  • Patent number: 11832248
    Abstract: Apparatuses and methods in a communication system are provided. The solution comprises operating a radio access network, where the radio access network comprises two or more resource tiers, each tier having different latency/timing requirements. The resource allocation for the radio access network is realised (200) with two or more control loops, where each control loop is configured to allocate resources with different latency requirements, and control resources between the tiers. Resources of the inmost tier are controlled (202) by an inmost control loop with lowest latency resource allocation, and resources of the outer tiers are controlled (204) by one or more outer control loops for less latency critical resource allocation, each outer control loop having less critical latency requirement compared to loops closer to the inmost loop.

  • Patent number: 7653347
    Abstract: A Doppler compensation method is used for radio transmission between a mobile body possibly but not exclusively a train and some base station, both mobile body and base station comprise respectively a transceiver connected to an antenna for the radio transmission. The method comprises the step of determining the direction of motion of the mobile body with respect to the active base station i.e. the base station to which a radio transmission link is just built. The method is then followed by the step to apply a constant Doppler compensation corresponding to the cancellation of the Doppler effect for a mobile body moving in the same direction at predefined limiting speed of motion (vlimit) at which a quality threshold is reached with the used radio transmission technology in the case without a Doppler compensation.

  • Patent number: 7515539
    Abstract: A router which facilitates a simplified load balancing is provided. The router contains at least one buffer memory for the intermediate storage of pointers for information packets in at least two different buffer memory areas, a readout unit for reading out the different buffer memory areas one after the other in predetermined time windows, and at least one RED processing unit. A feedback loop is provided from the readout unit to at least one RED processing unit in order to control the activation and de-activation of the RED processing unit. Indirect information about the occupancy levels of the buffer memory areas is passed via the feedback loop to the at least one RED processing unit. The readout unit operates with the weighted round robin mechanism and transmits information about buffer memory locations processed in the time slots to the at least one RED processing unit.

  • Patent number: 7492781
    Abstract: The object of the invention is to create a router which has an enhanced processing speed. According to the invention, before access through a readout unit, the pointers for information packets stored in the buffer memory are arranged as required. If an overflow is imminent in a buffer memory area, for example, then individual pointers are selected and removed from the buffer memory area. The selected pointers are shifted into an additional buffer memory area, for example. This additional buffer memory area is then preferentially read out, so that the selected pointers are read out before the pointers in the buffer memory area. The criterion for the selection of a pointer is, for example, an expired reactivation time or a buffer memory area that is filled above a threshold value.

  • Patent number: 7346080
    Abstract: The invention relates to a procedure for the allocation of time slots for a transmission of data in variable time slots between a controller of a packet-oriented data network on the one hand and a terminal of a user of the data network on the other hand. The time slots are assigned to a terminal for a data flow following request made by the terminal and in dependence on the transmission capacity available in the data network, and are temporarily stored in a ring buffer before they are allocated to the terminal at a predefinable allocation instant. In order to simplify and accelerate the allocation of time slots in such a data network, it is proposed that a temporal write range be defined in the ring buffer by a variable first upper time threshold and a variable first lower time threshold.
