Connection Management TRIZ Cases

Explicit UE release requests and resource validity terms help base stations reclaim unused D2D radio resources without continuous monitoring.

A UE reports available DRB-IP capacity before PDU session setup so 5G security policy matches processing limits and avoids session rejection.

A relay accessory bridges push-to-talk terminals on different networks, translating protocols and audio without modifying existing terminals.

Independent identity federation authenticates UE attach requests, then exposes available MEC resources at the wireless edge to reduce cloud latency.

Preconfigured dynamic cell sets use advance L3 measurements and candidate cell links to cut frequent handovers, signaling overhead, and delay.

Stored connection metrics let the network reuse UE settings during dual-connectivity reconnection, cutting delay, measurements, and misconfiguration risk.

When a main SMF fails, a backup SMF uses batch PFCP session migration so the UPF preserves session continuity with lower message overhead.

Aligning DRX on-durations with posSIB transmission windows cuts UE power use while preserving timely positioning data reception.

Preconfigured source and target node recovery lets a terminal quickly re-establish links after conditional handover failure and reduce interruptions.

Conditional handover preconfigures the target RAT and core compatibility to preserve UE context, security keys, and user plane continuity.

Distinct PTM and PTP logical channel configurations let UE map LCIDs and RLC bearers per TMGI, improving NR multicast scheduling efficiency.

A virtual assistant detects emergency context, suppresses risky audio, and sends silent situational data to responders.

Measurement filters let the UE send only relevant log results, cutting wireless traffic, message delay, and network-side data handling.

Before a multi-card UE leaves one network, a leave notification lets the network stop service processing and avoid resource waste and bad statistics.

Preconfigured uplink shared channel resources let a UE skip random access during RRC resume, cutting delay, power use, and abnormal network states.

When radio link failure disrupts sidelink relay communication, switching to a secondary relay restores coverage and transmission reliability.

Pre-established path identifiers let network elements reuse overlapping PDU session paths, cutting signaling overhead and handover switching delay.

By releasing unoccupied SL process associations and clearing buffers after MAC reset, this case preserves sidelink availability and receiving reliability.

A Layer 2 uplink grant lets the UE accept, delay, or reject DRX entry, reducing involuntary latency while preserving power savings.

Classifying UEs as stationary or mobile lets the network switch between SMSL and SISO uplink modes to balance throughput and battery life.

During handover, the central unit passes sidelink information to the target node to preserve configuration continuity across cells and RATs.

Grouped NR sidelink DRX cycles, timers, and wake-up signaling cut UE battery drain while preserving sidelink reception and resource allocation.

Specific TEID bit marking lets the PGW recognize emergency bearers and suppress deletion when TEIDs are reused in cellular networks.

Nearby devices supply identity data after image capture, enabling smartphone photo tagging with lower memory and processing demands.

When repeated 5G RACH or radio link failures occur in NSA mode, the UE drops the weak 5G RAN to save power while keeping 4G connectivity.

Cross-layer bearer suspension and resume cuts signaling overhead and latency during MR-MC bearer type changes while protecting throughput.

SNN-based authentication vectors let relay UEs securely support proximity services when a second device is out of network coverage.

A connected SIM triggers peer SIM measurements and reports shared results to the base station, cutting multi-SIM handover delay.

A WLAN coordinates CBRS grants and interference checks so nearby mobile devices can form sidelinks without harming other spectrum users.

Buffering bearer procedure messages at the PGW during S1 handover with SGW relocation cuts unnecessary GTPC signaling and retries.

A second UE timer enables earlier SCG radio link failure detection and faster recovery, reducing service interruption in dual connectivity.

Automated SDN checks match new users to expected endpoints, verify edge reachability, and catch routing changes without manual testing.

Preconfigured beam patterns and paging preambles let idle user equipment report weak multicast reception and trigger beam updates with less signaling.

Feedback on wake-up indication aligns sidelink terminal states with DRX timing, improving transmission reliability while reducing energy use.

Broadcast relay-capability data in the first UE request to find U2U relays with less signaling overhead and cleaner target UE updates.

Pre-configured UE buffer rules prioritize and expire QoE data in RRC idle or inactive modes to cut reporting delay and signaling overhead.
