Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to an information processing method, apparatus, communication device, and storage medium. Background Technology

[0002] ATSSS (Access Traffic Steering, Switching, Splitting) allows User Equipment (UE) to simultaneously access the 5G core network using both 3GPP (3rd Generation Partnership Project) and non-3GPP access networks, and establish MA PDU (Multi Access Protocol Data Unit) sessions. This enables the same service data stream to simultaneously utilize two access networks for switching, splitting, and backup transmission, improving network resource utilization efficiency and enhancing the service experience. Summary of the Invention

[0003] This disclosure provides an information processing method, apparatus, communication device, and storage medium.

[0004] A first aspect of this disclosure provides an information processing method, wherein the method is executed by a user equipment (UE), and includes:

[0005] In response to receiving a pause data transmission replication message and not configuring a primary access method, a default access method is set; the default access method is one of the multiple access methods currently used by the UE, and the default access method is used for data transmission after the data transmission replication is paused;

[0006] In response to receiving the message to resume data transmission replication, the default access method setting is cancelled.

[0007] A second aspect of this disclosure provides an information processing method, wherein the method is executed by a network device, the method comprising:

[0008] In response to sending a pause data transmission replication message and not configuring a primary access method, a default access method is set; the default access method is one of the multiple access methods currently used by the user equipment (UE), and the default access method is used for data transmission after pausing data transmission replication;

[0009] In response to sending a message to resume data transmission replication, the default access method setting is cancelled.

[0010] A third aspect of this disclosure provides an information processing apparatus, wherein the apparatus includes:

[0011] The first processing module is configured to set a default access method in response to receiving a pause data transmission replication message when no primary access method is configured; the default access method is one of several access methods currently used by the UE; the default access method is used for data transmission after the data transmission replication is paused;

[0012] The second processing module is configured to cancel the default access mode setting in response to receiving a message to resume data transmission replication.

[0013] A fourth aspect of this disclosure provides an information processing apparatus, wherein the apparatus includes:

[0014] The third processing module is configured to set a default access method in response to the fact that no primary access method is configured when a pause data transmission replication message is sent; the default access method is one of the multiple access methods currently used by the UE, and the default access method is used for data transmission after the data transmission replication is paused;

[0015] The fourth processing module is configured to cancel the default access mode setting in response to sending a recovery data transmission replication message.

[0016] A fifth aspect of this disclosure provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and capable of being executed by the processor, wherein when the processor executes the executable program, it performs the information processing method as provided in the first or second aspect described above.

[0018] The technical solution provided in this disclosure, when data transmission replication is paused and no primary access method is configured, allows the UE and network device to use a unified default access method for data transmission during the pause period. This avoids timing issues caused by using different access methods for uplink and downlink data transmission, thus improving data transmission reliability. Furthermore, after resuming data transmission replication, canceling the default access setting restores the access settings of the UE and network device before the data transmission replication pause, reducing communication anomalies caused by differences in access method settings before and after the pause.

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of the present invention.

[0039] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments disclosed herein. The singular forms “a,” “the,” and “the” used herein are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0040] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0041] Please refer to Figure 1A This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1A As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11, one or more access devices 12, and one or more core network devices 13.

[0042] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, UE 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0043] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0044] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0045] Access device 12 and UE 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0046] Core network device 13 can be connected to access device 12. Typical core network devices may include, but are not limited to: Access Management Function (UDM), Session Management Function (SMF), User Data Management (UDM), and Policy Control Function (PCF).

[0047] like Figure 1BAs shown, the UE can access the User Plane Function (UPF) via the N3 interface in either 3GPP or non-3GPP access modes. The UE can also connect to the Access and Mobility Management Function (AMF) via the N1 interface. The UE supports Multipath Transmission Control Protocol (MPTCP), Multipath Quick UDP Internet Connections (MPQUIC), ATSSS-LL (ATSSS Low-Layer), and Performance Measurement Functionality (PMF). The UPF supports MPTCP proxy functionality, MPQUIC functionality, and PMF. Both 3GPP and non-3GPP access network devices connect to the AMF via the N2 interface. The AMF connects to the Session Management Function (SMF) via the N11 interface, and the SMF connects to the Policy Control Function (PCF) via the N7 interface. UPF connects to the data network via N6.

[0048] Redundant steering mode is one of the steering modes that ATSSS should support. Redundant steering mode enables the sending end (UE for uplink transmission or UPF for downlink transmission) to support redundant service steering in a replicated manner to improve the reliability and latency of data transmission.

[0049] Before enabling the redundancy offloading mode, the UE and UPF can be configured with a primary access method or not.

[0050] For example, before enabling the redundancy offloading mode, the network can use ATSSS rules and N4 rules to configure the primary access method for the UE, regardless of whether a threshold is set. If the primary access method is configured, the UE and UPF can transmit service data streams on the primary access path and back up (copy) the transmission on another access path.

[0051] However, before enabling the redundancy splitting mode, for transmissions with a threshold setting, if the network device does not configure a primary access method for the UE, the UE and UPF can set their own primary access methods during data transmission. For transmissions without a threshold setting, if the network device does not configure a primary access method for the UE, the UE and UPF will perform transmission replication for the service data streams transmitted in both access methods (for example, if service data stream 1 is transmitted using access method A, then access method B is used for backup transmission; if service data stream 2 is transmitted using access method B, then access method A is used for backup transmission). If the UPF needs to pause transmission replication, it can send a pause data transmission replication request message to the UE, indicating the data type to be paused. Once the UE receives the message, it needs to pause transmission replication for the indicated data type. During the pause of transmission replication, the UE and UPF use the primary access method for data transmission. However, for transmissions without a threshold setting, if no primary access method is configured, it is unclear how the access method will be used for data transmission between the UE and UPF during the pause of transmission replication.

