  • Patent number: 11317314
    Abstract: To handle network traffic, a Deep Packet Inspection (DPI) node receives, from a Policy and Charging Rules Function (PCRF) network node, packet inspection control data that maps a specific service to an identifier. The DPI node identifies that a data packet pertains to the specific service. The identifying comprises performing DPI on at least a data section of the data packet. The DPI node notifies the PCRF network node that the DPI node received the data packet and that the data packet pertains to the specific service. The DPI node marks the data packet with the identifier in accordance with the packet inspection control data received from the PCRF network node.

  • Patent number: 11223570
    Abstract: The present invention relates to a methods and network nodes for controlling resources of a service session in a communication network as well as to a corresponding system and computer program to improve the handling of resources in the network, and particularly to optimize signaling in the network. The method for controlling resources for a service session by a policy and charging system in a communication network comprises the steps of obtaining, at a first network node, a request including service session data indicating the type of service; determining, based on the service session data obtained at said first network node, a resource type to be assigned to said service; and sending to a second network node an indication of said resource type assigned to said service, according to which resource type it is determined when a service session associated with said service is terminated.

  • Publication number: 20210185697
    Abstract: For efficiently handling network traffic via a fixed access, classification of UL data traffic in a communication device may be accomplished in a reflective mode by detecting identifiers of outgoing uplink data packets which are complementary to identifiers of incoming downlink data packets. The downlink data packets are already assigned to the traffic classes. The outgoing uplink data packets carrying the complementary identifier are assigned to the same traffic class as the incoming downlink data packets. For this purpose, the communication device is provided with a traffic classificator. In the reflective mode, the traffic classificator locally generates uplink packet classification rules by monitoring received downlink data packets.

  • Patent number: 10785784
    Abstract: A service class for a transmission of data packets between a service entity and a user equipment is selected from a plurality of service classes. A first transmission context is established between a core network node and the user equipment, and is associated with a first set of attributes for defining a first quality of service for the transmission. Furthermore, a second transmission context is established between an access node and the user equipment, and is associated with a second set of attributes for defining a second quality of service for the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node.

  • Patent number: 10582411
    Abstract: A user equipment receives incoming data packets from one of a plurality of bearers. The incoming data packets comprise a first identifier indicating a source. The user equipment also detect outgoing data packets which include a second identifier indicating the source of the first identifier as destination of the outgoing data packet. The user equipment routes detected outgoing data packets which include the second identifier to the same bearer from which the incoming data packets having said first identifier are received. The detecting and routing is selectively activated on the basis of a control signal.

  • Patent number: 10511536
    Abstract: In a mobile communication environment, the data traffic is mapped to a number of bearers. In a downlink direction, this is accomplished by filtering data packets on the basis of an identifier which is included into the data packets in response to packet inspection. In the uplink direction, a mirroring function is applied which detects incoming data packets, which are received on one of a plurality of bearers and have a first identifier, and outgoing data packets having a second identifier which is complementary to the first identifier. The outgoing data packets having the complementary second identifier are routed to the same bearer from which the incoming data packets are received.

  • Patent number: 10464785
    Abstract: A step chain for driving steps of an escalator may include link plates, chain pins, chain bushes, and buffer rollers that are connected to one another to form chain links, which can be moved in relation to one another. The step chain may also include running rollers disposed outside the chain links. The buffer rollers may each be designed in the form of a multi-component part that comprises at least one inner, dimensionally stable sliding component, by way of which the buffer rollers can be arranged in a rotatable manner, respectively, on the chain bushes, and an outer, damping component that is designed to be more elastically deformable than the sliding component. The step chain may be utilized in a person-conveyor device, such as an escalator or a moving walkway, for example.

  • Patent number: 10044618
    Abstract: A node (36?; 50) generates messages to be sent to a policy controller (30). Further, the node (36?; 50) determines a load value. The load value represents a number of the messages which are sent from the node (36?; 50) to the policy controller in a given time interval. In response to the load value reaching a threshold, the node (36?; 50) limits sending of at least one of the messages to the policy controller.

  • Patent number: 9998343
    Abstract: For event reporting between a first node and a second node of a mobile telecommunications network, the second node sends an indication to the first node to subscribe to reporting of a certain event type by the first node. The indication may specify that a change in type of radio access technology, as used by a user equipment for connecting to the telecommunications network, is to be reported from the first node to the second node. The second node may provide additional information to the first node to further specify a subtype of the event to be reported. The additional information may specify at least one type of radio access technology. Based on detecting the event of the specified event type and subtype, e.g., a change to or from a specific type of radio access technology, the first node sends a report of the detected event to the second node.

  • Patent number: 9992288
    Abstract: A method in a communications network for adaptive handling of network data traffic between a user equipment and a network resource, said data traffic being enabled by a lookup procedure for obtaining a network address of the network resource. The user equipment sends to a server a request for accessing said data traffic. The server obtains access information related to a connection of the user equipment to the communications network and sends a further request to a lookup adaptation server. The source address of the further request is based on the access information. Based on the source address of the further request, the lookup adaptation server returns to the user equipment a network address of the network resource capable of handling the data traffic.
