Forwarding Plane Gateway Paging Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The separation of control plane and forwarding plane gateways in evolved network systems leads to frequent signaling interworking, resulting in increased paging times due to circuitous message forwarding, especially when the control plane gateway is centralized and the forwarding plane gateways are distributed.
Innovation Solution
A paging method where the forwarding plane gateway receives a downlink packet and sends a second paging message directly to base stations, determining the destination address based on the downlink packet, thereby reducing the need for signaling interworking with the control plane gateway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the control plane gateway is separated from the forwarding plane gateway and deployed in a centralized manner, then network architecture flexibility and scalability are improved, but signaling interworking frequency increases and paging time is extended
Solution Approach 1:
The patent segments the gateway functions into control plane gateway and forwarding plane gateway, with the control plane gateway handling signaling and the forwarding plane gateway handling data forwarding and paging operations. This segmentation allows the forwarding plane gateway to independently send paging messages to base stations without requiring control plane gateway intervention, thereby reducing signaling interworking frequency and paging time while maintaining the architectural flexibility benefits of separation.
Solution Approach 2:
The forwarding plane gateway acts as an intermediary that receives downlink packets and autonomously generates and sends paging messages to base stations. This intermediary role eliminates the need for the control plane gateway to directly page terminals, reducing the signaling path length and interworking frequency between the two gateways while maintaining the centralized control plane architecture.
2Reliability
If the control plane gateway and forwarding plane gateway frequently interwork for paging operations, then control and forwarding coordination is maintained, but message forwarding becomes circuitous and paging delay increases
Solution Approach 1:
The patent extracts the paging message sending function from the control plane gateway and assigns it to the forwarding plane gateway. The forwarding plane gateway independently determines destination base stations and sends paging messages directly, eliminating the circuitous signaling path that would otherwise require control plane gateway involvement. This extraction maintains coordination reliability through pre-configured base station information while dramatically improving message forwarding efficiency.

AI summary
Embodiments of the present invention disclose a paging method, a related device, and a system. The paging method includes: receiving, by a forwarding plane gateway, a downlink packet; and sending, by the forwarding plane gateway, a second paging message to at least one base station according to the downlink packet, where the second paging message is used for paging a terminal. In the paging method in the present invention, the forwarding plane gateway sends the second paging message to page the terminal, and a control plane gateway is not required to page the terminal.
