[0107] Figure 1 FIG. 1 is a schematic diagram showing an architecture of a communication system according to an exemplary embodiment. Figure 1 As shown, the communication system 100 includes a terminal 101, an access network device 102, and a core network device 103. In some embodiments, the access network device 102 may include: a first access network device 1021 and a second access network device 1022.

[0108] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited to these.

The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

[0112] In some embodiments, the core network device 103 may be a device including a first network element, etc., or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0113] In some embodiments, the first network element is, for example, an access and mobility management function (AMF).

[0114] In some embodiments, the first network element is used for access and mobility management, such as registration management, connection management, and mobility management, etc., but the name is not limited thereto.

[0115] In some embodiments, the first network element is, for example, a user plane function (UPF).

[0116] In some embodiments, the first network element is used for data forwarding and traffic statistics on the user plane. The name is not limited thereto.

[0117] In some embodiments, the first network element is, for example, a session management function (SMF).

[0118] In some embodiments, the first network element is used for PDU session management, for example, PDU session creation, PDU session release, etc., the name is not limited thereto.

[0119] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. A person skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0120] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100, or a portion thereof, is shown but is not limited thereto. Figure 1 The various entities shown are examples, and the communication system may include Figure 1 All or part of the subject, and may also include Figure 1 For entities other than the above, the number and form of each entity are arbitrary, and the connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0121] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0122] At present, in the research of XR, the base station will obtain the information of the arrival of the data packet from the core network for reasonable scheduling and power saving. For example, the core network provides XR traffic auxiliary information (applicable to guaranteed bit rate (GBR) and non-GBR QoS flows) to the base station through the New Generation Application Protocol (NGAP) and Time Seneitive Communication Assistance Information (TSCAI). The XR traffic auxiliary information includes: periodic parameters of uplink data and / or periodic parameters of downlink data; N6 jitter information related to the periodic parameters of downlink data (i.e., between UPF and data network). The base station can use XR traffic auxiliary information to configure discontinuous reception (DRX) to better achieve terminal energy saving.

[0123] In some embodiments, the core network considers carrying relevant parameters in the user plane General Packet Radio Service Tunnelling Protocol for the User Plane (GTP-U) header, because carrying relevant parameters in the GTP-U header can more dynamically indicate the changes of the above parameters. For example, the periodic parameters are carried in the GTP-U header. However, when the base station receives the parameters in the TSCAI and the parameters in the GTP-U header, how the base station handles it is a problem.

[0124] In addition, although the GTP-U header of the data packet between the Xn interface can carry some information when the cell is switched, when the data packet carrying dynamic indication information sent from the core network is prepared to be sent to the terminal but not forwarded to the target base station, the target base station still cannot receive the data packet carrying dynamic indication information sent by the core network, resulting in inconsistent understanding of the target base station during the cell switching process, so this problem needs to be handled.

[0125] Figure 2A is an interactive schematic diagram of a communication method according to an exemplary embodiment Figure 1 .like Figure 2A As shown, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The communication method may include:

[0126] Step S2101: The core network device sends the second value of the first parameter through the control plane.

[0127] In some embodiments, the core network device sends the second value of the first parameter to the first access network device via a control plane. In some embodiments, the core network device sends the second value of the first parameter to the second access network device via a control plane. In some embodiments, the core network device sends the second value of the first parameter to the first access network device and the second access network device via a control plane, respectively.

[0128] In some embodiments, the first access network device receives the second value of the first parameter via a control plane. In some embodiments, the second access network device receives the second value of the first parameter via a control plane.

[0129] In some embodiments, the first access network device may be an access network device corresponding to a current serving cell of the terminal. In some embodiments, the first access network device may be an access network device corresponding to a primary cell of the terminal.

[0130] In some embodiments, the first access network device may be various types of base stations. For example, the first access network device may be an eNB, a base station in a 6G communication system, etc.

[0131] In some embodiments, the second access network device may be an access network device corresponding to the target cell. Exemplarily, in a cell switching scenario of a terminal, the first access network device may be an access network device corresponding to a source cell (the access network device accessed before the terminal switched, i.e., the source base station), and the second access network device may be an access network device corresponding to a target cell (the access network device accessed after the terminal switched, i.e., the target base station). In some embodiments, in a terminal dual connection scenario, the first access network device may be a primary node in the dual connection, and the second access network device may be a secondary node in the dual connection.

[0132] It should be noted that the access network device corresponding to the master node (i.e., the first access network device) can be an access network device that provides services to the terminal when the terminal changes from a single connection state to a dual connection state. The access network device corresponding to the master node is responsible for establishing a control plane connection with the core network device, transmitting signaling messages, and deciding whether an auxiliary node is needed, and selecting an auxiliary node for the terminal. And there is also a user plane connection between the access network device corresponding to the master node and the core network device. For example, in a 5G network, there is also a user plane connection between the access network device corresponding to the master node and the UPF.

[0133] The access network device corresponding to the auxiliary node (i.e., the second access network device) is used to provide additional wireless resources for the terminal; there may be no direct control plane connection between the access network device corresponding to the auxiliary node and the core network device. However, the access network device corresponding to the auxiliary node can communicate with the core network device through the primary node. A user plane connection can be established between the access network device corresponding to the auxiliary node and the core network device.

[0134] In some embodiments, the second access network device may be various types of base stations. For example, the second access network device may be an eNB, a base station in a 6G communication system, etc.

[0135] In some embodiments, the core network device may be a network function (NF) in the core network. Exemplarily, the core network device may be an AMF, a UPF, or an SMF.

[0136] It should be noted that in the field of wireless communication technology, the wireless interface protocol stack can be divided into two planes, namely the control plane and the user plane. The user plane is responsible for user data processing, while the control plane is responsible for connection establishment, mobility management, security and other control management.

