Problems solved by technology

[0010] In the prior art, when the interface of the gateway device connected to the external data network fails, if the user continues to be connected, it will appear to the access network and the user that the access to the gateway device is successful, but the user cannot use the service normally.
Since the gateway device appears to be working normally to the access network device, the access network will also send the user's service requests to the gateway device, and these requests can still be normally accessed by the gateway device, but the user still cannot use the service, so the gateway device The redundant backup mechanism will be ineffective and cannot bring higher reliability to the network

Embodiment Construction

[0026] Embodiment 1 of the present invention provides a linkage processing method, as shown in FIG. 2 , including the following steps:

[0027] Step s201, detecting the state of the interface of the gateway device connected to the external data network, and determining whether there is a failure. For example, the gateway device uses the BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection) mechanism, and the gateway device determines whether the interface is available by detecting the link state between the router and the next-hop router; or the gateway device directly detects the state of the interface, such as Detect the status of the Ethernet interface. If the interface fails, the gateway device will perceive it; or the gateway device detects a server on the external data network through the Ping message, and if it receives a response, it indicates that the interface status is normal. Certainly, other connection / device state detection mechanisms may a...

Abstract

The invention discloses a linkage processing method which comprises the following steps: checking a port of gateway equipment in connection with an outer data network and deciding linkage action according to the checking result of the port when the port has faults; executing corresponding linkage action for the accessing request of users. The invention discloses a gateway equipment with a gateway which can retransmit the inquiries from the accessing network to a backup gateway equipment or refuse inquiries through a pre-arranged communicating relation when the port of the gateway equipment in connection with the outer data network in order to ensure that the redundant backup mechanism works normally in time.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a linkage processing method and device. Background technique [0002] The data communication network in the prior art is shown in Figure 1. The gateway device accessing the network is used as the handover point between the access network and the external data network, and generally has at least two or more interfaces, such as the interface connecting the gateway device to the access network and the The gateway device is connected to the interface of the external data network. The gateway device processes the session establishment request of the user on the access network, and establishes a communication session for the user to communicate with the external data network. [0003] For example, the GGSN (Gateway GPRS Support Node) in the UMTS (Universal Mobile Telephone Service, Universal Mobile Communication System) network is located at the junction of the UMTS...
