A universal plug and play (UPnP) network is provided. In the UPnP network, a QoS policy holder of a UPnP QoS architecture manages information on QoS modes that are previously set, and a QoS manager controls QoS devices by importing traffic policies for a predetermined QoS mode from the QoS policy holder. Accordingly, a user can suitably control traffic items in the network only by selecting a desirable QoS mode according to situations.
Description
Description METHOD AND APPARATUS FOR CONTROLLING QUALITY
OF SERVICE IN UNIVERSAL PLUG AND PLAY NETWORK
Technical Field
[1] The present invention relates to a home network, and more particularly, to a method of controlling Quality of Service (QoS) of a service provided by devices in a universal plug and play (UPnP) network. Background Art
[2] Universal plug and play (UPnP) is a protocol capable of finding and controlling electric appliances connected to a network. UPnP is used as a standard technique of home networking.
[3] The UPnP QoS architecture is a standard for securing QoS for services in the network by controlling traffic communicated among a plurality of devices in the UPnP network. Services such as QoS device services, QoS policy holder services, QoS manager services, and the like are defined in the UPnP QoS architecture. The UPnP QoS architecture is used to use multimedia contents such as audio and video through a network.
[4] FIG. IA illustrates a UPnP network constructed with a device for providing a QoS device service (hereinafter, referred to as a QoS device), a device for providing a QoS policy holder service (hereinafter, referred to as a policy holder), and a device for providing a QoS manager service (hereinafter, referred to as a QoS manager). A user previously sets and stores a traffic policy (for example, priority) in a network in the policy holder. When a control point requests QoS for predetermined traffic to be secured, the QoS manager constructs a traffic descriptor by receiving traffic policy information and controls traffic of the QoS devices by using the traffic descriptor.
[5] FIG. Ib is a flow diagram for illustrating a procedure in which UPnP QoS architecture elements communicate with one another.
[6] The control point transmits information on traffic to which QoS is to be applied to the QoS manager by calling an action of RequestTrafficQos() of the QoS manager service. The transmitted information may include types of source devices, sink devices, and traffic.
[7] The QoS manager acquires a traffic policy by calling an action of GetTrafficPolicyO defined in the QoS policy holder service based on the transmitted information. The traffic policy indicates information for controlling QoS for the traffic such as an admission policy, a traffic importance number, a user importance number, and the like. Since a detailed description of information constituting traffic elements is included in
UPnP QoS architecture document, a detailed description thereof will be omitted. On the other hand, the QoS manager calls the actions of GetPathInformation(), GetQoS- Devicelnformation(), and GetQoSState() defined in the QoS device service so as to recognize a path of the traffic and capability of devices located on the path of the traffic.
[8] Finally, the QoS manager controls traffic of the QoS devices by calling an action of
SetupTrafficQos() of the QoS device services based on the gathered information.
[9] In the existing technique, since a traffic policy has to be set, there is a problem in that it is impossible to flexibly control the traffic of the network for different situations and different users. For example, when a user sets a priority level of video traffic transmitted from a media server located at an upstairs room to a television (TV) in a living room to the highest priority level, the video traffic has the highest priority level regardless of the situation, if a traffic policy for the video traffic is not changed. However, as an example, QoS of video traffic of a drama transmitted from a set-top box in the living room to a kitchen has to be previously set to coincide with a time for preparing a dinner. In a case where an urgent report has to be printed, data traffic transmitted to a printer is most important for the user. The existing technique is inconvenient because traffic policies have to be changed in the aforementioned cases. Disclosure of Invention Technical Solution
[10] The present invention provides a method and apparatus for flexibly controlling traffic of a QoS manager service in a network based on various QoS modes that are previously set by a user. Advantageous Effects
[11] According to embodiments of the present invention, it is possible to suitably control traffic of the network in various situations only by selecting a desirable QoS mode without modifying each traffic policy by a user in a UPnP network. Description of Drawings

[48] In operation 405, the control point calls an action of RequestModeQoS() of the QoS manager service so as to set the traffic items of the network to a predetermined QoS mode. [49] In operation 406, the QoS manager calls an action of GetModeTrafficPolicyO of the
QoS policy holder service so as to acquire traffic policies of the requested QoS mode. [50] In operation 407, the QoS policy holder returns the traffic policies that are set for the
QoS mode. [51] In operation 408, the QoS manager controls QoS devices based on the traffic policies that are set for the QoS mode. [52] In the aforementioned procedures, BrowseQoSModes(), EditQoSMode(), Re- questModeQoSO, and GetModeTrafficPolicyO are newly defined actions according to the embodiment of the present invention. [53] FIG. 5 illustrates a structure of a device 500 for providing a QoS manager service and a structure of a device 550 for providing a QoS policy holder service in a UPnP network according to an embodiment of the present invention. [54] The QoS manager 500 includes a QoS request receiver 501, a policy information acquirer 502, and a QoS controller 503. The QoS request receiver 501 receives a request for controlling traffic based on a predetermined QoS mode from a control point
510. At this time, an identifier for the QoS mode is input. [55] The traffic policy acquirer 502 imports the traffic policies that are previously set for the QoS mode from the QoS policy holder 550 by using the identifier. [56] The QoS controller 503 controls traffic of a UPnP network by controlling QoS device services 520 based on the traffic policies transmitted from the traffic policy acquirer 502. [57] The QoS policy holder 550 includes a traffic policy request receiver 551, a traffic policy provider 552, a storage unit 555, a mode information provider 553, and a mode information editor 554.
[58] The traffic policy request receiver 551 receives a request for traffic policies for a predetermined QoS mode from the QoS manager 500. At this time, an identifier for the
QoS mode is received as an input parameter. [59] The traffic policy provider 552 reads mode information of the QoS mode from the
storage unit 555 in which information on traffic policies is stored by using the identifier. As described above, the mode information includes traffic policies of the QoS mode.
[60] On the other hand, a user can browse mode information for all the QoS modes that are previously set by using any control point 530 in a UPnP network. The mode information provider 553 provides mode information stored in the storage unit 555 to the control point 530, in response to a request from the control point 530.
[61] In addition, the user can edit the mode information stored in the storage unit 555 by using any control point 530 in the UPnP network. At this time, in order to prevent non- authorized users from modifying mode information, an authentication procedure may have to be passed. The mode information provider 553 generates a new QoS mode, or modifies or deletes mode information of the QoS mode that is previously set, in response to a request from the control point 530.
[62] The embodiments of the present invention can be written as computer programs and can be implemented in general-use digital computers that execute the programs using a computer readable recording medium.
[63] Examples of the computer readable recording medium include magnetic storage media (e.g., ROM, floppy disks, hard disks, etc.), and optical recording media (e.g., CD-ROMs, or DVDs).
[64] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. The exemplary embodiments should be considered in descriptive sense only and not for purposes of limitation. Therefore, the scope of the invention is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present invention.
