Referring to fig. 1, a system architecture diagram of a terminal capability reporting system 10 in an embodiment of the present application is shown. The system 10 includes a terminal device 1 and a wireless network 2. The terminal apparatus 1 is communicatively connected to a wireless network 2. In this embodiment, the terminal device 1 may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) device, a Virtual Reality (VR) device, an Artificial Intelligence (AI) device, a wearable device, a vehicle-mounted device, a smart home device, and/or a city device, and the specific type of the terminal device 1 is not particularly limited in this embodiment. The wireless network 2 may be a Long Term Evolution (LTE) network, a 5G stand-alone (SA) network, a 5G Non-stand-alone (NSA) network, or an endec network.

The following describes specific contents of a method for reporting terminal capability according to an embodiment of the present application with reference to fig. 1. Referring to fig. 3, a flowchart of a method for reporting terminal capability is shown. The method for reporting the terminal capability specifically comprises the following steps.

In step S301, the wireless network 2 transmits a terminal Capability query command (UE Capability inquiry) to the terminal apparatus 1.

In step S302, the terminal apparatus 1 queries Capability Information (UE Capability Information) of the terminal apparatus 1 according to the terminal Capability query instruction, and transmits the queried Capability Information of the terminal apparatus 1 to the wireless network 2.

Referring to fig. 2, an application scenario diagram of the terminal capability reporting system 10 in an embodiment of the present application is shown. In this embodiment, the terminal apparatus 1 registers with the wireless network 2 when it is turned on and accesses the network. After receiving the registration request of the terminal device 1, the wireless network 2 transmits a terminal capability query instruction to the terminal device 1, and the terminal device 1 queries the capability information of the terminal device 1 according to the terminal capability query instruction and transmits the queried capability information of the terminal device 1 to the wireless network 2.

In this embodiment, the capability information of the terminal apparatus 1 includes CA combinations and frequency bands supported by the terminal apparatus 1. The terminal device 1 inquires about the CA combinations and frequency bands supported by the terminal device 1 according to the terminal capability inquiry instruction, and transmits the CA combinations and frequency bands supported by the terminal device 1 to the wireless network 2. The CA combination may be at least one of a CA combination of an LTE network, a CA combination of an SA network, and a CA combination of an endec network.

In this embodiment, the terminal capability query instruction includes request frequency band information. The terminal device 1 queries the CA combinations and frequency bands supported by the terminal device 1 according to the terminal capability query instruction, and includes: the terminal device 1 responds to the terminal capability query instruction, acquires the requested frequency band information from the terminal capability query instruction, queries the CA combination corresponding to the requested frequency band information according to the requested frequency band information, and determines the frequency band supported by the terminal device 1 according to the requested frequency band information.

All CA combinations supported by the terminal device 1 are specified in the 36.101 protocol. According to the 36.101 protocol, if the UE Capability infrastructure delivered by the wireless network 2 does not carry the Requested Frequency band information (Requested Frequency Bands), the terminal device 1 reports all the supported CA combinations. If the number of CA combinations supported by the terminal device 1 is greater than 128 groups, the terminal device 1 reports the CA combinations of the first 128 groups according to the screening sequence specified by the 36.101 protocol, and the CA combinations after the 128 groups cannot be reported. If the Requested Frequency Bands are carried in the UE Capability requests issued by the wireless network 2, the terminal device 1 reports all CA combinations related to the Requested Frequency band information. If the number of CA combinations supported by the terminal device 1 is greater than 128 groups, the terminal device 1 reports the CA combinations of the first 128 groups according to the screening sequence specified by the 36.101 protocol, and the CA combinations after the 128 groups cannot be reported.

