Abstract

The method improves the mobile talkback service in order to breakthrough the limitation of speak-right such that the sending end can transmit the voice message to one or more recipients with no needs to wait a confirmation. With both ways of voice packet and voice stream transmission, the low voice quality caused by merely voice stream transmission is improved, and with the forwarding and saving of mobile phone server, the limitation to ask that both sides of talkback must be on-line is solved. By saving the voice message at server and client sides, the voice message can be listened in many times.

Description

The method of processed voice information in a kind of mobile intercommunication business
Technical field
The present invention relates to mobile data communication, during particularly mobile intercommunication is used, transfers voice information between the portable terminal is finished voice messaging storage and the implementation method transmitted with the cooperation of server software and relevant support hardware (common name server) by the client software (common name client) that is installed in the portable terminal.
Background technology
In traditional mobile intercommunication particularly in the mobile phone intercommunication business, several characteristics below existing:
1. the affirmation of right to speak: the user is utilizing client to send one section speech message to one or more other portable terminals (just usually said intercommunications, wherein the voice messaging originating end is called the calling subscriber, the voice messaging receiving terminal is called the called subscriber, in an intercommunication process, the calling subscriber is one, the called subscriber can be one, also can be a plurality of) before, earlier the client of initiating by intercommunication sends instruction to service end, and this moment, tool had the right to speak to determine intercommunication to initiate the user.If any, then can send speech message, if not then can not send voice messaging.
2. the voice messaging in the intercommunication only transmits in the mode of voice flow: voice messaging is initiated the user when utilizing client to send voice messaging to one or more other portable terminals when intercommunication, the voice messaging that send directly sends to called subscriber's client or arrives called subscriber's client by server forwards in the mode of voice flow.Just usually said real-time transmission receives in real time, plays in real time.
3. do not store the voice messaging that produces in any intercommunication process in user's intercommunication mobile phone: the calling subscriber utilizes client to send voice messaging after one or more other portable terminals, no matter be to send in voice messaging or the portable terminal at receiving speech information, the voice messaging that produces in the intercommunication process is not all stored.That is to say that voice messaging after sending and receive and playing simultaneously, disappears immediately.
4. sender recipient status checkout is confirmed: the calling subscriber is utilizing client to send voice messaging to one or more other portable terminals, by client with the particularly cooperation of the User Status processing module in the server of the cooperation of service end, confirm whether oneself or recipient are in the state of normal connection and receiving speech information with server, and whether just usually said is online.As long as have a side to be in not presence, just can not send voice messaging.
The above several characteristics of tradition in the mobile intercommunication, several defectives or deficiency below the user can exist in to the use of business:
1. the affirmation of right to speak: the general user is at every turn when intercommunication, selecting earlier oneself needs the object of transmission, directly just say then, and do not know or uncomfortablely at first oneself will consider, own this moment, whether tool had the right to speak, and can patient wait client cooperates with service end and confirm this right to speak.The existence of this " affirmation of right to speak " mechanism has changed user's use habit, has increased user's use difficulty greatly, has increased the time delay that voice messaging sends simultaneously.This has not only improved the user and has used professional threshold, and gives disagreeableness business experience of user.
2. voice messaging only transmits in the mode of voice flow, and play in real time: higher when voice messaging only transmits in the mode of voice flow in user's intercommunication process stability of network and bandwidth requirement, if the network bandwidth is not enough, or stability is not high, and voice quality can not well be ensured.Because mobile network's characteristic; except also not possessing the Internet such stability and bandwidth; the user is in mobile phone through regular meeting does not have signal, mobile data network not to have the inconvenient receiving speech information of signal, called subscriber's shutdown, called subscriber's busy call, user, voice messaging inconvenience various states such as to play back in real time; can cause voice messaging losing or bring inconvenience in transport process to the called subscriber; can have a strong impact on the service quality of mobile phone intercommunication business and user's use interest, even cause professional actual can not the use.
3. do not store any voice messaging in user's intercommunication mobile phone: this voice messaging that requires the calling subscriber in the intercommunication to send complete receiving terminal that arrives the called subscriber in real time of to try one's best, if the packet loss phenomenon appears in the reason owing to network in the process of transfers voice information in real time, the recipient can't hear the voice messaging that high-quality is complete, and the called subscriber is required to work as the inferior voice messaging that the calling subscriber sends over of catching simultaneously; This is except to the having relatively high expectations of stability of network and bandwidth, environmental requirement during simultaneously to the speaking of calling subscriber and called subscriber both sides is higher, at one is not very quietly in the environment, can cause the other side's that both sides can not catch in real time voice messaging content.Since in the mobile data network himself, the user is again at one relatively quietly in the environment when can not guarantee fully usually that network is stable.The existence of this treatment mechanism can cause the user to require identical voice content to increase the cost that the user uses the intercommunication business through repeatedly sending and playing owing to often not catching the voice messaging content that the other side sends over.
