Problems solved by technology

Therefore, in order to solve the problem that when a wireless network phone uses a wireless local area network to make a call, it is easy to disconnect the communication session due to insufficient signal strength of the connection between the wireless local area network and the phone due to the mobile state of the phone user or the influence of obstacles. In order to solve the problem of wires, the present invention provides a method for dynamically controlling the transmission path of the data packet of the wireless network phone, so that when the wireless local area network connection signal is weakened, the GPRS network is used to transfer the IP data packet of the wireless network phone. to maintain the call

Embodiment Construction

[0033] Referring to FIG. 1 , it is a schematic structural diagram of a network telephone system according to an embodiment of the present invention. The wireless phone 100 includes two modules for communication: a wireless local area network (WLAN) module 102 and a GPRS module 104 . In this embodiment of the present invention, the wireless local area network module used is a Wi-Fi module, but the wireless local area network module of the present invention is not limited thereto, but can be other standards that meet IEEE802.11 series or IEEE802.16 series The wireless LAN module

[0034] The wireless LAN phone 100 can connect to the wireless local area network 106 by means of the WLAN module 102 , and the wireless LAN phone 100 can also connect to the GPRS network 108 through the GPRS module 104 . Both the WLAN 106 and the GPRS network 108 are connected to an Internet 110 . And a called party phone 120 can also be directly or indirectly connected to the Internet 110 . Therefo...

Abstract

The invention relates to a data pack transmission path control method, network phone system and wireless network phone. Wherein, said method comprises that first, building the first connection between wireless network phone and wireless local network; building the second connection between wireless network phone and general group wireless service; based on the signal strength of first connection received by wireless network phone, decides the path of several data packs exchanged in one conversation group built by wireless network phone and other network phones is the first or second connection. The invention can avoid off connection caused by weak signal.

Description

technical field [0001] The present invention relates to a wireless network phone, in particular to a wireless network phone supporting both the wireless local area network communication standard and the general packet radio service (General Packet Radio Service, GPRS) communication standard. Background technique [0002] The Wi-Fi communication standard is a general term for a group of wireless local area network (WLAN) communication standards, including standards such as 802.11a and 802.11b compatible with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 specification. Due to the prevalence of wireless networks, the Wi-Fi communication standard has been widely adopted by the industry. [0003] Due to the popularity of the Internet, many standards have been born to use the Internet to transmit voice data. General Internet protocol telephony (IP telephony) uses H.323, SIP, MGCP and other standards to transmit call control signals, and uses user datagram pr...
