Wireless Network Protocols TRIZ Cases
- Terminal Device Retransmission Preparation for URLLC Delay Reduction
A terminal device determines retransmission preparation based on scheduling probability values to shorten processing time.
- Roaming Data Routing via Home Network IP Allocation
Home network operator controls roaming data routing by negotiating IP allocation during user registration to reduce latency and improve service quality.
- Session Identifier-Based Handover Between Packet and Circuit Switched Networks
Assigning unique session identifiers enables selective handover of individual sessions between packet switched and circuit switched networks.
- PDCP Status Report for LTE Handover Interruption
Target eNB receives PDCP status report to forward only missing RLC SDUs, avoiding user plane interruptions.
- Authentication Device Key Management for Communication Networks
An authentication device assigns unique identifiers to participants, enabling secure key management across multiple sessions.
