In the case of accessing the service via the heterogeneous network, not only the time, location and service category of using the service were considered but the service was not classified according to the specific criteria because the user experience quality information was not used.

In the embodiment of the present invention, various services are classified into service groups according to a service classification standard in a heterogeneous network environment, and a service group is connected to a wireless network through one RAT of various RAT according to a RAT selection criterion. On the other hand, even if the same service is provided, it can be connected to the wireless network through different RATs through different service groups.

Here, the service classification reference includes at least one of time, place, service category, and user experience quality information, and the RAT selection criterion may include at least one of time, place, service category, and user experience quality information. This RAT selection criterion can be set independently of the service classification criterion or set the same.

In this case, the location of the terminal can be used as a criterion for selecting the service RAT. That is, the service RAT for the cellular network is selected or the service RAT for the Wi-Fi is selected according to the location of the terminal. This example indicates that the terminal can use the service classification standard and the RAT selection criterion simultaneously or separately when providing the service that can be provided by connecting to the heterogeneous network.

The measured user experience quality information can be used as a service classification reference and a RAT selection reference.

In addition, such user-perceived quality information is transmitted periodically or non-periodically via a feedback channel according to a request of the network or a user, and is utilized for managing the load of the heterogeneous network, providing the managed service, and operating the base station resource for improving the user's perception quality .

Various services required by the terminal, that is, various services provided through the content servers 1 to s, are provided to the terminal through a heterogeneous network composed of different RATs. 3, a network refers to a different core network to which a wireless RAT is connected, for example, a public internet, a managed network of a mobile communication provider, a wired network, or a proximity network. And the like.

The terminal can receive the service by accessing the optimum RAT for each service. The terminal recognizes the environment of the user and the surrounding environment, and receives the service by selecting the optimal RAT for each service.

As shown in FIG. 3, in the case of the service 1, the content server 1 accesses the network 1 through the RAT 1 and receives the corresponding service from the content server 1. In the case of the service 2, the content server 2 accesses the network 2 through the RAT 1 or RAT 2, Service is provided. In the case of the service 3, the service is connected to the network 1 through the RAT 1 and the corresponding service is provided from the content server 1, or is accessed through the network m through the RAT 3 to receive the service from the content server s.

In the first embodiment of the present invention, various services that can be provided by the terminal are classified into service groups according to the service classification criteria, and the service groups are connected to the wireless network through various RATs according to the RAT selection criterion.

Specifically, services are classified into service groups according to service classification standards such as time, place, service category, user experience quality information, and the service group classified as such is classified into RAT selection criteria, Etc. are connected to the wireless network through one RAT among various RATs according to the RAT selection criterion independently or in the same manner as the service classification standard.

The service classifier 10 classifies a plurality of services into service groups according to a service classifying criterion. For example, as shown in FIG. 4, services can be classified into service group 1, service group 2, and service group 3. Here, the service 1 and the service 2 are classified into the service group 1, the service 3 and the service 4 are classified into the service group 2, and the service 1 and the service 5 are classified into the service group 3. At this time, the service 1 can be classified into the service group 1 and the service group 5.

The RAT selector 20 connects to the optimal RAT for each service according to the RAT selection criterion. That is, the service group is connected to one of the plurality of RAT transceivers 30 according to the RAT selection criterion. Accordingly, the service of the service group is provided through the optimal RAT transceiver selected in consideration of the user and the surrounding environment.

The RAT transceiver 30 provides a connection via a predetermined RAT.

The terminal can provide a plurality of services by connecting to a heterogeneous network through a single RAT transceiver among a plurality of RAT transceivers.

The user's perceptual quality information may be measured through user's direct input or functional modules of the terminal such as various sensors. The measured information may be stored in the information storage 41 in the form of raw data. Or an output value output from the user interface unit 42 may be processed through a predetermined QoP measurement algorithm and stored in the information storage unit 41. [ The information storage unit 41 may store user experience quality information in the form of row data or may store user experience quality information generated through the QoP measurement algorithm. The information storage unit 41 may be implemented in a database format.

The user interface unit 42 receives various output values related to the response operation of the user. The user interface unit 42 includes various user interface devices included in the terminal. The user interface unit 42 receives user's response operations such as touch, sound, wind, waving, facial expression, and input frequency through the user interface device. Here, the response operation of the user indicates an action indicating the user's response to the service provided through the terminal.

The quality information measuring unit 43 processes the output values output through the user interface unit 42 through a predetermined QoP measurement algorithm to generate user's perception quality information and stores the information in the information storage unit 41. [

The user experience quality information processed in this way and stored in the information storage unit 41 can be used for the service classification reference and the RAT selection criterion.

That is, one of the RAT transceivers for performing connection based on different RATs for connection is selected according to the RAT selection criterion for each service group. In this case, too, the access point 100 obtains the parameters included in the RAT selection criterion, for example, time, place, service category, and user experience quality information, and selects the RAT transceiver corresponding to the service group based on the information S120, S130).
