Based on dynamic IP/MPLS, an IP RAN network is built with packet-switched routers that can provide high bandwidth, high reliability, low delay, low cost, full services, and E2E QoS. IPRAN has become a mainstream networking solution for mobile backhaul. It is used to carry not only mobile voice and broadband multiservice to meet the need for 2G, 3G, and LTE/LTE-A base station access but also carrier-class government and enterprise network services to satisfy operator needs for fixed mobile converged (FMC) full-service operation. Compared with traditional packet-switched networks, an IP RAN network introduces BFD, FRR, tunnel protection, and rapid route convergence technologies to ensure millisecond-level reliability, and meet the clock synchronization requirement of base stations and TDM traffic. The IP RAN network also simplifies service deployment through a graphical E2E network management system. This guarantees large-scale networking and reduces O&M costs.
Here are a few consideration when setting up IPRAN in Telcos:
1- Installing routers according to the locations requested by the customer, and making sure that they are all appropriately connected to each other and all neighbours are reaching out
2- Distribute the addresses according to the ip plan granted by the client to the routers accurately so that there is no conflict or waste, taking into account the addresses of management for remote access and the address of the router as the router ID
3 – Configure the routers with the agreed-upon approaches for use in terms of access protocols, including OSPF or ISIS, and others, where each router is linked to aggregation routers or core routers
4- Integration of the routers and entering them into the management so that the customer can access them through the private monitoring system
5- After making sure of the range of router packets and the values of the received and sent TX and RX and that there are no problems in accessing the core routers in more than one direction to ensure reliability, they can be loaded with the required communication services such as 2G, 3G, 4G
6- Following up on the level of services after uploading them to the routers, monitoring the quality of the connection, and troubleshooting in the event of any problem with that
The above was a small overview of the establishment of the access layer routers, which represent the first layer of the division of the IP RAN layers, which is the CSG (Cell Site Gateway) until it reaches the routers of the second layer of the division, which is the ASG (Aggregation Site Gateway).
