Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0116] Generally, RAN-assisted codec adaptation provides a method for an access network device (e.g., gNB) to send a recommended bit rate to a terminal (e.g., UE) to help the terminal select or adapt the codec bit rate for multimedia telephony (MMTEL) voice or video. The RAN-assisted codec adaptation mechanism supports uplink / downlink bit rate increase or decrease.

[0117] To adapt the uplink or downlink bit rate, the access network device can send a recommended bit rate to the terminal to inform the terminal of the current recommended uplink (UL) and / or downlink (DL) transmission bit rate. The terminal can adjust the bit rate based on the recommended bit rate and other information. For example, the terminal can send a bit rate request to the peer through an application layer message, so that the peer can adjust the codec bit rate through the request in combination with other information.

[0118] Optionally, the access network device can send the recommended UL and DL bit rates to the terminal through a medium access control (MAC Control Element, MAC) control element (MAC CE).

[0119] Optionally, based on the recommended bit rate sent by the access network device, the terminal can start bit rate adaptation with the peer (e.g., terminal). For example, the access network device #1 first sends an uplink recommended bit rate to the terminal #1, and then the terminal #1 sends the recommended bit rate to the terminal #2 through an application layer message (e.g., through a real-time transport protocol (RTP) message), and the terminal #2 can send a recommended bit rate query message to its corresponding access network device (e.g., access network device #2), and then the access network device #2 can send its recommended bit rate to the terminal #2.

[0120] Optionally, the access network device #2 can send its recommended bit rate to the terminal #2, which can be the same as or different from the recommended bit rate in the recommended bit rate query message sent by the terminal #2 to the access network device #2.

[0121] Optionally, the terminal can send a recommended bit rate query message to the access network device through a MAC CE.

[0122] In Multi-Radio Dual Connectivity (MR-DC), or simply DC, a UE with multiple receive (Rx) and / or transmit (TX) channels can be configured to connect to two different network nodes over a non-ideal backhaul and utilize the resources provided by the two different network nodes. One of the nodes provides New Radio (NR) access and the other node provides Evolved Universal Terrestrial Radio Access (E-UTRA) or NR access. One node acts as a Master Node (MN) and the other as a Secondary Node (SN). The MN and SN are connected through a network interface, and at least the MN is connected to the core network.

[0123] In MR-DC, from the perspective of the UE, there are three types of bearers: Master Cell Group (MCG) bearers, Secondary Cell Group (SCG) bearers, and split bearers. Among them, the split bearer allows data to be split during transmission and transmitted through different access network devices, thereby achieving load sharing and optimizing data traffic.

[0124] From the perspective of the network, each bearer (MCG bearer, SCG bearer, and split bearer) can be terminated in the MN or the SN.

[0125] Optionally, the 3rd Generation Partnership Project (3GPP) introduces a number of enhancements for eXtended Reality (XR) services, such as rate control for XR traffic to quickly adapt to congestion conditions on the uplink.

[0126] Optionally, after the access layer of the terminal receives the recommended bit rate sent by the access network device, the high layer is instructed about the recommended bit rate of the corresponding logical channel and direction (such as uplink or downlink).

[0127] For a terminal configured with dual connectivity, in the case that the split bearer corresponds to different access network devices, and different access network devices indicate recommended bit rates for the split bearer, it is necessary to determine the recommended bit rate finally used by the split bearer.

[0128] The method for determining the rate provided by the embodiments of the present disclosure is based on the two recommended bit rates respectively indicated by the MN and the SN, and the terminal and the network device determine the final recommended bit rate corresponding to the split bearer, thereby ensuring the consistency of the understanding of the recommended bit rate corresponding to the split bearer by the terminal and the network device, providing conditions for improving the utilization rate of wireless resources, and improving the reliability of split bearer transmission.

[0129] In the disclosure, the recommended bit rate is used to indicate the recommendation of the transmission rate control of the terminal by the access network device. The scheme provided by the embodiments of the present disclosure is not only applicable to the Recommended Bit Rate MAC CE defined in LTE and NR, but also applicable to other rate control signaling sent by the access network device. For example, it can be applicable to the adjustment of the recommended bit rate in RAN-assisted codec adaptation, and can be applicable to the rate control of XR service.

