These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flow chart illustrating an information processing method according to an example embodiment. As shown in fig. 1, the information processing method may include the following steps:
in step 101, it is determined whether a second terminal in the wireless local area network has a tunnel direct connection channel TDLS transmission capability.
Specifically, the information processing method provided in this embodiment is applied to a first terminal that supports a transmission capability of a Tunnel Direct Link Setup (TDLS).
It should be explained that TDLS means that a secure, direct point-to-point interconnection can be created between two terminals supporting TDLS transmission capability in the wireless local area network. That is to say, a TDLS connection can be directly established between first terminals such as a mobile phone, a tablet computer, a television, a digital camera or a projector, which support TDLS transmission capability in the wireless local area network, to transmit information. Therefore, delay and interference caused by high transmission quantity of router load in the network are reduced, and transmission efficiency between terminals is improved.
Therefore, when the first terminal needs to transmit the screen information displayed by the terminal to the second terminal supporting the screen projection function in the wireless local area network through the TDLS, and display the screen information through the second terminal, whether the second terminal has the transmission capability of the TDLS, which is a tunnel direct connection channel, needs to be determined.
It should be noted that, according to a specific application scenario, it may be determined in multiple ways whether a second terminal in the wireless lan has a transmission capability of a tunnel direct connection channel TDLS, for example, as follows:
the first example specifically includes the following steps:
s1: sending a broadcast message carrying a TDLS transmission identifier to the wireless local area network;
s2: and if a response message which carries the TDLS transmission identification and is fed back by the second terminal according to the broadcast message is received, determining that the second terminal has the TDLS transmission capability.
Specifically, the first terminal sends a broadcast message carrying a TDLS transmission identifier to the wireless local area network, where the types of the broadcast message are many and may be selected according to application needs, and this embodiment does not limit this. Examples are as follows:
the types of broadcast messages may include: system broadcast messages, broadcast messages sent according to pre-negotiated protocols, broadcast messages sent using existing protocols, such as: broadcast messages sent over the MDNS protocol.
After other terminals in the wireless local area network receive the broadcast message which is sent by the first terminal and carries the TDLS transmission identifier, if the other terminals also have the TDLS transmission capability, a response message which carries the TDLS transmission identifier is fed back to the first terminal according to the broadcast message.
And if the first terminal receives a response message which carries the TDLS transmission identification and is fed back by the second terminal according to the broadcast message, determining that the second terminal has the TDLS transmission capability. And if the first terminal does not receive the response message which is fed back by the second terminal according to the broadcast message and carries the TDLS transmission identification, determining that the second terminal does not have the TDLS transmission capability.
The second example specifically includes the following steps:
s1: scanning broadcast messages sent by other terminals in the wireless local area network;
s2: and if the broadcast message carrying the TDLS transmission identifier sent by the second terminal is obtained, determining that the second terminal has TDLS transmission capability.
Specifically, the first terminal scans broadcast messages sent by other terminals in the wireless local area network. And judging whether the acquired broadcast message contains the broadcast message which is sent by the second terminal and carries the TDLS transmission identification.
If the first terminal acquires the broadcast message which is sent by the second terminal and carries the TDLS transmission identification, the second terminal is determined to have TDLS transmission capability; and if the first terminal does not acquire the broadcast message which is sent by the second terminal and carries the TDLS transmission identification, determining that the second terminal does not have the TDLS transmission capability.
The third example specifically includes the following steps:
s1: sending a TDLS transmission capability query request of the second terminal to a router of the wireless local area network;
s2: and if the TDLS transmission identification which is sent by the router and corresponds to the second terminal is obtained, determining that the second terminal has TDLS transmission capacity.
Specifically, the first terminal sends a TDLS transmission capability query request of the second terminal to the affiliated wireless local area network router. And after receiving the query request sent by the first terminal, the router queries the pre-stored terminal registration information supporting the transmission capability.
If the terminal registration information contains the second terminal, sending a TDLS transmission identifier corresponding to the second terminal to the first terminal; and if the terminal registration information does not contain the second terminal, sending a TDLS unsupported response message to the first terminal.
When the first terminal acquires the TDLS transmission identifier which is sent by the router and corresponds to the second terminal, the second terminal is determined to have TDLS transmission capability; and when the first terminal acquires that the TDLS sent by the router does not support the response message, determining that the second terminal does not have the TDLS transmission capability.
It should be noted that the above examples are only examples, and different manners may be selected to determine whether the second terminal has the transmission capability of the tunnel direct connection channel TDLS according to actual application situations.
In step 102, if it is determined that the second terminal has TDLS transmission capability, the TDLS is established with the second terminal.
Specifically, when the first terminal determines that the second terminal has the TDLS transmission capability, the TDLS transmission information supported by the second terminal is interacted with the first terminal through the router according to a preset TDLS protocol. The TDLS transmission information specifically includes: terminal identification, supported rate, and channel identification. And further, a TDLS connection is established between the first terminal and the second terminal.
In step 103, screen information is sent to the second terminal through the TDLS, so that the second terminal displays the screen information.
