Description

一种发送、接收能力信息的方法及装置Method and device for transmitting and receiving capability information 技术领域Technical field
本申请涉及通信技术领域，尤其涉及一种发送、接收能力信息的方法及装置。The present application relates to the field of communication technologies, and in particular, to a method and device for transmitting and receiving capability information.
背景技术Background technique
终端设备在接入某一网络之后，需要向基站以及核心网设备上报终端设备的能力信息。终端设备所上报的能力信息，可以包含该终端设备的多种无线接入技术(radio access technology，RAT)的能力信息，例如包含该终端设备新无线技术(new radio，NR)和演进的通用移动通信系统陆地无线接入技术(evolved-UMTS terrestrial radio access，E-UTRA)等RAT的能力信息。After the terminal equipment accesses a certain network, it needs to report the capability information of the terminal equipment to the base station and the core network equipment. The capability information reported by the terminal device may include the capability information of multiple wireless access technologies (RATs) of the terminal device, such as the new wireless technology (NR) of the terminal device and the evolved universal mobile Capability information of RATs such as evolved-UMTS terrestrial radio access (E-UTRA) in communication systems.
随着标准的演进，在Release8之后又引入了Release 9、Release 10、Release 11、Release 12、Release13、Release 14以及现在正在标准化的Release 15等版本，另外在每个Release里面又包括不同的版本，如Release 9中包括v920、v940，以及v9a0、v9c0、v9d0、v9e0和v9h0等版本。每一个版本都会引入新的能力信息，也就是说，每个新版本的终端设备除了具有老版本的终端设备所具有的能力信息外，还具有老版本的终端设备所不具有的新的能力信息，那么对于新版本的终端设备来说，就需要上报老版本的终端设备所具有的能力信息，以及新版本所引入的新的能力信息。With the evolution of the standard, Release 9, 9, Release 10, Release 11, 11, Release 12, Release 13, Release 14, and Release 15, which are now being standardized, are introduced after Release 8. In addition, different versions are included in each Release. For example, Release 9 includes v920, v940, and v9a0, v9c0, v9d0, v9e0, and v9h0. Each version introduces new capability information, that is, each new version of the terminal device has, in addition to the capability information of the old version of the terminal device, new capability information that the old version of the terminal device does not have. , Then for a new version of the terminal device, it is necessary to report the capability information of the old version of the terminal device and the new capability information introduced by the new version.
而按照目前的方式，终端设备需要上报的所有能力信息都必须放在一条消息中上报给网络设备，该消息是一条不可拆分的、完整的消息，该消息例如为无线资源控制(radio resource control，RRC)消息，其中，RRC消息是承载在分组数据汇聚协议(packet data convergence protocol，PDCP)服务数据单元(service data unit，SDU)中发送。在长期演进(long term evolution，LTE)系统中，一个PDCP SDU最大的容量为8188字节(bytes)，在NR系统中，一个PDCP SDU最大的容量为9000bytes。随着Release15以及进一步的版本的逐渐演进，终端设备需要上报的能力信息会包括越来越多的内容，很有可能会超过PDCP SDU的最大容量。一旦终端设备需要上报的能力信息超过了PDCP SDU的最大容量，则无法将其放入PDCP SDU中，从而导致终端设备无法正确上报终端设备的能力信息。According to the current method, all the capability information that the terminal device needs to report must be reported to the network device in a message. The message is an indivisible and complete message, such as radio resource control (radio resource control). (RRC) message, where the RRC message is carried in a packet data convergence protocol (packet data convergence protocol (PDCP) service data unit (SDU)) and sent. In a long term evolution (LTE) system, the maximum capacity of a PDCP SDU is 8188 bytes (bytes), and in a NR system, the maximum capacity of a PDCP SDU is 9000 bytes. With the gradual evolution of Release15 and further versions, the capability information that terminal devices need to report will include more and more content, which is likely to exceed the maximum capacity of PDCP and SDU. Once the capability information that the terminal device needs to report exceeds the maximum capacity of the PDCP SDU, it cannot be placed in the PDCP SDU, resulting in the terminal device not being able to correctly report the capability information of the terminal device.

以N个能力消息包括第一能力消息和第二能力消息为例，其中，第一能力消息和第二能力消息可以是N个能力消息中的全部能力消息，即，N＝2，或者，第一能力消息和第二能力消息也可以是N个能力消息中的部分能力消息，则N>2。例如，终端设备将终端设备的不同版本的能力信息放在多个能力消息中发送，则第一能力消息包括的终端设备的部分能力信息可以是终端设备的至少一个版本的能力信息，第一能力消息包括的终端设备的部分能力信息也可以是终端设备的至少一个版本的能力信息，第一能力消息对应的版本与第二能力消息对应的版本可以不同；或者，终端设备将终端设备的不同的无线接入技术的能力信息放在多个能力消息中发送，则第一能力消息包括的终端设备的部分能力信息可以是终端设备的至少一种无线接入技术的能力信息，第一能力消息包括的终端设备的部分能力信息也可以是终端设备的至少一种无线接入技术的能力信息，第一能力消息对应的无线接入技术与第二能力消息对应的无线接入技术可以不同；或者，终端设备将终端设备的完整能力信息进行编码，再将编码后的能力信息分割为至少两个部分，将其中的一个部分放入一个能力消息中，则第一能力消息会包括终端设备的部分能力信息，第二能力消息也会包括终端设备的部分能力信息，第一能力消息包括的能力信息与第二能力消息包括的能力信息可以不同。如上只是举例，对于终端设备划分能力信息的方式不作限制。Take the N capability messages including the first capability message and the second capability message as an example, where the first capability message and the second capability message may be all the capability messages among the N capability messages, that is, N = 2, or The first capability message and the second capability message may also be part of the N capability messages, so N> 2. For example, the terminal device sends capability information of different versions of the terminal device in multiple capability messages, and then part of the capability information of the terminal device included in the first capability message may be capability information of at least one version of the terminal device. The first capability Part of the capability information of the terminal device included in the message may also be capability information of at least one version of the terminal device, and the version corresponding to the first capability message may be different from the version corresponding to the second capability message; or, the terminal device may The capability information of the radio access technology is sent in multiple capability messages, and then part of the capability information of the terminal device included in the first capability message may be capability information of at least one radio access technology of the terminal device. The first capability message includes Part of the capability information of the terminal device may also be capability information of at least one radio access technology of the terminal device. The radio access technology corresponding to the first capability message and the radio access technology corresponding to the second capability message may be different; or, The terminal device encodes the complete capability information of the terminal device, Divide the encoded capability information into at least two parts, and put one of them into a capability message. The first capability message will include some of the terminal device's capability information, and the second capability message will also include the terminal device's part. Capability information, the capability information included in the first capability message and the capability information included in the second capability message may be different. The above is just an example, and there is no limitation on the manner in which the terminal equipment divides the capability information.
结合第一方面的第一种可能的实施方式，在第一方面的第二种可能的实施方式中，所述第一能力消息包括第一指示信息，所述第一指示信息指示所述终端设备的第一部分能力信息在所述第二能力消息中发送，或者，所述第一指示信息指示所述终端设备的第一部分能力信息在所述第一能力消息中发送。With reference to the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the first capability message includes first indication information, and the first indication information indicates the terminal device The first part of the capability information is sent in the second capability message, or the first indication information indicates that the first part of the capability information of the terminal device is sent in the first capability message.
因为终端设备将能力信息放在N个能力消息中发送，那么终端设备就需要指示能力信息究竟在哪个能力消息中发送，以便网络设备接收能力消息后，能够根据获得的能力信息得到终端设备的完整能力信息。在这种实施方式中，终端设备可以通过第一指示信息来指示，无论第一部分能力信息是在第一能力消息中发送还是在第二能力消息中发送，第一能力消息都可以包括第一指示信息，网络设备接收了第一能力消息，根据第一指示信息就可以确定第一部分能力消息究竟是在第一能力消息中发送还是在其他能力消息中发送，从而使得网络设备能够正确地获得第一部分能力信息。Because the terminal device sends the capability information in N capability messages, the terminal device needs to indicate in which capability message the capability information is sent, so that the network device can obtain the completeness of the terminal device according to the acquired capability information after receiving the capability message. Capability information. In this embodiment, the terminal device may indicate through the first indication information, and the first capability message may include the first indication whether the first part of the capability information is sent in the first capability message or the second capability message. Information, the network device receives the first capability message, and according to the first indication information, it can be determined whether the first part of the capability message is sent in the first capability message or in another capability message, so that the network device can correctly obtain the first part Capability information.
结合第一方面的第二种可能的实施方式，在第一方面的第三种可能的实施方式中，所述第一指示信息的取值为第一值，指示所述终端设备的第一部分能力信息在所述第二能力消息中发送，或者，所述第一指示信息的取值为第二值，指示所述终端设备的第一部分能力信息在所述第一能力消息中发送。With reference to the second possible implementation manner of the first aspect, in a third possible implementation manner of the first aspect, the value of the first indication information is a first value, which indicates a first part capability of the terminal device The information is sent in the second capability message, or the value of the first indication information is a second value, indicating that the first part of the capability information of the terminal device is sent in the first capability message.
无论一个能力消息是包括第一部分能力信息还是不包括第一部分能力信息，该能力消息都可以包括第一指示信息，那么显然，第一指示信息指示的是不同的内容，因此在本申请实施例中，第一指示信息可以通过取值的不同来指示不同的内容。例如第一指示信息可通过布尔类型或枚举类型等实现，通过两个取值来指示两种的内容。通过这种方式，能够较为清楚地指示第一部分能力信息究竟包括在哪个能力消息中，且方式较为简单。Whether a capability message includes the first part of capability information or does not include the first part of capability information, the capability message may include the first indication information. Obviously, the first indication information indicates different content. Therefore, in the embodiment of the present application, The first indication information may indicate different contents by different values. For example, the first indication information may be implemented by using a Boolean type or an enumeration type, and two types of values are used to indicate two types of content. In this way, the capability information of the first part of the capability information can be clearly indicated, and the manner is relatively simple.
结合第一方面的第一种可能的实施方式，在第一方面的第四种可能的实施方式中，所述第一能力消息包括第一指示信息，指示所述终端设备的第一部分能力信息在所述第二能力消息中发送；或者，所述第一能力消息不包括所述第一指示信息，指示所述终端设备的第一部分能力信息在所述第一能力消息中发送。With reference to the first possible implementation manner of the first aspect, in a fourth possible implementation manner of the first aspect, the first capability message includes first indication information, indicating that the first part of the capability information of the terminal device is Sent in the second capability message; or the first capability message does not include the first indication information, indicating that the first part of the capability information of the terminal device is sent in the first capability message.
结合第一方面的第一种可能的实施方式，在第一方面的第五种可能的实施方式中，所述第一能力消息包括第一指示信息，指示所述终端设备的第一部分能力信息在所述第一能力消息中发送；或者，所述第一能力消息不包括所述第一指示信息，指示所述终端设备的第一部分能力信息在所述第二能力消息中发送。With reference to the first possible implementation manner of the first aspect, in a fifth possible implementation manner of the first aspect, the first capability message includes first indication information, indicating that the first part of the capability information of the terminal device is in Sent in the first capability message; or the first capability message does not include the first indication information, indicating that the first part of the capability information of the terminal device is sent in the second capability message.
在这两种实施方式中，终端设备还是可以通过第一指示信息来指示能力信息在哪个能力消息中发送，但在这种实施方式中，终端设备是通过一个能力消息是否包括第一指示信息来指示第一部分能力信息究竟在哪个能力消息中发送，这种方式能够减少能力消息所包括的能力消息的数量，且同样能够较为清楚地指示能力信息所在的位置。In these two embodiments, the terminal device can still indicate in which capability message the capability information is sent by using the first indication information. However, in this embodiment, the terminal device determines whether a capability message includes the first indication information. Indicate in which capability message the first part of the capability information is sent. This method can reduce the number of capability messages included in the capability message, and can also clearly indicate where the capability information is located.

在这种方式中，终端设备通过第二指示信息和第三指示信息这两个指示信息来指示能力信息在哪个能力消息中发送，网络设备根据一个能力消息中包括的究竟是第二指示信息还是第三指示信息，就可以确定对应的能力信息是在哪个能力消息中发送。通过两个指示信息来指示，较为清楚，且第二指示信息和第三指示信息的值相同或相关，有助于网络设备根据两个能力消息中的第二指示信息和第三指示信息来索引，从而得到对应的能力信息。In this manner, the terminal device indicates in which capability message the capability information is sent through the two indication information, the second indication information and the third indication information. The network device determines whether the second indication information or the second indication information is included in one capability message. The third indication information can determine in which capability message the corresponding capability information is sent. The indication is performed by two indication information, which is relatively clear, and the values of the second indication information and the third indication information are the same or related, which helps the network device to index according to the second indication information and the third indication information in the two capability messages. To get the corresponding capability information.
结合第一方面的第一种可能的实施方式至第一方面的第六种可能的实施方式中的任一种可能的实施方式，在第一方面的第七种可能的实施方式中，所述第二能力消息包括所述终端设备的第一部分能力信息。With reference to any one of the first possible implementation manner of the first aspect to the sixth possible implementation manner of the first aspect, in a seventh possible implementation manner of the first aspect, the The second capability message includes first part capability information of the terminal device.
在前面介绍了，第一指示信息可能指示第一部分能力信息在第二能力消息中发送，或者第二指示信息也指示第一部分能力信息在第二能力消息中发送，那么，如果第一能力消息包括用于指示第一部分能力信息在第二能力消息中发送的第一指示信息，或第一能力消息包括第二指示信息，也就是第一能力消息不包括第一部分能力信息，则第二能力消息就会包括第一部分能力信息。As described above, the first indication information may indicate that the first part of the capability information is sent in the second capability message, or the second indication information also indicates that the first part of the capability information is sent in the second capability message. Then, if the first capability message includes The first indication information used to indicate that the first part of capability information is sent in the second capability message, or the first capability message includes the second indication information, that is, the first capability message does not include the first part of capability information, and the second capability message is Will include the first part of the capability information.
结合第一方面的第一种可能的实施方式至第一方面的第五种可能的实施方式中的任一种可能的实施方式，或结合第一方面的第七种可能的实施方式，在第一方面的第八种可能的实施方式中，所述第二能力消息还包括所述第一指示信息。In combination with any one of the first possible implementation manner of the first aspect to the fifth possible implementation manner of the first aspect, or in combination with the seventh possible implementation manner of the first aspect, in the first In an eighth possible implementation manner of the aspect, the second capability message further includes the first indication information.
对于通过第一指示信息来进行指示的方式，第一能力消息和第二能力消息中都可以包括第一指示信息，网络设备无论接收第一能力消息还是第二能力消息，都可以通过其中包括的第一指示信息确定第一部分能力信息究竟在当前的能力消息中发送还是在其他的能力消息中发送，指示较为清楚。For the manner of indicating by the first indication information, both the first capability message and the second capability message may include the first indication information, and whether the network device receives the first capability message or the second capability message, it may use the included information. The first indication information determines whether the first part of the capability information is sent in the current capability message or in another capability message, and the indication is clear.
结合第一方面的第二种可能的实施方式，在第一方面的第九种可能的实施方式中，所述第一能力消息和所述第二能力消息中均包括指示信息，所述指示信息用于指示所述第一能力消息和所述第二能力消息包括的所述终端设备的能力信息对应的所有无线接入技术，或者，所述指示信息用于指示所述第一能力消息和所述第二能力消息包括的所述终端设备的能力信息对应的所有的版本。With reference to the second possible implementation manner of the first aspect, in a ninth possible implementation manner of the first aspect, both the first capability message and the second capability message include indication information, and the indication information Used to indicate all radio access technologies corresponding to the capability information of the terminal device included in the first capability message and the second capability message, or the indication information is used to indicate the first capability message and all All versions corresponding to the capability information of the terminal device included in the second capability message.
