According to the mapping relationship between the business requirement and the data processing function combination and the mapping relationship between the data processing function combination and the data processing identifier, determine that the data processing identifier and the data processing function combination include at least two data processing functions.

Specifically, the business requirement may be a service ID (service ID) or a service level agreement (Service Level Agreement, SLA) requirement or a quality of service (Quality of Service, QoS) requirement or a content ID, based on the service ID or SLA requirement or QoS requirement or The mapping relationship between content IDs and data processing IDs determines the data processing IDs.

In an optional embodiment of the present disclosure, the mapping relationship is configured by the network side or determined by the terminal 90, and the mapping process is completed by a non-access stratum (Non Access Stratum, UE NAS) of the terminal 90.

The mapping relationship may be sent to a user equipment (User Equipment, UE) in advance through a radio resource control (Radio Resource Control, RRC) message.

Specifically, the mapping relationship can be implemented in the following ways:

1) As shown in FIG. 2 , the mapping relationship between the business requirements and the data processing function combination is configured by the network, and the mapping relationship between the data processing function combination and the data processing ID is configured by the network.

For example, when the functional module is "retransmission", the specific scheme can be automatic repeat request (Automatic Repeat-reQuest, ARQ) retransmission, or type ( Type) I hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ), or Type II HARQ, or Type III HARQ, etc.

The specific process is as follows:

1) The first node sends the mapping relationship to the UE in advance through an RRC message. The RRC message may be: carrying the mapping relationship between the service ID/SLA requirement/QoS requirement/content ID and the data processing ID, or, carrying the data processing ID and the data processing ID. Correspondence between functional modules, further, an uplink grant (UL Grant) can also be sent to the terminal;

2) The terminal associates the data packet with the data processing ID based on the service ID/SLA requirement/QoS requirement/content ID carried in the high-level data packet header, or, based on the data processing ID, uplink allocated resource size and/or data transmission priority , to generate the data block to be transmitted. In the header of the data block to be transmitted, at least the data processing ID is included;

3) The terminal transmits the uplink data to the second node (target node), and the second node processes the data based on information such as the data processing ID, including the modification of the data header;

Mode 2: Determine the data processing ID based on the mapping relationship between the data processing function combination and the data processing ID. The mapping relationship is configured by the network;

The mapping process can be done by UE NAS;

Different from mode 1, the mapping between the service requirements and the data processing function combination is determined by the UE, and the association relationship between the data processing function combination and the data processing ID is configured by the network.

Mode 3: Based on the service ID or SLA requirement or QoS requirement or content ID, the UE determines a series of processing functions (eg, based on an AI algorithm), and identifies the processing function combination with a data processing ID.

Further, the data processing ID is associated with a specific usage scheme or algorithm in a series of functional modules, for example, when the functional module is "retransmission", the specific scheme can be ARQ retransmission or Type I HARQ or Type II HARQ or Type III HARQ Wait.

Step 2: Generate a data block to be transmitted based on the data processing ID, and the resource size and/or data transmission priority allocated by the uplink. The header of the data block to be transmitted includes at least the data processing ID, and may also include: source node ID, one or more source function IDs, one or more source function scheme IDs, one or more target node IDs, one or more A target function ID, and one or more target function scheme IDs.

Step 3: After receiving the data block, the target node performs corresponding processing on the data based on the data processing ID. The processing of the data includes not only the processing of the payload part, but also the processing of the packet header.

Further, the processed data needs to be forwarded to the next-hop target node.
