Specific embodiment
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
The communication terminal (such as mobile phone) that the prior art is related to first by normal mode enter the process of calibration mode into
Row is simple to be introduced.
In the prior art, if desired the communication terminal under normal mode is calibrated, is typically necessary advanced
The operation re-powered after the lower electricity of row, then could select to enter calibration mode.As known to those skilled in the art, communication terminal
After normal mode refers to communication terminal normal boot-strap, it is able to carry out the operation for the operations such as make a phone call, send short messages, surfing the Internet, downloading
System model.
As shown in Figure 1, it includes following below scheme that communication terminal, which enters calibration mode by normal mode, in the prior art:
Firstly, executing step S101, communication terminal is in normal mode.
When needing to calibrate communication terminal, S102 is thened follow the steps, communication terminal carries out down electrically operated.
After step S102, step S103 is executed, communication terminal carries out power on operation.
After communication terminal completes power on operation, step S104 is executed, communication terminal sends power on operation to control equipment
Completed handshake information.
As known to those skilled in the art, the control equipment refers to that control communication terminal is calibrated in the calibration mode
The equipment of operation, usually can be real by being equipped with the PC (PC, Personal Computer) of respective alignment tool
It is existing.
After issuing the handshake information, step S105 is executed, equipment to be controlled is waited to select to communication terminal sending mode
Message.Model selection in step S105 refers to model selection of the communication terminal conducted in start process, usual situation
Lower booting default enters normal mode, in particular demands, can be selected to enter calibration mode by the control equipment.
During waiting equipment to be controlled to send message to communication terminal, also execution step S106 judges whether to receive
To the message of model selection, and whether overtime wait.
In the case where not receiving the message of model selection, is had not timed out if waiting, step S105 is continued to execute, if waiting
To time-out, then time-out is waited, then follow the steps S107, closes the switch of control model selection.After step S107, communication terminal will
Into normal mode；If receiving the message of model selection, and wait and having not timed out, then follow the steps S108, communication terminal enters
Calibration mode.
It follows that communication terminal by normal mode enters calibration mode in the prior art, require to communication terminal into
It is capable to restart and (descend electricity to power on again, model selection), and present inventor recognizes: when the communication terminal for needing to be implemented calibration operation
Negligible amounts when, those skilled in the art can't usually perceive the side that the prior art is entered calibration mode by normal mode
Formula there are what deficiency, and when needed to be implemented on production line the quantity of communication terminal of calibration operation it is especially huge when, existing skill
Art it is lower electricity, re-power by way of calibration mode, not only shut down, the operation turned back on itself needs to occupy centainly
Time, and after lower electricity powers on again, the re-enumeration of the interface software driving of communication terminal is also required to the time, in addition, opening again
It also needs for the associated process of operating system to be loaded into memory during machine, it is contemplated that above-mentioned factor, cumbersome and waste
The shortcomings that time, waste of manpower resource, just displays.
Present inventor further analyzes: the difference between the normal mode and calibration mode of communication terminal, substantially
It can be presented as the situation that opens or closes of corresponding module in the communication protocol stack (PS, Protocol Stack) of communication terminal
It is different.The communication protocol stack includes multiple protocol stack modules (module referred to as in protocol stack), and the items of communication terminal are logical
The realization of communication service needs to load corresponding protocol stack module in an operating system and is just able to achieve.In the normal mode, Ge Xiangtong
Telecommunication function needs to load at this time the modules in the communication protocol stack, i.e., under normal mode generally all in open state
Modules in communication protocol stack are in the open state；And in the calibration mode, usually for a certain communication service (such as
Radio frequency) it is calibrated, if other communication services are also being run at this time, it is likely that generated to the calibration result of this communication service
Interference, for exclusive PCR, need to separate the respective protocol stack module of other communication services from operating system, only retain with
The relevant protocol stack module of calibration tasks, i.e., module relevant to calibration tasks is in unlatching in communication protocol stack under calibration mode
State, other modules unrelated with calibration tasks are in close state.However, when communication terminal is under normal mode, according to
The unlatching of corresponding module and the closing of independent modules in different calibration tasks control communication protocol stacks, this is not light and easy
It lifts, but needs to make corresponding improvement to the calling control of communication protocol stack, be a relatively complicated task, therefore general
It is not easy to be expected by those skilled in the art.
