DoCoMo reported with the ability to cut back paging sign congestion by 15% at peak calling occasions
Japanese cell community operator NTT DoCoMo has examined a hybrid quantum-computing-based community optimization method from D-Wave Quantum, and plans to deploy the answer at its department places of work over the approaching months.
DoCoMo was ready to make use of the hybrid quantum resolution to attain “demonstrable cell community efficiency enhancements,” in keeping with a joint press assertion from the 2 corporations. Particularly, DoCoMo use the quantum optimization to ease congestion at cell base stations throughout peak calling occasions by lowering paging indicators by 15%, by means of prediction of cell gadget motion patterns and subsequent optimization of which base station gadgets would hook up with.
The pilot testing was performed in components of Japan’s Tokai, Chugoku and Kyushu areas and in comparison with typical strategies of approaching the identical drawback.
As D-Wave defined it, its hybrid-quantum know-how was used to “optimize base station monitoring areas — that are small geographical areas — that collectively ship paging indicators and course of in depth historic knowledge on gadget actions between stations.” That helped NTT DoCoMo to foretell future gadget motion patterns and “decide the perfect mixture of base stations to re-establish connections as gadgets transfer between monitoring areas,” the businesses stated.
“The information quantity transmitted by means of paging indicators has been growing, and if there isn’t a response from the terminal, knowledge have to be resent over a wider space. As well as, the latest proliferation of smartwatches and IoT gadgets has resulted in an elevated quantity of paging indicators, which has put a burden on base station services, producing a problem,” DoCoMo stated in a June 2024 paper describing the scope and results of the quantum trial. DoCoMo stated that this was the primary demonstration of growth of an algorithm that reduces paging signaling utilizing a quantum pc.
“Whereas a general-purpose solver took 27 hours, D-Wave’s hybrid solver accomplished the identical process in simply 40 seconds,” in keeping with D-Wave and DoCoMo. “The check outcomes confirmed that quantum optimization led to a 15% discount in paging indicators, permitting roughly 1.2 occasions extra terminals to be related in periods of excessive name quantity.”
“We anticipate that our quantum optimization technique will additional refine community effectivity, permitting us to take care of high-quality service with out further infrastructure investments as community site visitors will increase,” stated Takatoshi Okagawa, director of analysis and growth technique at NTT DoCoMo. “With D-Wave’s hybrid quantum know-how, we intention to set a brand new normal within the telecommunications business for operational efficiency.”
With proof of the quantum resolution’s applicability to enhancing community efficiency, DoCoMo says additionally it is making use of quantum optimization throughout its different enterprise items, together with together with finance, retail, site visitors and logistics, amongst others.
“Telcos are confronted with a slew of accelerating operational complexities — from 5G implementation to ever-shifting shopper calls for — and want novel options to take care of a aggressive edge,” stated Dr. Alan Baratz, CEO of D-Wave. “DoCoMo’s profitable pilot sends a transparent sign — that at the moment’s quantum applied sciences are able to fixing telcos’ advanced optimization issues, with the potential to raise buyer satisfaction, keep community efficiency and mitigate rising infrastructure prices.”
