Nomor provides SAE (System Architecture Evolution) test bed within the SEA project

Date: 2009-06-30

To demo the benefits of the SEA adaptation framework especially in a mobile network, Nomor implemented a test bed, showing handovers between 3G networks (HSPA and LTE) and also non 3G networks (e.g. WiMAX). As the SEA content adaptation framework works with H.264 SVC (Scalable Video Codec), MVC (Multi View Codec) and MDC (Multi Description Codec) it is a good candidate to improve the perceived QoS for mobile clients especially in cases like handover, where network capabilities may decrease or increase suddenly. 

The Nomor testbed comprises a UE with software emulating the handover logic including the data router module. Handovers between 3G and non-3G networks are initiated by the UE performing the standardized attach / detach procedures manually or automatically, based on the signal strength or CQI. Also MME, PGW and SGW functionality are implemented. Protocols involved in the SAE based handover, namely PMIPv6, to connect non-3G network to the SAE network, GTP, NAS, S1-AP, RANAP are implemented according to the standard but only to the extend they are needed for the purpose of the testbed.

Additionally to the protocols needed to control and perform handover, Nomor implemented also the NAM module (network awareness module) that is part of the SEA adaptation framework and that reports information about the current network capabilities that are used to do a proper adaptation decision.

The testbed description (D6.1.1) can be found at: SAE homepage, to get further information or discuss how the Nomor mobility test bed or Nomor could help you to investigate mobility aspects get in contact with us.