[0130] FIG. 2A is an interaction schematic diagram of a method for determining a rate according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiments of the present disclosure relate to a method for determining a rate, which can be used in the communication system 100, and the above method comprises:

[0131] In step S2101, the first network device sends a second recommended bit rate of a split bearer to an access layer of the first terminal.

[0132] In some embodiments, the first network device can be an access network device.

[0133] In some embodiments, the first network device can be a master node (MN) or a secondary node (SN).

[0134] In some embodiments, the master node can be used to be responsible for processing a signaling bearer between the terminal and the core network.

[0135] In some embodiments, the technical terms such as “master node”, “master access network device”, “master base station” and the like can be replaced with each other in some scenarios.

[0136] In some embodiments, the secondary node can be used to provide a data bearer for the terminal.

[0137] In some embodiments, the technical terms such as “secondary node”, “secondary access network device”, “secondary base station” and the like can be replaced with each other in some scenarios.

[0138] In some embodiments, the access layer (Access Stratum, AS) of the first terminal is used to implement the communication between the first terminal and the network device.

[0139] In some embodiments, the access layer can be any one of a MAC layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, and a Radio Resource Control (RRC) layer.

[0140] In some embodiments, the second network device can further send the first recommended bit rate to the first network device, and then the first network device sends the first recommended bit rate to the access layer of the first terminal.

[0141] In step S2102, the second network device sends the third recommended bit rate of the split bearer to the access layer of the first terminal.

[0142] In some embodiments, the second network device can be an access network device.

[0143] In some embodiments, the second network device can be an SN or an MN.

[0144] In some embodiments, the third recommended bit rate can be the same as or different from the second recommended bit rate.

[0145] In some embodiments, the above steps S2101 and S2102 can be performed simultaneously or S2102 can be performed first and then S2101, and the present disclosure does not limit this.

[0146] In some embodiments, the second network device can further send the first recommended bit rate to the first network device, and then the first network device sends the first recommended bit rate to the access layer of the first terminal.

[0147] In step S2103, the first network device sends the preset rule to the first terminal.

[0148] In some embodiments, the first network device sends the preset rule to the access layer of the first terminal.

[0149] In some embodiments, the preset rule is used to assist the terminal in determining the final first recommended bit rate of the split bearer based on the second recommended bit rate and the third recommended bit rate.

[0150] In some embodiments, the preset rule can be that the sum of the second recommended bit rate and the third recommended bit rate is determined as the first recommended bit rate. For example, the second recommended bit rate is R M , the third recommended bit rate is R S , and the first recommended bit rate can be determined as R M + R S .

[0151] In the embodiments of the present disclosure, the preset rule indicates that the first recommended bit rate corresponding to the split bearer is the sum of the two recommended bit rates respectively indicated by the first network device and the second network device, so that the terminal can directly communicate with the network device using the channel corresponding to the split bearer based on the recommended bit rate indicated by each network device.

[0152] In some embodiments, the preset rule can be to determine the second recommended bit rate as the first recommended bit rate. For example, the second recommended bit rate is R M , the first recommended bit rate can be determined as R M .

[0153] In the embodiments of the present disclosure, the preset rule indicates that the first recommended bit rate corresponding to the split bearer is the second recommended bit rate indicated by the first network device, thereby reducing the amount of data respectively transmitted by the first network device and the second network device in the split bearer scenario, and greatly ensuring the reliability of the split bearer transmission.

[0154] In some embodiments, the preset rule can be to determine the third recommended bit rate as the first recommended bit rate. For example, the third recommended bit rate is R N , the first recommended bit rate can be determined as R S .

[0155] In the embodiments of the present disclosure, the preset rule indicates that the first recommended bit rate corresponding to the split bearer is the third recommended bit rate indicated by the second network device, thereby reducing the amount of data respectively transmitted by the first network device and the second network device in the split bearer scenario, and greatly ensuring the reliability of the split bearer transmission.

[0156] In some embodiments, the preset rule can be to determine the larger value of the second recommended bit rate and the third recommended bit rate as the first recommended bit rate. For example, the second recommended bit rate is R M , and the third recommended bit rate is R S， If R M > R S , the first recommended bit rate can be determined as R M , and otherwise, the first recommended bit rate is determined as R S .

