具体实施方式detailed description

首先指出的是，终端的能力可以分为无线能力和核心网能力两种。对于无线能力，终端可根据网络的请求上报终端的无线能力。对于核心网能力，终端可在注册时上报终端的网络能力。The first point is that the capabilities of terminals can be divided into wireless capabilities and core network capabilities. As for the wireless capability, the terminal can report the wireless capability of the terminal according to the request of the network. For the core network capability, the terminal can report the network capability of the terminal during registration.

终端可以支持多个频带(Band)和频率(frequency)。随着载波聚合(Carrier Aggregation，CA)和双连接(Dual Connectivity，DC)等技术的引入，需要排列组合各种可能的频带组合，而且各个终端厂家支持的频带组合可能还各不相同，造成无线能力特别庞大。另外，随着网络的演进，越来越多的特性被引入网络，不同的特性往往需要不同的无线能力和网络能力。对于相关的网络特性，终端需要将是否支持的信息告知网络。The terminal can support multiple bands and frequencies. With the introduction of carrier aggregation (CA) and dual connectivity (DC) and other technologies, it is necessary to arrange and combine various possible frequency band combinations, and the frequency band combinations supported by each terminal manufacturer may also be different, resulting in wireless The capacity is particularly huge. In addition, as the network evolves, more and more features are introduced into the network, and different features often require different wireless capabilities and network capabilities. For related network characteristics, the terminal needs to inform the network of whether it supports it.

一般来说，每个出厂的终端都有设备标识信息，比如国际移动设备识别码(International Mobile Equipment Identity，IMEI)。IMEI中可包含类型分配码(Type Allocation Code，TAC)，该TAC通常由8位数字组成(早期是6位)，是区分终端品牌和型号的编码，该TAC由GSMA及其授权机构分配。其中该TAC的前两位又称为分配机构标识(Reporting Body Identifier)，是授权IMEI分配机构的代码，如01为美国CTIA，35为英国BABT，86为中国TAF。通过TAC，可以唯一标识同一终端型号。而同一终端型号的终端能力往往是相同的。In general, each terminal that leaves the factory has equipment identification information, such as International Mobile Equipment Identity (IMEI). The IMEI may include a Type Allocation Code (TAC). The TAC usually consists of 8 digits (early 6 digits). It is a code that distinguishes the terminal brand and model. The TAC is assigned by GSMA and its authorized agencies. Among them, the first two digits of the TAC are also called the reporting agency identifier (Reporting Body Identifier), which is the code that authorizes the IMEI distribution agency. With TAC, the same terminal model can be uniquely identified. The terminal capabilities of the same terminal model are often the same.

IMEI中还可以包含软件版本号(Software Version Number，SVN)，该SVN可以区分同型号终端出厂时使用的不同软件版本。SVN仅在部分品牌的部分机型中存在。不同SVN可以对应不同的终端能力。The IMEI may also include a software version number (SVN). The SVN can distinguish different software versions used by the same type of terminal when leaving the factory. SVN only exists in some models of some brands. Different SVNs can correspond to different terminal capabilities.

为了减少终端能力上报带来的开销，可为终端设置能够指示终端能力的标识信息。一种终端能力信令优化的方法是终端仅向网络上报指示终端能力的标识信息。网络通过指示终端能力的标识信息可映射得到终端能力。终端能力标识信息可以是指示终端能力的能力标识信息。In order to reduce the overhead caused by the terminal capability reporting, the terminal may be provided with identification information capable of indicating the terminal capability. A method for optimizing terminal capability signaling is that the terminal only reports identification information indicating the capability of the terminal to the network. The network can obtain the terminal capabilities through the identification information indicating the terminal capabilities. The terminal capability identification information may be capability identification information indicating a terminal capability.

本公开实施例中，终端能力的标识信息(可简称为终端能力标识信息)可以用于识别终端能力。终端能力标识信息与终端能力信息之间存在映射的关系，通过终端能力标识信息可以映射出终端能力。终端能力标识信息可以映射出一组终端能力或完整的终端能力。由于终端能力标识信息大小比终端能力小，可以达到节省能力信令优化的效果。In the embodiment of the present disclosure, the identification information of the terminal capabilities (may be referred to as terminal capability identification information) may be used to identify the terminal capabilities. There is a mapping relationship between the terminal capability identification information and the terminal capability information, and the terminal capability can be mapped through the terminal capability identification information. The terminal capability identification information may map a group of terminal capabilities or a complete terminal capability. Because the size of the terminal capability identification information is smaller than the terminal capability, the effect of optimizing the capability saving signaling can be achieved.

可选的，一个终端可以具有一个或多个终端能力标识信息。Optionally, a terminal may have one or more terminal capability identification information.

