Description

Method for establishing a communication connection

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a method for establishing communication connection.

Background

Qchat (a network talkback technology) is a talkback scheme based on EV-DO (short for Evolution, DataOnly, high data rate) network, and is a technology that can rapidly perform a "one-to-one" (also called single call) or "one-to-many" (including group call, chat room, etc.) call in the whole network by using a packet interactive network. The Qchat technology is widely applied to actual working scenes of personnel scheduling.

In the prior art, a dispatcher is equipped with a dispatching terminal and a first talkback terminal, and a dispatched person is equipped with a second talkback terminal. The talkback terminals (including the first talkback terminal and the second talkback terminal) are usually mobile phones, and after the talkback of the first talkback terminal and the second talkback terminal is connected, voice talkback can be performed between the dispatcher and the dispatched person. The scheduling terminal is usually a computer, which can open a web page version of the visual scheduling platform through a browser, and the scheduling platform provides functions of talkback calling, map positioning and the like. By utilizing the talkback calling function, the dispatcher can control the first talkback terminal to initiate talkback calling to the second talkback terminal of the dispatched person on the dispatching platform.

In order to implement the above-mentioned intercom call function, as shown in fig. 1, a first intercom terminal 11 is connected to a dispatch terminal 12 through a USB (Universal Serial Bus) data line 13. After the dispatcher selects the dispatched person needing to be called on the dispatching terminal 12, the dispatching terminal 12 sends a calling command to the first talkback terminal 11 through the USB data line 13, wherein the calling command carries the mobile phone number of the dispatched person needing to be called. After receiving the call command, the first intercom terminal 11 initiates a call request to the corresponding second intercom terminal 14 according to the mobile phone number of the dispatched person to be called, and after the second intercom terminal 14 is put through intercom, voice intercom can be performed at both ends.

The mode that the first talkback terminal and the scheduling terminal are connected by the USB data line adopted by the prior art has the following problems: firstly, when in use, a user needs to install a driver, set a port and the like in a scheduling terminal, and the operation is complex; secondly, performing secondary drying; and the user cannot flexibly move the first talkback terminal due to the limitation of the length of the USB data line.

Please refer to fig. 2, which illustrates a schematic diagram of a possible application scenario provided by the embodiment of the present invention. The application scenario includes: a first intercom terminal 21, at least one second intercom terminal 22, a scheduling terminal 23 and a server 24.

The talkback terminals (including the first talkback terminal 21 and the second talkback terminal 22) refer to terminals having a talkback function, such as a mobile phone. The first intercom terminal 21 refers to an intercom terminal used by the dispatcher. The second intercom terminal 22 refers to an intercom terminal used by the dispatcher, and the number of the second intercom terminals 22 is usually plural. The talkback terminal is provided with a talkback client, and the talkback client is used for realizing the talkback function. In the embodiment of the present invention, it is assumed that the intercom client installed in the first intercom terminal 21 is a first intercom client, and the intercom client installed in the second intercom terminal 22 is a second intercom client. In the method embodiment described below, the execution subject "intercom client" refers to an intercom client installed in the first intercom terminal 21, that is, the first intercom client.

The scheduling terminal 23 is typically a PC (Personal Computer), or other display device. The dispatch terminal 23 is also available to the dispatcher who can open and run the visual dispatch platform. The scheduling terminal 23 has a scheduling station client installed therein. In general, the visual scheduling platform is implemented in a form of a Web page, and accordingly, the scheduling platform client is a browser capable of opening the visual scheduling platform in the form of the Web page (referred to as a Web scheduling platform). Of course, in other possible implementations, the visualization scheduling platform may also be implemented in the form of an application program, and the visualization scheduling platform includes a client and a server that provides a background service for the client, where the client may be referred to as a scheduling platform client.

The server 24 is used for providing background services for the talkback client and the dispatcher station client. The server 24 mainly provides two services: (1) providing related services of the talkback function, such as establishing communication connection required by talkback, forwarding voice data, collecting personnel state information and the like; (2) and related services of a visual dispatching platform are provided, such as initiating an intercom call, tracking and positioning dispatched personnel, displaying the geographic position of the dispatched personnel and the like. In practical implementation, the server 24 may be a server, a server cluster composed of multiple servers, or a cloud computing service center. When the server 24 is a cluster architecture, it may include an intercom server and a dispatcher station server, where the intercom server is used for implementing the function described in the above (1), and the dispatcher station server is used for implementing the function described in the above (2).