[0157] In the embodiments of the present disclosure, the preset rule indicates that the first recommended bit rate corresponding to the split bearer is the larger value of the recommended bit rates respectively indicated by the first network device and the second network device, thereby reducing the amount of data respectively transmitted by the first network device and the second network device in the split bearer scenario, and maximizing the amount of data transmitted by the split bearer.

[0158] In some embodiments, the preset rule can be to determine the first recommended bit rate as the smaller one of the second recommended bit rate and the third recommended bit rate. For example, the second recommended bit rate is R M , the third recommended bit rate is R S , and if R M >R S , the first recommended bit rate can be determined as R S , and otherwise, the first recommended bit rate can be determined as R M .

[0159] In the embodiments of the present disclosure, the preset rule indicates that the first recommended bit rate corresponding to the split bearer is the smaller one of the recommended bit rates respectively indicated by the first network device and the second network device, so that the data amount respectively transmitted by the first network device and the second network device is reduced in the split bearer scenario, and the reliability of the split bearer is maximally guaranteed. In some embodiments, the first network device can send the second recommended bit rate and the preset rule to the first terminal by using the same message.

[0160] In some embodiments, the step S2103 can be performed synchronously with S2101 and S2102, or before S2101, or before S2102, and the like, which are not limited in the present disclosure.

[0161] In some embodiments, the first terminal can determine the preset rule according to the protocol agreement, that is, the step S2103 can be omitted.

[0162] In some embodiments, the granularity of the preset rule can be determined as needed. For example, the preset rule can be associated with the terminal, that is, the preset rule received by the first terminal is only applicable to the first terminal.

[0163] In some embodiments, the preset rule can also be associated with a MAC entity identifier. For example, the preset rule received by the first terminal can include a rule associated with an MN MAC entity identifier and a rule associated with an SN MAC entity identifier. Thus, for different MAC entities, the first terminal can determine the recommended bit rate finally used by the split bearer based on the associated rule.

[0164] In some embodiments, the preset rule can also be associated with a data radio bearer (DRB) identifier. The preset rules associated with different DRB identifiers can be the same or different.

[0165] In step S2104, the access layer of the first terminal determines the first recommended bit rate according to at least one of the second recommended bit rate and the third recommended bit rate according to the preset rule.

[0166] For example, suppose a certain separate bearer DRB#1 corresponds to the logical channel LCH in the first network device. M The logical channel corresponding to the secondary node is LCH. S .

[0167] Taking the sum of the second and third recommended bit rates as the first recommended bit rate, according to preset rules, as an example, if the access layer of the first terminal first receives the logical channel LCH sent by the first network device... M The recommended uplink bit rate is R M Then the access layer of the first terminal can indicate to the higher layers the recommended uplink bit rate of the separated bearer DRB#1 to R. M Then, upon receiving a message from the second network device for logical channel LCH... S Recommended uplink bit rate R S Then the access layer of the first terminal can indicate to the higher layers the recommended uplink bit rate of the separated bearer DRB#1 to R. M +R S .

[0168] Taking the larger of the second and third recommended bit rates as the first recommended bit rate, according to preset rules, if the access layer of the first terminal first receives the logical channel LCH sent by the first network device... M The recommended uplink bit rate is R M Then the access layer of the first terminal can indicate to the higher layers the recommended uplink bit rate of the separated bearer DRB#1 to R. M If subsequently received from a second network device for logical channel LCH S The recommended uplink bit rate is R S , . Then when R M <R S At that time, the access layer of the first terminal can indicate to the higher layer the recommended uplink bit rate of the separated bearer DRB#1 to R. S Otherwise, the access layer of the first terminal may not indicate the new recommended bit rate to the higher layers.

[0169] For example, suppose there is a separate bearer DRB#2. The preset rule is to determine the first recommended bit rate as the sum of the second recommended bit rate and the third recommended bit rate. If the access layer of the first terminal first receives an uplink recommended bit rate of R from the first network device... M Then the access layer of the first terminal can indicate to the higher layers the recommended uplink bit rate of the separated bearer DRB#1 to R. M Then, the access layer of the first terminal receives the uplink recommended bit rate R sent by the second network device. SIf the access layer of the first terminal receives the uplink recommended bit rate of R for the QFI#1 from the second network device, the access layer of the first terminal can indicate to the higher layer that the uplink recommended bit rate of the QFI#1 is R M + R S .

