Abstract

All existing services that can be offered in one telecommunication network can be offered across networks without changing any existing interfaces and protocols. A mediation access processor (MAP) is provided in a network element located in a first network that is interconnected with a second network. The MAP provides screening, translation and emulation functionality, so that (a) messages transmitted between switches in the first network and SCP'"'"'s or other application processors in the second network can be properly converted so as to be recognized and understood, (b) changes to the intercommunication arrangements of the switches and the SCP'"'"'s, such as the protocols that are supported, are not necessary.

Claims

a mediation access processor (MAP) located in said first network, and

means for connecting said MAP to other elements in said first network and to network elements in said second network,

wherein said MAP includes modules for (a) screening messages transmitted in one direction between elements in said first network and elements in said second network, and (b) emulating, with respect to said first network, elements in said second network, and with respect to said second network, elements in said first network.

2. Apparatus for interconnecting first and second networks so that intelligent network services can be provided to a caller connected to said first network using call processing logic residing in said second network, said apparatus comprising

at lease one switch in said first network adapted to receive a call from said caller;

at least one network element in said second network arranged to store said call processing logic;

a mediation access processor (MAP) located in said first network; and

means for connecting said MAP to said switch in said first network and to said network element in said second network;

wherein said MAP is arranged so that messages transmitted between said switch in said first network and said network element in said second network are converted so as to be recognized and understood by said network element.

3. The invention defined in claim 2 wherein said network element is a Service Control Point (SCP).

4. The invention defined in claim 3 wherein messages between said switch and said MAP are in a first format and messages between said MAP and said network element are in a second format.

5. The invention defined in claim 4 wherein said first format is AIN (Advanced Intelligent Network) 0.1 INAP (Intelligent Application Network Protocol), and said second format is ETSI (European Telecommunications Standards Institute) CORE INAP.

6. The invention defined in claim 2 wherein said MAP (Mediation Access Processor) is disposed within an SCP (Service Control Point) in said first network.

7. The invention defined in claim 2 wherein said MAP (Mediation Access Processor) includes a screening module arranged to protect the network from unwanted or erroneous messages, and protocol identification and coordination modules arranged to translate messages from one INAP (Intelligent Application Network Protocol) option to another.

8. The invention defined in claim 2 wherein said MAP (Mediation Access Processor) operates a SSF/CCF (Service Switching Function/Call Control Function) to SCF (Service Control Function) interface as though it is an SCF, and operates at the SCF to SSF/CCF interface as though it is an SSF/CCF.
