AI Technical Summary

Problems solved by technology

The problem with these two existing techniques is that each time the SGSN receives an instance of downlink data (e.g. N-PDU) for each individual wireless device, the SGSN needs to perform these procedures, which may result in High signaling load on the Gb interface between
