Description

Communication method and communication apparatus

[0001] This application claims priority to the Chinese Patent Application No. 202411096440.1, filed on August 9, 2024, entitled “Communication method and communication apparatus”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and more particularly, to a power adjustment method and a communication apparatus. BACKGROUND

[0003] With the emergence of applications such as extended reality (XR) and artificial intelligence (AI), human entertainment life has been greatly enriched. Due to the size limitation of terminal devices, the local computing power of terminal devices usually cannot provide high-quality picture calculation, and therefore the industry has proposed a network-assisted computing scheme. For example, for an XR terminal device, when the computing load of the XR terminal device is high, the XR terminal device can request the network to undertake part of the computing processing tasks of the XR terminal device, which can not only reduce the computing amount of the XR terminal device, but also allow the user to have a better service experience, such as higher-quality pictures and shorter latency.

[0004] However, in the scenario of network device switching, how to guarantee the continuity of computing processing of the service of the terminal device (including computing processing by the terminal device and auxiliary computing processing by the network) is a technical problem to be solved at present. SUMMARY

[0005] The present application provides a communication method and a communication apparatus, which can support guaranteeing the continuity of computing processing of the service of the terminal device.

[0006] In a first aspect, a communication method is provided, comprising: sending request information, the request information requesting a terminal apparatus to switch from a first network apparatus to a second network apparatus, the request information comprising first auxiliary computing information, the first auxiliary computing information indicating a proportion of auxiliary computing provided by the first network apparatus for a service of the terminal apparatus; receiving response information, the response information indicating that the terminal apparatus is allowed to switch from the first network apparatus to the second network apparatus, the response information comprising second auxiliary computing information, the second auxiliary computing information indicating a proportion of auxiliary computing provided by the second network apparatus for the service of the terminal apparatus; and sending indication information to the terminal apparatus, the indication information indicating that the terminal apparatus switches from the first network apparatus to the second network apparatus, the indication information comprising the second auxiliary computing information.

For ease of description, the first network device is taken as an example in the following description.

[0008] In the solution, the first network device obtains the information of the auxiliary calculation proportion provided by the second network device for the service of the terminal device through the response information sent by the second network device, and when it is determined that the terminal device is allowed to switch from the first network device to the second network device, the first network device sends the second auxiliary calculation information to the terminal device, and the terminal device adjusts the calculation processing proportion for the service according to the auxiliary calculation proportion indicated by the second auxiliary calculation information, such as adjusting from the first calculation processing proportion (corresponding to the auxiliary calculation proportion provided by the first network device) to the second calculation processing proportion (corresponding to the auxiliary calculation proportion provided by the second network device), thereby ensuring the continuity of the calculation processing of the service.

[0009] In some implementations of the first aspect, the method further includes: receiving a first data packet from a core network element; and sending a second data packet to the second network device, the second data packet being related to the first data packet. The first data packet is a data packet that is unsuccessfully transmitted between the core network element and the terminal device.

[0010] In this way, the first network device can send the data packet from the core network element to the second network device, which can reduce the data packet loss rate in the downlink data transmission scenario.

[0015] In some implementations of the first aspect, the method further includes: receiving a third data packet from the terminal device; and sending a fourth data packet to the second network device, the fourth data packet being related to the third data packet. The third data packet is a data packet that is unsuccessfully transmitted between the terminal device and the core network element.

[0016] In this way, the terminal device can send a data packet that is unsuccessfully transmitted between the terminal device and the core network element to the second network device through the first network device, which can reduce the data packet loss rate in the uplink data transmission scenario.

[0017] In some implementations of the first aspect, the fourth data packet is related to the third data packet, including at least one of: the fourth data packet is a data packet obtained by the first network device performing first auxiliary computation processing on the third data packet; or the fourth data packet is the third data packet.

[0019] In some implementations of the first aspect, the method further includes: sending second state information to the second network device, the second state information indicating a computation state of the fourth data packet, and the second state information being used by the second network device to determine a processing manner of the fourth data packet.

[0020] In this way, the second network device can complete the transmission processing of the fourth data packet according to the computation state of the fourth data packet.

[0021] In some implementations of the first aspect, the method further includes: receiving a fifth data packet from the second network device, the fifth data packet being a data packet obtained by the terminal device performing computation processing corresponding to the first auxiliary computation; and sending a sixth data packet to the second network device, the sixth data packet being a data packet obtained by the first network device performing first auxiliary computation processing on the fifth data packet.

[0022] When the terminal device switches from the first network device to the second network device, the first network device can process a data packet that is unsuccessfully transmitted between the terminal device and the core network element from the second network device, and send the processed data packet to the second network device, thereby reducing the data packet loss rate in the uplink data transmission scenario.

[0023] In some implementations of the first aspect, the request information further includes computation capability information of the terminal device, the computation capability information of the terminal device indicating a computation capability of the terminal device, and the computation capability information of the terminal device being related to the determination of the information of the second auxiliary computation.

[0027] In the above solution, the second network apparatus can send information about a proportion of auxiliary computing provided by the second network apparatus for a service of the terminal device to the first network apparatus, which can support ensuring the continuity of computing and processing the service of the terminal device. For example, when it is determined that the terminal device is allowed to switch from the first network apparatus to the second network apparatus, the first network apparatus can send information about a proportion of auxiliary computing provided by the second network apparatus for the service of the terminal device to the terminal device, and the terminal device can adjust a proportion of computing and processing the service of the terminal device according to the information about the proportion of auxiliary computing of the second network apparatus, such as adjusting from a first proportion of computing and processing (corresponding to a proportion of auxiliary computing provided by the first network apparatus) to a second proportion of computing and processing (corresponding to a proportion of auxiliary computing provided by the second network apparatus), thereby ensuring the continuity of computing and processing the service.

[0039] Thus, this can reduce the data packet loss rate in the uplink transmission scenario.

[0040] In some implementations of the second aspect, the sending the fourth data packet to the core network element according to the second status information comprises: the second status information indicates that the fourth data packet is a data packet processed by the first auxiliary computation, and the sending the fourth data packet to the core network element.

[0086] In order to facilitate understanding of the embodiments of the present application, the following points are first explained.

[0087] I. Unless otherwise specified, the meaning of "multiple" is two or more, and the meaning of "at least one" is one or more.

