Abstract
According to the invention, the use of several narrow-band paging channels enables the data rate to be reduced thereby creating appropriate conditions for further reducing power consumption of mobile communication terminals in stand-by mode without impairing accessibility.
Description
For the communication terminal that moves, for example the current drain under the idle condition (present mode) is to depend on receiving-member how long need be turned off to a great extent for cellular phone terminal.This time is provided by system for traditional mobile radio telephone network.This time is long more, and energy consumption is just more little, and the average time (response time) of connection next call is also just long more.That is to say that the energy consumption of terminal equipment under idle condition keeps more for a short time, then system responses is just slow more.This situation utilizes time-division multiplexing method to provide, and utilizes signaling channel of this time-division multiplexing method (be said paging channel, also be represented as PCH in GSM standard) to be divided into paging subchannel (being said paging sub-channels).The paging information arrangement in time of different paging subchannels is to be sent out by communication network (in other words for example, by a base station sub-system).Each wireless terminal all has been assigned with a paging subchannel.Therefore receiver must only be switched on after such time interval, and the information corresponding to the paging subchannel in this time interval is launched away.Though so the current drain of this terminal has been reduced, it is long more that receiver is turned off the time, the average duration of connecting next call is just big more.
The present invention improves according to such target, guarantees when promptly energy further reduces that the average time (response time) of connection next call is as much as possible little.This task is to utilize the method for transmitting information between communication network and communication terminal that obtains according to claim 1 and utilize the communication terminal that obtains according to claim 4 to be solved.
This current invention is based on such idea, with reducing turn-on time of the receiver under the idle condition rate of data signalling.Because the rate of data signalling that the input of the power of a communication terminal can utilize transmission information to be adopted is reduced, then realized reducing of power input in this method of reception period.No matter yet well-known hereto method is just in idle condition or do not exist at the basic communication terminal of the input power of reception period, so according to having only the Mean Input Power under the idle condition to be reduced the turn-on time that receiving-member is short, can realize the reducing of (moment) input power under the reception period idle condition by the present invention.Time of reception (turn-on time of receiver) can be more longer than the time of reception of existing system for the present invention, and average time or the energy consumption of therefore connecting next call can be reduced.
Preferred other structures of the present invention provide in the dependent claims.
This thought of the present invention, be that the input power of communication terminal under the reception period idle condition is reduced by adopting a less rate of data signalling, can certainly with a temporal restriction or time of reception reduce match, reach further and save energy.By one of relevant parameter suitable selection this of mean value, the energy consumption under the idle condition and the sensitivity of receiver can be enhanced simultaneously turn-on time.
Can provide a lot of narrow band channels according to a practical solution of the present invention, each such channel all is to be assigned with at message transmission under idle condition in the communication terminal cohort here.This channel can be demarcated each other according to time range or frequency range or according to the mode that other professional is familiar with.Several this channels or other narrow band channel also can be applied to the message transmission from the communication terminal to the communication network.
The present invention can be got across by means of following block diagram:
Fig. 1 has provided an actual form of the present invention in the mode of summary, and paging channel is divided into a plurality of arrowband paging subchannels in this actual form, and these channels were adopted simultaneously according to the time.
Fig. 2 provides an actual form of the present invention in the mode of summary, and paging channel is divided into a plurality of arrowband paging subchannels in this form, and these channels are adopted successively or adopted simultaneously in time sometimes.
Fig. 3 has provided the combination of the actual form of describing among Fig. 1 and Fig. 2 of the present invention in the mode of summary.
Fig. 4 has provided a preferred actual form according to communication terminal of the present invention in the mode of summary.
Following the present invention is by means of a preferred examples and utilize block diagram to be described in detail.
The present invention designs and adopts an arrowband paging channel or a plurality of arrowbands paging channel, the bandwidth of this one or more channels to be far smaller than real adopted or the desired bandwidth of conversation transmission.Possible realization is presented in Fig. 1 in the mode of summary.Utilize the paging subchannel that the time is provided with, if what adopt is several traditional mobile wireless electric standards, then a paging channel (PCH) is divided into arrowband paging subchannel (PSCH1, ..., PSCHn), this subchannel be positioned on the different sub-bands of paging channel frequency band (PB) (PSB1 ..., PSBn).The current bandwidth (PB) of gathering leaves of a book that is used for that this is complete is divided into n the sub-band with corresponding less bandwidth.
