Solution Description

Teamup Technology's SIGTRAN Value-Added Services (VAS) Platform is built using a high performance and scalable software SIGTRAN protocol stack providing a suite of SS7-based signaling protocols over IP. It enables seamless convergence and inter-working of legacy circuit-switched networks and the next-generation IP networks. It is an essential component for building applications for all-IP networks.

The following describes two typical applications based on Teamup Technology's SIGTRAN VAS Platform:

Application Example 1: Number Portability
Teamup Technology has demonstrated the use of a SIGTRAN-based Service Control Point (SCP) for implementing operator number portability (ONP) and mobile number portability (MNP) services. The same platform can also be used to deliver advanced intelligent network (IN) services such as Personal Number and Centrex services, etc.

SSP: Service switching point SCP: Service control point DB: Database

Teamup Technology's SIGTRAN protocol stack implements both ITU-T Intelligent Network Application Part (INAP) Capability Set 1 (CS-1R) and Bellcore Advanced Intelligent Network (AIN 0.1) protocols. Cisco ITP carries an important role of bridging between the circuit-switched domain and the packet-switched domain. It connects to the legacy telco switches (SSP) through traditional E1 and/or T1 trunks, and the application servers (SCP) through SIGTRAN-based IP connections. When a call comes into a SSP, signaling information relating to the call will be routed via a SS7 signaling link in a E1 or T1 trunk to the ITP. The ITP forwards the signaling information to the SCP via SCTP. The SCP contains the decision logic for translating the calling and called party numbers for the incoming call. The translation results will be returned from the SCP to the SSP via ITP.

Application Example 2: Short Message Routing Gateway

Short Message Service (SMS) has proved to be one of the most successful data services and a key revenue generator for mobile network operators worldwide. The fast growing SMS traffic can seriously strain the capacity of SMS infrastructure and negatively impact the quality of service. Teamup Technology's SMS Routing Gateway is designed to eliminate SMS traffic bottlenecks through efficient load-sharing of SMS traffic among a number of SMSCs. The SMS Routing Gateway enables mobile network operators to optimize their network by setting up rules for distributing SMS traffic over different SMSCs based on origination and destination addresses. In this way, SMS network efficiency is maximized and SMS resources are optimized. It also improves the quality of service to customers and increases control over SMS traffic for mobile network operators.

SMSC: Short Message Service Centre SMPP: Short Message Peer-To-Peer Protocol MAP: Mobile Application Part

When a mobile subscriber initiates the sending of a SMS, the SMS arrives at the ingress through a SS7 Mobile Application Part (MAP) service primitive in the circuit-switched domain. The SMS is then forwarded via Cisco ITP to Teamup Technology's SIGTRAN-based SMS Routing Gateway through another MAP service primitive in the packet-switched domain. The SMS Routing Gateway selects an egress SMSC based on a number of criteria, including origination and destination addresses (OA/DA), type of number (TON) and numbering plan indicator (NPI). A web-based GUI user interface is provided to the mobile operator for defining their own routing rules. Bad lists can also be created to filter unwanted SMS. The SMS will then be forwarded to the selected egress SMSC via the Short Message Peer-To-Peer (SMPP) protocol.

Target Industry

Wireline and mobile network operators are evolving from their legacy circuit-switched networks to packet-switched networks. The migration to an underlying packet-switched transport network is essential for the convergence to an all-IP network with associated technologies and signaling protocols to support the delivery of multi-media services. The evolving network is combining telecom, the internet, messaging and various media services, and enabling more feature-rich applications.

Features & Benefits
Key features and benefits of Cisco ITP include:

• Infrastructure Cost Reduction
• Improved Scalability
• SCP ROI Efficiency Improvement
• Enable Revenue Generating IP-based Applications
• Integrated leading IP Routing, IP WAN media support, and QoS
• All-IP Investment Protection

Key features and benefits of Teamup Technology's SIGTRAN protocol stack include:

• Eliminates the 64 Kbps per signaling link restriction which applies to legacy SS7
• Runs on standard servers and requires no specialized hardware
• Cost-effective for building value-added multi-media applications for next generation networks
• Leverages the benefits of IP domain in terms of operation and maintenance
• Follows industry standards and allows customers to interoperate in a multi-vendor environment
• Cost savings and ease in technology upgrade without worrying about end-of-life (EOL) of SS7 hardware

System Components

During gradual migration to all-IP networks, telecommunication operators want to safeguard their investments in their legacy circuit-switched infrastructure and value-add services. Cisco IP Transfer Point (ITP) provides a seamless connection gateway between the circuit-switched domain and the IP/IMS domain. The Cisco IP Transfer Point (ITP) is a product for transporting Signaling System 7 (SS7) traffic over IP (SS7oIP) networks. The Cisco ITP product allows Mobile Operators to efficiently transport increasing volumes of SS7 traffic by offloading the traffic from the legacy STP network to an SS7oIP network. Cisco ITP also positions the Mobile Operator for enhanced ROI and profits by providing the infrastructure for IP-enabled Service Control Points (SCP) and revenue-generating IP services.

SIGTRAN is a family of protocols for providing reliable datagram service and user layer adaptations for SS7 protocols. It uses an IP transport called Stream Control Transmission Protocol (SCTP). SIGTRAN brings to packet networks all the proven and deployed qualities of the traditional SS7 networks which have existed for a long time and have gone through a lot of improvements over the years to meet high performance demands of switching and multi-media services.

Teamup Technology's SIGTRAN is a software protocol stack providing SS7-based signaling protocols over next-generation IP networks. Teamup Technology's high-performance SIGTRAN protocol stack runs on RedHat Linux operating system and has demonstrated to support thousands of TCAP transactions (query and response) per second.