[0088] II. If there is no special description and logical conflict, the terms and / or descriptions of different embodiments of the present application are consistent and can be mutually referred to. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0089] Third, the various numbers in the present application only serve as a convenient distinction and do not serve to limit the scope of protection of the present application. The magnitude of the serial numbers in the present application does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic. For example, the terms "first", "second", "third", "fourth" and other various term labels in the specification and claims of the present application and the drawings (if any) are used to distinguish similar objects and do not necessarily describe a specific order or sequence. Among them, the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0090] At the same time, any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the use of "exemplary" or "for example" and the like is intended to present the relevant concept in a specific manner for ease of understanding.

[0091] Fourth, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0092] Fifth, in the present application, "for indicating" can be understood as "enabling", and "enabling" includes direct enabling and indirect enabling. When describing that a certain information is used to enable A, it can include that the information directly enables A or indirectly enables A, and it does not mean that A must be carried in the information.

[0093] The information enabled by the information is called to-be-enabled information, and there are many ways to enable the to-be-enabled information in the implementation process, for example, but not limited to, the to-be-enabled information can be directly enabled, such as the to-be-enabled information itself or the index of the to-be-enabled information. The to-be-enabled information can also be indirectly enabled by enabling other information, and there is an association relationship between the other information and the to-be-enabled information. The to-be-enabled information can also be enabled only for a part, and the other part of the to-be-enabled information is known or agreed in advance. For example, the enabling of a specific information can also be realized by means of the arrangement order of each information agreed in advance (such as a protocol), thereby reducing the enabling overhead to a certain extent. At the same time, the common part of each information can be identified and uniformly enabled to reduce the enabling overhead caused by enabling the same information separately.

In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed order of various information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information units, and the sending period and / or timing of these sub-information units can be the same or different.

[0096] VI. In this application, "pre-configuration" may include pre-defined terms, such as protocol definitions. These "pre-defined terms" can be implemented by pre-storing corresponding codes, tables, or other means of indicating relevant information in the device (e.g., including various network elements). This application does not limit the specific implementation method.

[0097] VII. The term "storage" or "preservation" in this application can refer to storage in one or more memory devices. These memory devices can be separately configured or integrated into an encoder, decoder, processor, or communication device. Alternatively, some memory devices can be separately configured, while others can be integrated into a decoder, processor, or communication device. The type of memory can be any form of storage medium, and this is not limited.

[0098] 8. The term "protocol" in this application may refer to standard protocols in the field of communications, for example, it may include fourth-generation (4G) protocols. th Generation 4G network, fifth generation (5G) network th This application does not limit the scope to network protocols such as generation (5G), NR, 5.5G, and related protocols applied in future communication networks.

[0101] Eleven, in this application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information is XX, which can include direct transmission through the air interface, or indirect transmission through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information is YY, which can include direct reception from YY through the air interface, or indirect reception from YY through the air interface by other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within devices through buses, wires or interfaces.

[0102] First, the communication system to which the embodiments of the present application are applicable is described.

[0103] FIG. 1 is a schematic diagram of a communication system 100 to which embodiments of the present application are applicable. As shown in FIG. 1, the communication system 100 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g., 110a and 110b, collectively referred to as 110) and at least one terminal device (e.g., 120a-120j, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1), etc. The terminal devices 120 are connected to the RAN nodes 110 in a wireless manner. The RAN nodes 110 are connected to the CN 200 in a wireless or wired manner. The core network devices in the CN 200 and the RAN nodes 110 in the RAN 100 can be different physical devices, respectively, or can be the same physical device integrated with the logical functions of the CN and the RAN.

[0104] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 4G, 5G communication system or a future communication system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (C-RAN or CRAN), a wireless fidelity (Wi-Fi) system. The RAN 100 can also be a communication system in which two or more of the above systems are fused.

[0105] The RAN node 110, which can also be referred to as an access network device, a RAN entity, or an access node, etc., is configured to help terminal devices to access the network wirelessly. The RAN nodes 110 in the communication system 100 can be of the same type or of different types. In some scenarios, the roles of the RAN node 110 and the terminal device 120 are relative, e.g., the network element 120i can be a helicopter or a drone, which can be configured to be a mobile base station. For a terminal device 120j accessing the RAN 100 via the network element 120i, the network element 120i is a base station. But for the base station 110a, the network element 120i is a terminal device. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b can be understood as communication apparatuses with base station functionalities, and the network elements 120a-120j can be understood as communication apparatuses with terminal functionalities.

[0106] In a possible scenario, the RAN node can be a base station (BS), an evolved NodeB (eNB), an access point (AP), a transmission point (TP), a transmission reception point (TRP), a next generation NodeB (gNB), a future communication network node, or an access node in a Wi-Fi system, etc. The RAN node can be a macro base station (e.g., 110a in FIG. 1), a micro base station or an indoor station (e.g., 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario.

[0107] The RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform, such as a cloud platform. The RAN node in this application can also be a logical node, a logical module or software that can realize all or part of the functions of the RAN node.

[0108] In another possible scenario, multiple RAN nodes cooperate to assist terminal devices to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0109] In different communication systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the sake of convenience, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0113] In embodiments of the present application, the terminal device can also be a device with communication function in a future communication network, without limitation to the form or type of the terminal device in the future communication network, etc.

[0114] In the embodiments of the present application, the communication apparatus for implementing the function of the terminal device can be a terminal device, or an apparatus capable of supporting the terminal device to implement the function, such as a chip system. The apparatus can be installed in the terminal device or used in matching with the terminal device. In the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.

[0115] In the embodiments of the present application, the network device is a device with wireless transceiving function, used for communicating with the terminal device. The network device can be a node in the RAN, also can be called a base station, and also can be called a RAN node, which can be an eNB of long term evolution (LTE), or a base station of 5G network such as gNB, or a base station in a public land mobile network (PLMN) evolved after 5G, a broadband network gateway (BNG), a convergence switch, or a network device in the 3GPP, etc.

[0117] In the embodiments of the present application, the communication apparatus for implementing the function of the network device can be a network device, or an apparatus capable of supporting the network device to implement the function, such as a chip system. The apparatus can be installed in the network device or used in matching with the network device. The chip system in the embodiments of the present application can be composed of a chip, or can include a chip and other discrete devices.

