With the development of communication technology, wireless terminal has evolved to the stage of intelligent terminal, wherein most of wireless whole End is portable smart phone, and the most key processor is application processor and baseband processor in smart phone.

Wherein, application processor is considered as a general processor, and various Games Softwares, application software etc., which work in, answers Use processor.Application processor supports the operating systems such as IOS system, android system, and support desktop system, file management, when Between the functions such as manage, support management to equipment such as GPS module, bluetooth, WiFi, also with to working in application processor Various softwares provide location-based service and connection service.

Baseband processor provides the communication function on basis for wireless terminal, can support the systems such as GSM, WCDMA, LTE, base band Processor and its matched peripheral equipment include radio frequency chip, analog-digital chip, power amplifier, antenna etc., Base-Band Processing Device provides the functions such as the complete modulation /demodulation of GSM, WCDMA, LTE, encoding and decoding, protocol processes control, to support complete nothing The functions such as line communication, mobile management.

Referring to Fig. 3, it illustrates application processor in wireless terminal and its peripheral chip, circuit and baseband processor and allusion quotations The block diagram of type peripheral chip, circuit.Wherein, there are communication, Ke Yitong between baseband processor and application processor Cross HSIC protocol communication (the typically plug-in mode of baseband processor, i.e., using baseband processor and application processor as two kinds Different processors), it can also communicate that (this mode applies in general to Soc form, i.e. Base-Band Processing by shared drive mode Device, application processor are integrated on a chips), it also include other communication modes, the present embodiment is not to application processor and base Communication mode between provided with processor makees specific limit.

The power consumption of wireless terminal especially portable equipment (mainly smart phone) directly affects user experience, usually Application processor and baseband processor can all generate power consumption, the power consumption when equipment such as peripheral display screen work when working normally It measures also bigger.In order to reduce the power consumption of wireless terminal, while user's normal use is not influenced, at application processor and base band Reason device provides various ways, for example user does not use for a period of time, and application processor directly will do it screen operation of going out, such as 3GPP agreement has formulated discontinuous received standard, with control baseband processor in an idle state it is rhythmic be transferred to sleep when Between, to save electric power.However, the power consumption of wireless terminal is still very big even with these modes.

In wireless communication field, when wireless terminal is in survey of the idle state starting to alien frequencies adjacent area and different system adjacent cell Amount will increase the power consumption of wireless terminal, and the adjacent area measured is more, and the increased power consumption of institute is more significant.For example, if wireless terminal Only serving cell is measured, standby current may be 5~10mA；If to serving cell while measuring, Also 4~6 alien frequencies and different system adjacent cell are measured, serving cell is measured even if being lower than to the measurement frequency of adjacent area Frequency, standby current may also will increase to 15~20mA.Fig. 4 is that wireless terminal does not start alien frequencies or isosystem measurement Standby current waveform diagram, Fig. 5 are the standby current waveform diagram that wireless terminal starts alien frequencies or isosystem measurement, pass through comparison diagram 4 With Fig. 5 it is found that after introducing alien frequencies or isosystem measurement, standby current width broadening, even if standby current is still shown after average It writes and increases.By taking battery capacity is the smart phone of 2500mAh as an example, setting smart phone does not carry out other power consumption work, only single Pure standby, in the case where smart phone does not start alien frequencies or isosystem measurement, the standby current of smart phone may be 8mA；In the case where smart phone persistently starts the measurement to multiple adjacent areas, the standby current of smart phone be will be increased to 15mA, in 8 hours stand-by times, smart phone is by the electricity of more consumptions 2.2%.

The embodiment of the invention provides a kind of adjacent cell measurement method, this method is by applied field accessed by application processor Scape Information application is into the measurement process to adjacent area, to achieve the purpose that save electric energy.Referring to Fig. 6, side provided in this embodiment Method process includes:

601, when being in idle condition and detecting that the signal of serving cell changes, wireless terminal is to serving cell And the signal of adjacent area measure.

Wherein, wireless terminal can have the equipment of communication function for smart phone etc..Wireless terminal to serving cell and The process that the signal of adjacent area measures, includes the following steps:

6011, it when wireless terminal resides in serving cell, and establishes after paging channel, wireless terminal monitors service in real time The paging that cell issues, if there is the paging for being handed down to itself in the paging that serving cell issues, wireless terminal by play come The modes such as electric bell sound, vibration, which remind user currently, new incoming call.

