[Technical Field]

[0001] TECHNICAL FIELD The present invention relates to the field of communication technology, and in particular to a method for reporting terminal capabilities, a method for processing terminal capabilities, a terminal device, a network device, and a storage medium. [Background technology]

[0002] As the fifth-generation wireless communication network New Radio (5G New Radio, NR) is widely deployed, the industrial application fields of 5G are also becoming increasingly widespread. 5G introduces two network architectures, namely, standalone (SA) mode and non-standalone (NSA) mode, and the frequency band capability sets supported by corresponding terminals are becoming increasingly complex. 3GPP has made great efforts to achieve as-needed reporting as possible. However, due to the large number of frequency bands, the current mechanism, especially in the case of NSA, supports too many terminal capability sets. Therefore, according to the conventional limitations, the terminal equipment can only report a portion of the frequency band combinations to the network. Therefore, the terminal equipment's capability report cannot include all supported frequency band combinations. As a result, the network equipment may mistakenly determine that the terminal equipment does not support the current frequency band combination, resulting in failure to add a communication cell with the frequency band corresponding to the terminal equipment.

[0011] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments, and all other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without any creative work fall within the protection scope of the embodiments of the present invention.

[0012] The flowcharts shown in the drawings are illustrative and do not necessarily include all content or operations / steps, nor do they necessarily have to be performed in the order described. For example, some operations / steps may be separated, combined, or partially combined, and the order in which they are actually performed may vary depending on the actual situation.

[0013] It should be understood that the terminology used in the description of the embodiments of the present invention is for the purpose of describing particular embodiments only, and is not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, the singular forms "a," "one," and "the" are intended to include the plural forms unless the context clearly dictates otherwise.

[0014] First, in order to better understand the solution of the embodiments of the present application, the following first describes the related art and existing technical problems.

[0015] 5G will launch two network architectures, specifically including Standalone Access (SA) mode and Non-Standalone Access (NSA) mode, and the frequency band support capabilities of corresponding terminal equipment will also become increasingly complex. 3GPP aims to achieve reporting as needed as possible, but due to the large number of frequency bands, according to the current mechanism, especially in the case of NSA, actual tests have found that due to the large number of frequency band combinations, terminals can only report part of the frequency band combinations to network equipment according to the traditional limitations, which will cause misunderstandings on the network side and result in the terminal equipment not adding 5G communication cells.

[0016] For example, a terminal device may support LTE B1 / 2 / 3 / 4 / 5 / 7 / 8 / 38 / 39 / 40 / 41 and NR N1 / 2 / 3 / 5 / 7 / 8 / 78 / 79 / ..., etc. For NSA, when the terminal device reports its LTE frequency band combination capabilities, the number of combinations may exceed the limit of the current protocol. For example, the current protocol limits the terminal device to independently determine which combination to report if the number of combinations exceeds 128, thereby ensuring that the number does not exceed 128. Because there are so many supported frequency band combinations, the terminal device may not report the NSA frequency band combination desired by the network equipment. As a result, the network equipment may believe that the terminal does not support the current NSA combination and may not add a 5G cell to the terminal. Currently, only manual frequency band locking methods are available, which forcibly remove some frequency band capabilities so that the terminal can register with the current NSA network. However, this method does not fundamentally solve the problem.

[0017] The embodiments of the present invention provide a terminal capability processing method, a terminal capability reporting method, a network device, a terminal device, and a storage medium, where the terminal capability processing method can be applied to a network device, so as to accurately determine whether the terminal device supports a current frequency band combination, and accurately add a communication cell of a frequency band corresponding to the terminal device.

[0018] As shown in Figure 1, Figure 1 is a flowchart of a terminal capability processing method according to an embodiment of the present invention, which can accurately determine whether a terminal device supports a current frequency band combination, and accurately add a communication cell of a frequency band corresponding to the terminal device, and the network device can be a base station, a gateway, etc.

