Alarm and messaging communications system having wireless network gateway
First Claim
1. A wireless network gateway in an alarm system, said alarm system including a wireless network providing wireless communication for a plurality of wireless communications devices and including a system server providing alarm services, the wireless network gateway comprising:
- a translation module for translating an alarm message transmitted from a wireless communications device of said plurality of wireless communications devices using a wireless network transmission protocol into an alarm message that is transmitted to the system server using a second transmission protocol having a different transmission rate, and for translating an alarm message received from the system server using the second transmission protocol into an alarm message for transmission to other wireless communications devices using the wireless network transmission protocol;
a proxy module for maintaining registration information for the wireless communications devices and maintaining an availability status of each registered wireless communications device, wherein when the system server initiates communication with a wireless communications device the system server contacts the proxy module and checks whether the status of the wireless communications device is available, if it is determined that the status of the wireless communications device is unavailable, the proxy module responds using the second transmission protocol with a message informing the system server that the wireless communications device is unavailable.

Abstract
A wireless network gateway in an alarm system is disclosed. The alarm system includes a wireless network providing wireless communication for a plurality of wireless communications devices and includes a system server providing Web, alarm and messaging services. A wireless network gateway of the invention may include a translation module that can translate messages from UDP format to TCP format, or from TCP format to UDP format. A proxy module of the wireless network gateway can maintain registration information for the wireless communications devices and maintain an availability status of each registered wireless communications device. The proxy module can check the availability status of wireless communication devices when the system server initiates communication such that, if it is determined that the status of the wireless communications device is unavailable, the proxy module responds using UDP/IP with a message informing the system server that the wireless communications device is unavailable.

2. A method for sending a message to wireless devices through a wireless network gateway in an alarm/messaging system, the wireless network gateway having a translation module and a proxy module, the method comprising the steps of:
-
generating a message;
transmitting the message to a system server of the alarm/messaging system;
producing addressed messages from the transmitted message, the addressed messages including the addresses of said wireless devices;
determining a status of each of the addressed wireless devices, as either available or unavailable, wherein if the status of an addressed wireless device is unavailable, the proxy module sends a message to the system server indicating that the addressed wireless device is unavailable; and
sending messages to available addressed wireless devices. - View Dependent Claims (3, 4, 5, 6, 7)
