[0058] The present application will be further described in detail below with reference to the drawings and embodiments.

[0059] The embodiments of the present application provide a transmission method for a data stream service, which is applied to a second network device, as Figure 1 shown, and the method includes:

[0060] S101: Receive a first message sent by a first network device.

[0061] Among them, the first message includes the association relationship information between the service bearer and the computing power bearer of the data stream service, and the first message indicates a handover transmission of the data stream service.

[0062] It can be understood that the multi-stream service may include a scenario where data information collected by multiple terminals interacts with a base station through a communication device. For example, a user equipment (UE) interacts with the base station; it may also include a scenario where a communication terminal with multiple communication modules simultaneously interacts with the base station. For example, video streams, audio streams, tactile streams, control streams, etc. of a virtual reality (VR) device.

[0063] When the communication device or communication terminal is moving, switching the multi-stream service data to the same base station in the same cell can achieve synchronous transmission of the multi-stream service in the communication system. The first network device may be a communication base station. Exemplarily, the first network device is the first base station, and the first base station can be understood as the source base station, that is, the base station that interacts with the multi-stream service data before the multi-stream service data is switched. The second base station receives the first message, and the second base station can be understood as the target base station, that is, the base station that receives the multi-stream data service switch.

[0064] In practical applications, before the multi-stream service data is switched, the source base station may send a handover request (HandoverRequest / HandoverRequired) message to the target base station through the Xn interface, requesting the target base station to perform a multi-stream service switch. The first message can be understood as a handover request message, and the handover request message includes the association relationship information between the service bearer and the computing power bearer of the data stream service; the association relationship information includes the association relationship between the service bearer and the computing power bearer of each stream. This association relationship can also be called a binding relationship, which indicates the computing power bearer required during the transmission of each service stream.

[0065] Exemplarily, the computing power bearer may include graphics processing unit (GPU) computing power information, CPU computing power information, etc., and may also include the number of floating-point calculations per second, the number of central processing unit (CPU) cores, the number of GPU cores, the number of computing units, the computing frequency, etc. The association relationship information may include the association relationship between the service bearer and the computing power bearer of a single service stream of a UE, may also include the association relationship between the service bearers and the computing power bearers of multiple service streams of a UE, and may also include the association relationship between the service bearers and the computing power bearers of multiple service streams of multiple UEs. This application does not make specific limitations on this.

[0066] S102: Perform handover transmission on the data stream service based on the association relationship information.

[0067] It can be understood that after receiving the association relationship information between the service bearer and the computing power bearer of the data stream service, the second base station can perform service switching according to its own computing power or scheduling resources.

[0068] In practical applications, when the computing power bearer or scheduling resources of the second base station are sufficient, the second base station can receive all multi-stream services; when the computing power bearer or scheduling resources of the second base station are limited, the second base station can receive some service flows or receive them after processing all service flows with reduced guarantee; when the computing power bearer or scheduling resources of the second base station cannot receive multi-stream services, service switching can be not performed; whether receiving all multi-stream services, receiving some multi-stream services or being unable to receive multi-stream services, the second base station can send corresponding messages to the first base station according to its own computing power or scheduling resources, indicating receiving all multi-stream services, receiving some multi-stream services or being unable to receive multi-stream services.

[0069] The transmission method of the data stream service provided by this application receives a first message sent by a first network device; the first message includes the association relationship information between the service bearer and the computing power bearer of the data stream service, and the first message indicates to switch the transmission of the data stream service; based on the association relationship information, perform switching transmission on the data stream service. That is to say, by receiving the first message sent by the first network device and performing switching transmission on the data stream service based on the association relationship information between the service bearer and the computing power bearer of the data stream service in the first message, the problem that the dimension considered in the multi-stream service switching process in the related art is relatively single, resulting in the failure of multi-stream service switching, is solved. This application regards the application bearer and the computing power bearer as a whole, thereby comprehensively considering the multi-dimensional association of data during multi-stream service switching, and then realizing the synchronous transmission of multi-stream services in the communication system and ensuring the transmission of multi-stream data during the movement process.

