Problems solved by technology

At present, the QoS control of streaming media services in the existing technology mainly adopts the method of reserving fixed bandwidth in advance for streaming media service categories. The problem with this method is that the strategy is single and rough, and it cannot target different users, different UEs and different streams. Media service QoS requirements to achieve targeted QoS policy control

Embodiment Construction

[0064] The basic idea of ​​the present invention is: after the Tracker receives the UE's service request message, the Tracker or an intermediate network element notifies the access network through the RCF to reserve resources, and during this process, the RCF will generate a QoS policy and a default The TFT sends a policy enforcement request message to the resource enforcement gateway in the access network after receiving the notification that the resource reservation is completed; the resource enforcement gateway performs resource reservation after receiving the policy enforcement request message, and notifies the UE to create a bearer. In this way, QoS control on service media streams is realized.

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0066] Figure 4 It is a schematic ...

Abstract

The invention discloses a method for guaranteeing the service quality of a streaming media service, comprising: a tracking server Tracker receives a service request message of a user equipment UE, and triggers sending a list of candidate content cache servers to the UE; the UE selects at least one Notify the access network of the connection information of the content caching server; the access network modifies the bearer information according to the connection information, so that the UE and the target content caching server establish a media connection through the bearer, and through the media Connect for streaming. At the same time, the invention discloses a system for guaranteeing the service quality of streaming media business. The present invention realizes more flexible and refined streaming media QoS policy control, thereby meeting the QoS requirements of different users, different terminals or different streaming media content transmissions.

Description

technical field [0001] The present invention relates to a service quality guarantee technology in a peer-to-peer network based on an IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) network, in particular to a method and system for guaranteeing the service quality of streaming media services. Background technique [0002] Peer-to-peer (P2P, Peer to Peer) technology is a peer-to-peer interconnection or point-to-point technology. Compared with the traditional client / server (C / S, Client / Server) model, different Peer nodes in the P2P network directly exchange data or services without going through relay devices, and the status of each node is right Equal, with equal rights and obligations. figure 1 It is a schematic diagram of a P2P network, such as figure 1 As shown, in a P2P network, each node can either obtain services from other nodes or provide services to other nodes. Since P2P technology can greatly relieve the pressure on the server side in the traditional C / S a...
