Control method and equipment for accommodating and releasing resource

Abstract

The invention discloses a method for controlling resource accepting. The method comprises the steps as follows: a service provision request message sent by a client side is received, and the services comprise unicast service and multicast service; a service label is picked up from the service provision request message; resource required by the service is confirmed according to the service label; and the resource required by the service is compared with the current usable resource to control whether to accept the corresponding service provision request or not. The invention also discloses a resource accepting control device, a resource release control method and a device thereof. The invention can realize the uniform accepting and release control on the user resource of the unicast serviceand the multicast service.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for controlling resource admission and release. Background technique [0002] Such as figure 1 As shown, a typical access network networking includes: CPE (customer premise equipment, user end equipment), such as PC personal computer, STB (set top box, set-top box), etc.; AN (access node, access node), with the implementation The function of user access can provide users with various access methods, such as various DSL access, wireless access, optical access, etc.; Aggregation Network (aggregation network), used to aggregate the traffic of each AN in the uplink direction to Core network, which distributes the traffic from the core network to each AN in the downlink direction; BNG (broadband network gateway, broadband network gateway), has the function of converging user traffic and providing user-based policy control; Core Network (core network...

Problems solved by technology

[0013] Since the audio and video services are very sensitive to the network packet loss rate, a serious packet loss rate will cause the user equipment to fail to successfully decode the received audio and video content, resulting in service unavailability

One possible situation is that when the user bandwidth is limited, the user already has multicast audio and video transmission, and initiates a unicast audio and video transmission request. If the remaining bandwidth cannot meet the bandwidth requirements of the newly requested unicast audio and video , then continuing to transmit unicast audio and video will lead to the average discarding of all audio and video (including unicast and multicast) data on the AN, resulting in the unavailability of all audio and video services; otherwise, there are unicast audio and video services first, and the user initiates The same is true for multicast audio and video services
