  • Publication number: 20180270786
    Abstract: Techniques are provided for protecting the privacy of user equipment during paging operations in a communication system. In one example, a method includes determining at a mobility management element of a communication system that a paging operation is to be initiated for given user equipment. The method further includes restricting the paging operation between the mobility management element and the given user equipment to use of a temporary identifier for the given user equipment. By not using a permanent identifier of the given user equipment during paging operations, the given user equipment is effectively non-trackable by malicious base stations and active/passive listeners.

  • Patent number: 10075878
    Abstract: A method for supporting multiple-input-multiple-output communications, user equipment and a computer program product are disclosed. The method comprises the steps of: determining whether an amount of data available for transmission that is greater than a maximum capacity of one the plurality of streams is below an associated threshold amount of at least another of the plurality of streams; and if so, preventing transmission of at least one of the plurality of streams. This helps to ensure that a stream is only used for transmission when the residual data is sufficient to warrant its use.

    Abstract: Proposed is a method to operate a user equipment in a radio access network for transmitting uplink payload. In a first step (24) a determination is made whether a cell of the radio access network is selected, wherein the determination of the first step (24) is based on first information (28). In a second step (34) a determination is made whether the cell which has been selected in the first step (24) is accessed via a first radio access scheme or a second radio access scheme, wherein the determination of the second step (34) is based on second information (38). In a third step (44a; 44b) the uplink payload (8) is transmitted via an uplink channel of the selected cell according to the radio access scheme selected in the second step (34).

  • Publication number: 20180254998
    Abstract: We disclose a cloud-computing system configurable to allocate cloud resources to application functions based on a performance model generated for some or all of such functions by monitoring the performance of an instance pool employed for their execution. In an example embodiment, a corresponding performance model is generated by iteratively forcing the instance pool, during a learning phase, to operate in a manner that enables a control entity of the cloud-computing system to adequately sample different sub-ranges of an operational range, thereby providing a sufficient set of performance data points to a model-building module thereof. The model-building module operates to generate the performance model using a sufficient set of performance data points and then provides the model parameters to the control entity, wherein the model parameters can be used, e.g., to optimally configure and allocate the cloud resources to the application functions during subsequent operation.

  • Patent number: 10069583
    Abstract: A method and system are provided for synchronizing local clocks more quickly in a telecommunication network using IEEE 1588. A network element that receives timing signals from one or more possible parent clocks considers a measure of the reliability of the timing signals contained in Announce messages from the parent clock or clocks. The clock uses this reliability information in selecting one of the possible parent clock or clocks to use as the actual parent clock. Once the selection is made, the clock adjusts the filtering characteristics applied to timing signals received from the selected parent clock. The adjustments reflect how confident the parent clock is as to how stable the timing information it provides has become. If the indication of reliability contained in Announce messages received from the parent clock indicates that the timing information is not very reliable, then a high filter bandwidth is used in filtering the timing signals.

    Abstract: A manner of managing congestion in a data-traffic network. In one embodiment a network node such as a bridge, switch, or router includes an AQM having a PI controller configured to calculate p? using the difference between Q and a Target Q, wherein p? is p0.5 and p is the probability that a received packet will be dropped or marked, and some drop decision functions are configured to indicate that the node should drop a received packet by comparing p? to two random values. A marking decision function may also be present and configured to indicate that the node should mark a received packet by comparing p? to one random value. A congestion control classifier, which is in some embodiments an ECN classifier, is also present to classify a received packet and facilitate making the proper dropping or marking decision.

  • Patent number: 10070463
    Abstract: A wireless telecommunications method, a computer program product and network nodes are disclosed. The wireless telecommunications network node method comprises on a failure to establish a connection after initiating a RACH procedure, repeatedly transmitting a RACH preamble signature using a defined set of resource blocks of an uplink channel. In this way, when a conventional RACH procedure fails to establish a connection with the network, a modified RACH procedure is instead initiated. This modified RACH procedure transmits a RACH preamble signature repeatedly using a repeating set of resource blocks which are repeatedly allocated from the uplink channel. This enables the RACH preamble signature to be repeatedly transmitted so that the energy from these repeated transmissions may be combined by the network in order to detect the presence of the RACH preamble signature transmitted by network nodes in a poor coverage area such as, for example, an MTC device located in a basement.
