Description

Realization Method of Preventing Missed Calls

technical field

The invention relates to the field of intelligent network new services, in particular to a call processing method.

Background technique

With the rapid development of communication technology, users may have multiple communication terminals at the same time, such as mobile phones, PHS, home fixed phones, office fixed phones, etc., so there are more and more communication methods available. The way is to use mobile communication terminals and fixed communication terminals to communicate. In the prior art, each terminal discloses a number to the public respectively, which may cause people in contact with the user to only know one of the user's terminals (such as office fixed phone), but does not know the number of other terminals (such as mobile phone, PHS or home fixed phone) of the user, so it is possible that the user misses the call from the contact. Of course, in order to avoid this In the event of a missed call, the user can carry multiple terminals at the same time, but this method is very inconvenient and unrealistic.

In order to solve the occurrence of missed calls caused by users owning multiple terminals, people in the industry have proposed the Universal Personal Telecommunication (Universal Personal Telecommunication) service, that is, the "one number" service. A user who has applied for the "one number" service only needs to disclose a "one number" number to the outside world, and all called users who call the user only need to dial the "one number" number to call the user. The call connection rule is to make each terminal of the user ring in sequence until the user uses one of the terminals to answer the call. It can be seen that the "one number" service can indeed solve the problem of missed calls caused by users owning multiple terminals. However, if the user uses the "one number" service, he needs to notify all his contacts in advance, and then call the "one number" number he needs to dial. Therefore, there are often too many contacts that need to be notified, which brings great inconvenience to users in the general use of the "one number" service. Cause the problem of missing the incoming call of the contact; at the same time, because each time a new contact is added, it is necessary to notify the new contact of its own "one number" number, so it also causes users to generally use the "one number" service. A long process.

In order to solve the situation of missed calls caused by users owning multiple terminals, people in the industry have also proposed transfer services such as call transfer and busy transfer, but when performing call transfer according to the transfer methods provided by the above services, it is necessary to terminal to configure. If there are too many transfers per day for each terminal, it is very troublesome to set it up multiple times; This is a very cumbersome work, so this transfer service makes the user feel very inconvenient to use. Users generally only apply this transfer service to transfer calls between two terminals, because it is very inconvenient to use this transfer service if it is used between more terminals.

Contents of the invention

The technical problem to be solved by the present invention is to propose a realization method for preventing missed calls, so as to comprehensively prevent various missed calls from happening, and it is easy to use and popularizes quickly.

In order to solve the above problems, the present invention proposes an implementation method for preventing missed calls, which is used to prevent various missed calls from occurring in multiple terminals owned by the user, including:

(1) selecting a terminal among the plurality of terminals;

(2) establishing a mapping relationship with the number of the selected terminal and the number of each unselected terminal;

(3) When any unselected terminal is called, according to the mapping relationship of the numbers, the connection channel is transferred to the selected terminal, so that the selected terminal performs the voice channel connection as the called terminal.

Wherein said method also comprises:

(4) During the connection process, if the selected terminal cannot be connected, continue to transfer the connection channel to other terminals for voice connection;

(5) Judging whether the terminal is answered by someone, if yes, the caller and the called party directly talk; if otherwise;

(6) Continue to transfer the connected speech channel to the next terminal for speech path connection, and then go to step (5) to continue judging.

Wherein step (3) described in step (3) according to the mapping relationship of the number, before connecting the connected voice path to the selected terminal, it also includes: connecting the connected voice path to the unselected terminal, making the unselected terminal The terminal, as the called party, performs session connection.

The step (3) also includes: when transferring the connected voice path to the selected terminal according to the mapping relationship of the numbers, at the same time connecting the connected voice path to the unselected terminal, so that the unselected terminal As the called party, the terminal is connected to the session.

In the step (1), different terminals are selected in different time periods.

Beneficial effects of the present invention: the implementation method of the present invention to prevent missed calls selects one terminal among the multiple terminals of the user, and then establishes a mapping relationship between the numbers of the other multiple unselected terminals and the number of the selected terminal, in the When each terminal of the subsequent user is called, all calls can be transferred to the selected terminal for answering, thus more comprehensively preventing the occurrence of various missed calls. At the same time, since the number mapping relationship tables established in different time periods are stored on the network side, the user does not need to perform multiple settings, so the application is very convenient. Moreover, the user still discloses the original numbers of each terminal to the outside world, and there is no need to notify contacts of any number change information, so the popularization speed is relatively fast.

