Abstract

A method, apparatus, and system for triggering resource configuration are disclosed. The method includes: if user equipment (UE) in Cell_Paging Channel (Cell_PCH) state figures out that the total amount of buffer occupancy at the radio link control (RLC) layer or the Transport Channel Traffic Volume is larger than configured threshold, the UE carries an indication in a MEASUREMENT REPORT message and transmit the message to the network side, wherein the indication is used to trigger the network side to configure resources for the UE. With the present invention, the resource configuration is quickly triggered, and the delay of the UE in the data transmission is minimized.

Claims

1. A method for triggering resource configuration, comprising:

by user equipment (UE) in Cell_Paging Channel (Cell_PCH) state, if figuring out that a Transport Channel Traffic Volume of the UE or total amount of buffer occupancy at a radio link control (RLC) layer of the UE is larger than a configured threshold, carrying an indication in a MEASUREMENT REPORT message and transmitting the message to the network side, wherein the indication is used to trigger the network side to configure resources for the UE.

2. The method of claim 1, wherein, the step of carrying the indication in a MEASUREMENT REPORT message comprises:

setting, by the UE, the indication in the MEASUREMENT REPORT message if the Transport Channel Traffic Volume or the total amount of buffer occupancy at the RLC layer of the UE is larger than the configured threshold;

setting, by the UE, an indication identifier in the MEASUREMENT REPORT message to true if the Transport Channel Traffic Volume or the buffer occupancy at the RLC layer of the UE is larger than the configured threshold, or else, setting the indication identifier to false;

or

setting, by the UE, an indication indicating that the UE complies with a 4a event in the MEASUREMENT REPORT message if the Transport Channel Traffic Volume of the UE is larger than the configured threshold.

3. The method of claim 1 or 2, wherein the indication is further used to identify the Transport Channel Traffic Volume of the UE or the buffer occupancy at the RLC layer of the UE.

4. User equipment (UE) for triggering resource configuration, comprising a processing module and a sending module, wherein:

the processing module is configured to;

carry an indication in a MEASUREMENT REPORT message transmitted to a network side if the UE is in Cell_Paging Channel (Cell_PCH) state and figures out that a Transport Channel Traffic Volume of the UE or total amount of buffer occupancy of a radio link control (RLC) layer of the UE is larger than a configured threshold, wherein the indication is used to trigger the network side to configure resources for the UE; and

send the MEASUREMENT REPORT message through the sending module.

5. A method for triggering resource configuration, comprising:

receiving, by a NodeB, a media access control packet data unit (MAC PDU) from a user equipment (UE), wherein the MAC PDU carries scheduling information, and the scheduling information comprises a numeric value of a total enhanced dedicated channel (E-DCH) buffer status (TEBS) field;

obtaining, by the NodeB, the numeric value of the TEBS field from the scheduling information in the received MAC PDU, and

sending, by the NodeB, an indication to a radio network controller (RNC) when the numeric value of the TEBS field is larger than a configured threshold, wherein the indication is used to trigger the RNC to configure resources for the UE.

6. The method of claim 5, further comprising:

sending, by the NodeB, an indication to the RNC when the numeric value of the TEBS field is smaller than another configured threshold, wherein the indication is used to trigger the RNC to configure resources for the UE.

7. The method of claim 5 or 6, wherein the indication further carries allocation and/or usage of common E-DCH resources on the NodeB.

8. The method of claim 5 or 6, wherein the threshold is configured by the RNC and sent to the NodeB.

9. A NodeB for triggering resource configuration, comprising a comparing module and a sending module, wherein:

the comparing module is configured to;

obtain a numeric value of a total enhanced dedicated channel (E-DCH) buffer status (TEBS) field from scheduling information carried in a media access control packet data unit (MAC PDU) sent from a user equipment (UE), and send an indication to a radio network controller (RNC) through the sending module when determining that the numeric value is larger than a configured threshold, wherein the indication is used to trigger the RNC to configure resources for the UE.

10. The NodeB of claim 9, wherein the comparing module is further configured to send an indication to the RNC through the sending module when determining that the numeric value is smaller than another configured threshold, wherein the indication is used to trigger the RNC to configure resources for the UE.

11. A system for triggering resource configuration, comprising a NodeB and a radio network controller (RNC), wherein:

the NodeB is configured to;

receive a media access control packet data unit (MAC PDU) from a user equipment (UE), obtain a numeric value of a total enhanced dedicated channel (E-DCH) buffer status (TEBS) field from scheduling information carried in the MAC PDU, and send an indication to the RNC when determining that the numeric value is larger than a configured threshold, wherein the indication is used to trigger the RNC to configure resources for the UE; and

the RNC is configured to configure resources for the UE after receiving the indication sent by the NodeB.

12. The system of claim 11, wherein the NodeB comprises a comparing module and a sending module, wherein:

the comparing module is configured to;

obtain the numeric value of the TEBS field from the scheduling information in the MAC PDU sent from the UE, and send an indication to the RNC through the sending module when determining that the numeric value is larger than the configured threshold, wherein the indication is used to trigger the RNC to configure resources for the UE.

13. The system of claim 12, wherein the comparing module is further configured to send an indication to the RNC through the sending module when determining that the numeric value is smaller than another configured threshold, wherein the indication is used to trigger the RNC to configure resources for the UE.
