Problems solved by technology

[0005] The S1 interface is the interface between the EPC and the eNodeB. In the prior art, when the eNodeB detects that the S1 interface fails, the eNodeB will forcibly release all users in the cell, so the impact of the failure is huge.

Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0026] Such as figure 2 As shown, the embodiment of the present invention provides a method for weakening a fault of a digital trunking system, the method comprising:

[0027] S10, if the eNodeB detects that its own S1 interface fails, it sends a system broadcast message to all cells under the eNodeB to prohibit the cell from accessing new users, maintains the connection status of all online users under the eNodeB, and instructs the wireless The dispatcher dispatches the online users under the eNodeB;

[0028] S20, if the eNodeB detects that its own S1 interface has recove...

Abstract

The invention discloses a fault weakening method of a trunking system, which is applied to a broadband digital trunking system based on long-term evolution LTE. When an S1 interface fails, an eNodeB sends a system broadcast message to all cells under the eNodeB to prohibit cell access For new users, maintain the connection status of all online users under the eNodeB, and instruct the wireless dispatcher to schedule the online users under the eNodeB. After the S1 interface fault is restored, the eNodeB sends a system broadcast message to all cells under the eNodeB to Lifting the prohibition on accessing new users in the cell can weaken the impact of SI interface failure on trunking communication, and maintain the continuous scheduling management of trunking communication within the scope of the base station. The invention also discloses the corresponding fault weakening device of the cluster system.

Description

technical field [0001] The present invention relates to the technical field of trunking communication, in particular to a method and device for weakening faults of a broadband digital trunking system based on long-term evolution LTE. Background technique [0002] The trunking communication system is a dedicated wireless communication system for specific industry applications developed to meet the command and dispatch needs of industry users. In the system, a large number of wireless users share a small number of wireless channels, and the command and dispatch is the main application. It is a multi-purpose, high-efficiency wireless communication system. The trunking communication system has a wide range of application markets in the fields of government departments, public safety, emergency communications, electric power, civil aviation, petrochemical and military. [0003] With the rapid development of mobile Internet and the large-scale construction of global wireless citi...
