In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The intelligent terminal of the embodiment of the invention can exist in various forms, and the intelligent terminal comprises but is not limited to:
(1) a mobile communication device: such devices are characterized by mobile communications capabilities and are primarily targeted at providing voice, data communications. Such terminals include smart phones (e.g., iphones), multimedia phones, etc.

Example 1:
embodiment 1 of the present invention provides a method for implementing screen projection of a convergence terminal, where an intelligent terminal is connected to a WIFI network using a first convergence terminal as a signal source, and as shown in fig. 1, the method includes:
in step 201, a device identifier of a designated convergence terminal to be accessed to a screen projection is obtained, and a first request message is sent to the first convergence terminal. For example: the first request message may appear as an HTTP request message specifying a URL.
Wherein, the first request message carries the device identifier of the appointed convergence terminal. In an actual scene, one of the most direct expression forms of the device identifier is an MAC address, and in addition, a unique ID number may be pre-assigned by each convergence terminal, for example, the device identifier may be an identifier number set by the convergence terminal when the convergence terminal leaves a factory, and is mainly used as a unique identifier for each convergence terminal.
The designated convergence terminal to be accessed to the screen projection is generally a convergence terminal in a room where a user holds an intelligent terminal in the hotel scene provided by the embodiment of the invention. For example: when a user holds a smart phone in a bag house 101, the corresponding designated convergence terminal to be accessed to screen projection refers in particular to the convergence terminal set in the bag house 101.
In step 202, the first convergence terminal receives the first request message, and confirms that the device identifier of the designated convergence terminal carried in the first request message matches with the device identifier of the first convergence terminal (the technology meaning represented here is that the designated convergence terminal and the first convergence terminal are the same device), and then the first convergence terminal establishes a screen-casting link with the intelligent terminal through a screen-casting protocol.
The screen projection link established with the intelligent terminal can be a first fusion terminal, namely the fusion terminal in the embodiment of the invention can further be fused with a screen projection function; besides, the screen projecting device may be an independent screen projecting device, and certainly, after the matching confirmation in step 202, the corresponding screen projecting device and the intelligent terminal are both in the WIFI network established by the first convergence terminal, so that the establishment of the corresponding screen projecting link may be completed through the existing screen projecting protocol including DLNA, airplay, Miracast, and the like.
According to the embodiment of the invention, through a calibration method under WIFI network connection, an intelligent terminal can find and finally connect to a target fusion terminal to realize screen projection service in a plurality of fusion terminal environments by using the iteration mode provided by the embodiment of the invention; the situation that similar hotel application scenes are connected through a network due to the WIFI homonymous SSID can be effectively avoided, the situation that the network is connected with a fusion terminal of other rooms, screen projection to other rooms is caused, and the risk of data privacy disclosure of users appears.
As an implementation scheme of the present invention, in step 202, in addition to the above conclusion of matching the identifiers of the devices, a judgment branch that the identifiers of the devices are not matched is further included, which means that the designated convergence terminal and the first convergence terminal are not the same device, that is, in the hotel scene, the convergence terminal that is established with the WIFI network connection by the intelligent terminal and the convergence terminal in the room where the current user is located are not the same device. As shown in fig. 2, if it is determined that the device identifier of the designated convergence terminal carried in the first request message is not matched with the device identifier of the designated convergence terminal, the method further includes:
in step 203, the first convergence terminal actively disconnects the WIFI network connection with the intelligent terminal, and sets in a time-limited manner that the intelligent terminal cannot reconnect the first convergence terminal.
The time limit setting is obtained by calculating the number of the fusion terminals which can be detected by the intelligent terminal as WIFI signal sources under the current scene and the average time required by each fusion terminal to complete one round of equipment identification matching. Therefore, through the time limit setting, the fusion terminal which is initially disconnected from the intelligent terminal WIFI network can be allowed to complete the MAC address matching process of all the fusion terminals within the effective WIFI signal strength detection range within the time limit. The MAC address matching process of all the converged terminals in the detection range can be represented by establishing WIFI network connection- > matching the device identifiers- > disconnecting the WIFI network connection if not matching- > reestablishing new WIFI network connection- > reestablishing device identifiers- > continuing disconnecting the WIFI network connection if not matching in the specific implementation process, and the WIFI network connection and the corresponding device identifier matching between all the converged terminals in the detection range are iteratively completed by the aid of the method until the matching is successful or the matching process of the corresponding device identifiers of the converged terminals in all the corresponding detection ranges is completed. In addition, in an optimal scheme, when each convergence terminal is initially arranged in a scene (e.g., a hotel), different SSIDs of each convergence terminal are set, and a round of WIFI network connection is established with each convergence terminal one by one in advance by using an intelligent terminal, so that the time-limited set calculation process can be completed by entering a corresponding WIFI network environment again based on a signal source of the intelligent terminal for a historically connected WIFI network.
