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.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
In order to solve the problem that the user use is affected due to the fact that the abnormal connection between the terminal device and the data network cannot be detected in time in the prior art, the invention provides a method for detecting the connection state of the data network.
For convenience of description, the following description will be made of an embodiment of the method taking as an example that an execution subject of the method is a terminal device capable of executing the method. It is understood that the implementation of the method by the terminal device is only an exemplary illustration, and should not be construed as a limitation of the method.
Specifically, the method for detecting the connection state of the data network provided by the invention comprises the following steps: firstly, obtaining RTT round trip time of at least one TCP transmission control protocol connection service of the terminal equipment; and then, determining the connection state of the data network of the terminal equipment according to the RTT of at least one TCP connection service of the terminal equipment.
In the embodiment of the invention, the RTT of at least one TCP connection service in the terminal equipment can be obtained, and the connection state of the data network of the terminal equipment can be determined according to the RTT of at least one TCP connection service of the terminal equipment. Therefore, when at least one TCP connection service exists in the terminal equipment, whether the connection state of the data network of the terminal equipment is abnormal or not can be determined by acquiring the RTT duration of the TCP connection services. If it is determined that the connection of the data network of the terminal device is abnormal, the terminal device may take some measures in time to recover the connection between the terminal device and the data network, for example, the connection between the terminal device and the data network may be recovered by restarting a data network switch or performing measures such as data network re-registration.
The following describes in detail an implementation process of the method with reference to a schematic flow chart of a specific implementation of the method for detecting a connection state of a data network shown in fig. 1, and includes:
as described in the background art, in the prior art, a terminal device often can execute a plurality of TCP connection services at the same time, for example, when a user browses a web page through the terminal device, all applications such as a chat application, a map application, and a shopping application in the terminal device may run in the background, if the connection between the terminal device and a data network is abnormal at this time, the user may not browse the web page normally, and other applications such as the chat application, the map application, and the shopping application in the terminal device may not receive and update data in time, so that the use experience of the user may be affected.
In order to solve the problem, the embodiment of the present invention may detect a connection state of a data network of a terminal device, that is, a connection state of a Long Term Evolution (LTE) network of the terminal device, by obtaining an RTT duration of at least one TCP connection service in the terminal device, and if it is determined that the connection state of the data network of the terminal device is abnormal, the terminal device may reestablish a connection between the terminal device and the data network based on the connection state between the terminal device and the data network, so that a user can normally use an application in the terminal device.
Optionally, determining the connection state of the data network of the terminal device according to the RTT of at least one TCP connection service of the terminal device may include the following two cases:
in the first case, if the RTTs of the M TCP connection services of the terminal device are all greater than or equal to the first threshold, it may be determined that the data network connection of the terminal device is abnormal;
assuming that a terminal device executes a number of TCP connection services including browsing a webpage, chatting, paying, subscribing and the like at the same time within a preset time period, after obtaining the RTTs of the a TCP connection services, if it is determined that the RTTs of M TCP connection services existing in the a TCP connection services are all greater than or equal to a first threshold, it may be determined that the connection of the data network of the terminal device is abnormal, where M is less than or equal to a.
Optionally, when determining the data network connection state of the terminal device, in order to determine the data network connection state of the terminal device more accurately, the data network connection state of the terminal device may also be determined based on RTTs of consecutive M TCP connection services of the terminal device, that is, if the RTTs of consecutive M TCP connection services of the terminal device are all greater than or equal to the first threshold, it may be determined that the data network connection of the terminal device is abnormal.
In the second case, if the average RTT round trip delay of the RTTs of the N TCP connection services of the terminal device is greater than or equal to the second threshold, it may be determined that the data network connection of the terminal device is abnormal.
Continuously assuming that the terminal device simultaneously executes a number of TCP connection services within a preset time period, including a number of TCP connection services such as web page browsing, chatting, payment, subscription, and the like, after obtaining the RTTs of the a number of TCP connection services, if it is determined that the average value of the RTTs of N number of TCP connection services exists in the a number of TCP connection services is greater than or equal to a preset threshold, it may be determined that the connection of the data network of the terminal device is abnormal, where N is less than or equal to a.
Optionally, when determining the data network connection state of the terminal device, in order to determine the data network connection state of the terminal device more accurately, the data network connection state of the terminal device may also be determined based on an average value of RTTs of consecutive N TCP connection services of the terminal device, and if an average RTT round trip delay of RTTs of consecutive N TCP connection services of the terminal device is greater than or equal to a second threshold, it may be determined that the data network connection of the terminal device is abnormal.
Optionally, in order to enable the data network connection state of the terminal device to be recovered to normal as soon as possible so as to meet the use requirement of the user, in the embodiment of the present invention, after the data network connection of the terminal device is determined to be abnormal, a connection may be reestablished with the network side device or the data network switch in the terminal device may be restarted so as to reestablish a connection with the data network.
Optionally, after determining that the data network connection of the terminal device is abnormal, since the connection state between the terminal device and the data network may include a disconnected state and an un-disconnected state, in order to reestablish the connection between the terminal device and the data network according to the connection state between the terminal device and the data network, the connection state between the terminal device and the data network may also be acquired, and if the mobile data of the terminal device is in the disconnected state, the connection may be reestablished with the network-side device or the data network switch in the terminal device may be restarted to reestablish the connection with the data network.
For example, when the terminal device is in a space where signals of an elevator, a basement or other data networks are weak or even no signals of the data networks, the connection state between the terminal device and the data networks is a disconnected state, and at this time, in order to reestablish the connection between the terminal device and the data networks as soon as possible, the terminal device may restart the terminal device or switch a flight model to reestablish the connection with the network-side device every preset time period, or may restart the data network switch to send a connection request to the data networks, thereby reestablishing the connection with the data networks.
Optionally, when the connection state between the terminal device and the data network is not disconnected, the connection may be reestablished with the network side device or the data network switch in the terminal device may be restarted to reestablish the connection with the data network. Specifically, the method comprises the following steps:
in the first mode, connection is reestablished with network side equipment so as to reestablish connection with a data network;
in practical application, the terminal device may be restarted, or the "flight mode" in the terminal device is started first and then closed, so as to reestablish connection with the network-side device and reestablish connection with the data network.
In a second way, the data network switch in the terminal device may be restarted to reestablish a connection with the data network.

In the embodiment of the invention, the RTT of at least one TCP connection service in the terminal equipment can be obtained, and the connection state of the data network of the terminal equipment can be determined according to the RTT of at least one TCP connection service of the terminal equipment. Therefore, when at least one TCP connection service exists in the terminal equipment, whether the connection state of the data network of the terminal equipment is abnormal or not can be determined by acquiring the RTT duration of the TCP connection services. If it is determined that the connection of the data network of the terminal device is abnormal, the terminal device may take some measures in time to recover the connection between the terminal device and the data network, for example, the connection between the terminal device and the data network may be recovered by restarting a data network switch or performing measures such as data network re-registration.

Therefore, when at least one TCP connection service exists in the terminal equipment, whether the connection state of the data network of the terminal equipment is abnormal or not can be determined by acquiring the RTT duration of the TCP connection services. If it is determined that the connection of the data network of the terminal device is abnormal, the terminal device may take some measures in time to recover the connection between the terminal device and the data network, for example, the connection between the terminal device and the data network may be recovered by restarting a data network switch or performing measures such as data network re-registration.
