[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 202410405871.5 filed in China on April 3, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of interactive multimedia technology, and in particular to a bearer management method and apparatus, communication equipment, program product, and storage medium. Background Art

[0004] In 5G (Fifth Generation Mobile Communication Technology) networks, gNodeBs map Quality of Service (QoS) flows to bearers. The mapping between QoS flows and radio bearers (RBs) can be either many-to-one or one-to-one, meaning that multiple or one QoS flows can be mapped to a single RB. Related technologies typically map multiple QoS flows with the same or similar Quality of Service (QoS) Flow IDs (QFIs) to a single RB or a single logical channel (LC) or logical channel group (LCG). Mapping multiple QoS flows with significantly different QFIs, such as those with significantly different characteristics like latency, reliability, rate, and synchronization, to a single RB or a single LC or LCG is prohibited. However, with the increasing complexity of network applications and environments, this QoS flow relationship cannot meet service requirements, such as the need for joint processing of multiple flows with QoS collaboration, packet error rate, latency, jitter, synchronization, and reliability.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0034] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

It should also be understood that in the embodiments of the present disclosure, the “protocol” can refer to a standard protocol in the communication field, for example, it can include the NR protocol and related protocols used in future communication systems, and the present disclosure does not limit this.

[0037] To facilitate understanding of the technical solutions of the embodiments of the present disclosure, the relevant technologies of the embodiments of the present disclosure are described below. The following relevant technologies are optional solutions that can be arbitrarily combined with the technical solutions of the embodiments of the present disclosure, and they all fall within the protection scope of the embodiments of the present disclosure.

[0038] Figure 1 is a schematic diagram of the 5G QoS model architecture provided by an embodiment of the present disclosure. The network elements and devices involved in Figure 1 are: User Equipment (UE), Base Station (gNodeB), and User Plane Function (UPF), where UE and gNodeB belong to the Next Generation Radio Access Network / 5G Radio Access Network (NG RAN), and UPF belongs to the 5G core network (5G core, 5GC). For each UE, 5GC can establish one or more Protocol Data Unit (PDU) sessions. For each UE, NG RAN can establish one or more RBs for each PDU session. In related technologies, multiple QoS flows can be mapped to one RB, but one QoS flow cannot be mapped to multiple RBs. In the 5G network, there is still a bearer between the gNodeB and the UE, but the concept of bearer is no longer used between the gNodeB and the core network. The Evolved Packet System (EPS) bearer in the non-standalone network (5G Non-Standalone Architecture, NSA) is transformed into a QoS Flow. QoS Flow is the finest granularity of QoS control from the 5G core network to the terminal. Each QoS Flow is identified by a QoS Flow ID (QFI). Within a PDU session, the QFI of each QoS Flow is unique. The core network will notify the gNodeB of the 5G QoS identifier (5G QoS Identifier, 5QI) corresponding to each QoS Flow, which is used to specify the QoS attributes of this QoS Flow. The gNodeB will map the QoS Flow to the bearer. The mapping relationship between QoS Flow and radio bearer can be many-to-one or one-to-one.

[0039] In related technologies, multiple QoS flows can be mapped to a single RB, but a single QoS flow cannot be mapped to multiple RBs. However, with the increasing complexity of network applications and network environments, dynamic switching between multiple RBs is required. To this end, the following technical solutions are proposed in the embodiments of the present disclosure.

[0040] To facilitate understanding of the technical solutions of the embodiments of the present disclosure, the technical solutions of the present disclosure are described in detail below through specific embodiments. The above related technologies can be combined with the technical solutions of the embodiments of the present disclosure as optional solutions, and all of them fall within the scope of protection of the embodiments of the present disclosure. The embodiments of the present disclosure include at least part of the following contents.

[0041] FIG2 is a flow chart of a bearer management method provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG2 , the bearer management method includes the following steps:

[0042] Step 201: The terminal sends and / or receives data of P1 streams, where P1 is an integer greater than 0, and the P1 streams are associated with each other.

[0043] In some implementations, the associated P1 flows have at least one of the following definitions:

[0044] When the flow is a QoS flow, P1 associated QoS flows form a Service Progress. This allows for more efficient management of the P1 associated flows. A Service Progress in this article may also be called a QoS flow set or a virtual QoS flow.

[0045] When the flow is a QoS flow, P1 QoS flows with an associated relationship are respectively mapped into N RBs, where N is an integer greater than 0.

[0046] When the flow is a QoS flow, the P1 QoS flows with an associated relationship are mapped into a super RB (S-RB). In conventional technology, multiple QoS flows mapped to one RB are required to have the same QFI and are not required to have an associated relationship.

[0047] When the flow is a QoS flow, a service process consisting of P1 associated QoS flows is mapped into a super RB; the difference from the previous one is that what the RAN side and the core network interface see is the service process, not the QoS flow.

