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.

sending, by a radio network controller (RNC), a message for setting up or reconfiguring a shared enhanced dedicated channel (shared E-DCH) to a NodeB;

receiving, by the RNC, information from the NodeB about the shared E-DCH that the NodeB set up or reconfigured according to the message from the RNC to the NodeB;

exchanging, by the RNC, information with the NodeB through the shared E-DCH;

wherein the message from the RNC to the NodeB comprises the following parameters that are needed when a user equipment (UE) performs a random access procedure through the shared E-DCH;

a signature list, a relevant physical layer parameter, and a transmission bearer parameter;

and wherein the signature list is sent from the RNC to the NodeB in a same manner as sending a preamble signature in a physical random access channel (PRACH);

and wherein the exchanging information with the NodeB through the shared E-DCH comprises;

receiving, by the RNC, E-DCH data including a UE identity (ID) from the NodeB, and

resolving, by the RNC, the E-DCH data received including the UE ID to obtain the UE ID;

wherein the E-DCH data including the UE ID is obtained by adding, by the NodeB, the UE ID of a UE into information received from the UE and converting, by the NodeB, data and the UE ID in the information into the E-DCH data including the UE ID, wherein the information received from the UE does not include any UE ID.

2. The method of claim 1, wherein the information received from the NodeB comprises at least one of a transmission layer address and a binding identification (ID).

3. The method of claim 1, wherein the relevant physical layer parameter comprises:

5. The method of claim 1, wherein the transmission bearer parameter comprises the following items:

a binding identification (ID),

a transport layer address,

a common transport channel ID,

a transport format set, and

a TNL (transport network layer) QoS (quality of service).

6. The method of claim 1, wherein the parameters further comprise a relevant physical layer channel parameter;