The terminal capability reporting method of the present application is described below with a mobile phone as a terminal device 1, an LTE network as a wireless network 2, and a CA combination of the LTE network as a CA combination. And the LTE network sends a terminal capability query instruction to the mobile phone. If the terminal capability query instruction carries the requested frequency band information, the requested frequency band information includes a B1 frequency band and a B3 frequency band. The mobile phone acquires the B1 frequency band and the B3 frequency band from the terminal capability query instruction, and searches a CA combination relation table (see table one to table eight) according to the B1 frequency band and the B3 frequency band to determine all CA combinations corresponding to combinations of the B1 frequency band, the B3 frequency band, the B1 frequency band and the B3 frequency band. The CA combination relation table includes all CA combinations specified in the 36.101 protocol, and each CA combination corresponds to a frequency band combination. For example, the frequency band combination corresponding to the CA combination labeled CA _1 is frequency band 1, the frequency band combination corresponding to the CA combination labeled CA _3 is frequency band 3, the frequency band combination corresponding to the CA combination labeled CA _1-1 is frequency band 1, the frequency band combination corresponding to the CA combination labeled CA _1-3 is frequency band 1, frequency band 3, and the frequency band combination corresponding to the CA combination labeled CA _1-1-3 is frequency band 1, frequency band 3. For example, the cell phone searches the CA combination relation table according to the B1 frequency band and the B3 frequency band to determine that all CA combinations corresponding to the frequency bands combined by the B1 frequency band and the B3 frequency band are CA _1, CA _3, CA _1-1, and CA _ 3-3. And the mobile phone sends all searched CA combinations to the LTE network to complete the report of the terminal capability. If the terminal capability query instruction sent to the mobile phone by the LTE network does not carry the request frequency band information, the mobile phone responds to the terminal capability query instruction to search CA combinations corresponding to all frequency bands supported by the mobile phone from a CA combination relation table, and sends the searched CA combinations to the LTE network to finish the report of the terminal capability.

It should be noted that one CA combination in the CA combination relationship table may correspond to multiple combinations reported by the terminal capability. For example, for the CA combination CA _1-3, a plurality of combinations of reports are generated according to different primary cells, different bandwidths, and different numbers of downlink or uplink layers. For example, the CA combination CA _1-3 generates, according to different primary cells, different bandwidths, and different numbers of downlink or uplink layers, a CA combination in which the primary carrier is a B1 frequency band, the bandwidth is 20MHz, the number of downlink layers is 4, the frequency band of the secondary carrier is a B3 frequency band, the bandwidth is 20MHz, and the number of downlink layers is 2, and a CA combination in which the primary carrier is a B1 frequency band, the bandwidth is 20MHz, the number of downlink layers is 4, the frequency band of the secondary carrier is a B3 frequency band, the bandwidth is 40MHz, and the number of downlink layers is 2. When reporting the terminal capability to the LTE network, the mobile phone sends all CA combinations marked as CA _1-3 to the LTE network.

It should be noted that, because of the limitation of the size of the uplink signaling, the number of CA combinations that the mobile phone sends to the LTE network is limited, and according to the specification of the protocol 36.331 of the third Generation Partnership Project (3 GPP), the mobile phone should report as many supported CA combinations as possible, and the excessive CA combinations cannot be reported. However, due to the limitation of the uplink signaling size, the CA combination reported by the mobile phone to the LTE network is up to 128 CA combinations. If the number of the CA combinations queried by the mobile phone exceeds 128 CA combinations, only 128 CA combinations can be reported according to the specification of the 3GPP 36.331 protocol, and the excess CA combinations cannot be reported.

In order to report all found CA combinations, another method for reporting terminal capabilities is provided in the present application, so as to send all combinations found by the terminal apparatus 1 to the wireless network 2.

Please refer to fig. 4, which is a flowchart illustrating a method for reporting a terminal capability according to another embodiment of the present application. The method is applied in the terminal device 1. The method specifically comprises the following steps.

In step S401, the wireless network 2 transmits a terminal capability query instruction to the terminal apparatus 1.

In step S402, the terminal device 1 queries the capability information of the terminal device 1 according to the terminal capability query instruction, and transmits the queried capability information of the terminal device 1 to the wireless network 2.

In step S403, the wireless network 2 determines whether or not the CA combination in the capability information of the terminal apparatus 1 reaches the maximum number of combinations. If the CA combination in the capability information of the terminal apparatus 1 reaches the maximum number of combinations, step S504 is executed, and if the CA combination in the capability information of the terminal apparatus 1 does not reach the maximum number of combinations, the flow ends.

In this embodiment, if the CA combination in the capability information of the terminal apparatus 1 does not reach the maximum combination number, it indicates that the terminal apparatus 1 has reported all the terminal capabilities, and if the CA combination in the capability information of the terminal apparatus 1 reaches the maximum combination number, it indicates that the terminal apparatus 1 has not reported all the terminal capabilities. In this embodiment, the maximum number of combinations is the maximum number of CA combinations transmitted by the terminal apparatus 1 to the wireless network 2, which is specified by the 36.101 protocol, and the maximum number of combinations is 128.

Step S404, the wireless network 2 determines at least one frequency band combination to be queried according to the frequency bands supported by the terminal device 1, and generates at least one second terminal capability query instruction including the frequency band combination to be queried.

Step S405, sending the second terminal capability query instruction to the terminal apparatus 1.

