Description

TECHNICAL FIELD [0001] The present invention relates to an event notification method and apparatus for a home network,

The present invention relates to a home network, and more particularly, to a method and apparatus for providing an event notification in a home network using UPnP (Universal Plug and Play).

In general, a home network is a private network based on an Internet Protocol (IP). Such a home network connects and controls various devices such as a personal computer (PC), an intelligent product, and a wireless device through a single network through middleware, which is a common virtual computing environment. The middleware connects various devices in a peer-to-peer manner to enable communication between devices. Up to now, middleware has been proposed as Home AV Interoperability (HAVI), Universal Plug and Play (UPnP), Java Intelligent Network Infrastructure (Jini), and Home Wide Web (HWW).

Among them, the UPnP network is the most widely used home network technology, and defines a UPnP device, a UPnP service and a protocol therebetween. The UPnP network is composed of a controlled device (CD), which is a home network device connected to and controlled by an IP-based home network, and a control point (CP), which is a device that controls the controlled device.

The control point is a device that performs control on the controlled device, and requests an event from the controlled device and receives an event from the controlled device.

The controlled device is a device that performs a predetermined function at the request of the control point, and transmits the requested event to the control point that requested the event when the state is changed.

Such configured UPnP network devices perform an advertisement process, a discovery process, a description process, a control process, and an eventing process.

Specifically, the advertisement process is a process in which a new controlled device is connected to a home network and informs other devices on the home network of the new controlled device. The discovery process is a process in which a new control point is connected to a home network to search for controlled devices operating on the home network. Description describes a process of parsing a service description XML file or a device description XML file through the IP address of the controlled device searched to control the controlled device by the control point Parsing) is a process to grasp the function of the newly added device in more detail. In the control process, when the control point desires to provide a specific service through the controlled device, a control message requesting a predetermined service using SOAP is transmitted to the controlled device according to the UPnP device architecture, And a response message (result, variable value) is received. The eventing process is a process of confirming the information change state of the controlled device that has provided the predetermined service by the control command transmitted from the control point.

[0004] UPnP telephony technology capable of communicating received call data to a device in a home based on the UPnP technology and allowing a user to make a call using the home network device is being studied. According to the UPnP specification, the UPnP telephony architecture is composed of a telephony terminal that receives a telephone call from outside, an in-home electronic apparatus that receives telephone data from the telephony terminal, and a control point that controls the two devices. The control point can control the functions of the telephony terminal and the electronic device using a network, and is responsible for connection between the two devices and establishing a media session. The telephony terminal that receives the telephone is a telephony server, and the telephony device that receives telephone data from the telephony server is a telephony client. The telephony control point performs control to transfer the received telephone call to the telephony server to the telephony client.

In the telephony service, a phone book data model is used to manage information such as contacts. The phone book data is managed by the telephony server. When specific data in the phone book is changed, the telephony server receives an event notification for data change of the phone book to the telephony control point. In order to receive the event notification, the telephony control point must perform event subscription.

As described above, all the telephony control points using the UPnP telephony service receive the event notification when the data of the phone book in the telephony server is changed. In other words, the telephony server always operates to forward event notifications to all telephony control points. Therefore, some of the telephony control points may unnecessarily receive event notifications even when the contacts are changed regardless of their own.

Also, since the data of the phone book in the telephony server is shared by all the telephony control points, it is possible for a specific telephony control point to arbitrarily modify and delete the data of the phone book. Therefore, there is a problem that a specific contact can be modified or deleted by malicious or mistaken by another user.

The present invention provides a method of managing data of a phone book by control points and giving access rights to other users according to a policy set by a user, and also provides an event reservation (event subscription) to provide a way for a telephony control point to receive only event notifications for data changes of interest. To this end, in order to provide event notification for each client, a specific field is added to a phonebook data model when a service subscription procedure is performed to define an event state for each user. Also, by defining the ownership of the contacts in the phonebook and the setting method of the usage rights of other users for each client, individual event notification for a specific client is enabled.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a home network system for providing a telephony service to which the present invention is applied.

1, a home network system according to an exemplary embodiment of the present invention includes a service provider 110, a UPnP telephony control point (hereinafter, referred to as a TCP) 130, a telephony server (TS) 120, and a telephony client (TC)

The service provider 110 provides a telephony service and provides an interface to the telephony server for sending and receiving a call.

The UPnP telephony control point 130 is a logical software module that controls a telephony server device (Telephony Server Device) and a telephony client device (UPnP Action) using a UPnP action.

The UPnP telephony control point 130 uses the capability information of the call data transfer agent included in the telephony server 120 or the telephony client 130 received from the telephony server 120 and the telephony client 140 to use And determines an optimal media format transmission protocol. The UPnP telephony control point 130 generates a profile in which the determined media format and transmission protocol are defined and transmits the created profile to the teleponie server 120 and the telephony client 140, Set the environment of the included call data transfer agent.

