Description

A kind of method and device that reduces the digital handset power consumption

Technical field

The present invention relates to digital handset, relate in particular to a kind of method and device that reduces the digital handset power consumption.

Background technology

Intercom is because the instantaneity of its communication and free principle are widely used in various fields.Along with deepening continuously of intercom mould revolution process, digital handset is more and more used, and its speech quality and channel utilization are greatly improved.Digital handset obtains the attention of many manufacturers as the communication mode in specific communication field, has proposed plurality of communication schemes, comprises standards such as DPMR, DMR, iDEN, TETRA.As the maximum intercom supplier in the whole world, China continues to increase input in the digital handset field, has obtained significant progress.

Different with public communication network such as GSM, in most of the cases intercom communication does not have the base station to transmit, and directly realizes real time communication end to end.Because its asynchronous transfer mode of eating dishes without rice or wine, how guaranteeing to reduce as much as possible under the reliable situation of data power consumption and be each manufacturer all needs the problem that solves.

The simulation intercom does not have air protocol, has or not the uninterrupted monitor channel signal strength signal intensity of signal demand in order to monitor, and promptly begins after transmitting to receive when having detected.Because its monitoring circuit is in running order all the time, constantly consumed power so the complete machine stand-by time is short, can only be worked about 8 hours.

Digital handset has defined complicated air interface protocol, and intercom carries out protocal analysis and comes control data transmitting-receiving by the parsing data of eating dishes without rice or wine.The power problems of digital handset will directly influence its use, and digital handset still is in the stage of applying at present, and how power saving does not still have solution at present at digital handset, and this also is that each manufacturer needs the constantly direction of effort.

Embodiment

Describe embodiment of the present invention in detail below in conjunction with accompanying drawing.

Referring to Fig. 1, the figure shows a kind of method that reduces the digital handset power consumption of the embodiment of the invention, comprise step:

Step S101: digital handset detects channel signal strength according to default channel strength sense cycle;

Step S102: when described channel signal strength surpasses a threshold value, then enter normal operating conditions, otherwise, enter sleep state.

Wherein, digital handset is closed all closable circuit when entering sleep state, reduce to the power consumption of entire circuit minimum.

Wherein, described threshold value is the intensity of the effective call signal of digital handset generally speaking, and concrete value can rule of thumb be worth setting, and the present invention does not limit at this.

The embodiment of the invention is dexterously according to the digital handset agreement, under holding state, adopt intermittent operation mode, periodicity monitor channel signal, if do not hear the channel signal that meets certain intensity, then enter sleep state, thereby save the electric power of digital handset well, prolong its service time.

For further conservation of power, preferably, described digital handset can also parse called number from described detected channel signal after entering normal operating conditions, if described called number is not a loCal number, then enter resting state.Thereby by filtering unnecessary calling (calling of non-this machine of calling), further conservation of power.

Cause erroneous judgement disconnected in order to prevent to disturb, preferably, described digital handset can also be when N continuous time detects channel signal strength and surpasses described threshold value, thinks that just described channel signal strength above described threshold value, enters normal operating conditions then; N is a positive integer.Thereby also further conservation of power.

Wherein, described channel signal can comprise preposition pilot signal and valid data signal, and described preposition pilot signal is used for the recipient to be measured with synchronously, and it is positioned at before the described valid data signal.Adopt and above-mentionedly time detect channel signal strength in N continuous and surpass described threshold value as the preferable criterion that enters normal operating conditions, then corresponding, the duration of the product of described default channel strength sense cycle and described times N less than described preposition pilot signal need be set.To guarantee in preposition pilot signal duration, finishing the measurement synchronization process.

Be that example is described further with an application example shown in Figure 2 below.Digital handset MS (A) is a transmit leg, and emission two frames guide frame E2 and E1 earlier before valid data frame H, so that the recipient measures with synchronously.Digital handset MS (B) and MS (C) are the recipient, and both all detect channel signal as the criterion that enters normal operating conditions with continuous 3 times.MS (B) and MS (C) have represented two kinds of extreme sequential situations.The 1st sense cycle of MS (B) do not detect and transmits, and the 2nd, 3,4 sense cycle is continuous to be detected for 3 times and to begin to receive after transmitting, and this moment, time of reception was the shortest in advance, and consumes power is minimum.The 1st sense cycle of MS (C) just detects signal, begins to receive after the 2nd, 3 sense cycle is consecutively detected signal, and this moment, time of reception was the longest in advance, the consumes power maximum.All the other situations are between both of these case, and consumes power is moderate.

In order to realize said method, the embodiment of the invention also provides a kind of device that reduces the digital handset power consumption, as shown in Figure 3, comprising:

Detection module is used for detecting channel signal strength according to default channel strength sense cycle.

Processing module is used for obtaining testing result from described detection module, when described channel signal strength surpasses a threshold value, then enters normal operating conditions, otherwise, enter sleep state.

For further conservation of power, preferably, described processing module also after entering normal operating conditions, parses called number from described detected channel signal, if described called number is not a loCal number, then enter resting state.Thereby by filtering unnecessary calling (calling of non-this machine of calling), further conservation of power.

Cause erroneous judgement disconnected in order to prevent to disturb, preferably, described channel signal strength surpasses a threshold value and can be meant, the inferior channel signal strength that detects of described processing module N continuous surpasses described threshold value; N is a positive integer.That is, it is channel signal strength when surpassing described threshold value that N continuous time receives testing result, just enters normal operating conditions.

Wherein, described channel signal can comprise preposition pilot signal and valid data signal, and described preposition pilot signal is used for the recipient to be measured with synchronously, and it is positioned at before the described valid data signal.Surpass described threshold value as the preferable criterion that enters normal operating conditions if employing is above-mentioned in the inferior channel signal strength that detects of N continuous, then corresponding, the duration of the product of described default channel strength sense cycle and described times N less than described preposition pilot signal need be set.To guarantee in preposition pilot signal duration, finishing the measurement synchronization process.

Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those skilled in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
