Such information may be, for example, slice-related information, public land mobile network (Public Land Mobile Network, PLMN) selection-related information, and terminal policy-related information.
然而,在一些场景中,由于一些原因,核心网设备和终端之间的信息交互可能失败。比如,当终端的蜂窝链路信号质量不好时,蜂窝链路可能异常释放,因此,通过蜂窝链路传递的信息不能送达接收方,通信失败。However, in some scenarios, due to some reasons, the information exchange between the core network device and the terminal may fail. For example, when the signal quality of the cellular link of the terminal is not good, the cellular link may be released abnormally. Therefore, the information transmitted through the cellular link cannot be delivered to the receiver, and the communication fails.

首先,以图5所示的通信系统应用于如图1-图4所示的网络架构为例,如图7所示,本申请实施例提供的通信方法,包括如下步骤:First, taking the communication system shown in FIG. 5 applied to the network architecture shown in FIG. 1 to FIG. 4 as an example, as shown in FIG. 7 , the communication method provided by the embodiment of the present application includes the following steps:
S101、第一设备通过第一接入向第二设备发送第一NAS消息。S101. A first device sends a first NAS message to a second device through a first access.
作为一种可能的实现方式,第一设备通过第一接入的协议实体(或称实例)发送第一NAS消息。其中,第一设备可以包括多个协议实体(或称实例),每个协议实体对应一种接入类型。As a possible implementation manner, the first device sends the first NAS message through the first accessed protocol entity (or called an instance). The first device may include multiple protocol entities (or instances), and each protocol entity corresponds to an access type.
其中,第一接入是3GPP接入或非3GPP接入。Wherein, the first access is 3GPP access or non-3GPP access.
当第一接入是3GPP接入,第一设备可以通过3GPP接入设备(比如基站)与第二设备交互。当第一接入是非3GPP接入,第一设备可以通过非3GPP接入设备(比如N3IWF)与第二设备交互。When the first access is a 3GPP access, the first device may interact with the second device through a 3GPP access device (such as a base station). When the first access is a non-3GPP access, the first device may interact with the second device through a non-3GPP access device (such as N3IWF).
第一NAS消息可以包括与接入类型有关的信息单元(information element,IE),和/或包括与接入类型无关的IE。接入类型是3GPP接入或非3GPP接入。即,第一NAS消息可以包括与接入类型有关的IE,也可以包括与接入类型无关的IE,还可以既包括与接入类型有关的IE,又包括与接入类型无关的IE。The first NAS message may include an information element (IE) related to the access type, and/or include an IE that is not related to the access type. The access type is 3GPP access or non-3GPP access. That is, the first NAS message may include an IE related to the access type, or an IE that is not related to the access type, and may also include both an IE related to the access type and an IE that is not related to the access type.
与接入类型是否相关,主要针对IE的接收方的处理方式来加以区分。与接入类型无关的IE,通常无需接收方按照特定接入类型对应的方式来处理,具体的,可以是任意接入类型对应的协议实体(或实例)来处理。对接收方来说,当收到与接入类型无关的IE,其可以通过接收该NAS消息的接入类型(比如3GPP接入)对应的协议实体(或实例)处理该IE。比如,接收方(比如终端设备)通过3GPP接入接收与接入类型无关的IE,并通过3GPP接入对应的协议实体或实例处理该与接入类型无关的IE;而当该接收方通过非3GPP接入接收该与接入类型无关的IE,则通过非3GPP接入对应的协议实体或实例处理该与接入类型无关的IE。示例性的,接入类型无关的IE包括但不限于漫游操作(steering of roaming,SOR)、终端参数更新(UE parameter update)、终端策略容器(UE policy container)。Whether it is related to the access type is mainly distinguished according to the processing method of the receiver of the IE. The IE that is not related to the access type generally does not need to be processed by the receiver in a manner corresponding to a specific access type, and specifically, it may be processed by a protocol entity (or instance) corresponding to any access type. For the receiver, when receiving the IE irrelevant to the access type, it can process the IE through the protocol entity (or instance) corresponding to the access type (such as 3GPP access) in which the NAS message is received. For example, the receiver (such as a terminal device) receives IEs that are not related to access types through 3GPP access, and processes the IEs that are not related to access types through 3GPP access to the corresponding protocol entity or instance; When the 3GPP access receives the IE that is not related to the access type, the protocol entity or instance corresponding to the non-3GPP access processes the IE that is not related to the access type. Exemplarily, the access type-independent IE includes, but is not limited to, roaming operation (steering of roaming, SOR), terminal parameter update (UE parameter update), and terminal policy container (UE policy container).
与接入类型有关的IE,通常是指需要目标接入类型的协议实体(或实例)来处理。接收方接收到与接入类型有关的IE后,接收该IE的接入类型的协议实体可能无法处理该IE,那么,接收方通常需要将该IE传递给目标接入类型的协议实体(或实例)来处理。比如,接收方通过3GPP接入接收与接入类型有关的IE,该IE携带用于指示目标接入类型(比如非3GPP接入)的指示信息,那么,接收方需要通过非3GPP接入对应的协议实体或实例处理该IE。接入类型相关的IE,比如但不限于是Allowed/Rejected NSSAI、跟踪区域标识列表(tracking area identity list,TAI list)、终端无线能力标识(UE Radio Capability ID)。The IE related to the access type usually refers to the protocol entity (or instance) that needs the target access type to process. After the receiver receives the IE related to the access type, the protocol entity receiving the access type of the IE may not be able to process the IE, so the receiver usually needs to pass the IE to the protocol entity (or instance) of the target access type. ) to process. For example, the receiver receives an IE related to the access type through 3GPP access, and the IE carries indication information used to indicate the target access type (such as non-3GPP access), then the receiver needs to access the corresponding IE through non-3GPP access. The protocol entity or instance handles the IE. IE related to the access type, such as but not limited to Allowed/Rejected NSSAI, tracking area identity list (tracking area identity list, TAI list), terminal radio capability identifier (UE Radio Capability ID).
