CPC Code(s): H04B10/07955
Abstract: the invention presents an optical transmission system and control method aimed at minimizing gain variation across wavelengths. the system has end stations exchanging wdm signals over a fiber optic cable with repeater stations. the repeaters split the wdm signals into multiple subbands which are separately amplified by optical amplifiers dedicated to each subband frequency range. there is a first subband with relatively shorter wavelengths and a second subband with relatively longer wavelengths. a monitoring unit tracks the output power of the longest wavelength channel in the first subband and the shortest wavelength channel in the second subband received at one end station. a control unit sends signals to the transmitting end station to adjust the gains, working to minimize the difference in output power between those two monitored wavelength channels. this aims to reduce gain variation across the full range of wavelengths in the wdm optical transmission system.

Abstract: provided is an analysis device that is capable of easily detecting, by using only communication data, a change in another communicatively connected communication device, or a change in a configuration of a communication network that is connected to the other communication device. first communication feature information that has been generated based on communication data over a predetermined time period with another communication device that is connected to the communication network, and second communication feature information that has been generated based on new communication data over a predetermined time period with the other communication device that is connected to the communication network, are compared to determine the presence or absence of a similarity in the communication feature information. a determination result indicating the presence or absence of a change relating to the communication network is output based on the presence or absence of the similarity.

Abstract: a master node (mn) () sends a control message to a candidate secondary node (sn) (). the control message indicates that one or more candidate pscells are to be prepared by the candidate sn for a first conditional mobility with addition or change of a pscell for a ue (). in addition, the control message indicates that a mode of operation is recommended in which configurations of the one or more candidate pscells to be provided to the ue () for the first conditional mobility are reused by the ue () for a subsequent conditional pscell change after the first conditional mobility. this can help, for example, to implement a feature or mode of operation that enables a subsequent second conditional mobility without reconfiguration or reinitialization by the network after a first conditional mobility.

Abstract: there is a new market requirement that a network slice needs to be deployed in area that does not overlap with the already deployed tracking areas and/or has a limited lifetime. as the latest 3gpp specification cannot fulfil the new market requirement, 3gpp specifications need to be enhanced.