[0070] In one embodiment, the association relationship information includes one of the following:

[0071] The association relationship information between the service bearer and the computing power bearer of a single service flow of an associated terminal;

[0072] The association relationship information between the service bearers and the computing power bearers of multiple service flows of an associated terminal;

[0073] The association relationship information between the service bearers and the computing power bearers of multiple service flows of multiple associated terminals.

[0074] In practical applications, taking multiple service flows in a game scenario as an example, Flow 1 is the helmet display flow, and the required computing power load is a; Flow 2 is the large screen display flow, and the required computing power load is b; Flow 3 is the smartphone display flow, and the required computing power load is c. The association relationship information between the service load and the computing power load of a single service flow of an associated terminal refers to the association relationship between Flow 1 and the computing power load a, the association relationship between Flow 2 and the computing power load b, and the association relationship between Flow 3 and the computing power load c. The association relationship information between the service load and the computing power load of multiple service flows of multiple associated terminals may include the association relationship between Flows 1, 2, and 3, and may also include the association relationship between Flows 1 and 2, which is not exhaustively listed here.

[0075] Taking multiple service flows in a helmet video scenario as an example, Flow 1 is the audio stream, and the required computing power load is x; Flow 2 is the video stream, and the required computing power load is y. The association relationship information between the service load and the computing power load of multiple service flows of an associated terminal refers to the association relationship between Flows 1 and 2.

[0076] In one embodiment, the association relationship information of multiple service flows includes first information and second information; the first information indicates the association relationship between the service load and the computing power load of each service flow in the multiple service flows; the second information indicates the association relationship between a group of multi-flow services.

[0077] The source base station can obtain the association relationship information between the service load and the computing power load of the data stream service in two ways; one is that the UE carries and notifies the first base station through the UE Assistance Information (UAI) signaling, and the other is that the core network identifies the services of multiple flows and notifies the first base station through the Time Sensitive Communication Assistance Information (TSCAI).

[0078] Exemplarily, the first information can be represented by a set of associated identifiers Associated ID; the second information can be represented by a reference identifier Reference ID of a group of multi-flow services, or an application identifier Service ID of a group of multi-flow services, or a public identifier Public ID of a group of multi-flow services.

[0079] In practical applications, taking multiple service flows in a game scenario as an example, Flow 1 is the helmet display flow, and the required computing power load is a; Flow 2 is the large screen display flow, and the required computing power load is b; Flow 3 is the smartphone display flow, and the required computing power load is c. The association relationship between Flow 1 and the computing power load a can be represented by the Associated ID as 0-1; the association relationship between Flow 2 and the computing power load b can be represented by the Associated ID as 0-2; the association relationship between Flow 3 and the computing power load c can be represented by the Associated ID as 0-3. The first information includes Associated ID 0-1, Associated ID 0-2, and Associated ID 0-3.

[0080] The association relationships among a group of multi-flow services can include the association relationships among Flows 1, 2, and 3, and the Reference ID can be represented as 1; it can also include the association relationships between Flows 1 and 2, and the Reference ID can be represented as 2; it can also include the association relationships between Flows 2 and 3, and the Reference ID can be represented as 3. The second information includes Reference ID 1, Reference ID 2, and Reference ID 3.

[0081] In one embodiment, the first message further includes information related to multi-flow coordination; Step S102 can perform switching transmission on the data stream service based on the association relationship information, and can be implemented through the following steps:

[0082] Perform switching transmission on the data stream service based on the association relationship information and the information related to multi-flow coordination.

[0083] It can be understood that the information related to multi-flow coordination can include the Quality of Service (QoS) information of multi-flow services. The QoS information can include the overall QoS of multi-flow services, and can also include the sub-QoS of the service sub-flows of each service flow. Taking the multi-flow services in a video conferencing scenario as an example, the video conferencing includes a video stream and an audio stream. The overall QoS refers to the service quality of the overall video conferencing data stream; the sub-QoS is the service quality of the video stream data and the service quality of the audio stream data.

