Why ss7 over ip
The media gateway works as an interface between different media formats across public and data networks, and it also connects the public analog network to a network of data packets.

Khomp's Blog. The SS7 signaling system When you use the SS7 protocol, instead of having all the digital information related to the call competing for space with the information required for making connections, there is a specific channel for sending the signaling information, which is common in several calls. Facebook Twitter Linkedin. Phone :. Instead, it performs similarly to the M2PA protocol. However, a Signaling Gateway will enforce the maximum octet limit when connected to a SS7 network that does not support the transfer of larger information blocks to the destination.
The Signaling Gateway has a critical role in the integrated network and is often deployed in groups of two or more to ensure high availability.
The following figure and description show how SS7 messages are encapsulated and sent over an IP network to a host in another network. There are many reasons for transitioning to an SS7-over-IP network. The resulting network offers improved cost effectiveness, increased capacity that can be further scaled as needed, a high Quality of Service QoS including redundancy and security, and efficient deployment using existing equipment.
SS7-over-IP networks lower network capital and operational expenditures. Improvements in technology and reductions in cost found in the general computer industry can be applied readily in signaling applications. Replacing long-haul point-to-point SS7 links between network elements with IP connectivity can reduce recurring signaling transport costs and the need for dedicated TDM lines.
IP-based network monitoring and provisioning improve operation efficiencies. SS7-over-IP networks offer increased capacity. The bandwidth overall is greater, both due to inherent capacity and to dynamic bandwidth sharing. Because the network developers, planners, and installers are no longer tied to deploying fixed circuits for signaling, they have the flexibility to define the network as needs and demands change. Flexibility is key in adapting bandwidth on demand; re-dimensioning the SS7-over-IP network can be done completely through software.
With legacy SS7, users are limited to either 56 or 64 kbps links. There is also flexibility when adding capacity for new IP-based solutions and value-added services; future enhancements are more transparent.
Enabling a network with IP does not require expensive investments or costly upgrades for existing end nodes; it enables migration to packet-based architecture without adding new point codes or reconfiguring the network. For M2PA, there are no architectural changes.
When considering a transition, determine the type of change to make. Consider the advantages and disadvantages of a dedicated network versus a converged network. Does the equipment need to be phased out or will new equipment be added? Does the network require additional protection or supplier integration through diversity?
All these issues should be considered in the initial planning because of their significant impact on the overall network architecture. While a dedicated IP network offers inherent security and minimal routing, a converged network carrying both voice and data also will satisfy these needs at a lower cost, provided that the QoS attributes such as Round Trip Time RTT , Packet Loss, and Jitter are satisfied.
These attributes should always be given the highest priority on the IP network. When transitioning to an SS7-over-IP network, consider these strategies:. The issue is more than cost savings. SS7 Over IP.
