Embodiment 1

[0026] figure 1 It is a flow chart of the radio frequency bypass switching control method provided in Embodiment 1 of the present invention, as shown in figure 1 As shown, the radio frequency bypass switching control method may include:

[0027] Step 101, the radio frequency controller locks the number of hops of each radio frequency device connected in series;

[0028] Specifically, the operating environment of base stations (including radio frequency equipment and radio frequency controllers, etc.) can be divided into two types according to work scenarios: centralized operation and maintenance stages such as station opening, capacity expansion, and commissioning, and stable operations with occasional or no operation and maintenance run phase. The duration of the centralized operation and maintenance phase is short, usually measured in hours. The installation and replacement of radio frequency equipment (RE) is carried out during the centralized operation and maintenance ph...

Embodiment 2

[0047] figure 2 A flow chart of the radio frequency bypass switching control method provided in Embodiment 2 of the present invention, as shown in figure 2 As shown, on the basis of Embodiment 1, the radio frequency bypass switching control method may specifically include:

[0048] Step 201, REC can be in HOP detection mode by default. In the centralized operation and maintenance phase, REC initiates HOP detection to RE according to the set period and saves the detection results. The detection results can include the hop count of RE in HOP detection mode, which is generally normal operation. The number of jumps when

[0049] In step 202, the REC initiates an HDLC broadcast to the REs according to a set period to obtain and store the serial numbers of each RE. In this step, the serial number of the RE may not be used for HDLC link establishment determination, but may be used as business auxiliary data management; step 201 and step 202 can be executed at the same time, step ...

Embodiment 3

[0064] image 3 A schematic structural diagram of a radio frequency controller provided in Embodiment 3 of the present invention, as shown in image 3 As shown, the RF controller can include:

[0065] A locking module 11, configured to lock the hops of each radio frequency device connected in series;

[0066] The configuration sending module 13 is configured to send corresponding configuration data to the radio frequency device that has not undergone bypass switching according to the hop count locked by the locking module 11 if a radio frequency device is bypassed.

[0067] Specifically, the operating environment of the base station can be divided into two types according to the working scenarios: centralized operation and maintenance stages such as station opening, capacity expansion, and commissioning, and stable operation stages with occasional operation and maintenance or no operation and maintenance. In the centralized operation and maintenance phase, the radio frequenc...

Abstract

The invention discloses a method, a system and a radio frequency (RF) controller for controlling RF bypass switch. The method includes that the RF controller locks the hop number of each RF equipment which configures the network in series (101); if an RF equipment switches to bypass, according to the locked hop numbers, the RF controller distributes the corresponding configuration data to the RF equipments which do not switch to bypass (102). The RF controller in the embodiment of the invention can lock the hop number of each RF equipment which configures the network in series; when a certain RF equipment encounters abnormal power-down which results in the RF equipment switching to bypass automatically, according to the locked hop numbers, the RF controller distributes the corresponding configuration data to the RF equipments which do not switch to bypass. The invention can ensure that the RF equipments which do not switch to bypass operate according to the configuration and state before the hop numbers are locked, so that the reliability of configuring the network in series by RF units is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a radio frequency bypass switching control method, system and radio frequency controller. Background technique [0002] Existing base stations achieve wide coverage and save baseband costs through remote radio frequency. The baseband is connected to the remote radio frequency unit by optical fiber. One remote radio frequency unit can be connected with two optical fibers to support series connection and ring connection. Control (High level Data Link Control; abbreviation: HDLC) and common public radio interface (abbreviation: CPRI) protocol to realize data exchange. The baseband part is mainly responsible for the detection, link building, operation and maintenance of the radio frequency unit, which is called Radio Equipment Control (abbreviation: REC); the radio frequency unit is in the subordinate managed position, called radio equipment (Ra...
