Abstract: A method and apparatus may receive policy information from a network. The policy information indicates at least one preferred radio-access-technology for a service. The method may also include entering a coverage area of the at least one preferred radio-access-technology. The method may also include detecting that the service corresponding to the at least one preferred radio-access-technology is offered in the coverage area. The method may also include initiating a request for setup of the detected service.

Abstract: A method and apparatus are provided. The method includes providing a primary secondary cell by a second node for a user equipment operating in dual connectivity with a first node and the second node; and receiving a request from the user equipment requesting that the primary secondary cell provide the functionality of a primary cell for the user equipment when a radio link between the user equipment and a primary cell provided by the first node is lost.

Abstract: Systems, methods, apparatuses, and computer program products for security handling in, for example, cells that support multiple frequency band indication are provided. One method includes receiving, for example by a source evolved node B (eNB) configured to communicate with a user equipment, a multiple frequency band indicator (MFBI) list, the multiple frequency band indicator (MFBI) list comprising at least one frequency band number listed in the same order of priority as broadcast by a target eNB. The method may further include selecting one of the at least one frequency band number for use by the source eNB, calculating a security key (KeNB*) using the DL EARFCN belonging to the selected frequency band number with the highest priority that is also supported by the user equipment, and signaling the calculated security key to the target eNB.
