The embodiment of the present application provides a method for configuring a base station, which is applicable to a base station configuration system, where the base station configuration system includes a base station to be configured and a network management server.

The base station, that is, the public mobile communication base station, is a form of a radio station, and refers to a radio transceiver station that transmits information between the mobile communication switching center and the mobile telephone terminal in a certain radio coverage area, including Acer. Station and micro base station. The basic parameters of the base station need to be configured before the base station is opened for use.

The network management server refers to OAM - Operation Administration and Maintenance. According to the actual needs of the network operation of the operator, the management of the network is generally divided into three categories: Operation, Administration, and Maintenance, or OAM. The operation mainly completes the analysis, prediction, planning and configuration of daily network and business; the maintenance is mainly the daily operation activities of testing and fault management of the network and its services.

Based on the foregoing system architecture, the method provided by the embodiment of the present application is applied to a parameter configuration process of a base station opening or changing parameters, as shown in FIG. 1 , the method includes:

101. The base station to be configured establishes a connection with the network management server, and scans the neighboring base station according to the specified frequency information to obtain the neighbor base station information.

The base station to be configured establishes a connection with the network management server by using an Internet Protocol Address (IP) of the locally stored network management server.

The specified frequency information includes a combination of one or more of a frequency supported by the base station, a frequency configured by default, and frequency information corresponding to an Internet Protocol address of the network management server.

The neighboring cell site information includes a location, a frequency, a transmission power, a physical cell identity (PCI) of the neighboring cell, and an evolved-universal mobile communication system, a terrestrial radio access network, a global identifier (ECGI, E-UTRAN Cell Global Identifier, Evolved UMTS Terrestrial Radio Access Network Cell Global Identifier), Cell ID (Cell Identity), Tracking Area Code (TAC), Internet Protocol Address, and the like. The Internet Protocol address includes IP of the core network (MME IP, Mobility Management Entity IP), IP of the enhanced gateway (eGW IP, enhanced GateWay IP), and IP of the service gateway (sGW IP, serving GateWay IP).

For the base station to be configured to scan the neighboring base station to obtain the neighboring base station information according to the specified frequency information, for example, if the frequency to be configured by the base station is 2.3 GHz, the scanning neighboring area of the base station to be configured at the 2.3 GHz frequency is configured. Base station. For example, if the base station to be configured is a mobile base station, the default configuration frequency is 1.9 GHz, 2.3 GHz, and 2.6 GHz. The base station to be configured scans the neighbor base stations at these frequency points.

102. The base station to be configured sends neighbor base station information to the network management server.

103. The network management server determines, according to neighbor base station information, an optional configuration parameter of the to-be-configured base station.

The network management server determines the optional configuration parameters of the to-be-configured base station in different manners according to the type of the neighboring base station, which will be described in detail in subsequent steps 1031 to 1034.

The base station optional configuration parameters include a base station selectable physical layer cell identifier set (PCI set), an evolved-universal mobile communication system terrestrial radio access network cell global identifier set (ECGI set), and a cell identifier set ( Cell ID set), tracking area code set (TAC set), Internet protocol address (IP address) set.

104. The network management server sends the optional configuration parameter to the to-be-configured base station.

105. The to-be-configured base station determines a configuration parameter according to the optional configuration parameter.

The base station to be configured to be configured determines the final configuration parameter from the optional configuration parameters. For example, when the base station to be configured is a micro base station, a PCI that does not conflict and be confused with the neighboring micro base station may be selected from the optional configuration parameters, and the same TAC and eGW IP as the neighboring micro base station are selected. And sGW IP.

The embodiment of the present application provides a method for configuring a base station, by using a base station to interact with a network management server, determining configuration parameters of the base station, completing configuration, reducing a large workload of manually performing base station configuration, saving manpower, material resources, and financial resources, and reducing labor. Interventions avoid human error and make it easier to deploy a large number of base stations in a wide area.

Further, in combination with the foregoing method, when the network type of the neighboring cell is different, the method for the network management server to determine the optional configuration parameter is different, and another possible implementation manner of the embodiment of the present application provides the following for the implementation of step 103. Different method flows, including:

Before determining, by the network management server, the optional configuration parameter according to the neighbor base station information, first determining a base station type of the neighboring base station. For example, if the neighboring base station is a macro base station or a micro base station, there are multiple methods: it can be determined according to the PCI or TAC of the neighboring base station, when the PCI or TAC of the neighboring base station belongs to the PCI set or the TAC set of the macro base station in the network planning. The macro base station is a micro base station when the PCI or TAC of the neighboring base station belongs to the PCI set or the TAC set of the micro base station in the network planning. The base station may be a macro base station when the transmit power of the neighboring base station is greater than a specified power, for example, 1 W, and is a micro base station when the transmit power of the neighbor base station is less than a specified power. It can also be based on the frequency point information of the neighboring base station. For example, in China Mobile, the frequency of the neighboring base station is 2.3 GHz. The base station of the frequency point can only be deployed indoors as a micro base station; other frequency points, such as 1.9 GHz. 2.6GHz is a macro base station. According to the ECGI information of the neighboring base station, when the base station ID in the ECGI is a macro base station in the network, the macro base station is the micro base station, and vice versa.

It should be noted that the type of the base station includes not only the macro base station and the micro base station, but also the pico base station and the distributed base station, etc., which are not discussed here.

The first method, as shown in Fig. 2(a), can be performed in accordance with the following step 1031.

1031. When there is only one type of base station in the neighboring cell, the optional configuration parameter is determined according to information of the type of base station.

For the implementation of step 1031, the base station is a macro base station, and the base station to be configured is a micro base station.