本公开实施例中，服务网络是为终端提供接入的网络，可以是网络运营主体的网络或者是专用网络，可以是公众通信网络也可以是私有通信网络。可选的，服务网络的标识可以是公共陆地移动网络(Public Land Mobile Network，PLMN)或其他(比如私有通信网络自己配置的标识)。In the embodiment of the present disclosure, the service network is a network that provides access for terminals, and may be a network of a network operation subject or a private network, a public communication network, or a private communication network.

为了减少终端能力上报带来的开销，可为终端设置能够指示终端能力的标识信息。一种终端能力信令优化的方法是终端仅向网络上报指示终端能力的标识信息。网络通过指示终端能力的标识信息可映射得到终端能力。终端能力标识信息可以是指示终端能力的能力标识信息。当网络没有终端能力的标识信息映射的终端能力时，网络可以向终端获取终端能力。然后网络可以建立终端能力的能力标识信息与终端能力的映射关系。In order to reduce the overhead caused by the terminal capability reporting, the terminal may be provided with identification information capable of indicating the terminal capability. A method for optimizing terminal capability signaling is that the terminal only reports identification information indicating the capability of the terminal to the network. The network can obtain the terminal capabilities through the identification information indicating the terminal capabilities. The terminal capability identification information may be capability identification information indicating a terminal capability. When the network does not have the terminal capability mapped by the identification information of the terminal capability, the network can obtain the terminal capability from the terminal. The network can then establish a mapping relationship between the capability identification information of the terminal capabilities and the terminal capabilities.

为了减少终端上报的无线能力，RAN(无线接入网)网元可以仅向终端获取终端的能力的子集。比如对于RAN网元不支持的无线能力(比如频率band)或者策略上不会调度的频率band组合，RAN网元可以不请求终端上报。所以，RAN获取的终端能力可能是终端能力的子集。不同的RAN节点的能力不同，所以获取的终端能力也不同。In order to reduce the wireless capability reported by the terminal, the RAN (radio access network) network element may obtain only a subset of the terminal's capability from the terminal. For example, for a wireless capability (such as a frequency band) that is not supported by the RAN network element or a combination of frequency bands that are not scheduled in the policy, the RAN network element may not request the terminal to report. Therefore, the terminal capabilities acquired by the RAN may be a subset of the terminal capabilities. Different RAN nodes have different capabilities, so the acquired terminal capabilities are also different.

本公开实施例可以解决如下问题：The embodiments of the present disclosure can solve the following problems:

问题1：当RAN网元向终端获取的终端能力是终端能力标识信息映射的终端能力的子集时。网络根据获得的终端能力建立终端能力标识信息与获得的终端能力子集的映射关系时，就会导致错误。当终端进入空闲态又接入新的RAN节点时，新的RAN节点会误解终端能力子集是终端的完整能力集合。从而影响资源调度和用户的使用体验。Problem 1: When the terminal capabilities acquired by the RAN network element from the terminal are a subset of the terminal capabilities mapped by the terminal capability identification information. When the network establishes a mapping relationship between the terminal capability identification information and the obtained terminal capability subset according to the acquired terminal capabilities, an error will result. When the terminal enters the idle state and accesses a new RAN node, the new RAN node will misunderstand that the terminal capability subset is the complete capability set of the terminal. Thus affecting resource scheduling and user experience.

问题2：一个终端可以配置有多个能力标识，分别对应不同的能力集合。比如对应不同的运营商，可以有不同的能力集合，分别对应不同的终端能力。但终端接入一个运营商网络时，可以只上报一个能力标识。每个运营商支持的RAT Type不同，所需要的无线能力也不同。终端上完整的能力集对运营商网络来说是冗余的。比如像***上报CDMA的无线能力时没有价值的。所以完整的终端能力并不一定是当前终端能力标识映射的终端能力。Problem 2: A terminal can be configured with multiple capability identifiers, each corresponding to a different capability set. For example, corresponding to different operators, there can be different sets of capabilities, respectively corresponding to different terminal capabilities. However, when the terminal accesses an operator's network, it can report only one capability identifier. Each operator supports different types of RATs and requires different wireless capabilities. The complete set of capabilities on the terminal is redundant to the operator's network. For example, China Unicom has no value in reporting CDMA wireless capabilities. Therefore, the complete terminal capability is not necessarily the terminal capability mapped by the current terminal capability identifier.