[0137] In some embodiments, the second value of the first parameter is carried in TSCAI. It should be noted that TSCAI can be understood as scheduling auxiliary information of the TSC service.

[0138] In some embodiments, the second value of the first parameter is carried in the control information. In one example, the control information may be NG AP control information. It should be noted that after the core network device completes the configuration of the first parameter, the parameter value of the configured first parameter may be sent to the first access network device through the control plane so that the first access network device performs corresponding processing based on the first parameter.

[0139] In some embodiments, the first parameter is related to a time-sensitive communication service. In one example, the first parameter is associated with an XR service.

[0140] In some embodiments, the first parameter is used to determine arrival information of the data. In one example, the first parameter is used to determine arrival time of the data.

[0141] In some embodiments, the first parameter is used to determine the DRX parameter of the terminal. In one example, the first parameter is used by the first access network device and the second access network device to determine the DRX parameter of the terminal. In one embodiment, the first access network device and / or the second access network device can determine the arrival information of the data packet based on the first parameter, thereby configuring the DRX parameter of the terminal to better achieve energy saving of the terminal.

[0142] In some embodiments, the first parameter may include at least one of the following: a second parameter, used to indicate the time interval between two adjacent data bursts; a third parameter, used to indicate jitter information, which is related to the period of downlink data; a fourth parameter, used to indicate the arrival time of the data burst; and a fifth parameter, used to indicate the time interval to the arrival of the next data burst.

[0143] In some embodiments, the second parameter is used to indicate the time interval between the start times of two adjacent data bursts. In one example, the second parameter may be a period (Periodicity).

[0144] In some embodiments, the third parameter is used to indicate jitter information. In one embodiment, the jitter information is related to the arrival time of the downlink data. In one example, the jitter information may indicate the time difference between the actual arrival time and the expected arrival time of the downlink data.

[0145] In some embodiments, the fourth parameter is used to indicate at least one of the following: the arrival time of the uplink data burst, the arrival time of the downlink data burst. In one embodiment, the arrival time of the uplink data burst refers to the time when the data burst arrives at the exit of the terminal. In one embodiment, the arrival time of the downlink data burst refers to the time when the data burst arrives at the entrance of the access network device. In one example, the fourth parameter can be the burst arrival time (Burst Arrival Time).

[0146] In some embodiments, the fifth parameter is used to indicate the time interval from the arrival time of the next data burst. In one example, the fifth parameter may be the next burst time (Time To Next Burst).

[0147] It should be noted that the above is only an example of the first parameter, and the first parameter may also include other parameters, which is not specifically limited in the embodiments of the present disclosure.

[0148] Step S2102: The core network device sends a first value of a first parameter to a first access network device via a user.

[0149] In some embodiments, the first access network device receives the first value of the first parameter through a user plane.

[0150] In some embodiments, taking into account that the parameter value of the first parameter may change, in order to dynamically indicate the change of the first parameter, the core network device sends the first value of the first parameter to the first access network device through the user plane. In this way, the transmission of the first value of the first parameter is completed during the user plane communication between the core network device and the first access network device, thereby reducing signaling overhead.

[0151] In some embodiments, since the second value of the first parameter is obtained through the control plane, and the first value of the first parameter is obtained through the user plane, it can be seen that the path for the first access network device to obtain the first value of the first parameter is different from the path for obtaining the second value of the first parameter. In some embodiments, the first value of the first parameter is obtained by the first access network device based on the user plane path between itself and the core network device, and the second value of the first parameter is obtained by the first access network device based on the control plane path between itself and the core network device.

[0152] In some embodiments, the first value of the first parameter is carried in a header of a first data packet; the first data packet is a data packet sent by the core network device to the first access network device. For example, the core network device carries the first value of the first parameter in a header of a GTP-U data packet to transmit to the first access network device.

[0153] It is understandable that the core network device may carry the first value in the header of the first data packet, and the core network device may send the first value of the first parameter to the first access network device by sending the first data packet to the first access network device. In this way, the transmission of the first value of the first parameter is completed while the transmission of the first data packet is completed.

[0154] In some embodiments, the first value and the second value may be different. In some embodiments, the first value and the second value may be the same.

[0155] In some embodiments, step S2101 may be omitted. In this case, the core network device only indicates the value of the first parameter to the first access network device through the user.

[0156] In some embodiments, the first value of the first parameter may be carried in a Packet Data Unit (PDU) set information frame. Exemplarily, the first value of the first parameter may be carried in a downlink PDU set information frame.

[0157] In some embodiments, a PDU Set may include one or more PDUs. In some embodiments, all PDUs in a PDU Set are transmitted in the same Quality of Service (QoS) flow.

[0158] In some embodiments, the UPF sends a PDU set information frame to the first access network device, the PDU set information frame including a first value of the first parameter. For example, the UPF may send a PDU set information frame carrying the first value of the first parameter to the NG-RAN node.

[0159] In some embodiments, the first access network device may be composed of a CU and a DU, that is, a RAN separation architecture is adopted.

[0160] In some embodiments, the first value of the first parameter can be sent by the UPF to the CU of the first access network device via a PDU set information frame, and then the CU of the first access network device sends the PDU set information frame carrying the first value of the first parameter to the DU of the first access network device.

[0161] In some embodiments, the first value of the first parameter is used for uplink data transmission and / or downlink data transmission.

[0162] In some embodiments, the first value of the first parameter may be at least one of per terminal, per quality of service flow identifier (Quality of Service flow Identifier, QFI), and per PDU set.

[0163] In some embodiments, the first value of the first parameter is per terminal, which can be understood as the first value of the first parameter is configured according to the terminal; different terminals are configured with different first values ​​of the first parameter.

[0164] In some embodiments, a QFI is associated with a quality of service flow, and the QFI is used to uniquely identify the quality of service flow.

[0165] In some embodiments, the first value of the first parameter is per QFI, which can be understood as the first value of the first parameter is configured according to the QoS flow, and the first value of the first parameter of different QoS flow configurations is different.

[0166] In some embodiments, the first value of the first parameter is per PDU set, which can be understood as the first value of the first parameter is configured according to the PDU set, and the first values ​​of the first parameter configured in different PDU sets are different.

[0167] In some embodiments, the core network device sends third information to the first access network device, where the third information is used to indicate whether the first parameter exists in the first data packet.

[0168] In some embodiments, the third information may be carried in the control information. In one example, the control information may be NGAP control information.

[0169] In some embodiments, the first access network device receives third information sent by the core network device, and determines whether to read the first parameter from the first data packet based on the third information.

[0170] In some embodiments, when the third information indicates that the first parameter exists in the first data packet, the first access network device reads the first value of the first parameter from the first data packet; when the third information indicates that the first parameter does not exist in the first data packet, the first access network device does not read the first value of the first parameter.

[0171] In some embodiments, different values ​​of the third information may be used to indicate whether the first parameter exists in the first data packet. In one example, the third information has a first value, indicating that the first value of the first parameter exists; or the third information has a second value, indicating that the first value of the first parameter does not exist.

[0172] In some embodiments, whether the core network device sends the third information can be used to indicate whether the first parameter exists in the first data packet. In one example, when the first access network device receives the third information sent by the core network device, it is determined that the first parameter exists in the first data packet, and the first access network device reads the first value of the first parameter from the first data packet; when the first access network device does not receive the third information sent by the core network device, it is determined that the first parameter does not exist in the first data packet, and the first access network device does not read the first value of the first parameter.

[0173] In some embodiments, the first access network device may also receive a sixth parameter sent by the core network device through the control plane, where the sixth parameter is different from the first parameter.

[0174] In some embodiments, the sixth parameter may include at least one of the following: a second parameter, used to indicate the time interval between two adjacent data bursts; a third parameter, used to indicate jitter information, which is related to the period of downlink data; a fourth parameter, used to indicate the arrival time of the data burst; and a fifth parameter, used to indicate the time interval to the arrival of the next data burst.

[0175] In one example, the first access network device receives the period and jitter information sent by the core network device through the control plane; the first access network device receives the period sent by the core network device through the user plane. It can be understood that, with respect to the period, the first access network device obtains the second value and the first value of the period through the control plane and the user plane respectively, and the first access network device needs to determine whether to use the second value of the period or the first value of the period.

[0176] Step S2103: The first access network device determines the arrival information of the data according to the first parameter.

[0177] In some embodiments, the first parameter is used to determine the arrival information of the data. For example, the first parameter is used to determine the arrival time of the data.

[0178] In some embodiments, after the first access network device obtains the value of the first parameter through the above steps S2101 and S2102, it can perform corresponding processing based on the value of the first parameter to determine the arrival information of the data. However, since the first access network device obtains two parameter values ​​(such as the first value and the second value) of the first parameter from the core network device through the user plane and the control plane respectively, at this time, the first access network device needs to determine whether to use the first value or the second value. In one embodiment, the first access network device can determine the arrival information of the data based on the determined parameter value of the first parameter (such as the first value).

[0179] In some embodiments, the first access network device may determine the parameter value of the first parameter in the following manner, but is not limited to the following manner.

[0180] In method 1, the first access network device may preferentially use the first value as the parameter value of the first parameter. In some embodiments, the first value is sent to the first access network device by the core network device through the user plane, and the core network device can timely inform the first access network device in this dynamic manner according to the change of data transmission. Therefore, compared with the second value, the first access network device can more accurately determine the arrival information of the data by using the first value.

[0181] In some embodiments, the first access network device preferentially uses the first value, including: preferentially using the fifth parameter having the first value in the first parameter. In some embodiments, the fifth parameter is used to indicate the time interval from the arrival of the next data burst. Then, when the first access network device obtains the fifth parameter having the first value from the core network device through the user plane, the first access network device can directly and accurately determine the arrival time of the next data burst according to the time interval indicated by the fifth parameter.

[0182] In some embodiments, when the first access network device obtains a fifth parameter with a first value through a user plane and the first access network device obtains a second parameter with a second value through a control plane, the first access network device preferentially uses the fifth parameter with the first value. In some embodiments, the fifth parameter with the first value and the second parameter with the second value are different types of first parameters obtained by the first access network device through different paths. Although the parameter types are different, both the second parameter and the fifth parameter can be used to determine the arrival time of the next data burst. Compared with the second parameter with the second value, the fifth parameter with the first value obtained by the first access network device in a dynamic manner can more accurately determine the arrival time. In this case, the first access network device preferentially uses the fifth parameter with the first value.

[0183] In some embodiments, when the first access network device obtains a second parameter having a first value and a fifth parameter having a first value through a user plane, the first access network device gives priority to using the fifth parameter having the first value. In some embodiments, the second parameter is used to indicate the time interval between two adjacent data bursts, and the arrival time of the next data burst can be determined based on the second parameter. The fifth parameter is used to indicate the time interval from the arrival of the next data burst, and the arrival time of the next data burst can also be determined based on the fifth parameter. Since the first access network device does not need to obtain information such as the start time and end time of the previous data burst when using the fifth parameter having the first value to determine the arrival time of the next data burst. In this case, the first access network device can give priority to using the fifth parameter having the first value. In this way, not only can the arrival information of the data be determined more accurately, but also the processing efficiency can be improved.

[0184] In the second method, the first access network device may replace the parameter value of the first parameter from the second value to the first value. In some embodiments, when the first parameter obtained by the first access device through the user plane and the first parameter obtained through the control plane are the same parameter, the first access network device may replace the second value of the first parameter with the first value of the first parameter. In one example, the first access network device uses the first parameter obtained from the core network device through the user plane to replace the first parameter obtained by the first access network device from the core network device through the control plane.

[0185] Step S2104: the first access network device sends a first value of a first parameter to the second access network device.

[0186] In some embodiments, the second access network device receives the first value sent by the first access network device.

[0187] In some embodiments, before the first access network device sends the first value to the second access network device, the second access network device has obtained the second value of the first parameter pre-configured by the core network device through the control plane. When the path conversion of the user plane path is completed, the second access network device can use the second value of the first parameter to perform corresponding processing.

[0188] In some embodiments, if the core network device reconfigures the first parameter before the path conversion of the user plane path, that is, the parameter value of the first parameter is updated, at this time, the core network device can indicate the change of the parameter value of the first parameter to the first access network device by sending a first data packet carrying the first value of the first parameter to the first access network device.

[0189] In some embodiments, the first access network device may not forward the first value of the first parameter to the second access network device. For example, when the first access network device has sent the first data packet carrying the first value of the first parameter sent by the core network device to the terminal, the first value of the first parameter will not be forwarded to the second access network device. In this case, the second access network device cannot obtain the updated parameter value of the first parameter, so that after the path conversion of the user plane path is completed, the second access network device, the first access network device and the core network device do not reach a consistent understanding of the parameter value of the first parameter. At this time, the second access network device still uses the second value for corresponding processing, thereby affecting the communication of the terminal. Then, in order to reduce the occurrence of the above situation, after obtaining the first value of the first parameter, the first access network device can send the first value to the second access network device, so that the second access network device can obtain the updated parameter value of the first parameter in time, so that after the path conversion of the user plane path is completed, the second access network device, the first access network device and the core network device can reach a consistent understanding of the parameter value of the first parameter.

[0190] In some embodiments, the first access network device sends the first value to the second access network device through a user interface.

[0191] In some embodiments, the first value of the first parameter may be carried in a header of a second data packet, and the second data packet is a data packet sent by the first access network device to the second access network device. In one example, the first access network device carries the first value of the first parameter in a GTP-U header and transmits it to the second access network device.

[0192] In some embodiments, the second data packet and the first data packet may be the same data packet. In one example, after receiving the first data packet, the first access network device forwards the first data packet to the second access network device. In one example, the second data packet and the first data packet may be different data packets. In one example, after receiving the first data packet, the first access network device obtains the first value of the first parameter from the header of the first data packet, carries the first value of the first parameter in the header of the second data packet, and sends it to the second access network device.

[0193] In some embodiments, the first value of the first parameter may be carried in a PDU set information frame. Exemplarily, the first value of the first parameter may be carried in a downlink PDU set information frame.

[0194] In some embodiments, the first access network device may send a downlink PDU set information frame to the second access network device, where the downlink PDU set information frame includes a first value of the first parameter.

[0195] In some embodiments, the first access network device sends the first value of the first parameter to the second access network device through a control plane.

[0196] In some embodiments, the first value of the first parameter is carried in first control information, and the first control information is control information sent by the first access network device to the second access network device.

[0197] In some embodiments, the first control information may be Xn Application Protocol (AP) signaling.

[0198] In some embodiments, the first access network device sending the first value of the first parameter to the second access network device may include at least one of the following situations:

[0199] In case 1, when the terminal switches from a source cell to a target cell, the first access network device sends a first value to the second access network device, the first access network device is related to the source cell, and the second access network device is related to the target cell;

[0200] Case 2: when the terminal adds the first secondary node, the first access network device sends the first value to the second access network device, and the first access network device is related to the first secondary node;

[0201] Case three, when the terminal modifies the second secondary node, the first access network device sends the first value to the second access network device, and the first access network device is related to the second secondary node.

[0202] In some embodiments, in scenarios such as cell switching, secondary node addition, and secondary node modification, the first access network device sends the acquired first value of the first parameter to the second access network device. For example, in a cell switching scenario, the first access network device may send a downlink PDU set information frame to the second access network device, and the downlink PDU set information frame includes the first value of the first parameter. Alternatively, in a terminal dual connection scenario, the first access network device may send a downlink PDU set information frame to the second access network device, and the downlink PDU set information frame includes the first value of the first parameter.

[0203] In some embodiments, the first value of the first parameter is used by the second access network device to determine arrival information of the data.

[0204] In some embodiments, after receiving the first value of the first parameter sent by the first access network device, the second access network device may use the first value of the first parameter to determine the arrival information of the data.

[0205] In some embodiments, the first value of the first parameter is used by the second access network device to determine a DRX parameter of the terminal.

[0206] In some embodiments, the second access network device determines the arrival information of the data according to the first value of the first parameter, thereby configuring the DRX parameters of the terminal based on the arrival information of the data to achieve terminal energy saving.

[0207] In some embodiments, the term "information" can be interchangeably with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0208] In some embodiments, the term "send" can be interchangeable with terms such as "transmit", "report", and "transmit".

[0209] The communication method involved in the embodiment of the present disclosure may include at least one of step S2101 to step S2104. For example, step S2101 combined with step S2103 may be implemented as an independent embodiment, and step S2101 to step S2103 may be implemented as an independent embodiment, but are not limited thereto.

[0210] In some embodiments, step S2102 and step S2104 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that, in the case where the core network device does not send the first value to the first access network device through the user, the first access network device may determine the arrival information of the data based on the second value.

[0211] In some embodiments, step S2104 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that the second access network device may obtain the first value from the core network device without the first access network device sending the first value to the second access network device.

[0212] Figure 2B FIG. 2 is a second interactive diagram of a communication method according to an exemplary embodiment. Figure 2B As shown, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100, and the method includes:

[0213] Step S2201: The core network device sends the second value of the first parameter to the first access network device through a control plane.

[0214] In some embodiments, other optional implementations of step S2201 can be found in Figure 2AOptional implementations of step S2101, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0215] Step S2202: The core network device sends a first value of a first parameter to a first access network device via a user.

[0216] In some embodiments, other optional implementations of step S2202 can be found in Figure 2A Optional implementations of step S2102, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0217] Step S2203: The first access network device determines the arrival information of the data according to the first parameter.

[0218] In some embodiments, other optional implementations of step S2203 can be found in Figure 2A Optional implementations of step S2103, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0219] Step S2204: The second access network device sends information to the core network device.

[0220] In some embodiments, the core network device receives information sent by the second access network device.

[0221] In some embodiments, the second access network device sends first information to the core network device, where the first information is used to indicate a path conversion request.

[0222] In some embodiments, path conversion may occur during the communication process, for example, the terminal switches from the source cell to the target cell. In this case, the second access network device sends the first information to the core network device to request the core network device to change the path of the user plane data of the terminal.

[0223] In some embodiments, in the case of path conversion on the user plane, the second access network device will generally use the second value of the first parameter obtained in advance from the core network device through the control plane to perform corresponding processing.

[0224] In some embodiments, if the core network device reconfigures the first parameter before the path conversion of the user plane path, that is, the parameter value of the first parameter is updated. At this time, the second access network device may not be able to know the parameter value of the updated first parameter, so that after the conversion of the user plane path is completed, the second access network device, the first access network device and the core network device do not reach a consistent understanding of the parameter value of the first parameter. At this time, the second access network device still uses the second value for corresponding processing, thereby affecting the communication of the terminal. Then, in order to reduce the occurrence of the above situation, the second access network device sends the first information to the core network device to inform the core network device when the user plane path is converted, so that the core network device can actively send the first value to the second access network device, so that the second access network device can obtain the updated parameter value of the first parameter in time. In this way, after the path conversion of the user plane path is completed, the second access network device, the first access network device and the core network device can reach a consistent understanding of the parameter value of the first parameter.

[0225] In some embodiments, the second access network device sends second information to the core network device, where the second information is used to request the first parameter.

[0226] In some embodiments, since the parameter value of the first parameter may be updated, the second access network device may send a second message to the core network device to request the core network device to send the first parameter to the second access network device; thereby, the second access network device can obtain the updated parameter value of the first parameter in a timely manner, and can more accurately determine the arrival information of the data based on the received first parameter.

[0227] In some embodiments, the second information is sent by the second access network device after the path conversion is completed.

[0228] In some embodiments, in order to reduce some unnecessary information interactions, the second access network device may send the second information to the core network device after the path conversion is completed to request the first parameter. It is understandable that before the path conversion is completed, since the transmission of the user plane data of the terminal is the responsibility of the first access network device, even if the second access network device, the first access network device and the core network device do not reach a consensus on the parameter value of the first parameter, it will not affect the terminal's reception of data. Therefore, in this case, the second access network device may not send the second information to the core network device.

[0229] Step S2205: The core network device sends the first value of the first parameter to the second access network device through the user.

[0230] In some embodiments, the second access network device obtains the first value of the first parameter sent by the core network device through the user plane.

[0231] In some embodiments, the first value is carried in a header of a third data packet, and the third data packet is a data packet sent by the core network device to the second access network device. For example, the core network device carries the first value in a GTP-U header to transmit it to the second access network device.

[0232] It should be noted that before the core network device sends the first value of the first parameter to the second access network device, the second access network device has obtained the second value of the first parameter pre-configured by the core network device through the control plane. When the path conversion of the user plane path is completed, the second access network device can use the second value of the first parameter for corresponding processing.

[0233] In some embodiments, if the core network device reconfigures the first parameter before the path conversion of the user plane path, that is, the parameter value of the first parameter is updated, at this time, the core network device can indicate the change of the parameter value of the first parameter to the first access network device by sending a first data packet carrying the first value of the first parameter to the first access network device.

[0234] In some embodiments, the first access network device will not forward the first value of the first parameter to the second access network device. For example, when the first access network device has sent the first data packet carrying the first value of the first parameter sent by the core network device to the terminal, the first value of the first parameter will not be forwarded to the second access network device. In this case, the second access network device cannot obtain the updated parameter value of the first parameter, so that after the path conversion of the user plane path is completed, the second access network device, the first access network device and the core network device do not reach a consensus on the parameter value of the first parameter. At this time, the second access network device still uses the second value for corresponding processing, thereby affecting the communication of the terminal.

[0235] In order to reduce the occurrence of the above situation, the second access network device can directly obtain the updated parameter value of the first parameter from the core network device; thus, after the path conversion of the user plane path is completed, the second access network device, the first access network device and the core network device can reach a consistent understanding of the parameter value of the first parameter.

[0236] In some embodiments, the core network device sending the first value of the first parameter to the second access network device may include at least one of the following situations:

[0237] Case 1: When the core network device receives the first information sent by the second access network device, the core network device sends the first value to the second access network device according to the first information;

[0238] In the second case, when the core network device receives the second information sent by the second access network device, the core network device sends the first value to the second access network device according to the second information.

[0239] In some embodiments, the first information is information sent by the second access network device to the core network device, and the first information is used to indicate a path conversion request. When the core network device receives the first information, the core network device can actively send the first value to the second access network device, so that the second access network device can obtain the updated parameter value of the first parameter in time, so that after the path conversion of the user plane path is completed, the second access network device, the first access network device and the core network device can reach a consistent understanding of the parameter value of the first parameter.

[0240] In some embodiments, the second information is information sent by the second access network device to the core network device, and the second information is used to request the first parameter. In some embodiments, the second information is sent by the second access network device after the path conversion is completed.

[0241] In some embodiments, the second access network device may actively send the second information to the core network device to request the first parameter. After receiving the second information, the core network device sends the updated parameter value of the first parameter to the second access network device, so that the second access network device can obtain the updated parameter value of the first parameter in time, so that after the path conversion of the user plane path is completed, the second access network device, the first access network device and the core network device can reach a consistent understanding of the parameter value of the first parameter.

[0242] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2201 to S2205. For example, step S2201 combined with step S2203 may be implemented as an independent embodiment, and steps S2201 to S2203 may be implemented as independent embodiments, but are not limited thereto.

[0243] In some embodiments, step S2202, step S2204, and step S2205 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that, in the case where the core network device does not send the first value to the first access network device through the user, the first access network device may determine the arrival information of the data based on the second value.

[0244] In some embodiments, step S2204 and step S2205 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that the second access network device may obtain the first value from the first access network device without the second access network device sending information to the core network device, and without the core network device sending the first value to the second access network device.

[0245] Figure 2C FIG. 3 is an interactive schematic diagram of a communication method according to an exemplary embodiment. Figure 2CAs shown, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100. The communication method may include:

[0246] Step S2301: The core network device sends the second value of the first parameter through the control plane.

[0247] In some embodiments, the core network device sends the second value of the first parameter to the access network device through a control plane.

[0248] In some embodiments, the access network device receives the second value of the first parameter through the control plane.

[0249] In some embodiments, the access network device may be an access network device corresponding to a current serving cell of the terminal. Exemplarily, the access network device may be an access network device.

[0250] In some embodiments, the access network device may be various types of base stations. For example, the access network device may be an eNB, a base station in a 6G communication system, etc.

[0251] In some embodiments, the core network device may be a NF in the core network. Exemplarily, the core network device may be an AMF, a UPF, or an SMF, etc.

[0252] It should be noted that in the field of wireless communication technology, the wireless interface protocol stack can be divided into two planes, namely the control plane and the user plane. The user plane is responsible for user data processing, while the control plane is responsible for connection establishment, mobility management, security and other control management.

[0253] In some embodiments, the second value of the first parameter is carried in TSCAI. It should be noted that TSCAI can be understood as scheduling auxiliary information of the TSC service.

[0254] In some embodiments, the second value of the first parameter is carried in the control information. In one example, the control information may be NG AP control information. It should be noted that after the core network device completes the configuration of the first parameter, the parameter value of the configured first parameter may be sent to the access network device through the control plane so that the access network device performs corresponding processing based on the first parameter.

[0255] In some embodiments, the first parameter is related to a time-sensitive communication service. In one example, the first parameter is associated with an XR service.

[0256] In some embodiments, the first parameter is used to determine arrival information of the data. In one example, the first parameter is used to determine arrival time of the data.

[0257] In some embodiments, the first parameter is used to determine the DRX parameter of the terminal. In one example, the first parameter is used by the access network device to determine the DRX parameter of the terminal. In one embodiment, the access network device can determine the arrival information of the data packet based on the first parameter, thereby configuring the DRX parameter of the terminal to better achieve energy saving of the terminal.

[0258] In some embodiments, the first parameter may include at least one of the following: a second parameter, used to indicate the time interval between two adjacent data bursts; a third parameter, used to indicate jitter information, which is related to the period of downlink data; a fourth parameter, used to indicate the arrival time of the data burst; and a fifth parameter, used to indicate the time interval to the arrival of the next data burst.

[0259] In some embodiments, the second parameter is used to indicate the time interval between the start times of two adjacent data bursts. In one example, the second parameter may be a period (Periodicity).

[0260] In some embodiments, the third parameter is used to indicate jitter information. In one embodiment, the jitter information is related to the arrival time of the downlink data. In one example, the jitter information may indicate the time difference between the actual arrival time and the expected arrival time of the downlink data.

[0261] In some embodiments, the fourth parameter is used to indicate at least one of the following: the arrival time of the uplink data burst, the arrival time of the downlink data burst. In one embodiment, the arrival time of the uplink data burst refers to the time when the data burst arrives at the exit of the terminal. In one embodiment, the arrival time of the downlink data burst refers to the time when the data burst arrives at the entrance of the access network device. In one example, the fourth parameter can be the burst arrival time (Burst Arrival Time).

[0262] In some embodiments, the fifth parameter is used to indicate the time interval from the arrival time of the next data burst. In one example, the fifth parameter may be the next burst time (Time To Next Burst).

[0263] It should be noted that the above is only an example of the first parameter, and the first parameter may also include other parameters, which is not specifically limited in the embodiments of the present disclosure.

[0264] Step S2302: The core network device sends a first value of a first parameter to the access network device through a user.

[0265] In some embodiments, the access network device receives the first value of the first parameter through a user plane.

[0266] In some embodiments, taking into account that the parameter value of the first parameter may change, in order to dynamically indicate the change of the first parameter, the core network device sends the first value of the first parameter to the access network device through the user plane. In this way, the transmission of the first value of the first parameter is completed during the user plane communication between the core network device and the access network device, thereby reducing signaling overhead.

[0267] In some embodiments, since the second value of the first parameter is obtained through the control plane, and the first value of the first parameter is obtained through the user plane, it can be seen that the path for the access network device to obtain the first value of the first parameter is different from the path for obtaining the second value of the first parameter. In some embodiments, the first value of the first parameter is obtained by the access network device based on the user plane path between itself and the core network device, and the second value of the first parameter is obtained by the access network device based on the control plane path between itself and the core network device.

