Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0027] In the simulation test environment, test the eMBMS service performance in a synchronous network composed of 21 cells. The wireless network transmission bandwidth is set to 10MHz, the central frequency band of transmission is 2.5GHz, and the area of ​​this synchronous network is 12.34km 2 , assuming that the transmit power of the eNB is 43dBm, the spectral density of the noise is -174dBm / Hz, and there are 50 registered users in each cell. Assume that the proportion of users interested in each multimedia content in a cell is figure 2 As shown (in this embodiment, there are four multimedia contents, which are respectively marked as s1-s4).

Abstract

The invention discloses a multimedia broadcast multicast service network configuration method based on an LTE-A system. A multimedia broadcast multicast service in an LTE-A system proposed on the basis of 3GPP comprehensively considers that multiple hot spot information exist in the whole network and are different in ranges, configuration of MBSFN can influence signal to interference plus noise power ratio of a user, the rest network resource after the multimedia broadcast multicast service is configured can be used for providing factors such as a unicast service, and a multimedia broadcast multicast service network configuration method which can be based on the application scenarios, meets video-on-demand of the user and optimizes network throughput under an LTE-A protocol frame is provided.

Description

technical field [0001] The invention relates to an LTE-A system-based multimedia broadcast multicast service network configuration method, and belongs to the technical field of LTE-A cellular mobile network transmission. Background technique [0002] 3GPP (Third Generation Partnership Project) LTE-A (Late Evolution of Long Term Evolution Network) mobile communication network is a 4G technology confirmed by the International Telecommunication Union Radiocommunication Sector (ITU-R) to meet the requirements of IMT-Advanced. The technology is designed to provide mobile users with faster data transfer rates and more stable and reliable network performance. Multimedia Broadcast Multicast Service (MBMS) is an important part included in the 3GPP LTE / LTE-A protocol. This service is mainly aimed at hotspot information in the cellular network, using the same data from multiple adjacent data sources (base stations). The method of synchronously transmitting the hotspot information to m...