6012, during being resident on the serving cell, wireless terminal receives standard according to discontinuous, does not connect every one The period is received in continued access, carries out one-shot measurement to the signal of serving cell, and enter sleep state after a measurement, in a sleep state without Line terminal stops the measurement to serving cell.Wherein, discontinuously receiving the period includes time of measuring and sleeping time.

6013, when the signal conditioning for detecting serving cell changes, the signal of serving cell is deteriorated, and wireless terminal opens The measurement of the dynamic signal to adjacent area.Wherein, adjacent area includes and alien-frequency district of the serving cell in same system and small with servicing Different system cell etc. of the area in not homologous ray.

Herein it should be noted that wireless terminal is when the signal to adjacent area measures, wireless terminal also can be to service The signal of cell measures.

6014, wireless terminal judges whether the signal of any adjacent area is full according to the signal of serving cell and the signal of adjacent area Sufficient reselection conditions obtain the broadcast of adjacent area transmission if meeting reselection conditions, and reside in the adjacent area, to obtain base station The service provided by the adjacent area；If being unsatisfactory for reselection conditions, wireless terminal continues to survey the signal of serving cell Amount.

Wherein, cell re-selection conditions include: the signal strength of serving cell when wireless terminal is resident on the serving cell Lower than the first threshold value, if there are the cell of high priority in adjacent area, and the signal strength of the cell of high priority is higher than the Two threshold values, then by wireless terminal gravity treatment to adjacent area；If there are the cell of low priority in adjacent area, and low preferential cell Signal strength is higher than the second threshold value, then by wireless terminal gravity treatment to adjacent area.Wherein, it is wireless that the first threshold value, which is serving cell, Terminal provides the smallest signal strength when normal service, and the second threshold value can be by network configuration.

6015, after being spaced multiple discontinuous reception periods, wireless terminal, which is again started up, measures the signal of adjacent area, Wireless terminal judges whether the signal of any adjacent area meets reselection conditions according to the signal of serving cell and the signal of adjacent area, such as Fruit meets reselection conditions, then is switched to the adjacent area, if being unsatisfactory for reselection conditions, continues to survey the signal of serving cell Amount, after step 6015 repeats more wheels, if any adjacent area does not meet reselection conditions still, and the signal of serving cell is steady It is fixed, then it will execute step 602.In the present embodiment, signal stabilization refers to signal fluctuation range within the specified range, and multiple Signal strength is not in attenuation trend in the discontinuous reception period.

602, wireless terminal obtains application scenarios information.

When detecting the signal stabilization of serving cell, the baseband processor in wireless terminal can be sent to application processor Application scenarios information acquisition request, after application processor receives application scenarios information acquisition request, from modules such as device drives Application scenarios information is obtained, and the application scenarios information that will acquire is sent to baseband processor, gets as wireless terminal Application scenarios information.Wherein, application scenarios information includes system time, screen display state, motion state etc., and the screen is aobvious Show that state includes bright screen state and dark screen state etc., motion state includes motion and standstill etc., and the present embodiment does not show screen State and motion state make specific limit.

603, wireless terminal judges serving cell according to application scenarios information, the signal of the signal of serving cell and adjacent area Signal and adjacent area signal whether meet measurement delay condition, if so, execute step 604, if not, execute step 605.

Based on accessed application scenarios information, wireless terminal is in the signal of the signal and adjacent area that judge serving cell When no satisfaction measurement delay condition, following steps can be used:

6031, wireless terminal judges whether wireless terminal is in the state of continuing working according to application scenarios information.

The application scenarios information of usual wireless terminal, is able to reflect the working condition of wireless terminal, for example, if wireless whole End is in dark screen state, and system time is morning, and wireless terminal is in stationary state, and user is typically in sleep shape at this time State not will use wireless terminal, thus can determine that wireless terminal is not in the state of continuing working；If wireless terminal is in bright screen State or system time non-morning or wireless terminal are in motion state, and user is not in sleep state at this time, using wireless The probability of terminal is larger, thus can determine that wireless terminal is in and continue working state.

If 6032, wireless terminal is not in the state of continuing working, wireless terminal determines signal and the adjacent area of serving cell Signal meet measurement delay condition.

It is found in the research to wireless terminal, state is continued working when wireless terminal is in, to serving cell and adjacent area It is necessary for carrying out test constantly, however when the non-place of wireless terminal continues working state, for example, morning user is not used wirelessly eventually End, if adjacent area is unsatisfactory for reselection conditions, wireless terminal will persistently be measured adjacent area, and will consume nothing to the measurement of adjacent area The electricity of line terminal, and then influence the cruising ability and user experience of wireless terminal.Therefore, when sentencing according to application scenarios information Disconnected wireless terminal out is not in the state of continuing working, and wireless terminal can determine that the signal of serving cell and the signal of adjacent area meet and survey Measure delay condition.