例如，指示信息可以通过列表的形式实现，该列表中例如包括第一能力消息和第二能力消息包括的终端设备的能力信息对应的所有版本的版本标识信息，其中一个版本标识信息对应于终端设备的一个版本，版本标识信息例如为版本的版本号，或者为其他属性信息。或者，该列表中例如包括第一能力消息和第二能力消息包括的终端设备的能力信息对应的所有无线接入技术的RAT标识信息，其中一个RAT标识信息对应于一个无线接入技术，RAT标识信息例如为无线接入技术的名称，或者为其他属性信息。通过这种指示信息，较为简单明了地指示了N个能力消息应该包括的所有的能力信息，网络设备无论接收到哪个能力消息，都能够获得该指示信息，从而使得网络设备较为清楚是否获得了终端设备的完整能力信息。For example, the indication information may be implemented in the form of a list. The list includes, for example, version identification information of all versions corresponding to the capability information of the terminal device included in the first capability message and the second capability message, and one version identification information corresponds to the terminal device. For a version, the version identification information is, for example, the version number of the version, or other attribute information. Alternatively, the list includes, for example, RAT identification information of all radio access technologies corresponding to the capability information of the terminal device included in the first capability message and the second capability message, where one RAT identification information corresponds to one radio access technology and the RAT identifier The information is, for example, the name of the radio access technology, or other attribute information. Through this indication information, all capability information that should be included in the N capability messages is indicated in a relatively simple and clear manner. The network equipment can obtain the indication information no matter which capability message is received, thereby making it more clear whether the network equipment has obtained the terminal. Full capability information for the device.
结合第一方面的第一种可能的实施方式至第一方面的第九种可能的实施方式中的任一种可能的实施方式，在第一方面的第十种可能的实施方式中，所述N个能力消息中每个能力消息分别包括所述终端设 备的至少一个版本的能力信息。With reference to any one of the first possible implementation manner of the first aspect to the ninth possible implementation manner of the first aspect, in a tenth possible implementation manner of the first aspect, the Each of the N capability messages includes capability information of at least one version of the terminal device.
结合第一方面的第一种可能的实施方式至第一方面的第九种可能的实施方式中的任一种可能的实施方式，在第一方面的第十一种可能的实施方式中，所述N个能力消息中每个能力消息分别包括所述终端设备的至少一种无线接入技术的能力信息。In combination with any one of the first possible implementation manner of the first aspect to the ninth possible implementation manner of the first aspect, in the eleventh possible implementation manner of the first aspect, all Each of the N capability messages includes capability information of at least one radio access technology of the terminal device.
也就是说，对于如上的第一方面的第一种可能的实施方式至第一方面的第九种可能的实施方式中的任一种可能的实施方式来说，终端设备可以是按照终端设备的版本将对应的能力信息划分为多个部分，或者可以是按照终端设备的无线接入技术将对应的能力信息划分为多个部分，但这只是举例，具体的划分方式不作限制。That is, for any possible implementation manner from the first possible implementation manner of the first aspect to the ninth possible implementation manner of the first aspect, the terminal device may be a terminal device The version divides the corresponding capability information into multiple parts, or may divide the corresponding capability information into multiple parts according to the wireless access technology of the terminal device, but this is only an example, and the specific division method is not limited.

结合第一方面，在第一方面的第十三种可能的实施方式中，所述能力消息包括指示信息，所述指示信息指示所述能力消息在所述N个能力消息中的序列号，以及指示所述N的取值。With reference to the first aspect, in a thirteenth possible implementation manner of the first aspect, the capability message includes indication information that indicates a sequence number of the capability message in the N capability messages, and Indicates the value of N.
如上的两种指示方式较为简单明确，其中，能力消息的序列号，可以是根据终端设备发送能力消息的顺序为能力消息添加的序列号，或者可以是根据终端设备生成能力消息的顺序为能力消息的序列号，那么网络设备接收能力消息后，根据能力消息的序列号，以及该能力消息是否为N个能力消息中的最后一个能力消息或者N的取值，就可以知道当前的能力消息是N个能力消息中的哪一部分，也可以知道N个能力消息是否都已经接收完毕，从而使得网络设备能够根据N个能力消息所包括的能力信息获得终端设备的完整能力信息，尽量减小网络设备遗漏其中的部分能力信息的可能性。The above two indication methods are relatively simple and clear. The sequence number of the capability message may be a sequence number added to the capability message according to the order in which the terminal device sends the capability message, or may be a capability message according to the order in which the terminal device generates the capability message. Sequence number, then after receiving the capability message, the network device can know that the current capability message is N based on the capability message sequence number and whether the capability message is the last capability message or the value of N. Which part of a capability message can also know whether all N capability messages have been received, so that the network device can obtain the complete capability information of the terminal device according to the capability information included in the N capability messages, and minimize the omission of the network device. Some of these capabilities are possible information.

因为终端设备可能会多次向网络设备发送终端设备的能力信息，那么为了区分不同的发送次数，就可以在能力消息中添加标识信息，一次发送的能力消息包括的标识信息相同，从而通过标识信息可以区分不同的发送次数，网络设备可以根据终端设备一次发送的能力消息来获得终端设备的完整能力信息，尽量避免网络设备将终端设备不同次发送的能力消息进行合并译码，从而导致译码错误或导致获得的能力信息不够准确。Because the terminal device may send the capability information of the terminal device to the network device multiple times, in order to distinguish the different sending times, identification information can be added to the capability message. The capability information sent at one time contains the same identification information, so that the identification information is passed through the identification information. Different sending times can be distinguished. The network device can obtain the complete capability information of the terminal device according to the capability message sent by the terminal device at one time, and try to avoid that the network device combines and decodes the capability message sent by the terminal device at different times, resulting in decoding errors. Or lead to inaccurate ability information.

如上介绍了本申请实施例涉及的一些概念，下面介绍本申请实施例的技术背景，以下结合图1进行详细说明。As described above, some concepts related to the embodiments of the present application are introduced. The technical background of the embodiments of the present application is introduced below, and detailed description is given below with reference to FIG. 1.
图1是目前终端设备向网络设备发送能力信息的示意性流程图，该能力信息可以为终端设备的无线接入能力信息，图1的步骤包括S11和S12，下面对这些步骤进行详细描述。需要说明的是，图1所述的步骤主要为终端设备和网络设备之间的信令流程，省略了网络设备和核心网之间的信令流程。FIG. 1 is a schematic flowchart of current capability information sent by a terminal device to a network device. The capability information may be wireless access capability information of the terminal device. The steps in FIG. 1 include S11 and S12. These steps are described in detail below. It should be noted that the steps described in FIG. 1 are mainly a signaling process between the terminal device and the network device, and the signaling process between the network device and the core network is omitted.
S11：网络设备向终端设备发送UE能力请求消息，则终端设备接收来自网络设备的UE能力请求消息，UE能力请求消息用于请求终端设备发送终端设备在某一(些)无线接入技术(radio access technology，RAT)中的无线接入能力信息。该UE能力请求消息可以指示一种或多种RAT(例如：演进的通用移动通信系统陆地无线接入E-UTRA技术，通用移动通信系统陆地无线接入UTRA技术，新无线(或新空口)技术NR，E-UTRA-NR中的一种或多种RAT)表示请求该种RAT下的终端设备的能力信息。S11: 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, and the UE capability request message is used to request the terminal device to send the terminal device in a certain radio access technology (radio) access capability information in RAT). The UE capability request message may indicate one or more RATs (for example: Evolved Universal Mobile Telecommunication System Terrestrial Radio Access E-UTRA Technology, Universal Mobile Telecommunications System Terrestrial Radio Access UTRA Technology, New Radio (or New Air Interface) Technology NR, one or more RATs in E-UTRA-NR) means requesting the capability information of the terminal equipment under the RAT.
例如UE能力请求消息例如为UE能力查询(UE capability enquiry)消息。For example, the UE capability request message is, for example, a UE capability query message.
对于一个处于连接态的终端设备，当核心网需要该终端设备的能力信息、且没有储存该终端设备的能力信息时，核心网可以触发网络设备发起UE能力请求过程，也就是发起图1所示的流程，来请求终端设备的能力信息。在网络设备发起请求后，终端设备会向网络设备发送终端设备的能力信息，网络设备会将终端设备的能力信息进一步发送给核心网，以便网络设备或核心网根据终端设备的能力来配置或调度终端设备。For a terminal device in the connected state, when the core network needs the capability information of the terminal device and does not store the capability information of the terminal device, the core network can trigger the network device to initiate a UE capability request process, that is, as shown in FIG. 1 Process to request the capability information of the terminal device. After the network device initiates the 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, so that the network device or the core network can configure or schedule the terminal device according to the terminal device's capability Terminal Equipment.
S12：终端设备向网络设备发送UE能力消息，则网络设备接收来自终端设备的该UE能力消息。S12: The terminal device sends a UE capability message to the network device, and the network device receives the UE capability message from the terminal device.
该UE能力消息携带终端设备的无线接入能力信息，例如，在网络设备发送的UE能力请求消息中包括了某一(些)RAT，则终端设备需要在UE能力消息中包括该一(些)RAT的能力信息，并且将UE能力消息中的RAT类型参数设置成该种RAT。例如：在UE能力请求消息中请求了E-UTRA-NR的UE能力信息，终端设备需要在UE能力消息中包括E-UTRA-NR的能力信息，并且将UE能力消息中的RAT类型参数设置成eutra-nr。The UE capability message carries the wireless access capability information of the terminal device. For example, if the UE capability request message sent by the network device includes a certain RAT (s), the terminal device needs to include the one (s) in the UE capability message. RAT capability information, and the RAT type parameter in the UE capability message is set to that kind of RAT. For example, the UE capability information of E-UTRA-NR is requested in the UE capability request message. The terminal device needs to include the capability information of E-UTRA-NR in the UE capability message, and set the RAT type parameter in the UE capability message to eutra-nr.
其中，UE能力消息例如通过UE能力信息(UE Capability Information)消息实现，可以是专门用于上报终端设备的能力信息的消息，在UE能力消息中可以包含该终端设备的至少一种无线接入技术的能力信息。终端设备的无线接入能力信息具体可以包括例如：PDCP参数、物理层参数、射频参数、测量参数等，这些能力参数具体对应的能力例如频带组合(band combination)、支持的载波聚合带宽级别(ca-BandwidthClass)、调制编码方式(Modulation and Coding Scheme)等能力信息。上述能力参数或能力信息为示例的能力参数或能力信息，具体完整的能力信息本发明在此不赘述。The UE capability message may be implemented by, for example, a UE Capability Information message, and may be a message specifically used to report capability information of a terminal device. The UE capability message may include at least one wireless access technology of the terminal device. Capability information. The wireless access capability information of the terminal device may specifically include, for example, PDCP parameters, physical layer parameters, radio frequency parameters, and measurement parameters. The capabilities corresponding to these capability parameters are, for example, band combination, supported carrier aggregation bandwidth level (ca -BandwidthClass), Modulation and Coding Scheme, and other capability information. The above capability parameter or capability information is an exemplary capability parameter or capability information, and specific and complete capability information is not described in detail in the present invention.
网络设备在接收UE能力消息之后，可以根据无线接入能力信息的具体的参数配置终端设备的PDCP配置、物理层配置、射频配置、测量配置等，保证终端设备的配置能够满足终端设备自身的能力，即，终端设备能够在网络设备的配置下正常工作。After receiving the UE capability 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 specific parameters of the wireless access capability information 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.
如图1所示的流程中所述，网络设备向终端设备发送UE能力请求消息，请求终端设备的一种或多种RAT的能力信息，终端设备需要在UE能力消息中上报终端设备的这一种或多种RAT的能力信息。也就是说，终端设备需要上报的所有的能力信息都必须承载在一条UE能力消息中发送给网络设备，而该UE能力消息是一条不可拆分的、完整的消息，该消息可以是RRC消息。其中，RRC消息是承载在PDCP SDU中发送。As described in the process shown in FIG. 1, the network device sends a UE capability request message to the terminal device, requesting the capability information of one or more RATs of the terminal device. The terminal device needs to report the terminal device's Capability information for one or more RATs. In other words, all the capability information that the terminal device needs to report must be carried in a UE capability message and sent to the network device, and the UE capability message is an indivisible and complete message, and the message may be an RRC message. Among them, the RRC message is sent in the PDCP and SDU.
而随着标准的演进，终端设备有多个版本，或者说终端设备所支持的技术有多个版本。例如，在Release 8之后又引入了Release 9、Release 10、Release 11、Release 12、Release 13、Release 14以及现在正在标准化的Release 15等版本，在每个Release里面可以包括不同的版本，如Release 9中包括v920、v940，以及v9a0、v9c0、v9d0、v9e0和v9h0等版本。可以理解为，一个Release是一个系列，一个系列中包括多个版本，例如Release9可以理解为系列9，在系列9中包括了v920、v940，以及v9a0、v9c0、v9d0、v9e0和v9h0等版本。其中每一个版本都会引入新的能力信息，也就是说，每个新版本的终端设备，除了具有老版本的终端设备所具有的能力信息外，还具有老版本的终端设备所不具有的新的能力信息。那么对于新版本的终端设备来说，在向网络设备发送终端设备的能力信息时，就需要发送老版本的终端设备所具有的能力信息，以及该新版本所引入的新的能力信息。那么显然，随着终端设备的版本逐渐演进，新版本的终端设备需要发送给网络设备的能力信息就会包括越来越多的内容，终端设备的能力信息的数据量也就会越来越大。With the evolution of standards, there are multiple versions of terminal equipment, or there are multiple versions of technologies supported by terminal equipment. For example, after Release 8, Release 9, 9, Release 10, Release 11, Release 12, 12, Release 13, Release 14, and Release 15, which are now being standardized, are introduced. Each Release can include different versions, such as Release 9 It includes v920, v940, and v9a0, v9c0, v9d0, v9e0, and v9h0 versions. It can be understood that a Release is a series, and a series includes multiple versions. For example, Release 9 can be understood as Series 9, which includes v920, v940, and v9a0, v9c0, v9d0, v9e0, and v9h0 versions. Each of these versions introduces new capability information, that is, each new version of the terminal device, in addition to having the capability information of the old version of the terminal device, also has new capabilities that the old version of the terminal device does not have. Capability information. Then, for the terminal device of the new version, when sending the capability information of the terminal device to the network device, it is necessary to send the capability information of the terminal device of the old version and the new capability information introduced by the new version. So obviously, as the version of the terminal device gradually evolves, the capability information that the new version of the terminal device needs to send to the network device will include more and more content, and the amount of data on the capability information of the terminal device will also increase. .
