Huawei, a leading global information and communications technology (ICT) solutions provider, has completed a breakthrough multi-mode, LTE to GSM ANR (Automatic Neighbor Relations) IOT (Interoperability Test).

Based on 3GPP R9 standards, Huawei’s completed LTE to GSM ANR IOT, reduces manual configuration for neighbor relations by 90%, improve handover success rate, and reduces network management and optimization costs for operators.

Multi-mode ANR, which supports the automatic management and optimization of neighbor relations for networks featuring multiple modes and layers, is a key feature of Huawei’s SingleSON solution. In 2011, Huawei completed an earlier version of the LTE to UMTS multi-mode ANR IOT with Qualcomm. This more recent iteration enables LTE systems to automatically manage neighbor relations for GSM NCLs (Neighbor Cell List) and NRTs (Neighbor Relation Table), enhancing user mobility experience when moving from an LTE network to a GSM network.

Mobile broadband networks are being challenged by increasing data traffic, and the solution typically involves moving from single- to multi-mode complicated network architecture. As an operator's best business partner, Huawei launched the SingleSON solution to help carriers efficiently manage multi-mode and multi-layer networks to realize the self-planning, self-configuration and self maintenance of the network and reduce the cost of operations and maintenance.

More and more operators are deploying the SingleSON solution in their network to realize automatic operations and maintenance. In 2011, Huawei successfully launched the SingleSON ANR feature for commercial use on an LTE network in Cologne, Germany, which also saw the ANR feature’s first successfully launch on a commercial network anywhere in the world.