Step S406 is to receive the CA combination obtained by the query of the frequency band combination to be queried according to each second terminal capability query instruction sent by the terminal device 1.

In the application, the wireless network 2 determines the frequency band combination to be queried according to the frequency bands supported by the terminal device 1, generates a second terminal capability query instruction comprising the frequency band combination to be queried, and queries the capability information of the terminal device 1 by sending the second terminal capability query instruction to the terminal device 1 for multiple times, so that the technical problem that all CA combinations in the terminal capability information cannot be reported to the wireless network 2 when the number of the CA combinations reported by the terminal device 2 exceeds the maximum combination number is solved.

In this embodiment, the wireless network 2 determines at least one frequency band combination to be queried according to the frequency bands supported by the terminal device 1, generates at least one second terminal capability query instruction including the frequency band combination to be queried, and sends the second terminal capability query instruction to the terminal device includes: determining a candidate CA combination according to the first terminal capability query instruction; grouping the candidate CA combinations according to the frequency band number of the frequency band supported by the terminal device 1 to obtain at least one CA combination frequency band group, wherein all CA combinations in each CA combination frequency band group have the same number of frequency bands; determining the frequency band combination to be queried of each CA combined frequency band group, generating at least one second terminal capability query instruction comprising the frequency band combination to be queried, and sending the at least one second terminal capability query instruction to the terminal device 1. Specifically, the method for reporting terminal capability provided in an embodiment of the present application includes the steps shown in fig. 5.

In step S501, the wireless network 2 transmits a first terminal capability query instruction to the terminal apparatus 1.

In step S502, the terminal device 1 determines whether the first terminal capability query instruction includes the request frequency band information. If the first terminal capability query instruction includes the requested frequency band information, step S503 is executed, otherwise, if the first terminal capability query instruction does not include the requested frequency band information, step S504 is executed.

Step S503, in response to the first terminal capability query instruction, the terminal device 1 acquires the requested frequency band information from the first terminal capability query instruction, queries the terminal capability information corresponding to the requested frequency band information according to the requested frequency band information, and sends the terminal capability information to the wireless network 2, where the terminal capability information includes the CA combination and the frequency bands supported by the terminal device 1. Step S505 is executed after step S503 is executed.

In this embodiment, querying, according to the request frequency band information, the terminal capability information corresponding to the request frequency band information includes: and inquiring the CA combination corresponding to the request frequency band information according to the request frequency band information. The method for querying the CA combination corresponding to the requested frequency band information according to the requested frequency band information refers to the above description, and is not described in detail here.

In step S504, the terminal device 1 responds to the first terminal capability query instruction, queries the terminal capability information of the terminal device 1, and sends the terminal capability information to the wireless network 2. After step S504 is executed, step S505 is executed.

In this embodiment, querying the terminal capability information of the terminal device 1 includes: all CA combinations supported by the terminal apparatus 1 are queried. In this embodiment, the method for querying all CA combinations supported by the terminal apparatus 1 refers to the above description, and is not described in detail here.

In step S505, the wireless network 2 determines whether the CA combination of the terminal capability information reaches the maximum combination number. If the CA combination reaches the maximum number of combinations, step S506 is executed, and if the CA combination does not reach the maximum number of combinations, step S508 is executed.

Step S506, the wireless network 2 determines candidate CA combinations according to the first terminal capability query instruction, and groups the candidate CA combinations according to the number of frequency bands of the frequency bands supported by the terminal device 1 to obtain at least one CA combination frequency band group, where all CA combinations in each CA combination frequency band group have the same number of frequency bands.

In this embodiment, the determining, by the wireless network 2, the candidate CA combination according to the first terminal capability query instruction includes: judging whether the first terminal capability query instruction comprises request frequency band information or not; and if the first terminal capability query instruction does not include the request frequency band information, determining the candidate CA combination by the CA combination in the CA combination relation table (see table one to table eight). For example, the wireless network 2 queries, according to the first terminal capability query instruction that does not carry frequency band information, CA combinations of all frequency bands supported by the terminal apparatus 1, which are obtained by querying the CA combination relationship table, as the candidate CA combinations.

If the first terminal capability query instruction includes the requested frequency band information, determining the frequency band supported by the terminal device 1 according to the requested frequency band information, and determining all CA combinations with the frequency band supported by the terminal device 1 as the candidate CA combinations in the CA combination relation table according to the frequency band supported by the terminal device 1. For example, the wireless network 2 determines the frequency bands supported by the terminal device 1 as the frequency bands 1, 3, 5, 7, 19, and 40 according to the requested frequency band information carried in the first terminal capability query instruction, and the wireless network 2 queries the CA combination obtained by querying the CA combination relation table from the frequency bands 1, 3, 5, 7, 19, and 40 as the candidate CA combination.

