Description

Method and device for self-configuration of base station

The present invention relates to the field of wireless communications, and in particular, to a method and an apparatus for self-configuration of a base station. Background technique

Currently, for a base station in a wireless network, the method of setting its IP parameters usually includes the following two types:

The first method is: accessing the base station from the near end through the debugging port of the base station, and setting the IP parameters provided by the base station to the OMC (Operation and Maintenance Center) using the LMT (Local Maintenance Terminal). Base station IP), the base station IP usually includes the IP address, subnet mask, gateway address, and DNS (Domain Name System) address used by the base station.

However, in the first method, using the LMT to set the base station IP at the near end increases the workload of the engineer, thereby reducing the efficiency of the parameter configuration process and increasing the error rate of the parameter configuration.

The second method is: Use dedicated DHCP (Dynamic Host Configuration)

Protocol, Dynamic Host Setup Protocol) Server, which allocates base station IP and OMC IP to the base station. The so-called OMC IP refers to the IP parameters of the OMC that is in communication connection with the base station, and usually includes the IP address, subnet mask, and gateway used by the OMC. The address and the DNS address are generally configured by the LMT to access the OMC at the near end. The base station is configured with the OMC IP to identify the packets sent by the corresponding OMC, and then perform maintenance operations on the base station.

However, in the second method, using the DHCP server to set the base station IP and OMC IP not only increases the operating load of the DHCP server, but also increases the workload of the engineering staff, thereby reducing the execution efficiency of the parameter configuration process and increasing the parameters. The configured error rate. For example, in fact In the inter-application, after the DHCP server configures a base station IP (called the base station IP A) for the base station, in the subsequent process, the OMC will again configure a base station IP (referred to as the base station IP B), the base station IP A and the base station for the base station. The IPB should be consistent. The communication link between the base station and the OMC can be established normally. If the two are inconsistent, the link between the base station and the OMC will be interrupted, thus affecting the overall performance of the wireless network. Summary of the invention

In order to improve the efficiency of the configuration process of the base station, and reduce the complexity of the configuration process and the configuration error rate, in the embodiment of the present invention, the LMT is no longer used to configure the parameters of the base station at the near end, nor The DHCP server is used to configure the parameters of the base station at the remote end. Instead, the OMC replaces the original DHCP server to provide a DHCP service for the base station. The mapping relationship between the identification information of the base station and the configuration parameters of the base station is pre-configured on the OMC. The so-called base station configuration parameters include the IP parameters of the base station (for example, the base station IP and the OMC IP), and the service configuration parameters including the base station; when the base station is powered on, it requests the OMC to obtain its IP parameters, and the OMC will according to the identification information of the base station. Sending the corresponding IP parameters to the base station, the base station performs IP-related configuration according to the obtained IP parameters. Further, after the IP-related configuration is successful, the base station establishes a communication link with the OMC, and continues to request the OMC to obtain service configuration parameters, OMC. The service configuration parameter set by the identifier information of the corresponding base station is sent to the base station, and the base station performs service related configuration according to the obtained service configuration parameter, and starts to enter a formal service processing flow.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , in the embodiment of the present invention, a wireless communication system includes a plurality of OMCs, and

The base station includes a transmitting unit 20, a receiving unit 21, and a processing unit 22, where

The sending unit 20 is configured to send, to the OMC side, a request message for acquiring an IP parameter of the base station, where the request message carries identifier information that can uniquely identify the base station, and a receiving unit 21, configured to receive the OMC. The IP parameter returned by the side corresponding to the identifier information is saved;

The processing unit 22 is configured to perform IP related configuration according to the obtained IP parameters.

The OMC includes a receiving unit 30, an obtaining unit 31, and a transmitting unit 32, where

The receiving unit 30 is configured to receive, by the base station, a request message for acquiring an IP parameter of the base station, where the request message carries identifier information that can uniquely identify the base station;

The obtaining unit 31 is configured to acquire an IP parameter that is pre-stored corresponding to the identifier information.

The sending unit 32 is configured to return the IP parameter to the base station, and enable the base station to perform IP related configuration according to the obtained IP parameter. Based on the foregoing technical solution, as shown in FIG. 4, in the embodiment of the present invention, the specific process of the base station acquiring the IP parameters from the OMC and performing related configuration is as follows:

Step 400: The base station sends a request message for acquiring the IP parameter of the base station to the OMC side of the operation and maintenance center, where the request message carries the identification information that can uniquely identify the base station.

In the embodiment of the present invention, the identifier information of the base station is set in multiple manners, including but not limited to: a MAC (Media Access Control) address of the base station, and a CC (Control and Clock Module) of the base station. The serial number of the board, the device identification of the base station, and so on.

On the other hand, since the base station has not established a communication link with the OMC side at this time, it is preferable that the base station sends the request message to the OMC side by using a broadcast message.

