Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
What Fig. 1 showed is the flow chart that radio frequency remoto module is managed maintenance, specifically may further comprise the steps:
The method of above-mentioned distribution site identifier has two kinds: unified distribution and inside of base station unified distribution in the wireless access network (RAN).
Unified distribution refers to and is the unique site identifier of each soft base station assigns in the wireless network in the wireless access network, and the RRU that belongs to same soft base station uses identical site identifier.
The inside of base station unified distribution refers to the unique site identifier of each soft base station assigns of managing same base station, and all RRU that belong to same service area are as a soft base station, and its site identifier is identical.When adopting this method, the site identifier in the network between different base station is distributed uncorrelated mutually.Because the base station that each base station is provided with in the time of can be by network planning numbering is discerned,, can determine RRU to be safeguarded by the site identifier in base station numbering and this base station so Operation ﹠ Maintenance System manages when safeguarding whole network.Described Operation ﹠ Maintenance System refers to LMT Local Maintenance Terminal (LMT, LocalMaintenance Terminal) system or system of operation maintenance center (OMC, Operation MaintenanceCenter).
Be connected to the distribution method of example explanation site identifier below with the network in the single base station shown in Figure 2.Four service areas of base band main control module condominium reason shown in Fig. 2, wherein RRU1, RRU2 and RRU3 cover a service area respectively, so each RRU constitutes a soft base station, SiteNum is configured to 1,2 and 3 respectively, and RRU1, RRU2 adopt the chain networking mode to link to each other with the base band main control module with RRU3.RRU4, RRU5 and RRU6 are common to cover a service area, so soft base station of the common formation of these three RRU, SiteNum is configured to 4, and RRU4, RRU5 adopt the ring-type networking mode to link to each other with the base band main control module with RRU6.
The described management maintenance that RRU is carried out comprises: inquiry, show the RRU current state, to the RRU software upgrade, operation such as reset.
Inquiry also shows that the method for RRU current state specifically may further comprise the steps:
A, Operation ﹠ Maintenance System show between the base station and/or the network connection layout between base station and the next stage RRU according to current network distribution situation.
The networking information in the wireless network between the base station and the networking information of each base station can only be kept at base band main control module place, and this moment, the OMC system obtained the network composition of base station to the base band main control module by sending instructions down; The base band main control module also can initiatively send to the OMC system with networking information and preserve, and then the network composition just can be known by the inquiry local data base in the OMC system.For the LMT system, then need to sign in to the base band main control module of base station, obtain the networking information of each base station.When the networking information in wireless network changes, upgrade the networking information of preserving in the OMC system, to guarantee the correctness of OMC information that system is preserved by the information configuration simultaneous operation between base station main control module and the OMC.
Networking information between the described base station be meant that the base station of wireless network is formed and the base station between connection relation information.The networking information of described each base station be meant that the RRU of each base station forms and RRU between connection relation information.
Operation ﹠ Maintenance System can adopt topological structure to show that the network between the RRU connects after knowing that network is formed.Wherein, topological structure shows two states: RRU hidden state and RRU deployed condition.The RRU hidden state only shows the base station that exists in the whole wireless network, in the time need further knowing the RRU group network topological structure of certain base station, can such as being arranged on other "+" symbol in this base station, enter the RRU deployed condition by clicking the expansion sign that is provided with for this base station.When the RRU deployed condition, the base station will show hiding sign such as "-" symbol, then can return the RRU hidden state by clicking to hide to identify.In the said process, click the expansion sign that is provided with for described base station, the networking information of this base station that the trigger action maintenance system is searched in the local data base to be preserved, and generate the next stage topology diagram of this base station according to networking information, specifically how generating topology diagram according to networking information is prior art.The keeper can know that the base station administers RRU number, the RRU networking relation between residing position and each RRU network connects from the next stage topology diagram of described base station.
Before the network connection layout showed with the RRU deployed condition, Operation ﹠ Maintenance System can also obtain the networking information of described base station in real time from the base band main control module, and connected according to the networking information display network of real-time acquisition.
