Description

A method for maintaining spare motherboards on base stations

technical field

The invention relates to the field of communication equipment, in particular to a method for maintaining a spare main board on a base station.

Background technique

In the third-generation mobile communication (3G) network, the baseband single board on the base station (NodeB) includes two single boards, the two single boards are mutual backup relationship, only one can work as the main main board at the same time, and the other One as a spare motherboard. If the active main board fails, the standby main board is switched to be the active main board under the control of the base station, and the original active main board becomes the standby main board. This process is called the active-standby switching process. The active main board and the standby main board are collectively referred to as the main board and the standby board.

Generally, many base stations are distributed in remote places, and radio network controllers (Radio network controller, RNC) are distributed in the central computer room. Through the IPOA (IP Over ATM) channel established between RNC and NodeB, maintenance operations such as analysis and problem location can be performed on the base station in the central computer room. The IPOA is a technology for transmitting IP data packets on an Asynchronous Transfer Mode (Asynchronous Transfer Mode, ATM) network.

As shown in Figure 1, the remote maintenance of the main motherboard on the base station from the personal computer (Personal Computer, PC) in the central computer room involves the following equipment: PC 101, network hub (HUB) 102, bandwidth and authentication manager (bandwidth and authentication manager, BAM) 103, RNC 104, NodeB 107. The RNC 104 has a main control board (main processor unit, MPU) 105 and a multiplexer (multiplexer, MUX) 106. On the NodeB 107, there are an active main board 108 and a standby main board 109. PC 101 is connected with BAM 103 and RNC 104 through network hub 102, and RNC 104 and NodeB 107 are connected through network 110. Among them, PC, HUB, BAM and RNC are in the central computer room.

The process of remotely maintaining the main motherboard on the base station from the PC in the central computer room is shown in Figure 2, with the following steps:

Step 201, an IP address is set on the PC; two IP addresses are respectively set on the BAM, the MPU, and the multiplexer (multiplexer, MUX); The above mentioned PC and BAM, BAM and MPU, MPU and MUX, MUX and main main board have IP addresses in the same network segment respectively.

For example, set the IP address of the PC to 10.161.73.92; there are dual network cards on the BAM, set the IP addresses of the BAM to 10.161.73.150 and 10.121.143.254; set the IP addresses of the MPU on the RNC to 10.121.143.208 and 192.1.1.254; set the RNC The IP addresses of the upper MUX are 192.1.1.1 and 12.13.13.254; set the same remote IP address of the active main board and the standby main board on the base station as 12.13.13.32.

In the above settings, PC and BAM, BAM and MPU, MPU and MUX, MUX and active and standby boards have IP addresses in the same network segment respectively.

Step 202, add a route to the active motherboard on the PC, BAM, and MPU; add a route back to the PC network segment on the MPU and MUX. For example,

Add routes on the PC as follows:

route add 12.13.13.0 mask 255.255.255.0 10.161.73.150-p

Among them, 12.13.13.0 is the destination address of the route. The destination address is the network segment where the remote IP address of the active and standby boards is located, 255.255.255.0 is the subnet mask, and 10.161.73.150 is the next-hop IP address. The meaning of the data in the following routes is the same as this one.

Add routing on BAM, as follows:

route add 12.13.13.0 mask 255.255.255.0 10.121.143.208-p

Add routes on the MPU as follows:

route add 12.13.13.0 mask 255.255.255.0 192.1.1.1-p

route add 10.161.73.0 mask 255.255.255.0 10.121.143.254-p

The second one is the return route, that is, the route back to the PC network segment.

Add a return route on the MUX, as follows:

route add 10.161.73.0 mask 255.255.255.0 192.1.1.254-p

Step 203, performing remote maintenance operations on the active mainboard from the PC.

Because the network segment of the external network port of the PC is the same as that of the BAM, the PC can access the BAM. The next hop address of the route on the PC is the IP address of the BAM, and the BAM can access the MPU through the internal network port address, so the PC can access the MPU through the BAM. The MPU has two IP addresses, one is in the same network segment of the internal network port as the BAM, and the other is in the same network segment as the MUX, so the MPU can access the MUX, so that the PC can access the MUX through the route on the BAM. Two IP addresses are also configured on the MUX, one is on the same network segment as the MPU, and the other is on the same network segment as the main board on the NodeB, so that the PC can further access the main board through the route on the MPU.

