The different baseband boards of different baseband boards or different baseband processing units；
Specifically, current mainstream base station uses baseband processing unit (Building Base band Unit, BBU) more
With the framework of Remote Radio Unit (Radio Remote Unit, RRU) separation, generally use optical fiber interconnects between BBU and RRU,
Therebetween interface is commonly known as IR (Interface between RRU and BBU, IR) interfaces or CPRI
(Common Public Radio Interface, CPRI) interface.Therefore, in embodiments of the present invention, above-mentioned interface is light
Mouthful, such as IR optical ports.When technical solution of the embodiment of the present invention is for solving to use annular networking between BBU and RRU, industry occurs for RRU
The process problem for failure of being engaged in, therefore, in the embodiment of the present invention, RRU and BBU use annular networking mode networking.
Technical solution of the embodiment of the present invention support single baseband board annular networking, across baseband board annular networking in single base station,
Across BBU several situations of annular networking, that is to say, that technical solution of the embodiment of the present invention is suitable for radio frequency remote unit RRU and passes through certainly
The same baseband board of one BBU of two optical ports while access or the different baseband boards or difference of same BBU that body has
Several situations of different baseband boards of BBU.

In Fig. 1~Fig. 3 examples, the service processing board of baseband processing unit BBU is CCU and BPU.Wherein CCU is master control
Clock board, BPU are baseband board.
It should be noted that for the scene across baseband board annular networking, the institute accessed on some RRU in RRU rings is useful
Family, same moment are only handled by baseband board, which is defined as the main baseband board of the RRU, other one on RRU looped networks
The baseband board in a direction is referred to as standby baseband board.
Above-mentioned different types of networking mode so that baseband board is different to the processing procedure of cell with user context data,
Therefore, when traffic failure occurs in RRU, the fault handling method suitable for current networking mode should be used to be handled, with
Just ensure that fault handling method most can rapidly release traffic failure.The purpose of technical solution of the embodiment of the present invention aiming at
Above-mentioned different types of networking mode, provides applicable fault handling method respectively.Skill of the embodiment of the present invention is described in detail below
Art scheme.
Shown in Figure 4, the method for processing business that the embodiment of the present invention proposes includes：
S401, two interfaces of Remote Radio Unit is controlled to carry out main and standby competition, distinguishes main interface and standby interface；
Specifically, generally there are two optical ports by RRU.RRU main light ports (main interface) are the optical port of RRU first line of a couplet BBU.RRU from this
Optical port unloads downlink I/Q data and is sent to antenna opening, the uplink I/Q data from antenna is multiplexed and is sent to main base band from the optical port
Plate.Another optical port that RRU spare optical ports (standby interface) are RRU, the main business relaying for playing the RRU ring second lines of a couplet each RRU in direction are made
With, the service backup scene that technical solution of the embodiment of the present invention is applied also play a part of transmit this RRU backup traffic.
The embodiment of the present invention is set, and in BBU sides, the good ring-network topology relationship of configured in advance specifically includes：RRU is in RRU looped networks
In position, RRU looped network head and the tail base station number, baseband board number and optical port number, cell to be established in RRU on baseband board
Information etc.." head " of RRU looped networks i.e. it is expected under normal circumstances under normal circumstances by the optical port where desired main baseband board, " tail "
Standby baseband board where optical port.Downlink business flow direction (i.e. base station to service route of eating dishes without rice or wine) is from RRU ring heads under normal circumstances
To the corresponding direction of ring tail.
The embodiment of the present invention is also set, after RRU electrifying startups, two IR mouthfuls of processes there are main and standby competition.RRU is powered on
Two optical port states of self-test, for there is the optical port of (LOP) not in place, unglazed (LOS), Frame Alignment Loss (LOF), work shape
State is abnormal, it is impossible to be operated in the state of main light port.If two optical port states are all normal, IR mouthfuls of operating modes are configured to the first line of a couplet
The IR mouths of optical port have priority, preferentially carry out subsequent version updating, latency measurement and configuration, parameter configuration and cell and establish
Etc. links, and establish cell be main plot.
Optical port state under normal circumstances IR mouthfuls of main and standby competition flows as shown in figure 5, noticing that this flow chart does not account for version
The link of inconsistent upgrading, after the optical port of different editions upgrades to same version, RRU will restart, and subsequent active and standby optical port is competing
It is consistent with Fig. 5 to strive flow.First line of a couplet optical port has priority in IR mouthfuls of main and standby competitions, and RRU after the power is turned on if without working in time
In the state that first line of a couplet optical port is main light port, cascade optical port, which is delayed T1 seconds, waits for it to complete corresponding work, the time setting of T1
Ensure that RRU can access all links that BBU completes secondary IP address and is assigned to cell foundation from some optical port under normal circumstances, and
And the time should not it is long with ensure system provide business speed.
S402, connection relation and preset service backup method according to the Remote Radio Unit and baseband board,
In normal course of operation and/or when traffic failure occurs for the main interface, service backup is carried out to the Remote Radio Unit
Processing；Wherein described preset service backup method includes being set according to the connection relation of Remote Radio Unit and baseband board
Service backup method.
