Slide1: Multi-band, multi-mode Multi Protocol (GPRS/GSM/UMTS) Terminal Software e3MultiCom v3.1 By Nex-G Exuberant Solutions Pvt. Ltd.


Motivation: Motivation Customer demand for wireless handsets, PDAs and PCMCIA card is being increasingly driven by the need for seamless roaming across multi-technology network infrastructure, integrated applications requiring high bandwidth and lighter handsets. These requirements in turn, translate to the need for multi-mode, multiband protocol communication stacks,efficiently programmed embedded system device implementations, memory-efficient software implementation and low battery consumptions. e3MultiComTM is build for multi-band, multi-mode devices to allow subscribers to seamlessly roam between GSM, GPRS and UMTS networks using a common SIM card. Our stacks interface with SIM card, OS and RF hardware by employing a robust set of software API’s. As a consequence of which, memory optimization from common software modules and uninterrupted handover across heterogeneous network technologies can be realized.


Product Feature: Product Feature e3MultiComTM supports GPRS Class B, GPRS Class C and UMTS operations.It incorporates all the standard design features specific to GPRS and UMTS stack to enable efficient and easy application development Supports all GSM,GPRS and UMTS stacks MAC-G(For GPRS), MAC-U(For UMTS), RLC-G(For GPRS, RLC-U(For UMTS), RR,RRC, GMM, MM, LLC, SNDCP, PDCP, BMC , SM , SMS, CC and SS Frequency band of operation:Multi-band (GSM 900, GSM 1900, GSM 1800 and WCDMA) Medium Access Modes:- Fixed, dynamic and extended dynamic allocation (For GPRS) Coding Schemes:- CS1 – CS4 (For GPRS)


Product Feature (Contd…): Product Feature (Contd…) For GPRS, Paging Co-ordination for Network Mode – I, II, III SMS point-to-point SMS compression Cell broadcast Multislot 1-12 Compression based on RF2507 (IPv4 header compression for TCP/IP and UDP/IP data) FFR/FR/HR/AMR Codec Interface


Product Feature (Contd…): Product Feature (Contd…) Measurements Handover Transparent, Acknowledged and Unacknowledged mode RLC Ciphering and Compression in hardware PDP Context Activation/deactivation/modification procedure Support IPv4 and PPP Circuit Switched Data


Additional Features: Additional Features Full Conformance Testing using the e3NetSimTM (Conformance Tester) Effective isolation from OS and hardware dependencies through a set of API’s for easy porting across various environments Global release from common stack core e.g. Common GPRS and UMTS modules:GMM/SM/MM/CC/SMS


Interfaces: Interfaces JAVA Platform and API for application development AT command support for Terminal Equipment Interface SIM Interface API Platform Abstraction Interface API Layer 1 and Hardware Abstraction Interface API


e3MultiComTM Protocol Architecture: e3MultiComTM Protocol Architecture


Portability: Portability e3MultiComTM is designed for ready porting to a variety of target platforms.This is achieved by Exuberant Platform Abstraction Interface (EPAI) to abstract the stack software from the target platform environment


Platform Support: Platform Support e3MultiComTM stack is written in 'ANSI C'. The EPAI enables the stack to run on the Linux, Sun Solaris and several real time embedded systems.


Application Programming Interface: Application Programming Interface e3MultiComTM stack is interfaced using a rich set easy-to-use API’s. By using a modular design, the stack is easily integrated into different mobile devices environments.


Testing & Performance: Testing andamp; Performance e3MultiComTM stack is tested using industry standard test equipment and e3NetSimTM and is optimized for real-time and memory limited applications. More information on e3NetSimTM can be obtained from us on request.


Reliability: Reliability e3MultiComTM stack is rigorously tested at multiple levels. Unit Testing and Module Testing are performed during the stack development phase. System integration testing is performed where the stack is tested for conformance in accordance with the relevant ETSI specifications using the e3NetSimTM. Eventually, the integrated stack is tested for reliable operation using industry standard test equipment.


Adaptability: Adaptability e3MultiComTM stack architecture is designed for adaptability to various target and customer specific operating environments. A modular design approach enables the software to be quickly updated to the most recent specifications.


ETSI/3GPP Compliance: ETSI/3GPP Compliance e3MultiCom stack is compliant with 3GPP ETSI Specification Release 6.
