Abstract: Embodiments of the disclosure provide a method, device and computer readable medium for centralized unit switch. According to embodiments of the present disclosure, the DU transmits identity information of a target CU/DU to the source CU for the CU switch. The target CU does not need to initiate context setup procedure to set up context for the terminal device. Thus, the switch is implemented with minimized signaling and interruption in the data connection and the switched is completed faster by avoiding the unnecessary F1 AP context setup.

Abstract: This invention relates to a method for Core Network (CN) controlled traffic transmission in a dual/multiple-connectivity system. The method comprises the following steps: receiving a request containing information about a status of dual/multiple connectivity from the radio access network node; determining and providing a policy on a usage of dual/multiple connectivity to the radio access network node. This invention also relates to a system of Core Network (CN) controlled traffic transmission for a dual/multiple-connectivity, an apparatus for Core Network (CN) controlled traffic transmission in a dual/multiple-connectivity system and a non-transitory computer-readable medium with executable instructions for executing the method.

Abstract: A method and apparatus can be configured to receive an indication for support for a broadcast service enhancement layer from a first network node. The method may also comprise transmitting the indication for support for the broadcast service enhancement layer to a second network node. The method may also comprise receiving a broadcast service session request message from the second network node. The broadcast service session request message may indicate that a broadcast service session is for a base layer or for the enhancement layer.

Abstract: Systems, methods, apparatuses, and computer program products for supporting local MBMS distribution are provided. One method includes receiving, by a broadcast multicast service center (BM-SC), an activate multimedia broadcast multicast service (MBMS) bearer request message to initiate an activate multimedia broadcast multicast service (MBMS) bearer request procedure. The activate MBMS bearer request message comprises at least one of information on local MBMS distribution received from a local MBMS entity (LME), or a destination area, or a destination area and an indication that preferred delivery is via local distribution. The method may further include determining whether local distribution path will be used based on at least one of information received in the activate MBMS bearer request message, or stored information about local MBMS entities.

Abstract: The present invention addresses apparatuses, methods and computer program product for enabling support of legacy user equipment and legacy network elements in small cell system for LTE and beyond systems. Each small cell uses a unique pair of Physical Cell Identifier and E-UTRAN Cell Global Identifier {PCI, ECGI} in the small cell system. In a handover preparation phase, when an enhanced eNB initiates the handover request procedure, the source eNB includes the pair of {PCI, ECGI} in the handover request message. Upon the reception of the {PCI, ECGI} from the handover request message, the associated eNB determines the target small cell based on the received pair of {PCI, ECGI}.
