  • Publication number: 20250212286
    Abstract: An apparatus configured to operate as a central unit control plane (21) of a radio access network node (1) sends to a central unit user plane (22) of the radio access network node (1) a single control message indicating that one or more Packet Data Convergence Protocol (PDCP) count values for an Acknowledged Mode (AM) data radio bearer (DRB) already configured for a radio terminal (4) need to be reset. This can help, for example, to facilitate the resetting of a PDCP count value for an AM DRB by a radio access network node using an architecture in which its control plane and user plane are separated.

  • Publication number: 20250212160
    Abstract: Example embodiments of the present disclosure relate to methods, devices, and medium for communication. A terminal device receives, from a core network device, an LPP message informing the terminal device to activate an AI-based positioning for determining location related information based on an output of the positioning model; and transmitting the location related information to the core network device. In additional, an interaction between an access network device and a core network device via NRPPa is triggered to activate an AI-based positioning for determining location related information based on the output of a positioning model, and transmitting the location related information to the core network device. In this way, a procedure between the terminal device and the core network device is defined and thus the positioning accuracy may be improved.

  • Patent number: 12339984
    Abstract: Access right information (20) indicating an access right of a user for a target file (10) is stored in a storage device (3100) accessible from a server apparatus (3000). A management apparatus (4000) acquires the access right information (20) from the server apparatus (3000) and puts it in a storage device (4100). The management apparatus (4000) acquires a request for key information that is used to decrypt a target file (10) from a user apparatus (2000) operated by a target user (40). The management apparatus (4000) determines, upon the acquisition of the request, whether or not the target user (10) has an access right for the target file (40) by using the access right information (20) stored in the storage device (4100). The management apparatus (4000) outputs the key information to the user apparatus (2000) when it is determined that the target user (40) has the access right for the target file (10).