Based on above-mentioned analysis, in one embodiment of the invention, the side that a kind of communication terminal enters calibration mode is provided
Method, comprising: when communication terminal is in normal mode, by making it into calibration to the first control command of communication terminal transmission
Mode；First control command is suitable in the case where the communication terminal maintains power-up state always, triggers for described
In the communication protocol stack of communication terminal module relevant to pending calibration tasks unlatching control, and with pending school
The closing of the unrelated module of quasi- task controls.
In the specific implementation, the process that communication terminal enters calibration mode by normal mode in the present embodiment is as shown in Figure 2:
Step S201, communication terminal are in normal mode.
Step S202, communication terminal maintain power-up state always.
Step S203, it is ensured that the port communicated between communication terminal and control equipment is in the open state.This implementation
In example, the control equipment is the equipment for carrying out calibration operation in the calibration mode suitable for controlling communication terminal, specifically with installation
There is the PC of respective alignment tool to realize.
Step S204, control equipment send the first control command to communication terminal by the port, and triggering is for communicating eventually
In the communication protocol stack at end module relevant to pending calibration tasks unlatching control, and with pending calibration tasks
The closing of unrelated module controls.
Step S205, communication terminal enter calibration mode.
The communication terminal provided through this embodiment enters the method for calibration mode, in the normal mode without restarting (packet
Containing lower electricity power on operation, mode selecting operation etc. again) communication terminal, can make as long as sending a control command its quickly into
Enter calibration mode.
In actual implementation, first control command can be realized by way of AT order or DIAG order.This reality
It applies in example, is illustrated so that first control command is AT order as an example.
As known to those skilled in the art, the mode communicated between domestic and international more mature PC and mobile phone mostly uses greatly
Following two: DIAG order and AT order.
AT, that is, Attention, AT Command Set are set from terminal device (TE, Terminal Equipment) or data terminal
Standby (DTE, Data Terminal Equipment) is whole to terminal adapter (TA, Terminal Adapter) or data circuit
What end equipment (DCE, Data Circuit Terminal Equipment) was sent.By TA, TE sends AT order and moves to control
The function of dynamic platform (MS, Mobile Station), interacts with wireless cellular network business.User can by AT order into
The control of row calling, short message, phone directory, data service, fax etc..
DIAG original meaning Diagnostic is vedio on radio binary operation environment (BREW, the Binary Runtime of high pass
Environment for Wireless) platform a module, it provides test, debugging etc. for communication terminals such as such as mobile phones
Function.On binary runtime environment for wireless, AT and DIAG both of which are usually mutual exclusion, i.e., when mobile phone is under AT mode, can only respond
AT order cannot respond DIAG order, and under DIAG mode, DIAG order can only be responded, AT order cannot be responded.
Currently, " AP+CP " scheme is prevailing with the rise of intelligent communications terminal (such as smart phone) in the communications field,
Wherein AP (Application Processor) is properly termed as application processor, is responsible for the processing of all application programs, CP
(Communication Processor) is properly termed as Communication processor, is responsible for the execution of all communication softwares.The part AP and CP
Part be it is separated from each other, generally communicated between the two by AT order, such as: when making a phone call, AP passes through AT order
When controlling CP, and having incoming call, CP notifies AP by AT order.In the present embodiment, the communication terminal is to have " AP+CP " framework
Smart phone for be illustrated.
It should be noted that the first control command in the present embodiment is not the AT that those skilled in the art generally use
Order, but the AT order with specific function, are to realize that communication terminal provided in this embodiment enters calibration mode
Method and especially set up, which will be added in communication protocol stack, once identify the AT order, just trigger for
In the communication protocol stack of communication terminal module relevant to pending calibration tasks unlatching control, and with pending school
The closing of the unrelated module of quasi- task controls.
