Methods and apparatus for receiving downlink data packets over Non-Third Generation Partnership Project (N3GPP) access. A User Equipment (UE) is configured to manage the triggering of Service Request procedures for receiving N3GPP Mobile Terminating (MT) packets in a coverage area of N3GPP access from a 5th Generation (5G) network. A Service Request procedure is triggered by the UE if the UE detects that the UE is in the coverage area of N3GPP access and that the UE is in 5th Generation Mobility Management (5GMM)-IDLE mode over N3GPP access and the back-off timer has expired. The detection is based on the UE determining that an access stratum connection is established between the UE and the 5G network over N3GPP access.

Examples pertaining to selection of a current tracking area identifier (TAI) among multiple current TAIs in non-terrestrial network (NTN) communications are described. A user equipment (UE) initiates a procedure in a satellite-accessing cell of a selected public land mobile network (PLMN). The UE selects a tracking area code (TAC) from a plurality of TACs of the selected PLMN broadcast by the cell as a current TAC such that a tracking area identifier (TAI), constructed from the current TAC and a PLMN identifier (PLMN ID) of the selected PLMN, is a current TAI associated with a geographical area in which the UE is located.

A communication apparatus includes an authentication unit that sets a communication parameter for connecting to a wireless network, and executes authentication processing, with a base station, for registering the communication apparatus to the base station that forms the wireless network, as a management apparatus that is allowed to connect another apparatus to the wireless network, a setting unit that, based on information acquired from code information captured through imaging, sets the communication parameter to another communication apparatus corresponding to the code information, and a registration unit that executes registration processing for registering the other communication apparatus to the base station as the management apparatus, based on at least a condition that the communication parameter is set to the other communication apparatus by the setting unit.

Systems, methods, apparatuses, and computer program products for dynamically updating routing identifiers (IDs) are provided. One method may include deciding, at a network node, to update a routing identifier for at least one user equipment. The method may then include obtaining or generating a new routing identifier to be assigned to the at least one user equipment along with authentication vectors, and transmitting the new routing identifier to an authentication entity.

A method comprising: determining, by a user equipment, that a non-closed access group cell is available to the user equipment in a public land mobile network, wherein the public land mobile network is identified by a public land mobile network identity and the user equipment is only allowed to access the public land mobile network via one or more closed access group cells; displaying the public land mobile network identity to a user; receiving user input selecting the public land mobile network identity; and transmitting a registration request to the public land mobile network identified by the public land mobile network identity.

A method for transmitting in a communication network uplink data from an application module in a user terminal. The method includes: determining, by said user terminal, if a correspondence exists between an application module providing at least one uplink packet and at least one rule designating a network slice instantiation to be used for transmitting uplink packets in the communication network; and in response to a determination by said user terminal that the application module providing at least one uplink packet corresponds to a rule designating a network slice instantiation to be used for transmitting the uplink packet in the communication network, transmitting said at least one uplink packet from the user terminal to an entity for access to a user plane of the designated network slice instantiation.