而在前文中介绍了，RRC消息是承载在PDCP SDU中发送的。在LTE系统中，一个PDCP SDU最大的容量为8188bytes，在NR系统中，一个PDCP SDU最大的容量为9000bytes。随着Release 15以及进一步的版本的逐渐演进，终端设备需要上报的能力信息会包括越来越多的内容，很有可能会超过PDCP SDU的最大容量。一旦终端设备需要上报的能力信息超过了PDCP SDU的最大容量，则无法将其放入PDCP SDU中，从而导致终端设备无法正确上报终端设备的能力信息。而网络设备无法获得终端设备的能力信息，也就无法正常调度终端设备，从而影响了网络设备的调度，也影响了终端设备的正常工作。As mentioned in the foregoing, the RRC message is transmitted in the PDCP and SDU. In the LTE system, the maximum capacity of a PDCP SDU is 8188 bytes, and in the NR system, the maximum capacity of a PDCP SDU is 9000 bytes. With the gradual evolution of Release 15 and further versions, the capability information that terminal devices need to report will include more and more content, which is likely to exceed the maximum capacity of PDCP and SDU. Once the capability information that the terminal device needs to report exceeds the maximum capacity of the PDCP SDU, it cannot be placed in the PDCP SDU, resulting in the terminal device not being able to correctly report the capability information of the terminal device. However, the network equipment cannot obtain the capability information of the terminal equipment, so the terminal equipment cannot be scheduled normally, which affects the scheduling of the network equipment and affects the normal work of the terminal equipment.
鉴于此，本申请实施例提供一种发送、接收能力信息的方法，在本申请实施例中，终端设备将终端设备的能力信息承载在至少两个能力消息中发送，从而尽量保证终端设备能够正常发送终端设备的能力信息，提高信息发送的成功率，尽量避免出现因终端设备的能力信息的数据量较大而导致的发送失败或无法发送的情况。In view of this, the embodiment of the present application provides a method for transmitting and receiving capability information. In the embodiment of the present application, the terminal device carries the capability information of the terminal device in at least two capability messages to transmit, so as to ensure that the terminal device can function normally. Send the capability information of the terminal device, improve the success rate of information transmission, and try to avoid the situation that the sending of the capability information of the terminal device fails or cannot be transmitted as much as possible.

Please refer to FIG. 4, which is a flowchart of the method. This method can be applied to the scenario shown in FIG. 2 or the scenario shown in FIG. 3. In the following description, the method provided in the embodiment of the present application is applied to the application scenario shown in FIG. 2 as an example.
S41、终端设备生成N个能力消息，所述N个能力消息中的每个能力消息分别包括所述终端设备的部分能力信息，N为大于或等于2的整数；S41. The terminal device generates N capability messages, each of the N capability messages includes part of the capability information of the terminal device, and N is an integer greater than or equal to 2;

The network device obtains partial capability information of the terminal device included in each of the N capability messages, and obtains the complete capability information of the terminal device according to the capability information included in the N capability messages.
在本实施例中，需要区分“能力消息”和“能力信息”这两个概念，能力信息用于指示终端设备的能力，能力消息包括能力信息，或者说能力消息用于承载能力信息，能力信息是通过能力消息发送给网络设备。In this embodiment, two concepts of “capability message” and “capacity information” need to be distinguished. The capability information is used to indicate the capability of the terminal device. The capability message includes capability information, or the capability message is used to carry capability information. It is sent to the network device through the capability message.
其中，在S41之前，网络设备可以向终端设备请求终端设备的能力信息，例如网络设备可以向终端设备发送UE能力请求消息，关于这部分内容可参考图1所示的流程中的相关介绍。Before S41, the network device can request the terminal device's capability information. For example, the network device can send a UE capability request message to the terminal device. For this content, refer to the related introduction in the process shown in FIG. 1.
例如，N个能力消息可以包括终端设备的完整能力信息，也就是说，终端设备是将终端设备的完整能力信息分割后放入了N个能力消息中发送。那么终端设备将N个能力消息发送给网络设备后，网络设备可以获取N个能力消息中的每个能力消息包括的能力信息，网络设备根据获取的所有的能力信息，就可以得到终端设备的完整能力信息。其中，终端设备的完整能力信息，例如为终端设备的全部的能力信息，或者是指终端设备能够完成某种功能的全部的能力信息，也就是说，终端设备的完整能力信息可以是终端设备的全部的能力信息，或者可以是终端设备的部分能力信息，如果终端设备的完整能力信息是终端设备的部分能力信息，那么终端设备的完整能力信息究竟是终端设备的哪部分能力信息，本实施例不作限制。For example, the N capability messages may include the complete capability information of the terminal device, that is, the terminal device divides the complete capability information of the terminal device into N capability messages and sends them. Then after the terminal device sends N capability messages to the network device, the network device can obtain the capability information included in each of the N capability messages, and the network device can obtain the completeness of the terminal device according to all the acquired capability information. Capability information. The complete capability information of the terminal device is, for example, the entire capability information of the terminal device, or the entire capability information of the terminal device capable of performing a certain function, that is, the complete capability information of the terminal device may be the terminal device's The entire capability information may be partial capability information of the terminal device. If the complete capability information of the terminal device is part of the capability information of the terminal device, then which part of the capability information of the terminal device is the complete capability information of the terminal device. This embodiment No restrictions.
为了更便于理解，下面通过几种实施方式，介绍N个能力消息所包括的能力信息的可能的实现形式。For easier understanding, the following describes the possible implementation forms of the capability information included in the N capability messages through several implementation manners.
作为第一种实现形式，在本申请实施例中，N个能力消息中的每个能力消息可以分别包括终端设备的至少一个版本的能力信息，也就是说，终端设备按照终端设备的版本将终端设备的能力信息分为不同的部分，分别放在不同的能力消息中发送，其中的每个能力消息都可以包括终端设备的至少一个版本的能力信息，当然为了减少重复传输，不同的能力消息包括的终端设备的能力信息对应的版本不同。例如，终端设备需要发送的能力信息包括v920的能力信息和v940的能力信息，那么终端设备可以将v920的能力信息放在一个能力消息中，以及将v940的能力信息放在另一个能力消息中，在这种情况下，每个能力消息包括了终端设备的一个版本的能力信息。或者例如，终端设备需要发送的能力信息包括v9a0的能力信息、v9c0的能力信息、v9d0的能力信息和v9e0的能力信息，那么终端设备可以将v9a0的能力信息、v9c0的能力信息、v9d0的能力信息和v9e0的能力信息分别放在4个能力消息中，其中的每个能力消息包括一个版本的能力信息，或者，终端设备也可以将其中的至少两个版本的能力信息放在一个能力消息中，而将剩余的版本的能力信息放在其他的能力消息中，例如终端设备将v9a0的能力信息和v9c0的能力信息放在 一个能力消息中，以及将v9d0的能力信息和v9e0的能力信息放在另一个能力消息中，在这种情况下，每个能力消息都包括多个版本的能力信息，或者终端设备将v9a0的能力信息、v9c0的能力信息和v9d0的能力信息放在一个能力消息中，以及将v9e0的能力信息放在另一个能力消息中，在这种情况下，有的能力消息包括多个版本的能力信息，有的能力消息包括一个版本的能力信息。As a first implementation form, in the embodiment of the present application, each capability message of the N capability messages may include capability information of at least one version of the terminal device, that is, the terminal device updates the terminal according to the version of the terminal device. The capability information of the device is divided into different parts and sent in different capability messages. Each capability message can include the capability information of at least one version of the terminal device. Of course, in order to reduce repeated transmission, different capability messages include The corresponding version of the capability information of the terminal device is different. For example, the capability information that the terminal device needs to send includes the capability information of v920 and the capability information of v940. Then the terminal device can put the capability information of v920 in one capability message and the capability information of v940 in another capability message. In this case, each capability message includes capability information for one version of the terminal device. Or, for example, the capability information that the terminal device needs to send includes the capability information of v9a0, the capability information of v9c0, the capability information of v9d0, and the capability information of v9e0. Then the terminal device can combine the capability information of v9a0, the capability information of v9c0, and the capability information of v9d0. And the capability information of v9e0 are respectively placed in 4 capability messages, each of which includes a version of capability information, or the terminal device may also include at least two versions of the capability information in one capability message, The remaining version of the capability information is placed in other capability messages. For example, the terminal device puts the capability information of v9a0 and v9c0 in one capability message, and the capability information of v9d0 and v9e0. In a capability message, in this case, each capability message includes multiple versions of capability information, or the terminal device puts the capability information of v9a0, the capability information of v9c0, and the capability information of v9d0 into one capability message, and Put the capability information of v9e0 in another capability message, in this case, some capability messages The capability information comprising a plurality of versions, some capabilities message includes a capability information version.
具体的，对于能力消息的数量，以及一个能力消息中究竟包括多少个版本的能力信息，本实施例不作限制。作为一种可选的方式，终端设备可以根据能力消息的容量来决定，在一个能力消息中可以放入尽量多的版本的能力信息，如果需要发送的能力信息的数据量大于一个能力消息的容量，那么就将大于一个能力消息的容量的能力信息放入另外的能力消息。当然，在一个能力消息中尽量放入一个版本对应的全部的能力信息，也就是说，一个版本对应的能力信息尽量不放入至少两个能力消息中，以便于网络设备能够更便于获得完整的能力信息。Specifically, the number of capability messages and how many versions of capability information are included in a capability message are not limited in this embodiment. As an optional method, the terminal device may decide according to the capacity of the capability message. A capability message may include as many versions of capability information as possible. If the amount of capability information to be sent is greater than the capacity of a capability message, Then, the capability information larger than the capacity of one capability message is put into another capability message. Of course, all capability information corresponding to a version is put into a capability message as much as possible, that is, the capability information corresponding to a version is not put into at least two capability messages as much as possible, so that the network device can more easily obtain the complete Capability information.
作为第二种实现形式，在本申请实施例中，N个能力消息中的每个能力消息可以分别包括终端设备的至少一种无线接入技术的能力信息，也就是说，终端设备按照终端设备支持的无线接入技术将终端设备的能力信息分为不同的部分，分别放在不同的能力消息中发送，其中的每个能力消息都可以包括终端设备的至少一种无线接入技术的能力信息，当然为了减少重复传输，不同的能力消息包括的终端设备的能力信息对应的无线接入技术不同。例如，终端设备需要发送的能力信息包括终端设备的E-UTRA的能力信息、终端设备的NR的能力信息和终端设备的通用移动通信系统(universal mobile telecommunication system，UTRA)的能力信息，那么终端设备可以将终端设备的E-UTRA的能力信息放在一个能力消息中，将终端设备的NR的能力信息放在一个能力消息中，以及将终端设备的UTRA的能力信息放在一个能力消息中，在这种情况下，每个能力消息包括了终端设备的一种无线接入技术的能力信息，或者，终端设备也可以将其中的至少两个无线接入技术的能力信息放在一个能力消息中，而将剩余的无线接入技术的能力信息放在其他的能力消息中，例如终端设备将终端设备的E-UTRA的能力信息和终端设备的UTRA的能力信息放在一个能力消息中，以及将终端设备的NR的能力信息放在另一个能力消息中，在这种情况下，有的能力消息包括终端设备的多种无线接入技术的能力信息，有的能力消息包括终端设备的一种无线接入技术的能力信息，或者，如果终端设备需要发送至少4种无线接入技术的能力信息，那么每个能力消息也可以都包括多种无线接入技术的能力信息。As a second implementation form, in the embodiment of the present application, each of the N capability messages may include capability information of at least one wireless access technology of the terminal device, that is, the terminal device Supported wireless access technologies divide the capability information of the terminal device into different parts and send them in different capability messages, each of which can include the capability information of at least one wireless access technology of the terminal device. Of course, in order to reduce repeated transmissions, different capability messages include different wireless access technologies corresponding to the capability information of the terminal device. For example, the capability information that the terminal device needs to send includes the E-UTRA capability information of the terminal device, the NR capability information of the terminal device, and the universal mobile communication system (UTRA) capability information of the terminal device, then the terminal device The capability information of the E-UTRA of the terminal device can be placed in a capability message, the capability information of the NR of the terminal device can be placed in a capability message, and the capability information of the UTRA of the terminal device can be placed in a capability message. In this case, each capability message includes capability information of one radio access technology of the terminal device, or the terminal device may also include capability information of at least two of the radio access technologies in one capability message. The remaining wireless access technology capability information is placed in other capability messages, for example, the terminal device puts the capability information of the terminal device's E-UTRA and the capability information of the terminal device's UTRA into one capability message, and the terminal device The NR capability information of the device is placed in another capability message. In this case, some The capability message includes capability information of multiple wireless access technologies of the terminal device, and some capability messages include capability information of one wireless access technology of the terminal device, or if the terminal device needs to send the capability of at least 4 wireless access technologies Information, then each capability message may also include capability information for multiple radio access technologies.
具体的，对于能力消息的数量，以及一个能力消息中究竟包括终端设备在多少个无线接入技术下的能力信息，本实施例不作限制。作为一种可选的方式，终端设备可以根据能力消息的容量来决定，在一个能力消息中可以放入终端设备的尽量多的无线接入技术的能力信息，如果需要发送的能力信息的数据量大于一个能力消息的容量，那么就将大于一个能力消息的容量的能力信息放入另外的能力消息。当然，在一个能力消息中尽量放入一种无线接入技术对应的全部的能力信息，也就是说，一种无线接入技术对应的能力信息尽量不放入至少两个能力消息中，以便于网络设备能够更便于获得完整的能力信息。Specifically, this embodiment does not limit the number of capability messages and whether the capability information of a terminal device includes the capability information of the radio access technology. As an optional method, the terminal device may decide according to the capacity of the capability message. As much capability information of the wireless access technology as the terminal device can be placed in a capability message. If the amount of capability information data needs to be sent, If the capacity is larger than one capacity message, then the capacity information larger than the capacity of one capacity message is put into another capacity message. Of course, all capability information corresponding to a radio access technology is put into a capability message as much as possible, that is, the capability information corresponding to a radio access technology is not put into at least two capability messages as much as possible in order to facilitate Network equipment makes it easier to obtain complete capability information.
作为第三种实现形式，在本申请实施例中，N个能力消息中的每个能力消息可以分别包括终端设备的部分能力信息，例如，终端设备先确定需要发送的全部的能力信息，并对全部的能力信息进行编码，在编码后，可以将编码后的能力信息进行分割，得到至少两个部分，并将其中的每个部分放入一个能力消息。终端设备在分割时，可以按照预设的长度来分割，预设的长度例如为能力消息的最大允许容量，或者也可以是其他的长度。这种形式可以认为是物理分割形式。在第三种实现形式下，网络设备可能无法对N个能力消息中的部分能力消息包括的能力信息进行单独译码，因此，网络设备在接收全部的N个能力消息后，可以按照能力消息的顺序，或者说按照能力消息包括的能力信息的顺序，将N个能力消息包括的所有的能力信息进行组合，再对组合后的能力消息进行译码，以得到终端设备的完整能力信息。As a third implementation form, in the embodiment of the present application, each of the N capability messages may include part of the capability information of the terminal device, for example, the terminal device first determines all the capability information that needs to be sent, and All the capability information is encoded. After the encoding, the encoded capability information can be divided to obtain at least two parts, and each part is put into a capability message. When the terminal device is divided, it may be divided according to a preset length. The preset length is, for example, the maximum allowable capacity of the capability message, or may be another length. This form can be considered as a form of physical division. In the third implementation form, the network device may not be able to decode the capability information included in some of the N capability messages separately. Therefore, after receiving all N capability messages, the network device may In order, or in the order of the capability information included in the capability message, all the capability information included in the N capability messages is combined, and then the combined capability message is decoded to obtain the complete capability information of the terminal device.
具体的，对于能力消息的数量，以及一个能力消息中包括的能力信息的内容等，本实施例不作限制， 对于一个能力消息中包括的能力信息的数据量，只要不大于一个能力消息的最大允许容量即可，其他的不作限制。Specifically, the number of capability messages and the content of the capability information included in a capability message are not limited in this embodiment. As for the data amount of the capability information included in a capability message, as long as it is not greater than the maximum allowable of a capability message. The capacity is sufficient, and the others are not limited.
