    摘要： A method (100) is disclosed, the method being performed in a network controller of a Mobile Transport Network. The Mobile Transport Network comprises communication links interconnecting network entities of a cellular Radio Access Network (RAN) and a core network. The method comprises receiving, from a network entity in the core network, an indication of traffic load within the RAN or between the RAN and the core network (102). Also disclosed is a method (200), performed in a network entity of a core network, the core network being connected to a cellular RAN by a Mobile Transport Network. The Mobile Transport Network comprises communication links interconnecting network entities of the core network and the RAN. The method (200) comprises sending to a network controller of the Mobile Transport Network an indication of traffic load within the RAN or between the RAN and the core network (202). Also disclosed are a network controller (300, 500), a core network entity (400, 600) and a computer program product configured to carry out methods in a network controller a core network entity.

    摘要： An ONT and a method therein for maintenance and administration of the ONT are provided. The ONT is comprised in an Optical Distribution Network, ODN. The method comprises connecting 210 an OLT in the ODN to a maintenance unit comprised in the ONT when a first signal is received from the OLT instructing the ONT to enter a maintenance mode. The method comprises updating 220 existing maintenance and administration information in the maintenance unit, the maintenance and administration information relating to the operation of the ONT when receiving new maintenance and administration information from the OLT. The method comprises connecting 230 the OLT to a host which host is connected to the ONT when receiving, from the OLT, a second signal instructing the ONT to enter an operation mode, or after a predetermined period of time; and operating 240 the ONT in accordance with the updated maintenance and administration information in the maintenance unit.

    摘要： Methods and apparatus for a network element or server end station to determine an estimated physical location of a fault in a communications link utilized by two network elements. In an embodiment, the first and second network elements generate link failure indications including time values representing when the respective network element detected the fault. In other embodiments, the link failure indications include time values transmitted over the communications link between the first and second network elements. A time distance between these time values is calculated, which is used to calculate the estimated physical location of the fault. In some embodiments, the link failure indications include sequence numbers transmitted or about to be transmitted over the communications link between the network elements. Sequence distances are calculated between the sequence numbers, and are used to calculate the estimated physical location of the fault.