示例性的,网络切片鉴权和认证(network slice-specific authentication and authorization,NSSAA)包括一个或多个与接入类型有关的IE,配置更新命令(configuration update command,CUC)包括一个或多个与接入类型有关的IE,比如,TAI list。Exemplarily, the network slice-specific authentication and authorization (NSSAA) includes one or more IEs related to the access type, and the configuration update command (CUC) includes one or more IEs related to the access type. IE related to the access type, for example, TAI list.
需要说明的是,对于同一类型IE来说,当其包括在不同消息中,对其处理的方式可能不同。比如,对于3GPP接入对应的某类IE1,当IE1包括在NAS消息1中,在另一些使用场景下,IE1包括在NAS消息2中。第一设备向第二设备发送消息1,第二设备可以将NAS消息1中的IE1交由3GPP接入对应的协议实体处理。在另一些使用场景下,第一设备向第二设备发送NAS消息2,第二设备可以将NAS消息2中的IE1也交由IE1对应的3GPP接入的协议实体处理。其中,3GPP接入对应的协议实体对NAS消息1中的IE1和NAS消息2中的IE1的处理方式可以相同,也可以不同,具体处理方式与NAS消息1的类型和NAS消息2的类型相关。It should be noted that, for the same type of IE, when it is included in different messages, the processing methods may be different. For example, for a certain type of IE1 corresponding to 3GPP access, when IE1 is included in NAS message 1, in other usage scenarios, IE1 is included in NAS message 2. The first device sends message 1 to the second device, and the second device may hand over IE1 in the NAS message 1 to a protocol entity corresponding to 3GPP access for processing. In other usage scenarios, the first device sends the NAS message 2 to the second device, and the second device may also hand over the IE1 in the NAS message 2 to the 3GPP access protocol entity corresponding to the IE1 for processing. The protocol entity corresponding to 3GPP access may process IE1 in NAS message 1 and IE1 in NAS message 2 in the same or different manner, and the specific processing manner is related to the type of NAS message 1 and the type of NAS message 2 .
S102、若第一NAS消息在第一接入上发送失败,则第一设备通过第二接入向第二设备发送第二NAS消息。其中,第二NAS消息与第一NAS消息关联。S102. If the first NAS message fails to be sent on the first access, the first device sends the second NAS message to the second device through the second access. Wherein, the second NAS message is associated with the first NAS message.
相应的,第二设备通过第二接入从第一设备接收第二NAS消息。Correspondingly, the second device receives the second NAS message from the first device through the second access.
第二NAS消息包括第一指示信息,第一指示信息具体可以包括在第二NAS消息的IE中,也可以在第一NAS消息的基础上新增IE,该新增IE包括第一指示信息。The second NAS message includes first indication information, and the first indication information may be specifically included in the IE of the second NAS message, or an IE may be added based on the first NAS message, and the newly added IE includes the first indication information.
以第二NAS消息包括第一IE,第一IE包括第一指示信息为例,第一指示信息用于指示第一IE的目标接入类型,目标接入类型包括3GPP接入或非3GPP接入。如下表1示出了第二NAS消息中第一IE的一种可能的结构。Taking the second NAS message including the first IE and the first IE including the first indication information as an example, the first indication information is used to indicate the target access type of the first IE, and the target access type includes 3GPP access or non-3GPP access . Table 1 below shows a possible structure of the first IE in the second NAS message.
表1 第二NAS消息的第一IETable 1 The first IE of the second NAS message
如上表1所示,Access type IEI,即上述第一IE的标识(information-element identifier,IEI),0spare即保留字段(或称空闲字段等),Access type即第一指示信息。As shown in Table 1 above, Access type IEI is the identifier (information-element identifier, IEI) of the above-mentioned first IE, 0spare is the reserved field (or idle field, etc.), and Access type is the first indication information.
其中,第一IE的标识用于唯一标识该第一IE。示例性的,第一IE的标识占4比特。The identifier of the first IE is used to uniquely identify the first IE. Exemplarily, the identifier of the first IE occupies 4 bits.
第一指示信息用于指示第一IE的目标接入类型。如此,当接收方接收到第二NAS消息,并解析出第二指示信息后,可以按照对从目标接入类型接收的IE的处理方式处理该第一IE。换句话说,接收方收到第一IE之后,在处理该第一IE时,视为该第一IE是从第一指示信息所指示的目标接入类型收到(the UE shall to handle the IE as if the IE was received from the access type same as the"Destination access type"indicated)。也就意味着,接收方通过目标接入类型对应的协议实体(或实例instance)处理该第一IE。比如,接收方接收到第二NAS消息,该第二NAS消息包括第一IE,第一IE的第一指示信息指示目标接入类型是3GPP接入,则接收方通过3GPP接入对应的协议实体(或实例)处理该第一IE。The first indication information is used to indicate the target access type of the first IE. In this way, when the receiver receives the second NAS message and parses out the second indication information, it can process the first IE according to the processing method for the IE received from the target access type. In other words, after the receiver receives the first IE, when processing the first IE, it is deemed that the first IE is received from the target access type indicated by the first indication information (the UE shall handle the IE as if the IE was received from the access type same as the "Destination access type" indicated). That is to say, the receiver processes the first IE through the protocol entity (or instance) corresponding to the target access type. For example, if the receiver receives a second NAS message, the second NAS message includes the first IE, and the first indication information of the first IE indicates that the target access type is 3GPP access, then the receiver accesses the corresponding protocol entity through 3GPP (or instance) process the first IE.
需要说明的是,第一IE中第一IE的标识,保留字段,目标接入类型各自占的比特数,以各自在字节中所占位置可以如表1所示,也可以另行设置,本申请实施例对此不限制。It should be noted that the number of bits occupied by the identifier of the first IE, the reserved field, and the target access type in the first IE may be as shown in Table 1, or may be set separately. The application embodiments do not limit this.
以第一指示信息占2比特为例,下表2-1示出了第一指示信息的示例。Taking the first indication information occupying 2 bits as an example, Table 2-1 below shows an example of the first indication information.
