Embodiment

Below in conjunction with accompanying drawing, the embodiment of the invention is described in further detail.

The embodiment of the invention is to realize a kind of technology of preknowing topic of call on mobile communication terminal, when calling out terminal called, send the information of call subject by calling terminal, thereby make terminal called when receiving the call request of calling terminal, show the theme of current talking.

Embodiment one,

Fig. 1 is the flow chart of the communication means of the embodiment of the invention one preknowing topic of call.This flow chart may further comprise the steps:

101, receive the called terminal number and the topic of call information of input;

102, conversion calling terminal number and subject information are in the call set up signaling that has set in advance the topic of call element;

103, send described call set up signaling to communication network, be sent to terminal called by described communication network.

In the embodiment of the invention, the user in order to allow the user of terminal called understand the purpose communicate with, can import the subject information of this communication before and after the input called terminal number, is dialing called terminal number after having imported subject information, thereby is communicating by letter with its foundation.That described termination number refers generally to use always at present is telephone number, MSRN (Mobile Station RoamingNumber, travelling carriage roaming number), generally is digital information, or network identification mark, generally is the various combinations of literal and numeral.Because subject information can not directly enter communication network, transmits so will be converted into the information format of communication network support.When setting up with the communicating by letter of terminal called with calling terminal earlier the transmission call set up signaling realize, so in the present embodiment calling terminal number and subject information are converted to the information that call set up signaling is supported, finally send described call set up signaling and be forwarded to terminal called by communication network.

But because existing call set up signaling does not support to transmit the form that comprises subject information, so will expand setting to the communication protocol between communication terminal and the communication network.And answer the theme of knowing before from calling party's conversation in order to be implemented in the callee, at first the communication protocol between communication terminal and the communication network need be expanded, and increases the agreement of the transmission information of topic of call on the basis of existing call information.Increasing an information element (Information element) in the content of the embodiment of the invention with the call set up signaling (SETUP signaling) stipulated in agreement Q.931 is example, and this information element is defined as follows:

Wherein, information element (Information element) title is defined as topic of call (Calltopic); Communication direction is defined as two-way, promptly this signaling can send to server (communication network) from communication terminal, also can send to communication terminal from server; Communication type being defined as " 0 ", being option, is not the field element that must carry, if the user does not import content when making a call, then can skip this field; The length of information element is defined as 2-20 byte, and the field length of this information element is unsuitable oversize, in order to avoid influence efficiency of transmission.

The advantage of the embodiment of the invention is to set up the theme of passing on caller calls when calling out with the callee, helps the callee and selects to answer calling party's call request according to the theme that receives, and has improved the efficient with callee's conversation greatly.

Embodiment two,

Fig. 2 is the flow chart of the communication means of the embodiment of the invention two preknowing topic of call.This flow chart may further comprise the steps:

201, receive the called terminal number and the topic of call information of input;

202, conversion calling terminal number and subject information are in the call set up signaling that has set in advance the topic of call element;

203, send described call set up signaling to communication network, be sent to terminal called by described communication network;

204, the step of described called terminal number of storage and the described call subject information that sends out.

Present embodiment is compared the theme of not only passing on caller calls when foundation is called out with the callee with embodiment one, help the callee selects to answer the calling party according to the theme that receives call request, but also can store the subject information of called terminal number and transmission, make user's information such as call number, theme of being more convenient for from now on searching.

Embodiment three,

Fig. 3 is the flow chart of the communication means of the embodiment of the invention three preknowing topic of call.This flow chart may further comprise the steps:

301, the call set up signaling that has set in advance the topic of call element of received communication network transmission;

302, resolve described call set up signaling;

303, according to the described call set up signaling that parses, calling terminal number and call subject information that the display of calling terminal sends.

In the present embodiment, after terminal called receives the call set up signaling of communication network transmission, resolve described call set up signaling, because described call set up signaling comprises information such as calling terminal number and subject information, so terminal called responds the information that parses one by one, comprising the number of ring on the display screen of terminal called and display of calling terminal and the topic of call of calling terminal input.

The advantage of the embodiment of the invention be when receiving the number of calling terminal simultaneously display of calling side wish the subject information that communicates, understand the calling party and want purpose, topic of call or the relevant information of other conversations conversed.Make the callee to judge whether incoming call answering, improved the efficient of conversing with the other side greatly, compare with prior art and also further reduce the waste of blindly answering on the time and money that brings according to these information.

Need to prove that the call set up signaling in the embodiment of the invention has also been carried out expansion setting, its method is identical with embodiment one, so no longer be repeated in this description.

Embodiment four,

Fig. 4 is the flow chart of the communication means of the embodiment of the invention four preknowing topic of call.This flow chart may further comprise the steps:

401, the call set up signaling that has set in advance the topic of call element of received communication network transmission;

402, resolve described call set up signaling;

403, according to the described call set up signaling that parses, calling terminal number and call subject information that the display of calling terminal sends.

404, the described calling terminal number that goes out of storing and resolving and the step of call subject information.

