To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The terms referred to in this application will first be introduced and explained:
edge nodes: the network node has fewer intermediate links from the user terminal which is finally accessed in the network, and has better response capability and connection speed for the user terminal which is finally accessed. Specifically, an edge node is a logical abstraction of basic commonality capabilities of a plurality of product forms on the edge side, such as an edge gateway, an edge controller, and an edge server, and these product forms have commonality capabilities such as edge side real-time data analysis, local data storage, and real-time network connection.
And (3) edge calculation: refers to processing and analyzing data at an edge node of the network.
Multi-line machine room: the multi-line machine room is actually a machine room with multiple lines accessed in the machine room, and the multi-line machine room is divided into two modes, one mode is a multi-line single IP (Internet Protocol) mode, namely a BGP (Border Gateway Protocol) mode, and the other mode is a multi-line multi-IP access mode, namely, an independent IP is respectively used in each operator's network. By setting the router of the internal route of the multi-line machine room and analyzing the BGP automatic route, the user terminal of each operator can quickly access the server in the machine room through the route of the operator to which the user terminal belongs.
The special communication line is connected: the method is characterized in that the network is communicated by optical cables, or wireless communication modes such as satellites and microwaves, or leased telephone lines and N special lines, and the quality of a communication link between two connected ends can be guaranteed.
In the current cloud game scheme, a cloud game started by a user terminal runs on a game server which establishes a connection link with the cloud game, and the game server only sends a game picture of the cloud game running on the game server to the user terminal which starts the cloud game.
Fig. 1 is a schematic flowchart of a method for synchronously displaying multiple terminals of a cloud game according to an embodiment of the present application, where an execution subject of the method may be a central server bs (business server), and as shown in fig. 1, the method may include:
step S101, receiving a synchronous display request sent by a second terminal, wherein the synchronous display request comprises synchronous display authorization information.
The first terminal in the following may be understood as a master terminal in a multiplayer game or live game, that is, a cloud game is first started by the first terminal. The second terminal may be understood as a slave terminal, that is, it requests access to the cloud game (i.e., receives and displays game screen information of the cloud game) after the first terminal starts the cloud game. It is understood that the number of the first terminals is one, and the number of the second terminals may be one or more, that is, the cloud game displayed by the first terminal may be synchronously displayed by a plurality of second terminals.
The synchronous display authorization information is used for indicating an object of the second terminal, which is requested to be synchronously displayed, namely the cloud game of which terminal the second terminal requests to be synchronously displayed. In practical applications, the specific form of the synchronization authorization information may be a secret key, such as a series of "123456" digital passwords.
Step S102, comparing the synchronous display authorization information with preset synchronous display authorization information, wherein the preset synchronous display authorization information is used for indicating a communication link between a first terminal displaying the cloud game and a target game server GS running the cloud game.
The preset synchronous display authorization information is used for indicating a communication link between a first terminal displaying the cloud game and a target game server GS running the cloud game, namely the first terminal corresponding to the preset synchronous display authorization information, the cloud game displayed on the first terminal, the target GS and the cloud game running on the target GS can be determined through the preset synchronous display information. In practical applications, the specific form of the preset synchronization authorization message may be a secret key form, such as a string of "123456" digital codes.
The game picture information may include one or more of video information, audio information, and operation information encoded by the target GS. After receiving the game picture information sent by the target GS, the terminal decodes the encoded video information and audio information, thereby displaying the game picture on the terminal and playing the game audio; and decoding the coded operation information so as to display a corresponding game operation instruction control at the terminal, sending the operation instruction to a target GS after the terminal receives the operation instruction of the user aiming at the operation control, and simulating the operation instruction by the target GS to generate corresponding video information and audio information.
Specifically, the synchronous display authorization information is compared with the preset synchronous display authorization information to determine whether the synchronous display authorization information is matched with the preset synchronous display authorization information, because the synchronous display authorization information is used for indicating which terminal the second terminal requests to synchronously display the cloud game, and the preset synchronous display authorization information is used for indicating a communication link between the first terminal displaying the cloud game and a target game server GS running the cloud game, if the synchronous display authorization information is matched with the preset synchronous display authorization information, the second terminal requests to synchronously display the cloud game displayed by the first terminal. In practical applications, when both are in the form of a key, the match is such that both are the same, e.g., both are the cipher string "123456".
