Method and device for distributing resource of real-time flow-media business

Abstract

The invention relates to a method of real-time flow media service distribution resource, wherein it comprises: the group data service node catches the flow media service report sent by user terminal; analyzing said report to judge the start of real-time flow media service, to initialize the refresh of data pack protocol PDP context, and perform resource for said real-time flow media service; judging the end of said service, to initialize the refresh of PDP context, and recycle the preformed resource. The invention also provides a relative device, which comprises: a detecting / analyzing module for catching and analyzing the service report sent from user terminal, a match judging module for matching the flow media service and the speed, and a resource manage module for performing relative resource for the real-time flow media service, based on the speed. The invention can confirm the service quality of flow media service and improve the network resource utilization.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for allocating service resources. Background technique [0002] The rapid development of data services, especially the development of real-time data services (such as streaming media services), has brought a great impact on existing networks. Real-time data services have a large amount of data and require low latency, which is a big test for traditional data networks. With the growth of real-time data services, the following requirements are put forward for the existing network: the network can distinguish real-time services from non-real-time services, that is, it can have service awareness capabilities; it can perform differentiated processing on perceived real-time services, That is, it has the ability to handle business differentiation. It can be seen that the service awareness capability is a prerequisite for guaranteeing the quality of service (Qualit...

AI Technical Summary

Problems solved by technology

[0006] 1. The network side cannot actively perceive the real-time streaming media service requested by the user, so it cannot dynamically allocate and reclaim the corresponding resources for the requested streaming media service

[0007] 2. The network side cannot actively perceive the service attribute information of user service requests, and can only provide streaming media services by providing guaranteed bandwidth for all user services, which may cause waste of resources

[0008] 3. The correctness of the service quality request depends on the user terminal and the user terminal application to make correct service perception, QoS parameter mapping and service application, which is too dependent on the user terminal and the user terminal application layer, so it may be due to the limited capability of the user terminal, resulting in The reported information is inaccurate, causing the service quality of real-time services to not be guaranteed

[0011] In the service-aware solution proposed in the 3GPP R6 protocol standard, due to the large number of types of user terminals and application software in the existing network, and the inconsistent QoS capabilities of user terminals, the current broadband code division multiple access system (Wide-band Code Division Multiple Access, WCDMA) network end-to-end service quality is difficult to guarantee

However, this solution has the following disadvantages: non-standard protocol is used, the protocol interaction is complicated, and the supporting support of GGSN, PDF and streaming media server is required, and the project implementation is relatively difficult
