This 5G case uses parallel CU-DU information exchange to reduce total interaction time across multiple distributed units.

This case uses idle or inactive-state UE measurement and preconfigured DC/CA settings to shorten connected-mode transition time.

This case restricts NR resource sets for certain UEs, balancing 5G access with 4G/LTE capacity and congestion control.

Separate S1a-C and S1a-U paths link TWAN with the MME and SGW, reducing signaling, latency, and inter-system handover interruptions.

During random access, base stations combine control and downlink data signals to accelerate synchronization and reduce transmission delay.

Randomly selected links and coded packets adapt multi-link transmission to changing conditions, improving throughput and reliability.

This case routes selected uplink data through an additional PGW-U, preserving PDN connections while supporting lower-latency services.

During inter-system handover, source identity signaling avoids unnecessary packet forwarding and preserves data continuity.

Paging overlap coordination helps multi-USIM devices avoid missed pages.

This case uses validated capability IDs shared across UEs to limit air-interface signaling and streamline network capability storage.

This case removes transaction IDs from selected RRC mobility messages to reduce inconsistencies during PCell and PSCell changes.

The apparatus uses millimeter-wave and lower-frequency links to balance high throughput with more stable communication.

Maintain MBS continuity in idle states using random access and prepared configuration.

PMIP-mediated trust checks secure relay WTRUs without complex device-side verification.

When a PCF becomes unavailable, the NRF transfers active-session data to a standby PCF that rebuilds sessions and takes over.

Pre-established PCRF/PCF links and failure notifications reduce session setup delays by enabling seamless continuation after link failure.

This case aligns CSI feedback, DRX cycles, and SRS timing with non-integer NR traffic to improve UE power and resource efficiency.

This case assigns dedicated logical channels to active SIM profiles, enabling parallel communication while routing commands without collisions.

UEs signal available location references over sidelinks, supporting positioning in partial or out-of-coverage scenarios.

Registration feedback lets a 5G UE release connections or start a timer when pending uplink services are unsupported, conserving power.

After radio link or handover failure, terminals use available relays or suitable cells to resume RRC service faster.

A logical DetNet node combines a terminal and radio access network to deliver replication, elimination, and ordering over 5G.

This case coordinates existing and newly allocated SRB configurations across CU and DU for reliable RRC state resumption.

This case shows how UE timer-expiration handling selects alternative radio cells to preserve 5G emergency session establishment.

This case segments anchor and non-anchor carrier failures to simplify RLF handling and limit re-establishment delay.

This case shifts UE security key updates around the RRC resume request to shorten inactive-to-connected transition time.

The terminal records and reports idle-SIM disconnections, helping base stations separate normal events from network failures.

When a voice bearer may fail after handover, the UE assesses network conditions and triggers CSFB before rejection messaging.

This V2X case uses request and acceptance identifiers to establish one PC5 link per service and identify accepting UEs.

This case shows how a wearable switches from direct access to a relay terminal for reliable network access across complex scenarios.

This case uses hierarchical LTE, Wi-Fi, 3G, and 2G fallback networks when 5G NR IMS voice sessions fail.

This case uses existing DNS infrastructure to route users to edge management servers with more consistent service latency.

This case uses GTP-U path status signaling between network nodes to avoid failed bearers and maintain UE data connectivity.

When terminals move between UPF service areas, direct I-UPF routing to the proper anchor UPF reduces forwarding hops and delay.
