detailed description

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

One of the main ideas of the embodiments of the present application may include:

The access network device obtains a bearer setup request or a service update request sent by the core network device, where the bearer setup request or the service update request carries the video parameter of the mobile video requested by the user, and the access network device can calculate the video according to the video parameter. The quality evaluation value can directly perform service scheduling according to the video quality evaluation value, and the video quality detection and the service scheduling are all completed by the access network device, and the quality detection is completed before the mobile video is transmitted to the user terminal, without performing more with the user terminal. The second interaction improves the efficiency of video quality detection.

FIG. 1 is a flowchart of an embodiment of a mobile video quality detecting method according to an embodiment of the present disclosure, where the method may include the following steps:

101: The access network device acquires a bearer setup request or a service update request sent by the core network device.

The bearer setup request or the service update request is sent when the core network device detects the mobile video service request triggered by the user terminal.

The bearer setup request or the service update request carries a video parameter of the mobile video requested by the user terminal, which is obtained by the core network device from the video server.

With the development of network technology, especially the rise of 3G and 4G networks, the existing mobile networks are mainly composed of three major parts: core network, access network and user terminal.

The core network mainly refers to the user terminal and the access network, or the network that connects the access network with other access networks, and generally refers to the network part except the access network and the customer premises network. Mainly implements user authentication, location management, call connection control, and user information transfer.

The user terminal is connected to the core network through the access network, and mainly performs functions such as wireless access and information processing.

The access network mainly provides information processing and transmission guaranteed by QOS (Quality of Service) to users, and processing and transmission of user and network control information.

The device on the access network side mainly includes a wireless network device such as a base station. For example, in an LTE (Long Term Evolution) system, the access network device in this embodiment may refer to a base station eNodeB (evolved Node B). The device on the core network side mainly includes a network element device capable of realizing its function. For example, in the LTE system, the device on the core network side in this embodiment may include a Serving Gatway (S-GW) and a packet data gateway ( The core network device in this embodiment may specifically refer to a packet data gateway, the policy and the charging rule function, and the PWW, the policy and the charging policy function (PCRF), and the like. Units can be integrated into a packet data gateway, or they can be deployed separately and connected to a packet data gateway.

When the mobile video service of the user terminal is implemented, the core network side is connected to the video server, and the user terminal establishes a bearer to implement one or more service data stream transmissions with the core network device, specifically in the LTE system, with the packet data gateway. .

The bearer established by the user terminal and the core network device mainly includes a default bearer and a dedicated bearer. In this embodiment, the mobile video service is implemented on the basis that the user terminal and the core network device have established a default bearer.

When the default bearer has been established on the user equipment and the core network device, the user terminal can pass the default The application for the new service, such as the mobile video service request initiated by the user terminal in this embodiment. At this time, the core network device detects the mobile video service request of the user terminal, and may send a service update request to the access network to establish a new service with the user terminal.

However, when the default bearer cannot provide the QoS required by the new service, an additional bearer service is required, that is, a dedicated bearer is established to provide the service. Therefore, the core network device may also send a bearer setup request to the access network device to establish a dedicated bearer to provide a specific service for the new service.

Therefore, in the embodiment of the present application, the access network device may obtain a bearer setup request or a service update request sent by the core network device.

In the embodiment of the present application, the bearer setup request or the service update request is to implement the mobile video service, and the core network device may obtain the requested mobile video from the video server according to the user's mobile video service request. Therefore, the core network device can parse the video parameters from the mobile video and carry the video parameters in the bearer setup request or the service update request.

The video parameters may include video rate, audio rate, video frame rate, video resolution, and video encoding type.

Step 102: Obtain a video parameter carried in the bearer setup request or the service update request.

After obtaining the bearer setup request or the service update request, the access network device can obtain the video parameters carried by the access network device.

103: Calculate a video quality evaluation value of the mobile video according to the video parameter.

The access network device may calculate a video quality evaluation value of the mobile video, that is, a MOS (Mean Opinion Score) value, according to the obtained video parameter, to indicate the satisfaction of the user watching the video.

After the access network device calculates the video quality evaluation value, the user can select a better service scheduling mode according to the video quality evaluation value, especially when one access network device is connected to multiple user terminals, according to each user terminal. The corresponding video quality evaluation value is used for service scheduling to provide better service for the user terminal. For example, a user terminal with a lower video quality evaluation value may be configured with more resources, or resources may not be scheduled, and the saved resources may be scheduled to other user terminals. The specific service scheduling solution may be determined according to actual application conditions.

In this embodiment, the user terminal triggers a mobile video service request, and the core network device may establish a request or a service in the bearer sent to the access network device according to the video parameter of the mobile video requested by the user terminal. The video update parameter carries the video parameter, so that the access network device can obtain the video parameter from the bearer setup request or the service update request, and calculate a video quality evaluation value of the mobile video according to the video parameter, so that The video quality evaluation value is used for service scheduling, and the video quality detection and the service scheduling are all performed by the access network device, and the quality detection is completed before the mobile video is transmitted to the user terminal, and the user terminal does not need to perform multiple interactions with the user terminal; The network device waits for the time when the video quality evaluation value is sent by different user terminals, so that the video quality detection and service scheduling can be coordinated, and the video quality detection efficiency is improved.

Compared with the prior art, in order to provide a better video service, the user terminal needs to perform video quality evaluation according to video parameters periodically, for example, and send a video quality evaluation value to the access network device. In the example, the access network device obtains the video parameters and calculates the quality evaluation value, which does not require the user terminal and the access network device to interact multiple times, further reduces the number of interactions, and has high detection efficiency, and is completed before the mobile video is transmitted to the user terminal. Quality detection and service scheduling enable better service for user terminals, improving the effectiveness of detection and the efficiency of business scheduling.

When the access network device acquires the video parameter and detects the cell handover, the video parameter may be transmitted to the access network of the handover target cell. The device, of course, if the cell switching is performed, the access network device of the cell has calculated the video quality evaluation value, and may directly transmit the video quality evaluation value to the access network device of the handover target cell, so that no repeated calculation is needed. The detection efficiency is further improved.
