摘要： A method of controlling admission and scheduling radio resources in a wireless systems such a WiMAX network includes the step of admitting service requests only if at the time of the service request the system is able to pre-allocate the amount of radio resources required to provide the service at the time instant the resources are required. The services are arranged in a set of Quality of Service (QoS) classes (UGS, ERT-VR, RT-VR, NRT-VR, BE) to which priorities are assigned. Admission control and radio resource scheduling is performed by sharing the radio resources available among the QoS classes as a function of the priorities, whereby the QoS classes having a lower priority (RT-VR) may utilize the amount of resources left unused by the classes having a higher priority (UGS, ERT-VR). Pre-allocating the radio resources involves the operation of pre-provisioning the time frames for serving a given user as a function of ideal service times at which the user should be served in order to maintain a constant information flow by taking the maximum tolerated jitter as a delay constraint. In the presence of a plurality of users pre-provisioned with different respective service time frames, the respective service time frames are combined in a common multi-frame. A pre-scheduling data structure is compiled with a list of CIDs and respective data grant sizes for each frame in the form of a multiframe wheel structure.

摘要： Real-time media or multimedia services in 3GPP GSM/EDGE-compliant mobile radio networks call for reducing the actual latency of transmissions. Resources are assigned by the network to set up or reconfigure a TBF associated to the uplink/downlink transmission of radio blocks from/to an MS. A 5-bit "Coding" field is configured in the header of the involved RLC/MAC messages to select the transmitting/receiving window size. An additional signalling bit, also called scaling bit, is asserted/negated according to two opportunities offered by the new MAC protocol to properly select the window size. Thanks to the introduction of the scaling bit a subdivision of the time windows for type of services is made possible. Non real-time services, e.g. file transfer, avail of standard window sizes for MSs with multistat capability, as reported in 3GPP TS 44.060, V7.3.0 (2006-01 ), Release 7, subclause 9.1.9, for EGPRS TBFs. Delay-sensitive services, e.g. media or multimedia real-time transmissions, avail of new window sizes with scaled down values remapped to start from 1 to (maximum) 64 RLC/MAC blocks. The scaling bit is asserted or negated by BSC accordingly. Both peer entities comprised in a TBF are receiving the RLC/MAC messages with the proper setting of the scaling bit and the 5-bit coding IF; these entities decode the scaling bit and behave accordingly. The behaviour consists of either assuming the standard window size or scaled window size addressed by the same predetermined 5-bit "coding" information element.

摘要： A method of managing radio resources for providing real time services such as conversational and streaming services in a GERAN/UTRAN network. The services are provided by means of application data packets that are exposed to delay in propagating over said network, The delay exhibits jitter, and the radio resources of the network are managed to maintain the delay jitter experienced by the application packets that maximum tolerated value. Preferably, the Quality of Service profiles of the real time services in question are supplemented by means of a parameter (MAJ) representative of the maximum tolerated jitter for the application packets delay.

摘要： An end to end fast signalling procedure is disclosed in order to improve standard RTP/RTCP transport protocols for the support of streaming services with in any kind of wireless and/or mobile networks, in particular for the introduction within GSM-GPRS. The streaming flow is expected to be sent from an Internet Service Provider (ISP) to Mobile Stations (MS). During fast signalling procedure, RTCP feedback messages are sent at a rate higher then the one expected in standard RTCP protocol. Fast signalling messages are made by upgraded Receiver Reports (FRR) intended to make the end to end QoS control mechanism able to react quickly to sudden changes in the available bandwidth that can occur at the radio interface.