In addition, each of the talkback terminals (including the first talkback terminal 21 and the second talkback terminal 22) and the scheduling terminal 23 has a communication connection with the server 24, and the communication connection may be a wireless network connection.

In one example, the application scenario shown in fig. 2 is a Qchat intercom system integrated with a visual scheduling platform.

In order to solve the problem caused by the connection of the first talkback terminal and the scheduling terminal through the USB data line in the prior art, the scheme provided by the embodiment of the invention realizes the establishment of the communication connection between the first talkback terminal and the scheduling terminal through the wireless network. The embodiments of the present invention will be described in further detail below based on the common aspects related to the embodiments of the present invention described above.

Referring to fig. 3, a flowchart of a method for establishing a communication connection according to an embodiment of the present invention is shown. The method can be applied to the application scenario shown in fig. 2. The method may include several steps as follows.

Step 301, the dispatcher station client sends a first connection establishment request to the server.

The first connection establishment request requests establishment of a first wireless communication connection with a server. The first connection establishing request carries a target user account which logs in the dispatching desk client. The user account may be a user name, a mobile phone number, or the like, and may be used to uniquely identify a user.

Step 302, the server establishes a first wireless communication connection with the dispatcher station client according to the first connection establishment request.

And after receiving the first connection establishment request sent by the dispatching desk client, the server establishes a first wireless communication connection with the dispatching desk client. Optionally, the first wireless communication connection is a WebSocket connection. The WebSocket Protocol is a full-duplex (full-duplex) communication Protocol based on a Transmission Control Protocol (TCP), which realizes full-duplex communication between a client and a server, i.e., allows the server to actively send information to the client, and avoids the problems of terminal power consumption and flow consumption caused by acquiring data from the server in a client polling server manner.

In addition, the server records the corresponding relation between the target user account and the connection information of the first wireless communication connection. Wherein the connection information of the first wireless communication connection comprises an identification of the first wireless communication connection.

Step 303, the intercom client sends a second connection establishment request to the server.

The second connection establishment request is for requesting establishment of a second wireless communication connection with the server. The second connection establishment request carries a target user account logged in to the talkback client.

And step 304, the server establishes a second wireless communication connection with the talkback client according to the second connection establishment request.

And after receiving a second connection establishment request sent by the talkback client, the server establishes a second wireless communication connection with the talkback client. Optionally, the second wireless communication connection is a WebSocket connection.

In addition, the server records the corresponding relation between the target user account and the connection information of the second wireless communication connection. Wherein the connection information of the second wireless communication connection comprises an identification of the second wireless communication connection.

The dispatcher station client communicates with the intercom client over the first wireless communication connection and the second wireless communication connection, step 305.

After the first wireless communication connection and the second wireless communication connection are established, the dispatcher station client and the talkback client establish wireless communication connection through the server, and the dispatcher station client can communicate through the wireless communication connection, for example, the dispatcher station client sends a call command to the talkback client through the wireless communication connection.

It should be noted that, in the embodiment of the present invention, the execution order of the steps 301 and 303 is not limited, and the step 301 may be executed before the step 303, may be executed after the step 303, or may be executed simultaneously with the step 303.

In summary, in the solution provided in the embodiment of the present invention, the wireless communication connection is established between the dispatching desk client and the intercom client through the server, so as to overcome the problems of the USB data line connection, on one hand, operations such as installing a driver and setting a port are not required to be performed, and user operations are simplified; on the other hand, the intercom terminal can be flexibly moved.

Referring to fig. 4, a flowchart of a method for establishing a communication connection according to another embodiment of the present invention is shown. The method can be applied to the application scenario shown in fig. 2. The method may include several steps as follows.

Step 401, the dispatcher station client sends a first connection establishment request to the server.

Optionally, the first connection establishment request carries a target user account and a client type logged in to the dispatcher station client. In the embodiment of the invention, the client types comprise two types, namely a dispatcher client and an intercom client. The client type carried in the first connection establishment request sent by the dispatching desk client to the server is the dispatching desk client.