当然，以上三种实现形式只是示例，终端设备还可以根据其他的划分依据来将终端设备的能力信息划分为多个部分，例如还可以根据业务类型来划分，将不同的业务类型对应的能力信息放在不同的能力消息中，例如将增强移动宽带(enhance mobile broadband，eMBB)类型对应的能力信息放在能力消息1中，将海量机器类通信(massive machine type of communication，mMTC)对应的能力信息放在能力消息2中，以及超级可靠低时延(ultra reliable&low latency communication，uRLLC)对应的能力信息放在能力消息3中。本实施例对于终端设备划分能力信息的依据不作限制。Of course, the above three implementation forms are just examples. The terminal device can also divide the capability information of the terminal device into multiple parts according to other division basis. For example, it can also be divided according to the service type, and the capability information corresponding to different service types can be divided. Placed in different capability messages, for example, capability information corresponding to enhanced mobile broadband (eMBB) type is placed in capability message 1, and capability information corresponding to massive machine type communication (mMTC) The capability information 2 is placed in the capability message 3 and the capability information corresponding to ultra reliable low latency (ulRLLC) is placed in the capability message 3. In this embodiment, the basis for dividing the capability information of the terminal device is not limited.
终端设备是通过N个能力消息来发送终端设备的完整能力信息，不同的能力消息包括的可以是终端设备的完整能力信息中的不同的部分。而网络设备接收N个能力消息后，就需要通过一定的方式，来根据N个能力消息包括的能力信息获得终端设备的完整能力信息。接下来就介绍终端设备如何指示能力消息之间的关系。具体的，终端设备指示能力消息之间的关系，可以有不同的指示方式，另外，能力消息的实现方式也可以有不同，因此下面结合能力消息的可能的实现方式来介绍终端设备指示能力消息的方式。需注意的是，能力消息的实现方式，和前文所述的能力消息中的能力信息的实现形式，二者是不同的概念，能力消息的实现方式与能力消息的结构有关，而能力消息中的能力信息的实现形式，是与能力消息中包括的能力信息的获得方式有关。The terminal equipment sends the complete capability information of the terminal equipment through N capability messages, and different capability messages may include different parts of the complete capability information of the terminal equipment. After receiving the N capability messages, the network device needs to obtain the complete capability information of the terminal device according to the capability information included in the N capability messages in a certain manner. The following describes how the terminal device indicates the relationship between the capability messages. Specifically, the relationship between the terminal device's indication capability message can have different indication modes. In addition, the implementation of the capability message can also be different. Therefore, the following describes the terminal equipment's indication capability message in combination with the possible implementation of the capability message. the way. It should be noted that the implementation method of the capability message and the implementation form of the capability information in the capability message described above are different concepts. The implementation method of the capability message is related to the structure of the capability message. The realization form of the capability information is related to the way of obtaining the capability information included in the capability message.
1、能力消息的第一种实现方式。1. The first implementation of capability messages.
如果能力消息通过UE capability information消息实现，那么，终端设备每演进一个版本，在新版本的终端设备发送的UE capability information消息中就会包括一种新的信息单元(information element，IE)，该新的版本所引入的新的能力信息就会包括在UE capability information消息包括的这种新的IE中，因此可以认为，终端设备的一个版本会对应一种IE，例如，不同版本对应的IE有不同的名称，终端设备的版本可以通过IE的名称与IE对应。并且每个版本对应的IE中都可以包括多个域(field)，不同的域包含了一系列的具体的能力参数。If the capability message is implemented by the UE capability information message, then each time a terminal device evolves a version, the UE capability information message sent by the new version of the terminal device includes a new information element (IE). The new information element (IE) The new capability information introduced in the new version will be included in the new IE included in the UE capability information message. Therefore, it can be considered that one version of the terminal device corresponds to one IE. For example, different versions correspond to different IEs. Name, the version of the terminal device can correspond to IE by the name of IE. And each version of the IE can include multiple fields, and different fields contain a series of specific capability parameters.
另外，如果能力消息通过UE capability information消息实现，那么，终端设备在支持的无线接入技术下的能力信息，也是通过IE来发送，可以这么理解，对于一种无线接入技术，终端设备可能有多个版本会支持，那么终端设备在该无线接入技术下的能力信息，也就包括了终端设备的多个版本在该无线接入技术下的能力信息。而终端设备的每个版本的能力信息都有相应的IE发送，因此也可以认为，终端设备所支持的无线接入技术也与IE对应。In addition, if the capability message is implemented by the UE capability information message, then the capability information of the terminal device under the supported wireless access technology is also sent through IE. It can be understood that for a wireless access technology, the terminal device may have Multiple versions will support, then the capability information of the terminal device under the radio access technology also includes the capability information of multiple versions of the terminal device under the radio access technology. The capability information of each version of the terminal device is sent by the corresponding IE, so it can also be considered that the wireless access technology supported by the terminal device also corresponds to the IE.
在能力消息的第一种实现方式的第一种情况下，如果认为N个能力消息之间是平等关系，那么，能力消息的第一种实现方式可以理解为，N个能力消息中的每个能力消息都包括了全部的IE，也就是说，N个能力消息中的每个能力消息所包括的IE都是相同的，但对于终端设备的一个版本或一种无线接入技术的能力信息来说，只包括在N个能力消息的其中一个能力消息所包括的IE中。In the first case of the first implementation of the capability message, if the N capability messages are considered to be an equal relationship, then the first implementation of the capability message can be understood as each of the N capability messages The capability message includes all IEs, that is, the IE included in each capability message of the N capability messages is the same, but for the capability information of a version of a terminal device or a wireless access technology, That is, it is only included in the IE included in one of the N capability messages.
例如，N个能力消息中的每个能力消息分别包括终端设备支持的至少一种无线接入技术的能力信息，对于终端设备支持的无线接入技术a来说，对应的能力信息包括在能力消息2中，则在能力消息2中会包括无线接入技术a对应的IE，无线接入技术a的能力信息就包括在该IE中。无线接入技术a的能力信息不包括在能力消息1中，但是在能力消息1中，也依然可以包括无线接入技术a对应的IE，只是在能力消息1的这个IE里不包括无线接入技术a的能力信息。For example, each of the N capability messages includes capability information of at least one radio access technology supported by the terminal device. For the radio access technology a supported by the terminal device, the corresponding capability information is included in the capability message. In 2, the capability message 2 includes the IE corresponding to the radio access technology a, and the capability information of the radio access technology a is included in the IE. The capability information of the radio access technology a is not included in the capability message 1, but in the capability message 1, the IE corresponding to the radio access technology a may still be included, but the radio access is not included in the IE of the capability message 1. Capability information for technology a.
在这种方式下，无论一个能力消息是否包括一个版本的能力信息或一种无线接入技术的能力信息，该能力消息都可以包括相应的IE，从而可以不改变能力消息的结构，更易于兼容，且易于使得网络设备解析能力消息。In this way, regardless of whether a capability message includes a version of capability information or capability information of a radio access technology, the capability message may include a corresponding IE, so that the capability message structure may not be changed, and it is easier to be compatible. , And it is easy for the network device to parse the capability message.
前文介绍了能力消息的第一种实现方式的第一种情况，而能力消息的第一种实现方式还包括第二种情况，在这种情况下，N个能力消息之间也可能不是平等关系，而是分级关系。例如，其中有一个能力消息会作为第一级能力消息，终端设备先向该第一级能力消息中放入能力信息，如果该能力消息的容量有限，或者为了减少每个能力消息的数据量，则终端设备也可以再将剩余的能力信息放入第二级能力消息。同理，如果第二级能力消息的容量有限，则终端设备也可以再将剩余的能力信息放入第三级能力消息，以此类推。那么在这种情况下，能力消息的第一种实现方式的第二种情况可以理解为，每一级能力消息包括部分的IE，在一个能力消息包括的IE中，可能有些IE包括能力信息，而有些IE不包括能力信息。其中，分割的IE会在前后两级能力消息中出现，前一级能力消息中只包括分割的IE，后一级能力消息中包括分割的IE和IE中的能力信息。The first case of the first implementation of the capability message is described above, and the first implementation of the capability message also includes the second case. In this case, the N capability messages may not be equal. , But a hierarchical relationship. For example, one of the capability messages is used as the first-level capability message. The terminal device first puts capability information into the first-level capability message. If the capacity of the capability message is limited, or in order to reduce the amount of data in each capability message, Then, the terminal device may also put the remaining capability information into the second-level capability message. Similarly, if the capacity of the second-level capability message is limited, the terminal device can also put the remaining capability information into the third-level capability message, and so on. Then in this case, the second case of the first implementation of the capability message can be understood as that each level of capability message includes part of the IE. Among the IEs included in a capability message, some IE may include capability information. Some IEs do not include capability information. Among them, the divided IE will appear in the two levels of capability messages. The previous level of capability messages includes only the divided IEs, and the latter level of capability messages includes the divided IEs and the capability information in the IEs.
例如，终端设备要发送版本1的能力信息、版本2的能力信息和版本3的能力信息，终端设备将版本1的能力信息放在第一级能力消息中发送，而将版本2的能力信息和版本3的能力信息放在第二级能力消息中发送，则第一级能力消息中就包括版本1对应的IE，该IE中包括版本1的能力信息，另外第一级能力消息还包括版本2对应的IE，但该IE中不包括版本2的能力信息以及通过版本2扩展出的其他版本的能力信息。而第二级能力消息中包括版本2对应的IE，该IE中包括版本2的能力信息，以及包括版本3对应的IE，该IE中包括版本3的能力信息，但第二级能力消息不包括版本1对应的IE，也不包括版本1的能力信息。其中，版本2对应的IE即为分割的IE，版本2对应的IE在第一级能力消息和第二级能力消息中都出现，第一级能力消息只包括版本2对应的IE，第二级能力消息包括版本2对应的IE、且该IE包括版本2的能力信息。For example, a terminal device needs to send version 1 capability information, version 2 capability information, and version 3 capability information. The terminal device sends version 1 capability information in a first-level capability message, and sends version 2 capability information and The capability information of version 3 is sent in the second-level capability message, and the first-level capability message includes the IE corresponding to version 1. The IE includes the capability information of version 1 and the first-level capability message also includes version 2. Corresponding IE, but this IE does not include capability information of version 2 and capability information of other versions extended by version 2. The second-level capability message includes the IE corresponding to version 2. The IE includes the capability information of version 2 and the IE corresponding to version 3. The IE includes the capability information of version 3. However, the second-level capability message does not include The IE corresponding to version 1 does not include the capability information of version 1. Among them, the IE corresponding to version 2 is a split IE. The IE corresponding to version 2 appears in both the first-level capability message and the second-level capability message. The first-level capability message includes only the IE corresponding to version 2 and the second-level capability. The capability message includes an IE corresponding to version 2, and the IE includes capability information of version 2.
如果采用这种方式，则可以减少能力消息中包括的IE的数量。If this method is adopted, the number of IEs included in the capability message can be reduced.
在这种方式下，如果网络设备获得了能力消息1，而能力消息1中与版本a对应的IE中又不包括版本a的能力信息，或者与无线接入技术a对应的IE中不包括版本a的能力信息，则网络设备需要获知版本a或无线接入技术a的能力信息在哪里。具体的，在能力消息的第一种实现方式下，包括但不限于三种终端设备指示能力消息的方式：In this manner, if the network device obtains the capability message 1, and the capability information 1 corresponding to the version a does not include the capability information of the version a, or the IE corresponding to the wireless access technology a does not include the version. a's capability information, the network device needs to know where the capability information of version a or radio access technology a is. Specifically, in the first implementation manner of the capability message, there are three types of ways for the terminal device to indicate the capability message:
1a、方式A1。1a, Mode A1.
在方式A1下，提供一种指示信息，例如称为第一指示信息，N个能力消息中的每个能力消息都可以包括至少一个第一指示信息，其中的每个第一指示信息指示终端设备的一个版本的能力信息，或者说，每个第一指示信息指示终端设备的一个版本的能力信息是在本能力消息中发送还是在其他能力消息中发送，本能力消息就是所述每个第一指示信息所在的能力消息。或者，其中的每个第一指示信息指示终端设备支持的一种无线接入技术的能力信息，或者说，每个第一指示信息指示终端设备支持的一种无线接入技术的能力信息是在本能力消息中发送还是在其他能力消息中发送，本能力消息就是所述每个第一指示信息所在的能力消息。In mode A1, an indication information is provided, for example, called first indication information. Each of the N capability messages may include at least one first indication information, and each of the first indication information indicates a terminal device. The capability information of one version of the, or each first indication information indicates whether the capability information of one version of the terminal device is sent in this capability message or in another capability message, and this capability message is the first Indicates the capability message where the information is located. Or, each of the first indication information indicates the capability information of a radio access technology supported by the terminal device, or each of the first indication information indicates that the capability information of a radio access technology supported by the terminal device is in Whether the capability message is sent in another capability message or not, the capability message is the capability message in which each first indication information is located.
例如，N个能力消息包括第一能力消息和第二能力消息，第一能力消息包括终端设备的部分能力信息，第二能力消息包括终端设备的部分能力信息。其中，第一能力消息的数量可以包括一个或多个，第二能力消息的数量也可以是一个或多个。另外，第一能力消息和第二能力消息的总数可以等于N，即，N个能力消息中就包括第一能力消息和第二能力消息，或者，第一能力消息和第二能力消息的总数也可以小于N，N个能力消息中除了包括第一能力消息和第二能力消息之外还包括其他的能力消息，具体的不作限制。下面主要通过第一能力消息和第二能力消息介绍本实施例提供的技术方案。For example, the N capability messages include a first capability message and a second capability message. The first capability message includes partial capability information of the terminal device, and the second capability message includes partial capability information of the terminal device. The number of the first capability messages may include one or more, and the number of the second capability messages may also be one or more. In addition, the total number of the first capability message and the second capability message may be equal to N, that is, the N capability messages include the first capability message and the second capability message, or the total number of the first capability message and the second capability message is also It can be smaller than N. The N capability messages include other capability messages in addition to the first capability message and the second capability message, which is not specifically limited. The following mainly introduces the technical solution provided by this embodiment through the first capability message and the second capability message.
借用第一能力消息和第二能力消息，对方式A1可以简单的理解为，例如N个能力消息中的每个能力消息分别包括终端设备的至少一个版本的能力信息，那么终端设备的一个版本的能力信息无论在第一能力消息还是第二能力消息中发送，第一能力消息和第二能力消息都会包括对应于该版本的第一指示信息，或者，例如N个能力消息中的每个能力消息分别包括终端设备支持的至少一种无线接入技术的能力信息， 那么终端设备的一种无线接入技术的能力信息无论在第一能力消息还是第二能力消息中发送，第一能力消息和第二能力消息都会包括对应于该无线接入技术的第一指示信息。Borrowing the first capability message and the second capability message, the method A1 can be simply understood as, for example, each capability message in the N capability messages includes at least one version of the capability information of the terminal device, and then a version of the terminal device Whether the capability information is sent in the first capability message or the second capability message, the first capability message and the second capability message will include the first indication information corresponding to the version, or, for example, each capability message of the N capability messages. Capability information of at least one radio access technology supported by the terminal device is included, respectively. Whether the capability information of a radio access technology of the terminal device is sent in the first capability message or the second capability message, the first capability message and the first capability message Both capability messages will include the first indication information corresponding to the radio access technology.
