Communication system supporting remote operations
DCFirst Claim
1. Apparatus for effecting resource allocation remote operations in a pair of communication systems utilizing Open Systems Interconnect communication protocol, comprised of means within respective ones of said communication systems for generating predetermined operation data signals associated with an invoking Application Entity;
- means for transmitting said data signals between said communication systems in accordance with said protocol; and
means within said communication systems for receiving said data signals and in response allocating a server Application Entity performing said remote operations;
each of said operation data signals including a n Invoke Address signal for identifying said Invoking Application Entity, and a Server Address signal for identifying said server Application Entity, whereby said operation data signals are directed to respective ones of said invoking and server Application Entities identified by said Invoke Address and Server Address signals, a first one of said operation data signals being comprised of an invoke operation signal generated by said invoking Application Entity within a first one of said pair of communication systems and transmitted to said server Application Entity within the other of said pair of communication systems for invoking performance of a predetermined one of said remote operations via said server Application Entity.

Abstract
A communication system for implementing remote operations between a PABX and a host computer, conforming to Open Systems Interconnect (OSI) communication protocol. Circuitry is provided in each of the PABX and host computer for generating and encoding invoke, return result, error and reject operation protocol data unit signals, for transmission between application layer entities of the PABX and host computer. In order to support invoking of asynchronous telephony operations, invoke address and server address fields are incorporated within the argument sequence and the result sequence of the invoke and return result operation protocol data unit signals, respectively.

13. A method of communicating for implementation of remote operations within two communication systems, conforming to Open Systems Interconnect communication protocol, comprising the steps of:
-
(a) generating and encoding an invoke operation signal associated with a predetermined Application Entity allocated within a first one of said communication systems, said invoke operation signal including an Invoke Address signal for identifying said predetermined Application Entity, (b) transmitting said invoke operation signal from said first communication systems for reception by the other of said communication systems, (c) receiving said invoke operation signal within said other communication system, and in response allocating a further Application Entity therein for performing a predetermined remote operation, (d) generating an encoding a result operation signal associated with said further Application Entity, said result operation signal being comprised of said Invoke Address signal, a Server Address signal for identifying said further Application Entity, and an argument data signal specifying predetermined parameters resulting from performance of said predetermined remote operation, (e) transmitting said result operation signal from said other communication system for reception by said first communication system, and (f) receiving and routing said result operation signal within said first communication system to said first Application Entity identified by said Invoke Address signal, whereby performance of said predetermined remote operation is acknowledged. - View Dependent Claims (15, 16)

14. A method of communicating for implementation of remote operations within two communication systems, conforming to Open Systems Interconnect communication protocol, comprising the steps of:
-
(a) generating and encoding an invoke operation signal associated with a predetermined Application Entity allocated within a first one of said communication systems, said invoke operation signal including an Invoke Address signal for identifying said predetermined Application Entity, (b) transmitting said invoke operation signal from said first communication system for reception by the other of said communication systems, (c) receiving said invoke operation signal within said other communication system, and in response allocating a further Application Entity therein for performing a predetermined remote operation, (d) generating and encoding an error operation signal associated with said further Application Entity, said error operation signal being comprised of said Invoke Address signal, A server Address signal for identifying said further Application Entity, an error code signal for identifying a predetermined error made in attempting to perform said predetermined remote operation, and a parameter data signal specifying predetermined parameters of said error, (e) transmitting said error operation signal from said other communication system for reception by said first system, and (f) receiving and routing said error operation signal within said first system to said first Application Entity identified by said Invoke Address signal, for acknowledging failure to successfully complete said predetermined remote operation which performance was attempted by said further Application Entity.

17. A method of communicating for implementation of remote operations within two communication systems, conforming to Open Systems Interconnect communication protocol, comprising the steps of:
-
(a) generating and encoding an invoke operation signal associated with a predetermined Application Entity allocated within a first one of said communication systems, said invoke operation signal including an Invoke Address signal for identifying said predetermined Application Entity, (b) transmitting said invoke operation signal from said first communication system for reception by the other of said communication systems, (c) receiving said invoke operation signal within said other communication system, and in response allocating a further Application Entity therein for performing a predetermined remote operation, (d) generating and encoding a reject operation signal associated with said further Application Entity in the event of reception of a malformed invoke operation signal resulting in the further Application Entity failing to perform said predetermined remote operation, said reject operation signal being comprised of said Invoke Address signal, a Server Address signal for identifying said further Application Entity, and a problem data signal for specifying the cause of rejection of said malformed invoke operation signal, (e) transmitting said reject operation signal from said other communication system for reception by said first system, and (f) receiving and routing said reject operation signal within said first system to said first Application Entity identified by said Invoke Address signal, for acknowledging ejection of said malformed invoke operation signal by said further Application Entity.