[0048] When the flow is a radio bearer RB, the associated P1 RBs are mapped into a super RB (S-RB). Unlike the previous method, where merging occurs in the core network, this method performs the association or merging at the RAN PDCP / RLC layer. This allows for more efficient processing of data from associated flows with different QFIs, importance levels, or priorities. Data cannot be sorted or time-aligned within different RBs.

[0049] The super RB (S-RB, Super RB) in this article can also be called RB set, virtual RB, etc., or it can still be called RB.

[0050] The super logical channel (S-LC) in this article can also be called an LC set or a virtual LC, or it can still be called an LC.

[0051] When the flow is a logical channel (LC), the associated P1 LCs are mapped into a super logical channel (S-LC). The difference from the previous example is that the previous example performs the merging process in the core network, while the association process or merging process is performed in the RLC / MAC layer of the RAN.

[0052] When the flow is a PDU set packet, P1 PDU sets with an associated relationship are mapped into a super PDU set packet (Super Protocol Data Unit, S-PDU Set); the difference from the previous one is that more consideration is given to the association relationship between data belonging to the same application layer characteristics, for example, a PDU set is a type of frame.

[0053] Step 202: The terminal processes the data of the P1 flows according to the definition using at least one of a service process, an RB, a super RB, an LC, a super LC, a PDU aggregate package, and a super PDU aggregate package.

[0054] In some implementations, for the case where the associated P1 QoS flows are respectively mapped to N RBs, the method further includes:

[0055] The terminal switches the N RBs to M RBs, where N and M are different or the same positive integers, and the associated P1 streams are mapped to the N RBs, and the associated P2 streams are mapped to the M RBs; wherein:

[0056] The N RBs are different from the M RBs in at least one RB; and / or,

[0057] At least one of the P1 streams and the P2 streams is different, or the P1 stream and the P2 stream are the same, and P1 and P2 are different or the same positive integers; and / or,

[0058] The N RBs correspond to at least one of an L1 logical channel, an L2 cell group (CG) / semi-persistent scheduling (SPS) configuration, and an L5 discontinuous reception (DRX) configuration, where L1, L2, and L5 are different or identical positive integers. The M RBs correspond to at least one of an L3 logical channel, an L4 CG / SPS configuration, and an L6 DRX configuration, where L3, L4, and L6 are different or identical positive integers. These configurations correspond to the association and QoS characteristics of different flows in each super RB.

[0059] In the present disclosure, P1 and P2, P1 and N, P2 and M are different or the same positive integers.

[0060] In some embodiments, for the case where the associated P1 QoS flows are mapped to a super RB, or the service process is mapped to a super RB, or the associated P1 RBs are mapped to a super RB, the method further includes:

[0061] The terminal switches the first super RB to the second super RB, where the first super RB is formed by N RBs and the second super RB is formed by M RBs, and N and M are different or the same positive integers; wherein: P1 streams with an associated relationship are mapped to the first super RB, and P2 streams with an associated relationship are mapped to the second super RB; or, the first service process is mapped to the first super RB, and the second service process is mapped to the second super RB; or, P1 RBs with an associated relationship are projected onto the first super RB, and P2 RBs with an associated relationship are projected onto the second super RB; P1 and P2 are different or the same positive integers.

[0062] In some embodiments, the super RB satisfies at least one of the following:

[0063] Prioritize uplink authorization to data in the same super RB; prioritize uplink authorization to data that arrives early in the same super RB and has the highest importance parameter level; prioritize uplink authorization to multiple data in the super RB whose QoS collaborative characterization QoS parameter values ​​are the same, or whose QoS parameter difference is less than or equal to a set threshold; wherein the QoS parameters include data with the highest importance parameter level in at least one of packet error rate, delay, jitter, data arrival time, synchronization accuracy, and reliability; prioritize uplink authorization to data in the super RB that has integrity requirements and / or multi-stream collaborative processing requirements with one or more packets that have been successfully processed; prioritize uplink authorization to data that arrives early in the super RB and has the highest quality requirement in layer parameters; prioritize uplink authorization to data in the super RB that has the highest quality requirement in layer parameters or whose difference between data cache delay and PDB is less than or equal to a set threshold ; Give priority to different or the same logical channels in the same super RB; Give priority to the logical channel corresponding to the data that arrives early and has the highest importance parameter level in a super RB; Give priority to the logical channel corresponding to multiple data in a super RB whose QoS collaborative characterization QoS parameters have the same value, or the difference in QoS parameters is less than or equal to the set threshold; wherein the QoS parameters include the data with the highest importance parameter level in at least one of the following: packet error rate, delay, jitter, data arrival time, synchronization accuracy, and reliability; Give priority to the logical channel corresponding to the data in a super RB that has integrity requirements and / or multi-stream collaborative processing requirements for one or more packets that have been successfully processed; Give priority to the data that arrives early in a super RB and has the highest quality requirements in the layer parameters; Give priority to the data in a super RB that has the highest quality requirements in the layer parameters or the difference between the data cache delay and the PDB is less than or equal to the set threshold.

[0064] In some embodiments, the super RB corresponds to at least one of the following configurations: L1 logical channels, L2 CG / SPS configurations, and L5 DRX configurations, where L1, L2, and L5 are different or identical positive integers. These configurations correspond to the associations and QoS characteristics of different flows in each super RB.

[0065] In some implementations, the data of the one super RB satisfies at least one of the following:

[0066] Use the same and / or adjacent transport blocks (Transport Block, TB); use the transmission resources indicated by the same and / or adjacent uplink grants (Uplink Grant, UL Grant); select the same LC or super LC.

[0067] In some embodiments, the association relationship includes at least one of the following:

[0068] Quality of service (QoS) collaboration; uplink and downlink data transmission times satisfying certain conditions; time synchronization; belonging to a QoS flow; belonging to a protocol data unit (PDU) set (PDU SET); belonging to a radio bearer; belonging to an application server; having the same identifier; wherein QoS collaboration characterizes that the values ​​of QoS parameters are the same, or the difference in QoS parameters is less than or equal to a set threshold; the QoS parameters include at least one of packet error rate, delay, jitter, data arrival time, synchronization accuracy, and reliability.

[0069] In some embodiments, the method further comprises:

[0070] receiving first information sent by a second communication device, where the first information is used to indicate a definition of an association relationship between the P1 flows and / or resource information associated with the P1 flows;

[0071] The resource information associated with the P1 flows includes at least one of the following: super RB, super LC, LC, LCG, configuration authorization, SPS, DRX, and antenna resources shared by the P1 flows;

[0072] or,

[0073] Second information sent by a second communication device is received, where the second information is used to indicate an association relationship between the P1 flows, where the P1 flows are P1 QoS flows or P1 logical channels.

[0074] In some embodiments, the method further comprises:

[0075] Third information sent to the second communication device, the third information being used to indicate an association relationship between the P1 flows; wherein the P1 flows are P1 QoS flows;

[0076] Fourth information sent by the second communication device is received, where the fourth information is used to indicate an association relationship between Q1 flows; wherein the Q1 flows are Q1 logical channels, and a mapping relationship exists between the P1 flows and the Q1 flows.

[0077] In some implementations, the QFI values ​​of the P1 flows are the same or different.

[0078] In some embodiments, the flow is at least one of a QoS flow, an IP flow, a sub-QoS flow, a service, a PDU session, a service data flow, a wireless bearer, a logical channel, a PDU aggregate package, a PDU, and a sampling flow, and the present disclosure does not make any specific limitations on this.

[0079] It should be noted that the service progress can also be called a QoS flow set or a virtual QoS flow. The super RB (S-RB) can also be called an RB set or a virtual RB. Or it can still be called an RB. The super logical channel (S-LC) can also be called an LC set or a virtual LC. Data processing includes at least one of the following operations: sending, receiving, adding headers, removing headers, compression, segmentation, concatenation, sorting, priority processing, error correction, packet loss, scheduling, logical channel selection, UL authorization selection, packet assembly, retransmission, resource allocation, and submission to the upper layer. Among them, the QFI values ​​of P1 flows can be the same or different.

[0080] In some implementations, a terminal may switch N RBs to M RBs based on network signaling, where the network device may be a base station that serves as a serving base station for the terminal. The terminal may also autonomously switch N RBs to M RBs, or the terminal may switch N RBs to M RBs based on an event trigger. This is described below.

[0081] Solution 1: Terminal switching based on network signaling

[0082] Solution 1-1) In some embodiments, a terminal receives first signaling sent by a network device, where the first signaling is used to instruct the terminal to switch N RBs to M RBs; the terminal switches the N RBs to M RBs when a switching condition is met; wherein the switching condition is predefined or protocol-defined or determined based on an RB switching rule carried by the first signaling. In some embodiments, the first signaling may be downlink control information (DCI) or a media access control control element (MAC CE).

[0083] In some embodiments, the terminal receives second signaling sent by the network device, where the second signaling indicates a switching condition for the terminal to switch N RBs to M RBs. If the switching condition is met, the terminal switches the N RBs to M RBs. In some embodiments, the second signaling may be a DCI or a MAC CE.

[0084] In some implementations, when a terminal performs a handover based on network signaling, the first signaling and / or the second signaling may be determined based on a service collaboration requirement, where the service collaboration requirement includes an uplink service collaboration requirement and / or a downlink service collaboration requirement, wherein the uplink service collaboration requirement is obtained from the terminal, and the downlink service collaboration requirement is obtained from the core network and / or an application server. The first signaling and / or the second signaling are determined based on the uplink service collaboration requirement and / or the downlink service collaboration requirement.