[0118] The network architecture and service scenarios described in the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the present application. It is known to those skilled in the art that, with the evolution of communication network architecture and the appearance of new service scenarios, the technical solutions provided by the present application are also applicable to similar technical problems. For example, the present application can be applied to the V2X scenario.

[0119] Based on the communication system 100 shown in FIG. 1, the present application further provides an application scenario, which can be referred to FIG. 2.

[0120] FIG. 2 is a schematic diagram of an application scenario 200 of an embodiment of the present application. In the application scenario 200, a first network device is a source network device providing access services for a terminal device, and a second network device is a target network device providing access services for the terminal device, or in other words, a network device to which a cell currently accessed or camped by the terminal device belongs is the first network device, and the terminal device can be handed over from a cell managed by the first network device to a cell managed by the second network device. The first network device and the second network device can interact with each other. The interface for the first network device and the second network device to interact with each other can refer to the existing standards, and will not be described here.

[0121] In the application scenario 200, the first network device and the second network device can both provide auxiliary computing for the terminal device. The auxiliary computing can be understood as that the network device performs partial or complete computing processing on a service (not limited to the type of service, such as a computing service, a sensing service, or an AI service) of the terminal device, or in other words, the network device participates in the computing processing of the service of the terminal device. The proportion of the computing task amount corresponding to the computing processing of the network device on the service in the overall computing task amount of the service is in the range of 0% to 100%. For example, the proportion of the computing task amount corresponding to the computing processing of the network device on the service in the overall computing task amount of the service is 50% (which can be understood as the auxiliary computing proportion below), or the proportion of the computing task amount corresponding to the computing processing of the network device on the service in the overall computing task amount of the service is 80% (which can be understood as the auxiliary computing proportion below).

[0122] For example, for an uplink service, the terminal device performs partial computing processing (for example, the computing processing proportion (performed by the terminal device) is 40%) on the uplink service, and then sends the uplink service after the partial computing processing to the network device. The network device continues to perform auxiliary computing processing (for example, the auxiliary computing proportion (performed by the network device) is 60%) on the uplink service, so that the complete processing of the uplink service can be completed.

[0123] For example, for a downlink service, the network device performs auxiliary computing processing on the downlink service (for example, the auxiliary computing proportion is 60%), and then sends the downlink service after the auxiliary computing processing to the terminal device. The terminal device continues to perform computing processing corresponding to the auxiliary computing (for example, the computing processing proportion is 40%) on the downlink service, so that the complete processing of the downlink service can be completed.

[0124] Due to the difference in computing capability and load, the proportion of the auxiliary computing provided by the first network device for the terminal device and the proportion of the auxiliary computing provided by the second network device for the terminal device can be inconsistent. For example, for downlink service of the terminal device, the first network device can provide 60% of the auxiliary computing processing for the downlink service, and the second network device can provide 50% of the auxiliary computing processing for the downlink service. When the terminal device switches from the first network device to the second network device, there can be 10% of the computing processing of the downlink service not completed (the terminal device does not obtain the proportion of the auxiliary computing provided by the second network device), which can cause the discontinuity of the computing processing of the downlink service.

[0125] Therefore, the present application provides a communication method and a communication device, which can guarantee the continuity of the computing processing of the service of the terminal device.

[0126] The communication method and the communication device of the embodiments of the present application are described below with reference to the accompanying drawings.

[0127] For the convenience of understanding and description, the communication method of the embodiments of the present application is described below by taking a network side device and a terminal side device, for example, a first network device, a second network device and a terminal device, as an example, but this should not constitute any limitation on the execution subject of the communication method. For example, the network side device can be a network device (such as the first network device and / or the second network device), or a functional module (such as a circuit, a chip or a chip system, etc.), or a logic node, a logic module or software capable of realizing all or part of the function of the network device. Similarly, the terminal side device can be a terminal device, or a functional module (such as a circuit, a chip or a chip system, etc.), or a logic node, a logic module or software capable of realizing all or part of the function of the terminal device.

[0128] When the steps of sending or receiving are performed by a module (such as a circuit, a chip or a chip system, etc.), a logic node, a logic module or software, etc. in the network side device and the terminal side device, the sending / receiving can be understood as communication through a communication interface, an input / output interface, a pin or a circuit, etc.

[0129] FIG. 3 is an interaction flow diagram of a communication method 300 of an embodiment of the present application. As shown in FIG. 3, the method 300 includes:

[0130] S301, the first network device sends request information 1 to the second network device. Correspondingly, the second network device receives the request information 1.

[0131] The request information 1 is used to request the terminal device to switch from the first network device to the second network device, and the request information 1 includes first auxiliary computing information (the first auxiliary computing information can also be replaced by other information such as first auxiliary capability information or first auxiliary computing capability information, etc.), which can indicate the proportion of auxiliary computing provided by the first network device to the service (including but not limited to: uplink service, downlink service, computing service, AI service or sensing service, etc.) of the terminal device, or in other words, the first auxiliary computing information indicates that the first network device can provide the first auxiliary computing to the service of the terminal device. Wherein, the first auxiliary computing information can also be used to indicate the computing action identifier (computing action id), and the computing action identifier can be associated with the corresponding auxiliary computing proportion, such as computing action identifier 1 is associated with auxiliary computing proportion 1, computing action identifier 2 is associated with auxiliary computing proportion 2, and so on.

[0132] Taking the service of the terminal device as an AI service as an example, the data processing process of the AI service includes part or all of the following: data cleaning, model inference and model application. Among them, the proportion of the computing task amount involved in data cleaning is 30%, the proportion of the computing task amount involved in model inference is 40%, and the proportion of the computing task amount involved in model application is 30%, and the first auxiliary computing information can indicate that the first network device can provide 70% of the computing processing for the AI service (i.e. the first network device can perform data cleaning and model inference); or the first auxiliary computing information can indicate that the first network device can provide 40% of the computing processing for the AI service (i.e. the first network device can perform model inference). The above description of the computing task amount is only as an example and is not as a final limitation.

[0133] The above-mentioned data cleaning, model inference and model application, etc. are only as examples, each step (such as data cleaning, model inference or model application) can also include one or more sub-steps (each sub-step can also involve a certain amount of computing task), and the auxiliary computing proportion indicated by the first auxiliary computing information can involve part or all of the one or more sub-steps in each step, which is not limited.

