These insights from Hwang’s resume paint an even clearer picture of the technical groundwork that might be underpinning the patent’s application in real-world devices.

Clue 2: Samsung’s Patent

Being intrigued by those details, we decided to assess the patent through official sources. We turned to Korea Intellectual Property Rights Information Service (KIPRIS) to validate the patent.

Eventually, we located it and confirmed that it was filed by Samsung on 7th December 2021. This was a rather curious detail given that Hwang’s internship ranged from February 2022 to June 2022.

Nonetheless, as we dove deeper into the patent, we were able to confirm its contents including Samsung’s claims about the tech, and diagrams presented originally in Korean.

Understanding the Patent: From Jargon to Clarity

Given the patent was originally in Korean, we used a combination of AI and Google Translate to translate the patent to English, and hired an engineer to help us decode the patent. Going through this process we realized that the 20 claims listed on the KIPRIS website summarize the entire patent and its technical information well.

The patent describes a new system that Samsung has worked on to improve roaming capabilities of smartphones. The essential claims can be summarized below:

  • The technology includes a memory to store information and two circuits for communication: one for cellular communication, and another for Bluetooth Low Energy (BLE) integration. There will be at least one processor that interlinks these components.
  • The processor will be responsible to detect when the phone is in a new country (i.e. roaming).
  • Upon detecting presence in a foreign land, the phone will use BLE to communicate with devices nearby to decide the best available network to connect to. This process will either be preferred over using cellular networks or used in conjunction with the traditional method.
  • The processor also identifies Public Land Mobile Networks (PLMNs) using the information gathered and then manages searches and registrations through the cellular communication circuit.

In Layman’s Terms

What is BLE?

Bluetooth Low Energy (BLE) is a technology designed to transmit data over short distances from one device to another. BLE uses very small amounts of power, affecting your battery almost negligibly. This technology is often used in fitness trackers and smartwatches amongst other devices to communicate tiny amounts of data. Think of it like a lighthouse that emits signals intermittently, guiding nearby ships.

What are PLMNs?

Public Land Mobile Networks (PLMNs) are the official networks that mobile operators provide in a country. It is essentially the network your phone connects to to receive calls, texts or use data.

What does the patent say?

Imagine you are traveling to a different country with your new Samsung Galaxy S25. The moment you land and turn off your Airplane mode, your phone needs to search for the best network to connect to, so that you can continue receiving calls, texts or using your data.

Normally, a phone would use traditional cellular signals to figure out the best network, which not only can be slow, but also costly.

However, the S25 will use BLE to talk to other devices nearby that are already connected to the best network, and use that information to connect your device to the same network as well. Think of it as asking locals for advice instead of trying to follow an internet guide or figuring it out all on your own while traveling. However, at this point, it is unclear if the nearby devices also have to be Samsung devices for this technology to function as suggested.

Technical workflow explained:

Here is the main technical workflow diagram from the patent:

Samsung Galaxy S25 Roaming Technology Patent Diagram from KIPRIS discovered by TrueTech
Technical Workflow – Samsung Patent from KIPRIS, discovered by TrueTech

Here is an easy explanation of the diagram:

  • The Galaxy S25 (or the processor connecting the patented tech) checks if you are in a new country.
  • If so, it uses BLE to get network information from nearby devices.
  • The phone uses information obtained to detect which PLMN to use.
  • It connects to the best PLMN (cellular network).
  • The process terminates when the phone is registered and connected to the new network.

In addition to that, looking back at Hwang’s internship experience description, he also referenced the “key-value storage system” being capable to handle “400+ PLMNs per device.” This perhaps refers to the memory in the patent. In our interpretation, this patented system will be able to store and handle information from over 400 PLMNs at once, making connection and reconnection faster.

While we did our best to explain the patent, its technical details, and how it would benefit you in your day to day life, there are intricacies that can only be gathered by experts after perusing the patent thoroughly. Below are the claims that the patent explores including their translations.

Final Thoughts

The two clues clarifies on Samsung’s focus to improving overall connectivity of their devices when traveling. Should this technology be implemented on the next Galaxy device, the amount of time you have to wait for your phone to connect to a network after turning airplane mode off will reduce significantly.

The use of BLE intriguing to us. Such technology also opens gates to faster connectivity when you are in a region where traditional network search might be more difficult. Devices can inter-connect and communicate with each other to reduce the load that traditional cellular connectivity search can put on your phone’s battery.

Overall, it is interesting to see Samsung pursue a front that is less explored. A faster roaming connectivity experience could make the upcoming S25 more appealing to users who travel internationally often, while giving Samsung devices an edge when compared to iPhone’s satellite connectivity, despite the two technologies being significantly different.
