Conversion method between an main communicational equipment and a spare communicational equipment, the communicational equipments and a service request equipment

Abstract

A main / backup switching method between communication devices, a communication device, system and a service request device are provided in the embodiments of the prevent invention. Wherein the method includes: a main / backup switching negotiation request is received which is transmitted by a main communication device and carries a fault information, wherein the fault information includes the service load of the main communication device and the amount of the current loss; the amount of the anticipative service loss of a backup communication device after switching is determined, and when the amount of the anticipative service loss is less than the amount of the current loss, it is determined that the main / backup switching is required; a main-backup switching instruction is transmitted to the service request device; the main-backup switching instruction instructs the service request device to switch its signaling communication pointer from the main signaling interaction interface address to the backup signaling interaction interface address; the service provided by the main communication device is taken over and borne. The embodiments of the prevent invention reduce the probability of the user service interruption during the main / backup switching between the communication devices.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an active / standby switching method between communication devices, a communication device and system, and a service request device. Background technique [0002] With the vigorous development of the mobile Internet, more and more people enjoy various services provided by the mobile Internet through smart terminals, such as: web browsing, VoIP (Voice over Internet Protocol), video, social networking, instant messaging, etc. The packet gateway device provides a series of important services when users access the Internet, such as: assigning IP addresses to terminals, authentication, billing, and service control. Since packet gateway devices and other types of communication devices are located in important network locations and have the ability to serve a large number of users, communication systems have high requirements on the reliability of these devices.

AI Technical Summary

Problems solved by technology

[0004] In the process of practicing the existing technology, the inventor found that the "active-active" phenomenon will cause abnormal network behaviors, such as address conflicts, routing conflicts, etc., which will cause abnormal judgments of the surrounding network elements of the gateway device. Whether the source address or destination address points to the main gateway device or the backup gateway device, so the surrounding network elements may deactivate a large number of online users, causing user business interruption and increasing user business loss
