Embodiment
Basic thought of the present invention is: a kind of mechanism of the system equipment public channel power being adjusted according to the actual demand of subscriber equipment is provided, subscriber equipment need guarantee the wireless coverage quality, judge whether the current wireless covering quality satisfies the demands, if satisfy the demands, then continue normal communication process or idle process; If do not satisfy, then to system equipment emission communication request signal.System equipment is controlled public channel transmissive power according to the communication request signal of subscriber equipment.
Like this, when the wireless coverage quality can not satisfy the demand of subscriber equipment, system equipment can improve public channel transmissive power or directly adopt the maximum public channel transmissive power Pmax of configuration; And when subscriber equipment did not need to communicate by letter, system equipment can reduce public channel transmissive power even public channel transmissive power is reduced to zero.Thereby reach the energy resource consumption of saving entire wireless communication system, reduce the purpose of radio-frequency pollution.
Based on above-mentioned thought, the present invention specifically adopts following technical scheme:
If subscriber equipment is judged the current wireless covering quality and is not satisfied the demands, then to system equipment emission communication request signal;
The access entity of system equipment is controlled public channel transmissive power according to the described communication request signal that receives.
Wherein, when the access entity of system equipment receives the communication request signal of subscriber equipment, public channel transmissive power is carried out following control: if current public channel transmissive power is less than maximum public channel transmissive power Pmax, then, perhaps directly adopt maximum public channel transmissive power Pmax with step-length of current public channel transmissive power lifting.
Further, when subscriber equipment guarantees the wireless coverage quality at needs, measure the current wireless covering quality and judge whether to satisfy the demands, if do not satisfy, then to system equipment emission communication request signal;
Wherein, subscriber equipment need guarantee the wireless coverage quality in following situation: subscriber equipment need be initiated communication, or subscriber equipment need carry out the sub-district switching judging under communications status, or subscriber equipment need carry out the cell change judgement under idle condition, etc.
Further, subscriber equipment is after system equipment emission communication request signal, once more the wireless coverage quality is detected after crossing the certain hour interval, if still do not satisfy, then launch communication request signal to system equipment, until the emission maximum energy that reaches subscriber equipment with bigger emitted energy; If subscriber equipment is launched communication request signal with the emission maximum energy to system equipment, and after crossing the certain hour interval, the wireless coverage quality does not still satisfy the demands, and then is transformed into other frequency frequency ranges or other wireless communication systems.
Wherein, judge that the index whether the wireless coverage quality satisfies the demands can comprise: receive the signal strength signal intensity of down public guide frequency channel, the signal to noise ratio of down public guide frequency channel etc.Signal strength signal intensity is strong more, and signal to noise ratio is high more, and then the wireless coverage quality is good more.
Further, initiate communication from the access entity of system equipment if desired, then insert entity and adopt maximum public channel transmissive power Pmax emission common signal channel, perhaps, with rising step-length of current public channel transmissive power lifting.
Further, insert entity timer is set, in the time-count cycle of this timer, initiate communication if insert entity, perhaps detect the communication request signal of subscriber equipment, then after current public channel transmissive power was controlled, timer carried out timing again;
If when arriving the time-count cycle of this timer, insert entity and do not initiate communication, also do not detect the communication request signal of subscriber equipment, after then current public channel transmissive power being reduced a decline step-length or being reduced to zero, timer carries out timing again.
Enforcement to technical solution of the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Fig. 2 is the common signal channel control flow chart that the system equipment of the embodiment of the invention inserts entity.Sub-district in wireless base station or the base station, sector etc. can be as inserting entity.As shown in Figure 2, this flow process is described below:
Step 201 after the initialization of access entity, promptly starts timer;
When inserting the entity initialization, the public channel transmissive power Pmax that configuration is maximum.This Pmax promptly is equivalent to the common signal channel fixed transmission power in the conventional art.
Step 202 inserts entity and constantly detects communication request signal, if detect communication request signal, perhaps, insert entity and will initiate communication, such as paging etc., then carry out next step 203, otherwise, after timer arrives T1 time-count cycle, execution in step 205;
Step 203 inserts the power P max emission common signal channel of entity with configuration, perhaps with a rising step-length of current public channel transmissive power lifting UpDeltaP (if the power after the lifting greater than Pmax, is then used Pmax), and carry out next step 204;
Wherein, if insert entity detection to communication request signal, then thinking has the better network coverage of user's needs to communicate, can the lifting public channel transmissive power, and the also direct maximum power Pmax of recovery configuring; And to initiate communication if insert entity, the then preferred directly maximum power Pmax of recovery configuring.
