Abstract

A service platform in a communications network connects callers to a service resource platform when implementing services requiring specialized resources. A number of different services use a common service resource platform. The service platform is programmed with respective maximum values for the number of calls originating from each service that may be connected to the service resource platform at one time and allows the call to be connected to the service resource platform only when the count value for the respective service is less than the maximum count value. The service resource platform may have a single network address and a common range of ports that are freely allocated to calls generated by the different services running on the service platform.

Claims

1. A method of operating a communications network including a plurality of network switches, a service platform connected by a signalling interface to the plurality of network switches, and a service resource platform, the method comprising:

when a service provisioned for a party to a call requires service resources from the service resource platform then, under control of the service platform, connecting a party to the call via a network switch to the service resource platform;

for each of a plurality of different services requiring the service resources of the service resource platform, maintaining a count of the respective number of ongoing calls concurrently connected to the service resource platform;

storing for at least one of the plurality of services a maximum count value; and

connecting a further call to the service resource platform when the count maintained for the said service is less than the maximum count value.

2. A method as in claim 1, in which the service resource platform has a single network address and a plurality of ports associated with said single network address, and a common range of ports are accessed by the plurality of services.

3. A method as in claim 1 comprising storing the said count of the respective number of ongoing calls connected to the service resource platform for each of the plurality of different services in an overload control server connected to the service platform.

4. A method as in claim 1 in which the service platform includes a plurality of transaction servers and in which, in the step of maintaining a count, a separate count is maintained, for each service, for each of the plurality of transaction servers.

5. A method as in claim 2 comprising storing the said count of the respective number of ongoing calls connected to the service resource platform for each of the plurality of different services in an overload control server connected to the service platform.

6. A method as in claim 2 in which the service platform includes a plurality of transaction servers and in which, in the step of maintaining a count, a separate count is maintained, for each service, for each of the plurality of transaction servers.

7. A method as in claim 3 in which the service platform includes a plurality of transaction servers and in which, in the step of maintaining a count, a separate count is maintained, for each service, for each of the plurality of transaction servers.
