Architecture

Short Message Service Center (SMSC)

This has been one of our front line products in messaging. The SMSC is responsible for receiving, storing and forwarding short messages in a mobile network. It supports Mobile Originating (MO) and Mobile Terminating (MT) text messaging. It has been in operation since 2003, deployed in A2P and P2P Scenarios handling the main messaging requirement of Operators. The system has been reliable and performance wise stable in handling millions of SMS traffic daily. To date Wavenet Prime SMSC serves more than 50 Million subscribers daily strengthening MNOs around the world.

 

End to end SMS handling with First Delivery Attempt (FDA)

Nowadays the rate of success for a SMS to be delivered is more than 90 % and the need for storing a SMS in the SMSC isn’t a must. With FDA the messages are directly delivered to subscribers in the first attempt reducing the hardware requirement and increasing service efficiency. Messages will be directly delivered to the network via SS7 reducing the load on the SMSC. If the message is not delivered it will be saved in the message store to be delivered later.

Store & Forward messages

SMSC supports store and forward mechanism which guarantees message delivery in failure scenarios. The delivery failed or differed messages will be saved in the message store to be resend when available.  

Advance routing capability

Prime decodes messages in to its protocol layer exposing packet information which will be used in advance routing. This gives better control and flexibility for the operator to do complex message routing.

Mobile number portability

MNP is offered in multiple methods via Prime SMSC enabling users to retain their mobile number when changing between operators.

Location based service support

LBS services are required to interrogate subscriber location from the network. Prime supports multiple mechanisms enabling location information passing from network to the applications.

Multiple error code support

Error code schemes can be defined in the SMSC to address different network behaviors and retry options. This can be also used in routing decision making to give added flexibility.

Unicode and Long message support

Short message support for more than 160 character in binary and Unicode delivered via multiple interfaces (SS7, SMPP & HTTP).

SMPP Support v 3.3, 3.4 and 5.0

SMPP is an open, industry standard protocol designed to provide a flexible data communications interface for the transfer of short message data between External Short Message Entities (ESME), Routing Entities (RE) and Message Centers.

Unstructured Supplementary Service Data (USSD)

PRIME has an inbuilt USSD gateway which can be used to facilitate the operator with the ability to handle USSD responses. The USSD services can be either push or pulled as and when the requirement presents itself. USSD services are one of the leading methods of reliable communication between applications and clients. This is widely used between operators and subscriber communication and is an essential service for all operators.

Summary of USSD Gateway functionality

  • Handle - Mobile initiated & Network initiated USSD sessions
  • USSD redirection via Sigtran & SMPP
  • Application redundancy ( USSD requests can be directed to multiple applications in a case of an application failure)
  • USSD dialogues (Multiple request & response in session)
  • User access Control (MSISDN & IMSI pattern match and black/whitelist checks)
  • Communicate to applications and Fusion Studio SCE through SMPP for USSD service creation
  • CDR generation
  • Logging

Multimedia Messaging Service Center (MMSC)

To make Wavenet Prime a more complete messaging solution the addition of MMSC was in-build on to the platform. The capability to handle Multimedia messages will give an upper hand to the operators, when it comes to competing for dominance. Wavenet MMSC has the capability to support person-to person (phone-to-phone) MMS messaging, as well as application-to-person and person-to-application MMS messaging. This allows widening the use of messaging to increase opportunities for the operators.

SMS Firewall

Messaging is still a prominent driver of revenue for an Operator regardless of the scale of operations. However, the revenue generated from messaging traffic is subject to severe threats such as grey routes, SPAM and international fraudulent SMSs where any vulnerabilities of the network infrastructure is exploited to mimic genuine traffic. This will cost Operators not only losses in terms of not being able to recuperate inter connectivity fees but network overload which can affect delivery of genuine revenue generating traffic and performance of the network. Compensations and complaint management by call centres for any fraudulent messages that subscribers have received can also add up to the costs that Operators incur. There have been instances of subscriber personal details being compromised as a result of SPAM messages and where subscribers have been billed unduly due to fraudulent messages. Regulations have become more stringent to protect subscriber rights and confidential information and security standards such as IR 70 and IR 71 are being heavily enforced by Regulators to Operators. Wavenet Prime Firewall is a holistic fraud prevention and network security solution which provides protection against all forms of network threats. It filters Mobile Originated messages (MO), Mobile Terminating messages (MT) and Application traffic (SMPP).

SPAM Detection
Subscribers are targeted by fraudsters to receive unsolicited SMS. These unintended messages tend to have various content including commercial information, bogus content, requesting of personal information which invites responses from the receivers. These messages can come through from a mobile user, external SMSC or a third party application. Wavenet SMS Firewall detects SPAM messages using multiple detection mechanisms which can be defined globally or network wise.

    • Known SPAM

SPAM content can be defined in the system for detection

    • Signature Matching

Signature mechanism is used to identify SPAM content which are circulating within the network creating unnecessary traffic . Chain messages & other SPAM can be identified using  partial matching, fuzzy rules & shuffled words.

    • Percentage Matching

A detection optimizer which uses percentages for signature matching.

    • Bayesian

Bayesian algorithm is used with a trained word database for content analysing.

Flooding Detection
In network flooding, exceeding number of unwanted messages are directed to the mobile network. Flooding can happen from MO, MT, SMPP & SRI requests which are originated for mobile devices or applications. Prime scans through total system and individual node traffic to detect security threats based on message frequency settings.

MO Spoofing
Spoofing is receiving messages with faked MSISDN which can leads to wrongfully charging customers and identity misuse. Spoofed MO messages can  from the MSC/VLR. Detection will be done analysing  signalling level information. Prime Firewall have functionality will be used to make an accurate decision. Once detected alarms can be triggered or automatic blocking is possible.

MT Faking
MT faking can be a issue for most operators and the threats can originate locally or internationally. Fraudsters use illegal links to  access the mobile network and terminate messages impersonating SMSCs. This will result in home operator terminating local or international SMS traffic without a return (termination charge).

GT Scanning
In GT Scanning Prime FW will monitor the originating point and the number of requests to determine security breaches.

Prime Firewall includes Real-time detection and blocking, Alarm triggering and Load balancing.
