Wireless Network Protocols TRIZ Cases
- IMS Call Continuity via Dynamic Routable Number Allocation
Dynamic routable number allocation via SIP messaging resolves handover bottlenecks between IP multimedia subsystems and circuit-switched cellular networks.
- WebRTC Session Establishment via Operator SIM Server Selection
A WebRTC session method uses subscriber module identifiers to automatically select operator servers for direct terminal communication.
- Access Terminal DAP Handoff via Feedback and Partial Initiation
Terminal feedback prevents race conditions during data attachment point handoff, ensuring accurate assignment.
- Layer 2 Adapter Selection Using Real-Time Metrics
A Layer 2 adapter selecting system calculates metrics to identify the optimal network interface for packet transmission.
- Mobile Node Handoff Route Optimization Bypassing Home Agents
Segmented control and data planes allow mobile nodes to establish direct bindings, reducing transmission delay while maintaining mobility support.
- Wireless Mesh Border Router Time Division Multiplexing
A border router uses time division multiplexing to forward packets between IEEE 802.15.4 and IEEE 802.11 networks via a shared transceiver.
- LMA MAG Restart Detection for PMIPv6 Binding Restoration
Local Mobility Anchor detects Mobility Access Gateway restart to maintain binding cache entries, triggering early re-attachment for idle user equipment.
- Fast Session Resumption via Datagram Injection in Dormant Apps
A notification process extracts datagram packets from push notifications and injects them into application communication stacks.
- IPv6 Mobile Handover Using Link Layer Notifications
Link layer notifications trigger immediate router advertisements, reducing handover latency and signaling overhead in IPv6 mobile systems.
- Diameter Prefix Authorization Server for IPv6 Network Control
Prefix Authorization server mediates IPv6 prefix delegation to enhance control over renumbering while reducing routing protocol traffic volume.
- IMS Handover Control for Seamless CS to PS Bearer Transfer
IP Multimedia Subsystem establishes packet switched bearers before releasing circuit switched connections, eliminating service interruptions during roaming.
- Foreign Agent Handoff Path Optimization via Multicast Registration
Home agent multicasts registration messages to foreign agents, bypassing reverse tunneling through home agents.
- Layer 3 Handoff via Parallel Information Flow
A layer 3 point of attachment receives handoff indicative information in parallel with layer 2 processing to facilitate proactive service transitions.
- Dynamic Home Agent Selection via Preferred Roaming List
Mobile stations dynamically select home agents using preferred roaming lists to optimize packet-data communication efficiency.
- RCS Authentication via IMS OAuth Grants
An IMS network issues OAuth authorization grants for Rich Communication Services applications.
- LTE Anchor Tunnel Switching via MME Coordination
MME coordinates user plane tunnel setup and deletion to resolve idle mode anchor mobility complexity.
- SPUD Recommendation Message Control via Operator Intermediary
A control entity intercepts SPUD protocol recommendation messages to calculate and send certified updates based on network conditions.
- Handover SFN Indication in Wireless Random Access
Embedding system frame numbers in random access responses eliminates handover delays caused by separate broadcast channel monitoring.
