Problems solved by technology

If network throughput is used to measure the effect of eMBMS network configuration, users in MBSFN will not receive interference signals emitted by eNBs in the area, but will receive interference signals emitted by eNBs outside the MBSFN, so the MBSFN network The choice of also affects the user's signal-to-interference-noise ratio

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0038] Steps 1)-3) of the present invention are used to establish a model and set corresponding control variables and objective functions. Steps 4)-5) are to actually use the algorithm on the basis of the model, quickly coordinate the cells to establish the MBSFN network, and decide to configure the required broadcast content in the MBSFN network.

[0039] In this embodiment, in the simulation test environment, the eMBMS network configuration in a synchronous network composed of 57 cells is tested. 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 , with a total of 3420 regis...

Abstract

The present invention discloses a multimedia broadcast real-time network scheduling method based on a LTE system. Based on the multimedia broadcast multicast service in the LTE system provided by the 3GPP and through considering that there are many hot spot information in each district and different scenes of the hot spot information of each district, a method of rapidly configuring the multimedia broadcast multicast service network with low calculation and the information heat generated according to the real-time user video-on-demand requirement is provided under the LTE protocol frame. According to the method, the LTE system multimedia broadcast multicast service can rapidly optimize the network performances while satisfying the user video-on demand requirement.

Description

technical field [0001] The invention relates to a network configuration method required for multimedia broadcast and multicast services, and belongs to the technical field of LTE cellular mobile network transmission. Background technique [0002] 3GPP (Third Generation Partnership Project) LTE (Long Term Evolution) 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 protocol. This service is mainly aimed at hotspot information in the cellular network, and uses the same spectrum resources from multiple adjacent data sources (base stations) to synchronize to the network The method of transmitting hotspot information among multiple...