[0052] like Figure 2A As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE). The method includes:

[0053] S1110: In response to receiving a pause data transmission replication message and not configuring a primary access method, set a default access method; the default access method is one of the multiple access methods currently used by the UE, and the default access method is used for data transmission after the data transmission replication is paused;

[0054] S1120: In response to receiving the resume data transmission replication message, cancel the default access mode setting.

[0055] For example, the multiple access methods currently used by the UE include: 3GPP access methods and non-3GPP access methods.

[0056] For example, the default access method can be either 3GPP access or a non-3GPP access method.

[0057] For example, 3GPP access method refers to access method based on 3GPP radio protocol.

[0058] For example, non-3GPP access methods require connection to 3GPP 5G core network equipment via a Non-3GPP InterWorking Function (N3IWF). For instance, a Wireless Local Area Network (WLAN) connects to 3GPP 5G core network equipment via an N3IWF.

[0059] The "Pause Data Transmission Replication" message can be used to instruct the UE to pause data transmission replication when it is in a redundant traffic splitting mode.

[0060] For example, a pause data transmission replication message includes one or more bits that carry indication information that instructs the UE to pause data transmission replication.

[0061] In some embodiments, the UE receives a pause data transmission replication message sent by the network device.

[0062] For example, the network device is a core network device.

[0063] Optionally, the UE receives a pause data transmission replication message sent by the User Plane Function (UPF).

[0064] In the redundancy offloading mode, the UE suspends data transmission replication based on the received pause data transmission replication message.

[0065] For example, after receiving a pause data transmission replication message, the UE pauses data transmission replication after sending a response message to the network device.

[0066] If no primary access method is configured during the data transmission replication pause, a default access method needs to be set so that the UE and network equipment can use a unified default access method for data interaction during the data transmission replication pause.

[0067] In some embodiments, such as Figure 2A As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE). The method includes:

[0068] In response to receiving a pause data transmission replication message and not configuring a primary access method, set the default access method;

[0069] Determine whether the default access method set by the UE is consistent with the default access method set by the network device;

[0070] The default access method set by the UE is inconsistent with the default access method set by the network device. Change the default access method set by the UE or the network device to make the default access method set by the UE consistent with the default access method set by the network device.

[0071] For example, after deciding to suspend data transmission replication, the UE can set the default access method according to local policies or default configurations.

[0072] For example: a random strategy, which randomly selects one of the current access options as the default access method;

[0073] The default configuration allows you to specify the default access method.

[0074] After the UE determines the default access method and receives downlink data, it can be checked whether the default access method set by the UE is consistent with the default access method set by the network device.

[0075] For example, if the default access method used for downlink data is different from the default access method used for uplink data, the UE can reset the default access method to the default access method used for downlink data.

[0076] If the default access method set by the UE is consistent with the default access method set by the network device (i.e., the same), the UE and the network device will use the default access method to interact with each other during the suspension of data transmission replication.

[0077] In some embodiments, if the default access method set by the UE is different from the default access method set by the network device, the UE resets the default access method, and the reset default access method of the UE is the same as the default access method set by the network device.

[0078] In other embodiments, the default access method set by the UE is different from the default access method set by the network device. The network device resets the default access method, and the reset default access method is the same as the default access method set by the network device.

[0079] In some embodiments, the default access method set by the UE is different from the default access method set by the network device. The UE and the network device are configured to perform a check on whether the default access is consistent and to reset the default access.

[0080] By setting a default access method and checking and resetting it through the default access method used for uplink and downlink data, the default access method used by the UE for uplink data and the default access method used by the network device for downlink data can be kept consistent. This reduces the problem of service timing disorder caused by the UE and network device transmitting data through different access methods and improves the reliability of data transmission.

[0081] In some embodiments, receiving a pause data transmission replication message sent by a network device includes: receiving a pause data transmission replication message sent by a network device when congestion is detected.

[0082] In some embodiments, the pause data transmission replication message carries indication type information, which indicates the type of service that needs to be paused.

[0083] After receiving a pause data transmission copy message carrying indication type information, the UE pauses the copying of data corresponding to the service type indicated by the indication type.

[0084] There may be two or more types of data that need to be transmitted and copied. Choosing to suspend the transmission and copying of data for some service types, rather than suspending the transmission and copying of data for all service types, can improve the congestion situation and help ensure the reliability and low latency of data during communication.

[0085] In some embodiments, prior to step S1120, the information processing method further includes: receiving a recovery data transmission replication message sent by a network device.

[0086] The "Resume Data Transmission Replication" message indicates that data transmission replication should be resumed.

[0087] The data transmission replication recovery message can be a request message sent by the network device to the UE when the congestion situation improves.

[0088] The UE resumes data transmission replication based on the received resume data transmission replication message.

[0089] For example, upon receiving the message to resume data transmission replication, the UE sends a response message to the network device and resumes data transmission replication.

[0090] After resuming data transmission replication, by canceling the default access method, the access settings of the UE and network equipment before the data transmission replication was suspended can be restored, reducing communication anomalies caused by differences in access method settings before and after the data transmission replication was suspended.

[0091] like Figure 2B As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE). The method includes:

[0092] S1210: In response to the received pause data transmission replication message carrying indication information indicating the default access method, set the default access method according to the indication information.

[0093] The UE can determine the default access method from among the multiple access methods currently used by the UE based on the indication information carried in the pause data transmission replication message.

[0094] For example, if the UE is currently using multiple access methods, including 3GPP access and non-3GPP access methods, and the indication information indicates that 3GPP is the default access method, then the UE determines that the default access method is 3GPP access.

[0095] For example, the indication information includes a setting field, which indicates that 3GPP access is the default access method, in which case the UE sets the 3GPP access method as the default access method. If the setting field indicates that a non-3GPP access method is the default access method, then the UE sets the non-3GPP access method as the default access method.

[0096] The "Pause Data Transmission Replication" message can be used to instruct the UE to pause data transmission replication when it adopts a redundant offloading mode for backup transmission.

[0097] For example, a pause data transmission replication message includes one or more bits that carry indication information that instructs the UE to pause data transmission replication.

[0098] In some embodiments, the UE receives a pause data transmission replication message sent by the network device.

[0099] For example, the network device is a core network device.

[0100] Optionally, the UE receives a pause data transmission replication message sent by the User Plane Function (UPF).

[0101] In the redundancy offloading mode, the UE suspends data transmission replication based on the received pause data transmission replication message.

[0102] If the default access method set by the UE is the same as the default access method set by the network device, the UE and the network device will use the default access method to interact with each other during the suspension of data transmission and replication.

[0103] In some embodiments, if the default access method set by the UE is different from the default access method set by the network device, the UE resets the default access method, and the reset default access method of the UE is the same as the default access method set by the network device.

[0104] In other embodiments, the default access method set by the UE is different from the default access method set by the network device. The network device resets the default access method, and the reset default access method is the same as the default access method set by the network device.

[0105] In some embodiments, the default access method set by the UE is different from the default access method set by the network device. The network configuration performs a check on whether the default access is consistent and resets the default access if either the UE or the network device is configured.

[0106] By setting a default access method and checking and resetting the default access method used for uplink and downlink data, the default access method used by the UE for uplink data and the default access method used by the network device for downlink data can be kept consistent. This reduces timing issues caused by the UE and network device transmitting data through different access methods and improves the reliability of data transmission.

[0107] like Figure 2C As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE). The method includes:

[0108] S1310: In response to the fact that the received pause data transmission replication message does not carry indication information indicating the default access method, select one of the multiple access methods currently used by the UE as the default access method.

[0109] For example, the default access method can be either 3GPP access method or non-3GPP access method.

[0110] For example, 3GPP access method refers to access method based on 3GPP radio protocol.

[0111] For example, non-3GPP access refers to connecting to 3GPP 5G core network equipment via a non-3GPP interworking function (N3IWF). For instance, a Wireless Local Area Network (WLAN) connects to 3GPP 5G core network equipment via an N3IWF.

[0112] For example, the UE can set the default access method according to local policies or default configurations.

[0113] For example: a random strategy, which randomly selects one of the current access options as the default access method;

[0114] The default configuration allows you to specify the default access method.

[0115] After the UE determines the default access method and receives downlink data, it can check whether the default access method set by the UE is consistent with the default access method set by the network device.

[0116] For example, if the default access method used for downlink data is different from the default access method used for uplink data, the UE can reset the default access method to the default access method used for downlink data.

[0117] If the default access method set by the UE is the same as the default access method set by the network device, the UE and the network device will use the default access method to interact with each other during the suspension of data transmission and replication.

[0118] In some embodiments, during the suspension of data transmission replication, the UE can determine the default access method based on the received downlink data.

[0119] For example, if the downlink data received by the UE comes from the 3GPP access method, the UE knows that the default access method determined by the network device is the 3GPP access method, and the UE can set the default access method to the 3GPP access method.

[0120] For example, during the period from when data transmission is paused until the UE receives the first downlink data packet, if the UE does not have any uplink data to send, the UE can leave the default access method unset. Once the UE receives the first downlink data packet, the UE can set the default access method to be the default access method used for downlink data.

[0121] In some embodiments, during the suspension of data transmission replication, the UE may determine whether to reset the default access method based on whether the default access method used for uplink data is the same as the default access method used for downlink data.

[0122] For example, during the period from the time when data transmission is paused until the UE receives the first downlink data packet, if the UE needs to send uplink data, the UE sets the default access method. If the default access method used by the downlink data received by the UE is different from the default access method used by the uplink data, the UE can reset the default access method.

[0123] In some embodiments, the UE resets the default access method to the default access method used for downlink data transmission.

[0124] Resetting the default mode for the UE allows both the UE and network devices to use the same default access mode for data transmission, reducing timing issues caused by the UE and network devices transmitting data through different access modes and improving the reliability of data transmission.

[0125] In some embodiments, if the default access method used for uplink data is different from the default access method used for downlink data, the network device can reset the default access method.

[0126] In some embodiments, if the default access method used for uplink data is different from the default access method used for downlink data, the network device configures either the UE or the network device to perform a check on whether the default access is consistent and / or reset the default access.

[0127] For example, if the default access method used for uplink data is different from the default access method used for downlink data, the UE may not need to reset the default access method when it receives the first downlink data packet after pausing data transmission replication. If the UE receives a second downlink data packet, and the second downlink data packet uses the same default access method as the uplink data packet, it indicates that the network device has reset the default access method, and in this case, the UE does not need to reset the default access method.

