The priority that No. the 60/424th, 753, the U.S. Provisional Application case of the application's case opinion application on November 7th, 2002.
Technical field
The present invention relates to wireless telecommunications.
Background technology
The network that is used for wireless cellular telephony generally includes one group of fixed base stations of carrying out wireless telecommunications with mobile unit.In some cases, indivedual base stations may be separated from one another geographically.In other cases, an above base station may appear at a position.For instance, a website has three different transmitters, and each transmitter all covers the wide sector of difference 120 degree of a horizontal plane.In another example, a website has six transmitters, and each transmitter all covers the wide sector of difference 60 degree of a horizontal plane.The base station of being arranged is except orientation, and its feature (as transmission frequency) also may be different.
Though mobile unit is provided in the cellular phone usually, other device also can be equipped with support transmits sound and/or non-voice data with network mobile unit.These devices comprise PDA(Personal Digital Assistant), have portable or notebook computer and other electronic consumer devices integrated or accessory wireless modems (as with the pcmcia card form).Mobile unit also can be provided in the device of fixing substantially position operation, such as wireless local loop (WLL) unit, (POS) unit, point of sale or other family expenses or commercial appliances.
During operation, mobile unit is among a kind of in two kinds of patterns usually.When mobile unit did not participate in conversational communication (before beginning or receiving call, or after call finishes), it was with idle mode operation.When being in idle mode, mobile unit is to be used to indicate the page message of calling to listen to a selected channel (as a special frequency band, Code Channel and/or time slot).During idle mode, mobile unit also can be from network receiving control information (or with this message transmission to network).After receiving the page message of pointing to mobile unit, or when the user began call or other conversational communication (as the request to movable data transfer access such as support Email and/or access to the Internet), mobile unit entered dedicated mode.
For portable electron device (as mobile unit), general hope increases this device spendable time cycle before needs are changed power supply or charging.In the subsystem of mobile unit, radio frequency (RF) subsystem is wasted work rate normally.Therefore, general amount conduction time of wishing restriction RF subsystem.
A technology that is used for reducing the conduction time of RF subsystem during the idle mode at present is discontinuous reception technique.For instance, one is used the system of this technology to can be configured to make the page message of pointing to a specific mobile unit only to pass through Network Transmission in certain predetermined time interval.Therefore, the RF subsystem that is in the mobile unit of idle mode only need power up and prepare to receive and can cut off the power supply At All Other Times during these predetermined time intervals.
Sometimes, people wish that mobile unit listens to page message on different channels.For instance, the propagation path of the channel that mobile unit is monitored may change (as when mobile unit with respect to the Channel Transmission base station when a position moves on to another position), cause the reception of selected channel may become unreliable.Whether a different base station and which other base station should transmit the page message of pointing to mobile unit in order to make mobile unit and/or network can measure, and mobile unit is the monitoring channel quality relevant with other base station usually.Usually under idle mode (as supporting to receive page message and other ability that diffuses information continuously) and dedicated mode (as being supported in the ability that continues conversational communication between mobile unit and the network), all carry out this monitoring.
Perhaps, the task of monitoring other channel quality can cause problem.For instance, in idle mode, perhaps this task has increased the RF subsystem and has kept the time scale of energising, has therefore reduced the operating time between the battery charge twice.In dedicated mode, spend the time on other channel quality of monitoring to conflict with the time generation of carrying out other online required by task such as sound and/or non-data transmission in network telephony.
Summary of the invention
According to one embodiment of present invention, a kind of signal acceptance method is included in the first group of data value that receives during first time slot on first frequency band, and at the second group of data value that receives during second time slot behind first time slot on first frequency band.Between first and second time slot, this method comprises the signal sampling that receives on second frequency band and stores described sampling.Calculate the quality of signals value of reception based on described sampling.In some enforcements of the method, the calculating of the quality of signals value that receives being carried out based on the sampling of being stored allows to reduce the conduction time of RF subsystem (and allowing corresponding minimizing power consumption).In other was implemented, the calculating of the quality of signals value that receives being carried out based on the sampling of being stored made the RF subsystem can be used for other purposes.

