Therefore, a phenomenon that may occur in the protocol data session is that when the data limit value of the terminal device is greater than the data limit value of the network element node, a message passing through the terminal device may not pass through the network element node directly due to the large size, and then the fragmentation processing has to be performed at the network element node, thereby affecting the communication efficiency.

Detailed Description
In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions according to the embodiments of the present invention will be clearly described in the following with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In an IPv6 based protocol data Session, namely PDU (full Protocol Data Unit) Session, both the end device and the network element node are provided with respective data limits (namely MTU, full Maximum Transmission Unit). The data limit is used to determine the maximum volume of communication messages that can pass through the terminal device and the network element node. If the volume of the communication message which needs to pass is larger than the data limit value, the terminal equipment and the network element node carry out the fragmentation processing on the communication message.
The network element nodes in the protocol data session may include session management network elements (i.e., SMF, collectively Session Management Function), user plane network elements (UPF, collectively User Plane Function), and the like. Currently, the data limit of the terminal device is generally statically configured by using an SMF network element.
Therefore, a phenomenon that may occur in a protocol data session is that when the data limit of the terminal device is greater than the data limit of the network element node, a message passing through the terminal device cannot directly pass through the network element node because of a large volume, and has to be fragmented at the network element node.
Based on the above, it will be appreciated that the data limit of the terminal device will have a direct impact on the overall communication efficiency in the protocol data session. If the data limit value of the terminal equipment is too large, a large number of communication messages are subjected to slicing processing at various network element nodes, so that the communication efficiency is reduced. If the data limit of the terminal device is too small, the terminal device has to perform excessive fragmentation processing on the original communication message, which also results in a decrease in communication efficiency. Therefore, the data limit value of the terminal equipment is preferably close to the data limit value of the network element node, the number of times of the time division processing is less, and the overall communication efficiency of the protocol data session is higher.
In the prior art, however, the data limit configuration of the terminal device with the SMF network element belongs to a static configuration. The static configuration means that the data limit value of the terminal device cannot be adaptively adjusted according to the specific situation of the network element node, that is, cannot reach a state that is relatively close to the data limit value of the network element node in real time. The problem of reduced communication efficiency caused by the fragmentation processing of a large number of messages occurring at the network element node cannot be solved. There is a lack of a solution in the prior art for dynamically configurable data limits of terminal devices.
Therefore, the embodiment of the invention provides a data limit value determining method to at least solve the above technical problems in the prior art. In this embodiment, the execution body of the method is a user plane network element, that is, the user plane network element is used to implement the configuration of the data limit value for the terminal device. As shown in fig. 1, the method in this embodiment includes the following steps:
step 101, if the terminal message processed by the network element node in a slicing way meets a preset condition, determining a first data limit value corresponding to the network element node.
The network element node in this embodiment refers generally to various types of network element nodes included in a protocol data session, such as a session management network element, a user plane network element, and the like. The execution body of the embodiment is specifically a user plane network element in the network element node. That is, in this embodiment, dynamic configuration of the data limit value of the terminal device will be implemented based on the user plane network element.
The terminal message is a communication message sent by the terminal equipment. The communication message may be an uplink message or a downlink message. That is, any communication message passing through the terminal device may be defined as a terminal message. Specifically, the terminal message may be a communication message directly sent by the terminal device as the sending end. Or, the terminal message may also be a communication message forwarded by the terminal device as a transit end from other network element nodes. Based on the data limit value of the network element node, the terminal message may or may not be fragmented at each network element node.
In this embodiment, whether the terminal message meets the preset condition is determined according to the actual situation of the network element node for the terminal message fragmentation processing. For example, the number of all terminal messages received by the user plane network element can be determined within a specific time range; and determining the number of terminal messages subjected to slicing processing. When the ratio of the number of the terminal messages subjected to the slicing processing to the number of all the terminal messages reaches a specific threshold, the terminal messages subjected to the network element node slicing processing at the moment are considered to meet the preset condition. That is, at this time, the number of times the network element node performs the fragmentation processing may be considered to be excessive, resulting in an influence on the communication efficiency. That is, the data limit value of the terminal device is not matched with the data limit value of the network element node, and the data limit value of the terminal device needs to be adjusted.
