摘要： Determining a time synchronization inaccuracy value between a first node and a second node. A PTP packet is received including Node IDs representing respective transport nodes along a first path, and from the second node Node IDs are obtained representing respective transport nodes along a second path. Furthermore, a first common node of the first path and the second path is determined. The time synchronization inaccuracy value between the first node and the second node is calculated. By including Node IDs in received PTP packets before forwarding them to a node, the node is enabled to determine a first common node. Thereby, the node may calculate relative time inaccuracy values with respect to the other access network nodes, which may be used to decrease inaccuracy time synchronization for co-ordination functions.

摘要： An identifier of a first location server is received together with information regarding which communication devices the first location server stores geographic location information for. A location request is received from an Operator Location Service (OLS) node for requesting the geographic location information of the communication device. The location request originates from an Over The Top (OTT) service providing node and comprises an identifier of the communication device. The first location server is determined by utilising the received identifier of the communication device and the received identifier of a first location server. The geographic location information of the communication device is obtained from the determined first location server by utilising the received identifier of the first location server. The retrieved geographic location information of the communication device is sent to the OLS node, which forwards the received geographic location information to the OTT service providing node.

摘要： A network node enables a wireless device to communicate with a local service device, such as a printer or a projector, of a Local Area Network (LAN) or Wireless Local Area Network (WLAN). The network node is connected both to a communication network and to the LAN or WLAN. The method includes identifying a multicast Domain Name System (mDNS) request, where the mDNS request is received from the wireless device, and assigning a LinkLocal (LL)-address for the wireless device. The method retrieves a local IP-address of an Authentication and Authorization Service (AA-S) having authorization information regarding a local service device, and authenticates, with the AA-S which type of services, that the wireless device is authorized to use. A local IP-address of the local service device is retrieved, and service data is conveyed between the wireless device and the local service device, by applying the LL-address of the local service device.

摘要： The present invention relates to a method and node arrangement for evaluating available conditions of a data path between a sending node and a destination node in a data communications network by means of an active measurement process comprising one or more measurement sessions. The data path and sending node comprises a sending node interface. The method involves performing a measurement session of said data path for determining a measurement result, and estimating one or more available conditions of a data path using the measurement result and one or more initial parameter values as input in a calculation algorithm. The method further comprises setting one initial parameter value for the calculation to a maximum bandwidth capacity based on the lowest bandwidth capacity value of the interfaces of both nodes sending said probe packet sequences during said measurement session.