例如，第一能力消息包括第一指示信息，第一指示信息指示终端设备的第一部分能力信息在第二能力消息中发送，或者，第一指示信息指示终端设备的第一部分能力信息在第一能力消息中发送。这里的第一能力消息包括的第一指示信息，可以是第一能力消息所包括的至少一个第一指示信息中的一个。其中，第一部分能力信息可以是终端设备的一个版本的能力信息，在本文中，终端设备的一个版本的能力信息，例如是终端设备的一个版本的全部的能力信息，或者是终端设备的一个版本的部分能力信息。或者，第一部分能力信息也可以是终端设备支持的一种无线接入技术的能力信息，在本文中，终端设备支持的一种无线接入技术的能力信息，例如是终端设备支持的一种无线接入技术的全部的能力信息，或者是终端设备支持的一种无线接入技术的部分能力信息。For example, the first capability message includes first indication information, the first indication information indicates that the first part of the capability information of the terminal device is sent in the second capability message, or the first indication information indicates that the first part of the capability information of the terminal device is in the first capability. Sent in a message. The first indication information included in the first capability message herein may be one of at least one first indication information included in the first capability message. The first part of the capability information may be the capability information of one version of the terminal device. In this article, the capability information of one version of the terminal device is, for example, the entire capability information of one version of the terminal device, or it is one version of the terminal device. Partial capability information. Alternatively, the first piece of capability information may also be capability information of a wireless access technology supported by the terminal device. In this article, the capability information of a wireless access technology supported by the terminal device is, for example, a wireless access technology supported by the terminal device. Full capability information of the access technology, or partial capability information of a wireless access technology supported by the terminal device.
在方式A1中，第一指示信息均包括在能力消息的相应的IE中。例如，将在第一能力消息中包括的与第一部分能力信息所属的无线接入技术对应的IE称为第一IE，将在第二能力消息中包括的与第一部分能力信息所属的无线接入技术对应的IE称为第二IE，那么第一能力消息如果包括对应于第一部分能力信息的第一指示信息，该第一指示信息就位于第一IE中，第二能力消息如果包括对应于第一部分能力信息的第一指示信息，该第一指示信息就位于第二IE中。方式A1，可以是通过IE包括的第一指示信息来指示对应的能力信息是在本能力消息中发送，还是在其他能力消息中发送。需要注意的是，在本文中提及的第一IE和第二IE实际上是相同的IE，具有相同的名称和其他属性等，是将同一IE放在不同的能力消息中，为了区分不同的能力消息，就分别命名为第一IE和第二IE，后文也是类似的，不多赘述。In manner A1, the first indication information is included in the corresponding IE of the capability message. For example, an IE corresponding to a radio access technology to which the first part of the capability information is included in the first capability message is referred to as a first IE, and a radio access to which the first part of the capability information is included in the second capability message is The IE corresponding to the technology is called the second IE. If the first capability message includes the first indication information corresponding to the first part of the capability information, the first indication information is located in the first IE. The first indication information of part of the capability information is located in the second IE. In manner A1, the first indication information included in the IE may be used to indicate whether the corresponding capability information is sent in this capability message or in another capability message. It should be noted that the first IE and the second IE mentioned in this article are actually the same IE, have the same name and other attributes, etc. The same IE is placed in different capability messages, in order to distinguish different The capability messages are named the first IE and the second IE, respectively. The following is similar, so I won't go into details.
具体的，第一能力消息和第二能力消息都包括第一指示信息，第一指示信息指示第一部分能力信息在本能力消息中发送或在其他能力消息中发送，而第一部分能力信息只包括在其中一个能力消息里，因此，第一指示信息在第一能力消息和第二能力消息中需要指示不同的内容。在本实施例中，第一指示信息可以通过取值的不同来指示不同的内容。Specifically, the first capability message and the second capability message both include first indication information, and the first indication information indicates that the first part of the capability information is sent in this capability message or in other capability messages, and the first part of the capability information is only included in In one of the capability messages, the first indication information needs to indicate different content in the first capability message and the second capability message. In this embodiment, the first indication information may indicate different contents by different values.
例如，第一指示信息可以包括两种取值，分别为第一值和第二值，如果第一指示信息的取值为第一值，则指示第一部分能力信息在其他能力消息中发送，如果第一指示信息的取值为第二值，则指示第一部分能力信息在本能力消息中发送。For example, the first indication information may include two types of values, namely the first value and the second value. If the value of the first indication information is the first value, it indicates that the first part of the capability information is sent in other capability messages. If the value of the first indication information is the second value, it indicates that the first part of the capability information is sent in the capability message.
网络设备在读取IE时，可以先读取IE中包括的第一指示信息，如果确定第一指示信息的取值为第一值，网络设备就可以确定该IE对应的能力信息是在其他能力消息中发送，则网络设备不必再进一步读取该IE，节省网络设备的操作步骤，而如果确定第一指示信息的取值为第二值，网络设备就可以确定该IE对应的能力信息是在本能力消息中发送，则网络设备可以进一步读取该IE中包括的能力信息，从而避免了能力消息的遗漏。When a network device reads an IE, it may first read the first indication information included in the IE. If it is determined that the value of the first indication information is the first value, the network device may determine that the capability information corresponding to the IE is in other capabilities. When sent in the message, the network device does not need to further read the IE, saving the operation steps of the network device, and if it is determined that the value of the first instruction information is the second value, the network device can determine that the capability information corresponding to the IE is in When sent in this capability message, the network device can further read the capability information included in the IE, thereby avoiding the omission of the capability message.
前面介绍了第一指示信息可通过不同的取值来指示不同的内容，那么下面就介绍第一指示信息的可能的实现方式。It was introduced earlier that the first indication information can indicate different contents through different values, so the following describes possible implementations of the first indication information.
例如，第一指示信息可以通过布尔(BOOLEAN)类型来指示，布尔类型的取值可以是真(true)或者假(false)，这两种取值可以分别表示不同的含义。例如，当一个第一指示信息的取值为true时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在本能力消息中发送，而当一个第一指示信息的取值为false时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在其他能力消息中发送，或者，当一个第一指示信息的取值为true时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在其他能力消息中发送，而当一个第一指示信息的取值为false时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在本能力消息中发送。For example, the first indication information may be indicated by a Boolean (BOOLEAN) type, and a value of the Boolean type may be true or false, and the two values may represent different meanings, respectively. For example, when a value of the first indication information is true, it indicates that the capability information corresponding to the IE where the first indication information is located (or, in other words, the capability information corresponding to the first indication information) is sent in the capability message, When a value of the first indication information is false, it indicates that the capability information corresponding to the IE where the first indication information is located (or the capability information corresponding to the first indication information) is sent in other capability messages, or When the value of a first indication information is true, it indicates that the capability information corresponding to the IE where the first indication information is located (or the capability information corresponding to the first indication information) is sent in other capability messages, and When a value of the first indication information is false, it indicates that the capability information corresponding to the IE where the first indication information is located (or the capability information corresponding to the first indication information) is sent in the capability message.
或者，第一指示信息也可以通过枚举(ENUMBERATED)类型来指示，ENUMBERATED有多种可能的取值，每个取值有不同的含义。例如，ENUMBERATED的取值可以包括{true，false}、{0,1}或{current,next}中的一个，当第一指示信息的取值为这三个集合中任意一个集合的前一个值时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在本能力消息中发送，当第一指示信息的取值为这三个集合中任意一个集合的后一个值时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在其他能力消息中发送，或者，当第一指示信息的取值为这三个集合中任意一个集合的前一个值时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在其他能力消息中发送，当第一指示信息的取值为这三个集合中任意一个集合的后一个值时，表示该第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在本能力消息中发送。例如第一指示信息的取值包括{0,1}，那么，如果第一指示信息的取值为0，表示第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在本能力消息中发送，如果第一指示信息的取值为1，表示第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在其他能力消息中发送，或者，如果第一指示信息的取值为0，表示第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在其他能力消息中发送，如果第一指示信息的取值为1，表示第一指示信息所在的IE对应的能力信息(或者说，是该第一指示信息对应的能力信息)在本能力消息中发送。Alternatively, the first indication information may also be indicated by an enumeration (ENUMBERATED) type. ENUMBERATED has multiple possible values, and each value has a different meaning. For example, the value of ENUMBERATED may include one of {true, false}, {0,1}, or {current, next}. When the value of the first indication information is the previous value of any one of the three sets, , The capability information corresponding to the IE where the first indication information is located (or the capability information corresponding to the first indication information) is sent in this capability message. When the value of the first indication information is the three sets, When the latter value of any one of the set indicates that the capability information corresponding to the IE where the first indication information is located (or the capability information corresponding to the first indication information) is sent in another capability message, or when the first When the value of the indication information is the previous value of any one of the three sets, it indicates that the capability information corresponding to the IE where the first indication information is located (or, in other words, the capability information corresponding to the first indication information) It is sent in the capability message. When the value of the first indication information is the latter value of any one of the three sets, it indicates the capability information corresponding to the IE where the first indication information is located (or, it is the first Information corresponding to the capability information shown) transmits this capability message. For example, the value of the first instruction information includes {0,1}. If the value of the first instruction information is 0, it indicates that the capability information corresponding to the IE where the first instruction information is located (or the first instruction information). The corresponding capability information is sent in this capability message. If the value of the first indication information is 1, it indicates the capability information corresponding to the IE where the first indication information is located (or the capability information corresponding to the first indication information). Sent in other capability messages, or if the value of the first indication information is 0, it indicates that the capability information (or capability information corresponding to the first indication information) corresponding to the IE where the first indication information is located is in another capability. It is sent in the message. If the value of the first indication information is 1, it indicates that the capability information corresponding to the IE where the first indication information is located (or in other words, the capability information corresponding to the first indication information) is transmitted in the capability message.
当然，如上的第一指示信息的几种实现方式只是示例，本实施例对于第一指示信息的具体实现方式及指示方式等不做限定，只要能指示需要的意思即可。Of course, the several implementation manners of the first indication information as described above are merely examples, and the specific implementation manner and indication manner of the first indication information are not limited in this embodiment, as long as the required meaning can be indicated.
如上介绍了能力消息的第一种实现方式下的方式A1，在方式A1下，无论能力消息是否包括相应的能力信息，都会包括该能力信息对应的第一指示信息。这种指示方式较为明确，对于网络设备来说，无论先获取了哪个能力消息，都能较为明确地获知相应的能力消息是在该能力消息中还是在其他能力消息中。下面介绍能力消息的第一种实现方式下的方式A2。The manner A1 in the first implementation manner of the capability message is introduced as above. In the manner A1, regardless of whether the capability message includes corresponding capability information, the first indication information corresponding to the capability information is included. This indication is relatively clear. For a network device, no matter which capability message is acquired first, it can be more clearly known whether the corresponding capability message is in the capability message or other capability messages. The following describes the method A2 in the first implementation of the capability message.
1b、方式A2。1b, Mode A2.
在方式A2下，还是提供一种指示信息，例如依然称为第一指示信息，需注意的是，方式A2下的第一指示信息与方式A1下的第一指示信息可以是不同的指示信息，这里的不同，是指二者的指示方式不同。但方式A2下的第一指示信息与方式A1下的第一指示信息的实现方式可能是相同的，例如都可以通过枚举类型实现，或者方式A2下的第一指示信息与方式A1下的第一指示信息的实现方式也可以不同，例如方式A2下的第一指示信息通过枚举类型实现，而方式A1下的第一指示信息通过布尔类型实现。In mode A2, a kind of instruction information is still provided, for example, it is still called first instruction information. It should be noted that the first instruction information in mode A2 and the first instruction information in mode A1 may be different instruction information. The difference here means that the two instructions are different. However, the implementation manner of the first instruction information in mode A2 and the first instruction information in mode A1 may be the same. For example, both can be implemented by enumeration types, or the first instruction information in mode A2 and the first instruction information in mode A1. An implementation manner of the indication information may also be different. For example, the first indication information in the manner A2 is implemented by an enumeration type, and the first indication information in the manner A1 is implemented by a Boolean type.
在方式A1下，无论能力消息是否包括相应的能力信息，都会包括该能力信息对应的第一指示信息，而方式A2则不然，在方式A2下，如果能力消息包括相应的能力信息，则该能力消息可以包括与该能力信息对应的第一指示信息，如果能力消息不包括相应的能力信息，则该能力消息也就可以不包括与该能力信息对应的第一指示信息，或者，如果能力消息包括相应的能力信息，则该能力消息可以不包括与该能力信息对应的第一指示信息，如果能力消息不包括相应的能力信息，则该能力消息可以包括与该能力信息对应的第一指示信息，也就是说，对于一个能力信息来说，其对应的第一指示信息只存在于一个能力消息中，而不会存在于每个能力消息中。通过这种方式，可以减少能力消息所包括的信息的数量，也就是能够减少传输的数据量。In mode A1, regardless of whether the capability message includes the corresponding capability information, the first indication information corresponding to the capability information is included, but not in mode A2. In mode A2, if the capability message includes the corresponding capability information, the capability The message may include first indication information corresponding to the capability information. If the capability message does not include corresponding capability information, the capability message may not include the first indication information corresponding to the capability information, or if the capability message includes Corresponding capability information, the capability message may not include the first indication information corresponding to the capability information, and if the capability message does not include the corresponding capability information, the capability message may include the first indication information corresponding to the capability information, That is, for a piece of capability information, the corresponding first indication information exists only in one capability message, and not in each capability message. In this way, the amount of information included in the capability message can be reduced, that is, the amount of data transmitted can be reduced.
继续通过第一能力消息和第二能力消息介绍本实施例提供的技术方案。其中，对于第一部分能力信息的介绍可参考如前的方式A1。Continue to introduce the technical solution provided by this embodiment through the first capability message and the second capability message. For the introduction of the first part of the capability information, please refer to the previous manner A1.
在方式A2中，能力消息中可能包括第一指示信息，也可能不包括第一指示信息，如果能力消息包括第一指示信息，则第一指示信息就位于能力消息所包括的相应的IE中。方式A2，可以是根据能力消 息中的IE中是否包括第一指示信息，来指示对应的能力信息是在本能力消息中发送还是在其他能力消息中发送。例如，第一能力消息中包括第一IE，第一IE包括第一指示信息，则指示对应的第一部分能力信息在本能力消息中发送，反之，第一IE不包括第一指示信息，则指示对应的第一部分能力信息在其他能力消息中发送。或者，第一能力消息中包括第一IE，第一IE中不包括第一指示信息，则指示对应的第一部分能力信息在本能力消息中发送，反之，第一IE不包括第一指示信息，则指示对应的第一部分能力信息在其他能力消息中发送。In the method A2, the capability message may include the first indication information or may not include the first indication information. If the capability message includes the first indication information, the first indication information is located in a corresponding IE included in the capability message. Method A2 may be to indicate whether the corresponding capability information is sent in the capability message or in another capability message according to whether the IE in the capability message includes the first indication information. For example, if the first capability message includes the first IE, and the first IE includes the first indication information, the corresponding first part of the capability information is instructed to be sent in this capability message; otherwise, the first IE does not include the first indication information, and the indication The corresponding first part of the capability information is sent in other capability messages. Or, if the first capability message includes the first IE, and the first IE does not include the first indication information, the corresponding first part of the capability information is instructed to be sent in this capability message. Otherwise, the first IE does not include the first indication information. Then it indicates that the corresponding first part of the capability information is sent in other capability messages.
在本实施例中，可以不必关注第一指示信息的取值，只要第一指示信息存在，就可以指示第一部分能力信息在本能力消息中发送或在其他能力消息中发送，而如果第一指示信息不存在，又可以指示相反的内容。In this embodiment, it is not necessary to pay attention to the value of the first indication information. As long as the first indication information exists, the first piece of capability information may be instructed to be sent in this capability message or in other capability messages. Information does not exist and can indicate the opposite.
