Ericsson and SoftBank Mobile are working together to further improve the user experience in congested network environments with new Mobility-based Policy. The demonstration connects mobility management and policy control to optimize radio resources and reduce signaling traffic.

According to Ericsson, it's new software feature, the Mobility-based Policy creates a direct connection between Ericsson SGSN-MME 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 signaling traffic in the network. This is especially important in highly congested user environments such as Tokyo busy-hours.

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).
