BRM is a product-based platform capable of supporting a wide variety of services and

markets. If you can count it, BRM can bill for it and help you manage the revenue life cycle of

your subscribers. It provides the following advantages to the service provider:

• Shorter time to market new service

• Configure complex plans for the services offered

• Allows bundling of services

• Allows cross-service discounts

• Reduce operating cost

• Presents a convergent view of customer’s services

The diagram in the slide shows the many services supported upon the BRM platform as a

base. Some of the depicted services include DSL, Fixed Wireless, IP Telephony, Web

Hosting, 3G Wireless, VPN, WiFi, and Satellite Radio.


As the diagram illustrates, Online Mediation Controller can be used in a large number of

scenarios for integrating BRM with different types of systems and networks where there is a

need for a charging and billing solution.



Signaling Server Units

When integrated with BRM, Online Mediation Controller communicates through the Portal

Communication Protocol (PCP), which is a native interface to BRM.

Signaling Server Unit (SSU) is a component that enables Online Mediation Controller to

connect to IMS-based networks through standard software and hardware interfaces. There is

a specific SSU implementation to support connection to each network domain.

Online Mediation Controller includes the following SSUs:

• SIP SSU, which provides access to SIP-based networks.

• Diameter SSU, which provides access to network entities that interact using the

Diameter protocol.

• PCP SSU, which provides access to the Oracle BRM application through the Portal

Communications Protocol (PCP)

• SMPP SSU, which provides access to Short Message System Centers (SMSC) through

the Short Message Peer-to-Peer (SMPP) protocol.

• Web Services SSU, which enables Online Mediation Controller to interact with external

entities that use SOAP or REST-based communication.

Online Mediation Controller can easily be extended to also support SS7-based networks

through the following SSU’s:

• SS7 SSU for TDM, which provides access to a legacy SS7 network through MTP

protocols.


Each connection pool is considered a PCP network entity. If one or more PCP network

entities act as one logical Oracle Communications BRM application, you assign one alias to

those network entities.


Interworking Modules (IMs)

IMs are a set of interchangeable modules through which Online Mediation Controller

communicates with applications and session control entities. Each IM provides connectivity to

a single application or network entity, through their native protocol.

There are two types of IMs:

• Network-facing IMs, connecting Online Mediation Controller to session control entities,

such as MSCs and Call Session Control Functions (CSCFs). Network-facing IMs

provide a stateful front-end to session control entities, thereby entities interact with

Online Mediation Controller in the same way they interact with applications.

• Application-facing IMs, connecting Online Mediation Controller to applications, such as

IN SCPs, SIP ASs, and OCSs. Application-facing IMs provide a stateful front-end to

applications, thereby applications interact with Online Mediation Controller in the same

way they interact with session control entities.

Orchestration Engine (OE)

The OE resides at the center of the Online Mediation Controller architecture. Sessions

arriving through IMs, invoke the OE, which routes the sessions through one or more

applications based on an orchestration logic that the OE obtains for each session. The OE

invokes applications in a specific order, according to conditions that determine which

application to invoke and in which order.


IM-OCF PCP translates Ro messages to PCP messages and communicates with BRM

applications using the Ro PCP mediator.

Use the Administration Console or Java Mbeans to configure IM-OCF-PCP:

• Define how IM-OFCF PCP handles sessions.

• Configure parameters related to the IM-OCF PCP Diameter Credit Control

Application (DCCA) interface.

• You can set up IM-OCF PCP to trigger an MRF to play announcements.

• Define how Runtime MBeans and notifications operate for an IM-OCF PCP.

• Define what to do with CDRs when entering Degraded Mode.

• Define how mediation between Ro and PCP occurs.


IM-OFCF PCP translates Rf messages to PCP messages and communicates with BRM

applications using the Rf PCP mediator.

Use the Administration Console or Java Mbeans to configure IM-OFCF-PCP:

• Define how IM-OFCF PCP handles calls.

• Define how Runtime MBeans and notifications operate for an IM-OFCF PCP.

• Define what to do with CDRs when entering Degraded Mode.

• Define how mediation between Rf and PCP occurs.


When the Orchestration Engine selects and retrieves an orchestration profile it uses the OPR

that you specified when configuring the OE.

You can specify one of the following OPRs:

• Default OPR

The OE uses this OPR to route a session based on the the static route OLP.

• HSS OPR

The OE uses this OPE to retrieve subscriber profiles from an HSS.

• LSS OPR

The OE uses this OPR to retrieve subscriber profiles from an SM-LSS.

• Custom OPR

This option is relevant for the Online Mediation Controller only. The OE uses this OPR

to retrieve subscriber profiles from the Subscriber Store. If the subscriber profile is

missing, the OPR returns the error, and the OE terminates the session.