[0134] In addition, for different service types or auxiliary computing granularity (auxiliary computing granularity includes but is not limited to: terminal device granularity, uplink service granularity, downlink service granularity, quality of service flow identifier (QFI) granularity, application flow identifier granularity, etc.), the auxiliary computing proportion indicated by the first auxiliary computing information can be different. The specific description can be referred to Table 1. Wherein, the content shown in Table 1 is only as an example and is not as a final limitation.

[0135] Table 1

[0136] As shown in Table 1:

[0137] For downlink service 1, the first auxiliary computing information indicates that the first network device can provide 60% of computing processing for the downlink service 1 (the auxiliary computing ratio is 60%);

[0138] For downlink service 2, the first auxiliary computing information indicates that the first network device can provide 40% of computing processing for the downlink service 2 (the auxiliary computing ratio is 40%);

[0139] For uplink service 1, the first auxiliary computing information indicates that the first network device can provide 80% of computing processing for the uplink service 1 (the auxiliary computing ratio is 80%);

[0140] For uplink service 2, the first auxiliary computing information indicates that the first network device can provide 30% of computing processing for the uplink service 2 (the auxiliary computing ratio is 30%);

[0141] For terminal device 1, the first auxiliary computing information indicates that the first network device can provide 60% of computing processing for the service of the terminal device 1 (without distinguishing the service type) (the auxiliary computing ratio is 60%);

[0142] For terminal device 2, the first auxiliary computing information indicates that the first network device can provide 50% of computing processing for the service of the terminal device 2 (the auxiliary computing ratio is 50%);

[0143] For QFI 1, the first auxiliary computing information indicates that the first network device can provide 60% of computing processing for the service associated with the QFI 1 (without distinguishing the service type) (the auxiliary computing ratio is 60%);

[0144] For QFI 2, the first auxiliary computing information indicates that the first network device can provide 70% of computing processing for the service associated with the QFI 2 (without distinguishing the service type) (the auxiliary computing ratio is 70%);

[0145] For application flow identifier 1, the first auxiliary computing information indicates that the first network device can provide 80% of computing processing for the service associated with the application flow identifier 1 (without distinguishing the service type) (the auxiliary computing ratio is 80%);

[0146] For the application flow identifier 2, the first auxiliary computation information indicates that the first network device is capable of providing 30% computation processing (the auxiliary computation ratio is 30%) for the service associated with the application flow identifier 2 (without distinguishing the service type).

[0147] In this way, the second network device can determine the first network device's auxiliary computation ratio information according to Table 1. In addition, the second network device can determine that the second network device's auxiliary computation ratio information needs to be sent according to the first network device's auxiliary computation ratio information.

[0148] In some embodiments, the request information 1 can include information for indicating the second network device to send the second auxiliary computation information. The second network device can determine to send the second auxiliary computation information to the first network device according to the information.

[0149] In some embodiments, the request information 1 can not include the first auxiliary computation information. Wherein, the second network device can carry the second auxiliary computation information in the response information 1.

[0150] The above-mentioned request information 1 is only an example, which can be replaced by the switching request information 1 or the switching preparation request information 1 or the switching information 1 and the like.

[0151] In some embodiments, the request information 1 can further include the terminal device's computation capability information, which is used to indicate the terminal device's computation capability. In this way, this can support the second network device to determine the second auxiliary computation information according to the terminal device's computation capability information. For example, the terminal device's computation capability information indicates that the terminal device is capable of performing 60% computation processing for the downlink service 1, and the second network device can determine to provide 40% auxiliary computation processing for the downlink service 1 according to this.

[0152] S302, the second network device sends the response information 1 to the first network device. Correspondingly, the first network device receives the response information 1.

[0153] The response information 1 indicates that the terminal device is allowed to switch from the first network device to the second network device, and the response information 1 includes the second auxiliary computation information (the second auxiliary computation information can also be replaced by other information, such as the second auxiliary capability information or the second auxiliary computation capability information and the like), which indicates the auxiliary computation ratio provided by the second network device for the terminal device's service. The description of the second auxiliary computation information can be referred to the description of the first auxiliary computation information.

[0154] The description of the second auxiliary computation information can also be referred to Table 2. The content shown in Table 2 is only an example and is not finally limited.

[0155] Table 2

[0156] As shown in Table 2:

[0157] For downlink service 1, the second auxiliary computing information indicates that the second network device can provide 50% of computing processing for the downlink service 1 (the auxiliary computing ratio is 50%);

[0158] For downlink service 2, the second auxiliary computing information indicates that the second network device can provide 60% of computing processing for the downlink service 2 (the auxiliary computing ratio is 60%);

[0159] For uplink service 1, the second auxiliary computing information indicates that the second network device can provide 75% of computing processing for the uplink service 1 (the auxiliary computing ratio is 75%);

[0160] For uplink service 2, the second auxiliary computing information indicates that the second network device can provide 40% of computing processing for the uplink service 2 (the auxiliary computing ratio is 40%);

[0161] For terminal device 1, the second auxiliary computing information indicates that the second network device can provide 80% of computing processing for the service of the terminal device 1 (without distinguishing the service type) (the auxiliary computing ratio is 80%);

[0162] For terminal device 2, the second auxiliary computing information indicates that the second network device can provide 40% of computing processing for the service of the terminal device 2 (the auxiliary computing ratio is 40%);

[0163] For QFI 1, the second auxiliary computing information indicates that the second network device can provide 60% of computing processing for the service associated with the QFI 1 (without distinguishing the service type) (the auxiliary computing ratio is 60%);

[0164] For QFI 2, the second auxiliary computing information indicates that the second network device can provide 70% of computing processing for the service associated with the QFI 2 (without distinguishing the service type) (the auxiliary computing ratio is 70%);

[0165] For application flow identifier 1, the second auxiliary computing information indicates that the second network device can provide 50% of computing processing for the service associated with the application flow identifier 1 (without distinguishing the service type) (the auxiliary computing ratio is 50%);

[0166] For the application flow identifier 2, the second auxiliary computation information indicates that the second network device is capable of providing 80% computation processing (the auxiliary computation ratio is 80%) for the service associated with the application flow identifier 2 (without distinguishing the service type).

