数据传输的方法和装置Method and device for data transmission
本申请要求于2019年1月23日提交中国专利局、申请号为201910063625.5、申请名称为“数据传输的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。This application claims the priority of a Chinese patent application filed with the Chinese Patent Office with the application number 201910063625.5 and the application title "Data Transmission Method and Device" on January 23, 2019, the entire content of which is incorporated into this application by reference.
技术领域Technical field
本申请涉及通信领域，更具体地，涉及一种数据传输的方法和装置。This application relates to the field of communications, and more specifically, to a method and device for data transmission.
背景技术Background technique
在传统的数据传输架构下，终端设备的数据经过基站和固定的用户面功能(user plane function，UPF)与数据网络(data network，DN)进行通信。具体地，终端设备在接入基站后，会议管理功能(session management function，SMF)会为终端设备选择好固定的UPF，网络设备为终端设备建立终端设备-基站-UPF-DN的固定通道，其中基站和UPF之间的通道可以是通用分组无线服务隧道协议(general packet radio service tunneling protocol，GTP)通道。Under the traditional data transmission architecture, the data of the terminal device communicates with the data network (DN) through the base station and the fixed user plane function (UPF). Specifically, after the terminal device accesses the base station, the session management function (SMF) will select a fixed UPF for the terminal device, and the network device establishes a fixed channel of the terminal device-base station-UPF-DN for the terminal device. The channel between the base station and the UPF may be a general packet radio service tunneling protocol (general packet radio service tunneling protocol, GTP) channel.
其中，可以是一个基站与一个UPF建立GTP通道，也可以是多个基站分别与同一个UPF建立GTP通道。尤其在多个基站与同一个UPF建立GTP通道的情况下，由于终端设备只能通过固定的UPF进行数据传输，则当UPF的业务拥塞时，该UPF下的终端设备的数据会受到影响，从而使得数据传输的效率较低。Among them, one base station may establish a GTP channel with one UPF, or multiple base stations may establish a GTP channel with the same UPF respectively. Especially when multiple base stations establish GTP channels with the same UPF, since terminal equipment can only transmit data through a fixed UPF, when the UPF service is congested, the data of the terminal equipment under the UPF will be affected. Makes the efficiency of data transmission low.

图1是本申请一个通信***的示意图，以5G通信***为例。图1中的通信***可以包括接入移动性管理功能(access and mobility management function，AMF)、SMF、DN、UPF、无线接入网(radio access network，RAN)和UE。SMF用于负责会话管理，AMF用于负责接入和移动性管理。比如AMF、SMF、DN、UPF都是核心网设备的功能性描述，基站是接入网设备的功能性描述。Fig. 1 is a schematic diagram of a communication system of the present application, taking a 5G communication system as an example. The communication system in FIG. 1 may include access and mobility management function (AMF), SMF, DN, UPF, radio access network (RAN), and UE. SMF is used for session management, and AMF is used for access and mobility management. For example, AMF, SMF, DN, and UPF are all functional descriptions of core network equipment, and base stations are functional descriptions of access network equipment.
在传统的数据传输架构下，终端设备的数据经过基站和固定的UPF与DN进行通信。具体地，终端设备在接入基站后，SMF会为终端设备选择好固定的UPF，并建立终端设备-基站-UPF-DN的固定通道，其中基站和UPF之间的通道可以是GTP通道。具体地，固定UPF对应终端设备的某一PDU会话，对应性的，上述固定通道对应终端设备的某一PDU会话的固定通道。Under the traditional data transmission architecture, the data of the terminal equipment communicates with the DN through the base station and the fixed UPF. Specifically, after the terminal device accesses the base station, the SMF will select a fixed UPF for the terminal device and establish a fixed channel of terminal device-base station-UPF-DN, where the channel between the base station and the UPF may be a GTP channel. Specifically, the fixed UPF corresponds to a certain PDU session of the terminal device, and correspondingly, the above-mentioned fixed channel corresponds to a fixed channel of a certain PDU session of the terminal device.
其中，可以是一个基站与一个UPF建立GTP通道，也可以是多个基站分别与同一个UPF建立GTP通道。尤其在多个基站与同一个UPF建立GTP通道的情况下，由于UE只能通过固定的UPF进行数据传输(例如，如图2所示，UE-1只能通过UPF1向DN发送对应的PDU会话数据)，则当UPF的业务拥塞时，该UPF下的终端设备的数据会受到影响，从而使得数据传输的效率较低。Among them, one base station may establish a GTP channel with one UPF, or multiple base stations may establish a GTP channel with the same UPF respectively. Especially when multiple base stations establish GTP channels with the same UPF, since the UE can only transmit data through a fixed UPF (for example, as shown in Figure 2, UE-1 can only send the corresponding PDU session to the DN through UPF1 Data), when the service of the UPF is congested, the data of the terminal equipment under the UPF will be affected, so that the efficiency of data transmission is low.

As an implementation of sending, each of the at least two transmission node devices and the data channel of the access network device correspond to the same PDU session service of the terminal device. In this way, the access network device can directly send the target data to the DN through the selected target transmission node device. Compared with the traditional solution, the target data can only use a fixed transmission node device for data transmission, which causes data congestion. The embodiment of the application can be flexibly selected Transmission node equipment, thereby improving communication efficiency.
