Of course, the technical solutions of the embodiments of the present application are not limited to 5G mobile communication systems, but can also be applied to other types of mobile communication systems. To facilitate understanding of the technical solutions of the embodiments of the present application, the following describes related technologies involved in the embodiments of the present application. It should be noted that the following related technologies also fall within the protection scope of the embodiments of the present application.

URLLC的数据需要冗余传输来保证，为此需要3GPP网络建立多个会话来实现，需要说明的是，本申请实施例中的“多个”的意思包括两个或者大于两个，一种典型的实现方式是两个；此外，“会话”的意思包括但不局限于协议数据单元(Protocol Data Unit，PDU)会话。The data of URLLC needs to be redundantly transmitted to ensure. For this purpose, multiple sessions need to be established by the 3GPP network. It should be noted that the meaning of "multiple" in the embodiments of the present application includes two or more than two, a typical Is implemented in two ways; in addition, the meaning of "session" includes but is not limited to a protocol data unit (Protocol Data Unit, PDU) session.

举个例子：参照图2(a)，冗余传输是一个用户模块(简称为UE)通过两个PDU会话来传输同一应用数据。参照图2(b)，冗余传输是两个UE通过两个PDU会话来传输同一应用数据，其中，每个UE上建立有一个PDU会话。可见，冗余传输的实现是将同一应用数据通过多个会话进行传输，多个会话对应于同一个UE或不同的UE。对于一个UE上建立有两个PDU会话的流程，参照图3所示，包括如下流程：1、建立PDU会话1；2、建立PDU会话2；3、在无线接入网络(Radio Access Network，RAN)建立双连接；4、针对PDU会话2进行路径选择。对于两个UE上分别建立1个PDU会话(总共是2个PDU会话)的情况，参照图4，两个UE根据基站广播的可靠组(Reliability Group，RG)来接入不同的基站或小区(如图4中的gNB1和gNB2)，UE也可以用参数比如S-NSSAI、频点优先级等实现接入不同的基站或小区。For example, referring to FIG. 2(a), redundant transmission is that a user module (referred to as UE for short) transmits the same application data through two PDU sessions. Referring to FIG. 2(b), redundant transmission is that two UEs transmit the same application data through two PDU sessions, where one PDU session is established on each UE. It can be seen that the implementation of redundant transmission is to transmit the same application data through multiple sessions, and the multiple sessions correspond to the same UE or different UEs. For the process of establishing two PDU sessions on one UE, refer to FIG. 3, which includes the following processes: 1. Establishing PDU session 1; 2. Establishing PDU session 2; 3. In the radio access network (Radio Access Network, RAN ) Establish dual connection; 4. Path selection for PDU session 2. For a case where two PDU sessions are established on two UEs (a total of two PDU sessions), referring to FIG. 4, the two UEs access different base stations or cells according to the reliability group (Reliability Group, RG) broadcast by the base station ( As shown in gNB1 and gNB2 in FIG. 4), the UE may also use parameters such as S-NSSAI and frequency priority to achieve access to different base stations or cells.

参照图5(b)，图5(b)为两个UE情况下的PDU会话建立的示意图一，其中，在图5(b)中，应用层发起一次建立请求，OS层发起两次建立请求。具体地，终端从上到下包括：应用层、操作***(Operating System，OS)层、UE-1、UE-2，进一步，UE-1包括NAS层和AS层，UE-2包括NAS层和AS层。其中，应用层向OS层发起建立请求，该建立请求携带应用标识(APP ID)；OS层向UE-1的NAS层发起建立请求-1，以及向UE-2的NAS层发起建立请求-2，所述建立请求-1和所述建立请求-2携带相同的PDU会话的属性参数；UE-1的NAS层向AS层发起PDU-1会话建立请求，UE-2的NAS层向AS层发起PDU-2会话建立请求，而后，UE-1的AS层建立PDU-1会话，UE-2的AS层建立PDU-2，通过这两个PDU会话传输同一应用数据。Referring to FIG. 5(b), FIG. 5(b) is a schematic diagram 1 of PDU session establishment in the case of two UEs. In FIG. 5(b), the application layer initiates a setup request and the OS layer initiates two setup requests. . Specifically, the terminal includes, from top to bottom, an application layer, an operating system (OS) layer, UE-1, and UE-2.