In this embodiment, grouping, by the wireless network 2, the candidate CA combinations according to the number of frequency bands of the frequency band supported by the terminal device 1 to obtain at least one CA combination frequency band group includes: grouping the candidate CA combinations according to the frequency band number 1 to obtain a first CA combination frequency band group; grouping the candidate CA combinations according to the frequency band number 2 to obtain a second CA combination frequency band group; grouping the candidate CA combinations according to the frequency band number 3 to obtain a third CA combination frequency band group; grouping the candidate CA combinations according to the frequency band number 4 to obtain a fourth CA combination frequency band group; and grouping the candidate CA combinations according to the frequency band number 5 to obtain a fifth CA combination frequency band group. For example, the candidate CA combination may be a CA combination obtained by querying a CA combination relation table according to band 1, band 3, band 5, band 7, band 19, and band 40, see table nine, which shows a table of first CA combination frequency band grouping obtained by grouping the candidate CA combinations by the frequency band number 1. Referring to table ten, a table of grouping the frequency bands of the second CA combination obtained by grouping the candidate CA combinations according to the frequency band number 2 is shown. Referring to table eleven, a table of grouping the frequency bands of the third CA combination obtained by grouping the candidate CA combinations by the frequency band number 3 is shown. Referring to table twelve, a table of a fourth CA combination frequency band grouping obtained by grouping the candidate CA combinations by the frequency band number 4 is shown. Referring to table thirteen, a table of a fifth CA combination band grouping obtained by grouping the candidate CA combinations by the band number 5 is shown.

Step S507, the wireless network 2 determines the frequency band combination to be queried of each CA combined frequency band group, generates at least one second terminal capability query instruction including the frequency band combination to be queried, sends the at least one second terminal capability query instruction to the terminal device 1, and receives the CA combination obtained by querying the frequency band combination to be queried according to each second terminal capability query instruction sent by the terminal device 1.

In this embodiment, after receiving the second terminal capability query instruction sent by the wireless network 2, the terminal device 1 queries, according to the to-be-queried frequency band combination of each second terminal capability query instruction, to obtain a CA combination corresponding to the to-be-queried frequency band combination of each second terminal capability query instruction, and sends the queried CA combination to the wireless network 2.

In this embodiment, the frequency band combination to be queried of the CA combined frequency band group is a frequency band combination obtained by performing union operation on at least one frequency band combination of the CA combined frequency band group. The CA combined frequency band group corresponds to an aggregation level, and the aggregation level represents the number of the frequency band combinations participating in the calculation of the frequency band combination to be inquired in the CA combined frequency band group. For example, referring to the twelfth table, the frequency band combinations grouped by the fourth CA combined frequency band include three frequency band combinations, which are respectively a frequency band combination composed of the frequency band 1, the frequency band 3, the frequency band 5, and the frequency band 7, a frequency band combination composed of the frequency band 1, the frequency band 3, the frequency band 5, and the frequency band 40, and a frequency band combination composed of the frequency band 1, the frequency band 3, the frequency band 7, and the frequency band 40. For convenience of description, the frequency band combination consisting of the frequency band 1, the frequency band 3, the frequency band 5, and the frequency band 7 in the fourth CA combined frequency band group is labeled as (1, 3, 5, 7), the frequency band combination consisting of the frequency band 1, the frequency band 3, the frequency band 5, and the frequency band 40 is labeled as (1, 3, 5, 40), and the frequency band combination consisting of the frequency band 1, the frequency band 3, the frequency band 7, and the frequency band 40 is labeled as (1, 3, 7, 40). If the aggregation level of the fourth CA combined frequency band group is 1, the frequency band combination to be queried of the fourth CA combined frequency band group is calculated by respectively merging the three frequency band combinations (1, 3, 5, 7), (1, 3, 5, 40), (1, 3, 7, 40) in the fourth CA combined frequency band group with the own frequency band combination, for example, the frequency band combination (1, 3, 5, 7) and the frequency band combination (1, 3, 5, 7) are merged to calculate the frequency band combination to be queried of the fourth CA combined frequency band group as the frequency band combination (1, 3, 5, 7). For example, the frequency band combination (1, 3, 5, 40) and the frequency band combination (1, 3, 5, 40) are subjected to union calculation to obtain the frequency band combination to be queried of the fourth CA combination frequency band group as the frequency band combination (1, 3, 5, 40). For example, the frequency band combination (1, 3, 7, 40) and the frequency band combination (1, 3, 7, 40) are subjected to union calculation to obtain the frequency band combination to be queried of the fourth CA combination frequency band group as the frequency band combination (1, 3, 7, 40).

