Problems solved by technology

[0002] DMR (Digital Mobile Radio) terminal is a new type of digital handheld wireless terminal (commonly known as DMR digital walkie-talkie) that complies with the DMR technical specification of the European Telecommunications Standards Institute (ETSI). Powerful, of course, the baseband and radio frequency circuits are more complex than traditional analog walkie-talkies, using high-speed processors and large-capacity memory, the power consumption of the circuit is also greatly increased, which brings greater challenges to the design of improving battery support time

Embodiment

[0041] figure 2 Among them, the DMR protocol stipulates that a TDMA frame is divided into two burst time slots and the timing of the guard time. The structure of a 60ms TDMA frame includes 2 burst time slots, each occupying 30ms, and the middle of the two time slots is 2.5ms The guard slot, such as Figure 4 shown. The 5ms (48 bits) segment at the center of a 30ms burst in a time slot can transmit RC signaling information, such as Figure 5 shown.

[0042] by figure 1 As an example, assuming that MS1 is the local machine and MS2 is the peer end, the specific implementation steps include:

[0043] 1) The local MS1 obtains the RF signal field strength data RSSI;

[0044] 2) The local MS1 calculates the transmit power adjustment parameters of the peer MS2 according to the obtained field strength data RSSI;

[0045] 3) The local MS1 uses the RC reverse channel transmission power of the next burst time slot to adjust the parameters;

[0046] 4) The peer MS2 adjusts the tran...

Abstract

The invention provides a method for reducing the power consumption of a DMR (Digital Mobile Radio) terminal circuit. The method comprises the steps as follows: a transmitting power adjustment parameter of a receiving terminal is calculated and acquired by an emitting terminal through measuring and receiving the radio frequency signal field strength data; the power adjustment parameter is transmitted to the receiving terminal by the emitting terminal through an RC signaling channel; the transmitting power in the next time slot is adjusted by the receiving terminal according to the received power adjustment parameter. The method for reducing the power consumption of the DMR terminal circuit, provided by the invention does not rely on the sleep/wake up power saving mechanism of the system base station; and besides, the transmitting power can be adjusted dynamically by every terminal in a specific mode, so that the consumption of batteries is reduced to a greater extent, the average power consumption of the DMR terminal circuit is effectively reduced, the standby and duration of a DMR terminal battery is prolonged, and meanwhile, the electromagnetic environmental pollution of wireless communication equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for reducing power consumption of a DMR terminal circuit. Background technique [0002] DMR (Digital Mobile Radio) terminal is a new type of digital handheld wireless terminal (commonly known as DMR digital walkie-talkie) that conforms to the DMR technical specification of the European Telecommunications Standards Institute (ETSI). Powerful, of course, the baseband and radio frequency circuits are more complex than traditional analog walkie-talkies, using high-speed processors and large-capacity memory, the power consumption of the circuit is also greatly increased, which brings greater challenges to the design of improving battery support time. [0003] Handheld wireless terminals are generally powered by large-capacity rechargeable batteries, which have high requirements for battery capacity, standby time and working time. Restricted by factors such as ...