In step 204, after the intelligent terminal disconnects the WIFI network connection with the first convergence terminal, the intelligent terminal actively establishes WIFI network connection with other convergence terminals; and after the intelligent terminal establishes WIFI network connection with a second convergence terminal, sending a second request message to the second convergence terminal.
After the intelligent terminal is disconnected from the WIFI network of the first convergence terminal, the intelligent terminal actively establishes WIFI network connection with other convergence terminals, and in the implementation process of the embodiment of the invention, an optimal technology is also provided, and the second convergence terminal and the first convergence terminal use the same SSID and password, so that after the intelligent terminal is disconnected from the WIFI network of the first convergence terminal, the intelligent terminal can establish WIFI network connection with the second convergence terminal according to history related information (the SSID and the password) of the WIFI network connected to the first convergence terminal.
In step 205, the second convergence terminal confirms that the device identifier of the designated convergence terminal carried in the second request message matches with the device identifier of the second convergence terminal (the represented technical meaning is that the designated convergence terminal and the second convergence terminal are the same device), and then the second convergence terminal establishes a screen-casting link with the intelligent terminal through a screen-casting protocol.
In a specific implementation process, the device identifier of the designated convergence terminal carried in the second request message related to step 205 may not be matched with the device identifier of the designated convergence terminal, and at this time, the processes similar to steps 203 to 205 are repeatedly executed, except that the first convergence terminal, which is actively disconnected from the WIFI network of the intelligent terminal in similar step 203, becomes the second convergence terminal, the third convergence terminal, which is re-established with the intelligent terminal in corresponding similar step 204 for the WIFI network connection, is changed into the execution subject for confirming whether the designated convergence terminal is matched in corresponding similar step 205, and so on. It should be emphasized that the description definitions of "first", "second", "third", and the like referred to in the embodiments of the present invention do not represent that there is a special order relationship between them, but only the difference definition given by the same type of subject objects according to the sequence of their appearance in the text description is provided so as to clearly define each subject object.
Example 2:
in embodiment 1, the main flow process of the implementation of the present invention is described, however, the situations involved in the actual implementation process are more complicated and varied, for example: factors such as dissatisfaction of the user with the current room environment and the effect of the screen (such as screen size, screen resolution and the like) available for screen projection can occur, and the room is replaced. Thus, the process described in example 1 cannot be effectively extended into this scenario. Therefore, embodiment 2 of the present invention is a further improved scheme designed based on the above-mentioned requirements of the scenario based on embodiment 1, and in order to express the technical relevance and continuity between features, a part of the relevance method process in embodiment 1 is incorporated in the process of describing the embodiment of the present invention. In the implementation process of the embodiment of the present invention, there is a prerequisite technical condition that a corresponding relationship between an intelligent terminal device identifier and a device identifier of a designated fusion terminal is shared and stored among fusion terminals under unified management (for example, a hotel is used as a system architecture, and fusion terminals under the name of the hotel belong to the same system architecture), the sharing mechanism may be that each time a new fusion terminal receives a device identifier of the designated fusion terminal carried in a new request message, the device identifier is compared with a corresponding relationship between a device identifier of the designated fusion terminal originally obtained from a first fusion terminal and a device identifier of the intelligent terminal, if the corresponding relationship changes, it indicates that a user may change a place (for example, a bungalow for convenience), a distinguishing object in the following description method process is to directly introduce a part of a label, for example, "fusion terminal a", "convergence terminal B", however, the reference numerals are only for convenience of description of objects to be distinguished, and have no other special limiting meaning, as shown in fig. 3, the method includes:
in step 301, the mobile phone scans the convergence terminal a.
The intelligent terminal described in embodiment 1 is embodied as a mobile phone in the embodiment of the present invention. Correspondingly, the convergence terminal A scanned by the mobile phone is the currently specified convergence terminal.
In step 302, the current WIFI of the mobile phone is connected to the convergence terminal B, and a first request message is sent to the convergence terminal B.
Wherein, the first request message carries the device identifier of the convergence terminal A.
In step 303, if the convergence terminal B determines from the first request message that the device identifier matches the device identifier of itself, the screen-casting link is successfully established, and the process ends; if not, go to step 304.
