The embodiments of the present invention, and all other embodiments obtained by a person of ordinary skill in the art without any inventive work, belong to the scope of protection of the present invention.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Example 1
Referring to fig. 2-3, in this embodiment, a method for implementing face-to-face exchange of electronic business cards is provided, which can implement exchange of electronic business cards without or with a network, and includes:
step S101: the first terminal starts the multimedia Connectivity, receives a polling request sent by a second terminal which also starts the multimedia Connectivity nearby, and under the condition of no network, the first terminal responds to the polling request sent by the second terminal and establishes a Connection with the second terminal. The business card exchange process between the first terminal and the second terminal is described in detail later in the following text when the network is clear.
Step S102: the first terminal receives a second business card exchange request sent by a second terminal nearby;
step S103: the first terminal detects whether a second terminal approaches within a preset distance through a distance sensor,
if yes, responding to a second business card exchange request of a second terminal, and the method comprises the following steps:
sending confirmation information and the first electronic business card to the second terminal;
and receiving a second electronic business card sent by a second terminal.
If not, the second exchange business card request sent by the second terminal is not responded.
In step S101, the multicast Connectivity is implemented by a Multicast Connectivity Framework (MCF) built in the application, where the MCF is a Framework for nearby devices to communicate via a WiFi network and a bluetooth personal area network, and the interconnected nodes can securely transmit information, streams, or other file resources without using network services.
In step S101, the first terminal and the second terminal establish a Connection with a precondition: the first terminal and the second terminal need to be in the same "network" environment. For example, the first terminal and the second terminal both access the wide area network through WiFi or 4G/5G network, or both the first terminal and the second terminal turn on WiFi or bluetooth and connect with each other through WiFi or bluetooth.
The first terminal and the second terminal cannot establish Connection if the first terminal and the second terminal are in the following states:
both do not have access to the wireless wide area network and the MCF;
one party accesses the wireless wide area network and the other party accesses the MCF, or one party accesses the MCF and the other party accesses the wireless wide area network;
one party has access to the wireless wide area network or MCF, while the other party has no access to the wireless wide area network or MCF.
When any one of the above situations occurs, the first terminal and/or the second terminal prompts access to the wireless wide area network or the MCF at an application layer of the terminal device. In order to obtain the best experience and avoid the situation that multiple network types are not matched, when the first terminal and the second terminal start the multi Connectivity, WiFi or Bluetooth of the terminals are uniformly started, and communication connection between the first terminal and the second terminal is achieved by using MCF.
In this embodiment, the second terminal serves as an initiator, and when the second terminal enables a multi Connectivity, the second terminal searches for a nearby first terminal and polls the found first terminal. And simultaneously, the second terminal can monitor the state of the distance sensor, detect whether a first terminal approaches within a preset distance through the distance sensor, and trigger the second terminal to send a second business card exchange request to the first terminal if the first terminal approaches.
The first terminal serves as a receiver, after receiving a second exchange request sent by a second terminal, the first terminal can detect whether the second terminal approaches within a preset distance through a built-in distance sensor, if so, the first terminal indicates that the second terminal approaches the first terminal and initiates a business card exchange action to the second terminal, and at the moment, the first terminal responds to the second exchange request of the second terminal and sends confirmation information and the first electronic business card to the second terminal through an MCF channel.
And after receiving the determination information sent by the first terminal, the second terminal sends the first electronic business card of the second terminal to the first terminal through the MCF channel.
And after receiving the electronic business card of the other party, the first terminal and the second terminal display the electronic business card of the other party on respective application programs, and thus, the exchange work is finished.
In the embodiment of the invention, the two terminal devices can automatically complete the exchange of the electronic business cards only by closing each other after the multiperer Connectivity is started, and the exchange can be carried out even under the condition of no network, thereby greatly optimizing the experience of exchanging the electronic business cards on occasions of online users.
Alternatively, in step S101, when the first terminal enables the multi Connectivity, a preparation state for sending the electronic business card will be entered at the same time. Likewise, when the second terminal enables the MultiPeerConnectivity, the second terminal will also enter a preparation state for sending electronic business cards. From this, after confirming that first terminal and second terminal are close to each other, first terminal and second terminal can directly get into the business card exchange flow, need not the user and carry out loaded down with trivial details operation, and the process of business card exchange is more succinct, laminates the real business card exchange action.
Optionally, in step S103, detecting whether a second terminal approaches within a predetermined distance by a distance sensor includes:
monitoring the state of a distance sensor of a first terminal, and generating a sensing signal corresponding to a second terminal when the distance sensor detects that the second terminal approaches, wherein the sensing signal comprises the position of the second terminal;
comparing the position information of the first terminal with the position information of the second terminal, determining the distance between the first terminal and the second terminal, and detecting whether the distance between the first terminal and the second terminal is within a preset distance.
