Mobile Communications

As a result of our long standing partnership with Ecrio Inc, we have acquired significant knowledge of software technologies used in packet switched communications over wireless networks. This includes in-depth knowledge of the SIP, RTP/RTCP, MSRP protocols and Sigcomp solution especially with reference to the specific requirements for IP Multimedia System (IMS) enabled services as laid down by 3GPP and IETF and also other protocols such as XCAP, HTTP and XDM standards as required by Open Mobile Alliance (OMA). We also have experience with the Diameter protocol which is extensively used between various components in the IMS network.

We have worked on a number of applications targeted towards 3G networks

• Video Share allows users engaged in a circuit switch voice call to add a unidirectional video streaming session over the packet network during the voice call. The source used for the video can be live from camera or can be a pre-recorded video clip.

• Push to Talk over Cellular is a walkie-talkie like feature for mobile phones with a notion of a “floor” which allows half duplex communication among members of a chat group. The benefit of PoC is that it allows a single person to reach an active talk group at a button press, without having to make several calls to coordinate with a group.

• Voice Call Continuity (VCC) is an application which seamlessly transfers a Voice Call between the circuit switched and packet switched call legs on a Dual Mode handset as and when the radio conditions change.

• Enhanced Address Book
The Wireless Association® (CTIA) Enhanced Messaging and Rich Communication Suite (RCS) initiative aims to speed up the evolution of mobile phone communication towards rich communication. It has laid down the specifications for an enhanced address book which provides service capabilities and presence information.

Besides IMS applications, we have experience with the OBEX APIs for Bluetooth which we have used extensively to implement the PBAP, Sync and MAP profiles. We have also developed applications on handsets using J2ME.

• Software Testing
Functionality Testing – Determines the extent to which a product meets expected functional requirements through validation of product features.
Performance Testing – Determines how quickly the product executes a variety of events. Benchmarking of a product against the competition also falls under this head.
Load Testing - Checks how well a product functions when it is in competition for system resources such as CPU, I/O processor, network, memory etc.
Stress Testing - Determines, to a deeper extent than load testing, the capacity of a system by increasing the load placed on the resources until a failure or other unacceptable product behavior occurs.
Installation Testing – Checks how well and how easily a product installs on a variety of platform configurations.
Website Testing –
o Ensures that the site functions properly.
o It is compatible across different platforms and configurations.
o Can handle large number of concurrent users.
Automated Testing - Test automation becomes useful when the same set of test cases is to be executed repeatedly. This becomes useful specially, when the development team follows a RAD methodology wherein the software is evolved through multiple builds and delivery.
Test tools evaluation and implementation – There is a plethora of test tools available in the market that address a variety of needs for software testing. We can help the customer in assessing the needs for automated testing, selecting an appropriate test tool and integrating the test tool with the testing process, seamlessly.