And step S103, if the synchronous display authorization information is matched with the preset synchronous display authorization information, sending the identification information of the target GS to the second terminal so that the second terminal establishes a communication link with the target GS, receiving game picture information of running of the cloud game sent by the target GS, and synchronously displaying the cloud game with the first terminal.
Specifically, if the synchronous display authorization information matches the preset synchronous display authorization information, it indicates that the second terminal requests to synchronously display the game picture displayed by the first terminal, the second terminal establishes a communication link with the target GS, the target GS sends the game picture information to the first terminal and the second terminal, and the first terminal and the second terminal decode the received game picture information respectively to realize synchronous display. It can be understood that, when the number of the second terminals is multiple, after determining that the synchronous display authorization information corresponding to each second terminal matches the preset synchronous display authorization information by the above method, the target GS sends the game picture information to the first terminal and the multiple second terminals respectively, so as to implement that the multiple second terminals synchronously display the cloud game displayed by the first terminal. In addition, in order to achieve synchronization of multi-terminal display, it is necessary to ensure the quality of the communication link between the target GS and the first and second terminals, and the quality of the communication link may be ensured by matching the region information of the target GS and the terminal and the information of the operator, or may be ensured by a manner of forwarding a server in the following text, which is not limited herein.
It should be noted that the synchronous display authorization information of the second terminal may also be used to indicate content information of the game screen information requested by the second terminal, and correspondingly, the preset synchronous display authorization information may also be used to indicate content information of the game screen information to be provided by the target GS. Since the game screen information may include one or more of video information, audio information, and operation information, the synchronous display authorization information may also be used to indicate that the game screen information requested by the second terminal is one or more of video information, audio information, and operation information. For example, in a live game scene, since the second terminal only needs to watch a game picture and does not need to perform game operation, the synchronous display authorization information may indicate that the requested game picture information is video information and audio information, after the second terminal establishes a communication link with the target GS, the target GS encodes the video information and audio information of the cloud game operation and transmits the encoded video information and audio information to the second terminal, and the second terminal displays a picture of the cloud game and plays a corresponding audio. In a multi-player game scenario, since the second terminal needs to watch a game picture and also needs to perform game operation, and the synchronous display authorization information can indicate that the requested game picture information is video information, audio information and operation information, after the second terminal establishes a communication link with the target GS, the target GS encodes the video information, the audio information and the operation information of the running cloud game and sends the encoded video information, audio information and operation information to the second terminal, and the second terminal displays the picture of the cloud game and plays corresponding audio, and can also feed back the received user instruction to the target GS.
According to the scheme provided by the application, after the first terminal establishes a communication link with a target GS running a cloud game, the BS receives a synchronous display request sent by at least one second terminal, and if synchronous display authorization information in the synchronous display request is matched with preset synchronous display authorization information, the target GS is dispatched to the second terminal, so that the second terminal can receive game picture information corresponding to the cloud game displayed by the first terminal and sent by the target GS, multi-terminal synchronous display of the cloud game is realized, and a foundation is provided for scenes such as various live games, multi-player games and the like.
In an optional embodiment of the present application, the method may further comprise:
and after the first terminal establishes the communication link with the target GS, receiving preset synchronous display authorization information sent by the first terminal.
After the first terminal establishes a communication link with the target GS, the first terminal determines corresponding preset synchronous display authorization information according to a specific application scene, and sends the preset synchronous display authorization information to the BS, and the BS stores the preset synchronous display authorization information and serves as a comparison basis in a subsequent comparison process. Meanwhile, the first terminal determines synchronous display authorization information matched with the preset synchronous display authorization information according to the preset synchronous display authorization information, and releases the synchronous display authorization information through related channels, so that users with synchronous display requirements can obtain the synchronous display authorization information.
In an optional embodiment of the present application, the synchronous display request further includes region information of the second terminal, and the method may further include:
when a communication link between a second terminal and a target GS meets a preset condition, determining a target forwarding server TS (Turn Server) based on regional information of the second terminal, wherein the target TS is arranged in a multi-line machine room;
and sending the identification information of the target TS to the second terminal so that the second terminal establishes a communication link with the target GS through the target TS.
