Abstract

The invention relates to the technical field of wireless communication and discloses a double radio frequency scheduling method for quick switching. The method comprises: calculating and collecting measurement data of a plurality intelligent triggers according to metric values of different layers of wireless network access link of a mobile terminal, and acquiring a scanning decision limit by using a multi-condition decision unification algorithm; and when the intelligent triggers are normal, allowing the mobile terminal to execute intelligent trigger decision scanning according to the scanning decision limit, or when the intelligent triggers are abnormal, allowing the mobile terminal to execute periodical scanning. When the double radio frequency scheduling method for quick switching, disclosed by the invention, is used, the alternate activating and deactivating double radio frequency scheduling interfaces are used to execute active scanning. When the method is used in the mobile terminal, unnecessary energy consumption is avoided and the performance of the quick switching is not lowered.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, more specifically, to a scheduling method of dual radio frequency interfaces used for fast switching in a wireless network. Background technique [0002] With the development of wireless communication technology, the application based on wireless network has grown rapidly, and a large number of different types of mobile terminals have emerged, such as portable notebook computers, smart phones and personal digital assistants (PDA). Due to the mobility of mobile terminals, it is necessary to Frequently change network attachment points such as base stations or wireless network access points to enhance the application performance of wireless networks. [0003] Currently, the dual radio interface scheme has been adopted as a promising solution in academic and industrial applications to support fast handover processing in homogeneous wireless networks or heterogeneous wireless ne...