Embodiment
At a multiple-access network such as the network that is used for cellular phone, the frequency spectrum of distributing to this network can be divided into a plurality of independent channels by several distinct methods.In TDMA (time-division multiple access (TDMA)) network, will be divided into the intersection group of a plurality of not overlapping slots the time, on the different time-gap group, have different efficient channels.In FDMA (frequency division multiple access) network, the Frequency Distribution of network is divided into a plurality of frequency bands, has different efficient channels on different frequency bands.In CDMA (Code Division Multiple Access) network, by using one or more quadratures or nearly orthogonal sign indicating number to encode, the communication on each channel all with other channel (its may be simultaneously and on the identical frequency band effectively) on communication different.
Fig. 1 is the flow chart of method according to an embodiment of the invention.Task T110 receives one group of data value on first frequency band.The signal sampling of task T120 (carrying out behind the task T110) on second frequency band, receiving.Task T130 (carrying out behind the task T120) receives another group data value on first frequency band.The signals sampling that task 140 (also carrying out behind the task T120) receives on based on second frequency band is calculated the mass value of received signal.The mass value of received signal then can local apply and/or transfer to another entity that is used to assess (as network).Can provide the enforcement support of method shown in Fig. 1 to visit an above wireless network, support above wireless network of monitoring, and/or support the transfer between heterogeneous networks.
A GSM compatible network is operated according to Global Telecommunication System (GSM) standard of being announced by ETSI (ETSI, Sophia Antipolis, France).This network be the TDMA network be again the FDMA network.In the GSM compatible network, the length of each time slot all be 15/26 millisecond (about 0.577 millisecond) and be labeled as the numeral 0 to 7.8 time slots of one group from 0 to 7 are called a frame and length is 120/26 millisecond (about 4.615 milliseconds), and each communication channel all is assigned to a particular time-slot number.In frequency domain, the frequency spectrum of distributing to network is divided into a plurality of frequency bands at the carrier frequency place of 200kHz at interval that concentrate on, and each channel is assigned to a special frequency band, and its uplink band and downlink band be 45MHz at interval.For instance, the distribution of 2 * 25MHz can be divided into 125 duplex band (each all carries nearly 8 duplex physical channels).Fig. 2 is an example with TDMA/FDMA scheme of n frequency band being divided into 8 time slots and frame.
When starting GSM compatibility mobile unit, its selection and preemption (promptly monitoring page message) is configured to the downlink band of broadcast channel (BCH).As shown in Figure 3, the BCH frequency band is loaded with several Different Logic control channels on its first time slot (time slot 0): frequency correction channel (FCH), synchronizing channel (SCH), Broadcast Control Channel (BCCH) and Common Control Channel (CCCH).These logical control channels transmit according to the multiframe timetable (comprising an idle frame) that just repeats every 51 frames.Fig. 4 is the example of this type of timetable.For fear of interfering with each other, adjacent base station (or sector) carries its BCH usually on different frequency bands.
Page message goes up transmission as piece at paging channel (PCH).Paging channel is a logic channel, and it is the part of CCCH.Each notifies from a phone call the time slot 0 that piece all occupies 4 successive frames, and in order to receive complete page message, mobile unit must receive whole.Each is notified from a phone call piece and all has a call group number, and each mobile unit also is assigned a call group number.The page message of pointing to mobile unit is transmitted in belonging to the call piece of its call group, and mobile unit need not to receive the call piece that does not belong to its call group.
The next one of one specific call group is notified from a phone call piece and may be occurred behind the interval of 2 to 9 multiframes, and is indicated as the value of the system parameters BS_PA_MFRMS that propagates on BCCH.Therefore, being in the RF receiving circuit of the mobile unit of idle mode should be approximately just power up and prepare to receive every 470 milliseconds to 2.1 seconds and notify from a phone call piece (Fig. 5).Between these intervals, the RF receiving circuit can cut off the power supply and reduce power consumption.
As above mentioned, wish that mobile unit is monitored and near the quality of other base station correlated channels.This monitoring can comprise the power stage of the signal that measurement is received on these channels.Design BCH comes to provide the basis for these measurements.Each time slot of BCH all comprises a data burst or room burst, makes that each time slot is all effective and it is idle not have time slot.Therefore, mobile unit can be asynchronous (promptly need not to obtain transmit base station synchronously) measures the received signal quality of BCH.
