Paging Resource Scheduling for LC-MTC and Conventional UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE systems, the limited bandwidth for paging messages in conventional art affects both low-cost machine type communication (LC-MTC) devices and conventional user equipment (UE), leading to capacity constraints.
Innovation Solution
A method and apparatus for paging user equipment that determine scheduling resources based on UE type, using discontinuous reception (DRX) periods and mapping relationships to send paging messages on different subframes, thereby reducing interference between LC-MTC devices and conventional UEs.

Engineering Contradiction Analysis
1Ease of operation
If paging messages are scheduled within the limited bandwidth of 1.4M for LC-MTC devices, then LC-MTC devices can receive paging messages normally, but the capacity of paging messages is limited and conventional UEs are affected
Solution Approach 1:
The patent divides the paging message transmission into two separate bandwidth regions: a first bandwidth region (1.4M) for LC-MTC devices and a second bandwidth region for conventional UEs. This segmentation allows each device type to access paging messages in their respective bandwidth regions, resolving the contradiction by enabling LC-MTC devices to receive paging messages in the limited 1.4M bandwidth while conventional UEs can access the full available bandwidth, thereby increasing overall paging message capacity without affecting either device type.
2Ease of operation
If paging messages are scheduled within the limited bandwidth of 1.4M for LC-MTC devices, then LC-MTC devices can receive paging messages normally, but conventional UEs are affected
Solution Approach 1:
The patent segments the bandwidth into a first bandwidth region (1.4M) dedicated to LC-MTC devices and a second bandwidth region for conventional UES. By scheduling paging messages for LC-MTC devices only within the first bandwidth region and allowing conventional UEs to access the second bandwidth region, the patent eliminates interference and ensures that LC-MTC device operations do not negatively impact conventional UE performance.
Solution Approach 2:
The patent applies different quality characteristics to different bandwidth regions: the first bandwidth region is optimized for LC-MTC devices with specific scheduling parameters, while the second bandwidth region maintains full capabilities for conventional UEs. This local quality differentiation ensures that each device type operates in an optimized environment without harmful interference to the other.

AI summary
Embodiments of the present disclosure provide a method and an apparatus for paging a user equipment. A paging message sent by an MME is received, where the foregoing paging message includes indication information of a UE type; a scheduling resource for sending a paging message of the foregoing UE type is determined according to the indication information of the UE type; and the paging message of the foregoing UE is sent on the scheduling resource, thereby reducing impact on a conventional type of UE that is caused by a limitation on a bandwidth of a received signal of a special type of UE.
