阅读说明：本技术 一种通信方法及设备 (Communication method and device ) 是由 姚楚婷 何彦召 邝奕如 徐海博 王键 于 2020-04-17 设计创作，主要内容包括：本申请涉及一种通信方法及设备,其中的一种通信方法包括：终端设备确定能够通过SRB3向第一网络设备发送终端设备的辅助信息,终端设备连接至少两个网络设备,第一网络设备为至少两个网络设备中的辅网络设备；终端设备通过SRB3向第一网络设备发送辅助信息,辅助信息用于指示终端设备所期望的配置或终端设备的业务信息。终端设备可以通过SRB3向作为辅网络设备的第一网络设备发送终端设备的辅助信息,那么辅网络设备也能获得终端设备的辅助信息,从而辅网络设备可以对终端设备进行相应的配置,不至于使终端设备释放与辅网络设备之间的连接,从而有助于提高终端设备的传输性能。(The application relates to a communication method and a device, wherein the communication method comprises the following steps: the terminal device determines that auxiliary information of the terminal device can be sent to a first network device through the SRB3, the terminal device is connected with at least two network devices, and the first network device is an auxiliary network device of the at least two network devices; the terminal device sends the auxiliary information to the first network device via SRB3, where the auxiliary information is used to indicate the configuration desired by the terminal device or the service information of the terminal device. The terminal device may send the auxiliary information of the terminal device to the first network device serving as the auxiliary network device through SRB3, so that the auxiliary network device may also obtain the auxiliary information of the terminal device, and the auxiliary network device may perform corresponding configuration on the terminal device, which may not cause the terminal device to release the connection with the auxiliary network device, thereby facilitating improvement of the transmission performance of the terminal device.)