The first terminal sends the screen information to the second terminal through the TDLS between the first terminal and the second terminal, and the second terminal supporting screen projection displays the received screen information. For example:
the first terminal in the above embodiments may be a mobile phone, a tablet computer, a personal computer, or the like, and the second terminal in the above embodiments may be a television, a projector, or the like, which may be selected according to specific application requirements, which is not limited in this embodiment.
In summary, in the information processing method provided in this embodiment, if the first terminal determines that the second terminal in the wireless lan has the TDLS transmission capability, the TDLS is established with the second terminal, and the screen information is sent to the second terminal through the TDLS, so that the second terminal displays the screen information. The screen projection information is transmitted through the TDLS, the transmission efficiency of the screen projection information is improved, the diversity of transmission paths is expanded, and network blockage caused by overweight load of a router in traditional transmission is avoided.
Figure 2 is a flow chart illustrating an information processing method according to another exemplary embodiment,
as shown in fig. 2, for step 102 shown in fig. 1, several steps may be included as follows:
in step 201, if it is known that the second terminal is in a dormant state, the second terminal is awakened through the router of the wireless lan.
Specifically, if the first terminal learns that the second terminal is in the sleep state, the router of the wireless lan is instructed to wake up the second terminal. Therefore, the router sends the awakening instruction to the second terminal, and the second terminal is switched to a working state according to the awakening instruction so as to establish TDLS with the first terminal.
In step 202, a request message carrying TDLS transmission information is sent to the second terminal through the router of the wireless local area network.
Specifically, after the first terminal obtains the wakeup response sent by the router, it is known that the second terminal is currently in the working state. And further, sending a request message carrying the TDLS transmission information to the second terminal through a router of the wireless local area network.
Wherein the TDLS transmission information includes: terminal identification, supported rate, and channel identification. Therefore, the second terminal can acquire the transmission information of the first terminal requesting to establish the TDLS, and determine whether to agree with the establishment of the connection with the first terminal according to the transmission information.
In step 203, a TDLS setup response returned by the second terminal through the router is received.
In step 204, an acknowledgement is sent to the second terminal via the router.
Specifically, if the second terminal agrees to establish the TDLS connection with the first terminal, a TDLS setup response is returned to the router, and the router sends the TDLS setup response to the first terminal.
And then, after the first terminal receives the TDLS establishment response sent by the router, the first terminal sends confirmation information to the second terminal through the router. Thus, the first terminal establishes a TDLS connection with the second terminal, and the first terminal can transmit screen information to the second terminal through the TDLS.
In summary, in the information processing method provided in this embodiment, if the first terminal learns that the second terminal is in the dormant state, the router wakes up the second terminal, and then the TDLS is established with the second terminal through the router. The reliability of screen projection information transmission through TDLS is achieved, the transmission efficiency of the screen projection information is improved, the diversity of transmission paths is expanded, and network blockage caused by overweight load of a router in traditional transmission is avoided.
Figure 3 is a flow chart illustrating an information processing method according to another exemplary embodiment,
as shown in fig. 3, before step 102 of the above embodiment, the following steps may also be included:
in step 301, a first transmission distance to the second terminal is measured.
In particular, the first terminal measures a first transmission distance with the second terminal. The measurement mode of the first transmission distance is many, and can be selected according to application requirements, for example:
when the first terminal receives the broadcast message sent by the second terminal, the first transmission distance between the second terminal and the first terminal can be determined according to the signal strength of the broadcast message and the transmission power included in the broadcast message.
In step 302, a second transmission distance between a router through the wireless local area network and the second terminal is measured.
Specifically, the first terminal measures a second transmission distance between the router through the wireless local area network and the second terminal. The measurement mode of the second transmission distance is many, and can be selected according to the application requirement, for example:
the first terminal sends a first heartbeat signal to the router, and the distance between the first terminal and the router is determined according to the first heartbeat response signal returned by the router.
And the router determines the distance between the second terminal and the router according to a second heartbeat response signal returned by the second terminal.
And then, the first terminal determines a second transmission distance between the router of the first terminal and the second terminal according to the distance between the router of the first terminal and the router and the distance between the router of the second terminal and the second terminal.
In step 303, the first transmission distance and the second transmission distance are compared to determine an information transmission mode with the second terminal.
Specifically, the comparing, by the first terminal, the first transmission distance with the second transmission distance to determine the information transmission mode with the second terminal includes:
if the first terminal knows that the first transmission distance is less than or equal to the second transmission distance, the first terminal transmits information with the second terminal through TDLS;
and if the first terminal knows that the first transmission distance is greater than the second transmission distance, the first terminal transmits information with the second terminal through the router.
In summary, in the information processing method provided in this embodiment, the first terminal determines the information transmission manner with the second terminal by measuring the first transmission distance with the second terminal and measuring the second transmission distance between the router of the wireless local area network and the second terminal, and comparing the first transmission distance with the second transmission distance. The switching of the transmission paths of the screen projection information is realized, and the transmission efficiency of the screen projection information is improved.
