Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a cloud gaming service system, a data processing method, and an electronic device. Background Art

[0002] Cloud gaming is a gaming technology based on cloud computing. In this mode, all games are run on the server, and the rendered game images are compressed and transmitted to the user via the network. Cloud computing is an internet-based computing method that enables shared hardware and software resources and information to be provided on-demand to computers and other devices.

[0003] In related technologies, cloud gaming can be played by directly linking a user-end device to a cloud gaming server device, which then transmits the cloud gaming data stream to the user-end device in real time via the connected link for playback. In actual applications, there may be a large number of users, with different users distributed in different regions. This results in a large physical distance between the cloud gaming server device and the user-end device, such as across different countries, provinces, and cities. Due to factors such as the network signals of different users and the link quality between the user-end device and the cloud gaming server device, the link for real-time transmission of the cloud gaming data stream may fluctuate, causing instability in the link for transmitting the cloud gaming data stream, affecting the transmission quality and latency of the cloud gaming data stream.

[0063] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0064] In order to improve the transmission quality of cloud gaming data and reduce transmission delay, an embodiment of the present invention provides a cloud gaming service system, a data processing method, and an electronic device. An embodiment of the present invention provides a cloud gaming service system, which includes a cloud gaming service end, a node allocation system, and a cloud gaming client. The cloud gaming service end includes a cloud gaming service node, an access node, and a streaming node. The cloud gaming client includes a first player client. The first player client is configured to send a cloud gaming access request to the node allocation system, wherein the cloud gaming access request carries identification information of the first player client. In response to a cloud gaming control instruction, the cloud gaming control instruction is sent to the first access node. The target cloud gaming data stream sent by the streaming node is received, and a game screen corresponding to the target cloud gaming data stream is played. The node allocation system is configured to receive the cloud gaming access request sent by the first player client, and based on the identification information of the first player client, the first access node is configured to receive the cloud gaming control instruction sent by the first player client, and forward the cloud gaming control instruction to the cloud gaming service node. The cloud gaming service node is configured to receive and respond to the cloud gaming control instruction, and send the target cloud gaming data stream to the streaming node. The streaming node is configured to receive the target cloud gaming data stream and send the target cloud gaming data stream to the first player client.

[0065] An embodiment of the present invention provides a cloud gaming service system, in which a node allocation system allocates a first access node to the first player client after receiving a cloud gaming access request sent by a first player client. The first access node forwards the cloud gaming control instruction sent by the first player client to the cloud gaming service node after receiving the cloud gaming control instruction sent by the first player client. The cloud gaming service node responds to the cloud gaming control instruction and sends the response result - the target cloud gaming data stream - to the streaming node. The streaming node then sends the target cloud gaming data stream to the first player client, and the first player client plays the game screen corresponding to the target cloud gaming data stream. In this process, the first player client interacts with the cloud gaming service node through the first access node allocated to it by the node allocation system, sends cloud gaming control instructions to the cloud gaming service node, and then the cloud gaming service node feeds back the target cloud gaming data stream to the first player client via the streaming node, so that the target cloud gaming data stream is transmitted through the cascade link between the nodes. Compared with the existing connection link for direct interaction between the player client and the cloud gaming service node, the transmission link of the cloud gaming data stream is more stable, thereby improving the transmission quality of the cloud gaming data transmission and reducing the transmission delay.

[0066] The following is a detailed description. Figure 1 A cloud gaming service system is provided in an embodiment of the present invention. The cloud gaming service system 100 includes: a cloud gaming server 110, a node allocation system 120 and a cloud gaming client 130. The cloud gaming server 110 may include: an access node 111, a cloud gaming service node 112, and a streaming node 113. The cloud gaming client 130 may include a first player client 131.