[0019] As shown in FIG. 1, the terminal capability processing method may include steps S101 to S102.

[0020] Step S101: Send a capability query command to a terminal device, and the terminal device generates terminal capability information according to the capability query command, where the terminal capability information includes a frequency band capability set and identification information, and the identification information is used to indicate whether the terminal device has an excess frequency band capability set.

[0021] The capability query command is generated by a network device and is used to instruct a terminal device to query its supported frequency band capability set and generate corresponding terminal capability information. The terminal capability information includes a frequency band capability set and identification information. The frequency band capability set may be an NSA frequency band set. The NSA frequency band set is specifically composed of frequency band information of a first network and frequency band information of a second network, and may be composed of a combination of one frequency band corresponding to a 4G network and one frequency band corresponding to a 5G network.

[0022] Illustratively, the frequency band capability set may include NSA frequency band sets such as B1+N78, B1+N41, B1+N1, B7+N78, and B7+N41.

[0023] Specifically, the identification information is used to indicate whether the terminal equipment has an excess frequency band capability set, that is, after the terminal equipment has reported a frequency band capability set once or multiple times, it can indicate whether the terminal equipment has a frequency band capability set that has not yet been reported.

[0024] For example, the identification information may indicate that the terminal equipment has an excess frequency band capability set by an identification bit of '1', and the identification information may indicate that the terminal equipment does not have an excess frequency band capability set by an identification bit of '0'.

[0025] However, in order to accurately add a communication cell of a frequency band corresponding to a terminal device, the network equipment can be pre-configured to send a capability query command to the terminal device. For example, when the network equipment needs to determine whether the terminal device supports the current frequency band combination, the network equipment is configured to generate and send a capability query command to the corresponding terminal device, so that the terminal device generates terminal capability information based on the capability query command.

[0026] Step S102: when receiving the terminal capability information and detecting that the frequency band capability set does not include a target frequency band combination, perform a target frequency band query or target frequency band setting for the terminal device based on the identification information, and determine whether the terminal device supports the target frequency band combination, where the target frequency band combination includes target frequency band information of a first network and target frequency band information of a second network.

[0027] The target frequency band combination is a frequency band combination that a network device needs to determine whether it is supported by the terminal device, and specifically includes target frequency band information of a first network and target frequency band information of a second network. The first network may be 4G, 5G, or 6G, etc., and the second network may be 4G, 5G, or 6G, etc., but the types of the first network and the second network in the target frequency band combination are different, i.e., if the first network is 4G, the second network can only be 5G or 6G.

[0028] For example, the frequency band information of the first network may be frequency bands such as B1, B3, and B7, and the frequency band information of the second network may be frequency bands such as N78, N41, and N7. Note that the frequency band information of the first network may be frequency bands such as N78, N41, and N7, and the frequency band information of the second network may be frequency bands such as B1, B3, and B7, and there is no particular limitation here.

[0029] In an embodiment of the present invention, the network device sends a capability query command to the terminal device, so that the terminal device generates terminal capability information based on the capability query command and sends it to the network device. If the network device detects that the frequency band capability set does not include the target frequency band combination, it performs a target frequency band query on the terminal device based on the identification information to determine whether the terminal device supports the target frequency band combination, thereby accurately determining whether the terminal device supports the current frequency band combination and accurately adding a communication cell of the frequency band corresponding to the terminal device.

[0030] In some embodiments, the network device receives the terminal capability information, detects whether the frequency band capability set includes a target frequency band combination, and determines that the terminal device supports the target frequency band combination if it detects that the frequency band capability set includes the target frequency band combination, i.e., the network device can determine that the terminal device supports the target frequency band combination, thereby quickly determining that the terminal device supports the current frequency band combination.