Specifically, main and standby competition is completed in RRU control optical ports, after distinguishing main light port (interface) and spare optical port (interface),
For the ease of subsequent processing, the expectation flow direction and service backup mode of RRU looped networks need to configure optical port corresponding to RRU.RRU's
It is expected that IR mouthfuls of access (would know that with reference to the configuration of RRU looped networks) is " first line of a couplet optical port ", another optical port of RRU is " cascade at this time
Optical port ".In addition, specific works pattern also needs to differentiated service backup mode.
Caused by aforementioned traffic failure is RRU annular networking dysfunctions, as some RRU is detected in main light port in looped network
(LOP)/unglazed (LOS)/Frame Alignment Loss (LOF) alarm not in place receives optical fiber switching control word from main light port.This hair
The preset service backup mode that there is provided of optical port that bright embodiment is RRU includes cold standby, warm standby, three kinds hot standby.Wherein, cold standby is not
The cell context and user's context of RRU are backed up, RRU is restarted when a failure occurs, deletes former cell and former cell
Interior user's context；Under warm standby mode, when traffic failure occur in RRU main light ports, spare optical port takes over key light port service, it is not necessary to
Cell is rebuild again, but deletes the user's context in former cell；Under hot standby mode, in normal course of operation, use of backing up in realtime
Family context, when traffic failure occur in RRU main light ports, spare optical port takes over key light port service, you can to restore business.
The service backup mode for IR mouthfuls of configurations, IR optical ports can be divided into according to embodiments of the present invention：General mode optical port,
Cascade mode optical port, active-standby mode optical port, load sharing pattern optical port, cold standby looped network first line of a couplet optical port, cold standby looped network cascade optical port,
Warm standby/hot standby first line of a couplet optical port, warm standby/hot standby cascade optical port one kind therein.
When traffic failure occurs for the main light port of RRU, the embodiment of the present invention accesses the connection mode of BBU according to main light port,
Using the service backup method in advance for main light port configuration, service backup processing is carried out to RRU.For example, it is assumed that it is a certain in advance
The main light port of RRU is configured with warm standby service backup method, then when traffic failure occurs for the main light port, using warm standby method to this
RRU carries out service backup processing, and the RRU is made to restore regular traffic again.
It should be noted that in embodiments of the present invention, there are two optical ports, respectively main light port and spare optical port for RRU tools.
Under normal circumstances, service communication is realized by main light port, and when main light port traffic failure occurs and leads to service disconnection, the present invention is real
The active and standby optical port for applying example execution RRU switches processing, takes over main light port by spare optical port and realizes service communication, restores service communication.
Remote Radio Unit in technical solution of the embodiment of the present invention can access system in many ways, work as remote radio
When traffic failure occurs in unit, according to the concrete mode of Remote Radio Unit access system, with reference to preset service backup
Method carries out service backup, and backup mode more suits system structure, therefore can meet the service backup field of different networking modes
Scape, service backup efficiency is more secure, conducive to call drop is prevented, promotes user experience.
Optionally, in another embodiment of the present invention, after main interface and standby interface is distinguished, this method further includes：
Main plot is established for the main interface and establishes standby cell for the standby interface；
When the standby cell normal work, the downlink common control channel unrelated with user is established for the standby cell,
And generate corresponding downlink data.
Specifically, for the scene across baseband board annular networking, between not support plate in the case of base band resource pool, RRU
Some RRU corresponds to the cell established in main baseband board in ring, is main plot；In order to reduce the conversation loss time, in standby baseband board
Interior needs establish a cell simultaneously, this cell is referred to as standby cell.
The embodiment of the present invention is set, and for the scene across baseband board annular networking, the baseband board for main interface connection is established
Cell for main plot, the cell established of baseband board for being standby interface connection is standby cell.
Also, when the standby cell operation that inspection institute establishes is normal, the embodiment of the present invention is that the standby cell of normal work is built
The vertical downlink common control channel unrelated with user, and generate corresponding downlink data.It is appreciated that based on treated
Standby cell has been that have communication channel, has been able to realize the cell of service communication, this is for cell and unique area of main plot
It is not exactly without specific customer service in standby cell.When main plot is broken down, customer service is transferred directly to standby small
Area, you can continue business, prevent from being that standby cell creates down control channel and wastes time again when needing transfer service, influence
Customer service continuity.
It, can be by active and standby interface inverting, by standby interface when traffic failure occurs for RRU main interfaces based on above-mentioned processing
The main plot that standby cell takes over main interface carries out service communication.
Optionally, in another embodiment of the present invention, the company according to the Remote Radio Unit and baseband board
Relationship and preset service backup method are connect, in normal course of operation and/or when traffic failure occurs for the main interface,
Service backup processing is carried out to the Remote Radio Unit, including：
Control the main plot of the baseband processing unit deletion Remote Radio Unit being connect with the Remote Radio Unit,

