Abstract
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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
156 words
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.
Claim 2
Independent Claim
156 words
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.
Claim 3
Dependent Claim
30 words
The method of claim 1, wherein step C further includes the step of: C1) compressing the voice communication prior to using the one channel of the first multi-channel communication path.
Claim 4
Dependent Claim
35 words
The method of claim 1, and further including the step of: C1) using the first multi-channel communication path to also support exchange of system control information between the first and second radio frequency communication system.
Claim 5
Dependent Claim
28 words
The method of claim 1, and further including the step of: C1) when the voice communication has concluded, determining whether the first multi-channel communication path should be maintained.
Claim 6
Dependent Claim
55 words
The method of claim 4, wherein step C1 further includes the steps of: C1a) determining whether the first multi-channel communication path then supports any other communications between the first and second radio frequency communication systems; C1b) when the first multi-channel communication path does not then support any other communications, dropping the first multi-channel communication path.
Claim 7
Dependent Claim
41 words
The method of claim 5, wherein step C1 further includes the step of: C1c) when the first multi-channel communication path does then support another communication, determining whether any other communication paths exist between the first and second radio frequency communication systems.
Claim 8
Dependent Claim
52 words
The method of claim 6, wherein step C1 further includes the step of: C1d) when another communication path so exists, determining whether all of the communications then being supported by both the first multi-channel communication path and the other existing communication paths can be supported by a smaller number of communication paths.
Claim 9
Dependent Claim
33 words
The method of claim 7, wherein step C1 further includes the step of: C1e) when a smaller number of communication paths will support the existing communications, reducing the number of existing communication paths.
Claim 10
Dependent Claim
52 words
The method of claim 8, wherein step C1 further includes the step of: C1f) when the number of existing communication paths are reduced because a smaller number of communication paths will support the existing communications, reassigning communications that were assigned to communication paths that were dropped to communication paths that were retained.
Claim 11
Independent Claim
124 words
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.
Claim 12
Independent Claim
124 words
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.
Claim 13
Dependent Claim
40 words
The method of claim 10, and further including the step of: D) when either the first communication path does not exist or the first communication path has insufficient capacity, automatically establishing a new communication path to support the voice communication.
Claim 14
Dependent Claim
24 words
The method of claim 11, and further including the step of: E) when the new communication path is automatically established, beginning a connection timer.
Claim 15
Dependent Claim
38 words
The method of claim 12, and further including the step of: F) when the connection timer indicates that at least a predetermined period of time has passed, determining whether the new automatically established communication path should be maintained.
Claim 16
Independent Claim
155 words
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.
