Description

传输数据的方法和装置 技术领域
本发明涉及通信领域，并且更具体地，涉及传输数据的方法和装置。
背景技术
在非独立(Non-standalone)网络的部署场景中，终端设备可以通过长期演进(Long Term Evolution，简称“LTE”)网络和新无线(New Radio，简称“NR”)网络同时接收或者发送数据，这一技术可以称其为多(双)连接技术。
终端设备的多(双)连接中存在一个主连接和一个或多个辅连接。主连接是终端设备和主网络设备的网络连接，辅连接是终端设备和辅网络设备的网络连接，例如，在LTE+NR小区的部署场景中，主网络设备可以为LTE网络的网络设备，辅网络设备可以为NR网络的网络设备。终端设备的控制面数据通过主链接传输，终端设备的用户面数据可以分成两路由主连接和辅连接同时传输，以提高用户面数据吞吐量；或者用户面数据也可以只通过辅连接传输，从而减轻主网络设备的负荷，但是，用户面数据或控制面数据的分流仅在数据传输过程中进行分流，随着网络吞吐量的增量，主网络设备的传输负荷越来越重，有必要进一步增加辅网络设备为主网络设备分流数据的能力。
发明内容
本发明实施例提供一种传输数据的方法和装置，能够降低主网络设备的传输负荷。
第一方面，提供了一种传输数据的方法，该方法包括：所述第一主网络设备接收终端设备在接入所述第一主网络设备的过程中发送的辅网络设备的测量结果信息，所述测量结果信息用于指示所述辅网络设备与所述终端设备之间的链路质量；所述第一主网络设备根据所述辅网络设备与所述终端设备之间的链路质量，确定建立所述辅网络设备与终端设备的辅连接；所述第一主网络设备建立所述辅连接。
这样，终端设备可以将辅网络设备的测量结果信息在接入第一主网络设 备的过程中发送给第一主网络设备，第一主网络设备在接收到终端设备的测量结果信息之后，根据该测量结果信息，确定需要建立辅网络设备与终端设备的之间的辅连接，然后该第一主网络设备建立该辅连接，终端设备通过该辅连接传输数据，这样，通过终端设备在接入过程中将辅网络设备的测量结果信息发送给第一主网络设备，可以将数据尽早地分流数据到辅网络设备，可以使得第一主网络设备建立的辅连接尽早地可以为第一主网络设备分流数据，可以降低第一主网络设备的传输负荷。
可选地，辅连接用于传输控制面数据和/或用户面数据，现有技术在数据连接过程中仅为第一主网络设备分担用户面数据，这样，第一主网络设备在终端设备接入第一主网络设备的过程中建立的辅连接不仅可以为第一主网络设备分担用户面数据的分流，也可以为第一主网络设备分担控制面数据的分流，进一步地增加了辅网络设备为主网络设备的分流能力，降低了第一主网络设备的传输负荷。
