Embodiment Construction

[0024] In the embodiment of the present invention, since the Device Scan Command message broadcast by the CCU may not carry the UniqueID', and the RCU does not need to perform the matching operation of the UniqueID after receiving the Device Scan Command message broadcast by the CCU, but directly carries the UniqueID with its own The DeviceScan Response message of UniqueID is fed back to the CCU, and the CCU further assigns an address to the remote control unit that sends the device scan response message, thereby greatly shortening the scanning time of the CCU to the RCU.

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as image 3 As shown, it is a flow chart of the device scanning method in the electrically adjustable antenna interface in the embodiment of the present invention.

[0027] Step 301 , storing information of all RCUs controlled by the CCU in a preset information table, t...

Abstract

The invention discloses a method for scanning equipment in an electrically adjustable antenna interface, which comprises that: a central control unit broadcasts an equipment scanning request message to each far-end control unit controlled by the central control unit, and receives an equipment scanning response message sent by a far-end control unit in a no-address state; and the central control unit allocates an address for the far-end control unit sending the equipment scanning response message. The invention also discloses a device and a system for scanning equipment in the electrically adjustable antenna interface. By adopting the scheme, the far-end control unit does not need performing unique identification code matching operation so as to shorten the time for scanning the far-end control unit by the central control unit.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a device scanning method, device and system in an electrically adjustable antenna interface. Background technique [0002] The Antenna Interface Standards Group (AISG, Antenna Interface Standards Group) protocol stipulates that any antenna array device (ALD, Antenna Line Device) needs a globally unique unique identification code (UniqueID). This UniqueID needs to be obtained by scanning. The scanning process is as follows: figure 1 As shown, the process includes the following steps: [0003] Step 101: The central control unit (CCU, Central Control Unit) in the base station sends a device scan request (Device ScanCommand) message with a virtual unique identification code (UniqueID') and a bit mask (Bitmask) in a broadcast manner to all ALDs connected to the bus. [0004] Among them, UniqueID' is generally a part of UniqueID, and the two parameters of Bitmask and Uni...
