Description
Technical Field
The application relates to the technical field of communication, in particular to a low-carbon low-cost public-private network joint deployment method.
Background
For 5G energy consumption: as shown in fig. 2: compared with 4G,5G, the spectrum characteristics change obviously: the frequency spectrum becomes more, the bandwidth becomes larger, and the frequency point becomes higher. The cell bandwidth of 4G is 20M maximum; the cell bandwidth of 5G becomes FR1 max 100M; the maximum bandwidth of the 5g f 2 cell is 400M. The bandwidth becomes large, and the frequency point becomes high, resulting in a steep increase in energy consumption at the base station and terminal sides.
For 5G slices: unlike 4G,5G itself faces the mission of powering the vertical industry, so at the beginning of 5G design, the concept of network slicing is designed and enhanced to meet different industry requirements through different data slices; the protocol stack of L2 is added with a SDAP (Service Data Adaptation Protocol) sublayer, so that the Qos (Quality of Service) requirement of data can be met more flexibly.
But the network slicing technology has obvious problems: the broadcast and access procedures cannot be sliced, but only the accessed data services.
In the deployment and joint deployment of public and private networks, the public network is generally used as a main part (broadcast access, some policy configuration and the like are all mainly used as the public network), and then data slicing is opened up for the private network to serve; in a sense, the private network is more like a public network.
If the private network wants to be more independent, the public private network is generally isolated and deployed; for example, the spectrum of 10M is subjected to public-private network joint deployment, and two independent 10M are possibly required to be subjected to public-private network isolation deployment; this increases equipment and energy costs and also loses spectrum pooling benefits.
When public private networks are deployed together in the prior art, in order to ensure the independence of the private network strategies, the following cost or disadvantage exists:
1. multiple independent frequency spectrums are needed to carry out public-private network frequency spectrum isolation;
2. multiple physical devices are required to match the use of multiple frequency spectrums;
3. compared with a single public network, the energy consumption is multiplied due to the increase of frequency spectrum and equipment;
4. due to spectrum isolation, the use of pooling is not possible, resulting in spectrum waste.
