Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] The inventor considers that the existing solution lacks an effective method for judging the random access load of the base station and EAB dynamic activation, and a reasonable configuration principle for corresponding parameters. According to the real-time characteristics of the business and t...

Abstract

The invention relates to the field of mobile communication, and discloses a dynamic access control method. The method comprises the following steps: a base station detects the usage of a random accesspreamble sequence; and according to the usage of the random access preamble, the base station dynamically adjusts random access control on terminals. Therefore, jamming is avoided, and the network access probability of the Internet of Things (IoT) terminals is improved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a dynamic access control method, base station and system. Background technique [0002] Operators urgently need to develop new business growth points to cope with the increasingly saturated situation of traditional human-to-human communications. It is predicted that by 2020, the number of IoT connections will exceed 5 billion. IoT has become a research hotspot in recent years. [0003] At present, the 3GPP standard is studying the use of the cellular network to carry the MTC service, but the characteristics of the service carried by the traditional cellular network and the MTC service are quite different. Therefore, it is necessary to enhance and optimize the corresponding functions of the cellular network to better meet the application requirements of the Internet of Things. The wireless network random access congestion caused by the simultaneous access of a large nu...
