This scenario where a terminal device is connected to two base stations with different access technologies at the same time can be referred to as multi-RAT dual connectivity (MR-DC).

For terminal devices, some terminal devices may support MR-DC scenarios, and some terminal devices do not support MR-DC scenarios. Therefore, the terminal devices can send the capability information of the terminal devices to the base station in advance, so that the base station can determine that the terminal devices can work. In which scenarios.

At present, for terminal devices supporting MR-DC capabilities, when sending the terminal device's capability information to the base station, the capability information is divided into three parts and these three parts are the terminal device's capability information under LTE. , Capability information of terminal equipment under NR, and capability information of terminal equipment under MR-DC. The capability information of the terminal device under MR-DC may include a combination relationship between the capability information of the terminal device under NR and the capability information of LTE. For example, the terminal device supports NR band combination 1 under NR. LTE band combination 1 is supported under LTE, and a combination relationship supported by the terminal device under MR-DC is NR band combination 1 and LTE band combination 1. The capability information of the terminal device under MR-DC may include NR band combination 1 Capability information and capability information of the corresponding LTE band combination 1. When the terminal device sends the capability information under NR, it sends the capability information of NR band combination 1.

Among them, when a terminal device is connected to both an LTE base station and an NR base station, if the LTE base station serves as the primary base station and the NR base station serves as the secondary base station, this scenario is specifically referred to as LTE-NR dual connectivity (LTE-NR dual connectivity, EN -DC); and if the NR base station serves as the primary base station and the LTE base station serves as the secondary base station, this scenario is specifically referred to as NR-LTE dual connectivity (NE-DC) in MR-DC. In this article, the NE-DC is used as an example for introduction, that is, the terminal device can send the capability information of the terminal device under the NE-DC to the network device.

5) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "Multiple" means two or more. In view of this, in the embodiments of the present application, "multiple" can also be understood as "at least two", such as two, three or more. "At least one", such as one, two, three or more, for example, "at least one frequency band combination", may include one frequency band combination, two frequency band combinations, three frequency band combinations, or more frequency band combinations. "And / or" describes the association relationship of the associated objects, and indicates that there can be three kinds of relationships. For example, A and / or B can mean that there are three cases in which A exists alone, A and B exist, and B exists alone.

And, unless otherwise stated, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority, or Importance. For example, the first capability information and the second capability information are only used to distinguish different capability information, and do not indicate differences in priority or importance of the two types of capability information.

As described above, some concepts related to the embodiments of the present application are introduced, and the technical features of the embodiments of the present application are introduced below, which are described in detail below with reference to FIG. 1.

FIG. 1 is a process in which a terminal device reports capability information to a network device. This process can take place in the radio resource control connection establishment process (radio resource control connection setup procedure) of the terminal device. In addition, this process is applied to the 4G system as an example, so the core network device is based on the MME as an example.

S11. The access network device sends an initial UE message to the MME, and the MME receives the initial UE message from the access network device.

After the RRC connection between the terminal device and the access network device is established, the access network device sends an initial UE message to the MME.

S12. The MME sends a UE context establishment request (UE context setup request) to the access network device, and the access network device receives the UE context establishment request from the MME.

After receiving the initial UE message, the MME checks whether the capability information of the terminal device (that is, the UE) is stored locally. If the capability information of the terminal device is stored locally, the MME includes the capability information of the terminal device in the UE. The context establishment request is sent to the access network device, and if the capability information of the terminal device is not stored locally, the MME does not include the capability information of the terminal device in the UE context establishment request.

Then, if the UE context establishment request received by the access network device includes capability information of the terminal device, execute S13, and if the UE context establishment request received by the access network device does not include capability information of the terminal device, execute S14.

S13. The access network device stores capability information of the terminal device.

The access network device may use the capability information of the terminal device to communicate with the terminal device. At this point, the process can be considered to be over.

S14. The access network device sends a UE capability request message to the terminal device, and the terminal device receives the UE capability request message from the access network device.

