Problems solved by technology

[0004] When the camera is connected wirelessly, due to the limited bandwidth of wireless resources, the video resolution when the video surveillance is established often only meets the definition on the computer. The operation of the screen is the signaling interaction between the video platform and the camera. The wireless resource scheduling of the base station cannot obtain the information on the large screen. As a result, the bandwidth of the large screen cannot be reliably guaranteed, and the clarity of the video on the large screen cannot be guaranteed.

[0028] This embodiment provides a technical solution of a bandwidth allocation method. In this technical solution, the bandwidth allocation method is performed by a base station in a mobile communication system. Typically, the base station may be an evolved node B (Evolved node B, eNB) in an LTE or LTE-A system.

[0029] see figure 1 , the bandwidth allocation method includes:

[0030] S11. The base station receives a high-definition video request uploaded by a user through a video monitoring platform.

[0031] The video monitoring platform is set up on the network and is dedicated to monitoring video transmission network equipment. There is an available network connection between such a network device and the base station, and the high-definition video request can be transmitted to the base station through the network connection.

[0032] The high-definition video request is a request message for requesting high-definition video transmission uploaded by the user to the ba...

[0040] This embodiment further provides another technical solution of the bandwidth allocation method based on the foregoing embodiments of the present invention. In this technical solution, the base station dynamically adjusts the bandwidth allocation according to the real-time bandwidth usage of all service users, including: when the idle bandwidth cannot meet the high-definition video request, the base station seizes the bandwidth of the low-priority user to serve the user Allocate bandwidth that satisfies the high-definition video request; when preempting the bandwidth of low-priority users cannot meet the transmission requirements of high-definition video, the base station restores the occupied bandwidth of other high-definition video requests except the current high-definition video request to The minimum reserved bandwidth; and when the bandwidth of low-priority users is preempted, and the occupied bandwidth of other high-definition video requests other than the current ...

[0056] Based on the foregoing embodiments of the present invention, this embodiment further provides a technical solution for bandwidth adjustment in the bandwidth allocation method. In this technical solution, when the idle bandwidth cannot satisfy the high-definition video request, the base station preempts the bandwidth of the low-priority user, so as to allocate the bandwidth that meets the high-definition video request for the video monitoring platform, including: the base station obtaining the The bandwidth gap requested by the high-definition video; according to the bandwidth gap, the base station preempts the bandwidth of low-priority users in order of priority from low to high until the bandwidth gap is satisfied.

[0057] see image 3 , when the idle bandwidth cannot satisfy the high-definition video request, the base station preempts the bandwidth of the low-priority user, so as to allocate the bandwidth satisfying the high-definition video request for the video sur...

Abstract

The embodiment of the invention discloses a bandwidth allocation method and a base station. The method comprises the steps that: the base station receives a high-definition video request uploaded by a user; the base station set the user as a high priority user; the base station dynamically adjusts bandwidth allocation according to the real-time bandwidth use of all service users, and allocates a bandwidth which satisfies the high-definition video request for the user. According to the bandwidth allocation method and the base station provided by the embodiment of the invention, the video definition in transmitting a high-definition video in a mobile communication scene is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular, to a bandwidth allocation method and a base station. Background technique [0002] The cluster communication system is a command and dispatch system, which is widely used in private networks, especially video dispatch. As a command and dispatch center, it is necessary not only to be able to hear the on-site voice, but also to be able to see the video that occurs on-site, so as to be more efficient, Make decisions more accurately, so video scheduling is widely used in cluster private networks. [0003] The application of video dispatching in the cluster private network includes: video single call, video group call, video broadcast, video surveillance, video forwarding, video return, etc. In the public security and traffic police industry, more video surveillance is used, such as in highway Cameras are installed in important areas, and the ...
