The program Solidification of handheld terminal is preserved in FLASH121, after powering on, system is responsible for program is copied in the RAM123 from FLASH121 by boot (Bootloader), embedded OS brings into operation in RAM123 subsequently, is controlling the work of whole handheld terminal.CPU122 is the main control unit of whole system, and it carries out data interaction by address date/bus and FLASH121 and RAM123, is keeping the operation of software, thereby is controlling whole system.CPU122 also carries out wireless interaction by pci bus control WLAN module 11 with the wireless base station, and data are received and dispatched and handled.

As shown in Figure 2, a kind of wireless base station comprises WLAN module 21, control module 22, network switch module 24 and telephone wire interconnecting module 25.Described control module 22 comprises CPU222, power down volatile memory RAM223 and power down nonvolatile storage FLASH221.Described network switch module 24 comprises Network Interface Module 241 and RJ45 interface, and described RJ45 interface is the netting twine interface.Described telephone wire interconnecting module 25 comprises telephone line interface module 251 and RJ11 interface, and described telephone line interface module 251 is the DAA interface module, and described RJ11 interface is a telephony interface.Described WLAN module is supported IEEE 802.11a/b/g, is used to handle and change the wireless data packet of WLAN.Wireless base station of the present invention is connected with handheld terminal by WiFi, keeps being connected with Internet by netting twine simultaneously, keeps being connected with PSTN by telephone wire.

Described Network Interface Module 241 is by Media Independent Interface (Media IndependentInterface, abbreviation MII) bus links to each other with CPU222, described RJ45 interface one end links to each other with Network Interface Module, the other end links to each other with the network (ADSL/Cable Modem) that operator is provided, thereby is connected to Internet.Described telephone line interface module 25 links to each other with CPU222 by Serial Peripheral Interface (SPI) (SerialPeripheral Interface is called for short SPI) bus, and described RJ11 interface one end links to each other with DAA interface module 251, and the other end links to each other with PSTN.Described CPU222 links to each other with described FLASH221, RAM223 respectively by address date/bus, described CPU222 also links to each other with an end of WLAN module 21 by pci bus, WLAN module 21 other ends are provided with a WLAN antenna, and the WLAN module 21 of described wireless base station can receive the wireless data packet that the WLAN module of handheld terminal is sent by WLAN (wireless local area network).

The program Solidification of wireless base station is preserved in FLASH221, after powering on, system is responsible for program is copied in the RAM223 from FLASH221 by boot (Bootloader), embedded OS brings into operation in RAM221 subsequently, is controlling the work of whole wireless base station.CPU222 is the main control unit of whole system, carries out data interaction by address date/bus and FLASH221 and RAM223, is keeping the operation of software, thereby is controlling whole system; CPU222 also links to each other with WLAN module 21 by pci bus, and one carries out wireless interaction with handheld terminal, and data are received and dispatched and handled, and simultaneously, can be used as wireless router, supports the online computing in the WLAN (wireless local area network); CPU222 also controls DAA interface module 251 by spi bus, thereby is connected with PSTN; CPU222 also passes through MII bus Control Network interface module 241, thereby is connected with Internet.

As shown in Figure 3, the course of work of handheld terminal of the present invention and wireless base station is as follows: based on the WiFi network, the user calls by handheld terminal earlier, selects the phone type that will dial again.Undertaken alternately by specialized protocol between handheld terminal and the wireless base station, related command is resolved after receiving the data that handheld terminal sends in the wireless base station, judges the phone type that the user will dial.When the wireless base station is judged the user-selected phone type of dialing and is the networking telephone, undertaken alternately by specialized protocol between handheld terminal and the wireless base station, the CPU of wireless base station receives related data; The CPU of wireless base station is connected to server on the Internet by the network switch module, carries out calling network; When the user-selected phone type of dialing is black phone; Undertaken alternately by specialized protocol between handheld terminal and the wireless base station, the CPU of wireless base station receives related data; The CPU of wireless base station is connected with PSTN by the telephone wire interconnecting module, carries out traditional telephony call.The wireless base station turns back to handheld terminal with the result at last, and access success then continues, and call failure is then informed failure.

Simultaneously, handheld terminal of the present invention is also supported standard agreement, that is to say to use as common WiFi handset.Handheld terminal of the present invention does not so need supporting wireless base station of the present invention, as long as in existing WLAN (wireless local area network) scope, all can be connected with common WiFi wireless router, dials the voip network phone.

Same handheld terminal of the present invention can switch between " agreement " identical different radio base station, realizes wireless function.For example, the user can stay at home and office in use same handheld terminal, simultaneously,, can transfer to office to the phone of family by network by software setting, accomplish the one-to-one relationship of number and terminal.The medium access control of handheld terminal (Media AccessControl, abbreviation MAC) address is unique, it can be used as unique ID of sign handheld terminal, the user stays at home and office has all disposed the wireless base station, after arriving office, the user is provided with calling transfer by handheld terminal, the MAC Address of handheld terminal and the public network IP of office's local area network (LAN) can be registered on the server of Internet.

When the landline telephone of family has calling to enter, the wireless base station of family finds the local MAC Address that does not have the corresponding handheld terminal of this user in the tabulation that connects, so call request is submitted to the server of Internet, whois lookup is to the IP of the hand-held present residing local area network (LAN) of terminal, send calling immediately, after the user answer, get through voice and connect, the user can be connected to the wireless base station of family by Internet subsequently, and the calling of the landline telephone of family is replied.

Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
