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.

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.

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.

Abstract: In a mobile communication environment, the data traffic is mapped to a number of bearers (52, 54). 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 (52, 54) 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 (52, 54) from which the incoming data packets are received.

Abstract: Conveyors and people movers, such as escalators and moving walkways, for instance, may include a support member belt comprised of a plurality of support members guided on rails. The support members may be, for example, steps of an escalator or pallets of a moving walkway. Each support member may be secured to a pair of drag rollers that travels along the rails. Further, each support member may include a roller spindle that is held rotationally conjointly in or on a body of the support member. Between the roller spindle and the body of the support member, there may be a plug-in connection by way of which the roller spindle is maintained against an undercut under bias of a latching device.

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.

Abstract: For transmitting data between a node (100) of a mobile network and a further node (200), the further node sends downlink data packets to the node (100) of the mobile network. The downlink data packets carry a destination address corresponding to a user equipment (10) connected to the mobile network. For implementing an inband data channel between the node (100) of the mobile network and the further node (200), the further node (200) inserts data destined to the node (100) of the mobile network into at least one of the downlink data packets and marks this downlink data packet as including data destined to the node (100) of the mobile network. The node (100) of the mobile network receives the downlink data packets from the further node (200) and identities, on the basis of the marking, the least one downlink data packet including data destined to the node (100) of the mobile network. The node (100) of the mobile network then extracts the data from the identified downlink data packet.

Abstract: A policy controller of a mobile network receives an authorization request for a packet-based service from a node. In response to receiving the authorization request, the policy controller performs an authorization check to determine an authorization status of the service and sends an authorization response to the node. The authorization response indicates the authorization status of the service. In response to the same authorization request, the policy controller performs at least one further authorization check to redetermine the authorization status of the service. If the further authorization check indicates that the authorization status of the service has changed, the policy controller sends a status change message to the node. The status change message indicates to the node that the authorization status of the service has changed.

Abstract: User identity token for identifying a user of a communication network A first node (13), e.g., a policy controller of a communication network, receives a request (101) from a second node (15), e.g., an application server for providing a service in the communication network. The request (101) includes a transport address assigned to a user of the communication network. Further, the first node (13) accesses mapping data (31) relating the transport address to a subscription identity of the user and determines a user identity token which is mapped to the subscription identity of the user and masks the subscription identity. The first node (13) then sends a response to the second node (15). The response (102) includes the user identity token.

Abstract: Data traffic between a user at a user equipment and a network resource is preceded by a lookup procedure for obtaining a network address of the network resource. A message of the lookup procedure is processed depending on a class of users to which the user belongs. If the user belongs to a first class of users, the message of the lookup procedure is processed for adapting the lookup procedure to return a first network address of a replacement network resource capable of handling the data traffic. If the user belongs to a second class of users, the message of the lookup procedure is processed for adapting the lookup procedure to return a second network address of a replacement network resource capable of handling the data traffic.

Abstract: For handling user plane traffic in a communication network, a NAT node (100) determines a mapping between a network address (200-e) of a server (200) and a replacement network (200-i) address matching a packet classification rule implemented in the communication network. If the NAT node (100) receives an UL data packet (403) in which a source address identifier corresponds to a network address of a user equipment (10) and a destination address identifier corresponds to the replacement network address (200-i), it performs NAT of the UL data packet (403) in accordance with the mapping. This is accomplished at least by modifying the destination address identifier in the UL data packet (403) to correspond to the network address (200-e) of the server (200). The NAT node (100) then sends the modified UL data packet (405) toward the server (200).

Abstract: A policy controller (30) of a mobile network receives an authorization request (302) for a packet-based service from a node (80). In response to receiving the authorization request (302), the policy controller performs an authorization check (305) to determine an authorization status of the service and sends an authorization response (306) to the node (80). The authorization response (306) indicates the authorization status of the service. In response to the same authorization request (302), the policy controller (30) performs at least one further authorization check to redetermine the authorization status of the service. If the further authorization check indicates that the authorization status of the service has changed, the policy controller (30) sends a status change message (311) to the node. The status change message (311) indicates to the node (80) that the authorization status of the service has changed.