A kind of topological structure expanded view such as Fig. 3 of base station shown in Figure 2.Each RRU among Fig. 3 can selectedly carry out move operation, after certain RRU is selected, Operation ﹠ Maintenance System determines to have with this RRU in the same base station the residing display position of RRU of same site identifier according to networking information, and indicating above-mentioned RRU with empty frame or anti-mode such as show, these RRU are carried out integral body in displayed map mobile.For example, RRU4, RRU5 and RRU6 have the same site identifier, so move simultaneously as a whole when mobile in the connection layout that shows.
Another kind of topological structure display mode such as Fig. 4 of base station shown in Figure 2 distinguish different RRU by the RRU title on each branch, connect but this display mode can't further show real topology.
B, Operation ﹠ Maintenance System issue the status poll instruction that carries site identifier, require to obtain the RRU state information with specified sites identifier.
For the LMT system, with the base band main control module of specified sites identifier respective base station set up communicate by letter after, the LMT system issues status poll and instructs to the base band main control module, by the corresponding relation of base band main control module according to site identifier of self preserving and RRU sign (RRU_ID), inquire the RRU that comprises under this site identifier, and issue a bar state query statement for each RRU.
For the OMC system, can after knowing which RRU is this site identifier comprise,, deliver to RRU earlier according to site identifier inquiry local data base via the base band main control module for each RRU under the site identifier issues a bar state query statement; Perhaps, OMC issues a status poll that comprises site identifier and instructs base band main control module to corresponding base station, after the base band main control module inquires the RRU that comprises under this site identifier, is respectively each RRU and issues a bar state query statement.
Connecting based on network shown in Figure 2, is 4 if the keeper specifies the site identifier of executing state query manipulation, and then RRU4, RRU5 and RRU6 will receive the status poll instruction.
In the said process,, also need carry the base station numbering in the status poll instruction that Operation ﹠ Maintenance System issues if in inside of base station unified distribution site identifier.
C, RRU report Operation ﹠ Maintenance System with oneself state information by the base band main control module after receiving the status poll instruction.
Described state information is meant the information that is used to indicate the RRU current state, and RRU is with report and alarm message when breaking down, and this alarm information comprises alarm numbering, alarm level, fault type, and the RRU sign that promptly breaks down of faulty equipment numbering.
In the practical application, RRU need dispose some ancillary equipment, puts such as electrical tilt antenna, tower etc.These ancillary equipment directly do not show on Operation ﹠ Maintenance System, thus be attached to described RRU for the management maintenance of these ancillary equipment, such as with the alarm information of ancillary equipment as the RRU alarm report.
D, Operation ﹠ Maintenance System are according to the state information that receives, at the network connection chart display RRU of current demonstration state, so that the keeper can in time grasp the situation of RRU.
Suppose RRU1 report and alarm message, with the example that is shown as of topological structure, when being in the RRU hidden state, Operation ﹠ Maintenance System will be on base station under the RRU1 display alarm sign and/or alarm level; When being in the RRU deployed condition, Operation ﹠ Maintenance System finds the position of RRU1 in the network connection layout according to site identifier and the RRU sign of RRU1, and this alarm identifier and/or alert level directly are presented on the RRU1 present position.
In the said process, Operation ﹠ Maintenance System is execution in step B and C completion status query manipulation only, and needn't show the state information of each RRU on the network connection layout intuitively, and also only execution in step A comes the display radio network of network to connect situation.
Identical to RRU software upgrade, method of operating such as reset with the query State operation, with Fig. 2 is example, keeper's appointment is 4 RRU software upgrade to site identifier, Operation ﹠ Maintenance System sends the software upgrade instruction that carries site identifier 4, be issued to RRU4, RRU5 and RRU6 by the base band main control module, RRU4, RRU5 and RRU6 receive behind the software upgrade instruction software upgrade synchronously.
By the above embodiments as seen, the method of this managing and maintaining radio frequency pull far module of the present invention, for the soft base station of each service area is provided with unique site identifier, Operation ﹠ Maintenance System is according to the RRU that sends instructions under the site identifier and safeguard to needs in advance, thus the serviceability of raising RRU.
