Aspects of the subject disclosure may include, for example, obtaining, for a plurality of dual connectivity mobile communication devices that are in communication range of a first access point that uses a first radio access technology and a second access point that uses a second radio access technology, a plurality of network communication parameters, the first radio access technology being a different radio access technology than the second radio access technology; obtaining a list of a plurality of configurations, each configuration identifying one or more time slots in which the first radio access technology is to be used and one or more other time slots in which the second radio access technology is to be used; selecting, from the list, a respective configuration to apply to each of the plurality of dual connectivity mobile communication devices, a first configuration that is selected being selected based at least in part upon one or more first network communication parameters, a second configuration that is selected being selected based at least in part upon one or more second network communication parameters; facilitating first communications, via the first access point and the second access point, with a first dual connectivity mobile communication device according to the first configuration, which is changeable in real-time during the first communications; and facilitating second communications, via the first access point and the second access point, with a second dual connectivity mobile communication device according to the second configuration, which is changeable in real-time during the second communications. Other embodiments are disclosed.

Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a connectivity request originated by a user equipment towards a next generation core network may be processed by the next generation core network. The next generation core network may then provide the user equipment an indication of whether the next generation core network supports an inter-RAT handover between the next generation RAT and a legacy RAT.

Embodiments of this application provide a session management method, an interworking method between different systems, and a network apparatus. The session management method includes: when establishing a guaranteed bit rate (GBR) flow of a terminal device in a first communications system, determining, by a session management network element in the first communications system, that the GBR flow is a GBR flow required for handing over the terminal device from the first communications system to a second communications system; and establishing, by the session management network element for the GBR flow, a session context corresponding to the second communications system. The methods and the network apparatus are used to resolve a technical problem of resource waste existing in a handover method in the prior art.

Certain example embodiments provide systems, methods, apparatuses, and computer program products for a handover of a coordinated multi-point connection. For example, certain embodiment may transfer a first coordinated multi-point connection (e.g., a further enhanced multiple input multiple output (FeMIMO) connection) to a second coordinated multi-point connection where the network may instruct the UE to not perform at least one random access procedure. The first coordinated multi-point connection may be controlled by a first cell (the serving cell) where the UE is ready to receive from and transmit to a first set of cells that comprises the serving cell and one or more non-serving cells. After handover, the second coordinated multi-point connection may be controlled by a previous non-serving cell, and the UE may be ready to receive from and transmit to a second set of cells that comprises the previous non-serving cell.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to switch from a first cell of a first distributed unit (DU) to a second cell of a second DU, wherein the first DU and the second DU are included in a set of DUs of a central unit (CU). The UE may communicate, using layer 1 (L1) or layer 2 (L2) signaling to change an activation status of at least one cell of the first DU or the second DU. The UE may switch from the first cell to the second cell in connection with the change to the activation status of the at least one cell of the first DU or the second DU. Numerous other aspects are provided.

A data forwarding method includes receiving, by a session management function network element, information about a first bearer in a first network from an access and mobility management function network element; and sending flow information of a first flow in a second network and forwarding information to the access and mobility management function network element. The flow information indicates a flow for data forwarding, and the forwarding information is used for forwarding the first flow to a tunnel corresponding to the first bearer.

This disclosure relates to the field of wireless communications technologies, and in particular, to a handover method, including: receiving, by a mobility management network element of a first network, a first handover request sent by an access network, and learning that a terminal device needs to be handed over to a second network; obtaining an identifier of the terminal device based on the first handover request; determining, by the mobility management network element of the first network, a target mobility management network element of the second network based on the identifier of the terminal device; and sending, by the mobility management network element of the first network, a second handover request to the target mobility management network element of the second network, and requesting to hand over the terminal device to the second network.

A radio communication equipment installed on a vehicle comprises a radio communicator configured to perform radio communication with a network, and a controller configured to perform call origination to a public safety answering point (PSAP) via the network, wherein the controller is configured to perform first call origination to the PSAP upon occurrence of an emergency, determine whether there is an abnormality in call upon the first call origination, and perform second call origination to the PSAP by a scheme different from a scheme used for the first call origination when there is an abnormality in call upon the first call origination.

The present invention is for transmitting capability information of a user equipment (UE), and a method of operating an electronic device according to various embodiments may comprise receiving system information from a cell of a first radio access technology (RAT); generating a message selectively including capability information of the electronic device for the second RAT according to whether the system information includes information about a cell of a second RAT different from the first RAT; and transmitting the message to the cell of the first RAT. In addition, various embodiments are possible.

According to various embodiments, an electronic device may include at least one processor configured to support a first radio access technology (RAT) and a second RAT, wherein the at least one processor is configured to: receive a radio resource control (RRC) reconfiguration message including a measurement object (MO) from a network, based on the first RAT, and based on dual connectivity (DC) of the first RAT and the second RAT being identified to be restricted, perform a measurement of at least one first frequency satisfying a condition associated with a stand alone (SA) mode among at least one frequency based on the second RAT, which is identified based on the MO, and refrain from performing a measurement of at least one second frequency not satisfying the condition among the at least one frequency.
