Embodiment Construction
[0028] The technical solutions in the implementation examples of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the application examples of the present invention. Apparently, the described implementation examples are only some implementation examples of the present invention, not all implementation examples. All other implementation examples obtained by persons of ordinary skill in the art based on the implementation examples in the present invention belong to the protection scope of the present application.
[0029] When a video service user is subjected to sudden interference from BE services, the signal-to-interference-noise ratio (SINR) of the video service user will fluctuate violently. The traditional solution is to increase the transmit power of the video service user through a power control mechanism to improve the user's SINR , however, the power control mechanism will be triggered frequently due to ...

The invention discloses an energy-saving interference shaping method in an ultra-dense Small Cell network applied to a video service, and belongs to the technical field of wireless network communication. The method comprises the following steps: for a user requesting the video service, through a base station serving the user, periodically detecting the signal to noise ratio of the user, and testing the signal strength received from a neighboring base station; when the signal to noise ratio of the user does not meet a service requirement, triggering an interference shaping mechanism; according to the interference signal strength, transmitting an interference shaping scale to an interfering base station; adjusting a transmission power by the interfering base station according to a QoE index of a BE (Best Effect) type service; repeating the interference shaping mechanism until the signal to noise ratio meets the service requirement or reaches a maximum number of iterations, and ending the interference shaping. The energy-saving interference shaping method in the ultra-dense Small Cell network applied to the video service provided by the invention reduces the burst interference of the BE type service in the ultra-dense Small Cell network in the video service introduction, and ensures the QoE requirement of the video service and the BE type service to some extent.
Description
technical field [0001] The invention relates to the technical field of wireless network communication, in particular to an interference shaping method for sudden interference of video services in an ultra-dense SmallCell network. Background technique [0002] With the advancement of mobile communication technology, the popularity of smart terminals, and the vigorous development of the mobile Internet and the Internet of Things, the number of mobile terminals and mobile data traffic are showing explosive growth. Research by my country's IMT-2020 (5G) Promotion Group shows that by 2020, the number of global mobile terminals (excluding IoT devices) will exceed 10 billion, and the number of global IoT devices will approach 7 billion. In February 2015, the Visual Network Indicators (VNI) report released by Cisco pointed out that by 2019, the global mobile data traffic will reach 292EB, an increase of nearly 10 times compared with 30EB in 2014. In order to cope with such a large ...
