The present invention relates to a method and system for providing base station information in a mobile communication system, and in particular, provides location information and base station type of a base station to a network management system (NMS) / operation support system (OOS) in a code division multiple access system. A method and system for

A network management system (NMS) / operation support system (OOS) of a network management layer (NOS) for providing base station information of a mobile communication system is defined in TS 23.002 proposed by 3GPP. The NMS / OOS requests a specific network (Functional or Physical resource) of the mobile communication network to the network management agent (Agent) of the element management layer (Element Management Layer) through a standard-based interface (Standard-based Interface) . At this time, the content requested by the NMS / OOS is transmitted through a standard interface, and the requested information varies, and among them, configuration information of a communication network system is required. Here, the configuration information of the communication network system provided by the network management agent includes 'BscFunction', 'BtsFunction', 'Abis', 'Cell', and the like. An operation for providing such configuration information will be described with reference to the drawings.

1 is a block diagram illustrating a base station information provided by a network management agent in a general mobile communication system. In this case, a manager is a manager for managing a network in NMS / OOS of a network management layer.

The manager 10 transmits a request message (get request) to the communication management agent (Agent) 20 to receive the base station information, that is, the configuration information. Then, the communication management agent 20 includes configuration information (BtsFuntionID, User Label, BtsFunction-Abis) in the response message (get Respose) to the manager 10.

Among the configuration information, BtsFuntion is defined in 3Gpp2 S.SOO28. That is, the original text is defined as "This Managed Object Class represents BTS functionality. For more information about the BTS, see [50] (3GPP2 S.R005). It inherits for Manager Function."

The BtsFuntion transmits, to the NMS / OOS, through a standard interface, whether or not an alarm occurring in the base station occurs and disappears, and whether the attribute of the base station changes.

Referring to <Table 1> and <Table 2>, various events and data generated from the base station are delivered to NMS / OOS through the standard interface through the characteristics and notification information provided by BtsFuntion proposed by the existing 2GPPS. It can be seen.

However, the characteristics defined in 3GPP2 are not defined other than 'BtsFuntionID', 'userLabel', and 'BtsFuntion-Abis' as shown in Table 1 below, and thus have a weak point to transmit various information. However, NMS / OOS needs the geographical location information of the station and the base station type. This is because the cell management layer establishes a cell plan based on the area information that a cell area can provide. Since the cell service is managed by the base station, the location of the base station is important information for performing the cell plan. do. In addition, since the number of cells is determined according to the base station type, the base station type is also important information for cell planning.

In this way, it is necessary to know the range of a cell accurately so that policy can be efficiently established when planning a cell. If the cell range is too wide because the cell area cannot be accurately measured, it is impossible to provide a mobile communication service. On the contrary, when the gap between cells is narrow, economic waste occurs when operating the mobile communication network. In addition, when the NMS / OOS requests the geographic location of the BTS or the base station type, it is difficult to provide information only by characteristics and notifications.

Accordingly, an object of the present invention is to provide a method and system for providing location information of a base station and a base station type to an NMS / OOS through a standard interface in a mobile communication system.

The method for achieving the object of the present invention, in a mobile communication system including a base station communicating with the mobile terminal, the network management agent for managing the information of the base station to provide the base station information to the manager managing the network A method for determining a base station information request from a manager who manages the network, and if the base station information request is received, searching for the base station and setting the location information and the base station type of the base station; And transmitting the location information and the base station type to the manager managing the network.

The system for achieving the object of the present invention is a system for providing information of the base station in a mobile communication system including a base station communicating with a mobile terminal, requesting the base station information, the request according to the request A manager for managing a network for receiving base station information and estimating the number of cells, and a communication management agent for transmitting location information and base station type of the base station to a manager managing the network when the base station information request is received. It features.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, in an embodiment of the present invention, an element management layer is described as a communication management agent that provides base station location information and base station type.

In the configuration information management layer, BtsFunction, which is one of the configuration information of the communication network system, provides a standardized representation of the exact location of the base station and is displayed using latitude, longitude, and altitude.

The display method is the intersection and the altitude of latitude and longitude, and the content of latitude and longitude is 'hemisphere', 'degree', 'minute' and 'milisecond'. In this case, the altitude is represented by 'm'. The content as shown in FIG. 2 is added to the BtsFunction to deliver the location information of the base station in the NMS / OSS when requested. In addition, BtsType provides information of a base station type that can be recognized by NMS / OOS and predict the number of cells as a string. A BtsFunction providing such information is defined as a BtsType and the added content is as shown in FIGS. 2 and 3.                     

Content added to SECBtsFunction as shown in FIG. 2 and FIG. 3 sequentially indicates parameters of latitude, longitude, altitude, and BtsType of the base station. The characteristics of the SECBtsFunction and the contents of the notification are shown in Table 3 below.