4. the affirmation of sender recipient presence: this requires caller and called subscriber must be in simultaneously in the normal accepting state of voice messaging.If the user is when sending voice messaging, because mobile network's characteristics, if any a side in call, the existence of factors such as out of reach, shutdown, can not guarantee fully that caller and called subscriber both sides are simultaneously online, at this moment the user just can not use mobile intercommunication business.Just the user thinks, but not talkative, has lost the person's character of mobile intercommunication, has reduced the professional convenience of using of intercommunication, has improved the user and has used professional threshold, has reduced the user and has used professional interest.
Summary of the invention
The object of the invention is, improve the problems referred to above that exist in traditional mobile intercommunication,, improve the voice service quality solving the professional cost that the user uses business that network requirement is reduced in the higher problem, improve arrival rate of message, thereby improve the availability and the subscriber usage of whole service.
This method major technique is contemplated that:
1. at traditional characteristic 1, improve " right to speak affirmation " mechanism; The user no longer needs to wait for " right to speak affirmation " in the intercommunication process.The user is when wanting to send voice messaging, as long as select one or more objects of sending wanted, the direct recording voice messaging sends, just said usually " just take up and say ", the use habit that meets the user like this, can reduce the difficulty of user's use intercommunication business greatly, shorten the time delay (owing to having removed the affirmation process of user's right to speak) that voice messaging sends, when the reduction user uses the threshold of intercommunication business, give good business experience of user.
2. at characteristic 2,3, improve original " voice messaging only with the mode of voice flow transmit and play in real time, the mobile phone end do not store any voice messaging " be " voice messaging transmits with the mode of voice document message in the mode of stream and transmits; the while stores at the transmitting terminal and the receiving terminal of voice messaging " mode, can guarantee that at network information is unlikely to lose when particularly the mobile network is unstable; Simultaneously the user can utilize and be stored in the portable terminal voice messaging file and can repeatedly play, up to oneself feel clear till, can guarantee like this, even in the assorted environment that makes a noise very much, the clear said each other content that the user of both call sides can both be perfectly clear; In addition, the existence of terminal storage voice document mechanism, can guarantee the user when being inconvenient to listen to voice messaging (as meeting, busy, have a rest, be inconvenient to listen and wait the individual special time in other words) user can utilize the voice messaging that is stored in the portable terminal, at the convenient time listen to, can make things convenient for the effective communication between the user greatly.
3. at characteristic 4, improve " affirmation of sender recipient presence ", allow the voice messaging sender as long as the mobile intercommunication client of opening installation in mobile phone, no matter be online or not online, no matter the recipient is online still not online, can whenever and wherever possible after choosing the reception object, directly can send voice messaging entirely.When laying oneself open to not presence, the voice messaging that send temporarily is kept in the mobile phone of oneself in the mode of voice document, but when the recipient is in accepting state, automatically voice messaging is sent to the recipient.The recipient is not online if oneself is online, voice messaging one document form can be stored in the server, in case but the other side is in the receiving speech information state, and server sends to the recipient with voice messaging automatically.Can guarantee that so no matter under any circumstance, the voice messaging initiator can send voice messaging whenever and wherever possible.As long as the recipient is in accepting state, just can receive information, improved the validity that information sends greatly, improved the success rate that voice messaging sends simultaneously.
Technical scheme of the present invention is as follows:
The method of processed voice information in a kind of mobile intercommunication business, structure based on the server and client side, and client is with the cooperation of portable terminal, described client is voice messaging transmitting terminal and voice messaging receiving terminal, it is characterized in that may further comprise the steps: step 1, the voice messaging transmitting terminal judges oneself whether to be in normal voice information transmit status, if then voice messaging is divided into some sound bites and records order by information and send to server; If not, then voice messaging temporarily is stored in the portable terminal, and when the voice messaging transmitting terminal was in normal transmit status, this voice messaging was sent to server; Step 2, server judge whether the voice messaging receiving terminal is in normal accepting state, if then the order that sends of the information segment that receives by server sends to the voice messaging receiving terminal with voice messaging; If not, then voice messaging temporarily is stored in server, in case server is learnt the voice messaging receiving terminal and is in normal accepting state, server just sends to the voice messaging receiving terminal with the memory address of voice messaging in server, and the voice messaging receiving terminal can be downloaded the VoP of this voice messaging by this address from server.

