Particularly, when the sum of antenna in terminal is three groups, the N selects 1 switch selection circuit to include one, and N= 2；The N selects the side with two interfaces of 1 switch selection circuit to be connected with two variable antennas, has the one of an interface Side selects 2 one of interface of switch selection circuit B sides to be connected with 2, and fixed antenna then directly selects 2 switch to select electricity with 2 Another interface of road B sides is connected.Fig. 7 is refer to, Fig. 7 is shown when it is 3 that antenna, which always organizes number, the arrangement of antenna gating circuit Schematic diagram.

In S401, when meeting antenna switching condition, work when BBP poll each group antenna is in running order Make state parameter.Antenna switching condition refers to the condition that triggering current antenna switches over, and it is specifically included：Own in terminal Two groups of antennas for work are selected in antenna, and primary antenna and auxiliary antenna are determined from this two groups of antennas；Specifically, choosing Two groups of antennas for being used for work are selected out, one of which necessarily fixed antenna, remaining one group is then selected from other variable antennas, As target antenna.Then, based on fixed antenna and target antenna, target primary antenna and the auxiliary antenna of target are redefined.

Specifically, antenna switching condition, in the present embodiment, can include：The work of current primary antenna and/or auxiliary antenna State parameter is less than corresponding threshold value；Or, the working status parameter of current primary antenna and/or auxiliary antenna is in preset time Deterioration amount is more than corresponding change threshold.That is, for antenna switching condition, it is broadly divided into two types, one It is that the occurrence of the working status parameter of antenna is less than corresponding threshold value.Here threshold value, which typically refers to terminal, normally to be entered Row communication, will not cause excessive power consumption, also without the hard defects in real experiences in user's communication process.In other words, threshold value Embody tolerance level of the user to terminal.Typically, user can be too fast to terminal power down, and network connection is not smooth, breaks during call Shi Xu does not feel well, and these can cause bad user experience, is all probably the work of certain antenna under current operating state State parameter is too low to be caused., can also be specific and whether working status parameter can trigger antenna switching condition after being less than threshold value Including being using any group antenna under working condition as reference.Working condition is next to share two groups of antennas, is primary antenna and auxiliary day respectively Line, when carrying out the comparison of threshold value, can only with reference to any one group of antenna in primary antenna and auxiliary antenna, any one group of antenna Working status parameter is considered as less than threshold value meets antenna switching condition, or with reference to two groups of antennas, only two groups of days The working status parameter of line is below threshold value and is just considered as to meet antenna switching condition.It is noted that the work shape of antenna State parameter is various, is typically also different with reference to threshold value used by different working status parameters；Terminal institute The state at place is different, and the demand of working status parameter is also not quite similar, such as, when terminal is in idle state, do not make Demand, now just It is not necessary to pursue too high working status parameter, threshold value now can be with lower slightly, and works as end When use state, for example converse, surf the Net, then keep good communication quality then necessary, door now Limit value can ensure that the communication quality of terminal is constantly in a higher level with slightly higher.Further, since primary antenna and auxiliary antenna Working condition differ, the requirement for working status parameter between the two is not necessarily consistent, such as main day The working status parameter requirement of line should be higher than auxiliary antenna, that is to say, that for the working status parameter of primary antenna and auxiliary antenna It is it can also be provided that different.

Second, it is that the working status parameter of current primary antenna and/auxiliary antenna drastically deteriorates in preset time.Deteriorate also just Be that working status parameter becomes worse, and drastically deteriorate, it is most possible the reason for be probably the gripping of user under working condition Antenna cause and block, this can cause the working status parameter of corresponding antenna to become far short of what is expected in a short time, in this feelings Under condition, even if the working status parameter of primary antenna and auxiliary antenna can also be considered as still above threshold value and meet antenna switching Condition.Accordingly, because the working status parameter type of antenna is different, its corresponding preset time and change threshold can not Together；Terminal state in which is different, and its corresponding preset time and change threshold can also be different；Due to primary antenna and auxiliary antenna Working condition differ, the requirement for working status parameter between the two is also not necessarily consistent, corresponding default Time and change threshold can also be different.

