    Abstract: The present invention, in particular, refers to is a data packet ordering method in a mobile communication network employing hierarchical routing with data packet forwarding comprising the step of providing at least one data message encompassing a predefined sequence of data packets, forwarding at least one of said data packets of the sequence via a first network element over a first transmission path to a user equipment, whereby a part of the data packets are temporarily buffered in the first network element during transmission, establishing a second transmission path, while forwarding the data packet sequence, such that the remaining data packets of the sequence not yet transmitted over the first path are forwarded via a second network element, forwarding of the data packets buffered in the first network element to the second network element for providing all data packets comprised by the data packet sequence to the user equipment, receiving and ordering of the data packets within said second network element according to the packet data priority given by the data packet sequence, forwarding the ordered data packets to the user equipment.

    Abstract: A method of wireless telecommunication is provided. The method includes accessing a plurality of first data packets having a first size, accessing at least one second data packet having a second size, the second size being larger than the first size, forming a plurality of third data packets comprising portions of the at least one second data packet based upon the first and second sizes, and selecting at least one of the plurality of first data packets based upon the plurality of third data packets.

    Abstract: In a UMTS network in which a single user can transmit or receive a number of services having different transmission power requirements over a single channel, a method of determining for each service the number of bits to be punctured or repeated to provide rate matching by the steps of deriving for each service the Energy per Bit per Noise density EB/NO required to achieve a desired Bit Error Rate; from each EB/MO deriving a value of the Energy per coded Symbol per Noise density ES/NO; and from ES/NO deriving a rate matching factor by which that ES/NO can be matched to the minimum Energy per coded Symbol per Noise density applicable to the channel in which the services are multiplexed. The values of EB/NO are stored in a look up table in the BTS and each mobile; the BSC generates values of semi static rate matching factors and spreading factors for each service and transmits them to the BTS and mobiles so that the mobile can calculate from the received values and the values stored in the look up table the number of bits to be punctured or repeated.

    Abstract: The invention relates to the controlling of quality of services of a CDMA-based-System. An object of the invention is to provide an improved control mechanism for the quality of services in a CDMA-System, in particular by providing a controlling means apt to assign the target signal to interference ratio, the static rate matching factor and the power-offset dynamically, especially adapted to be used for UMTS-Systems. The invention proposes and uses a dynamic quality control for adjusting quality of services of a CDMA-based System transmitting a plurality of different services between the system and a user equipment by using at least one data channel (DPDCH) with the services multiplexed and rate matching technique applied and an associated control channel (DPCCH) wherein parameters representing transmitting properties concerning the quality of service, advantageously representing a signal to interference ratio (SIR) for the control channel (DPCCH), a static rate matching factor (SRF) for each service and a power-offset (G) between the control channel (DPCCH) and the data channel (DPDCH) are derived for each service to achieve desired quality of services, during an installation process based on default quality (1,2) requirements and during an operating condition dynamically in dependence of quality estimates (1,5) performed on each of that services during data transmission.

    Abstract: The invention relates to random access packet transmission in a packet switched mobile network. It is an object to provide a new and improved approach to avoid problems of overload handling for a random access packet transmission in packet switched mobile networks and in particular, to limit the transmit delay of at least some selected data flows even in case of a long-term overload situation. It is suggested to employ on a respective random access packet transmission channel an admission control functionality (1a, 2a, 3a, 4a, 5a) depending on a request for the adding of a new data flow and/or to employ on the respective random access packet transmission channel a congestion control functionality (1c, 2c, 3c) depending on varying environments.