[0170] For example, assume a split bearer DRB#2. The QoS flow identifier of the bearer is QFI#1. The first recommended bit rate is determined as the sum of the second recommended bit rate and the third recommended bit rate according to the preset rule. If the access layer of the first terminal first receives the uplink recommended bit rate of R for the QFI#1 from the first network device, the first terminal can indicate to the higher layer that the uplink recommended bit rate of the QFI#1 is R M . M If the access layer of the first terminal receives the uplink recommended bit rate of R for the QFI#1 from the second network device, the access layer of the first terminal can indicate to the higher layer that the uplink recommended bit rate of the QFI#1 is R S . M + R S .

[0171] In step S2105, the access layer of the first terminal sends the first split bearer information to the higher layer.

[0172] In some embodiments, the first recommended bit rate is included in the first split bearer information.

[0173] In some embodiments, the higher layer of the first terminal can be responsible for completing a series of tasks related to business logic, network interaction and data processing.

[0174] In some embodiments, the higher layer of the first terminal can be an application layer, a Real-time Transport Protocol (RTP) layer, etc.

[0175] In some embodiments, the first split bearer information can further include a transmission direction corresponding to the first recommended bit rate, such as uplink or downlink.

[0176] In some embodiments, the first split bearer information can further include a logical channel (LCH) identifier for indicating a logical channel to which the first recommended bit rate is applicable.

[0177] In some embodiments, the first split bearer information can further include a data radio bearer (DRB) identifier for indicating a DRB to which the first recommended bit rate is applicable. For example, if the first split bearer information includes DRB#1 and the first recommended bit rate, the higher layer of the first terminal can determine that the recommended bit rate of the DRB#1 is the first recommended bit rate.

[0178] In some embodiments, the first separation bearer information further comprises a Quality of Service (QoS) Flow identification (QFI), which is used to indicate the QFI to which the first recommended bit rate is applicable.

[0179] In some embodiments, the access layer of the first terminal further sends the first recommended bit rate to the first network device. Then the first network device sends the first recommended bit rate to the second network device. In this way, the understanding of the recommended bit rate used by the first terminal, the first network device and the second network device for the separation bearer is consistent, and the reliability of the separation bearer is improved.

[0180] In some embodiments, the access layer of the first terminal further sends the first recommended bit rate to the second network device. Then the second network device sends the first recommended bit rate to the first network device. In this way, the understanding of the recommended bit rate used by the first terminal, the first network device and the second network device for the separation bearer is consistent, and the reliability of the separation bearer is improved.

[0181] In some embodiments, the access layer of the first terminal further sends the first recommended bit rate to the first network device and the second network device respectively. In this way, the understanding of the recommended bit rate used by the first terminal, the first network device and the second network device for the separation bearer is consistent, and the reliability of the separation bearer is improved.

[0182] In step S2106, the first terminal sends the first recommended bit rate to the second terminal.

[0183] In some embodiments, the high layer of the first terminal sends the first recommended bit rate to the second terminal.

[0184] In some embodiments, the second terminal can send a recommended bit rate negotiation message to the network device accessed by the second terminal to negotiate the final recommended bit rate, which is not limited in the present disclosure.

[0185] The method for determining the rate related in the embodiments of the present disclosure can comprise at least one of steps S2101-S2106. For example, step S2103 can be implemented as an independent embodiment, step S2104 can be implemented as an independent embodiment, steps S2103+S2104 can be implemented as an independent embodiment, steps S2101+S2102+S2103+S2104 can be implemented as an independent embodiment, steps S2103+S2104+S2105+S2106 can be implemented as an independent embodiment, and the like.

[0186] In the embodiments or examples, each step can be independent, arbitrarily combined or exchanged in sequence, and optional modes or examples can be arbitrarily combined, without contradiction, and can be arbitrarily combined with any step of other embodiments or other examples.

[0187] In the embodiments of the present disclosure, after receiving the second recommended bit rate and the third recommended bit rate respectively sent by different network devices, the access layer of the terminal determines the final first recommended bit rate of the split bearer based on the preset rule, and then synchronizes the first recommended bit rate to the high layer and the network device respectively, thereby ensuring the consistency of the understanding of the recommended bit rate of the split bearer by the terminal and the network node, providing conditions for avoiding waste of wireless resources, and minimizing the amount of data transmitted between the access layer and the high layer of the terminal, and saving the power consumption of the terminal.

