The present invention relates to an apparatus for diagnosing a base station and a network section in a mobile communication system, and more particularly, to a BTS (BTS Test Terminal Equipment Daughter) inside a base station test unit (BTU) of a mobile communication base station. Throughput and statistical data of PS (Packet Switching) outgoing signals by service type are measured and the measured values are suitable for analyzing and diagnosing the status of specific base station and network sections. A diagnostic apparatus and a method thereof are provided.

In general, a mobile communication system is a communication system that targets mobile devices such as people, cars, ships, trains, and airplanes, which includes key phone systems, mobile phones (mobile phones, vehicle phones), port phones, aircraft phones, and mobile phones. Trains, cruise ships, express buses), radio calling, radiotelephony, satellite mobile communication, amateur radio, and fishing service ships.

The mobile communication system includes an AMPS (Advanced Mobile Phone Service) system using an analog method, a Code Division Multiple Access (CDMA) system using a digital method, a Wideband Code Division Multiple Access (WCDMA), and a TDMA (Time). Division Multiple Access, Time Division Multiple Access (FDMA) system, Frequency Division Multiple Access (FDMA) system, Wireless Local Loop (WLL), CDMA2000-1x, IMT-2000 (International Mobile Telecommunication in the year 2000 , Global mobile communication (GSM) systems, and GSM (Global System for Mobile communication) systems.

The third generation asynchronous system (Universal Mobile Telecommunications System) is a third generation mobile communication system evolved from the European standard GSM, based on the GSM core, by applying WCDMA technology to the Radio Access Network (RAN) Providing a service.

1 is a block diagram of an apparatus for diagnosing a base station and a network section in a conventional mobile communication system.

Where reference number 1 is a terminal (Terminal Equipment, TE), 2 is a mobile station (MS), 3 is Node-B, 4 is a Radio Network Controller (RNC), 5 is SGSN (Serving GPRS Support Node), 6 is a Gateway GPRS Support Node (GGSN), 7 is a GI router, and 8 is a File Transfer Protocol (FTP) server.

Therefore, the asynchronous mobile communication system is largely composed of a terminal device (1) (2), a radio access network, a core network, the radio access network is composed of a base station (Node B) (3) and a base station controller (RNC) (4).

Wireless access networks are connected to three core networks. Therefore, the circuit switched is connected to the CS (Circuit Switched) domain (Domain), the packet switched to the PS (Packet Switched), the broadcast service is connected to the BC (Broadcasting) domain.

In a radio access network, the RNC controls components in the RNC 4 to dynamically allocate radio resources of a UTRAN (UMTS Radio Access Network). And it performs the switching function to deliver the data transmitted through the UTRAN to the appropriate node. Since the RNC 4 is directly connected to the core network, the RNC 4 serves as an access point of a service to all services provided through the core network.

Node B (3) in the radio access network plays the role of the physical layer on the Uu interface, and is responsible for the transmission and reception of data over the air interface. The Node B 3 sets wireless physical channels necessary for data exchange with the terminal according to the control information transmitted from the RNC 4, and converts data transmitted from the upper protocol to the terminal in accordance with a wireless environment. The data received from the terminal is transmitted to the upper layer protocol of the RNC.

The terminal 1 includes a UMTS Subscriber Identity Module (USIM) therein. Since the USIM card can be separated from the UE, a standard interface called Cu is defined between the two.

The USIM is a part storing user's unique information and may be separated from the terminal. The USIM may be somewhat ambiguous, but in practice it takes the form of a physical integrated card (IC) card. The IC card can include various applications or multiple USIM functions.

The core network includes all network components related to subscriber call control, session management, mobility management, and switching within the network.

The core network components can be divided into nodes belonging to a circuit switched (CS) area, a packet switched (PS) area, and a register area.

The circuit switched (CS) area consists of a Mobile Switching Center / Visitor Location Register (MSC / VLR) and a Gateway Mobile Switching Center (GMSC), which can be physically located in the same equipment. The MSC / VLR manages circuit-switched connections, and manages data security as well as mobility management such as location update, location registration, and paging. The GMSC acts as a path through which the circuit switched area is connected to the external network.

The packet switched (PS) area is provided through SGSN 5 and GGSN 6. SGSN 5 manages and supports packet switched services destined for UTRAN. And it includes a function such as routing area update (Routing Area Update), location information registration, call for the mobility management of the terminal receiving the packet exchange service. The GGSN 6 serves as a path connecting the packet switched area to another packet switched network such as the Internet network.

The Iu interface is used as the name of the radio access network (3) (4) and the core network (5) (6), and Iub / Iur is the interface name between systems in the UTRAN. The air interface, named Uu, is an interface that incorporates WCDMA technology.

The GI router 7 is also a network layer device that uses one or more matrices to determine the optimal path to which network traffic should be forwarded. The GI router 7 forwards the packet between the GGSN 6 and the FTP server 8 based on the network layer information.

FTP is an application protocol and is part of the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol stack used to transfer files between network nodes. FTP is defined in RFC 959. Thus, the FTP server 8 is connected to the mobile terminal 2 via the GI router 7 to perform file transfer.
