Description
Technical Field
The present invention relates to the field of frequency band bandwidth negotiation technologies, and in particular, to a frequency band bandwidth negotiation method, apparatus, network server, and storage medium.
Background
With the vigorous development of the 5G technology, the 5G operable frequency band resources are further developed and used in different countries. For example, in the GSM (Global System for Mobile Communication) era, the frequency Band used by people is only a part of the bandwidth of Band 1/2/5/8. In the era of WCDMA/TD-SCDMA, people have more demands on bandwidth, and at this time, TDD of WCDMA and FDD of TD-SCDMA are allocated more frequency bands. By the LTE (Long Term Evolution) era, the frequency band is further expanded. In the 5G era, people have increasingly demanded bandwidth, and the frequency band of millimeter waves is also incorporated into the specification.
The increase in the medium frequency band and bandwidth of the specification also requires the configuration of the antenna technology. In some cases, the antennas of handsets do not support the full bandwidth of some frequency bands for several reasons.
Taking Band 41 of 3GPP TS 36.101 protocol specification as an example:
band 41 is used for LTE TDD and has a bandwidth in the range of 2496MHz-2690MHz, i.e. a bandwidth of 196 MHz. In the antenna device in the market, the device capable of processing the whole bandwidth of Band 41 is expensive, and considering that the requirements of most operators on Band 41 are limited to some parts thereof, for example, the Band 41 resource of china mobile is 160MHz in total from 2515MHz to 2675MHz, so if an OEM manufacturer makes a china mobile operator, Band 41 may not support the full Band, and only 2515MHz to 2675MHz needs to be supported.
For the supporting situation of the frequency band, the handset and the network only negotiate the frequency band, but do not negotiate a part of the bandwidth of the frequency band. So the handset supporting part of Band 41 in the above example has two problems:
1. the mobile phone roams abroad to a mobile phone supporting Band 41, but when the range is not completely within the 2515MHz-2675MHz range of China mobile, the mobile phone has the problem that the Band 41 can not be accessed.
2. A product from many companies now is globally customized, and that product will be used to screen Band 41 for frequencies in the remaining Band 41 that are not in the 2515MHz-2675MHz range, since the handset cannot access Band 41. This reduces the number of bands that can be selectively accessed for the handset, and requires the handset manufacturer to customize the operation according to the spectrum support of the operator.
Thus, there is a need for improvements and enhancements in the art.

