In the preparation stage, the technical scheme of the calling device of the embodiment of the invention is as follows:

the creating module 301 is configured to create the group. The creation module 301 is configured to set a password of the group, and to select a terminal number (or a custom terminal number) from a directory as a member of the group, and to set a group selection tone of the group.

The storage module 302 is used for storing the created group data to a predetermined storage space. Specifically, the storage module 302 is configured to call a relational database interface and store the group data in a database.

The configuration module 303 is configured to generate a configuration file corresponding to the group according to the data of the group. The configuration module 303 is configured to invoke a configuration file export script program, and generate the configuration file, where the configuration file includes information of each configured group (including a group authentication password, an audio file of a group selection prompt tone, and a group terminal number list).

The loading module 304 is configured to load the configuration file. The loading module 304 is further configured to create a group list according to the order of the groups in the configuration file, where the group list is a linked list (denoted as a first linked list), the group list includes at least one group, and each group corresponds to a terminal number table (denoted as a second linked list) that includes at least one terminal.

In the calling stage, the technical scheme of the calling device of the embodiment of the invention is as follows:

the transceiver module 305 is configured to receive conference initiation information sent by the first terminal.

Specifically, the transceiver module 305 receives first key input information sent by a first terminal, and acquires a key value corresponding to the first key input information according to a Dual Tone Multi Frequency (DTMF) algorithm.

The determining module 306 compares the key value with a key value corresponding to an operation of initiating a conference to determine whether the key value is consistent with the key value corresponding to the operation of initiating the conference, and may consider that the first terminal has made a request for initiating the conference if the key value is consistent with the key value corresponding to the operation of initiating the conference, where the first key input information is conference initiating information.

The transceiver module 305 may be embodied as a communication circuit of the calling device and the determination module 306 may be embodied as a processor of the calling device.

In a case where the first terminal makes a request for initiating a conference, the transceiver module 305 is further configured to send audio data including a group selection alert tone to the first terminal, so that the first terminal plays the group selection alert tone. The content of the group selection prompt tone includes information of a group and key information, for example, the content of the group selection prompt tone includes: group A, please press "1"; please press "2" for group B. The group selection tone may be previously generated or temporarily generated. In the embodiment of the present invention, the group refers to a set of terminals that can participate in a conference.

The creating module 301 or the configuring module 303 is configured to make the group selection warning tone in advance or temporarily make the group selection warning tone.

The transceiver module 305 is further configured to receive group selection information sent by the first terminal. The group selection information may be, for example, second key input information input by a user through the first terminal.

The judging module 306 is configured to judge whether the group is in a use state according to the use state identifier of the group corresponding to the group selection information, and generate a judgment result. For example, if the selected use status flag of the group is "used"/"occupied", the group is in a use status, and if the selected use status flag of the group is "unused"/"unoccupied", the group is in an unused status.

The transceiver module 305 is further configured to send a verification prompt to the first terminal when the group is in an unused state. The verification prompt message may be, for example, a prompt message for inputting a password, including: prompting the voice information or text information of the input password and triggering the first terminal to pop up the triggering information of the password input box.

The transceiver module 305 is further configured to receive feedback information corresponding to the verification prompt information sent by the first terminal. The feedback information may for example be password information entered by a user in the first terminal.

The call module 309 is further configured to join the second terminal that answered the call into a conference participant set (conference room). Specifically, the calling module 309 is configured to, when a first second terminal (the terminal that first answers the call in the terminal number table) appears, group the conference participant set (conference room) with the first terminal and the second terminal as members, and join a second terminal that subsequently answers the call into the conference participant set.

The setting module 307 is configured to set the use state identifier of the group corresponding to the group selection information when the verification result is that the verification is passed. In particular, the setting module 307 is configured to set the usage status flag to "used"/"occupied".

After the meeting is finished, the setting module 307 is configured to set the use state identifier of the group corresponding to the group selection information. Specifically, the use state flag is set to "unused"/"unoccupied".

The determining module 306 is further configured to determine whether a terminal corresponding to the terminal number information of the terminal number table has already joined the conference participant set, and generate a determination result. If the terminal has joined the conference participant set, the calling module 309 does not call the terminal any more.

