Background
In an IPv 6-based protocol data session, it is common to statically configure the data limit of a terminal device by using some network element nodes, that is, determine the maximum size of an uplink packet and a downlink packet passing through the terminal device. Similarly, corresponding data limit values, that is, the maximum sizes of uplink and downlink messages passing through the terminal device, also exist on each network element node in the protocol data session.
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, the message passing through the terminal device may not directly pass through the network element node due to a large size, and 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 obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an IPv 6-based Protocol Data Session, that is, a PDU (Protocol Data Unit) Session, a terminal device and a network element node are both provided with respective Data limit values (that is, MTU, Maximum Transmission Unit). The data limit is used to determine the maximum volume of the communication packet that can pass through the terminal device and the network element node. If the volume of the communication message needing to pass through is larger than the data limit value, the terminal equipment and the network element node perform fragmentation processing on the communication message.
The network element nodes in the protocol data Session may include a Session Management network element (SMF), a User Plane network element (UPF), and the like. Currently, the data limit of the terminal equipment is usually configured statically by using an SMF network element.
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, the message passing through the terminal device cannot directly pass through the network element node due to its large volume, and the fragmentation processing has to be performed at the network element node.
Based on the above, it can be understood 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 of the terminal device is too large, a large number of communication messages are fragmented at various network element nodes, which results in reduced communication efficiency. If the data limit of the terminal device is too small, the terminal device has to perform excessive fragmentation processing on the original communication packet, which also causes a decrease in communication efficiency. Therefore, it is preferable that the data limit of the terminal device is closer to the data limit of the network element node, and at this time, the number of times of the fragmentation occurs is small, and the overall communication efficiency of the protocol data session is high.
However, in the prior art, the data limit configuration of the terminal device by the SMF network element belongs to a static configuration. The static configuration means that the data limit of the terminal device cannot be adaptively adjusted according to the specific situation of the network element node, that is, the data limit of the terminal device cannot reach a state closer to the data limit of the network element node in real time. Therefore, the problem of communication efficiency reduction caused by fragmentation processing of a large number of messages at a network element node cannot be solved. The prior art lacks a solution for dynamically configuring data limit values of a terminal device.
Therefore, embodiments of the present invention will provide a data limit determination method to solve at least the above technical problems in the prior art. In this embodiment, the main 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:
In this embodiment, the network element node generally refers 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 subject of this embodiment is specifically a user plane network element in a network element node. That is, in this embodiment, dynamic configuration of the data limit value of the terminal device is 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 packet passing through the terminal device can be defined as a terminal packet. Specifically, the terminal message may be a communication message directly sent by the terminal device as the sending end. Or, the terminal packet may also be a communication packet forwarded by the terminal device as a relay node from another network element node. Based on the data limit of the network element node, the terminal packet may be fragmented at each network element node, or may not be fragmented.
In this embodiment, whether the terminal packet meets the preset condition is determined according to the actual situation of the network element node for the terminal packet fragmentation processing. For example, the number of all terminal messages received by the user plane network element may be determined within a specific time range; and determining the number of the terminal messages subjected to fragmentation processing. And when the ratio of the number of the terminal messages subjected to fragmentation processing to the number of all the terminal messages reaches a specific threshold value, the terminal messages subjected to fragmentation processing by the network element node at the moment are considered to meet the preset conditions. That is, at this time, it may be considered that the number of times of the network element node performing the fragmentation processing is too large, and the communication efficiency is affected. That is, the data limit of the terminal device is not matched with the data limit of the network element node, and the data limit of the terminal device needs to be adjusted.
It should be noted that, the above network element node may include two specific cases for the terminal packet fragmentation processing. For example, the user plane network element itself may perform fragmentation processing on the terminal packet, and then the user plane network element determines whether the terminal packet percentage of its own fragmentation processing reaches a specific threshold. Or, the terminal message may be fragmented by other network element nodes except the user plane network element; the terminal message subjected to the fragmentation processing is forwarded to a user plane network element through terminal equipment; and then the user plane network element determines whether the proportion of the terminal messages processed by the node fragmentation of other network elements reaches a specific threshold value.
In both cases, whether the user plane network element or other network element nodes need to perform fragmentation processing depends on the data limit value set by the user plane network element or other network element nodes. Therefore, on the premise that the terminal message subjected to the network element node fragmentation processing 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 is a data limit set by each network element node.