[0208] In step S2301, the first network device receives one recommended bit rate of the split bearer of the first terminal sent by the second network device.

[0209] In some embodiments, the first network device can be the MN or the SN, and the corresponding second network device can be the SN or the MN.

[0210] In some embodiments, the first network device is the MN, and the second network device is the SN. In this case, the recommended bit rate sent by the second network device to the first network device is the third recommended bit rate.

[0304] Figure 5 is an interaction diagram of a method for determining a rate according to yet another embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a method for determining a rate, which can be used in a communication system. The communication system includes a first terminal and a network device, and the method includes:

[0305] In step S5101, a first recommended bit rate of the split bearer is determined, wherein the first recommended bit rate is determined based on at least one of a second recommended bit rate indicated by the master node MN and a third recommended bit rate indicated by the secondary node SN.

[0306] The specific implementation of step S5101 can refer to the detailed description of any of the above embodiments, which will not be described here.

[0307] The following exemplary describes the above method by taking the first network device as the MN and the second network device as the SN.

[0308] Scheme one: the terminal's AS layer (which can be MAC, RLC, PDCP, RRC, etc.) obtains the final recommended bit rate according to certain rules and indicates it to the upper layer, that is, the AS determines the final rate and provides it to the upper layer. For the upper layer, the final recommended bit rate of the split bearer can be directly obtained. These rules include but are not limited to:

[0309] a) the final recommended bit rate is the sum of the recommended bit rate sent by the MN and the recommended bit rate sent by the SN;

[0310] b) the final recommended bit rate is the recommended bit rate sent by the MN;

[0311] c) the final recommended bit rate is the recommended bit rate sent by the SN;

[0312] d) the final recommended bit rate is the larger one of the recommended bit rates sent by the MN and the SN;

[0313] e) the final recommended bit rate is the smaller one of the recommended bit rates sent by the MN and the SN.

[0314] The terminal obtains the final recommended bit rate according to the recommended bit rates of the split bearer sent by different access network devices according to the above rules, and indicates it to the upper layer according to whether it changes.

[0315] Taking rule a) as an example. If the recommended bit rate sent by the master node is R M , the terminal can indicate this bit rate to the upper layer. If the recommended bit rate sent by the secondary node is R S later, the terminal indicates R M + R S to the upper layer.

[0316] These rules can be specified by standards or configured by the network, e.g. through RRC signaling. The granularity of the configuration can be UE, MAC entity, or DRB.

[0317] For example, assume a split bearer DRB x , the logical channel corresponding to the master node is LCH M , and the logical channel corresponding to the secondary node is LCH S .

[0318] Take rule a) as an example. The uplink recommended bit rate for the logical channel LCH M sent by the master node is R M . The terminal can indicate to the higher layer that the uplink recommended bit rate for the split bearer DRB x is R M . If the uplink recommended bit rate for the logical channel LCH S sent by the secondary node is R S , the terminal indicates to the higher layer that the uplink recommended bit rate for the split bearer DRB x is R M + R S .

[0319] Take rule d) as an example. The uplink recommended bit rate for the logical channel LCH M sent by the master node is R M . The terminal can indicate to the higher layer that the uplink recommended bit rate for the split bearer DRB x is R M . If the uplink recommended bit rate for the logical channel LCH S sent by the secondary node is R S , when R M < R S , the terminal indicates to the higher layer that the uplink recommended bit rate for the split bearer DRB x is R S ; otherwise, the terminal does not indicate the relevant recommended bit rate information to the higher layer.

[0320] For example, assume a split bearer DRB x . Take rule a) as an example. The uplink recommended bit rate for the DRB x sent by the master node is R M . The terminal can indicate to the higher layer that the uplink recommended bit rate for the split bearer DRB x is R M . If the uplink recommended bit rate for the DRB x sent by the secondary node is R SIf the uplink recommended bit rate of the DRB is R x , the terminal indicates to the higher layer that the uplink recommended bit rate of the DRB is R M + R S .

