Abstract

The invention provides a VoWLAN system based on a 1X EvDO-WiFi wireless router, which comprises a VoWLAN terminal, a WiFi wireless router based on 1X EvDO and a SIP server; the VoWLAN terminal is connected to a local area network of the 1X EvDO-WiFi wireless router which is connected to the Internet through CDMA network; any VoWLAN terminal can initiate calling and establish a SIP channel with the SIP server. With the adoption of the 1X EvDO-WiFi router, the VoWLAN system based on the 1X EvDO-WiFi wireless router of the invention greatly promotes and expands property and application scope of the wireless local area network, and provides convenience for a rapid deployment of wireless VoIP voice call (VoWLAN). Under a condition that a mobile network can be accessed, any IP telephone terminal (VoWLAN terminal) with WiFi property can be connected to the Internet at any place and realizes VoWLAN communication in an access manner with the wireless router.

Description

technical field [0001] The invention relates to the field of wireless VoIP communication, in particular to a VoWLAN system based on a 1X EvDO-WiFi wireless router. Background technique [0002] Existing wireless routers generally use CDMA 1X to wirelessly access the Internet, and connect terminals with WiFi wireless LAN technology, so that users can access the Internet wirelessly in any place covered by CDMA signals. [0003] Using wireless routers, users can access the Internet in remote locations or areas where wiring is inconvenient to achieve data communication. [0004] Existing wireless routers use CDMA 1X wireless communication technology, which has limitations in communication rate. [0005] The existing VoWLAN system mainly uses a WLAN AP (wireless access point) to directly access the Internet to realize wireless VoIP voice communication. But in remote locations or other occasions without Internet access, the existing VoWLAN system is difficult to deploy and imple...
