Embodiment
Design of the present invention is, portable terminal is according to the current Business Entity request quantity of initiating simultaneously of user, for every kind of service dynamic is distributed virtual AT command logic passage, set up logical channel with the target protocol stack of AT order or the mapping relations of target protocol stack business interface, to distinguish according to described mapping relations be the execution result of which kind of business to portable terminal when the target protocol stack was handled corresponding service and returned response command.
The present invention cooperates by the function of software inhouse, reaches the concurrent service handling process in user level, uses much channel communication, sets up a plurality of logical channels on sending and receiving, the passage of every kind of professional correspondence oneself.
Claim among the present invention to realize that the entity of the method for the invention is ATI (AT interface) module (hereinafter to be referred as ATI), it is finished AT and orders management of multichannel distribution, establishment and mapping relations etc., it on provide unified and the simple user interface, to descending directly to communicate by letter with the target protocol stack.The ATI module in the cell phone software platform the position and form schematic diagram as shown in Figure 1, the ATI module links to each other with telephone service API TAPI to last, TAPI is the upper-layer user of ATI here, directly calls the interface of ATI; The ATI module is to linking to each other with protocol stack (modem) down.The ATI module comprises two parts: multichannel management unit and map unit.The software system architecture of ATI module comprises input, output queue as shown in Figure 2, several main submodules such as task engine and channel map, collaborative dynamic creation and the mapping of finishing the AT passage of these submodules.
Below in conjunction with drawings and Examples technical scheme of the present invention is described in further detail.
Embodiment
Under the situation that does not change current system configuration and protocol interface parameter, the AT of present embodiment order multichannel management mechanism is that the form with a kind of system task exists on the software level, can guarantee that like this upper-layer user initiates the relevant voice and packet data concurrent service of multiplex telephony simultaneously, and can shield the realization difference with adaptive all types of target protocol stack.
In the present embodiment, realize that the method for mobile terminal parallel Business Processing specifically comprises following step:
Step 1, interface (the telephone service API TAPI in the corresponding diagram 1) request of calling ATI sends certain professional corresponding AT order, the ATI module is according to the corresponding AT logical channel of type of service application (the following passage that abbreviates as) of user's request, described passage identifies with passage ID (sign) number, set up logical channel with the target protocol stack of AT order or the mapping relations of target protocol stack business interface, the passage application successfully is that portable terminal distributes passage success back ATI module that certain channel status is set;
If the application passage is unsuccessful, the ATI module is notified the user failure cause by function return value, and the continuation application passage, up to applying for successfully.Described channel status content comprises AT command id number (command ID) corresponding on prepass, the action type of AT order (carry out, read, be provided with and test etc.), residing pattern (order or data pattern) and calling entity sign (at CC (Call Control calls out control, abbreviation CC) when there is the multiway calling entity in module) etc.It is in order to preserve the current AT order relevant parameter that sends, when receiving the result (such as OK) that protocol stack (modem) returns, just to distinguish the result of the request execution that is which kind of professional correspondence like this that channel status is set.The intact back of Business Processing ATI can discharge and close corresponding passage.
Step 2, this step is referring to Fig. 2, when AT passage application success, and begin to send when ordering, ATI at first puts into an overall input rank to the AT order, and this formation is a FIFO (FirstIn First Out, first-in first-out) and the formation that has priority, the benefit of doing like this is the pressure that the request of cache user brings system and protocol stack resource on the one hand, is that the AT order of guaranteeing high priority is handled timely and responded on the other hand;
What deserves to be explained is that the difference of the formation of input rank of the present invention and prior art is to have added the passage element in formation, by the binding of formation node realization AT order and channel number.The output queue that the back will be mentioned does not need priority.