And step 102, determining a minimum data limit value corresponding to the network element node according to the first data limit value.
The first data limit values corresponding to the network element nodes are often different. It is understood that the smaller the data limit of a network element node, the more likely fragmentation occurs at the 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. Therefore, 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, and is used as a basis for subsequently setting the data limit value of the terminal device.
And 103, determining a second data limit value corresponding to the terminal equipment based on the minimum data limit value.
The minimum data limit represents the "narrowest" point in the communication channel in a protocol data session, where fragmentation occurs most frequently. If the data limit of the terminal device is close to the minimum data limit, it means that most of the terminal messages passing through the terminal device can directly pass through each network element node without further fragmentation processing. The overall communication efficiency of the protocol data session is high. In this embodiment, the second data limit corresponding to the terminal device is determined based on the minimum data limit. The second data limit is the data limit that is ultimately set for the terminal device in this embodiment.
In some cases, the minimum data limit value may be directly displayed as the second data to set the terminal device. In other cases, it is specified that the data limit of the terminal device is within a specific interval, i.e. there are a preset upper data limit (maximum) and a preset lower data limit (minimum). In this case, the second data limit corresponding to the terminal device may be determined based on the minimum data limit, the upper data limit, and the lower data limit. Specifically, if the minimum data limit is greater than the data limit upper limit, the data limit upper limit is set 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, then the minimum data limit is set to the second data limit.
It should be further noted that, in this embodiment, a specific manner of setting the second data limit value to the terminal device may be to adjust a data limit value parameter in the route advertisement message corresponding to the terminal device, so as to determine the second data limit value corresponding to the terminal device. The route advertisement message is an RA (Router advertisement) message in a protocol data session. And adjusting the data limit parameter in the route advertisement message may be to modify an MTU field in the route advertisement message, or to add the MTU field if the MTU field originally does not exist. And then the data limit value of the terminal equipment is set through the adjusted route notification message.
Routing notification messages sent to the terminal equipment by various network element nodes need to pass through a user plane network element. The user plane network element is a network element node which is most convenient for adjusting the data limit parameter in the route notification message in various different types of protocol data sessions (for example, in a 5G core network and a 5G access network). Therefore, in this embodiment, the user plane network element is selected as the execution subject, and dynamic setting of the data limit value for the terminal device can be implemented according to the overall situation of the protocol data session, so as to improve the communication efficiency.
It should be further noted that, in this embodiment, the method may be repeatedly executed periodically, 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 kept under an ideal condition. The specific period duration may be set according to the requirement, and 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, 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 without further fragmentation processing, and therefore the communication efficiency is improved.
Fig. 1 shows only a basic embodiment of the method of the present invention, and based on this, certain optimization and expansion can be performed, and other preferred embodiments of the method can also be obtained.
Fig. 2 shows another embodiment of the data limit determination method according to the present invention. On the basis of the foregoing embodiments, this embodiment specifically describes a situation in which the user plane network element performs fragmentation processing on itself. The method specifically comprises the following steps:
If the data limit of the terminal device is greater than the data limit of the user plane network element, the volume of the terminal message after being fragmented by the terminal device may be equal to the data limit of the terminal device, 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. This may result in a reduction in communication efficiency. In this embodiment, it can be calculated that the total number of the terminal messages received by the user plane network element in a specific time range is a1, where the number of the terminal messages subjected to the fragmentation processing is b1 when the volume is larger than the data limit value of the user plane network element, and thus the ratio of b1 to a1 is obtained as the occupation ratio of the terminal messages subjected to the fragmentation processing by the user plane network element. When the ratio reaches a preset first ratio threshold, the number of times of the user plane network element fragmentation processing is considered to be excessive, the data limit value of the terminal device is not matched with the data limit value of the user plane network element, and the data limit value of the terminal device 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 is further determined.
In practical cases, the user plane network element includes a plurality of sub-interfaces, which are respectively connected to other components in the protocol data session. Each subinterface has a respective first data limit. It should be noted that the first data limit value corresponding to the sub-interface is determined according to the standard data limit value of the sub-interface and the package volume corresponding to the sub-interface. The standard data limit, i.e. the data limit that the subinterface is actually set. And the encapsulation volume is the partial volume which 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 vxlan header length, the GRE header overhead, etc.
