Description

TECHNICAL FIELD

[0002] At present, in the field of wireless communication technology, a communication device can send a data packet set; for example, a core network element can send a data packet set. The base station needs to regard the data packets in the data packet set as a whole, and if part of the data packets in the data packet set are not successfully sent, it means that other data packets in the data packet set do not need to be continuously sent. For the case of base station replacement, if part of the data packets in the data packet set are transmitted in the original base station, and another part of the data packets are transmitted in the new base station, it is necessary to determine the association relationship between the part of the data packets and the other part of the data packets, which increases the burden between the base stations.

[0138] In some embodiments, the PDCP layer operates by transmitting PDCP layer state information from the source base station to the destination base station when carrying a changing base station. For example... Figure 2 As shown, this disclosure provides an information processing method executed by a communication device, which includes a UE, a source base station, a destination base station, an AMF, and a UPF; the method includes the following steps:

[0139] Step S200: AMF provides mobility control information;

[0140] In an optional embodiment, before step S200, the following steps are included: user data transmission between the UE and the source base station; and / or user data transmission between the source base station and the UPF.

[0141] Step S201: The UE sends a measurement control and report to the source base station;

[0142] Step S202: The source base station decides on the handover;

[0143] Step S203: The source base station sends a handover request to the target base station.

[0144] Step S204: The target base station determines the admission control.

[0145] Step S205: The target base station sends a handover request acknowledgement to the source base station.

[0146] Step S206: The RAN initiates the handover.

[0147] In an optional embodiment, comprising: the source base station distributes buffered data and new data from the UPF.

[0148] In an optional embodiment, comprising: the UE detaches from the old cell and synchronizes with the new cell. Here, the old cell can be a cell corresponding to the source base station, and the new cell can be a cell corresponding to the target base station.

[0149] Step S207a: The source base station transfers the periodic state to the target base station.

[0150] Step S207b: The source base station transfers the sequence number (SN) state to the target base station.

[0151] In an optional embodiment, comprising: the UPF sends user data to the source base station; and / or the source base station sends user data to the target base station.

[0152] In an optional embodiment, comprising: the target base station buffers user data from the source base station.

[0153] Step S208: The RAN handover is determined to be complete.

[0154] Step S208a: The target base station sends a handover success message to the source base station.

[0155] Step S208b: The source base station sends the SN state to the target base station.

[0156] In an optional embodiment, comprising: the UPF sends user data to the source base station; and / or the source base station sends user data to the target base station.

[0157] In another optional embodiment, comprising: the UE performs transmission of user data with the target base station; and the target base station performs transmission of user data with the UPF.

[0158] Step S209: The target base station sends a path switch request to the AMF.

[0159] Step S210: The path is switched in the UPF.

[0160] In an optional embodiment, the UPF sends an end marker to the source base station; and the source base station sends the end marker to the target base station.

[0161] Step S211: The AMF sends a path switch request acknowledgement to the target base station.

[0162] Step S212: The target base station sends a UE context release message to the source base station.

[0163] In an optional embodiment, comprising: the target base station sends a UE context release message to the UE.

[0164] Here, steps S201 to S205 can be a handover preparation phase; steps S206 to S207 can be a handover execution phase; and steps S208 to S212 can be a handover completion phase.

[0165] Here, based on the above steps S207a and S207b, for the DRB without a dual active protocol stack (DAPS) configured, the source base station sends a SN status transfer message to the target base station to convey the uplink PDCP SN receiver status and the downlink PDCP SN transmitter status of the DRB (i.e. RLC AM) for which PDCP status preservation applies. The uplink PDCP SN receiver status includes at least the PDCP SN of the first missing UL PDCP SDU, and can include a bitmap of the reception status of out-of-sequence UL PDCP SDUs that the UE needs to retransmit in the target cell (if any). The downlink PDCP SN transmitter status indicates the next PDCP SN that the target base station will assign to a new PDCP SDU, and the PDCP SNs that have not yet been assigned.

