Abstract
An intersystem communication path (20, 67) can be established on an as needed basis. Already established paths are fully utilized before new paths are established. Already established paths can be automatically disconnected when no longer needed, or when existing calls can be merged on to fewer lines. Dial up lines can be mixed with dedicated lines. If desired, excess capacity can be guaranteed to accommodate high traffic conditions and/or other conditions that precipitate a likely need for communication services between systems.
Claims15
A method of conducting a voice communication between a first communication unit serviced by a first radio frequency communication system and a second communication system serviced by a second radio frequency communication system, comprising the steps of:
- A) determining whether a first multi-channel communication path exists between the first and second radio frequency communication systems;
- B) when the first multi-channel communication path so exists, determining whether the first multi-channel communication path has at least one channel to support the voice communication;
- C) when the first communication path has at least one channel, initially establishing the voice communication using only one channel of the first multi-channel communication path;
- D) when either the first multi-channel communication path does not exist or the first multi-channel communication path has insufficient capacity;
- i) automatically establishing a new multi-channel communication path to support the voice communication;
- ii) initially establishing the voice communication using only one channel of the new multi-channel communication path.
a method comprising the steps of:
- A) determining that, although there is no present necessity to support a voice communication between a communication unit in a first radio frequency communication system and a communication unit in a second radio frequency communication system, it will likely be necessary to soon support a voice communication between a communication unit in a first radio frequency communication system and a communication unit in a second radio frequency communication system;
- B) determining whether a first communication path exists between the first and second radio frequency communication systems;
- C) when the first communication path so exists, determining whether the first communication path has sufficient capacity to support the voice communication, should it be necessary to soon support the voice communication.
A method of conducting a voice communication between a first communication unit serviced by a first RF communication system and a second communication unit serviced by a second RF communication system, which first and second RF communication systems are coupled by a dedicated communication path, comprising the steps of:
- A) determining whether the dedicated communication path will initially support the voice communication;
- B) when the dedicated communication path will support the voice communication, using the dedicated communication path to initially support the voice communication;
- C) when the dedicated communication path will not initially support the voice communication:
- i) determining whether a non-dedicated communication path exists between the first and second RF communication systems;
- ii) when the non-dedicated communication path so exists, determining whether the non-dedicated communication path has sufficient capacity to initially support the voice communication;
- iii) when the non-dedicated communication path has sufficient capacity, initially establishing the voice communication using the non-dedicated communication path.
