HLR Dual Registration for Seamless Circuit-Packet Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile stations must traditionally de-register from circuit-switched networks and re-register with packet-switched networks, disrupting service and requiring complex re-registration processes, which is inefficient as the industry transitions towards packet-switched networks.
Innovation Solution
A system and method for dual registration in a home location register (HLR) that allows simultaneous circuit-switched and packet-switched registration, enabling a mobile station to be serviced in either or both domains by maintaining concurrent registrations with both types of networks and routing service requests based on configured routing rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile station de-registers from the circuit-switched network and re-registers with the packet-switched network, then the mobile station can access packet-switched network services, but service continuity is disrupted and the re-registration process becomes complex
Solution Approach 1:
The patent segments the registration process by maintaining separate registration contexts for circuit-switched and packet-switched networks within the HLR. This allows independent registration management for each network type, enabling the mobile station to be registered with both networks simultaneously without requiring de-registration from one network to register with another, thus preserving service continuity while expanding network access capability.
2Adaptability or versatility
If traditional single registration is used, then the registration process is simple, but the mobile station cannot simultaneously access both circuit-switched and packet-switched networks
Solution Approach 1:
The HLR is enhanced with multi-functionality to serve both circuit-switched and packet-switched networks simultaneously. The system introduces a unified registration management mechanism that handles both network types through a single HLR entity, maintaining separate serving node information for each network type while using a common registration framework. This universal approach enables dual network access without proportionally increasing overall system complexity.
3Productivity
If re-registration is required for network transition, then network operators can control service routing, but the process is time-consuming and inefficient
Solution Approach 1:
The patent implements preliminary action by pre-configuring routing rules in the HLR that determine service routing based on the mobile station's registration state and network conditions. The system prepares multiple serving node configurations in advance and uses them automatically during service setup, eliminating the need for time-consuming re-registration processes while maintaining operator control over service routing through configurable policies.

AI summary
A method and system for managing services for a mobile station by a network service provider includes receiving a first registration request associated with the mobile station at a registration node, registering a first switching node as a first serving node for access by the mobile station to a first network, receiving a second registration request associated with the mobile station at the registration node, and registering a second switching node as a second serving node for access by the mobile station to a second network. The first serving node and the second serving node are concurrently maintained. The method further includes receiving a service request for providing a network service to the mobile station, and routing the service request to either the first switching node or the second switching node in accordance with routing rules associated with the mobile station configured by the network service provider.