Because the UE context establishment request received by the access network device does not include the capability information of the terminal device, the access network device may request the terminal device to obtain the capability information of the terminal device.

S15. The terminal device sends a UE capability information (UE capability information) message to the access network device, and the access network device receives the UE capability information message from the terminal device.

The UE capability information message includes capability information of the terminal device. At present, when the terminal device sends the capability information of the terminal device to the network device, the capability information is divided into three parts and the three parts are the capability information of the terminal device under LTE and the capability information of the terminal device under NR. And the capability information of the terminal equipment under MR-DC. Among them, the capability under LTE includes at least the frequency band combination supported by the terminal device under LTE, the capability under NR includes at least the frequency band combination supported by the terminal device under NR, and the capability under MR-DC includes at least when the terminal device operates simultaneously with LTE and NR Supported frequency band combinations. Please refer to FIG. 2, which is a schematic diagram of a terminal device sending terminal device capability information under LTE to a network device. For example, a terminal device supports band combination 1 and band combination 2 under LTE. Band combination 1 includes bands 1 to x. In the example in FIG. 2, x may be greater than 3, a carrier is included in band 1, and band 2 is included. It includes 2 carriers, 3 carriers in band 3, and X carriers in band x. For example, the band combination capability information of the terminal device under LTE may include the bandwidth, subcarrier interval, and modulation corresponding to these carriers. At least one of a method, channel state information (channel state information, CSI) process capability, or multiple-input multiple-output (MIMO) capability. Similarly, the band combination 2 includes the frequency bands 1 to y. In the example in FIG. 2, y may be greater than 2, including one carrier in frequency band 1, five carriers in frequency band 2, and frequency band y. For example, if Y carriers are included below, the frequency band combination capability information of the terminal device under LTE will also include at least one of the bandwidth, subcarrier interval, modulation mode, CSI capability, or MIMO capability corresponding to these carriers.

When the terminal device sends the frequency band combination capability information of the terminal device under the NR and the frequency band combination capability information under the NE-DC to the network device, the methods are similar, and if the capability information is under the NE-DC, Then, the corresponding LTE band combination capability information and NR's band combination capability information are included in the same manner as shown in FIG. 2.

For example, please refer to FIG. 3, which is a schematic diagram of sending terminal device capability information into three parts for the terminal device. The three parts are the terminal device's capability information under LTE, the terminal device's capability information under NR, and the terminal. Device capability information under MR-DC. For example, the terminal device sends the three pieces of capability information in a message, for example, the UE capability information message in S15, and the UE capability information message is, for example, a radio resource control (RRC) message. These three parts are located in three containers in the UE capability information message. One container can be understood as a field, where the capability information of the terminal device under LTE is located in the LTE container, and the capability information of the terminal device under NR. It is located in the NR container, and the capability information of the terminal device under the NE-DC is located in the MR-DC container. It can be seen in Figure 3 that the LTE container includes the LTE band combination list of the terminal equipment, that is, the list of frequency band combinations supported by the terminal device under LTE. The NR container includes the NR band combination list of the terminal device ( NR (bandcombination list), which is the list of frequency band combinations supported by terminal equipment under NR. The MR-DC container includes the correspondence between the frequency band combinations supported by terminal equipment under LTE and the frequency band combinations supported by terminal equipment under NR. Alternatively, this correspondence relationship may be referred to as a MR-DC band combination. For example, the MR-DC frequency band combination supported by the terminal device includes MR-DC frequency band combination 1 to MR-DC frequency band combination x, the frequency band combination supported by the terminal device under LTE includes LTE frequency band combination 1 to LTE frequency band combination x, and the terminal device is in NR The supported band combinations include NR band combination 1 to NR band combination y, where MR-DC band combination 1 includes LTE band combination 1 and NR band combination 1, and MR-DC band combination 2 includes LTE band combination 2 and NR band combination. 2. Wait. Therefore, the MR-DC container also includes the capability information of the LTE frequency band combination 1, the capability of the NR frequency band combination 1, the capability of the LTE frequency band combination 2, and the capability of the NR frequency band combination 2. Among them, the LTE container and the MR-DC container The content can be parsed by the LTE base station, and the content in the NR container and the MR-DC container can be parsed by the NR base station. It can be seen that no matter for the LTE base station or the NR base station, the terminal device repeatedly sends the capability information of part of the frequency band combination.

S16. The access network device stores capability information of the terminal device.

The access network device may use the capability information of the terminal device to communicate with the terminal device. For example, after receiving the UE capability information message, the network device can configure the PDCP configuration, physical layer configuration, radio frequency configuration, and measurement configuration of the terminal device according to the capability information of the terminal device to ensure that the configuration of the terminal device can meet the capabilities of the terminal device itself. That is, the terminal device can work normally under the configuration of the network device.

S17. The access network device sends a UE capability information indication to the MME, and the MME receives the UE capability information indication from the access network device.

Because the MME does not store the capability information of the terminal device, the access network device may send a UE capability information indication to the MME, and the UE capability information indication may include the capability information of the terminal device.

S18. The MME stores capability information of the terminal device.

According to the process shown in FIG. 1, when the terminal device sends the capability information of the terminal device to the network device, it may be repeatedly sent, which results in a large amount of information sent by the terminal device and increases system overhead.

In view of this, in the embodiment of the present application, if the terminal device determines that the first capability information includes the capability information of the first frequency band combination of the terminal device under the first radio access technology, then the second capability information determined by the terminal device It does not include the capability information of the first frequency band combination of the terminal device under the first radio access technology, which is equivalent to transmitting the same capability information only once to minimize the situation of repeated transmission, thereby saving system overhead.

The technical solutions provided in the embodiments of the present application may be applied to a 5G system, or an LTE system, or may be applied to a next-generation mobile communication system or other similar communication systems, which are not specifically limited.

The network device in FIG. 4 is, for example, an access network device, such as a base station. Among them, the access network device corresponds to different devices in different communication systems, for example, it can correspond to an eNB in a 4G system, and an access network device in a 5G system, such as gNB in a 5G system.

In the following description, the method is applied to the network architecture shown in FIG. 4 as an example. In addition, the method may be executed by two communication devices, such as a first communication device and a second communication device, where the first communication device may be a network device or capable of supporting the functions required by the network device to implement the method The communication device, or the first communication device may be a terminal device or a communication device capable of supporting the functions required by the terminal device to implement the method, and of course, it may also be another communication device, such as a chip system. The same is true for the second communication device. The second communication device may be a network device or a communication device capable of supporting functions required by the network device to implement the method, or the second communication device may be a terminal device or capable of supporting the terminal device to implement the method. The communication device with the required functions can of course also be other communication devices, such as a chip system. And there are no restrictions on the implementation of the first communication device and the second communication device. For example, the first communication device may be a network device, the second communication device is a terminal device, or the first communication device and the second communication device are both networks. The device, or the first communication device and the second communication device are both terminal devices, or the first communication device is a network device, the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

For ease of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, a first communication device is a terminal device and a second communication device is a network device. Because this article uses the method in the network architecture shown in FIG. 4 as an example, the network equipment described below can be the network equipment in the network architecture shown in FIG. 4 and the terminal equipment described below It may be a terminal device in the network architecture shown in FIG. 4.

S51. The terminal device determines that the first capability information of the terminal device includes capability information of a first frequency band combination of the terminal device under a first radio access technology, where the first capability information is The combination of the capability information of the frequency band combination under the first radio access technology and the capability information of the frequency band combination of the terminal device under the second radio access technology;

S52. The terminal device determines second capability information of the terminal device, where the second capability information is capability information of a frequency band combination of the terminal device under the first radio access technology, and the second capability The information does not include capability information of the first frequency band combination of the terminal device under the first radio access technology included in the first capability information;

S53. The terminal device sends the first capability information and the second capability information of the terminal device to a network device, and the network device receives the first capability of the terminal device from the terminal device. Information and the second capability information;

S54. The network device obtains capability information of a frequency band combination of the terminal device under the first radio access technology according to the first capability information and the second capability information.

The first capability information is a combination of the capability information of the frequency band combination of the terminal device in the first radio access technology and the capability information of the frequency band combination of the terminal device in the second radio access technology. The combination is used to express the capability of the frequency band combination supported by the terminal device when the first wireless technology and the second wireless technology work simultaneously. For example, if the terminal device supports band combination 1 under the first radio access technology and band combination 2 under the second radio access technology, a combination of capability information included in the first capability information may be band combination 1 and band combination. 2. Wherein, the frequency band combination includes a frequency band combination with the first radio access technology as the main base station and / or a frequency band combination with the second radio access technology as the main base station, that is, the first radio access technology is The frequency band combination of the main base station or the frequency band combination of the second radio access technology as the main base station, or the frequency band combination of the first radio access technology as the main base station and the frequency band combination of the second radio access technology as the main base station.

The first capability information includes, for example, EN-DC capability information of the terminal device, or the NE-DC capability information of the terminal device, and the second capability information includes, for example, NR capability information of the terminal device. The first wireless access technology is The NR or the second capability information includes LTE capability information of the terminal device, and the first radio access technology is LTE. For the convenience of introduction, in this embodiment, the first capability information includes NE-DC capability information of the terminal device, the second capability information includes NR capability information of the terminal device, and the first radio access technology is NR. example. Among them, the NR capability information of the terminal device refers to the capability information of the frequency band combination of the terminal device under NR, the LTE capability information of the terminal device refers to the capability information of the frequency band combination of the terminal device under LTE, and the NE-DC of the terminal device The capability information refers to the capability information of the frequency band combination of the terminal device under the NE-DC, and the EN-DC capability information of the terminal device refers to the capability information of the frequency band combination of the terminal device under the EN-DC.

The terminal device can determine the first capability information of the terminal device, that is, determine the NE-DC capability information of the terminal device. For example, the NE-DC capability information of the terminal device can be understood to include at least one combination of capability information, and one capability information combination represents an LTE The combination relationship between the capability information of the frequency band combination and the capability information of an NR frequency band combination, or that the capability information combination includes an LTE frequency band combination and an NR frequency band combination, then the NE-DC capability information of the terminal device may include at least one such That is, the NE-DC capability information of the terminal device may include one capability information combination, two capability information combinations, or more capability information combinations. Among them, a combination of capability information represents a complete NE-DC capability. A terminal device can support one of the NE-DC capabilities at a time, and can support different NEs included in the NE-DC capability information at different times. -DC capability, that is, the capability corresponding to different combinations of capability information included in the NE-DC capability information can be achieved at different times.

Since the NE-DC capability information of the terminal device will include the capability information of the LTE frequency band combination and the capability information of the NR frequency band combination, and the information of these NR frequency band combinations is also part of the capability information or all the capability information in the NR capability information of the terminal device, Therefore, when the terminal device determines the NR capability information of the terminal device, it is no longer necessary to include the NR capability information included in the NE-DC capability information, that is, the second capability information determined by the terminal device may not include The capability information of the frequency band combination of the terminal device under the NR that is already included in the first capability information, or in short, the second capability information determined by the terminal device may not include the capability information already included in the first capability information. That is, the second capability information does not include the capability information in the first capability information, which means that the second capability information does not include the capability of the frequency band combination of the terminal device under the first radio access technology included in the first capability information. information. For example, the first capability information includes capability information of the first frequency band combination of the terminal device under the NR, then the second capability information does not include capability information of the first frequency band combination of the terminal device under the NR. The first frequency band combination may include one or more frequency band combinations.

Alternatively, S51, S52, and S53 can also be described as: the terminal device determines the capability information of the first frequency band combination and the capability information of the second frequency band combination of the terminal device under the first radio access technology, and the terminal device sends the terminal to the network device The first capability information and the second capability information of the device. The first capability information is the capability information of the frequency band combination of the terminal device under the first radio access technology and the capability information of the frequency band combination of the terminal device under the second radio access technology. The second capability information is the capability information of the frequency band combination of the terminal device in the first radio access technology, and the first capability information includes the capability information of the first frequency band combination of the terminal device in the first radio access technology, The second capability information includes capability information of a second frequency band combination supported by the terminal device under the first radio access technology. The first frequency band combination may include one or more frequency band combinations, and the second frequency band combination may include one or more frequency band combinations. That is, the capability information of the frequency band combination of the terminal device under the first radio access technology includes the capability information of the first frequency band combination and the capability information of the second frequency band combination, and the capability information of the first frequency band combination is also included in the first In the capability information, the second capability information no longer includes capability information of the first frequency band combination, but only includes capability information of the second frequency band combination. Take the first capability information as NE-DC capability information, the second capability information as NR capability information, and the first radio access technology as NR as an example. For example, the capability information of a terminal device to determine the combination of frequency bands of the terminal device under the NR includes the NR frequency band. The capability information of combination 1 and the capability information of NR band combination 2, and the capability information of NR band combination 1 is included in the NE-DC capability information of the terminal device, so the NR capability information of the terminal device no longer includes the NR band combination The capability information of 1 is included, and only the capability information of NR band combination 2 is included.

For example, please refer to Table 1 for an example of NE-DC capability information of a terminal device:

Table 1

LTE频带组合1LTE Band Combination 1	NR频带组合1NR band combination 1
LTE频带组合2LTE Band Combination 2	NR频带组合2NR Band Combination 2
LTE频带组合3LTE Band Combination 3	NR频带组合3NR Band Combination 3

A row in Table 1 indicates a capability information combination. For example, LTE band combination 1 and NR band combination 1 belong to a capability information combination.

The terminal device may also determine the second capability information of the terminal device, that is, determine the NR capability information of the terminal device. For example, the terminal equipment determines that the NR capability information of the terminal equipment includes capability information of NR band combination 1, capability information of NR band combination 2, capability information of NR band combination 3, and capability information of NR band combination 4. According to Table 1, it can be known that the terminal The NE-DC capability information of the device already includes the capability information of the NR band combination 1, the capability information of the NR band combination 2, and the capability information of the NR band combination 3. Therefore, the NR capability information of the terminal device determined by the terminal device includes The capability information of the NR band combination 1, the capability information of the NR band combination 2 and the capability information of the NR band combination 3 may no longer be included, and then the NR capability information determined by the terminal device may include only the capability information of the NR band combination 4. In this way, the probability that the terminal device repeatedly reports the capability information can be reduced, and transmission resources can be saved.

Of course, the same is true for the LTE capability information of the terminal device. For example, the terminal device may also determine the third capability information of the terminal device. The third capability information is the capability information of the frequency band combination of the terminal device under the second radio access technology. The third capability information includes, for example, the NR capability of the terminal device. Information, the second radio access technology is NR, or the third capability information includes LTE capability information of the terminal device, and the second radio access technology is LTE. In this embodiment, the first radio access technology is NR, and the second radio access technology is LTE. Then, the terminal device may also determine the third capability information of the terminal device, that is, determine the LTE capability information of the terminal device. Since the NE-DC capability information of the terminal device includes information of the LTE frequency band combination and the NR frequency band combination, and the information of these LTE frequency band combinations is also part or all of the capability information in the LTE capability information of the terminal device, therefore, When the terminal device determines the LTE capability information of the terminal device, it is no longer necessary to include the LTE capability information included in the NE-DC capability information, that is, the third capability information determined by the terminal device may not include the first The capability information of the frequency band combination of the terminal device under LTE that is already included in the capability information, or in short, the third capability information determined by the terminal device may not include the capability information already included in the first capability information, that is, The third capability information does not include the capability information in the first capability information, which means that the third capability information does not include the capability information of the frequency band combination of the terminal device under the second radio access technology included in the first capability information. For example, the first capability information includes the capability information of the second frequency band combination of the terminal device under LTE, so the third capability information does not include the capability information of the second frequency band combination of the terminal device under LTE, the second frequency band here The combination is not the same concept as the second frequency band combination mentioned in the previous description of S51, S52, and S53 in another way. Or, if the situation of S51, S52, and S53 is described in another way, it can be understood that the first capability information includes the capability information of the third frequency band combination of the terminal device under LTE, so the third capability information does not include Includes capability information of the third frequency band combination supported by the terminal device under LTE. The third frequency band combination may include one or more frequency band combinations.

For example, the terminal device determines that the LTE capability information of the terminal device includes capability information of LTE band combination 1, capability information of LTE band combination 2, capability information of LTE band combination 3, capability information of LTE band combination 4, and capability of LTE band combination 5. For information, you can see that the NE-DC capability information of the terminal equipment in Table 1 already includes the capability information of the LTE band combination 1, the capability information of the LTE band combination 2, and the capability information of the LTE band combination 3. The determined LTE capability information of the terminal device may no longer include the capability information of the LTE band combination 1, the capability information of the LTE band combination 2 and the capability information of the LTE band combination 3. Then, the LTE capability information determined by the terminal device may be Only the capability information of the LTE band combination 4 and the capability information of the LTE band combination 5 are included. In this way, the probability that the terminal device repeatedly reports the capability information can be reduced, and transmission resources can be saved.

The terminal device determines the first capability information, the second capability information, and the third capability information of the terminal device, and the order of the three processes is not limited in the embodiment of the present application. For example, the terminal device may first determine the first capability information and then determine the second capability information and the third capability information. When determining the second capability information and the third capability information, it may be determined at the same time, or it may be determined in a time-sharing manner, without limiting which The capability information is determined first, or the terminal device may determine the first capability information, the second capability information, and the third capability information at the same time, and so on.

After determining the first capability information and the second capability information, the terminal device can send the first capability information and the second capability information to the network device, so that the network device can obtain the terminal device's presence in the first according to the first capability information and the second capability information. Capability information for band combinations under a radio access technology. For example, the network device can obtain the capability information of the first frequency band combination of the terminal device included in the first capability information under the first radio access technology, and obtain the capability information of the frequency band combination included in the second capability information. Capability information of the frequency band combination of the terminal device under the first radio access technology. Continue to take as an example the first capability information including NE-DC capability information of the terminal device, the second capability information including NR capability information of the terminal device, and the first radio access technology being NR. For example, the network device acquires the capability information of the first frequency band combination of the terminal device under the NR included in the first capability information. For example, the capability information of the first frequency band combination includes the capability information of the NR frequency band combination 1, and the capability information of the NR frequency band combination 2. And the NR band combination 3 capability information, and the network device obtains the capability information of the band combination included in the second capability information, for example, the NR band combination 4 capability information, then the network device can obtain the frequency band of the terminal device under the NR The combined capability information is capability information of NR band combination 1, capability information of NR band combination 2, capability information of NR band combination 3, and capability information of NR band combination 4.

The terminal device sends the first capability information and the second capability information to the network device, which may be sent through a message, for example, the UE capability information message in S15 in the process shown in FIG. 1, or may be sent through different two Messages are sent, and if the first capability information and the second capability information are sent through two messages, the terminal device may send the first capability information first and then the second capability information, or the second capability information first and then the first capability information. Capability information, or the first capability information and the second capability information are sent simultaneously.

Of course, if the terminal device also determines the third capability information, it can also send the third capability information to the network device. After receiving the third capability information from the terminal device, the network device can also obtain the terminal device in the second wireless connection. Capability information of the frequency band combination under the input technology. Taking the second radio access technology as LTE as an example, the manner in which the network device obtains the capability information of the frequency band combination of the terminal device under LTE is similar to the manner of obtaining the capability information of the frequency band combination of the terminal device under NR. For example, The network device may obtain the capability information of the second frequency band combination (or the third frequency band combination in another description manner) of the terminal device included in the first capability information under the second radio access technology, and the third capability information. The capability information of the frequency band combination included in the terminal information is used to obtain the capability information of the frequency band combination of the terminal device under the second radio access technology.