In the specific implementation, the calibration tasks can be in different wireless access technology (RAT, Radio Access
Technology it is carried out under), the wireless access technology includes: global system for mobile communications (GSM, Globe System of
Mobile Communication), TD SDMA (TD-SCDMA, Time Division-Synchronous
Code Division Multiple Access), wideband code division multiple access (WCDMA, Wideband Code Division
Multiple Access), long term evolution (LTE, Long Term Evolution) etc.；Under every kind of wireless access technology, all
It may include a plurality of types of calibration tasks such as RF calibration, the calibration of power, signal gain calibration and temperature correction.
Therefore, if the current pending calibration tasks of communication terminal are the RF calibration under GSM, the communication of communication terminal
Module relevant with pending calibration tasks then should belong in protocol stack module relevant to gsm communication mode in protocol stack,
And in the communication protocol stack protocol stack module relevant to the communication patterns such as TD-SCDMA, WCDMA or LTE then should belong to
The unrelated module of pending calibration tasks, protocol stack module relevant to radio frequency should belong to and pending calibration tasks phase
The module unrelated with pending calibration tasks should belong in the module of pass, the protocol stack module unrelated with radio frequency.In this implementation
In example, according to the difference of pending calibration tasks, by the communication protocol stack of communication terminal with pending calibration tasks phase
The module of pass is opened, and the module unrelated with pending calibration tasks is closed, just can make communication terminal into
Enter calibration mode.
In the present embodiment, Xiang Suoshu communication terminal sends the first control command and makes it into calibration mode, can specifically lead to
Under type such as is crossed to realize:
After receiving first control command, the communication terminal is made to enter offline mode；In the offline mode
Under, the modules in the communication protocol stack are in closed state；
Module relevant to pending calibration tasks in the communication protocol stack is opened, so that the communication terminal enters
Calibration mode.
In actual implementation, so that the communication terminal is entered offline mode is locally to force to carry out in the communication terminal
's.It should be noted that can generally be sent to network side when communication terminal enters offline mode in the normal fashion in the prior art
Space interface signaling, to notify the network side communication terminal to will be switched off the connection with communication network；And in the present embodiment, the communication is eventually
End is locally to be forced into offline mode, can't send space interface signaling to network side, so can more quickly make described
Modules in communication protocol stack enter closed state, to quickly communication terminal be made to be switched to calibration mode.At other
In embodiment, after Xiang Suoshu communication terminal sends the first control command, it is not absolutely required to by each mould in communication protocol stack
Block is all closed, and is then turned on module relevant to pending calibration tasks, and directly in communication close protocol stack with it is pending
The unrelated module of calibration tasks, keep module relevant to pending calibration tasks in communication protocol stack to be in opening state
State.
In actual implementation, calibration operation is carried out in the calibration mode since control equipment controls the communication terminal, is led to
It is all often to be transmitted in the form of DIAG order, and the communication terminal is typically all in the form of AT order in the normal mode
Relevant operation is carried out, is generally also carried out by AT order between the application processor and Communication processor in the communication terminal
Communication, it is highly efficient for the transmission of DIAG order and identification under calibration mode in order to make, it can pass through and calibration marker is set
The command id transmitted between the control equipment and the communication terminal is AT life by the mode of (calibration flag)
Order or DIAG order.
In the present embodiment, when the communication terminal enters calibration mode, the calibration marker, which can be set, to be controlled
The command id transmitted between equipment and communication terminal is DIAG order.In actual implementation, if the calibration marker is arranged
It is 1, then controls the order transmitted between equipment and communication terminal and be generally all identified as DIAG order, if the calibration marker is set
It is set to 0, then controls the order transmitted between equipment and communication terminal and is generally all identified as AT order.
In the specific implementation, transmission used interface can be ordered between the control equipment and the communication terminal
Two threads are set up in corresponding process, are respectively used to the transmission of AT order Yu DIAG order, realize two according to the calibration marker
Switching between a thread.
