Abstract

The invention discloses a wireless terminal and a method for making the wireless terminal switch between two kinds of wireless networks. The method comprises the following steps: maintaining a point-to-point protocol session which is via a first link between the wireless terminal and a first wireless network; establishing a second link between the wireless terminal and a second wireless network, after that, intercepting the point-to-point protocol session from a virtual network adapter in an operation system of the wireless terminal, and switching the point-to-point protocol session to the established second link. After the second link is established, the point-to-point protocol session which is intercepted from the virtual network adapter in the operation system of the wireless terminal is switched to the second link so that the point-to-point protocol session between the wireless terminal and the network is not interrupted and continuous transmission of service data is realized.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a wireless terminal and a method for switching the wireless terminal between two wireless networks. Background technique [0002] With the development of mobile communication technologies, for example, Code Division Multiple Access (CDMA) 2000 technology, including CDMA20001X and CDMA20001XEVDO (Evolution Data Only), has become one of the most widely used mobile communication technologies at present. Among them, CDMA20001X technology, as the first stage of CDMA2000, can carry both voice services and packet data, realizing not only providing users with traditional voice services, but also providing users with data services in the end-to-end packet transmission mode, providing Internet access enter. CDMA20001XEVDO technology is an enhanced method for CDMA20001X in providing data services. It is a CDMA2000 control interface technology optimized for high-speed packet data transmi...
