The present invention relates to a method and apparatus for measuring wireless quality information based on OMA (Open Mobile Alliance) device management (DM), and more specifically, using a DiagMon (Diagnostics and Monitoring) function among OMA DM functions of a mobile communication terminal. The present invention relates to a technology for measuring wireless quality information in a mobile communication terminal.

In early 2000, OMA developed new media services using existing networks to increase profitability in Europe and the Americas.Operating market leaders and system suppliers such as Nokia have the same interests to quickly establish and access service standards according to market needs. It is an international standardization organization created in terms of securing interoperability between various terminals and systems independent of the network.

The OMA defines the approximate objectives and areas of activity as follows: OMA's purpose is to expand the market for the entire mobile industry by removing geographic, operator and device barriers for interoperability and allowing users to experience continuous and easy mobile services. In other words, the purpose of OMA is to activate the mobile telecommunications market, enhance the interoperability of mobile telecommunications service applications, and establish mobile telecommunications service application standards (cooperating with standards organizations) independently of various networks, terrains and operators. OMA's activities include DS (Data Synchronization), DM (Device Management), DRM (Digital Rights Management), LBS (Location Based Service), and Game Service. Each activity is organized by WG (Working Group). .

The quality of wireless sections in mobile networks continues to change with changes in topography or traffic density due to climate change, large-scale civil works, and new buildings in urban areas. In addition, a number of repeaters installed in the city is easy to cause a malfunction, such malfunction of the repeater is one of the factors that deteriorate the quality of the wireless section of the mobile communication network.

As a result, mobile operators have invested a lot of operators to monitor the quality of the wireless section of the jurisdiction periodically. The goal of the quality measurement of the wireless section is a hot spot area in which the traffic density is higher than the surrounding area due to the construction of a shopping mall and the like, along with a role of detecting a failure such as a repeater; Coverage hole where signals are hard to reach from base stations such as apartment complex, building basement floor, subway, tunnel, mountain area; Cell redesign and base station capacity increase by detecting pilot pollution area where signals from many base stations reach a similar intensity due to the long distance of radio waves through relatively open spaces such as upper floors and river banks This is to take appropriate measures at the time of installation, small base station and repeater installation.

In the conventional method of measuring the quality of a wireless section, an operator has a wireless section quality measuring device composed of a mobile communication terminal, a data logging device, a GPS receiver, etc. in a vehicle, and then moves around a designated area. In addition, the measurement data collected from the data logging equipment was brought to the operation center for analysis.

However, this radio quality measurement method was inefficient in terms of cost and time because many operation personnel had to be continuously administered and it took a long time to collect, analyze, and take appropriate measures.

On the other hand, in the conventional wireless quality measurement method, a more advanced form is equipped with a wireless section quality measurement equipment in a mobile vehicle including a public transport such as taxi, bus, etc., if necessary, the operator commands via SMS from the operation center Lower the radio quality measurement equipment to measure the quality of the radio section and transmit it to the central server through SMS, the central server collects the measurement data transmitted from each telemetry device in real time, and then analyze and utilize That's the way.

However, even in this method, the wireless section quality measuring equipment is expensive equipment unlike the general user terminal, so that it is difficult to mass-distribute.When it is mounted on a taxi or a bus, the measurement is made mainly on the main highway and these vehicles are desired by the operators. It is unlikely to exist in the desired location in time, so it lacks reality. As a result, mobile operators have to carry equipment in dedicated measurement vehicles and administer them when necessary, which is inefficient in terms of cost and time as in the conventional method.