[0031] Illustratively, the network device receives terminal capability information sent from a terminal device, and the terminal capability information includes a frequency band capability set, which includes NSA frequency band sets such as B1+N78, B1+N41, B1+N1, B7+N78, and B7+N41. If the target frequency band combination is B1+N78, it can determine that the frequency band capability set includes the target frequency band combination, and determine that the terminal device supports the target frequency band combination.

[0032] In some embodiments, the network device receives the terminal capability information, detects whether the frequency band capability set includes a target frequency band combination, and if it detects that the frequency band capability set does not include the target frequency band combination and the identification information indicates that the terminal device has an excess frequency band capability set, sends a terminal excess capability query command to the terminal device, and the terminal device determines terminal excess capability information based on the terminal excess capability query command, the terminal excess capability information including an excess frequency band capability set and updated identification information, and if it receives the terminal excess capability information and detects that the excess frequency band capability set does not include the target frequency band combination, performs a target frequency band query on the terminal device based on the updated identification information until the updated identification information indicates that the terminal device has no excess capability, to determine whether the terminal device supports the target frequency band combination, thereby allowing the network device to accurately and completely obtain the frequency band capability set of the terminal device, thereby accurately determining whether the terminal device supports the current frequency band combination, and accurately adding a communication cell of the frequency band corresponding to the terminal device.

[0033] However, the terminal excess capability query command is generated by a network device and is used to instruct a terminal device to query an unreported frequency band capability set supported by the terminal device and generate corresponding terminal excess capability information. The terminal excess capability information may include an excess frequency band capability set and updated identification information, and the excess frequency band capability set may be an NSA frequency band set after the terminal device screens the excess frequency band capability set.

[0034] Specifically, the network device receives the terminal excess capability information, detects whether the excess frequency band capability set includes the target frequency band combination, and determines that the terminal device supports the target frequency band combination if it detects that the excess frequency band capability set includes the target frequency band combination, i.e., the network device can determine that the terminal device supports the target frequency band combination, thereby quickly determining that the terminal device supports the current frequency band combination.

[0035] Specifically, when it is detected that the surplus frequency band capability set does not include the target frequency band combination, if the updated identification information indicates that the terminal device still has a surplus frequency band capability set, the network device will continue to generate terminal surplus capability query commands to acquire surplus frequency band capability sets until the updated identification information indicates that the terminal device still has a surplus frequency band capability set, in other words, until the updated identification information indicates that the terminal device has no surplus capability.

[0036] In some embodiments, the terminal capability information is received, and the frequency band capability set is detected to include a target frequency band combination. If the frequency band capability set is not included and the identification information indicates that the terminal device has an excess frequency band capability set, the terminal device sends a target frequency band setting command to the terminal device, and the terminal device performs target frequency band setting based on the target frequency band setting command to generate a target frequency band setting result, receives the target frequency band setting result, and determines whether the terminal device supports the target frequency band combination based on the target frequency band setting result. This can reduce the time for network registration, thereby improving the efficiency of the network device determining the frequency band combination supported by the terminal device, accurately determining whether the terminal device supports the current frequency band combination, and accurately adding a communication cell of the frequency band corresponding to the terminal device.

[0037] However, the target frequency band setting command includes network setting information corresponding to the target frequency band combination and is used to directly add the target frequency band combination corresponding to the terminal device to determine whether the terminal device supports the target frequency band combination, and the target frequency band setting result is used to indicate whether the terminal device supports the target frequency band combination.

[0038] Illustratively, a network device receives terminal capability information transmitted from a terminal device, the terminal capability information including a frequency band capability set, the frequency band capability set including NSA frequency band sets such as B1+N78, B1+N41, B1+N1, B7+N78, and B7+N41. If the target frequency band combination is B1+N79, it can determine that the frequency band capability set does not include the target frequency band combination, and it can determine that the terminal device does not support the target frequency band combination. At this time, if the identification information indicates that the terminal device has an excess frequency band capability set, the network device can send a target frequency band setting command corresponding to the target frequency band combination B1+N79 to the terminal device, causing the terminal device to directly set the target frequency band combination B1+N79, thereby generating a target frequency band setting result, receive the target frequency band setting result transmitted from the terminal device, and determine whether the terminal device supports the target frequency band combination based on the target frequency band setting result.

