Power optimized request response communication protocol with timer mechanism to enforce client to generate request
First Claim
1. An asymmetric two-way request-response communication method providing communication between a client transceiver servicing a user/application and a server transceiver while providing power management and conservation of power at the client transceiver, comprising:
- maintaining the client transceiver in a power-off state until the client transceiver initiates a client communication with the server and enters a power-on state;
the client transceiver initiates a client communication with the server transceiver and requests information from the server transceiver;
the server transceiver transmits a server communication with the requested information to the client transceiver;
the client transceiver receives the server communication and then returns to a power-off state;
the server transceiver stays in a listening mode and waits for a client communication, and the server transceiver does not transmit unsolicited server communications to the client transceiver.

Abstract
In order to support connectivity requirements for today'"'"'s pervasive devices, the present invention provides an asymmetric two-way request-response communication protocol in which the end user or application is an active participant in the power management scheme. No power is consumed until a user-initiated client request is made. At that time, the client activates its transceiver and attempts to connect to the server; if it succeeds, it requests information, receives its response, and disconnects again, totally shutting down the transceiver. The server'"'"'s transceiver always stays in a listening mode and waits for a client request. The protocol does not provide a direct method for the server to send unsolicited messages to the client.