Except that the value of B parameter S_PA_MFRMS, BCCH also is loaded with the message that the identification neighbor base station carries the frequency of its BCH.If it is more suitable to measure (by mobile unit and/or network) channel ratio mobile unit present channel of preempting relevant with other base station, mobile unit will change and preempt this channel so.
During dedicated mode, the monitoring of other channel quality is also being continued.If it is more suitable that mensuration (by mobile unit and/or network) channel ratio relevant with other base station carried the channel of conversational communication at present, carry out turning-over operation so, wherein the conversational communication with mobile unit will switch to new base station.Therefore, the interior following data burst of same communications session may be at different channels or is not even received on the same frequency.
Recently, the 3GPP standard of definition UTMS (global system for mobile communications) operation is announced (the UTMS standard is also announced by ETSI).The UMTS network is the cdma network that also may have TDMA and/or FDMA structure.Can be called multi radio access technique (multi-Radio Access Technology) mobile unit with the mobile unit that GSM or UMTS network carry out communication.In at least some are implemented, the UMTS network can with GSM network (for example have contiguous or even overlapping coverage) and deposit geographically.
The nearest variation (as technical specification 05.08, renumbeing is 45.008) of GSM standard allows to be handed over to the UTMS network from the GSM network.The multi radio access technique unit that these standard-requireds are connected to the GSM network is carried out an indication from this network and is selected or transfer UMTS unit (except GSM unit on every side) around assess once more for possible.
As mentioned above, can carry out with asynchronous power measurements the monitoring with the quality of neighbor base station correlated channels in the GSM network.For channel relevant in the UMTS network with the base station, according to the mass parameter value of called after RSCP (received signal code power) and between the threshold value that receives on the BCCH, done relatively assess channel quality.The RSCP parameter itself is the function of other two parameters:
RSCP＝RSSI×CPICH?Ec/Io
Parameters R SSI (received signal intensity index) is based on asynchronous measurement and can be evaluated under the situation of no synchronizing information.Unfortunately, the ratio (Ec/Io) of the pilot tone of parameters C PICH Ec/Io-CPICH (Common Pilot Channel) energy (pilot energy) and total energy--be synchro measure.In order to assess CPICHEc/Io, must discern the code synchronisation (code timing) of each pilot signal to be assessed.
3GPP standard code CPICH can utilize a coding in 512 main scramblers of difference.The type sequence of each code all has the length of 38,400 chips and 10 milliseconds cycle.These standards stipulate that also the multi radio access technique mobile unit that carries out communication with the GSM network can possess three kinds of different monitoring frequencies, and possess nearly 32 in order to unique scrambler (unique scramblingcode) that each frequency is set, sum 64 UMTS base station the most nearly.Therefore, in short cycle (as powering up in the time), can require multi radio access technique mobile unit to measure and reach the synchronous of 64 different scrambling codes descramblings at 30 seconds.
For each scrambler is set, must the many different synchronous hypothesis of assessment.Yet, wish to save power the effective time that reduces the RF subsystem, and wish to avoid interference other operation of mobile unit.
In the method according to one embodiment of the invention shown in Fig. 1, two groups of data values all receive on first frequency band.Receiving between these two groups of data, the signal sampling that on second frequency band, receives.Then calculate the mass value of received signal based on the signals sampling that receives on second frequency band.In the method being applied to an exemplary embodiments of mobile unit, when the RF receiving circuit disconnects, carry out processing (comprising the calculating of received signal quality value) to sampled signal, can and/or reduce and broadcast service time in conjunction with power like this.