The first communication device may include, but is not limited to, at least one of the following: a terminal, a terminal capable relay, a relay capable terminal, a RAN network element (such as gNB, eNB), and a CN network element (such as AMF, MME). As shown in Figure 2, it includes the following steps:

步骤201、获取能力请求信息，其中，所述能力请求信息包括：请求获取完整的终端能力的指示信息、能力请求筛选参数的指示信息、跳过或忽略的能力请求筛选参数、第一条件、回退频带是否上报指示信息、获取终端能力标识对应的终端能力的指示信息、终端能力标识信息和能力信令优化是否支持的信息中的至少一项，其中，所述能力请求筛选参数的指示信息所述筛选条件指示信息用于指示跳过或者忽略能力请求筛选参数；Step 201: Acquire capability request information, where the capability request information includes: indication information for requesting to acquire complete terminal capabilities, indication information for capability request screening parameters, skipped or ignored capability request screening parameters, first condition, response Whether at least one of the indication information of the backband frequency band, the indication information of acquiring the terminal capability corresponding to the terminal capability identifier, the terminal capability identification information, and the capability signaling optimization support information is supported, wherein the indication information of the capability request screening parameter is The filtering condition indication information is used to indicate skipping or ignoring capability request filtering parameters;

步骤202、根据所述能力请求信息执行终端能力的相关操作。Step 202: Perform a related operation of the terminal capability according to the capability request information.

一种实施方式中，上述获取能力请求信息可以是从以下至少一项获取：RAN网元、CN网元、AMF、MME、gNB、eNB。例如，第一通信设备为终端时，可从CN网元或RAN网元接收能力请求信息。例如，第一通信设备为RAN网元时，可从CN网元或其他RAN网元接收能力请求信息。例如，第一通信设备为CN网元时，可从其他CN网元或RAN网元接收能力请求信息。In an implementation manner, the foregoing capability request information may be acquired from at least one of the following: a RAN network element, a CN network element, an AMF, an MME, a gNB, and an eNB. For example, when the first communication device is a terminal, the capability request information may be received from a CN network element or a RAN network element. For example, when the first communication device is a RAN network element, the capability request information may be received from a CN network element or another RAN network element. For example, when the first communication device is a CN network element, the capability request information may be received from another CN network element or a RAN network element.

一种实施方式中，上述终端能力标识信息可以当前终端能力标识。所述当前终端能力标识可以理解为至少以下一项：当前终端能力对应的终端能力标识信息、有效的终端能力标识信息、最新的终端能力标识信息、终端发送给网络的最新的终端能力标识、网络分配的最新的终端能力标识、第一通信设备发送的终端能力标识信息、第一通信设备最新发送的终端能力标识信息。进一步地，获取终端能力标识对应的终端能力的指示信息可以是获取终端当前终端能力标识对应的终端能力的指示信息。In an implementation manner, the foregoing terminal capability identification information may be a current terminal capability identification.

Further, the indication information of acquiring the terminal capability corresponding to the terminal capability identifier may be the indication information of acquiring the terminal capability corresponding to the current terminal capability identifier of the terminal.

一种实施方式中，终端可能配置了多个能力标识，不同的能力标识映射的终端的能力不同，完整的终端能力可能并不是终端能力标识映射的终端能力。不难理解，可以通过显示地指示获取终端能力标识对应的所有终端能力的指示信息可以保证获得终端能力标识映射的终端能力。In one embodiment, the terminal may be configured with multiple capability identifiers, and the capabilities of the terminals mapped by different capability identifiers are different. The complete terminal capability may not be the terminal capability mapped by the terminal capability identifier. It is not difficult to understand that, by displaying the indication information indicating that all terminal capabilities corresponding to the terminal capability identifier are obtained, it is possible to ensure that the terminal capabilities mapped by the terminal capability identifier are obtained.

一种实施方式中，所述终端能力的相关操作也可以称作终端能力获取的相关操作。In an implementation manner, the related operations of the terminal capabilities may also be referred to as related operations of the terminal capability acquisition.

一种实施方式中，可以通过请求完整的终端能力的指示信息执行终端能力获取的相关操作，比如获取完整的终端能力。例如：第一通信设备为RAN网元。当CN网元没有终端能力标识信息映射的终端能力集时，CN网元可以指示RAN网元获取终端的完整能力集。不难理解，CN网元收到RAN网元发送的终端的完整能力集后可以建立终端能力标识与完整能力集之间的映射关系。该实施方式中，可以实现CN网元指示RAN网元获取终端的完整能力集。该实施方式中，可以在CN网元与RAN网络间的接口消息(如S1消息(如初始UE上下文建立请求消息)，和/或NG消息(如初始UE上下文建立请求消息))中包含请求获取完整的终端能力的指示信息。例如，第一通信设备为终端。当RAN网元没有终端能力标识信息映射的终端能力集时，RAN网元可以指示终端上报终端的完整能力集。不难理解，RAN网元收到终端的完整能力集后可以建立终端能力标识与完整能力集之间的映射关系和/或将获取到的终端能力发送给CN网元。该实施方式中，可以在UE能力查询(UE capability enquiry)消息中包含请求获取完整的终端能力的指示信息。In an implementation manner, related operations of acquiring terminal capabilities may be performed by requesting indication information of the complete terminal capabilities, such as acquiring complete terminal capabilities. For example: the first communication device is a RAN network element. When the CN network element does not have the terminal capability set mapped with the terminal capability identification information, the CN network element may instruct the RAN network element to obtain the complete capability set of the terminal. It is not difficult to understand that after receiving the complete capability set of the terminal sent by the RAN network element, the CN network element can establish a mapping relationship between the terminal capability identifier and the complete capability set. In this implementation manner, the CN network element can instruct the RAN network element to obtain the complete capability set of the terminal. In this implementation manner, an interface message (such as an S1 message (such as an initial UE context establishment request message) and / or an NG message (such as an initial UE context establishment request message)) between the CN network element and the RAN network may include a request for acquisition Complete terminal capability indication. For example, the first communication device is a terminal. When the RAN network element does not have the terminal capability set mapped with the terminal capability identification information, the RAN network element may instruct the terminal to report the complete capability set of the terminal. It is not difficult to understand that after receiving the complete capability set of the terminal, the RAN network element can establish a mapping relationship between the terminal capability identifier and the complete capability set and / or send the acquired terminal capability to the CN network element. In this embodiment, the UE capability inquiry (UE capability enquiry) message may include instruction information for requesting to obtain complete terminal capabilities.

