Paging Initiation in Cellular Mobile Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paging methods in cellular mobile communication systems are inefficient, requiring extensive signaling and multiple steps to re-establish data transmission to idle terminals, which can change their location without notification, leading to delays and increased network load.
Innovation Solution
The method involves direct data transmission to the last known radio transmission device for the terminal in the idle state, with the option to initiate paging directly from this device to the mobility control device if the terminal is no longer reachable, minimizing signaling and optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional paging method is used with data transmission device initiating paging request to mobility control device, then terminal location can be determined, but signaling traffic increases and connection establishment is delayed
Solution Approach 1:
The radio transmission device performs preliminary action by directly initiating paging requests to radio transmission devices in neighboring cells without waiting for mobility control device intervention. This preliminary direct paging action reduces the time required for connection establishment while maintaining reliable terminal location determination through the hierarchical paging structure.
Solution Approach 2:
The invention extracts the paging initiation function from the mobility control device and assigns it directly to the radio transmission device. This extraction eliminates unnecessary signaling steps through the mobility control device, reducing signaling traffic and accelerating connection establishment while preserving the ability to determine terminal location.
2Measurement precision
If traditional paging method is used with multiple signaling steps, then terminal location can be determined accurately, but network load increases
Solution Approach 1:
The invention extracts the paging initiation function from the mobility control device and assigns it directly to the radio transmission device. This extraction eliminates unnecessary signaling steps through the mobility control device, reducing signaling traffic while preserving the ability to determine terminal location through direct radio paging messages.
Solution Approach 2:
The paging process is segmented into direct radio paging messages between radio transmission devices and the terminal, bypassing the mobility control device for the actual paging transmission. This segmentation reduces the quantity of signaling traffic while maintaining location determination accuracy through the distributed paging structure.
3Reliability
If data transmission device initiates paging through mobility control device, then terminal can be reached, but device complexity increases
Solution Approach 1:
The invention extracts the paging initiation function from the complex multi-device signaling path and assigns it directly to the radio transmission device. This simplifies the device complexity by eliminating the need for coordinated signaling between data transmission device and mobility control device, while maintaining terminal reachability through direct radio paging.
Solution Approach 2:
The radio transmission device performs self-service by autonomously initiating paging requests to neighboring cells without requiring intervention from the mobility control device. This self-service approach reduces device complexity by eliminating complex inter-device signaling protocols while ensuring terminal reachability through direct paging.

AI summary
The invention relates to a method for carrying out paging in a cellular mobile communication system. A terminal is operated in a first radio cell of the mobile communication system which is in an idle state, data is provided in a data transmission device of the mobile communication system for transmission to the terminal. According to the invention, the information is first transmitted to a radio transmission device supplying the first radio cell with radio signals, whereupon a paging is carried out or initiated by the radio transmission device in order to activate the terminal and to be able to transmit the data.
