[0185] In addition, the embodiments of this application can be applied to communication systems such as 4G, 5G, and 6G.

[0186] In this application embodiment, the following problems need to be solved:

[0187] Scenario 1: In XR, video stream data can be categorized into intra-picture (I) frames, predictive (P) frames, and bi-directional interpolated prediction (B) frames. I-frames are also called independently decoded frames. Frames between I-frames are either P-frames or B-frames. The I-frame associated with a P-frame or B-frame is the I-frame that is closest to that P-frame or B-frame in the timeline. Since decoding is impossible without I-frames, but I-frames can be decrypted independently even without non-I-frames, I-frames are more important than non-I-frames. The QoS requirements for I-frames and non-I-frames can differ. For example, I-frames have a higher priority than non-I-frames. The transmission rate of non-I-frames can be higher than that of I-frames.

[0188] Therefore, when an XR service data is mapped to multiple QoS streams, the following issues still need to be addressed:

[0189] Question 1: When mapped to multiple QoS streams, for example: the first QoS stream is used to carry I-frames; the second QoS stream is used to carry non-I-frames. If the transmission of an I-frame fails, continuing to transmit non-I-frames associated with that I-frame becomes meaningless. However, when I-frames and non-I-frames are mapped to different QoS streams, it becomes unclear which I-frames are associated with which non-I-frames.

[0190] Question 2: When a communication network receives I-frames and non-I-frames, if some I-frames are lost, the non-I-frames associated with the lost I-frames will not be recognized.

[0191] One solution is to have non-I-frame data packets carry the sequence number of the associated I-frame. This way, by using the sequence number of the associated I-frame carried by the non-I-frame data packets, it's possible to identify whether the associated I-frame of the non-I-frame is lost. Therefore, if the associated I-frame is lost, the non-I-frame can be discarded or not sent, thus preventing the non-I-frame associated with the lost I-frame from going undetected.

[0192] Another approach is to have the first data carry a timestamp, the second data carry a timestamp, and the second data between two consecutive first data sets is associated with the first data; there is a maximum time interval between the two first data sets, and any interval exceeding the maximum time interval indicates that the first data has been lost. For example, I-frame data packets (hereinafter referred to as I-frame data packets) carry timestamps, and non-I-frame data packets (hereinafter referred to as non-I-frame data packets) carry timestamps. The non-I-frame data packets between two consecutive I-frame data packets are associated with the I-frame data packets, and there is a maximum time interval between the two I-frame data packets. In this case, if the interval between the two I-frame data packets exceeds the maximum time interval, it indicates that the I-frame has been lost. Therefore, in the event of an I-frame loss, the associated non-I-frame can be discarded or not sent, thus preventing the non-I-frame associated with the lost I-frame from being unidentifiable.

[0193] Scenario 2: In XR applications, there is data for both the left and right eyes, and this data needs to be scheduled together. The left and right eye data have equal importance. However, although timestamps have been added to the left and right eye data, it may only be quasi-synchronous, meaning there is a certain offset.

[0194] Therefore, when an XR service data is mapped to multiple QoS streams, the following issues still need to be addressed:

[0195] Question 3: When mapped to multiple QoS streams, how to ensure that the data from the left and right eyes are sent simultaneously? For example, the left-eye frame data packet carries a timestamp, and the right-eye frame data packet carries a timestamp. In this way, the timestamps can be used to coordinate the scheduling of left-eye and right-eye frame data packets mapped to different QoS streams, thereby ensuring that the data from the left and right eyes are sent simultaneously.

[0196] Scenario 3: In holographic communication, multiple QoS streams exist and require synchronization. For example, these multiple QoS streams may have equal importance level labels. Furthermore, these multiple QoS streams may belong to different terminals. Different terminals may be served by the same RAN or by multiple RANs.

[0197] One operational behavior can be: time-stamp synchronization scheduling, that is, data packets with the same timestamp, or within the same timestamp stickiness interval, need to be scheduled for synchronization. For example, data packets mapped to multiple QoS flows carry the same timestamp, so the data packets of these multiple QoS flows can be synchronized and scheduled using the same timestamp; or, data packets mapped to multiple QoS flows carry different timestamps, but these different timestamps are within the same timestamp stickiness interval, in which case the data packets of these multiple QoS flows can be synchronized and scheduled. The communication terms involved in the embodiments of this application are described below.

[0198] In one embodiment of the present invention, data and data packet represent the same meaning and can be used interchangeably.

[0199] In one embodiment of the present invention, the description information of the data channel includes: information for identifying the data channel. When the data channel is a QoS flow, the description information of the data channel may be at least one of the following: QoS flow identifier, 5QI.

