What is Service Broker ?
Service broker is a service abstraction layer between the network and application layer in telecom environment. SB( Service Broker ) enables us to make use of existing applications and services from Intelligent Network’s SCP ( Service control Point ) , IMS’s Application Server as well as other sources in a harmonized manner.
The Service Broker Application Server provides the services in various permutations and combinations. Examples: Mobicents / Rhino TAs for Jainslee SBB , or Weblogic / Sailfin for Sip servlets.
What is Service Orchestration ?
The Process of Orchestrating various service to provide a single flow control is refereed to as Service Orchestration.
What is Service Harmonization ?
I have tried to simplify the concept by visualizing different boxes of various communication platforms as SIP, HTTP , CAP 1/2/3/4 , SMTP etc and then imagining a system that caters to all of these . It is primarily important that the billing and chagrining system remains common to all the sources and protocols be it 2G , 3G or 4G based. A post on service harmonization between various telecom generations is at

The next writeup Service broker 2 is :
Service Broker 2
This contains the Defination and purpose of using a Service broker as well as its role in network enviornment. It also contains service broker functions like Real-Time Charging , Protocol/Call Flow Management/Call Screening Management , Subscriber Data Management Interaction, Media Resource Brokering.
Details of Service Broker implementation in IN and IMS is at article below. Details on Service Broker and how service provider acts as a central Node for Services invocation and services composition is described in this. It clearly shows Service Broker provides Services Orchestration / Interaction, service development, third party integration and acts as a protocol gateway.
OTT ( Over the Top ) Communication applications
Market trends are not in favour of Telecom Service /providers with increasing use of OTT ( Over The Top ) applications like WhatsApp, Facebook messenger, Google hangouts, skype, Viber, etc. OTT applications are often blamed to take a stake in voice traffic revenue by using IP calls where the telco could’ve charged based on its…
Service Creation Environment (SCE ) for SIP Applications
Develop a SCE ( Service Creation Environment ) to addresses all aspects of lifecycle of a Service, right from creation/development, orchestration, execution/delivery, Assurance and Migration/Upgrade of services.
Harmonization of services between generations of telecommunication core layers
A communication system can be made up of many components which are individually undergoing evolution such as access layer generations, and core layer upgrades. Harmonized and uniform open standard-based service delivery platforms over legacy Proprietary codebase is the preferred choice for most service providers to save the investment in their infrastructure and programming while keeping…
We have already learned about Sip user agent and sip network server. SIP clients initiates a call and SIP server routes the call . Registrar is responsible for name resolution and user location. Sip proxy receives calls and send it to its destination or next hop. Presence is user’s reachability and willingness to communicate its…
Legacy Telecom Networks
I use the term legacy telecom system many a times , but have not really described what a legacy system actually is . In my conferences too I am asked to just exactly define a legacy system . Often my clients are surprised to hear what they have in current operation is actually fitted in…
SIP/VOIP transformation towards IMS (Total IP)
The telecommunications industry has been going through a significant transformation over the past few years. At the outset incumbent operators used to focus on mainly basic voice services and still remained profitable due to the limited number of players in the space and requirement of huge amounts as initial investment. However, with the advent of…

Telecommunications convergence – VoIP, PBX and IMS
The signalling protocols migration like from signalling system 7 (SS7) to session initial protocol (SIP) have been taking place in Telco-Industry. Similarly nodes of legacy network like signal transfer point (STP) of legacy network are being migrated to call session control function (CSCF) of IMS that allows the rapid development and deployment of enhanced, revenue-generating…
One thought on “Service Broker 1”
Brilliant have not seen something like this so far .. good on you for explaining Service brokers
