Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is explicitly described, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.
Specification of the invention, claims and term " first " in above-mentioned attached drawing, " second ", " third " etc. are to be used to distinguish similar objects, without being used to describe a particular order or precedence order.It should be understood that the data used in this way are interchangeable under appropriate circumstances, so that the embodiment of the present invention described herein for example can be performed in other sequences than those illustrated or described herein.Furthermore, term " includes " and " having " and their any deformation, it is intended to cover and non-exclusive includes, such as, the process, method, system, product or equipment for containing a series of steps or units those of are not necessarily limited to be clearly listed step or unit, but may include other step or units being not clearly listed or intrinsic for these process, methods, product or equipment.
The technical solution of the embodiment of the present invention, it can be applied to the various communication systems of wireless cellular network, such as: global mobile communication (Global System of Mobile communication, abbreviation GSM) system, CDMA (Code Division Multiple Access, abbreviation CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access Wireless, abbreviation WCDMA) system, General Packet Radio Service (General Packet Radio Service, abbreviation GPRS) system, long term evolution (Long Term Evolution, abbreviation LTE) system, Universal Mobile Communication System (Universal Mobile Telecommunications System, referred to as: UMTS) etc., the embodiment of the present invention does not limit.
In a communications system, the cell for providing communication service for terminal is known as serving cell, and the cell adjacent with serving cell is known as neighboring community (referred to as: adjacent area).Cell has certain coverage area, when terminal is mobile, serving cell margin signal quality may be gradually reduced, and terminal is in order to keep continuous communication service, it needs to be reported according to the signal measurement result trigger event of serving cell and neighboring community, to be switched to the better cell of signal quality.
Whether identical according to switching front and back cell operation frequency point, switching is divided into frequency switching and alien frequencies switching；Whether identical according to switching front and back cell said system, switching is divided into homologous ray switching and the switching of different system.Wherein, alien frequencies switches, and is in call or connected state, terminal is switched to another working frequency points in the process of moving, from a working frequency points；Different system switching, it is in call or connected state, terminal is switched to another system in the process of moving, from a system, such as, the 3G network of connection is 2100 system of UMTS, and 2G network is 900 system of GSM, currently, terminal works are in 2100 system of UMTS, but when the reception dtr signal of terminal under 2100 system of UMTS, terminal is switched to 900 system of GSM, this switching is different system switching.
It should be noted that including multiple frequency points in a frequency range, it does not include the switching in same frequency range between different frequent points that the switching of alien frequencies described in the embodiment of the present invention, which is primarily referred to as switching in the alien frequencies of different frequency range,.
The switching of broad sense includes that handover measurement, handover decisions and switching execute (i.e. the switching of narrow sense) three phases.Measuring phases, terminal carries out measurement of correlation according to the measuring configuration message that base station issues, and measurement result is reported to base station.Decision phase, base station are assessed according to the measurement result that terminal reports, and decide whether triggering switching.Execution stage, base station are switched to Target cell according to the result of decision, controlling terminal, complete to switch by terminal.
In measuring phases, after alien frequencies handover measurement or different system handover measurement are triggered, sending measuring gap (GAP) relevant configuration, terminal will be started measurement gap by base station according to the configuration of base station.Measure gap just
It is that terminal is allowed to leave the period that current frequency point is measured to other frequency points, measurement gap is used for alien frequencies handover measurement and different system handover measurement.In alien frequencies handover measurement and different system handover measurement, terminal is only measured in measurement gap.
Currently, the terminal at least two antennas is to select antenna based on work at present frequency range.But when the terminal carries out alien frequencies handover measurement or different system handover measurement, it is in measurement gap, remove to receive frequency point or the signal of another system under another frequency range using the antenna with work at present frequency band match, and the antenna might not match with frequency point under another frequency range or another system, therefore, it is likely to occur the situation that measurement reports deviation larger, generates the phenomenon that switching causes call drop or network selection to cause to fall net etc. to influence user experience not in time not in time.
In view of the foregoing drawbacks, the embodiment of the present invention provides a kind of antenna switching method, device and terminal, suitable for the terminal at least two antennas.The embodiment of the present invention can avoid the terminal at least two antennas when carrying out alien frequencies switching or different system switches, and generate the phenomenon that switching causes call drop or network selection to cause to fall net etc. to influence user experience not in time not in time.
Fig. 1 is the flow chart of inventive antenna switching method embodiment one.The embodiment of the present invention provides a kind of antenna switching method, and this method can be by antenna-switching device or the terminal at least two antennas executes, wherein antenna-switching device can integrate among the above-mentioned terminal at least two antennas.As shown in Figure 1, the antenna switching method includes:
S101, determine whether terminal is executing different-frequency measure or isosystem measurement.
Wherein, since isosystem measurement (different system handover measurement i.e. above) is similar with the principle of different-frequency measure (alien frequencies handover measurement i.e. above), it is explained by taking different-frequency measure as an example here.
Specifically, the principle of different-frequency measure is as follows:
Different-frequency measure based on coverage area is triggered by terminal.Terminal leaves the coverage area of serving cell, and when reaching the coverage area of alien frequencies adjacent area, terminal, which measures serving cell signal quality, will trigger the different-frequency measure based on coverage area less than certain thresholding.
