Abstract
Embodiments of the present invention provide a fault detection method. The method includes discovering that a fault occurs in a DNS server or a service server related to a UE. The method also includes performing, by a gateway, fault detection on the DNS server or the service server. The method also includes, after the fault is rectified, instructing the UE to establish a connection to the DNS server or the service server.
Claims20
An apparatus, comprising:
- a processor, configured to:
- discover that that a fault occurs in a server, wherein the server is a domain name system (DNS) server or a service server related to a user equipment (UE);
- and
- detect whether the fault is rectified;
- and
- a transmitter, configured to:
- instruct the UE to stop a current DNS query or a current Transmission Control Protocol (TCP) connection attempt;
- and
- after the fault occurring in the server is rectified, transmit a notification message to the UE, wherein the notification message instructs the UE to establish a connection to the server.
A non-transitory computer-readable media storing computer instructions for execution by one or more processors, wherein the computer instructions instruct the one or more processors to:
- discover that a fault occurs in a server, where the server is a domain name system (DNS) server or a service server related to a user equipment (UE);
- request a gateway to detect whether the fault is rectified for the UE;
- receive a notification message from the gateway after the fault is rectified;
- and
- establish a connection to the server in response to receiving the notification message.
A system, comprising:
- a user equipment (UE), configured to:
- discover that a fault occurs in a server, wherein the server is a domain name system (DNS) server or a service server related to the UE;
- and
- send a request to a gateway to request the gateway to detect, for the UE, whether the fault is rectified;
- and
- the gateway, configured to:
- receive the request from the UE;
- instruct the UE to stop a current DNS query or a current Transmission Control Protocol (TCP) connection attempt;
- detect that the fault occurring in the server has been rectified;
- and
- after the fault is rectified, transmit a notification message to the UE;
- wherein the UE is further configured to establish a connection to the server in response to the receiving the notification message from the gateway.
