GGSN capacity overload emergency safeguard method based on IP address pool

Abstract

The present invention provides a method for guaranteeing GGSN capability at a condition that the load of network operation capacity is high. The method comprises the following steps: measuring a safety operation capacity of GGSN device, the safety operation capacity is a maximum capacity limit which can be obtained by the GGSN device; setting a safety threshold as a base line of the GGSN device based on the safety operation capacity; restricting the capacity of an IP address pool in the safety threshold to guarantee that the number of PDP text subscriber in the GGSN device is in the base line of safety operation; and executing full-service testing after the configuration operation to guarantee the rightness of data modification. The method according to the invention actively restricts the capacity of GGSN access through adjusting the magnitude of capacity of IP address pool at the condition that the load of network operation capacity is high. The method according to the invention guarantees that the device can work normally at the condition of high load and guarantees the service quality of access subscriber.

Description

technical field [0001] The present invention relates to the grouping domain of the second generation and the third generation mobile communication network system, and specifically relates to a method for GGSN capacity overload emergency protection. Background technique [0002] GPRS (General Packet Radio Service, General Packet Radio Service) is a second-generation mobile communication network system based on packet switching, and related standards are formulated by ETSI (European Telecommunications Standards Institute, European Telecommunications Standards Institute). figure 1 Shown is the network architecture of GPRS. In the third generation mobile communication system, GPRS has evolved into a UMTS PS (Universal Mobile Telecommunications System Packet Switch, Universal Mobile Telecommunications System Packet Switching) domain. figure 2 Shown is the network architecture of the third generation mobile communication system UMTS PS domain. The above two network architecture...

Problems solved by technology

[0029] Due to the lack of effective GGSN emergency support technology in the case of network operation capacity overload and high load, in the existing technology, there is often nothing that can be done for the sudden increase of user access requests, and the resources of the equipment can only be exhausted. The user service quality becomes very low, even when the device is restarted, the user service quality can be eased

In addition, some equipment manufacturers currently provide the option to limit the maximum number of PDP activations. Due to the different implementation principles and inconsistent configurations of each manufacturer, it is difficult to widely promote it on the entire network. For operators, there are many different manufacturers on the entire network. , it is necessary to adopt the technology applicable to the entire network to provide emergency protection for the GGSN capacity of the entire network