[0200] In one embodiment of this application, the data channel may include, but is not limited to, one of the following: PDU session, PDN connection, QoS stream, bearer, Internet Protocol Security (IPsec) channel, wherein the bearer may be an evolved radio access bearer (E-RAB), a radio access bearer (RAB), a data radio bearer (DRB), a signalalling radio bearer (SRB), etc.

[0201] In one embodiment of this application, the first header is the header of the first protocol.

[0202] In one embodiment of this application, the first protocol is an interface protocol between a first communication device and a second communication device.

[0203] In one implementation, when the first communication device is a RAN network element and the second communication device is a gateway, the interface protocol between the first and second communication devices can be the interface protocol between the RAN network element and the gateway, such as the NG interface user plane interface protocol, GTP-U. The first protocol header can be a GTP-U Container. GTP stands for GPRS Tunneling Protocol.

[0204] In one embodiment, when the first communication device is a RAN network element and the second communication device is a terminal, the interface protocol between the first communication device and the second communication device can be the interface protocol between the RAN network element and the terminal, such as RRC.

In one embodiment, the first type may be referred to as a key type.

[0208] In one optional embodiment of this application, a data frame may include one or more data packets with the same content or consecutive data packets, such as: I-frame, non-I-frame, P-frame, B-frame, left-eye frame, and right-eye frame.

[0212] In one embodiment, the information used to identify the importance level includes: an importance level number (e.g., the Nth importance level). In one embodiment, the larger the importance level number, the higher the importance level; in another embodiment, the smaller the importance level number, the lower the importance level.

[0213] In one implementation, the importance level is referred to as priority.

[0214] In one optional embodiment of the present invention, the datasets that are associated with the first dataset include: datasets that depend on the first dataset.

[0229] (3) In one embodiment, the second header information refers to the header of the second protocol of the data packet. When the second protocol is the MPEG protocol, the second header information can be the NAL (Network Abstraction Layer) of the MPEG protocol.

[0230] In one implementation, it can be determined whether the data is the first data by judging the data feature information in the second header information of the data packet.

[0231] In one implementation, the data feature information can be obtained from the second packet header information. For example, for an I-frame, it can be obtained by reading the NAL header of the MPEG protocol.

For example, if the data packet structure corresponding to an I-frame is IP (TCP (MPEG)), then the protocol layer information to which the data feature information belongs is the third layer, the protocol information to which the data feature information belongs is the MPEG protocol, and the header information corresponding to the data feature information is an I-frame. Based on the protocol layer information to which the data feature information belongs, the data packet can be identified as an I-frame.

[0235] When data A is a data frame, the association information of the data includes: the reference frame information of data A. For example, the reference frame of a P frame is an I frame.

[0236] In one optional embodiment of this application, the association relationship includes at least one of the following: dependency relationship, being depended upon relationship.

In another optional embodiment of this application, the communication module may include a chip for communicating with the network. The control plane signaling includes at least one of the following: NAS signaling, AS layer signaling (also known as RRC signaling).

[0242] In another implementation, the information obtained by the terminal from the control plane signaling of the communication network can be information generated by the communication network. This information needs to be sent to the application server by the application client through the application layer. It is easy to understand that information sent through the application layer can be packaged into user plane data in the communication network, thus reducing the impact on the control plane interface.

[0243] In one alternative embodiment of this application, the dataset may also be referred to as one of the following: data segment, data frame, application data.

[0244] In one implementation, the dataset mapping rule in the data channel mapping rule is the dataset mapping rule within the data channel.

In another optional embodiment of this application, the communication module may include a chip for communicating with the network.

[0258] In another implementation, the information obtained by the terminal from the control plane signaling of the communication network can be information generated by the communication network. This information needs to be sent to the application server by the application client through the application layer. It is easy to understand that information sent through the application layer can be packaged into user plane data in the communication network, thus reducing the impact on the control plane interface.

[0259] In one optional embodiment of this application, the first data includes I-frame data; the second data includes non-I-frame data packets, such as P-frame and / or B-frame data packets.

[0260] In one optional embodiment of this application, the description information of the first data channel includes at least one of the following: I-frame, important, equal, importance level. The description information of the second data channel includes at least one of the following: non-I-frame, minor, equal, importance level.

The information of the data channel group includes: a group identifier for the data channel group, and identifiers of the data channels contained within the data channel group.

[0265] The data control method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0266] Please see Figure 2 , Figure 2 This is a flowchart of a data control method provided in an embodiment of this application. The method is applied to a first communication device; the first communication device includes, but is not limited to, a RAN network element. Figure 2 As shown, the method includes the following steps:

[0267] Step 21: The first communication device acquires the first information and / or index information used to indicate the value of the first information.