It should be readily apparent to one skilled in the art that " transmission order is made between control equipment and communication terminal in the present embodiment
With interface " in " interface ", be not limited solely to hardware view, what is more embodied is the meaning of software view, control equipment and logical
Letter terminal, which passes through, is somebody's turn to do " interface " transmission order, needs respective drive program to be just able to achieve, specifically then relies on and be somebody's turn to do " interface "
Accordingly " process " handles data communication between the control equipment and the communication terminal, is somebody's turn to do " process " in the present embodiment and is contained in
The application processor of communication terminal, in actual implementation usually with " Engpc " name, can be understood as be control equipment with
The channel of order transmission is realized between communication terminal, the calibration marker is set in " Engpc " this process, and is respectively used to
AT order transmission then switches according to calibration marker progress is corresponding to two threads that DIAG order is transmitted, logically can be with
It is interpreted as the switching of the transmission channel between control equipment and communication terminal, if the calibration marker is set as 1, the life transmitted
Enable the channel DIAG, if the calibration marker is set as 0, the channel AT is walked in the order transmitted.By the above-mentioned means, can make to control
DIAG transmission channel and AT transmission channel are supported between control equipment and communication terminal simultaneously.
Certainly, in other embodiments, it can not also use above by two threads and set up the side of calibration marker
Formula realizes the identification and processing that order is transmitted between control equipment and communication terminal.Such as: can by will control equipment with
The order transmitted between communication terminal is packaged in the form of DIAG frame, judges the control equipment by detection DIAG frame
The order transmitted between the communication terminal be in the form of DIAG frame to the DIAG order that is formed after AT order encapsulation or
Pure DIAG order；When communication terminal is under normal mode, controlling the order transmitted between equipment and communication terminal is with DIAG
The DIAG order that is formed after the form of frame encapsulates AT order, realization be still original AT order function；And when described logical
Letter terminal enters calibration mode, and controlling the order transmitted between equipment and communication terminal is pure DIAG order.It should be noted that
In these cases, first control command should also be as being to order the DIAG formed after AT order encapsulation in the form of DIAG frame
It enables.
In actual implementation, first control command can be transmitted by UART or USB interface.It needs to illustrate
It is that the UART or USB interface in the embodiment of the present invention are the concept of software view, same physics is used in actual implementation and is connect
Mouthful, only the driver on the basis of the physical interface is different, so as to cause the area between UART interface and USB interface
Not.
In the present embodiment, the interface specifically uses UART interface, can so make to control between equipment and communication terminal
It is more stable when transmission order.In other embodiments, the interface can also use USB interface, for the technology of the present invention side
The realization of case can't impact.
It should be pointed out that due to UART interface or USB interface be all in communication terminal it is more common, so not needing
In addition it creates new interface control equipment is connected with communication terminal to realize the transmission of control command or data.
This gives the methods that communication terminal is quickly switched into calibration mode from normal mode, when communication terminal exists
It, both can be by lower electricity in the prior art again if wishing to return to normal mode after completing all calibration tasks under calibration mode
The mode powered on enters normal mode after restarting, and the method that can also be provided by following example exits calibration mode to enter
Normal mode.
In another embodiment of the present invention, a kind of method that communication terminal exits calibration mode is also provided, comprising: when
Communication terminal is in calibration mode, by the communication terminal send the second control command make its exit the calibration mode with
Into normal mode；Second control command is suitable in the case where the communication terminal maintains power-up state always, triggering
Unlatching control for modules in the communication protocol stack of the communication terminal.
It should be noted that the communication terminal in the present embodiment has been in the state of calibration mode, as communication end
How end enters calibration mode, this is realized after can both restarting in such a way that lower electricity in the prior art powers on again, can also lead to
Cross the method realization that communication terminal given by one embodiment enters calibration mode.In the present embodiment, " in a upper reality
It applies the communication terminal that example provides to enter on the basis of the method for calibration mode, implements the method that communication terminal exits calibration mode "
For be illustrated, related content can be repeated no more with reference to the description in upper one embodiment.
In the normal mode due to communication terminal, usually every communication function needs to load at this time all in open state
Modules in the communication protocol stack, therefore can be from control equipment by sending a control command to communication terminal