[0085] In some implementations, the first signaling and / or the second signaling carries first indication information, and the first indication information is used to instruct the terminal to switch N RBs to M RBs. That is, when RB switching is required, the network device instructs the terminal on how to perform RB switching.

[0086] In some embodiments, the first signaling and / or the second signaling carries second indication information, where the second indication information is used to indicate RBs corresponding to one or more times; wherein the one or more times include a first time, and the RBs corresponding to the first time are M RBs. That is, the network device notifies the terminal how to perform RB switching at different times. Exemplarily, the second indication information indicates that the RBs corresponding to the first time are M RBs, i.e., the terminal switches N RBs to M RBs at the first time; or the second indication information indicates RBs corresponding to multiple times, and the terminal obtains RBs corresponding to multiple times at one time, thereby performing RB switching at the times corresponding to the multiple times.

[0087] In some implementations, the first signaling and / or the second signaling carries third indication information, and the third indication information is used to instruct the terminal to switch from the first association relationship to the second association relationship, where the first association relationship is an association relationship corresponding to N RBs, and the second association relationship is an association relationship corresponding to M RBs. That is, RB association relationships are introduced in the embodiments of the present disclosure, and RB switching is achieved by switching the association relationships.

[0088] In some embodiments, the first signaling and / or the second signaling carries fourth indication information, and the fourth indication information is used to indicate the association relationship corresponding to one or more times; wherein the one or more times include the second time, and the association relationship corresponding to the second time is the association relationship corresponding to M RBs. That is, the network device notifies the terminal how to switch the association relationship at different times; the association relationship includes the association relationship between the logical channels corresponding to the RBs and / or the association relationship between the cell groups / SPSs corresponding to the RBs. Exemplarily, the fourth indication information indicates that the association relationship corresponding to the second time is the association relationship corresponding to M RBs, that is, the terminal switches from the association relationship corresponding to N RBs to the association relationship corresponding to M RBs at the second time; or the fourth indication information indicates the association relationship corresponding to multiple times, then the terminal obtains the association relationship corresponding to multiple times at one time, and therefore, the terminal switches the association relationship at the times corresponding to the multiple times.

[0089] It should be noted that the first time and the second time may be the same time or may not be the same time, and this disclosure does not make any specific limitation on this.

[0090] Solution 2: Terminal autonomous switching

[0091] In some implementations, the terminal switches N RBs to M RBs based on service collaboration requirements, where the service collaboration requirements include uplink service collaboration requirements and / or downlink service collaboration requirements, where the uplink service collaboration requirements are obtained from the terminal and the downlink service collaboration requirements are obtained from the core network and / or application server.

[0092] In some implementations, when the terminal switches autonomously, the terminal obtains uplink service collaboration requirements from its own application layer and downlink service collaboration requirements from the core network and / or application server; and determines how to perform RB switching based on the uplink service collaboration requirements and / or downlink service collaboration requirements.

[0093] In some embodiments, after the terminal switches N RBs to M RBs, the terminal sends a fifth signaling to the network device, where the fifth signaling is used to indicate the switching result of the terminal. In some embodiments, the fifth signaling may be uplink control information (UCI) or MAC CE. The switching result includes information such as whether the switching is successful and / or the RBs after switching, which is not specifically limited in this disclosure.

[0094] Solution 3: Terminal switching based on event triggering

[0095] In some embodiments, the terminal may further switch N RBs to M RBs based on an event trigger. The aforementioned trigger event includes one or more of the following: switching from PDU management to PDU set management; the terminal switching from a first channel environment to a second channel environment; the terminal switching from a first quality of experience (QoE) to a second QoE; the terminal switching from a first service source to a second service source; the terminal switching from a first type of network to a second type of network, for example, the terminal switching from a non-terrestrial network (NTN) to a terrestrial network (NTN). the terminal switches from a first power supply state to a second power supply state, for example, the terminal switches from a plugged in state to an unplugged state, or from an unplugged state to a plugged in state, or from a first power state to a second power state, etc., the present disclosure does not make any specific limitations on this; the terminal switches from a first network coverage state to a second network coverage state, for example, the terminal switches between satellites in different orbits, such as switching from a first orbit satellite to a second orbit satellite, or switching under different coverage conditions of a cell, such as switching from the coverage range of a first cell to the coverage range of a second cell, etc., the present disclosure does not make any specific limitations on this; the access type of the target cell for cell switching by the terminal is an air-to-ground communication (ATG) type or a satellite type; the target cell for cell switching by the terminal supports and / or starts a PDU set management function; the target cell for cell switching by the terminal supports and / or starts a telepathic function; the terminal switches from a first RRC state to a second RRC state, for example, the terminal switches from a radio resource control protocol (Radio Resource Control Protocol) to a radio resource control protocol (Radio Resource Control Protocol). The present disclosure does not specifically limit this.

[0096] In other embodiments, the terminal may switch the first super RB to the second super RB. FIG3 is a second flow chart of the bearer management method provided in an embodiment of the present disclosure. As shown in FIG3 , switching from super RB1 to super RB2 may be performed in a specific switching scheme of at least one of the following:

[0098] Scheme 4-1) In some embodiments, the terminal receives a third signaling sent by a network device, and the third signaling is used to instruct the terminal to switch the first super RB to the second super RB; the terminal switches from the first super RB to the second super RB when the switching condition is met; wherein the switching condition is predefined or protocol-defined or determined based on the super RB switching rule carried by the third signaling.

[0099] Solution 4-2) The terminal receives a fourth signaling sent by a network device, and the fourth signaling is used to indicate the switching conditions for the terminal to switch from the first super RB to the second super RB; when the switching conditions are met, the terminal switches from the first super RB to the second super RB.

[0100] In some implementations, the third signaling and / or the fourth signaling carries fifth indication information, where the fifth indication information is used to instruct the terminal to switch from the first super RB to the second super RB.

[0101] In some embodiments, the third signaling and / or the fourth signaling carries sixth indication information, and the sixth indication information is used to indicate super RBs corresponding to one or more times; wherein the one or more times include a first time, and the super RB corresponding to the first time is the second super RB.

[0102] In some embodiments, the third signaling and / or the fourth signaling carries seventh indication information, and the seventh indication information is used to instruct the terminal to switch from a first association relationship to a second association relationship, where the first association relationship is the association relationship corresponding to the first super RB, and the second association relationship is the association relationship corresponding to the second super RB.

[0103] In some embodiments, the third signaling and / or the fourth signaling carries eighth indication information, and the eighth indication information is used to indicate the association relationship corresponding to one or more times; wherein the one or more times include a second time, and the association relationship corresponding to the second time is the association relationship corresponding to the second super RB; the association relationship includes the association relationship between the logical channels corresponding to the super RB and / or the association relationship between the cell groups / SPS corresponding to the super RB.

[0104] Solution 5): The terminal switches autonomously

[0105] In some implementations, the terminal switches the first super RB to the second super RB based on a service coordination requirement; the service coordination requirement is as described above and will not be repeated here.

[0106] In some embodiments, after the terminal switches N RBs to M RBs, the terminal sends a fifth signaling to the network device, where the fifth signaling is used to indicate the switching result of the terminal. In some embodiments, the fifth signaling may be uplink control information (UCI) or MAC CE. The switching result includes information such as whether the switching is successful and / or the RBs after switching, which is not specifically limited in this disclosure.

[0107] Solution 6): Terminal switching based on event triggering

[0108] In some implementations, the terminal switches the first super RB to the second super RB based on a triggering event. The event is as described above and will not be described in detail here.

[0109] The technical solution of the embodiment of the present disclosure is that the terminal sends and / or receives data of P1 streams, P1 is an integer greater than 0, and the P1 streams are associated with each other; wherein the P1 streams with an associated relationship have at least one of the following definitions: when the stream is a QoS stream, the P1 QoS streams with an associated relationship form a service process; when the stream is a QoS stream, the P1 QoS streams with an associated relationship are respectively mapped into N RBs, N is an integer greater than 0; when the stream is a QoS stream, the P1 QoS streams with an associated relationship are mapped into a super RB; when the stream is a QoS stream The service process consisting of P1 associated QoS flows is mapped into a super RB; when the flow is a radio bearer RB, the P1 associated RBs are mapped into a super RB; when the flow is a logical channel LC, the P1 associated LCs are mapped into a super LC; when the flow is a PDU aggregate package, the P1 associated PDU aggregate packages are mapped into a super PDU aggregate package; according to the definition, the data of the P1 flows is processed using at least one of the service process, RB, super RB, LC, super LC, PDU aggregate package, and super PDU aggregate package. In this way, service requirements can be met based on the P1 associated flows.

[0110] Based on the above embodiments, the bearer management method provided by the embodiments of the present disclosure is further described. The technical solution of the embodiments of the present disclosure is described below with reference to specific application examples.

[0111] In multimodal services for Extended Reality (XR), some QoS flows require QoS coordination or time synchronization with different QoS flows at different time points, with time granularity in milliseconds and seconds. For example, in a live XR concert, at time T1, QoS flow 1 (the data flow generated by the piano device) requires QoS coordination or time synchronization with QoS flow 2 (the data flow generated by the flute device) and QoS flow 3 (the video stream in the middle of the concert hall). However, at time T2, QoS flow 1 (the data flow generated by the piano device) requires QoS coordination or time synchronization with QoS flow 4 (the data flow generated by the musicians' performance) and QoS flow 5 (the video stream in the southeast of the concert hall). At time T3, QoS flow 1 (the data flow generated by the piano device, the upstream data flow) requires QoS coordination or time synchronization with QoS flow 6 (the video stream pushed by the server, the downstream data flow).