[0166] For the downlink direction, the source base station delivers the PDCP layer sequence number to the target base station, so that the target base station can perform sequence number calculation and / or transmission, etc. on the new data packets obtained by the base station from the core network. At this time, the data packets in the front transmission also include data packets that have not been confirmed by the UE; that is, for the target base station, the target base station needs to send two types of data packets (at the PDCP layer): one is the data packet forwarded from the source base station, and the other is the new data packet received from the core network.

[0167] In some embodiments, in an extended reality (XR) service, data can be distinguished according to the importance of the data; for example, it can be divided into I-frame and P-frame data; wherein the I-frame is a relatively important frame, and the P-frame is a relatively unimportant frame. Here, the UE can decode the I-frame; and the P-frame cannot be decoded alone.

[0168] In some embodiments, a Protocol Data Unit (PDU) set is introduced; this PDU set can consist of multiple PDUs. Sometimes, all the data in a PDU set needs to reach the higher layer for correct decoding; while other times, all the data in a PDU set does not need to reach the higher layer for correct decoding.

[0169] In some embodiments, a PDU set consists of one or more PDUs carrying the payload of an information unit generated by the application layer (e.g., a frame or video segment for XRM services, as used in TR 26.926

[27] ). In some implementations, the application layer requires all PDUs in the PDU set to use the corresponding information unit. In other implementations, the application layer can still recover all or part of the information unit's PDUs even if some PDUs are lost.

[0170] In some embodiments, the UPF identifies the PDU set and is placed in the GTP-U header and transmitted to the RAN.

[0171] In some embodiments, the UPF identifies the PDU set for downlink (DL) PDUs at the GTP-U layer via a GTP-U header extension. The GTP-U identifier is independent of and shared by different PDU set identifiers between the access layer (AS) and the UPF. The UPF identifies the PDUs belonging to a PDU set and the following information for each PDU set: information processed within the PDU set (i.e., PDU set integration processing).

[0172] The basic parameters include at least one of the following:

[0173] PDU set serial number (SN) (Solutions 7, 8, 9, 11, 12, 14, 19, 20, 21, 22, 23, 50, 53, 55, 56);

[0174] The identifiers of the start and end PDUs in the PDU set (Solutions 11, 12, 15, 18, 21, 22, 55, 56);

[0175] PDU serial numbers in the PDU set (Solutions 11, 20, 22, 55, 56);

[0176] The number of PDUs in the PDU set (Solutions 9, 20, 50) and the size of the PDU set (in bytes);

[0177] Packet set importance or importance level;

[0178] Important PDU serial numbers in the PDU Set.

[0179] Here, the starting PDU can be implicitly indicated by the PDU serial number.

[0180] As can be seen, some basic parameters of a PDU set that UPF identifies may include at least one of the following: the sequence number of the PDU set; the sequence numbers of the start and end PDUs (i.e., the sequence number of the first or last PDU in the PDU set); the number of PDUs in the PDU set; and the sequence numbers of the PDUs in the PDU set.

[0181] In some embodiments, the base station needs to treat the data packets in a data packet set as a whole. That is, if a data packet in a data packet set is not successfully transmitted, it means that the other data packets in that data packet set (which have not yet been transmitted) do not need to be transmitted. When switching base stations, there are certain problems regarding how the two different base stations can coordinate to simultaneously process the same data packet set.

[0182] For example, part of the same data packet is transmitted at the original base station, while another part is transmitted at the new base station. In this case, for the inter-base station sequence number state transition (SN STATUS TRANSFER), it is also necessary to transmit the correlation between the data packets so that the new base station can process other data packets of the same data packet, which increases the burden between the base stations.

[0183] However, if the core network takes into account the correlation between data packets when sending them, it can send a complete data packet within a single network element as much as possible, thus avoiding the above situation. Therefore, certain enhancements are needed in the core network.

[0184] This disclosure provides an information processing method executed by a first core network element, comprising: determining a first strategy.

[0185] Optionally, the first strategy is to send the first data based on the correlation of the first data.

[0186] Optionally, a first strategy is used to instruct the sending of the first data based on the correlation of the first data.

[0187] Optionally, the first strategy can be the first mechanism or the first method.

[0188] Optionally, the first strategy can be a packet sending strategy, a packet sending mechanism, or a packet sending method.

[0189] like Figure 3 As shown, this embodiment of the disclosure provides an information processing method, executed by a first core network element, including:

[0190] Step S31: Send the first data according to the correlation of the first data.

[0191] The first core network element in this disclosure embodiment and the access network element and second core network element involved in the following embodiments can all be, but are not limited to, logical nodes or functions flexibly deployed in the network. For example, both the first core network element and the second core network element can be logical nodes or functions flexibly deployed in the core network; such as both the first core network element and the second core network element can be, but are not limited to, UPF or SMF, etc. As another example, the access network element can be a logical node or function flexibly deployed in the access network; such as the access network element can be, but is not limited to, a base station.

[0192] In some embodiments, the base station may be, but is not limited to, various types of base stations, such as, but not limited to, at least one of the following: 3G base station, 4G base station, 5G base station and other evolved base stations.

[0193] In some embodiments, the first data includes at least one of the following:

[0194] At least one data packet;

[0195] At least one data packet set; wherein a data packet set comprises one or more data packets.

[0196] In some embodiments, the correlation of the first data includes at least one of the following:

[0197] The correlation between data packets in the first data;

[0198] The correlation between data packets within the data packet set in the first data set;

[0199] The correlation between data sets in the first data.

[0200] Optionally, the correlation of the first data may also include: the correlation between data packets in the first data and data packets within the data packet set, and / or the correlation between data packets in the first data and the data packet set.

[0201] For example, the first data may include: one or more PDUs, and / or, one or more sets of PDUs.

[0202] Optionally, a data packet includes a PDU; a data packet set includes a PDU set.

[0203] In this embodiment, the first core network element sends the first data according to the correlation of the first data. This allows the first core network element to send first data with correlation, that is, to send complete data packets and / or data packet sets. This is beneficial because when the base station or other core network elements and other communication devices receive the first data, they do not need to receive the correlation information of the data packets and / or data packet sets in the first data, thereby greatly reducing the burden on the base station or other core network elements and other communication devices.

[0204] Furthermore, in this embodiment of the disclosure, the first core network element can send data packets according to the correlation of data packets, and / or send data packet sets according to the correlation of data packet sets, thereby enabling the complete transmission of at least one data packet and / or the complete transmission of at least one data packet set.

[0205] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0206] In some embodiments, step S31 includes: sending related data packets and / or data packet sets in the first data to the same access network element or the second core network element; or, based on the partial data packets of the first data received by the first core network element, sending a portion of the data packets to the second core network element; wherein the second core network element is the network element corresponding to the first core network element after the change.

[0207] like Figure 4 As shown, this embodiment of the disclosure provides an information processing method, executed by a first core network element, including:

[0208] Step S41: Send the related data packets and / or data packet sets in the first data to the same access network element or the second core network element.

[0209] This disclosure provides an information processing method, executed by a first core network element, including one of the following:

[0210] Send data packets and / or sets of data packets that are not related in the first data to different access network elements;

[0211] Send data packets and / or sets of data packets that are not related in the first data to different second core network elements.

[0212] This disclosure provides an information processing method executed by a first core network element, comprising: sending first data to the same access network element based on the correlation of first data.

[0213] For example, the data to be transmitted includes: data packet 1 and data packet 2, data packet set 1 and data packet set 2; data packet set 1 includes data packet 3 and data packet 4, and data packet set 2 includes data packet 5 and data packet 6; data packet 1 and data packet 3 and data packet 4 in data packet set 1 are related; data packet 2 and data packet 5 in data packet set 1 are related; then the first core network element can send data packet 1 and data packet 3 and data packet 4 in data packet set 1 to the first access network element (i.e., send them to the same access network element), send data packet 2 and data packet 5 in data packet set 2 to the second access network element, and send data packet 6 in data packet set 2 to the third access network element (i.e., send it to different access network elements). In this way, related data packets and / or data packet sets can be sent to the same access network element or core network element, and unrelated data packets and / or data packet sets can be sent to different access network elements or core network elements respectively, thereby ensuring that related data is transmitted completely.

[0214] This disclosure provides an information processing method, executed by a first core network element, comprising:

[0215] Based on the partial data packets of the first data received by the first core network element, the partial data packets are sent to the second core network element; wherein, the second core network element is the network element corresponding to the first core network element after the change.

[0216] For example, during the process of a first core network element sending first data to an access network element, if the first core network element sends only a portion of the first data packets to the access network element, and the first core network element changes, then the first core network element sends that portion of the data packets to the changed second core network element. For instance, the first core network element could be a first UPF, and the second core network element could be a second UPF; the access network element could be a base station. If the first UPF changes during the first data transmission, for example, switching from the first UPF to the second UPF, then the first UPF can use a forward pass to send the data packets sent in the first data to the second UPF. This ensures that related data is sent completely.

[0217] For example, the first core network element may also send data packets and / or data packets that are not related in the first data to the same access network element or the second core network element.

[0218] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0219] In some embodiments, sending related data packets and / or data packet sets in the first data to the same access network element includes: sending related data packets and / or data packet sets in the first data to the same modified access network element based on a change in the access network element.

[0220] like Figure 5 As shown, this embodiment of the disclosure provides an information processing method, executed by a first core network element, including:

[0221] Step S51: Based on the change of the access network element, send the related data packets and / or data packet sets in the first data to the same changed access network element.

[0222] In some embodiments, changes to access network elements include one of the following:

[0223] The access network element is switched from the first base station to the second base station;

[0224] The bearer type of the access network element has changed;

[0225] Adding or changing auxiliary base stations;

[0226] Changes to the logical nodes of the packet data aggregation protocol corresponding to the access network element.

[0227] In this embodiment, the first core network element and the access network element can be the first core network element and the access network element in the above embodiments.

[0228] For example, during the transmission of the first data, if the access network element receiving the first data undergoes a change, such as changing from the first base station to the second base station, then the first core network element will send related data packets and / or sets of data packets from the first data to the second base station. That is, the first core network element needs to consider the correlation of data when sending data packets to the access network element. Multiple related data packets cannot be sent separately to different access network elements.

[0229] For example, during the transmission of the first data, if the change of bearer type from primary base station to secondary base station is successful, the first core network element will send the associated first data to the secondary base station. Optionally, the primary base station and the secondary base station can be access network elements in the above embodiments.

[0230] For example, during the transmission of the first data, if a secondary base station is successfully added to the network, the first core network element will send the associated first data to the added secondary base station.

[0231] Thus, in this embodiment, in scenarios where the access network element (i.e., the network element receiving data) changes, such as access network element switching, addition or modification of secondary base stations, or changes in the bearer type corresponding to the access network element, the first data can be sent to different network elements based on its correlation, thereby achieving complete data transmission. That is, when the first core network element sends data packets to different network elements, the correlation of the data needs to be considered. Multiple data packets with correlation cannot be sent separately to different network elements.

[0232] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0233] In some embodiments, the first data includes at least one set of data packets; sending related data packets and / or data packet sets in the first data to the same access network element includes: when the PSIHI of the data packet set in the first data is a first value, sending all data packets in the data packet set to the same access network element.

[0234] like Figure 6 As shown, this embodiment of the disclosure provides an information processing method, executed by a first core network element, including:

[0235] Step S61: When the PSIHI of the data packet set in the first data is the first value, send all data packets in the data packet set to the same access network element.

