Diameter Message Manipulations
The Oracle Communications Core Session Manager can perform manipulations on all grouped and non-grouped AVPs. This is referred to as Diameter Manipulation Rules (DMR). A message manipulation is the ability to search for a predefined string within an AVP and then replace it with another value. This is similar to the Oracle Communications Core Session Manager’s header manipulation rules functionality.
A diameter manipulation configuration element is defined by a name parameter. You can optionally add a description field to the diameter manipulation. Within each diameter manipulation you can configure multiple diam manipulation rule subelements. The manipulation rule subelements are the configuration where AVPs are identified, searched, and in which the data is replaced.
The user can apply diameter manipulations to external policy server configurations. These manipulations affect traffic between the Oracle Communications Core Session Manager and the applicable policy server.
Note:
The Oracle Communications Core Session Manager also supports diameter manipulation across the Cx interface, with the user configuring these manipulations to home subscriber server configurations. The range of manipulation supported over the Cx interface is the same as that over the Rx interface.