After the communication between the PC and the main board is realized, maintenance operations such as analysis and fault location can be performed on the main board.

Since the active mainboard and the standby mainboard are required to support active-standby switchover, the active mainboard and the standby mainboard have the same IP address, including the remote IP address and the near-end IP address. This objectively limits the inability to maintain the spare motherboard from a remote location. Generally, the method for maintaining the spare main board is that the staff perform maintenance on the base station through a serial interface. This method requires staff to travel long distances to reach the location of the base station, which is very inconvenient, and it is easy to delay the time for maintaining the spare motherboard, which may cause irreparable losses.

Contents of the invention

In view of this, in order to overcome the above disadvantages, the present invention proposes a method for maintaining a spare mainboard on a base station, the purpose of which is to perform remote maintenance on the spare mainboard.

According to above-mentioned purpose, the present invention provides a kind of method for maintaining spare motherboard on the base station, comprising the following steps:

A. Set an IP address on the maintenance terminal; set two IP addresses on the bandwidth and authentication manager BAM, the main control board MPU, and the multiplexer MUX respectively; set the same remote terminal IP address; on the main main board and the standby main board, respectively set the same network segment and different main and standby communication IP addresses; the maintenance terminal and BAM, BAM and MPU, MPU and MUX, MUX and main and standby boards, have IP addresses in the same network segment respectively;

B. Add a route to the network segment where the remote IP is located on the maintenance terminal, BAM, and MPU; add a route to the network segment where the active and standby communication IP addresses are located on the MUX; each on the MPU and MUX Add a route to the network segment where the maintenance terminal is located;

C. The maintenance terminal controls the main board to send a request to add a route to the network segment where the maintenance terminal IP is located by accessing the main board; the backup board establishes a route to the network segment where the maintenance terminal IP is located on the backup board according to the request routing;

D. The maintenance terminal accesses the standby motherboard through the settings in the above steps A, B, and C, and performs remote maintenance operations on the standby motherboard.

The above technical solution may further include the following steps: performing remote maintenance operations on the main main board.

The maintenance terminal is a personal computer PC.

The configuration of a route added on the MUX to the network segment where the main and standby communication IP addresses are located is as follows: the target address is the main and standby communication IP address, and the next hop is the main main board.

The configuration of a route to the network segment where the IP address of the maintenance terminal is established on the standby main board is configured as follows: the target address is the network segment where the IP address of the maintenance terminal is located, and the next hop is the active main board.

It can be seen from the above technical solution that the present invention realizes the access of the maintenance terminal to the standby main board by adding the main and standby communication IP addresses on the main and standby boards and related routing settings, so that users can remotely log in to the standby board in the central computer room. Mainboard, the problem location, debugging, information collection and analysis of the standby mainboard are carried out at the remote end, without the need for users to carry equipment to the location of the base station for near-end maintenance, which saves manpower, material and financial resources, especially time.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

As shown in Figure 3, the flow process of the present invention includes the following steps:

Step 301, set an IP address on the maintenance terminal; set two IP addresses on the BAM, MPU, and MUX respectively; set the same remote IP address on the main board and the backup board of the base station; Mainboards are set with different IP addresses for active and standby communication, and the two IP addresses for active and standby communication are in the same network segment; the maintenance terminal and BAM, BAM and MPU, MPU and MUX, and MUX and the main and IP address of the segment.

The maintenance terminal can be a PC, a server, etc. Here, a PC is taken as an example. For example, set the IP address of the PC to 10.161.73.92; there are dual network cards on the BAM, set the IP addresses of the BAM to 10.161.73.150 and 10.121.143.254; set the IP addresses of the MPU on the RNC to 10.121.143.208 and 192.1.1.254; set the RNC The IP addresses of the upper MUX are 192.1.1.1 and 12.13.13.254; set the same remote IP address as 12.13.13.32 and 17.21.3.3 as the remote IP address of the active main board and the backup main board on the base station. In the above settings, PC and BAM, BAM and MPU, MPU and MUX, MUX and active and standby boards have IP addresses in the same network segment respectively.

Set the active and standby communication IP addresses of the active mainboard on the active mainboard to: 1x.xx.xx.10, where x represents any number from 0 to 9; set the active and standby communication IP addresses of the standby mainboard on the standby mainboard to: 1x.xx.xx.11, these two IP addresses are in the same network segment. The active main board and the standby main board can communicate with each other through the active and standby communication network ports.

