Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, while operating in an out-of-service (OOS) mode associated with a first network, that a second network satisfies one or more switching criteria. The UE may increase a time duration associated with a periodic network acquisition scan associated with the first network based at least in part on detecting that the second network satisfies the one or more switching criteria. The UE may switch, while operating in the OOS mode, from using the first network for connectivity to using the second network for connectivity based at least in part on detecting that the second network satisfies the one or more switching criteria. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may disconnect from a first radio access technology (RAT) service, independent of signaling from the first RAT service, after sensing that the UE has entered a coverage hole. The UE may use a connection to a second RAT service while in the coverage hole in association with disconnecting from the first RAT service. The UE may disconnect from the second RAT service, independent of signaling from the second RAT service, after sensing that the UE has exited the coverage hole and before expiration of a radio link failure (RLF) timer for the second RAT service. The UE may reconnect to the first RAT service before expiration of an RLF timer for the first RAT service. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, while camped on a cell of a first radio access technology (RAT), a search for closed access group (CAG) cells of a second RAT different from the first RAT. The UE may populate a database based at least in part on the search, wherein populating the database includes associating the cell of the first RAT with one or more of the CAG cells of the second RAT. The UE may perform a reselection process from the cell of the first RAT to a first CAG cell of the second RAT, of the one or more CAG cells of the second RAT. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use the techniques described herein to reattempt a video telephony (VT) call after receiving a rejection message indicating that a prior attempt at the VT call failed. In some cases, the UE may have a first configuration indicating that the UE is to redial VT calls exclusively using packet-switched (PS) networks. In other cases, the UE may have a second configuration indicating that the UE is to switch to a circuit-switched (CS) network after one or more failed attempts at the VT call using PS networks. In any case, once the UE receives a rejection message in response to a prior attempt at a VT call, the UE may reattempt the VT call based on a rejection cause in the rejection message and whether the UE has the first configuration or the second configuration.
