Abstract: An apparatus, method and system for receiving an input indicating a mode into which to set a user equipment (UE) and at least one further UE associated with the UE, determining whether a connection circuit switched (CS) connectivity or packet switched (PS) connectivity and when the connection is the CS connectivity, generating a short messaging service (SMS) message that indicates the mode corresponding to the input. Also, receiving connectivity information for a plurality of UEs from a cloud network component, the UEs being associated with one another, the connectivity being CS connectivity or PS connectivity, receiving a response indication corresponding to a response performed on an incoming call by a first one of the UEs, the first UE having a PS connectivity, matching the response indication to a corresponding cause code and transmitting the corresponding cause code to a second one of the UEs having a CS connectivity.

Abstract: A user equipment (UE) is configured with a carrier aggregation (CA) functionality and UE connected to a network via a base station that serves as a primary serving cell (PCell) providing a primary component carrier (PCC) to the UE. The UE determines a plurality of bands that are supported by the UE for use in the CA functionality, generates an individual band information element (IE) including band information for the bands, determines at least one representative CA combination having an order, the order indicating a total number of component carriers (CCs), the at least one representative CA combination forming a basis to extrapolate a plurality of CA combinations having the order based on the band information, generates a representative CA combination IE including the at least one representative CA combination and transmits the individual band IE and the representative CA combination IE to the base station.

Abstract: A user equipment (UE) has a cellular connection established by a cellular chip, the cellular connection including a secondary component carrier (SCC) of carrier aggregation (CA) in the unlicensed spectrum. The UE receives, by a WiFi chip of the UE, a message from the cellular chip indicating a first frequency band corresponding to the SCC, determines whether a hotspot service is enabled utilizing at least a portion of the first frequency band that the cellular chip has indicated corresponds to the SCC and when the hotspot service is enabled, switches, by the WiFi chip, the hotspot service from the first frequency band to a second frequency band.
