SM-DS Server Event Filtering for Wireless Profile Download
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication system faces limitations in search time and traffic management when an electronic device attempts to download an eSIM profile, as it requires searching multiple relay servers and involves increased traffic between profile preparation and subscription manager discovery servers.
Innovation Solution
A server with processing circuitry is configured to receive and compare information on conditions for forwarding events, determining whether to transmit events between subscription manager discovery servers based on eUICC identifiers, service provider names, or hashed ICCID addresses, thereby reducing unnecessary traffic and search time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device searches for profile preparation server through multiple relay servers (SM-DS), then the device can find the correct server to download profile, but the search time increases significantly
Solution Approach 1:
The profile preparation server (SM-DP+) proactively generates and transmits an event notification to the relay server (SM-DS) when the profile is ready for download. This preliminary action eliminates the need for the electronic device to perform time-consuming searches through multiple relay servers, as the device can directly access the profile preparation server using information contained in the event notification.
2Adaptability or versatility
If the profile preparation server transmits events to multiple relay servers, then the profile can be made accessible to more devices, but the traffic between servers increases
Solution Approach 1:
The relay server (SM-DS) acts as an intermediary that receives the event from the profile preparation server and selectively forwards it to authorized electronic devices. This intermediary mechanism enables broad profile accessibility while controlling server traffic, as the relay server filters and directs events only to devices that have legitimate access rights, rather than broadcasting to all possible devices.

AI summary
A server according to an embodiment includes: a communication circuit, a memory, and at least one processor, comprising processing circuitry, wherein at least one processor, individually and/or collectively, is configured to: receive information on a condition for forwarding an event from another subscription manager discovery server (SM-DS) and store the information in the memory, receive an event indicating that a profile has been prepared from a profile preparation server through the communication circuit, compare information on at least one of an eUICCidentifier (EID), a name of a service provider, an address of the profile preparation server, or a hashed integrated circuit card identifier (ICCID) stored in the memory, based on reception of the event, and determine whether to transmit the event indicating that the profile of the user has been prepared to the another subscription manager discovery server, based on the comparison.
