Operation system of the present invention is meant other computer software that uses native system, as financial management system, attendance checking system or the like, and the software and hardware system of Business Processing in may moving by short message equipment or ISP.The adaptive passage of described ISP is meant and is used for by after the system loads of the present invention, can call transmission that messaging service provider (ISP) provided and the interface that receives service, also is the module that the ability that receives and send SMS message is provided for operation system.This module can be dispatched by described channel manager to be loaded and call that short message that messaging service provider (ISP) provided sends and receiving interface is worked out in advance.The adaptive passage expansion interface of described ISP (it is included in adaptive passage of IPS or the note device channels) is meant can be by the defined standard extension interface of the employed channel module of the inventive method (as the adaptive passage of the ISP of indication among Fig. 1) for third party or ISP side are developed.Utilize this standard extension interface, either party ISP can be managed and be dispatched by described channel manager by adding the adaptive passage of short message after the transmitting-receiving interface (extended instruction) of short message is provided.

Method of the present invention uses the adaptive passage expansion interface of ISP to improve the autgmentability of passage, and ISP directly for operation system provides the short message interaction capabilities, has reduced the degree of dependence of operation system to a certain third party ISP based on software of the present invention.

Described channel manager to the adaptation method of short message passage is:

The self-described interface ISMSChannelInfo that passage is set describes the relevant information and the ability of passage.

When several passage, press following selection algorithm:

Sending grouped short message: selecting earlier has the passage of mass-sending function, if do not have, then selects the passage that the single-shot function is only arranged for use, and circulation is sent short message to different objects;

Single-shot message: preferentially select the passage that the single-shot function is only arranged for use,, then select the passage of mass-sending function for use if do not have;

Transmission can be replied message: but select the passage that single-shot and replying short message are only arranged earlier for use, if do not have, then select the passage of mass-sending function for use;

Whether can send this phone number: determine whether this short message channel can send the phone number of appointment.

The example of the adaptive passage expansion interface definition of described ISP is as follows:

1. channel interface ISMSChannel

1) startup of subchannel

boolean?start(ISMSListener?listener)

2) subchannel stops

boolean?stop()

3) obtain concrete transmission class according to short message type, this smsMsgType is from the msgType attribute field of SMS

ISMSSender?getSmsSender(int?smsMsgType)

4) obtain passage and describe class

ISMSChannelInfo?getChannelInfo()。

It is as follows that described passage sends class interface ISMSSender definition example:

1) send concrete SMS message, return the purpose phone number tabulation that sends failure:

String[]send(SMS?msg)

Described SMS classes of messages has following attribute:

String msgContent: message content

String[] terminals: receive the purpose phone number tabulation of this message

String msgId: message Id

String associateAccount: relevant account number is used for up note is carried out route

String bizName: Business Name

Int sequenceeNo: the message serial number, but for answer short message, when replying, the other side is with this serial number, thus find the source message of concrete correspondence.

The self-described definition of described adaptation method of the present invention by channel capacity can guarantee to carry out suitable scheduling under the situation of the service of the different abilities that ISP provides, and provides sending and receiving short messages performance support preferably to operation system.

The self-described definition of described passage is exemplified as:

Passage is described interface: ISMSChannelInfo:

1) whether can mass-send

boolean?isGroupSend()；

2) whether can receive

boolean?isReceive()；

3) whether can send out

boolean?isSend()；

4) judge whether to send such address

boolean?canSent(String?address)；

5) obtain passage version number

String?getVersion()；

6) obtain the passage author

String?getAuthor()；

7) obtain tunnel name

String?getName()；

8) obtain the self-described information of passage

String?getDescription()。

Wherein, the description of passage definition 1), 2) and 3) load when sorting and will be called at passage, concrete ordering rule is explained as follows: can only send out and can not receive when passage, be that isReceive () definition return value is a fictitious time, isSend () definition or isGroupSend () definition return value are true time, then this passage prioritization.When passage possesses the mass-sending function, promptly isGroupSend () method return value is true, this passage prioritization.

Illustrate as follows.Existing three short message channel A, B and C.Wherein A, B all possess the mass-sending function, i.e. A, and isGroupSend () the method return value of B passage is true, but the B passage can not receive note, and promptly the isReceive () return value of B be vacation.C-channel can not be mass-sended, i.e. the passage of C-channel description definition isGroupSend () method return value is false.A, C all possess the reception SMS, and promptly the isReceive method of A, C is very.According to above-mentioned queueing discipline, then putting in order of passage A, B and C-channel is followed successively by B, A and C.The preferential B passage of selecting when promptly sending note, next selects A channel, and the like.

Definition 4) mainly be called when sending note, promptly canSend () method return value is a true time, calls the sending method of this passage, and middle parameter is a phone number.

Definition 5), 6), 7) and 8) be mainly used in the interface display parameters to the user to show difference.

