Various techniques are described herein for autonomously registering and/or activating Internet-of-Things (IoT) devices, provisioning wireless network access of those devices, and connecting the IoT device to an NB-IoT network with agreed-to terms for network usage. In various embodiments, IoT devices may be configured to negotiate for NB-IoT network access by (i) sharing their data with the NB-IoT network provider, (ii) security storing and using cryptocurrency to obtain NB-IoT network access, and/or (iii) automatically providing the NB-IoT network provider with access to data from other associated IoT devices and/or with payment from a separate payment provider. Individual IoT devices may be preconfigured with negotiation terms for NB-IoT network access, pre-associated with other devices/users, and/or pre-loaded with cryptocurrency in a secure storage.

Convergence of a 5.sup.th-Generation communication system supporting higher data rates beyond 4.sup.th-Generation system(s) with a technology for Internet of Things (IoT) may be applied to intelligent services. Operator specific services are permitted and provided by allowing an unauthorized terminal to search for and access the such services, and includes notifying a terminal of information corresponding to “operator specific services” by allowing a base station to broadcast predetermined information, displaying information acquired by a terminal, matching information acquired by the terminal with information broadcast from a base station to arrange services, requesting access and notifying a terminal performs an access for “operator specific services” upon accessing a network, providing a menu for determining whether neighboring base stations are capable of “operator specific services” to a user of a terminal, and allowing the terminal to determine whether there is the base station broadcasting the information.

The disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate after a 4G communication system such as LTE. A method according to an embodiment of the disclosure is a control method in an edge enabler server (EES) of a mobile edge computing system, and may include subscribing to a user plane path change event at an edge application server (EAS); determining an application context relocation (ACR) based on receiving a user plane path management event notification from the mobile communication network in case of subscribing to the user plane path change event for the EAS; transmitting an ACR request message to the EAS; receiving an EAS response message from the EAS; and transmitting an application function (AF) acknowledgment message to a first node of the mobile communication network in response to receiving the EAS response message from the EAS.

Embodiments of this application provide a data transmission method, a multi-function card, and an electronic device. The multi-function card may work as a SIM card or a memory card by using electrical contacts through time division multiplexing. Data is transmitted between the multi-function card and a processor in the electronic device, so that a function of subscriber identity identification can be implemented, and a storage capacity of the electronic device can be expanded. Storage space expanded in the electronic device may be used to store a picture, audio, a video, and an application program. The data transmission method and the multi-function card provided in embodiments of this application may be used to save physical space in the electronic device. This is conducive to lightening and thinning of the electronic device.

Electronic subscriber identity modules (eSIM) can be more susceptible to hackers and more vulnerable than physical subscriber identity modules. The current disclosure discusses systems and methods to facilitate eSIM security by utilizing a management software application (MSA) hosted on a mobile device. This MSA can cross-reference eSIM registration data with mobile device signature data to determine if the correct user identity is associated with mobile device prior to an eSIM being issued to the mobile device. Additionally, various degrees of data flagging can be utilized to allow an end user to properly address an indication of mobile device vulnerability.

In order to ensure that a Subscription Concealed Identifier, SUCI, is calculated in the Universal Subscriber Identity Module, USIM, part of a User Equipment, UE, when intended, when a SUCI-Calculation-Indicator is set to a value indicating that the SUCI should be calculated in the USIM, a network node sets proprietary information, which is not known to a Mobile Equipment, ME, part of the UE, as required for calculation of the SUCI. The USIM facilitates calculation of the SUCI in the ME part of the UE only when the SUCI-Calculation-Indicator is set to a value indicating that the SUCI should be calculated in the ME. When the SUCI-Calculation-Indicator is set to a value indicating that the SUCI should be calculated in the USIM, the ME part deletes any locally stored information required for calculation of the SUCI.

Methods for determining a default network slice are provided. More specifically, the methods include determining a default Single Network Slice Selection Assistance Information (S-NSSAI) that identifies the default network slice for establishing a Protocol Data Unit (PDU) session for an application in a wireless device without an S-NSSAI association. Various embodiments for determining the S-NSSAI are also disclosed herein. By determining the default network slice, it is possible to eliminate existing ambiguity associated with establishing a PDU session for application without S-NSSAI association, thus helping to reduce implementation complexity in a wireless device and/or a core network node.

The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first modified request.

A method and a wireless communication device for providing communication service to devices connected to the wireless communication device. By establishing a starter wireless carrier connection using a starter SIM from a plurality of local SIMs, the wireless communication device establishes one or more logical data connections with one or more SIM banks. Remote-SIMs are selected from the one or more SIM banks and used to establish further wireless carrier connections to allow communication service to be provided to the devices over wireless carrier connections.
