A method and apparatus for allocating an identifier to a terminal in a communications network. A core network controlling node, such as a Mobility Management Entity (MME) receives an International Mobile Subscriber Identity (IMSI) and an International Mobile Equipment Identity (IMEI) from the terminal. Subscription information is determined using both the IMSI and the IMEI. A temporary identifier that can be used to identify the terminal is then allocated to the subscription information.

In a hybrid construction machine, its display device displays, toward an operator, an artificial engine sound serving as load information according to a magnitude of a workload, instead of an engine sound. Furthermore, the display device issues an alarm sound to surrounding workers when performing an operation by only stored electrical power of an electrical energy storage device without using an engine. In this hybrid construction machine, in addition to the issuing of alarm from the display device during the operation without using the engine, the display device issues an advance notice sound for engine restart when at least one value out of the workload and a charge amount of the electrical energy storage device has become an advance notice set value close to a set value of engine restart.

The present invention relates to an information processing device and method, and specifically discloses an information processing method for performing processing on unit data in which one content is processed as one unit. In order to continuously reproduce and output content data, after the decryption/demodulation process of the current content data is terminated, the falsification checking process is started for the next content data reproduced after the current content data being reproduced. This eliminates the time interval when the decryption/demodulation process of the current content data and the falsification check process of the next content data are simultaneously performed, thus preventing an increase in processing load caused by the simultaneous execution of the falsification check process and the decryption/demodulation process.
