Method and system for providing service to customer's terminal in wireless personal area network

Abstract

The invention discloses a method for providing service for a subscriber terminal in a wireless personal area network and a shared secret key and an identifier of the subscriber terminal are stored in a safety entity and the subscriber terminal. The method of the invention comprises the steps that: after a service request is released by the subscriber terminal, the safety entity receives private information from the subscriber terminal and the private information is encrypted by the subscriber terminal according to the shared secret key; the safety entity then decrypts the private information according to the stored shared secret key and the identifier of the subscriber terminal; when the safety entity confirms that the subscriber terminal meets the safety requirement according to the private information after the decryption, the service requested by the subscriber terminal is allowed to be provided. The invention also discloses a system for providing service for the subscriber terminal in the wireless personal area network and the safety entity. In the invention, after being intercepted, since the private information is encrypted by the secret key provided by a telecommunications network, the private information is difficult to be decrypted, thus the safety for providing service for the subscriber terminal in the wireless personal area network is strengthened.

Description

technical field [0001] The invention relates to the technical field of short-distance wireless communication, in particular to a method and system for providing services for user terminals in a wireless personal area network. Background technique [0002] Short-distance wireless communication technology is a large category of communication technologies. Short-distance is compared to technologies with longer communication distances such as cellular wireless communication and WIMAX (Worldwide Interoperability for Microwave Access). No more than a few hundred meters, including infrared, Bluetooth, UWB (ultra wideband, ultra-wideband technology), ZigBee (Zigbee, a low-speed short-distance wireless communication technology) and other technologies. The initial purpose of people developing short-distance wireless communication technology is to replace wired cables. For example, Bluetooth headsets can be wirelessly connected to mobile phones, which is convenient for users. [0003]...