Present embodiment is compared with embodiment three has increased the described calling terminal number that storing and resolving goes out and the step of call subject information.Because the callee does not in time look at calling party's incoming call request probably owing to some reasons, so behind calling party's termination telephone, described calling terminal number and call subject information that terminal called wants storing and resolving to go out, thereby make the callee can see the record of the request conversation that the calling party sends before afterwards, and calling party's number is arranged not only in this record, and there is the calling party to wish the subject information of conversing with the callee, in time understand the calling party and want the purpose conversed, whether make the callee can judge missed call is harassing call or dangerous phone or useful phone, further improve the efficient of conversing with the other side greatly, compared the waste that also further reduces on the time and money that brings of blindly wiring back with prior art.

Embodiment five,

The embodiment that present embodiment shows in the mode of twinkle SM for the topic of call information that shows among the embodiment three.Terminal called can show that topic of call information must satisfy two necessary conditions in the twinkle SM mode: a condition is the twinkle SM business that the callee has selected common carrier, and the server in the communication network of operator will be sent to the callee in the mode of twinkle SM after receiving the message that the calling party sends at every turn like this; Another condition is that the terminal called that the callee uses must be supported function of flash message, like this could be with twinkle SM mode display message after having resolved the signaling that receives.With embodiment three is example: suppose terminal called support function of flash message.After terminal called is resolved call set up signaling, the beginning ring, and on screen, show twinkle SM content (flash SMS), calling number (identifier of caller communication terminal) is carried into terminal called (promptly as the source address content of information, at terminal called, this flash SMS can shine upon calling number with the name in the phone directory so mutually from calling terminal).Its principle is as follows: because 3GPP has stipulated four kinds of ranks to information (message), as shown in the table:

Table 1

Wherein, when Bit1 and Bit0 are " 0 ", levels of information is that Class is 0, the message that the communication terminal reception is worked as in i.e. expression is " 0 " rank, and when communication terminal has the function that shows twinkle SM, communication terminal will show this twinkle SM content immediately, and no matter whether SIM card or communication equipment have enough memory spaces, as long as twinkle SM successfully arrives communication terminal with signaling and all will send validation of information to Short Message Center.But this twinkle SM can not be stored on SIM card or the mobile device automatically.When levels of information is Class1, information is defaulted as specifies mobile device (ME-specific), when levels of information is Class2, information is for specifying the information (SIMspecific message) of SIM, when levels of information was Class3, information was defaulted as the information (TE specific) of designated terminal equipment.For the communication terminal of not supporting twinkle SM, can directly ignore other Bit1 of identification information level and/or Bit0 position, think that this message does not have rank, and the twinkle SM that receives is handled as the common short message breath.

Present embodiment and embodiment three compare advantage and are the subject information that can send with the mode display of calling side of twinkle SM with embodiment four, the information user who shows does not store in SIM card or terminal equipment after reading by this way, not only well reached the purpose that shows topic of call when conversing, and the memory headroom of occupied terminal the characteristics of the technical program as a kind of instant messaging means have not well been embodied with the callee.

Embodiment six,

Present embodiment is that example specifies with the foregoing description, and the communication terminal in the present embodiment is an example with the mobile phone, supposes that the party A-subscriber wishes to carry out voice communication with mobile phone X and party B-subscriber's mobile phone Y.Fig. 5 is the flow chart of the communication means of the embodiment of the invention six preknowing topic of call.This flow chart may further comprise the steps:

601, mobile phone X receives the topic of call of party A-subscriber's input: " renting a house ";

602, mobile phone X receives the party B-subscriber's of party A-subscriber input the number of mobile phone Y;

603, mobile phone X hand over word " is rented a house " and the number of mobile phone Y is the information that call set up signaling is supported;

604, mobile phone X sends the call set up signaling the comprise described information server (MSC/VLR) to the communication network;

605, after MSC/VLR obtains the number of mobile phone Y, send calling to mobile phone X and carry out message (Call_Proceeding);

606, MSC/VLR is to terminal called, and promptly mobile phone Y sends call set up signaling, carries the number of mobile phone X and the character information that topic of call " is rented a house " in this call set up signaling;

607, after mobile phone Y receives described call set up signaling, resolve the information in the described call set up signaling;

608, mobile phone Y shows the number of mobile phone X and the character that topic of call " is rented a house ";

The party B-subscriber sees that mobile phone Y goes up the number of the mobile phone X that shows and the character that topic of call " is rented a house ", selects whether to answer the phone that the party A-subscriber makes.

Call set up signaling in the present embodiment has also been carried out expansion setting, promptly increases the element that conversation is set a question in described signaling, and its method is identical with embodiment one, so no longer be repeated in this description.Mobile phone X in the present embodiment and mobile phone Y can also store as " renting a house " the subject information of phone number and conversation, guarantee user's information such as theme of easy-to-look-up this conversation afterwards.

Present embodiment is based on above-mentioned each embodiment, and how the communication means that has specifically described a kind of preknowing topic of call of the embodiment of the invention is realized.Need to prove party B-subscriber in the present embodiment if will answer party A-subscriber's conversation, the communication mode that adopts all same as the prior art.
