Method and apparatus for monitoring user equipment reachability in wireless communication system
First Claim
1. A method for monitoring User Equipment (UE) reachability in a wireless communication system, comprising:
- receiving, by a Mobility Management Entity (MME), a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server (HSS);
detecting, by the MME, the UE reachability when the UE will become reachable for paging in case that extended Discontinuous Reception (DRX) is applied to the UE; and
sending, by the MME, a UE reachability notification to a Service Capability Exposure Function (SCEF) before a next paging occasion of the UE,wherein the maximum response time indicates a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, andwherein an occasion when the UE reachability notification is transmitted is determined by taking into consideration the maximum response time.

Abstract
Disclosed herein are a method and apparatus for monitoring UE reachability in a wireless communication system. A method for monitoring UE reachability may include receiving, by a Mobility Management Entity, a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server, detecting, by the MME, the UE reachability if it is expected that paging is able to be transmitted to UE when extended Discontinuous Reception is applied to the UE, and sending, by the MME, a UE reachability notification to a Service Capability Exposure Function before a next paging occasion of the UE, wherein the maximum response time may indicate a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted may be determined by taking into consideration the maximum response time.

8. A Mobility Management Entity (MME) for monitoring User Equipment (UE) reachability in a wireless communication system monitoring, the MME comprising:
-
a communication module configured to send and receive signals; and a processor configured to control the communication module, wherein the processor is configured to; receive a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server (HSS), detect the UE reachability when the UE will become reachable for paging in case that extended Discontinuous Reception (DRX) is applied to the UE, and send a UE reachability notification to a Service Capability Exposure Function (SCEF) before a next paging occasion of the UE, wherein the maximum response time indicates a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted is determined by taking into consideration the maximum response time. - View Dependent Claims (9)