[0167] In this way, the first network device can determine the auxiliary computation ratio of the second network device according to Table 2.

[0168] When the second network device receives the request information 1, the second network device can evaluate whether to allow the terminal device to switch from the first network device to the second network device. When it is determined that the terminal device is allowed to switch from the first network device to the second network device, the second network device can carry the second auxiliary computation information in the response information 1. When it is determined that the terminal device is not allowed to switch from the first network device to the second network device, the second network device can not carry the second auxiliary computation information in the response information 1.

[0169] Optionally, the auxiliary computation ratio information of whether the second network device provides the service of the terminal device can be decoupled from whether the second network device allows the terminal device to switch from the first network device to the second network device, which is not limited.

[0170] In some embodiments, the determination of whether the second network device allows the terminal device to switch from the first network device to the second network device can be related to the first auxiliary computation information.

[0171] Taking the service of the terminal device as AI service as an example:

[0172] For example, the first auxiliary computation information indicates that the auxiliary computation ratio provided by the first network device is 70%, and when the second network device determines that the auxiliary computation ratio provided is 40%, the second network device determines that the terminal device is not allowed to switch from the first network device to the second network device.

[0173] For example, the first auxiliary computation information indicates that the auxiliary computation ratio capable of being provided by the first network device is 40%, and when the second network device determines that the auxiliary computation ratio provided is 60%, the second network device determines that the terminal device is allowed to switch from the first network device to the second network device.

[0174] For example, the first auxiliary computation information indicates that the auxiliary computation ratio capable of being provided by the first network device is 60%, and when the second network device determines that the auxiliary computation ratio provided is 60%, the second network device determines that the terminal device is allowed to switch from the first network device to the second network device.

[0175] The response information 1 is only an example, and can be replaced by switching response information 1 or switching response information 1 or switching preparation response information 1 or the like.

[0176] S303, the first network device sends the indication information 1 to the terminal device. Correspondingly, the terminal device receives the indication information 1.

[0177] The indication information 1 is only an example, and can be replaced by other terms such as switching command information or switching indication information or the like.

[0178] The indication information 1 is used to indicate that the terminal device is allowed to switch from the first network device to the second network device, and the indication information 1 includes the second auxiliary calculation information.

[0179] The specific description of how the indication information 1 indicates the terminal device to switch from the first network device to the second network device can refer to the description of the existing standard, and will not be repeated here.

[0180] In the above scheme, the first network device can obtain the information of the second network device providing the auxiliary calculation ratio of the service of the terminal device through the response information 1 sent by the second network device, and when determining that the terminal device switches from the first network device to the second network device, the first network device can send the second auxiliary calculation information to the terminal device. The terminal device can adjust the calculation processing ratio of the service according to the second auxiliary calculation information indicating the second network device providing the auxiliary calculation ratio of the service of the terminal device, such as adjusting from the first calculation processing ratio (corresponding to the auxiliary calculation ratio provided by the first network device) to the second calculation processing ratio (corresponding to the auxiliary calculation ratio provided by the second network device), thereby ensuring the continuity of the calculation processing of the service.

[0181] One possible implementation, the method 300 further includes:

[0182] S304, the terminal device sends the switching completion information to the second network device. Correspondingly, the second network device receives the switching completion information.

[0183] The switching completion information can indicate that the terminal device completes the switching from the first network device to the second network device, or the switching completion information indicates that the terminal device has switched from the first network device to the second network device. In this way, the second network device can determine that the terminal device switches from the first network device to the second network device according to the above information.

[0184] In some embodiments, after the terminal device switches from the first network device to the second network device, the terminal device can perform a calculation processing corresponding to the second auxiliary calculation on the data of the service of the terminal device according to the information of the second auxiliary calculation, which can support the processing of the data of the service of the terminal device by the second network device and the terminal device in cooperation.

[0185] The description of the specific process of the terminal device switching from the first network device to the second network device and the description of the related signaling can refer to the existing standards, and will not be described here.

[0186] It should be noted that after the terminal device receives the indication information 1, the terminal device can clear the data packets in the packet data convergence protocol (PDCP) / radio link control (RLC) / media access control (MAC) buffer, and enable the auxiliary calculation ratio indicated by the information of the second auxiliary calculation to perform a corresponding calculation processing on the data packets of the terminal device.

[0187] In one possible implementation, before the terminal device receives the indication information 1, the terminal device sends a request information 2 to the first network device. Correspondingly, the first network device receives the request information 2. The request information 2 is used to request the switching of the network device or the adjustment of the auxiliary calculation ratio for the service of the terminal device.

[0188] For example, the terminal device can determine whether the network device switching is needed according to the local calculation load. When the terminal device determines that the auxiliary calculation ratio provided by the first network device cannot meet the needs of the terminal device, such as the first network device only provides 10% of the auxiliary calculation (the demand of the terminal device for the auxiliary calculation ratio provided by the first network device is 30%), the terminal device can send the request information 2 to the first network device. Correspondingly, the first network device sends the request information 1 to the second network device according to the request information 2.

[0189] Optionally, when the first network device determines that it can meet the auxiliary calculation ratio required by the service of the terminal device, the first network device can adjust the auxiliary calculation ratio for the service of the terminal device, and does not need to send the request information to the second network device.

[0190] Optionally, the request information 2 can further comprise information indicating the computing load of the terminal device. In this way, the first network device can determine whether to perform network device switching according to the computing load of the terminal device. For example, when the first network device determines that the computing load of the terminal device is greater than a threshold (the computing load of the terminal device needs to be reduced), the first network device sends the request information 1 to the second network device.

[0191] Optionally, the request information 2 can further comprise the required proportion of auxiliary computing of the terminal device. In this way, the first network device can determine whether to perform network device switching according to the required proportion of auxiliary computing of the terminal device. For example, when the first network device determines that the required proportion of auxiliary computing of the terminal device can be met, the first network device provides the required proportion of auxiliary computing of the terminal device to the terminal device; when the first network device determines that the required proportion of auxiliary computing of the terminal device cannot be met, the first network device sends the request information 1 to the second network device.

[0192] Optionally, the request information 2 can further comprise information of the requirement of the terminal device for the auxiliary computing of the network device. In this way, the first network device can determine whether to perform network device switching according to the information of the requirement of the terminal device for the auxiliary computing of the network device. For example, when the first network device determines that the requirement of the terminal device for the auxiliary computing of the network device cannot be met, the first network device can send the request information 1 to the second network device.

