A method of mediation of data packet traffic across a particular interface between the Advanced Intelligent Network operated by a local exchange carrier and a non-local exchange carrier service provider is disclosed. The interface is defined between a service provider and the Advanced Intelligent Network, and in particular, between a service provider's network device, such as a service control point (SCP), that has access to the Advanced Intellignet Network through SS7 protocol data links connected to a local exchange carrier device, such as a service transfer point (STP). Gateway screening at the STP is used to perform certain mediation steps with respect to data packets that originate with non-local exchange carrier network elements. A data packet with invalid values is rejected, but a data packet with valid values is passed for further mediation steps to a mediated access SCP. Prior to any further routing of the data packet (other than rejection of the data packet), the mediated access SCP removes information from the data packet that corresponds to information regarding the source of the data packet such as the transaction number of the data packet. The mediated access SCP stores this removed information, generates substitute information, correlates the removed information with the substituted information in its database, and replaces the removed information in the data packet with substitute information. The substitute information provides no information regarding network operations to the recipient of the data packet. Upon receipt of a responsive data packet, the mediated access SCP examines the responsive data packet for inclusion of the substitute information. If the responsive data packet does not include this substitute information, the data packet is rejected. If the responsive data packet includes the substitute information, and is otherwise valid, mediated access SCP correlates the substitute information to the removed information, and uses the removed information to further route the data packet. |