另一种实施方式中，可以通过终端能力标识信息获取终端能力。例如：第一通信设备为终端。当RAN网元获取终端的终端能力标识信息但终端能力标识信息无映射的终端能力或当RAN网元获取终端支持能力信令优化的信息时，RAN网元可以根据终端能力标识信息向终端请求终端能力。终端可以根据RAN网元指示的终端能力标识信息，向RAN网元返回终端能力标识映射的终端能力，其中，所述终端能力可以是一个终端能力集合。该实施方式中，可以在终端能力查询消息中包含终端能力标识。In another implementation manner, the terminal capability may be acquired through the terminal capability identification information. For example: the first communication device is a terminal. When the RAN network element obtains the terminal capability identification information of the terminal but the terminal capability identification information has no mapped terminal capability or when the RAN network element obtains information on the terminal support capability signaling optimization, the RAN network element may request the terminal from the terminal according to the terminal capability identification information ability. The terminal may return the terminal capability identification mapped terminal capability to the RAN network element according to the terminal capability identification information indicated by the RAN network element, where the terminal capability may be a terminal capability set. In this embodiment, the terminal capability identification message may be included in the terminal capability query message.

另一种实施方式中，可以通过获取终端能力标识对应的终端能力的指示信息执行终端能力获取的相关操作，比如获取终端能力标识对应的终端能力。例如：第一通信设备为终端。RAN网元可以根据一个指示信息向终端请求终端能力，其中，所述指示信息用于向终端请求当前终端能力标识映射的终端能力集。终端根据所述指示信息，可以向RAN网元返回当前终端能力标识映射的终端能力集。另外，上述指示信息可以是1比特指示信息，当然，对此不作限定。该实施方式中，可以在终端能力查询消息中包含获取终端能力标识对应的终端能力的指示信息。In another implementation manner, related operations of acquiring terminal capabilities may be performed by acquiring terminal capability indication information corresponding to the terminal capability identifier, such as acquiring terminal capabilities corresponding to the terminal capability identifier. For example: the first communication device is a terminal. The RAN network element may request the terminal capabilities from the terminal according to an instruction information, where the instruction information is used to request the terminal for the terminal capability set mapped by the current terminal capability identity. According to the instruction information, the terminal may return the terminal capability set mapped to the current terminal capability identifier to the RAN network element. In addition, the foregoing instruction information may be 1-bit instruction information, and of course, it is not limited thereto. In this embodiment, the terminal capability query message may include instruction information for acquiring the terminal capability corresponding to the terminal capability identifier.

另一种实施方式中，可以通过能力信令优化是否支持的信息执行终端能力获取的相关操作。其中，能力信令优化是否支持的信息指示支持可以是指以下至少一项：终端具有能力信令优化能力、网络具有能力信令优化能力、终端和网络都具有能力信令优化能力。例如：第一通信设备为终端。终端可以从CN网元(比如注册过程中)或RAN网元(比如无线资源控制(Radio Resource Control，RRC)过程、***消息广播)中获得能力信令优化是否支持的信息。能力信令优化是否支持的信息指示支持时，当收到网络发送的能力获取请求(如UE能力查询的RRC消息)时，终端可以跳过或忽略能力请求筛选参数，向网络返回当前终端能力标识映射的终端能力或者完整的终端能力。所述完整的终端能力可以是一定条件下的完整终端能力。跳过或忽略能力请求筛选参数可以是一个或多个请求筛选参数。In another implementation manner, information related to whether to support terminal capability acquisition operations may be performed through capability signaling to optimize whether the information is supported. The information indicating whether the capability signaling optimization is supported may indicate at least one of the following: the terminal has the capability signaling optimization capability, the network has the capability signaling optimization capability, and both the terminal and the network have the capability signaling optimization capability. For example: the first communication device is a terminal. The terminal can obtain information on whether the capability signaling optimization is supported from a CN network element (for example, during registration) or a RAN network element (for example, Radio Resource Control (RRC) process, system message broadcast). When the capability signaling optimization support information indicates support, when receiving a capability acquisition request (such as an RRC message for UE capability query) sent by the network, the terminal can skip or ignore the capability request filtering parameters and return the current terminal capability identifier to the network Mapped terminal capabilities or complete terminal capabilities. The complete terminal capability may be a complete terminal capability under certain conditions. The skip or ignore capability request filtering parameter can be one or more request filtering parameters.

