[0050] In the first embodiment of the present invention, a method for controlling an eMTC terminal to connect to a base station, such as figure 1 shown, including the following specific steps:

[0051] In step S101, when the eMTC terminal is about to randomly access a base station of the eMTC system, the eMTC terminal randomly generates a first connection duration.

[0052] Specifically, step S101 includes:

[0053] When the eMTC terminal is in the IDLE (idle) state and is ready to actively send random access to the base station of the eMTC system, the eMTC terminal randomly generates the first connection duration;

[0054] Or, when the eMTC terminal is in an IDLE (idle) state and receives the paging information sent by the base station of the eMTC system, the eMTC terminal randomly generates the first connection duration.

[0055] For example: when the eMTC terminal is in the IDLE (idle) state and is ready to actively send random access to the base station of the eMTC syste...

[0059] In the second embodiment of the present invention, a control method for connecting an eMTC terminal to a base station, such as figure 2 As shown, the method in this embodiment includes the following specific steps:

[0060] Step S201, according to the type of eMTC terminal, set the longest connection duration.

[0061] For example, according to the type of eMTC terminal, set the longest connection duration t x = 20ms.

[0062] Since the services carried by different types of eMTC terminals have different requirements for random access delay, different maximum connection durations are set for different types of eMTC terminals according to different types of eMTC terminals.

[0063] Step S202, when the eMTC terminal prepares to randomly access the base station of the eMTC system, the eMTC terminal randomly generates a first connection duration. Wherein, the first connection duration is less than the longest connection duration.

[0064] Specifically, step S202 includ...

[0071] In the third embodiment of the present invention, a method for controlling an eMTC terminal to connect to a base station, such as image 3 As shown, the method in this embodiment includes the following specific steps:

[0072] Step S301, according to the type of eMTC terminal, set the longest connection duration.

[0073] For example: according to the type of eMTC terminal, set the longest connection duration t x = 20ms.

[0074] Since the services carried by different types of eMTC terminals have different requirements for random access delay, different maximum connection durations are set for different types of eMTC terminals according to different types of eMTC terminals.

[0075] Step S302, when the eMTC terminal prepares to randomly access the base station of the eMTC system, the eMTC terminal randomly generates a first connection duration shorter than the longest connection duration.

[0076] Specifically, step S302 includes:

[0077] When the eMTC terminal is...

Abstract

The invention provides a control method and device for connecting an eMTC terminal to a base station. The method comprises the steps of: when the base station of an eMTC system is prepared to be accessed randomly, randomly generating the first connection time; and, after the first connection time is delayed, sending a random access request to the base station of the eMTC system. By means of the method, the signalling storm due to the fact that a large number of eMTC terminals simultaneously initiate random access requests can be avoided; therefore, the eMTC network congestion probability is reduced; the success rate of randomly accessing the eMTC terminal to the base station is effectively increased; and the control method and device provided by the invention have relatively low complexity, and have better optimization and improvement effects on congestion control of the eMTC system.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a control method and device for eMTC terminals connecting to base stations.
