Description

Self-discovery method, device and system for distributed base stations

technical field

The present invention relates to the communication field, in particular to a self-discovery method, device and system for distributed base stations.

Background technique

The self-discovery of distributed base stations means that during the opening process of the base station, the baseband unit (Bandwidth Based Unit, referred to as BBU) or radio frequency remote unit (Radio Remote Unit, referred to as RRU) finds that it already exists on the network. The performance of "already existing" mainly means that the BBU or RRU unit has obtained some parameters on the network, such as the network management IP address, subnet mask and gateway IP. The purpose of the distributed base station self-discovery is to enable the network management to find the base station in the network and establish a connection with it.

At present, for distributed base stations based on BBU+RRU architecture, according to traditional network management methods, engineers must manually perform basic configuration on the base station side and network management side. The basic configuration parameters can include: base station IP address, network management IP address, Gateway IP address and other parameters that allow the base station to function. When there is a requirement for RRU cascading, the RRU and the connection status of the RRU must be manually added on the network management, that is, the topology structure, so that the BBU can know the existence of the RRU and establish message communication with the RRU so that the RRU can work normally.

The above-mentioned traditional management methods have the following problems:

The configuration process is complicated: the basic configuration needs to be performed on the base station side and the network management side at the same time;

Parameter configuration is cumbersome: the data configured on the base station side and the network management side are based on planning data, and manual input is required;

The configuration process is error-prone: the configuration process on the base station side and the network management side cannot guarantee that manual input parameters will not be wrong, and when some key parameter configurations are inconsistent between the base station side and the network management side, it may cause major failures.

Aiming at the problem that distributed base stations need to be manually configured in the related art, no effective solution has been proposed yet.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Embodiment one

An embodiment of the present invention provides a self-discovery method for a distributed base station. FIG. 1 is a flowchart of a self-discovery method for a distributed base station according to Embodiment 1 of the present invention. As shown in FIG. 1 , the method includes:

Step S102, the BBU obtains unconfigured BBU single board information according to its single board configuration state and single board insertion state;

Step S104, when the BBU detects an unconfigured RRU that is connected to the BBU through a loopback test, collects unconfigured RRU single board information;

Step S106, sending the unconfigured BBU board information and the unconfigured RRU board information to a network manager for the network manager to configure the distributed base station.

In the prior art, distributed base stations need to be manually configured, and the configuration process is complex, parameter configuration is cumbersome, and the configuration process is prone to errors. Through the above steps, the information about unconfigured BBU boards and unconfigured RRU boards can be self-discovered, and the information about unconfigured BBU boards and unconfigured RRU boards can be sent to the NMS, so that the NMS can self-discover the BBU and RRU configuration, which provides the possibility of technical implementation for solving the problems in related technologies.

For example, the board configuration status of the BBU can be obtained by querying the configuration status data of the BBU, and the board status of the BBU can be obtained through the board heartbeat message of the BBU, or can be obtained by querying the board status data of the BBU Obtain the state of the single board of the BBU, and then obtain the information of the unconfigured BBU single board by comparing the state of the single board with the corresponding state of the single board configuration. Of course, it is also possible to use different methods to obtain the board configuration status and board insertion status of the BBU according to the development of technology and other factors. Configure BBU board information, the example in this paragraph is just a preferred example, not limited thereto.

The BBU can also detect whether the BBU is connected to the RRU through a loopback test. If the BBU is connected to the RRU and the RRU is in an unconfigured state, the BBU determines that the RRU is unconfigured RRU. In this embodiment, it is considered that the loopback test is a better way to detect unconfigured RRUs, and in other embodiments, it is also possible to detect unconfigured RRUs according to other test methods.

If the unconfigured RRU board information is collected, after that, the self-organizing network (Self-Organizing Networks, SON) agent on the RRU side can also send the unconfigured RRU board information to all The SON manager of the BBU, the SON manager can also update the route and topology of the corresponding RRU according to the information of the unconfigured RRU single board. In the prior art, if the topology structure of the RRU changes, the original configuration needs to be modified on the network management. In this embodiment, it is considered that the BBU can automatically update the routing and topology of the corresponding RRU. In other embodiments, the BBU can also automatically update other attributes similar to routing and topology of the RRU according to the information of the unconfigured RRU board . In addition, the SON agent on the RRU side and the SON agent on the BBU side may also be implemented by other modules or devices in other embodiments.

Before the BBU detects an unconfigured RRU that is connected to the BBU through a loopback test, it can also detect the synchronization status of the interface rate between the BBU and the RRU. When the BBU and the RRU are detected When the interface rates between the RRUs are in an asynchronous state, the RRUs may sequentially configure the interface rates as the rates of each optical port in the optical port rate capability set until the interface rates between the RRU and the BBU are consistent. In the prior art, the interface rate between the BBU and the RRU is manually configured, but in this embodiment, the RRU adaptively matches the interface rate of the BBU. In other embodiments, the rate of the interface between the RRU and the BBU may also be automatically matched in other ways.

