Wireless Page Transmission Policy-Based RAT Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in page transmission and response processes, particularly when mobile devices need to access multiple radio access technologies (RATs) for different services, leading to suboptimal network resource utilization and increased complexity in managing paging procedures.
Innovation Solution
The system allows mobile devices to receive page transmissions with service-specific information, enabling them to determine and access the most suitable wireless communications networks based on service requirements, using a policy that prioritizes RATs for efficient communication, and permits paging responses to be transmitted over different networks or RATs as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile devices access the network that initiated the page transmission, then network coordination is simplified, but network resource utilization becomes suboptimal and communication efficiency decreases
Solution Approach 1:
Instead of requiring mobile devices to access the network that initiated the page transmission, the patent inverts this approach by allowing devices to access any available network. The network that initiated the page receives a tunnelled indication of the service request and forwards it appropriately, reversing the traditional direct access model to improve resource utilization while maintaining coordination through tunnelling mechanisms.
Solution Approach 2:
The patent introduces an intermediary tunnelling mechanism where the network that initiated the page transmission acts as a mediator. When a mobile device accesses a different network, the service request is tunnelled through the initiating network to maintain proper coordination and routing, allowing flexible network access while preserving network management structure.
2Loss of energy
If mobile devices must access the same network for paging responses, then network management is simplified, but network resource utilization decreases and communication performance suffers
Solution Approach 1:
The patent applies universality by enabling mobile devices to access any available network for paging responses, not just the network that initiated the page. This multi-network access capability allows devices to utilize the most appropriate network based on current conditions, improving resource utilization while the tunnelling mechanism ensures proper routing and management across different networks.
Solution Approach 2:
The patent changes the parameter of network selection from a fixed requirement (must use initiating network) to a flexible parameter that can be adjusted based on network availability and service requirements. The tunnelling mechanism adapts to different network configurations, allowing optimal resource utilization while maintaining manageable paging procedures through standardized indication and forwarding processes.
3Productivity
If mobile devices access different networks based on service requirements, then network resource utilization improves, but paging procedure complexity increases
Solution Approach 1:
The tunnelling mechanism serves as an intermediary that simplifies the complexity introduced by multi-network access. The network that initiated the page acts as a mediator, receiving service requests from devices accessing different networks and forwarding them appropriately. This intermediary approach allows flexible network selection while maintaining standardized paging procedures and reducing overall system complexity.
Solution Approach 2:
The patent implements feedback mechanisms where networks exchange indications about service requests and device locations. This feedback loop allows the system to adapt to different network configurations and service requirements, managing the complexity of multi-network access through coordinated information exchange and standardized response handling.

AI summary
Mobile devices may receive page transmissions that include information related to a service for which the mobile device is being paged. The mobile device may be provided with a policy that describes a priority of radio access technologies (RATs) based on the type of service for which the mobile device is being paged. The mobile device, based at least in part on the service information, may access one or more of the wireless communications networks based on the identified service and/or based on the policy. A page transmission may include an indication of a RAT that is to be used for the page response and/or an index into the policy. A base station that transmits a page transmission may include an identifier of a particular network that is to be accessed in response to the page.