The UPnP telephony control point 130 may be included in the telephony server 120 or the telephony client 140 and may be independently included in a physical device such as a PC (Personal Computer) or a PDA (Personal Digital Assistant).

If the UPnP telephony control point 130 is included in the telephony server 120 or the telephony client 140, the UPnP telephony control point 130 may not directly use the UPnP action on the network, The device can be controlled. In this case, the control method may have various forms depending on each implementation.

The telephony server 120 includes a software-configured telephony server device, which is constituted by a physical device such as a PC including a Voice over IP (VoIP) composed of a communication device such as a cellular phone or a telephone and software. Also, the telephony server 120 controls call transmission / reception using a service provider 110 providing a telephony service and an interface provided by the service provider.

The telephony client 140 includes a physical device including a function of inputting and outputting a user's voice or image, such as a PC, a TV, and a mobile communication terminal, and includes a telephony client device configured by software. The telephony control point 130 and the telephony client 140 are devices that perform separate functions or the telephony control point 130 is mounted on the telephony client 140 according to the type of the telephony client 140 I will. That is, it is possible to physically perform each operation in one device, and it is assumed herein that the telephony client 140 and the telephony control point 130 are physically configured in one device for ease of explanation.

2 is a diagram illustrating an example of a data structure of a phone book according to an embodiment of the present invention.

Referring to FIG. 2, an Interface item represents a network interface for a telephony service. Namely, WiFi, Bluetooth, and WCDMA.

Setting describes the service setting information for the telephony service. The setting method includes an alarm method for the received signal such as bell / vibration / silence, a ring tone selection, a missed message, and the like.

Address book describes actual contact information. In the present invention, additional attribute information is additionally defined for each contact information.

Table 1 is an example of a data model of an address book including attribute information described in the present invention.

Name Type ACC EOC Owner Preference Acc right. / UPnP / PHONE / AddressBook / Contact / # / MultiInstance W

The Name in Table 1 indicates the name of the actual contact, and Type indicates the representation type of Name. That is, it is possible to create a contact with multiple objects. Only one identification for each contact is created, and the Nick name of the identification must be written as a String. In addition, ACC expresses read and write information for each contact of each item. That is, it indicates whether the field of the Name is writable or read-only. EOC represents whether to generate an event when the data is changed.

In the present invention, Onwer, Preference and Acc right are newly defined as attribute information for each contact in addition to ACC and EOC. The owner indicates the owner who generated the contact information when generating the contact information. Acc right indicates information about the access rights of others, other than the owner of the contact, when the data needs to be modified. That is, in addition to the owner who created the contact, it can indicate whether the other person can modify the contact, whether the contact can be read only, or not.

The ACC is fixed to the attribute information of the address book since it is the readable and writable information about the data of the corresponding item, whereas ACC right means the read and write permission information about the created data. Can be set. Preference is to indicate the device or user information to be notified about the modified information when the contact is modified. That is, the user registered in the preference receives, from the telephony server, the fact that the contact information is modified when the contact information is modified.

Table 2 shows an example of the address book for the contact information newly created by the user A through the address book data model shown in Table 1 above.

Name Type ACC EOC Owner Preference Acc right. Contact 1 One User A User A, User B Read only Contact 2 One User A User A Owner only

Referring to Table 2, since Contact 1 and Contact 2 are generated by User A, Owner is set to User A. When EOC is set to 1, event notification is performed to the subscribed telephony control point that reserves the event notification when data change of Contact 1 and Contact 2 occurs. User A is set to be readable by other users for Contact 1, and only User A can be read and written for Contact 2. If contact 1 is changed, it means that only user A and user B receive event notification about data change. If contact 2 is changed, only user A receives event notification.

By adding new attribute information for the contact, the user solves the problem that the contact can be arbitrarily modified by others by specifying ownership for each contact. Also, by providing subscriptions to event notifications for each contact, there is no need for the user to receive event notifications for data changes that are not of interest or need not be known.

3 is a flowchart illustrating an event notification operation of a telephony service according to an exemplary embodiment of the present invention.

3, it is assumed that the telephony service system of the home network is composed of a telephony server (hereinafter referred to as TS) 34 and three telephony control points (denoted by TCP hereinafter) 31, 32 and 33 do. The TS 34 manages phone book data.

In step 310, the second TCP 32 and the third TCP 33 perform a subscription for a phone book event notification to the TS 34. At this time, the second TCP 32 reserves the data change of the user a at the time of reservation, and the third TCP 33 reserves the data change of the other users except the user a.