Step 3, the task engine cyclic query of ATI and the whole input rank of scanning, take out the highest AT command string of priority from the input rank top, the state of evaluating objects protocol stack then, if the interface of target protocol stack or target protocol stack (being the modem module among Fig. 1 herein) is only supported the single physical serial ports, the passage ID of affix correspondence in the order that sends then, if the interface of target protocol stack or target protocol stack connects a plurality of serial ports, then only need directly the AT order to be dealt on the serial ports of appointment according to corresponding passage-serial ports mapping table; Also having a kind of situation is that the target protocol stack that the AT order is mail to does not provide the AT interface, but message interface, at this moment just order directly can not be dealt into serial ports and get on, but will be dealt into the target protocol stack again through encoding and decoding and the passage ID and the service identification index mapping process of AT order;
This step is to realize the critical process of AT multichannel communication.A lot of modules of software platform all are to move (being subjected to the unified scheduling and the management of operating system) with the form of a task in the present embodiment, and therefore, the task engine here refers in particular to the processing procedure that cell phone platform operating system is called a subtask entrance function.The state of the stack of target protocol described in this step refers to support single serial ports (com) still multiplexed (MUX), and current order (command) attitude that is in still is data (data) attitudes.Passage-serial ports mapping table is disposed according to channel resource and serial port resource by ATI, and its content comprises channel number, the string slogan of channel number correspondence, and service identification, as shown in Figure 2.
Step 4, the process of the AT order that ATI reception protocol stack returns is just in time opposite, at first according to the mapping relations of passage ID with the serial ports that receives order, task engine receives corresponding data from serial ports, put into the output queue of an overall situation then equally, the priority of every order in this formation and passage ID and input rank are one to one, and the user fetches the AT order data of wanting according to the passage ID that sends the AT order;
The AT order that protocol stack returns reports ATI by virtual serial port, ATI finds corresponding passage ID number according to the passage-serial ports mapping relations of having preserved, then according to the channel status mapping table, which professional corresponding order parsing is, by a call back function interface interchange, passage ID and order data are returned to the user simultaneously at last.
Fig. 3 is a control flow chart of supporting the multichannel AT order of user concurrent business, and as shown in the figure, beginning most is startup work main task; Be to finish corresponding multichannel initialization task (comprise the initialization of formation, send, receive the startup of workflow, multichannel enable or the like) then; Next, the ATI module enters the idle waiting state, it otherwise the event notice of various users of the monitoring that stops and protocol stack, comprise mainly that wherein the upper-layer user sends the request of AT order, the message that the target protocol stack reports through passage mapping and order encoding and decoding, and the message that directly reports by serial ports etc.
Ask to send AT when order the user, if the ATI module supports multichannel to send, the priority of order is the highest, and the channel status of application is not IDLE, then can directly be dealt into the purpose protocol stack, and all the other situations then need to put into earlier does buffer memory in the input rank.
In the present embodiment, software flow when multichannel sends the AT order as shown in Figure 4, after transmission flow starts, the querying command input rank that task engine does not just stop, in case formation is not empty, and the corresponding AT channel status of order becomes IDLE, just the target protocol stack is mail in first order of current queue, and corresponding channel status is set, in the process that down sends, also will distinguish different situations respectively, be through command messages mapping invocation protocol stack interface, still is dealt in the protocol stack by single serial ports or MUX multichannel serial.
In the present embodiment, software flow when multichannel receives the AT order as shown in Figure 5, it is the inverse process of process of transmitting, and the ATI module is put the AT order data of receiving in the corresponding output queue into according to the mapping relations of serial ports and passage, and resets corresponding channel status.
In the present embodiment, realize that the method for mobile terminal parallel Business Processing is used on the cell phone platform, but this method adopts the AT order also can use by in virtual serial port and the system that protocol stack is communicated by letter at PC (PC) side or other.
Should be understood that; concerning the those of ordinary skill in field, the technology of the present invention place; can be equal to accordingly according to technical scheme of the present invention and design thereof and change or replace, and all these changes or replacement, all should belong to the protection range of claims of the present invention.