If the aggregation level of the fourth CA combined frequency band group is 2, the frequency band combination to be queried of the fourth CA combined frequency band group is calculated by a union set of two frequency band combinations (1, 3, 5, 7), (1, 3, 5, 40), and (1, 3, 7, 40) in the fourth CA combined frequency band group. For example, the frequency band combination to be queried of the fourth CA combined frequency band group is obtained by performing union calculation on the first two frequency band combinations (1, 3, 5, 7) and the (1, 3, 5, 40) in the fourth CA combined frequency band group to be the frequency band combination (1, 3, 5, 7, 40), and the last remaining frequency band combination (1, 3, 7, 40) is used as another frequency band combination to be queried of the fourth CA combined frequency band group.

If the aggregation level of the fourth CA combined frequency band group is 3, the frequency band combination to be queried of the fourth CA combined frequency band group is calculated by the union set of the frequency band combinations (1, 3, 5, 7), (1, 3, 5, 40) and (1, 3, 7, 40) in the fourth CA combined frequency band group to obtain (1, 3, 5, 7, 40).

In this embodiment, after determining the frequency band combination to be queried in the fourth CA combined frequency band group, the wireless network 2 generates a second terminal capability query instruction including the frequency band combination to be queried. For example, as described above, after determining that the frequency band combination to be queried of the fourth CA combined frequency band group with aggregation level of 1 is the frequency band combination (1, 3, 5, 7), the frequency band combination (1, 3, 5, 40), and the frequency band combination (1, 3, 7, 40), the wireless network 2 generates the second terminal capability query instruction including the frequency band combination (1, 3, 5, 7), the frequency band combination (1, 3, 5, 40), and the frequency band combination (1, 3, 7, 40). For example, after the wireless network 2 determines that the frequency band combination to be queried of the fourth CA combined frequency band group with the aggregation level of 2 is the frequency band combination (1, 3, 5, 7, 40) and the frequency band combination (1, 3, 7, 40), a second terminal capability query instruction including the frequency band combination (1, 3, 5, 7, 40) and the frequency band combination (1, 3, 7, 40) is generated.

In this embodiment, the aggregation level of the CA combined frequency band groups may be set according to the number of frequency bands of the CA combined frequency band groups. The more the frequency bands grouped by the CA combined frequency band, the lower the aggregation level of the CA combined frequency band grouping is set. For example, the number of bands in the fifth CA combined band packet is 5, and the aggregation level of the fifth CA combined band packet may be set to 1. The number of bands in the fourth CA combined band group is 4, and the aggregation level corresponding to the fourth CA combined band group may be set to 2. The number of bands in the third CA combined band group is 3, and the aggregation level corresponding to the third CA combined band group may be set to 3. The number of bands in the second CA combined band group is 2, and the aggregation level corresponding to the fourth CA combined band group may be set to 4. The number of bands in the first CA combined band group is 1, and the aggregation level corresponding to the fourth CA combined band group may be set to 5. It should be noted that, in other embodiments, the aggregation levels of the fifth CA combined band packet, the fourth CA combined band packet, the third CA combined band packet, the second CA combined band packet, and the first CA combined band packet may also be set to be the same aggregation level.

In this embodiment, the implementation flow of the CA combination method in which the wireless network 2 sends at least one second terminal capability query instruction to the terminal device 1 and receives the combined query of the terminal device 1 according to the frequency bands to be queried of each second terminal capability query instruction may refer to the method steps shown in fig. 5.

In step S508, the wireless network 2 aggregates the CA combinations transmitted by the terminal apparatus 1 to obtain all CA combinations included in the terminal capability information of the terminal apparatus 1.

In this embodiment, the wireless network 2 collects CA combinations transmitted by the terminal apparatus 1 to obtain all CA combinations included in the terminal capability information of the terminal apparatus 1, including: the wireless network 2 deletes the CA combination that is duplicated among the CA combinations transmitted by the terminal apparatus 1 to obtain all CA combinations included in the terminal capability information of the terminal apparatus 1.

Referring to fig. 6, a flowchart of a CA combination obtained by querying a combination of frequency bands to be queried according to each second terminal capability query finger in an embodiment of the present application is shown. The method comprises the following steps.