If the RRU adapts to the interface rate of the BBU, then the RRU can configure the interface rate of the RRU from the highest capability level in the optical port rate capability set, and cycle through until the interface rate between the RRU and the BBU The interface rate is the same. In other embodiments, it is also possible to traverse only once, or traverse multiple times, instead of using a loop traversal manner. Of course, the interface rate of the RRU can also be configured from the lowest capability level, and the optical port rate can also be obtained from other optical port rate data sources for configuration.

Embodiment four

4 is a flow chart of a self-discovery method for a distributed base station according to Embodiment 4 of the present invention. The distributed base station includes a BBU and an RRU, wherein a SON manager (SON Manager) and a The BBU-side SON agent (SONAgent) residing in the internal unit of the BBU side and the RRU-side SON Agent residing in the RRU side. SON is a new network management concept in the third-generation mobile communication Long Term Evolution (LTE) system. Its core idea is to realize some autonomous functions of the wireless network, reduce manual intervention, and reduce operator operating costs. Improve operational efficiency and improve user experience. As shown in Figure 4, the method includes the following steps:

In step S402, the SON Manager is initialized.

After the SON Manager receives the BBU power-on message, the SON Manager performs initialization preparations, including: obtaining the configuration status of each board of the internal unit on the BBU side, enabling the timer for periodically querying the status of the board, and enabling the periodic detection of unconfigured single boards. board timer.

Wherein, the single board configuration status is obtained by querying configuration status data. SON Manager queries the single board configuration status of the BBU from the database configuration table, that is, the configuration status data, through the subrack management module of the BBU. When the database configuration table in the subrack management module changes, the subrack management module notifies the SON Manager through the trigger of the registry.

In step S404, the SON Manager acquires information about unconfigured BBU single boards.

When the timer for periodically querying the status of the boards expires, SON Manage obtains the status of the boards of the BBU from the BBU. Specifically, there are two ways to obtain the status of the board: one way is that the board reports the status of the board through heartbeat, that is, if the SON Manager can receive the heartbeat message of the board reported by the heartbeat reporting module of the BBU , judge whether the board is working normally according to the received heartbeat message, and then obtain the status of the board; another way is to obtain the status of the board through the message provided by the subrack management module of the BBU. Specifically, it is By periodically querying the interface of the subrack management module, that is, querying the status data of the subracks through the subrack management module, the status of all the boards of the internal units on the BBU side can be obtained.

When the SON Manager receives the response message from the subrack management module or the heartbeat reporting module, that is, after receiving the status of the board, it updates the status of the internal board on the BBU side, and compares the status of the board with the corresponding The configuration status of the board can be used to obtain the unconfigured information of the board. If the board has not obtained the hardware information, the hardware information is queried through the hardware information reporting module to obtain the hardware information of the BBU.

Step S406, performing adaptive optical port rate matching.

When the SONAgent of the BBU receives the BBU power-on message, it starts the timer for periodically obtaining the unconfigured RRU, and performs adaptive optical port rate matching. The SON Agent on the BBU side obtains the optical port rate list of the internal units on the BBU side, reports the unconfigured RRU and the optical port rate information of the internal units on the BBU side to the SON Manager, and performs self-adaptive drive on the optical port rate periodically, and the optical port rate information of the first-level RRU Port rate matching. The specific process of adaptive optical port rate matching between the SONAgent on the BBU side and the SONAgent on the RRU side is explained in detail in Embodiment 5, and will not be repeated here.

Step S408, acquiring information about an unconfigured RRU board.

The SONAgent on the BBU side periodically obtains information about all unconfigured RRU boards connected to the BBU. When the timer for periodically obtaining unconfigured RRUs expires, the SON Agent on the BBU side interacts with the SON Agents on each RRU side to obtain the configuration information of the RRUs. Specifically, after receiving the request from the SON Manager to query the RRU configuration, the SON Agent on the BBU side judges whether the optical port is configured as a ring or whether the actual connection is a ring, and judges whether the RRU is unconfigured through the detection of an unconfigured RRU. If If the RRU is unconfigured, obtain the information about the unconfigured RRU board.

Among them, the detection of unconfigured RRU is based on the result of the loop test (LoopTest) in the logic hardware control word to check whether the links of the RRUs of all levels connected to each optical port in the BBU board are connected and disconnected, and whether the actual link of the optical port is into a ring. If the RRUID is 255 and the LoopTest result is passable, then the RRU can be considered connected but not configured; if the RRU ID is 255 and the LoopTest result is not passable, then the RRU is considered not connected, so self-discovery is not required. Among them, an RRU ID of 255 indicates that the RRU is in an unconfigured state, that is to say, when the BBU manages the RRU ID, the RRU with an initial default RRU ID of 255 is in an unconfigured state.

Step S410, reporting the information of the unconfigured RRU board.

