AppSMSC

Short Message Service (SMS) continues to be the most popular data application in the mobile network

services market. The growing use of SMS as an application traffic bearer has changed the nature of traffic

flowing over the network. Conventional message transport infrastructure, primarily meant to handle non-

burst mode, person-to person (P2P) traffic, must now expand to accommodate high-volume application-to-

person (A2P) traffic flows. With operators needing to provide a comprehensive range of data services to

differentiate their offerings in the market, network capacity requirements can overwhelm current SMSC

resources, which are not designed to handle traffic spikes.

Bharti Telesofts AppSMSC is a dedicated message center to process and deliver intra-network and inter-

network application message traffic. The system allows cross-network message transmission via long

number allocation to applications. To meet varying performance requirements for multiple classes of

applications, the system supports multiple delivery modes including store and forward as well as first

delivery attempt for latency-sensitive, real-time applications such as news alerts and televoting. Reduction in

message buffers and functional independence of A2P message streams from P2P SMS flows on the

network, optimizes throughput, safeguards SMS infrastructure against overloads and secures QoS for all

traffic classes.

GUI-based Application Provisioning and Management framework enables immediate service provisioning

and deployment, allowing operators to rapidly deploy and manage applications on the network.

AppSMSC is built on modular standards-based architecture to ensure seamless network integration. The

support for multiple standard APIs enables seamless integration with popular, applications such as tele-

voting as well as heterogeneous MSC nodes.

AppSMSC Architecture

Comment Enterprise Linux

Atul Madan, VP VAS, Bharti Telesoft, remarks, High traffic volumes characterize A2P messaging but the

revenue generated from each message is lower than P2P messaging. Price-performance benefits assume

critical significance for operators deploying the AppSMSC. We standardized on Red Hats field-proven open-

source technology as it is lowers total cost of ownership and ensures consistent and reliable high

performance.

SMSC

Short Messaging Service (SMS) contributes a significant proportion of an operators non-voice revenues, In

the wake of sustained upsurge in SMS traffic flows, operators need a reliable transport solution that can

optimize the network to cope with the complex and constantly evolving messaging needs.

Bharti Telesoft SMSC is an efficient and high-performance SMS delivery and traffic management solution to

enable operators optimally manage and grow messaging traffic. Adaptive, efficient delivery algorithms

assure on time, reliable message delivery. Based on message transaction type, operators can deploy either

the store and forward or SMS direct transmission modes. SMS Direct delivers the message to the handset,

using the store capabilities only as a fallback delivery mechanism in event of failure. Flexible message

transmission, combined with configurable retry algorithms optimizes use of deployed capacity and prevents

system overloads.

In addition, the SMSC offers a range of controls for granular management of peak traffic flows including rate-

shaping techniques for inbound and outbound message transmissions, real-time buffer management, and

congestion detection monitors to maintain an optimal balance between demand for messaging resources

and deployed capacity.

Standards-based architecture ensures seamless integration between Bharti Telesofts SMSC and network

elements and allows operators extend throughput.

Atul Madan, VP VAS, Bharti Telesoft, comments, The SMSC is a resource-intensive system, as it

simultaneously supports person-to-person messaging and multiple third party applications. The underlying

Red Hat operating system maximizes system efficiency by optimally scheduling resources to manage

several process workload instances. In addition support for system redundancy ensures stringent adherence

to uptime requirements for mission critical SMSC infrastructure.

AppMMSC

Application-to-Person (A2P) messaging is driving the take-up of Mobile Multimedia Services (MMS).

Advances in high-speed network bandwidth, the proliferation of smart handsets, and the increasing

acceptance of the mobile phone as a lifestyle device make MMS an ideal way for third party content

providers to deliver rich multimedia content services. However, operators face a challenge, as these

services add new levels of complexity to message distribution - A2P traffic involves sending one message to

many subscribers, is typically bursty and when associated with time-sensitive bulk events, requires highly

scalable infrastructure to achieve prompt message delivery.

Bharti Telesofts AppMMSC provides high-performing, high-capacity multimedia messaging for mass-scale

distribution of revenue-generating lifestyle multimedia broadcasts such as video clips and audio snippets. A

dedicated transport infrastructure efficiently processes bursty A2P multimedia traffic, reducing the load on

the primary MMSC that mainly handles P2P MMS traffic Inbuilt routing algorithms efficiently regulate the

scheduling, buffering, and delivery of application traffic flow over the network. In addition, a web-based

framework simplifies application management and provisioning for rapid content rollout and user related

profiling, which includes device type to adapt content to the handsets capabilities as well as to determine

the delivery destination - the hansdet or an online MMBox.

The underlying high-performance Multimedia Message Delivery and Management Platform can be easily

integrated with existing network infrastructure (WAP, SMS, Billing, Prepaid systems etc.), regardless of the

vendor and third party applications.

Comment Enterprise LinuxAtul Madan, VP VAS at Bharti Telesoft comments, A2P multimedia messaging is a growing revenue

segment and operators are introducing compelling multimedia applications in line with evolving consumption