[0128] For example, if the default access method used for uplink data is different from the default access method used for downlink data, and the first downlink data packet and the second downlink data packet received by the UE after pausing data transmission replication use the same default access method, it indicates that the network device has not reset the default access method. In this case, the UE can reset the default access method so that the default access method used by the UE to send uplink data is the same as the default access method used by the network device to send downlink data.

[0129] By setting a default access method, the default access method used by the UE for uplink data is kept consistent with the default access method used by the network device for downlink data, reducing the problem of service timing disorder caused by the UE and network device transmitting data through different access methods, and improving the reliability of data transmission.

[0130] The "Pause Data Transmission Replication" message can be used to instruct the UE to pause data transmission replication when it is in a redundant traffic splitting mode.

[0131] For example, a pause data transmission replication message includes one or more bits that carry indication information that instructs the UE to pause data transmission replication.

[0132] In some embodiments, the UE receives a pause data transmission replication message sent by the network device.

[0133] For example, the network device is a core network device.

[0134] Optionally, the UE receives a pause data transmission replication message sent by the User Plane Function (UPF).

[0135] In the redundancy offloading mode, the UE pauses data transmission replication based on the received pause data transmission replication message.

[0136] like Figure 2D As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE). The method includes:

[0137] S1410: In response to pausing data transmission replication, send uplink data using the default access method.

[0138] The default access method is one of the multiple access methods currently used by the UE. The default access method is used for data transmission after the UE has paused data transmission and copied the data.

[0139] For example, the default access method can be either 3GPP access or a non-3GPP access method.

[0140] For example, 3GPP access method refers to access method based on 3GPP radio protocol.

[0141] For example, non-3GPP access methods require connection to 3GPP 5G core network equipment via a Non-3GPP InterWorking Function (N3IWF). For instance, a Wireless Local Area Network (WLAN) connects to 3GPP 5G core network equipment via an N3IWF.

[0142] In some embodiments, in response to receiving a pause data transmission replication message and not configuring a primary access method, a default access method is set.

[0143] The "Pause Data Transmission Replication" message can be used to instruct the UE to pause data transmission replication when it is in a redundant traffic splitting mode.

[0144] For example, a pause data transmission replication message includes one or more bits that carry indication information that instructs the UE to pause data transmission replication.

[0145] In some embodiments, the UE receives a pause data transmission replication message sent by the network device.

[0146] For example, the network device is a core network device.

[0147] Optionally, the UE receives a pause data transmission replication message sent by the User Plane Function (UPF).

[0148] In the redundancy offloading mode, the UE pauses data transmission replication based on the received pause data transmission replication message.

[0149] In some embodiments, the UE may set the default access method to the default access method indicated by the indication information carried in the pause data transmission replication message.

[0150] In some embodiments, the pause data transmission replication message does not carry indication information, and the UE can set the default access method according to local policies or default configurations. Alternatively, the UE can determine whether to reset the default access method based on whether the default access method used for uplink data is the same as the default access method used for downlink data.

[0151] In some embodiments, during the suspension of data transmission replication, the UE may determine whether to reset the default access method based on whether the default access method used for uplink data is the same as the default access method used for downlink data.

[0152] For example, during the period from the time when data transmission is paused until the UE receives the first downlink data packet, if the UE needs to send uplink data, the UE sets the default access method. If the default access method used by the downlink data received by the UE is different from the default access method used by the uplink data, the UE needs to reset the default access method.

[0153] In some embodiments, the UE resets the default access method to the default access method used for downlink data transmission.

[0154] By checking and / or resetting the default access method used for uplink and downlink data transmission, the UE can ensure that both the UE and network devices use the same default access method to transmit data. This reduces the problem of service timing disorder caused by the UE and network devices transmitting data using different access methods, and improves the reliability of data transmission.

[0155] like Figure 2E As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE). The method includes:

[0156] S1510: Determine whether the default access method used for downlink data transmission is consistent with the default access method used for uplink data transmission, wherein downlink data is data received from the network device after data transmission replication is paused;

[0157] S1520: If the default access method used for downstream data is not the same as the default access method used for upstream data, then reset the default access method.

[0158] For example, the default access method can be either 3GPP access or a non-3GPP access method.

[0159] For example, 3GPP access method refers to access method based on 3GPP radio protocol.

[0160] For example, non-3GPP access methods require connection to the 3GPP 5G core network via a Non-3GPP InterWorking Function (N3IWF). For instance, a Wireless Local Area Network (WLAN) connects to the 3GPP 5G core network via an N3IWF.

[0161] In some embodiments, the UE resets the default access method to the default access method used for downlink data transmission.

[0162] In some embodiments, after receiving downlink data, the UE checks whether the default access method set by the UE is consistent with the default access method set by the network device.

[0163] By checking and / or resetting the default access method used for uplink and downlink data transmission, the UE can ensure that both the UE and network devices use the same default access method to transmit data. This reduces the problem of service timing disorder caused by the UE and network devices transmitting data through different access methods, and improves the reliability of data transmission.

[0164] In some embodiments, if the UE determines that the default access method used for uplink data is different from the default access method used for downlink data, the network device can also reset the default access method.

[0165] In some embodiments, if the default access method used for uplink data is different from the default access method used for downlink data, either the network configuration UE or the network device performs a check on whether the default access is consistent and / or resets the default access.

