Kommunikationssystem, förfarande för förlängning av passningstid och datorläsbart medium för detta

摘要

A communication system, a method for extending stand-by time, and a computer readable medium therefor are provided. The communication system includes a mobile communication apparatus and a core network. The method and the computer readable medium therefor perform the following steps. When the mobile communication apparatus is in a low battery situation or required to enter a power saving mode by a user, it sends a signal to the core network to request to enter the power saving mode. After receiving the signal, the core network reduces a data quantity transmitted to the mobile communication apparatus, and thereby the purpose of extending stand-by time is achieved.