The region information in the synchronization display request may be DNS (Domain Name System) information, and specifically may be an IP address. In practical applications, specific region information can be obtained by analyzing the DNS information.
When the communication link between the second terminal and the target GS meets the preset condition, the quality of the communication link established by the direct connection between the second terminal and the target GS is poor, and the final presentation effect of the cloud game cannot be ensured. This may occur because the second terminal does not match the geographical information of the target GS, or because the second terminal is not the same operator as the target GS, or because of other line faults. The second terminals of the users of the operators can access the TS in the multi-line machine room through the lines of the operators to which the second terminals of the users of the operators belong. Similarly, the multi-line machine room is connected with lines of different operators, so that the TS and the target GS are connected through the line of the same operator, delay and instability caused by the fact that the line crosses an operator network are avoided, the quality of a communication link between the TS and the target GS can be guaranteed to be good, and in practical application, the TS arranged in the multi-line machine room can be connected with the target GS through a special communication line of the operator to which the target GS belongs, so that the quality of the communication link between the TS and the target GS is guaranteed to be good. The target TS is determined from the TSs in the network and is used as an intermediate server between the second terminal and the target GS, and communication between the second terminal and the target GS is forwarded through the target TS.
If the target TS is used as an intermediate server to connect the second terminal and the target GS, and the quality of the communication link between the target TS and the target GS is good, the quality of the communication link between the target TS and the second terminal directly determines the quality of the communication link between the second terminal and the target GS. And because the target TS and the operator information of the second terminal can be matched all the time, whether the target TS is matched with the region information of the second terminal can directly influence the quality of the communication link between the target TS and the second terminal, that is, whether the target TS is matched with the region information of the second terminal directly influences the quality of the communication link between the second terminal and the target GS, so that the target TS can be determined based on the region information of the second terminal.
When a plurality of candidate target TSs are determined based on the region information of the second terminal, the target TS used as the intermediate server may be further screened according to the load condition of each candidate target TS, for example, a TS with the largest available load among the candidate target TSs is determined as the target TS.
Specifically, when the quality of the communication link between the second terminal and the target GS does not meet a preset condition (the link quality is good), and the final presentation effect of the cloud game can be ensured, the second terminal and the target GS directly establish the communication link. When the quality of a communication link between the second terminal and the target GS meets a preset condition (the link quality is poor) and the final presentation effect of the cloud game cannot be guaranteed, the second terminal and the target GS establish a communication link through a target TS, namely the TS is used as an intermediate server and respectively establishes communication links with the second terminal and the target GS.
In an optional embodiment of the present application, the communication link between the second terminal and the target GS satisfies a preset condition, including:
the communication time delay of a communication link between the second terminal and the target GS is larger than a first set value; and/or the presence of a gas in the gas,
and the communication packet loss rate of the communication link between the second terminal and the target GS is greater than a second set value.
Wherein, to ensure that the cloud game has a good presentation effect, at least the following three aspects need to be ensured:
(1) the timeliness is about 100ms, when the time for transmitting the game picture at the cloud to the user terminal exceeds 100ms, the user can distinguish, namely, the user has the feelings of 'slow half-beat', 'no-hand-following' and the like of the game picture, and the timeliness is guaranteed, namely, the time for transmitting the game picture at the cloud to the terminal does not exceed the set time (for example, 100 ms). For example, after a terminal triggers a certain skill in a cloud game, a user can see an action picture of the skill released by a character after 1-2s, and the user can feel that the game picture is not in hand, which means that the timeliness of the game is not guaranteed.
(2) Fluency, mainly measured by frame rate (unit fps), when the frame rate is too low (for example, frame rate <20fps), the game picture will appear obvious fluency; when the frame interval is not uniform, the game picture is not smooth, the smoothness is ensured, namely the frame rate is ensured to be larger than the set frame rate (for example, 20fps), the inter-frame interval is ensured to be uniform, otherwise, the game picture finally presented by the local terminal is fast and slow, and the user has the feeling of unsmooth game picture.
(3) The image quality, is that for a picture with the same resolution, the image quality of a picture with less noise is better than that of a picture with more noise, and the image quality is guaranteed, that is, the number of noise in the picture is guaranteed to be smaller than a set value.
