基于IP/MPLS的IP RAN解决方案

Radio Access Network Evolve to IP/MPLS

目前,全球的移动网络用户继续增长,语音流量仍不断攀升,然而随着HSPA等高速上网业务的大规模应用,数据应用流量带给移动网络巨大的带宽压力。与此同时,ARPU值并没有随着流量的增加而增长,每比特传输收入反而减少,因此运营商需要需求减少移动回程网络传输成本的方案。IP/MPLS采用先进的网络架构,融合了TDM和Ethernet/IP流量传送,很好的解决了这一问题,并完美支持向LTE演进。

Traffic levels continue to rise in mobile networks globally.Voice traffic continues to climb,but data applications,enabled by advances in the radio interface such as High Speed Packet Access（HSPA） in particular,are stressing the network.Additionally,average revenue per user（ARPU） is not keeping pace with these traffic increases,resulting in radical reductions in revenue per bit transported.Operators are tasked with lowering recurring costs in the Radio Access Network（RAN） .IP/MPLS brings to the modernized RAN architecture,support a combination of TDM and Ethernet/IP traffic and is scalable enough to support Long Term Evolution（LTE） .