If the first TCP 31 corrects the data of the phone book by the user a in step 320, the TS 34 modifies the data of the phone book in step 330 and stores a state variable for the data of the user a Update. Conventionally, when a state variable is changed, an event notification for data change is transmitted to all TCP subscribed to the telephony service. However, since the present invention provides a subscription for specific data, the state variable for the data change of the user a is updated and only the second TCP 32 reserved for the data of the user a Notify.

In the present invention, a method of managing a state variable is described so that an event notification can be received for each TCP subscribed to specific data as described above. In the present invention, a state variable for specifying the data change of the phone book is specified as ConfigurationUpdate. ConfigurationUpdate is configured in the format shown in Table 3 below.

ConfigurationUpdate Version TimeStamp 379 2007-10-24T05: 41: 00

The present invention proposes a method of managing a plurality of state variables by TCP or specific data as one embodiment of state variable management.

The method of managing state variables for each TCP is to create and manage state variables for each TCP reserved for the telephony service. In this case, the status variable is "TCP2.ConfigurationUpdate", "TCP3.ConfigurationUpdate".

A method for managing state variables for specific data is a method of creating and managing state variables for specifying that the telephony server has changed data of a specific user among phone book data of a telephony server. The telephony server manages the TCP to receive the corresponding status variable and the status variable by binding as shown in Table 4 below.

State variable TCP list dataA.ConfigurationUpdate TCP 1, TCP 2 dataZ.ConfigurationUpdate TCP 3

4 is a flowchart illustrating an example of an event notification operation of a telephony service according to an exemplary embodiment of the present invention.

The event notification operation of the telephony service according to an embodiment of the present invention will be described with reference to FIG. First, in step 410, the second TCP 32 and the third TCP 33 perform a subscription for the telephony service. In this case, the second TCP 32 reserves the data of the users a and b, and the third TCP 33 reserves the data of the users b and c.

In step 420, the TS 34 generates a status variable for the event reservation of the second TCP 32 and the third TCP 33. At this time, since the second TCP 32 and the third TCP 33 reserve the different data, the status variable is generated for each TCP according to an embodiment of the present invention. That is, the second TCP 32 is bound to the second state variable, and the third TCP 33 is bound to the third state variable.

In step 430, the first TCP 31 transmits a message to the TS 34 to add a new contact owned by the user a.

In step 440, the TS 34 adds the data of the contact addition message received from the first TCP 31 to the phone book.

In step 450, since the user a data has been changed, the TS 34 updates the second state variable related to the data of the user a.

In step 460, the TS 34 transmits an event notification to only the second TCP 32 bound to the second state variable.

In step 470, the second TCP 32 receives the second status variable as an event for data change of the user a reserved by the second TCP 32, and requests the updated data.

In step 480, the TS 34 transmits the updated data to the second TCP 32.

The present invention proposes a method for managing a state variable and changing a format of a conventional state variable while managing only one state variable for a telephony service.

The format of the state variable according to another embodiment of the present invention is shown in Table 5 below.

ConfigurationUpdate Preference Version TimeStamp TCP 1
TCP 2 379 2007-10-24 T05: 41: 00``

The Preference field in Table 5 indicates the ID of the control point to which the event notification should be transmitted. When changing the data of user a, the telephony server sends the event notification to all telephony control points by adding the ID of the telephony control point that made the reservation for data change of user a to the preference field. At this time, the telephony control point checks the preference field of the received state variable and, if the ID of the teleport control point itself is included, transmits a request for the changed data to the telephony server. The telephony control point ignores the event notification if its ID is not included in the received state variable.

5 is a flowchart illustrating an event notification operation of a telephony service according to another embodiment of the present invention.

An example of an event notification operation of the telephony service according to another embodiment of the present invention will be described with reference to FIG. In step 510, the second TCP 32 and the third TCP 33 respectively schedule events for the telephony service. The second TCP 32 performs event reservation for the data of the users a and b, and the third TCP 33 performs the event reservation for the data of the users b and c.

In step 520, the first TCP 31 transmits a message for adding a new contact owned by the user a to the telephony server.

In step 530, the TS 34 adds the data of the contact addition message received from the first TCP 31 to the phone book data.

In step 540, since the data of the user a is changed at the same time, the TS 34 updates the state variable by adding the ID of the second TCP 32 that has made the event reservation to the data of the user a to the preference field of the state variable.

In step 550, the TS 34 transmits the updated state variable to all the TCPs that have made the reservation.

In step 560, the second TCP 32 and the third TCP 33 respectively check the preference field in the state variable after receiving the state variable to check whether the ID of the telephony control point itself is included.

In step 570, the second TCP 32 confirms that its ID is present in the preference field in the state variable and requests updated data. The third TCP 33 confirms that there is no ID in the preference field in the status variable and ignores the event notification.

In step 580, the telephony server transmits the updated data to the second TCP (32).