Specifically, to ensure timeliness, fluency and image quality in the running process of the cloud game, the quality of the communication link between the second terminal and the target GS needs to be ensured, and specifically, timeliness, fluency and image quality in the running process of the cloud game can be ensured by ensuring the delay and/or packet loss rate of the communication link between the second terminal and the target GS. When the time delay of the communication link between the cloud game and the cloud game is larger than a first set value and/or the packet loss rate is larger than a second set value, the quality of the communication link between the cloud game and the cloud game is considered to be poor, and the final presentation effect of the cloud game cannot be guaranteed. It is to be understood that both the first setting value and the second setting value can be set according to actual situations, and are not limited herein.
In an optional embodiment of the present application, the communication link between the second terminal and the target GS satisfies a preset condition, including:
the region information of the second terminal is not matched with the region information of the target GS; and/or the presence of a gas in the gas,
the operator information of the second terminal does not match the operator information of the target GS.
When the second terminal is matched with the region information of the target GS and the operator information of the target GS, because the second terminal and the target GS do not need to cross regions or operators when communicating, the quality of a communication link established between the second terminal and the target GS is good, and the requirement of cloud game operation can be met. And when the region information of the second terminal and the target GS are not matched, that is, the regions of the second terminal and the target GS are different, the operator information of the second terminal and the operator information of the target GS are not matched, that is, the operators corresponding to the second terminal and the operators are different, or the region information of the second terminal and the operator information of the target GS are not matched, because the second terminal and the target GS need to cross regions and/or operators during communication, the quality of the communication link established between the second terminal and the target GS is poor, and the quality of the communication link established between the second terminal and the target GS is poor, so that the requirement of cloud game operation cannot be met.
In an optional embodiment of the present application, determining the target TS based on the region information of the second terminal includes:
acquiring regional information of each TS corresponding to a central server BS;
and determining the TS of which the region information is matched with the region information of the second terminal in each TS as a target TS.
Specifically, the BS in the network has a plurality of corresponding TSs, each TS is set in a multi-line machine room, and the multi-line machine room enables second terminals of users of different operators to access the TSs through lines of the respective operators, as can be seen from the foregoing description, it is only necessary to consider whether the TSs are matched with the region information of the second terminals or not and load information of the TSs to obtain a target TS, and the BS generally takes the TS with the highest matching degree with the region information of the second terminals and the largest available load as the target TS.
In an optional embodiment of the present application, the method may further comprise:
receiving a scheduling request aiming at the GS sent by a first terminal, and determining a target GS in response to the scheduling request;
and sending the identification information of the target GS to the first terminal so that the first terminal establishes a communication link with the target GS, and receiving game picture information of the cloud game running sent by the target GS.
After receiving the scheduling request sent by the first terminal, the BS may determine the target GS according to a preset rule, or may determine the target GS according to the own attribute (e.g., regional information, operator information, etc.) of the first terminal, where a manner in which the BS determines the target GS is not limited herein.
In an optional embodiment of the present application, the scheduling request includes region information and operator information of the first terminal;
determining a target GS for running the cloud game in response to the scheduling request, including:
and determining a target GS based on the region information and the operator information of the first terminal.
Further, determining a target GS based on the region information and the operator information of the first terminal includes:
acquiring region information and operator information of each GS corresponding to the BS;
and determining the target GS based on the region information and the operator information of the first terminal and the region information and the operator information of each GS.
Specifically, since whether the geographical information of the first terminal and the GS are matched and whether the operator information of the first terminal and the GS are matched determine whether the quality of the communication link established between the first terminal and the GS is good or bad, when the BS schedules the GS for the first terminal, the BS takes the GS matched with the geographical information of the first terminal and the GS matched with the operator information of the first terminal as the target GS, and it can be understood that the load condition of each GS is also considered when determining the target GS, so as to ensure that the determined target GS has an available load. When there is no GS that satisfies the above condition, the target GS may be determined according to an actual situation, and in this case, the quality of the communication link established between the determined target GS and the first terminal may be poor, and the final presentation effect of the cloud game cannot be ensured.
Fig. 2 is a schematic flowchart of a method for synchronously displaying multiple terminals of a cloud game according to an embodiment of the present application, where an execution subject of the method may be a second terminal, and as shown in fig. 2, the method may include:
step S201, sending a synchronous display request to the central server BS, where the synchronous display request includes synchronous display authorization information, so that the BS compares the synchronous display authorization information with preset synchronous display authorization information, where the preset synchronous display authorization information is used to indicate a communication link between a first terminal displaying the cloud game and a target game server GS running the cloud game.
