How Softswitch technology promotes network convergence

The Softswitch technology is still quite common, So I studied how the Softswitch technology promotes network convergence. Here I will share it with you and hope it will be useful to you. The network built by Softswitch technology is a business-driven network. It achieves a relatively independent business system through business/call control separation and call control/bearer separation, so that the business is independent of the network.

The Softswitch technology is the development trend of the network. The Softswitch layered architecture will gradually become the mainstream architecture of the core network circuit domain ~ Gradually eliminated within 10 years. Compared with non-layered networks, Networks Based on Softswitch have obvious advantages, the two most important drivers of layered architecture are economic-driven and future-oriented open business architecture, which can continuously meet users' business needs, enhance the overall competitiveness of the Operation Network to achieve sustainable development.

Advantages of softswitch in network construction

The Softswitch technology can promote business convergence and network convergence, and can uniformly allocate a variety of business resources to achieve full-network business development, the business growth driven by such business integration and openness far exceeded 1 + 1 ...... This model brings profit for the operator's sustainable development. At the same time, business integration and innovation also promote network development. The development of Softswitch technology can promote centralized network management, take into account the development of current network services through the construction of GSM Softswitch, and promote the establishment of a new network maintenance system, from the management point of view to the next generation network evolution. It can be provincial-centered, integrate provincial maintenance manpower, and integrate the maintenance talents of different regions and networks to form a sound internal competition environment, improve network maintenance quality, speed up maintenance response, and reduce maintenance investment.

Through the flat Networking capability of softswitch, the multi-level convergence of the current network is simplified, making the network data configuration easier and reducing the difficulty of engineering maintenance. The Softswitch device also features large capacity and high integration. It can replace multiple old devices with small capacity on the current network to achieve resource integration and improve network quality. The Softswitch feature optimizes network resources and topology to enhance the network's anti-Traffic Impact capability. Therefore, Softswitch technology has become a trend in network development. The use of Softswitch technology to optimize and upgrade 2G networks. What are the benefits of the network compared with the traditional model? The following is an analysis from three perspectives:

The introduction of softswitch can optimize the network structure

In the traditional mode, the configuration and management of switch data is very complex. The configuration of traffic routes and Signaling routes is directly proportional to the number of switches, making it difficult to adjust and expand the network, the IP end-to-end addressing capability enables the core exchange network to have flat networking capabilities and greatly simplifies the network topology. It is clear that the connection method of the network element is gradually transitioned from the mesh network to the star network and eventually reaches the IP network.

The introduction of softswitch can reduce maintenance costs

In the traditional mode, the maintenance is point-to-point, that is, the number of MSC requires multiple maintenance points, the maintenance power is relatively scattered, and the investment is large. In the softswitch mode, the maintenance of the softswitch core network can be set according to the system of the region. The maintenance power is more concentrated, which is conducive to centralized management and maintenance, and the maintenance cost is greatly reduced. Therefore, the Softswitch technology can reduce maintenance investment in the form of networking.

The introduction of softswitch allows you to quickly develop special services

In the traditional mode, each terminal or independent SSP upgrade is required to carry out a business, and the Business loading needs to be loaded on the network elements of all terminals, this method is not only restricted by business development, but also complicated for business loading. In the softswitch network mode, the service upgrade is only related to the MSC Server. That is to say, although multiple mgws may need to be placed as the service access, the business control is completed by the MSC Server, only the Server is involved in service upgrade, and the service load is easy.

Softswitch separates services from control, and calls control and bearer. It facilitates the development of a variety of special services and enhances the capability of providing network services, this is also an important aspect of business-driven network transformation. Therefore, the optimization of the Softswitch technology for the network is not only to save the current network investment, but also to bring revenue growth points to the network.

For a 2G core network, mature Softswitch technology can be used to build GSM, which can combine Network Construction with long-term investment, and use advanced technologies to enhance the capability of the GSM network, implement investment protection for GSM networks before 3G construction to reduce CAPX for the entire network and reduce OPEX for the entire network through centralized management of O & M.

Network construction mode of Softswitch

Next, we will discuss several network modes using Softswitch technology.

Big network Networking Solution

In the big network mode, multiple branch networks can be divided. The maintenance of multiple branch networks can adopt centralized maintenance or decentralized maintenance. When the Softswitch technology is used to provide a large network solution, one msc server and multiple mgws are used to achieve traffic absorption across different small networks. An MGW is placed in each region, centralized O & M management is implemented in the central area Bureau. The big network solution is very suitable for reorganizing multiple small networks, reducing O & M costs and investment in network construction. Compared with the traditional network mode, the big lightning network has obvious advantages. Specifically, the system only needs to build a MSC to solve the cross-region coverage problem if it can absorb multiple small lightning networks, centralized O & M management.

It can effectively achieve nearby access across regions, solve the problem of loose routing of traditional vswitches in large networks, and save transmission resources. It can completely solve the problem of cross-region billing for the same bureau. Using the terminal Bureau's big data network solution can solve the data center relocation problem, and pull the MGW to the new data center for device relocation. The data configuration is basically concentrated on the msc server side, reducing the difficulty of Data configuration on the MGW side.

Intra-board A-Flex technology

Intra-Bureau A-Flex technology can balance the current GSM traffic and share resources between devices. In-board A-Flex technology refers to the connection between a bsc and two mgws in the board to make full use of MGW resources. In the traditional switch network mode, a BSC can only be connected to one MSC. Therefore, when a BSC is connected to MSC, traffic congestion cannot be diverted to other MSC services, the call may be blocked or even paralyzed, and the-Flex technology in the board can be used to connect the BSC to two mgws without the need to upgrade the current network BSC. The two mgws can be dynamically adjusted, ensure the connection quality of the network.

Provides a variety of disaster recovery methods to ensure Network Security

Using Dual-attribution technology, MGW can be connected to two MSC servers at the same time for Server-level N + 1 backup. Advanced IP technology and device separation architecture ensure that local backup is added at the signaling control layer.
