Abstract: The present disclosure describes apparatuses and techniques of adaptive PLMN management for varying network conditions. In some aspects, a PLMN manager of a user equipment (UE) searches, as part of a registration procedure, a data repository of PLMN information that includes a PLMN blocked from registration for a duration of time and determines that the PLMN is blocked due to a signal-related condition with a cell of the PLMN (e.g., weak signal). The PLMN manager then determines, during the duration of time, that the signal-related condition between the UE and the cell has improved. In response to the improvement, the PLMN manager unblocks the PLMN before expiration of the duration of time. By so doing, the UE may reattempt registration with the unblocked PLMN at least once before the duration of time expires, which may allow the UE to register more quickly and reestablish network services.

Abstract: A user equipment (UE) identifies, a minimum connection time for a first radio access network (RAN) and connects the UE to the first RAN for a first time and to a second RAN for a second time. The first time and the second time are based on the minimum connection time. The UE thereby ensures that the UE is connected to the first RAN for at least the minimum connection time.

Abstract: A User Equipment (UE) (102) supports a plurality of RF bands (132) associated with a plurality of country codes. The UE (102) reduces the entirety of the set of UE-supported RF bands (132) based on a current, physical location (115) of the UE (102), and the UE (102) advertises only the reduced set of UE-supported RF bands to a network or wireless communication system (100), e.g., for attachment purposes. For example, the UE (102) may reduce the entirety of the set of RF bands that it supports (132) based on a country code provided by a base station (105, 108) of a network (100) and the physical location (115) of the UE (102), thereby generating a reduced set of UE-supported RF bands. Subsequently, the UE (102) may advertise only the reduced set of RF bands supported by the UE (102), and refrain from advertising one or more RF bands excluded from the reduced set, e.g., by omitting any indication of the excluded RF bands from advertisements.

Abstract: Apparatus and methods related to acquiring service on mobile computing devices (MCDs) are provided. A method includes determining a decreasing sequence of scan ratios, each scan ratio indicating a proportion of time over which a MCD scans one or more frequencies to attempt connection with a wireless network during a disconnected time window. The method further includes determining a connected time window' when the MCD is connected to the wireless network. The method additionally includes determining a ping-pong rate for the MCD based at least on a duration of the connected time window. The method also includes selecting a scan ratio from the decreasing sequence of scan ratios based on the ping-pong rate. The method further includes scanning the one or more frequencies in accordance with the decreasing sequence of scan ratios and starting from the selected scan ratio to cause the MCD to attempt connection with the wireless network.

Abstract: Apparatus and methods related to acquiring service on mobile computing devices (MCDs) are provided. An MCD can determine whether the MCD is connected to a wireless network. After determining that the MCD is not connected to the wireless network, the MCD can determine a scanning context that includes a mobility attribute and/or a location attribute. Based on the scanning context, the MCD can determine frequencies associated with the wireless network and scanning rates for scanning the frequencies, where each frequency can be associated with a respective scanning rate. The MCD can scan one or more of the frequencies at one or more respective scanning rates for a signal that enables the MCD to attempt connection with the wireless network.

Abstract: A first user equipment (UE) that is initially coupled to a second UE and a base station enters an out-of-service (OOS) state upon losing its wireless connection to a service via the base station. The first UE attempts to reestablish the connection while sending OOS recovery parameters to the second UE. The second UE does not automatically scan for service if a signal strength of its connection to the first UE is above a predetermined threshold level. In response to losing its connection to the first UE or determining that the signal strength of its connection to the first UE is less than the predetermined threshold level, the second UE activates one or more corresponding modems and executes OOS recovery protocols based on the OOS recovery parameters received from the first UE to attempt to regain service.