The IP address set above is only an embodiment of the present invention, and the protection of the present invention is not limited to the above IP address.

Step 302: Add a route to the network segment where the remote IP address of the active and standby boards is located on the PC, BAM, and MPU; add a route to the network segment where the active and standby communication IP addresses are located on the MUX; Add a route back to the network segment where the maintenance terminal is located on each MUX. For example,

Add routes on the PC as follows:

route add 12.13.13.0 mask 255.255.255.0 10.161.73.150-p

Add routing on BAM, as follows:

route add 12.13.13.0 mask 255.255.255.0 10.121.143.208-p

Add routes on the MPU as follows:

route add 12.13.13.0 mask 255.255.255.0 192.1.1.1-p

route add 10.161.73.0 mask 255.255.255.0 10.121.143.254-p

The second one is the return route.

Add routing on MUX, as follows:

route add 1x.xx.xx.0 mask 255.255.255.0 12.13.13.32-p

route add 10.161.73.0 mask 255.255.255.0 192.1.1.254-p

Wherein the first route is newly added by the present invention, and its target address is the primary and secondary communication IP address, and the next hop is the primary main board; the second route is the return route.

Step 303, sending a request to add a route to the network segment where the IP of the maintenance terminal is located from the active main board to the standby main board; establishing a route to the network segment where the IP of the maintenance terminal is located on the standby main board.

The PC accesses the active mainboard, and controls the active mainboard to send a request for adding a route from the active mainboard to the standby mainboard. After receiving the request, the standby mainboard implements the operation of adding a route on the standby mainboard through message processing. The destination address of the route is the network segment where the PC is located, and the next-hop IP address is the active mainboard's main-standby communication IP address, for example , execute the following command:

route add 10.161.73.0 mask 255.255.255.0 1x.xx.xx.10-p

Step 304, performing a remote maintenance operation on the standby main board.

Through the above settings, the communication from the PC to the spare motherboard has been realized, and the realization process will be explained below. Because the PC can access the standby mainboard, maintenance operations such as analysis and fault location can be performed on the standby mainboard from the PC.

In the following, the principle of each step of the present invention and the realized functions will be fully described, and the process of realizing PC access to the spare main board will be explained.

Through the setting of step 301 and step 302, the communication from the PC to the main main board is realized. The principle is as follows: because the PC and BAM have the same network segment, the PC can access the BAM. The next hop address of the route on the PC is the IP address of the BAM, and the BAM can access the MPU through the internal network port address, so the PC can access the MPU through the BAM. The MPU has two IP addresses, one is in the same network segment of the internal network port as the BAM, and the other is in the same network segment as the MUX, so the MPU can access the MUX, so that the PC can access the MUX through the route on the BAM. Two IP addresses are also configured on the MUX, one is on the same network segment as the MPU, and the other is on the same network segment as the main board on the NodeB, so that the PC can further access the main board through the route on the MPU. At this point, the communication from the PC to the main board has been established, and remote maintenance can be performed on the main board at any time.

Since the active main board and the standby main board have the active and standby communication IP addresses on the same network segment, and in step 302, the network segment where the target address is the active and standby communication IP address, and the route of the next hop for the active main board is added on the MUX, So the packets from the PC go through the main board to the backup board. However, only based on the above settings, the data packets sent to the standby mainboard cannot determine its own return route. Therefore, it is necessary to add a route back to the network segment where the PC is located on the standby mainboard. The next hop of this route is the active mainboard and the destination address. for PC. Before this route is added, the standby mainboard cannot be maintained, and of course it is impossible to directly add a route on the standby mainboard, so it is necessary to send a request for adding a route to the standby mainboard through the active mainboard. The active mainboard sends a request message to the standby mainboard through the active and standby communication IP addresses, and the standby mainboard receives the message, and through message processing, the operation of adding routing can be realized.

So far, the communication from the PC in the central computer room to the standby motherboard on the base station has been realized, so that remote maintenance operations can be performed on the standby motherboard.

The present invention can not only be used for the maintenance of the spare mainboard on the 3G base station, but also can be used for the maintenance of the spare mainboard on the base stations of other networks such as Global System for Mobile Communication (GSM).

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