或者，虽然是通过包括第一指示信息或不包括第一指示信息来指示不同的内容，但在本实施例中，也可以设置第一指示信息的取值，例如将第一指示信息的取值设置为第三值。通过关注第一指示信息的取值，可以尽量避免出错，例如可尽量避免将其他的信息误认为是第一指示信息。Alternatively, although different content is indicated by including or not including the first instruction information, in this embodiment, the value of the first instruction information may also be set, such as the value of the first instruction information. Set to the third value. By paying attention to the value of the first indication information, errors can be avoided as much as possible, for example, other information can be avoided from being mistaken for the first indication information.
作为一种实施方式，第一指示信息可以通过枚举类型实现。例如可以将第三值设置为true(例如，形式为ENUMERATED{ture})，或者设置为支持(supported)(例如，形式为ENUMERATED{supported})，具体的不作限制。对于第一指示信息取值为第三值的指示方式，可参考前文的介绍。当然，第一指示信息也可以通过其他方式实现，例如也可以通过布尔类型实现等，具体的也不作限制。As an implementation manner, the first indication information may be implemented by using an enumeration type. For example, the third value may be set to true (for example, the form is ENUMERATED {ture}) or set to supported (for example, the form is ENUMERATED {supported}), and the specific value is not limited. For the indication method in which the first instruction information has a third value, reference may be made to the foregoing description. Of course, the first indication information may also be implemented by other methods, for example, it may also be implemented by a Boolean type, and the like is not specifically limited.
网络设备在读取IE时，可以先读取IE中包括的第一指示信息，如果该IE包括第一指示信息，则根据第一指示信息(或者根据取值为第三值的第一指示信息)可以确定该IE对应的能力信息是在其他能力消息中发送或在本能力消息中发送，同样的，如果该IE不包括第一指示信息，网络设备也可以确定该IE对应的能力信息是在其他能力消息中发送或在本能力消息中发送。如果确定该IE对应的能力信息在其他能力消息中发送，则网络设备不必再进一步读取该IE，节省网络设备的操作步骤，而如果确定该IE对应的能力信息是在本能力消息中发送，则网络设备可以进一步读取该IE中包括的能力信息，从而避免了能力消息的遗漏。When the network device reads the IE, the first instruction information included in the IE may be read first. If the IE includes the first instruction information, the first instruction information (or the first instruction information having a third value) is used. ) It can be determined that the capability information corresponding to the IE is sent in other capability messages or in this capability message. Similarly, if the IE does not include the first indication information, the network device can also determine that the capability information corresponding to the IE is in Sent in other capability messages or in this capability message. If it is determined that the capability information corresponding to the IE is sent in another capability message, the network device does not need to further read the IE to save the operation steps of the network device, and if it is determined that the capability information corresponding to the IE is sent in the capability message, Then the network device can further read the capability information included in the IE, thereby avoiding omission of capability messages.
而如果该IE不包括第一指示信息，则网络设备无需读取第一指示信息，可以读取该IE的其他信息，如果该IE包括能力信息，则网络设备可读取该IE包括的能力信息，如果该IE不包括能力信息，则网络设备可以无需读取该IE，或者可以读取该IE包括的其他信息等。If the IE does not include the first indication information, the network device does not need to read the first indication information, and can read other information of the IE. If the IE includes capability information, the network device can read the capability information included in the IE. If the IE does not include capability information, the network device may not need to read the IE, or may read other information included in the IE.
1c、方式A3。1c, Mode A3.
在方式A3下，提供两种指示信息，分别称为第二指示信息和第三指示信息，其中，第二指示信息可以用于指示终端设备的第一部分能力信息在其他能力消息中发送，若存在第二指示信息，即存在终端设备的第一部分能力信息在其他能力消息中发送，那么，发送终端设备的第一部分能力信息的其他能力消息中还包括第三指示信息。继续以第一能力消息和第二能力消息为例来介绍本实施例的方案。In mode A3, two types of indication information are provided, which are called second indication information and third indication information, wherein the second indication information may be used to instruct the first part of the capability information of the terminal device to be sent in other capability messages. The second indication information, that is, the first part of the capability information of the existing terminal device is sent in another capability message, and then the other capability message that sends the first part of the capability information of the terminal device further includes the third indication information. The first capability message and the second capability message are used as examples to introduce the solution of this embodiment.
那么，在N个能力消息的第一种实现方式的第一种情况下，则，如果第一能力消息不包括第一部分能力信息，那么第一能力消息就包括第二指示信息，就可以指示终端设备的第一部分能力信息在其他能力消息中发送，或者具体的，是指示终端设备的第一部分能力信息在第二能力消息中发送，而第二能力消息就包括第一部分能力信息，还包括第三指示信息，。需要说明的是，如果第一能力消息包括第一部分能力信息，即第一部分能力信息在本能力消息中发送，那么第一能力消息就不包括第二指示信息，因此，可以通过是否包括第二指示信息来指示第一部分能力信息是在其他能力消息中发送还是在本能力消息中发送。而，在N个能力消息的第一种实现方式的第二种情况下，则，如果上一级能力消息不包括第一部分能力信息，处理方式与上述第一能力消息不包括第一部分能力信息的方式相同，而如果上一级能力消息包括第一部分能力信息，那么该上一级能力消息和对应的下一级能力消息都可以不再包括对应于 第一部分能力信息的指示信息，也就是，不存在第二指示信息和第三指示信息。Then, in the first case of the first implementation manner of the N capability messages, if the first capability message does not include the first part of the capability information, the first capability message includes the second indication information, and the terminal may be instructed The first part of the capability information of the device is sent in other capability messages, or specifically, the first part of the capability information that instructs the terminal device to be sent in the second capability message, and the second capability message includes the first part of capability information and also the third Instructions, It should be noted that if the first capability message includes the first part of the capability information, that is, the first part of the capability information is sent in this capability message, the first capability message does not include the second indication information. Therefore, whether the second indication is included Information to indicate whether the first piece of capability information is sent in other capability messages or in this capability message. However, in the second case of the first implementation of the N capability messages, if the upper-level capability message does not include the first part of the capability information, the processing method is the same as that of the first capability message that does not include the first part of the capability information. The method is the same, and if the upper-level capability message includes the first part of the capability information, both the upper-level capability message and the corresponding next-level capability message may no longer include the indication information corresponding to the first-part capability information, that is, not There is second instruction information and third instruction information.
在方式A3下，只要第二指示信息和第三指示信息存在，则第二指示信息和第三指示信息就是一一对应的，一对第二指示信息和第三指示信息对应一个能力信息。其中，第二指示信息和第三指示信息的取值可以相同，此时可以认为第二指示信息和第三指示信息实际上是同一个指示信息，具有相同的名称和其他属性等，或者二者的取值也可以不同，但是可以相关，例如第二指示信息和第三指示信息的一种相关方式为，将第二指示信息和第三指示信息合并后可以得到一个完整的信息，或者第二指示信息和第三指示信息都指示同一对象，例如该对象为一种IE的名称，等等。In mode A3, as long as the second instruction information and the third instruction information exist, the second instruction information and the third instruction information correspond one-to-one, and the pair of the second instruction information and the third instruction information correspond to one capability information. The values of the second instruction information and the third instruction information may be the same. At this time, it can be considered that the second instruction information and the third instruction information are actually the same instruction information, have the same name and other attributes, or both. The value of can also be different, but can be related. For example, a related manner of the second indication information and the third indication information is to obtain a complete information after combining the second indication information and the third indication information, or the second indication information and the third indication information. Both the indication information and the third indication information indicate the same object, for example, the object is a name of an IE, and so on.
例如，第一部分能力信息在第二能力消息中发送，则第一能力消息包括对应于第一部分能力信息的第一IE，第一IE中不包括第一部分能力信息、但可以包括第二指示信息，指示第一部分能力信息在其他能力消息中发送，第二能力消息中包括对应于第一部分能力信息的第二IE，第二IE中包括第一部分能力信息、还可以包括第三指示信息。For example, if the first part of the capability information is sent in the second capability message, the first capability message includes the first IE corresponding to the first part of the capability information. The first IE does not include the first part of the capability information but may include the second indication information. The first part of the capability information is sent in another capability message. The second capability message includes a second IE corresponding to the first part of the capability information. The second IE includes the first part of the capability information and may also include the third indication information.
网络设备在读取IE时，可以先读取IE中包括的指示信息，如果该IE包括指示信息，且读取的是第二指示信息，网络设备就可以确定该IE对应的能力信息是在其他能力消息中发送，则网络设备不必再进一步读取该IE，节省网络设备的操作步骤，而如果读取的是第三指示信息，网络设备就可以确定该IE对应的能力信息是在本能力消息中发送，则网络设备可以进一步读取该IE中包括的能力信息，从而避免了能力消息的遗漏。当然，如果读取的IE不包括指示信息，则网络设备可以直接读取该IE包括的内容。When a network device reads an IE, it can first read the instruction information included in the IE. If the IE includes the instruction information and reads the second instruction information, the network device can determine that the capability information corresponding to the IE is in another If the capability message is sent, the network device does not need to further read the IE, which saves the operation steps of the network device. If the third instruction information is read, the network device can determine that the capability information corresponding to the IE is in the capability message. Sending, the network device can further read the capability information included in the IE, thereby avoiding the omission of capability messages. Of course, if the read IE does not include the indication information, the network device can directly read the content included in the IE.
在能力消息的第一种实现方式下的方式A1和方式A2，可以理解为，是通过IE来索引能力消息，例如，第一部分能力信息在第二能力消息中发送而不在第一能力消息中发送，但在这两个能力消息中都会包括第一部分能力信息对应的IE，则网络设备通过该IE就可以将第一能力消息和第二能力消息索引在一起，从而可以得到第一部分能力信息。例如网络设备可以通过IE的名称来索引，或者也可以通过IE的其他属性来索引。In the first implementation manner of the capability message, the manner A1 and the manner A2 can be understood as indexing the capability message through IE. For example, the first part of the capability information is sent in the second capability message but not in the first capability message. However, in both of the capability messages, the IE corresponding to the first part of the capability information is included, and then the network device can index the first capability message and the second capability message together through the IE, thereby obtaining the first part of the capability information. For example, a network device may be indexed by the name of the IE, or may be indexed by other attributes of the IE.
而在能力消息的第一种实现方式下的方式A3，可以理解为，可以通过IE和/或指示信息来索引能力消息，这里的指示信息包括第二指示信息和第三指示信息。例如，第一部分能力信息在第二能力消息中发送而不在第一能力消息中发送，但在这两个能力消息中都包括第一部分能力信息对应的IE，则网络设备通过该IE可以将第一能力消息和第二能力消息索引在一起，另外，网络设备还可以读取第一能力消息中的第二指示信息(或第三指示信息)以及第二能力消息中的第三指示信息(或第二指示信息)，如果第一能力消息中的第二指示信息(或第三指示信息)与第二能力消息中的第三指示信息(或第二指示信息)相同或相关，则网络设备确定第一能力消息和第二能力消息索引成功，从而通过第一能力消息和第二能力消息获得第一部分能力信息。如果网络设备通过IE和指示信息来索引能力消息，则双重索引方式可以使得网络设备最终获得的能力信息更为准确。In the first implementation manner of the capability message, way A3 can be understood as that the capability message can be indexed through IE and / or instruction information, and the instruction information here includes the second instruction information and the third instruction information. For example, if the first part of the capability information is sent in the second capability message but not in the first capability message, but both of the capability messages include the IE corresponding to the first part of the capability information, the network device can send the first capability information through the IE. The capability message and the second capability message are indexed together. In addition, the network device may also read the second indication information (or the third indication information) in the first capability message and the third indication information (or the first indication in the second capability message). Second indication information), if the second indication information (or the third indication information) in the first capability message is the same as or related to the third indication information (or the second indication information) in the second capability message, the network device determines the first The indexing of the first capability message and the second capability message succeeds, thereby obtaining the first part of the capability information through the first capability message and the second capability message. If the network device indexes the capability message through the IE and the indication information, the double indexing method can make the capability information finally obtained by the network device more accurate.
2、能力消息的第二种实现方式。2. A second implementation of the capability message.
继续以能力消息通过UE capability information消息实现为例，能力消息的第二种实现方式可以理解为，对于N个能力消息中的每个能力消息来说，如果包括了相应的能力信息，那么就可以包括该能力信息对应的IE，例如该能力信息就可以位于该能力信息对应的IE中，而如果一个能力消息不包括相应的能力信息，那么该能力消息就可以不包括该能力信息对应的IE。通过这种方式，可以尽量减少能力消息所包括的内容，减少传输的数据量。当然，如果采用已有的消息来实现能力消息，例如采用使用UE capability information消息实现，那么这种方式需要相应改变UE capability information消息的结构，例如可能会从中去除某些IE。Continue taking the implementation of the capability message through the UE capability information message as an example. The second implementation of the capability message can be understood as that for each capability message in the N capability messages, if the corresponding capability information is included, then Include the IE corresponding to the capability information. For example, the capability information may be located in the IE corresponding to the capability information. If a capability message does not include the corresponding capability information, the capability message may not include the IE corresponding to the capability information. In this way, the content included in the capability message can be minimized and the amount of data transmitted can be reduced. Of course, if the existing message is used to implement the capability message, for example, the UE capability information message is used, then this method needs to change the structure of the UE capability information message, for example, some IEs may be removed from it.
例如，N个能力消息中的每个能力消息分别包括终端设备的至少一个版本的能力信息，对于终端设备的版本a来说，对应的能力信息包括在能力消息2中，则在能力消息2中会包括版本a对应的IE，版本a的 能力信息就包括在该IE中。版本a的能力信息不包括在能力消息1中，则在能力消息1中，可以不包括版本a对应的IE。For example, each of the N capability messages includes capability information of at least one version of the terminal device. For version a of the terminal device, the corresponding capability information is included in the capability message 2. The IE corresponding to version a will be included, and the capability information of version a is included in the IE. The capability information of version a is not included in capability message 1. In capability message 1, the IE corresponding to version a may not be included.
或者，N个能力消息中的每个能力消息分别包括终端设备支持的至少一个无线接入技术的能力信息，对于终端设备支持的无线接入技术a来说，对应的能力信息包括在能力消息2中，则在能力消息2中会包括无线接入技术a对应的IE，无线接入技术a的能力信息就包括在该IE中。无线接入技术a的能力信息不包括在能力消息1中，则在能力消息1中，可以不包括无线接入技术a对应的IE。Alternatively, each of the N capability messages includes capability information of at least one radio access technology supported by the terminal device. For the radio access technology a supported by the terminal device, the corresponding capability information is included in the capability message 2 In the capability message 2, the IE corresponding to the radio access technology a is included, and the capability information of the radio access technology a is included in the IE. The capability information of the radio access technology a is not included in the capability message 1, and the capability message 1 may not include the IE corresponding to the radio access technology a.
在第二种实现方式的一种实施例中，还可以包括指示信息。对于N个能力消息中的每个能力消息来说，如果包括了相应的能力信息，那么就可以包括该能力信息对应的IE，例如该能力信息就可以位于该能力信息对应的IE中，而如果一个能力消息不包括相应的能力信息，那么该能力消息就可以不包括该能力信息对应的IE，但是包括一个指示信息，指示该能力信息在其他能力消息中发送，或指示该能力信息对应的IE在其他能力消息中发送。In an embodiment of the second implementation manner, the information may further be included. For each capability message of the N capability messages, if the corresponding capability information is included, the IE corresponding to the capability information may be included, for example, the capability information may be located in the IE corresponding to the capability information, and if A capability message does not include the corresponding capability information, so the capability message may not include the IE corresponding to the capability information, but includes an indication information indicating that the capability information is sent in other capability messages, or an IE corresponding to the capability information Sent in other capability messages.
