Method, device and system for distributing user bandwidth in Internet protocol television (IPTV)

Abstract

The embodiment of the invention discloses a method, device and system for distributing user bandwidth in Internet protocol television (IPTV). The method for distributing user bandwidth in IPTV comprises the following steps of: receiving a service request sent by user equipment; judging whether the required bandwidth of a service in the service request surpasses the current access bandwidth of the user equipment; if the required bandwidth of the service surpasses the current access bandwidth of the user equipment, sending a request on distributing the required bandwidth of the service to network access equipment; and receiving the bandwidth distributed by the network access equipment according to the request on distributing the required bandwidth of the service. By adopting the scheme, distribution of a large quantity of fixed-bandwidth resources to each IPTV user is not required, so that idling of the bandwidth resources can be reduced effectively and flexible distribution of the overall bandwidth resource of the system is realized. Under the condition that the overall bandwidth resource is not changed, services of higher levels can be realized or the user capacity of an IPTV system is further increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for allocating user bandwidth in network television. Background technique [0002] Internet Protocol Television (IPTV) is a new technology that combines the characteristics of telecommunication network, broadcasting network and Internet network, and can provide users with a variety of interactive services including digital TV. Based on the same physical connection, users can make phone calls, surf the Internet, watch TV, and enjoy integrated services such as data, voice, and video. [0003] In an existing implementation manner, an operator allocates a fixed bandwidth to a user when the user subscribes to an IPTV service. However, in practical applications, IPTV includes various business forms such as browsing, voice, standard definition, and high definition, and different service forms have very different requirements for network bandwidth.

Problems solved by technology

However, in practical applications, IPTV includes various business forms such as browsing, voice, standard definition, and high definition, and different service forms have very different requirements for network bandwidth. Any specific business will occupy the same bandwidth resources, resulting in a long period of idle bandwidth resources

On the other hand, services such as high-definition video have relatively high requirements for network bandwidth. Under the current condition of limited overall network bandwidth resources, it is difficult for the IPTV system to support higher-level services and higher user capacity.

[0004] IPTV is a multimedia service based on a broadband network. However, the bandwidth resources of the current basic broadband network are still limited. How to make better use of limited bandwidth resources and provide IPTV users with high-quality services has become the key to restricting the development of IPTV services.
