GGSN IP Address Assignment Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of network management for mobile operators increase due to the need for frequent updates in configuration parameters for new Access Point Names (APNs) as mobile operators develop diverse services, and users face complexity in changing APN configurations for different services, affecting the performance of Gateway GPRS Support Nodes (GGSN) during IP address assignment.
Innovation Solution
A method and apparatus that simplify the IP address assignment process by selecting a service with a different APN from the service list and determining if a same VPN exists, allowing the GGSN to activate a service PDP context using a default PDP context IP address, thereby avoiding the need for reassignment using various IP address assignment methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile operators create more APNs to support diversified services, then service coverage and versatility are improved, but network management complexity and costs increase
Solution Approach 1:
The patent implements a universal IP address pool that serves multiple APNs and services. Instead of creating separate IP address management systems for each APN, a single IP address pool is shared across all services, allowing one system to perform multiple functions and support diverse services without increasing management complexity
Solution Approach 2:
The patent merges the IP address management of multiple APNs into a single unified IP address pool. By combining previously separate IP address allocation systems into one shared resource, the patent reduces the number of configuration parameters and simplifies network management while maintaining support for multiple services
2Adaptability or versatility
If users change APN configuration for different services, then service access capability is improved, but user operation complexity increases
Solution Approach 1:
The system automatically selects and allocates IP addresses from the appropriate pool based on the service type and APN, without requiring user intervention. The network infrastructure itself performs the service of matching services to IP address pools, eliminating the need for users to manually configure or change settings
3Adaptability or versatility
If GGSN uses different IP address assignment methods for different services, then service-specific IP address allocation is improved, but GGSN performance deteriorates
Solution Approach 1:
The patent changes the parameter of IP address pool selection from a dynamic, service-specific assignment to a static, pre-configured mapping. Each service is assigned a specific IP address pool in advance, and the GGSN simply selects the corresponding pool based on service identification, avoiding complex real-time decisions and improving processing performance

AI summary
Disclosed in embodiments of the present invention are a method and an apparatus for assigning an IP address, so as to simplify the process in which a GGSN assigns an IP address, and improve performance of the GGSN. The method in the embodiment of the present invention includes: receiving a request message initiated by the GGSN for creating a service PDP context for a user; obtaining a service list of the user; selecting a service with a different APN out of services recorded in the service; determining whether a same VPN exists in VPNs corresponding to the services with the different APN, and if not, sending a response message of creating a service PDP context for a user to the SGSN, and activating a service PDP context by using an IP address of a default PDP context as an IP address of the service PDP context.
