A push-to-talk (PTT) communication system provides a destination subscriber (called party) with a flexible incoming call management feature in which an initial voice message associated with the initial PTT incoming call to the called party is temporarily stored at the communication application server and is not transmitted to the called party's mobile terminal. The called party is informed of an incoming call by an alert message from the communication application server causing the called party's mobile terminal to provide an alert. The called party may elect one of several options upon being alerted of an incoming call including transmitting a signal requesting the voice message be played.

Incoming call management in a push-to-talk communication system

In a telecommunications system (), a method and apparatus for buffering the initial speech of an initial speaker in a push-to-talk call is disclosed. The method includes the steps of determining at least one participant or group to call (), sending a call request to the at least one participant or group (), determining if the at least one participant or group is registered with the telecommunications system, notifying the initial speaker to begin speaking after determining at least one participant is registered with the telecommunications system but prior to connecting all called parties, receiving and digitizing voice packets from the initial speaker, storing the digitized data packets in a storage medium and transmitting the digitized voice packets when a predetermined packet transmission triggering event occurs. The apparatus for buffering the initial speech burst of an initial speaker in a call includes a first server () and a second server () communicatively connected to the first server. The second server is programmed to execute the steps of the method described above.

Method and apparatus for decreasing perceived push-to-talk call set-up time using a buffer for initial speech burst

Coupling together two or more communication systems that use different signaling protocols requires a protocol converter. A protocol converter is provided that includes interfaces to communications systems to be coupled together mimics the operation of the communications systems each interface is coupled to providing a seamless coupling between the systems.

Methods and apparatus for translating between telephone signaling protocols

A technique for updating the software in a remote computer (e.g., a base station, a spacecraft in space, an electronic postage meter in an office, a medical monitoring device in a patient's home, etc.) from a central control (e.g., a wireless switching center, the National Aeronautics and Space Administration's Houston Control, a postage meter facility, a medical equipment manufacturer's factory, etc.) is disclosed. An illustrative embodiment of the present invention comprises: checking the integrity of a first software application at a first location in a first memory that is pointed to by a first address in a pointer; copying the first software application from the first memory to the second memory and executing the first software application from the second memory, when the integrity of the first software application is nominal; transmitting a first message indicating that the integrity of the first software application is not nominal, when the integrity of the first software application is not nominal; and receiving a first command to store a second address in the pointer, in response to the first message.