Step 204 with the timer zero clearing, is returned step 201 and is restarted timing;
Step 205, timer arrives T1 time-count cycle, does not detect communication request signal if insert entity in the T1 time period this time-count cycle, does not also newly initiate communication, then carries out next step 206;
Step 206, the timer timing reaches T1 time-count cycle, then represent not detect communication request signal in the nearest time period T1, do not insert the new communication of initiating of entity yet, can reduce public channel transmissive power this moment, for example current public channel transmissive power is reduced a decline step-length DeltaP (if current transmit power is less, as less than DeltaP, then can directly transmitting power be reduced to 0), then, forward step 204 to the timer zero clearing, timer restarts timing.
Process chart when Fig. 3 need guarantee the wireless coverage quality for subscriber equipment.As shown in Figure 3, this flow process is described below:
Step 301, subscriber equipment need guarantee the wireless coverage quality;
Wherein, subscriber equipment need guarantee the wireless coverage quality in following situation: subscriber equipment needs newly to initiate communication, or subscriber equipment needs to carry out the sub-district switching judging under communications status, or subscriber equipment needs to carry out cell change and judge under idle condition, etc.
Particularly, when subscriber equipment is initiated new traffic at needs, need to measure the current wireless covering quality and judge whether to satisfy the demands; And be in communication or idle condition following time, can periodically measure the current wireless covering quality and judge whether to satisfy the demands.
Step 302, subscriber equipment is measured the current wireless covering quality and is judged whether to satisfy the demands, if satisfy, then execution in step 303, otherwise the current wireless covering quality is relatively poor, can't satisfy the demand of subscriber equipment, execution in step 304;
Step 303, wireless coverage is good, can operate as normal;
Step 304, subscriber equipment is launched communication request signal to system equipment, carries out next step 305 then;
Step 305, subscriber equipment are crossed and are measured the current wireless covering quality once more after the certain hour interval T 2 and judge whether to satisfy the demands, if satisfy, then execution in step 303; If still can't satisfy the demand of subscriber equipment, then execution in step 306;
Step 306, subscriber equipment judge whether can also communication request signal emitted energy, if then execution in step 307, otherwise, execution in step 308;
Step 307, subscriber equipment is launched communication request signal with bigger emitted energy to system equipment, returns step 305 then;
Step 308 if subscriber equipment can not obtain the wireless coverage quality that needs with very big energy, thinks that then this communication request attempts failure, and subscriber equipment need consider to be transformed into other frequency frequency range even other wireless systems go communication.
In concrete example of the present invention, the form of described communication request signal can adopt one section autocorrelation performance broad sense layering preferably Gray code (Generalised Hierarchical Golay Sequence) sequence, and it is defined as:
a＝<1，1，1，1，1，1，-1，-1，1，-1，1，-1，1，-1，-1，1>，
Cgolay＝(1+j)×<a，a，a，-a，-a，a，-a，-a，a，a，a，-a，a，-a，a，a>；
Wherein, j is the imaginary part unit of plural number.
As seen, Cgolay is a sequence that comprises 256 plural numbers.Communication request signal can be that the one or many of sequence of complex numbers Cgolay repeats.Such as, the length of communication request signal can be the sequence of 256 plural numbers, also can be sequence of 512 plural numbers etc.But the form of the communication request signal among the present invention is not limited to above-mentioned example.
From the handling process of said system equipment and subscriber equipment as can be seen, if system equipment inserts communication request signal and Pmax of no use emission common signal channel that entity receives subscriber equipment, then should insert entity will as early as possible (such as 5ms) directly recover to launch common signal channel or a rising step-length of lifting power UpdeltaP (if the power after the lifting is greater than Pmax with Pmax, then use Pmax), if and both do not received communication request signal in the T1 a time-count cycle, do not initiate new traffic yet, then will reduce public channel transmissive power.
And subscriber equipment only monitors whether the communication request (as paging request) of system equipment to this subscriber equipment is arranged when self not needing to communicate by letter.When needs were communicated by letter, subscriber equipment was at first measured the current wireless covering quality, in addition, when subscriber equipment is in communications status, also need periodic measurement current wireless covering quality, satisfy communication requirement, then proceed normal communication if judge the current wireless covering quality; Do not satisfy the demands if judge the current wireless covering quality, then launch the wireless signal of communication request to system equipment.After the emission communication request signal, cross certain hour and can remeasure current network coverage quality after at interval, just continue with bigger power emission communication request signal if also do not satisfy the demands, up to satisfying the demands or again till the bring to power.
Wherein, time-count cycle, the length of T1 can be provided with arbitrarily, generally can be located between the hundreds of millisecond to tens second, but the present invention was not limited to this concrete span.And rising step-length UpDeltaP and the preferred 0.1dB～3dB of decline step-length DeltaP, also can with watt or milliwatt office,, same such as 10 milliwatts to 2000 milliwatts, also be not limited to listed concrete span.In addition, preferably, the size of rising step-length UpDeltaP is greater than decline step-length DeltaP, and like this, system equipment can reach apace and satisfy the required public channel transmissive power of subscriber equipment demand, reduces the number of times of subscriber equipment emission communication request signal.
