A user device installs a third-party companion application with a primary software development kit (SDK) for cellular service activation on a wearable device, the wearable device including a third-party device application having an embedded SDK for the cellular service activation. The user device receives user input to initiate the cellular service activation for the wearable device and solicits, via the primary SDK, user input for account settings associated with the cellular service activation. The user device obtains, via the primary SDK and from a network device, activation parameters, associated with the wearable device, for the cellular service activation. The user device forwards, via the primary SDK and to the embedded SDK of the wearable device, the activation parameters, which the embedded SDK uses to request cellular activation.

In some example embodiments, there may be provided an apparatus including at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least: obtain information to enable selection of an access node for a non-GPP access; query a server to determine whether the country at which the access node is located requires lawful interception of communications; and select, based at least on the obtained information and/or a response to the query, the access node for the non-3GPP access. Related systems, methods, and articles of manufacture are also described.

A session management function (SMF) comprises one or more processors and memory. The memory stores instructions that, when executed by the one or more processors, cause the SMF to receive, from a network exposure function (NEF), a message comprising downlink data from an application server and for transmission to a wireless device, and a release assistance indicator (RAI), the RAI indicating, transmission of uplink data by the wireless device is expected subsequent to transmission of the downlink data and a release of a connection associated with the wireless device after the transmission of the uplink data, receive an indication that the uplink data is transmitted, and send, to an access and mobility management function (AMF) based on receiving of the indication, a release message indicating release of a non-access stratum connection associated with the wireless device, the release message comprising the RAI.

The present disclosure relates to a communication method for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G systems, and to a system for same. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) based on 5G communication technology and IoT-related technology.

A narrow-bandwidth terminal device performs radio communication at a bandwidth narrower than a system bandwidth. The narrow-bandwidth terminal device in an idle state camps on a cell, and performs discontinuous reception of a signal transmitted from the cell. The terminal device also determines a reception condition of the signal, for example, whether the signal can be received. When it is determined that the signal cannot be received, the narrow-bandwidth terminal device moves out of a coverage area of the cell while continuing to perform the discontinuous reception. When it is determined that a discontinuous reception timer has been completed, the narrow-bandwidth terminal device continues to perform the discontinuous reception.

A session management function (SMF) may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the SMF to perform operations. The operations may include selecting a user plane function based on a device type of a wireless device, responsive to a session establishment request to establish a packet data unit (PDU) session for the wireless device. An indication of the device type may be provided with the session establishment request. The operations may also include sending, to the user plane function, reporting rules based on a charging policy received from a policy control function (PCF) responsive to a charging policy request to the PCF.
