System Description

PROTEI SMSC is a well proven SMS and USSD messagingplatform that receives, processes, stores, and sends allkinds of Short Messages (SMS) within a mobile networkor between a mobile network and external applications(ESME). PROTEI SMSC also supports USSD services on thesame software and hardware platform, widening themessaging services spectrum available for PROTEI SMSCcustomers.

PROTEI SMSC is a cost-effective, high performance andscalable solution with a wide range of features to suit bothnew and existing mobile operators and content providers.It also offers substantial cost savings to operators who havealready deployed large scale SMSCs and are looking fora lower-cost or easier-to-use solution to maximise trafficrevenues and profits.

PROTEI SMSC scalable architecture and flexible throughputlicensing enables the operator to select a solution that notonly mirrors the revenue stream of today, but can be used tomeet his future needs.

The range of protocols supported allows PROTEI SMSC tobe deployed in GSM or IS-41 (D-AMPS, CDMA) networks.SIGTRAN support allows easy integration into nextgeneration mobile networks. Reach system functionalityallows SMSC to be adapted to suit the operators needs.Flexible delivery scenario management allows the operatorto define message delivery scenarios on the base of Alertmessages, or schedules on the base of the error code froma previous delivery attempt. Its embedded First DeliveryAttempt feature dramatically increases system throughputand reliability on the same hardware when comparedwith traditional solutions. PROTEI SMSC can efficiently workwith queues up to 1 million messages in length. The policymanagement subsystem allows groups of numbers withdifferent access rights (e.g. numbers that dont have accessto SMS VAS) to be defined. Convenient licensing principles(no licensing by peak load) allow the operator to workefficiently during traffic peaks (like at New Year or otherpublic holidays).

With no bottlenecks and no single point of failure, PROTEI

SMSC constantly delivers dependable high performance.

Additional Messaging Applications

wide range of additional applications is available toaugment the spectrum of services available on the base ofthe PROTEI SMS/USSD messaging platform.

Customer Care ServicesA Customer Care software package is available for PROTEISMSC. It allows operators to provide standard customercare services such as balance information or voucheractivation via USSD or SMS. Integration with the operatorsbilling system is carried out on installation.

Fixed Line SMSC

The Fixed Line SMS Center allows SMS messages to beexchanged within a fixed-line network and between fixed-line and mobile phones. Superior functionality and flexible

configuration ensure easy deployment and integration intoexisting systems.

Standalone USSD ServerBuilt for USSD message exchange between mobilesubscribers and external applications in GSM networks,PROTEIs USSD server is the easiest and most effectiveway for mobile network operators to provide balanceinformation, voucher activation and other customerservices. The USSD server provides flexible message routingbased on service key, message body and MSC sourceaddress.

Access policies and bandwidth allowances can be

managed separately for each application. USSD phase1and phase 2 are supported, allowing interaction with USSDservices via a multi-level USSD menu. Embedded tools aidthe creation of flexible, user-friendly menus. The systemsupports open XML and/or ODBC interface for integrationwith external applications and databases.

SMPP Proxy/RouterDesigned for use by network operators or content providers,the SMPP Proxy/Router transfers SMPP messages betweenone or more SMS/USSD centers and external applications. Itis capable of flexible processing by message type, sender/recipient numbers, application IP address etc, making it akey element in access control systems for content providers.

SMS-to-ICQ Gateway

The SMS-to-ICQ service allows mobile subscribers andICQ users to exchange messages via SMS. A selectionof standard ICQ functions is supported (send/receivemessages, manage online status, register as a new ICQ user,search for contacts using UIN or e-mail etc.) Connects tothe SMSC using SMPP and with ICQ Servers using XML.

Global SMS ServerProvides access to SMS VAS services via a universalinternational number, accessible from any GSM networkwhich has negotiated SMS messaging with the GlobalSMS service provider. All the operators SMS VAS becomeavailable for inbound roaming visitors, in creasing revenuesboth directly (revenue generation from SMS VAS usage) andindirectly (making the network more attractive for roamers).

E-mail SMS GatewayThe SMS-to-Email service allows mobile subscribers and e-mail users to exchange messages via SMS. A selection ofbasic e-mail functions is supported (send/receive messages,basic account management, etc.) Communicates with theSMSC via SMPP v3.4 and with e-mail servers via SMTP.

SMS SenderSMS Sender is a powerful, user-friendly system for massSMS distribution. SMS sending lists can be created frompredefined lists and message bodies. Lists can be createdautomatically using information from external databases(for example, billing information) or manually by the systemadministrator. Individual parameters can be set for eachsending list, such as delivery schedule and data source. Asimple multilingual graphic interface makes the system easy

for non-technical departments (e.g. marketing) to use.

System ArchitecturePROTEI SMSC consists of severalsubsystems, each responsible for its ownspecific task.

PROTEI SMS/USSD Gateway is part of thePROTEI SMSC, where it is responsible forSS7 stack support, interaction with otherPLMN components and MAP to SMPPconversion, thus the gateway can be used

as an independent device for providingan offload SMS delivery service to protectthe SMSC from unnecessary traffic.

Often SMS messages addressed to PLMNsubscribers who are already active in thenetwork do not need to pass through theSMSC, since the message will be deliveredimmediately. Therefore SMS messagescan be passed to the PROTEI SMS/USSDGateway, which will attempt one deliveryof the SMS to the specified subscriber. Ifunsuccessful, it will then send the messageover SMPP to the executing mobileoperators SMSC.

In the PROTEI SMS/USSD Gatewayconfiguration system, the administratorcan specify if the text message is to bepassed to the SMSC on delivery failure, orif just the error code should be returned tothe ESME. This functionality is often usefulfor SMS messages that contain informationwhich is only relevant for a short time, suchas stock quotes.

The Postponed Delivery Subsystemimplements postponed delivery functionsincluding storage of delayed messagesand message queuing.

Subsystem for Statistical and AccountingInformation Collection collects statistical

and accounting information (CDR,message counters, error counters) relatedto system operation (SMS registration logs,SMS delivery attempts logs etc.).

The Administration and MaintenanceSubsystem is used for administering andconfiguring the system and also to monitorsystem performance (to receive event andalarm information from the system).

ESME Traffic Management

To guarantee high preformance whenworking with external applications, trafficfrom external applications to the GSMnetwork can be limited. Limitations canbe applied to the rate of transfer or to thenumber of messages that can be sentduring a specified time interval. The systemwill either accept or reject a new messagefrom an ESME according to the limitingthresholds set by system administrator. Thisfeature can also protect the messagequeue from overflow, even in the event

that no messages can be sent.

System Scalability and Reliability

PROTEI SMSC is a horizontally scalablesystem; if the load on one of thesubsystems (SS7 gateway, SMS server orreports and statistics server) reaches its setthreshold, excess traffic is transferred toa free module. High redundancy ensuresoptimal system availability.

If a module fails, traffic is redistributedamong other modules until the failedmodule becomes available again, withno interruption to service. Similarly, newmodules can be put into operation without

interrupting service flow.