The first terminal can be understood as a master terminal in a multiplayer game or live game, namely, the cloud game is started by the first terminal firstly. The second terminal may be understood as a slave terminal, that is, it requests access to the cloud game (i.e., receives and displays game screen information of the cloud game) after the first terminal starts the cloud game. It is understood that the number of the second first terminals is one, and the number of the second terminals may be one or more, that is, the cloud game displayed by the first terminal may be synchronously displayed by a plurality of second terminals.
The synchronous display authorization information is used for indicating an object of the second terminal, which is requested to be synchronously displayed, namely the cloud game of which terminal the second terminal requests to be synchronously displayed. In practical applications, the specific form of the synchronization authorization information may be a secret key, such as a series of "123456" digital passwords.
The preset synchronous display authorization information is used for indicating a communication link between a first terminal displaying the cloud game and a target game server GS running the cloud game, namely the first terminal corresponding to the preset synchronous display authorization information, the cloud game displayed on the first terminal, the target GS and the cloud game running on the target GS can be determined through the preset synchronous display information. In practical applications, the specific form of the preset synchronization authorization message may be a secret key form, such as a string of "123456" digital codes.
The game picture information may include one or more of video information, audio information, and operation information encoded by the target GS. After receiving the game picture information sent by the target GS, the terminal decodes the encoded video information and audio information, thereby displaying the game picture on the terminal and playing the game audio; and decoding the coded operation information so as to display a corresponding game operation instruction control at the terminal, sending the operation instruction to a target GS after the terminal receives the operation instruction of the user aiming at the operation control, and simulating the operation instruction by the target GS to generate corresponding video information and audio information.
Specifically, the synchronous display authorization information is compared with the preset synchronous display authorization information to determine whether the synchronous display authorization information is matched with the preset synchronous display authorization information, because the synchronous display authorization information is used for indicating which terminal the second terminal requests to synchronously display the cloud game, and the preset synchronous display authorization information is used for indicating a communication link between the first terminal displaying the cloud game and a target game server GS running the cloud game, if the synchronous display authorization information is matched with the preset synchronous display authorization information, the second terminal requests to synchronously display the cloud game displayed by the first terminal. In practical applications, when both are in the form of a key, the match is such that both are the same, e.g., both are the cipher string "123456".
Step S202, if the synchronous display authorization information is matched with the preset synchronous display authorization information, the identification information of the base target GS sent by the BS is received.
Step S203, establishing a communication link with the target GS based on the identification information of the target GS, receiving game picture information of running of the cloud game sent by the target GS, and synchronously displaying the cloud game with the first terminal.
Specifically, if the synchronous display authorization information matches the preset synchronous display authorization information, it indicates that the second terminal requests to synchronously display the game picture displayed by the first terminal, the second terminal establishes a communication link with the target GS, the target GS sends the game picture information to the first terminal and the second terminal, and the first terminal and the second terminal decode the received game picture information respectively to realize synchronous display. It can be understood that, when the number of the second terminals is multiple, after determining that the synchronous display authorization information corresponding to each second terminal matches the preset synchronous display authorization information by the above method, the target GS sends the game picture information to the first terminal and the multiple second terminals respectively, so as to implement that the multiple second terminals synchronously display the cloud game displayed by the first terminal. In addition, in order to achieve synchronization of multi-terminal display, it is necessary to ensure the quality of the communication link between the target GS and the first and second terminals, and the quality of the communication link may be ensured by matching the region information of the target GS and the terminal and the information of the operator, or may be ensured by a manner of forwarding a server in the following text, which is not limited herein.