In the present embodiment, measurement delay condition further include serving cell signal fluctuate within the specified range, service it is small The service that area provides meets the difference between the business demand of wireless terminal, the signal strength of serving cell and the signal strength of adjacent area Value is greater than at least one of default value.Wherein, specified range 0db~1db, 0db~2db, 0db~3db etc., the present embodiment Specific limit is not made to the size of specified range.Default value can be 5dbm (decibel milliwatt), 6dbm, 7dbm etc., this reality It applies example and equally specific limit is not made to the size of default value.Serving cell is the service that provides of wireless terminal because of wireless terminal It is presently in the business of reason and different, if wireless terminal is currently just handling talk business, serving cell is what wireless terminal provided Service is session services, judges whether service that wireless terminal provides meets the business demand of wireless terminal and refer to serving cell energy No guarantee wireless terminal and call opposite end normal talking；If wireless terminal currently just handles internet business, serving cell is nothing The service that line terminal provides is service on net, judges whether service that wireless terminal provides meets the business demand of wireless terminal and be Refer to that can serving cell guarantee wireless terminal normal load webpage, broadcasting video etc..

Postpone condition based on measurement described in above content, if detecting the signal of serving cell within the specified range Fluctuation, then wireless terminal determines that the signal of serving cell and the signal of adjacent area meet measurement delay condition, for example, specified range is The fluctuation range of 0db~3db, the signal of serving cell are 2.1db, since the signal of serving cell fluctuates within the specified range, Accordingly, it can be determined that the signal of serving cell and the signal of adjacent area meet measurement delay condition；If the service that serving cell provides Meet the business demand of wireless terminal, then wireless terminal determines that the signal of serving cell and the signal of adjacent area meet measurement delay item Part, for example, the current business of wireless terminal is to send SMS service, if wireless terminal can smoothly receive and dispatch short message, The signal of the signal and adjacent area that can determine serving cell meets measurement delay condition；If signal strength and the adjacent area of wireless terminal Signal strength between difference be greater than default value, then wireless terminal determine serving cell signal and adjacent area signal meet Delay condition is measured, for example, default value is 1dbm, the signal strength of serving cell is -105dbm, the letter of low priority adjacent area Number intensity is -103dbm, since the difference between the signal strength of serving cell and the signal strength of adjacent area is 2dbm, is greater than pre- If numerical value, accordingly, it can be determined that the signal of wireless terminal and the signal of adjacent area meet measurement delay condition.

It, can be with when above-mentioned deterministic process refers to that the serving cell where wireless terminal and wireless terminal meets a condition Judge serving cell signal and adjacent area signal meet measurement delay condition, certainly, above-mentioned condition can also in any combination, It is that can determine that service is small when the serving cell where wireless terminal and wireless terminal meets above-mentioned at least two condition The signal in area and the signal of adjacent area meet measurement delay condition, wouldn't repeat herein specific combining form.

Preferably, in order to improve judgement precision, wireless terminal can fluctuate within the specified range in the signal of serving cell, and The service that serving cell provides meets the business demand of wireless terminal, and the signal strength of the signal strength of serving cell and adjacent area Between difference be greater than default value, and wireless terminal is not in when continuing working state, determines signal and the neighbour of serving cell The signal in area meets measurement delay condition.

604, wireless terminal extends the measurement period to adjacent area.

When the signal for the signal and adjacent area for judging serving cell meets measurement delay condition, wireless terminal passes through extension To the measurement period of adjacent area, to reduce power consumption, the cruising ability of wireless terminal is improved.Wherein, measurement period is to use The period that the signal of adjacent area is measured of the protocol definitions such as 3GPP363133.

Wireless terminal is suitably prolonged when extending the measurement period to adjacent area in combination with the application scenarios information got It is long.For example, system time is the time in morning, and wireless terminal is in stationary state, then may be used if wireless terminal is in dark screen state The measurement period of adjacent area will be extended to 20 minutes；If wireless terminal is in dark screen state, system time is the non-time in morning, Wireless terminal is in stationary state, then can will extend to 5 minutes to the measurement period of adjacent area.

It should be noted that it is above-mentioned when the signal of serving cell and the signal of adjacent area meet measurement delay condition, wirelessly Terminal only extends the measurement period to adjacent area, does not extend the measurement period to serving cell, that is to say that wireless terminal still can The signal of serving cell is measured every discontinuously receiving the period.