In addition, in the present embodiment, in order to keep the stability of terminal, the frequency of switching antenna is reduced within the bounds of possibility Rate, when judging whether to meet antenna switching condition, can also repeated detection within a certain period of time, according to the result of repeated detection Determine whether the switching of progress antenna；Such as if finding first, the working status parameter of primary antenna is less than threshold value, and in 1s Interior, the working status parameter of primary antenna has been returned to more than threshold value, then repeatedly judges that can avoids switching off primary antenna The embarrassment that switchback once again comes again afterwards.Or can also be by certain guard time being set after the handover, to avoid Antenna is switched again, such as, after the antenna of terminal is passing through once switching, it is arranged in 5s once again to switch, can Effectively to prevent the generation of ping-pong.

Specifically, working status parameter when BBP poll each group antenna is in running order can include：Base In provided with processor antenna switching control module adjustment N select 1 switch selection circuit and/or 2 select 2 switch selection circuit, will Each group antenna successively with main transmitting-receiving communication；Obtained by the diagnostic service module in BBP or radio-frequency driven module Working status parameter when each group antenna is in running order.When carrying out the poll of working status parameter of each antenna, first Under ensureing that detected antenna need are in running order, that is, it is logical as the main transceiver channel of antenna access or auxiliary reception Road.Because auxiliary receiving channel only has the function of reception signal, therefore each antenna typically accesses main transceiver channel in poll, can be with Ensure the proper communication of terminal.After access, it is possible to pass through diagnostic service module (diag) or radio-frequency driven module (RF) working status parameter of the antenna of access is obtained.Working status parameter in the present embodiment, can include up parameter With the major class of downstream parameter two, wherein, up parameter is relevant with the up channel of terminal, its main reference index can include eventually The size of the transmission power at end, or, the up ratio for reaching maximum transmission power within the unit interval.Wherein, transmission power It is bigger, show that the communication quality of upward signal is poorer, because communication quality difference just needs bigger transmission power to ensure to communicate； Likewise, in the unit interval it is up reach maximum transmission power ratio it is bigger, also illustrate that the communication quality of upward signal is poorer. Downstream parameter is then relevant with the down channel of terminal, and it can mainly include signal intensity, signal quality etc. parameter.Specifically , according to the difference of network formats, such as GSM nets, WCDMA/TD-SCDMA nets, and FDD-LTE/TDD-LTE nets, it is specifically joined The signal intensity and signal quality examined are also otherwise varied.

Diagnostic service module or radio-frequency driven module are a parts in BBP, and it can be with real-time collecting The working status parameter of each antenna under working condition, for example the information such as received signal strength, transmission power and generate daily record (log).When carrying out the poll of working status parameter of antenna, using appointing in diagnostic service module or radio-frequency driven module Meaning one obtains the working status parameter of corresponding antenna.According to different network formats, diagnostic service module or penetrate The frequency of frequency drive module collection work state parameter is otherwise varied, for example TD-SCDMA acquisition interval is usually 40ms, and LTE is then 320ms.

In S402, the working status parameter of the same type of each group variable antenna is compared, determines target antenna.Compare each group The working status parameter of the same type of variable antenna, just it is to determine in each group variable antenna, the process of communication quality relation, this The purpose that antenna switches in embodiment is exactly the communication for finding the more preferable antenna of communication quality as work antenna, wherein primary antenna Quality should be best in all antennas.Target antenna is that working status parameter is best in all variable antennas, wherein it is determined that The target antenna gone out is as one of work antenna that will switch, it may be possible to primary antenna, it is also possible to auxiliary antenna.

In S403, the working status parameter of the same type of target antenna and fixed antenna is compared, and generates comparison result. Comparison for the working status parameter of the same type of each group antenna, it is clear that should be ensured that the working condition ginseng in same type It is compared between number, different types of working status parameter is usually what can not be compared；Specifically, when comparing, each group Variable antenna only can be compared with regard to a kind of working status parameter, can also be compared with reference to a variety of working status parameters, A variety of working status parameters can be only with reference to the working status parameter of up channel, or the working condition only with reference to down channel Parameter, or the working status parameter of comprehensive consideration up-downgoing channel, these embodiments are feasible in the present embodiment.
