Wireless mobile device network application proxy with exchange sequence generator
Systems and methods disclosed herein receive a network application proxy (NAP)-extended API function call issued by a networking-aware host application. The NAP-extended API function call provides parameter values associated with a host off-loadable packet exchange sequence. Using the parameter values, a NAP module intercepts and responds to one or more incoming network packets associated with the host off-loadable packet exchange sequence while the host processor is in a sleep mode state or is transitioning between sleep mode states.
1. A wireless mobile device comprising: A. host processor circuitry including operating system circuitry; B. an application processing circuit module coupled with the host processor circuitry; C. network application circuit modules coupled with the application processing circuit module; D. a wrapper circuit module coupled with the application processing circuit module; E. host network stack circuitry coupled with the wrapper circuit module and the application processing circuit module; F. a physical link circuit module having a receive output and a transmit input; and G. a network application proxy circuit module including: i. a receive circuit module having a receive input coupled with the receive output, a first output coupled with the host network stack circuitry, and a second output; ii. a transmit circuit module having a first input coupled with the host network stack circuitry, a second input, and a transmit output coupled with the transmit input; and iii. exchange sequence generator circuitry separate from the host processor circuitry and having a receive input coupled with the second output, a transmit output coupled with the second input, and being coupled with the wrapper circuit module.