In an example, assuming that the user name logged in to the dispatcher station client is UserName _1, the first connection establishment request carries the UserName _1 and the WebClient (indicating that the client type is the dispatcher station client).

Step 402, the server establishes a first wireless communication connection with the dispatcher station client according to the first connection establishment request.

Optionally, the server establishes a WebSocket connection with the dispatcher station client according to the first connection establishment request.

In step 403, the server adds the corresponding relationship between the target user account and the connection information of the first wireless communication connection in the first connection pool.

The first connection pool is used for recording wireless communication connection established by the server and each dispatching desk client. For example, the server stores a correspondence between a destination user account and connection information of the first wireless communication connection in a form of a Key-Value pair (Key-Value) in the first connection pool, where the destination user account is used as a Key and the connection information of the first wireless communication connection is used as a Value. In one example, assuming that the connection information for the first wireless communication connection is represented by WebConnection _1, the server stores key-value pairs of the form: < UserName _1, WebConnection _1>, wherein UserName _1 is used as Key and WebConnection _1 is used as Value. In addition, in the embodiment of the present invention, the connection information of the first wireless communication connection may include information such as an identifier and a status of the first wireless communication connection.

Illustratively, the first connection pool includes key-value pairs as shown in the following Table-1:

UserName_1	WebConnection_1
		UserName_2	WebConnection_2
…	…
		UserName_N	WebConnection_N

TABLE-1

Step 404, the intercom client sends a second connection establishment request to the server.

Optionally, the second connection establishment request carries a target user account and a client type logged in to the intercom client. And the type of the client carried in the second connection establishment request sent by the talkback client to the server is the talkback client.

In an example, assuming that the user name logged into the intercom client is UserName _1, the second connection establishment request carries UserName _2 and AppClient (indicating that the client type is the intercom client).

In step 405, the server establishes a second wireless communication connection with the intercom client according to the second connection establishment request.

Optionally, the server establishes a WebSocket connection with the talk-back client according to the second connection establishment request.

In step 406, the server adds the corresponding relationship between the target user account and the connection information of the second wireless communication connection in the second connection pool.

And the second connection pool is used for recording the wireless communication connection established between the server and each talkback client. For example, the server stores a correspondence between the target user account and connection information of the second wireless communication connection in a form of a Key-Value pair (Key-Value) in the second connection pool, where the target user account is used as a Key and the connection information of the second wireless communication connection is used as a Value. In one example, assuming that the connection information of the second wireless communication connection is represented by AppConnection _1, the server stores a key-value pair of the form: < UserName _1, AppConnection _1>, wherein UserName _1 is used as Key and AppConnection _1 is used as Value. In addition, in the embodiment of the present invention, the connection information of the second wireless communication connection may include information such as an identification and a status of the second wireless communication connection.

Illustratively, the second connection pool includes key-value pairs as shown in the following table-2:

UserName_1	AppConnection_1
		UserName_2	AppConnection_2
…	…
		UserName_N	AppConnection_N

TABLE-2

After the first wireless communication connection and the second wireless communication connection are established, the dispatcher station client and the talkback client can communicate through the wireless communication connection, namely the wireless communication connection is established between the dispatcher station client and the talkback client through the server. Next, the related procedures of the call command transmission and the personnel status information feedback are described through steps 407 and 412.

In step 407, the dispatcher station client sends a first call command to the server through the first wireless communication connection after determining the dispatched person who needs to call.

The first call command includes: the system comprises a target user account and personnel information, wherein the personnel information is used for indicating the dispatched personnel needing to be called. The first calling command is used for indicating the talkback client corresponding to the dispatcher to initiate calling to the talkback client corresponding to the dispatched personnel needing calling according to the personnel information. Optionally, the staff information includes an identifier of each scheduled staff needing to be called, such as a mobile phone number, a user name, and the like.

The types of the talkback call include a single call and a group call, wherein the single call is directed to one dispatched person to initiate a call, and the group call is directed to a plurality of dispatched persons to initiate a call simultaneously. In one example, the types of intercom calls include a single call, a temporary group call, and a predefined group call. The temporary group call is to initiate a call to a plurality of scheduled persons in the temporarily created group, and the predefined group call is to initiate a call to a plurality of scheduled persons in the pre-created group.

