Abstract
A technique is used in an infrastructure (,) of a two-way radio synchronous communication system (,) to efficiently acquire a predetermined type of information from a selective call device (,). The technique includes receiving an inquiry (,), generating a response schedule, generating a response command message (,), transmitting the response command message, receiving a demand response (,), and accepting the demand response as an acknowledgment to the response command message. The inquiry includes a device latency needed for the selective call device to generate the predetermined type of information and includes a response length. The response schedule is determined from the device latency and the response length. The response command message includes a special command and the response schedule. The demand response includes the predetermined type of information, and is transmitted in accordance with the response schedule. The demand response is accepted as an acknowledgment to the response command message.
