Comparison between IP RAN(IP/MPLS)and PTN Solution (1) Item PTN IP RAN Comments (IP/MPLS) The cost of ATN and PTN is almost same. Cost 1. Huawei IP RAN (Based on IP/MPLS )solution has an ability for easy expansion with automatically IP routing protocol, when new ATN (access router) added in the network, just Easy Expansion need few modification on the ATN box like IP address etc. 2. Using Huawei NMS U2000 GUI to configure the IP Backhaul ATN routers in batch remotely. With Huawei NMS U2000 GUI based on rich IP/MPLS features, management is centralized ,troubleshooting is highly efficient with integrated expert analysis system and demarcation function is so easy for maintain team to distinguish responsibility for poor quality Easy M&O issue in different segment network. Huawei router has built-in IPFPM/Y.1731/MPLS-TP OAM/BFD features, which can measure the network KPI anytime and fast locate failure point within few minutes. With the function of DCN (Data communication Network) communicating by the ATN itself after power on, we can remotely configure big amount ATN routers in batch with NMS, no need any Fast Implementation configuration on site, fast implementation. HUAWEI TECHNOLOGIES CO., LTD. Page 1 MPLS-TP network is a closed network. lower delay and at lest 5% bandwidth resource can be saved. Page 2 . PTN can’t support this feature. Open architecture Huawei router (Based on IP/MPLS) interoperability has been proven by famous 3rd party organizations and many Tier One operators. X2 traffic can be forwarded as near as LTE ready possible. LTD. HUAWEI TECHNOLOGIES CO.. The interoperability of MPLS-TP (PTN use) equipment is so limited.Comparison between IP RAN(IP/MPLS) and PTN Solution (2) Item PTN IP RAN Comments (IP/MPLS) • X2 traffic needs end to end delay less than 10ms. • e-MBMS service needs IP multicast to realize P2MP between e-MBMS gateway and eNBs. • eNodeB Re-homing frequently when expansion happen. which bring more delay. IP RAN(based on IP/MPLS): The gate way of eNB is ATN. IP RAN solution need not manually configure. PTN use MPLS-TP protocol: X2 traffic will go through aggregation nodes.

Reason2: Re-Parenting/Re-homing Needs L3 to Edge eNodeB Re-Parenting frequently Multi-layer coverage helps increasing the EPC1 EPC2 capacity of radio network But it causes cell splitting.