Based on the different-frequency measure of load by base station triggers.When serving cell load reaches alien frequencies load balance thresholding, base station will select a certain number of terminals to carry out different-frequency measure according to the frequency point tenability of terminal, distribution/reserved priority (Allocation and Retention Priority, referred to as: ARP) and occupancy resource situation.
When terminal is in connected state, when the signal quality of serving cell is lower than certain thresholding, base will be triggered
Station issues different-frequency measure configuration, and terminal starts to carry out different-frequency measure.When the signal quality of serving cell is higher than certain thresholding, terminal will stop different-frequency measure.
During different-frequency measure, terminal discovery neighboring cell signal quality (is determined) that report measurement results are to base station based on coverage area and the alien frequencies handoff threshold based on load by different parameters when being greater than certain thresholding.
Therefore, the antenna-switching device of the antenna switching method or the terminal at least two antennas are executed, can determine whether terminal is executing different-frequency measure or isosystem measurement.
S102, when determining that terminal is to execute different-frequency measure or when isosystem measurement, judging whether the first antenna of the terminal work at present is optimal antenna.
Wherein, above-mentioned optimal antenna is corresponding with frequency range used by different-frequency measure or isosystem measurement.
Specifically, terminal starts different-frequency measure or isosystem measurement used antenna before, is herein referred to as " first antenna ".
The first antenna is before terminal starts different-frequency measure or isosystem measurement, works in antenna under working frequency points used in terminal.Since measurement gap is that terminal is allowed to leave the period that current frequency point is measured to other frequency points, therefore, before terminal starting different-frequency measure or isosystem measurement and later, used working frequency points are different, to which first antenna is not necessarily the optimal antenna corresponding to frequency range used by different-frequency measure or isosystem measurement.Therefore it executes the step and is judged.
If S103, first antenna are not optimal antennas, the work antenna of terminal is switched to optimal antenna.
In the step, the work antenna of terminal is switched to the execution of optimal antenna, the prior art can be referred to, it will not go into details for the embodiment of the present invention.
The present embodiment is determining terminal execution different-frequency measure or isosystem measurement, and when currently employed first antenna is not optimal antenna, the work antenna of the terminal is switched to optimal antenna, the optimal antenna is corresponding with frequency range used by different-frequency measure or isosystem measurement, to guarantee have at least two antennas terminal (such as, multiple antennas mobile phone) when executing alien frequencies switching or different system switches, measurement, which reports, can accurately reflect actual conditions, it avoids generating phenomena such as switching causes call drop or network selection to lead to fall net not in time not in time, promote the communication performance and user experience of terminal.
It on the basis of the above embodiments, can be in S102, judging whether the first antenna of terminal work at present is optimal antenna specifically: obtain the first operating mode and the first working frequency range of terminal；Presetting database is searched, first operating mode is read and the corresponding antenna of the first working frequency range is the second antenna；If first antenna is identical as the second antenna, determine that first antenna is optimal antenna.Alternatively, determining that first antenna is not optimal antenna if first antenna is different from the second antenna.Wherein, presetting database may include

Wherein, for the mode of the first operating mode (and second operating mode hereinafter) of acquisition terminal, the present invention is not limited.Here, only it is illustrated.
In a kind of implementation, firstly, terminal judges whether terminal itself is on call；If terminal is on call, then judges whether terminal is inserted with earphone or in hands-free state；If terminal is not inserted with earphone, not also in hands-free state, whether the posture for further judging that user holds the terminal is left head fingerprint formula；If the posture that user holds the terminal is left head fingerprint formula, it is determined that the first operating mode is left head fingerprint formula, if the posture that user holds the terminal is not left head fingerprint formula, it is determined that the first operating mode is right head fingerprint formula.
In another implementation, firstly, terminal judges whether terminal itself is on call；If terminal is on call, then judges whether terminal is inserted with earphone or in hands-free state；If terminal is inserted with earphone, or, being in hands-free state, whether the posture for further judging that user holds the terminal is left hand-held mode；If the posture that user holds the terminal is left hand-held mode, it is determined that the first operating mode is left hand-held mode, if the posture that user holds the terminal is not left hand-held mode, it is determined that the first operating mode is the right side

After alien frequencies switching or the switching of different system are completed, terminal works are in the first working frequency range, and known terminal has obtained first working frequency range through the foregoing embodiment, therefore, acquisition are not repeated herein.In addition, due to the operating mode of terminal be it is variable at any time, the embodiment will also obtain the second operating mode of terminal, second operating mode can be with the first operating mode in above-described embodiment it is identical, be also possible to it is different, the embodiment of the present invention not limit.
It should be noted that determining that the work antenna after switching may include: to determine the work antenna after switching according to each antenna received signal quality of terminal or transmission power.Specifically, it is assumed that there are two antennas for terminal tool: antenna 1 and antenna 2.When the terminal works are when the first working frequency range, its work antenna may be antenna 1, it is also likely to be antenna 2, work antenna after the switching is specifically judged by terminal according to the two antenna received signal quality or transmission power, wherein, the antenna that received signal quality is good or transmission power is big is the work antenna after switching.
S203, presetting database is searched, reads the first working frequency range and the corresponding antenna of the second operating mode is third antenna.
Wherein, the second operating mode is one kind of operating mode.
If S204, switching after work antenna it is different from third antenna, by it is in presetting database,
