Transmission method and system for multimedia content, and corresponding method, subscriber terminal and device

Abstract

The invention discloses a transmission method and system for a multimedia content, and a corresponding method, subscriber terminal and device. The transmission method includes that: a multimedia content distribution device determines an attribute value of the multimedia content, and sends the multimedia content containing the attribute value to a broadcast network; according to an attribute of the multimedia content, the broadcast network determines a broadcast priority of the multimedia content, and broadcasts the multimedia content which meets a specified requirement of the broadcast priority to the subscriber terminal; the subscriber terminal feeds access information of the own multimedia content back to a cellular eNB; the cellular eNB feeds the access information of the multimedia content back to the multimedia content distribution device; the multimedia content distribution device amends the corresponding attribute value of the multimedia content according to the access information of the multimedia content, and sends the amended attribute value of the multimedia content to the broadcast network, and then the broadcast network updates the broadcast and rebroadcasts. According to the invention, the load of a communication transmission pipeline caused by the increase of the service volume can be relieved, and the utilization efficiency of the system capacity is improved.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular to a method and system for transmitting multimedia content in which a cellular network and a broadcast network are integrated, and a corresponding method, user terminal and device. Background technique [0002] Through mobile networks, users can access a large amount of multimedia content from content distribution devices. At present, the data of these multimedia contents is mainly transmitted through the cellular network, but the rapid increase of the data volume brought by the rapid increase of mobile devices will cause a serious burden to the traditional cellular network. Studies have shown that among a large number of multimedia contents, only a small part will be requested by a large number of users, and most of the remaining multimedia contents will be requested by a small number of users. The potential technical advantages of the mobile broadc...

Problems solved by technology

[0009] Existing cellular-based mobile broadcast and multicast technologies, various pure broadcast single frequency network technologies do not provide uplink channels, and users cannot feed back multimedia usage information

Since the content distribution device cannot obtain the latest attribute information of multimedia content in time, it often uses the historical attributes of multimedia content for distribution, resulting in a low degree of conformity between the distributed and broadcast multimedia content and the actual access requirements of user terminals, so the utilization efficiency of system capacity Low, unable to maximize system capacity

If the cellular network is used to meet the actual access needs of user terminals, the load on the communication pipeline will be too large when the traffic volume increases, so the utilization efficiency of the system capacity is also low, and the technical problem that the system capacity cannot be maximized
