    摘要： An apparatus for retrieving at least one of an access network or core network assigned user equipment identifier (NGAP ID) from outside of the access or core network using IP addressing information. The apparatus has means configured to: receive IP addressing information of the user equipment; determine a subscriber permanent user identity for the user equipment from the IP addressing information; generate and transmit a request for the at least one of the access network or core network assigned user equipment identifier, the request including the subscriber permanent identity; and receive the at least one of the access network or core network assigned user equipment identifier.

    摘要： Systems, methods, apparatuses, and computer program products for inter-gNB small data transmission (SDT) routing at a radio access network (RAN). A method may include transmitting an initial request message from a first element in a first network node, to a second element in the first network node to obtain context information. The method may also include receiving, at the first element, a context setup request message based on the context information containing a transport layer information of a third element of a second network node and context information of a user equipment in the second network node. The method may further include processing a data packet according to the received context information. In addition, the method may include forwarding the data packet to the third element of the second network node according to the received transport layer information.
