Embodiment
[0032] In this embodiment, a fast relay system for TDMA wireless ad hoc network services, such as figure 1 As shown, it includes 12 relay stations 2 and 4 mobile stations 1. Adjacent relay stations communicate with each other, and the mobile station only communicates with a specific relay station. The relay stations all use the DMR / PDT system of 2-slot TDMA Communication specifications, and can support TDMA duplex work, the mobile station only participates in the call, may not support TDMA duplex work.
[0033] A first fast relay signaling generator is provided in the mobile station for generating fast relay burst frames of the mobile station.
[0034] A second fast relay signaling generator, a fast relay signaling parser, and a memory are provided in the repeater, wherein the second fast relay signaling generator is used to generate a fast relay burst frame of the repeater, and the fast relay The relay signaling parser is used to analyze the fast relay burst frame of the mob...

The invention relates to a TDMA wireless ad hoc network service fast relay system and method. The system comprises a relay station, a mobile station, a first fast relay signaling generator, a second fast relay signaling generator and a fast relay signaling analyzer. The method comprises the following steps that: a TDMA time base and a superframe structure are confirmed; the mobile station generates a mobile station fast relay burst frame and transmits the mobile station fast relay burst frame; the relay station receives and partially analyzes the fast relay burst frame of the mobile station; and the relay station judges whether to forward or not according to the analysis result. The method has the advantages that the mobile station fast relay burst frame and the relay station fast relay burst frame are adopted to replace the original burst frame, so that the relay station can judge whether the burst frame needs to be forwarded or not under the condition that the whole burst frame is not completely received; the traditional scheme of firstly receiving and then analyzing is changed into the mode of firstly receiving the part and then receiving the rest part and analyzing at the same time, so that the time utilization rate is improved, the relay forwarding delay is shortened,.
Description
technical field [0001] The invention relates to the wireless field, in particular to a fast relay system and method for TDMA wireless ad hoc network services. Background technique [0002] DMR / PDT is currently a widely used digital professional wireless communication system standard. In some special occasions, such as the field, caves, tunnels and basements, there is often no base station signal or it is difficult to set up a base station. At this time, ad hoc network technology can only use mobile Under the condition of only one device, the communication distance is expanded through the networking between mobile stations to solve the problem of long-distance communication. [0003] During long-distance transmission, multiple ad hoc network jumps are required. Each jump will cause a certain delay in data transmission. If there are too many jumps, the delay index will be unacceptable. In DMR / PDT In the standard, the air wireless transmission standard is a TDMA transmission m...
