Method and network device for responding to request
A first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.
1. A method performed by an access and mobility management function (AMF), the method comprising:
receiving, from a session management function (SMF), a request associated with data notification for a wireless device, wherein the wireless device is not in a Mobile Initiated Connection Only (MICO) mode;
detecting that the wireless device is in a non-allowed area in which a communication service is restricted;
rejecting the request and notifying the SMF that the wireless device is in the non-allowed area, unless the data notification is for a regulatory prioritized service;
storing information informing that the SMF has been notified that the wireless device is in the non-allowed area; and
transmitting paging for the wireless device to a radio access network device based on that the data notification is for the regulatory prioritized service.
2. The method according to claim 1 , wherein the radio access network device is a base station (BS).
3. The method according to claim 1 , wherein the regulatory prioritized service is an emergency service or a multimedia priority service (MPS).
4. An access and mobility management function (AMF) configured to operate in a wireless communication system, the AMF comprising:
a memory;
a transceiver; and
a processor operatively coupled to the transceiver and the memory, wherein the processor is configured to:
control the transceiver to receive, from a session management function (SMF), a request associated with data notification for a wireless device, wherein the wireless device is not in a Mobile Initiated Connection Only (MICO) mode;
detect that the wireless device is in a non-allowed area in which a communication service is restricted;
reject the request and control the transceiver to notify the SMF that the wireless device is in the non-allowed area, unless the data notification is for a regulatory prioritized service;
store, in the memory, information informing that the SMF has been notified that the wireless device is in the non-allowed area; and
control the transceiver to transmit paging for the wireless device to a radio access network device based on that the data notification is for the regulatory prioritized service.
5. The AMF according to claim 4 , wherein the radio access network device is a base station (BS).
6. The AMF according to claim 4 , wherein the regulatory prioritized service is an emergency service or a multimedia priority service (MPS).