The network management server determines the optional configuration parameter according to an optional configuration parameter of the micro base station to be configured corresponding to the macro base station in the network planning. For example, the PCI set, the TAC set, the eGW IP, the MME IP, and the sGW IP of the to-be-configured micro base station are determined according to the location of the neighboring macro base station.

Similarly, when the base station to be configured is a macro base station, the network management server may also infer the optional configuration parameters of the to-be-configured micro base station by using the neighboring macro base station information according to the planning in the network.

For the implementation of step 1031, the base station is a micro base station, and the base station to be configured is also illustrated by the micro base station.

The optional configuration parameters of the micro base station to be configured are determined according to the neighboring cell micro base station information in the network planning. For example, the PCI set, the TAC set, the eGW IP, the MME IP, and the sGW IP of the micro base station to be configured are determined according to the PCI, the TAC, the eGW IP, the MME IP, and the sGW IP of the neighboring micro base station. To avoid PCI conflict and confusion, the optional PCI set of the micro base station to be configured needs to remove the PCI of the neighboring micro base station, and the TAC, eGW IP, MME IP, and sGW IP of the to-be-configured micro base station can be used with the neighboring micro base station. Make the same configuration.

Similarly, when the base station to be configured is a macro base station, the network management server may also summarize the optional configuration parameters of the to-be-configured macro base station by using the neighboring micro base station information according to the planning in the network.

In the second method, as shown in FIG. 2(b), step 3 can be performed in the following step 1032.

1032. When there are several types of base stations in the neighboring cell, configure the optional configuration parameters according to the information of the plurality of types of base stations.

For the implementation of the step 1032, a plurality of types of base stations are used as the macro base station and the micro base station, and the base station to be configured is an example of the micro base station.

When the neighboring cell has a macro base station and a micro base station, the optional configuration parameters of the to-be-configured base station are determined by combining two examples in step 1031.

It should be noted that, in step 1031 and step 1032, of course, the neighboring area may also have a pico base station, a distributed base station, etc., which are not discussed here.

In the third method, as shown in FIG. 2(c), step 3 can be performed in the following step 1033.

1033. When there is no base station in the neighboring cell, determine the optional configuration parameter according to the information of the to-be-configured base station itself.

It should be noted that the neighboring area may not have a base station, and the network management server determines the optional configuration parameter according to the information of the base station to be configured. The information of the base station to be configured includes parameters such as a home location, a frequency point, a transmission power, a geographical location information, and a product serial number of the base station to be configured.

When there is no base station in the neighboring cell, the base station to be configured will report some special identifiers, such as 0xFF, indicating that the neighboring base station is not scanned temporarily. When the network management server receives the special identifier sent by the base station to be configured, the optional configuration parameter is determined according to default parameters such as the home location of the base station to be configured.

It should be noted that, in step 1031 and step 1032, when there is a base station in the neighboring cell, the network management server may further determine the optional configuration of the to-be-configured base station by combining the information of the neighboring cell base station and the information of the base station to be configured. parameter.

Further, in combination with the foregoing method, before the connection between the to-be-configured base station and the network management server, another possible implementation manner of the embodiment of the present application further provides the following method flow, which is performed before step 101, as shown in FIG. ,include:

106. The to-be-configured base station interacts with the security gateway to establish a secure tunnel.

Among them, the security gateway is a fusion of various technologies, with an important and unique protection, ranging from protocol level to very complex application level filtering. The purpose of the setup is to prevent Internet or extranet insecurity from spreading to the intranet of your own business or organization.

The base station to be configured interacts with the security gateway through a locally saved security gateway IP, establishes a security tunnel, and establishes a connection with the network management server. For example, the base station to be configured to save the security gateway IP is 192.168.AAA.BBB, then the base station first establishes a secure tunnel with the security gateway, completes the secure connection, and implements interworking between the base station to be configured and the network management server and the MME.

It is to be noted that, if the to-be-configured base station interacts with the security gateway and establishes a security tunnel, the base station to be configured in step 101 scans the neighboring base station to obtain neighboring cell site information according to the specified frequency information, and the to-be-configured base station may further The frequency information corresponding to the IP address of the security gateway scans the neighboring base station. For example, the IP address of the security gateway is 192.168.AAA.BBB. According to the IP address, the IP address of the security gateway IP can be obtained from China Mobile Beijing, according to the mobile network of Beijing. In the case of frequency, such as 1.9 GHz and 2.6 GHz, the base station to be configured scans the neighboring base stations at these frequencies.

Further, in combination with the foregoing method flow, in order to prevent the base station to be configured from being missed when scanning the neighboring base station, another method of the embodiment of the present application is before the base station to be configured determines the configuration parameter according to the optional configuration parameter. The possible implementation manner also provides the following method flow, which is performed before step 105, as shown in FIG. 4, and includes:

107. The to-be-configured base station scans the neighboring base station again to obtain neighbor base station information according to the specified frequency information.

And the determining, by the base station to be configured, the configuration parameter according to the optional configuration parameter of the base station, including:

1051. The to-be-configured base station determines a configuration parameter according to the neighboring cell base station information and the base station optional configuration parameter.

The base station to be configured comprehensively scans the neighbor base station information that is obtained by re-scanning, and determines the final configuration parameter from the optional configuration parameter.

Further, after the configuration of the configuration parameter by the to-be-configured base station according to the optional configuration parameter, in order to enable the network management server to acquire the configuration parameters determined by the base station to be configured in time, and store and use it in other base station configurations, the present application is implemented. Another possible implementation of the example further provides the following method flow. After the step 105, as shown in FIG. 5, the method includes:

108. The to-be-configured base station sends the determined configuration parameter to the network management server.

The descriptions of the base station and the network management server are the same as those in the foregoing, and are not described here.
