  • Publication number: 20230224221
    Abstract: To dynamically allow chaining of logical processing units comprising endpoints, at least a type of an endpoint, and address information whereto connect the endpoint is configured, wherein the type of the endpoint is either a host port type or a logical processing unit type. During offloading from a central processing unit one or more functions to be performed by at least one further processing unit, the central processing unit is interacting with the one or more logical processing units via endpoints of the host port type and logical processing units are interacting via endpoints of the logical processing unit port type, the interaction using the address information.

  • Patent number: 11323979
    Abstract: A broadcast manager identifies a time interval that encompasses paging windows for a plurality of user equipment. The plurality of user equipment operate according to a plurality of discontinuous reception cycles that include sleep intervals separated by the paging windows. The broadcast manager generates messages for wireless transmission to the plurality of user equipment in corresponding paging windows during the time interval. The messages include information indicating a transmission time at which the plurality of user equipment are to receive broadcast or multicast data. The transmission time is subsequent to the time interval.

  • Patent number: 11012504
    Abstract: Various exemplary embodiments relate to a method for determining whether to admit a query in a network, the method including determining a load for a network element type based on an adaptive history for that network element type; determining a cost of admitting the query based on the relative load that the query generates accounting for the amount of traffic the network element has admitted in the past; decreasing a total cost of all queries that can be budgeted during a subsequent interval when the change in load is within a specified range; increasing the total cost of all queries that can be budgeted during a subsequent interval when the change in load is below a threshold; and adding the query to a data structure which keeps track of potentially admittable queries.

  • Patent number: 10869220
    Abstract: There is provided a method and an apparatus performing the method, the method comprising monitoring one or more user equipment via a first interface; receiving network information from a transport layer element via a second interface between a network layer and a transport layer; determining, based at least on the monitoring of the one or more user equipment and the network information, congestion or degradation associated with the one or more user equipment; identifying a cause of the congestion or degradation associated with the one or more user equipment; and performing one or more action to mitigate or remove the cause of the congestion or degradation.

  • Patent number: 10542476
    Abstract: An agent is configured to receive queries from an application server in a communication network. The queries are directed to one or more devices in the communication network. The agent selects a communication path for a device from a plurality of communication paths from the application server to the device. The communication path is selected based on a data size that is to be sent to the device as part of the query, a number of devices that are to receive the query, or a combination thereof. The agent transmits the query via the selected communication path. The communication path can be selected based on one or more of a time criticality of the query, a subscription class of a user of the device, a category of a type of the device, an operator-defined influence factor, network conditions along the communication path, a broadcast flag in the query, or a combination thereof.

  • Patent number: 10484844
    Abstract: A service capability exposure function (SCEF) receives a short message service (SMS) message associated with a user equipment. The SCEF identifies a destination for the SMS message on the basis of a mapping between a unique identifier of the user equipment and an external identifier of the user equipment. The SCEF transmits the SMS message towards the destination. Receiving the SMS message and transmitting the SMS message are performed without establishing a packet data network (PDN) session for conveying the SMS message. A mobility management entity (MME) receives the SMS message and identifies the destination for the SMS message on the basis of a unique identifier of the user equipment included in the SMS message. The MME transmits the SMS message towards the destination.

  • Patent number: 10412624
    Abstract: A method includes receiving at least one current network condition factor (NCF), each current NCF indicating a level of congestion of a corresponding network. The method determines that there is an autonomous report to be transmitted and in response determines a policy entry of a policy used for autonomous reporting based on matching values of one or more input parameters related to the autonomous report to values of one or more input parameters of the policy entry. A reference NCF for a first network is determined from the corresponding policy entry. The method then determines whether to request to transmit the autonomous report on the first network based on a comparison of the reference NCF for the first network and the current NCF of the first network.