表2-1 第一指示信息Table 2-1 The first indication information
0101 | 表示3GPP接入Indicates 3GPP access |
1010 | 表示非3GPP接入Indicates non-3GPP access |
当然,具体使用何数值表示3GPP接入,以及何数值表示非3GPP接入,可以灵活设置,本申请实施例不对此进行限制。比如,表2-2为另一种可能的第一指示信息。再比如,000也可表示非3GPP接入,001表示3GPP接入。或,用其他数值表示非3GPP接入以及非3GPP接入。Of course, what value is specifically used to represent 3GPP access, and what value is used to represent non-3GPP access can be flexibly set, which is not limited in this embodiment of the present application. For example, Table 2-2 is another possible first indication information. For another example, 000 may also represent non-3GPP access, and 001 may represent 3GPP access. Or, use other numerical values to represent non-3GPP access and non-3GPP access.
表2-2 第一指示信息Table 2-2 The first indication information
000000 |
表示3GPP接入Indicates |
001001 | 表示非3GPP接入Indicates non-3GPP access |
需要说明的是,第二NAS消息可能包括一个或多个IE。不同IE对应的目标接入类型可能不同或相同。如下表3示出第二NAS消息包括多个IE的情况。It should be noted that the second NAS message may include one or more IEs. The target access types corresponding to different IEs may be different or the same. Table 3 below shows the case where the second NAS message includes multiple IEs.
表3 第二NAS消息Table 3 Second NAS message
IEIIEI | Information ElementInformation Element | 第一指示信息first instruction information |
3131 | Configured NSSAI(配置的网络切片选择辅助信息)Configured NSSAI (configured network slice selection auxiliary information) | 缺省default |
1111 | Rejected NSSAI(不允许的网络切片选择辅助信息)Rejected NSSAI (Disallowed Network Slice Selection Auxiliary Information) | 0101 |
6767 | UE radio capability ID(无线能力标识)UE radio capability ID (radio capability identification) | 缺省default |
4444 | 5GS registration result(注册结果)5GS registration result (registration result) | 缺省default |
其中,表3中的Rejected NSSAI,即包括第一指示信息的IE(比如上述表1所示第一IE)。Among them, the Rejected NSSAI in Table 3 is an IE including the first indication information (such as the first IE shown in Table 1 above).
其中,表3中不同IE可以对应不同或相同目标接入类型。这样一来,第二NAS消息的接收方对不同IE可以有不同处理方式。具体的,对目标接入类型是3GPP接入的IE,接收方通过3GPP接入对应的协议实体(或实例)处理该类IE。对目标接入类型是非3GPP接入的IE,接收方通过非3GPP接入对应的协议实体处理该类IE。Wherein, different IEs in Table 3 may correspond to different or the same target access type. In this way, the receiver of the second NAS message can handle different IEs in different ways. Specifically, for an IE whose target access type is 3GPP access, the receiver processes this type of IE through a corresponding protocol entity (or instance) of 3GPP access. For an IE whose target access type is non-3GPP access, the receiver processes this type of IE through a protocol entity corresponding to the non-3GPP access.
再比如,NAS消息为TRANSPROT消息,可以在该消息的payload container这一IE中携带第一指示信息,并增加指示payload container type。For another example, if the NAS message is a TRANSPROT message, the first indication information can be carried in the IE of the payload container of the message, and the indication payload container type can be added.
上述介绍了第一指示信息可以包括在第二NAS消息的IE中,在另一些实施例中,也可以在第一NAS消息的基础上新增IE,该新增IE包括第一指示信息,以得到第二NAS消息。这种情况下,第一指示信息用于指示第二NAS消息的目标接入类型。如此,第二设备接收到该第二NAS消息后,按照从目标接入类型接收的NAS消息的处理方式处理第二NAS消息。当接收方接收到包括第一指示信息的第二NAS消息,通过第一指示信息指示的目标接入类型(比如3GPP接入)对应的协议实体(或实例)处理该第二NAS消息。It is described above that the first indication information may be included in the IE of the second NAS message. In other embodiments, an IE may also be added on the basis of the first NAS message, and the newly added IE includes the first indication information to Get the second NAS message. In this case, the first indication information is used to indicate the target access type of the second NAS message. In this way, after receiving the second NAS message, the second device processes the second NAS message according to the processing method of the NAS message received from the target access type. When the receiver receives the second NAS message including the first indication information, the second NAS message is processed by a protocol entity (or instance) corresponding to the target access type (such as 3GPP access) indicated by the first indication information.

XX | 第一指示信息first instruction information |
示例性的,如上述表4的第一指示信息用于指示整个第二NAS消息的目标接入类型。Exemplarily, the first indication information in Table 4 above is used to indicate the target access type of the entire second NAS message.
上述实施例的第一指示信息可以理解为用于间接指示第二设备根据第一接入对应的方式处理第二NAS消息。即第一指示信息用于指示第一接入的类型(比如表4所示的第一指示信息)。这样,第二设备接收第一指示信息后,可获知第一接入的类型,并根据第一接入对应的方式处理第二NAS消息。The first indication information in the foregoing embodiment may be understood as being used to indirectly instruct the second device to process the second NAS message according to the mode corresponding to the first access. That is, the first indication information is used to indicate the type of the first access (for example, the first indication information shown in Table 4). In this way, after receiving the first indication information, the second device can know the type of the first access, and process the second NAS message according to the mode corresponding to the first access.
在另一些实施例中,第一指示信息用于指示不根据当前接入对应的方式处理该第二NAS消息。第二设备通过第二接入接收第二NAS消息(包括第一指示信息)后,不根据当前接入(即第二接入)对应的方式处理第二NAS消息,而采用另一种接入(即第一接入)对应的方式处理第二NAS消息。其中,当前接入,指的是第二设备接收第二NAS消息的接入。In other embodiments, the first indication information is used to indicate that the second NAS message is not processed according to the mode corresponding to the current access. After receiving the second NAS message (including the first indication information) through the second access, the second device does not process the second NAS message according to the mode corresponding to the current access (ie, the second access), but uses another access (ie, the first access) to process the second NAS message in a corresponding manner. Wherein, the current access refers to the access in which the second device receives the second NAS message.
