Provided is a communication unit for achieving, in a 5GS, in a case that a situation occurs in which information for connectivity to a Local Area Data Network (LADN) requested by a user equipment is not valid, error processing of a control device of a core network and error processing of the user equipment. Provided is a communication unit for achieving, in a 5GS, in a case that a situation occurs in which information for connectivity to a Local Area Data Network (LADN) requested by a user equipment is not valid, error processing in which a control device of a core network rejects the request of the user equipment. Also provided is a communication unit for achieving, in a case that a situation occurs in which information for connectivity to a LADN requested by a user equipment is not valid, appropriate error processing performed by the user equipment.

Various arrangement of compound cellular networks that accommodate multiple cellular communication protocols are presented. A compound cellular network may connect user equipment (UE) with a data network using a first anchor point. The compound cellular network may transition the UE from the first anchor point to a second anchor point. Following the transitioning, the compound cellular network may connect the UE with the data network using the second anchor point. The UE may then be transitioned from the second anchor point to a converged anchor point of the compound cellular network. The UE may be locked to the converged anchor point while the UE is communicating with a second cellular network that communicates using the second cellular communication protocol.

Selecting local gateways for VoWiFi and/or ViWiFi calls (voice traffic sessions) for a user equipment (UE) includes: receiving, by an evolved packet data gateway (ePDG), a request to initiate the voice traffic session from a WiFi router outside a cellular network that is communicatively coupled with the UE; based on at least an internet protocol (IP) address of the WiFi router or the UE, determining a geographical location of the UE; based on at least the geographical location of the UE, determining a tracking area code; based on at least the tracking area code, determining an IP address of a network gateway proximate to the UE, wherein the network gateway comprises a user plane function (UPF) and a session management function (SMF) or a packet data gateway (PGW) user plane function (PGW-U) and a PGW control plane function (PGW-C); and establishing the voice traffic session using the network gateway.

A method for automatically attaching a purpose-built electronic device to a provider network includes steps of discovering, by a Wi-Fi module of the purpose-built electronic device, a wireless data network in operable communication with the provider network selecting, by the Wi-Fi module, the wireless data network, transmitting a primary authentication certificate from the Wi-Fi module to an authentication, authorization, and accounting server of the provider network, receiving, by an application server of the provider network, a secondary authentication certificate from a functionality module of the purpose-built electronic device authenticating, by the provider network, the primary and secondary authentication certificates, and attaching the purpose-built device to the provider network.

Examples disclosed herein provide systems, methods, and software to manage communication paths for wireless communication devices. In one example, a method of operating a mobility management entity includes receiving a plurality of status reports from a plurality of packet data network gateways, and identifying a communication request for a wireless communication device. The method further includes determining a communication path for the wireless communication device based on the plurality of status reports, and initiating a communication for the wireless communication device via the communication path.

Methods, apparatus, and systems for selecting appropriate gateway servers for user devices with different device capabilities are disclosed. In one example aspect, a wireless communication method includes provisioning multiple wireless electronic devices of a user with a first access point name, and receiving, from a wireless electronic device of the multiple wireless electronic devices of the user, a request for establishing a data session. The method also includes determining, in part based on a capability of the wireless electronic device, a second access point name that is different from the first access point name and selecting a packet gateway server corresponding to the capability of the wireless electronic device using the second access point name. The method further includes establishing the data session between the packet gateway server and the wireless electronic device.

Methods and apparatus for configuring network connections using memory are described. An example method for use in mobile equipment includes: reading a mobile subscriber identity from a memory device associated with the mobile equipment; determining if part or all of the mobile subscriber identity matches a data set entry within a file associated with the mobile equipment; determining if an elementary file is on the memory device; when the elementary file is on the memory device, determining if an access point name is stored in a location identified in the elementary file; and when the access point name is stored in the location identified in the elementary file, using the access point name to connect the mobile equipment to a mobile network. Other examples are disclosed.

Embodiments described herein relate to a method of selecting a cell for communication over a network, the method comprising: determining a round trip delay (RTD) measurement from a device to each of a plurality of base stations, each of the plurality of base stations being in a respective one of a plurality of cells; ranking the plurality of cells based at least in part on the RTD measurements; selecting the highest-ranked cell; and initiating attachment to the selected cell.

An information processing apparatus including: a communication processor; a controller that makes the communication processor be in a port opened state when the information processing apparatus is powered on; and a setting processor that sets connection information in the communication processor made into the port opened state by the controller through executing a program file to set the connection information. This configuration makes it possible to easily set communication setting information.

A radio access network (RAN) slice provides radio access to a communication network for a user equipment. The RAN slice is uniquely identified by a RAN slice identifier. The RAN slice includes: a base station for providing access to the RAN slice for the user equipment; an access and mobility management function (AMF) entity configured to handle the RAN slice identifier identifying the RAN slice; and a session management function (SMF) entity configured to handle data communications of the user equipment over the RAN slice. The base station is configured to receive an attach request originating from the user equipment to connect to the RAN slice, and to reject access to the RAN slice in response to the attach request not comprising the RAN slice identifier.
