Abstract: Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for receiving a plurality of bills of material (BOMs), each BOM including a data structure defining items within a respective product, enhancing each BOM based on one or more attributes to provide enhanced BOMs, clustering the enhanced BOMs into two or more clusters, determining a matching cluster from the two or more clusters at least partially based on a BOM of a new product introduction (NPI), selecting a sub-set of predecessor products from the matching cluster, and providing the sub-set of predecessor products as the one or more recommended predecessor products for selection by a user.

Abstract: A method for tracing a session or call in a network environment, comprising the step of transmitting a trace invocation from a control plane network element to another control pane network element or a user plane network element. According to a first aspect, a trace report is generated in the S-CSCF of the called party. This overcomes the lack of being able to provide detailed information about the interworking between the User Equipment (UE) and the IMS, in setting up IP multimedia sessions. According to a second aspect trace reports are generated in all the network functions involved in session setup.