[0084] In practical applications, the data bearer of each sub - flow is associated with the corresponding computing bearer. The quality of service of multi - flow services can be used as the priority requirement for multi - flow service transmission. During the transmission process, sub - QoS indicates the corresponding data transmission priority. For example, in a multi - flow service of a video conference, if the audio stream has a higher priority than the video stream, the audio stream can be preferentially guaranteed according to the sub - QoS indication. When the computing resources or scheduling resources of the second base station are limited, the first base station can, according to the sub - QoS indication, downgrade the quality of service of the video stream of the second base station to ensure the handover of the entire video conference service.

[0085] In one embodiment, the relevant information for multi - flow coordination includes at least one of the following:

[0086] The relevant information for multi - flow coordination corresponding to each service flow in the data - stream service;

[0087] The relevant information for multi - flow coordination corresponding to each service sub - flow of each service flow in the data - stream service.

[0088] It can be understood that the relevant information for multi - flow coordination corresponding to each service flow in the data - stream service can be understood as the overall QoS; the relevant information for multi - flow coordination corresponding to each service sub - flow of each service flow in the data - stream service can be understood as sub - QoS.

[0089] In practical applications, for a Guaranteed Bit Rate (GBR) service, the relevant information for multi - flow coordination can also include the Alternative QoS of each service sub - flow of each service flow. During the handover process of the multi - flow service, the first base station sends the Alternative QoS to the second base station. When the computing resources or scheduling resources of the second base station are limited, the Alternative QoS can be used as an indication for selective downgrading.

[0090] In one embodiment, the relevant information for multi - flow coordination includes the first service quality level requirement. Based on the association relationship information and the relevant information for multi - flow coordination, performing handover transmission on the data - stream service includes:

[0091] When the service bearer and computing bearer of the second network device satisfy the association relationship, performing handover transmission on the data - stream service according to the first service quality level requirement.

[0092] It is understandable that different service flows correspond to different service quality requirements and transmission priorities. Taking the multi-flow service in a video conferencing scenario as an example, the video conferencing includes a video stream and an audio stream. The audio stream and the video stream respectively correspond to different service qualities, and the transmission priority of the audio stream is higher than that of the video stream. At this time, the first service quality level requirement can be understood as not degrading the service quality of the service sub-flows, and transmitting each service sub-flow in the multi-flow service according to the transmission priority.

[0093] In practical applications, that the service bearer and computing power bearer of the second network device satisfy the association relationship can be understood as that the computing power resources or scheduling resources of the second base station are sufficient. According to sub-QoS, the second base station can accept all multi-flow services according to the highest service quality and priority requirements.

[0094] In one embodiment, the method further includes:

[0095] When the service bearer and computing power bearer of the second network device satisfy the association relationship, sending a second message to the first network device; the second message indicates that the second network device receives all of the data stream service.

[0096] In practical applications, after the second base station completes the handover preparation, it can send a message of Handover Request Acknowledge to the first base station. The handover request message may include the result of accepting all multi-flow services, that is, the second message.

[0097] In one embodiment, the relevant information of multi-flow coordination includes the first service quality level requirement. Based on the association relationship information and the relevant information of multi-flow coordination, performing handover transmission on the data stream service includes:

[0098] When the service bearer and / or computing power bearer of the second network device does not satisfy the association relationship, receiving the data stream service according to a second service quality level requirement lower than the first service quality level requirement, or receiving some service sub-flows in the data stream service according to the first service quality level requirement; the first service quality level requirement corresponding to some service sub-flows is higher than the priority of the first service quality level requirement corresponding to the remaining service sub-flows in the data stream service.

[0099] It can be understood that the second service quality level requirement can be understood as downgrading all service sub - flows, or transmitting some service sub - flows with higher priorities according to the transmission priority. The relevant information of multi - flow coordination can also include delay information, that is, the maximum synchronization / async delay that can be tolerated between multi - flow synchronizations, which is used for the alignment and synchronization of multi - flows. This delay information can also be carried and sent through the quality of service information. The delay information indicates the maximum synchronization / async delay for the second base station to align multiple service sub - flows, which can be used as a criterion for the second base station to accept multi - flow services. After the second base station receives the association relationship information and the delay information, the second base station can choose to accept multi - flow data with a smaller synchronization delay and reject multi - flow data with a larger synchronization delay.