[0193] It should be noted that in the above switching process, there can be unsuccessfully transmitted data (including one or both of uplink data and downlink data) between the core network element and the terminal device. Therefore, data transmission needs to be performed between the first network device, the second network device and the terminal device to ensure that the unsuccessfully transmitted data between the core network element and the terminal device can be successfully transmitted.

[0194] The data transmission between the first network device, the second network device and the terminal device is described below in combination with FIG. 4 to FIG. 6.

[0195] FIG. 4 is an interactive flow diagram of data transmission 400 according to an embodiment of the present application. The scenario shown in FIG. 4 is a downlink transmission scenario, for example, downlink data transmission between the core network element, the first network device and the terminal device. In this scenario, the terminal device has been switched from the first network device to the second network device. As shown in FIG. 4:

[0196] The core network element sends a first data packet to the first network device;

[0197] The first network device sends a second data packet to the second network device;

[0198] The second network device sends a second data packet to the terminal device according to the first state information.

[0199] The first data packet is any data packet sent by the core network element to the first network device, and the first data packet is a data packet that needs to be calculated and processed. For example, the first data packet is a data packet that needs to be calculated and processed by the first network device and the terminal device, or the first data packet is a data packet that needs to be calculated and processed by the second network device and the terminal device. The first data packet is a data packet that is not successfully transmitted between the core network element and the terminal device.

[0200] Specifically, when the first network device determines that there is a data packet that has not been transmitted or has not been successfully transmitted, the first network device sends the data packet to the terminal device through the second network device, or the second network device can determine the successfully transmitted data packet and the unsuccessfully transmitted data packet according to the PDCP status report (SR) reported by the terminal device (for example, using a bit map method, such as indicating successful transmission by "1" and indicating failed transmission by "0", each bit position in the bit map can be associated with a sequence number (SN), and the SN is associated with a data packet, such as SN1 associated with data packet 1, SN2 associated with data packet 2, and so on), the second network device can indicate to the first network device to retransmit the aforementioned unsuccessfully transmitted data packet (such as the first data packet), and the first network device and the second network device can interact the transmission method of the data packet.

[0201] Through the method shown in FIG. 4, the first network device can send the data packet from the core network element to the second network device, and the second network device sends the second data packet obtained based on the first data packet to the terminal device, which can reduce the data packet loss rate in the downlink data transmission scenario.

[0202] In some embodiments, the second data packet is related to the first data packet. The relationship can be understood as that the second data packet is obtained based on the first data packet. For example:

[0203] For example, the second data packet is a data packet obtained by the first network device performing first auxiliary calculation and processing on the first data packet;

[0204] For example, the second data packet is a data packet obtained by the first network device performing second auxiliary calculation and processing on the first data packet;

[0205] For example, the second data packet is a data packet that has not been processed by the first network device.

[0206] For example, the core network element sends the first network device the first data packet, the first network device performs the first auxiliary calculation processing on the first data packet and obtains the second data packet. Correspondingly, the first network device sends the second network device the second data packet, and the second network device sends the terminal device the second data packet.

[0207] For example, the core network element sends the first network device the first data packet, the first network device performs the second auxiliary calculation processing on the first data packet and obtains the second data packet. Correspondingly, the first network device sends the second network device the second data packet, and the second network device sends the terminal device the second data packet.

[0208] Specifically, the first network device determines the information of the second auxiliary calculation through the response information 1, and when it is determined that the second auxiliary calculation is supported, the first network device performs the second auxiliary calculation on the first data packet, which can support the second network device to transparently transmit the second data packet to the terminal device.

[0209] For example, the core network element sends the first network device the first data packet, the first network device does not provide the first auxiliary calculation and / or the second auxiliary calculation on the first data packet, or in other words, the first data packet is an original data packet, and the second data packet is also an original data packet.

[0210] In this way, this can support the second network device to complete the transmission processing of the second data packet according to the relationship between the second data packet and the first data packet.

[0211] In the embodiment of the application, the second network device sends the terminal device the second data packet according to the first state information, comprising:

[0212] When the first state information indicates that the second data packet is a data packet obtained by the first network device performing the first auxiliary calculation processing, the second network device directly sends the terminal device the second data packet, and the terminal device performs the calculation processing corresponding to the first auxiliary calculation processing on the second data packet, so as to complete the complete processing process of the first data packet.

[0213] When the first state information indicates that the second data packet is a data packet obtained by the first network device performing the second auxiliary calculation processing, the second network device directly sends the terminal device the second data packet, and the terminal device performs the calculation processing corresponding to the second auxiliary calculation processing on the second data packet, so as to complete the complete processing process of the first data packet.

[0214] When the first status information indicates that the second data packet is a data packet that has not been processed by the first auxiliary computation processing or the second auxiliary computation processing, the second network device performs the second auxiliary computation processing on the second data packet, and sends the second data packet processed by the second auxiliary computation processing to the terminal device. The terminal device performs computation processing corresponding to the second auxiliary computation processing on the second data packet processed by the second auxiliary computation processing, so that a complete processing process of the first data packet can be completed.

[0215] When the first status information indicates that the second data packet is a data packet that has not been processed by the first auxiliary computation processing or the second auxiliary computation processing, the second network device performs the second auxiliary computation processing on the second data packet, and sends the second data packet processed by the second auxiliary computation processing to the terminal device. The terminal device performs computation processing corresponding to the second auxiliary computation processing on the second data packet processed by the second auxiliary computation processing, so that a complete processing process of the first data packet can be completed.

[0216] In this way, the second network device can complete transmission processing of the second data packet according to the computation state of the second data packet.

[0217] In some embodiments, the first status information indicates the computation state of the second data packet. The computation state of the second data packet includes any one of the following:

[0218] processed by the first auxiliary computation processing;

[0219] processed by the second auxiliary computation processing,

[0220] not processed by the auxiliary computation processing.

[0221] Correspondingly, the second network device can complete transmission of the corresponding second data packet according to different computation states. For specific descriptions, refer to the description of the first status information above, which will not be repeated here.

[0222] In some embodiments, the first status information is indicated by the first network device to the second network device. In this way, the second network device can perform transmission of the second data packet according to the first status information.