Detailed ways

The implementation method of the present invention to prevent missed calls is based on the existing communication intelligent network (IN, IntelligentNetwork), by mapping the numbers of multiple terminals of the user to the number of one of the terminals, when the subsequent connection, the calling user If you dial any terminal of the user, the call will be connected to the same terminal for answering, thus solving the problem that the user will not miss calls to other terminals on the premise that the user only carries his own terminal. The specific implementation process of the implementation method for preventing missed calls of the present invention will be described in detail below.

With reference to Fig. 1, this figure is the main process flowchart of the realization method that prevents missed call of the present invention; Communication terminals such as telephones, office fixed telephones, PHS, mobile phones, etc., each terminal will have a corresponding telephone number. With reference to Fig. 2, this figure is the implementation method of preventing missed calls of the present invention-the embodiment sketch map that user has a plurality of terminals and corresponding numbers thereof; User John himself has four communication terminals in this figure, is respectively: office phone, its The number is Number1; the home phone, its number is Number2; the PHS, its number is Number3; the mobile phone, its number is Number4. On the basis that user John owns the above-mentioned terminals, referring to Fig. 1, the specific process of implementing the implementation method for preventing missed calls is as follows:

Step 10, select one of the multiple terminals owned by the user, such as the user's home fixed phone, or the user's mobile phone, or PHS, office fixed phone, etc., which can be selected according to different time periods. different terminals.

With reference to Fig. 3, this figure is the number mapping relationship table that the implementation method of the present invention prevents missed call establishment in each time period; This section selects the mobile phone terminal, and its corresponding number is Number4, that is, the incoming calls to user John’s other terminals (office phone, home phone, and PHS) during the time period from 00:00 to 23:59 every Sunday are all The main reason for transferring to the selected mobile phone is that there are more opportunities to go out on weekends, so you will spend most of the time outside. Selecting a mobile phone to answer during this time period is the most accurate answering method. Similarly, John selects the PHS terminal from Monday to Saturday from 08:00 to 08:59, and the corresponding number is Number3, which means that from Monday to Saturday from 08:00 to 08:59 During this period of time, calls to user John’s other terminals (office phone, home phone, and mobile phone) are transferred to the selected PHS for answering. The main reason is that they are usually on the way to work during this period, so Selecting PHS to answer is the most accurate and economical answering method. And in the time period of 09:00 to 18:59 from Monday to Saturday, all calls to other terminals (mobile phone, home phone and PHS) are transferred to the office phone, and its number is Number1. The main reason is that I usually work in the company during this period, so choosing the office phone is the most accurate way to answer. Finally, all calls to other terminals (mobile phones, office phones and PHS) will be transferred to the home phone during the time period of 19:00 to 07:59 from Monday to Saturday, and its number is Number2. The main reason is that people are usually at home during this time, so choosing a home phone is the most accurate way to answer.

Step 20, establish a mapping relationship between the numbers of the terminals selected in step 10 and the numbers of other unselected terminals, that is, to make a one-to-one correspondence between the numbers of the selected terminals and the numbers of each unselected terminal. With reference to Fig. 3, this figure is the number mapping relationship table that the implementation method of preventing missed calls of the present invention is established in each time period; In this figure, user John selects an office phone, and its corresponding number is Number1 as an example to illustrate, as can be seen in the table , other unselected terminals of user John: home phone, its number Number2; PHS, its number Number3; mobile phone, its number Number4 corresponds to the selected office phone number Number1, according to this number mapping table, in the connection In this process, the actual number of the called terminal can be converted to the actual number of the connecting terminal, so as to realize the transfer of the connecting call.

Step 30, when any unselected terminal of the follow-up user is called, according to the number mapping table formed in step 20, the connected speech path connected to the actual called terminal is transferred to the selected terminal, so that The selected terminal is used as the called party to make the connection.

The data tables formed in Fig. 2, Fig. 3 and Fig. 4 can be stored in the database of the service control point (SCP, Service Control Point) of the communication intelligent network.