[0268] In some embodiments, the first value of the first parameter is carried in a header of a first data packet; the first data packet is a data packet sent by a core network device to an access network device. For example, the core network device carries the first value of the first parameter in a header of a GTP-U data packet to transmit to the access network device.

[0269] It is understandable that the core network device may carry the first value in the header of the first data packet, and the core network device may send the first value of the first parameter to the access network device by sending the first data packet to the access network device. In this way, the transmission of the first value of the first parameter is completed while the transmission of the first data packet is completed.

[0270] In some embodiments, the first value and the second value may be different. In some embodiments, the first value and the second value may be the same.

[0271] In some embodiments, step S2101 may be omitted. In this case, the core network device only indicates the value of the first parameter to the access network device through the user.

[0272] In some embodiments, the first value of the first parameter may be carried in a PDU set information frame. Exemplarily, the first value of the first parameter may be carried in a downlink PDU set information frame.

[0273] In some embodiments, a PDU set may include one or more PDUs. In some embodiments, all PDUs in a PDU set are transmitted in the same QoS flow.

[0274] In some embodiments, the UPF sends a PDU set information frame to the access network device, the PDU set information frame including a first value of the first parameter. For example, the UPF may send a PDU set information frame carrying the first value of the first parameter to the NG-RAN node.

[0275] In some embodiments, the access network equipment may be composed of a CU and a DU, that is, a RAN separation architecture is adopted.

[0276] In some embodiments, the first value of the first parameter can be sent by the UPF to the CU of the access network device via a PDU set information frame; and then the CU of the access network device sends the PDU set information frame carrying the first value of the first parameter to the DU of the access network device.

[0277] In some embodiments, the first value of the first parameter is used for uplink data transmission and / or downlink data transmission.

[0278] In some embodiments, the type of the first value of the first parameter may be at least one of a terminal granularity type, a quality of service flow granularity type, and a PDU set granularity type.

[0279] In some embodiments, the first value of the first parameter may be at least one of per terminal, per quality of service flow identifier (Quality of Service flow Identifier, QFI), and per PDU set.

[0280] In some embodiments, the first value of the first parameter is per terminal, which can be understood as the first value of the first parameter is configured according to the terminal; different terminals are configured with different first values ​​of the first parameter.

[0281] In some embodiments, a QFI is associated with a quality of service flow, and the QFI is used to uniquely identify the quality of service flow.

[0282] In some embodiments, the first value of the first parameter is per QFI, which can be understood as the first value of the first parameter is configured according to the QoS flow, and the first value of the first parameter of different QoS flow configurations is different.

[0283] In some embodiments, the first value of the first parameter is per PDU set, which can be understood as the first value of the first parameter is configured according to the PDU set, and the first values ​​of the first parameter configured in different PDU sets are different.

[0284] In some embodiments, the core network device sends third information to the access network device, where the third information is used to indicate whether the first parameter exists in the first data packet.

[0285] In some embodiments, the third information may be carried in the control information. In one example, the control information may be NGAP control information.

[0286] In some embodiments, the access network device receives third information sent by the core network device, and determines whether to read the first parameter from the first data packet based on the third information.

[0287] In some embodiments, when the third information indicates that the first parameter exists in the first data packet, the access network device reads the first value of the first parameter from the first data packet; when the third information indicates that the first parameter does not exist in the first data packet, the access network device does not read the first value of the first parameter.

[0288] In some embodiments, different values ​​of the third information may be used to indicate whether the first parameter exists in the first data packet. In one example, the third information has a first value, indicating that the first value of the first parameter exists; or the third information has a second value, indicating that the first value of the first parameter does not exist.

[0289] In some embodiments, whether the core network device sends the third information can be used to indicate whether the first parameter exists in the first data packet. In one example, when the access network device receives the third information sent by the core network device, it is determined that the first parameter exists in the first data packet, and the access network device reads the first value of the first parameter from the first data packet; when the access network device does not receive the third information sent by the core network device, it is determined that the first parameter does not exist in the first data packet, and the access network device does not read the first value of the first parameter.

[0290] In some embodiments, the number of first parameters sent by the core network device to the access network device via the control plane may be different from the number of first parameters sent by the core network device to the access network device via the user plane.

[0291] Exemplarily, the core network device may send the second value of the first parameter to the access network device through the control plane, wherein the first parameter sent through the control plane may include: the second parameter, the third parameter and the fourth parameter. The core network device may send the first value of the first parameter to the access network device through the user plane, wherein the first parameter sent through the user plane may include: the second parameter. Thus, the access network device obtains the first value and the second value of the second parameter through the control plane and the user plane respectively; and the access network device also obtains the second value of the third parameter and the second value of the fourth parameter through the control plane. For the second parameter, the access network device needs to determine whether to use the first value or the second value.

[0292] Step S2303: The access network device determines the arrival information of the data according to the first parameter.

[0293] In some embodiments, the first parameter is used to determine the arrival information of the data. For example, the first parameter is used to determine the arrival time of the data.

[0294] In some embodiments, after obtaining the value of the first parameter through the above steps S2101 and S2102, the access network device can perform corresponding processing based on the value of the first parameter to determine the arrival information of the data. However, since the access network device obtains two parameter values ​​(such as the first value and the second value) of the first parameter from the core network device through the user plane and the control plane respectively, at this time, the access network device needs to determine whether to use the first value or the second value. In one embodiment, the access network device can determine the arrival information of the data based on the determined parameter value of the first parameter (such as the first value).

[0295] In some embodiments, the access network device may determine the parameter value of the first parameter in the following manner, but is not limited to the following manner.

[0296] In method 1, the access network device may preferentially use the first value as the parameter value of the first parameter. In some embodiments, the first value is sent to the access network device by the core network device through the user plane, and the core network device can timely inform the access network device in this dynamic manner according to the change of data transmission. Therefore, compared with the second value, the access network device can more accurately determine the arrival information of the data by using the first value.

