This disclosure above describes a method and system for reliably delivering and receiving paging message and reducing power consumption. The method includes: sending, by a first network element of a wireless communication network, a first paging message targeting a UE and comprising a first set of paging parameters to a second network element of the wireless communication network; identifying, by the first network element, a paging failure condition associated with the first paging message; and sending, by the first network element, upon the identification of the paging failure condition, a second paging message targeting the UE and comprising a second set of paging parameters different from the first set of paging parameters to the second network element.

Devices, methods, and computer-readable media described herein and provide for sending, by a first wireless station, a suspend message to a wireless station associated with a radio resource control (RRC) session for a dual connectivity (DC) capable user equipment (UE) device that places the DC capable UE device in an RRC inactive mode; storing, by the first wireless station, UE context information from a core network for the DC capable UE device for the RRC session; and evaluating, by the first wireless station, a set of criteria to determine whether to also store the UE context information at the wireless station

Apparatuses, methods, and systems are disclosed for indicating a packet data unit session as unavailable. One apparatus includes a processor that determines that at least one packet data unit session is unavailable. The apparatus includes a transmitter that transmits information indicating that the at least one packet data unit session is to be released.

Disclosed are a communication scheme and a system thereof for converging an IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. The present disclosure can be applied to intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on the 5G communication technology and the IoT-related technology. The present disclosure relates to a method of a session management function (SMF) entity in a communication system.

A method, a device, and a non-transitory storage medium are described in which a frequency and network slice selection service is provided. The service may configure network slices at a cell level which may include carrier frequencies or bands that may be ranked in terms of preference for a network slice. The service may provide frequency/band-network slice information to end devices via system information block and radio resource control messages. End devices may perform a cell search procedure and use other criteria to select and establish a network slice connection via a frequency/band of a network slice and in accordance with the service.

In a 6G network, microservices can be utilized in the absence of a core network. For example, after a mobile device has authenticated, through its carrier network, with a transport service layer, microservices can be allocated to the mobile device without having to be transmitted via the core network. Thus, removing the core network from the process can generate a direct line of microservices from the transport layer to the end-user. Furthermore, additional microservices and/or resources can be access through a microservices library. Consequently, packets can be securely transmitted be a wireless network facilitating sending packet profile data from one to many node devices in anticipation of the packet traversing the various node devices.

Provided in one disclosure of the present specification is a method for operating a session management function (SMF) node for managing a protocol data unit (PDU) session. The method can comprise a step of obtaining analysis information from a network data analytics function (NWDAF) node. The obtained analysis information can comprise information relating to a user equipment (UE) presence pattern analysis in a local are data network (LADN) service area. The method can comprise a step of determining a procedure to be performed for the LADN PDU session on the basis of the information relating to the UE presence pattern analysis.

A communication method and apparatus. A first access network device determines that a first terminal device is a last terminal device that receives data of a first multicast service via the first access network device in response to the first terminal device being in a handover preparation phase in which the first terminal device is handed over from the first access network device to a second access network device. The first access network device sends first information that is used to release a first tunnel. The first tunnel is used to transmit the data of the first multicast service between the first access network device and a core network device.

Presented are systems, methods, apparatuses, or computer-readable media for data forwarding in centralized unit (CU) and distributed unit (DU) split architectures. A DU may receive, from a CU, context information for forwarding of data from a wireless communication device that is in radio resource control (RRC) inactive state. The DU may receive, from the wireless communication device, the data from the wireless communication device that is in RRC inactive state. The DU may process the data according to the context information. The DU may send, to the CU, the processed data according to the context information.