The transceiver module 305 may or may not feed back the call result to the first terminal initiating the group invitation.

Referring to fig. 4 and 5, fig. 4 is a flowchart of a preparation phase of a calling method according to an embodiment of the present invention, and fig. 5 is a flowchart of an implementation phase of the calling method according to an embodiment of the present invention.

In the preparation stage 401, the technical solution of the calling method according to the embodiment of the present invention is as follows:

in step 4011, the creation module 301 creates the group. The creation module 301 sets a password of the group, and selects a terminal number (or a custom terminal number) from a directory as a member of the group, and sets a group selection tone of the group.

In step 4012, the storage module 302 stores the created group data into a predetermined storage space. Specifically, the storage module 302 calls a relational database interface and stores the group data in a database.

Step 4013, the configuration module 303 generates a configuration file corresponding to the group according to the data of the group. The configuration module 303 calls a configuration file export script program and generates the configuration file, wherein the configuration file comprises configured information of each group (including a group verification password, an audio file of a group selection prompt tone and a group terminal number list).

In step 4014, the loading module 304 loads the configuration file. The loading module 304 further creates a group list according to the order of the groups in the configuration file, where the group list is a linked list (denoted as a first linked list), the group list includes at least one group, and each group corresponds to a terminal number table (denoted as a second linked list) including at least one terminal.

In the calling phase 402 (implementation phase), the technical solution of the calling method of the embodiment of the present invention is as follows:

step 4021, the transceiver module 305 receives the conference initiation information sent by the first terminal.

Specifically, the transceiver module 305 receives first key input information sent by a first terminal, and obtains a key value corresponding to the first key input information according to a dual tone multi-frequency algorithm.

Step 4022, when the first terminal makes a request to initiate a conference, the transceiver module 305 sends the audio data including the group selection alert tone to the first terminal, so that the first terminal plays the group selection alert tone. The content of the group selection prompt tone includes information of a group and key information, for example, the content of the group selection prompt tone includes: group A, please press "1"; please press "2" for group B. The group selection tone may be previously generated or temporarily generated. In the embodiment of the present invention, the group refers to a set of terminals that can participate in a conference.

The creating module 301 or the configuring module 303 pre-makes the group selection warning tone or temporarily makes the group selection warning tone.

In step 4023, the transceiver module 305 receives the group selection information sent by the first terminal. The group selection information may be, for example, second key input information input by a user through the first terminal.

In step 4024, the determining module 306 determines whether the group is in a use state according to the use state identifier of the group corresponding to the group selection information, and generates a determination result. For example, if the selected use status flag of the group is "used"/"occupied", the group is in a use status, and if the selected use status flag of the group is "unused"/"unoccupied", the group is in an unused status.

Step 4025, the transceiver module 305 sends a verification prompt to the first terminal when the group is not in use. The verification prompt message may be, for example, a prompt message for inputting a password, including: prompting the voice information or text information of the input password and triggering the first terminal to pop up the triggering information of the password input box.

Step 4026, the transceiver module 305 receives the feedback information corresponding to the verification prompt information sent by the first terminal. The feedback information may for example be password information entered by a user in the first terminal.

In step 4027, the verification module 308 verifies the feedback information and preset information (preset password) and generates a verification result.

Step 4029, if the verification result is that the verification is passed, the calling module 309 reads the terminal number table of the group corresponding to the group selection information.

Step 40210, the calling module 309 calls the terminal corresponding to the terminal number information in the terminal number table.

In step 40211, the call module 309 joins the second terminal that answered the call to the conference participant set (conference room). Specifically, the calling module 309 establishes the conference participant set (conference room) with the first terminal and the second terminal as members when the first second terminal (the terminal that answers the call first in the terminal number table) appears, and joins the second terminal that subsequently answers the call into the conference participant set.

After step 4027, the method further comprises the steps of:

step 4028, if the verification result is that the verification is passed, the setting module 307 sets the use status identifier of the group corresponding to the group selection information. Specifically, the setting module 307 sets the usage status flag to "used"/"occupied". The purpose of setting the use status flag is to prevent the first terminal that is participating in the a conference from being joined to the conference participant set (conference room) of the B conference.