[0297] In some embodiments, the access network device preferentially uses the first value, including: preferentially using the fifth parameter having the first value in the first parameter. In some embodiments, the fifth parameter is used to indicate the time interval from the arrival of the next data burst. Then, when the access network device obtains the fifth parameter having the first value from the core network device through the user plane, the access network device can directly and accurately determine the arrival time of the next data burst according to the time interval indicated by the fifth parameter.

[0298] In some embodiments, when the access network device obtains a fifth parameter with a first value through a user plane and the access network device obtains a second parameter with a second value through a control plane, the access network device preferentially uses the fifth parameter with the first value. In some embodiments, the fifth parameter with the first value and the second parameter with the second value are different types of first parameters obtained by the access network device through different paths. Although the parameter types are different, both the second parameter and the fifth parameter can be used to determine the arrival time of the next data burst. Compared with the second parameter with the second value, the fifth parameter with the first value obtained by the access network device in a dynamic manner can more accurately determine the arrival time. In this case, the access network device preferentially uses the fifth parameter with the first value.

[0299] In some embodiments, when the access network device obtains a second parameter having a first value and a fifth parameter having a first value through a user plane, the access network device gives priority to using the fifth parameter having the first value. In some embodiments, the second parameter is used to indicate the time interval between two adjacent data bursts, and the arrival time of the next data burst can be determined based on the second parameter. The fifth parameter is used to indicate the time interval from the arrival of the next data burst, and the arrival time of the next data burst can also be determined based on the fifth parameter. Since the access network device does not need to obtain information such as the start time and end time of the previous data burst when using the fifth parameter having the first value to determine the arrival time of the next data burst. In this case, the access network device can give priority to using the fifth parameter having the first value. In this way, not only can the arrival information of the data be determined more accurately, but also the processing efficiency can be improved.

[0300] In the second method, the access network device may replace the parameter value of the first parameter from the second value to the first value. In some embodiments, when the first parameter obtained by the first access device through the user plane and the first parameter obtained through the control plane are the same parameter, the access network device may replace the second value of the first parameter with the first value of the first parameter. In one example, the access network device uses the first parameter obtained from the core network device through the user plane to replace the first parameter obtained by the access network device from the core network device through the control plane.

[0301] In some embodiments, the term "information" can be interchangeably with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

[0302] In some embodiments, the term "send" can be interchangeable with terms such as "transmit", "report", and "transmit".

[0303] The communication method involved in the embodiment of the present disclosure may include at least one of step S2301 to step S2303. For example, step S2301 combined with step S2303 may be implemented as an independent embodiment, and step S2302 to step S2303 may be implemented as an independent embodiment, but are not limited thereto.

[0304] In some embodiments, step S2302 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that, in the case where the core network device does not send the first value to the access network device via the user, the access network device may determine the arrival information of the data based on the second value.

[0305] In some embodiments, step S2301 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that the core network device may indicate the value of the first parameter to the access network device only through the user.

[0306] Figure 3A A communication method according to an exemplary embodiment is shown in FIG. Figure 1 .like Figure 3A As shown, the embodiment of the present disclosure relates to a communication method, which is performed by a first access network device 1021, and the method includes:

[0394] In some embodiments, the first information is obtained from a user plane / data plane message sent by the core network. As an example, the first information is obtained from a GTP-U packet header.

[0395] In some embodiments, the first information is included in a downlink PDU set information frame (DL PDU Set Information frame).

[0396] In some embodiments, the first information is sent by the UPF to the NG-RAN node via a DL PDU Set Information frame.

[0397] In some embodiments, the first information is sent by the first NG-RAN node to the second NG-RAN node via a DL PDU Set Information frame (handover process or DC scenario);

[0398] In some embodiments, the first information is sent by the UPF to the gNB-CU via a DL PDU Set Information frame, and then sent by the gNB-CU to the gNB-DU (RAN split scenario, i.e., split architecture);

[0399] In some embodiments, the first information is sent from the gNB-CU to the gNB-DU via a DL PDU Set Information frame (RAN split scenario, i.e., separate architecture);

[0400] In some embodiments, after the base station obtains the first information from the core network, it uses it according to the agreed rules of the protocol.

[0401] In some embodiments, the first information will take precedence over or replace the use of the second information.

[0402] In some embodiments, the second information is obtained from NG AP control information sent by the core network.

[0403] In some embodiments, the period obtained from the GTP-U header will take precedence or replace the period obtained from the NG AP control information.

[0404] In some embodiments, the time interval for the arrival of the next data packet obtained from the GTP-U header will take precedence or replace the period obtained from the NG AP control information and / or the period obtained from the GTP-U header.

[0405] As an embodiment, the first information is at least one of per UE, per QFI, and per PDU set.

[0407] In some embodiments, the first information obtained by the base station from the core network will be transmitted to the second base station; the obtained first information is transmitted to the second base station by being carried in the GTP-U packet header.

[0408] As an example, the first base station can extract the first information from the GTP-U packet header of packet A obtained from the core network. When forwarding data, the first information extracted from the GTP-U packet header of packet A is carried in the GTP-U packet header of packet B and forwarded to the second base station (packet A and packet B may be the same or different).

[0413] In some embodiments, when the second base station notifies the core network that the path conversion is complete, the core network may proactively inform the second base station of the updated first information.

[0414] In some embodiments, after notifying the core network that the path conversion is complete, the second base station may notify the core network and actively request an update of the first information.

[0415] In some embodiments, the base station receives a first indication from the core network, wherein the first indication is used to indicate whether the first information exists.

[0416] In some embodiments, the base station reads the first information according to the first indication.