For example, when someone calls the home phone of user John, the number is Number2, the SCP in the intelligent network will first query the table in Figure 2, and find that the called number is Number2 for user John;

Then the SCP queries the table in Figure 3 according to the current call time. If the current call time is 10:28 am on Friday, then the SCP will index the following record after querying the table in Figure 3: john on Monday Saturday 09:00 18:59 Number1 (office phone)

After further querying the table in Figure 4, the SCP obtains that the actual number of the called terminal Number2 corresponds to the actual connection terminal Number1, and uses the number Number1 as the called number to transfer the connection line to the office phone of user John , that is, use John's office phone as the called terminal for subsequent connection and answering.

Of course, the specific content setting of the data table in the above-mentioned figure 3 is selected by the user himself. suppliers for adoption and storage.

After adopting the implementation method of preventing missed calls, the incoming calls from the outside world to each terminal of the user may be transferred to the selected terminal for answering, so for the user, it may not be possible to distinguish the calling user. Call your own by dialing your own terminal number. In order to prevent this from happening, an identification code can be set for each terminal of the user, and the identification code assigned to each unselected terminal must be different, so as to better distinguish them later.

With reference to Fig. 5, this figure is the flow chart of the realization method that prevents the missed call of the present invention from increasing identification code process; The specific processing process that can be identified when answering is as follows:

Step 40, assign an identification code for each terminal of the user in advance, with reference to Figure 6, this figure is a schematic diagram of the implementation method of the present invention to prevent missed calls for each terminal configuration identification code; in this figure, user John is his own Set the identification code to 8 for the office phone, set the identification code to 9 for your home phone, set the identification code to 7 for your PHS, and set the identification code to 6 for your mobile phone. The data table formed is also correspondingly stored in the communication intelligent network in the SCP for subsequent calls.

Step 50, when any unselected terminal is used as the called party, select the identification code corresponding to the unselected terminal number according to the number of the unselected terminal; as mentioned above, for user John, when the user's home phone When the terminal is not selected, and the home phone is used as the actual called terminal, the identification code 9 corresponding to the home phone number is indexed in the data table shown in FIG. 6 .

Step 60, the SCP in the intelligent network combines the identification code selected in the step 50 with the calling user's phone number, and sends it to the selected terminal for display; where the identification code and the calling number can be combined together through Place the identification code in front of the calling number, and separate the identification code and calling number with "*" or "#" for display. As mentioned above, when the identification code 9 is selected, the switching system combines the identification code and the calling number into a form of (9*calling number), and sends it to the selected terminal for display.

Step 70, after the user inquires about the incoming call number displayed on the selected terminal, and further checks the identification code in the incoming call number, he can distinguish which terminal the calling user is dialing; as mentioned above, the user John in On the display screen of the selected terminal, it is found that the incoming caller number displayed is (9*calling number), and the identification code in the incoming caller number is obtained as 9, and it can be identified that the calling user is dialing himself home phone to call your own.

Sometimes, although the user has used the implementation method of the present invention to prevent missed calls, in a certain period of time, the connection channel of the call to each terminal of the user is transferred to the terminal selected during this period to answer, but In some special cases, for reasons of convenience and economy, the user still wishes to use the actual called terminal to answer the call. For example, the user John selects the mobile phone as the selected terminal during the time period from 00:00 to 23:59 every Sunday, so that all calls to his other terminals will be transferred to his mobile phone for answering. , so that when user John goes out, he will not miss calls made to his other terminals. But on some Sundays, due to various reasons, the user John does not go out, but chooses to rest at home. At this time, if someone calls user John's home phone, user John still tends to answer it with his home phone, because this can save costs and reduce the radiation caused by answering with a mobile phone. In order to solve this problem, the implementation method of the present invention to prevent missed calls can further transfer the connected call path to the selected terminal or before transferring the connected call path to the selected terminal. The speech path continues to be connected to the actual called terminal for answering. As mentioned above, during the time period from 00:00 to 23:59 every Sunday, when the switching system receives the connection call for calling user John’s home phone, it transfers the connection call to user John’s mobile phone at the same time , and further connect the connected call to user John's home phone, or before transferring the connected call to user John's mobile phone, first continue to connect the connected call to user John's home phone. Furthermore, by setting the connection duration, user John's cell phone and home phone can ring at the same time, or the home phone rings for 10 seconds first, and then the cell phone rings, so that the user can selectively answer calls between the two terminals. . The purpose of such processing is mainly to consider the user's usage habits, because for many users, they tend to use fixed phones to answer incoming calls at home or in the office.