It should be noted that the above network element node may include two specific cases for terminal message slicing processing. For example, the user plane network element performs slicing processing on the terminal message, so that the user plane network element determines whether the terminal message duty ratio of the slicing processing reaches a specific threshold value. Or, other network element nodes except the user plane network element can also carry out the fragmentation processing on the terminal message; the terminal message processed by the segmentation is forwarded to the user plane network element through the terminal equipment; and then the user plane network element determines whether the terminal message duty ratio of the node slicing processing of other network elements reaches a specific threshold value.
In both cases, whether the user plane network element or other network element node needs to perform the fragmentation processing depends on the data limit set by itself. On the premise that the terminal message processed by the network element node in a fragmented manner meets the preset condition, the user plane network element determines a first data limit value corresponding to each network element node in the protocol data session. The first data limit value is a data limit value set by each network element node.
Step 102, determining a minimum data limit corresponding to the network element node according to the first data limit.
The first data limit values corresponding to the network element nodes are often not the same. It will be appreciated that the smaller the data limit of a network element node, the greater the likelihood that a fragmentation process will occur at that network element node. That is, the network element node with the smallest data limit corresponds to the "narrowest" communication channel in the protocol data session. In this embodiment, the minimum data limit value in each network element node, that is, the minimum value in each first data limit value, is determined, so as to be used as the basis for setting the data limit value of the terminal device subsequently.
And 103, determining a second data limit corresponding to the terminal equipment based on the minimum data limit.
The minimum data limit represents the "narrowest" communication channel in a protocol data session, and is the most frequent point at which fragmentation occurs. If the data limit of the terminal device is close to the minimum data limit, this means that the terminal message passing through the terminal device can mostly pass through the respective network element node directly without further fragmentation. The overall communication efficiency of the protocol data session is high. In this embodiment the second data limit value corresponding to the terminal device will be determined based on the minimum data limit value. The second data limit value is the data limit value finally set for the terminal device in this embodiment.
In some cases, the minimum data limit may be displayed directly as the second data, thereby setting the terminal device. In other cases, it is provided that the data limit of the terminal device is required to lie within a specific interval, i.e. a preset upper data limit (maximum value) and a preset lower data limit (minimum value) are present. In this case, the second data limit value corresponding to the terminal device may be determined in common based on the minimum data limit value, the data limit value upper limit value, and the data limit value lower limit value. Specifically, if the minimum data limit is greater than the upper data limit, setting the upper data limit as a second data limit; if the minimum data limit is less than the data limit lower limit, setting the data limit lower limit as a second data limit; if the minimum data limit is between the upper data limit and the lower data limit, the minimum data limit is set to the second data limit.
It should be noted that, in this embodiment, the specific manner of setting the second data limit value to the terminal device may be to adjust the data limit value parameter in the route announcement packet corresponding to the terminal device to determine the second data limit value corresponding to the terminal device. The route advertisement message is an RA (generic name Router Advertisment) message in the protocol data session. And adjusting the data limit parameter in the route announcement message can be modifying the MTU field in the route announcement message or adding the MTU field if the MTU field does not exist originally. And setting the data limit value of the terminal equipment through the adjusted route notification message.
The route notification messages sent to the terminal equipment by the various network element nodes all need to pass through the user plane network element. The user plane network element is the network element node which is most convenient for adjusting the data limit value parameter in the route notification message in various different types of protocol data sessions (such as a 5G core network and a 5G access network). Therefore, in this embodiment, the user plane network element is selected as the execution body, and the dynamic setting of the data limit value of the terminal device can be implemented according to the overall situation of the protocol data session, so as to improve the communication efficiency.