[0166] For example, if the default access method used for uplink data is different from the default access method used for downlink data, the UE does not need to reset the default access method when it receives the first downlink data packet after pausing data transmission replication. If the default access method used for the second downlink data packet has changed when the UE receives the second downlink data packet, that is, the second downlink data packet uses the same default access method as the uplink data packet, it indicates that the network device has reset the default access method, and in this case, the UE does not need to reset the default access method.

[0167] For example, if the default access method used for uplink data is different from the default access method used for downlink data, and the first downlink data packet and the second downlink data packet received by the UE after pausing data transmission replication use the same default access method, it indicates that the network device has not reset the default access method. In this case, the UE can reset the default access method so that the default access method used by the UE to send uplink data is the same as the default access method used by the network device to send downlink data.

[0168] By setting a default access method and checking and / or resetting the default access method used for uplink and downlink data, the default access method used by the UE for uplink data and the default access method used by the network device for downlink data can be kept consistent. This reduces the problem of service timing disorder caused by the UE and network device transmitting data through different access methods and improves the reliability of data transmission.

[0169] like Figure 3A As shown, this disclosure provides an information processing method, which is executed by a network device, and the method includes:

[0170] S2110: In response to sending a pause data transmission replication message and not configuring a primary access method, set a default access method; the default access method is one of the multiple access methods currently used by the user equipment (UE), and the default access method is used for data transmission after the data transmission replication is paused;

[0171] S2120: In response to sending a message to resume data transmission replication, cancel the default access mode setting.

[0172] For example, the network device is a core network device.

[0173] For example: network devices provide User Plane Functions (UPF).

[0174] For example, the multiple access methods currently used by the UE include: 3GPP access methods and non-3GPP access methods.

[0175] For example, the default access method can be either 3GPP access or a non-3GPP access method.

[0176] For example, 3GPP access method refers to access method based on 3GPP radio protocol. Generally, it needs to be connected to the core network through the access network.

[0177] For example, non-3GPP access methods require connection to 3GPP 5G core network equipment via a Non-3GPP InterWorking Function (N3IWF). For instance, a Wireless Local Area Network (WLAN) connects to 3GPP 5G core network equipment via an N3IWF.

[0178] The "Pause Data Transmission Replication" message can be used to instruct the UE to pause data transmission replication when it is in a redundant traffic splitting mode.

[0179] For example, a pause data transmission replication message includes one or more bits that carry indication information that instructs the UE to pause data transmission replication.

[0180] In some embodiments, the network device sends a pause data transmission replication message to the UE.

[0181] Optionally, the User Plane Function (UPF) sends a pause data transmission replication message to the UE.

[0182] In the redundancy offloading mode, for example, if the network device detects congestion, it can decide to suspend data transmission replication and send a pause data transmission replication message to the UE to instruct the UE to suspend data transmission replication.

[0183] If no primary access method is configured during the data transmission replication pause, a default access method needs to be set so that the UE and network equipment can use a unified default access method for data interaction during the data transmission replication pause.

[0184] For example, a network device can determine which access method is the default access method based on the actual situation of different access methods. For instance, the network device may select one of the access methods as the default access method based on the PMF measurement results to ensure that during data transmission interruptions, the network device and the UE can transmit data through the access method with better conditions.

[0185] In some embodiments, such as Figure 3A As shown, this disclosure provides an information processing method, which is executed by a network device, and the method includes:

[0186] In response to sending a pause data transmission replication message and not configuring a primary access method, set the default access method;

[0187] Determine whether the default access method set by the UE is consistent with the default access method set by the network device;

[0188] The default access method set by the UE is inconsistent with the default access method set by the network device. Change the default access method set by the UE or the network device to make the default access method set by the UE consistent with the default access method set by the network device.

[0189] For example, after determining to suspend data transmission replication, a network device can set a default access method based on local policies or default configurations.

[0190] For example: a random strategy, which randomly selects one of the current access options as the default access method;

[0191] The default configuration allows you to specify the default access method.

[0192] After the network device determines the default access method and receives downlink data, it can check whether the default access method set by the network device is consistent with the default access method set by the UE.

[0193] For example, if the default access method used for downlink data is different from the default access method used for uplink data, the network device will reset the default access method to the default access method used for uplink data.

[0194] If the default access method set by the UE is the same as the default access method set by the network device, the UE and the network device will use the default access method to interact with each other during the suspension of data transmission and replication.

[0195] In some embodiments, if the default access method set by the network device is different from the default access method set by the UE, the network device resets the default access method, and the reset default access method of the network device is the same as the default access method of the UE.

[0196] In other embodiments, the default access method set by the network device is different from the default access method set by the network device. The UE resets the default access method, and the reset default access method of the UE is the same as the default access method set by the network device.

[0197] In some embodiments, the default access method set by the UE is different from the default access method set by the network device. The network configuration performs a check on whether the default access is consistent and resets the default access if either the UE or the network device is configured.

[0198] By setting a default access method and checking and resetting the default access method used for uplink and downlink data, the default access method used by the UE for uplink data and the default access method used by the network device for downlink data can be kept consistent. This reduces the problem of service timing disorder caused by the UE and network device transmitting data through different access methods and improves the reliability of data transmission.

[0199] In some embodiments, the network device sends a pause data transmission replication message to the UE, including: the network device sending a pause data transmission replication message to the UE when congestion is detected.

[0200] In some embodiments, the pause data transmission replication message carries indication type information, which indicates the type of service that needs to be paused.

[0201] After receiving a pause data transmission copy message carrying indication type information, the UE pauses the copying of data corresponding to the service type indicated by the indication type.

[0202] There may be two or more types of data that need to be transmitted and replicated. Choosing to suspend the transmission and replication of data for some service types, rather than suspending the transmission and replication of data for all service types, can reduce the impact on data transmission and replication while improving congestion conditions. This is beneficial for ensuring the reliability and low latency of data during communication.

[0203] In some embodiments, prior to step S2120, the information processing method further includes: the network device sending a data transmission replication recovery message to the UE.

[0204] Once the network device detects that the congestion situation has improved, it can send a message to resume data transmission replication.

[0205] The "Resume Data Transmission Replication" message indicates that data transmission replication should be resumed.

[0206] The data transmission replication recovery message can be a request message sent by the network device to the UE when the congestion situation improves.

[0207] The UE resumes data transmission replication based on the received resume data transmission replication message.

[0208] After resuming data transmission replication, by canceling the default access method, the access settings of the UE and network equipment before the data transmission replication was suspended can be restored, reducing communication anomalies caused by differences in access method settings before and after the data transmission replication was suspended.

[0209] In some embodiments, the pause data transmission replication message includes an indication of the default access method.

[0210] Network devices can carry indication information in the pause data transmission copy message, and use the indication information to instruct the UE to set the default access method.

[0211] For example, the indication information includes a setting field, which indicates that 3GPP access is the default access method, in which case the UE sets 3GPP access as the default access method. If the setting field indicates that non-3GPP access is the default access method, then the UE sets 3GPP access as the default access method.

[0212] In some embodiments, the pause data transmission replication message does not include indication information for the default access method.

[0213] During the pause data transmission replication message period, the network device can set a default access method based on the default access method determined by the UE, so that the default access method determined by the network device is consistent with the access method determined by the UE.

[0214] In some embodiments, during the pause of data transmission replication, the network device can determine the default access method based on the received uplink data.

[0215] For example, if the uplink data received by the network device comes from the 3GPP access method, the network device senses that the default access method determined by the UE is the 3GPP access method, and the network device can set the default access method to the 3GPP access method.

[0216] For example, during the period from when data transmission is paused until the network device receives the first uplink data packet, if the network device does not have any downlink data to send, the network device can temporarily not set the default access method. The network device can then set the default access method based on the first uplink data received.

[0217] In some embodiments, during the suspension of data transmission replication, the network device may determine whether to reset the default access method based on whether the default access method used for uplink data is the same as the default access method used for downlink data.

[0218] For example, during the period from when data transmission replication is paused until the network device receives the first uplink data packet, if the network device needs to send downlink data, the network device sets a default access method. If the default access method used by the uplink data received by the network device is different from the default access method used by the downlink data, the network device can reset the default access method.

[0219] In some embodiments, the network device resets the default access method to the default access method used for uplink data transmission.

[0220] Resetting the default mode of network devices allows both the UE and the network device to use the same default access mode to transmit data, reducing the problem of service timing disorder caused by the UE and the network device transmitting data through different access modes, and improving the reliability of data transmission.

[0221] In some embodiments, the network device determines that the default access method used for uplink data is different from the default access method used for downlink data, and the UE can also reset the default access method.

[0222] In some embodiments, if the default access method used for uplink data is different from the default access method used for downlink data, either the UE or the network settings may choose to reset the default access method, or both may choose not to reset the default access method.

[0223] For example, if the default access method used for uplink data is different from that used for downlink data, the network device may not need to reset the default access method when it receives the first uplink data packet after pausing data transmission replication. If the network device receives the second uplink data packet and the access method of the second uplink data packet is the same as that of the downlink data packet, it indicates that the UE has reset the default access method, and in this case, the network device does not need to reset the default access method.

[0224] For example, if the default access method used for uplink data is different from the default access method used for downlink data, and the first uplink data packet and the second uplink data packet received by the network device after pausing data transmission replication use the same default access method, it indicates that the UE has not reset the default access method. In this case, the network device can reset the default access method so that the default access method used by the UE to send uplink data is the same as the default access method used by the network device to send downlink data.

[0225] like Figure 3BAs shown, this disclosure provides an information processing method, which is executed by a network device, and the method includes:

[0226] S3210: In response to pausing data transmission replication, send downlink data using the default access method.

[0227] The default access method is one of the multiple access methods currently used by the UE. The default access method is used for data transmission after the network device has paused data transmission and copied the data.

[0228] For example, the default access method can be either 3GPP access or a non-3GPP access method.

[0229] For example, 3GPP access method refers to access method based on 3GPP radio protocol. Generally, it needs to be connected to the core network through the access network.

[0230] For example, non-3GPP access methods require connection to 3GPP 5G core network equipment via a non-3GPP interworking function (N3IWF). For instance, this can be achieved through a wireless local area network (WLAN) to connect to the 3GPP 5G core network equipment.

[0231] In some embodiments, in response to sending a pause data transmission replication message and without configuring a primary access method, a default access method is set.

[0232] The "Pause Data Transmission Replication" message can be used to instruct the UE to pause data transmission replication when it is in a redundant traffic splitting mode.

[0233] For example, a pause data transmission replication message includes one or more bits that carry indication information that instructs the UE to pause data transmission replication.

[0234] In some embodiments, the network device sends a pause data transmission replication message to the UE.

[0235] For example, the network device is a core network device.

[0236] Optionally, the User Plane Function (UPF) sends a pause data transmission replication message to the UE.