Step 410: The base station receives an IP parameter that is returned by the OMC side and is saved by the foregoing identifier information. Generally, since the base station sends a request message by using a broadcast message in step 400, correspondingly, there are multiple OMCs that receive the request message on the OMC side, and then the OMC that receives the request message is locally acquired. The IP parameters corresponding to the foregoing identification information (the IP parameters of the same base station are preset on multiple OMCs on the OMC side). Of course, if the relevant IP parameters are not saved on an OMC, the response may not be responded or a failure response may be returned. , will not repeat them here. If the base station receives the IP parameters that are saved by the at least two OMCs corresponding to the foregoing identifier information, preferably, the base station selects the first received IP parameters for subsequent configuration operations.

In the embodiment of the present invention, at least one base station IP (ie, the first IP parameter) used by the base station side and at least one OMC IP (ie, the second IP parameter) used by the OMC side are included in the IP parameters returned by any one of the OMCs. That is, the OMC can return multiple base station IPs and multiple OMC IPs to the base station for different application scenarios (eg, different network segments and different service modes). The base station can use different base station IP and OMC IP in different application scenarios. The OMCs corresponding to different OMC IPs may be the same or different, that is, the base station may select one of a plurality of different OMCs to establish a communication connection. Step 420: The base station performs IP related configuration according to the obtained IP parameters.

In this embodiment, when performing local IP configuration, the base station may select one base station IP and one OMC IP from the received IP parameters, and set a local IP address, a subnet mask, according to the selected base station IP. The gateway address and the domain name system DNS address, and the corresponding OMC's IP address, subnet mask, gateway address, and domain name system are determined according to the selected OMC IP.

Further, after completing the IP related configuration, the base station may establish a communication link with the OMC corresponding to the foregoing OMC IP. For example, it is assumed that the base station selects a base station IP and an OMC IP from the IP parameters sent by the OMC A for IP-related configuration, and after the configuration is completed, a communication link is established with the OMC B corresponding to the OMC IP, where OMC A And OMC B can be the same OMC, or it can be a different OMC.

After the base station establishes a communication link with the corresponding OMC, the service configuration parameter of the corresponding information of the base station can be obtained from the OMC. Preferably, the base station can obtain the service configuration parameter from the eNB through the unicast message, and obtain the service configuration parameter according to the unicast message. The service configuration parameters are configured for service related; wherein the so-called service configuration parameters include but are not limited to the following: communication parameters between the base station and the core network (eg, communication protocol, interface, message format, etc.), wireless parameters ( For example, the cell configuration information, the neighbor relationship information, and the like, after the service-related configuration is completed, the base station can establish a service link between the local and the OMC, and carry the related data service through the service link and perform corresponding processing. .

On the other hand, in this embodiment, the function of the DHCP server is implemented on the OMC, which can be used but is not limited to the following:

(1) Embed the currently announced DHCP Server software into the OMC, so that the OMC implements the DHCP Server function;

(2) By rewriting the OMC running source code, the OMC implements the DHCP Server function.

Further, referring to FIG. 1, if the base station and the OMC are in the same network segment, the base station may Directly communicate with the OMC. If the base station and the OMC are not in the same network segment, the base station can communicate with the OMC through the DHCP relay.

In the above embodiment, the OMC is used instead of the DHCP server in the system, so that the base station can avoid the DHCP server to obtain the IP parameters directly from the OMC. Since the DHCP server is no longer used, the network architecture of the system is effectively simplified, which not only saves the device. The resource also simplifies the IP configuration process of the base station, thereby improving the execution efficiency of the configuration process, reducing the execution complexity of the configuration process, and avoiding communication caused by the inconsistency between the IP parameters configured by the DHCP server and the IP parameters configured by the OMC. The link is interrupted, which effectively reduces the configuration error rate and improves system performance.

Based on the foregoing technical solution, as shown in FIG. 5, in the embodiment of the present invention, the specific process of the OMC providing the IP parameters to the base station and configuring the base station to perform related configuration is as follows:

Step 500: The OMC receives a request message sent by the base station to obtain an IP parameter of the base station, where the request message carries identifier information that can uniquely identify the base station.

At the same time as step 400, the identity information of the base station includes, but is not limited to, the MAC address of the base station, the sequence number of the CC board of the base station, the device identifier of the base station, and the like.

Step 510: The OMC obtains an IP parameter that is pre-stored corresponding to the foregoing identifier information.

Step 520: The OMC returns the obtained IP parameters to the base station, so that the base station performs IP related configuration according to the obtained IP parameters.

In the IP related configuration process, if the OMC IP address of the OMC is selected, that is, the base station selects to establish a communication link with the OMC, the OMC returns the identifier of the corresponding base station to the base station according to the request of the base station in the subsequent process. The pre-stored service configuration parameters enable the base station to perform service-related configuration according to the obtained service configuration parameters. In this way, the OMC can establish a service link with the base station after the base station completes the service-related configuration, and starts to perform service data transmission and processing. .

On the other hand, in this embodiment, the use of the DHCP Server protocol is implemented on the OMC (currently In the prior art, the OMC does not use such a protocol. Therefore, the OMC can communicate with the base station by using a DHCP format message, and the communication modes and operation steps involved in the related communication process need to be redesigned and negotiated. It has not been realized.

