Architecture & Interfaces

Core Gateway Architecture

Confidential Slide

SMSC Manager : This interface supports both SMPP and CIMD protocol. Responsible for send /receive operations and communication with SMSC.

Queue Manager : Request and response of the server are queued differently and handled with the help of

queuing mechanism. It is responsible for storing requests/responses and passing the same to different modules.

HTTP Manager : Responsible for performing the HTTP – hit operation to fetch the content from the Internet. Handles all HTTP error codes & take appropriate action.

Core Gateway Components

Callback Manager : Responsible for intimating the applications/agents which submit messages to the users.

PUSH Receive Manager : Accepts input from different Jataayu push servers. Communication between this module and push server is proprietary. Responsible for any Mobile Terminated push message submission through the Gateway.

Gateway Information Manager : Gives information about the SMSC channels to the Push Servers based on the trigger of

the event

Core component for Push operation. Takes input from external push applications using Push Initiator interface and submits the

message to the Gateway.

It has two sub modules :

Push Initiator Manager : It is responsible for all interaction with the push client. It establishes PI API interface with the external agents.

Gateway Manager : Responsible for all its communication with core gateway. It collects SMSC/Channel information from the core gateway and also informs the same to

PI Manager, which in turn updates the external applications.

Push Server Components

SMSC : Store and forward the SMS and deliver the SMS on available of the destination subscriber.

Internet Applications/Content Providers : Content for VAS is fetched from Content Providers through HTTP Interface.

Callback Applications : Status of the message submission is provided to external callback application through the

HTTP interface.

External Systems

CDR Processor : CDR generated by billing engine can not be delivered as it is to operators billing engine

hence external component CDR Processor CDR interacts with billing engine on one end and CDRs of core gateway on the other.

Confidential Slide

Push Applications : Applications can use the API interface provided for pushing the messages.

Web Administration : Various Operation and administration like start/stop, edit/update configurations, viewing

statistics and product information is available through Web/HTTP Interface.

Confidential Slide

SMPP/CIMD are SMS Protocol used for SMSC interfaces.

HTTP Interface is used for fetching the content and providing the callback interface.

CDR interface used for billing by CDR processor on one end.

PI (Push Initiator API) interface is used by external applications to communicate with Push Server.
