For example, the data path of the present invention can be divided into a default data path and a specific data path. The present invention is not limited to this, and the classification is only used to describe the applicable scenario of the technical solution of the present invention. The default data path refers to a data path established for the user in advance before the user data is reached. The establishment or maintenance of the default data path includes the following three situations: one is that the UE initially enters the network, the other is when the UE moves, and the third is the user idle mode exit, except for the default data path, in some specific cases, it needs to be the user or The user service establishes a specific data path, and the factors that trigger the establishment of a specific data path include but are not limited to:

The SNC determines that the adjustment threshold is reached, and the dynamic adjustment triggers the establishment of a specific data path.

FIG. 3 is a flowchart of a second embodiment of the user data processing method provided by the present invention. As shown in FIG. 3, the user data processing method in this embodiment is directed to the establishment of a default data path when the user initially enters the network, which may include :

The authorization authentication process is performed between the S20K SNC and the UE.

Specifically, the UE is initially in the network, and the SNC and the UE perform the authentication process of the network. In the process of the authentication, the identifier of the current radio node attached to the UE is reported to the SNC, that is, the SNC obtains the authentication process. The radio node information currently connected by the UE, and the specific process of the step can be operated by referring to the prior art manner. .

S202: The SNC sends a message to the UE that includes an IP address for the UE.

S203: The UE sends an IP address receiving response message to the SNC.

Specifically, considering load balancing, the SNC can evenly distribute IP addresses across network segments. After receiving the IP address, the UE sends an IP address acceptance response message to the SNC. The two messages may be sent separately, or may be carried in the interactive message in the authorization authentication process, and the SNC receives the response message sent by the IP address sent by the UE. That is, the determination establishment process of the path rule for processing the user data of the UE is triggered.

S204: The SNC determines, according to the obtained control plane information, processing path information of a data path for processing user data of the UE and processing policy information of the node in the data path. The data path mainly includes two aspects: processing path information and processing policy information of nodes in the data path, and the processing path information includes node information on the data path (for example, including entry, FN, and Radio node) and forwarding policy information of nodes on the data path. The processing policy information includes a processing method and a processing parameter of the node processing the user data on the data path. In this embodiment, the processing path information may be user granularity or data flow granularity.

When determining the data path, the SNC mainly considers: UE location information, service type, node load (including remaining computing power of nodes, remaining bandwidth between nodes, remaining storage capacity of nodes, etc.);

The user service information determines the type of the necessary processing function that the user needs to pass, and obtains the node type on the data path. According to the status information of the load/bandwidth/delay of the various function nodes that the SNC itself has, select the specific function. The status information of the node and the function node can be reported to the SNC periodically by the function node, or can be initiated by the SNC. If the information is obtained, the processing information of the function node is obtained according to the information such as the subscription service information, user information, and network status. Forming a complete data path, including each functional node that the data stream passes successively and the processing strategy and processing parameters of the data flow of the functional node.

Specifically, the SNC sends the processing path information and the processing policy information determined in S204 to the function node of the entry point Entry and the data path respectively. Generally, the Entry focuses on the processing path information sent by the SNC, and the user data. After the data packet arrives, Entry can mark the data packet header according to the processing path information, indicating the transmission path of the data packet, so that the data packet is transmitted on the data path. Entry can also accept some processing strategies, such as scheduling priority, etc., and send them to the corresponding FN in the packet header. FN is more concerned with processing policy information, and FN processes the user's data packets according to the processing policy delivered by the SNC.

S404: The SNC determines, according to the obtained control plane information, processing path information of a data path of processing user data of the UE and processing policy information of the node in the data path.

Specifically, the data path determination of the SNC may determine the hop nodes on the default data path in the manner of S204 in the embodiment shown in FIG. 3, and the process of determining is the same as S204 in the embodiment shown in FIG. If the SNC still stores the processing path information and processing strategy information of the data path of the user before the idle state, the processing path information and processing policy information of the part of the established data path may be directly used, if the user is idle When the movement of the Radio node occurs, the last hop node is updated. If the user does not move across the Radio node in the idle state, the last hop node Radio node does not need to be updated.

Mode operation.

5502. The UE sends a service QoS request message including the QoS parameter and the service description information to the SNC.
