Abstract: In a wireless communication core network, an Application Function (AF) make an analysis request for a mobility analytics report of a UE, which includes first UE mobility information of the UE. In the wireless communication core network, a Network Data Analysis Function (NWDAF) obtains an identity of an Access and Mobility Management Function (AMF) serving the UE from a Unified Data Management (UDM), on its own or via a Network Exposure Function (NEF), based on the request. Then, the NWDAF obtains second UE mobility information of the UE from the AMF according to the identity of the AMF, and generates and transmits the mobility analytics report to the AF according to the first and second UE mobility information.

Abstract: A base station (BS) and data transmission method thereof for mobile communication system thereof are provided. The BS transmits an ultra-reliable transmission parameter of a user equipment (UE) to a core network to make a user plane function (UPF) of the core network establish a first protocol data unit (PDU) session with the UE via the BS. The BS selects a secondary BS and transmits UE information to the secondary BS over a communication interface. The BS transmits a BS selection message to the UE to make the UE connect to the secondary BS. The BS transmits the BS selection message to the core network to make another UPF of the core network establish a second PDU session with the UE via the secondary BS.

Abstract: A method for relocating control plane management node of a user equipment includes: a first control plane management node coupled with a base station requesting from a second control plane management node for its connection information; and without releasing network connection of the user equipment, the first control plane management node commanding a user equipment coupled with the base station to update its connection information, so that a second control plane management node manages control plane of the user equipment instead of the first control plane management node.

Abstract: A wireless communication system includes a broadcast/multicast service center, a first multimedia broadcast/multicast service (MBMS) subsystem and a second MBMS subsystem. The first MBMS subsystem includes a first MBMS core network coupled with the broadcast/multicast service center and a first base station coupled with the first MBMS core network. The second MBMS subsystem includes a second MBMS core network coupled with the broadcast/multicast service center and a second base station coupled with the second MBMS core network. The broadcast/multicast service center redirects MBMS data of a content provider which is transmitted from the broadcast/multicast service center to the first base station via the first MBMS core network to the second MBMS subsystem and the second MBMS subsystem forwards the MBMS data to the first base station, when the MBMS data is congested in the first MBMS subsystem.