C. voice messaging is after being sent out or receiving, and sending and receiving terminal is keeping in the mode of voice messaging file;
D. when reception information side is in improper accepting state, the voice messaging that is sent out is retained in the server, before information does not surpass the term of validity, in a single day receiving terminal is in accepting state, server sends to receiving terminal with the memory address of voice messaging in server, collects voice messaging for receiving terminal;
E. it is not online to work as the user, this moment can not send with receiving speech information time the just, the user still can recorded speech information, if receiving terminal enters presence prior to transmitting terminal, then when transmitting terminal entered presence, voice messaging directly was forwarded to receiving terminal by server; If transmitting terminal enters presence prior to receiving terminal, the voice messaging that then records transmits server by the cooperation of client and service end with voice messaging, and temporarily be retained in server, in case receiving terminal enters presence, then send to receiving terminal with the voice messaging that the cooperation of server will be stored in the server by receiving terminal.As shown in Figure 1, the present invention is based on server and client side's structure, and client is with the cooperation of portable terminal, and described client is voice messaging transmitting terminal and voice messaging receiving terminal (one or more receiving terminal).Its technical characterictic is:
When a) mobile intercommunication user used business, the calling subscriber did not need to carry out " affirmation of right to speak ", after choosing the object that will send, can directly speak, and sent voice messaging;
When b) mobile intercommunication user used business, the mode that voice messaging utilizes voice flow and voice document to combine transmitted;
When c) mobile intercommunication user used business, voice messaging was stored in mobile phone terminal after being sent out and receiving;
D) mobile intercommunication user is when using business, can not consider whether the object own or information of reception is in normal transmission and accepting state, the direct recording voice messaging, when laying oneself open to normal transmit status or receive object when being in normal accepting state, voice messaging is sent out and receives;
When e) mobile subscriber uses intercommunication professional, when voice messaging reception object is in improper accepting state, can utilize the cooperation of client and service end, voice messaging is stored in the server, in the term of validity of information, in case when the message pick-up object was in the accessible information state, voice messaging will be sent straight to the recipient or server sends to receiving terminal with the memory address of voice messaging in service, receiving terminal extracts voice messaging according to the address of voice messaging from server.
Concrete steps are as follows:
Step 1, the user is when using mobile intercommunication professional, and the professional promoter of intercommunication selects one or more recipients' sign by client, is ready for sending voice messaging, just prepares the beginning intercommunication;
Step 2, the user pins the intercommunication key, and beginning recorded speech information just begins to carry out intercommunication;
Step 3, intercommunication are initiated subscription client and are judged oneself whether to be in normal voice information transmit status.If be in normal transmit status, then voice messaging is divided into some sound bites and records order by information and send to server; If be in very transmit status, voice messaging temporarily is stored in the mobile phone, and before information initiation user oneself had deleted this part information, as long as client is in normal transmit status, information was sent to server;
Step 4, server judge whether the receiving terminal of voice messaging is in normal accepting state.If be in normal accepting state, then the order that sends of the information segment that receives by server immediately sends to receiving terminal with information; If be in improper accepting state, then voice messaging temporarily is stored in server;
Step 5, for the client that temporarily is in improper receive status, in case server is learnt client and is in normal accepting state, server can send to the memory address of voice messaging in server the reception client of voice messaging, and client is downloaded voice messaging by this address from server;
Step 6, voice messaging arrive and receive after the client, and intercommunication receives the user and listens to voice messaging.
In described step 1 and the described step 2, when the initiation user selects one or more recipient to indicate by client, need not carry out " affirmation of right to speak ", after choosing receiving terminal, directly intercommunication sends voice messaging;
In the described step 2, after the initiation user pinned the intercommunication key, terminal was preserved voice messaging, and the user can listen to recording result repeatedly, avoids transmitting the low quality voice.As transmitting terminal is abnormal condition temporarily, and when it was in normal transmit status, the voice that are stored in terminal still can send by client.
In the described step 3, send client as being in normal transmit status, then voice messaging is divided into some sound bites and records order by information and send to server, is actually the form with voice flow, and voice messaging is sent to server.Be in improper transmit status when sending client, this moment, client direct recording voice messaging was kept at terminal as described in the epimere, and when sending client and be in normal transmit status, voice messaging is sent out.
In the described step 4, server is judged: if receiving terminal is in normal accepting state, server sends to receiving terminal by the order that the information segment that receives sends with information immediately.Be actually the form of server, be dealt into receiving terminal receiving the voice messaging that comes from transmitting terminal with voice flow.
In described step 4 and the step 5, if receiving terminal is in improper accepting state temporarily, server will be preserved into voice document with certain form receiving the voice messaging that comes, be in normal accepting state in case learn receiving terminal, server can this voice document memory address issue receiving terminal, receiving terminal is downloaded voice document by the address.In fact this voice messaging is that form with voice document is received end and obtains.
In the described step 6, after voice messaging arrived and receives client, intercommunication received the user and listens to voice messaging.Simultaneously, receive client this voice messaging is kept at terminal.Receiving the user can at the convenient time listen to.
Further specify improving one's methods of this mobile intercommunication, wherein
1.1) initiate the user and open client, select one or more voice to receive objects, by the intercommunication key, the beginning intercommunication.This moment, the user need not consider whether oneself has " right to speak ", also need not consider oneself or receive whether the user is normal condition.
1.2) intercommunication initiates the user and judge whether oneself is in the normal voice transmit status.In a single day no matter whether be in normal voice transmit status, all can when being in normal condition, send voice messaging to server.In addition, voice messaging is stored in mobile phone terminal, before user oneself deletion, can listen to repeatedly.Initiating the user can the verification sound effect.
1.3) after server receives and initiate user's voice information, will judge whether receiving terminal is in normal accepting state.
