Extended Paging Period Negotiation for MTC UE Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile networks waste power in Machine Type Communication (MTC) User Equipment (UE) due to the use of a relatively short default paging period, even when the network side uses an extended paging period, which undermines the energy-saving benefits of extended Discontinuous Reception (DRX) periods.
Innovation Solution
The UE negotiates and selects an extended paging period with the MME/SGSN, allowing the E-UTRAN/UTRAN to use this extended period for paging, ensuring the UE monitors messages efficiently and reducing power consumption by avoiding the default short paging period.

Engineering Contradiction Analysis
1Use of energy by moving object
If the network side uses an extended paging period to reduce power consumption, then energy saving is improved, but the UE still uses a relatively short default paging period from system information, causing the extended DRX paging period to lose its meaning
Solution Approach 1:
The network side sends paging indication information to the UE to feedback the actual paging period being used. This allows the UE to adjust its monitoring behavior to match the extended paging period, ensuring consistency between network transmission and UE reception, and resolving the contradiction where the UE would otherwise use a short default period despite the network using an extended period for energy saving
Solution Approach 2:
Paging indication information acts as an intermediary mechanism between the network side and UE. It carries the actual paging period from the network to the UE, enabling the UE to synchronize its paging monitoring with the extended period used by the network, thereby maintaining energy saving benefits while ensuring proper information alignment

AI summary
Disclosed are a user equipment and a method and a system using an extended paging period to page, to overcome the defect that there is power waste because currently a UE still uses a relatively short default paging period in system information when an MME/SGSN uses an extended paging period. In the method, the MME/SGSN negotiates with a UE to obtain a first extended paging period; the MME/SGSN sends the first extended paging period and paging indication information which indicates to use the first extended paging period to page to a radio access network; the radio access network sends the first extended paging period in the system information and uses the first extended paging period to send a paging message; the UE selects a second extended paging period according to an extended paging period needed by the UE itself and the first extended paging period, and monitors the paging message according to the second extended paging period. The embodiment of the present application enables a UE in an idle mode to achieve an energy-saving effect by using the extended paging period.
