Problems solved by technology

[0003] However, the use of link layer multicast in the prior art requires the support of network elements in the mobile network, and when only unicast is used for video transmission, it cannot meet the burden on the backhaul network when users watch high-definition videos at the same time. Watching high-definition videos in high-concurrency scenarios has high bandwidth requirements, and the network bandwidth occupied by playing videos increases rapidly, which will seriously affect the bandwidth requirements of other data services in the network

Abstract

The present application provides a method and device for distributing multimedia services, which relate to the field of wireless communication technology, meet the bandwidth requirements for users to watch high-definition videos under high concurrency conditions, and provide users with better video playback service experience. The method includes: the MEC platform receives a multimedia service request carrying a domain name sent by a client terminal, and sends the multimedia service request to a multimedia application platform corresponding to the domain name; the client terminal generates a redirection request according to the first redirection request sent by the multimedia application platform. Directed multimedia service request; the MEC platform judges the redirected multimedia service request, if the redirected multimedia service request carries the first unicast URL, then sends the data packet corresponding to the first unicast URL to the client terminal, if the redirected multimedia service If the request carries the first unicast URL and the preset multicast address, a data packet corresponding to the first unicast URL is sent to the preset multicast address.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for distributing multimedia services. Background technique [0002] With the rise of ultra-high-definition video services represented by 2K / 4K video, virtual reality (Virtual Reality, VR) and augmented reality (AugmentReality, AR), video services have now become an important part of operators after voice, SMS and data services. The fourth basic business. Video services have high requirements on the network, including: high bandwidth, low delay, low packet loss rate, and high concurrency rate. At present, unicast or link layer multicast is usually used for live video, video on demand, video conferencing, real-time Video transmission such as video surveillance. [0003] However, the use of link layer multicast in the prior art requires the support of network elements in the mobile network, and when only unicast is used for video tr...
