Group Bearer Allocation for Multi-Group Network Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing network resources efficiently for devices belonging to multiple groups in a wireless communication system is challenging, as existing methods require separate APNs and PDN connections, leading to difficulties in resource management and increased consumption.
Innovation Solution
A method and apparatus for setting a network connection that involves receiving a packet filter from user equipment, obtaining a group identifier, creating a group bearer if it does not exist, and allocating communication through the created group bearer, allowing for shared resource usage across multiple groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate APNs and PDN connections are created for each group, then group services can be provided, but network resource management becomes difficult and resource consumption increases
Solution Approach 1:
The patent merges multiple group services into a single APN by introducing a group identifier field in the PDN connectivity request. Instead of creating separate APNs for each group, the system allows multiple groups to share one APN while distinguishing them through group identifiers, thereby reducing APN management complexity while maintaining group service differentiation
Solution Approach 2:
The single APN is designed to serve multiple groups simultaneously by incorporating group identifier matching functionality. The APN can handle requests from different groups by matching the group identifier in the request against stored group information, making the APN universal for multiple group services rather than dedicated to a single group
2Adaptability or versatility
If separate APNs are created for each group, then group services can be provided, but network resource consumption increases
Solution Approach 1:
The patent combines multiple group bearers into a single APN connection, reducing the total number of PDN connections required. By sharing the APN infrastructure across multiple groups and using group identifiers to route traffic appropriately, the system reduces redundant network resources while maintaining the ability to provide differentiated services to each group
3Adaptability or versatility
If multiple PDN connections are established for a device belonging to multiple groups, then all group services can be accessed, but IP address allocation becomes complex
Solution Approach 1:
The patent merges multiple group service accesses into a single PDN connection by including group identifier information in the PDN connectivity request. The network entity uses this group identifier to identify the appropriate group bearer and allocate IP addresses accordingly, allowing a device to access multiple group services through one connection rather than requiring separate PDN connections for each group
Solution Approach 2:
The group identifier acts as an intermediary that enables the network entity to distinguish between different groups within a single PDN connection. By matching the group identifier against stored group information, the system can route traffic to the appropriate group bearer and manage IP address allocation without requiring separate PDN connections for each group

AI summary
The present invention relates a method and apparatus for setting a group-based connection. A connection setting method for a network entity according to one embodiment of the present invention includes the steps of: receiving a request including at least one packet filter from a terminal; obtaining a group identifier corresponding to the packet filter by using the packet filter; when a group bearer corresponding to the group identifier does not exist, generating a group bearer corresponding to the group identifier; and performing allocation such that communication corresponding to the request is performed through the generated group bearer. According to one embodiment of the present invention, a service can be efficiently provided to a terminal.
