METHOD OF TRANSMITTING AND RECEIVING EMERGENCY PDN CONNECTION-RELATED SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR |
| 摘要 |
A method of transmitting and receiving an emergency PDN connection-related signal, which is transmitted and received by an MME in a wireless communication system, comprising the steps of: receiving a PDN connectivity request message from a UE; determining whether or not an IMS NNI exists between a HPLMN (home public land mobile network) of the UE and a PLMN of the MME and whether or not an anonymous emergency call is permitted; and if the IMS NNI does not exist and the anonymous emergency call is not permitted, transmitting a PDN connectivity reject message to the UE. |
