首先对本申请实施例涉及的技术术语和应用场景进行介绍：First, the technical terms and application scenarios involved in the embodiments of the present application are introduced:
当网络侧设备为了获取终端中的数据需要与终端之间建立数据面连接时，可能存在多条潜在路径，例如该数据面连接可以基于用户面路径(用户面协议栈)、控制面路径(控制面协议栈)，可选地，数据面连接也可以基于新定义的数据面路径(数据面协议栈)。但终端和网络侧设备之间如何确定以及如何协商选择其中一条路径承载数据面连接目前并不清楚。When the network side device needs to establish a data plane connection with the terminal in order to obtain data in the terminal, there may be multiple potential paths, for example, the data plane connection can be based on the user plane path (user plane protocol stack), the control plane path (control plane protocol stack), and optionally, the data plane connection can also be based on a newly defined data plane path (data plane protocol stack). However, it is not clear how the terminal and the network side device determine and negotiate to select one of the paths to carry the data plane connection.
终端和网络侧设备之间的数据面连接上的数据传输可能存在多种数据编码方式，基于JavaScript对象标记(JavaScript Object Notation，JSON)、抽象语法标记(Abstract Syntax Notation One，ASN.1)、(Protocol Buffer，Protobuf)、可扩展标记语言(Extensible Markup Language，XML)、仍是一种标记语言(Yet Another Markup Language，YAML)、消息报MessagePack、二进制JSON(Binary JSON，BSON)等数据序列化方式，且每种方式有各自的特点，具体如下：There may be multiple data encoding methods for data transmission on the data plane connection between the terminal and the network side device, based on JavaScript Object Notation (JSON), Abstract Syntax Notation One (ASN.1), Protocol Buffer (Protobuf), Extensible Markup Language (XML), Yet Another Markup Language (YAML), Message Pack, Binary JSON (BSON) and other data serialization methods, and each method has its own characteristics, as follows:
JSON：一种轻量级的数据交换格式，易于阅读和编写，支持多种编程语言，常用于网络(Web)应用程序中。但JSON为基于文本的，数据编码和传输效率低。JSON: A lightweight data exchange format that is easy to read and write, supports multiple programming languages, and is commonly used in network (Web) applications. However, JSON is text-based, and has low data encoding and transmission efficiency.
ASN.1：具有编码紧凑、类型安全、互操作性好等优点，但需要使用专门的编解码工具和规则，实现难度较大。ASN.1: It has the advantages of compact coding, type safety, and good interoperability, but it requires the use of special encoding and decoding tools and rules, which makes it difficult to implement.
Protocol Buffer：一种高效的二进制序列化格式，支持多种编程语言，常用于大规模分布式系统。Protocol Buffer: An efficient binary serialization format that supports multiple programming languages and is often used in large-scale distributed systems.
XML：一种标记语言，用于描述数据，支持多种编程语言，常用于Web应用程序和数据交换。XML: A markup language used to describe data that supports multiple programming languages and is commonly used in web applications and data exchange.
YAML：一种人类可读的数据序列化格式，用于配置文件和数据交换，支持多种编程语言。YAML: A human-readable data serialization format for configuration files and data exchange, supporting multiple programming languages.
MessagePack：一种高效的二进制序列化格式，支持多种编程语言，比JSON更快、更小。MessagePack: An efficient binary serialization format that supports multiple programming languages and is faster and smaller than JSON.
BSON：一种二进制JSON格式，支持更多的数据类型和更好的性能，常用于MongoDB数据库。BSON: A binary JSON format that supports more data types and better performance, commonly used in MongoDB databases.
但终端和网络侧设备之间如何根据不同的需求选择和协商数据编码方式也并不清楚。However, it is not clear how the terminal and network-side devices select and negotiate data encoding methods based on different requirements.
图2中示出了数据面架构，终端和网络侧设备之间的数据面(Data Plane，DP)连接，例如，终端为数据来源(data source)；Figure 2 shows the data plane architecture, the data plane (DP) connection between the terminal and the network side device, for example, the terminal is the data source;
其中，DP-C和DP-U是终端内部与数据面相关的两个模块：Among them, DP-C and DP-U are two modules related to the data plane inside the terminal:
1、DP-C是数据面控制模块，用于控制数据面建立、修改和删除相关信令。1. DP-C is the data plane control module, which is used to control the establishment, modification and deletion of related signaling of the data plane.
