Embodiment Construction

[0021] figure 1 is a block diagram of an exemplary system 10 in which a secure VPN gateway 12 provides secure access to protected resources 14 of an enterprise network 16 . That is, secure VPN gateway 12 enables secure and controlled access to resources provided by enterprise network 16 . For example, endpoint computing devices (“ECDs”) 18A-18M and cellular mobile devices 19A-19N remotely access enterprise network 16 via service provider network 20 and intermediate packet data network 21 , such as the Internet.

[0022] In one embodiment, secure VPN gateway 12 is a Secure Sockets Layer VPN (SSL VPN) device that provides VPN services to clients. Further details on SSL VPN equipment and operation can be found in "Juniper Networks Secure Access Administration Guide, Release 6.5," Juniper Networks, Inc., 2008, the entire contents of which are hereby incorporated by reference. Secure VPN gateway 12 may be a stand-alone device or may reside on one or more other devices, such as an...

Abstract

The invention relates to a VPN network client for mobile device having fast reconnect. The VPN network client establishes a secure VPN connection with a remote VPN security device. The VPN network client establishes a secure control channel with the secure VPN gateway and, upon a successful authentication, receives a session cookie with a unique identifier. In the event communication with the secure VPN gateway is subsequently temporarily lost, the VPN network client performs a fast reconnect without requiring re-authentication of the cellular mobile device by communicating the session cookie to the secure VPN gateway. Prior to performing the fast reconnect, the VPN network client identifies a set of transport mechanisms currently available to the cellular mobile device and, when only a cellular network is available and not a wireless packet-based connection, the VPN network client defers the fast reconnect until application-layer data is received from a user application and is ready to be sent to the remote VPN security device via the VPN connection.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application 61 / 398,758, filed June 30, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to cellular networks, and more particularly, to cellular-based network data services. Background technique [0004] Recently, the use of cellular mobile devices to access computer data networks has increased dramatically. These mobile devices, often referred to as "smart" phones, provide a platform for both cellular telephone calling and cellular-based access to computer data services. For example, a typical cellular radio access network is a collection of cells, each of which includes a base station capable of transmitting and relaying radio signals to users' mobile devices. A "cell" generally refers to an isolated area of ​​a cellular network that utilizes a particular frequency or range of ...