[0268] Optionally, the first information may include at least one of the following:

[0269] Data packet description information;

[0270] Data channel association information;

[0271] Data set association information;

[0272] First operation instruction information.

[0273] Step 22: The first communication device performs QoS control operations based on the first information and / or index information used to indicate the value of the first information.

[0274] In one embodiment, the first communication device may receive the aforementioned first information and / or index information used to indicate the value of the first information from a core network element (such as a UPF) or a terminal.

[0275] In one embodiment, the index information used to indicate the value of the first information may be an index information of the value of the first information, through which the first information can be determined.

[0276] In another implementation, the first information can be determined based on index information used to indicate the value of the first information.

[0277] Optionally, the QoS control operation includes at least one of the following:

[0278] To discard or not send data packets;

[0279] Perform coordinated scheduling operations on data packets;

[0280] Reorder the data packets;

[0281] Data packets are sent according to their importance level.

[0282] It's easy to understand that 1) by discarding or not sending data packets based on the first information and / or the index information used to indicate the value of the first information, the associated data packets can be prevented from being unidentified, thereby improving data operation performance. For example, based on dataset association information and / or data channel association information, if an I-frame data packet in a dataset is lost or fails to be sent, the associated non-I-frame data packets can be discarded or not sent, thus preventing the non-I-frames associated with the lost I-frame from being unidentified.

[0283] 2) By performing coordinated scheduling operations on data packets based on the first information and / or the index information used to indicate the value of the first information, synchronous scheduling of data packets mapped to different data channels can be achieved, thereby improving data operation performance. For example, based on the data description information of the data packets and / or the data channel association information, synchronous scheduling can be performed on data packets with synchronization requirements mapped to different data channels, such as left-eye frame data packets and right-eye frame data packets, thereby ensuring that the data for the left and right eyes are sent simultaneously.

[0284] 3) By reordering data packets based on the first information and / or the index information used to indicate the value of the first information, related data can be sent in sequence, reducing the possibility of data not being identifiable, and ensuring that data requiring synchronization is scheduled synchronously. For example, for left-eye frame data packets and right-eye frame data packets mapped to different data channels, the reordering operation can synchronize the left-eye frame data packets and right-eye frame data packets.

[0285] 4) Data packets are sent according to importance level based on the first information and / or the index information used to indicate the value of the first information. This ensures that data with higher importance level is sent first, and data with the same importance level is scheduled synchronously.

[0286] Optionally, the data description information of the data packet may include at least one of the following:

[0287] The data packet contains description information of the dataset to which it belongs and / or index information used to indicate the description information of the dataset;

[0288] Information used to identify the data packet;

[0289] The type information of the data packet;

[0290] The importance level of the data packet;

[0291] The timestamp information of the data packet.

[0292] Optionally, the descriptive information of the dataset may include at least one of the following:

[0293] Information used to identify the dataset;

[0294] Importance level information of the dataset;

[0295] The type information of the dataset;

[0296] The label information of the dataset;

[0297] The sequence number of the dataset.

[0298] In one implementation, the dataset consists of one or more data packets. When two data packets have the same dataset sequence number, the importance levels of the two data packets may be different or the same.

[0299] In one implementation, the two data packets may have the same dataset type, but the sequence numbers of the datasets may be different. For example, in the frame sequence IPBIPPI, the first, fourth, and seventh frames correspond to datasets for I-frame types, but the sequence numbers of these datasets may be different, such as 1, 2, and 3.

[0300] In one implementation, a dataset can be used to map data from one or more data frames.

[0301] In one implementation, a data frame may consist of one or more data packets.

[0302] In one implementation, data of different importance levels in a dataset can be mapped to different data channels (such as QoS streams).

[0303] In another implementation, different datasets can be mapped to different data channels (such as QoS streams).

[0304] Optionally, the information used to identify the dataset includes at least one of the following:

[0305] Index information used to indicate the descriptive information of the dataset;

[0306] Importance level information of the dataset;

[0307] The type information of the dataset;

[0308] The label information of the dataset.

[0309] The sequence number of the dataset.

[0310] In one embodiment, the index information used to indicate the description information of the dataset may be the index information of the dataset's description information values, through which the description information of the dataset can be determined.

[0311] In one implementation, different datasets have different importance levels, so the datasets can be identified using their importance level information. It's easy to understand that data within a data channel can belong to datasets with different importance levels, so the data can be identified using the dataset's importance level information.

[0312] In another implementation, different datasets may have the same importance level. In this case, the datasets cannot be identified by their importance level information.

[0313] In one implementation, importance level information is distinguished by different importance level numbers.

[0314] In one implementation, the data channel includes a QoS stream.

