Problems solved by technology

[0005] The existing RSP process has the disadvantage that batches of network resources associated with previously generated and not yet provisioned SIM profiles are blocked and not used until all these SIM profiles are freed for download to the device
In particular, the reusability of IMSI is limited
Second, the system cannot react to the dynamic demands of SIM profile provisioning, since the sharing of SIM profiles between SM-DP+ nodes and MNO nodes forms the basis of RSP, but is performed independently in another process

Embodiment Construction

[0036] In the following description, for purposes of explanation and not limitation, specific details, such as a particular network environment, are set forth in order to provide a thorough understanding of the techniques disclosed herein. It will be apparent to those skilled in the art that the technology may be practiced in other embodiments that depart from these specific details. Furthermore, although the following embodiments are described primarily for 5G New Radio (NR) implementations, it is readily apparent that the techniques described herein may also be implemented in any other radio network, including: 3GPP LTE or its Successors; Wireless Local Area Networks (WLAN) according to the standards series IEEE 802.11; Bluetooth according to the Bluetooth Special Interest Group (SIG), especially Bluetooth Low Energy and Bluetooth broadcasting; and / or based on IEEE 802.15. 4 ZigBee.

[0037] Additionally, those skilled in the art will appreciate that a combination of progra...

Abstract

A technique for operating an RSP node (100), which is configured for remote subscriber identity module, SIM, provisioning, RSP, and comprises or is connectable to an interface (502) for communicationwith an MNO node (200) of a mobile network operator, MNO, is described. As to a method aspect of the technique, a download order message from the MNO node (200) is received through the interface (502). The download order message includes data (604) for generating a SIM profile (602). The SIM profile (602) is generated in response to the download order message according to the data (604) received for generating the SIM profile (602). A result (606) of the SIM profile generation is sent through the interface (502) to the MNO node (200).

Description

technical field [0001] The present disclosure generally relates to techniques for remote SIM provisioning (RSP). More specifically, and without limitation, methods and nodes for RSP communication over an interface are provided. Background technique [0002] The embedded SIM (eSIM) according to the Global System for Mobile Communications Association (GSMA) provides a mechanism for remote provisioning and management of a Subscriber Identity Module (SIM) profile, generally referred to as Remote SIM Provisioning (RSP). RSP allows provisioning of a SIM profile "over the air" for an initial operator, and allows subsequent changing of a SIM profile from one operator to another. A radio or cellular device (short: device), such as an embedded or consumer device for machine-to-machine (M2M) connectivity, queries a subscription manager discovery server (SM-DS) for a subscription manager Address of the data preparation (subscription manager data preparation, SM-DP or SM-DP+) node, and...