In addition, it should be noted that, in this embodiment, the method may be periodically and repeatedly performed, so as to adjust the data limit of the terminal device periodically, so that the overall communication efficiency of the protocol data session is always maintained under ideal conditions. The specific period duration may be set according to the requirement, which is not limited in this embodiment.
According to the technical scheme, the beneficial effects of the embodiment are as follows: determining a minimum data limit value of the network element node according to the first data limit value, and determining a second data limit value of the terminal equipment based on the minimum data limit value; the dynamic setting of the data limit value of the terminal equipment is realized, so that the data limit value of the terminal equipment is close to the minimum data limit value of the network element nodes, most of terminal messages passing through the terminal equipment can directly pass through each network element node without further slicing processing, and the communication efficiency is improved.
Fig. 1 shows only a basic embodiment of the method according to the invention, on the basis of which certain optimizations and developments are made, but other preferred embodiments of the method can also be obtained.
Fig. 2 shows another embodiment of the data limit determining method according to the present invention. The present embodiment specifically describes a case where the user plane network element itself performs the fragmentation processing on the basis of the foregoing embodiments. The method specifically comprises the following steps:
step 201, determining a first data limit value corresponding to a plurality of sub-interfaces of the user plane network element if the number of terminal messages processed by the user plane network element in a fragmentation way reaches a first proportional threshold.
If the data limit value of the terminal equipment is larger than the data limit value of the user plane network element, the volume of the terminal message after the fragmentation processing of the terminal equipment can be equal to the data limit value of the terminal equipment, and the terminal message cannot directly pass through the user plane network element and needs to be fragmented again in the user plane network element. At this time, a decrease in communication efficiency may be caused. In this embodiment, the total number of terminal messages received by the user plane network element in a specific time range may be calculated as a1, where the number of terminal messages that are subjected to slicing processing and whose volume is greater than the data limit value of the user plane network element is b1, so that the ratio of b1 to a1 is the duty ratio of the terminal messages that are subjected to slicing processing by the user plane network element. When the ratio reaches a preset first ratio threshold, namely the number of times of the user plane network element fragmentation processing is considered to be excessive, the data limit value of the terminal equipment is not matched with the data limit value of the user plane network element, and the data limit value of the terminal equipment needs to be adjusted. Therefore, the first data limit value corresponding to each of the plurality of sub-interfaces of the user plane network element will be further determined.
In practical situations, the user plane network element includes a plurality of subinterfaces, which are respectively connected with other components in the protocol data session. Each sub-interface has a respective first data limit. It should be noted that, the first data limit value corresponding to the sub-interface will be determined according to the standard data limit value of the sub-interface and the package volume corresponding to the sub-interface. Standard data limits, i.e. the data limit that the sub-interface is actually set. The encapsulation volume is the part of the volume that needs to be added to the terminal message after the sub-interface encapsulates the terminal message. For example, the encapsulation volume may include the length of the GTP-U encapsulation header, the VxVLAN header length, GRE header overhead, and the like.
It can be understood that if the volume of a terminal before the packet is encapsulated is originally smaller than the standard data limit of the subinterface, but the volume of the terminal after the encapsulation is increased to be larger than the standard data limit of the subinterface, the terminal still cannot directly pass through the subinterface. It is obviously inaccurate if standard data limits are used as references for setting the data limits of the terminal device. The difference between the standard data limit and the package volume is thus determined in this embodiment as the first data limit of the sub-interface. This means that if the volume of the terminal message entering the sub-interface before encapsulation is not greater than the first data limit, the volume of the terminal message after encapsulation is still not greater than the corresponding standard data limit, and the terminal message can directly pass through the sub-interface. In this embodiment, the first data limit value will therefore be used as a reference for setting the data limit value of the terminal device.
Step 202, determining a minimum data limit corresponding to the user plane network element according to the first data limit.
Step 203, determining a second data limit corresponding to the terminal device based on the minimum data limit.
The contents of steps 202 to 203 are substantially the same as those of the foregoing embodiments, and will not be repeated here. So far, in the embodiment, aiming at the situation that the user plane network element carries out the fragmentation processing, the setting of the data limit value of the terminal equipment is realized, so that the data limit value of the terminal equipment is matched with the data limit value of the user plane network element, and the communication efficiency is improved.
