Method, apparatus, and system for triggering resource configuration
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.
1. A method for triggering resource configuration, comprising: receiving, by a NodeB, a media access control packet data unit (MAC PDU) being sent from a user equipment (UE) when the UE is in a Cell_Paging Channel (Cell_PCH) state, wherein a scheduling information is included in the MAC PDU, and the scheduling information comprises a numeric value of a total enhanced dedicated channel buffer status (TEBS) field;
comparing, by the NodeB, the numeric value of the TEBS field with a first configured threshold and a second configured threshold, and
sending, by the NodeB, an indication to a radio network controller (RNC) when the numeric value of the TEBS field exceeds the first configured threshold, wherein the indication is designated to trigger the RNC to initiate configuration of a dedicated transport channel for the UE;
sending by the NodeB, another indication to the RNC when the numeric value of the TEBS field is less than the second configured threshold, wherein the another indication is designated to trigger the RNC to reconfigure resources of the UE according to the another indication.
2. The method of claim 1 , wherein the threshold is configured by the RNC and sent to the NodeB.
3. The method of claim 1 , wherein the numeric value of the TEBS field represents the amount of data to be sent by the UE.
4. The method of claim 1 , wherein the numeric value of the TEBS field is used by the NodeB to collect at least one of a Transport Channel Traffic Volume of the UE and a total amount of buffer occupancy at a radio link control (RLC) layer of the UE.

the comparing module is configured to:
compare a numeric value of a total enhanced dedicated channel buffer status (TEBS) field with a configured threshold, wherein the numeric value of the TEBS field is included in a scheduling information within a media access control packet data unit (MAC PDU), the MAC PDU being sent from a user equipment (UE) when the UE is in a Cell_Paging Channel (Cell_PCH) state; and
the sending module is configured to:
send an indication to a radio network controller (RNC) when the numeric value of the TEBS field exceeds the configured threshold, wherein the indication is designated to trigger the RNC to initiate configuration of a dedicated transport channel for the UE.

7. The NodeB of claim 5 , wherein the numeric value of the TEBS field represents the amount of data to be sent by the UE.
8. The NodeB of claim 5 , wherein the numeric value of the TEBS field is used by the NodeB to collect at least one of a Transport Channel Traffic Volume of the UE and a total amount of buffer occupancy at a radio link control (RLC) layer of the UE.
9. A system, 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) being sent from a user equipment (UE) when the UE is in a Cell_Paging Channel (Cell_PCH) state, wherein a scheduling information is included in the MAC PDU, and the scheduling information comprises a numeric value of a total enhanced dedicated channel buffer status (TEBS) field;
compare the numeric value of the TEBS field with a first configured threshold and a second configured threshold, and send an indication to the RNC when the numeric value of the TEBS field exceeds the first configured threshold, wherein the indication is designated to trigger the RNC to initiate configuration of a dedicated transport channel for the UE; and send another indication to the RNC when the numeric value of the TEBS field is less than the second configured threshold, wherein the another indication is designated to trigger the RNC to reconfigure resources of the UE according to the another indication; and
the RNC is configured to:
initiate configuration of the dedicated transport channel for the UE after receiving the indication.
10. The system of claim 9 , wherein the first threshold is configured by the RNC and sent to the NodeB.
11. The system of claim 9 , wherein the numeric value of the TEBS field represents the amount of data to be sent by the UE.
12. The system of claim 9 , wherein the numeric value of the TEBS field is used by the NodeB to collect at least one of a Transport Channel Traffic Volume of the UE and a total amount of buffer occupancy at a radio link control (RLC) layer of the UE.
13. A system, comprising:
a user equipment (UE),
a NodeB, and
a radio network controller (RNC),
wherein the NodeB is configured to:
receive a media access control packet data unit (MAC PDU) being sent from the UE when the UE is in a Cell_Paging Channel (Cell_PCH) state, wherein a scheduling information is included in the MAC PDU, and the scheduling information comprises a numeric value of a total enhanced dedicated channel buffer status (TEBS) field;
compare the numeric value of the TEBS field with a first configured threshold and a second configured threshold, and send an indication to the RNC when the numeric value of the TEBS field exceeds the first configured threshold, wherein the indication is designated to trigger the RNC to initiate configuration of a dedicated transport channel for the UE; and send another indication to the RNC when the numeric value of the TEBS field is less than the second configured threshold, wherein the another indication is designated to trigger the RNC to reconfigure resources of the UE according to the another indication; and
