LTE ready

• _{X2 traffic needs end to end delay less than 10ms.}

PTN use MPLS-TP protocol: X2 traffic will go through aggregation nodes, which bring more delay.

IP RAN(based on IP/MPLS): The gate way of eNB is ATN, X2 traffic can be forwarded as near as possible, lower delay and at lest 5% bandwidth resource can be saved.

• eNodeB Re-homing frequently when expansion happen, IP RAN solution need not manually configure.

• e-MBMS service needs IP multicast to realize P2MP between e-MBMS gateway and eNBs. PTN can’t support this feature.

Open architecture

The interoperability of MPLS-TP (PTN use) equipment is so limited. MPLS-TP network is a closed network.

Huawei router (Based on IP/MPLS) interoperability has been proven by famous 3rd_party

organizations and many Tier One operators.

Why Layer3 to Edge for LTE Services ?



X2 Traffics requires <10ms latency. Microwave latency is longer than fiber (normally 1ms for each hop)



Multi-layer coverage helps increasing the

capacity of radio network



But it causes cell splitting, which brings

frequent rehoming between base stations

and BSC/RNC.

Demarcation is for business, wholesale and mobile backhaul

applications, enabling a clear separation between the different

Intelligent Ethernet demarcation devices offer advanced

functionalities such as service and link OAM, end-to-end traffic

management starting at the service hand-off point, extensive fault
