodeB, the shared E-DCH transmission channel according to parameters in the message; and

exchanging information with the RNC through an established shared E-DCH transmission bearer.

2. The method of claim 1, wherein:

the parameters in the message, received by the NodeB, for setting up/reconfiguring the shared E-DCH transmission channel comprise;

relevant information about a signature list required when a User Equipment (UE) performs random access through the E-DCH; and

the information about the signature list comprises;

a serial number of a table corresponding to the signature list in a protocol;

or a signature sequence of the signature list.

3. The method of claim 1, wherein:

the parameters in the message, received by the NodeB, for setting up/reconfiguring the shared E-DCH transmission channel comprise;

relevant physical-layer channel parameters required when a User Equipment (UE) performs random access through the E-DCH; and

the relevant physical layer channel parameters are;

a format indication added in Arrest Indication Channel (AICH) information received by the NodeB from the RNC;

or

at least one of these items;

physical-layer parameters added in HS-SCCH information received by the NodeB from the RNC, High Speed-DSCH-related Shared Control Channel (HS-SCCH) format number added in HS-SCCH information received by the NodeB from the RNC, and HS-SCCH time sequence relation added in HS-SCCH information received by the NodeB from the RNC;

or

at least one of these items;

physical-layer parameters added in HS-PDSCH information received by the NodeB from the RNC, High Speed Physical Downlink Shared Channel (HS-PDSCH) time sequence relation added in HS-PDSCH information received by the NodeB from the RNC, and transmission channel parameters added in HS-PDSCH information received by the NodeB from the RNC.

4. The method of claim 1, wherein:

the parameters in the message, received by the NodeB, for setting up/reconfiguring the shared E-DCH transmission channel comprise at least one of these items;

relevant E-DCH physical-layer parameters required when a User Equipment (UE) performs random access through the E-DCH, transmission channel parameters required when a User Equipment (UE) performs random access through the E-DCH, and transmission bearer parameters required when a User Equipment (UE) performs random access through the E-DCH.

5. The method of claim 4, wherein:

the relevant E-DCH physical-layer parameters are added by the RNC in the process of setting up a common transmission channel.

6. The method of claim 4, wherein:

the transmission channel parameters are indicated by the RNC which is required for performing random access through the E-DCH in reconfiguration of a physical shared channel;

or

the transmission channel parameters are added by the RNC in the process of setting up the common transmission channel.

7. The method of claim 4, wherein

the transmission bearer parameters are added by the RNC in the process of setting up the common transmission channel.

8. The method of claim 1, further comprising:

returning, by the NodeB, information about the established shared E-DCH transmission channel to the RNC, wherein the information comprises a transmission layer address and/or a binding ID.

9. The method of claim 1, wherein:

the exchanging information with the RNC through an established shared E-DCH transmission bearer comprises;

adding, by the NodeB, a UE ID into the information sent by the UE, and converting data in the information into E-DCH data carrying the UE ID, or converting the data into an Frame Protocol (FP) frame carrying the UE ID, and sending the modified information to the RNC through the shared E-DCH transmission bearer.

10. A system for transmitting information, wherein:
