Description

User data processing method and device

technical field

The present invention relates to the field of communication technologies, and in particular, to a method and device for processing user data.

Background technique

In the wireless evolution network, mobile phone applications are becoming more and more extensive, and various applications that occupy high bandwidth, such as video and online games, will occupy a large amount of network bandwidth resources. For access network devices, due to the limited resources of the access network devices, when these applications use network resources in large quantities, the access network devices may be congested. In view of the above situation, in the prior art, the gateway device or TDF (Traffic Detection Function, data detection function entity) on the network side differentiates all downlink data packets according to some conditions, for example, adding in the data packets A processing identifier classifies the downlink data packets into different types, then the access network device can perform differential processing on the downlink data packets according to different types. For example, the network side generates a data packet priority according to information such as the type of the user, the application type of the data packet, etc., then the data flow can divide the data packet into several categories according to different priorities, and the access network device receives the downlink data. After the packets are received, differentiated processing is performed according to the priority of the data packets. For example, those with high priorities are processed first, while those with low priorities may be processed later or even discarded.

There are at least the following problems in the prior art: the processing identifiers in the data stream are generated by each operator according to the self-defined conditions, and how the access network device processes these data packets is also self-defined by each operator.

In this way, after the downlink data packet arrives at the access network of the roaming operator, the meaning of the data packet processing identifier defined by the roaming operator may be different from that of the home location, then the roaming access network processes the data packets from the home gateway device when processing the data packets from the home gateway device. , according to the processing identification of the data packet, the data packet is processed according to the processing rules of the roaming processing identification, so that the data packet cannot be processed normally.