Preferably, the sensing signal further includes a second timestamp detected by the second terminal, the second exchange business card request carries the first timestamp, and in step S103, before responding to the second exchange business card request of the second terminal, the method further includes: and comparing the first time stamp with the second time stamp, determining the time interval between the first time stamp and the second time stamp, and judging whether the time interval is smaller than a set value.
Therefore, whether the time when the first terminal receives the second exchange business card is close to the time when the first terminal senses the second terminal is judged, for example, the time interval is less than 5 seconds (which is equivalent to a set value of 5 seconds), and when the time interval is less than 5 seconds, the second terminal close to the first terminal simultaneously initiates a second exchange business card request to the first terminal, so that the second exchange business card request sent by the second terminal can be responded. Otherwise, the second terminal sending the second business card exchange request and the second terminal close to the first terminal are not the same terminal equipment, and the second business card exchange request is not responded.
Meanwhile, in order to ensure that the first terminal is in the receiving state of the business card, in this embodiment, the method further includes, before detecting whether the second terminal is close to the first terminal within a predetermined distance by the distance sensor:
detecting whether an application program of which the first terminal starts the multipher Connectivity runs in the foreground of the first terminal, and when the application program runs in the foreground of the first terminal, detecting whether a second terminal approaches within a preset distance through a distance sensor, otherwise, not responding to a second business card exchange request.
As shown in fig. 4, in step S101, if the first terminal and the second terminal both access the same wireless wide area network, that is, in the presence of a network, the first terminal sends its location information, a first electronic business card and a first business card exchange request to the server, and the second terminal sends its location information, a second electronic business card and a second business card exchange request to the server; the server analyzes timestamps in the first exchange business card request and the second exchange business card request, the timestamps of the two requests are compared, whether the two timestamps are close or not is judged, whether position information uploaded by the first terminal and position information uploaded by the second terminal are close or not is judged if the two timestamps are close, the second electronic business card is issued to the first terminal if the two timestamps are close or not, the first electronic business card is issued to the second terminal, the electronic business card of the other side is displayed on respective application programs after the first terminal and the second terminal receive the electronic business card of the other side, and therefore the exchange work is completed.
Example 2
Referring to fig. 5, the present invention provides a face-to-face electronic business card exchange method, which includes:
step S201: the method comprises the steps that a first terminal starts a multipath Connection, receives a polling request sent by a second terminal which starts the multipath Connection nearby, and responds to the polling request sent by the second terminal and establishes a Connection with the second terminal;
step S202: the first terminal receives a second business card exchange request sent by a second terminal nearby, and sends a first business card exchange request to the second terminal, namely the first terminal and the second terminal mutually send business card exchange requests to each other after Connection is established.
Step S203: the first terminal detects whether a second terminal approaches to the first terminal within a preset distance through a distance sensor, and if so, responds to a second business card exchange request of the second terminal, and the method comprises the following steps:
sending confirmation information and the first electronic business card to the second terminal;
and receiving a second electronic business card sent by a second terminal.
In this embodiment, the specific implementation manner of step S201 is the same as that of step S101 in embodiment 1, and details are not repeated again.
In step S202, the first terminal defaults to be the receiving side, the second terminal defaults to be the originating side, and the exchange flow of the business card defaults to be the originating side of the second terminal.
If the second terminal receives the first business card exchanging request sent by the first terminal after sending the second business card exchanging request, the second terminal returns a notice to the first terminal, which indicates that the exchanging process is initiated. After receiving the notification, the first terminal executes step S203.
If the second terminal receives the first business card exchanging request sent by the first terminal before sending the second business card exchanging request, the second business card exchanging request sent to the first terminal is stopped, and the second terminal enters the business card exchanging action. And if the first business card exchange request of the first terminal exists, responding to the first business card exchange request of the first terminal, and sending confirmation information and the first electronic business card to the first terminal through an MCF channel. And after receiving the determination information sent by the first terminal, the second terminal sends the second electronic business card to the first terminal through the MCF channel. And after receiving the electronic business card of the other party, the first terminal and the second terminal display the electronic business card of the other party on respective application programs, and thus, the exchange work is finished.
In the embodiment of the invention, users can mutually send business card exchange requests through terminal equipment, when a user serving as an initiator receives the business card exchange request sent by the opposite side before sending the business card exchange request, the terminal equipment can automatically terminate the request sending behavior and parallelly convert the request sending behavior into a receiving side to respond to the business card exchange request of the opposite side without waiting for the response of the terminal equipment of the opposite side all the time, so that the business card exchange process is smoother. When the user as the initiator receives the business card exchange request sent by the opposite side after sending the business card exchange request, a notice can be returned to the business card exchange request sent by the opposite side user to indicate that the exchange process is initiated. Therefore, redundant communication behaviors between the two users are effectively avoided, and unnecessary resource consumption is generated.