比如,第二接入为3GPP,第一指示信息用于指示第二设备不根据3GPP接入对应的方式处理第二NAS消息。从而,第二设备通过第二接入接收第一指示信息后,不根据3GPP接入对应的方式处理第二NAS消息,而是根据非3GPP接入对应的方式处理第二NAS消息。For example, the second access is 3GPP, and the first indication information is used to instruct the second device not to process the second NAS message according to the mode corresponding to the 3GPP access. Therefore, after receiving the first indication information through the second access, the second device does not process the second NAS message according to the mode corresponding to the 3GPP access, but processes the second NAS message according to the mode corresponding to the non-3GPP access.
在另一些实施例中,第一指示信息用于指示第二接入的类型。第二设备通过第二接入接收第一指示信息后,不根据第一指示信息指示的第二接入对应的方式处理第二NAS消息,而采用第一接入对应的方式处理第二NAS消息。In other embodiments, the first indication information is used to indicate the type of the second access. After receiving the first indication information through the second access, the second device does not process the second NAS message according to the mode corresponding to the second access indicated by the first indication information, but processes the second NAS message in the mode corresponding to the first access .
在另一些实施例中,第一指示信息用于直接指示根据第一接入对应的方式处理第二NAS消息,即第二设备通过第二接入接收第一指示信息后,获知根据第一接入对应的方式处理第二NAS消息。In other embodiments, the first indication information is used to directly instruct to process the second NAS message according to the mode corresponding to the first access, that is, after receiving the first indication information through the second access, the second device learns that the second NAS message is processed according to the first access method. The second NAS message is processed in a corresponding manner.
在另一些实施例中,第一指示信息具体还可以是NAS连接标识(NAS connection identifier)。该标识用于标识NAS连接是3GPP连接或非3GPP连接。或,NAS连接标识包括在第一指示信息中。In other embodiments, the first indication information may specifically be a NAS connection identifier (NAS connection identifier). The identifier is used to identify whether the NAS connection is a 3GPP connection or a non-3GPP connection. Or, the NAS connection identifier is included in the first indication information.
作为一种可能的实现方式,第一设备通过第二接入对应的协议实体(或称实例)向第二设备发送第二NAS消息。第二设备通过第二接入对应的协议实体(或称实例)从第一设备接收第二NAS消息。As a possible implementation manner, the first device sends the second NAS message to the second device through a protocol entity (or called an instance) corresponding to the second access. The second device receives the second NAS message from the first device through a protocol entity (or called an instance) corresponding to the second access.
可以理解,在一些场景中,第一NAS消息可能在第一接入上发送失败。比如,以第一接入为3GPP接入为例,某些情况下,3GPP网络(比如蜂窝网)可能异常,网络异常可以是断网,也可以是网络的信号质量不好,或其他情况。网络异常情况下,AMF和终端设备之间的链路可能被释放,导致AMF和终端设备之间无法通过3GPP接入传递第一NAS消息。It can be understood that, in some scenarios, the first NAS message may fail to be sent on the first access. For example, taking the first access as 3GPP access as an example, in some cases, a 3GPP network (such as a cellular network) may be abnormal. In the case of network abnormality, the link between the AMF and the terminal device may be released, so that the first NAS message cannot be transmitted between the AMF and the terminal device through 3GPP access.
本申请实施例中,当第一NAS消息在第一接入上发送失败,考虑第一设备在第二接入上向第二设备发送与第一NAS消息关联的第二NAS消息。其中,第二接入的接入类型与第一接入不同。具体的,第一接入是3GPP接入的情况下,第二接入是非3GPP接入。或,第一接入是非3GPP接入的情况下,第二接入是3GPP接入。这就意味着,第一设备和第二设备能够在第二接入上传输与第一接入(与第二接入是不同接入类型)对应的第二NAS消息。In this embodiment of the present application, when the first NAS message fails to be sent on the first access, it is considered that the first device sends the second NAS message associated with the first NAS message to the second device on the second access. Wherein, the access type of the second access is different from that of the first access. Specifically, when the first access is a 3GPP access, the second access is a non-3GPP access. Or, when the first access is a non-3GPP access, the second access is a 3GPP access. This means that the first device and the second device can transmit on the second access a second NAS message corresponding to the first access (which is of a different access type from the second access).
作为一种可能的设计,第一NAS消息可以是现有技术中的NAS消息,第二NAS消息是在第一NAS消息的基础上封装进第一指示信息得到的NAS消息。具体的,第二NAS消息包括第一指示信息,第一指示信息用于指示根据第一接入对应的方式处理第二NAS消息。比如,如下表5、表6示出了第一NAS消息、第二NAS消息的一种可能的示例。As a possible design, the first NAS message may be a NAS message in the prior art, and the second NAS message is a NAS message obtained by encapsulating the first indication information on the basis of the first NAS message. Specifically, the second NAS message includes first indication information, where the first indication information is used to instruct to process the second NAS message according to the mode corresponding to the first access. For example, the following Tables 5 and 6 show a possible example of the first NAS message and the second NAS message.

表6 第二NAS消息Table 6 Second NAS message
可以看出,表5所示第一NAS消息不包括第一指示信息,表6所示第二NAS消息在第一NAS消息的基础上封装进第一指示信息,且该第一指示信息可以封装在第一NAS消息的信息单元(比如信息单元Configured NSSAI)中。也就是,在表5所示第一NAS消息的信息单元Configured NSSAI中封装进第一指示信息000,即得到表6所示第二NAS消息。It can be seen that the first NAS message shown in Table 5 does not include the first indication information, and the second NAS message shown in Table 6 is encapsulated into the first indication information on the basis of the first NAS message, and the first indication information can be encapsulated In the information element (such as the information element Configured NSSAI) of the first NAS message. That is, the first indication information 000 is encapsulated in the information element Configured NSSAI of the first NAS message shown in Table 5, that is, the second NAS message shown in Table 6 is obtained.