In step 304, if the correspondence relationship between the mobile phone and the designated convergence terminal stored previously by the convergence terminal B is consistent with the relationship between the mobile phone and the device identifier of the convergence terminal a carried in the first request, the convergence terminal disconnects the WIFI link with the mobile phone, and sets that the mobile phone cannot reconnect the convergence terminal B in a limited time, and then the step 302 is performed, and the mobile phone further connects to other convergence terminals through WIFI to execute similar actions. If the correspondence relationship between the mobile phone and the designated convergence terminal, which is previously stored by the convergence terminal B, is inconsistent with the relationship between the mobile phone carried in the first request and the device identifier of the convergence terminal a, go to step 305.
In step 305, the convergence terminal B notifies other convergence terminals to reset the time-limited setting of the corresponding mobile phone. Deleting the old record before, adding the relationship between the mobile phone and the appointed fusion terminal (the deletion and the addition are that other fusion terminals are informed to update the relationship between the mobile phone and the appointed fusion terminal), disconnecting the WIFI link with the mobile phone by the fusion terminal, and forbidding the mobile phone from being reconnected for a certain time. And turning to step 302, further connecting WIFI to other fusion terminals, and executing similar actions.
In addition, in step 305, the convergence terminal B notifies other convergence terminals to reset the time-limited setting of the corresponding mobile phone, deletes the old record before, and adds the relationship between the mobile phone and the designated convergence terminal. Or the convergence terminal B informs the central server, and other convergence terminals know the central server.
Another situation that is implemented as an embodiment of the present invention relates to a situation that another convergence terminal deletes a local time-limited record for the intelligent terminal, and may also be that the first convergence terminal loses a WIFI network link with the intelligent terminal, and then the method further includes:
and the first convergence terminal sends a notification message aiming at the reset of the time limit setting of the intelligent terminal to other convergence terminals under unified management so that the other convergence terminals delete the local time limit record aiming at the intelligent terminal.
The above-mentioned complementary method logic considers the network disconnection between the mth convergence terminal and the mth convergence terminal due to the user behavior, rather than the case of the active network disconnection of the mth convergence terminal described in embodiment 1 of the present invention. The above situation can be understood as that the connection relationship of the mth convergence terminal originally established with the WIFI network link is disconnected due to the switching of the rooms by the user. At this time, as a consideration of the robustness of the scheme, it is necessary to inform other fusion terminals to delete the local time-limited records for the intelligent terminal; otherwise, the same problem as set forth in embodiment 3 of the present invention may occur, that is, the designated fusion terminal to be screen-projected in the contracting room after the user changes may incorporate the intelligent terminal into the time limit record in the process similar to the method in embodiment 1, so that the screen-projecting link that can be established cannot be completed within the time limit.
As an alternative implementation scheme, the convergence terminal M notifies the central server, and the central server analyzes whether the corresponding relationship is changed, and finally sends the above notification message of resetting the time limit setting for the intelligent terminal to other convergence terminals when it is determined that the corresponding relationship of the same intelligent terminal is changed. At this time, for the correspondence between the latest intelligent terminal device identifier fed back to the other convergence terminals and the device identifier of the designated convergence terminal, the central server may not perform corresponding operations under the condition that the central server is owned, but the management of each convergence terminal on the correspondence is centralized to itself to complete.
After the central server is introduced, in the embodiment of the present invention, the trigger environment for the notification message recorded when the convergence terminal device deletes the time limit may be further extended to a more specific scenario. For example: some hotel fusion terminals are not powered on normally, and are powered on only by inserting a house card. At this time, preferably, each central server further maintains an online status with each convergence terminal, and at this time, once a corresponding convergence terminal is disconnected in a correspondence relationship between a certain terminal device and a certain convergence terminal that is stored in history, the above-mentioned notification message for resetting the time-limited setting of the intelligent terminal is sent to other convergence terminals. Correspondingly, the calculation of the time-limited time length at this time may be dynamically generated by the central server according to the number of the fusion terminals which are on-line in the range of detectable signal strength of the intelligent terminal in the current jurisdiction range of the central server, and the fusion terminals are issued by the central server.
Example 3:
in the embodiment of the present invention, the related method in embodiment 1 is instantiated and explained in combination with a specific application scenario, assuming that a room 1 where a user is located, a convergence terminal 1 is a screen projection target device, and a convergence terminal 2 is a next room (expandable to a convergence terminal 3, a convergence terminal 4,. and a convergence terminal n), in the embodiment of the present invention, an intelligent terminal is directly described as a mobile phone; the convergence terminal 1 is divided into a set top box service part and an optical modem service part for explanation, and two converged service main bodies are embodied; the operation of supporting the screen projection of the mobile phone of the user depends on the operation of the optical modem side, and the operation of introducing the service part of the set-top box into the hotel launcher (first page) is most common in consideration of the typical use mode of the convergence terminal 1 in the actual use process. To simplify the process, as shown in fig. 4 and 5, the steps of the embodiment of the present invention describe how to switch the WIFI connection from the initially connected convergence terminal 2 to the target device convergence terminal 1:
in step 401, the mobile phone connects to the WIFI network of the convergence terminal 2, logs in to a hotel applet or a client (the implementation is not limited thereto, and the subsequent two-dimensional code scanning operation can also be performed directly through the wechat or payment platform in the specific implementation process), and scans the two-dimensional code on the convergence terminal 1 by using the camera in the applet or client interface.
