Problems solved by technology

Compared with the voice service, the high bit rate of the video service will occupy more resources. Lowering the MCS of the multicast bearer will lead to a sharp decrease in the capacity of the base station. For those users with good signal quality, it will lead to waste

Abstract

The embodiment of the present invention proposes a video group call method and device in broadband trunking communication. The method includes: receiving a video group call request including the group number of the video group; establishing a video group call for members in the video group based on the video group call request, and pushing the video to the video group based on the multicast downlink bearer When it is determined that the user terminal (UE) is a member of the video group and the signal quality of the UE does not meet the predetermined standard, a video single call is established for the UE, and the video is pushed based on the unicast downlink bearer to the UE. The embodiment of the present invention provides video single call and analog video group call for users with poor signal quality, does not affect the multicast bearer of video group call, has limited impact on the capacity of the base station, and at the same time ensures service quality, increases transmission reliability, and reduces delay , to improve coverage.

Description

technical field [0001] The invention belongs to the technical field of Broadband Trunking Communication (B-TrunC), and in particular relates to a video group call method and device in broadband trunking communication. Background technique [0002] With the rise of smart terminals and mobile Internet, wireless data services have shown explosive growth. With the rapid development of industries such as global public security, government affairs, transportation, and energy, industry users have rapidly growing demands for broadband wireless data services and multimedia trunking scheduling on the basis of traditional voice trunking, and the demand is extremely urgent. As the global 4G standard, LTE technology has the advantages of high speed, high spectral efficiency, low delay, etc., and has strong industrial strength. It has become the common choice of global wireless private network broadband technology. The evolution of broadband trunking technology based on LTE technology ha...