另一种实施方式中，可以通过能力请求筛选参数的指示信息行终端能力获取的相关操作。例如：第一通信设备为终端。终端根据能力请求筛选参数的指示信息跳过或忽略能力请求筛选参数，向网络返回完整的终端能力。In another implementation manner, a related operation of acquiring the terminal's capability by indicating the information requested by the capability request screening parameter can be performed. For example: the first communication device is a terminal. The terminal skips or ignores the capability request filtering parameter according to the indication information of the capability request filtering parameter, and returns the complete terminal capability to the network.

另一种实施方式中，可以通过跳过或忽略的能力请求筛选参数执行终端能力获取的相关操作。例如：第一通信设备为终端。终端根据指示的跳过或忽略的能力请求筛选参数跳过或忽略能力请求筛选参数，向网络返回完整的终端能力或满足一定条件的终端能力。所述一定条件可以是未指示跳过或忽略的能力请求筛选参数。In another implementation manner, the related operations of acquiring the terminal's capabilities can be performed through the skipped or ignored capability request screening parameters. For example: the first communication device is a terminal. The terminal skips or ignores the capability request screening parameter according to the indicated skip or ignore capability request screening parameter, and returns the complete terminal capability or the terminal capability meeting certain conditions to the network. The certain condition may be a capability request screening parameter that does not indicate skip or ignore.

另一种实施方式中，所述能力请求筛选参数可以理解为如下至少一项：根据所述能力筛选参数的要求发送终端能力和不需要上报完整的能力。通过能力请求筛选参数可以当前发送的能力缩减能力信令开销的目的。另外，所述能力请求筛选参数也可以称为能力缩减参数。In another implementation manner, the capability request screening parameter may be understood as at least one of the following: sending a terminal capability according to a requirement of the capability screening parameter and a capability that does not need to be reported intact. The capability request screening parameter can reduce the capability signaling overhead for the capability currently being sent. In addition, the capability request screening parameter may also be referred to as a capability reduction parameter.

另一种实施方式中，可以通过指示第一条件执行终端能力获取的相关操作，比如获取满足第一条件的终端能力。In another implementation manner, related operations of acquiring terminal capabilities may be performed by instructing the first condition, such as acquiring terminal capabilities that meet the first condition.

一种实施方式中，上述第一条件可以是预先配置的。In one embodiment, the first condition may be pre-configured.

Specifically, the radio access technology type information, the radio access network type information, the communication network type information, and the network age information are as described above, and are not repeated here. The network type information may be used to instruct acquiring terminal capabilities corresponding to the network type at the terminal (for example, complete terminal capabilities corresponding to the specified network type). The network identification information may be used to instruct acquiring terminal capabilities corresponding to the network indicated by the terminal in the network identification information (for example, specifying a complete terminal capability corresponding to the network).

In this embodiment, the terminal capability identification information may be included in the terminal capability query message.

另一种实施方式中，可以通过获取终端能力标识对应的终端能力的指示信息执行终端能力获取的相关操作，比如获取终端能力标识对应的终端能力。例如，第二通信设备为RAN网元。RAN网元可以根据一个指示信息向终端请求终端能力，其中，所述指示信息用于向终端请求当前终端能力标识映射的终端能力集。终端根据所述指示信息，可以向RAN网元返回当前终端能力标识映射的终端能力集。另外，上述指示信息可以是1bit指示信息，当然，对此不作限定。该实施方式中，可以在终端能力查询消息中包含获取终端能力标识对应的终端能力的指示信息。In another implementation manner, related operations of acquiring terminal capabilities may be performed by acquiring terminal capability indication information corresponding to the terminal capability identifier, such as acquiring terminal capabilities corresponding to the terminal capability identifier. For example, the second communication device is a RAN network element. The RAN network element may request the terminal capability from the terminal according to an instruction information, where the instruction information is used to request the terminal for the terminal capability set mapped by the current terminal capability identity. According to the instruction information, the terminal may return the terminal capability set mapped to the current terminal capability identifier to the RAN network element. In addition, the above-mentioned instruction information may be 1-bit instruction information, of course, it is not limited thereto.

