ALWAYS-ON VIRTUAL PRIVATE NETWORK ACCESS

摘要

An application processor is electrically and logically decoupled from a wireless data network module so that it may go to sleep independently. A security association may be established between the wireless data network module and a wireless data network. Then the application processor may be placed in a suspend state while maintaining the security association between the wireless data network module and the wireless data network. This allows email polling, for example, to occur without having to re-establish the security association by logging in again.
