Problems solved by technology

In the distributed trunking system, the terminal needs to scan channels to find an idle channel, and start a call on the idle channel, thus increasing the system access time; at the same time, the system does not perform any processing on the interference of the repeater, which also causes the system Access performance is degraded

Embodiment 2

[0075] When dealing with the uplink frequency interference of the repeater station, the present invention provides a second embodiment of an abnormality protection method of an extended trunking communication system, the process of which is as follows image 3 As shown, the method includes:

[0076] S301. The relay station monitors the uplink frequency interference in real time;

[0077] The specific detection methods can be:

[0078] The repeater is powered on and initialized, the system network connection is normal, and stays in the standby state; the repeater is in the transmitting or dormant state, and the receiving end detects that the carrier is valid; the repeater starts the carrier detection timer; waits for the carrier detection timer to expire;

[0079] While waiting for the carrier detection timer to expire, if the repeater detects that the carrier is invalid, it stops the carrier detection timer. The repeater considers that the uplink frequency point has no interf...

Embodiment 3

[0093] When dealing with the downlink frequency interference of the repeater station, the present invention provides a third embodiment of an abnormality protection method of an extended trunking communication system, and its flow is as follows Figure 4 As shown, the method includes:

[0094] S401. Real-time monitoring of downlink frequency interference;

[0095] The specific detection methods can be:

[0096] The repeater monitors the downlink frequency interference in real time through the detection equipment, and confirms the existence of the downlink frequency interference when receiving the notification of the downlink interference of the repeater sent by the detection equipment.

[0097] The detection device is in the receiving state of the downlink frequency of the repeater.

[0098] The detection device detects that the carrier is valid, but cannot decode a valid signal, or can decode a valid signal but its characteristics are determined to be signals outside the sy...

Embodiment 5

[0124] When dealing with the disconnection of the repeater station, the present invention provides a fourth embodiment of an abnormality protection method of an extended trunking communication system, the process of which is as follows Figure 6 As shown, the method includes:

[0125] S601. The repeater monitors its own abnormal disconnection status in real time;

[0126] S602. The repeater station detects that it is abnormally disconnected, and then confirms that the communication of the repeater station is abnormal;

[0127] S603. Determine whether the repeater is a free repeater; if yes, execute step S605; otherwise, execute step S604;

[0128] S604. When the own repeater is not a free repeater, update its own repeater state information, and send broadcast state information to the terminal, the broadcast state information carries the state information of the repeater with abnormal communication.

[0129] S604. When the relay station is a free relay station, update its own...

Abstract

The invention discloses an exception protection method for an extended trunked communication system and a relay station. The exception protection method comprises the following steps that: performing relay station communication exception monitoring in real time by the relay station in real time; when it is confirmed that the relay station is abnormal in communication, determining whether the relay station with abnormal communication is a free relay station or not; and updating and broadcasting the state information of the relay station with the communication exception when the relay station with the communication exception is a free relay station. According to the invention, corresponding exception handling and auxiliary notification mechanisms are carried out aiming at the communication exception condition of the relay station, so that the terminal can be effectively ensured to avoid the interfered channel in time and be quickly switched to the effective channel for communication, and the anti-interference capability and the calling reliability of the system are improved, and the call loss rate is reduced.

Description

technical field [0001] The name of the parent case of this application is "Anomaly Protection Method and Transit Station for Extended Trunked Communication System", application number "201510137158.8", and application date March 26, 2015. The invention relates to the field of trunking communication, in particular to a system abnormality (interference or disconnection) protection method. Background technique [0002] At present, the architecture of the wireless trunking communication system mainly includes two types: centralized and distributed. [0003] Such as figure 1 The centralized trunking system (Central trunking system) shown has a dedicated control channel and a center for mobile management. Usually, the control channel is in a long-term transmission state, and the terminals in the system stay on the control channel for monitoring. This cluster mode terminal needs to be successfully registered to the system to work normally. Walkie-talkie users usually stay on the...