Relationship and preset service backup method are connect, in normal course of operation and/or when traffic failure occurs for the main interface,
Service backup processing is carried out to the Remote Radio Unit, including：
If the baseband board that the main interface is connected is different from the baseband board that the standby interface is connected, described in control
The baseband processing unit that main interface is connected is backed up in realtime to be connected with the associated user's context in the main plot to the standby interface
The baseband processing unit connect, and by the user's context of backup and the standby cell association；
When traffic failure occurs for the main interface, to the main interface and the standby interface and the main interface with
The parameter configuration of the standby interface carries out switching processing respectively, obtains resetting main interface and the standby interface of resetting；
Specifically, the service backup method that the embodiment of the present invention proposes, referred to as hot standby.In hot spare method, Base-Band Processing
Always there are the cell context of traffic failure RRU and associated user's context in unit, and the base of active and standby optical port connection
Tape handling plate is if it is different, then need user's context of backing up in realtime, when RRU main light ports (main interface) break down, by master
Spare optical port is switched, and business is undertaken by the backup cell and backup user's context of the main plot of spare optical port backup.
When there is traffic failure in RRU main light ports, and spare optical port (standby interface) is normal, the embodiment of the present invention by main light port and
Spare optical port is switched, while the parameter configuration of main light port and spare optical port is switched.After switching, main light port originally

Solution, due in hot standby mode, spare optical port is backed up in realtime the user's context of main light port, therefore the resetting key light after switching
Mouthful, it can continue directly to undertake business.
Since original RRU cell and user's context are all based on the baseband board setting of the original main light port connections of RRU
, therefore, after RRU main light ports and spare optical port are switched, to be with the baseband board that former main light port is connect according to resetting main light port
It is no identical, optionally delete the cell and user's context of original RRU.
If the baseband board that the resetting main interface is connected is different from the baseband board that the main interface is connected, control

The standby small area carrier customer service of the resetting main interface, and when the service failure recovery of the standby interface of the resetting,
Standby cell is established for the standby interface of the resetting.
In this case, back-up processing process is as shown in Figure 9.When user (UE) accesses, master clock plate is built in this plate
Vertical user's context also establishes user's context and backup user's context in main baseband board respectively simultaneously with active/standby cell association
To after standby baseband board, when RRU main light port traffic failures, initiated by the RRU and finally completed by the control of master clock plate active and standby
Optical port is switched and standby cell is upgraded to main plot whole process.
If the baseband board that the resetting main interface is connected is different from the baseband board that the main interface is connected, and is located at
Different baseband processing units, then control that the baseband processing unit that the main interface connected deletes the main plot and the master is small
The associated user's context in area controls the standby small area carrier customer service of the resetting main interface, and when the resetting
During the service failure recovery of standby interface, standby cell is established for the standby interface of the resetting.
In this case, back-up processing process is as shown in Figure 10, when user (UE) access, the base that former main light port is connected
Tape handling unit in this equipment other than establishing user's context and being associated with main plot, also by privately owned X2 message in original
Backup user's context and and former standby cell association in the baseband processing unit that spare optical port is connected.When the event of RRU key lights port service
Barrier is initiated by the RRU and is finally switched by the active and standby optical port of webmaster OMC intervention completions and be upgraded to main plot whole process for cell.
It should be noted that the base band that the baseband board connected for the resetting main interface is connect with the main interface
The identical situation of plate, due in hot standby mode, retaining always in the master clock plate where main baseband board and main baseband board small
Area's context and user's context therefore it may only be necessary to which active and standby optical port, which is switched, can continue business procedure, do not need to carry out cell
Or user's context deletion and back up in realtime.

The IP address that RRU optical ports are distributed in setting is private address, as it can be seen that each base of entire base station system only in baseband board
The assignable IP address range of band plate is identical, IP address is continuous, and each assignable IP address quantity of baseband board is：Baseband board branch
Hold the RRU maximum quantity * 2+ protection offsets of access.
If the access direction of RRU is from RRU rings tail to ring head, illustrate it is the normal access from main light port, at this time
Baseband board distributes IP address for RRU optical ports from small to large according to IP address；Otherwise explanation be reversely to access, at this time baseband board according to
IP address distributes IP address for RRU optical ports from big to small.For example baseband board supports that the RRU maximum numbers of access are 12, protection is inclined
Shifting amount is 10, and IP address range is 192.168.11~192.168.45, then first RRU normally accessed points in the baseband board
The address matched is 192.168.11, and first address of RRU distribution reversely accessed is 192.168.45.
According to the method described above, the IP address for distributing to same RRU differences optical port does not have identical situation appearance.
