Abstract: A method is disclosed to help register a UE with a different network in the event of an unsuccessful registration with a fallback network. In accordance with the disclosure, a UE may be registered on a first network and may then seek to register with a second network via the first network. The first network may attempt to register the UE with the second network, but the attempt to register the UE with the second network may ultimately fail. In response to such failure, the first network may discontinue providing service to the UE. Discontinuing the providing of service to the UE on the first network may result in the UE seeking to register directly with the second network or with a different network. By registering directly with the second network, or a different network, the UE may be able to initiate and/or receive voice calls via that network.

Abstract: Disclosed is a method and system for compensating for excessive attenuation on an RF connection between a remote radio head (RRH) and an antenna of cell site. In an example configuration, in which first and second RF carriers of a cell site traverse different RF paths between respective RRHs and respective antenna, the second RF carrier may be subject to more attenuation than the first. Consequently, antenna transmission power of the second RF carrier may be below one or another threshold. For communication services to user equipment devices that involve both the first and second RF carriers, the diminished antenna transmission power of the second RF carrier may cause service degradation. In accordance with example embodiments, a controlling network entity may determine that the power is diminished, and responsively reallocate transmission power from an underutilized carrier to the second carrier, thereby boosting its transmission power and remediating service degradation.
