Embodiment Construction

[0021] Specific embodiments are described in detail below, but not as a limitation to the present invention.

[0022] combine figure 2 As shown, the specific process of the traditional group reverse power optimization method in the digital trunking system of the present invention is as follows:

[0023] First, the base station subsystem configures the transmit power of the reverse signaling of each mobile terminal in the non-talk state, mainly to reduce the reverse signaling transmit power of each mobile terminal in the non-talk state, and sends the configured transmit power to Each mobile terminal; the specific way to reduce the transmission power can be configured on the side of the base station subsystem. By reducing the transmit power of the reverse signaling of each mobile terminal, the near-far effect can be overcome and the interference to other users in the shared frequency band can be reduced.

[0024] For the base station subsystem configuration in the above-menti...

Abstract

The invention discloses an optimizing method for traditional group reverse power in a digital trunking system, which comprises: emission power of reverse signaling when basic station sub-system configuration mobile terminals are in the state of non-speaking, retransmitting times of speaking retransmitting application and incremental change of every retransmitting power, and sending the configured retransmitting power to each mobile terminal; when mobile terminals apply to the basic station sub-system for speaking right at the configured sending power, if the application succeeds, the basic station sub-system issues success signaling to mobile terminals; otherwise, mobile terminals make speaking right retransmitting application according to retransmitting times by taking the current sending power plus incremental change of retransmitting power increased by times at retransmitting times as sending power, if wherein certain application succeeds, the basic station sub-system issues success signaling to the mobile terminal, if no application succeeds in retransmitting times, the speaking right application finishes. The optimizing method solves the problem of communication jamming among traditional group users in the digital trunking system.

Description

technical field [0001] The invention relates to the field of digital trunking systems, more specifically, to a traditional group reverse power optimization method in the digital trunking system. Background technique [0002] With the rapid development of domestic cellular mobile communication systems, domestic communication companies have successively developed a variety of wireless communication products based on second-generation technology to meet the needs of mobile communication. In the process of continuously meeting the needs of market and technological development, domestic mobile The communication industry has gradually matured, and the research and development capabilities have also been greatly improved, basically possessing the ability to provide digital trunking mobile communication systems with independent intellectual property rights. [0003] ZTE has been committed to the research of digital trunking communication, and proposed a new set of digital trunking c...
