The wireless transceiver 200 communicates with the second mobile terminal 110 or transmits and receives information through the server 400 or the sensor 100 connected to the mobile convergence network 300. . In addition, it performs a function of transmitting and receiving radio signals with a mobile communication network including a base station and an exchange station so as to perform a basic mobile terminal communication function.

The voice processing unit 210 outputs the information converted into a voice out of a helper service generated by using the information received through the wireless transceiver 200 under the control of the central controller 220 to the outside through the speaker, or moves to the first movement. The voice input by the user of the terminal 100 through the microphone is transmitted to the second mobile terminal 110.

The key input unit 250 performs a function of inputting a series of information for receiving a service desired by the user through the mobile terminal 200 or provides a user interface of the mobile terminal 200. The input signal is transmitted to the central controller 220 using the keypad included in the terminal.

3 is a structural diagram of a smart helper service unit of a mobile terminal with context awareness according to an embodiment of the present invention.

In order to provide a smart helper service, the mobile terminal 200 is attached to a location sensor 110 for providing the current location information of the user, an environmental sensor 120 for providing information on the surrounding situation of the dynamically changing user, and attached to the user. Collects information sensed from the biosensor 130 for recognizing the biological and health conditions such as body temperature, blood pressure, pulse, blood sugar, and the five sense sensors 140 for recognizing user's sensory information, and various wireless communication access networks coexist. In the overlapping radio cell environment, the mobile terminal communicates with other mobile terminals or interworks with service servers through the mobile convergence network 300. It also receives service requirements from the user and communicates with various input / output devices around the user.

Referring to FIG. 3, the configuration of the mobile terminal 200 is described in detail. The mobile terminal 200 includes a sensor matching unit 277, a multi-mode wireless transmission unit 278, an input / output matching unit 279, and a context management unit ( 273, a profile manager 274, a communication protocol manager 275, an input / output information manager 276, and a service manager 272. The context manager 273, the profile manager 274, the communication protocol manager 275, and the input / output information manager 276 are referred to as an information manager.

In conjunction with the sensor matching unit 277 which acquires information sensed from the sensor unit 100 including various sensors, the context manager 273 continuously collects the sensing information by the context engine and refines it through the context abstraction. A generated context Context refers to dynamic information of a user in order to provide a customized service to the user in a situational awareness.

The context manager 273 includes a context collecting module for collecting sensed information, a context abstraction module for creating a context by abstracting the collected information, and a context control module for controlling the context manager 273 to enable such a function. . At this time, the reason for creating a refined context is different from an input method by a direct request from an existing user.In the application layer, information is collected from a plurality of distributed communication devices or sensors for an intelligent personalization service based on situational awareness. This is because a process of refining into more meaningful information through contextual abstraction of ready-to-use form is required.

Context-based context awareness technology collects information to better understand location information and surroundings of users and generates meaningful abstracted information from a large amount of information periodically collected. In addition, by separating the context manager 273 and various application layers independently from each other for physical sensors that are dynamically added and removed, it is difficult to minimize and predict the ripple effect of adding or deleting sensors or application devices. It is possible to improve scalability and adaptability in the development of next generation mobile communication service.

The multimode wireless transmitter 278 supports the selective use of an optimal wireless network in an overlapping radio and environment in which various wireless networks coexist. The multi-mode wireless transmitter 278 performs communication protocol control and media control by the profile manager 274 that manages service / user / device profile and privacy information by the profile engine or the communication protocol engine, and performs communication protocol matching. The data of the communication protocol manager 275 which combines in a suitable message form is transmitted to the server unit 400 through the mobile convergence network 300.

The profile manager 274 is a profile collection module of a service / user / device for collecting service / user / device profile information received from the multi-mode wireless transmitter 278 and privacy information for managing privacy information of a service / user / device. It includes a profile control module for controlling the management module and the profile manager 274 to perform the function. Here, the service / user / device denotes a user performing wireless communication, a service provided by the user, and a device of the user.

The communication protocol manager 275 is a communication protocol matching module for matching various communication protocols using information received from the multi-mode wireless transmitter 278, a communication protocol control module for controlling information transmission and reception according to the communication protocol, and voice or video. It includes a media control module for controlling various types of media such as and the like and a protocol control module for controlling to perform the function.

The input / output information management unit 276 includes a user matching module, a content conversion module, a multilingual conversion module, and an input / output matching control module. The input / output information management unit 276 analyzes input information received from the user by the input / output matching control module to the request information transmitted from the user or the local input / output device through the input / output matching unit 279 to determine the user's requirements. In addition, based on the service profile and the context and the capabilities of the mobile terminal, the conversion is performed in the content or language suitable for the user.

The service manager 272 includes a service discovery module, a service selection module, a service configuration module, and a service adaptation module.

The service discovery module discovers a service that can be used autonomously according to the situation by using the user's context information, the user's profile and preferences, and selects an optimal service from the service selection module. The service configuration module negotiates a quality of service and configures the service terminal to be suitable for a user terminal or a service. In addition, the service adaptation module processes the information about the selected service in accordance with a situation in which the mobile terminal has changed into a form that can be processed by the mobile terminal.

The collection of information for the provision of services may utilize sensors or user-machine interfaces. Information input by a user's direct request through a user-machine interface such as a keypad of the mobile terminal 200 has a high priority in determining a situational service and can be directly applied to an application. On the other hand, the surrounding situation information collected from a plurality of computers or sensor units 100 is generally preferably shared by a plurality of users or applications located in a close area, and is not directly usable at the application layer. There is a need for an abstraction process that collects information from and constructs more refined information.

When managing such situation information, if the user's situation information introduced through various paths is separated from each terminal and managed in an infrastructure-based centralized manner, the independence of the situation information is maintained, and the stored situation information can be shared among various applications or services. If such management is not possible, it should be handled in a device-oriented distributed manner. In the embodiment of the present invention, since the mobile terminal should be easy to be quickly applied in various mobile environments, a device-based sensing information collection method is applied, and information collected from a small number of sensors in consideration of the limited processing capability of the mobile terminal. It is necessary to support a context management technique that can easily make accurate judgments about various situations.

In addition, the information collected from the local service server 430 is input through the multi-mode wireless transmitter 278 and generated by the profile manager 274 as service / user / device profile and privacy information (S130).

At this time, if the user wants to receive video and voice services in Korean voice and video for not only the location information of the place where the user is currently located in his mobile terminal 200, but also the shop information of the surroundings, the request information related to the mobile terminal ( 200). Information at this time is input to the input / output information management unit 276 through the input / output matching unit 279.

The mobile terminal 200 obtains service information that can be provided to the user among various service information related to a place where the user is located in the local service server 430 through the service manager 272 based on the user request information related thereto (S150). In operation S160, service information for providing service information to the user is processed based on the request information S140 received from the user.
