Ericsson and SoftBank demo mobility-based policy

Ericsson claims industry-first demonstration connects mobility management and policy control to optimise radio resources and reduce signalling traffic

Ericsson and SoftBank demo mobility-based policy

Ericsson and Japanese mobile operator SoftBank Mobile are working together to improve the user experience in congested network environments by implementing a new mobility-based policy.

Ericsson's new software feature, the mobility-based policy creates a direct connection between Ericsson SGSN-MME (serving GPRS support node-mobility management entity) and Ericsson service-aware policy controller.

This connection enables mobility management information from the SGSN-MME to go directly to the service-aware policy controller, while selected policy decisions from the service-aware policy controller can then go directly to the SGSN-MME.

By off-loading the gateway, mobility-based policy supports an enhanced, location-based mobile user experience while reducing signalling traffic in the network. This is especially important in highly congested user environments such as Tokyo busy-hours.

Network performance is becoming an increasingly important differentiator for mobile operators, so improvements such as this help the operator gain an advantage, according to Ericsson.

Mr. Yoichi Funabiki, director, mobile network planning division, core network department SoftBank Mobile, said: "To accommodate our subscribers and data traffic growth, it is critical to optimise our spectrum. By enabling us to dynamically allocate the best radio resources on a per-user, per-terminal basis, Ericsson mobility-based policy has the potential to increase our network flexibility while reducing signalling traffic network wide - this efficiency drives additional opportunities to improve both the user experience and network performance."

Jan Signell, head of region North East Asia, Ericsson, said: "Ericsson and SoftBank Mobile work together to consistently enhance the performance and user experience on their mobile network. With this demonstration of mobility-based policy, an innovative feature of Ericsson's evolved packet core, we continue to strengthen our strategic partnership with SoftBank Mobile."

SoftBank Mobile network includes both Ericsson LTE radio access network and evolved packet core. Ericsson was also selected by SoftBank Mobile to supply and integrate its end-to-end mobile network solution for voice over LTE (VoLTE).
