Embodiment Construction

[0034] Detailed reference is now provided to embodiments of the invention. The following embodiments will be described in order to explain the present invention by referring to the figures.

[0035] Figure 2 shows a description of static multiplexing. For VBR streams, the delay variation should be well controlled to meet the mobile TV channel switching requirements of 3GPP SA1. Therefore, the allocation of bandwidth resources for VBR will be around the maximum bit rate instead of the average bit rate, thus causing a waste of bandwidth resources. If several VBR streams are multiplexed together, it can be found that the multiplexed bit rate variation is greatly reduced, so that the bandwidth resource allocation is more close to the average bit rate. This is the multiplex statistical multiplexing gain. From the point of view of user experience, the video quality setting of the multiplexed VBR streaming service is better than that of the unmultiplexed CBR streaming service. Th...

Abstract

The invention relating to the field of mobile communication provides an eNB packet discarding method. The method comprises checking the current packet and bandwidth resources, determining whether usable bandwidth resources exist in the current scheduling period or not for transmitting packets; if not, packets being not allowed to be transmitted in the current scheduling period, and the packets buffered to the next scheduling period until usable bandwidth resources exist; if so, delay calculation being performed by program scheduling before the next transmitting moment; if the packet value dose not exceeds the transmission threshold value after delaying, performing cascade connection to the packet and the subsequent packet; if the packet value exceeds the transmission threshold value after delaying or usable bandwidth resources still not exist after the transmission of the delay packet, discarding the packet. Comparing with an NSN scheme, less data is discarded by using the method, therefore, less bandwidth resources are needed to provide a same packet discarding rate.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the multimedia broadcast and multicast services in which the 3GPP LTE standardization process is in progress. Background technique [0002] With the rapid development of mobile communication technology, the widespread use of mobile communication networks and the rapid growth of the number of mobile communication users, the realization of MBMS (Multimedia Broadcast and Multicast Service) in mobile communication networks has become an important part of the development of mobile communication systems. one of the hotspots. In order to realize the broadcast multicast technology in the mobile communication system, the third generation mobile communication standardization organizations 3GPP and 3GPP2 have started the research and protocol formulation in this area, and put forward the corresponding design goals: occupied radio access network and core The bandwidth resource of the net...