Fig. 2 has provided the particularly advantageous actual form of another one of the present invention, and the paging subchannel utilizes the separation of frequency range (f) and one to utilize the separation of time range (t) to be mixed together in this form.Here a paging subchannel is defined by a frequency range (PSB) and a time range (PTS).Known by means of top description professional, determine which kind of actual form of the present invention be favourable will be according to its quality standard (sensitivity of receiver, energy requirement under the idle condition or connect one call out a terminal equipment average time, or the like) carry out preferred.
If this receiver (communication terminal) for example is to have in the public transport of strong shielding at a vehicle body, perhaps in a remote rural area away from next base station and only transmit a character string (paging with certain meaning, short message service) time, will have precedence over requirement to system response time for the requirement of receiving sensitivity.The present invention can have reaction very flexibly for this different situation, and here a communication terminal can provide suitable paging subchannel according to the application scenario, and the characteristic of this channel meets this environment as much as possible.In Fig. 3 the description of summary a this scheme.Here paging channel is to be lumped together by different paging groups of subchannels, and this paging subchannel is to be divided into various piece according to its occupied time range size.Description according to the front can know that the paging subchannel also can be divided according to its frequency range size (that is to say according to bandwidth).The integrated paging subchannel that can realize wideband by basic paging subchannel for instance.Therefore communication terminal can be according to optimizing its energy consumption under idle condition by network predetermined data transfer rate and current condition of acceptance.In addition communication terminal can make its reply the paging calling that depends on transmission conditions and method of calling (voice, data, SMS).
The present invention can have other way of realization, and the division of paging channel is suitable for the subchannel of instantaneous gain in the communication network, that is to say suitable cell.
Communication terminal according to above-mentioned invention is to control by this method of characteristic that makes its reception bandwidth meet its given paging subchannel.So designed a digital filter in optimal way, its parameter (that is to say, for example its filter factor) can be changed when jumping to other reception bandwidth without a doubt.This digital filter for example can realize that this software is to operate in the appropriate signal processor by suitable software approach.
The reducing of paging subchannel bandwidth of each terminal equipment group distributed in utilization, obtained reducing of peak data transfer rate naturally.Then said method is desirable just in view of the input power of terminal equipment thus reduces too.But utilize less established data amount of data transmission rate transmission to require the corresponding long time.Be particularly advantageous below this point, promptly constructing one utilizes paging channel or its subchannel to come information transmitted, just do not have the terminal called so that can identify one, it is not called out according to the fragment of the transmitting time of the paging subchannel of its distribution.This terminal can be turn-offed reception and resetted until (perhaps after a while) next time of its paging subchannel that is assigned with in this case.Further reduced according to this mode energy consumption, and can not be reduced the response time.
Such structure can be as the realization of getting off, and all are by the inventory of calling terminal promptly to construct one when paging subchannel transmitting time begins.Then-if other information of important-relevant device would at first be sent.Also can handle a transmission that has the calling party's of institute Subscriber Number according to other way of realization of one of the present invention.Therefore in corresponding communication terminal, provided and be used for realizing " in real time " method relatively; Receiver is not turned off and at first recloses the transmission of next Subscriber Number under optimal way for first that indicates matches.Here being transmitted under the optimal way of Subscriber Number is that the time scale line that basis is determined is carried out.
The reducing of data transmission rate resembles the front and describes that pointed that works is used to reduce input power and therefore reduces energy consumption.Also can realize reducing to connect the average time of a calling by determining on the short time scale line of paging subchannel.Last also can utilize the paging subchannel bandwidth reduce to improve receiver sensitivity.Bandwidth by arrowband paging subchannel, suitable selection of data transmission rate and time reticule and the suitable configurations by respective communication terminal receiver are possible by situation below the description of front, if promptly there is this situation can realize about input power, the desirable adjusting between the phase cross-demand of temporal realizability and receiving sensitivity.
The reducing of terminal equipment input power utilizes less data transmission rate for example by reducing reactive current at receiver stage or realizing by turn-offing all amplification pieces.If it is very high that receiver sensitivity is hoped to reach, then for example be achieved by the reactive current of raising receiver stage or by the redundant code that transmits data.The combination that method by this or effect same makes up the predeterminated target of each hope just is implemented.