With the vigorous development of the 5G technology, the 5G operable frequency band resources are further developed and used in different countries. For example, in the GSM (Global System for Mobile Communication) era, the frequency Band used by people is only a part of the bandwidth of Band 1/2/5/8. In the era of WCDMA/TD-SCDMA, people have more demands on bandwidth, and at this time, TDD of WCDMA and FDD of TD-SCDMA are allocated more frequency bands. By the LTE (Long Term Evolution) era, the frequency band is further expanded. In the 5G era, people have increasingly demanded bandwidth, and the frequency band of millimeter waves is also incorporated into the specification.
The increase in the medium frequency band and bandwidth of the specification also requires the configuration of the antenna technology. In some cases, the antennas of handsets do not support the full bandwidth of some frequency bands for several reasons.
Taking Band 41 of 3GPP TS 36.101 protocol specification as an example:
band 41 is used for LTE TDD and has a bandwidth in the range of 2496MHz-2690MHz, i.e. a bandwidth of 196 MHz. In the antenna device in the market, the device capable of processing the whole bandwidth of Band 41 is expensive, and considering that the requirements of most operators on Band 41 are limited to some parts thereof, for example, the Band 41 resource of china mobile is 160MHz in total from 2515MHz to 2675MHz, so if an OEM manufacturer makes a china mobile operator, Band 41 may not support the full Band, and only 2515MHz to 2675MHz needs to be supported.
For the supporting situation of the frequency band, the handset and the network only negotiate the frequency band, but do not negotiate a part of the bandwidth of the frequency band. So the handset supporting part of Band 41 in the above example has two problems:
1. the mobile phone roams abroad to a mobile phone supporting Band 41, but when the range is not completely within the 2515MHz-2675MHz range of China mobile, the mobile phone has the problem that the Band 41 can not be accessed.
2. A product from many companies now is globally customized, and that product will be used to screen Band 41 for frequencies in the remaining Band 41 that are not in the 2515MHz-2675MHz range, since the handset cannot access Band 41. This reduces the number of bands that can be selectively accessed for the handset, and requires the handset manufacturer to customize the operation according to the spectrum support of the operator.
In order to solve the problems in the prior art, the present embodiment provides a frequency band bandwidth negotiation method, where the method obtains network function information of a user terminal; determining bandwidth frequency band information supported by the user terminal according to the network function information; and carrying out frequency band negotiation according to the bandwidth frequency band information. The invention can avoid the situation that the user terminal is unavailable in some networks due to the mismatching of the bandwidth frequency bands of the network server and the user terminal. The invention can avoid the situation that the user terminal is not available in some networks due to the mismatching of the Network (namely, the Network server) and the Band bandwidth frequency Band information of the user terminal. The user terminal is unavailable, which has a large influence on the user, for example, the user cannot access the network and cannot use the network function; inability to make a call, etc.
Exemplary method
The present embodiment is applied to a network server, as shown in fig. 1, the method includes the following steps:
and step S100, acquiring network function information of the user terminal.
In this embodiment, the network server obtains the network function information of the user terminal, where the response in the network function information is the bandwidth and frequency band information supported by the user terminal in this embodiment. Specifically, the present embodiment sends function acquisition request information to the user terminal; and then acquiring the network function information according to the function acquisition request information. In this embodiment, after receiving the function acquisition request information, the user terminal may acquire the network function information according to the function acquisition request information. Therefore, in this embodiment, the user terminal first needs to connect with the network server, so that the user terminal can receive the function acquisition request information sent by the user terminal. Specifically, the network server in this embodiment sends the capability information (i.e., the function acquisition request information) to the user terminal, and after receiving the capability information, the user terminal sends the capability information (i.e., the network function information). In this embodiment, the user terminal may be an intelligent terminal device such as a mobile phone, a computer, and a tablet computer, and the intelligent terminal device has a networking function so as to be connected to a network server.
Step S200, according to the network function information, determining the bandwidth frequency range information supported by the user terminal.
After the user terminal receives the function acquisition request information sent by the network server, the user terminal in this embodiment may send the network function information according to the function acquisition request information. The network server can determine the bandwidth frequency band information supported by the user terminal according to the network function information.
In specific implementation, the embodiment of the invention firstly obtains the bandwidth list information in the network function information; and then determining the bandwidth frequency band information supported by the user terminal according to the bandwidth list information. In this embodiment, the present embodiment may determine, according to the bandwidth list information, authority information of each bandwidth frequency band in the bandwidth list information; and then determining the bandwidth frequency band information supported by the user terminal according to the authority information. That is to say, in this embodiment, the network function information carries an option item, where the option item represents the authority information of the bandwidth frequency band information, so that it can be determined whether each bandwidth frequency band information in the bandwidth list information of the user terminal has an authority according to the authority information, and therefore, if the authority exists, it indicates that the user terminal supports the bandwidth frequency band information; and if the user terminal does not have the authority, the user terminal does not support the bandwidth frequency band information.
And step S300, carrying out frequency band negotiation according to the bandwidth frequency band information.
After obtaining the bandwidth frequency band information (i.e., the bandwidth frequency band information supported by the user terminal) in this embodiment, the embodiment may perform frequency band negotiation according to the bandwidth frequency band information. Specifically, the embodiment determines matching information between the bandwidth frequency band information and a network server according to the bandwidth frequency band information; and then carrying out frequency band negotiation according to the matching information. In this embodiment, the matching information refers to a matching status between the user terminal and the network server. And if the bandwidth frequency band information is matched with the network server, maintaining the original bandwidth configuration. And if the bandwidth frequency band information is not matched with the network server, the function acquisition request information is sent to the user terminal again after unmatched bandwidth segments are discharged. In another implementation, if the bandwidth frequency band information is not matched with the network server, the unmatched bandwidth frequency band information is avoided being used during network allocation.
In specific implementation, if the Band bandwidth frequency Band information of the user terminal in the capability information (i.e., Network function information) received by the Network (i.e., Network server) is not matched with the Network (i.e., Network server), the embodiment performs two cases:
1. under the LTE, if there is mismatch between Band bandwidth and frequency Band information, the Network (i.e., the Network server) re-issues the capability acquisition request message, which can remove the Band bandwidth and frequency Band information with mismatched bandwidth information, and the user terminal re-feeds back the capability information (i.e., the Network function information) to the Network (i.e., the Network server).
2. Since the NR (next radio) case is that the base station dynamically allocates bandwidth (BWP technology) to the handset, in the NR case, if there is a mismatch of Band bandwidth information, two cases are subdivided:
if the intersection of the Band bandwidth of the base station and the Band bandwidth of the user terminal is considered to be insufficient to support the Network use of the mobile phone by the Network (namely, the Network server), the Network (namely, the Network server) performs the same processing scheme as the LTE, and after the Band is eliminated, the Network (namely, the Network server) re-issues the capacity acquisition request (namely, the function acquisition request information).
If the intersection of the Band bandwidth frequency Band information of the base station and the Band bandwidth of the user terminal is considered to support the Network use of the mobile phone, the Network (i.e. the Network server) records the bandwidth frequency Band information of the user terminal, and avoids scheduling a frequency Band which is not supported by the user terminal during Network resource scheduling.
To sum up, the embodiment first obtains the network function information of the ue; determining bandwidth frequency band information supported by the user terminal according to the network function information; and carrying out frequency band negotiation according to the bandwidth frequency band information. The embodiment can avoid the situation that the user terminal is unavailable in some networks due to the fact that the bandwidth frequency bands of the network server and the user terminal are not matched. The invention can avoid the situation that the user terminal is not available in some networks due to the mismatching of the Network (namely, the Network server) and the Band bandwidth frequency Band information of the user terminal. The user terminal is unavailable, which has a large influence on the user, for example, the user cannot access the network and cannot use the network function; inability to make a call, etc.