[0039] As shown in Figure 2, Figure 2 is a flowchart of a terminal capability reporting method according to an embodiment of the present invention, which can accurately determine whether a terminal device supports a current frequency band combination and accurately add communication cells of frequency bands corresponding to the terminal device, and the terminal capability reporting method can be specifically applied to terminal devices, such as smartphones, tablet computers, laptops, desktop computers, smart speakers, smart watches, etc., but is not limited thereto.

[0040] As shown in FIG. 2, the terminal capability processing method includes steps S201 to S202.

[0041] Step S201: obtain a capability query command sent from a network device, and determine terminal capability information according to the capability query command, where the terminal capability information includes a frequency band capability set and identification information, and the identification information is used to indicate whether the terminal device has an excess frequency band capability set.

[0042] The capability query command is generated by a network device and is used to instruct a terminal device to query its supported frequency band capability set and generate corresponding terminal capability information. The terminal capability information includes a frequency band capability set and identification information. The frequency band capability set may be an NSA frequency band set. The NSA frequency band set is specifically composed of frequency band information of a first network and frequency band information of a second network, and may be composed of a combination of one frequency band corresponding to a 4G network and one frequency band corresponding to a 5G network.

[0043] Illustratively, the frequency band capability set may include NSA frequency band sets such as B1+N78, B1+N41, B1+N1, B7+N78, and B7+N41.

[0044] Specifically, the identification information is used to indicate whether the terminal equipment has an excess frequency band capability set, that is, after the terminal equipment has reported a frequency band capability set once or multiple times, it can indicate whether the terminal equipment has a frequency band capability set that has not yet been reported.

[0045] For example, the identification information may indicate that the terminal equipment has an excess frequency band capability set by an identification bit of '1', and the identification information may indicate that the terminal equipment does not have an excess frequency band capability set by an identification bit of '0'.

[0046] In some embodiments, the capability query command includes target frequency band information of a first network, and the network device determines and combines frequency band information of the first network and frequency band information of the second network supported by the terminal device based on the capability query command to obtain a terminal capability set, determines the number of frequency band combinations in the terminal capability set, generates identification information based on the number of frequency band combinations and the number of predetermined frequency band combinations, and screens the terminal capability set based on the target frequency band information of the first network based on a predetermined priority policy to obtain the frequency band capability set, thereby allowing more relevant frequency band combinations to be reported preferentially and improving the efficiency of the network device in determining whether the terminal device supports the target frequency band combination.

[0047] However, the target frequency band information of the first network may be frequency band information of the first network in the target frequency band combination, or if the target frequency band combination is B1+N79, the target frequency band information of the first network may be B1 or N79, and the number of the predetermined frequency band combinations may be the number of frequency band combinations limited by the protocol when reporting terminal capabilities, for example, 128.

[0048] Specifically, when receiving a capability query command, the terminal device first queries the frequency band information of the first network and the frequency band information of the second network supported by the terminal device, combines them to obtain a terminal capability set, determines the number of frequency band combinations in the terminal capability set, determines whether the number of frequency band combinations exceeds a predetermined number of frequency band combinations, generates identification information to indicate that the terminal device has an excess frequency band capability set if the number of frequency band combinations exceeds the predetermined number of frequency band combinations, and generates identification information to indicate that the terminal device does not have an excess frequency band capability set if the number of frequency band combinations does not exceed the predetermined number of frequency band combinations.

[0049] For example, the number of frequency band combinations in the terminal capability set is determined, and it is determined whether the number of frequency band combinations exceeds a predetermined number of frequency band combinations. If the number of frequency band combinations exceeds the predetermined number of frequency band combinations, identification information with an identification bit of '1', i.e., identification information indicating that the terminal device has an excess frequency band capability set, is generated. If the number of frequency band combinations does not exceed the predetermined number of frequency band combinations, identification information with an identification bit of '0', i.e., identification information indicating that the terminal device does not have an excess frequency band capability set.