Step S601, the wireless network 2 sorts the CA combined frequency band groups of the candidate CA combinations, and generates at least one to-be-queried frequency band combination according to the aggregation level of the CA combined frequency band group by the frequency band combination in the CA combined frequency band group with the first rank.

In the present embodiment, the candidate CA combination is described as an example of a CA combination obtained by referring to the CA combination relationship table from band 1, band 3, band 5, band 7, band 19, and band 40. The wireless network 2 ordering the CA combination frequency band groups of the candidate CA combinations includes: and sequencing according to the frequency band number of the CA combined frequency band grouping, wherein the sequencing is closer to the front when the frequency band number of the CA combined frequency band grouping is more. For example, according to the foregoing description, the number of bands in the fourth CA combined band group is 4, the number of bands in the third CA combined band group is 3, the number of bands in the second CA combined band group is 2, the number of bands in the first CA combined band group is 1, and the result of sorting all CA combined band groups is: a fourth CA combined frequency band group, a third CA combined frequency band group, a second CA combined frequency band group and a first CA combined frequency band group.

And sequencing the CA combined frequency band groups of the candidate CA combinations to obtain a fourth CA combined frequency band group (see table twelve), a third CA combined frequency band group (see table eleven), a second CA combined frequency band group (see table ten) and a first CA combined frequency band group (see table nine). The aggregation level of the fourth CA combined frequency band group is 2, the aggregation level of the third CA combined frequency band group is 3, the aggregation level of the second CA combined frequency band group is 4, and the aggregation level of the first CA combined frequency band group is 5. Referring to table twelve, the band combinations of the fourth CA combined band group ordered first include (1, 3, 5, 7), (1, 3, 5, 40), (1, 3, 7, 40). And the frequency band combination to be inquired of the fourth CA combined frequency band group is calculated by combining the frequency band combinations (1, 3, 5, 7) and (1, 3, 5, 40) according to the aggregation level with the value of 2 to obtain the frequency band combination to be inquired of the fourth CA combined frequency band group (1, 3, 5, 7, 40), and the last rest frequency band combinations (1, 3, 7, 40) are used as the other frequency band combination to be inquired of the fourth CA combined frequency band group.

Step S602, selecting a frequency band combination to be queried from at least one frequency band combination to be queried as a target frequency band combination to be queried, generating a second terminal capability query instruction including the target frequency band combination to be queried according to the target frequency band combination to be queried, and sending the second terminal capability query instruction to the terminal device 1.

For example, the wireless network 2 first selects a frequency band combination (1, 3, 5, 7, 40) from the two frequency band combinations to be queried of the fourth CA combined frequency band group as a target frequency band combination to be queried, and generates a second terminal capability query instruction including the frequency band combination (1, 3, 5, 7, 40). The wireless network 2 transmits a second terminal capability query instruction including the frequency band combination (1, 3, 5, 7, 40) to the terminal apparatus 1. The terminal device 1 inquires about a CA combination corresponding to the frequency band 1, a CA combination corresponding to the frequency band 3, a CA combination corresponding to the frequency band 5, a CA combination corresponding to the frequency band 7, a CA combination corresponding to the frequency band 40, and a CA combination corresponding to a frequency band combination composed of two or more of the frequency bands 1, 3, 5, 7, and 40, based on the frequency band combination (1, 3, 5, 7, 40). The terminal device 1 transmits the queried CA combination to the wireless network 2.

Step S603 is to receive a CA combination obtained by combination query of the target frequency band to be queried according to the second terminal capability query instruction and sent by the terminal device 1.

For example, the wireless network 2 receives the CA combination corresponding to the frequency band 1, the CA combination corresponding to the frequency band 3, the CA combination corresponding to the frequency band 5, the CA combination corresponding to the frequency band 7, the CA combination corresponding to the frequency band 40, and the CA combination corresponding to at least two frequency band combinations consisting of the frequency band 1, the frequency band 3, the frequency band 5, the frequency band 7, and the frequency band 40, which are transmitted from the terminal device 1.

Step S604, determining whether the number of the received CA combinations reaches the maximum number of combinations, if the number of the received CA combinations reaches the maximum number of combinations, executing step S605, otherwise, if the number of the received CA combinations does not reach the maximum number of combinations, executing step S606.

Step S605, subtracting the aggregation level value of the currently ordered CA combined frequency band group by one to update the aggregation level of the currently ordered CA combined frequency band group, and generating at least one to-be-queried frequency band combination from the frequency band combination in the currently ordered CA combined frequency band group according to the updated aggregation level. After step S605 is executed, step S602 is executed.