对于通过第二接入接收的第一指示信息缺省的IE,比如表6所示信息单元5GS registration result,第二设备按照现有技术的流程处理该信息单元,即根据接收该信息单元的接入(即第二接入)对应的方式处理该信息单元。For the default IE of the first indication information received through the second access, such as the information unit 5GS registration result shown in Table 6, the second device processes the information unit according to the process of the prior art, that is, according to the access The information unit is processed in a manner corresponding to the incoming (that is, the second access).
在另一些实施例中,也可在第一NAS消息的基础上新增IE,在新增IE中封装进第一指示信息,来得到第二NAS消息。比如在表5所示第一NAS消息的基础上新增IE X,在该新增IE X中封装进第一指示信息,得到表7所示第二NAS消息。In other embodiments, an IE may also be added on the basis of the first NAS message, and the first indication information may be encapsulated in the newly added IE to obtain the second NAS message. For example, an IEX is added on the basis of the first NAS message shown in Table 5, and the first indication information is encapsulated in the newly added IEX to obtain the second NAS message shown in Table 7.
表7 第二NAS消息Table 7 Second NAS message
[根据细则91更正 11.11.2020]
作为另一种可能的实现方式,第一NAS消息可以包括第五指示信息。第五指示信息用于指示根据第一接入对应的方式处理第一NAS消息。第一NAS消息携带第五指示信息的具体方式可以参见上述第二NAS消息携带第一指示信息的方式。这种情况下,第二NAS消息可以是与第一NAS消息是相同的NAS消息,即第一设备可以直接通过第二接入向第二设备发送第一NAS消息,即由于第一NAS消息已携带用于指示目标接入类型的指示信息,无需在第一NAS消息的基础上再封装用于指示目标接入类型的指示信息。[Correction 11.11.2020 under Rule 91]
As another possible implementation manner, the first NAS message may include fifth indication information. The fifth indication information is used to indicate that the first NAS message is processed according to the mode corresponding to the first access. For a specific manner in which the first NAS message carries the fifth indication information, reference may be made to the foregoing manner in which the second NAS message carries the first indication information. In this case, the second NAS message may be the same NAS message as the first NAS message, that is, the first device may directly send the first NAS message to the second device through the second access, that is, because the first NAS message has been Carrying the indication information for indicating the target access type, it is not necessary to re-encapsulate the indication information for indicating the target access type on the basis of the first NAS message.

S103、第二设备根据第一接入对应的方式处理第二NAS消息。S103. The second device processes the second NAS message according to the mode corresponding to the first access.
作为一种可能的实现方式,第二设备通过第二接入的协议实体(或称实例)接收到包括第一指示信息的第二NAS消息后,将第二NAS消息转给第一接入对应的协议实体(或称实例),由第一接入对应的协议实体(或称实例)处理该第二NAS消息。As a possible implementation manner, after receiving the second NAS message including the first indication information through the protocol entity (or instance) of the second access, the second device forwards the second NAS message to the corresponding first access The protocol entity (or instance) corresponding to the first access process the second NAS message.
比如,第二设备通过第二接入的协议实体接收到表6所示第二NAS消息后,第二接入对应的协议实体(或实例)将信息单元Configured NSSAI转给第一接入对应的协议实体(或实例),由第一接入对应的协议实体(或实例)处理该信息单元Configured NSSAI。For example, after the second device receives the second NAS message shown in Table 6 through the protocol entity of the second access, the protocol entity (or instance) corresponding to the second access transfers the information element Configured NSSAI to the corresponding device of the first access. Protocol entity (or instance), the information unit Configured NSSAI is processed by the protocol entity (or instance) corresponding to the first access.
再比如,第二设备通过第二接入对应的实例接收到表7所示第二NAS消息后,将第二NAS消息转给第一接入对应的协议实体(或实例),由第一接入对应的协议实体(或实例)处理该第二NAS消息。For another example, after receiving the second NAS message shown in Table 7 through the instance corresponding to the second access, the second device forwards the second NAS message to the protocol entity (or instance) corresponding to the first access, and the first access into the corresponding protocol entity (or instance) to process the second NAS message.
示例性的,参见图8,给出AMF和终端设备之间的具体交互示例。该图8介绍AMF和终端设备的内部实现。以AMF向终端设备发送NAS消息为例,AMF检测到3GPP接入方式对应的底层链路故障(lower layer failure),则通过非3GPP接入向终端设备发送NAS消息。该NAS消息包括IE1、IE2,均与接入类型有关。其中,IE1需3GPP接入对应的方式来处理,IE2需非3GPP接入对应的方式来处理。AMF在IE1中封装进第一指示信息000,用于指示终端设备根据3GPP接入对应的方式处理IE1,在IE2中封装进第一指示信息001,用于指示终端设备根据非3GPP接入对应的方式处理IE2。相应的,终端设备通过非3GPP接入对应的协议实体(或实例)接收该NAS消息。可选的,终端设备可通过非3GPP接入对应的协议实体解析该NAS消息,读取IE1的第一指示信息000,以及IE2的第一指示信息001。如此,非3GPP接入对应的协议实体获知需通过本协议实体处理IE2,并将IE1传递给3GPP接入对应的协议实体处理。Illustratively, referring to FIG. 8, a specific interaction example between the AMF and the terminal device is given. This Figure 8 describes the internal implementation of the AMF and the terminal equipment. Taking the AMF sending a NAS message to a terminal device as an example, when the AMF detects a lower layer failure corresponding to the 3GPP access mode, it sends a NAS message to the terminal device through non-3GPP access. The NAS message includes IE1 and IE2, both of which are related to the access type. Among them, IE1 needs to be processed in a way corresponding to 3GPP access, and IE2 needs to be processed in a way corresponding to non-3GPP access. AMF is encapsulated into the first indication information 000 in IE1, which is used to instruct the terminal device to process IE1 according to the mode corresponding to 3GPP access, and the first indication information 001 is encapsulated in IE2, which is used to instruct the terminal device to process IE1 according to the corresponding mode of non-3GPP access. way to handle IE2. Correspondingly, the terminal device receives the NAS message through a non-3GPP access corresponding protocol entity (or instance). Optionally, the terminal device may parse the NAS message through a protocol entity corresponding to non-3GPP access, and read the first indication information 000 of IE1 and the first indication information 001 of IE2. In this way, the protocol entity corresponding to the non-3GPP access learns that IE2 needs to be processed by this protocol entity, and transfers IE1 to the protocol entity corresponding to the 3GPP access for processing.
