Nippon Telegraph and Telephone Corporation patent applications published on November 9th, 2023

Summary of the patent applications from Nippon Telegraph and Telephone Corporation on November 9th, 2023

Nippon Telegraph and Telephone Corporation has recently filed several patents related to communication systems and technologies. These patents cover a range of areas including positioning systems, transmission power control, optical communication systems, communication system management, anomaly detection, identifier changes, wireless communication systems, symbol determination, and multiplex transmission systems.

In the positioning system patent, the organization describes a system that estimates the position of a wireless terminal based on signals received by a wireless base station device. The system also takes into account the position of relay devices.

The transmission power control patent outlines a method for controlling the transmission powers of multiple base stations in a coverage area. The method involves adjusting the transmission power of each base station based on the percentage of its individual coverage area.

The optical communication system patent introduces a looped path configuration with active and standby trunk fibers. The system includes optical combining/splitting units, sensors, and transmitters to detect and notify abnormalities in the communication path.

The communication system patent describes a system with branching devices, acceptance judgement apparatuses, and processing devices. The acceptance judgement apparatuses determine whether to transfer received signals to connected processing devices based on previously received signals.

The anomaly detection device patent presents a device that uses a learning unit and an anomaly detection unit to detect anomalies in a communication apparatus. The device can trigger relearning based on differences between the current detection model and a second communication log.

The identifier change management apparatus patent introduces a distributed ledger system for managing identifier changes. The apparatus includes units for managing the ledger, inputting secret keys, issuing transactions, and changing identifiers.

The wireless communication system patent focuses on detecting objects within a communication area using reference signals and propagation state information exchanged between a base station device and a terminal device.

The symbol determination device patent describes a device that determines transmission symbols in a communication system based on estimated transfer functions and candidate symbol sequences.

The optical communication system patent presents a system that uses an optical fiber with multiple parallel cores to simplify and improve the efficiency of optical communication.

The multiplex transmission system patent introduces a system that can handle failures while minimizing resource wastage. The system includes multiplex transmission apparatuses, a resource pool, and a management control unit.