Step S606, determining whether the frequency band combination of the received CA combination includes the frequency band combinations of all candidate CA combinations. If the received frequency band combination of the CA combination does not include the frequency band combinations of all the candidate CA combinations, step S607 is executed, otherwise, if the received frequency band combination of the CA combination includes the frequency band combinations of all the candidate CA combinations, the step is ended.

For example, the wireless network 2 determines that the frequency band combination of the received CA combination does not include the frequency band combination of the candidate CA combination (1, 3, 19).

In step S607, the wireless network 2 deletes the received frequency band combination of the CA combination from the frequency band combinations of the candidate CA combinations to update the frequency band combinations of the candidate CA combinations.

For example, since none of the CA combinations corresponding to the band combinations (1, 3, 19) of the third CA combination band group is in the CA combination of the current query, all band combinations other than the band combinations (1, 3, 19) are deleted from the band combinations of the candidate CA combinations to update the band combinations of the candidate CA combinations.

Step S608, determine whether there is a remaining frequency band combination to be queried in the currently sequenced CA combination frequency band group. If there are remaining combinations of frequency bands to be queried in the currently ordered CA combined frequency band group, step S609 is executed, otherwise, if there are no remaining combinations of frequency bands to be queried in the currently ordered CA combined frequency band group, step S510 is executed.

Step S609 selects a new frequency band combination to be queried from the remaining frequency band combinations to be queried in the currently ordered CA combined frequency band group as a target frequency band combination to be queried, generates a new second terminal capability query instruction according to the target frequency band combination to be queried, and sends the new second terminal capability query instruction to the terminal device 1. Step S603 is executed after step S609 is executed.

For example, the wireless network 2 generates a second terminal capability query instruction including the frequency band combination to be queried (1, 3, 7, 40) by using another frequency band combination to be queried (1, 3, 7, 40) in the fourth CA combined frequency band group as a target frequency band combination to be queried, and sends the second terminal capability query instruction including the frequency band combination to be queried (1, 3, 7, 40) to the terminal device 1. The terminal device 1 inquires about a CA combination corresponding to the frequency band 1, a CA combination corresponding to the frequency band 3, a CA combination corresponding to the frequency band 7, a CA combination corresponding to the frequency band 40, and a CA combination corresponding to at least two frequency band combinations consisting of the frequency band 1, the frequency band 3, the frequency band 7, and the frequency band 40, according to the frequency band combination (1, 3, 7, 40). The terminal device 1 transmits the queried CA combination to the wireless network 2.

Step S610, determine whether there is an inquired CA combined band group. If there is an inquired CA combined band group, step S611 is executed, otherwise, if there is no inquired CA combined band group, the process ends.

Step S611, determining an unexquired frequency band combination in the frequency band combination of the next CA combined frequency band group after the current sequenced CA combined frequency band group, and generating at least one frequency band combination to be inquired according to the aggregation level of the next CA combined frequency band group for the unexquired frequency band combination in the frequency band combination of the next CA combined frequency band group. Step S602 is executed after step S611 is executed.

For example, the wireless network 2 determines that the band combination (1, 3, 19) in the third CA combined band group after the fourth CA combined band group is not queried, and generates the band combination (1, 3, 19) of the third CA combined band group as the band combination (1, 3, 19) to be queried according to the aggregation level with the value of 3. The wireless network 2 generates a second terminal capability query instruction including the frequency band combination (1, 3, 19) according to the frequency band combination (1, 3, 19), and transmits the second terminal capability query instruction including the frequency band combination (1, 3, 19) to the terminal device 1. The terminal device 1 responds to the second terminal capability query instruction including the frequency band combination (1, 3, 19), queries the CA combination corresponding to the frequency band 1, the CA combination corresponding to the frequency band 3, the CA combination corresponding to the frequency band 19, and the CA combination corresponding to the frequency band combination composed of two or more of the frequency bands 1, 3, and 19 according to the frequency band combination (1, 3, 19), and transmits the queried CA combination to the wireless network 2.

In this embodiment, the wireless network 2 ranks the CA combined frequency band groups of the candidate CA combinations, generates at least one frequency band combination to be queried from the frequency band combinations in the CA combined frequency band group ranked first according to the aggregation level of the CA combined frequency band group, selects one frequency band combination to be queried from the at least one frequency band combination to be queried as a target frequency band combination to be queried, generates a second terminal capability query instruction including the target frequency band combination to be queried according to the target frequency band combination to be queried, and sends the second terminal capability query instruction to the terminal device 1.