具体的，能力消息的第二种实现方式下，指示信息可以通过选择(CHOICE)类型实现，CHOICE类型包括两个选项，可以通过CHOICE类型包括两个选项来指示不同的内容。例如，若第一部分能力信息在本能力消息中发送，或第一部分能力信息在第一能力消息中发送，则选择CHOICE类型的第一选项，该第一选项可以为第一能力信息对应的IE，第一能力信息就可以位于第一能力信息对应的IE中；若第一部分能力信息在其他能力消息中发送，或第一部分能力信息在第二能力消息中发送，则选择CHOICE类型的第二选项，该第二选项可以为指示信息，指示第一能力信息在其他能力消息中发送，或指示第一能力信息在第二能力消息中发送，第一能力信息就可以位于第一能力信息对应的IE中。Specifically, in the second implementation manner of the capability message, the indication information may be implemented by selecting (CHOICE) type. The CHOICE type includes two options, and the CHOICE type includes two options to indicate different contents. For example, if the first part of the capability information is sent in this capability message, or the first part of the capability information is sent in the first capability message, a first option of the CHOICE type is selected, and the first option may be an IE corresponding to the first capability information. The first capability information may be located in the IE corresponding to the first capability information; if the first part of the capability information is sent in another capability message, or the first part of the capability information is sent in the second capability message, the second option of the CHOICE type is selected, The second option may be indication information, indicating that the first capability information is sent in another capability message, or indicating that the first capability information is sent in the second capability message, and the first capability information may be located in the IE corresponding to the first capability information. .
具体的，在能力消息的第二种实现方式下，包括但不限于两种终端设备指示能力消息的方式：Specifically, in the second implementation manner of the capability message, there are but are not limited to two ways for the terminal device to indicate the capability message:
2a、方式B1。2a, Mode B1.
在方式B1下，提供一种指示信息，例如依然称为第一指示信息。In manner B1, an indication information is provided, for example, it is still called first indication information.
其中，可以不必关注第一指示信息的取值，只要是规定好的一种指示标识即可。It is not necessary to pay attention to the value of the first indication information, as long as it is a prescribed indication identifier.
或者，也可以设置第一指示信息的取值，例如将第一指示信息的取值设置为第三值。通过关注第一指示信息的取值，可以尽量避免出错，例如可尽量避免将其他的信息误认为是第一指示信息。作为一种实施方式，第一指示信息可以通过枚举类型实现。例如可以将第三值设置为true(例如，形式为ENUMERATED{ture})，或者设置为支持(supported)(例如，形式为ENUMERATED{supported})，具体的不作限制。对于第一指示信息取值为第三值的指示方式，可参考前文的介绍。当然，第一指示信息也可以通过其他方式实现，例如也可以通过布尔类型实现等，具体的也不作限制。Alternatively, the value of the first instruction information may also be set, for example, the value of the first instruction information is set to a third value. By paying attention to the value of the first indication information, errors can be avoided as much as possible, for example, other information can be avoided from being mistaken for the first indication information. As an implementation manner, the first indication information may be implemented by using an enumeration type. For example, the third value may be set to true (for example, the form is ENUMERATED {ture}) or set to supported (for example, the form is ENUMERATED {supported}), and the specific value is not limited. For the indication method in which the first instruction information has a third value, reference may be made to the foregoing description. Of course, the first indication information may also be implemented by other methods, for example, it may also be implemented by a Boolean type, and the like is not specifically limited.
2b、方式B2。2b, Mode B2.
在方式B2下，提供两种指示信息，分别称为第二指示信息和第三指示信息，其中，第二指示信息可以用于指示终端设备的第一部分能力信息在其他能力消息中发送，若存在第二指示信息，即存在终端设备的第一部分能力信息在其他能力消息中发送，那么，发送终端设备的第一部分能力信息的其他能力消息中还包括。In mode B2, two types of indication information are provided, which are called second indication information and third indication information, wherein the second indication information may be used to instruct the first piece of capability information of the terminal device to be sent in other capability messages. The second indication information, that is, the first part of the capability information of the existing terminal device is sent in another capability message, and then the other capability message that sends the first part of the capability information of the terminal device is also included.
若第一部分能力信息在本能力消息中发送，或第一部分能力信息在第一能力消息中发送，则选择CHOICE类型的第一选项，该第一选项可以为第一能力信息对应的IE，第一能力信息就可以位于第一能力信息对应的IE中；若第一部分能力信息在其他能力消息中发送，或第一部分能力信息在第二能力消息中发送，则选择CHOICE类型的第二选项，该第二选项可以为第二指示信息，指示第一能力信息在其他能力消息中发送，或指示第一能力信息在第二能力消息中发送，而第二能力消息就包括第一部分能力信息，还包括第三指示信息。If the first part of the capability information is sent in this capability message, or the first part of the capability information is sent in the first capability message, the first option of the CHOICE type is selected. The first option may be the IE corresponding to the first capability information. The capability information can be located in the IE corresponding to the first capability information; if the first part of the capability information is sent in another capability message, or the first part of the capability information is sent in the second capability message, the second option of the CHOICE type is selected. The two options may be the second indication information, indicating that the first capability information is sent in other capability messages, or the first capability information is sent in the second capability message, and the second capability message includes the first part of the capability information, and also includes the first Three instructions.
具体的，关于第二指示信息和第三指示信息的指示方式、取值方式、以及结合第一能力消息和第二 能力消息介绍第二指示信息和第三指示信息等的内容，以及方式B3的其他相关内容，均可前文的介绍。Specifically, regarding the indication method and value method of the second indication information and the third indication information, and introducing the contents of the second indication information and the third indication information in combination with the first capability message and the second capability message, and the manner of the method B3 Other related content can be introduced in the foregoing.
综上，如果能力消息采用能力消息的第一种实现方式，则更易于与已有的技术兼容，无需网络设备识别新的消息格式，更易于推广应用。而如果能力消息采用能力消息的第二种实现方式，则有助于减小能力消息的数据量，也就减少传输的数据量。其中，能力消息究竟采用哪种方式，例如可以通过协议规定，或者可以由网络设备设置，具体的不作限制。In summary, if the capability message adopts the first implementation method of the capability message, it is easier to be compatible with the existing technology, and it is not necessary for the network device to identify the new message format, and it is easier to promote and apply. If the capability message is implemented in the second implementation manner of the capability message, it will help reduce the amount of data in the capability message, and thus reduce the amount of data transmitted. Wherein, the capability message is adopted, for example, it may be specified by a protocol, or may be set by a network device, which is not specifically limited.
前文结合能力消息的实现方式介绍了指示能力消息的几种方式，下面再介绍指示能力消息的几种方式，因为下面介绍的方式与能力消息的实现方式之间没有太大的关联，所以单独介绍。The foregoing describes the several ways to indicate the capability message in combination with the implementation of the capability message. The following describes the several ways to indicate the capability message. Because the methods described below are not much related to the implementation of the capability message, they are introduced separately. .
方式C。Way C.
在方式C下，提供一种指示信息，N个能力消息中的每个能力消息都可以包括指示信息，该指示信息可以用于指示N个能力消息包括的终端设备的能力信息对应的所有无线接入技术，或者，指示信息用于指示N个能力消息包括的终端设备的能力信息对应的所有的版本。继续以第一能力消息和第二能力消息为例，则该指示信息用于指示第一能力消息和第二能力消息包括的终端设备的能力信息对应的所有无线接入技术，或者，该指示信息用于指示第一能力消息和第二能力消息包括的终端设备的能力信息对应的所有的版本。In mode C, an indication information is provided. Each of the N capability messages may include indication information, and the indication information may be used to indicate all wireless access points corresponding to the capability information of the terminal device included in the N capability messages. Into the technology, or the indication information is used to indicate all versions corresponding to the capability information of the terminal device included in the N capability messages. Taking the first capability message and the second capability message as an example, the indication information is used to indicate all radio access technologies corresponding to the capability information of the terminal device included in the first capability message and the second capability message, or the indication information It is used to indicate all versions corresponding to the capability information of the terminal device included in the first capability message and the second capability message.
例如，指示信息可以通过列表的形式实现，该列表中例如包括第一能力消息和第二能力消息包括的终端设备的能力信息对应的所有版本的版本标识信息，其中一个版本标识信息对应于终端设备的一个版本，版本标识信息例如为版本的版本号，或者为其他属性信息。或者，该列表中例如包括第一能力消息和第二能力消息包括的终端设备的能力信息对应的所有无线接入技术的RAT标识信息，其中一个RAT标识信息对应于一个无线接入技术，RAT标识信息例如为无线接入技术的名称，或者为其他属性信息。For example, the indication information may be implemented in the form of a list. The list includes, for example, version identification information of all versions corresponding to the capability information of the terminal device included in the first capability message and the second capability message, and one version identification information corresponds to the terminal device. For a version, the version identification information is, for example, the version number of the version, or other attribute information. Alternatively, the list includes, for example, RAT identification information of all radio access technologies corresponding to the capability information of the terminal device included in the first capability message and the second capability message, where one RAT identification information corresponds to one radio access technology and the RAT identifier The information is, for example, the name of the radio access technology, or other attribute information.
例如网络设备接收了一个能力消息，那么网络设备可以读取该能力消息所包括的能力信息，如果该指示信息所指示的某个版本的能力信息或某种无线接入技术对应的能力信息不包括在该能力消息中，则表示这部分能力信息包括在其他的能力消息中，网络设备就还需要接收其他的能力消息。从而，网络设备需要接收到终端设备在该指示信息所指示的所有无线接入技术下的能力信息，或者接收到终端设备对应于该指示信息所指示的所有版本的能力信息，才认为接收到了终端设备的完整能力信息。For example, if a network device receives a capability message, the network device can read the capability information included in the capability message. If the capability information of a certain version indicated by the indication information or the capability information corresponding to a certain radio access technology is not included The capability message indicates that this part of the capability information is included in other capability messages, and the network device needs to receive other capability messages. Therefore, the network device needs to receive the terminal device's capability information under all radio access technologies indicated by the instruction information, or the terminal device's capability information corresponding to all versions indicated by the instruction information, before it is considered that the terminal has been received. Full capability information for the device.
通过这种指示信息，较为简单明了地指示了N个能力消息应该包括的所有的能力信息，网络设备无论接收到哪个能力消息，都能够获得该指示信息，从而使得网络设备较为清楚是否获得了终端设备的完整能力信息。Through this indication information, all capability information that should be included in the N capability messages is indicated in a relatively simple and clear manner. The network equipment can obtain the indication information no matter which capability message is received, thereby making it more clear whether the network equipment has obtained the terminal. Full capability information for the device.
方式D。Way D.
在前文介绍了N个能力消息所包括的能力信息的三种可能的实现形式，其中，能力消息的第一种实现方式下的方式A1、方式A2和方式A3，能力消息的第二种实现方式下的方式B1和方式B2方式B3，以及方式C，都可以认为是适用于N个能力消息所包括的能力信息的第一种实现形式和第二种实现形式，也就是说，能力消息的第一种实现方式下的方式A1、方式A2和方式A3，能力消息的第二种实现方式下的方式B1和方式B2，以及方式C，可以适用于N个能力消息中的每个能力消息可以分别包括终端设备的至少一个版本的能力信息的情况，也可以适用于N个能力消息中的每个能力消息可以分别包括终端设备在至少一种无线接入技术下的能力信息的情况。而对于方式D，可以适用于N个能力消息所包括的能力信息的第三种实现形式，也就是说，方式D可以适用于对能力信息进行物理分割的情况。In the foregoing, three possible implementation forms of the capability information included in the N capability messages are introduced. Among them, manner A1, manner A2, and manner A3 in the first implementation manner of the capability message, and the second implementation manner of the capability message. The following modes B1, B2, B3, and C can be considered as the first and second implementation forms of the capability information included in the N capability messages, that is, the first capability form of the capability message. Method A1, Method A2, and Method A3 in one implementation manner, Method B1 and Method B2, and Method C in the second implementation manner of the capability message can be applied to each capability message of the N capability messages separately The case where the capability information of at least one version of the terminal device is included may also be applicable to the case where each of the N capability messages may include the capability information of the terminal device under at least one radio access technology. For the method D, the third implementation form of the capability information included in the N capability messages may be applied, that is, the method D may be applicable to a case where the capability information is physically divided.
在方式D下，提供一种指示信息，N个能力消息中的每个能力消息都可以包括指示信息，该指示信息可以指示该指示信息所在的能力消息在N个能力消息中的序列号，以及指示该指示信息所在的能力消息是否为N个能力消息中的最后一个能力消息。其中可以理解为，指示信息包括至少两个子信息，至少两个子信息中的一个子信息指示该指示信息所在的能力消息在N个能力消息中的序列号，至少两个子信息 中的另一个子信息指示该指示信息所在的能力消息是否为N个能力消息中的最后一个能力消息。In manner D, an indication information is provided, and each of the N capability messages may include indication information, and the indication information may indicate a sequence number of the capability message in which the indication information is located among the N capability messages, and Indicates whether the capability message where the indication information is located is the last capability message among the N capability messages. It can be understood that the indication information includes at least two pieces of sub-information, one of the at least two pieces of sub-information indicates the sequence number of the capability message in which the indication information is located in the N capability messages, and the other one of the at least two pieces of sub-information Indicates whether the capability message where the indication information is located is the last capability message among the N capability messages.
这里的“最后一个能力消息”，可以是指终端设备的发送顺序上的最后一个能力消息，相应的，能力消息的序列号也可以是根据终端设备的发送顺序确定的。以N个能力消息包括第一能力消息和第二能力消息为例，第一能力消息和第二能力消息中都可以包括该指示信息，第一能力消息包括的指示信息可以指示第一能力消息在N个能力消息中的序列号，以及指示第一指示信息所在的能力消息是否为N个能力消息中的最后一个能力消息，第二能力消息包括的指示信息可以指示第二能力消息在N个能力消息中的序列号，以及指示第二指示信息所在的能力消息是否为N个能力消息中的最后一个能力消息。The "last capability message" herein may refer to the last capability message in the sending order of the terminal device. Accordingly, the sequence number of the capability message may also be determined according to the sending order of the terminal device. Taking the N capability messages including the first capability message and the second capability message as an example, the first capability message and the second capability message may include the indication information, and the indication information included in the first capability message may indicate that the first capability message is in Sequence numbers in the N capability messages and whether the capability message where the first indication information is located is the last capability message in the N capability messages. The indication information included in the second capability message may indicate that the second capability message is in the N capabilities. The sequence number in the message and whether the capability message where the second indication information is located is the last capability message among the N capability messages.
例如，终端设备将终端设备的完整能力信息进行编码后，分割成了3个部分，分别通过3条能力消息发送，即，N＝3。其中，第一条能力消息包含编码后的能力信息的第一部分，则第一条能力消息中包括的指示信息可以指示{第一部分，非最后一部分}，同理，第二条能力消息包含编码后的能力信息的第二部分，第一条能力消息中包括的指示信息可以指示{第二部分，非最后一部分}，第三条能力消息包含编码后的能力信息的第三部分，第三条能力消息中包括的指示信息可以指示{第三部分，最后一部分}。可以理解为，每个指示信息所指示的前一部分是通过一个子信息指示的，每个指示信息指示的后一部分是通过另一个子信息指示的。这样设置指示信息，指示可以较为清楚。For example, after the terminal device encodes the complete capability information of the terminal device, it is divided into three parts and sent through three capability messages, that is, N = 3. Wherein, the first capability message includes the first part of the encoded capability information, the indication information included in the first capability message may indicate {the first part, not the last part}. Similarly, the second capability message includes the encoded capability information. The second part of the capability information, the indication information included in the first capability message may indicate {the second part, not the last part}, the third capability message contains the third part of the encoded capability information, and the third capability The indication information included in the message may indicate {third part, last part}. It can be understood that the former part indicated by each indication information is indicated by one sub-information, and the latter part indicated by each indication information is indicated by another sub-information. By setting the instructions in this way, the instructions can be clearer.