[0112] In this way, the network can map QoS flow1, QoS flow2, and QoS flow3 into one RB1; map QoS flow1, QoS flow4, and QoS flow5 into one RB2; and map QoS flow1 and QoS flow6 into one RB3. The network configures RB1, RB2, RB3, and related parameters to the terminal. Based on this, the RB switching methods include but are not limited to the following:

[0113] 1) Based on the different coordination requirements of the services, the terminal switches the RBs required for the QoS flow through MAC CE or DCI. That is, the terminal switches based on network control commands, such as MAC CE or DCI. When switching is required, the terminal sends a control command. For example, at time T2, a control command is sent to switch the UE from RB1 to RB2. At time T3, another control command is sent to switch the UE from RB2 to RB3.

[0114] 2) The UE obtains the coordination requirements of the uplink service from the application layer and autonomously switches the RBs required for the QoS flow. After each switch, the UE may inform the base station through the UCI and / or MAC CE (e.g., Buffer Status Report (BSR)), or the UE may not inform the base station. This disclosure does not specifically limit this.

[0115] 3) The UE or base station obtains the coordination requirements between uplink and downlink services from the core network or application server, and switches the RBs required for the QoS flow through MAC CE or DCI each time a switch is required.

[0116] 4) Based on the different coordination requirements of the services, the network informs the UE of the RBs that the QoS flow needs to use at different times through signaling (e.g., a list of RB information and corresponding time information; or a bitmap and corresponding time information in the form of each bit position corresponding to an RB; or a bitmap and corresponding RB in the form of each bit position corresponding to a time; or a periodic list of RB information and corresponding time information based on the coordination characteristics of the services). The UE switches the RBs that the QoS flow needs to use according to this information.

[0117] 5) The UE obtains the coordination requirements of the uplink service from the application layer, and autonomously switches the RBs required for the QoS flow according to the service requirements; after the switch, the UE may inform the base station of the RBs required for the QoS flow at different times through signaling, or may not inform the base station, and this disclosure does not make specific restrictions on this.

[0118] 6) The UE or base station obtains the coordination requirements between uplink and downlink services from the core network or application server, determines the RBs to be used at multiple times based on the service requirements, and switches the RBs to be used by the QoS flow through signaling.

[0119] Alternatively: the network can map QoS flow1, QoS flow2, QoS flow3, QoS flow4, QoS flow5 and QoS flow6 into RB1, RB2, RB3, RB4, RB5 and RB6 respectively; and configure the RBs and related parameters to the terminal, and the UE or base station obtains the coordination requirements between uplink and downlink services from the core network or application server, determines the RBs to be used at different times based on the coordination requirements, and switches the RBs to be used by the QoS flow at different times through MAC CE or DCI, wherein the UE can be informed of the RBs to be switched at multiple times or the UE can be informed to switch when switching is required. Switching can also be performed through signaling or UE autonomous switching, etc., which is not specifically limited in this disclosure.

[0120] Alternatively, the network can map QoS flow1, QoS flow2, and QoS flow3 to RB1, RB2, and RB3 respectively; map QoS flow1, QoS flow4, and QoS flow5 to RB1, RB4, and RB5; and map QoS flow1 and QoS flow6 to RB1 and RB6; and configure the RBs and related parameters to the terminal; and define the association relationship between the logical channels corresponding to the corresponding RBs and the binding relationship between the CGs corresponding to the RBs according to the coordination requirements between different QoS flows. The details are as follows:

[0121] A. LC1, LC2, and LC3 corresponding to RB1, RB2, and RB3 are configured in association with relationship 1;

[0122] B. Configuration association relationship 2 of LC1, LC4, and LC5 corresponding to RB1, RB4, and RB5;

[0123] C. LC1 and LC6 corresponding to RB1 and RB6 are configured in association relationship 3;

[0124] D. RB1, RB2, RB3 corresponding to CG1, CG2, CG3 configuration association relationship 11;

[0125] E. RB1, RB4, RB5 corresponding to CG1, CG4, CG5 configuration association relationship 12;

[0126] F, RB1, RB6 corresponding to CG1, CG6 configuration association relationship 13;

[0127] Based on this, methods for implementing RB switching include but are not limited to the following:

[0128] 7) The network switches the association relationship between the logical channels corresponding to the RBs and / or the binding relationship between the CGs corresponding to the RBs through MAC CE or DCI according to the different coordination requirements of the services. For example, it switches between association relationships 1, 2, and 3 and / or between association relationships 11, 12, and 13.

[0129] 8) The UE obtains the coordination requirements of the uplink service from the application layer, and autonomously switches the association relationship between the logical channels corresponding to the RBs and / or the binding relationship between the CGs corresponding to the RBs. For example, it switches between association relationships 1, 2, and 3 and / or between association relationships 11, 12, and 13.