再例如,参见图9,AMF在3GPP接入上发送NAS消息(NAS消息包括IE1)失败,则通过非3GPP接入向终端设备发送NAS消息。该NAS消息的基础上新增IE,在该新增IE中封装进第一指示信息001,用于指示终端设备根据3GPP接入对应的方式处理该NAS消息。相应的,终端设备通过非3GPP接入对应的协议实体(或实例)接收该NAS消息,并根据第一指示信息将该NAS消息传递给3GPP接入对应的协议实体处理。For another example, referring to FIG. 9 , if the AMF fails to send the NAS message (the NAS message includes IE1) on the 3GPP access, the AMF sends the NAS message to the terminal device through the non-3GPP access. An IE is added on the basis of the NAS message, and first indication information 001 is encapsulated in the newly added IE, which is used to instruct the terminal device to process the NAS message according to a mode corresponding to 3GPP access. Correspondingly, the terminal device receives the NAS message through the protocol entity (or instance) corresponding to the non-3GPP access, and transmits the NAS message to the protocol entity corresponding to the 3GPP access for processing according to the first indication information.
可以理解,在某些场景中,第一指示信息可能被误操作。比如,第一设备可能错置第一指示信息的值或漏填第一指示信息的值,此种情况下,需设计针对误操作的处理方案。比如,在以000表示3GPP接入,以001表示非3GPP接入的情况下,第一设备可能将第二NAS消息的第一指示信息误填充为011。这种情况下,在本申请实施例中,第二设备通过当前接入对应的方式处理。当前接入即接收第二NAS消息的接入。比如,第二设备通过第二接入接收到包括第一指示信息(值为011)的第二NAS消息,并通过第二接入对应的方式处理该第二NAS消息。It can be understood that, in some scenarios, the first indication information may be mishandled. For example, the first device may misplace the value of the first indication information or omit to fill in the value of the first indication information. In this case, it is necessary to design a processing solution for the wrong operation. For example, in the case where 000 represents 3GPP access and 001 represents non-3GPP access, the first device may incorrectly fill the first indication information of the second NAS message with 011. In this case, in this embodiment of the present application, the second device handles the process in a manner corresponding to the current access. The current access is the access to receive the second NAS message. For example, the second device receives the second NAS message including the first indication information (the value is 011) through the second access, and processes the second NAS message through a manner corresponding to the second access.
需要注意的是,第一指示信息被误填充或漏填,包括两种情况。一种情况是,第一NAS消息包括第一指示信息,第一设备在填充第一NAS消息的第一指示信息时产生误填充或漏填。另一种情况是,第一NAS消息不包括第一指示信息,第一设备在第一NAS消息的基础上封装第一指示信息得到第二NAS消息时,误填充或漏填该第一 指示信息。It should be noted that the first indication information is incorrectly filled or omitted, including two cases. In one case, the first NAS message includes the first indication information, and the first device generates incorrect filling or omission when filling the first indication information of the first NAS message. In another case, the first NAS message does not include the first indication information, and when the first device encapsulates the first indication information on the basis of the first NAS message to obtain the second NAS message, the first indication information is incorrectly filled or omitted. .
在另一些实施例中,当第一NAS消息包括的IE均为与接入类型无关的IE,第二NAS消息也可以不携带第一指示信息。In other embodiments, when the IEs included in the first NAS message are all IEs irrelevant to the access type, the second NAS message may also not carry the first indication information.
S104、第二设备向第一设备发送第一响应消息。S104. The second device sends a first response message to the first device.
相应的,第一设备从第二设备接收第一响应消息。Correspondingly, the first device receives the first response message from the second device.
第一响应消息用于指示已接收第二NAS消息。The first response message is used to indicate that the second NAS message has been received.
作为一种可能的实现方式,第二设备通过第二接入向第一设备发送第一响应消息。即,第二设备的第一接入对应的协议实体(或称实例)处理完第二NAS消息后,将处理结果传递给第二接入对应的协议实体,第二接入对应的协议实体根据处理结果向第一设备发送第一响应消息。所述第一响应消息包括第二指示信息,所述第二指示信息用于指示所述第一响应消息对应于所述第一接入。如此,第一设备通过第二接入的协议实体接收到第一响应消息后,将第一响应消息传递给第一接入的协议实体处理。As a possible implementation manner, the second device sends the first response message to the first device through the second access. That is, after the protocol entity (or instance) corresponding to the first access of the second device processes the second NAS message, it transmits the processing result to the protocol entity corresponding to the second access, and the protocol entity corresponding to the second access is based on the The processing result sends a first response message to the first device. The first response message includes second indication information, where the second indication information is used to indicate that the first response message corresponds to the first access. In this way, after receiving the first response message through the second access protocol entity, the first device transfers the first response message to the first access protocol entity for processing.
或,第二设备通过第一接入的协议实体向第一设备发送第一响应消息。Or, the second device sends the first response message to the first device through the first accessed protocol entity.
步骤S104为可选步骤。Step S104 is an optional step.
