Abstract
One embodiment of the present specification provides a method for managing subscriber information to respond to a network failure in a home subscriber server (HSS). The method can comprise the steps of: receiving a packet data network (PDN) failure indication; updating subscriber information related to a PDN on the basis of the PDN failure indication; and transmitting a message that indicates the update of the subscriber information.

A method for managing subscriber information to respond to a network failure, the method performed by a Home Subscriber Server (HSS) and comprising:
- receiving a Packet Data Network (PDN) failure indication;
- updating the subscriber information related to a PDN based on the PDN failure indication, by configuring the subscriber information such that a specific type of the PDN having the failure is not allowed;
- transmitting, to a Mobility Management Entity (MME), a first message, wherein the first message indicates that the subscriber information is updated,
- wherein a subsequent procedure is performed by the MME based on the updated subscriber information,
- wherein the subsequent procedure relates to establishing a connection to the PDN when there is no failure;
- receiving a failure restoration indication of the PDN;
- re-updating the subscriber information related to the PDN based on the failure restoration indication;
- and
- transmitting, to the MME, a second message, wherein the second message indicates that the subscriber information is re-updated.
A Home Subscriber Server (HSS) updating subscriber information to respond to a network failure, the HSS comprising:
- a receiver;
- a transmitter;
- and
- a controller, operatively coupled to the receiver and the transmitter, wherein the controller is configured to:
- control the receiver to receive a Packet Data Network (PDN) failure indication;
- update the subscriber information related to a PDN based on the PDN failure indication, by configuring the subscriber information such that a specific type of the PDN having the failure is not allowed;
- control the transmitter to transmit a first message, wherein the first message indicates that the subscriber information is updated,
- wherein a subsequent procedure is performed by a Mobility Management Entity (MME) based on the updated subscriber information,
- wherein the subsequent procedure relates to establishing a connection to the PDN when there is no failure;
- control the receiver to receive a failure restoration indication of the PDN;
- re-update the subscriber information related to the PDN based on the failure restoration indication;
- and
- control the transmitter to transmit a second message, wherein the second message indicates that the subscriber information is re-updated.
