Abstract

The invention provides a double-mode / multimode portable device and its intelligent switching method, and the device comprises: voice collecting section, voice playing section, processing unit and the first and second subsystems, mutually independent, where the first subsystem comprises VoW control module, VoW hardware driving module and VoW protocol entity as well as physical bearing entity layer module, able to make an IP telephone call based on WWAN network, and thus implementing a double-mode / multimode portable device with low communication fee and good mobility. And the method includes: using the first subsystem to communicate; as detecting the signal of the first subsystem is lower than the preset threshold or meets the preset switching condition, preparing for switching to the second subsystem; removing the signal of the first subsystem and using the second subsystem to communicate, thus completing the intelligent switching of the voice data in the two modes and implementing the method.

Description

【Technical field】 [0001] The invention relates to a dual-mode / multi-mode portable device and an intelligent switching method thereof, in particular to a dual-mode / multi-mode portable device based on IP network voice transmission technology and an intelligent switching method thereof. 【Background technique】 [0002] At present, Voice over Internet Protocol (VoIP for short) technology based on IP network is more and more favored by telecom operators and enterprise users due to its low price and convenient configuration. [0003] With the development of wireless local area network (Wireless Local Area Network, referred to as WLAN) technology, and with the growing number of wireless fidelity (wireless fidelity, that is, WiFi) networks in enterprises and homes, the mobility of VoIP technology has become a reality, and users can Access the WLAN through a high-speed network to make calls within the coverage of the WLAN. In this way, voice application based on wireless local area n...
