Heterogeneous Network Paging via MIH Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for paging mobile terminals in Idle Mode across heterogeneous networks require the terminal to awaken and establish IP connections, increasing load and resource usage, as they do not effectively consider Layer 2 characteristics for media-independent paging.
Innovation Solution
A method and system that allow paging messages and location updates to be transmitted across networks using different wireless standards, enabling the terminal to reconnect without awakening from Dormant Mode by using a secondary network with a different wireless standard for communication, leveraging the Media Independent Handover Service (MIH) architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal awakens from Dormant Mode to establish an IP connection for paging, then paging messages can be transmitted, but the load on the terminal and wireless resource usage increase
Solution Approach 1:
The patent introduces a network element as an intermediary that receives paging messages from the current network and forwards them to the terminal through a secondary network while the terminal remains in Dormant Mode. This mediator enables paging message transmission without requiring the terminal to awaken or establish an IP connection, thus resolving the contradiction between reliable paging and resource conservation.
2Loss of energy
If the terminal remains in Dormant Mode without establishing IP connection, then power consumption is reduced, but paging messages cannot be transmitted across heterogeneous networks
Solution Approach 1:
A network element acts as an intermediary that bridges the current network and the terminal's secondary network connection. It receives paging messages and forwards them through the secondary network without requiring the terminal to awaken from Dormant Mode, enabling reliable paging while maintaining low power consumption.
Solution Approach 2:
The patent segments the paging transmission process into two independent parts: the current network sends paging messages to the network element, and the network element separately forwards them to the terminal through the secondary network. This segmentation allows paging to occur without the terminal needing to establish an IP connection or awaken from Dormant Mode.
3Adaptability or versatility
If existing paging methods are used across heterogeneous networks, then paging can be implemented, but they do not effectively consider Layer 2 characteristics for media-independent paging
Solution Approach 1:
The network element serves as an intermediary that handles the complexity of heterogeneous network transitions. It receives paging messages from the current network, determines the appropriate secondary network for the terminal, and forwards the messages accordingly. This approach provides cross-network paging adaptability while avoiding the need for complex protocol modifications at the terminal level.
Data Source
AI summary
A method for paging a terminal device across heterogeneous networks, where networks using different wireless standards send paging messages and location management information, and thus the load terminal devices can be alleviated and wireless resources occupied can be reduced. The method includes: selecting, by a current network, another network to execute a paging procedure, when receiving user data and determining a corresponding communication interface of the terminal device in the current network to be in a Dormant Mode, where the another network uses wireless standards different from the current network; sending, by the another network, a paging message to the terminal device to enable the terminal device to reconnect to the current network. A terminal device and network system is also provided.
