Abstract

The invention relates to a method for providing measurements on a bit-rate provided to scheduled data having a guaranteed bit-rate and being transmitted on at least one dedicated uplink data channel by at least user equipment via a C-RNC. Further, the invention also relates to a method for initiating congestion control for scheduled data of at least one guaranteed bit-rate priority class in a mobile communication system. Moreover, the invention relates to a C-RNC as well as a serving radio network controller performing these methods. To enable the C-RNC within a mobile communication system to perform congestion control for uplink transmissions having a guaranteed bit-rate the invention suggests to provide the C-RNC with a bit-rate being provided to scheduled data of the guaranteed bit-rate priority class using common or dedicated measurement procedures. This provided bit-rate is evaluated and taken as a basis for deciding on whether congestion control for data of the priority class needs to be performed.

Claims

1. A method for receiving a measurement in a Universal Mobile Telecommunications System (UMTS) comprising user equipments (UEs) and a Node B connected to a controlling radio network controller, the method comprising:

sending from the controlling radio network controller to the Node B a measurement initiation request message for initiating a measurement on a provided bit-rate being provided to data for each priority class, and

receiving at the controlling radio network controller from the Node B and in response to the request message, the measurement on the provided bit-rate being provided to data for each priority class, said data being associated with the priority class and being transmitted on a dedicated uplink data channel by at least one of the user equipments.

2. The method according to claim 1, wherein the provided bit-rate is measured as a common measurement including the provided bit-rates per priority class for all of the user equipments in a cell.

3. The method according to claim 2, wherein a logical channel mapped on the dedicated uplink channel is associated with the priority class.

4. The method according to claim 1, wherein said at least one user equipment is in soft handover.

5. The method according to claim 1, wherein a logical channel mapped on the dedicated uplink channel is associated with the priority class and the measurement indicates the provided bit rate per priority class.

6. The method according to claim 1, wherein the priority class refers to a scheduling priority indicator or a logical channel priority.

7. The method according to claim 1, wherein the measurement is received together with a priority indicator indicating the priority class with which a logical channel mapped on the dedicated uplink channel is associated.

8. The method according to claim 1, wherein the dedicated uplink data channel is an Enhanced Dedicated Channel of a UMTS system.

9. The method according to claim 1, wherein the dedicated uplink data channel is an Enhanced Dedicated Channel of a UMTS system, and for each priority class, the Node B measures the provided bit rate as the total number of MAC-d protocol data unit (PDU) bits whose transmission over the radio interface has been considered successful by MAC-e in the Node B during a measurement period, divided by the duration of the measurement period.

10. A Node B for use in a Universal Mobile Telecommunications System (UMTS) comprising user equipments (UEs) and the Node B connected to a controlling radio network controller, the Node B comprising:

a receiving section configured to receive from the controlling network controller a measurement initiation request message for initiating a measurement on a provided bit-rate for each priority class,

a measuring section configured to measure a provided bit-rate being provided to data for each priority class, said data being associated with the priority class and being transmitted on a dedicated uplink data channel by at least one of the user equipments, and

a signaling section configured to signal a measurement on the provided bit-rate to the controlling radio network controller.

11. A controlling radio network controller for use in a Universal Mobile Telecommunications System (UMTS) comprising user equipments (UEs) and a Node B connected to the controlling radio network controller, the controlling radio network controller comprising:

a sending section configured to send to the Node B a measurement initiation request message for initiating a measurement on a provided bit-rate for each priority class, and

a receiving section configured to receive from the Node B, the measurement on a provided bit-rate being provided to data for each priority class, said data being associated with the priority class and being transmitted on a dedicated uplink data channel by at least one of the user equipments.