[0236] Optionally, when the PSIHI of the data packet set is the first value, it indicates that all data packets in the data packet set need to be received. For example, the first value can be one or more bits, such as "1".

[0237] Optionally, when the PSIHI of the data packet set is the second value, it indicates that it is not necessary to receive all data packets in the data packet set. In this embodiment, the first core network element does not need to send the first data based on the correlation of the first data, that is, it does not need to send the data packet set based on the correlation between PDUs in the data packet set. For example, the second value can be one or more bits, such as the second value "0".

[0238] Optionally, the data packet set includes a PDU set, and the data packet includes PDUs.

[0239] Optionally, PSIHI is attribute information related to Quality of Service (QoS). For example, PSIHI is an identifier in 5G QoS Identifier (5QI).

[0240] In this embodiment of the disclosure, the first core network element determines whether to send the first data based on the correlation of the first data according to the value of PSIHI in the data packet set, so as to accurately select the appropriate sending method of the first data.

[0241] This disclosure provides an information processing method executed by a first core network element, comprising: sending related data packets and / or data packet sets in the first data to the same access network element based on a packet loss policy.

[0242] Optionally, the packet loss strategy includes at least one of the following:

[0243] Based on PSIHI as the first value, the first data is sent based on the correlation of the first data;

[0244] The first data is sent based on the second value of PSIHI, without relying on the correlation of the first data.

[0245] Optionally, the correlation of the first data indicated when PSIHI is a first value is higher than the correlation of the first data indicated when PSIHI is a second value. Optionally, the first data includes at least one set of PDUs.

[0246] In this way, the first core network element can also select the appropriate method for sending the first data based on the packet loss strategy. For example, it can send the first data with relatively strong correlation in its entirety, or it can choose not to send the first data with relatively weak correlation in its entirety.

[0247] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0248] like Figure 7 As shown, this embodiment of the disclosure provides an information processing method, executed by a first core network element, including:

[0249] Step S71: Send at least one end identifier to the second core network element or access network element. The end identifier is used to indicate that the related data packets and / or data packet sets in the first data packet have been sent.

[0250] In some embodiments of this disclosure, the first core network element, the second core network element, and the access network element are respectively the first core network element, the second core network element, and the access network element in the above embodiments; the first data is the first data in the above embodiments; and the correlation of the first data is the correlation of the first data in the above embodiments.

[0251] Optionally, after step S31, step S71 is performed.

[0252] Optionally, an end marker corresponds to the transmission of one complete first data.

[0253] Optionally, the end marker can be either an endmaker instruction or an endmaker.

[0254] For example, after the first core network element completely sends a related data packet and / or data packet set to the access network element, it sends an end identifier to the access network element. Optionally, the first core network element may also completely send other related data packets and / or data packet sets to the access network element before sending an end identifier to the access network element.

[0255] For example, after the first core network element sends a related data packet and / or data packet set completely to the second core network element, it sends an end identifier to the core network element. Optionally, the second core network element may also send other related data packets and / or data packet sets completely to the second core network element before sending an end identifier to the core network element.

[0256] In this embodiment of the disclosure, after sending complete first data to the access network element or the second core network element, an end identifier can be sent so that the access network element or the second core network element knows that complete first data has been received.

[0257] This disclosure provides an information processing method executed by a first core network element, comprising: sending an end identifier after each PDU set has been sent to a second core network element or an access network element; the end identifier indicates that the corresponding PDU set has been sent. This ensures the complete transmission of each PDU set and also notifies the second core network element or access network element that each PDU set has been sent.

[0258] In some embodiments, before step S71, the method includes: receiving indication information sent by a base station, the indication information being used to indicate that the access network element accessed by the UE has changed.

[0259] This disclosure provides an information processing method executed by a first core network element, comprising: receiving indication information sent by a base station, the indication information being used to indicate a change in the access network element accessed by the UE. Optionally, the access network element is a base station.