[0100] In practical applications, when the service bearer and / or computing power bearer of the second network device do not meet the association relationship, it can be understood that the computing power resources or scheduling resources of the second base station are limited. The second base station can accept some service sub - flows with higher priorities according to sub - QoS or Alternative QoS and the delay information, or downgrade all service sub - flows and accept all of them.

[0101] In one embodiment, the method further includes:

[0102] When the service bearer and / or computing power bearer of the second network device do not meet the association relationship, send a third message to the first network device; the third message indicates a part of the data stream service received by the second network device; or, the third message indicates that the second network device reduces the service quality level of all of the data stream service and receives all of the data stream service.

[0103] In practical applications, after the second base station completes the handover preparation, it can send a handover request confirmation message to the first base station. The handover request message can also include the result of downgrading all service sub - flows and accepting all of them or accepting some service sub - flows with higher priorities, that is, the third message.

[0104] In one embodiment, the method further includes:

[0105] Based on the association relationship information and the relevant information of multi - flow coordination, prohibit the execution of handover transmission for the data stream service.

[0106] In practical applications, when the computing power resources or scheduling resources of the second base station cannot accept multi - flow services, the second base station can not perform the handover of multi - flow services according to the association relationship information and the relevant information of multi - flow coordination.

[0107] In one embodiment, after prohibiting the execution of handover transmission for the data stream service based on the association relationship information and the relevant information of multi - flow coordination, the method further includes:

[0108] Send a fourth message to the first network device; the fourth message indicates that the second network device fails in the handover of the data stream service.

[0109] If the fourth message indicates that the second network device cannot accept the handover request, the handover request is rejected.

[0110] In practical applications, when the computing power resources or scheduling resources of the second base station cannot accept multi-stream services, the second base station may send a message of Handover Preparation Failure, that is, the fourth message, to the first base station, for indicating the inability to accept multi-stream services.

[0111] In one embodiment, the fourth message includes third information, and the third information indicates the reason for the failure of the second network device in the handover of the data stream service.

[0112] In practical applications, when the second base station sends a handover preparation failure message to the first base station, it may also send a Cause Message to explain whether the handover failure is caused by limited computing power or limited communication resources. The third information can be understood as the Cause Message.

[0113] It can be seen from the above that this application changes the changes in network functions and configurations, so that the network can perceive the transmission association requirements of services, and realizes the transmission of services such as large bandwidth, low latency, and high reliability by the network.

[0114] An embodiment of this application provides a method for transmitting a data stream service, which is applied to a first network device, as Figure 2 shown, the method includes:

[0115] S201: Send a first message to the second network device; the first message includes the association relationship information between the service bearer and the computing power bearer of the data stream service, and the first message indicates the handover transmission of the data stream service.

[0116] It can be understood that the second network device is the second base station, and the second base station can be understood as the target base station, that is, the base station that receives the handover of multi-stream data services. The first base station that sends the first message can be understood as the source base station, that is, the base station that interacts with the multi-stream service data before the multi-stream service data is handed over.

[0117] The transmission method for data flow services provided by this application is that a first network device sends a first message to a second network device; the first message includes the association relationship information between the service bearer and the computing power bearer of the data flow service, and the first message indicates a handover transmission for the data flow service. That is, the first network device sends a first message to the second network device, requesting the second network device to perform a handover process. The first message serves as a handover request message and includes the association relationship information between the service bearer and the computing power bearer of the data flow service. In this way, when the second network device receives the first message, it performs a handover operation based on this association relationship information, solving the problem in the related art that the dimensions considered in the multi-flow service handover process are relatively single, resulting in the failure of the multi-flow service handover. This application regards the application bearer and the computing power bearer as a whole, thereby comprehensively considering the multi-dimensional association of data during the multi-flow service handover, and then realizing the synchronous transmission of multi-flow services in the communication system, ensuring the transmission of multi-flow data during the movement process.

