Abstract: A method and corresponding system for configuring an eNodeB for improved circuit-switched-fallback (CSFB) service. The method includes detecting that, during past CSFB call setup for UEs served by the eNodeB, UEs reported as a strongest fallback coverage area a fallback coverage area that is not included in the eNodeB's CSFB-candidate data. And the method includes responsively (i) determining, based on location information and based on an identifier of the reported fallback coverage area, a node of the fallback network that the eNodeB's network can contact to facilitate CSFB call setup in the reported fallback coverage area, and (ii) adding to the CSFB-candidate data a record of the reported coverage area in association with a node identifier of the determined node, the added record being thereafter useable by the eNodeB to facilitate CSFB call setup in the reported fallback coverage area for a UE served by the eNodeB.

Abstract: A method and system to help manage air interface resources for communication between a user equipment device (UE) and a base station. As disclosed, a UE or base station detect a situation where a transport block that the base station would allocate to the UE would be too small to hold carry a packet that the UE would seek to transmit, and the UE and base station responsively switch to a mode of operation in which the UE will receive a multi-TTI transport block allocation rather than a single-TTI transport block allocation. Given a per-TTI limitation of available air interface resources, the allocation of a transport block spanning multiple TTIs may thus provide the UE with increased air interface capacity for transmission, thus optimally allowing the UE to transmit without a need for segmentation.