After the meeting is finished, the setting module 307 sets the use state identifier of the group corresponding to the group selection information. Specifically, the use state flag is set to "unused"/"unoccupied".

Prior to the step 40211, the method further comprises the steps of:

the determining module 306 determines whether the terminal corresponding to the terminal number information of the terminal number table is already added to the conference participant set, and generates a determination result. If the terminal has joined the conference participant set, the calling module 309 does not call the terminal any more.

The implementation scenarios of the calling device and method of the present invention are as follows:

the user accesses the Web server through client software, Web pages and the like, the Web server creates a group according to the operation of the user (including selecting an extension number (number of a terminal) from a telephone directory, adding the extension number as a member of the group to the group, or setting the extension number in a self-defined manner as a member of the group), sets a password of the group, sets a group selection prompt tone of the group and the like. Wherein the password is used for authentication to prevent the group from being used at will. The setting of the group selection alert tone of the group may be implemented by uploading an audio data file or selecting an alert tone from an alert tone list. The group selection prompt tone is used for identifying different groups for users.

The Web server calls a relational database interface to store data such as member information (including terminal numbers), passwords, group selection prompt tones and the like of the group in a database.

The Web server calls a group configuration file export script program to generate a group configuration file, wherein the group configuration file contains configured group information, and the group configuration file comprises the following steps: the password, the data file corresponding to the group selection prompt tone and each extension number in the group.

The telephone terminal (first terminal) enters the conference room by dialing the number of the conference room or by accepting the conference invitation of the Web server.

The telephone terminal generates first key input information according to the group function key input operation of the user and sends the first key input information to a number receiving module of the Web server.

And a number receiving module of the Web server acquires a key value according to the DTMF number receiving algorithm and transmits the key value to the conference module.

The conference module compares the received key value with the key value of the preset group function key, and starts the group voice navigation module when the two are matched.

The conference group voice navigation module sequentially plays group selection prompt tones to the telephone terminal according to the group linked list, a user of the telephone terminal identifies different groups according to the group selection prompt tones and simultaneously plays voices of corresponding number keys, wherein the voices of the number keys are used for the user to select corresponding groups, and the voices of the number keys are automatically generated according to the group sequence, if the number 1 corresponds to a first group, the number 2 corresponds to a second group, and so on).

The user of the telephone terminal inputs the corresponding number key according to the heard group selection prompt tone, the conference group voice navigation module receives the number key transmitted from the number receiving module, determines the corresponding group and checks the use state flag bit of the group, if the use state flag bit is not set, the authentication module of the Web server prompts the telephone terminal to input the password of the selected group, the telephone terminal inputs the password and is bound by a # number key, the number receiving module transmits the received password to the authentication module, and the authentication module compares the received password with the preset group password and prompts the password verification result (success or error).

When the password is successfully verified, the group use status flag bit is set to be used/in use, and the group calling module is called.

The authentication module comprises the verification module, namely, the verification module is a sub-module of the authentication module.

The group calling module obtains the extension number linked list from the selected group, sequentially calls each extension (terminal) according to the sequence of the extension numbers in the extension number linked list, if the extension numbers are in the conference room, the group calling module does not call any more, after the extension answers, the group calling module adds the extension to the conference room, and the calling result is not fed back to the telephone terminal initiating the conference.

And after the whole conference is finished, clearing the use state zone bit of the group.

The system comprises a Web server, a relational database, a conference group configuration file, a conference module, a number receiving module, a group voice navigation module, an authentication module and a group calling module, wherein the Web server, the relational database, the conference group configuration file, the conference module, the number receiving module, the group voice navigation module, the authentication module and the group calling module belong to components of the calling device.

In the above technical solution, after the transceiver module receives the group selection information, the calling module reads the terminal number table of the group corresponding to the group selection information, calls the terminal corresponding to the terminal number information in the terminal number table, and adds the second terminal answering the call to the conference participant set (conference room), at this time, the job of the user participating in the conference call is transferred from the conventional first terminal to the calling device of the embodiment of the present invention, that is, under the control (request) of the first terminal, the calling device of the embodiment of the present invention automatically calls (calls) the user to participate in the conference call without calling (calling) the conference participants one by one from the first terminal (caller) as in the conventional technical solution, so that the efficiency of the user participating in the conference call can be improved.
