Antenna Line Device Management Method, and Device

A primary device, comprising:

• a processor;
• and
• a transceiver, configured to:
• send a scanning command to an antenna line device, wherein the scanning command is used to scan the antenna line device;
• and
• receive a scanning response sent by the antenna line device, wherein the scanning response comprises indication information indicating a type of the antenna line device, wherein the type of the antenna line device is a container antenna line device, the container antenna line device has a capability of managing a plurality of subdevices, and connection lines between all ports of the container antenna line device and a processor of a first antenna line device are different from each other;
• send a High-Level Data Link Control (HDLC) address assignment command to the antenna line device, wherein the HDLC address assignment command comprises an HDLC address assigned by the primary device to the antenna line device;
• wherein the processor is configured to establish a communication link to the antenna line device according to the HDLC address;
• wherein the transceiver is further configured to send a capability information query command to the antenna line device;
• wherein the transceiver is further configured to receive a capability information report sent by the antenna line device, wherein the capability information report comprises function information of each of N subdevices managed by the antenna line device, wherein N is an integer greater than or equal to 0;
• and
• wherein the processor is further configured to manage the N subdevices according to the capability information report.
