Of course, it can be understood by those skilled in the art that the embodiments provided in the present disclosure can be implemented alone, or in combination with other embodiments of the methods in the present disclosure, or in combination with some methods in other related technologies; the disclosed embodiments are not limited thereto.

In order to better understand the technical solution described in any embodiment of the present disclosure, first, an application scenario in the related art is explained:

in one embodiment, please refer to fig. 2, which shows a schematic diagram of countries a and B after spectrum ranges of predetermined frequency bands are extended. Sequentially comprises the following steps:

the spectrum range of n77 before the expansion of nation A is 3700 to 3980 MHz;

the spectrum range of n77 after the expansion of nation A is 3450 to 3550MHz and 3700 to 3980 MHz;

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

the spectrum range of n77 after B is 3450 to 3650MHz and 3650 to 3980 MHz.

In one embodiment, in order to make the terminal meet local communication regulations, before the terminal is issued with the license plate of the frequency spectrum, a software locking mode is adopted to limit the terminal to only work on the locally authorized frequency spectrum. So that differently restricted terminals will appear on the market.

In one embodiment, a terminal of at least one of the following may exist in the network of country a:

a terminal only supporting n77 before extension, namely a terminal only supporting 3700 to 3980MHz can also be called a traditional A-country terminal;

terminals supporting n77 after expansion, i.e. terminals supporting 3450 to 3550MHz and 3700 to 3980MHz, may also be referred to as new country a terminals;

as well as legacy global terminals and new global terminals, corresponding to a spectrum range of 3300 to 4200 MHz.

There is a network in nationality a of at least one of:

a network supporting only n77 before extension, namely a network supporting only 3700 to 3980MHz, can also be called a traditional network;

a network supporting n77 after expansion, i.e. a network supporting 3450 to 3550MHz and 3700 to 3980MHz, may also be referred to as a new network;

and a network supporting n77 after expansion, corresponding to a spectrum range of 3450 to 3550MHz, which may also be referred to as a new network.

In one embodiment, a newly defined Network Signaling (NS) value (value) is adopted for the a country spread spectrum, the new Network prevents the legacy terminal from accessing the Network by issuing a new NS value through a System Information Block (SIB1, System Information Block) to inform the terminal that the Network supports spread spectrum, and new terminal capabilities are defined for the new terminal to indicate that the terminal is the new terminal.

In one embodiment, the NS value is originally used to indicate a regional regulation performed by the network, and the network performs Power control on the terminal according to an Additional Maximum Power Reduction (AMPR) corresponding to the NS value. Using NS value to indicate the spectrum range supported by the network, although legacy terminals can be prevented from camping on the network, the original purpose of NS value is violated, and different NS values need to be defined for different extended requirements and operators in different regions. If a new NS value is defined for the demand of the B country, a new NS value is defined if the spectrum of the united states is extended again.

As shown in fig. 3, in this embodiment, a method for sending network capability information is provided, where the method is performed by an access network device, and the method includes:

If the 4th bit of the IE freqbandwidth-v 17xx information field is set to "1", the network capability information indicates that the network is the new B network and the new C network, and the corresponding spectrum ranges are the spectrum ranges of the new B network and the new C network.

If the 3 rd bit and the 4th bit of the IE freqbandwidth-v 17xx information field are set to "1", the network capability information indicates that the network is the new B-net and the corresponding spectrum range is the spectrum range of the new B-net.

If bits 2 and 4 of the IE freqbandwidth-v 17xx information field are set to "1", the network capability information indicates that the network is the new C-net and the corresponding spectrum range is the spectrum range of the new C-net.

In one embodiment, different bits are used for mapping for different spectral ranges of a band.

In one embodiment, different countries using the same spectral range may be mapped with the same bits, and different countries using different spectral ranges may be mapped with different bits.

In one embodiment, the spectrum used in nation C is 3450-3550MHz, and after expansion, is 3450-. When the network only supports the spectral range 3700 to 3980MHz, the 1 st bit is set to "1", indicating that the network is a conventional a-network. When the network supports only the spectrum range 3450 to 3550MHz, the 2 nd bit is set to "1", indicating that the network is a new a network, or a legacy C network. When the network supports the spectral ranges 3450 to 3550MHz and 3700 to 3980MHz, the 1 st and 2 nd bits are set to "1", representing that the network is the new a-net.

For example, in the case of a liquid,

in one embodiment, the entries of the information fields of the SIB1 for carrying the network capability information are the same. The entry may correspond to "xx" in "v 17xx," illustratively for example:

in one embodiment, the second network capability information may be broadcasted through an IE freqbandransinglist information field in the system message, and the second network capability information is used to indicate information of an ARFCN corresponding to a frequency spectrum range supported by the network on the broadcasted frequency band and a network channel value, where the information of the ARFCN indicates a start number and an end number.

Wherein, the information domain carrying the first network capability information is indicated by a bit map mode; different bits of the bitmap are used to indicate different spectral value ranges, country codes and/or network types.

It should be noted that each bit (bit) of the IE freqbandwidth-v 17xx information field may indicate the range of the spectrum value, the country code and/or the network type supported by the network, respectively. Taking the n77 band as an example, please refer to table one again:

in table one, bit 0 is a reserved bit; bit 1 indicates the spectral value range 3700 to 3980MHz and the country code "a"; bit 2 indicates a spectral value range 3450 to 3550MHz and country codes "B" and "C"; bit 3 indicates a spectral value range 3450 to 3650MHz and a country code "C"; the 4th bit indicates a spectral value range 3650 to 3980MHz and country codes "B" and "C".

In one embodiment, the frequency spectrum used in nation C is 3450-3550MHz, and after expansion, 3450-3550MHz and 3650-3980MHz are used. When the network only supports the spectral range 3700 to 3980MHz, the 1 st bit is set to "1", indicating that the network is a conventional a-network. When the network supports only the spectrum range 3450 to 3550MHz, the 2 nd bit is set to "1" indicating that the network is a new a net, or a legacy C net. When the network supports the spectral ranges 3450 to 3550MHz and 3700 to 3980MHz, the 1 st and 2 nd bits are set to "1", representing that the network is the new a-net.
