System and method for supporting inter-network dispatch calls
First Claim
Patent Images
1. A method for a server supporting an inter-network dispatch call, the method comprising the acts of:
- receiving bearer packets from a second communications network;
starting a first timer when bearer packets are not received;
starting a second timer when the first timer has expired; and
transmitting bearer packets to a first communication network for a duration of the second timer,wherein a duration of the first timer is less than a time-out value of a call in the first communication network,wherein the inter-network dispatch call is between a communication station in the first communication network and a communication station in the second communication network,wherein the second communication network does not employ a call time-out value.

Abstract
Systems and methods for communications between networks that support dispatch communication services are provided. A server is coupled to at least two networks that provide dispatch communications, one of which employs an inactivity timer. When the server determines that the inactivity timer for a dispatch call is about to expire due to, for example, no bearer packets being transmitted, the server will request the floor of the call. The server will then transmit bearer packets for a predetermined amount of time, and then release the floor.

6. A server, comprising:
-
a first interface coupled to a first dispatch communication network; a second interface coupled to a second dispatch communication network, the server receiving bearer packets from the second dispatch communication network via the second interface; and a processor coupled to the first and second interfaces, the processor comprising logic that determines whether a bearer packet is received; silence timer logic that starts a first timer when bearer packets are not received; floor timer logic that starts a second timer when the first timer has expired; and bearer packet transmission logic that transmits bearer packets to the first communication network for a duration of the second timer, wherein a duration of the first timer is less than a time-out value of a call in the first communication network, wherein the second communication network does not employ a call time-out value. - View Dependent Claims (7, 8, 9, 10, 11)
