The development of traditional voice services is gradually approaching the ceiling, and the boom in MBB will bring new revenue growth points for operators. However, the bearer network has gradually become the bottleneck for the continued development of MBB. The continuous growth and benign operation of MBB urgently need to solve the challenges faced by the bearer network.
MBB development faces three major gapsFrom the perspective of network architecture, wireless networks change from breadth coverage to deep coverage. Driven by the development of MBB services, air interface technology continues to evolve, the coverage radius of base stations continues to shrink, and the number of sites has increased dramatically. However, it is very difficult for many city operators to develop new sites, especially how to find transmission resources very flexibly within a radius of 20 to 30 meters, while also addressing bandwidth and clock synchronization issues. How to achieve low-cost site acquisition has become the first challenge for MBB.
The second gap comes from the problem of network duplication of investment brought about by the evolution of air interface technology. Traditional chimney networks, each business and even each system will deploy an end-to-end network from the bottom up. For example, for GSM, UMTS, and LTE, there are multiple interfaces of E1/T1, ATM, and Eth, and corresponding mobile backhaul technologies may include technologies such as microwave, SDH/PDH, PTN, and router. The advantage of this kind of chimney network is that the quality of the service is high; the disadvantage is that the smooth evolution of the network is difficult, and the ability to adapt to the service is poor, resulting in serious repeated investment and high long-term evolution cost.
The third gap comes from network operation and maintenance. With the development of MBB is the massive base station deployment, followed by exponential maintenance work. The traditional IP operation and maintenance mode is manually configured by the command line. The task is heavy and it is easy to make mistakes. Network failures require expert site location and it takes a long time to repair the fault. How to simplify the operation and maintenance work and reduce the operation and maintenance cost has become a concern of more and more operators.
IP RAN helps MBB to cross the bearer deployment gap 1. Any media collaboration to achieve low-cost multi-layer coverageFor massive base station deployment, only by fully utilizing various access media and integrating as many physical resources as possible can the base station acquisition cost of the network be effectively reduced. Copper cables, microwaves, or optical fibers may be used to support base station access. Their bandwidth characteristics and quality characteristics may vary, and they need to be comprehensively utilized according to the scenario. The IP RAN solution can integrate multiple access bearer technologies into one solution, providing multiple clock implementations, and the transmission bandwidth can reach Gbit level. The bandwidth pressure for hotspots can be solved by WiFi offload. Solve the problem of carrier site resource acquisition.
2, to achieve a deployment, support UMTS / HSPA / LTE seamless evolutionIn the GSM era, SDH is mainly used for bearer, and static configuration is naturally adopted. The bearer network in the UMTS era began to be IP-based. Due to the stable site, the route-based Backhaul can still be statically configured. With the rise of MBB, multi-layer coverage of mobile networks often requires base station plug-in expansion. In order to reduce network nodes and avoid complex manual link adjustment caused by capacity expansion, the aggregation layer should consider enabling dynamic routing capability, and intermediate transition nodes support at the same time. Static configuration and dynamic routing. LTE or even later LTE-A, only the aggregation layer supports dynamic routing, which causes the X2 traffic switching point to be too high. In the CoMP scenario, the bandwidth of the access layer is seriously wasted, and the strict delay requirement cannot be met. The dynamic routing capability needs further. Extend to the bearer access layer and localize X2 Traffic. The IP RAN solution ensures that the IP bearer network is enabled to be dynamically routed in real time by static configuration. In the process of mobile network evolution, the bearer network is invested once and evolves smoothly.
3. Visualization of IP operation and maintenance, helping operators to easily operate the IP bearer networkIP RAN supports IP visualization and operation and maintenance, and unified network management through end-to-end. One-stop, plug-and-play feature for site installation enables new power-up devices to automatically find, assign addresses, and remotely update, significantly reducing labor costs. Service provisioning only needs to be configured at both ends of the service channel, and a channel can be configured in a few minutes, and the service configuration time is shortened by more than 50%. IP network operation and maintenance support hop-by-hop fault location and delimitation, and adopt GUI to optimize user interface, which can provide multi-level IP network visualization capabilities such as physical connection topology, logical connection topology, and service connection topology, so that fault location can be clearly presented to users. In front of the problem, the fault location time is saved by more than 95%.
The consulting firm believes that MBB will become the main growth point for future operators' revenue. In the next five years, we will see 600 million new M2M users and 3 billion new MBB users. Under the stimulation of many innovative services and intelligent terminals, MBB network traffic will explode, and the mobile bearer network will become the bottleneck for the further development of MBB services. The process of bearer network IP will certainly accelerate. At present, AT&T, Verizon, BT, TO2 and many other operators have adopted IP RAN scheme to build MBB bearer network.