The SON Agent on the BBU side reports the unconfigured RRU board information to the SON Manager. The SON Agent on the RRU side reports the unconfigured RRU board information to the SON Manager through the SON Agent on the BBU side.

In step S412, the SON Manager processes the reported information.

After receiving the reported information, SON Manager allocates virtual RRU ID and updates topology and routing. Specifically, after receiving the message of unconfigured RRU single board information reported by the SONAgent on the BBU side, SONManager records the unconfigured RRU single board information, and sets the route and virtual RRU ID through the RRU ID management module.

Wherein, the virtual RRU ID is used to uniquely identify the address of the RRU on the communication network, and the management of the virtual RRU ID is mainly reflected in the management of the virtual RRU ID state table. After receiving the unconfigured RRU message reported by the SON Agent on the BBU side, compare the result of this report with the result of the last report. If the RRU reported last time is not in the list reported this time, it means that the RRU has been configured or the RRU has been unplugged. The corresponding RRU ID needs to be deleted. If the RRU reported this time is not in the list discovered last time, it means that the RRU is newly discovered, and an RRU ID needs to be added.

In step S414, the SON Manager reports unconfigured BBU single board information and unconfigured RRU single board information to the network manager.

When SON Manager receives the periodic reporting timer message, it collects unconfigured BBU single board information and unconfigured RRU single board information that have not been configured and hardware information has been obtained through the BBU configuration information reporting module, and report it to the webmaster.

Specifically, SON Manager reports unconfigured board information to the network management through ftp, which is divided into three steps: 1. SONManager has discovered unconfigured BBU single boards and unconfigured RRUs, and has obtained related unconfigured BBU single board information and unconfigured RRU board information; 2. SON Manager saves unconfigured BBU single board information and unconfigured RRU single board information in .xml format and sends them to the corresponding ftp path; 3. Network management obtains unconfigured BBU single board information and unconfigured RRU board information.

In the above steps, S402 and S404 are executed successively, and S406 and S408 are also executed successively, but S402, S404 and S406 and S408 can be executed simultaneously or successively. In short, the relationship between the two is parallel.

Embodiment five

Fig. 5 is the flow chart of RRU rate adaptation of the fifth embodiment of the present invention. Before the SON Manager establishes a communication connection with the SON Agent residing on the RRU side, the rate matching between the BBU and the RRU must be completed, as shown in Fig. 5 , The rate adaptation process includes:

Step S502, power on and start the BBU and RRU.

Step S504, configuring parameters of default BBU and RRU interface rates.

Step S506, judging whether the interface is synchronized.

Determine whether the interface rate between the BBU and the RRU is synchronized with the interface rate of the peer device. The enabling condition of the RRU rate adaptation is to detect the synchronization state of the interface between the BBU and the RRU, and when it is detected that the BBU and the RRU are in an asynchronous state, the optical port rate adaptation process is started. If it is in the synchronization state, it means that the default interface rate matches the peer device interface rate, and there is no need to start the self-adaptation process, but the main process will continue to loop to detect the synchronization state, and execute step S506. If not synchronized, execute step S506. S508.

Step S508, configuring parameters of the first rate.

Specifically, when the RRU performs optical port rate adaptation, it starts to try from the highest capability level in the optical port rate capability set, and traverses in a loop. The optical interface unit on the BBU side is switched at T1 time, and the RRU is switched at 4T1 time, and T1 can be selected as (1~3) seconds. For the rate adaptation between the optical interface unit and the first-level RRU, the SONAgent process on the BBU side drives the Board Support Package (BSP for short) at a period of 30 seconds for optical port rate adaptation, and the BSP on the RRU also periodically Modify the logical optical port rate so that they can match. When BBU and RRU try a rate, configure the parameters of this rate as the current parameters of the device interface, and then judge the synchronization status between the device interfaces.

Step S510, judging whether the interface is synchronized.

Determine the synchronization status of the interface rate between the BBU and the RRU. In this step, if the synchronization state is normal, it means that the interface rate with the peer device has been synchronized, and step S506 is executed; otherwise, step S512 is executed.

Step S512, configuring parameters of the second rate.

Step S514, judging whether the interface is synchronized.

Judging the synchronization state of the interface, if the synchronization state is normal, it means that the interface rate with the peer device has been synchronized, then execute step S506, otherwise execute step S516.

Step S516, configuring the parameters of the third rate.

Step S518, judging whether the interface is synchronized.

If the synchronization state is normal, it means that the interface rate with the peer device has been synchronized, and then execute step S506, otherwise, it means that this self-adaptation is unsuccessful, and then go to step S520.

Step S520, judging whether a user's command to restart the adaptive process is received.

Output the result of adaptive failure to the system or directly to the user, judge whether to receive the user's order to restart the adaptive process, if not received, then wait and output the result of adaptive failure, execute step S522, If received, jump to step S508 to start the self-adaptation process.

Step S522, outputting a result that the self-adaptation is unsuccessful.