[0067] Among them, the cloud game server 110 can be a system or server for running cloud games, the cloud game client 130 can be a user terminal device, etc., and the cloud game client 130 can include multiple player clients. The node allocation system 120 can be a separate scheduling device or module, etc. In one example, the node allocation system 120 is an SFU (Selective Forwarding Unit) node allocation system. The cloud game service node 112, the access node 111 and the streaming node 113 can be separate devices or modules, or they can be service programs or processes in the cloud game server 110. In one example, the cloud game service node 112 can be a cloud phone or virtual machine virtualized by the cloud game manufacturer for running cloud games, and the streaming node 113 can be a streaming SFU node.

[0068] The first player client 131 is used to send a cloud game access request to the node allocation system 120 , where the cloud game access request carries identification information of the first player client 131 .

[0069] The node allocation system 120 is used to receive a cloud game access request sent by the first player client 131 and allocate a first access node to the first player client 131 based on the identification information of the first player client 131.

[0070] The first player client 131 is further configured to respond to the cloud game control instruction and send the cloud game control instruction to the first access node;

[0071] The first access node is configured to receive a cloud game control instruction sent by the first player client 131 and forward the cloud game control instruction to the cloud game service node 112;

[0072] The cloud game service node 112 is used to receive and respond to cloud game control instructions and send the target cloud game data stream to the push node 113;

[0073] The streaming node 113 is configured to receive the target cloud game data stream and send the target cloud game data stream to the first player client 131;

[0074] The first player client 131 is also used to receive the target cloud game data stream sent by the streaming node 113 and play the game screen corresponding to the target cloud game data stream.

[0075] When a cloud game player needs to access a cloud game, he sends a cloud game access request to the node allocation system 120 through the first player client 131. The cloud game access request carries the identification information of the first player client 131, so that the node allocation system 120 can allocate an access node to the cloud game player.

[0076] After receiving the cloud game access request sent by the first player client 131, the node allocation system 120 allocates a first access node ( Figure 1 access node 111).

[0077] In one possible implementation, the identification information of the first player client 131 may be the IP (Internet Protocol) address information of the first player client 131. Accordingly, the node allocation system 120 may be configured to receive a cloud gaming access request from the first player client 131 and, based on the IP address information of the first player client 131, allocate a first access node to the first player client 131.

[0078] When the identification information of the first player client 131 is the IP address information of the first player client 131 , the IP address information can represent the physical location of the first player client 131 , and the node allocation system 120 can allocate a reasonable access node to the first player client 131 based on the physical location of the first player client 131 .

[0079] In one possible implementation, the node allocation system 120 may be specifically used to: receive a cloud gaming access request sent by a first player client 131, and based on the IP address information of the first player client 131, allocate the first access node closest to the first player client 131, or allocate the first access node whose distance is less than a preset threshold to the first player client 131.

[0080] The node allocation system 120 may allocate the access node closest to the first player client 131 as the first access node to the first player client 131 based on the IP address information of the first player client 131, or may allocate the access node whose physical distance to the first player client 131 is less than a preset threshold as the first access node to the first player client 131. Preferably, the first access node may be an edge SFU access node, and the preset threshold may be set according to actual needs.

[0081] After node allocation system 120 assigns a first access node to first player client 131, first player client 131 can access the cloud game through the first access node. In response to a user's cloud game control command, first player client 131 sends the cloud game control command to the first access node, which then forwards the cloud game control command to cloud game service node 112. For example, the cloud game control command may be a command for a user to log in, register, or load a cloud game.

[0082] The cloud gaming service node 112 receives the cloud gaming control instruction forwarded by the first access node, responds to the cloud gaming control instruction, and sends the response result (the target cloud gaming data stream) to the streaming node 113. The streaming node 113 receives the target cloud gaming data stream, performs streaming processing on the target cloud gaming data stream, and forwards it to the first player client 131. The first player client 131 then plays the game screen corresponding to the target cloud gaming data stream.

[0083] In a possible implementation, the target cloud game data stream can be transmitted between the cloud game service node 112 and the streaming node 113 through the intranet to achieve rapid acquisition of the target cloud game data stream.