After extending to the measurement period of the signal of adjacent area, if the signal fluctuation range of serving cell is more than specified model It encloses or the signal quality of serving cell is deteriorated, wireless terminal again will measure adjacent area according to measurement period, to guarantee Quality services can be provided for user.Certainly, if detecting that the signal fluctuation range of serving cell is larger, wireless terminal can The appropriate measurement period shortened to the signal of adjacent area takes for example, being 1 minute to the measurement period of the signal of adjacent area when measuring After the signal fluctuation range for cell of being engaged in is larger, wireless terminal can will be foreshortened to the measurement period of adjacent area 30 seconds etc..

605, wireless terminal is measured according to signal of the measurement period to adjacent area.

After the signal of the signal and adjacent area of judging serving cell is unsatisfactory for measurement delay condition, wireless terminal will be by It is measured according to signal of the measurement period to adjacent area.

The process that above-mentioned wireless terminal measures the signal of adjacent area, reference can be made to CELL1 is wireless in following Fig. 7, Fig. 7 The serving cell of terminal, CELL2 be an adjacent area, although only showing an adjacent area CELL2 in Fig. 7, as long as not and represent one A adjacent area, the actually adjacent area of serving cell may be multiple.

Referring to Fig. 7, when wireless terminal resides in CELL1, wireless terminal establishes paging channel, and monitors what CELL1 was issued Whether the paging that is handed down to itself is had in paging.During being resident on the serving cell, wireless terminal is received every discontinuous Period measures the signal of CELL1.After the signal conditioning of serving cell is deteriorated, wireless terminal starts the letter to CELL2 Number measurement, in the measurement process wireless terminal can the signal of signal and CELL2 to CELL1 measure.Wireless terminal According to the signal of the signal of CELL1 and CELL2, judge whether CELL2 meets reselection conditions, if CELL2 meets reselection conditions, The process for obtaining CELL2 broadcast is then jumped to, if CELL2 is unsatisfactory for reselection conditions, is being spaced multiple discontinuous reception weeks After phase, wireless terminal is again started up the measurement to adjacent area, if CELL2 is unsatisfactory for reselection conditions, continue to the signal of CELL1 into Row measurement, after repeating more wheels, if any adjacent area does not meet reselection conditions, and the signal stabilization of CELL1 still, then wirelessly The baseband processor of terminal is to application processor sending application scene information acquisition request, when receiving application scenarios acquisition of information After request, application processor obtains the application scenarios information such as system time, screen display state, movement state information, and will The application scenarios information got is sent to baseband processor, and the baseband processor in wireless terminal is according to the signal strips of CELL1 Part and application scenarios information judges whether to suspend or extend the measurement period to CELL2, if it is not possible, then continuing pair The signal of CELL1 and the signal of CELL2 measure, if it is then stopping or elongating the week of the measurement to the signal of CELL2 Phase, during stopping or extending the measurement period to the signal of CELL2, wireless terminal only surveys the signal of CELL1 Amount.When the fluctuation range for the signal for monitoring CELL1 is in continuous worsening trend, nothing more than the signal of specified range or CELL1 Line terminal is by the measurement according to measurement period restarting to the signal of CELL2.

Method provided in an embodiment of the present invention, the scene that wireless terminal intelligent recognition is presently in, in the letter of serving cell Number and the signal of adjacent area when meeting measurement delay condition, by extending to the measurement period of adjacent area, to reduce the measurement to adjacent area Frequency extends stand-by time to reduce power consumption.

The embodiment of the invention provides a kind of method of nearby region measurement, the position letter for the wireless terminal that this method will acquire Breath is applied in the measurement process to adjacent area, to achieve the purpose that save electric energy.Referring to Fig. 8, method stream provided in this embodiment Journey includes:

801, when being in idle condition and detecting that the signal of serving cell changes, wireless terminal is to serving cell Signal and the signal of adjacent area measure.

It is identical as the realization process of above-mentioned steps 601 that this step implements process, referring specifically to above-mentioned steps 601, this Place repeats no more.

802, wireless terminal obtains location information.

When detecting the signal stabilization of serving cell, the baseband processor in wireless terminal can be sent to application processor Location information acquisition request, when receiving location information acquisition request, application processor is obtained wireless whole by modules such as GPS Current location information is held, and the location information that will acquire is sent to baseband processor, the position obtained as wireless terminal Information.

803, wireless terminal judges the letter of serving cell according to location information, the signal of the signal of serving cell and adjacent area Number and adjacent area signal whether meet measurement delay condition, if so, execute step 804, if not, execute step 805.
