Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
At present, many internet applications support a two-way connection mode, that is, a client and a server simultaneously adopt different physical paths to establish a data connection relationship, so as to obtain a larger bandwidth and higher reliability.
Meanwhile, the mobile terminal may be connected to a plurality of different networks, for example, two different mobile communication networks at the same time. Therefore, the mobile terminal can be connected to the server through two data connections of different physical paths respectively. The commonly used connection technology is MPTCP (Multi-Path TCP Protocol) technology.
The current mobile terminal can be connected to two mutually independent networks simultaneously and establish a data connection with the correspondent node via the two networks, respectively, the data connection corresponding to one session in each of the two networks. The correspondent node may consider that the two sessions point to the same data flow, that is, each of the two networks takes on a part of traffic in the same data flow, which refers to the use of bandwidth resources.
However, since the two networks to which the mobile terminal is connected are independent of each other, the bandwidth resources of the two networks cannot be shared. Therefore, when the bandwidth resource provided by one of the networks for the mobile terminal is reduced, the other network cannot provide corresponding bandwidth resource compensation for the mobile terminal in time, which results in the reduction of the total bandwidth resource currently obtained by the mobile terminal, and even affects the stability of the data connection of the mobile terminal, thereby causing the session quality between the mobile terminal and the opposite communication terminal to be poor.
In order to solve the foregoing problems, an embodiment of the present invention provides a method for adjusting bandwidth resources, which is applied to a first network system. The mobile terminal establishes a first session with the correspondent node based on the first bandwidth resource provided by the first network system, and establishes a second session with the correspondent node based on the second bandwidth resource provided by the second network system. That is, the mobile terminal establishes a multi-path connection with the correspondent node through the first network system and the second network system, where the total bandwidth resource amount is the sum of the first resource amount and the second resource amount, and the first network system and the second network system are different mobile communication network systems.

step S101, in response to that the predicted available resource amount of the bandwidth resource of the first network system is smaller than a first resource amount corresponding to the first bandwidth resource, determining a pre-adjusted resource amount for the mobile terminal based on the first resource amount.
The predicted available resource amount refers to the resource amount of the bandwidth resource which the first network system can predict to provide for the mobile terminal at the current position, and the current position is the current position of the mobile terminal. The first amount of resources is an amount of resources of a first bandwidth resource currently provided by the first network system for the mobile terminal.
In one embodiment, the pre-adjusted amount of resources is a difference between the first amount of resources and an amount of resources expected to be available.
In one embodiment, before the first network system determining the pre-adjusted amount of resources for the mobile terminal based on the first amount of resources in response to the predicted amount of available resources of the bandwidth resources of the first network system being less than the first amount of resources, the method further comprises: and receiving a second session identifier corresponding to a second session sent by the mobile terminal, and storing the second session identifier and the terminal identifier of the mobile terminal in a correlation manner.
Step S102, sending the bandwidth resource request information to the second network system, so that the second network system adjusts the resource amount of the bandwidth resource of the second session corresponding to the second session identifier from the second resource amount to a third resource amount in response to the bandwidth resource request information.
The bandwidth resource request information comprises a preset resource amount and a pre-stored second session identifier corresponding to the second session. The third resource amount is the sum of the second resource amount and the pre-adjusted resource amount.
In one embodiment, the step of the first network system transmitting the bandwidth resource request information to the second network system (step S102 above) includes: and determining a second control plane network element corresponding to the second session identifier in the second network system based on the second session identifier, and sending the bandwidth resource request information to the second control plane network element through the first control plane network element.
Wherein, under the condition that the first network system is 5G, the first control plane network element is a Session Management Function (SMF); when the first network system is 4G, the first control plane network element is a Packet data network Gateway (PGW-C) control plane. Similarly, when the second network system is 5G, the second control plane network element is SMF; and under the condition that the second network system is 4G, the second control plane network element is PGW-C.

Wherein the fourth resource amount is a difference between the first resource amount and the pre-adjusted resource amount.

However, due to the influence of factors such as the location change of the mobile terminal, the different coverage areas of different mobile communication networks, and the signal strength of the same mobile communication network in different coverage areas, the mobile terminal may encounter the situation that the bandwidth resources of the connected first network system are insufficient in the process of using the service, which may cause the service quality to be degraded (for example, watching a low-bit rate live video) because the mobile terminal can only obtain a low bandwidth, or even cause the whole data link of the mobile terminal to be disconnected, and reduce the user experience. By the bandwidth resource adjusting method provided by the embodiment of the invention, the first network system and the second network system can provide stable bandwidth resources for the mobile terminal together, the stability of data connection of the mobile terminal is improved, and the user experience is ensured.