Fig. 4 shows the high-level schematic functional block diagram of the public channel power control system of the embodiment of the invention.This public channel power control system comprises that system equipment inserts entity and subscriber equipment, and wherein, antenna, receiver, transmitter and Service Processing Module etc. are the basic modules that wireless communication devices and user that it must have.
The public channel power control system of present embodiment has following characteristics:
1. system equipment is realizing having increased by two functional modules beyond the original function, i.e. communication request signal detection module and public channel power control module, wherein:
The communication request signal detection module is used for, and detects whether communication request signal is arranged from the received signal that receiver obtains, if detect communication request signal, then the communication request signal detection module need be notified the public channel power control module;
The public channel power control module is used for, and carries out public channel power control: on the one hand, the public channel power control module receives the information of Service Processing Module, judges whether to insert entity and need initiate new communication; On the other hand, the information of public channel power control module received communication request signal detection module has judged whether that communication request signal is detected.
Public channel power control module itself needs to safeguard a timer, output as the public channel power control module, the public channel power control module need be according to timer T1 time-count cycle control Service Processing Module and transmitter, reduce the public channel transmissive power of Service Processing Module even close transmitter, perhaps control Service Processing Module and recover the common signal channel processing, also need open transmitter if transmitter is in closed condition.
Concrete, if the public channel power control module in the time-count cycle of timer, receives the notice of communication request signal detection module or Service Processing Module, then after public channel transmissive power is controlled, timer is carried out timing again;
If when arriving the time-count cycle of this timer, both do not received the notice of communication request signal detection module, do not receive the notice of Service Processing Module yet, after then current public channel transmissive power being reduced a decline step-length or being reduced to zero, timer is carried out timing again.
2. subscriber equipment is at antenna, and receiver has increased the communication request signal generation module on these basic modules of transmitter and Service Processing Module, is used for when wireless coverage is second-rate, generates communication request signal and sends into the transmitter emission.
In addition, the wireless coverage quality detection module is the module of user that it must in the prior art, but the function to this module among the present invention is improved, if it is poor that current wireless covering quality measurement result display network covers, this information need be issued the communication request signal generation module, trigger the generation and the emission of communication request signal.Whether the communication request signal transmitter module need launch communication request signal to its feedback for the information of coming from the wireless coverage quality measurement module.
The wireless coverage quality measurement module is according to described feedback, if sent communication request signal, then the wireless coverage quality measurement module also need remeasure the wireless coverage quality on just now system and frequency, once more the wireless coverage quality is detected after crossing the certain hour interval, if still do not satisfy the demands, then notify described communication request signal generation module to launch communication request signal again; The communication request signal generation module is launched communication request signal with bigger emitted energy to system equipment after receiving the notice of launching communication request signal again of wireless coverage quality measurement module, until the emission maximum energy that reaches communication request signal;
If do not launch communication request signal, then think communication request failure on examining system and frequency just now can forward other frequency even other systematic survey wireless coverage quality to.
Be illustrated in figure 5 as according to network operation schematic diagram of the present invention.After adopting technical solution of the present invention, in sub-district 1, do not have subscriber equipment to communicate, public channel power can reduce to 0, has saved public channel transmissive power.In sub-district 2, all subscriber equipmenies all are near the center of housing estate zone, be not in the subscriber equipment of cell edge, this moment, common signal channel there is no need to launch with the maximum public channel power Pmax of configuration, but can reduce public channel transmissive power significantly.Sub-district 3,4, in 5, the subscriber equipment of communicating by letter is not in cell edge yet, can reduce public channel power significantly yet.In sub-district 6 and the sub-district 7, there is subscriber equipment to be in cell edge and communicating by letter, need launch with Pmax.As can be seen, with respect to Fig. 1, can obviously reduce the power consumption of common signal channel after the employing technical solution of the present invention.
Fig. 6 shows certain and inserts the time dependent schematic diagram of entity public channel transmissive power.Among the figure, transverse axis is the time, and the longitudinal axis is a public channel transmissive power.Wherein solid line is the common signal channel emission of conventional method, and the rated power Pmax with configuration launches always.Dotted line is the transmit power variation curve according to common signal channel under the power control of the present invention.Suppose just to begin with Pmax emission, crossed and do not detect communication request signal after the time T 1 and also do not insert the communication that entity is initiated, then public channel power is reduced DeltaP, reclocking then.If intermediate examination and measurement to communication request signal (such as communication request signal 1,2,3) then with transmitting power lifting UpDeltaP.Communication request (such as communication request 4,5,6,7) more for a long time inserts entity and can quickly recover to power P max at short notice.For communication request 8, insert entity and launched with Pmax, then only need to keep getting final product with the Pmax emission.When connecing entity initiation communication, also can directly return to or remain Pmax, reclocking then to power.From this curve example as can be seen, obviously lack through the common signal channel consumed power of power control than conventional method.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
