Abstract

The invention provides a disaster recovery method based on wireless packet gateways. The method specifically comprises: choosing a standby wireless packet gateway of a master wireless packet gateway according to acquired information of the standby wireless packet gateway when the master wireless packet gateway is unavailable, wherein the standby wireless packet gateway and the master wireless packet gateway have a section of the same address pool; and establishing path connection with the standby wireless packet gateway. The invention also provides a packet data network gateway device and a disaster recovery system based on the wireless packet gateways. Through the method provided by the embodiment of the invention, the invention gives a specific proposal for realizing disaster recovery based on the wireless packet gateways, thereby reducing network risk and improving service quality.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a disaster recovery method, device and system based on a wireless packet gateway. Background technique [0002] In order to enhance the competitiveness of future networks, 3GPP (third Generation Partnership Project, third generation cooperation project) is studying a brand new evolved network. In order to reduce service interruption caused by natural disasters and provide users with high-quality and stable services, the new evolved network proposes the concept of PGW POOL (Packet Data Network Gateway Pool, packet data network gateway resource pool). [0003] In the process of realizing the present invention, the inventor found that at least the following problems existed in the prior art: [0004] The 3GPP agreement does not provide a specific implementation method of the PGW POOL, and furthermore, does not provide a specific implementation method for realizing disa...
