Problems solved by technology

[0015] (1) Large service delay: mainly reflected in the fact that the underlying protocol of the GPRS backbone network is not suitable for real-time continuous streaming media service transmission, and the tunnel protocol GTP (GPRS Tunnel Protocol) actually adopted increases the transmission delay of media streams;
[0016] (2) Large network bandwidth cons...

Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0063] see figure 1 , the present invention is a mobile video-on-demand service system based on a GPRS network and performance optimization. The network elements in the network at least include: a mobile switching center MSC / VLR, a GPRS service support node SGSN (Serving GPRS Support Node), a GPRS gateway Support node GGSN (GatewayGPRS Support Node), streaming media content server SCS, WAP portal server, base station system BSS and user mobile terminal MS; the improvement of the system is mainly: the connection between the GGSN in the network and the external packet data network PDN Set up a central cache proxy CCP server on the border, and then set up a user border cache proxy UECP server in each BSS system (that is, between BTS and BSC), and also set up a high-s...

Abstract

The mobile VOD business system with super performance based on GPRS mobile network comprises: besides traditional net element, a CCCP server on boundary of GGSN and PDN to release load for SCS and reduce bandwidth consumption between GGSN and SGS, a UECP server arranged in BSS that is between BSC and BTS to self-adaptive improve buffer hit rate based on buffer alternative strategy and ensure fast response to most user request, and a high-speed IP DL between CCP and UECP to transmit flow media content and construct two-stage buffer device with two proxy servers to bypass great media and reduce data flux and load for other link and eliminate the effect of VOD to network performance.

Description

technical field [0001] The present invention relates to a performance-optimized mobile video-on-demand service system and its implementation method. Specifically, it relates to a GPRS mobile network-based, performance-optimized mobile video-on-demand service system and its implementation method. The field of communication network technology. Background technique [0002] Mobile video on demand VoD (Video on Demand) using mobile terminals is an important mobile data service, which meets the needs of mobile users to watch video programs anytime and anywhere, and has a huge market potential. At present, China Mobile has provided mobile video-on-demand services in Shanghai, Zhejiang, Fujian and other provinces and cities using the GPRS (General Packet Radio Service) network. [0003] GPRS network is a 2.5 generation mobile communication network, it is based on the current GSM mobile communication network, mainly by adding GPRS service support node SGSN (Serving GPRS Support Nod...