[0084] In one possible implementation, when the first access node assigned by the node allocation system 120 to the first player client 131 coincides with the streaming node 113, the streaming node 113 may directly forward the target cloud game data stream to the first player client 131 after receiving it. When the first access node assigned by the node allocation system 120 to the first player client 131 does not coincide with the streaming node 113, the streaming node 113 may forward the target cloud game data stream to the first access node after receiving it, and the first access node then forwards it to the first player client 131.

[0085] In one possible implementation, the target cloud game data stream may be an RTC (Real Time Communication) data stream. Using the RTC data stream may reduce the delay of the target cloud game data stream and reduce data jams.

[0086] An embodiment of the present invention provides a cloud gaming service system, in which a node allocation system allocates a first access node to the first player client after receiving a cloud gaming access request sent by a first player client. The first access node forwards the cloud gaming control instruction sent by the first player client to the cloud gaming service node after receiving the cloud gaming control instruction sent by the first player client. The cloud gaming service node responds to the cloud gaming control instruction and sends the response result - the target cloud gaming data stream - to the streaming node. The streaming node then sends the target cloud gaming data stream to the first player client, and the first player client plays the game screen corresponding to the target cloud gaming data stream. In this process, the first player client interacts with the cloud gaming service node through the first access node allocated to it by the node allocation system, sends cloud gaming control instructions to the cloud gaming service node, and then the cloud gaming service node feeds back the target cloud gaming data stream to the first player client via the streaming node, so that the target cloud gaming data stream is transmitted through the cascade link between the nodes. Compared with the existing connection link for direct interaction between the player client and the cloud gaming service node, the transmission link of the cloud gaming data stream is more stable, thereby improving the transmission quality of the cloud gaming data transmission and reducing the transmission delay.

[0087] In a possible implementation, in a scenario where multiple people participate in a cloud game, Figure 2 As shown, the above-mentioned cloud game client 130 may further include: a second player client 132 , and the cloud game server 110 may further include: a transfer node 114 .

[0088] In this embodiment of the present invention, to distinguish between cloud game players and invited players, the first player client 131 is used as the player client that initiates the invitation to join, and the player client that receives the invitation to join is used as the second player client 132. Any player client can be a cloud game player or an invited player.

[0089] The transfer node 114 is similar to the cloud gaming service node 112, access node 111, and streaming node 113, and can be a separate device or module, or a service program or process in the cloud gaming server 110. In one example, the transfer node 114 can be a transfer SFU node.

[0090] The first player client 131 is further configured to send a joining invitation message to at least one second player client 132 .

[0091] A cloud game player can invite other players to join the same cloud game for interaction. Specifically, the inviting cloud game player can send a join invitation message to one or more second player clients 132 via the first player client 131. The join invitation message can include a link containing information related to the target cloud game data stream requested by the first player client 131. For example, the join invitation message can include a link containing the cloud game room number where the first player client 131 is located or the identification information of the target cloud game data stream.

[0092] The second player client 132 is configured to receive the joining invitation information and send a joining request to the node allocation system 120 . The joining request carries identification information of the second player client 132 .

[0093] After receiving the joining invitation information sent by the first player client 131, the second player client 132 sends a joining request to the node allocation system 120. The joining request carries the identification information of the second player client 132 so that the node allocation system 120 can allocate an access node for it.

[0094] The node allocation system 120 is further configured to receive a joining request sent by the second player client 132, and allocate a second access node ( Figure 2 access node 111).

[0095] In one possible implementation, the identification information of the second player client 132 is the IP address information of the second player client 132; accordingly, the node allocation system 120 is specifically configured to receive a join request sent by the second player client 132, and based on the IP address information of the second player client 132, allocate the second access node that is closest to the second player client 132, or allocate the second access node that is closer than a preset threshold to the second player client 132.

