Embodiment Construction

[0029] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, a handheld terminal includes a control module 12 and a WLAN module 11 . The control module 12 includes a power-off nonvolatile memory FLASH121 , a power-off volatile memory RAM123 and a central processing unit CPU122 . The CPU 122 is respectively connected to the FLASH 121 and the RAM 123 through an address / data bus, and the CPU 122 is also connected to the WLAN module 11 through a Peripheral Component Interconnect (PCI for short) bus. WLAN module 11 supports IEEE 802.11a / b / g, one end of this module is connected with CPU122 through PCI bus, and the other end is provided with a WLAN antenna, and described WLAN module is responsible for processing and converting the wireless data packet of WLAN, and sends the wireless data packet to a wireless LAN. The wireless local area network is construct...

Abstract

The present invention discloses a handheld terminal, including interconnected control modules and WLAN modules, wherein the control modules transmit a corresponding order signal to the WLAN modules according to the call mode selected by a user; the WLAN modules send the received order signals to a wireless LAN; and the call model includes calling the network telephone and traditional telephone. Also disclosed is wireless base stations matching with the handset terminal. The wireless base station includes interconnected control modules and WLAN modules, and the network adapter module and telephone lines adapter module linked to the control modules. The control modules receive the order signals that the WLAN modules receives from the wireless LAN, and switches to the corresponding network adapter module in accordance with the order signal to connect the the control modules with the Internet, or switches to the telephone lines adapter module to connect the control modules with the PSTN. Using the present invention, users can freely choose to take the VoIP network calls or traditional phone calls.

Description

technical field [0001] The present invention relates to wireless technology, in particular to a hand-held terminal and its matching wireless base station. Background technique [0002] Voice over IP (VoIP for short) is a new technology that uses Internet technology or LAN IP technology to realize telephone communication. It compresses and packets the analog voice signal, and transmits the voice signal in the form of data packets in the IP network environment. The most basic function of VoIP is to provide low-cost voice and fax services based on the Internet (Internet). A WiFi mobile phone is a hand-held terminal device that has the characteristics of a portable mobile phone and can access the Internet through WiFi to make VoIP network calls. [0003] The cordless phone is also called a master phone. The master phone is connected to the Public Switched Telephone Network (PSTN) through a telephone line, that is, the PSTN telephone network. The slave phone can realize wireles...
