In order to better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in related technologies are described:

In one embodiment, please refer to Figure 2, which shows a schematic diagram of the expanded spectrum ranges of countries A and B on the predetermined frequency band. as followed:

The spectrum range of n77 before the expansion in country A is 3700 to 3980MHz;

The expanded spectrum range of n77 in country A is 3450 to 3550MHz and 3700 to 3980MHz;

The spectrum range of n77 before expansion in country B is 3450 to 3650MHz;

Country B’s expanded n77 spectrum ranges from 3450 to 3650MHz and 3650 to 3980MHz.

In one embodiment, in order for the terminal to comply with local communications regulations, before a spectrum license is issued to the terminal, a software locking method is used to restrict the terminal to only work on the locally authorized spectrum. In this way, different restricted terminals will appear on the market.

In one embodiment, there will be at least one of the following terminals in the network of country A:

Only supports n77 terminals before expansion, that is, terminals that only support 3700 to 3980MHz, which can also be called traditional country A terminals;

Terminals that support expanded n77, that is, terminals that support 3450 to 3550MHz and 3700 to 3980Mhz, can also be called new country A terminals;

As well as traditional global terminals and new global terminals, the corresponding spectrum range is 3300 to 4200MHz.

Using NS value to indicate the spectrum range supported by the network can prevent traditional terminals from staying on the network, but it violates the original purpose of NS value, and different NS values need to be defined for different expansion requirements and operators in different regions. For example, a new NS value needs to be defined to meet the needs of country B. If the spectrum in the United States is expanded again, a new NS value needs to be defined.
