Solution Overview

A-SMSC Solution.

Description• A-SMSC (Application Short

Messaging Service Center) is a scalable and resilient solution for receiving, storing and forwarding short messages for mobile originated and mobile terminated application traffic

Operator Benefits• Facilitates application messaging

• Reduces operator's infrastructure and messaging costs

• Offloads application-centric traffic from current SMSCs


Provides full power to the operator.

Full SS7 operations support.

On the SS7 side, the A-SMSC supports the following operations:

- Incoming MT Message - messages from other SMSCs for a virtual MSISDN.

- Incoming MO Message - on-net mobile originated messages.

- Incoming HLR Notifications.

- Outgoing MT Messages - generated by an application.

- Outgoing MO Messages - generated by an application (reverse billing).

- Outgoing Report Delivery Status.

A-SMSC features


- Protocols such as SMPP, UCP, CIMD2 to integrate with anyapplication, including a new Java API that reduces signaling traffic.

- Interactivity with the HLR through message waiting data flag and alert-service-centre.

- Querying of handset status and status delivery reports.

- Efficient store-and-forward with configurable retry schemes (e.g. based on MAP error codes, reducing unsuccessful retries).

- Ability to set validity periods and deferred delivery.

- Enhanced service offering, e.g. possible to send messages to a mobile subscriber only when the user is not roaming (least-cost routing by reducing foreign termination / interconnection fees).

A-SMSC features (cont.)

Increased SMS routingand message handling possibilities.


• SMS Gateway

- Protocol conversion to legacy SMS protocols

• Connection Protocol

- ASN.1 based TCP protocol (internal use)

• A-SMSC Protocol

- Java API

- Simple ASCII based TCP protocol

A-SMSC provides several interfaces for applications.

• Most often implemented cross networkapplication solution in the world.

• Implemented at e.g. MTN South Africa, TDC Denmark, WIND Italy, sunriseSwitzerland, Vodafone UK, O2, Cingular and Orange.

• E.g. supports Microsoft MSN‘s mobile services (Hotmail and Messenger overSMS) in Europe.

Extension: Interface to extract core network data

JAVA API• Complete function set to extract core

network data

• Abstraction of SS7 network complexity

• Load balancing & failover

• High performance

ASCII based TCP protocol• Easy to use

• Synchronous and asynchronous communication

• Abstraction of SS7 network complexity

• High performance

Direct Application Interfaces


A) Presence Detection:- Provides the current status of a wireless device

(online or offline) for presence.

B) Location information:- Extracts the Mobile Switching Center Address for

roaming information.

C) Alert-Service Center

D) AnyTimeInterrogation (ATI)- AnyTimeInterrogation (ATI) to retrieve location

information about the subscriber.

E) Number Portability:- Identifies the international Mobile Subscriber Identity

(IMSI) for number portability.

Extension: Corenetwork data extraction.

Functionality Modular Framework


• With the A-SMSC solution, an application can request the status submission of a wireless user. The outcome of the delivery (successful or not) will be reported back to the application.

• Application Providers

- Detect if a user is online or not and deliver real-time short messages.

• Operators

- Direct delivery of short messages.

• Online Presence Detection enhances many applications requiring knowledge about the online status of the wireless user. Application

HLR/MSC

A) Presence Detection.

Status of a wireless user


• Operator can request HLR information using a simple IP based protocol. The MSISDN is used as the variable whereas the platform queries the HLR of the mobile user and returns:

- MSC Address.

- HLR Address.

- IMSI.

• Through the MSC address the operator knows the current (roaming) network of the wireless user.

• Through the HLR address, the operator knows which network the user has a subscription.

• Supports MAP commands:

- Send-Routing-Info-For-Location-Services.

- Provide-Subscriber-Location

B) Location Information.

Queries for an MSISDN, receive information from HLR


• The A-SMSC solution allows applications to request a notification if the user is online.

- The application requests an alarm trap by supplying the MSISDN to the platform.

- The platform sets the alarm request in the appropriate HLR.

- As soon as the HLR is notified about the online status of the user it notifies the platform.

- The platform transforms the SS7 alarm to IP and forwards it to the initiating application.

• As soon as the mobile user switches on their phone or has connectivity again, the application gets an alert and can start the dialogue.

• AnyTimeInterrogation can be used in MAP2+/3 compliant networks to request information about a wireless user.

• The information includes:

- Cell-ID.

- Current Status.

- etc.

• The information can be matched with databases to e.g. return the geographical coordinates of the wireless user and forming a cost efficient Location Based System (LBS) for applications.

• Key Benefits


Key Advantages of the A-SMSC.

Independent and flexible software and hardware architecture, open for future enhancements with clear interfaces.

Improves flexibility and performance in SMS delivery, enhanced routing possibilities and SMS handling to reduce messaging costs.

Range of innovative add-on functionality such as P2P direct delivery.

Benchmarked at high throughput levels.

Powerful, easy-to-use system maintenance services based on a web-interface as well as health checking and trouble-shooting tools, reducing operational costs and manual efforts.

Successfully implemented MO/AO and MT/AT direct delivery messaging to many Tier 1 and 2 operators, including Vodafone UK, O2, Orange, Hutchison and Cingular.

A-SMSC termination success rate proven to be higher than legacy SMSCs because of more sophisticated retry schemes (e.g. configurable based on MAP error code).