[0130] 9) The UE or base station obtains the coordination requirements between uplink and downlink services from the core network or application server, and switches the association relationship between the logical channels corresponding to the RBs and / or the binding relationship between the CGs corresponding to the RBs through MAC CE or DCI, for example, switching between association relationships 1, 2, and 3 and / or switching between association relationships 11, 12, and 13.

[0131] Furthermore, the UE may obtain multiple time-corresponding associations that require switching at a time, or obtain the association corresponding to the time when switching is required, thereby implementing the switching of the associations. This disclosure does not specifically limit this. Furthermore, the network may inform the UE of the associations at different times via signaling, and the UE may perform the switching based on the associations. Furthermore, after the UE autonomously switches, the switching result may be notified to the base station or not be notified to the base station. This disclosure does not specifically limit this.

[0132] Furthermore, for the same QoS flow, RB1 can be established for data requiring PDU management, and RB2 can be established for data requiring PDU set management. Based on the needs of upper-layer applications, RB1 can be switched when PDU management is required, and RB2 can be switched when PDU set management is required. Alternatively, for mobile XR devices or mobile base stations, switching can be performed based on whether the base station / UPF supports PDU set management when the QoS flow switches between different base stations / UPFs.

[0133] Furthermore, RB switching can also be performed based on at least one of the following situations: switching on different channel environments; switching based on QoE feedback; switching based on different signal source strategies selected by XR; switching between NTN and TN; switching between whether the aircraft in the air uses Air To Ground (ATG) base station services or satellite services; switching between satellites in different orbits; switching between plugged in and unplugged; switching under different power conditions; switching under different coverage conditions of the cell; switching under the condition that the base station activates the telepathy function; during the cell switching process, some cells support the PDU SET function, some cells do not support it, and only support the PDU function, and the corresponding QoS parameters are different. In this case, switching is performed; switching is performed when the UE sends a service in the RRC state or the UE sends a service in the RRC inactive state.

[0134] In the technical solution of the embodiment of the present disclosure, the network obtains first information, where the first information may be business requirements, etc., and then allocates multiple RBs to a QoS flow of the terminal, and issues rules for switching between different RBs, where the switching rules can determine corresponding switching rules based on business requirements, such as switching according to different times or other event triggers. The terminal switches different RBs according to the definition in the rules and informs the network through UCI, MAC CE or Packet Data Convergence Protocol Control Element (PDCP CE). In this way, dynamic switching of RBs in multiple modes can be achieved based on business requirements to meet more business needs.

[0135] FIG4 is a second flow diagram of a bearer management method provided by an embodiment of the present disclosure, which is applied to a network side (or a network device). As shown in FIG4 , the bearer management method includes the following steps:

[0136] Step 401: A network device sends and / or receives data of P1 flows, where P1 is an integer greater than 0, and the P1 flows are associated with each other.

[0137] In some implementations, the associated P1 flows have at least one of the following definitions:

[0138] When the flow is a QoS flow, P1 associated QoS flows form a Service Progress. This allows for more efficient management of the P1 associated flows. A Service Progress in this article may also be called a QoS flow set or a virtual QoS flow.

[0139] When the flow is a QoS flow, P1 QoS flows with an associated relationship are respectively mapped into N RBs, where N is an integer greater than 0.

[0140] When the flow is a QoS flow, the P1 QoS flows with an associated relationship are mapped into a super RB (S-RB). In conventional technology, multiple QoS flows mapped to one RB are required to have the same QFI and are not required to have an associated relationship.

[0141] When the flow is a QoS flow, a service process consisting of P1 associated QoS flows is mapped into a super RB; the difference from the previous one is that what the RAN side and the core network interface see is the service process, not the QoS flow.

[0142] When the flow is a radio bearer RB, the associated P1 RBs are mapped into a super RB (S-RB). Unlike the previous method, where merging occurs in the core network, this method performs the association or merging at the RAN PDCP / RLC layer. This allows for more efficient processing of data from associated flows with different QFIs, importance levels, or priorities. Data cannot be sorted or time-aligned within different RBs.

[0143] The super RB (S-RB) in this article can also be called an RB set, a virtual RB, etc., or it can still be called an RB.

[0144] The super logical channel (S-LC) in this article can also be called an LC set or a virtual LC, or it can still be called an LC.

[0145] When the flow is a logical channel (LC), the associated P1 LCs are mapped into a super logical channel (S-LC). The difference from the previous example is that the previous example performs the merging process in the core network, while the association process or merging process is performed in the RLC / MAC layer of the RAN.

[0146] When the flow is a PDU set packet, P1 PDU sets with an associated relationship are mapped into a super PDU set packet (Super Protocol Data Unit, S-PDU Set); the difference from the previous one is that more consideration is given to the association relationship between data belonging to the same application layer characteristics, for example, a PDU set is a type of frame.

