METHOD AND DEVICE FOR PROCESSING FAILURES OF MOBILITY MANAGEMENT DEVICE IN IDLE MODE SIGNALING REDUCTION ACTIVATED SCENE

摘要

Disclosed in the embodiments of the present invention are a method and device for processing failures of a mobility management device in an Idle mode Signaling Reduction (ISR) activated scene. The method includes that: a Serving Gateway (S-GW) detects failures of a first mobility management device; when said S-GW receives downlink user plane or control plane data of a user equipment (UE), said S-GW pages said UE, by a downlink data notification message which includes the identification information of said UE, in the first Radio Access Network (RAN) where said first mobility management device is located.