The information indicating whether the capability signaling optimization is supported may indicate at least one of the following: the terminal has the capability signaling optimization capability, the network has the capability signaling optimization capability, and both the terminal and the network have the capability signaling optimization capability.

When the capability signaling optimization support information indicates support, when receiving a capability acquisition request (such as an RRC message for UE capability query) sent by the network, the terminal can skip or ignore the capability request filtering parameters and return the current terminal capability identifier to the network. Mapped terminal capability set or complete capability set. For example, the second communication device is a RAN network element. The RAN network element can send (for example, broadcast in system information, send in RRC message 5 or send in UE capability query message) the capability signaling optimization information to the terminal. When the capability signaling optimization support information indicates support, when receiving a capability acquisition request (such as an RRC message for UE capability query) sent by the network, the terminal can ignore the capability request filtering parameters and return the terminal capability of the current terminal capability identification mapping to the network. Set, complete terminal capability set, or complete terminal capability that meets the first condition.

另一种实施方式中，可以通过能力请求筛选参数的指示信息获取终端能力。例如：第二通信设备为RAN网元或CN网元。第二通信设备向终端发送能力请求筛选参数的指示信息。终端根据能力请求筛选参数的指示信息跳过或忽略能力请求筛选参数，向网络返回完整的终端能力。In another implementation manner, the capability of the terminal may be acquired through indication information of the capability request screening parameter. For example, the second communication device is a RAN network element or a CN network element. The second communication device sends indication information of the capability request screening parameter to the terminal. The terminal skips or ignores the capability request filtering parameter according to the indication information of the capability request filtering parameter, and returns the complete terminal capability to the network.

另一种实施方式中，可以通过跳过或忽略的能力请求筛选参数执行终端能力获取的相关操作。例如：第二通信设备为RAN网元。RAN网元向终端指示跳过或忽略的能力请求筛选参数。终端根据指示的跳过或忽略的能力请求筛选参数跳过或忽略能力请求筛选参数，向网络返回完整的终端能力或满足一定条件的终端能力。所述一定条件可以是未指示跳过或忽略的能力请求筛选参数。In another implementation manner, the related operations of acquiring the terminal's capabilities can be performed through the skipped or ignored capability request screening parameters. For example: the second communication device is a RAN network element. The RAN network element instructs the terminal to skip or ignore the capability request screening parameters. According to the indicated skip or ignore capability request filtering parameters, the terminal skips or ignores capability request screening parameters, and returns the complete terminal capability or terminal capability that meets certain conditions to the network. The certain condition may be a capability request screening parameter that does not indicate skip or ignore.

另一种实施方式中，可以通过指示第一条件执行终端能力获取的相关操作，比如获取满足第一条件的终端能力。第一条件可以包括至少以下至少一项：网络运营主体的信息、网络的标识信息、网络类型信息。网络类型信息可以包含以下至少一项：无线接入技术类型(RAT type)信息、无线接入网类型(RAN Type)信息、通信网络类型信息、网络年代信息(如5G，4G，3G，2G)、频带信息。具体地，无线接入技术类型信息、无线接入网类型信息、通信网络类型信息和网络年代信息如前文所述，此处不再赘述。所述网络类型信息可以用于指示获取在终端在所述网络类型对应的终端能力(比如指定网络类型对应的完整的终端能力)。所述网络标识信息可以用于指示获取在终端在所述网络标识信息指示的网络对应的终端能力(比如指定网络对应的完整的终端能力)。所述网络运营主体信息可以用于指示获取终端在所述网络运营主体下所有网络对应的终端能力(比如指定网络运营主体下所有网络对应的完整的终端能力)。在本实施方式中，满足第一条件的终端能力可以是满足第一条件的完整的终端能力或者是终端能力标识映射的终端能力中满足第一条件的终端能力。另一种实施方式中，可以通过指示回退频带是否上报指示信息执行终端能力获取的相关操作。终端可以根据回退频带是否上报指示信息决定是否上报回退频带对应的终端能力。比如支持的载波聚合(Carrier Aggregation)频带组合和非载波聚合的频带。In another implementation manner, related operations of acquiring terminal capabilities may be performed by instructing the first condition, such as acquiring terminal capabilities that meet the first condition. The first condition may include at least one of the following: information of a network operation subject, network identification information, and network type information. The network type information may include at least one of the following: radio access technology type (RAT) type information, radio access network type (RAN type) information, communication network type information, network age information (such as 5G, 4G, 3G, 2G) , Frequency band information. Specifically, the radio access technology type information, the radio access network type information, the communication network type information, and the network age information are as described above, and are not repeated here. The network type information may be used to instruct acquiring terminal capabilities corresponding to the network type at the terminal (for example, complete terminal capabilities corresponding to the specified network type). The network identification information may be used to instruct acquiring terminal capabilities corresponding to the network indicated by the terminal in the network identification information (for example, specifying a complete terminal capability corresponding to the network). The network operation subject information may be used to instruct acquiring terminal capabilities corresponding to all networks of the terminal under the network operation subject (such as designating complete terminal capabilities corresponding to all networks under the network operation subject). In this embodiment, the terminal capability that satisfies the first condition may be a complete terminal capability that satisfies the first condition or a terminal capability that satisfies the first condition among the terminal capabilities of the terminal capability identity mapping. In another implementation manner, related operations of acquiring the capability of the terminal may be performed by indicating whether the back-off frequency band reports the indication information. The terminal may decide whether to report the terminal capability corresponding to the fallback frequency band according to the indication information of whether the fallback frequency band is reported. For example, supported carrier aggregation (Carrier Aggregation) band combination and non-carrier aggregation band.

