Abstract

The embodiment of the invention discloses an IP address configuration method and device, relates to the technical field of mobile communication, and can solve the problem of IP address shortage when 4G technology is applied in a VPDN network. The method in the embodiment of the present invention includes: judging whether there is traffic; if not, switching the modem from the 4G system to the 3G system; sending a logout instruction to the operator network equipment, so that the operator network equipment receives the logout instruction Then initiate a logout request to the VPDN network device; release the allocated IP address of the VPDN network after successful logout. The present invention is applicable to the process of applying 4G technology in VPDN network.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an IP address allocation method and device. Background technique [0002] VPDN (Virtual Private Dial-up Networks, Virtual Private Dial-up Networks) can use mobile communication networks, combined with wireless network cards or wireless routers and other equipment, to meet the needs of wireless data transmission for internal office networks, production networks and other networks. Compared with traditional mobile communication technologies, 4G technology (The 4th Generation Mobile Communication, fourth-generation mobile communication technology) has the characteristics of high bandwidth and low delay, and is a new technology that can provide high-quality data transmission services for all IP. The application of 4G technology in the VPDN network can improve the performance of data communication services. [0003] In the prior art, in the process of implementing the ab...