Optionally, the type of the intercom call is also included in the first call command. When the type of the talkback call is a single call or a temporary group call, the personnel information comprises the identification (such as a mobile phone number or a user name) of each dispatched personnel; when the type of the intercom call is a predefined group call, the person information comprises a group identification of the predefined group.

Optionally, the first call command further includes a message-to-destination parameter, where the message-to-destination parameter is used to indicate a recipient of the message. For example, if the receiver of the first call command is the talkback client corresponding to the dispatcher, the message forwarding parameter is the talkback client.

Optionally, the first call command further includes a message type parameter, where the message type parameter is used to indicate a type of the message. For example, the message types include different types such as originating a call, feeding back personnel status information, and the like. And the message type parameter carried in the first call command is used for indicating the call initiation.

Optionally, the dispatcher station client uses the following two possible implementations to determine the dispatched person to call. The display interface of the dispatching desk client comprises a map area and a non-map area. The map area is used for displaying a map in which the geographical position information of each scheduled person can be marked. And a personnel list is displayed in the non-map area, and the personnel list comprises relevant information of each dispatched personnel, such as a user name, a mobile phone number and the like. In one possible implementation manner, the dispatching desk client acquires a selection signal corresponding to one or more dispatched persons in the person list, and determines dispatched persons needing to be called according to the selection signal. In another possible implementation manner, the dispatching desk client acquires a framing signal corresponding to a target area in the map area, and determines dispatched persons located in the target area as dispatched persons needing to be called.

In step 408, the server sends a second call command to the intercom client through the second wireless communication connection, in case that it is determined that the second wireless communication connection corresponding to the target user account is already established.

After receiving a first call command sent by a dispatching desk client, a server analyzes parameters carried in the first call command, such as a message destination parameter, a target user account (such as UserName _1), a message type parameter and personnel information (such as a mobile phone number of a dispatched person needing to be called). If the message destination parameter indicates the talkback client, the server searches whether a second wireless communication connection corresponding to the target user account exists in a second connection pool, and if the second wireless communication connection exists, the server sends a second call command to the talkback client through the second wireless communication connection according to the connection information of the second wireless communication connection.

The second calling command carries personnel information used for indicating dispatched personnel needing to call, and the second calling command is used for indicating the talkback client to initiate a call to the dispatched personnel. Optionally, the second call command further includes a type of the intercom call. Optionally, the second call command further includes a message type parameter, and the message type parameter carried in the second call command is used to indicate that a call is initiated.

In addition, if the server does not find the second wireless communication connection corresponding to the target user account in the second connection pool, the server sends a prompt message to the dispatching desk client through the first wireless communication connection, wherein the prompt message is used for prompting that the connection cannot be established, and asking the user to check whether the target user account is logged in the talkback client.

And step 409, the talkback client sends a call request to the talkback client corresponding to the dispatched personnel according to the personnel information.

The calling request is used for requesting the talkback client corresponding to the dispatched personnel to connect talkback.

And after the talkback client corresponding to the dispatcher receives the second call command, analyzing the second call command to obtain the type and personnel information of the talkback call. If the type of the talkback call is a single call or a temporary group call, directly extracting the identifier of each dispatched person from the person information; and if the type of the talkback call is the predefined group call, extracting the group identification of the predefined group from the personnel information, and inquiring and acquiring the identification of each dispatched personnel in the predefined group according to the group identification. And then, the talkback client sends a call request to the talkback client corresponding to each dispatched person according to the identification (such as the mobile phone number) of each dispatched person.

Optionally, if the second call command includes an identifier (e.g., a mobile phone number) of each scheduled person, the talkback client corresponding to the scheduler directly sends a call request to the talkback client corresponding to the scheduled person according to the identifier.

And step 410, after the talkback is connected, the talkback client acquires the personnel state information.

The personnel state information is used for indicating the state of the personnel participating in the talkback. Optionally, the personnel status information comprises at least one of: the total number of people participating in the conversation, the number of people who are connected to the conversation, the identification of the person who currently has the right to speak (i.e., is currently speaking). Optionally, the person status information further includes an identifier of each person participating in the intercom. The personnel participating in the talkback comprise a dispatcher and each dispatched personnel needing to be called.

