The period of time over which the event or activity actually occurs.

Offline charging method and device

The invention provides an offline charging method and device. The offline charging method comprises the following steps that after a service data bearer is established, when a user plane subsystem (UPPS) receives a service data starting instruction message triggered by a charging trigger functional (CTF) entity, local absolute time is acquired to obtain the opening time of a first generated call ticket, and the opening time is sent to a charging data functional (CDF) entity; when a time threshold value is reached or a flow threshold value is reached or the service data bearer is updated or the service data bearer is deleted, the UPPS acquires a local absolute moment as a current moment and transmits the current moment to the CDF entity; the CDF entity conducts call ticket calculation on service data according to the received message. The embodiment of the invention further provides an offline charging device on the other hand. According to the technical scheme, the filling-in of call ticket time information better conforms to actual service transmission time, and the problem that the time is inconsistent with actual duration as a result of the generated call ticket is avoided. Besides, time delay in message processing can be effectively shortened, and call ticket duration deviation is reduced.

Charging pile system capable of counting actual duration of occupying powered parking space of electric vehicle

The invention discloses a charging pile system capable of counting actual duration of occupying a powered parking space of an electric vehicle. The charging pile system comprises a parking space, a fixed obstacle in the lateral direction of the parking space, a charging pile, a detecting device used for detecting a use condition of the parking space, a card swiping device used for supporting a user to swipe a card to pay, an electric parking space lock capable of preventing a car from entering and exiting the parking space, and a control device. The charging pile system is characterized in that the detecting device, the card swiping device and the electric parking space lock are connected with a control device in a wired or wireless mode; if the control device detects that the parking space is changed into a used state from an unused state through the detecting device, and the parking space is found to be continuously in the used state for duration extending duration t predefined in the system, a moment T of starting to the use the parking space of the user is recorded, and the electric parking space lock is noticed to lock; and if the control device receives a signal that the user swipes the card to pay through the card swiping device, the electric parking space lock is noticed to unlock, and duration of using the parking space this time of the user is obtained by calculating according to current time and the T.
