TeleQuill SBC of Alpha Bridge

PRODUCT DESCRIPTION

The rapid adoption of IP for many voice and multimedia communications needs of enterprises, consumers, and service providers has resulted in a never-broadening array of IP networks, Customers increasingly expect secure, transparent access and utilization of these advanced networks bringing issues like security, interoperability, protocols, vendor implementations, system complexity, and service assurance are arising for network operators, and in turn they are demanding carrier grade intelligent session border controllers (SBCs) to ensure a seamless communications experience.

The Telequill SBC is a Intelligent Session Border Controller for fixed, mobile, cable, and Over-the-Top operators and enterprises. Deployed worldwide and operating in some of the world’s largest IP networks, the SBC provides industry-leading security, session management, policy control, and deployment flexibility to enable seamless SIP Trunking, Peering, Intra-Network Interconnect, Multimedia Communication and RCS solutions in IMS VoLTE/VoNRand Fix-Line networks.

Alpha Bridge Technologies Telequill SBC is convergence SBC with the following function support:

  • A-SBC

Telequill SBC Typical Application Scenario

VoIP Service Router/Firewall between Different Networks

IP networks of different areas may not have direct interconnectivity, such as a corporate intranet and the Internet, or the Internet and an NGN operating platform network. SBC can work as a bridge and perform VoIP service routing between these independent networks.

High Availability

SBC supports HA function:

  • Two SBCs provide services to the outside world through the two planes that constitute the active and standby links.
  • Under normal circumstances, The host is responsible for the business and backs up the business to the standby machine, the backup machine does not provide business but accept business backup.
  • When the host fails, the backup machine takes over the external service, thereby automatically ensuring that the system can continuously provide the service without manual intervention.

Core Pool and Dual Attribution

  • Dual attribution is a special case of pool.
  • After the main CORE fails, SBC automatically switch to other CORE

  The SBC can be rewound if the original CORE is restored

ATCF/ATGW in eSRVCC solution

1.After receiving the message, the eMSC will perform route addressing analysis through the STN-SR (ATCF), and find the route to the ATCF node that allocates the STN-SR.

2.The eMSC send the INVITE message to the corresponding ATCF. It carries the STN-SR (ATCF) and C-MSISDN obtained from the MME. (The PSI route may be addressed to the ATCF through the I-CSCF, or the ATCF IP may be obtained directly by the DNS resolution. The specific implementation is determined by the routing strategy of different operators.)

3.After receiving the INVITE message from the eMSC, the ATCF determines whether the STN-SR is equal to the STN-SR predefined by the node. If they are equal, the SRVCC process is continued, and the ATGW is notified to perform corresponding bearer switching according to the user session in which the C-MSISDN is carried that needs to perform handover.

 

The main handover process steps are described as below:

1.When the MME detects that the LTE signal weakening needs to be handed over to the CS domain to ensure call continuity, the MME initiates an SRVCC handover procedure to the associated eMSC through the SRVCC PS to CS request message. It carries the updated STN-SR (ATCF) and the C-MSISDN used to associate users.
