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： A backhaul domain of the communication network is determined 400, and a request for a synchronization reference is received 402 from the first access node, the request comprising, ID:s of the first and second access nodes. For each one of the first and second access nodes, a first and a second combination are determined 404 of a first and a second respective synchronization reference and related synchronization paths extending between synchronization reference nodes of the synchronization references and the access nodes. For each one of the first and second access nodes, the first or the second combination of synchronization reference and related synchronization path is selected 406 based on synchronization requirements for the first and second access nodes, and the first path or the second path is requested to be set-up 408 according to the selected 406 combination.By providing functionality which works on the top of existing control of radio and transport domains, appropriate synchronization references may be determined with a limited amount of information exchanged between the respective domains.

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： Method and communication network node for enabling a radio base station to adjust a Radio Access Network, RAN, capability within a RAN, such as handover or scheduling, dependent on a data transport characteristics of a backhaul network, such as data transfer rate, network delay and bandwidth. The RAN and the backhaul network are parts of a telecommunication network, and the first communication network node is arranged in the telecommunication network to communicate data between the RAN and a core network node in the telecommunication network.By acquiring knowledge of variations of transport characteristics in backhaul networks, RAN capabilities may be adjusted, e.g. by performing handover of UEs to other radio base stations which have better backhaul transport characteristics. Thereby, user experience for the users of the UE may be increased. In addition, an operator of the communication network may make better use of installed transport capacity.