[0096] The identification information of second player client 132 is the IP address information of second player client 132, which can represent the physical location of second player client 132. Based on the IP address information of second player client 132, node allocation system 120 can allocate the access node closest to second player client 132 as the second access node to second player client 132, or allocate the access node whose physical distance from second player client 132 is less than a preset threshold as the second access node to second player client 132. Preferably, the second access node can be an edge SFU access node, and the preset threshold can be set according to actual needs.

[0097] After the node allocation system 120 allocates the second access node to the second player client 132, the second player client 132 is further configured to send stream acquisition information to the second access node, where the stream acquisition information includes identification information of the target cloud game data stream.

[0098] After the node allocation system 120 allocates the nearest second access node to the second player client 132, the second player client 132 sends stream acquisition information to the second access node. The stream acquisition information may include identification information of the target cloud game data stream or information such as the cloud game room number, so that the second player client 132 can obtain the same target cloud game data stream as the first player client 131.

[0099] Furthermore, the second access node is configured to receive the stream acquisition information sent by the second player client 132, query the routing table to obtain the stream acquisition link corresponding to the stream acquisition information, and transmit the stream acquisition information to the target transfer node corresponding to the identification information of the target transfer node. The routing table includes stream acquisition links for multiple cloud gaming data streams, and the stream acquisition link corresponding to the stream acquisition information includes the identification information of the target transfer node.

[0100] The cloud gaming server 110 may also include a routing service node ( Figure 2 (not shown in the figure), the routing service node can be a separate module or process, etc. The routing service node maintains a routing table in real time. The routing table can contain stream links for multiple cloud game data streams, and the routing table can also be updated in real time according to the addition of players to the cloud game service system 100.

[0101] In one example, after the second access node receives the stream information sent by the second player client 132, it can first query whether the target cloud game data stream exists in the second access node based on the identification information of the target cloud game data stream contained in the stream information. If it exists, the second player client 132 can directly obtain and play the game screen corresponding to the target cloud game data stream from the second access node. If it does not exist, the routing table is queried to obtain the stream link corresponding to the stream information. The stream link corresponding to the stream information contains the identification information of the target transfer node, and then the target transfer node ( Figure 2 The transit node 114) pulls the target cloud game data stream.

[0102] The target transfer node is used to receive the stream information and send the stream information to the push node 113;

[0103] The streaming node 113 is also used to receive streaming information and send the target cloud game data stream corresponding to the streaming information to the target transfer node.

[0104] The target transfer node is also used to receive the target cloud game data stream sent by the push node 113 and send the target cloud game data stream to the second access node.

[0105] The second access node is also used to receive the target cloud game data stream sent by the target transfer node, and send the target cloud game data stream to the second player client 132.

[0106] The second player client 132 is also used to receive the target cloud game data stream sent by the second access node and play the game screen corresponding to the target cloud game data stream.

[0107] The target transfer node forwards the stream acquisition information of the second player client 132 and forwards the stream acquisition information to the push node 113. The push node 113 stores the target cloud game data stream pushed to the push node 113 by the cloud game service node 112. The target cloud game data stream is the data stream corresponding to the cloud game control instruction of the cloud game service node 112 in response to the first player client 131. The target transfer node then pulls the target cloud game data stream from the push node 113 and forwards the pulled target cloud game data stream to the second access node. The second access node forwards the target cloud game data stream to the second player client 132, and the second player client 132 plays the game screen corresponding to the target cloud game data stream.

[0108] In an embodiment of the present invention, a first player client can invite at least one second player client to interact with the same cloud game to realize multi-player cloud game interaction. During the multi-player cloud game interaction, the node allocation system allocates an access point nearby to each invited player client, and further pulls the target cloud game data stream through the access node allocated to the invited player client. During the process of pulling the target cloud game data stream, data cascade forwarding is supported between the nodes on the transmission link, so that the transmission link of the target cloud game data stream is more stable than the connection link between the player client directly and the cloud game service node, thereby improving the transmission quality of the cloud game data transmission and reducing the transmission delay.