[0223] In some embodiments, the first status information is predefined by a protocol. In this way, the second network device can complete transmission of the second data packet according to the predefined manner.

[0224] In some embodiments, the second network device sends the first status information to the terminal device. In this way, the terminal device can complete processing of the second data packet according to the first status information.

[0225] For example, the first status information indicates that the second data packet is a data packet that has undergone the first auxiliary computation processing or the second auxiliary computation processing, and the terminal device can perform computation processing corresponding to the first auxiliary computation on the second data packet, or the terminal device can perform computation processing corresponding to the second auxiliary computation on the second data packet.

[0226] For example, the first status information indicates that the second data packet is a data packet that has not undergone the first auxiliary computation processing or the second auxiliary computation processing, and the terminal device can perform complete computation processing on the second data packet.

[0227] In some embodiments, the first status information can also be preconfigured to the terminal device. In this way, the terminal device can complete processing of the second data packet according to the preconfigured first status information.

[0228] It should be noted that the first network device and the second network device can interact with each other about the transmission mode of the second data packet (such as whether auxiliary computation processing is required or not), and the second network device and the terminal device can also interact with each other about the transmission mode of the second data packet (such as whether auxiliary computation processing is required or not), and the specific interaction mode is not limited, for example, the first network device and the second network device can negotiate or instruct each other to interact with each other about the transmission mode of the data packet.

[0229] Through the method shown in FIG. 4, when there is unsuccessfully transmitted downlink data between the core network element and the terminal device, the first network device can send the data packet from the core network element to the second network device, and the second network device can send the unsuccessfully transmitted downlink data to the terminal device, which can reduce the data packet loss rate in the downlink data transmission scenario.

[0230] FIG. 4 is an example of the first data packet. When there are multiple data packets, the computation state of each data packet can be different, for example, the computation state of data packet 1 is that it has undergone the first auxiliary computation processing, the computation state of data packet 2 is that it has undergone the second auxiliary computation processing, and the computation state of data packet 3 is that it has not undergone auxiliary computation processing. The computation state of each data packet can also be the same, for example, the computation state of data packet 1 is that it has undergone the first auxiliary computation processing, the computation state of data packet 2 is that it has undergone the first auxiliary computation processing, and the computation state of data packet 3 is also that it has undergone the first auxiliary computation processing. Correspondingly, the first network device, the second network device, and the terminal device can interact with each other about the computation state information of each data packet (the computation state of each data packet can be indicated by a bit map or a sequence number range) (the indication mode can be used, or the preconfigured mode can be used, which is not limited).

[0231] FIG. 5 is an interaction flow diagram of data transmission 500 according to an embodiment of the present application. The scenario shown in FIG. 5 is an uplink transmission scenario, for example, uplink data transmission between a core network element, a second network device, a first network device, and a terminal device. The terminal device has been handed over from the first network device to the second network device. As shown in FIG. 5:

[0232] the terminal device sends a third data packet to the first network device;

[0233] the first network device sends a fourth data packet to the second network device;

[0234] the second network device sends the fourth data packet to the core network element according to the second state information.

[0235] The third data packet is any data packet sent by the terminal device to the first network device (the sending time of the third data packet is a time when the terminal device has not been handed over from the first network device to the second network device), and the third data packet is a data packet that needs to be calculated and processed. For example, the third data packet is a data packet that needs to be calculated and processed by the first network device and the terminal device. The third data packet is a data packet that has not been successfully sent by the first network device to the core network element.

[0236] Through the method described in FIG. 5, the terminal device can send a data packet that has not been successfully transmitted between the terminal device and the core network element to the second network device through the first network device, which can reduce the data packet loss rate in the uplink data transmission scenario.

[0237] In some embodiments, the fourth data packet is related to the third data packet. The relationship can be understood as that the fourth data packet is obtained based on the third data packet. For example:

[0238] For example, the fourth data packet is a data packet obtained by the first network device performing first auxiliary calculation and processing on the third data packet;

[0239] For example, the fourth data packet is a data packet that has not been processed by the first network device, and the third data packet is a data packet obtained by the terminal device performing calculation and processing corresponding to the first auxiliary calculation.

[0240] For example, the terminal device sends a third data packet to the first network device, the first network device performs first assistant calculation processing on the third data packet, and attempts to send the third data packet after the first assistant calculation processing to the core network element. When the first network device fails to successfully send the third data packet after the first assistant calculation processing to the core network element, the first network device can send a fourth data packet (the fourth data packet is the data packet obtained by the first network device performing the first assistant calculation processing on the third data packet) to the second network device, and the second network device sends the fourth data packet to the core network element. In this way, the data packet loss rate in the uplink scenario can be reduced.

[0241] For example, the terminal device sends a third data packet to the first network device, the first network device performs first assistant calculation processing on the third data packet, and attempts to send the third data packet after the first assistant calculation processing to the core network element. When the first network device fails to successfully send the third data packet after the first assistant calculation processing to the core network element, the first network device performs fallback processing on the third data packet after the first assistant calculation processing to obtain the third data packet received from the terminal device, and sends a fourth data packet (the fourth data packet is the third data packet received from the terminal device by the first network device) to the second network device. The second network device performs first assistant calculation processing on the fourth data packet (the second network device supports the first assistant calculation), and sends the fourth data packet after the first assistant calculation processing to the core network element. In this way, the data packet loss rate in the uplink scenario can be reduced.

[0242] In summary, the second network device can complete the transmission processing of the fourth data packet according to the relationship between the fourth data packet and the third data packet.

[0243] In some embodiments, the second network device sends the fourth data packet to the core network element according to the second state information, including:

[0244] When the second state information indicates that the fourth data packet is a data packet obtained by the first network device performing the first assistant calculation processing, the second network device directly sends the fourth data packet to the core network element.

[0245] When the second state information indicates that the fourth data packet is a data packet without the first assistant calculation processing, the second network device performs the first assistant calculation processing on the fourth data packet, and sends the fourth data packet after the first assistant calculation processing to the core network element.

[0246] In some embodiments, the second state information indicates the calculation state of the fourth data packet. The calculation state of the fourth data packet includes any one of the following:

[0247] after the first auxiliary computation process;

[0248] without the auxiliary computation process.