[0237] In the redundancy offloading mode, the UE pauses data transmission replication based on the received pause data transmission replication message.

[0238] In some embodiments, the pause data transmission replication message does not carry indication information, and the network device can determine which access method is the default access method based on local policies.

[0239] For example, a random strategy randomly selects one of the current access options as the default access method.

[0240] After the network device determines the default access method and receives uplink data, it can check whether the default access method set by the UE is consistent with the default access method set by the network device.

[0241] For example, if the default access method used for downlink data is different from the default access method used for uplink data, the network device will reset the default access method to the default access method used for uplink data.

[0242] If the default access method set by the UE is the same as the default access method set by the network device, the UE and the network device will use the default access method to interact with each other during the suspension of data transmission and replication.

[0243] In some embodiments, the network device may carry indication information in the pause data transmission replication message, instructing the UE to set the default access method to the default access method indicated by the indication information.

[0244] like Figure 3C As shown, this disclosure provides an information processing method, which is executed by a network device, and the method includes:

[0245] S3210: Determine whether the default access method used for uplink data is consistent with the default access method used for downlink data, wherein the uplink data is received from the UE after data transmission and copying are paused;

[0246] S3220: When the default access method used for downstream data is not the same as the default access method used for upstream data, reset the default access method.

[0247] For example, the default access method can be either 3GPP access or a non-3GPP access method.

[0248] For example, 3GPP access method refers to access method based on 3GPP radio protocol.

[0249] For example, non-3GPP access methods require connection to the 3GPP 5G core network via a Non-3GPP InterWorking Function (N3IWF). For instance, a Wireless Local Area Network (WLAN) connects to the 3GPP 5G core network via an N3IWF.

[0250] In some embodiments, the network device resets the default access method to the default access method used for uplink data transmission.

[0251] In some embodiments, after receiving uplink data, the network device checks whether the default access method set by the network device is consistent with the default access method set by the UE.

[0252] By checking and / or resetting the default access method used for uplink and downlink data transmission, network devices can ensure that both the UE and the network device use the same default access method to transmit data. This reduces the problem of service timing disorder caused by the UE and the network device transmitting data through different access methods, and improves the reliability of data transmission.

[0253] In some embodiments, the network device determines that the default access method used for uplink data is different from the default access method used for downlink data, and the network device retains the already set default access method. In this case, the UE can reset the default access method.

[0254] In some embodiments, if the default access method used for uplink data differs from the default access method used for downlink data, either the network configuration UE or the network settings UE, or the network device, performs a check to determine if the default access is consistent and / or resets the default access.

[0255] For example, if the default access method used for uplink data is different from that used for downlink data, the network device may not need to reset the default access method when it receives the first uplink data packet after pausing data transmission replication. If the network device receives the second uplink data packet and the access method of the second uplink data packet is the same as that of the downlink data packet, it indicates that the UE has reset the default access method, and in this case, the network device does not need to reset the default access method.

[0256] For example, if the default access method used for uplink data is different from the default access method used for downlink data, and the first uplink data packet and the second uplink data packet received by the network device after pausing data transmission replication use the same default access method, it indicates that the UE has not reset the default access method. In this case, the network device can reset the default access method so that the default access method used by the UE to send uplink data is the same as the default access method used by the network device to send downlink data.

[0257] By setting a default access method and checking and / or resetting the default access method used for uplink and downlink data, the default access method used by the UE for uplink data and the default access method used by the network device for downlink data can be kept consistent. This reduces the problem of service timing disorder caused by the UE and network device transmitting data through different access methods and improves the reliability of data transmission.

[0258] like Figure 3DAs shown, this disclosure provides an information processing method, which is executed by a network device, and the method includes:

[0259] S3310: Reset the default access method to the default access method used for uplink data transmission.

[0260] Resetting the default mode of network devices allows both the UE and the network device to use the same default access mode to transmit data, reducing the problem of service timing disorder caused by the UE and the network device transmitting data through different access modes, and improving the reliability of data transmission.

[0261] In some embodiments, before step S3210, the information processing method further includes: in response to sending a pause data transmission replication message and not configuring a primary access method, setting a default access method; the default access method is one of multiple access methods currently used by the UE, and the default access method is used to pause data transmission after data transmission replication according to the pause data transmission auxiliary message.

[0262] For example, the default access method can be either 3GPP access or a non-3GPP access method.

[0263] For example, 3GPP access method refers to access method based on 3GPP radio protocol.

[0264] For example, non-3GPP access methods require connection to 3GPP 5G core network equipment via a Non-3GPP InterWorking Function (N3IWF). For instance, a Wireless Local Area Network (WLAN) connects to 3GPP 5G core network equipment via an N3IWF.

[0265] The "Pause Data Transmission Replication" message can be used to instruct the UE to pause data transmission replication when it adopts a redundant offloading mode for backup transmission.

[0266] For example, a pause data transmission replication message includes one or more bits that carry indication information that instructs the UE to pause data transmission replication.

[0267] In some embodiments, the network device sends a pause data transmission replication message to the UE.

[0268] Optionally, the User Plane Function (UPF) sends a pause data transmission replication message to the UE.

[0269] In some embodiments, if the default access method used for uplink data is different from the default access method used for downlink data, the network device resets the default access method, and the reset default access method of the network device is the same as the default access method of the UE.

[0270] In other embodiments, the default access method used for uplink data is different from the default access method used for downlink data. The UE resets the default access method, and the reset default access method of the UE is the same as the default access method set by the network device.