[0315] (1) In one embodiment, different types of data frames can map different datasets, and the different datasets have different sequence numbers. For example, the sequence number of the data frame IPBIPPI is I-1, P-1, B-1, I-2, P-2, P-3, I-3.

[0316] (2) In another implementation, different types of data frames can be mapped to the same type of dataset, such as P frames and B frames can be mapped to datasets used for non-I frames.

[0317] Furthermore, in one implementation, different data frames mapped to the same type of dataset have different dataset sequence numbers. For example, the sequence number of the data frame IPBIPPI is I-1, not I-1, not I-2, I-2, not I-3, not I-4, I-3.

[0318] Furthermore, in another implementation, data frames of different types mapped to the same type of dataset have the same dataset sequence number. For example, the sequence number of the data frame IPBIPPI is 1,2,2,2,1,2,2,1.

[0319] (4) In another implementation, data frames of different types but with a relationship (such as a dependency relationship) are mapped to a dataset. For example, the number of the data frame sequence IPBIPPI can be 1,1,1,2,2,2,3.

[0320] Optionally, the data channel association information may include at least one of the following:

[0321] Description information of the data channels that data channel A depends on;

[0322] Description information of the data channel that depends on data channel A;

[0323] Descriptive information about data channels that are related;

[0324] Description information of the data channel group;

[0325] The data channel group includes two or more data channels that are related to each other.

[0326] In one embodiment, the data channel A can be one of the following: any data channel of the terminal, or a data channel carrying the data of the dataset.

[0327] Optionally, the dataset association information may include at least one of the following:

[0328] Descriptive information about the datasets that dataset A depends on;

[0329] Descriptive information about the dataset that depends on dataset A;

[0330] Descriptive information about the dataset to which the data packet belongs;

[0331] Descriptive information about datasets that have relationships;

[0332] Descriptive information about the dataset group;

[0333] The dataset group contains two or more datasets that are related.

[0334] In one implementation, the data channel A can be one of the following: any dataset, the dataset to which the data packet belongs.

[0335] In one implementation, taking dataset A as an example, the dataset associated with dataset A includes at least one of the following: the dataset that dataset A depends on, and the dataset that depends on dataset A.

[0336] For example, if dataset A is used for non-I-frame data, dataset B can be used for I-frame data. In this case, dataset B is a dataset that depends on dataset A.

[0337] For example, if dataset A is used for I-frames, dataset B can be used for non-I-frames. In this case, dataset B is the dataset that dataset A depends on.

[0338] For example, dataset A contains data for the left eye, and dataset B contains data for the right eye. There is a correlation between dataset A and dataset B. That is, dataset A can be associated with dataset B; and vice versa.

[0339] Optionally, the first operation instruction information includes: operation information; or,

[0351] The fourth data is the data in the fourth data channel.

[0352] The data in the third dataset is the data in the third data channel.

[0353] The data in the fourth dataset is the data in the fourth data channel.

[0354] Optionally, the description information of the third data and the description information of the fourth data can be used to indicate that in the event of loss or failure of transmission of the third data, the fourth data should be discarded or not transmitted; this can prevent the fourth data associated with the lost or failed third data from being unidentified, thereby improving data operation performance.

[0355] And / or,

[0356] The descriptive information of the third data can be used to indicate that, in the event of loss or failure of the third data, data in the fourth data channel that meets at least one of the following conditions should be discarded or not transmitted: other data in the same dataset that depends on the third data; other data in the same dataset that is associated with the third data; other data in the same dataset; other data in the same dataset whose importance level is lower than that of the third data; wherein, the same dataset is the dataset to which the third data belongs; thereby avoiding the inability to identify the fourth data associated with the lost or failed third data, thereby improving data operation performance.

[0359] And / or,

[0360] The descriptive information of the third dataset and the fourth dataset can be used to indicate that if the third dataset is lost or fails to be sent, the data in the fourth dataset should be discarded or not sent.

[0363] And / or,

[0364] The descriptive information of the fourth dataset can be used to indicate that, in the event that a dataset satisfying the second condition in the third data channel is lost or fails to be transmitted, the data of the fourth dataset should be discarded or not transmitted; wherein, the second condition includes at least one of the following: the dataset on which the fourth dataset depends; the dataset associated with the fourth dataset; the dataset with a higher importance level than the fourth dataset; thereby avoiding the failure to identify the fourth data associated with the lost or failed third data, thereby improving data operation performance.

[0390] In one implementation, the left-eye frame and the right-eye frame are mapped to the same dataset. The first data can be of a first type, such as the data for the left-eye frame, and other data associated with the first data can be of a second type, such as the data for the right-eye frame.
