Problems solved by technology

If the transmission power of the MPT1327 mobile handheld station adopts high power, then when the handheld station is close to the base station, the power must be excessive, and the current consumed by the high power is very large, which is undoubtedly a waste of electric energy and shortens the battery life; and the distance from the base station is relatively large. Near strong signals will suppress weak signals far away from the base station, causing near-far effect
The traditional solution is that the user manually adjusts the transmit power of the MPT1327 mobile handheld station, which will cause the signal to suddenly weaken or increase suddenly and cause additional interference to other users, and manual adjustment also brings inconvenience to the user

Abstract

The invention provides an automatic power adjusting method of a microprogramming technique 1327 (MPT1327) mobile hand-held station with electricity saving, longer standby time of terminal and excellent performance. The transmitting power of the MPT1327 mobile hand-held station is automatically adjusted according to a received signal strength indication (RSSI) value transmitted by a base station. Two RSSI threshold values are set for the MPT1327 mobile hand-held station, the transmitting power values corresponding to the two threshold values are respectively calculated, modeling is carried out according to the threshold values and the corresponding power values and by referencing an electric ware space transmission theory so as to establish a mathematical model. The MPT1327 mobile hand-held station detects the strength of signals transmitted by a base station at any time, and the transmitting power of the hand-held station is dynamically calculated according to a model function, thereby the automatic adjustment of the transmission power of the MPT1327 mobile hand-held station is realized. The invention can reduce electricity consumption, prolong the standby time of the terminal, has more excellent performance, improve the user experience of users and fully use the inherent technological advantages of the MPT1327 mobile hand-held station.

Description

(1) Technical field [0001] The present invention relates to communication technology, specifically a method for automatic power adjustment of MPT1327 mobile handheld station. (2) Background technology [0002] In traditional MPT1327 mobile handheld station applications, MPT1327 mobile handheld stations use fixed high and low transmission power levels, which are manually adjusted by the user according to the distance from the base station. Due to the random mobility of the MPT1327 mobile handheld station, the distance between the MPT1327 mobile handheld station and the base station also changes randomly. If the transmission power of the MPT1327 mobile handheld station is the same, the strength of the signal arriving at the base station is different. Weak, the nonlinearity of the MPT1327 cluster mobile communication system will be further aggravated, and the stronger will be stronger, that is, the near-far effect. Because the MPT1327 mobile handheld stations are randomly dist...