[0050] In some embodiments, a first sorting is performed on the frequency band combinations in the terminal capability set based on the target frequency band information of the first network and the geographical location of the terminal device to obtain a first sorted terminal capability set, a second sorting is performed on the first sorted terminal capability set based on the priority of the frequency band information of the second network to obtain a second sorted terminal capability set, and the second sorted terminal capability set is screened based on the number of the predetermined frequency band combinations to obtain a frequency band capability set. This allows highly relevant frequency band combinations to be reported preferentially, improving the efficiency of the network device in determining whether the terminal device supports the target frequency band combination.

[0051] For example, when the frequency band information of the first network among the frequency band combinations in the terminal capability set includes frequency band B1, frequency band B3, and frequency band B7, and the target frequency band information of the first network is B3, the priority of all frequency band combinations whose frequency band information is B3 can be set to the highest; when the geographical location of the terminal equipment is Asia, frequency band B7 is mainly used in the European region, and frequency band B1 is mainly used in the Asian region, so the priority of frequency band B3 is higher than frequency band B1 and the priority of frequency band B1 is higher than frequency band B7, thereby obtaining the terminal capability set after initial sorting. If the frequency band information of the second network among the frequency band combinations in the terminal capability set includes frequency band N78, frequency band N41, frequency band N1, and frequency band N28, the popularity degree is N78>N41>N1>N28, so the priority of frequency band N78 may be considered to be greater than frequency band N41, frequency band N1, and frequency band N28, thereby obtaining a terminal capability set after the second sorting, and screening the terminal capability set after the second sorting based on the number of the predetermined frequency band combinations to obtain a frequency band capability set.

[0052] For example, if the number of predetermined frequency band combinations is four, then the terminal capability set of the terminal equipment includes B1+N78, B1+N41, B1+N1, B1+N28, B7+N78, B7+N41, B7+N1, B7+N28, B3+N78, B3+N41, B3+N1, B3+N28, B3+N79, and B3+N7. If the target frequency band information of the first network is B3, and the priority of frequency band N78 is higher than frequency band N41, frequency band N1, and frequency band N28, then the frequency band capability set includes B3+N78, B3+N41, B3+N1, and B3+N28.

[0053] For example, if the number of predetermined frequency band combinations is 8, then the terminal capability set of the terminal equipment includes B1+N78, B1+N41, B1+N1, B1+N28, B7+N78, B7+N41, B7+N1, B7+N28, B3+N78, B3+N41, B3+N1, B3+N28, B3+N79 and B3+N7. If the target frequency band information of the first network is B3, it will preferentially report B3+N78, B3+N41, B3+N1, B3+N28, B3+N79 and B3+N7. At this time, two vacant seats remain. If the terminal equipment is in China, the priority of B1 is greater than that of B7, and the priority of frequency band N78 is greater than frequency band N41, frequency band N1 and frequency band N28. Therefore, it will preferentially report B1+N78 and B1+N41 for the remaining two vacant seats. At this time, the frequency band capability set includes B3+N78, B3+N41, B3+N1, B3+N28, B3+N79, B3+N7, B1+N78 and B1+N41.

[0054] In some embodiments, after the step of screening the terminal capability set based on the target frequency band information of the first network and obtaining a frequency band capability set according to a predetermined priority policy, frequency band combinations in the frequency band capability set are removed from the terminal capability set to obtain an excess frequency band capability set, which makes it easier for subsequent network devices to obtain the full terminal capability set of the terminal device.

[0055] However, the surplus frequency band capability sets are composed of frequency band capability sets that have not been reported. By removing the reported frequency band capability sets, the frequency band capability sets can be accurately updated, and the repeated uploading of uploaded frequency band capability sets, which causes resource waste, can be avoided.