双连接能力缩减信息；Dual connectivity capability reduces information;

请求频带的信息；Information on requested frequency bands;

请求的MR-DC的频带的信息；Information of the requested MR-DC frequency band;

请求网络类型信息。Request network type information.

进一步地，上述频带组合能力缩减信息可以是从终端支持的频带组合能力中缩减部分频带组合能力，而上述载波聚合能力缩减信息从终端支持的载波聚合能力中缩减部分载波聚合能力，而上述双连接能力缩减信息从终端支持的双连接能力中缩减部分连接能力。Further, the above-mentioned frequency band combination capability reduction information may be a reduction of some band combination capabilities from the frequency band combination capabilities supported by the terminal, and the carrier aggregation capability reduction information reduces some carrier aggregation capabilities from the carrier aggregation capability supported by the terminal, and the dual connectivity The capability reduction information reduces part of the connection capability from the dual connectivity capability supported by the terminal.

进一步地，上述请求跳过回退频带组合的指示信息(比如request Skip Fallback Comb，request skip fallback band combination)可以用于指示终端在能力信令中跳过回退频带组合。回退频带组合可以是终端默认支持的频带组合。为了减少能力上报的开销，在所述指示信息为真时，终端可以不发送回退频带组合。但是，如果回退频带上支持的多输入多输出(Multiple-Input Multiple-Output，MIMO)数量不同，则也需要上报。Further, the above indication information (for example, Skip Fallback Comb, request fallback band combination) requesting to skip the fallback band combination may be used to instruct the terminal to skip the fallback band combination in the capability signaling. The fallback frequency band combination may be a frequency band combination supported by the terminal by default. In order to reduce the overhead of capability reporting, when the indication information is true, the terminal may not send backband combination. However, if the number of Multiple-Input Multiple-Output (MIMO) supported on the back-off frequency band is different, it also needs to be reported.

一种实施方式中，为了获取完整的终端能力，所述设置能力请求筛选参数包括至少以下一项：In an implementation manner, in order to obtain complete terminal capabilities, the set capability request screening parameter includes at least one of the following:

不包含请求跳过回退频带组合的指示信息；It does not contain instructions for requesting to skip the back-off band combination;

将是否请求跳过回退频带组合的指示信息设置为假或否；Set the indication of whether to request the skip backband combination to false or no;

发送回退频带是否上报指示信息。比如指示回退频带上支持的MIMO数量不同时上报回退频带组合。Sends indication information about whether the back-off frequency band is reported. For example, it indicates that the number of MIMO supported on the back-off frequency band is different from the back-off frequency band combination.

不难理解，当支持的MIMO数量相同时，即使回退频带组合没有上报，网络也能推导出终端支持的回退频带组合。当支持的MIMO数量不同时，根据回退频带上报指示信息，终端上报回退频带组合，网络也能知道终端的完整能力。It is not difficult to understand that when the number of supported MIMO is the same, even if the back-off frequency band combination is not reported, the network can deduce the back-off frequency band combination supported by the terminal. When the number of MIMO supported is different, according to the back-off band reporting instruction information, the terminal reports the back-off band combination, and the network can also know the complete capabilities of the terminal.

进一步地，请求差分回退频带组合的信息(如request Diff Fallback Comb List)可以用于终端排除终端支持的且与指示的频带组合相同的回退频带组合Further, the information (such as request, Diff, Fallback, and CombList) for requesting a differential backband combination can be used by the terminal to exclude the backband combination supported by the terminal and the same as the indicated band combination.

The maximum number of carrier units supported by a terminal varies. However, the network (such as a base station) may only support the simultaneous configuration of up to M CCs for the terminal. In order to reduce the overhead of capability reporting, when the maximum number of uplink carrier units requested by the network is N, even if the terminal has the capability of more than N CCs, the terminal only refers to the capability of reporting the maximum number of CCs requested by the network, such as band combination .