[0260] For example, the access network element changes from a first base station to a second base station; the first core network element receives an indication from the second base station, which indicates that the base station accessed by the UE has changed from the first base station to the second base station; the first core network element sends an end identifier to the second base station. Optionally, the first core network element may also receive indication information sent by the first base station before the change from the first base station to the second base station.

[0261] In this embodiment of the disclosure, if the access network element accessed by the UE changes, for example, from the first base station to the second base station, the second base station can inform the first core network element that the access network accessed by the UE has changed, thereby enabling the first core network element to send an end identifier to the access network element to ensure the complete transmission of the first data.

[0262] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0263] like Figure 8 As shown, this embodiment of the disclosure provides an information processing method, executed by a first core network element, including:

[0264] Step S81: Send notification information to the access network element, wherein the notification information is used to indicate that the first core network element has the ability to send the first data according to the correlation of the first data.

[0265] Optionally, the notification information is used to indicate that the first core network element has the capability to support the first policy.

[0266] In some embodiments of this disclosure, the first core network element and the access network element are respectively the first core network element and the access network element in the above embodiments; the first data is the first data in the above embodiments; and the correlation of the first data is the correlation of the first data in the above embodiments.

[0267] In this embodiment of the disclosure, a notification message can be sent from the first core network element to the access network element to inform the access network element that the first core network element has the capability to send the first data according to the correlation of the first data; this is beneficial for the access network element to not need to send auxiliary information such as packet loss to the target base station when the first data is forwarded.

[0268] In some embodiments, a first core network element sends a notification message to a second core network element. In this way, the first core network element can also notify other core network elements that it has the capability to send first data based on the correlation of the first data.

[0269] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0270] The following information processing method is executed by an access network element, and is similar to the information processing method executed by the first core network element described above.

[0310] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0311] To further explain any of the embodiments of this disclosure, several specific embodiments are provided below.

[0312] Example 1

[0313] The information processing method disclosed herein includes the following steps:

[0314] In some embodiments, a mechanism is protected for a core network element to send data packets based on the dependency between data packets. Optionally, the data packets may be the first data in the foregoing embodiments.

[0315] Optionally, the core network element is a UPF or an SMF. Optionally, the core network element is the first core network element in the aforementioned embodiments.

[0316] Optionally, a data packet may include at least one data packet, or it may include a packet set consisting of at least one data packet.

[0317] Optionally, the correlation between packets includes the correlation between packets within a packet set (Intra packet set dependency) and the correlation between packets between packet sets (Inter packet set dependency).

[0318] In some embodiments, the core network element sending data packets based on the dependency between data packets includes directing one or more data packets from a packet set that have a dependency relationship (or correlation) to the same target network element. Optionally, the target network element can be an access network element or a second core network element as described in the foregoing embodiments.

[0319] Optionally, data packets with related relationships can be sent within the same network element, that is, data packets with related relationships are not sent separately to different network elements.

[0320] Optionally, the target network element can be a base station of the access network or other network elements of the core network.

[0321] Optionally, if a core network element changes during data transmission (e.g., switching from a first core network element to a second core network element, such as a UPF change), a data forwarding method can be used to ensure the complete transmission of related data. For example, if the first core network element receives a partial data packet set but cannot wait for an end indication of the data packet set, it means that the data packet set has not been received completely. In this case, the data in the incompletely received data packet set can be forwarded to the second core network element, which will then continue to transmit the data packet set to the access network element.

[0322] In some embodiments, the core network element sending data packets to the same target network element based on the dependency between data packets includes ensuring the integrity of the data packets when the target network element changes (from the first base station to the second base station). Optionally, the target network element is the access network element or the second core network element in the foregoing embodiments.

[0323] Optionally, changes to the target network element during data transmission include scenarios such as handover, SN addition / modification, etc.

[0324] Optionally, changes to the target network element during data transmission include scenarios involving bearer type changes, specifically (examples are given below):

[0325] During Evolved Universal Terrestrial Radio Access (E-UTRA) to New Radio (NR) Dual Connectivity (EN-DC) activities, for the Evolved Radio Access Bearer (E-RAB), the bearer type is changed from or to the Master Node (MN) to or from the Secondary Node (SN) for bearer termination.

