The realities of non-terrestrial networks more and more present that protection relies upon as a lot on timing as location
The telecom trade has so lengthy constructed its community optimization technique round one mannequin: a static infrastructure serving a cellular consumer base. Now as non-terrestrial networks (NTNs) enter early deployment, pushed by Starlink and different gamers within the house, and are set to develop into a part of the broader cellular community operations, that mannequin is turning into redundant.
“Once we evaluate NTN with conventional telecom operations, there may be one basic shift. In conventional telecom, the bottom station or antenna is static whereas the customers are cellular. In NTN, that mannequin adjustments: 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 prevailing three dimensions of latitude, longitude, and altitude: time. Satellites transfer at kilometers per second, and relying on their move 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 completely 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 move window.
“If no satellite tv for pc is passing by, an outage is much less pressing. Conversely, if a satellite tv for pc is because of move in a couple of minutes, restoration turns into important,” Bhatt mentioned.
One other essential side is provisioning. A satellite tv for pc passes by a number of international locations in the course of 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 selected area of the U.S., you could 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 have got ‘peak hours’. In NTN, it’s peak hour someplace on this planet always. Operation facilities should retailer knowledge regionally whereas remaining accessible to suppliers,” he mentioned.
“Moreover, one NTN supplier will obtain requests from a number of MNOs (Cell 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 techniques of all these completely different MNOs [mobile network operators].”
Bhatt additionally talked about knowledge sovereignty issues that include bypassing terrestrial borders. “For an NTN operator offering international service, knowledge integrity and localization are main points. If you happen to serve an European telco, you can’t take that knowledge out of Europe, even when the satellite tv for pc passes over the entire world.”
With out temporal consciousness, none of those variabilities may be totally monitored or managed. “You may’t simply consider an NTN operator as a easy extension of your RAN [radio access network]; it’s extra like a fancy roaming companion. We’re proposing adjustments to standardization our bodies, like ETOM [Enhanced Telecom Operations Map] and ITIL [Information Technology Infrastructure Library] to replicate these NTN necessities. It’s a ‘folks, 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 trade’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 international databases, just like the TLE (Two-Line Aspect) 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 have been in a position to do that as a result of Rakuten Cell required it, and our platform structure was versatile sufficient to adapt its knowledge 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 bins to cost handsets in distant places the place energy provide is usually inconsistent.
The corporate has its structure deployed in eight areas globally to adapt to regional regulatory necessities, Bhatt mentioned.
The answer is at the moment getting used in-house at Rakuten Cell, and the corporate can also 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.