[0109] In a possible implementation, the cloud gaming client 130 may further include a viewing client, and the streaming node 113 may further be used to convert the RTC data stream into an RTMP (Real Time Messaging Protocol) data stream, and send the RTMP data stream to a CDN (Content Delivery Network) node.

[0110] When the streaming node 113 obtains the RTC data stream (that is, the target cloud game data stream) pushed by the cloud game service node 112, it can perform real-time stream processing on the RTC data stream, convert the RTC data stream into an RTMP data stream, and send the RTMP data stream to the CDN node, so that in scenarios such as live broadcast, the cloud game client can obtain and broadcast the game screen corresponding to the target cloud game data stream from the CDN node.

[0111] The spectator client is used to obtain the RTMP data stream from the CDN node and play the game screen corresponding to the RTMP data stream.

[0112] The viewing client can be the client where the user watching the cloud game is located in the cloud game live broadcast scene. The viewing client pulls the RTMP data stream from the CDN node. The RTMP data stream is the target cloud game data stream corresponding to the cloud game controlled by the player client. The viewing client plays the game screen corresponding to the RTMP data stream to watch the cloud game in which the player client participates.

[0113] In an embodiment of the present invention, the streaming node can push the target cloud game data stream to the access node closest to the player client, so that the player client can obtain and play the game screen corresponding to the target cloud game data stream from the access node; it can also convert the target cloud game data stream into an RTMP data stream and send it to the CDN node, so that the spectator client in live broadcast and other scenarios can obtain and broadcast the game screen corresponding to the target cloud game data stream from the CDN node, realizing multiple cloud game operation modes.

[0114] In a possible implementation, the first player client 131 may also be configured to respond to a cloud game operation instruction and send the cloud game operation instruction to the first access node.

[0115] The first access node is also used to receive cloud game operation instructions and send the cloud game operation instructions to the streaming node 113 using the stream control transmission protocol.

[0116] The streaming node 113 is also used to receive cloud game operation instructions and forward the cloud game operation instructions to the cloud game service node 112 through the stream control transmission protocol.

[0117] The cloud game service node 112 is also used to receive and respond to cloud game operation instructions, and send response data corresponding to the cloud game operation instructions to the streaming node 113.

[0118] The streaming node 113 is also used to receive response data fed back by the cloud gaming service node 112 and send the response data to the first access node.

[0119] The first access node is further configured to receive response data sent by the streaming node and send the response data to the first player client 131 .

[0120] The first player client 131 is further configured to receive the response data sent by the first access node and play the game screen corresponding to the response data.

[0121] After the first player client 131 obtains and plays the game screen corresponding to the target cloud game data stream, the user can control the cloud game through the first player client 131, such as clicking, dragging, and other operations on props, characters, and other objects in the game screen. The first player client 131 responds to the cloud game operation instruction and sends the cloud game operation instruction to the push stream node 113 through the first access node using the SCTP (Stream Control Transmission Protocol) protocol. After receiving the cloud game operation instruction, the push stream node 113 forwards the cloud game operation instruction to the cloud game service node 112 through the SCTP protocol, so that the cloud game service node 112 responds to the cloud game operation instruction, and feeds back the response data corresponding to the cloud game operation instruction to the push stream node 113, and further forwards it to the first access node. The first access node then forwards the response data to the first player client 131, and the first player client 131 plays the game screen corresponding to the response data.

[0122] In one example, the response data of the cloud gaming service node 112 to the cloud gaming operation instruction is also transmitted via the SCTP protocol. Specifically, when data is transmitted between nodes, the cloud gaming operation instruction or the response data of the cloud gaming operation instruction can be placed in the SCTP protocol for transmission to achieve reliable data transmission.