参照图5(c)，图5(c)为两个UE情况下的PDU会话建立的示意图二，其中，在图5(c)中，应用层发起两次建立请求，OS层发起两次建立请求。具体地，终端从上到下包括：应用层、操作***(Operating System，OS)层、UE-1、UE-2，进一步，UE-1包括NAS层和AS层，UE-2包括NAS层和AS层。其中，应用层向OS层发起建立请求1和建立请求2，所述建立请求1和所述建立请求2携带相同的应用标识(APP ID)；OS层向UE-1的NAS层发起建立请求-1，以及向UE-2的NAS层发起建立请求-2，所述建立请求-1和所述建立请求-2携带相同的PDU会话的属性参数；UE-1的NAS层向AS层发起PDU-1会话建立请求，UE-2的NAS层向AS层发起PDU-2会话建立请求，而后，UE-1的AS层建立PDU-1会话，UE-2的AS层建立PDU-2，通过这两个PDU会话传输同一应用数据。Referring to FIG. 5(c), FIG. 5(c) is a second schematic diagram of PDU session establishment in the case of two UEs, where in FIG. 5(c), the application layer initiates two establishment requests and the OS layer initiates two establishments. request. Specifically, the terminal includes, from top to bottom, an application layer, an operating system (OS) layer, UE-1, and UE-2. Further, UE-1 includes a NAS layer and an AS layer, and UE-2 includes a NAS layer and AS layer. Among them, the application layer initiates establishment request 1 and establishment request 2 to the OS layer, the establishment request 1 and the establishment request 2 carry the same application ID (APP ID); the OS layer initiates the establishment request to the NAS layer of UE-1- 1, and initiate a setup request-2 to the NAS layer of UE-2, the setup request-1 and the setup request-2 carry the same attribute parameters of the PDU session; the NAS layer of UE-1 initiates the PDU- to the AS layer 1 Session establishment request, the NAS layer of UE-2 initiates a PDU-2 session establishment request to the AS layer, and then, the AS layer of UE-1 establishes a PDU-1 session, and the AS layer of UE-2 establishes PDU-2. One PDU session transmits the same application data.

另一方面，应用数据与PDU会话的绑定通过UE策略(UE policy)来执行，一个UE policy可以有多个规则(rule)，每一个规则的内容如下表1至表3所示：On the other hand, the binding of the application data and the PDU session is performed through the UE policy (UE policy). A UE policy can have multiple rules, and the content of each rule is shown in Table 1 to Table 3:

表1：UE Route Selection PolicyTable 1: UERouteSelectionPolicy

表2：Route Selection DescriptorTable 2: Route Selection Descriptor

表3：Route Selection DescriptorTable 3: Route Selection Descriptor

从上述表1至表3可以看到，该规则分为两部分，第一部分是业务描述(Traffic Descriptor)、第二部分是路由选择描述(RSD，Route Selection Descriptor)。其中，Traffic Descriptor是用来描述特定的应用数据流的特征的，对于特定的应用数据流会有对应的一个或多个RSD，终端会按照RSD来发起PDU会话的建立，其中在PDU会话建立请求中携带RSD中包含的属性参数，以使得网络侧建立特定特征的PDU会话。As can be seen from Tables 1 to 3 above, the rule is divided into two parts. The first part is the service description (Traffic Descriptor), and the second part is the routing description (RSD, Route Selection Descriptor). Among them, Traffic Descriptor is used to describe the characteristics of a specific application data stream. For a specific application data stream, there will be one or more RSDs. The terminal will initiate the establishment of a PDU session according to the RSD. It carries the attribute parameters contained in the RSD, so that the network side establishes a PDU session with specific characteristics.

对于Traffic Descriptor，主要用于终端的应用层和OS层之间的交互，当OS层识别了特定的应用数据后，就会根据对应的RSD向UE发送PDU会话建立请求消息或将应用数据绑定到符合条件的已有的PDU会话中进行传输。因此，对于RSD，主要用于OS层和UE之间的交互。For Traffic Descriptor, it is mainly used for the interaction between the application layer and the OS layer of the terminal. After the OS layer recognizes the specific application data, it will send a PDU session establishment request message to the UE according to the corresponding RSD or bind the application data Transfer to existing PDU sessions that meet the conditions.

The specific execution judgment is described as follows:

对于每个新产生的上层应用数据，终端按照规则优先级的顺序评估URSP规则，并确定该应用数据是否匹配任何URSP规则的Traffic Descriptor。当发现应用标识， DNN或应用的描述信息与URSP规则中的Traffic Descriptor匹配时，终端应按照RSD优先级的顺序在该URSP规则中选择RSD。进一步，当在现有的PDU会话中存在匹配的PDU会话时，终端将应用数据与现有的PDU会话相关联，即，在将应用数据绑定到该现有的PDU会话上。如果现有的PDU会话都不匹配，则终端尝试使用选择的RSD指定的值建立新的PDU会话。基于上述应用数据与PDU会话的绑定机制，本申请实施例在RSD中增加一个参数(也即本申请实施例的第一信息)，该参数指示是否进行冗余传输(即是否执行本申请实施例的第一动作)，额外的，该参数可以指示是使用多少个UE的PDU会话的传输(比如，一个UE还是多个UE)，以及冗余传输的会话数量(比如2个或3个会话)。For each newly generated upper layer application data, the terminal evaluates the URSP rules in the order of rule priority, and determines whether the application data matches the Traffic Descriptor of any URSP rule. When the application identification, DNN or application description information matches the Traffic Descriptor in the URSP rule, the terminal shall select the RSD in the URSP rule in the order of the RSD priority. Further, when there is a matching PDU session in the existing PDU session, the terminal associates the application data with the existing PDU session, that is, binds the application data to the existing PDU session. If none of the existing PDU sessions match, the terminal attempts to establish a new PDU session using the value specified by the selected RSD. Based on the binding mechanism between the application data and the PDU session, the embodiment of the present application adds a parameter (that is, the first information in the embodiment of the present application) to the RSD, and the parameter indicates whether to perform redundant transmission (that is, whether to implement the implementation of the present application Example of the first action), additional, this parameter can indicate how many UEs are used for the transmission of PDU sessions (for example, one UE or multiple UEs), and the number of redundantly transmitted sessions (for example, 2 or 3 sessions) ).