[0321] For example, assume that the DRB is a split bearer x , and the identity of the QoS flow of the bearer is QFI y . Take rule a) as an example. If the uplink recommended bit rate of QFI y recommended by the master node is R M , the terminal can indicate to the higher layer that the uplink recommended bit rate of QFI y is R M . If the uplink recommended bit rate of QFI y recommended by the secondary node is R S later, the terminal indicates to the higher layer that the uplink recommended bit rate of QFI y is R M + R S .

[0322] Thus, by determining the final recommended bit rate of the split bearer by the AS layer of the terminal, and then indicating the final recommended bit rate to the higher layer, the understanding of the recommended bit rate of the split bearer by the terminal and the network node is consistent, which provides a condition for avoiding waste of radio resources, and reduces the amount of data transmitted between the access layer and the higher layer of the terminal as much as possible, and saves the power consumption of the terminal.

[0323] Scheme two: the AS of the terminal indicates to the higher layer the uplink and downlink directions and the recommended bit rate, and at least one of the logical channel, the DRB ID, or the QFI, and the node (the master node and / or the secondary node) that sends the recommended bit rate, for the recommended bit rate of the split bearer sent by the access network device. At this time, the higher layer can know whether the recommended bit rate is recommended by the master node or the secondary node or both. Then, the higher layer can obtain the final recommended bit rate for the split bearer according to certain rules based on the information sent by the AS. These rules include but are not limited to:

[0324] a) the final recommended bit rate is the sum of the recommended bit rate sent by the MN and the recommended bit rate sent by the SN;

[0325] b) the final recommended bit rate is the recommended bit rate sent by the MN;

[0326] c) the final recommended bit rate is the recommended bit rate sent by the SN;

[0327] d) the final recommended bit rate is the larger one of the recommended bit rate sent by the MN and the recommended bit rate sent by the SN;

[0328] e) the final recommended bit rate is the smaller one of the recommended bit rates sent by MN and SN.

[0329] The high layer obtains the final recommended bit rate according to the recommended bit rates of the split bearers sent from different access network devices, according to the above rules. Take rule a) as an example. If the recommended bit rate sent by the master node is R M , the AS indicates R M to the high layer, the high layer can indicate this bit rate to the opposite end. If the recommended bit rate sent by the secondary node is R S later, the AS indicates R S to the high layer, the high layer can indicate R M + R S to the opposite end.

[0330] Thus, by determining the final recommended bit rate of the split bearer by the high layer of the terminal, the consistency of the understanding of the recommended bit rate of the split bearer by the terminal and the network node is ensured, which provides the condition for avoiding the waste of wireless resources, and tries to ensure the accuracy and reliability of the final recommended bit rate of the split bearer obtained by the high layer of the terminal, which provides the condition for the reliable operation of the high layer service.

[0331] Scheme three: MN and SN coordinate the recommended bit rate of the split bearer through Xn signaling.

[0332] For example, only MN can inform the terminal of the recommended bit rate of the split bearer. SN can inform MN of the recommended bit rate of the split bearer. MN informs the terminal of the final recommended bit rate of the split bearer according to the recommended bit rate provided by itself for the split bearer and the recommended bit rate indicated by SN. Wherein, how MN determines the recommended bit rate of the split bearer can be realized based on the above rules. For example, adding the recommended bit rate provided by itself for the split bearer and the recommended bit rate indicated by SN, or determining the larger one of the two as the final recommended bit rate, or determining the smaller one of the two as the final recommended bit rate, etc.

[0333] For example, assume that a certain split bearer DRB x of a certain terminal UE x is LCH M corresponding to the logical channel of the master node, and LCH S corresponding to the logical channel of the secondary node. Only MN can inform the terminal of the recommended bit rate of the split bearer. SN can inform MN of the recommended bit rate of the uplink of the split bearer DRB x of the terminal UE x , which is R S . Assume that the recommended bit rate provided by MN itself for the uplink of the split bearer is R M , then MN can inform the terminal UE xa logical channel LCH M on a split bearer DRB x a recommended bit rate of uplink is R M +R S .

[0334] Thus, by determining the final recommended bit rate of the split bearer of the terminal by the network node, the consistency of the understanding of the recommended bit rate of the split bearer by the terminal and the network node is ensured, the condition for avoiding waste of wireless resources is provided, and the amount of data transmitted between the terminal and the network device is reduced, thereby providing the condition for saving the power consumption of the terminal.