[0147] Step 402: The network device processes the data of the P1 streams according to the definition using at least one of a service process, RB, super RB, LC, super LC, PDU aggregate package, and super PDU aggregate package and / or the network device configures the definition to the terminal.

[0148] In some implementations, for the case where the associated P1 QoS flows are respectively mapped to N RBs, the method further includes:

[0149] The network device switches the N RBs to M RBs and / or the network device instructs the terminal to switch the N RBs to M RBs, N and M are different or the same positive integers, P1 streams with an associated relationship are mapped to the N RBs, and P2 streams with an associated relationship are mapped to the M RBs; wherein:

[0150] The N RBs are different from the M RBs in at least one RB; and / or,

[0151] At least one of the P1 streams and the P2 streams is different, or the P1 stream and the P2 stream are the same, and P1 and P2 are different or the same positive integers; and / or,

[0152] The N RBs correspond to at least one of an L1 logical channel, an L2 CG / SPS configuration, and an L5 DRX configuration, where L1, L2, and L5 are different or identical positive integers. The M RBs correspond to at least one of an L3 logical channel, an L4 CG / SPS configuration, and an L6 DRX configuration, where L3, L4, and L6 are different or identical positive integers. These configurations correspond to the associations and QoS characteristics of different flows within each super RB.

[0153] In some embodiments, for the case where the associated P1 QoS flows are mapped to a super RB, or the service process is mapped to a super RB, or the associated P1 RBs are mapped to a super RB, the method further includes:

[0154] The network device switches the first super RB to the second super RB and / or the network device instructs the terminal to switch the first super RB to the second super RB, the first super RB is formed by N RBs, the second super RB is formed by M RBs, and N and M are different or the same positive integers; wherein: P1 flows with an associated relationship are mapped to the first super RB, and P2 flows with an associated relationship are mapped to the second super RB; or, the first service process is mapped to the first super RB, and the second service process is mapped to the second super RB; or, P1 RBs with an associated relationship are projected onto the first super RB, and P2 RBs with an associated relationship are projected onto the second super RB; P1 and P2 are different or the same positive integers.

[0155] In some embodiments, the super RB satisfies at least one of the following:

[0156] Prioritize uplink authorization to data in the same super RB; prioritize uplink authorization to data that arrives early in the same super RB and has the highest importance parameter level; prioritize uplink authorization to multiple data in the super RB whose QoS collaborative characterization QoS parameter values ​​are the same, or whose QoS parameter difference is less than or equal to a set threshold; wherein the QoS parameters include data with the highest importance parameter level in at least one of packet error rate, delay, jitter, data arrival time, synchronization accuracy, and reliability; prioritize uplink authorization to data in the super RB that has integrity requirements and / or multi-stream collaborative processing requirements with one or more packets that have been successfully processed; prioritize uplink authorization to data that arrives early in the super RB and has the highest quality requirement in layer parameters; prioritize uplink authorization to data in the super RB that has the highest quality requirement in layer parameters or whose difference between data cache delay and PDB is less than or equal to a set threshold ; Give priority to different or the same logical channels in the same super RB; Give priority to the logical channel corresponding to the data that arrives early and has the highest importance parameter level in a super RB; Give priority to the logical channel corresponding to multiple data in a super RB whose QoS collaborative characterization QoS parameters have the same value, or the difference in QoS parameters is less than or equal to the set threshold; wherein the QoS parameters include the data with the highest importance parameter level in at least one of the following: packet error rate, delay, jitter, data arrival time, synchronization accuracy, and reliability; Give priority to the logical channel corresponding to the data in a super RB that has integrity requirements and / or multi-stream collaborative processing requirements for one or more packets that have been successfully processed; Give priority to the data that arrives early in a super RB and has the highest quality requirements in the layer parameters; Give priority to the data in a super RB that has the highest quality requirements in the layer parameters or the difference between the data cache delay and the PDB is less than or equal to the set threshold.

[0157] In some embodiments, the super RB corresponds to at least one of the following configurations: L1 logical channels, L2 CG / SPS configurations, and L5 DRX configurations, where L1, L2, and L5 are different or identical positive integers. These configurations correspond to the associations and QoS characteristics of different flows in each super RB.

[0158] In some implementations, the data of the one super RB satisfies at least one of the following:

[0159] Use the same and / or adjacent transport blocks TB; use the transmission resources indicated by the same and / or adjacent uplink grants UL Grant; select the same LC or super LC.

[0160] In some embodiments, the association relationship includes at least one of the following:

[0162] In some embodiments, the method further comprises:

[0170] In some implementations, the QFI values ​​of the P1 flows are the same or different.

[0172] It should be noted that a service progress can also be called a QoS flow set or a virtual QoS flow. A super RB (S-RB) can also be called an RB set or a virtual RB.
