Communication system to communication system gateway method and apparatus
First Claim
1. A method, comprising the steps of:
- receiving a call request from a first radio frequency (RF) communication system to support a communication request from a sourcing communication unit, which call request includes a first identifier for at least one target communication unit;
automatically using the first identifier to determine a second identifier for the target commnuication unit, which second identifier is different from the first identifier;
automatically using the first identifier to request provision of RF resources in the first RF communication system to support the call request, and using the second identifier to request provision of RF resources in at least one RF communication system other than the first RF communication system to support the call request;
after receiving sufficient RF resources to support the call request, and prior to the sourcing communication unit starting a call, automatically sourcing call start information to each of the first RF communication system and the at least one RF communication system other than the first RF communication system to facilitate use of the RF resources to support the call request in the first RF communication system and in the at least one RF communication system other than the first RF communication system.

Abstract
A method and apparatus of linking communication systems of different types. Call requests are directed from a sourcing communication unit in a first communication system (101) to a gateway (114), which translates identity and call type information from the first system to at least one other system (113). Next, the gateway requests radio frequency (RF) resources from each system to support the call. After sufficient RF resources have been received, and prior to the sourcing communication unit starting a call, the gateway (114) issues call start information to each of the communication systems (101, 113). Then, the gateway (114) is operable to receive and translate a message payload from the sourcing communication unit and distribute the translated message payload to communication units in the at least one other system.

10. A method, comprising the steps of:
-
receiving a secondary resource request from a first radio frequency (RF) communication system to support a primary resource request from a sourcing communication unit, which primary resource request includes a first identifier for at least one target communication unit; automatically using the first identifier to determine a second identifier for the target communication unit, which second identifier is different from the first identifier; automatically using the second identifier to request provision of at least one RF resource in at least one other RF communication system to support the secondary resource request; after receiving sufficient responses to the request for provision of at least one RF resource in at least one other RF communication system, and prior to the sourcing communication unit starting a call, automatically providing information regarding the secondary resource request to the first RF communication system; when receiving call start information from the first RF communication system, automatically using the call start information, to cause the at least one other RF communication system to facilitate use of the at least one RF resource to support the secondary resource request. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
