Problems solved by technology

[0006] 1. In the IPv4 stage, IP address resources are limited, especially in the case of large-scale applications, it will consume a lot of IP address resources, causing difficulties for operators in address allocation and networking
[0007] 2. There are too many IP addresses of the equipment, causing maintenance troubles

Embodiment Construction

[0024] The present invention adopts the floating IP address binding method, and its realization principle is: a peer-to-peer connection only uses one IP address, and among multiple network card adapters, only one is the main work, and the others are used as backup, although physically Connected to the network, but no IP address is bound to it, and it is idle. Through this floating IP method, the signaling access gateway has only one network address externally, and the external application server does not need to care about which network card adapter it communicates with, such as image 3 As shown, it is a schematic diagram of a signaling access gateway network where two network card adapters share one IP address. In the figure, the signaling access gateway has two network card adapters, NIC_1 and NIC_2, and communicates with the network card adapter NIC_0 (its IP address is IP_0) in the application server through a floating IP address IP_1.

Abstract

Said invention provides a method for enhancing data communication reliability by float IP address. It contains configuring at least two network cards network card adapter in signalling access gateway, binding float IP address information address information with said network card adapter, originating connection to application server end, to make data communication, if communication disorder occurred, deleting float IP address information from currently binding ' s network card adapter at the same time selecting another network card adapter, binding float IP address information to currently selected network card adapter continue data communication. Said invention reduces occupying limited IP address resource and enhances data communication reliability.

Description

technical field [0001] The invention relates to network data communication based on TCP / IP communication, in particular to a method for improving data communication reliability by using a floating IP address between an intelligent network, a short message center, an HLR signaling access gateway and an application server. Background technique [0002] A TCP / IP connection is usually used for communication between the signaling access gateway and the application server. The signaling access gateway is responsible for converting the MTP message of the narrowband No.7 signaling network or the M3UA protocol interface of the broadband SIGTRAN into a TCAP message. The specific connection diagram is as follows figure 1 As shown, and then sent to the application server through the TCP / IP network, such as figure 2 As shown, the hardware connecting the two is usually a network card adapter (NIC). [0003] From the perspective of networking, the position of the signaling access gatewa...