一种实施方式中，为了获取完整的终端能力，所述设置能力请求筛选参数可以包括至少以下一项：In an implementation manner, in order to obtain complete terminal capabilities, the set capability request screening parameter may include at least one of the following:

将请求上行最大载波单元个数设置为网络运营主体的网络支持的最大载波单元个数。The maximum number of uplink carrier units requested is set to the maximum number of carrier units supported by the network of the network operation subject.

不难理解，当网络运营主体的网络中最大载波单元个数不均衡时，通过请求网络运营主体的网络支持的最大载波单元个数，可以保证终端在所述网络运营主体的网络中能力是一样的。终端的能力标识映射的终端能力集在网络运营主体的网络中是一致的。It is not difficult to understand that when the maximum number of carrier units in the network operator's network is uneven, by requesting the maximum number of carrier units supported by the network operator's network, it is possible to ensure that the terminal has the same capability in the network of the network operator of. The terminal capability set of the terminal capability identification mapping is consistent in the network of the network operation subject.

进一步地，请求下行最大载波单元个数可以用于指示提供所述下行最大载波单元个数下的能力，比如支持的CA频带组合和非CA频带。终端支持的载波单元的最大数量多种多样。但网络(如基站)可能只能支持为终端同时配置下行最多M个CC。为了减少能力上报的开销，当网络请求上行最大载波单元个数为N时，即使终端具有多于N个CC的能力，但终端只指上报网络请求的最大CC个数下的能力，比如频带组合。Further, the requested maximum number of downlink carrier units may be used to indicate the capability under the maximum number of downlink carrier units provided, such as supported CA band combinations and non-CA bands. The maximum number of carrier units supported by a terminal varies. However, the network (such as a base station) may only support the simultaneous configuration of a maximum of M CCs for the terminal. In order to reduce the overhead of capability reporting, when the maximum number of uplink carrier units requested by the network is N, even if the terminal has the capability of more than N CCs, the terminal only refers to the capability of reporting the maximum number of CCs requested by the network, such as band combination .

将请求下行最大载波单元个数设置为网络运营主体的网络支持的最大载波单元个数。The maximum number of downlink carrier units requested is set to the maximum number of carrier units supported by the network of the network operation subject.

进一步地，请求缩减非连续频带组合的指示信息(比如request Reduced IntNon Cont Comb)可以用于缩减非连续频带组合的上报。Further, the indication information for requesting the reduction of the non-continuous frequency band combination (such as request Reduced IntNonContComb) can be used to report the reduction of the non-continuous frequency band combination.

不包含请求缩减非连续频带组合的指示信息；Does not contain instructions for requesting reduction of non-contiguous band combinations;

将是否请求缩减非连续频带组合的指示信息设置为假或否。The indication of whether to request the reduction of the discontinuous band combination is set to false or no.

请求的频带信息包含网络运营主体的网络支持的所有的频带信息；The requested frequency band information includes all frequency band information supported by the network of the network operation subject;

不难理解，不同网络运营主体的网络中支持的频带可以是不同的，通过请求网络运营主体的网络支持的所有频带信息，可以保证终端在所述网络运营主体的网络中能力是一样的。终端的能力标识映射的终端能力集在网络运营主体的网络中是一致的。It is not difficult to understand that the frequency bands supported in the networks of different network operation entities may be different. By requesting all the frequency band information supported by the network operation entity's network, it is possible to ensure that the terminals have the same capabilities in the network of the network operation entity. The terminal capability set of the terminal capability identification mapping is consistent in the network of the network operation subject.

进一步地，请求的网络类型可以括以下之一：无线接入技术类型(RAT type)、无线接入网类型(RAN Type)、通信网络类型、网络年代信息(如5G，4G，3G，2G)。所述请求的网络类型可以用于指示获取在终端在所述网络类型下的支持的能力。Further, the requested network type may include one of the following: radio access technology type (RAT type), radio access network type (RAN type), communication network type, network age information (such as 5G, 4G, 3G, 2G) .

By requesting all network types supported by the network operation entity's network, it is possible to ensure that the terminal has the same capability in the network of the network operation entity. The terminal capability set of the terminal capability identification mapping is consistent in the network of the network operation subject.

After receiving the complete capability set of the terminal sent by the RAN network element, the CN network element can establish a mapping relationship between the terminal capability identifier and the complete capability set. In this implementation manner, the CN network element can instruct the RAN network element to obtain the complete capability set of the terminal.

For example, the third communication device is a RAN network element. When the RAN network element obtains the terminal capability identification information of the terminal but the terminal capability identification information has no mapped terminal capability or when the RAN network element obtains information on the terminal support capability signaling optimization, the RAN network element may request the terminal from the terminal according to the terminal capability identification information ability.
