Embodiment Construction

[0015] The content of the present invention will be explained through the following embodiments, and the description of the present invention is about a method and device for renewing keys and a wireless network system using the method and device. In the present invention, the key update time points are divided into real-time update time points and non-real-time update time points. The key update action at the non-real-time update time point will be delayed to the subsequent real-time update time point batch processing, so as to reduce the burden caused by the wireless network system 1 updating the key. Embodiments of the present invention are not limited to specific environments, applications, or implementations. Therefore, the descriptions of the following embodiments are for illustrative purposes only, rather than limiting the present invention.

[0016] The first embodiment of the present invention is a wireless network system 1, the schematic diagram of which is as follow...

Abstract

The invention discloses a key updating device and a key updating method, and a wireless network system comprising the key updating device. The method is suitable for a first base station which belongs to a wireless network system. The first base station has a first signal range and uses a first key. The method comprises the following steps: judging that a mobile device moves to the first signal range from a second signal range of a second base station; judging that the logon time of the mobile device to the wireless network is later than the updating time of the first key; updating the first key; and transmitting the first key to the mobile device.

Description

technical field [0001] The present invention relates to a key updating device and method and a wireless network system including the key updating device; more specifically, the present invention relates to a key updating device and method that reduces the number of real-time key updating and includes The wireless network system of the key updating device. Background technique [0002] In recent years, with the advancement of the times, people spend more and more time communicating with mobile devices. Most of the current mobile devices have their own wireless network systems, such as Global System for Mobile Communications (GSM), Wideband Code Division Multiple Access (WCDMA), Worldwide Interoperability for Microwave Access ; WiMax) and so on. These wireless network systems all provide a multicast function to meet individual requirements of some specific users. When sending messages via multicast, a key must be used. All mobile devices in this group can use this key to d...