Fig. 6 is the flow chart of method shown in Fig. 1, comprises task T110 and T130 concrete enforcement T112 and T132 separately.Task T112 receives a part of transfer of data on first frequency band.The signal sampling of task T120 (carrying out behind the task T110) to receiving on one second frequency band.Task T132 (carrying out behind the task T120) receives another part (as the next part) transfer of data on first frequency band.Task T140 (also carrying out behind task T120) calculates the mass value of acknowledge(ment) signal based on these samplings.This value can be expressed as absolute term (as the predetermined characteristic value of received signal, such as power) or relative term (as the value that concerns between indicating predetermined signal characteristic value and one or more predetermined thresholds).For instance, for the measurement relevant with the UMTS channel, this value can surpass threshold value for binary value, the indication RSCP whether RSCP, indication RSCP surpass threshold value or fall the value that concerns between the value of the degree under the threshold value or indication RSCP and several predetermined threshold (for example surpass threshold value 2 but be lower than threshold value 1).The received signal quality value can transfer to another entity (no matter being actual conditions or the incident of periodically also being based on) such as network and/or be applied topically to channel and select in the control decision.
In one example, task T112 and task T132 receive the continuous burst of a call piece.In another example, task T112 and task T132 receive the continuous burst of call or other conversational communication.In another example, task T112 and task T132 receive the burst (vice versa) of BCCH and PCH respectively.
In some applications, the RF receiving circuit that may wish mobile unit begins to finish still to continue to power up to task T130 from task T110.For instance, the interval between two tasks can be short to make be sent to the RF receiving circuit power cycle infeasible.When mobile unit participated in the effective conversational communication, this situation can occur in some systems.Perhaps, mobile unit can be carried out special duty (as receiving message and/or the signal quality information on other channel) in the interval that requires the RF receiving circuit to power up.In other was used, RF receiving circuit power-off time can be at least a portion at interval between finish the work T110 and the beginning task T130.Fig. 7 is a sequential chart of implementing, wherein task T120 task T110 carried out that the back takes place and simultaneously the RF receiving circuit still be in and power up.Fig. 8 is a sequential chart of implementing, and wherein task T120 takes place before the RF receiving circuit has powered up back and task T130 execution.
In the pilot signal of propagating by the UMTS base station, always have 10 milliseconds main scrambler, and the selection of collection period is a completely random.In one uses, wherein task T120 utilizes one-period sign indicating number (as the CDMA signal) to a signal sampling that covers, propagates or upset, and may need task T120 to gather sampling (promptly only with the corresponding observation of a part of code sequence) in less than the cycle of whole code period.For instance, this characteristic can be applicable under the situation of the crosscorrelation coefficient very low (as between the pilot signal of UMTS network) between different scrambling codes.This implements possible advantage can comprise that memory requirement reduces and power consumption reduces.In an example, used the collection period of 1 millisecond of every frequency.Fig. 8 A is the application of this example aspect a part of UMTS pilot signal of collection.In Another Application, wish that collection is longer period.
Fig. 9 is the calcspar of equipment 100 according to an embodiment of the invention.Radio-frequency (RF) receiving circuit 110 receives RF signal (as from an antenna) and carries out such as filtration and amplifying signal and handle operation and the output received signal.Received signal can be in radio frequency maybe can be downconverted to intermediate frequency or base band.Circuit 110 can comprise that one or more use the integrated circuit of making such as CMOS, GaAs, SiGe or strained silicon technology.Circuit 110 also can comprise the discrete elements such as filter and/or inductor.
Sampler 130 is sampled to received signal to produce sampled signal.May need sampler 130 to sample to received signal (as according to nyquist sampling theorem) with the frequency of 2 times of the frequencies that are not less than the highest frequency component of waiting to differentiate received signal.For instance, for the signal that receives in base band, may wish that sampler 130 samples to received signal with data rate twice or higher speed.For the CDMA signal that receives in base band, may wish that sampler 130 samples to received signal with code rate twice (chip * 2) or higher speed.
Sampler 130 can use such as the technology of CMOS, GaAs, SiGe or strained silicon and make.In some cases, sampler 130 can be included in the integrated circuit that also comprises at least a portion RF receiving circuit 110.Sampling rate (variable) can according to such as memory capacity (higher sampling rate may cause the memory requirement of identical sampled signal length is increased) and the consideration that is used for assembling the technical limitations of sampler 130 select or design.
Memory cell 140 receives and the store sample signal.Memory cell 140 can comprise a RAM (random access memory) element, such as DRAM (dynamic ram), SRAM (static RAM (SRAM)), quickflashing RAM or ferroelectric or other magnetic ram.Memory cell 140 can be manufactured into the individual packages element and maybe can be included in the integrated circuit or encapsulate with integrated circuit, and described integrated circuit comprises another assembly of equipment 100.
