A control system and a control policy of voice UPnP devices through PSTN}

The present invention relates to a UPnP capable device control system and a control method, and more particularly, to a UPnP capable device control system and a UPnP capable device control method capable of controlling a UPnP capable device by voice through a general telephone network and a mobile telephone.

Recently, JINI, Home Wide Web (HWW), Home Audio Video Interoperability (HAVi), UPnP, etc. have been proposed as software middleware and are developing competitively. Among them, UPnP is a standard that makes it easy to use services provided by various devices participating in the network. For example, when a printer is connected to a network, it can be used immediately without any additional process such as installing a driver.

UPnP-enabled devices support the protocol defined by UPnP and provide the definition and presentation functions for the services supported by the device. Services provided by UPnP-capable devices can be accessed through a control point or an Ethernet browser in the network. The control point uses UPnP's Simple Service Discovery Protocol (SSDP) to find available services connected to the network, and obtains and controls a service definition described in XML language from the services. The presentation capabilities provided by UPnP-capable devices in the form of HTML (Hyper Text Markup Language) documents serve as a user interface when using the service at the control point.

The application field of UPnP capable devices is expected to be largely for office or home use. In general, the application technology of UPnP capable devices is in the spotlight due to the lack of expertise in computers and communication networks.

5 and 6 are flowcharts for explaining a UPnP capable device control method using wired and mobile telephones according to the present invention.

UPnP capable device control method using a wired and mobile phone according to the present invention in the case of controlling the UPnP capable device (10, 11, 12) by transmitting a command from the wired and mobile phones (14, 15) to the voice gateway (13) On the contrary, the voice gateway 13 notifies its own state change from the UPnP-capable device 10, 11 and 12, and calls the wired and mobile phones 14 and 15 from the voice gateway 13 to notify the state change. There is a case.

First, when a control command is transmitted from the wired and mobile telephones 14 and 15 to the UPnP-capable device, first, as shown in FIG. 5, the wired and mobile telephones 14 and 15 of FIG. When receiving a control command as shown in (c), (e) and (g) (S500), the control command is general in the PSTN interface unit 23 as shown in (a), (c) and (g) of FIG. In the case of a call processing signal or a DTMF signal, it is transmitted to the VXML interpreter 31 through the DTMF processing unit 33, and in the case of voice as in the case of FIG. 4E, the VXML interpreter 31 is passed through the ASR processing unit 32. Is delivered). The VXML interpreter 31 interprets the control command (S501), and when the control command relates to the control of the UPnP capable device as shown in FIG. 4 (h) (S502), the UPnP capable device command is transmitted to the document converter 30. This is delivered to the UPnP-capable devices 10, 11, and 12 via the UPnP protocol processing unit 21 to control home appliances (S505). If the control command is a general control command as shown in (b), (d), and (f) of FIG. 4 (S502), the character string generated by the VXML interpreter 31 is transferred to the TTS processing unit 34 and converted into voice to be converted into a PSTN. The wired and mobile phones 14 and 15 are transferred and processed through the interface unit 23 (S503). At the end of the processing as shown in Fig. 4H, it is checked whether or not the service is to be continued (S505).

First, in the case of informing the state change from the UPnP-capable devices 10, 11, 12 to the wired and mobile telephones 14, 15, first, as shown in FIG. 6, the UPnP-capable devices 10, 11, 12 are previously informed. After a state change is detected, for example, when a front door is opened or a gas leak is detected, the voice gateway 13 is notified (S600), and the UPnP protocol processor 21 This is transmitted to the VXML interpreter 31 via the document change unit 30. The VXML interpreter 31 connects to the wired and mobile telephones 14 and 15 through the TTS processing unit 34 and the PSTN interface 23 (S601), and generates a character string informing of the state change, and generates the TTS processing unit 34. The voice signal is converted into voice through the PSTN interface 23 and transmitted to the wired and mobile phones 14 and 15 through the PSTN interface 23 (S602).
