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.

Abstract: The invention relates to a method for controlling by a base station the scheduling mode used by a mobile terminal for carrying out uplink data transmissions within a mobile communication network and to a base station performing this method. In order to provide a mechanism for scheduling mode switching on the network side the invention suggests to receive feedback for controlling scheduling of uplink data transmission between the mobile terminal and the base station, to estimate the buffer occupancy at the mobile terminal based on the feedback received, and to switch the mobile terminal from a scheduling mode presently used for uplink transmission to another scheduling mode based on the estimated buffer occupancy. In particular “rate up” requests in a rate controlled scheduling mode and buffer occupancy reports or traffic volume measurements may be used to estimate the buffer occupancy at the mobile terminal.

Abstract: A method for notification in communication systems is disclosed, in which a sequence of K notification indicators is assigned to a notification identifier like for example a MBMS service identifier or service group identifier of UMTS. The K notification indicators are transmitted one per frame in a cyclic manner. To obtain the notification indicator identifiers indexing the notification indicators in each frame, the plurality of notification identifiers is arranged in a K-dimensional space. Each of the K coordinates of this space can assume Nni values, where Nni is the number of notification indicators signalled per frame. The ith coordinate Xi,n of the point to where the nth notification sequence is mapped in the K-dimensional space, forms the identifier for the notification indicator belonging to the nth notification sequence in the frame with the frame number satisfying the equation i=M mod K.

Abstract: A method of controlling the data rate of transmitting data packets in a wireless communications system comprising transmitter communicating with at least one receiver by means of radio communication signals employing at least one automatic repeat request (ARQ) or a hybrid ARC protocol. The data packets are allocated to at least one logical channel which is mapped on at least one physical downlink communication channel for transmission from the transmitter to the receiver.

According to the invention, the data rate control is based on the receiver's current capability to process the amount of received data packets comprised in the communication signals. Further, the signaling information in the uplink feedback channel comprises a request to control the data rate in at least one logical channel.

Abstract: S-RNC 1060 determines the need for the combined radio link addition and serving HS-DSCH cell change based on received measurement reports, and makes a decision for starting an active set update and cell change procedure (process 1070). After that, it notifies immediately to source base station (Source Node B) 1050 that the decision on active set update was done (signaling 2). Source Node B 1050 transmits an ACTIVATION TIME NEGOTIATION REQUEST message (signaling 3) to S-RNC 1060. S-RNC 1060 transmits an ACTIVATION TIME NEGOTIATION RESPONSE message (signaling 4) to Source Node B 1050. Source Node B 1050 knows activation time through this, and ceases capacity assignment for transmitting data to UE 1030, while transmitting buffered packets to UE 1030 with a priority made higher than those of other UEs.

Abstract: A low profile, low volume smoke chamber displaces a light source, such as a light emitting diode or laser diode, and a sensor, such as photodiode or phototransistor, to the exterior of the sensing volume. A symmetrical sensing volume results which can be coupled to symmetrical input/output ports via a generally U-shaped flow path. A two part sensing chamber housing is formed with a lower cylindrical base portion and an upper cylindrical cover portion which slideably engage one another. At least the upper cylindrical portion carries a plurality of grooves for suppression of reflections and collection of dust. An exterior end of the upper portion carries a plurality of spaced apart openings which can be filled with a screen. A reduced sensing volume in combination with a selected screen size produces an acceptable signal to noise ratio and response rate while still excluding insects and other non-smoke related particulate matter.
