Problems solved by technology

[0012] The purpose of the present invention is to provide a method for determining the quality of service QoS strategy to solve the problem in the prior art that when there are multiple QPHs in the network, only the QoS strategy of the QPH specified by the CP or the default QoS strategy can be used as the new media flow QoS strategy, but can not choose a better QoS strategy

Embodiment 1

[0047] Embodiment 1: This embodiment adopts the technical solution of determining the QoS policy holder according to the information of the QoS policy holder in the network, wherein the information of the QoS policy holder includes: the latest QoS policy holder policy Modification time, the time when the QoS policy holder accesses the network, the total time when the QoS policy holder is selected to access the network, the priority of the QoS policy holder, etc.

[0048] When the CP sends a QoS request to the QM, the QM first judges whether there is a QoS policy holder in the network: if there is no QoS policy holder, the default QoS policy is used; if there is only one QoS policy holder in the network, the policy is used to hold The owner's QoS policy; if there is more than one policy holder in the network, select the QoS policy holder according to the following scheme:

[0049] First, in the UPnP QoS architecture defined in the UPnP Device Architecture Framework, the functio...

Embodiment 2

[0074] Embodiment 2: After a QPH is determined by adopting the method shown in Embodiment 1, the QM does not directly adopt the determined QPH strategy, but synchronizes all other QPHs in the network according to the determined information of the QoS policy holder. The policy of the QoS policy holder makes the policies of all the policy holders in the network the same, so that any policy holder can be selected.

[0075] In the following, it will be explained in detail that in this embodiment, the expansion of the service function of the QoS policy holder and the setting of information elements are the same as those in Embodiment 1. As described in Embodiment 1, according to the policy information of each QPH, the newly created After the media stream provides the QPH of the QoS policy, according to the policy synchronization of all QPH policies in the network, the function of the QPH service needs to be expanded first, and the reading and setting of the policy are added on the b...

Embodiment 3

[0095] Embodiment 3: The QoS policy holder is determined according to the QoS policy holder selected and used in the network and the user level.

[0096] When the CP sends a QoS request to the QM, the QM first judges whether there is a QoS policy holder in the network: if not, the default QoS policy is used; if there is only one QoS policy holder in the network, the policy is used to hold The owner's QoS policy; if there is more than one policy holder in the network, select the QoS policy holder according to the following scheme:

[0097] 1. If the CP does not specify a QoS policy holder, check whether there is a selected QoS policy holder among all the policy holders in the network, if not, according to the information of each policy holder in the network Select a strategy holder to provide QoS strategy for the new media flow, if there is a selected strategy holder, use the QoS strategy of the selected strategy holder as the QoS strategy for the new media flow;

[0098] 2. I...

Abstract

The present invention discloses a determining service quality QoS strategy method. Said method includes 1, extending QoS strategy holder service function, increasing information element recording QPHinformation; 2, when control point CP sends out QoS request to QoS supervisor, QM determining as new build media stream providing QoS strategy QPH according to said information element recorded QPH information, providing QoS strategy for new build media stream according to defined QPH QoS strategy. The present invented technical proposal makes media stream obtain fine quality assurance.

Description

technical field [0001] The present invention relates to the technical field of QoS (Quality of Service), more specifically, to a method for determining the QoS strategy of UPnP (Universal Plug and Play) devices in a home network. Background technique [0002] With the development of digital technology, UPnP (Universal Plug and Play) technology has begun to be applied to more and more home devices, such as UPnP AV (Audio Video audio and video) equipment media servers and media presentation devices, UPnP printing devices and UPnP gateway devices, etc. Applying UPnP QoS (Quality of Service) technology in the network can well ensure that the above-mentioned UPnP devices work normally in the home network and provide users with a better quality service experience. For example, transmission in the network requires high real-time For strong media streaming (including audio, video, sound, and games, etc.), the application of UPnP QoS technology can reduce delay and jitter and improv...