[0056] Step S202: Send the terminal capability information to the network device. If the network device detects that the frequency band capability set does not include a target frequency band combination, it performs a target frequency band query or target frequency band setting for the terminal device based on the identification information to determine whether the terminal device supports the target frequency band combination, where the target frequency band combination includes target frequency band information of a first network and target frequency band information of a second network.

[0057] The target frequency band combination is a frequency band combination that a network device needs to determine whether it is supported by the terminal device, and specifically includes target frequency band information of a first network and target frequency band information of a second network. The first network may be 4G, 5G, or 6G, etc., and the second network may be 4G, 5G, or 6G, etc., but the types of the first network and the second network are different, i.e., if the first network is 4G, the second network can only be 5G or 6G.

[0058] For example, the frequency band information of the first network may be frequency bands such as B1, B3, and B7, and the frequency band information of the second network may be frequency bands such as N78, N41, and N7. Note that the frequency band information of the first network may be frequency bands such as N78, N41, and N7, and the frequency band information of the second network may be frequency bands such as B1, B3, and B7, and there is no particular limitation here.

[0059] However, if the network device detects that the frequency band capability set does not include the target frequency band combination, it queries the terminal device for a target frequency band based on the identification information to determine whether the terminal device supports the target frequency band combination. The specific steps are detailed in step S102.

[0060] In some embodiments, a terminal excess capability query command sent from a network device is received, and the terminal excess capability query command is generated when the network device detects that the frequency band capability set does not include a target frequency band combination and the identification information indicates that the terminal device has excess capability; the network device determines the number of frequency band combinations in the excess frequency band capability set based on the terminal excess capability query command; updates the identification information based on the number of frequency band combinations and a number of predetermined frequency band combinations; and screens the excess frequency band capability set based on the number of predetermined frequency band combinations to obtain a target excess frequency band capability set.

[0061] However, the surplus frequency band capability set is a frequency band capability set that has not been reported, and the target surplus frequency band capability set is a frequency band capability set that is waiting to be reported after screening the surplus frequency band capability set.

[0062] For example, first determine the number of frequency band combinations in the excess frequency band capability set; if the number of frequency band combinations in the excess frequency band capability set exceeds a predetermined number of frequency band combinations, update the identification bit of the identification information to "1"; screen the excess frequency band capability set based on the predetermined number of frequency band combinations to obtain a target excess frequency band capability set; if the number of frequency band combinations in the excess frequency band capability set does not exceed the predetermined number of frequency band combinations, update the identification bit of the identification information to "0"; there is no need to screen the excess frequency band capability set; and directly report all frequency band capability sets in the excess frequency band capability set.

[0063] It should be noted that the specific screening steps for obtaining the target surplus frequency band capability set are similar to the specific screening steps for obtaining the above frequency band capability set.

[0064] In some embodiments, a target frequency band setting command sent from a network device is received, and the target frequency band setting command is generated when the network device detects that the frequency band capability set does not include a target frequency band combination and the identification information indicates that the terminal device has excess capacity, and an analysis process is performed on the target frequency band setting command to obtain target frequency band information of the second network, and the target frequency band information of the second network is set in the terminal device, thereby generating a target frequency band setting result.

[0065] However, the target frequency band information of the second network may be frequency band information of the second network in the target frequency band combination, for example, when the target frequency band combination is B1+N79 and the frequency band information of the first network is B1, the target frequency band information of the second network is N79. The target frequency band setting result is used to indicate whether the terminal device supports the target frequency band combination.

[0066] Specifically, an analysis process can be performed on the target frequency band setting command sent from the network device, thereby obtaining target frequency band information of the second network, directly setting the target frequency band information of the second network in the terminal device, and determining whether the terminal device supports the target frequency band combination, thereby generating a target frequency band setting result.