2、DP-U是数据面转发模块，用于采集、处理和转发终端内相关数据。2. DP-U is the data plane forwarding module, which is used to collect, process and forward relevant data in the terminal.
对应地，核心网侧有相应的网元(如数据面功能(Data Plane Function，DPF))与终端内上述两个模块对应：Correspondingly, there are corresponding network elements on the core network side (such as Data Plane Function (DPF)) corresponding to the above two modules in the terminal:
1、DPF-C是数据面控制网元，用于控制数据面建立、修改和删除相关信令。1. DPF-C is the data plane control network element, which is used to control the establishment, modification and deletion of related signaling of the data plane.
2、DPF-U是数据面转发网元，用于采集、处理和转发终端、RAN或其他数据来源的相关数据。2. DPF-U is a data plane forwarding network element, which is used to collect, process and forward relevant data from terminals, RAN or other data sources.
需要说明的是，上述核心网侧的网元可以是其他网元名称，或者被其他类似功能的网元代替，如数据收集协调功能(Data Collection Coordination Function，DCCF)网元，或消息框架适配网元(The Messaging Framework Adaptor Function，MFAF)。It should be noted that the above-mentioned network elements on the core network side can be other network element names, or be replaced by network elements with other similar functions, such as the data collection coordination function (DCCF) network element, or the messaging framework adapter function (MFAF) network element.
其中，终端的数据面相关信令(即DP-C模块控制的信令)，可以基于不同的协议栈与核心网侧DPF-C交互。例如图2中线条2所示：Among them, the data plane related signaling of the terminal (i.e., the signaling controlled by the DP-C module) can interact with the DPF-C on the core network side based on different protocol stacks. For example, as shown by line 2 in Figure 2:
1、基于现有的CP面协议栈(如非接入层(Non-Access Stratum，NAS)和底层接入层AS协议层)；1. Based on the existing CP-plane protocol stack (such as the non-access layer (NAS) and the underlying access layer AS protocol layer);
2、基于新增的DP协议栈(如数据层协议(Data stratum Protocol 1，DsP1)，分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)等，其中DsP1是终端和RAN之间数据面对等协议层)；2. Based on the newly added DP protocol stack (such as Data stratum Protocol 1 (DsP1), Packet Data Convergence Protocol (PDCP), etc., where DsP1 is the data interface peer protocol layer between the terminal and RAN);
需要说明的是，终端和网络侧之间的DP面协议栈可以经过(over)或不经过DsP1协议层。It should be noted that the DP plane protocol stack between the terminal and the network side may pass through (over) or not pass through the DsP1 protocol layer.
当经过DsP1层的情况下，RAN可以解析DsP1协议层，可以获取并解析终端向核心网侧传递的所述数据中的部分或全部信息，有利于RAN中数据面模块获得相关信息。When passing through the DsP1 layer, the RAN can parse the DsP1 protocol layer, and can obtain and parse part or all of the information in the data transmitted by the terminal to the core network side, which is conducive to the data plane module in the RAN to obtain relevant information.
如果不经过DsP1的情况下，RAN则透传终端向核心网侧传递的所述数据。If the data does not pass through DsP1, RAN transparently transmits the data transmitted by the terminal to the core network side.
同样，终端的数据面的数据转发(即DP-U模块处理后的数据)，可以基于不同的协议栈与核心网DPF-U交互。例如图2中线条1所示：Similarly, the data forwarding of the terminal's data plane (i.e., the data processed by the DP-U module) can interact with the core network DPF-U based on different protocol stacks. For example, as shown in line 1 in Figure 2:
1、基于CP面协议栈(如NAS和底层AS协议层)；1. Based on the CP-side protocol stack (such as NAS and the underlying AS protocol layer);
2、基于UP面协议栈(如IP，业务数据适配协议(Service Data Adaptation Protocol，SDAP)，PDCP等)2. Based on UP protocol stack (such as IP, Service Data Adaptation Protocol (SDAP), PDCP, etc.)
3、基于DP面协议栈(如DsP1，PDCP等，其中DsP1是终端和RAN之间数据面对等协议层)3. Based on the DP plane protocol stack (such as DsP1, PDCP, etc., where DsP1 is the data plane peer protocol layer between the terminal and RAN)