与现有技术中当第一接入出现异常等情况,第一接入上的第一NAS消息发送失败,导致通信失败相比,本申请实施例提供的通信方法,当第一NAS消息在第一接入上发送失败,第一设备可以通过第二接入发送与第一NAS消息关联的第二NAS消息。也就是,第一设备仍可通过第二接入与第二设备交互与第一NAS消息关联的消息,以便第二设备通过该与第一NAS消息关联的消息获知第一NAS消息。这样一来,降低了通信失败的概率。此外,第二NAS消息包括第一指示信息,如此,能够指示第二设备根据第一接入对应的方式处理该第二NAS消息,以便第二设备获知与第二NAS消息关联的第一NAS消息。Compared with the situation in the prior art that when the first access is abnormal, the first NAS message on the first access fails to be sent, resulting in a communication failure. If the sending on the access fails, the first device may send the second NAS message associated with the first NAS message through the second access. That is, the first device can still exchange messages associated with the first NAS message with the second device through the second access, so that the second device learns the first NAS message through the message associated with the first NAS message. In this way, the probability of communication failure is reduced. In addition, the second NAS message includes the first indication information, so that the second device can be instructed to process the second NAS message according to the mode corresponding to the first access, so that the second device can learn the first NAS message associated with the second NAS message .
需要说明的是,本申请实施例提供的通信方法的前提是终端设备在第一接入和第二接入均已注册。且终端设备需在同一AMF上注册第一接入和第二接入。本申请实施例提供的注册流程中,第一设备向第二设备发送注册消息,注册消息可携带第一设备的能力信息,能力信息用于指示第一设备能够通过第二接入传输第一接入对应的NAS消息。当第一设备是终端设备,则注册消息为注册请求消息(registration request)。若第一设备是AMF,则注册消息为注册响应消息。注册响应消息包括注册接受消息(registration accept)或注册拒绝消息(registration reject)。如下具体介绍注册流程。It should be noted that the premise of the communication method provided by the embodiment of the present application is that the terminal device has been registered in both the first access and the second access. And the terminal device needs to register the first access and the second access on the same AMF. In the registration process provided in this embodiment of the present application, the first device sends a registration message to the second device. The registration message may carry capability information of the first device, and the capability information is used to indicate that the first device can transmit the first access through the second access. Enter the corresponding NAS message. When the first device is a terminal device, the registration message is a registration request message (registration request). If the first device is an AMF, the registration message is a registration response message. The registration response message includes a registration accept message (registration accept) or a registration rejection message (registration reject). The registration process is described in detail below.

Moreover, the capability information carried in the registration request message can inform the AMF that the terminal device can transmit the NAS message corresponding to the first access on the second access.
作为另一种可能的设计,该注册请求消息用于终端设备请求在第二接入上注册。 且,通过该注册请求消息携带的能力信息能够告知AMF,该终端设备能够在第二接入上传输第一接入对应的NAS消息。As another possible design, the registration request message is used for the terminal device to request to register on the second access.

相应的,终端设备从AMF接收注册响应消息。Correspondingly, the terminal device receives the registration response message from the AMF.
可以理解,若AMF确定接受终端设备注册,则向终端发送注册接受消息。若AMF确定不接受终端设备注册,则向终端发送注册拒绝消息。It can be understood that if the AMF determines to accept the registration of the terminal device, it sends a registration acceptance message to the terminal. If the AMF determines that it does not accept the registration of the terminal device, it sends a registration rejection message to the terminal.
S203、终端设备向AMF发送注册确认消息。S203, the terminal device sends a registration confirmation message to the AMF.

If the registration process is a registration process of the terminal device on the non-3GPP access, the terminal device and the AMF interact through the non-3GPP access mode.
步骤S203为可选步骤。Step S203 is an optional step.
本申请实施例还提供一种通信方法,参见图11,该方法包括:The embodiment of the present application also provides a communication method, see FIG. 11 , the method includes:
S301、第一设备根据第一接入的连接管理状态(connection management state,CM state)和第二接入的连接管理状态,选择第二接入。S301. The first device selects the second access according to the connection management state (connection management state, CM state) of the first access and the connection management state of the second access.
其中,第一接入是3GPP接入,且第二接入是非3GPP接入;或,第一接入是非3GPP接入,且第二接入是3GPP接入。Wherein, the first access is a 3GPP access, and the second access is a non-3GPP access; or, the first access is a non-3GPP access, and the second access is a 3GPP access.
作为一种可能的实现方式,第一设备维护有第一接入的连接管理状态和第二接入的连接管理状态。具体的,第一设备通过3GPP接入进入连接态或空闲态后,可以维护3GPP接入的连接管理状态,即维护3GPP接入的连接态(或空闲态)。第一设备通过非3GPP接入进入连接态(或空闲态)后,可以维护3GPP接入的连接态(或空闲态)。As a possible implementation manner, the first device maintains the connection management state of the first access and the connection management state of the second access. Specifically, after the first device enters the connected state or the idle state through the 3GPP access, it can maintain the connection management state of the 3GPP access, that is, maintain the connected state (or idle state) of the 3GPP access. After the first device enters the connected state (or idle state) through the non-3GPP access, it can maintain the connected state (or idle state) of the 3GPP access.
后续,第一设备可查询所维护的第一接入的连接管理状态和第二接入的连接管理状态,并根据该两个连接管理状态,选择用于发送第三NAS消息的接入。Subsequently, the first device may query the maintained connection management state of the first access and the connection management state of the second access, and select the access for sending the third NAS message according to the two connection management states.
作为一种可能的实现方式,第一设备选择连接管理状态为连接态的接入用来发送第三NAS消息。以第一接入的连接管理状态为空闲态,第二接入的连接管理状态为连接态为例,即第一设备选择第二接入用来发送第三NAS消息。As a possible implementation manner, the first device selects the access whose connection management state is the connection state to send the third NAS message.

其中,第三指示信息用于指示根据第一接入对应的方式处理第三NAS消息。The third indication information is used to indicate that the third NAS message is processed according to the mode corresponding to the first access.
现有技术中,当第一接入处于空闲态,为了在第一接入(比如3GPP接入)上发送NAS消息,还需重新建立终端设备和AMF之间的链路,消息发送有一定时延。In the prior art, when the first access is in an idle state, in order to send a NAS message on the first access (such as a 3GPP access), the link between the terminal device and the AMF needs to be re-established, and the message is sent for a certain period of time. extension.

The second device sends the third NAS message to shorten the message sending delay.