It can be understood that if the volume of a certain terminal before being encapsulated by a message is originally smaller than the standard data limit of the sub-interface, but the volume of the terminal after being encapsulated is increased by a part of the encapsulated volume, so that the terminal is larger than the standard data limit of the sub-interface, the terminal still cannot directly pass through the sub-interface. Therefore, if the standard data limit is used as a reference for setting the data limit of the terminal equipment, the standard data limit is obviously inaccurate. In this embodiment, the difference between the standard data limit and the package volume is thus determined as the first data limit of the subinterface. This means that if the volume of the terminal message entering the subinterface 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, i.e. the terminal message can pass through the subinterface directly. Therefore, in this embodiment, the first data limit value is used as a reference for setting the data limit value of the terminal device.
And 203, determining a second data limit value corresponding to the terminal device based on the minimum data limit value.
The contents of the above steps 202 to 203 are substantially the same as those of the above embodiments, and the description thereof will not be repeated. Therefore, in this embodiment, the setting of the data limit value of the terminal device is realized for the situation that the user plane network element performs fragmentation processing on itself, so that the data limit value of the terminal device is matched with the data limit value of the user plane network element, and the communication efficiency is improved.
Fig. 3 shows another embodiment of the data limit determination method according to the present invention. On the basis of the foregoing embodiment, this embodiment specifically describes a situation in which network element nodes other than the user plane network element perform fragmentation processing. In this embodiment, other network element nodes except the user plane network element are collectively referred to as an intermediate network element. The method specifically comprises the following steps:
In this embodiment, the user plane network element is still selected as the execution subject. If the data limit of the terminal device is greater than the data limit of the intermediate network element, the volume of the terminal message fragmented by the terminal device may be equal to the data limit of the terminal device, and the terminal message cannot directly pass through the intermediate network element, and needs to be fragmented again at the intermediate network element. This may result in a reduction in communication efficiency. However, the terminal packet fragmented by the intermediate network element can generally directly pass through the terminal device and be forwarded to the user plane network element via the terminal device. Therefore, the user plane network element can judge whether the received terminal message is processed by the intermediate network element in a fragmentation way as follows:
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 or not. The first sub-packet is a first segment of packet obtained after fragmentation processing of the original packet (the communication packet before fragmentation processing).
For example, suppose that the data limit of a certain intermediate network element is 1000Bytes, and the data limit of the terminal device is 1200Bytes, that is, the data limit of the terminal device is greater than the data limit of the intermediate network element. If the volume of a certain original message is 1500Bytes, it needs to be fragmented whether passing through the intermediate network element or the terminal device.
If the original message passes through the intermediate network element, the original message is fragmented into 2 sub-messages. The size of the first sub-packet is necessarily equal to the data limit of the intermediate network element, i.e. 1000Bytes, and the size of the other sub-packet (which may be referred to as the second sub-packet) is 500 Bytes.
Similarly, if the original message passes through the terminal device, it will also be fragmented into 2 sub-messages. The size of the first sub-packet is necessarily equal to the data limit of the terminal device, i.e. 1200Bytes, and the size of the other sub-packet (which may be referred to as the second sub-packet) is 300 Bytes.
Therefore, it can be presumed that, if the volume of the first sub-packet received by the user plane network element is equal to the data limit value of the terminal device, the first sub-packet has a high probability of being obtained through the terminal device fragmentation processing. On the contrary, 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 is generally not possible to be obtained through the fragmentation processing of the terminal device, but should be considered to be obtained through the fragmentation processing of some intermediate network element.
Based on this determination, in this embodiment, the total number of the terminal messages received by the user plane network element in a specific time range is a2, and the number of the terminal messages obtained through the fragmentation processing of the intermediate network element is b2, so that the ratio of b2 to a2 is the occupation ratio of the fragmentation processing of the intermediate network element. When the ratio reaches a preset second ratio threshold, that is, the number of times of fragmentation processing of the intermediate network element is considered to be excessive, the data limit value of the terminal device is not matched with the data limit value of the intermediate network element, and the data limit value of the terminal device needs to be adjusted. Thus, the first data limit value corresponding to the intermediate network element will be further determined.
And step 303, determining a second data limit value corresponding to the terminal device based on the minimum data limit value.
The contents of the above steps 302 to 303 are substantially the same as those of the above embodiments, and the description thereof will not be repeated. In this embodiment, in the case of performing fragmentation processing on the intermediate network element, setting of the data limit value of the terminal device is implemented, so that the data limit value of the terminal device is matched with the data limit value of the intermediate network element, and communication efficiency is improved.