[0123] In an example, when the streaming node 113 and the first access node coincide with each other, the streaming node 113 may directly forward the response data to the first player client 131 after receiving the response data.

[0124] Similarly, the user of the invited player client can also perform similar operations as the user of the above-mentioned player client to obtain and play the game screen corresponding to the response data forwarded by the relay node from the second access node.

[0125] In an embodiment of the present invention, users can control cloud games, and the cloud game service node can respond to the user's cloud game operation instructions, and forward the response data corresponding to the cloud game operation instructions to the access node closest to the player client through the streaming node, so that the player client can obtain and play the game screen corresponding to the response data from the access node. The cloud game operation instructions are transmitted in the SCTP protocol, realizing reliable data transmission.

[0126] For example, Figure 3 As shown, the cloud game service node can be a cloud phone, and the cloud game client (i.e., the player client) allocates the system ( Figure 3 The SFU node allocation system receives the cloud game access request and allocates the nearest access node ( Figure 3 (not shown). The player client responds to the cloud game control command by sending it to the cloud phone via the access node. The cloud phone responds to the cloud game control command by sending the target cloud game data stream to the streaming SFU node. The streaming SFU node receives the target cloud game data stream and sends it to the player client. The player client then plays the game screen corresponding to the target cloud game data stream. The target cloud game data stream is an RTC data stream, and the cloud game control command and the target cloud game data stream are transmitted via the SCTP protocol.

[0127] The player client can also send a request to at least one invited cloud game client (i.e., the invited player client, Figure 3The invited player client receives the invitation information and sends a joining request to the SFU node allocation system. The SFU node allocation system receives the joining request and allocates the nearest access node to the invited player client based on the identification information of the invited player client carried in the joining request. The invited player client sends the flow information to the nearest access node corresponding to it. After receiving the flow information, the nearest access node queries the routing table to obtain the flow link corresponding to the flow information, and sends the flow information to the target transfer node ( Figure 3 The target transfer node receives the stream information and sends the stream information to the push SFU node. The push SFU node receives the stream information and sends the target cloud game data stream corresponding to the stream information to the target transfer node. The target transfer node sends the target cloud game data stream to the nearest access node corresponding to the invited player client, and then the nearest access node forwards it to the invited player client. The invited player client plays the game screen corresponding to the target cloud game data stream. Among them, the joining invitation information, joining request, stream information and target cloud game data stream can all be transmitted through the SCTP protocol.

[0128] The push stream SFU node can also convert the RTC data stream into RTMP data stream and send the RTMP data stream to the CDN node, and then the viewing client ( Figure 3 (not shown) can obtain RTMP data stream from the CDN node and play the game screen corresponding to the RTMP data stream to achieve live broadcast of cloud games, etc.

[0129] After the player client obtains and plays the game screen corresponding to the target cloud game data stream, the user can control the cloud game through the player client. The player client responds to the cloud game operation instruction and sends the cloud game operation instruction to the push stream SFU node through the access node closest to it. After receiving the cloud game operation instruction, the push stream SFU node forwards the cloud game operation instruction to the cloud phone so that the cloud phone responds to the cloud game operation instruction, and feeds back the response data corresponding to the cloud game operation instruction to the push stream SFU node, and further forwards it to the access node closest to the player client. The access node closest to the player client then forwards the response data to the player client, and the player client plays the game screen corresponding to the response data. Similarly, after the invited player client obtains and plays the game screen corresponding to the target cloud game data stream, it can also control the cloud game. The difference is that the cloud game operation instruction of the invited player client needs to be transferred through the transfer SFU node. The rest of the interaction process is similar to that of the player client, and the embodiments of the present invention will not be repeated here.

In this process, the first player client interacts with the cloud game service node through the first access node allocated to it by the node allocation system, sends cloud game control instructions to the cloud game service node, and then the cloud game service node feeds back the target cloud game data stream to the first player client via the push node, so that the target cloud game data stream is transmitted through the cascade link between the nodes.