此外,与图7对应的实施例基于相同原理,第一设备发送的第三NAS消息包括第三指示信息,以便指示第二设备根据第一接入对应的方式处理第三NAS消息,即第二设备通过第二接入对应的协议实体(或称实例)接收第三NAS消息后,可以将该第三 NAS消息传递给第一接入对应的协议实体来处理。In addition, the embodiment corresponding to FIG. 7 is based on the same principle, and the third NAS message sent by the first device includes third indication information, so as to instruct the second device to process the third NAS message according to the mode corresponding to the first access, that is, the second After receiving the third NAS message through the protocol entity (or instance) corresponding to the second access, the device may transfer the third NAS message to the protocol entity corresponding to the first access for processing.
作为一种可能的实现方式,第三NAS消息包括第二信息单元,第二信息单元包括第三指示信息,第三指示信息用于指示根据第一接入对应的方式处理第二信息单元。即第三指示信息包括在第三NAS消息的IE中。As a possible implementation manner, the third NAS message includes a second information element, and the second information element includes third indication information, where the third indication information is used to instruct to process the second information element according to a manner corresponding to the first access. That is, the third indication information is included in the IE of the third NAS message.
第三NAS消息的具体实现可参见上述第二NAS消息。For the specific implementation of the third NAS message, reference may be made to the above-mentioned second NAS message.
S303、第二设备根据第一接入对应的方式处理第三NAS消息。S303. The second device processes the third NAS message according to the mode corresponding to the first access.
可选的,若第三指示信息包括在第三NAS消息的第二IE中,则第二设备根据第一接入对应的方式处理该第二IE。即第二设备的第二接入的协议实体将第二IE转发给第一接入的协议实体来处理。Optionally, if the third indication information is included in the second IE of the third NAS message, the second device processes the second IE according to the mode corresponding to the first access. That is, the protocol entity of the second access of the second device forwards the second IE to the protocol entity of the first access for processing.
或,第三指示信息包括在第三NAS消息的第二IE之外,则第二设备的第二接入的协议实体将该第三NAS消息转发给第一接入的协议实体来处理。Or, if the third indication information is included outside the second IE of the third NAS message, the protocol entity of the second access of the second device forwards the third NAS message to the protocol entity of the first access for processing.
第二IE,指的是第三NAS消息包括的现有技术的IE。第三指示信息包括在第三NAS消息的第二IE之外,指的是在现有的第三NAS消息的基础上,新增IE,在该新增IE中包括第三指示信息,用于指示整个第三NAS消息与哪种接入类型对应。The second IE refers to the prior art IE included in the third NAS message. The third indication information is included in addition to the second IE of the third NAS message, which means that an IE is added on the basis of the existing third NAS message, and the newly added IE includes the third indication information, which is used for Indicates which access type the entire third NAS message corresponds to.
S304、第二设备向第一设备发送第二响应消息。S304. The second device sends a second response message to the first device.
相应的,第一设备从第二设备接收第二响应消息。Correspondingly, the first device receives the second response message from the second device.
第二响应消息用于指示已接收第三NAS消息。The second response message is used to indicate that the third NAS message has been received.
作为一种可能的实现方式,第二设备通过第二接入向第一设备发送第二响应消息。即,第二设备的第一接入对应的协议实体(或称实例)处理完第三NAS消息后,将处理结果传递给第二接入对应的协议实体,第二接入对应的协议实体根据处理结果向第一设备发送第二响应消息。所述第二响应消息包括第四指示信息,所述第四指示信息用于指示所述第二响应消息对应于所述第一接入。As a possible implementation manner, the second device sends a second response message to the first device through the second access. That is, after the protocol entity (or instance) corresponding to the first access of the second device has processed the third NAS message, it transmits the processing result to the protocol entity corresponding to the second access, and the protocol entity corresponding to the second access is based on the The processing result sends a second response message to the first device. The second response message includes fourth indication information, where the fourth indication information is used to indicate that the second response message corresponds to the first access.
或,第二设备通过第一接入的协议实体向第一设备发送第二响应消息。Or, the second device sends the second response message to the first device through the first accessed protocol entity.
步骤S304为可选步骤。Step S304 is an optional step.
在一些实施例中,在第一设备通过第二接入向第二设备发送与第一接入对应的第三NAS消息之前,还包括:In some embodiments, before the first device sends the third NAS message corresponding to the first access to the second device through the second access, the method further includes:
第一设备向第二设备发送能力信息;能力信息用于指示第一设备能够通过第二接入传输第一接入对应的NAS消息。The first device sends capability information to the second device; the capability information is used to indicate that the first device can transmit a NAS message corresponding to the first access through the second access.
在一些实施例中,第一设备向第二设备发送能力信息,包括:In some embodiments, the first device sends capability information to the second device, including:

与现有技术中在连接管理状态为空闲态的接入上发送消息,需先建立相关通信链路,比如,先建立RRC连接,再通过RRC连接通信,业务时延较大相比,本申请实施例提供的通信方法,根据第一接入的连接管理状态和第二接入的连接管理状态,选择第二接入,并在第二接入上发送第三NAS消息。也就是说,在选择用来发送NAS消息的接入时,还考虑多个可用接入各自的连接管理状态。能够降低选择空闲态接入的概率,进而降低业务时延。此外,第三NAS消息包括第三指示信息,能够指示第二 设备根据第一接入对应的方式处理第三NAS消息,以便于第二设备能够正确处理第三NAS消息。Compared with the prior art, when a message is sent on an access whose connection management state is in an idle state, a relevant communication link needs to be established first. In the communication method provided by the embodiment, the second access is selected according to the connection management state of the first access and the connection management state of the second access, and a third NAS message is sent on the second access. That is, the respective connection management states of the multiple available accesses are also considered when selecting the access for sending the NAS message. The probability of selecting idle state access can be reduced, thereby reducing service delay. In addition, the third NAS message includes third indication information, which can instruct the second device to process the third NAS message according to the mode corresponding to the first access, so that the second device can correctly process the third NAS message.