As shown in fig. 3, another embodiment of the data limit determination method according to the present invention is shown. The present embodiment specifically describes, on the basis of the foregoing embodiment, a case where a fragmentation process is performed on a network element node other than a user plane network element. In this embodiment, other network element nodes except the user plane network element are collectively called an intermediate network element. The method specifically comprises the following steps:
step 301, determining a first data limit value corresponding to the intermediate network element when the number of terminal messages subjected to the fragmentation processing by the intermediate network element reaches a second proportion threshold value.
In this embodiment, the user plane network element is still selected as the execution body. If the data limit value of the terminal equipment is larger than the data limit value of the intermediate network element, the volume of the terminal message after the fragmentation processing of the terminal equipment can be equal to the data limit value of the terminal equipment, and the terminal message cannot directly pass through the intermediate network element and needs to be fragmented again in the intermediate network element. At this time, a decrease in communication efficiency may be caused. The terminal message fragmented by the intermediate network element can generally be forwarded to the user plane network element directly through the terminal device, via the terminal device. Therefore, the user plane network element can judge whether the received terminal message is fragmented by the intermediate network element or not by the following way:
and judging whether the volume of the first sub-message in the terminal message is smaller than the data limit value of the terminal equipment. The first sub-message is a first segment message obtained after the fragmentation processing of the original message (communication message before the fragmentation processing).
For example, assume that the data limit of a certain intermediate network element is 1000Bytes, and the data limit of the terminal device is 1200Bytes, i.e. the data limit of the terminal device is larger than the data limit of the intermediate network element. If the volume of a certain original message is 1500Bytes, the original message needs to be fragmented whether the original message passes through the intermediate network element or the terminal equipment.
If the original message passes through the intermediate network element, the original message is fragmented into 2 sub-messages. The volume of the first sub-packet is necessarily equal to the data limit of the intermediate network element, i.e. 1000Bytes, and the volume of the other sub-packet (which may be called the second sub-packet) is 500Bytes.
Similarly, if the original message passes through the terminal device, the original message will be fragmented into 2 sub-messages. The volume of the first sub-message is necessarily equal to the data limit of the terminal device, i.e. 1200Bytes, and the volume of the other sub-message (which may be called the second sub-message) is 300Bytes.
It can be presumed that if the volume of the first sub-packet received by the ue is equal to the data limit of the terminal device, the first sub-packet is obtained by the fragmentation processing of the terminal device with a high probability. Otherwise, if the volume of the first sub-packet received by the user plane network element is smaller than the data limit of the terminal device, the first sub-packet cannot be obtained by the terminal device in a slicing manner, and should be considered to be obtained by a certain intermediate network element in a slicing manner.
Based on this determination, in this embodiment, the total number of terminal messages received by the user plane network element is a2 in a specific time range, and the number of terminal messages obtained by the intermediate network element fragmentation processing is b2, so that the ratio of b2 to a2 is the duty ratio of the intermediate network element fragmentation processing terminal messages. When the ratio reaches a preset second ratio threshold, namely the number of times of the fragmentation processing of the intermediate network element is considered to be excessive, the data limit value of the terminal equipment is not matched with the data limit value of the intermediate network element, and the data limit value of the terminal equipment needs to be adjusted. Thus, a first data limit value corresponding to the intermediate network element will be further determined.
Step 302, determining a minimum data limit corresponding to the intermediate network element according to the first data limit.
Step 303, determining a second data limit corresponding to the terminal device based on the minimum data limit.
The contents of steps 302 to 303 are substantially the same as those of the foregoing embodiments, and a description thereof will not be repeated. So far, in the embodiment, aiming at the situation that the middle network element performs the fragmentation processing, the setting of the data limit value of the terminal equipment is realized, so that the data limit value of the terminal equipment is matched with the data limit value of the middle network element, and the communication efficiency is improved.