With reference to Fig. 2 the channel adapting method of Short Message Service interface of the present invention is elaborated below.As shown in Figure 2, in the channel adapting method of described Short Message Service interface of the present invention, described channel manager communicates by mutual step and process by the adaptive passage expansion interface of ISP and ISP or short message equipment, described channel manager is after beginning, described each passage of initialization (sending start) and ISP or short message equipment (sending Init) sort to passage according to following arrangement of passages algorithm: the passage prioritization that the passage priority level is high then; Then, it is preferential that the passage that priority is identical does not possess the passage of mass-sending function; The passage that possesses ability to accept when at last, having mass-sending function identical (all possess or do not possess) is preferential.

When short message sends request, with reference to Fig. 3 the channel selecting algorithm is described, describe the algorithm of selector channel in detail below with reference to Fig. 3:

At first judge whether to exist a passage? when having a passage,

Choose passage successively, judge then whether this passage can send this purpose phone number,, then continue to select next passage if can not send;

Then the running status of passage is judged, is stopped or abnormality, then continue to select next passage if passage is in,

Judge busy, the not busy state of passage at last,, then continue to select next passage if passage is in busy state;

Call the passage sending method, if passage sends failure continuous 10 times, then the mark channel state is an error condition.Whether system sends the return results that passage sendSMS method is depended in successful judgement to note.Return results if this is tabulated and is sky, shows then that all notes have all sent success for sending the phone number tabulation of failure.If all passages all can not send, show that then this message sends failure.

Flow chart illustrated in greater detail below in conjunction with Fig. 2 is as follows: if existing three passage A in the system, B, C.Wherein A channel is the proprietary passage of China Mobile, can only send a message to China Mobile network the cellphone subscriber.The B passage is the proprietary passage of CHINAUNICOM, can only send a message to the mobile phone of CHINAUNICOM's network.And C-channel is to utilize proprietary equipment to carry out the passage of note, can send a message to the mobile phone of the network of CHINAUNICOM and China Mobile.Putting in order of passage is followed successively by A, B, C.When this channel manager of startup is managed this passage, A will be called automatically, B, the startup method of C-channel.Start successfully, we are set to running status at channel status.

Need send to phone number as a note is that 13034567788 such users are when (this phone number belongs to CHINAUNICOM).At first, this operation system is given A channel by channel manager with this note and is sent, and promptly at first calls the canSend method (as Fig. 2) of this passage.A channel can only send the phone number of China Mobile, can not send so return.System continues to give next channel B passage with message, calls its canSend method.Cell-phone number and operation that the B passage can send CHINAUNICOM are normal, then this short message are given this passage and are sent.When situations such as (connect as network and interrupt) occurring unusually when the B passage, the B channel status has become error condition, perhaps works as the B passage also in the note that sends submission last time, and when being in busy state, system then selects next channel C to send.After the selected good passage, the sendSMS method of calling this passage is sent message, then, passage sends (send) short message to ISP or short message equipment, sends short messages to the cellphone subscriber by ISP or short message equipment.Fail in process of transmitting (connect as network and interrupt, situations such as (outages) unusually appears in equipment) when the passage of selecting, then the transmission frequency of failure with passage adds up 1 time, and when continuous failure 10 times, then the state of this passage becomes abnormality automatically.When system stops, the Stop method of three passages will be called automatically.Passage is carried out corresponding shut-down operation (as closing network connection etc.).

When mobile phone sends short messages to ISP or short message equipment, and when ISP or short message equipment send (send) message to passage, this passage is received a short message, when receiving from 13828840760 short message, will call the onMessage () method of ISMSListener and handle the short message that receives as passage A.

Wherein ISMSListener is a general interface, is realized voluntarily by operation system.The details that realizes depends on operation system fully.Can in onMessage () method, the information that receives be deposited into database such as you, and print on the computer screen.Even you can realize corresponding note distant control function by onMessage method driving hardware.

In the channel adapting method of Short Message Service interface of the present invention, also in the short message of each transmission, be provided with different identification codes, to realize two-way short message track algorithm, be used to identify the short message of transmission, subsidiary this identification code in the short message that returns, by the channel adapting method of Short Message Service interface of the present invention discern this return short message at short message, in order to follow the tracks of the answer message of different short messages, thereby prevent to have adopted different passages to send each short message of different cellphone subscribers under the channel adapting method situation of Short Message Service interface of the present invention, form external asynchronous, reply order and upset the chaotic problem of bringing.

Described two-way short message tracing process is as follows:

This two-way short message is followed the tracks of mutual each time between operation system and the mobile phone with identification code sequenceNo, for same mobile phone sequenceNo is unduplicated, the general numeral that increases progressively that adopts is represented, because 0～9 is used as the quick sign indicating number of uplink service, therefore, this sequenceNo is since 10.

Generally guarantee in each passage: telephone number with following 2 kinds of modes: when the available phone number of passage more for a long time, as above 10000, available different telephone number comes corresponding different sequenceNo, this sequenceNo is invisible to the cellphone subscriber, directly answers the short message that receives by the cellphone subscriber and gets final product.Content encoding: in content of short message, add the sequenceNo explanation, add the sequenceNo code when replying, but this kind mode is slightly loaded down with trivial details to the cellphone subscriber by the cellphone subscriber.