[0249] Correspondingly, the second network device can complete transmission of the fourth data packet according to different computation states. For specific description, refer to the description of the second state information above, which will not be repeated.

[0250] In this way, this can support the second network device to complete transmission processing of the fourth data packet according to the computation state of the fourth data packet.

[0251] In some embodiments, the second state information is indicated by the first network device to the second network device. In this way, the second network device can transmit the fourth data packet according to the second state information.

[0252] In some embodiments, the second state information is predefined by a protocol. In this way, the second network device can complete transmission of the data packet from the first network device according to the predefined manner.

[0253] In some embodiments, the terminal device can send the second state information to the first network device. In this way, the first network device can complete processing of the third data packet according to the second state information.

[0254] In some embodiments, the second state information can also be preconfigured to the first network device. In this way, the first network device can complete processing of the third data packet according to the preconfigured second state information.

[0255] It should be noted that the first network device and the second network device can interact on the transmission manner of the fourth data packet (such as whether auxiliary computation processing is needed, etc.), and the specific interaction manner is not limited.

[0256] Through the method shown in FIG. 5, when there is unsuccessfully transmitted uplink data between the first network device and the terminal device, the first network device can send the unsuccessfully transmitted uplink data to the core network element through the second network device, which can reduce the probability of packet loss.

[0257] FIG. 5 is an example of the fourth data packet, when there are multiple data packets, the computing state of each data packet can be different, for example, the computing state of data packet 1 is that it has undergone the first auxiliary computing processing, the computing state of data packet 2 is that it has not undergone the first auxiliary computing processing; the computing state of each data packet can also be the same, for example, the computing state of data packet 1 is that it has undergone the first auxiliary computing processing, the computing state of data packet 2 is that it has undergone the first auxiliary computing processing, and the computing state of data packet 3 is also that it has undergone the first auxiliary computing processing. Correspondingly, the first network device, the second network device and the terminal device can interact the information of the computing state of each data packet, which can be referred to the foregoing description and will not be described here.

[0258] FIG. 6 is an interaction flow diagram of data transmission 600 according to an embodiment of the present application. The scenario shown in FIG. 6 is an uplink transmission scenario, for example, uplink data transmission between the core network element, the second network device, the first network device and the terminal device. Among them, the terminal device has been switched from the first network device to the second network device. As shown in FIG. 6:

[0259] the terminal device sends a fifth data packet to the second network device;

[0260] the second network device sends the fifth data packet to the first network device;

[0261] the first network device sends a sixth data packet to the second network device;

[0262] the second network device sends the sixth data packet to the core network element.

[0263] The fifth data packet is any one data packet sent by the terminal device to the second network device, and the fifth data packet is a data packet that needs to be processed by the first network device for the first auxiliary computing processing. Among them, the fifth data packet is a data packet processed by the terminal device for the computing processing corresponding to the first auxiliary computing processing. Or, the fifth data packet is a data packet that has not been successfully transmitted between the terminal device and the core network element. It should be noted that the above content is an example of the first network device processing the fifth data packet for the first auxiliary computing processing, but other network devices supporting the first auxiliary computing processing can also process the fifth data packet for the auxiliary computing processing, such as the third network device (not shown in FIG. 2) and the like.

[0264] Through the method shown in FIG. 6, after the terminal device is switched from the first network device to the second network device, the first network device can process the data packet that has not been successfully transmitted between the terminal device and the core network element from the second network device, and send the processed data packet to the second network device, thereby reducing the data packet loss rate in the uplink data transmission scenario.

[0265] In some embodiments, the sixth data packet is a data packet obtained by the first network device performing the first auxiliary computation processing on the fifth data packet.

[0266] When the second network device does not support the first auxiliary computation processing, the second network device sends the fifth data packet to the first network device. When the second network device supports the first auxiliary computation processing, the second network device can complete the first auxiliary computation processing on the fifth data packet by itself, and send the sixth data packet to the core network element.

[0267] In some embodiments, the terminal device sends a seventh data packet to the second network device, the seventh data packet being a data packet on which the terminal device performs computation processing corresponding to the second auxiliary computation processing. Correspondingly, the second network device performs the second auxiliary computation processing on the seventh data packet to obtain an eighth data packet, and sends the eighth data packet to the core network element.

[0268] In some embodiments, the terminal device sends a ninth data packet to the second network device, the ninth data packet being a data packet that has not been subjected to computation processing. Correspondingly, the second network device performs complete computation processing (including the second auxiliary computation processing and computation processing corresponding to the second auxiliary computation processing) on the ninth data packet, and sends the ninth data packet subjected to the complete computation processing to the core network element.

[0269] Optionally, the terminal device can also send a data packet subjected to complete computation processing to the second network device, and the second network device directly sends the data packet to the core network element.

[0270] In some embodiments, the terminal device sends third state information to the second network device. Correspondingly, the second network device receives the second state information. The second state information is used to indicate the computation state of the fifth data packet.

[0271] Exemplarily, the computation state of the fifth data packet includes:

[0272] a data packet subjected to computation processing corresponding to the first auxiliary computation;

[0273] a data packet subjected to computation processing corresponding to the second auxiliary computation;

[0274] a data packet subjected to complete computation processing;

[0275] a data packet that has not been subjected to computation processing.

[0276] Correspondingly, the second network device can perform corresponding processing on the fifth data packet according to different computation states of the fifth data packet.

[0277] For example, the third status information indicates that the fifth data packet is a data packet that has undergone a calculation process corresponding to the first auxiliary calculation, and when the second network device does not support the first auxiliary calculation process, the second network device sends the fifth data packet to the first network device.

[0278] For example, the third status information indicates that the fifth data packet is a data packet that has undergone a calculation process corresponding to the second auxiliary calculation, and the second network device can perform the second auxiliary calculation process on the fifth data packet and send the fifth data packet that has undergone the second auxiliary calculation process to the core network element.

[0279] For example, the third status information indicates that the fifth data packet is a data packet that has undergone a complete calculation process, and the second network device directly sends the fifth data packet to the core network element.

[0280] For example, the third status information indicates that the fifth data packet is a data packet that has not undergone a calculation process, the second network device performs a complete calculation process on the fifth data packet, and sends the fifth data packet that has undergone the complete calculation process to the core network element.
