The multi-radio interface classes defined in the above-described manner are shown in Tables 24 to 26 below. Tables 24 to 26 illustrate in detail all the operations associated with the three interface classes described above.

According to the above-described embodiment, the multi-radio interface providing three basic services can support activation / deactivation of RAs. That is, the reconfigurable mobile device may support simultaneous execution of multiple radio access technologies (RATs) and may have a combination of radio applications that is optimal according to the communication environment of the terminal at present.

In this case, the mobility policy manager (MPM) of the communication service layer receives the current radio application list (RAs List) information from the configuration manager (CM) of the radio control framework, and activates or deactivates one or more radio applications / deactivation) to the radio control framework's radio connection manager (RCM). The radio connection manager (RCM) can execute the commands and return the results to the mobility policy manager (MPM).

In addition, the multi-radio interface can support flexible data flow. That is, the reconfigurable mobile device detects the occurrence of a situation in which a data flow that is currently used needs to be moved, separated, or combined depending on the terminal communication environment (for example, Handover).

In this case, the mobility policy manager (MPM) of the communication service layer sends a change data flow request, a separate data flow request, or a request moving / separating / combining data flows to the radio connection manager (RCM) Lt; / RTI > In response to this message, the radio connection manager can perform the service and send an approval or failure message to the mobility policy manager.

In addition, the multi-radio interface can support error reporting. That is, if reconfigurable mobile devices run multiple wireless access technologies (RATs) simultaneously, unexpected errors may occur. In this situation, the connection manager (CM) of the radio control framework may report an error to the mobility policy manager (MPM) of the communication service layer.

For example, when a spectral resource collision occurs, the multi-radio controller (MRC) recognizes and notifies the connection manager, and the connection manager can report the error to the mobility policy manager.

Thus, the reconfigurable mobile device according to the present embodiment detects an error exceeding the capabilities of the terminal or reconfigurable mobile device and / or a resource conflict related error of radio applications operating on the mobile device and reports the detected error to the communication service layer It is possible to prevent a problem such as an incomplete operation of the mobile device or an undesired operation stop.

Hereinafter, procedures in which a mobile device having a communication service layer, a radio control framework, and a multi-radio interface according to the present invention actually operate in an environment requiring a multi-mode environment, a handover environment, and an error report will be described.

The control unit of the mobile device referred to in the following description may be a combination of components or components using a service supported by the multi-radio interface, and may be a component of a real-time operating system and / or a radio control framework of a radio computer A radio controller, or a radio controller, or a component of a communication service layer.

7 is a flow diagram of a method for controlling an integrated radio application in a reconfigurable mobile device in accordance with an embodiment of the present invention.

Referring to FIG. 7, the reconfigurable mobile device according to the present embodiment detects the wireless environment of the mobile device (S71). In this step, the communication service layer of the reconfigurable mobile device can receive the integrated radio application list from the radio control framework.

Next, it is determined whether the wireless environment is suitable for the multimode (S72). This step may include determining whether the wireless environment has changed from an environment suitable for a single mode to an environment suitable for a multi-mode.

Here, the multi-mode refers to a specific radio access environment in which a plurality of different radio systems (RATs) are mixed, and the single mode refers to a specific radio access environment in which only a single radio system exists.

In the multi-mode, based on the integrated radio application list, two or more radio applications may be activated at the same time, or at least one radio application may be activated in addition to the currently activated radio application (S73). As such, at this stage, one or more radio applications may be activated at the same time.

Next, it is determined whether the wireless environment maintains an environment suitable for the multimode (S74). This step is for judging whether the wireless environment is maintained in the multi-mode or converted into the single mode.

If the environment is suitable for the multi-mode, it is determined that the radio environment has not changed and the control state of the radio applications currently operating in the multi-mode is maintained (S75).

On the other hand, if the environment is not suitable for the multi-mode, the reconfigurable mobile device recognizes the change of the radio environment and deactivates one or more radio applications based on the integrated radio application list (S76). At this stage one or more radio applications can be deactivated at the same time.

That is, the handover may be a horizontal handover or a combination of the two (vertical handover and horizontal handover). Here, the vertical handover refers to a function of maintaining a service when a terminal capable of multiple interfaces is moved between networks to which different technologies are applied, and a handover in which an OSI (Open System Interconnection) . ≪ / RTI > The horizontal handover may refer to a function of maintaining a service when a mobile device moves between mobile communication cells within a network to which the same technology is applied.

Next, the control unit of the reconfigurable mobile device determines handover from the first and second wireless environments to the third wireless environment according to the detection of the third wireless environment different from the first wireless environment and the second wireless environment, A handover from the first wireless environment to the second wireless environment and the third wireless environment can be handled by sensing a second wireless environment different from the first wireless environment and a third wireless environment different from the first and second wireless environments in the wireless environment (S83).

In the case of handover, the control unit of the reconfigurable mobile device may perform a data flow for a first radio application operating in a first radio environment and a second radio application operating in a second radio environment for a multiple-to-one (N: The data flow for a first radio application operating in a first radio environment for a one-to-many (1: M) handover, or a second radio application running in a second radio environment, (S84) the data flow control for changing the data flow for delivery to the second radio application operating in the wireless environment and the third radio application operating in the third wireless environment.

If it is not a multiple-to-one handover or a one-to-many handover, the control unit of the reconfigurable mobile apparatus can perform the general handover control (S85).

On the other hand, the control unit of the reconfigurable mobile device according to the present embodiment also performs a one-to-many or many-to-one handover simultaneously or sequentially to perform a multi-handover (N: M or M: To perform data flow control.

9 is a flowchart of a method for controlling an integrated radio application in a reconfigurable mobile device in accordance with another embodiment of the present invention.

Referring to FIG. 9, the reconfigurable mobile device according to the present embodiment monitors radio applications operating in the mobile device (S91).

Next, it is determined whether a resource related error has occurred (S92). In this step, the control unit operating on the radio computer of the reconfigurable mobile device can detect errors related to the spectral resources of, for example, radio applications.

If an error is detected, the control may forward an error report or error message to the reconfigurable mobile device's communication service layer (S93). On the other hand, if no error is detected, the current error reporting interface can be terminated before the error report.

Meanwhile, in the above-described embodiments, the reconfigurable mobile device is a reconfigurable mobile device having a multi-radio interface for connecting services between a communication service layer and a radio control framework on a radio computer, The following three groups of steps may be included for control of the system.

First, the communication service layer receives an integrated radio application list from the radio control framework and simultaneously activates or deactivates one or more radio applications based on the integrated radio application list.

The second is to detect a plurality of different wireless environments in one wireless environment or to detect a one-to-many handover or a many-to-one handover according to detection of another wireless environment in a plurality of wireless environments, Converting a first radio application operating in a first radio environment into second and third radio applications operating independently in second and third radio environments or a second and third radio applications operating in second and third radio environments, And converting the third radio applications into a first radio application operating in a first wireless environment.
