Abstract: An optical amplifier includes at least two stages of optical amplifier systems, an optical switch, a dynamic gain equalizer (DGE), and a control circuit. An input end of the optical switch is separately coupled to an output end of a first-stage optical amplifier system and an output end of a second-stage optical amplifier system, and an output end of the optical switch is separately coupled to an input end of the second-stage optical amplifier system and an input end of the DGE. The optical switch is configured to set at least two gain modes of the optical amplifier. The control circuit is configured to adjust an attenuation spectrum of the DGE based on the at least two gain modes set by the optical switch. The DGE is configured to perform, based on an adjusted attenuation spectrum, power attenuation processing on signals of different wavelengths in a received optical signal.

Abstract: A network function information management method, where the method includes: obtaining, by a management network element, identification information of a network repository function (NRF) instance, where the NRF instance stores information about a network function (NF) instance, and the identification information is used to indicate the NRF instance associated with the NF instance; and sending, by the management network element, a first message to the NF instance or a management unit of the NF instance, where the first message includes the identification information of the NRF instance; or establishing, by the management network element, an association relationship between the NF instance and the NRF instance based on the identification information of the NRF instance. The method helps the NF instance register with the NRF instance, update the information about the NF instance to the NRF instance, or query information about another NF instance from the NRF instance.

Abstract: This application provides a message parsing method, a data transmit end, a data receive end, and a system, and pertains to the field of network technologies. The method includes: when creating an XML message, the data transmit end may add a target identifier to the XML message to indicate an independent message block in the XML message, where the independent message block is an independent context-free message block, and then may transmit the XML message to the data receive end; and in a process of receiving the XML message, if it is detected that the target identifier exists in the XML message, the data receive end may capture, from the XML message, the independent message block corresponding to the target identifier, and then parse the captured independent message block.

Abstract: Embodiments of the present invention provide a method and device for handling a cell outage. The method for handling a cell outage includes: receiving, by a first base station, an energy saving activation message sent by a second base station when a cell outage happens to a second cell, where the energy saving activation message is used to disable the energy saving function; transferring, by the first base station, the first cell from the energy saving state to the normal state according to the energy saving activation message, or keeping a third cell in the normal state until learning that the cell outage of the second cell is solved. This method prevents a coverage blind area in the network when a cell outage happens to a second cell that covers the area of a first cell which is in the energy saving state.