[0326] For Multi-RAT DualConnectivity (MR-DC) with a 5G core network (5G Core, 5GC), user data forwarding can be performed between NG-RAN nodes whenever the logical node supporting the PDCP entity changes.

[0327] When SN changes involve the entire configuration;

[0328] For mobile scenarios involving more than two RAN nodes;

[0329] For MR-DC with 5GC, QoS flow offloading within a PDU session can be performed between NG-RAN nodes.

[0330] A change in the target network element during data transmission means that, for core network elements, the data transmission channel needs to be switched from the changed target network element.

[0331] In some embodiments, the process of a core network element sending data packets to the same target network element based on the dependency between data packets may further include additional limiting conditions (such as packet loss policies). Optionally, the target network element is the access network element in the foregoing embodiments.

[0332] Optionally, this operation is only performed if the PHISI attribute of the packet is set to 1. For example, PHISI indicates that all packets in a packet set need to be received simultaneously at the application layer, which means that the packets in the packet set are strongly correlated.

[0333] Optionally, if the PHISI attribute of the data packet is set to 0, then it is not necessary to perform the operation according to correlation. This correlation refers to the correlation between data packets in the foregoing embodiments.

[0334] Optionally, the PDU Set Comprehensive Processing Indicator (PSIHI) indicates whether the application layer needs all PDUs in the PDU set to use the PDU set. When PSIHI is set for a QoS flow, if one PDU in the PDU set is known to be lost, the remaining PDUs in that PDU set can be considered as no longer needed by the application and can be discarded.

[0335] In some embodiments, the mechanism by which core network elements send data packets based on the dependency between data packets can also take into account the dependency between data packets when sending the endmaker instruction.

[0336] Optionally, when a core network element needs to send an endmaker instruction to a target network element, it needs to consider that one or more data packets in a related packet set, or one or more data packets in a related packet set, have been completely sent to the same target network element before sending the endmaker instruction. Optionally, the endmaker instruction will not be sent in the middle of related data packets or before the related data packets have been completely sent. Optionally, the core network element is a UPF, and the target network element is the access network element in the aforementioned embodiments, such as a base station. Optionally, the core network element is an SMF, and the target network element is the second core network element in the aforementioned embodiments, such as a UPF.

[0337] In some embodiments, because the target network element changes during data transmission (e.g., switching), it means that for the core network element, the data transmission channel needs to be switched from the changed target network element (e.g., from the first base station to the second base station). This involves endmaker transmission; that is, the core network element first sends one or more data packets from one or more related data packet sets to the same target network element (e.g., the first base station) completely, and then sends an endmaker to the first proclamation. Afterwards, it continues to transmit data to the second base station.

[0338] Optionally, there can be one or more endmarkers.

[0339] Optionally, the core network element sending the endmaker message could actually be receiving a base station indication; for example, the UPF receiving an indication that the UE has connected to a new base station. Optionally, this indication could be the indication information described in the aforementioned embodiments. Optionally, this example could be expressed as:

[0340] The target gNB sends a path switch request message to the AMF to trigger the 5GC to switch the DL data path to the target gNB and establish a Next Generation Core Network (NG-C) interface instance to the target gNB. The 5GC switches the DL data path to the target gNB. The UPF sends one or more "end marker" packets to the source gNB on the old path via a PDU session or tunnel, and can then release any user plane or transport network layer (TNL) resources to the source gNB.

[0341] In some embodiments, core network elements can notify the base station of their ability to send data packets based on the dependency between data packets. Thus, when forwarding data packets, the base station does not need to notify the target base station of packet loss auxiliary information.

[0342] For details of the above implementation methods, please refer to the descriptions of the first core network element side and / or the second core network element side and / or the access network element side, which will not be repeated here.