Specifically, the present embodiment sends function acquisition request information to the user terminal; and then acquiring the network function information according to the function acquisition request information. In this embodiment, after receiving the function acquisition request information, the user terminal may acquire the network function information according to the function acquisition request information. Therefore, in this embodiment, the user terminal first needs to connect with the network server, so that the user terminal can receive the function acquisition request information sent by the user terminal. Specifically, the network server in this embodiment sends the capability information (i.e., the function acquisition request information) to the user terminal, and after receiving the capability information, the user terminal sends the capability information (i.e., the network function information).

The network server can determine the bandwidth frequency band information supported by the user terminal according to the network function information.
In specific implementation, the embodiment of the invention firstly obtains the bandwidth list information in the network function information; and then determining the bandwidth frequency band information supported by the user terminal according to the bandwidth list information. In this embodiment, the present embodiment may determine, according to the bandwidth list information, authority information of each bandwidth frequency band in the bandwidth list information; and then determining the bandwidth frequency band information supported by the user terminal according to the authority information. That is to say, in this embodiment, the network function information carries an option item, where the option item represents the authority information of the bandwidth frequency band information, so that it can be determined whether each bandwidth frequency band information in the bandwidth list information of the user terminal has an authority according to the authority information, and therefore, if the authority exists, it indicates that the user terminal supports the bandwidth frequency band information; and if the user terminal does not have the authority, the user terminal does not support the bandwidth frequency band information.

In one implementation manner, the frequency band negotiation unit includes:
and the network allocation control unit is used for avoiding using unmatched bandwidth frequency band information during network allocation if the bandwidth frequency band information is unmatched with the network server.

Specifically, the embodiment determines matching information between the bandwidth frequency band information and a network server according to the bandwidth frequency band information; and then carrying out frequency band negotiation according to the matching information. In this embodiment, the matching information refers to a matching status between the user terminal and the network server. And if the bandwidth frequency band information is matched with the network server, maintaining the original bandwidth configuration. And if the bandwidth frequency band information is not matched with the network server, the function acquisition request information is sent to the user terminal again after unmatched bandwidth segments are discharged.

In specific implementation, if the Band bandwidth frequency Band information of the user terminal in the capability information (i.e., Network function information) received by the Network (i.e., Network server) is not matched with the Network (i.e., Network server), the embodiment performs two cases:
1. under the LTE, if there is mismatch between Band bandwidth and frequency Band information, the Network (i.e., the Network server) re-issues the capability acquisition request message, which can remove the Band bandwidth and frequency Band information with mismatched bandwidth information, and the user terminal re-feeds back the capability information (i.e., the Network function information) to the Network (i.e., the Network server).
2. Since the NR (next radio) case is that the base station dynamically allocates bandwidth (BWP technology) to the handset, in the NR case, if there is a mismatch of Band bandwidth information, two cases are subdivided:
