Description

Capability information receiving and sending method and device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for receiving and sending capability information.
Background
Currently, the technology is directed to fifth generation mobile communication technology (the) 5thgeneration, 5G) New Radio (NR) defines two major networking modes, stand-alone (SA) and non-stand-alone (NSA). The independent networking mode of the 5G NR requires deployment of an end-to-end all-new network of the 5G system, including a new access network (e.g., nrgbb) and a new generation core (next generation core), and the 5G system independently carries a complete control-plane (CP) and a user-plane (UP), so that the 5G system can operate without depending on a Long Term Evolution (LTE) system and independently provides communication services for users. In the non-independent networking mode, the 5G system needs to rely on the existing LTE system, that is, the NR system and the LTE system need to cooperate with each other to work, for example, a multi-RAT dual connectivity (MR-DC) mode is adopted, and the NR base station and the LTE base station are simultaneously connected with a user to provide a communication service for the user together. In the LTE system, the access network part may be referred to as evolved universal mobile telecommunications system terrestrial radio access (E-UTRA), i.e. a mobile communication radio network in LTE, and the E-UTRA may be regarded as an air interface technology of LTE to some extent. The E-UTRA comprises the E-UTRA, terminal equipment and an evolved node B (eNodeB).
Specifically, the independent networking mode may include a networking mode: the terminal equipment accesses the E-UTRA base station and the E-UTRA base station connects with the fourth generation mobile communication technology (the 4)thgeneration, 4G) core network (abbreviation: LTE independent networking), the terminal device accesses the enhanced E-UTRA base station and the enhanced E-UTRA base station is connected to a 5G core network (short for: an lte independent networking mode), the terminal device accesses to the NR base station, and the NR base station is connected to a 5G core network (abbreviated: NR independent networking approach); networking modes which are not independent networking modes (the terminal equipment is simultaneously accessed to the E-UTRA base station and the NR base station) may comprise: the E-UTRA base station is a main base station, the NR base station is a secondary base station, the E-UTRA base station is connected with a 4G core network (E-UTRA-NR double connection (EN-DC) networking mode for short), the E-UTRA base station is a main base station, the NR base station is a secondary base station, and the E-UTRA base station is connected with a 5G core network (NG E-UTRA-NR double connection (NG-EN-DC) networking mode for short)) The NR base station is a primary base station, the E-UTRA base station is a secondary base station, and the NR base station is connected to a 5G core network (abbreviated: NR-E-UTRA dual connectivity (NE-DC) networking).
At present, a terminal device may support one or more networking modes of the above six networking modes, and the terminal device needs to report related capability information to a base station according to the supported networking modes, so that the base station can reasonably schedule the terminal device. At present, a terminal device reports capability information in a manner of reporting capability information, and the capability information reported by the terminal device includes three parts: an E-UTRA-capable part (carried in an E-UTRA container (container)), an NR-capable part (carried in NRcontainer), and an MR-DC-capable part (carried in MRDC container). However, the terminal device only reports the capability information of each part, and the base station cannot clearly determine the networking mode specifically supported by the terminal device, which may cause the base station to erroneously configure the terminal device.
Disclosure of Invention
The embodiment of the application provides a capability information receiving and sending method and device, which are used for enabling network equipment to determine the real capability of terminal equipment.
In a first aspect, a first capability information receiving method is provided, where the method includes: the method comprises the steps that network equipment receives a capability message from terminal equipment, wherein the capability message is used for indicating capability information of the terminal equipment; if the capability message comprises first information, the network device determines that the terminal device supports the first networking mode, and the first information is used for indicating the first networking mode supported by the terminal device.
The method may be performed by a first communication device, which may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, but may also be other communication devices, such as a system-on-chip. Here, the first communication apparatus is taken as an example of a network device.
In this embodiment of the application, the terminal device may indicate, through the capability message, whether the terminal device supports the first networking mode, for example, the capability message includes the first information, which indicates that the terminal device supports the first networking mode, so that the network device can make explicit the networking mode actually supported by the terminal device through the indication, so as to reasonably configure or schedule the terminal device.
With reference to the first aspect, in a first possible implementation manner of the first aspect, the capability message includes a first capability unit, where the first capability unit is used to indicate capability information of a first radio access technology of the terminal device, and the first capability unit includes the first information.
If the first radio access technology is E-UTRA, for example, the first capability unit may be LTE container or UE-EUTRA-capability field, and the terminal device sends the capability information of E-UTRA to the network device in the LTE container or in the UE-EUTRA-capability field of the capability message. The first information may be included in the first capability unit and may indicate a first networking mode that the terminal device may support if the first radio access technology is supported, so that the indication of the first information is more explicit.
With reference to one possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the first information indicates a core network capability of the first networking mode supported by the terminal device.
In this embodiment of the application, the first information may indicate a core network capability of the first networking mode supported by the terminal device, and by combining the capability information of the radio access technology supported by the terminal device and the core network capability supported by the terminal device, the core network capability of the first networking mode supported by the terminal device, that is, the first networking mode supported by the terminal device, may be known. Or, the first information may also directly indicate the first networking mode supported by the terminal device, and this indication mode is simpler and more direct. Or, the first information indicates to which first networking modes the terminal device supports handover, and the first networking modes that the terminal device supports handover are the first networking modes supported by the terminal device. How the first information is indicated at all may be specified by a protocol or pre-configured by the network device.
With reference to the first aspect, in a third possible implementation manner of the first aspect, the method further includes: if the capability message does not include the first information, the network device determines that the terminal device does not support the first networking mode.
The terminal device may indicate whether the terminal device supports the first networking mode by whether the capability message includes the first information, for example, the capability message includes the first information to indicate that the terminal device supports the first networking mode, or if the capability message does not include the first information, to indicate that the terminal device does not support the first networking mode. In this way, the indication is relatively simple and the overhead of the capability message can be saved to a certain extent. When the indication is performed in this manner, the content of the first information may not be limited, for example, the first information may be information additionally added in the capability message, may be special indication information, or the first information may also be information already existing in the capability message, which is not limited specifically.
With reference to the first aspect, in a fourth possible implementation manner of the first aspect, the method further includes: if the capability message includes second information, the network device determines that the terminal device does not support the first networking mode, and the second information is used for indicating that the terminal device does not support the first networking mode.
In this case, the first information and the second information may be regarded as indication information, and it may be understood that the terminal device carries the indication information in the capability message, and indicates whether the terminal device supports the first networking mode or not by an explicit indication mode. For example, whether the indication information is the first information or the second information may be distinguished by different values of the indication information, if the value of the indication information is the first value, the indication information is specifically the first information, which indicates that the terminal device supports the first networking mode, and if the value of the indication information is the second value, the indication information is specifically the second information, which indicates that the terminal device does not support the first networking mode; alternatively, whether the indication information is the first information or the second information may be distinguished by different information, for example, if the content of the indication information is the first content, the indication information is the first information, and if the content of the indication information is the second content, the indication information is the second information. The specific implementation of the indication information is not limited.
With reference to the first aspect or any one of the first to fourth possible implementations of the first aspect, in a fifth possible implementation of the first aspect, the method further includes: if the capability message includes third information, the network device determines that the terminal device supports a second networking mode, and the third information is used for indicating that the terminal device supports the second networking mode.
If the terminal device supports the first networking mode and supports the second networking mode, the capability message may further include third information, where the third information is used to indicate that the terminal device supports the second networking mode. After the network device receives the capability information, if the capability information includes the third information, the network device may determine that the terminal device supports the second networking mode. Taking the first networking mode as an eLTE independent networking mode as an example, the second networking mode can be an NGEN-DC networking mode. For example, the third information may also be located in a first capability unit, such as an LTE container or a UE-EUTRA-capability field. That is, the LTE container or UE-EUTRA-capability field may include first information and third information, where the first information may indicate that the terminal device supports an LTE independent networking mode, and the third information may indicate that the terminal device supports an NGEN-DC networking mode. Therefore, according to the LTE container or the UE-EUTRA-capability field, the network device can determine whether the terminal device supports the first networking mode or not, and also can determine whether the terminal device supports the second networking mode or not so as to better configure or schedule the terminal device.
In a second aspect, a second capability information sending method is provided, where the method includes: the terminal equipment determines whether a first networking mode is supported or not; the terminal device sends a capability message to a network device, wherein the capability message is used for indicating capability information of the terminal device, and if the terminal device supports the first networking mode, the capability message comprises first information which is used for indicating that the terminal device supports the first networking mode.
The method may be performed by a second communication device, which may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, but may also be other communication devices, such as a system-on-chip. Here, the second communication apparatus is exemplified as a terminal device.
With reference to the second aspect, in a first possible implementation manner of the second aspect, the capability message includes a first capability unit, the first capability unit is used to indicate capability information of a first radio access technology of the terminal device, and the first capability unit includes the first information.
With reference to the first possible implementation manner of the second aspect, in a second possible implementation manner of the second aspect, the first information indicates a core network capability of the first networking mode supported by the terminal device.
With reference to the second aspect, in a third possible implementation manner of the second aspect, if the terminal device does not support the first networking mode, the capability message does not include the first information.
With reference to the second aspect, in a fourth possible implementation manner of the second aspect, if the terminal device does not support the first networking mode, the capability message includes second information, where the second information is used to indicate that the terminal device does not support the first networking mode.

With regard to the technical effects brought by the second aspect or the various embodiments of the second aspect, reference may be made to the introduction of the technical effects of the first aspect or the various embodiments of the first aspect, and details are not repeated.
In a third aspect, a second capability information receiving method is provided, where the method includes: the method comprises the steps that network equipment receives a capability message from terminal equipment, wherein the capability message is used for indicating capability information of the terminal equipment; the capability message includes a first capability unit, the network device determines that the terminal device supports a first networking mode, the first capability unit is used for indicating capability information of the first networking mode, and the first networking mode is a networking mode in which the terminal device is connected with an enhanced long term evolution base station and the enhanced long term evolution base station is connected with a fifth generation core network.
The method may be performed by a third communication device, which may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, but may also be other communication devices, such as a system-on-chip. Here, the third communication apparatus is exemplified as a network device.
In this embodiment of the application, a relatively direct manner may be adopted, that is, a structure of the capability message is changed, a first capability unit is newly added in the capability message, where the first capability unit is, for example, an lte container (or a UE-eutra-capability field), and the newly added first capability unit may be used to carry capability information of the terminal device in an lte independent networking manner. If the terminal device supports the eLTE independent networking mode, the terminal device loads the capability information of the terminal device in the eLTE independent networking mode in the newly added first capability unit and sends the capability information to the network device, and if the terminal device does not support the eLTE independent networking mode, the capability information sent by the terminal device does not include the first capability unit, or the capability information also includes the first capability unit, but the first capability unit is empty. After the network device receives the capability information, if the capability information includes the first capability unit, the network device may determine that the terminal device supports the eLTE independent networking mode, and if the capability information does not include the first capability unit or the first capability unit included in the capability information is empty, the network device may determine that the terminal device does not support the eLTE independent networking mode. By the method, whether the terminal equipment supports the eLTE independent networking mode or not can be simply and directly indicated.
With reference to the third aspect, in a first possible implementation manner of the third aspect, the method further includes: if the first capability unit includes first information, the network device determines that the terminal device supports the second networking mode, and the first information is used for indicating the second networking mode supported by the terminal device.
The first capability unit may indicate whether the terminal device supports the first networking mode, and may also indicate whether the terminal device supports the second networking mode through the included first information. For example, the second networking mode may be an LTE independent networking mode, or may be an NR independent networking mode, or may be an NGEN-DC networking mode. Therefore, more information can be indicated through one capacity unit, and the utilization rate of the first capacity unit is improved.
With reference to the first possible implementation manner of the third aspect, in a second possible implementation manner of the third aspect, the method further includes: if the first capability unit does not include the first information, the network device determines that the terminal device does not support the second networking mode.

In this way, the indication is relatively simple and the overhead of the capability message can be saved to a certain extent. When the indication is performed in this way, the content of the first information does not need to be limited, for example, the first information may be information additionally added to the first capability unit, may be special indication information, or the first information may also be information already existing in the first capability unit, and is not limited specifically.

In this case, the first information and the second information may be regarded as indication information, and it may be understood that the terminal device carries the indication information in the first capability unit, and indicates whether the terminal device supports the second networking mode by an explicit indication mode. For example, whether the indication information is the first information or the second information can be distinguished by different values of the indication information, if the value of the indication information is the first value, the indication information is specifically the first information, which indicates that the terminal device supports the second networking mode, and if the value of the indication information is the second value, the indication information is specifically the second information, which indicates that the terminal device does not support the second networking mode; alternatively, whether the indication information is the first information or the second information may be distinguished by different information, for example, if the content of the indication information is the first content, the indication information is the first information, and if the content of the indication information is the second content, the indication information is the second information. The specific implementation of the indication information is not limited.

4) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "plurality" means two or more, and in view of this, a plurality is also understood as "at least two", for example, two, three or more, in the embodiments of the present application. "at least one" means one, two, three or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified.

Having described some concepts related to embodiments of the present application, the following description will be made of the features of embodiments of the present application, and the following description will be made in detail with reference to fig. 1.
Fig. 1 is a schematic flow chart of the present terminal device transmitting capability information to a network device, the capability information may be wireless access capability information of the terminal device, and the steps of fig. 1 include S11 and S12, which are described in detail below. It should be noted that, the steps described in fig. 1 mainly refer to a signaling flow between the terminal device and the network device, and omit a signaling flow between the network device and the core network.
S11: when the network device sends a UE capability request message to the terminal device, the terminal device receives the UE capability request message from the network device, where the UE capability request message is used to request the terminal device to send radio access capability information of the terminal device in a certain Radio Access Technology (RAT).
The UE capability request message may indicate that one or more RATs (e.g., one or more of E-UTRA technology, NR technology, E-UTRA-NR) indicate that capability information of the terminal device under the RAT is requested.
For example, the UE capability request message is a UE capability query (UE capability inquiry) message.
For a terminal device in a connected state, when the core network device needs the capability information of the terminal device and the core network device does not store the capability information of the terminal device, the core network device may trigger the network device to initiate a UE capability request process, that is, initiate the flow shown in fig. 1 to request the capability information of the terminal device. After the network device initiates a request, the terminal device sends the capability information of the terminal device to the network device, and the network device further sends the capability information of the terminal device to the core network device, so that the network device or the core network device configures or schedules the terminal device according to the capability of the terminal device. In different communication systems, the core network device referred to herein may correspond to different devices, for example, in a 4G system, the core network device referred to herein may be a Mobility Management Entity (MME), and in a 5G NR system, the core network device referred to herein may be an access and mobility management function (AMF).
S12: and the terminal equipment sends the UE capability message to the network equipment, and the network equipment receives the UE capability message from the terminal equipment.
The UE capability message carries radio access capability information of the terminal device, for example, a certain RAT(s) is included in a UE capability request message sent by the network device, if the terminal device supports the RAT(s), the terminal device needs to include a capability container (container) of the RAT(s) in the UE capability message, the container of the RAT(s) includes capability information of the RAT(s), and a RAT type parameter in the container is set to the RAT. For example: the capability information of E-UTRA-NR is requested in the UE capability request message, if the terminal equipment supports EN-DC, the terminal equipment needs to include the capability information of E-UTRA-NR in the UE capability message, and the RAT type parameter in the UE capability message is set to eutra-NR.
The UE capability message is implemented by, for example, a UE capability information (UE capability information) message, and may be a message dedicated to reporting capability information of a terminal device, and the UE capability message may include capability information of at least one radio access technology of the terminal device. The wireless access capability information of the terminal device may include, for example: PDCP parameters, physical layer parameters, radio frequency parameters, measurement parameters, and the like, where the capability parameters specifically correspond to capability information such as a frequency band combination (bandcombination), a supported carrier aggregation bandwidth class (ca-bandwidthclass), and a modulation and coding scheme (modulation and coding scheme). The capability parameters or the capability information are exemplary capability parameters or capability information, and specific and complete capability information is not described herein again in this embodiment of the present application.
After receiving the UE capability message, the network device may configure PDCP configuration, physical layer configuration, radio frequency configuration, measurement configuration, and the like of the terminal device according to specific parameters of the radio access capability information, so as to ensure that the configuration of the terminal device can meet the capability of the terminal device itself, that is, the terminal device can normally operate under the configuration of the network device.
As described in the process shown in fig. 1, the network device sends a UE capability request message to the terminal device, requesting capability information of one or more RATs of the terminal device, and the terminal device needs to report the capability information of the one or more RATs of the terminal device in the UE capability message. When the terminal device sends the capability information of the terminal device to the network device (e.g., a base station), the terminal device divides the capability information into different parts according to the RATs in the UE capability request message and sends the parts in corresponding fields, for example, the terminal device may place the capability information of the terminal device under E-UTRA in the UE-EUTRA-capability field, place the capability information under NR in the UE-NR-capability field included in the UE capability request message and send the capability information under MR-DC in the UE-MRDC-capability field included in the UE capability request message.
Currently, two broad categories of networking modes, independent networking and non-independent networking, are defined for 5G NR. In the independent networking mode of the 5G NR, an end-to-end all-new network of the 5G system needs to be deployed, including a new access network (e.g., NR gbb) and a new core network (next generation core), and the 5G system independently carries a complete control plane and a complete user plane, so that the 5G system can independently operate without depending on the LTE system and independently provide communication services for the terminal device. In a non-independent networking mode, the 5G system needs to rely on the existing LTE system, that is, the NR system and the LTE system need to cooperate with each other to work, for example, an MR-DC mode is adopted, and the NR base station and the LTE base station are connected with the terminal device at the same time to provide communication service for the terminal device together. In the LTE system, the access network part may be referred to as E-UTRA, i.e. a mobile communication wireless network in LTE, and the E-UTRA may be regarded as an air interface technology of LTE to some extent. The E-UTRA comprises the E-UTRA, the terminal equipment and the eNodeB.
Specifically, the independent networking mode includes several specific modes, which are an LTE independent networking mode, and an NR independent networking mode, where the LTE independent networking mode refers to a networking mode in which a terminal device accesses an E-UTRA base station and the E-UTRA base station is connected to a 4G core network, the LTE independent networking mode refers to a networking mode in which the terminal device accesses an enhanced E-UTRA base station and the enhanced E-UTRA base station is connected to a 5G core network, and the NR independent networking mode refers to a networking mode in which the terminal device accesses an NR base station and the NR base station is connected to a 5G core network, with reference to fig. 2B. The non-independent networking mode also includes several specific modes, which are an EN-DC networking mode, an NGEN-DC networking mode, and an NE-DC networking mode, where the EN-DC networking mode refers to fig. 2D, which means that the E-UTRA base station is a main base station, the NR base station is an auxiliary base station, and the E-UTRA base station is connected to the networking mode of the 4G core network, and the NGEN-DC networking mode refers to fig. 2E, which means that the E-UTRA base station is a main base station, the NR base station is an auxiliary base station, and the E-UTRA base station is connected to the networking mode of the 5G core network, and the NE-DC networking mode refers to fig. 2F, which means that the NR base station is a main base station, the E-UTRA base station is an auxiliary base station, and the NR base station is connected to the networking mode of the 5G core network.
There may be a class of terminal devices, which may support one or more of the above six networking modes, and the terminal device needs to report the relevant capability information to the base station according to the supported networking mode. For example, the terminal device may report the capability information of the terminal device to the network device through the UE capability message in S12, where the UE capability message includes three parts: the terminal equipment comprises an E-UTRA capacity part (carried by E-UTRA container), an NR capacity part (carried by NR container) and an MR-DC capacity part (carried by MRDC container), and the terminal equipment divides the capacity information of the terminal equipment into the three parts for reporting. However, the terminal device only reports the capability information of each part, and the network device cannot clearly know the networking mode specifically supported by the terminal device, which may cause the network device to erroneously configure the terminal device.
In view of this, in the embodiment of the present application, the terminal device may indicate, through the capability message, whether the terminal device supports the first networking mode, for example, the capability message includes the first information, which indicates that the terminal device supports the first networking mode, so that the network device can make explicit the networking mode actually supported by the terminal device through the indication, so as to reasonably configure or schedule the terminal device.

The network device is, for example, a base station.
For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the first communication apparatus is a network device and the second communication apparatus is a terminal device as an example. Since the technical solution provided by the present embodiment is applied to the network architecture shown in fig. 3A or fig. 3B as an example, when the present embodiment is applied to the network architecture shown in fig. 3A, the network device described below may be a network device in the network architecture shown in fig. 3A, and the terminal device described below may be a terminal device in the network architecture shown in fig. 3A, whereas when the present embodiment is applied to the network architecture shown in fig. 3B, the network device described below may be an E-UTRA network device in the network architecture shown in fig. 3B, for example, a first network device in the network architecture shown in fig. 3B, and the terminal device described below may be a terminal device in the network architecture shown in fig. 3B.
S41, the terminal equipment determines whether the first networking mode is supported;
s42, a terminal device sends a capability message to a network device, where the network device receives the capability message from the terminal device, and the capability message is used to indicate capability information of the terminal device, where if the terminal device supports the first networking mode, the capability message includes first information, and the first information is used to indicate that the terminal device supports the first networking mode;
s43, if the capability message includes first information, the network device determines that the terminal device supports the first networking mode, where the first information is used to indicate the first networking mode supported by the terminal device.
In S42, the capability message sent by the terminal device to the network device may be implemented by, for example, the UE capability message in the flow shown in fig. 1, and then before S42, the network device may further send a UE capability request message to the terminal device, that is, S11 in the flow shown in fig. 1 may also be performed, which is not limited in particular.
The number of the first networking modes can be one or more. For example, the number of the first networking modes is 1, and for example, the first networking mode may be an LTE independent networking mode or may be an LTE independent networking mode. Or, the number of the first networking modes is greater than 1, that is, the number of the first networking modes is multiple, for example, the number of the first networking modes is 2, one of the first networking modes may be an LTE independent networking mode, and the other first networking mode may be an LTE independent networking mode. Of course, the first networking mode may be another networking mode.
The number of the first information may be one or more. If the terminal device supports a first networking mode, the number of the first information may be one. If the terminal device supports multiple first networking modes, the number of the first information may be one, and one first information indicates various first networking modes supported by the terminal device, for example, the first information may be enumeration-type information, and different first networking modes are indicated by different values of the enumeration-type first information, for example, if the value of the first information is a first value, it indicates that the first networking mode supported by the terminal device is an LTE independent networking mode, if the value of the first information is a second value, it indicates that the first networking mode supported by the terminal device is an LTE independent networking mode, and if the value of the first information is a third value, it indicates that the first networking mode supported by the terminal device is an LTE networking mode and an LTE networking mode, and so on. Or, if the terminal device supports multiple first networking modes, the number of the first information may also be multiple, for example, the number of the first information is the same as the number of the first networking modes, the first information and the first networking modes may be in a one-to-one correspondence relationship, and one first information may indicate one first networking mode.
For example, the number of the first networking modes is 2, one of the first networking modes is an LTE independent networking mode, and the other one of the first networking modes is an LTE independent networking mode, the number of the first information may also be 2, one of the first information is used for indicating that the terminal device supports the LTE independent networking mode, and the other one of the first information is used for indicating that the terminal device supports the LTE independent networking mode. Or, the number of the first networking modes is 2, and the number of the first information is 1, that is, the terminal device is indicated to support the LTE independent networking mode through one piece of first information, or the terminal device is indicated to support the LTE independent networking mode and the LTE independent networking mode.
In one possible embodiment, the capability message may include a first capability unit indicating capability information of a first radio access technology of the terminal device. If the first radio access technology is E-UTRA, for example, the first capability unit may be LTE container or UE-EUTRA-capability field, and the terminal device sends the capability information of E-UTRA to the network device in the LTE container or UE-EUTRA-capability field of the capability message. The first information may be included in the first capability unit, and the first information may be carried in the LTE container or the UE-EUTRA-capability field, for example, if the first capability unit is the LTE container or the UE-EUTRA-capability field. Or the first information may not be carried in the first capability unit, but may be located in other positions of the capability message, which is not limited in the embodiment of the present application.
The first information indicates that the terminal device supports a first networking mode, including but not limited to the following different indication modes:
as a first possible indication manner of the first information, the first information may directly indicate a first networking manner supported by the terminal device, for example, the first information indicates that the terminal device supports an LTE independent networking manner, or the first information indicates that the terminal device supports an LTE independent networking manner and an LTE independent networking manner.
As a second possible indication manner of the first information, the first information indicates to which first networking manners the terminal device supports handover, and the first networking manner that the terminal device supports handover is the first networking manner supported by the terminal device. That is, the first networking mode supported by the terminal device is indicated by indicating which first networking modes the terminal device can switch to. For example, the first information indicates that the terminal device supports switching to the LTE independent networking mode, which means that the terminal device supports the LTE independent networking mode, or the first information indicates that the terminal device supports switching to the LTE independent networking mode, which means that the terminal device supports the LTE independent networking mode.
As a third possible indication manner of the first information, the first information may indicate a core network capability of the first networking manner supported by the terminal device, and by combining the capability information of the radio access technology supported by the terminal device and the core network capability supported by the terminal device, the core network capability of the first networking manner supported by the terminal device, that is, the first networking manner supported by the terminal device, may be known. The so-called core network capability includes, for example, a 4G core network capability or a 5G core network capability. For example, the terminal device supports E-UTRA, and the first information indicates that the core network capability supported by the terminal device is a 4G core network capability, so that it can be known that the first networking mode supported by the terminal device is an LTE independent networking mode by the terminal device supporting E-UTRA and the 4G core network capability. Or the terminal device supports the E-UTRA, and the first information indicates that the core network capability supported by the terminal device is the 5G core network capability, so that the first networking mode supported by the terminal device can be known to be an eLTE independent networking mode by the terminal device supporting the E-UTRA and the 5G core network capability.
Whether the first information is indicated in any of the above three indication manners may be specified by a protocol, or may be preconfigured by the network device, or may be determined by the terminal device itself and notified to the network device. In addition, in addition to the above three indication modes, the first information may also indicate that the first networking mode is supported by other modes, and the embodiment of the present application is not limited.
In this embodiment of the application, the terminal device may indicate, through the capability message, whether the terminal device supports the first networking mode, for example, may indicate through the first information in the capability message. For the first information, there are several implementations including, but not limited to:
as a first implementation manner of the first information, the capability message includes indication information, where the indication information may specifically be the first information or the second information, and it is understood that the capability message includes either the first information or the second information. For example, the first information is included in the first capability unit, then the second information may also be included in the first capability unit, i.e. the first capability unit either includes the first information or includes the second information. If the indication information is specifically the first information, it indicates that the terminal device supports the first networking mode, and after the network device receives the capability message, if it is determined that the capability message includes the first information but not the second information, the network device may determine that the terminal device supports the first networking mode according to the first information included in the capability information. If the indication information is specifically the second information, it indicates that the terminal device does not support the first networking mode, and after the network device receives the capability message, if it is determined that the capability message includes the second information instead of the first information, the network device may determine that the terminal device does not support the first networking mode according to the second information included in the capability message. The implementation mode is more suitable for the condition that the indication information corresponds to the first networking modes one to one, if the indication information is the first information, the first information corresponds to the first networking modes one to one, and if the indication information is the second information, the second information also corresponds to the first networking modes one to one.
For example, the indication information and the first networking mode are in one-to-one correspondence, and one indication information is used for indicating one first networking mode, so that whether the indication information is the first information or the second information can be distinguished through different values of the indication information. For example, if the value of the indication information is a first value, the indication information is the first information, and if the value of the indication information is a second value, the indication information is the second information. For example, the indication information occupies 1 bit (bit), if the 1 bit takes the value of "1", the indication information is specifically first information indicating that the terminal device supports the first networking mode corresponding to the indication information, and if the 1 bit takes the value of "0", the indication information is specifically second information indicating that the terminal device does not support the first networking mode corresponding to the indication information. Or, whether the indication information is the first information or the second information may also be distinguished by different information, for example, if the content of the indication information is the first content, the indication information is the first information, and if the content of the indication information is the second content, the indication information is the second information, where the bit number occupied by the first content and the bit number occupied by the second content may be the same or different.
In this way, whether the terminal device supports the first networking mode is explicitly indicated through the indication information, which is an explicit indication mode, and the indication is more explicit for the network device.
As a second implementation of the first information, the indication information is not necessarily included in the capability message. In this example, the indication information is the first information. Then, after receiving the capability message, the network device may determine that the terminal device supports the first networking mode if the capability message includes the first information, and after receiving the capability message, the network device may determine that the terminal device supports the first networking mode if the capability message does not include the first information, and after receiving the capability message, the network device may determine that the terminal device does not support the first networking mode if the capability message does not include the first information. The method for indicating that the terminal device does not support the first networking mode by not including the first information may also be regarded as a mode of implicit indication.
This implementation may be applicable to the case where the indication information corresponds to the first networking mode one to one, or to the case where one indication information corresponds to all the first networking modes.
For example, for a first networking mode, if the capability message includes the first information corresponding to the first networking mode, it indicates that the terminal device supports the first networking mode, and if the capability message does not include the first information corresponding to the first networking mode, it indicates that the terminal device does not support the first networking mode.
For another example, one piece of first information is used to indicate all the first networking modes, and different values of the first information may represent different first networking modes. For example, the first information may be enumeration type information, and if the value of the first information is a first value, it indicates that the first networking mode supported by the terminal device is an LTE independent networking mode, if the value of the first information is a second value, it indicates that the first networking mode supported by the terminal device is an LTE independent networking mode, and if the value of the first information is a third value, it indicates that the first networking mode supported by the terminal device is an LTE networking mode and an LTE networking mode, and so on. If the capability message includes the first information, the value of the first information may indicate the corresponding first networking mode, and if the capability message does not include the first information, it indicates that the terminal device does not support the first networking mode.
In a second implementation manner of the first information, the capability message may include the first information or may not include the first information, so that the system overhead can be saved to a certain extent.
As to the above-mentioned several implementations of the first information, which is used may be specified by a protocol or may be determined by the network device itself.
In addition, if the terminal device supports the first networking mode and supports the second networking mode, the capability message may further include third information, where the third information is used to indicate that the terminal device supports the second networking mode. After the network device receives the capability information, if the capability information includes the third information, the network device may determine that the terminal device supports the second networking mode. Taking the first networking mode as an eLTE independent networking mode as an example, the second networking mode can be an NGEN-DC networking mode. For example, the third information may also be located in a first capability unit, such as an LTE container or a UE-EUTRA-capability field. That is, the LTE container or UE-EUTRA-capability field may include first information and third information, where the first information may indicate that the terminal device supports an LTE independent networking mode, and the third information may indicate that the terminal device supports an NGEN-DC networking mode. Therefore, according to the LTE container or the UE-EUTRA-capability field, the network device can determine whether the terminal device supports the first networking mode or not, and also can determine whether the terminal device supports the second networking mode or not so as to better configure or schedule the terminal device.
In this embodiment of the application, the terminal device may indicate, through the capability message, whether the terminal device supports the first networking mode, so that the network device can specify the networking mode actually supported by the terminal device, so as to reasonably configure or schedule the terminal device.
In order to solve the same technical problem, a second capability information sending and receiving method is also provided in the embodiments of the present application, please refer to fig. 5, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 3A or fig. 3B as an example. In the embodiment shown in fig. 4, the structure of the existing capability message, for example, whether the capability message includes the UE-EUTRA-capability field (or LTE container), the UE-NR-capability field (or NRcontainer), and the UE-MRDC-capability field (or MR-DC container), is not changed, thereby facilitating compatibility with the existing protocol. In this embodiment, the structure of the capability message is changed, which will be described in detail later.
The method may be performed by two communication devices, for example, a third communication device and a fourth communication device, where the third communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or the third communication device may be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course, other communication devices such as a system-on-chip may also be used. The same applies to the fourth communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, may also be other communication apparatuses, such as a system on a chip. The third communication device may be a network device, the fourth communication device is a terminal device, or both the third communication device and the fourth communication device are network devices, or both the third communication device and the fourth communication device are terminal devices, or the third communication device is a network device, and the fourth 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 convenience of introduction, in the following, the method is performed by the network device and the terminal device as an example, that is, the third communication device is the network device, and the fourth communication device is the terminal device as an example. Since the technical solution provided by the present embodiment is applied to the network architecture shown in fig. 3A or fig. 3B as an example, when the present embodiment is applied to the network architecture shown in fig. 3A, the network device described below may be a network device in the network architecture shown in fig. 3A, and the terminal device described below may be a terminal device in the network architecture shown in fig. 3A, whereas when the present embodiment is applied to the network architecture shown in fig. 3B, the network device described below may be an E-UTRA network device in the network architecture shown in fig. 3B, for example, a first network device in the network architecture shown in fig. 3B, and the terminal device described below may be a terminal device in the network architecture shown in fig. 3B.
S51, the terminal equipment determines that the first networking mode is supported;
s52, a terminal device sends a capability message to a network device, the network device receives the capability message from the terminal device, the capability message is used for indicating capability information of the terminal device, the capability message comprises a first capability unit, the first capability unit is used for indicating capability information of a first networking mode, the first networking mode is a networking mode that the terminal device is connected with an enhanced long term evolution base station, and the enhanced long term evolution base station is connected with a fifth generation core network;
s53, according to that the capability message includes a first capability unit, the network device determines that the terminal device supports the first networking mode, where the first capability unit is used to indicate capability information of the first networking mode, and the first networking mode is a networking mode in which the terminal device is connected to an enhanced long term evolution base station and the enhanced long term evolution base station is connected to a fifth-generation core network.
Illustratively, the first networking mode is, for example, an lte independent networking mode.
In S52, the capability message sent by the terminal device to the network device may be implemented by, for example, the UE capability message in the flow shown in fig. 1, and then before S52, the network device may further send a UE capability request message to the terminal device, that is, S11 in the flow shown in fig. 1 may also be performed, which is not limited in particular.
In the prior art, the capability message includes an LTE adapter (or a UE-EUTRA-capability field), an MR-DC adapter (or a UE-MRDC-capability field), and an NR adapter (or a UE-NR-capability field), so that the terminal device sends capability information of the terminal device in an LTE independent networking mode and/or an LTE independent networking mode through the LTE adapter (or the UE-EUTRA-capability field), that is, sends capability information of the terminal device in an LTE independent networking mode or an LTE independent networking mode, or sends capability information of the terminal device in the LTE independent networking mode and the LTE independent networking mode. After the network device receives the capability message, if the capability message includes LTE container (or UE-EUTRA-capability field), the network device cannot determine whether the capability information indicates that the terminal device supports an LTE independent networking mode or an LTE independent networking mode. Therefore, in the embodiment shown in fig. 4, the first networking mode supported by the terminal device may be indicated by the first information. In the embodiment of the present application, a more direct solution may be adopted to this, that is, a structure of the capability message is changed, and a container (or a capability field) is added to the capability message, for example, a first capability unit may be added, where the first capability unit is, for example, an lte container (or a UE-eutra-capability field), and the added lte container (or the UE-eutra-capability field) may be used to carry capability information of the terminal device in the lte independent networking mode.
If the terminal device supports the eLTE independent networking mode, the terminal device carries the capability information of the terminal device in the eLTE independent networking mode in an added eLTE container (or UE-eEUTRA-capability field) and sends the capability information to the network device, and if the terminal device does not support the eLTE independent networking mode, the capability message sent by the terminal device may not include the eLTE container (or UE-eEUTRA-capability field) or may include the eLTE container (or UE-eEUTRA-capability field) but the eLTE container (or UE-eEUTRA-capability field) is empty. The lte container (or UE-eutra-capability field) is used to indicate capability information of the lte independent networking mode. After the network device receives the capability information, if the capability information includes the eLTEcontainer (or the UE-eEUTRA-capability field), the network device may determine that the terminal device supports the eLTE independent networking mode, and if the capability message does not include the eLTE container (or the UE-eEUTRA-capability field), or if the eLTE container (or the UE-eEUTRA-capability field) included in the capability message is empty, the network device may determine that the terminal device does not support the eLTE independent networking mode.
By the method, whether the terminal equipment supports the eLTE independent networking mode or not can be simply and directly indicated.
In this embodiment of the application, the first capability unit may be further configured to indicate whether the terminal device supports the second networking mode.
The number of the second networking means may be one or more. Illustratively, the number of the second networking modes is 1, for example, the second networking mode may be an LTE independent networking mode, or may be an NR independent networking mode, or may be an NGEN-DC networking mode. Or, the number of the second networking modes is greater than 1, that is, the number of the second networking modes is multiple, for example, the number of the first networking modes is 2, one of the second networking modes may be an LTE independent networking mode, and the other of the second networking modes may be an NR independent networking mode. For example, the number of the first networking modes is 3, the first second networking mode may be an LTE independent networking mode, the second networking mode may be an NR independent networking mode, and the third second networking mode may be an NGEN-DC networking mode. Of course, the second networking mode may be another networking mode.
For example, the first capability unit may include first information to indicate that the terminal device supports the second networking mode through the first information.
The number of the first information may be one or more. If the terminal device supports a second networking mode, the number of the first information may be one. If the terminal device supports multiple second networking modes, the number of the first information may be one, and one first information indicates various second networking modes supported by the terminal device, for example, the first information may be enumeration-type information, and different second networking modes are indicated by different values of the enumeration-type first information, for example, if the value of the first information is a first value, it indicates that the second networking mode supported by the terminal device is an LTE independent networking mode, if the value of the first information is a second value, it indicates that the second networking mode supported by the terminal device is an NR independent networking mode, if the value of the first information is a third value, it indicates that the second networking mode supported by the terminal device is an LTE networking mode and an NR networking mode, and if the value of the first information is a fourth value, it indicates that the second networking mode supported by the terminal device is an NGEN-DC networking mode, and so on. Or, if the terminal device supports multiple second networking modes, the number of the first information may also be multiple, for example, the number of the first information is the same as the number of the second networking modes, the first information and the second networking modes may be in a one-to-one correspondence relationship, and one first information may indicate one second networking mode.
For example, the number of the second networking modes is 3, the first second networking mode is an LTE independent networking mode, the second networking mode is an NR independent networking mode, the third second networking mode is an NGEN-DC independent networking mode, the number of the first information may also be 3, the first information is used to indicate that the terminal device supports the LTE independent networking mode, the second first information is used to indicate that the terminal device supports the NR independent networking mode, and the third first information is used to indicate that the terminal device supports the NGEN-DC networking mode. Or, the number of the second networking modes is 3, and the number of the first information is 1, that is, which of the second networking modes the terminal device supports is indicated by one first information.
The first information indicates that the terminal device supports the second networking mode, including but not limited to the following different indication modes:
as a first possible indication manner of the first information, the first information may directly indicate a second networking manner supported by the terminal device. For example, the first information indicates that the terminal device supports the LTE independent networking mode, or the first information indicates that the terminal device supports the NR independent networking mode, or the first information indicates that the terminal device supports the LTE independent networking mode and the NR independent networking mode.
As a second possible indication manner of the first information, the first information indicates to which second networking manners the terminal device supports handover, and the second networking manner that the terminal device supports handover is the second networking manner supported by the terminal device. That is, the second networking mode supported by the terminal device is indicated by indicating which second networking modes the terminal device can switch to. For example, the first information indicates that the terminal device supports switching to the LTE independent networking mode, which means that the terminal device supports the LTE independent networking mode, or the first information indicates that the terminal device supports switching to the LTE independent networking mode, which means that the terminal device supports the LTE independent networking mode.
As a third possible indication manner of the first information, the first information may indicate a core network capability of the second networking manner supported by the terminal device, and by combining the capability information of the radio access technology supported by the terminal device and the core network capability supported by the terminal device, the core network capability of the second networking manner supported by the terminal device, that is, the second networking manner supported by the terminal device, may be known. The so-called core network capability includes, for example, a 4G core network capability or a 5G core network capability. For example, the terminal device supports E-UTRA, and the first information indicates that the core network capability supported by the terminal device is a 4G core network capability, so that it can be known that the second networking mode supported by the terminal device is an LTE independent networking mode by the terminal device supporting E-UTRA and the 4G core network capability. Or, the terminal device supports NR, and the first information indicates that the core network capability supported by the terminal device is a 5G core network capability, and it can be known that the second networking mode supported by the terminal device is an NR independent networking mode by the terminal device supporting NR and supporting the 5G core network capability.
Whether the first information is indicated in any of the above three indication manners may be specified by a protocol, or may be preconfigured by the network device, or may be determined by the terminal device itself and notified to the network device. In addition, in addition to the above three indication modes, the first information may also indicate that the second networking mode is supported by other modes, and the embodiment of the present application is not limited.
In this embodiment of the application, the terminal device may indicate, through the capability message, whether the terminal device supports the second networking mode, for example, may indicate through the first information in the first capability unit included in the capability message. For the first information, there are several implementations including, but not limited to:
as a first implementation manner of the first information, the capability message includes indication information, where the indication information may specifically be the first information or the second information, and it is understood that the capability message includes either the first information or the second information. For example, the first information is included in the first capability unit, then the second information may also be included in the first capability unit, i.e. the first capability unit either includes the first information or includes the second information. If the indication information is specifically the first information, it indicates that the terminal device supports the second networking mode, and after the network device receives the capability message, if it is determined that the capability message includes the first information but not the second information, the network device may determine that the terminal device supports the second networking mode according to the first information included in the capability information. If the indication information is specifically the second information, it indicates that the terminal device does not support the second networking mode, and after the network device receives the capability message, if it is determined that the capability message includes the second information instead of the first information, the network device may determine that the terminal device does not support the second networking mode according to the second information included in the capability message. The implementation mode is more suitable for the condition that the indication information and the second networking mode are in one-to-one correspondence, if the indication information is the first information, the first information and the second networking mode are in one-to-one correspondence, and if the indication information is the second information, the second information and the second networking mode are in one-to-one correspondence.
For example, the indication information and the second networking mode are in one-to-one correspondence, and one indication information is used for indicating one second networking mode, so that whether the indication information is the first information or the second information can be distinguished through different values of the indication information. For example, if the value of the indication information is a first value, the indication information is the first information, and if the value of the indication information is a second value, the indication information is the second information. For example, the indication information occupies 1 bit, if the 1 bit takes the value of "1", the indication information is specifically first information indicating that the terminal device supports the second networking mode corresponding to the indication information, and if the 1 bit takes the value of "0", the indication information is specifically second information indicating that the terminal device does not support the second networking mode corresponding to the indication information. Or, whether the indication information is the first information or the second information may also be distinguished by different information, for example, if the content of the indication information is the first content, the indication information is the first information, and if the content of the indication information is the second content, the indication information is the second information, where the bit number occupied by the first content and the bit number occupied by the second content may be the same or different.
In this way, whether the terminal device supports the second networking mode is explicitly indicated through the indication information, which is an explicit indication mode, and the indication is more explicit for the network device.
As a second implementation of the first information, the indication information is not necessarily included in the capability message. In this example, the indication information is the first information. Then, after receiving the capability message, the network device may determine that the terminal device supports the second networking mode if the capability message includes the first information, and after receiving the capability message, the network device may determine that the terminal device supports the second networking mode if the capability message does not include the first information, and after receiving the capability message, the network device may determine that the terminal device does not support the second networking mode if the capability message does not include the first information. The manner of indicating that the terminal device does not support the second networking manner by not including the first information may also be regarded as a manner of implicit indication.
The implementation mode can be suitable for the condition that the indication information corresponds to the second networking modes one by one, and can also be suitable for the condition that one indication information corresponds to all the second networking modes.
For example, for a second networking mode, if the capability message includes the first information corresponding to the second networking mode, it indicates that the terminal device supports the second networking mode, and if the capability message does not include the first information corresponding to the second networking mode, it indicates that the terminal device does not support the second networking mode.
For another example, one piece of first information is used to indicate all the second networking modes, and different values of the first information may represent different second networking modes. For example, the first information may be enumeration type information, and if the value of the first information is a first value, it indicates that the second networking mode supported by the terminal device is an LTE independent networking mode, if the value of the first information is a second value, it indicates that the second networking mode supported by the terminal device is an NR independent networking mode, if the value of the first information is a third value, it indicates that the second networking mode supported by the terminal device is an LTE networking mode and an NR networking mode, and if the value of the first information is a third value, it indicates that the second networking mode supported by the terminal device is an LTE networking mode and an NGEN-DC networking mode, and so on. If the capability message includes the first information, the value of the first information may indicate the corresponding second networking mode, and if the capability message does not include the first information, it indicates that the terminal device does not support the second networking mode.
In a second implementation manner of the first information, the capability message may include the first information or may not include the first information, so that the system overhead can be saved to a certain extent.
As to the above-mentioned several implementations of the first information, which is used may be specified by a protocol or may be determined by the network device itself.
In the embodiment of the application, the terminal device can indicate whether the terminal device supports the eLTE independent networking capability through the newly added first capability unit, so that the network device can determine whether the terminal device supports the LTE independent networking capability and the eLTE independent networking capability respectively, and the capability of the terminal device is prevented from being confused. And the capability message can also indicate whether the terminal equipment supports the second networking mode, so that the network equipment can clearly determine the networking mode actually supported by the terminal equipment to reasonably configure or schedule the terminal equipment.
In order to solve the same technical problem, an embodiment of the present application further provides a capability information sending and receiving method, please refer to fig. 6, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 3A or fig. 3B as an example. In the embodiment shown in fig. 4, the structure of the existing capability message, for example, whether the capability message includes the UE-EUTRA-capability field (or LTE container), the UE-NR-capability field (or NRcontainer), and the UE-MRDC-capability field (or MR-DC container), is not changed, thereby facilitating compatibility with the existing protocol. In the embodiment shown in fig. 5, the structure of the capability message is changed, and the UE-eutra-capability field (or lte container) is newly added. The scheme provided by the embodiment can be applied to a scene without changing the existing capability message structure, and can also be applied to a scene with changing the existing capability message structure.
The method may be performed by two communication apparatuses, for example, a fifth communication apparatus and a sixth communication apparatus, where the fifth communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the fifth communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may also be other communication apparatuses, such as a system on a chip. The same is true for the sixth communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the sixth communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, or of course, other communication apparatuses such as a system on chip may also be used. The fifth communication device and the sixth communication device are not limited to be implemented, for example, the fifth communication device may be a network device, the sixth communication device is a terminal device, or both the fifth communication device and the sixth communication device are network devices, or both the fifth communication device and the sixth communication device are terminal devices, or the fifth communication device is a network device, and the sixth 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 convenience of introduction, in the following, the method is performed by the network device and the terminal device as an example, that is, the fifth communication device is the network device, and the sixth communication device is the terminal device as an example. Since the technical solution provided by the present embodiment is applied to the network architecture shown in fig. 3A or fig. 3B as an example, when the present embodiment is applied to the network architecture shown in fig. 3A, the network device described below may be a network device in the network architecture shown in fig. 3A, and the terminal device described below may be a terminal device in the network architecture shown in fig. 3A, whereas when the present embodiment is applied to the network architecture shown in fig. 3B, the network device described below may be an E-UTRA network device in the network architecture shown in fig. 3B, for example, a first network device in the network architecture shown in fig. 3B, and the terminal device described below may be a terminal device in the network architecture shown in fig. 3B.
S61, the terminal equipment determines that the first networking mode is supported;
s62, the terminal device sends a capability message to a network device, where the network device receives the capability message from the terminal device, and the capability message is used to indicate capability information of the terminal device, where the capability message includes a first capability unit and a second capability unit, the first capability unit is used to indicate capability information of a first radio access technology of the terminal device, and the second capability unit is used to indicate capability information of a multi-access technology dual connection of the terminal device;
s63, according to that the capability message includes a first capability unit and a second capability unit, the network device determines that the terminal device supports a first networking mode, where the first capability unit is used to indicate capability information of a first radio access technology of the terminal device, and the second capability unit is used to indicate capability information of a multi-access technology dual connection of the terminal device.
For example, if the first radio access technology is lte, the first networking mode is an NGEN-DC networking mode, in this case, the embodiment may be applied to the scenario that the structure of the capability message is changed in the embodiment shown in fig. 5, and then the first capability unit is lte container (or UE-eutra-capability field), for example. The second capability unit indicates, for example, capability information of MR-DC of the terminal device, and the second capability unit is, for example, a UE-MRDC-capability field (or MR-DC container). That is, if the terminal device supports the NGEN-DC networking mode, the terminal device may send a capability message including an eLTE container (or a UE-eEUTRA-capability field and a UE-MRDC-capability field (or an MR-DC container)), if the terminal device sends a capability message including both an eLTE container (or a UE-eEUTRA-capability field) and a UE-MRDC-capability field (or an MR-DC container), it may indicate that the terminal device supports the NGEN-DC networking mode, after the network device receives the capability message, if it determines that the eLTE container (or the UE-eEUTRA-capability field) and the UE-MRDC-capability field (or the MR-DC container) are included in the capability message, it may determine that the terminal device supports the NGEN-DC networking mode, and if it determines that the UE-MRDC-capability field (or the MR-DC container) are not included in the capability message, it can be determined that the end device does not support the NGEN-DC networking approach.
Or, if the first radio access technology is NR, for example, the first networking mode is NE-DC networking mode, and in this case, no matter the present embodiment is applied in the scenario that the structure of the capability message is not changed in the embodiment shown in fig. 4, or the present embodiment is applied in the scenario that the structure of the capability message is changed in the embodiment shown in fig. 4, the first capability unit is NR container (or UE-NR-capability field), for example. The second capability unit indicates, for example, capability information of MR-DC of the terminal device, and the second capability unit is, for example, a UE-MRDC-capability field (or MR-dccontiner). That is, if the terminal device supports the NE-DC networking mode, the capability message sent by the terminal device may include an NR container (or UE-NR-capability field) and a UE-MRDC-capability field (or MR-DCcontainer). If the capability message sent by the terminal device includes both the NR container (or UE-NR-capability field) and the UE-MRDC-capability field (or MR-DC container), it may indicate that the terminal device supports the NE-DC networking mode. After the network device receives the capability message, if the capability message is determined to include the NR container (or UE-NR-capability field) and the UE-MRDC-capability field (or MR-DC container), it may be determined that the terminal device supports the NE-DC networking mode, and if the capability message is determined to not include the UE-MRDC-capability field (or MR-DC container), it may be determined that the terminal device does not support the NE-DC networking mode.
The embodiment is an implicit indication mode, does not need special indication information, and is beneficial to saving transmission resources.