或者，第一条能力消息包含编码后的能力信息的第一部分，第一条能力消息中包括的指示信息可以指示{第一部分}，第二条能力消息包含编码后的能力信息的第二部分，第一条能力消息中包括的指示信息可以指示{第二部分}，第三条能力消息包含编码后的能力信息的第三部分，第三条能力消息中包括的指示信息可以指示{第三部分，最后一部分}。也就是，对于包括非最后一部分的编码后的能力信息的能力消息，可以通过“空”的方式来指示，该能力消息包括的编码后的能力信息为非最后一部分。这样设置指示信息，可以尽量减少能力消息所包括的数据量。Or, the first capability message includes the first part of the encoded capability information, the indication information included in the first capability message may indicate {the first part}, and the second capability message includes the second part of the encoded capability information, The indication information included in the first capability message may indicate {part II}, the third capability message includes the third part of the encoded capability information, and the indication information included in the third capability message may indicate {part III , Last part}. That is, the capability message including the non-last part of the encoded capability information may be indicated in an “empty” manner, and the encoded capability information included in the capability message is not the last part. Setting the instruction information in this way can minimize the amount of data included in the capability message.
或者，第一条能力消息包含编码后的能力信息的第一部分，第一条能力消息中包括的指示信息可以指示{第一部分，非最后一部分}，第二条能力消息包含编码后的能力信息的第二部分，第一条能力消息中包括的指示信息可以指示{第二部分，非最后一部分}，第三条能力消息包含编码后的能力信息的第三部分，第三条能力消息中包括的指示信息可以指示{第三部分}。也就是，对于包括最后一部分的编码后的能力信息的能力消息，可以通过“空”的方式来指示，该能力消息包括的编码后的能力信息为最后一部分。这样设置指示信息，可以尽量减少能力消息所包括的数据量。Alternatively, the first capability message contains the first part of the encoded capability information, and the indication information included in the first capability message may indicate {the first part, not the last part}, and the second capability message contains the encoded capability information. The second part, the indication information included in the first capability message may indicate {the second part, not the last part}, the third capability message contains the third part of the encoded capability information, and the third capability message includes The instruction information may indicate {third part}. That is, the capability message including the encoded capability information of the last part may be indicated in an “empty” manner, and the encoded capability information included in the capability message is the last part. Setting the instruction information in this way can minimize the amount of data included in the capability message.
如上只是对方式D的举例，本实施例对于指示信息的指示方式不做限定，只要能指示出需要的意思即可。The above is only an example of the method D. In this embodiment, the indication method of the indication information is not limited, as long as the required meaning can be indicated.
方式E。Way E.
方式E同样可以适用于N个能力消息所包括的能力信息的第三种实现形式，也就是说，方式E可以适用于对能力信息进行物理分割的情况。Method E can also be applied to the third implementation form of the capability information included in the N capability messages, that is, method E can be applied to the case where the capability information is physically divided.
在方式E下，提供一种指示信息，N个能力消息中的每个能力消息都可以包括指示信息，该指示信息可以指示该指示信息所在的能力消息在N个能力消息中的序列号，以及指示N的取值。其中可以理解为，指示信息包括至少两个子信息，至少两个子信息中的一个子信息指示该指示信息所在的能力消息在N个能力消息中的序列号，至少两个子信息中的另一个子信息指示N的取值。In manner E, a kind of indication information is provided. Each of the N capability messages may include indication information, and the indication information may indicate a sequence number of the capability message in the N capability messages, and Indicates the value of N. It can be understood that the indication information includes at least two pieces of sub-information. One of the at least two pieces of sub-information indicates the sequence number of the capability message in which the indication information is located in the N capability messages, and the other one of the at least two pieces of sub-information. Indicates the value of N.
这里的能力消息的序列号，可以是根据终端设备的发送顺序确定的。以N个能力消息包括第一能力消息和第二能力消息为例，第一能力消息和第二能力消息中都可以包括该指示信息，第一能力消息包括的指示信息可以指示第一能力消息在N个能力消息中的序列号，以及指示N的取值，第二能力消息包括的指示信息可以指示第二能力消息在N个能力消息中的序列号，以及指示N的取值。The sequence number of the capability message here may be determined according to the sending order of the terminal device. Taking the N capability messages including the first capability message and the second capability message as an example, the first capability message and the second capability message may include the indication information, and the indication information included in the first capability message may indicate that the first capability message is in The sequence numbers in the N capability messages and the value indicating N. The indication information included in the second capability message may indicate the sequence numbers of the second capability message in the N capability messages and the value indicating N.
例如，终端设备将终端设备的完整能力信息进行编码后，分割成了3个部分，分别通过3条能力消息 发送，即，N＝3。其中，第一条能力消息包含编码后的能力信息的第一部分，则第一条能力消息中包括的指示信息可以指示{第一部分，3}，同理，第二条能力消息包含编码后的能力信息的第二部分，第一条能力消息中包括的指示信息可以指示{第二部分，3}，第三条能力消息包含编码后的能力信息的第三部分，第三条能力消息中包括的指示信息可以指示{第三部分，3}。可以理解为，每个指示信息所指示的前一部分是通过一个子信息指示的，每个指示信息指示的后一部分是通过另一个子信息指示的。这样设置指示信息，指示可以较为清楚。For example, after the terminal device encodes the complete capability information of the terminal device, it is divided into three parts and sent through three capability messages, that is, N = 3. Wherein, the first capability message includes the first part of the encoded capability information, the indication information included in the first capability message may indicate {the first part, 3}. Similarly, the second capability message includes the encoded capability The second part of the information, the indication information included in the first capability message may indicate {second part, 3}, the third capability message contains the third part of the encoded capability information, and the third capability message includes The instruction information may indicate {third part, 3}. It can be understood that the former part indicated by each indication information is indicated by one sub-information, and the latter part indicated by each indication information is indicated by another sub-information. By setting the instructions in this way, the instructions can be clearer.
如上只是对方式E的举例，本实施例对于指示信息的指示方式不做限定，只要能指示出需要的意思即可。The above is only an example of the method E. In this embodiment, the indication method of the indication information is not limited, as long as the required meaning can be indicated.
前文介绍了指示能力信息的多种方式，在实际应用时，可以根据能力消息的实现方式选择相应的指示能力信息的方式。The foregoing describes the multiple ways of indicating capability information. In actual applications, you can choose the corresponding way of indicating capability information according to the implementation of the capability message.
另外，终端设备可能会多次向网络设备发送终端设备的能力信息，也就是说，图4所示的实施例可能会发生多次。那么，网络设备接收来自终端设备的能力信息后，需要区分哪些能力信息是哪一次发送的，否则如果将不同次发送的能力信息相混淆，可能会导致网络设备得到错误的能力信息。那么在本实施例中，可以考虑在每次发送的能力消息中添加标识信息，该标识信息用于指示能力信息所属的发送次数，也就是指示能力信息是哪一次发送的。例如，终端设备一次发送N个能力消息，则可以在N个能力消息中的每个能力消息中都添加标识信息，这N个能力消息中所添加的标识信息都是相同的，指示的都是能力消息是本次发送的。其中，终端设备一次发送N个能力消息，只是说明这N个能力消息包括的能力信息是终端设备的完整能力信息，并不是限制这N个能力消息一定要同时发送，实际上，这N个能力消息可以同时发送，或者也可以分时发送，具体的不作限制。例如，N个能力消息包括第一能力消息和第二能力消息，第一能力消息和第二能力消息均包括标识信息，则第一能力消息和第二能力信息包括的标识信息是相同的，因为一次发送的能力消息包括的标识信息相同。In addition, the terminal device may send the capability information of the terminal device to the network device multiple times, that is, the embodiment shown in FIG. 4 may occur multiple times. Then, after receiving the capability information from the terminal device, the network device needs to distinguish which capability information was sent which time. Otherwise, if the capability information sent at different times is confused, the network device may get wrong capability information. Then, in this embodiment, it may be considered to add identification information to the capability message sent each time, and the identification information is used to indicate the number of transmission times to which the capability information belongs, that is, to indicate when the capability information is transmitted. For example, if a terminal device sends N capability messages at a time, identification information can be added to each capability message in the N capability messages. The identification information added in the N capability messages is the same, and the indications are all The capability message is sent this time. Among them, the terminal device sends N capability messages at a time, only to indicate that the capability information included in the N capability messages is the complete capability information of the terminal device, and does not limit the N capability messages that must be sent at the same time. Messages can be sent at the same time, or they can be sent at different times. For example, if the N capability messages include the first capability message and the second capability message, and the first capability message and the second capability message both include identification information, the identification information included in the first capability message and the second capability information is the same because The capability information sent at one time includes the same identification information.
例如标识信息可以通过值标签(valuetag)实现，标识信息可以是时间信息，则一个标识信息就表示一次发送的时刻或时间段，或者标识信息也可以是序列号，例如序列号可以取从1～n的值，第一次发送对应的标识信息为1，第二次发送对应的标识信息为2，以此类推，或者标识信息还可以通过其他方式实现。以标识信息是序列号为例，例如，网络设备第一次请求终端设备发送能力信息时，终端设备将第一次发送对应的标识信息设置为1，如果终端设备在第一次发送能力信息时是通过多条能力消息发送，则终端设备可以将1添加到其中的每条能力消息中，网络设备第二次请求终端设备发送能力信息时，终端设备将第二次发送对应的标识信息设置为2，如果终端设备在第一次发送能力信息时是通过多条能力消息发送，则终端设备可以将2添加到其中的每条能力消息中，以此类推，网络设备接收来自终端设备的能力消息后，可以将包括了相同的标识信息的能力消息包括的能力信息进行组合，以得到终端设备不同次发送的完整能力信息，也可以避免非同一次上报的能力消息错误的组合导致的译码问题。For example, identification information can be implemented by value tags. The identification information can be time information. One identification information indicates the time or time period of a transmission, or the identification information can be a serial number. For example, the serial number can be from 1 to The value of n, the corresponding identification information for the first transmission is 1, the corresponding identification information for the second transmission is 2, and so on, or the identification information can also be implemented in other ways. Take the identification information as a serial number as an example. For example, when a network device first requests a terminal device to send capability information, the terminal device sets the corresponding identification information for the first transmission to 1. If the terminal device sends capability information for the first time, Is sent through multiple capability messages, the terminal device can add 1 to each of the capability messages. When the network device requests the terminal device to send capability information for the second time, the terminal device sets the identification information corresponding to the second transmission to 2. If the terminal device sends the capability information through multiple capability messages for the first time, the terminal device can add 2 to each of the capability messages, and so on, and the network device receives the capability message from the terminal device. Then, the capability information included in the capability message including the same identification information can be combined to obtain the complete capability information sent by the terminal device different times, and the decoding problem caused by the wrong combination of capability messages that are not reported at the same time can be avoided .
其中，对于如前介绍的方式C，如果在N个能力消息中添加标识信息，那么一种添加方式是将标识信息添加到方式C的指示信息中，相当于在指示信息中包括标识信息，这样设置，可以使得网络设备能够同时获得指示信息和标识信息，加快网络设备的识别速度。当然另外的添加方式可以是不添加到指示信息中，而是单独添加标识信息。对于方式D和方式E来说也是同样，标识信息可以添加到指示信息中，或者也可以在能力消息中单独存在。其中，在指示信息中添加标识信息，可以理解为，指示信息所在的是能力消息中的一个比特域，例如称为指示域，那么可以将标识信息也添加到该指示域中。当然，如果在未添加标识信息时，该指示域的容量小于指示信息和标识信息的总的数据量，那么可以将该指示域进行扩展后再添加标识信息，该指示域扩展后的容量大于或等于指示信息和标识信息的总的数据量。Among them, for the manner C introduced earlier, if identification information is added to the N capability messages, one way of adding is to add the identification information to the indication information of the manner C, which is equivalent to including the identification information in the indication information. The setting can enable the network device to obtain the instruction information and the identification information at the same time, and accelerate the recognition speed of the network device. Of course, another way of adding may be not to add to the instruction information, but to add identification information separately. The same is true for the manner D and the manner E, the identification information may be added to the indication information, or may also exist separately in the capability message. Wherein, adding the identification information to the indication information can be understood as that the indication information is located in a bit field in the capability message, for example, it is referred to as the indication field, and then the identification information can also be added to the indication field. Of course, if the capacity of the indication field is smaller than the total data amount of the indication information and the identification information when the identification information is not added, then the indication field may be extended and then the identification information is added. The expanded capacity of the indication field is greater than or It is equal to the total data amount of the indication information and the identification information.
以在方式D的能力消息的指示信息中添加标识信息为例。例如，终端设备将终端设备的完整能力信 息进行编码后，分割成了3个部分，分别通过3条能力消息发送，即，N＝3。其中，第一条能力消息包含编码后的能力信息的第一部分，还包括标识信息，则第一条能力消息中包括的指示域可以指示{标识信息，第一部分，非最后一部分}，同理，第二条能力消息包含编码后的能力信息的第二部分，第一条能力消息中包括的指示域可以指示{标识信息，第二部分，非最后一部分}，第三条能力消息包含编码后的能力信息的第三部分，第三条能力消息中包括的指示域可以指示{标识信息，第三部分，最后一部分}。这样设置指示信息和标识信息，指示可以较为清楚。Take, for example, adding identification information to the indication information of the capability message in mode D. For example, after the terminal device encodes the complete capability information of the terminal device, it is divided into three parts and sent through three capability messages, that is, N = 3. Wherein, the first capability message includes the first part of the encoded capability information and also includes identification information, the indication field included in the first capability message may indicate {identification information, first part, non-last part}, for the same reason, The second capability message contains the second part of the encoded capability information. The indication field included in the first capability message may indicate {identification information, second part, not the last part}, and the third capability message contains the encoded The third part of the capability information, and the indication field included in the third capability message may indicate {identification information, third part, last part}. By setting instruction information and identification information in this way, the instructions can be clearer.
以在方式E的能力消息的指示信息中添加标识信息为例。终端设备将终端设备的完整能力信息进行编码后，分割成了3个部分，分别通过3条能力消息发送，即，N＝3。其中，第一条能力消息包含编码后的能力信息的第一部分，还包括标识信息，则第一条能力消息中包括的指示域可以指示{标识信息，第一部分，3}，同理，第二条能力消息包含编码后的能力信息的第二部分，第一条能力消息中包括的指示域可以指示{标识信息，第二部分，3}，第三条能力消息包含编码后的能力信息的第三部分，第三条能力消息中包括的指示域可以指示{标识信息，第三部分，3}。这样设置指示信息和标识信息，指示可以较为清楚。Take, for example, adding identification information to the indication information of the capability message in Mode E. After the terminal device encodes the complete capability information of the terminal device, it is divided into three parts and sent through three capability messages, that is, N = 3. Among them, the first capability message includes the first part of the encoded capability information, and also includes identification information. The indication field included in the first capability message may indicate {identification information, first part, 3}, for the same reason, the second The capability message contains the second part of the encoded capability information. The indication field included in the first capability message can indicate {identification information, part 2, 3}, and the third capability message contains the first part of the encoded capability information. In three parts, the indication field included in the third capability message may indicate {identification information, part three, 3}.
