The realities of non-terrestrial networks more and more present that protection relies upon as a lot on timing as location
The telecom business has so lengthy constructed its community optimization technique round one mannequin: a static infrastructure serving a cellular person base. Now as non-terrestrial networks (NTNs) enter early deployment, pushed by Starlink and different gamers within the house, and are set to grow to be a part of the broader cellular community operations, that mannequin is turning into redundant.
“Once we examine NTN with conventional telecom operations, there may be one elementary shift. In conventional telecom, the bottom station or antenna is static whereas the customers are cellular. In NTN, that mannequin modifications: the customers are comparatively static in a given space, however the antennas [satellites] are transferring,” mentioned Anshul Bhatt, chief product officer of the OSS (Operations Help Methods) enterprise unit at Rakuten Symphony, a subsidiary of Japan’s Rakuten Group that sells OSS/BSS and automation options.
The inversion introduces a fourth factor to the present three dimensions of latitude, longitude, and altitude: time. Satellites transfer at kilometers per second, and relying on their go home windows, the protection and capability change. NTN cells can seem and disappear over a sure geography in issues of minutes, resulting in real-time variabilities in protection.
Equally, places served by smaller or older satellites have totally different protection and high quality of connection than these on the trail of larger and newer ones. This makes protection and latency of NTNs extremely dynamic and time-dependent.
Bhatt famous that incident precedence too turns into conditional. For instance, in a static terrestrial community, a cell website outage requires pressing restoration, whereas within the case of NTNs, the precedence shifts relying on the satellite tv for pc go window.
“If no satellite tv for pc is passing by way of, an outage is much less pressing. Conversely, if a satellite tv for pc is because of go in a couple of minutes, restoration turns into vital,” Bhatt mentioned.
One other essential facet is provisioning. A satellite tv for pc passes by way of a number of international locations through the course of a day, and that requires geological cell provisioning that’s adaptive to the satellite tv for pc schedules and altering conditions.
“For instance, if there’s a hurricane in a particular area of the U.S., it’s possible you’ll must configure the satellite tv for pc on-demand to supply emergency companies for an operator like AT&T. Provisioning have to be dynamic and adapt to satellite tv for pc schedules,” he mentioned.
The operational burden grows with the scope of protection. “In conventional telecom, you could have ‘peak hours’. In NTN, it’s peak hour someplace on the earth always. Operation facilities should retailer information domestically whereas remaining accessible to suppliers,” he mentioned.
“Moreover, one NTN supplier will obtain requests from a number of MNOs (Cellular Community Operators)—like Rakuten in Japan, Reliance Jio in India, or AT&T within the U.S.—all desirous to configure protection on the identical satellite tv for pc. The NTN operator should combine with the ticketing and configuration programs of all these totally different MNOs [mobile network operators].”
Bhatt additionally talked about information sovereignty issues that include bypassing terrestrial borders. “For an NTN operator offering world service, information integrity and localization are main points. When you serve an European telco, you can not take that information out of Europe, even when the satellite tv for pc passes over the entire world.”
With out temporal consciousness, none of those variabilities will be totally monitored or managed. “You’ll be able to’t simply consider an NTN operator as a easy extension of your RAN [radio access network]; it’s extra like a posh roaming companion. We’re proposing modifications to standardization our bodies, like ETOM [Enhanced Telecom Operations Map] and ITIL [Information Technology Infrastructure Library] to mirror these NTN necessities. It’s a ‘individuals, course of, and product’ equation that we have to get proper,” he argued.
Rakuten Symphony’s resolution
Rakuten Symphony has developed what it calls the business’s first NTN-specific OSS system that comes with dynamic topology consciousness, real-time intelligence, and automatic provisioning for granular service consciousness. The answer features a satellite-specific dashboard view that integrates with world databases, just like the TLE (Two-Line Component) and SATCOM databases to correlate satellite tv for pc paths with terrestrial community companies.
“That is the primary time an OSS stack is being redesigned particularly for NTN. We had been in a position to do that as a result of Rakuten Cellular required it, and our platform structure was versatile sufficient to adapt its information mannequin and stock schema,” Bhatt added.
Measuring actual buyer expertise is simply as essential to guarantee NTN networks , and for that Rakuten Symphony is utilizing solar-powered probe containers to cost handsets in distant places the place energy provide is commonly inconsistent.
The corporate has its structure deployed in eight areas globally to adapt to regional regulatory necessities, Bhatt mentioned.
The answer is at present getting used in-house at Rakuten Cellular, and the corporate can be working with a number of operators and satellite tv for pc suppliers in each geostationary Earth orbit and low Earth orbit satellite tv for pc, Bhatt mentioned.
