Description

Control method in communication, base station and terminal
Technical Field
The present invention relates to the technical field of communication security, and in particular, to a control method, a base station, and a terminal in communication.
Background
At present, the internet is gradually used as a new tool for implementing terrorist crime, popularizing ethnic division and religious extreme ideas by lawless persons while becoming a new engine for global economic development. For example, according to incomplete statistics, horror audio and video 282 parts are released from 2010 to 2014 by terrorist organization 'east yi fortune' identified by the united nations and security association, the release quantity is increased year by year, and even explosive growth occurs in 2013; in the same year, the number of terrorist events in China is also increased. The draft of network security law proposes that temporary measures such as limitation on network communication in part of regions can be taken by national courts or governments of provincial, autonomous and direct municipalities, which are approved by national courts, because of the need of maintaining national security and social public order and handling major sudden social security events. In addition, in many cases in real life, communication control of terminals in a certain key area, for example, an important meeting, an important examination, and the like, is also required. In addition to social events, communication control when natural disasters occur is also one of alternative emergency management means. During the hurricane of the United states Katerlina, the United states Federal communication Commission limits public communication in partial areas while increasing the emergency repair force of communication infrastructure and recovering communication, so as to ensure smooth communication of the disaster relief and security departments such as police, fire fighting and the like. In the "internet +" era, networks have become indispensable elements for social economy and public life, and therefore, a fine and effective technical means must be adopted when network communication control is implemented to realize accurate communication control at a specific time and in a specific area.
At present, a traditional network communication management and control mode is realized by adopting extensive means such as closing a regional base station, communication in a coverage area of the base station can be completely interrupted in the way, the coverage area of the base station is relatively wide (generally 1-2 kilometers in a city), the management and control granularity is not detailed enough, the rapid development of work of relevant departments for dealing with emergency emergencies is not facilitated, and meanwhile, operators also need to bear huge telephone charge loss caused by network disconnection. In addition, communication is interrupted by additionally installing a signal shielding system in some scenes, but due to continuous construction and upgrading of an operator network, physical equipment cannot be updated in time, so that management and control of some communication systems are lost, a large number of blind spots and dead corners exist, many areas can still communicate, and the risk of incomplete management and control exists. Related departments such as military industry and the like have systems for performing communication control and monitoring of key areas and communication monitoring and tracking of key personnel by using a pseudo base station technology. However, existing pseudo base stations are all for Global System for mobile communications (GSM) networks, and when a terminal receives a location update request, the pseudo base station is accessed, because the service type of the pseudo base station is limited, a terminal signal is shielded, and the terminal may be re-accessed to the original network through cell reselection, so that the terminal is not disconnected completely; moreover, The pseudo base station in The GSM network is not suitable for a Code Division Multiple Access (CDMA) handset, a Third Generation mobile communication technology (3G), and a Fourth Generation mobile communication technology (4G), because, after The audio and video call technology (VoLTE, Voice over LTE) in The 4G network is used in commerce, The audio and video call does not go through The conventional 2G channel, and this control means will fail.