The terminal device 1 responds to the second terminal capacity query instruction, acquires a target frequency band combination to be queried from the second terminal capacity query instruction, queries a CA combination corresponding to the target frequency band combination to be queried according to the target frequency band combination to be queried, and sends the queried CA combination to the wireless network 2. And when the wireless network 2 determines that the number of the received CA combinations does not reach the maximum combination number, judging whether the inquired frequency band combination of the CA combination comprises the frequency band combinations of all candidate CA combinations. If the frequency band combination of the queried CA combination includes the frequency band combinations of all candidate CA combinations, the queried CA combinations are collected and used as all CA combinations included in the terminal capability information of the terminal apparatus 1.

If the wireless network 2 judges that the frequency band combination of the inquired CA combination does not comprise all the frequency band combinations of the candidate CA combinations, deleting the frequency band combination of the inquired CA combination from the frequency band combinations of the candidate CA combinations to update the frequency band combinations of the candidate CA combinations, and judging whether the frequency band combination to be inquired remains in the first-ranked CA combination frequency band group; if the remaining frequency band combination to be queried exists in the first-ranked CA combined frequency band group, selecting a new frequency band combination to be queried from the remaining frequency band combinations to be queried as a target frequency band combination to be queried, generating a new second terminal capability query instruction according to the target frequency band combination to be queried, sending the new second terminal capability query instruction to the terminal device 1, querying the CA combination according to the new second terminal capability query instruction by the terminal device 1, and sending the queried CA combination to the wireless network 2.

If no remaining frequency band combination exists in the first-order CA combined frequency band group, the wireless network 2 determines the frequency band combination which is not inquired in the frequency band combination of the second-order CA combined frequency band group, generates at least one frequency band combination to be inquired according to the aggregation level of the next CA combined frequency band group, selects a new frequency band combination to be inquired from the at least one frequency band combination to be inquired as a target frequency band combination to be inquired, generates a second terminal capability inquiry command comprising the target frequency band combination to be inquired according to the target frequency band combination to be inquired, sends the second terminal capability inquiry command to the terminal device 1, the terminal device 1 responds to the second terminal capability inquiry command, inquires the CA combination according to the target frequency band combination to be inquired of the second terminal capability inquiry command, and sends the queried CA combination to the wireless network 2. The wireless network 2 marks the frequency band combination of the inquired CA combination in the frequency band combinations of the candidate CA combinations, and judges whether the frequency band combination of the inquired CA combination comprises the frequency band combinations of all the candidate CA combinations; if the frequency band combination of the inquired CA combination includes the frequency band combinations of all candidate CA combinations, summarizing all the inquired CA combinations to be used as all CA combinations included in the terminal capability information of the terminal device 1; if the frequency band combination of the inquired CA combination does not include the frequency band combinations of all candidate CA combinations, the wireless network 2 continuously selects a new frequency band combination to be inquired from the remaining frequency band combinations to be inquired in the second-order CA combination frequency band group as the target frequency band combination to be inquired, generates a second terminal capacity inquiry instruction including the target frequency band combination to be inquired, transmits the generated second terminal capacity inquiry instruction to the terminal device 1, receives the CA combination inquired according to the second terminal capacity inquiry instruction and sent by the terminal device 1 until the frequency band combination of the inquired CA combination includes the frequency band combinations of all candidate CA combinations or no remaining frequency band combination to be inquired in the frequency band combinations of all CA combinations is not inquired.

In the application, a terminal device 1 responds to a first terminal capacity query instruction sent by a wireless network 2, queries to obtain terminal capacity information including candidate CA combinations, and sends the terminal capacity information to the wireless network 2, when the wireless network 2 determines that the candidate CA combinations sent by the terminal device 1 do not reach the maximum combination number, the candidate CA combinations are used as all CA combinations included in the capacity information of the terminal device 1, however, when the candidate CA combinations sent by the terminal device 1 reach the maximum combination number, the wireless network 2 groups the candidate CA combinations according to the frequency band number to obtain CA combination frequency band groups, respectively generates a second terminal capacity query instruction according to the frequency band to be queried of each CA combination frequency band group and then sends the second terminal capacity query instruction to the terminal device 1, the terminal device 1 queries the CA combination corresponding to the frequency band group to be queried according to the frequency band combination of the second terminal capacity query instruction, and transmits the queried CA combination to the wireless network 2. The wireless network 2 collects the CA combinations sent by the terminal device 1 to obtain all CA combinations included in the capability information of the terminal device 1, and the technical problem that all CA combinations of the terminal capability information cannot be reported to the wireless network 2 when the CA combinations reported by the terminal device 1 exceed the maximum combination number is solved.
