Problems solved by technology
[0003] Therefore, a phenomenon that may occur in the protocol data session is that when the data limit of the terminal device is greater than the data limit of the network element node, it may cause the message passing through the terminal device to be unable to pass through the network element node directly due to its large size. Fragmentation processing has to be performed at network element nodes, thus affecting communication efficiency
[0004] In the prior art, the data limit of the terminal equipment is static, which means that it cannot be adjusted adaptively according to the specific conditions of the network element nodes
Therefore, it is impossible to solve the problem of fragmentation processing of a large number of packets at network element nodes, resulting in a decrease in communication efficiency

[0038] In the IPv6-based protocol data session, that is, PDU (full name Protocol Data Unit) Session, terminal equipment and network element nodes have their own data limits (ie MTU, full name Maximum Transmission Unit). The data limit is used to determine the maximum volume of communication packets that can pass through the terminal equipment...

The invention discloses a data limit value determination method and device, and the method comprises the steps: determining a first data limit value corresponding to a network element node if a terminal message fragmented by the network element node meets a preset condition, wherein the terminal message is a communication message sent by terminal equipment; determining a minimum data limit value corresponding to the network element node according to the first data limit value; and determining a second data limit value corresponding to the terminal equipment based on the minimum data limit value. According to the invention, the dynamic setting of the data limit value of the terminal equipment is realized, the data limit value of the terminal equipment is close to the minimum data limit value of the network element node, most of terminal messages passing through the terminal equipment can directly pass through each network element node, and further fragmentation processing is not needed, so that the communication efficiency is improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for determining a data limit value. Background technique [0002] In an IPv6-based protocol data session, some network element nodes are usually used to statically configure the data limit of the terminal device, that is, to determine the maximum size of the uplink and downlink packets passing through the terminal device. Similarly, each network element node in the protocol data session also has a corresponding data limit, that is, the maximum size of an uplink and downlink message passing through a terminal device. [0003] Therefore, a phenomenon that may occur in the protocol data session is that when the data limit of the terminal device is greater than the data limit of the network element node, it may cause the message passing through the terminal device to be unable to pass through the network element node directly due to its large size. ...
