Abstract: A method and apparatus are provided for a handover (HO) by a Mobility Management Entity (MME). The method includes receiving, from an evolved Node B (eNB), a handover required message including information indicating whether the HO is for a circuit switched (CS) network or both a CS network and a packet switched (PS) network; splitting a voice bearer from another bearer based on the information; and transmitting a handover command message to the eNB.

Abstract: A handover method and apparatus for facilitating a handover of a user equipment to a femto cell in a wireless communication system supporting both the femto and macro cells. When a handover condition is detected, the user equipment acquires identity information of a target femto cell base station from system information transmitted by the target femto cell base station, decides whether to handover to the target femto cell base station, based on the identity information; and transmits a measurement report message including the identity information to a serving base station of the user equipment, when the handover is to be made.

Abstract: An electronic device is provided. The electronic device includes a touchscreen display; first communication circuitry to establish a short-range communication connection; second communication circuitry to establish a cellular communication connection; and a processor. The processor is adapted to establish, using the first communication circuitry, the short-range communication connection with a wearable device based at least in part on a graphical code being displayed on a display of the wearable device; based at least in part on a determination that an embedded subscription identity module (eSIM) profile is not installed on the wearable device, display, via the touchscreen display, a user interface (UI) to install the eSIM profile on the wearable device, the UI including one or more contract options associated with a cellular network service for the wearable device; receive, via the touchscreen display, a user input to select at least one contract option from the one or more contract options; and transmit, using the second communication circuitry, a service subscription request corresponding to the at least one contract option to a first server associated with the cellular network service, such that the eSIM profile corresponding to the at least one contract option is installed on the wearable device based at least in part on the service subscription request.

Abstract: A method and apparatus are provided for a handover (HO) in an evolved Node B (eNodeB). The method includes receiving a measurement report from a user equipment (UE); transmitting, to a mobility management entity (MME), a handover required message including information indicating whether the HO is for a circuit switched (CS) network or both a CS network and a packet switched (PS) network; and receiving, from the MME, a handover command message. The information is used, by the MME, to split a voice bearer from another bearer.
