Problems solved by technology

[0007] The present invention solves the problem in the prior art that when a transmission failure causes a disconnection between the base station and the base station controller, users under the base station cannot communicate, so as to ensure that the trunking function can still be completed under the condition of a transmission failure, that is, in After the base station loses contact with the base station controller, functions such as group calls can still be realized

Embodiment Construction

[0020] In order to facilitate the understanding of the present invention, first describe the logical functions of the base station, such as figure 1 As shown, according to logical function division, the base station can be divided into a main control unit (MCU), a signaling processing unit (SCP), and a voice digital signal processing unit (DSP). Wherein, the MCU is used to realize the transmission interface between the whole base station and the base station controller, and realize the main control function of the base station. The SCP is used to complete signaling processing. DSP is used to finish speech processing.

[0021] The configuration of the faulty base station is uncertain, but its minimum configuration is one carrier frequency per cell. Therefore, in the present invention, the base station failure of one carrier frequency in one cell is considered. When a cell has multiple carrier frequencies, only one carrier frequency can be started to work. There are 8 channel...

Abstract

The method for solving the problem not capable of making phone call after the base station disconnects to the base station controller and comprises: the control unit of base station detects the transmission link of base station; when deciding a transmission interruption happens, the working mode of base station is set as a fail-soft mode; the signaling processing unit configures the frequency carrier, it includes system information, channel configuration and notice message description; then, the signaling processing unit fills out the received system information into the system message field, and transmits the notice message description on NCH channel; after receiving the notice message description, the mobile phone stays in relevant time slot according to a failure-soft channel ID configured for it in order to initiate or receive the PTT calling.

Description

technical field [0001] The invention relates to digital cluster communication technology, more specifically, to a method for implementing fault weakening in cluster network communication. Background technique [0002] The digital trunking communication network is a new type of mobile communication system emerging at the end of the 20th century. In addition to the personal mobile communication services provided by the public mobile communication network (GSM, CDMA), it can also realize arbitrary communication between individuals and groups. Among them, GT800 is a new technology of professional digital trunking based on time division multiple access. Combining cellular technology, it can provide professional users with high-performance, large-capacity trunking services and functions through creative optimization and integration of TDMA and TD-SCDMA technologies. Its system is stable and sustainable, and has the following characteristics : [0003] (1) Fast connection perform...
