Virtual Sy to extend the PCRF functionality
Virtual Sy to extend the PCRF functionality. Modern PCRF systems support multiple Sy links to integrate more than one online charging system (OCS) into the network. Though a particular subscriber can be coupled with a specific OCS, various subscriber segments can be integrated into different ones. The traditional postpaid is the best candidate as it does not interact with any OCS. Integration of high latency node with low latency node Though Diameter Protocol is asynchronous by design, response latency is critical. A lightweight node can implement the Sy interface with default or cached status as functionality for PCRF-initiated messages (SLR). In Addition, a spin-off workflow can trigger a high latency node to compute the policy changes and reflect through OCS-initiated messages (SNR). This will trigger PCRF to re-evaluate the policy and implement a re-authentication request (RAR) if needed. Use Case : Policy control via de-coupled traffic analyzer Virtual Sy can query the...
