Communication Device Paging Delay Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing communication traffic due to smartphones and M2M/IoT services leads to a surge in requests for calling multiple terminals in a mobile network, causing a significant increase in C-plane processing load on the mobility management entity (MME) when multiple terminals respond with control signals simultaneously.
Innovation Solution
A communication device and method that delays the transmission of control signals from multiple terminals by determining and incorporating a delay time into a paging message, dispersing the timing of signal reception at the MME to manage the load effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If paging messages are transmitted to multiple terminals simultaneously, then the response time for terminal calling is improved, but the C-plane processing load on the MME increases significantly
Solution Approach 1:
The patent implements periodic action by introducing a delay mechanism where terminals transmit control signals at different time intervals rather than simultaneously. The MME determines a delay time for each terminal, causing control signals to be transmitted periodically over time. This resolves the contradiction by maintaining quick response capability while distributing the processing load across different time periods, preventing peak load congestion on the MME.
2Productivity
If multiple terminals transmit control signals simultaneously in response to paging messages, then the calling efficiency is improved, but the network processing capacity is exceeded
Solution Approach 1:
The patent applies preliminary action by having the MME determine and communicate delay times to terminals before the actual control signal transmission occurs. The paging message includes information about the delay time, allowing terminals to pre-coordinate their response timing. This preliminary timing arrangement maintains calling efficiency by ensuring all terminals respond while distributing the processing burden, preventing network capacity overload.

AI summary
The objective of the invention is to suppress increases in a C-Plane processing load on a mobile network side even if requests to call a plurality of terminals in the mobile network are generated within a short period of time. A communication device according to one mode of embodiment of the present invention is a communication device which transmits a paging message to a terminal that transmits a control signal for connecting to a network in response to receiving the paging message, wherein the communication device includes: a control unit which, in response to being requested to transmit paging messages to a plurality of terminals, determines, for each of the plurality of terminals, a time period for delaying transmission of the control signal; and a transmitting unit which transmits, to each of the plurality of terminals, the respective paging message including the time period by which the transmission of the control signal is to be delayed.