[0271] In some embodiments, the default access method used for uplink data is different from the default access method used for downlink data. Either the UE or the network settings can choose to reset the default access method, or neither can reset the default access method at the same time.

[0272] like Figure 4A As shown, this disclosure provides an information processing method, including:

[0273] S3110: Multiple Access PDU (MAPDU) Session Establishment. The UE accesses the 5GC (5G Core, 5G core network) via 3GPP access methods and non-3GPP access methods. If both the UE and the network support the ATSSS feature, the MAPDU session is established.

[0274] S3120: Send PMF-Stop Data Transmission Replication Request. If both the UE and UPF support redundant steering mode and no primary access is configured, the UE and UPF replicate all data packets of the Service Data Flow (SDF) on both access levels. If the UPF detects congestion, it sends a PMF-Stop Data Transmission Replication Request message to the UE. The PMF-Stop Data Transmission Replication Request message may include the traffic type to indicate which traffic type should have its replication suspended.

[0275] S3130: The UE selects 3GPP as the default access leg, and the UPF selects a non-3GPP access leg. When the UE receives a PMF-Pause Data Transmission Replication Request message from the UPF, the UE will stop data stream transmission replication for the specified service type. Simultaneously, since no primary access leg is configured, the UE and UPF can select the default access leg to transmit data services based on their own configurations. The default access leg selected by the UPF and UE may differ; for example, the UPF may select a non-3GPP access leg as the default access leg, while the UE may select a 3GPP access leg.

[0276] The UE sends uplink data packets to the UPF via 3GPP access. The UPF sends downlink data packets to the UE via non-3GPP access.

[0277] S3140: The UE changes its default access mode to a non-3GPP access mode. When the UE receives a downlink data packet from a non-3GPP access source, it detects that the default access mode selected by the UPF is different from the default access mode selected by the UE. The UE then changes its default access mode from 3GPP access to non-3GPP access.

[0278] This step assumes that the UE performs a check to see if the default access method is consistent. UPF can also perform this task, but only one party performs these tasks during a pause.

[0279] like Figure 4A As shown, between steps S3140 and S3150,

[0280] Both the UE and UPF use non-3GPP default access methods to transmit data. Figure 4A (Transmission of DL and UL data packets).

[0281] S3150: Send PMF-Resume Data Transmission Copy Request. The UPF decides to resume data transmission copy and sends a PMF-Resume Data Transmission Copy Request message to the UE.

[0282] S3160: When the UE receives a message (referring to PMF-Resume Data Transmission Replication Request), it resumes data transmission replication and cancels the default access mode. When the UPF receives a response message, the UPF also cancels the default access mode.

[0283] In some embodiments, when the UE receives a PMF-Pause Data Transmission Replication Request message from the UPF and no primary access is configured: the UE and the UPF determine which access method to use as the default access method based on their own configurations (implementations) so that they can send data packets respectively.

[0284] The UE and UPF may select different default access points to send data packets, which can lead to timing discrepancies between the UL and DL packets of the unified service data stream. If the access point selected by the UE for sending DL packets is different from the access point used for sending DL packets, the UE will reselect the access point for sending DL packets. This reselection can also be performed by the UPF. However, during a pause, only one party can perform this process. That is, when the default access point used for uplink data packets is inconsistent with the default access point used for downlink data packets, only one of the UE or UPF can reselect the access point.

[0285] like Figure 4B As shown, this disclosure provides an information processing method, including:

[0286] S3210: Multiple Access PDU (MA PDU) Session Establishment. The UE accesses the 5GC (5G Core, 5G core network) via 3GPP access methods and non-3GPP access methods. If both the UE and the network support the ATSSS feature, the MA PDU session is established.

[0287] S3220: Send PMF-Stop Data Transmission Replication Request (Non-3GPP Access as Default Access Method). If both the UE and UPF support redundant steering mode and no primary access is configured, the UE and UPF replicate all data packets of the Service Data Flow (SDF) on both access methods. If the UPF detects congestion, it sends a PMF-Stop Data Transmission Replication Request message to the UE. The PMF-Stop Data Transmission Replication Request message may include the traffic type to indicate which traffic type should have its data transmission replication suspended. The UPF selects non-3GPP access as the default access method and includes this indication in the PMF-Stop Data Transmission Replication Request message (meaning: non-3GPP access is the default access method).

[0288] S3230: According to the instruction, the UE selects a non-3GPP access method as the default access method. When the UE receives a PMF pause data transmission replication request message from the UPF, the UE will stop the transmission replication of the data stream of the service type. Simultaneously, since no primary access is configured, the UE selects a non-3GPP access method as the default access method.

[0289] Both the UE and UPF use non-3GPP access as the default access method to transmit data services. Figure 4B (Transmission of DL and UL data packets).

[0290] S3240: Send PMF-Resume Data Transmission Copy Request. The UPF decides to resume data transmission copy and sends a PMF-Resume Data Transmission Copy Request message to the UE.

[0291] S3250: When the UE receives a message (referring to PMF-Resume Data Transmission Replication Request), it resumes data transmission replication and cancels the default access mode. When the UPF receives a response message, the UPF also cancels the default access mode.

[0292] In some embodiments, the UPF can indicate the default access method in the PMF pause data transmission replication request message. Upon receiving the indication information, during the transmission replication pause, both the UE and the UPF send data packets using the default access method indicated in the indication information.

[0293] If the UE receives a PMF request message to resume data transmission replication, it will cancel the default access method.
