In May 2023, with the joint efforts of the four major operators, the world's first 5G cross-network roaming trial commercial was officially launched in Xinjiang.
You can easily switch to other carriers' networks without changing cards, numbers, or additional fees, and you don't have to worry about "others have a network but you don't have a network".
But today, more than half a year has passed, and there seems to be no news about 5G roaming.
Don't worry, China Mobile officially announced the launch in the past two days".In 2024, the 700MHz 5G core network cross-network roaming (Xinjiang) test network engineering equipment will be centrally procuredThe total budget is 9.7 million yuan (excluding tax), and 5G cross-network roaming is really coming!
In the 5G era, operators who have always been "at odds" are forced to start the co-construction and sharing of 5G due to the cost pressure of network construction.
China Mobile has joined hands with Radio and Television to launch 700MHz 5G co-construction and sharing, in order to reduce costs and increase efficiency, and optimize users' network experience.
The same is true for 5G cross-network roaming, where the four major operators can share a single network in remote and rural areasReduce network construction costs and accelerate 5G network coverage; It can also help users say goodbye to "signal blind spots" and enjoy high-speed network coverage services, killing two birds with one stone.
For operators, it is generated during the construction of a complete 5G network by one operator in a certain area, and other operators access it through roaming, and then provide corresponding network services to their own usersInter-network settlement feeAt the operator's expense.
InTechnologyIn terms of aspects, since the trial commercial use of 5G cross-network roaming jointly launched by the four major operators is the first in the world, there is no technical experience to learn from.
5G cross-network roaming requires an independent core network, and when establishing a roaming connection between the visiting operator and the home operator, it is necessary to ensure the security of interfaces, signaling, data, and disaster recovery, and ensure the confidentiality and integrity of the transmission process.
At the same time, operators should fight a good "cooperation battle" with each other, and in the practice of trial commercialization, they should explore the optimal configuration plan together and discuss it togetherAppropriate roaming billing**。It is not possible to "recover the principal" of the attributable operator because of the low inter-network settlement price, nor can it cause the "pressure service" of the visiting operator due to the excessively high settlement**.
How to set prices is one of the key issues that operators need to solve urgently when they implement 5G cross-network roaming commercialization.
For operators who don't have a solid family background, it is very cost-effective to "rub" the network of other operators through roaming on different networks.
Before re-cultivating the 800MHz and 900MHz frequency bands for 5G systems, China Telecom and China Unicom have repeatedly expressed their desire to cooperate and share 700MHz 5G low frequency bands to improve the competitiveness of their network services in remote and rural areas.
At the beginning of this year, the Ministry of Industry and Information Technology, the National Development and Reform Commission and other 11 departments jointly issued the "Notice on Carrying out the Special Action of "Signal Upgrade", pointing out that it is necessary to strengthen the network coverage of key scenarios and promote the gradual extension of 5G networks from "city to city" to "county and county", and to towns and administrative villages.
5G cross-network roaming can quickly improve the quality of network coverage by "rubbing" the networks of other operators.
On the other hand, users can seamlessly switch to the network of other operators when they cannot receive the network signal of the operator to which they belong, ensuring that the signal will never drop, and optimizing the user's service perceptionIt is also a good choice to choose 5G cross-network roaming to promote "signal upgrade".
According to the unified planning and deployment, 5G cross-network roaming will be the first to be commercialized in remote areas of China, and the technical test will have little impact on existing network users, and can also balance the relationship between high network construction costs and signal blind spots in remote areas.
At present, operators are actively cooperating with mobile phone terminal manufacturers, such as vivo, OPPO, Xiaomi, etcMainstream mobile phone brands all support 5G cross-network roaming function
From the official announcement of the trial commercial to the start of centralized equipment procurement, 5G cross-network roaming is getting closer and closer to us, are you looking forward to it?