It should be noted that the synchronous display authorization information of the second terminal may also be used to indicate content information of the game screen information requested by the second terminal, and correspondingly, the preset synchronous display authorization information may also be used to indicate content information of the game screen information to be provided by the target GS. Since the game screen information may include one or more of video information, audio information, and operation information, the synchronous display authorization information may also be used to indicate that the game screen information requested by the second terminal is one or more of video information, audio information, and operation information. For example, in a live game scene, since the second terminal only needs to watch a game picture and does not need to perform game operation, the synchronous display authorization information may indicate that the requested game picture information is video information and audio information, after the second terminal establishes a communication link with the target GS, the target GS encodes the video information and audio information of the cloud game operation and transmits the encoded video information and audio information to the second terminal, and the second terminal displays a picture of the cloud game and plays a corresponding audio. In a multi-player game scenario, since the second terminal needs to watch a game picture and also needs to perform game operation, and the synchronous display authorization information can indicate that the requested game picture information is video information, audio information and operation information, after the second terminal establishes a communication link with the target GS, the target GS encodes the video information, the audio information and the operation information of the running cloud game and sends the encoded video information, audio information and operation information to the second terminal, and the second terminal displays the picture of the cloud game and plays corresponding audio, and can also feed back the received user instruction to the target GS.
According to the scheme provided by the application, after the first terminal establishes a communication link with a target GS running a cloud game, the BS receives a synchronous display request sent by at least one second terminal, and if synchronous display authorization information in the synchronous display request is matched with preset synchronous display authorization information, the target GS is dispatched to the second terminal, so that the second terminal can receive game picture information corresponding to the cloud game displayed by the first terminal and sent by the target GS, multi-terminal synchronous display of the cloud game is realized, and a foundation is provided for scenes such as various live games, multi-player games and the like.
In an optional embodiment of the present application, the synchronous display request further includes region information of the second terminal, and the establishing of the communication link with the target GS based on the identification information of the target GS includes:
when a communication link between a second terminal and a target GS meets a preset condition, receiving identification information of a target forwarding server TS, which is sent by a BS and determined based on region information of the second terminal;
and passing through a communication link between the target TS and the target GS based on the identification information of the target TS.
The region information in the synchronization display request may be DNS (Domain Name System) information, and specifically may be an IP address. In practical applications, specific region information can be obtained by analyzing the DNS information.
When the communication link between the second terminal and the target GS meets the preset condition, the quality of the communication link established by the direct connection between the second terminal and the target GS is poor, and the final presentation effect of the cloud game cannot be ensured. This may occur because the second terminal does not match the geographical information of the target GS, or because the second terminal is not the same operator as the target GS, or because of other line faults.
The second terminals of the users of the operators can access the TS in the multi-line machine room through the lines of the operators to which the second terminals of the users of the operators belong. Similarly, the multi-line machine room is connected with lines of different operators, so that the TS and the target GS are connected through the line of the same operator, delay and instability caused by the fact that the line crosses an operator network are avoided, the quality of a communication link between the TS and the target GS can be guaranteed to be good, and in practical application, the TS arranged in the multi-line machine room can be connected with the target GS through a special communication line of the operator to which the target GS belongs, so that the quality of the communication link between the TS and the target GS is guaranteed to be good. The target TS is determined from the TSs in the network and is used as an intermediate server between the second terminal and the target GS, and communication between the second terminal and the target GS is forwarded through the target TS.
When the target TS is used as an intermediate server to connect the second terminal and the target GS, the quality of the communication link between the target TS and the target GS is better, and the quality of the communication link between the target TS and the second terminal directly determines the quality of the communication link between the second terminal and the target GS. And because the target TS and the operator information of the second terminal can be matched all the time, whether the target TS is matched with the region information of the second terminal can directly influence the quality of the communication link between the target TS and the second terminal, that is, whether the target TS is matched with the region information of the second terminal directly influences the quality of the communication link between the second terminal and the target GS, so that the target TS can be determined based on the region information of the second terminal.
When a plurality of candidate target TSs are determined based on the region information of the second terminal, the target TS used as the intermediate server may be further screened according to the load condition of each candidate target TS, for example, a TS with the largest available load among the candidate target TSs is determined as the target TS.
Specifically, when the quality of the communication link between the second terminal and the target GS does not meet a preset condition (the link quality is good), and the final presentation effect of the cloud game can be ensured, the second terminal and the target GS directly establish the communication link. When the quality of a communication link between the second terminal and the target GS meets a preset condition (the link quality is poor) and the final presentation effect of the cloud game cannot be guaranteed, the second terminal and the target GS establish a communication link through a target TS, namely the TS is used as an intermediate server and respectively establishes communication links with the second terminal and the target GS.