For example, please refer to FIG. 6, which is an example of a terminal device sending first capability information, second capability information, and third capability information to a network device. For example, the terminal device sends the first capability information, the second capability information, and the third capability information to the network device. Put in a message, but send it in three parts, for example, the message is the UE capability information message in S15. The first capability information, the second capability information, and the third capability information are respectively located in three containers in the UE capability information message. The third capability information is located in the LTE container, and the second capability information is located in the NR container. The first capability is The information is located in the MR-DC container. As can be seen in Figure 6, the LTE container includes the LTE band combination list of the terminal device, which is the list of band combinations supported by the terminal device under LTE. The NR container includes the NR band combination list of the terminal device, that is, the terminal device is in List of frequency band combinations supported under NR. The MR-DC container includes the correspondence between the frequency band combinations supported by terminal equipment under LTE and the frequency band combinations supported by terminal equipment under NR, or this correspondence relationship can also be referred to as MR-DC band combination, here NE-DC is taken as an example, so this correspondence relationship can also be called NE-DC band combination. For example, the NE-DC frequency band combination supported by the terminal device includes NE-DC frequency band combination 1 to NE-DC frequency band combination x, the frequency band combination supported by the terminal device under LTE includes LTE frequency band combination 1 to LTE frequency band combination x, and the terminal device is in NR The supported band combinations include NR band combination 1 to NR band combination y. Among them, NE-DC band combination 1 includes LTE band combination 1 and NR band combination 1, and NE-DC band combination 2 includes LTE band combination 2 and NR band combination. 2. Wait. Therefore, the NE-DC container includes capability information of LTE band combination 1, capability information of NR band combination 1, capability information of LTE band combination 2, and capability information of NR band combination 2. Then, LTE does not include LTE in the LTE container. The capability information of band combination 1 and the capability information of LTE band combination 2 only include the capability information of LTE band combination 3 to the capability information of LTE band combination x. Similarly, the capability information of NR band combination 1 is not included in the NR container. The capability information of the NR band combination 2 includes the capability information of the NR band combination 3 to the capability information of the NR band combination y. Through the technical solution provided in the embodiment of the present application, the probability that a terminal device repeatedly sends the same capability information is reduced, which helps to save system resources.

Wherein, the terminal device sends the first capability information, the second capability information, and the third capability information to the network device, which may be sent through a message, for example, the UE capability information message in S15 in the process shown in FIG. 1, or also It can be sent through different messages, for example, three messages can be sent separately, or two kinds of capability information can be sent through one message, and the remaining kind of capability information is sent through another message. Moreover, if these three kinds of capability information are sent through two messages, Send three or three messages, there is no restriction on the order in which these messages are sent.

The terminal device needs to use the method provided in the embodiment of the present application to send the capability information of the terminal device to the network device. As an optional implementation manner, the terminal device may send instruction information to the network device, which is used to instruct the terminal device to send The second capability information does not include the capability information in the first capability information, and / or the third capability information instructed by the terminal device does not include the capability information in the first capability information.

Which way the access network device chooses to send can be determined by the access network device itself, or negotiated in advance between network devices, or it can also be determined based on the capabilities of other network devices. For example, the access network device may know the capabilities of other network devices in advance.

The capability information is sent to other network devices. For example, the network device may add the capability information of the second frequency band combination of the terminal device included in the first capability information in the second radio access technology to the third capability information to obtain the updated third capability information, and the network device may Send the updated third capability information to other network devices. Alternatively, the network device may also directly send the first capability information and the third capability information to other network devices, and the other network devices may obtain the capability information of the frequency band combination of the terminal device under the second radio access technology by itself.