[0118] In one embodiment, the association relationship information includes one of the following:

[0119] The association relationship information between the service bearer and the computing power bearer of a single service flow of an associated terminal;

[0120] The association relationship information between the service bearers and the computing power bearers of multiple service flows of an associated terminal;

[0121] The association relationship information between the service bearers and the computing power bearers of multiple service flows of multiple associated terminals.

[0122] In one embodiment, the association relationship information of multiple service flows includes first information and second information; the first information indicates the association relationship between the service bearer and the computing power bearer of each service flow in the multiple service flows; the second information indicates the association relationship between a group of multi-flow services.

[0123] In one embodiment, the first message further includes relevant information on multi-flow coordination.

[0124] In one embodiment, the relevant information on multi-flow coordination includes at least one of the following:

[0125] The relevant information on multi-flow coordination corresponding to each service flow in the data flow service;

[0126] The relevant information on multi-flow coordination corresponding to the service sub-flows of each service flow in the data flow service.

[0127] In one embodiment, the relevant information on multi-flow coordination includes a first service quality level requirement.

[0128] In one embodiment, before step S201 of sending the first message to the second network device, the method further includes:

[0129] Receive the association relationship information sent by the associated terminal and / or the third network device.

[0130] In practical applications, the source base station can obtain the association relationship information between the service bearer and the computing power bearer of the data stream service in two ways; one is that the UE carries and informs the first base station through the UAI signaling, and the other is that the core network identifies multiple streams of services through the AF and carries and informs the first base station through the TSCAI. The third network device can be understood as the core network.

[0131] In one embodiment, the method further includes:

[0132] Receive a second message sent by the second network device; the second message indicates that the second network device receives all of the data stream service.

[0133] In practical applications, the computing power resources or scheduling resources of the second base station are sufficient. According to the sub-QoS, the second base station can accept all multi-stream services according to the highest service quality and priority requirements. After the second base station completes the handover preparation, the first base station can receive a handover request confirmation message sent by the second base station. The handover request message may include the result of accepting all of the multi-stream services, that is, the second message.

[0134] In one embodiment, the method further includes:

[0135] Receive a third message sent by the second network device; the third message indicates that the second network device receives a part of the data stream service; or, the third message indicates that the second network device reduces the service quality level of all of the data stream service and receives all of the data stream service.

[0136] In practical applications, the computing power resources or scheduling resources of the second base station are limited. The second base station can accept a part of the service sub-streams with higher priority according to the sub-QoS or Alternative QoS and the delay information, or perform a downgrading process on all of the service sub-streams and accept all of them. After the second base station completes the handover preparation, it can send a handover request confirmation message to the first base station. The handover request message may also include the result of performing a downgrading process on all of the service sub-streams and accepting all of them or accepting a part of the service sub-streams with higher priority, that is, the third message.

[0137] In one embodiment, the method further includes:

[0138] Transmit the data stream service to the second network device.

[0139] In one embodiment, the method further includes:

[0140] Receive a fourth message sent by the second network device; the fourth message indicates that the handover of the data stream service by the second network device fails.

[0141] When the first network device receives the fourth message sent by the second network device, and the fourth message indicates that the second network device cannot accept the handover request, the handover request is rejected. In this way, the following situations are avoided: it may cause waste of resources of the first network device, may also cause out-of-synchronization of multi-stream services, and increase the possibility of handover failure.

[0142] In practical applications, when the computing power resources or scheduling resources of the second base station cannot accept multi-stream services, the second base station may send a handover preparation failure message, that is, the fourth message, to the first base station to indicate that it cannot accept multi-stream services.

[0143] In one embodiment, the fourth message includes third information, and the third information indicates the reason for the failure of the second network device to switch the data stream service.

[0144] In practical applications, when the second base station sends a handover preparation failure message to the first base station, it may also send a cause message to explain whether the handover failure is caused by limited computing power or limited communication resources. The third information can be understood as the cause message.

[0148] 2. The first base station receives the association information sent by the terminal and sends a handover request to the second base station.