For example: send SMS message: Mr. 1100A requires newspaper 1111 yuan of the taxi expenses in February that disappear.Wherein, the 1100th, the sequenceNo code, the back is a Mission Profile.

Mobile phone replying short message: 1100*1 then

Wherein, the 1100th, mission number, * is the function segmented word, the 1st, reply content.

Another mode is the mode that adopts telephone number to replenish.General, by to mobile operator (China Mobile, CHINAUNICOM) application note special service number, can send note to target mobile phones, the transmission phone number that shows on the target mobile phones is this special service number.Special service number as Chinese Central Television's Spring Festival Party is that the mobile subscriber is 8898, and the user of UNICOM is 9898.The note of then using the spectators of mobile operator mobile phone to receive shows from 8898, and the note of using the spectators of UNICOM's communication common carrier mobile phone to receive shows from 9898.Because this special service number allows client to expand voluntarily in the agreement of UNICOM, mobile operator, and target mobile phones when replying this note passage can get access to this number automatically.Promptly 8898 back can be connected in series the number of certain-length.As 889812345,889812346.Be that the transmission number that shows on the mobile phone can be 889812345 or 889812346.When target mobile phones was replied this note, passage can also get access to this transmission number except can getting access to the target mobile phones number.Concrete expansion length can be referring to the CMPP of China Mobile agreement or the SGIP of CHINAUNICOM agreement.

The present invention has utilized the extendible such characteristics of special service number just.When sending note, serial number SequenceNo is serially connected in the special service number back sends to target mobile phones.After target mobile phones is received, directly reply this note.Same.When passage is received the answer short message of target mobile phones, according to the sender's number that gets access to.Carry out corresponding rule and resolve, obtain original serial number SequenceNo.Owing to have certain corresponding relation between the origination message of serial number SequenceNo and transmission.In order to guarantee the uniqueness of flowing water, serial number certainly will increase progressively.Thereby increase progressively the too fast maximum length restriction that special service number expands that surpasses for fear of serial number, the generation that present corresponding relation is a serial number is relevant with short message content and phone number.I.e. serial number+phone number assurance is unique, and same phone number serial number increases progressively 1, and radix is since 10.

Illustrate as follows below:

Sending for the first time note to mobile phone 13824376207 and 13828840760, is 11 at 13824376207 serial numbers that produce then, is 11 at 13828840760 serial numbers that produce.When sending note once more to 13824376207 the time, the corresponding serial number of generation is 12, and sends note once more by 13824376207 o'clock, and then the serial number of Sheng Chenging is 13.In like manner, sending the serial number that note produced by 13828840760 o'clock once more is 12.

When system sends note, automatically carry out once corresponding with the transmission note serial number and phone number and preserve this corresponding relation, for every note of transmission, system will give this note a unique sign ID automatically.

The example of concrete preservation form is as follows:

The unique sign of note ID note receives the phone number serial number

1234 13824376207 11

1234 13828840760 11

1235 13824376207 12

When passage is received the answer short message of target mobile phones, according to target mobile phones number and the serial number that parses, just can find corresponding source to send message, thereby know that this answer message is at the answer of which bar note.

Be exemplified below:

The special service number of passage is 075524.

System sends a piece of news to target mobile phones 13824376207, thes contents are as follows:

" Mr. A apply for reimbursement February taxi expense 1111 yuan ", the serial number that passage generates for this message is 1100.During transmission, system will carry out once corresponding with 1100 with this note automatically.Prepare against and search pairing when receiving answer short message.

When the cellphone subscriber when 13824376207 received this message, then the transmission number of target mobile phones demonstration was 0755241100.The user directly replys this note " agreement ".

Passage is received the answer short message from mobile phone 13824376207.Except that getting access to content and phone number, can also get access to this transmission number 0755241100, passage is resolved this transmission number automatically and is obtained serial number 1100.By aforementioned said corresponding relation, thereby learn that this note is the answer at " Mr. A apply for reimbursement February taxi expense 1111 yuan ".Reply content is " agreement "!

Because the generation of serial number is only relevant with the reception phone number of note, promptly this serial number is unique for a phone number.So when this serial number is received by system, promptly can find corresponding source transmission message accurately according to this serial number and transmission phone number.Thereby improved above-mentioned said chaotic problem.

Thus, the inventive method can realize providing unified short message interface to operation system, and need not to be concerned about by which kind of passage transmitting-receiving short message; The channel adapting method of Short Message Service interface of the present invention is to management and the scheduling by channel manager of the ISP of various Short Message Service system or short message equipment, and identify at different short messages, in order to follow the tracks of the bidirectional transmit-receive of short message, improved operation system and cellphone subscriber's short message interaction capabilities, and need not to depend on a certain side ISP or short message equipment, strengthened the stability of the message function of system.

It will be apparent to one skilled in the art that various modifications and changes may be made in the present invention under the situation that does not break away from the spirit or scope of the present invention.Therefore, the invention is intended to cover the modifications and variations that drop on this invention in claims and their the equivalent scope.