Calculator 150 is retrieved at least a portion sampled signals and is calculated the mass value of received signal based on described sampling.For sampled signal wherein is the application of a CDMA signal, and calculator 150 can be carried out existence and the position that associative operation be measured a particular extension sign indicating number or scrambled code to sampling.The receive frequency of controller 120 control RF receiving circuits 110.
Each calculator 150 and controller 120 all can be configured as one or more array of logic elements (for example, being included in application-specific integrated circuit ASIC or the on-site programmable gate array FPGA).Perhaps, calculator 150 and controller 120 can be construed as in one or more array of logic elements (embed in the ASIC or be programmed in processing core in the FPGA such as a microprocessor, a microcontroller or) and go up a plurality of command sequences of carrying out.The power that one array of logic elements (a for example microprocessor) consumes is usually far below the RF receiving circuit.
Figure 10 is the calcspar of the embodiment 102 of equipment 100, and calculator 150 outputs one signal is given controller 120 in equipment 100.In a kind of pattern of equipment 102, calculator 150 signal quality estimation values of output (for example measurement result of power level signal) are given controller 120, are determined whether to change the receive frequency of RF receiving circuit 110 by controller 120.In another pattern of equipment 102, calculator 150 instruction control units 120 change the receive frequency of RF receiving circuit 110 based on the signal quality estimation value.
In an illustrative application, an embodiment of equipment 100 is used for catching sample for processed offline.For instance, can catch implementing this between the time slot of a call group and/or between the call group.
For the CDMA Signal Processing, calculator 150 can comprise a searcher well known in the prior art (for example with hardware and/or form of software).Because a kind of searcher embodiment (its can be simultaneously for four different codes tests nearly nearly 64 differences suppose synchronously) with 256 times of chip rate run time versions search, so it is called as a 256x searcher.Other case that can be applicable to that quick search strategies in the calculator 150 are disclosed in entrusted agent's application number is in the U.S. patent application case of applying for of No. 010334 (METHOD ANDAPPARATUS FOR W-CDMA HANDOFF SEARCHING) and No. 010478 (SEGMENTED CDMA SEARCHING).
Communications between mobile unit and GSM base station (as during dedicated mode) occurs in the 26 frame multiframe structures of control channel but not in the 51 frame multiframe structures.In 26 frame structures, frame 0 to 24 all effectively and frame 25 is to leave unused.
As mentioned above, may be during dedicated mode the monitoring and controlling channels quality.Also may need multi radio access technique mobile unit to monitor and the quality of being close to UMTS base station correlated channels.Yet, in 25 valid frames of communication multiframe, do not exist and can monitor the UMTS channel and reach 10 milliseconds of holocyclic idling cycles of code, unless not executive communication transmission and/or receive during this cycle.Though idle frame can be used to reduce the UMTS monitoring to the communication channel Effect on Performance, idle frame can not be used for this monitoring, carries out other online task because mobile unit is construed as usually during idle frame.
As shown in figure 11, the time slot of the down link band in the GSM network with respect to the time-slot delay of corresponding up link band two time slots.Figure 12 is the sequential chart of three bursts of the conversational communication between GSM base station and mobile unit.Two time slot periods by the communication bursts of base station (on the down link band) transmission with by the next communication bursts of mobile unit (on the up link band) transmission between effective.This postpones to allow mobile unit to change its transceiver (generally including the RF receiving circuit) takes the up link band to from down link frequency.Four time slot periods by the communication bursts of mobile unit transmission with by the next communication bursts of base station transmits between effective.
Therefore, under dedicated mode, four time slots (or about 2.3 milliseconds) periods is effective between a transmission time slot finishes to begin with next receiving slot.As mentioned above, (for example monitor the UMTS pilot channel) under particular condition, collection period may be shorter than code period.How according to an embodiment of the invention Figure 12 A explanation method is applied in as shown in Figure 12 the situation, this makes the RF receiving circuit can be used for other online task during idle frame by execution acquisition tasks T120 between finishing at a transmission time slot to begin with next receiving slot thus.
