Embodiment Construction

[0033] The present invention relates to a method for dynamically guaranteeing key communication in the field of public security. In order to realize the method, a system for ensuring key communication is built. The system architecture relation diagram is shown in figure 1 .

[0034] The overall structure of the key communication support system for dynamic coordination is as follows:

[0035] For the notification of key user attributes triggered by the dispatcher, it is necessary for the dispatcher, core network and base station to jointly complete key communication guarantees. For key user communication guarantees actively notified by the UE, the cooperation of the UE, base station, core network, and dispatcher is required. Such as figure 1 , the UE can change its key attributes according to its own site conditions, report to the base station and notify the dispatcher on the network side to pay attention, and the dispatcher can also modify the key attributes of the correspon...

Abstract

The invention relates to a method used for dynamically guaranteeing key communication and specific to the public security field and belongs to the technical field of public security communication guarantee. The method comprises the following steps: (1) a user or dispatching desk triggers a key attribute updating command of a user according to conditions of a scene where the user is located and transmits key attribute information of the user to a base station; (2) when the base station receives key attribute updating information of the user, namely the user is a key user, key attribute information of the user is reported to informed to a network side, and the network side triggers caution information and informs a dispatching commander to pay close attention to field information of user equipment (UE); and (3) when the base station performs traffic scheduling processing, by virtue of a key guarantee process, the effect that an uplink video of the key user is transmitted to the network side at high quality is guaranteed. By virtue of the method provided by the invention, the user or dispatching desk can dynamically change key attribute of the user, and the base station can complete communication quality guarantee of the key user according to the key attribute of the user, thereby guaranteeing timely and effective task execution in a complex scene and guaranteeing security of themass and personnel on duty.

Description

technical field [0001] The invention relates to a method for dynamically guaranteeing critical communication aimed at the field of public security, and belongs to the technical field of public security communication guarantee. Background technique [0002] For special scenarios in the field of public security, the dispatch command center needs to monitor the video or other real-time data services of key users at the mission site in real time, or the wireless remote executor needs to send the on-site data information in real time when he confirms that he is in an emergency. Feedback to the dispatching center, and the dispatching command center will make relevant coordination control and issue orders in a timely manner according to the information sent back from the scene in real time. For key users, who may be in law enforcement and generally mobile, the channel quality is likely to be poor, so how to ensure the reliability of on-site data transmission so that dispatchers can...