The service part of the set-top box in the convergence terminal 1 enters a hotel launcher (home page), and a user can obtain the two-dimensional code information (including the MAC address of the optical modem service side in the convergence terminal 1) of the convergence terminal 1 through the interface operation of the service part of the set-top box.
In step 402, the mobile phone initiates an HTTP request to the specified URL, where the request carries the MAC address of the optical modem service side of the convergence terminal 1.
The appointed URL can be arbitrarily predefined and can be identified by each convergence terminal to know the content carried in the corresponding HTTP request, the intention of the corresponding HTTP request and the content carried by the HTTP response; the above-mentioned setting will be specifically described in each relevant step of the embodiment of the present invention, and will not be described herein again.
In step 403, the convergence terminal 2 and the mobile phone are in a local area network, receive the HTTP request and analyze that the MAC address information is verified with the MAC address of the optical modem service side in the current convergence terminal 2, and if the verification fails, step 404 is performed.
In step 404, the convergence terminal 2 in the lan sends an HTTP response to notify the mobile phone that the verification fails, and the mobile phone may prompt the user that the verification fails according to the error information of the HTTP response.
In step 405, the convergence terminal 2 in the local area network actively disconnects the WIFI connection with the mobile phone, and limits that the mobile phone cannot be connected to the WIFI network of the convergence terminal 2 within the time limit setting T according to the device identifier of the mobile phone itself.
In step 406, when the mobile phone detects that the WIFI network link is disconnected, the convergence terminal of the available WIFI network is reconnected (for example, the convergence terminal 1 described above is used in the following steps as a main body for establishing the WIFI link with the mobile phone directly), carries the MAC address information stored in step 401, and initiates new HTTP request authentication information to the specified URL of the local area network.
In step 407, the convergence terminal 1 terminal in the local area network receives the new HTTP request, resolves the MAC address to check with the MAC address of the optical modem service side of the current convergence terminal 1, and if the check is successful, proceeds to step 408, and if the check is unsuccessful, proceeds to step 405, where it needs to be supplemented that skipping to step 405 is to express an iterative process, and therefore, after each skipping, the execution main body of the corresponding step 405 may be replaced with the convergence terminal X currently having the WIFI link established with the mobile phone, where X is a natural number.
In step 408, the mobile phone receives the verification success message of the convergence terminal 1 in the local area network, and starts to search for the screen projection device in the WIFI local area network established by the convergence terminal 1 in the office.
In step 409, the mobile phone searches for the screen projection device, establishes a screen projection connection, and initiates a screen projection service.
The corresponding screen projection device and the convergence terminal 1 represented by the above steps 408 and 409 belong to two independent device individuals, and the association characteristics established with the mobile phone are as follows: the screen projection equipment and the mobile phone are both established with a WIFI network link with the convergence terminal 1, namely in the same local area network, so that the subsequent screen projection service can be completed by utilizing the existing related screen projection protocol.
Still taking the scenario given by the embodiment of the present invention as an example, the difference is that, next, a scenario where multiple converged terminals exist is shown through the timing diagram of fig. 6, and the screen-casting authentication iteration process in the step process of the above embodiment corresponds to the general name of the checking process of receiving the HTTP request and analyzing the MAC address information and the MAC address of the optical modem service side in the current converged terminal 2 in step 403 of the embodiment of the present invention, which is referred to in fig. 6.
As can be easily found from fig. 6, in a typical convergence terminal scenario (that is, more than the screen-projection authentication completed between the convergence terminal 1 and the convergence terminal 2 shown in the above steps 401 to 409 in this embodiment, the related convergence terminal is shown in the convergence terminal n), the corresponding convergence terminal disconnects from the WIFI network of the mobile phone, and the WIFI network of the mobile phone reconnecting to different convergence terminals is associated with the number of convergence terminals that the encountered destination convergence terminal passes through, taking fig. 6 as an example, the final destination convergence terminal is the convergence terminal n, where n is a natural number greater than or equal to 3.
Example 4:
fig. 7 is a schematic diagram of a configuration of a screen projection apparatus for implementing a convergence terminal according to an embodiment of the present invention.