In some cases, it is very likely that the terminal selected by the user cannot be connected because the terminal selected by the user is in a call or is not in the network coverage area, but at this time another call is transferred. A missed call occurs, and the implementation method of the present invention prevents a missed call from selecting a plurality of terminals (comprising the selected terminal and each unselected terminal) to call the user one by one in order when the selected terminal cannot be connected. terminal) until a terminal answers the call. With reference to Fig. 7, this figure is the implementation method that the present invention prevents missed call, under the situation that the selected terminal cannot be connected, continue to call the process flowchart of other terminals; Its concrete implementation process is:

Step 80, the switching system forwards to step 90 when detecting that the selected terminal of the user cannot be connected;

In step 90, the SCP in the intelligent network will firstly control the switching system to transfer the connected voice path to the first terminal according to the order in which the user pre-sets its own multiple terminals (i.e. rank first in the order). One terminal), then the first terminal will ring, and a ringing duration can be set in advance for each terminal of the user, with reference to Figure 8, this figure is the implementation method of the present invention to prevent missed calls as Schematic diagram of configuring the ringing duration for each terminal; referring to the column with 4 consecutive numbers, it can be considered that the 4 terminal numbers are Number1, Number2, Number3 and Number4, which are arranged in the above order and set for the 4 terminals respectively The ringing time is 15s (due to the limitation of the working performance of the switch in the switching system, the ringing time of each terminal will not exceed 60s); on the first terminal.

Step 100, under the control of the SCP, the switching system judges whether the first terminal is answered within the duration of its own ringing, if yes, then go to step 120; if not, then go to step 110.

Step 110, the switching system continues to transfer the connected speech path to the next terminal, as in the example given in step 90, the switching system will continue to transfer the connected speech path to the terminal whose number is Number2, and the next After the terminal rings, turn back to step 100, and then execute steps 100 to 110 in a loop until one of the terminals answers the call.

Step 120, if someone has answered the terminal within the specified ringing time, then the normal call process can be carried out.

The implementation method for preventing missed calls of the present invention can further set an anti-disturb function for the selected terminal. With reference to Fig. 9, this figure is the implementation method of preventing missed calls of the present invention after the anti-disturbance key is set for the selected terminal, its entire connection process flowchart, the specific implementation is as follows:

Step 130, add an anti-disturbance key for the terminal selected by the user. The anti-disturbance key refers to an authentication code that the calling user needs to input when dialing the terminal of the called user. If the anti-disturbance key input by the calling user If the scrambling key is correct, the terminal of the called user will answer, otherwise the terminal of the called user will refuse to answer. The purpose of this processing is to prevent some harassing calls, and the contact person of the user is required to know the anti-disturbance key of the called user in advance.

Step 140, when any unselected terminal is called, transfer the connection channel to the selected terminal of the user for connection.

Step 150, when the SCP in the intelligent network detects that the selected terminal of the user is provided with an anti-disturbance key, it controls the switching system to require the calling user to input the anti-disturbance key.

Step 160, after the calling user inputs the anti-disturbance key, the SCP will compare the anti-disturbance key input by the calling user with the correct pre-stored anti-disturbance key, that is, the authentication process of the anti-disturbance key.

Step 170, judging whether the authentication of the tamper-proof key in step 160 is passed, if yes, go to step 190; if not, go to step 180.

Step 180, it is proved that the anti-disturbance key input by the calling user is wrong, so the SCP controls the switching system to reject the call of the calling user.

Step 190, verifying that the anti-disturbance key input by the calling user is correct, the SCP controls the switching system to connect the calling user's call to the selected terminal, and the calling party and the called party conduct a normal conversation.

In this way, the selected terminal of the user can further prevent some malicious and harassing calls from being answered, achieving the anti-disturbance function.

Of course, the above description is only the preferred embodiment of the present invention, and it should be pointed out that for those skilled in the art, some improvements and modifications can also be made without departing from the technical principles of the present invention. Retouching should also be regarded as the protection scope of the present invention.