Further, if the OMC is in the same network segment as the base station, the OMC directly communicates with the base station. If the OMC and the base station are not in the same network segment, the OMC communicates with the base station through the DHCP relay.

In this embodiment, the mapping relationship between the identifier information of the base station and the configuration data of the base station (including the IP parameter and the service configuration parameter) is imported only on the OMC, and the OMC provides the IP parameter of the corresponding base station identification information to the base station according to the request of the base station, The base station completes the IP-related configuration and establishes a communication link with the OMC, and the OMC provides the service configuration parameter corresponding to the pre-stored base station identification information to the base station according to the request of the base station, so that the base station completes the service-related configuration and establishes a service with the OMC. The link simplifies the configuration process of the base station, improves the execution efficiency of the configuration process, reduces the execution complexity of the configuration process, reduces the configuration error rate, and efficiently completes the transmission self-establishment and service self-establishment of the base station.

Based on the above two embodiments, referring to FIG. 6, the above two embodiments are further described in detail through the interaction process between the base station and the OMC side:

Step 600: When the base station is powered on, the device sends a DHCP DISCOVER message to the OMC, and broadcasts the message to the OMC. The message carries the identifier information of the base station, which is called the identifier X.

Step 610: The OMC that receives the DHCP DISCOVER message (ie, the OMC instead of the DHCP server) obtains the IP parameters corresponding to the pre-stored IP (including the base station IP and the OMC IP, and adopts the DHCP OFFER (DHCP) according to the obtained identifier X. Provide) The message is returned to the base station.

Step 620: The base station first receives the DHCP OFFER message sent by the OMC A, where the DHCP OFFER message carries the IP parameter allocated by the OMC A for the base station. In an actual application, in step 620, if the base station receives the IP parameter assigned by the OMC A, it finds that the IP parameter has a configuration error, for example, the configuration parameter of the IP parameter is incomplete, the IP parameter cannot be read, and the like, the base station Returning to step 600, the DHCP DISCOVER message carrying the identifier X is sent to the OMC side to obtain the IP parameter pre-stored by the corresponding identifier X until the correct IP parameter is obtained. In this embodiment, only obtained in step 620. The correct IP parameters are taken as an example for explanation.

Step 630: The base station broadcasts a DHCP REQUEST message to the OMC side to notify the OMC side that the IP parameters sent by the OMC A are selected for IP related configuration.

Step 640: The OMC A replies with a DHCP ACK (DHCP acknowledgment) message to the base station, and the base station performs IP related configuration according to the IP parameters allocated by the OMC A.

At this point, the other OMCs reclaim the assigned IP parameters.

Further, in step 640, if the base station performs IP-related configuration according to the obtained IP parameters, it is found that the IP parameter has a configuration error, for example, the configuration parameter of the IP parameter is incomplete, the IP parameter cannot be read, and the like. Then, the base station will fall back to step 600, and then send a DHCP DISCOVER message carrying the identifier X to the OMC side to obtain the IP parameter pre-stored by the corresponding identifier X until the correct IP parameter is obtained. In this embodiment, only in step 640. The correct IP related configuration is described as an example.

Step 650: The base station sends a Trap message to the selected OMC B, where the Trap message also carries the identity information of the base station, that is, the identifier X. The Trap message is a warning message sent to the SNMP (Simple Network Management Protocol) administrator to notify the network status.

Assume that the base station, in the IP parameters returned by the OMC, the OMC IP of the selected OMC B, the base station establishes a communication link between the local and OMC B after completing the IP-related configuration, and sends a Trap message to the OMC B.

Step 660: The OMC B obtains the service configuration information corresponding to the pre-stored identifier X locally. After the Trap response message, the service configuration information is returned to the base station.

The service configuration information saved on the OMC corresponding to the same identifier information is the same. Therefore, the OMC B also serves as the DHCP server to provide the required service configuration information to the base station.

Step 670: The base station completes the service-related configuration according to the obtained service configuration information, that is, establishes a service link, and carries the corresponding service.

In the above embodiment, the OMC and the base station may use the public DHCP message format based on the DHCP protocol, and may also use the public DHCP message format by embedding the publicly used DHCP tool in the OMC based on the DHCP protocol. Further, all the DHCP-based interactions between the base station and the OMC are allowed to join the DHCP RELAY function, that is, when the base station and the OMC cross the network segment, the DHCP relay is used to forward the packet.

In summary, in the embodiment of the present invention, a DHCP Server protocol is implemented on the OMC, and a DHCP message is used to complete the IP related configuration of the base station, that is, the OMC is used instead of the DHCP server in the system, so that the base station is used. You can avoid the DHCP server to obtain IP parameters directly from the OMC, which simplifies the IP configuration process of the base station, improves the execution efficiency of the configuration process, reduces the execution complexity of the configuration process, and avoids the IP parameters and OMC configured by the DHCP server. The communication link is interrupted due to inconsistent IP parameters, which effectively reduces the configuration error rate and improves system performance. The above method is applicable to various wireless networks and is suitable for self-configuration of LTE (Long Term Evolution) base station SON (Self Organizing Networks).

It is apparent that those skilled in the art can make various modifications and variations to the invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and modifications of the invention
