Problems solved by technology

Therefore, communication resources of the first network reserved for giving high priority to communication will be wasted
[0006] However, there are no conventional techniques for achieving consistent QoS control across multiple networks

[0052] figure 1 An overview of the communication system 100 according to the first embodiment is shown. The communication system 100 includes a wide area network (WAN) 110, which may be, for example, the Internet. A user equipment (UE) 120 serving as a first communication means and a service providing server (SPS) 130 serving as a second communication means are connected to the WAN 110 . UE 120 and SPS 130 may communicate with each other via WAN 110 .

[0053] WAN 110 includes Application Server (AS) 111 , Policy Decision Function (PDF) 112 and Policy Enforcement Function (PEF) 113 . The AS 111 is configured to periodically obtain device-related information of the UE 120 , for example, the device-related information indicates the capabilities and presence status (presence status) of the UE 120 . In some cases, AS 111 is also configured to act as a proxy server passing communications between UE 120 and SPS 130 .

Abstract

The present invention generally relates to nodes and methods for Quality of Service (QoS) control. The present invention particularly relates to, but is not limited to, techniques for implementing QoS control for communications based on protocols such as Hypertext Transfer Protocol (HTTP) that do not mandate the use of Session Description Protocol (SDP) messages.

Description

technical field [0001] The present invention generally relates to nodes and methods for Quality of Service (QoS) control. The present invention particularly relates to, but is not limited to, techniques for implementing QoS control for communications based on protocols such as Hypertext Transfer Protocol (HTTP) that do not mandate the use of Session Description Protocol (SDP) messages. Background technique [0002] Currently, services such as Voice over IP (VoIP) communication services and video streaming services are widely distributed. Since such services are delay sensitive, it is important to provide appropriate quality of service (QoS). [0003] WO2007 / 045278 proposes mechanisms to ensure quality of service interoperability between two or more networks. According to WO2007 / 045278, the media types described in SDP messages are mapped to UPnP traffic type values, which correspond to the priority of traffic in a Universal Plug and Play (UPnP) network. [0004] However, ...
