Description
Technical Field
The invention relates to the technical field of 5G mobile communication, in particular to a 5G mobile communication control method.
Background
The method for building 5G ecology and promoting co-creation and co-utilization changes the mode method for realizing world and thinking problems by mobile communication, greatly promotes the development of society and economy, enables the spirit and life of people to be free to a greater degree, and becomes an indispensable important part in life of people. However, anything has two sides, the communication network is the same. Mobile communication is easy to be utilized by illegal criminals as a criminal tool while bringing openness, freedom and convenience to people. How to conveniently and efficiently regulate a communication network to prevent the communication network from being utilized by criminals becomes an important work of communication operators and national security departments.
The existing mobile communication control methods mainly comprise two types: (1) Manual closing of regional base stations or rough method such as pseudo base station is adopted; (2) By concatenating communication policing equipment between communication network element equipment of an operator.
The method (1) is original, and either the base station needs to be manually shut down, or a pseudo base station needs to be purchased and erected at a high cost. The method is rough and clumsy, the workload of operation and maintenance personnel is increased, the control cost is high, and once the base station is controlled, the communication of all terminals under the base station can be interrupted, and the communication among criminals is cut off, but the communication of normal users is also influenced. The method is not only unfavorable for the development of the work of the security department, but also causes a lot of telephone charge loss for operators due to network disconnection.
In the method (2), the communication control equipment is required to be connected in series to the communication link of the operator, the common practice is to connect the communication control equipment in series between the access network equipment and the core network equipment of the operator, and the minority is to connect the communication control equipment in series between the network elements in the core network of the operator. The complexity of the communication network architecture is increased no matter what serial connection mode is adopted, all communication data of the communication network architecture need to flow through the control equipment, so that the transmission delay of the data is increased, the processing performance of the data is reduced, the reliability and the effectiveness of the mobile communication network are influenced by the network equipment of a mobile communication carrier, the communication control equipment is also influenced, and the probability of failure of a communication link is increased as the number of the serial communication control equipment is increased. Once the communication control equipment has faults such as power failure, dead halt and the like, the influence surface is not narrower than that of the method (1), and if the communication control equipment is connected in series between an access network and a core network, the influence scope is all users under one or a plurality of base stations; if the communication control equipment is connected in series between the core network elements, the influence range is not only the base station level, but also the city-saving level user communication of the coverage area of the core network, and the visible influence range is wide. Faults such as power failure, dead halt and the like of the communication control equipment are also unfavorable for the development of the work of the security department, and huge telephone charge loss is brought to operators. In addition, the operator needs to worry about the problems that communication data is modified or lost due to possible misoperation of the communication control equipment, if the misoperation is relatively more, normal communication of the user is affected, and the public trust of the operator is seriously affected. In addition, when misoperation occurs, positioning and investigation are difficult, and the problems of cross-department and cross-manufacturer cooperation are solved, so that a plurality of unnecessary technical and business intercommunication barriers are easily added.
