System and method of mobile terminal for selecting optimal communication network

Abstract

The invention relates to a system and a method of a mobile terminal for selecting an optimal communication network. The system comprises a network availability detection module, a network quality detection module, a network quality test server, a network selection rule configuration module, a service perceiving module, a network selecting module and a network switching module, wherein the network availability detection module is used for detecting the network availability and connectivity of a communication network involving the mobile terminal in real time; the network quality detection module and the network quality test server are used for detecting the communication quality of an available and connected communication network; the network selection rule configuration module is used for configuring the network selection priority according to user demands; the service perceiving module is used for detecting the service currently used by the mobile terminal in real time; the network selecting module is used for selecting an optimal communication network according to the detection result of the network communication quality, the configuration result of the network selection priority and the service currently used by the mobile terminal; and the network switching module is used for switching the communication network currently used by the mobile terminal into the optimal communication network. According to the system and the method of the mobile terminal for selecting the optimal communication network, the demands on network quality, use expense and service requirements are comprehensively considered and users can make full use of the network and obtain the maximum profit on the premise of guaranteeing the communication quality.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a system and method for a mobile terminal to intelligently select an optimal communication network. Background technique [0002] Converged communication, also known as unified communication, uses a new communication mode that integrates computer technology and traditional communication technology to provide various communications including telephone, fax, file transfer, conference call, video, collaboration, instant messaging, email, and short message. means. Converged communication is no longer limited to telephones, but extends to PCs, PDAs, telephones, smart phones, H323 / SIP terminals and other devices. However, converged communication cannot provide the promised quality of service (QoS) guarantee like traditional telephones at present. Since converged communication is based on IP switching technology, media streams are transmitted in the form of data packets, which can...