One point to be explained is that, for a single-call scenario, as one dispatched person needing to be called is, the dispatched person turns on the talkback and then considers that the talkback is turned on; for a temporary group call or a predefined group call scenario, as a plurality of scheduled persons needing to be called are available, as long as at least one scheduled person is connected to talk, the talk-back is considered to be connected.

In one example, assuming that the dispatcher initiates a temporary group call, the number of dispatched persons who need to call is 5 (zhang san, li yi, wang wu, zhao xi and sun qin, respectively), wherein zhang san, li yi, wang wu and zhao liu are put through with the dispatcher for talkback, sun qin is not put through for talkback, and zhang san currently has the talk right, the total number of persons participating in talkback is 6, the number of persons who put through talkback is 5, and the mobile phone number of the person currently having the talk right is identified as zhang san.

Step 411, the intercom client sends the personnel status information to the server through the second wireless communication connection.

Optionally, the intercom client sends an information feedback message to the server through the second wireless communication connection, where the information feedback message includes: a message destination parameter (e.g., dispatcher client), a target user account (e.g., UserName _1), a message type parameter, and personnel status information.

Optionally, after receiving the person state information, the server queries and acquires the geographical location information of the person participating in the talkback from the database according to the identifier of the person participating in the talkback. The database is used for recording the geographic position information of each person, including the geographic position information of the dispatcher and each dispatched person. In one example, the database records the correspondence between the identification of each person and the geographical location information.

Optionally, the server receives a position reporting request sent by each talkback client at a preset time interval, the position reporting request carries the identification and the geographical location information of the personnel corresponding to the talkback client, and then the server correspondingly stores the identification and the geographical location information of the personnel in the database. The preset time interval may be set to 10 seconds, 30 seconds, 1 minute, 5 minutes, and the like, which is not limited in the embodiment of the present invention.

In an embodiment of the invention, the geographical location information comprises longitude and latitude coordinates. Optionally, the geographic location information further includes a location name corresponding to the longitude and latitude coordinate, such as xx school, xx cell, xx hospital, and the like.

In step 412, the server forwards the personnel status information to the dispatcher station client via the first wireless communication connection.

Optionally, the server sends the information feedback message to the dispatcher station client through the first wireless communication connection. Optionally, the information feedback message further includes geographic location information of the person participating in the talk-back.

And after receiving the information feedback message, the dispatching desk client extracts various information from the information feedback message and displays the information correspondingly. Optionally, the dispatcher station client displays the personnel status information and the geographical location information of the personnel participating in the talkback in the same user interface. As already described above, a map region and a non-map region are included in the user interface. The dispatching desk client displays the personnel state information in a non-map area of the user interface, and marks the geographic position of the personnel participating in the talkback in the map area of the user interface according to the geographic position information of the personnel participating in the talkback. In one possible implementation manner, the client of the dispatching desk displays marks of the persons participating in the talkback at corresponding positions of a map area of a user interface according to the geographical position information of the persons participating in the talkback, wherein the marks of the persons having the speaking right currently are displayed in a mode of being different from the marks of other persons participating in the talkback. The manner of displaying the mark differently is not limited in the embodiments of the present invention, and examples include color, style, shape, content, whether it is a dynamic icon, and the like.

It should be noted that, in the embodiment of the present invention, the execution order of the steps 401 and 404 is not limited, and the step 401 may be executed before the step 404, may be executed after the step 404, or may be executed simultaneously with the step 404.

In addition, in the scheme provided by the embodiment of the invention, the WebSocket connection is established between the client (including the dispatching desk client and the talkback client) and the server, so that full-duplex communication between the client and the server is realized, namely, the server is allowed to actively send information to the client, and the problems of terminal electricity consumption, flow and the like caused by the adoption of a client polling server mode to obtain data from the server are avoided.

In addition, in the scheme provided by the embodiment of the invention, the integration of the talkback calling function and the map positioning function is realized, and after the dispatcher initiates the talkback call, the geographical position distribution of each person participating in talkback, the latest geographical position of the person who is talking at present and other information can be checked on the map in real time, so that the visual dispatching of the dispatcher is better facilitated.
