A system configured for adjusting an IMS APN for a wireless device, the system comprising:
- one or more hardware processors configured by machine-readable instructions to:
- receive an inbound roaming communication from a wireless device to access a first IP multimedia core network subsystem (IMS) access point name (APN);
- transmit an update-location-request (ULR) for the wireless device to home subscriber server;
- receive an update-location-answer (ULA) for the wireless device;
- and
- in response to receiving ULA for the wireless device, adjust an IMS APN for the wireless device to the first IMS APN for wireless device.
A method for adjusting an IMS APN for a wireless device, the method comprising:
- receiving an inbound roaming communication from a wireless device to access a first IP multimedia core network subsystem (IMS) access point name (APN);
- transmitting an update-location-request (ULR) for the wireless device to home subscriber server;
- receiving an update-location-answer (ULA) for the wireless device;
- and
- in response to ULA for the wireless device, adjusting an IMS APN for the wireless device to the first IMS APN for wireless device.
A non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method for adjusting an IMS APN for a wireless device, the method comprising:
- receiving an inbound roaming communication from a wireless device to access a first IP multimedia core network subsystem (IMS) access point name (APN);
- transmitting an update-location-request (ULR) for the wireless device to home subscriber server;
- receiving an update-location-answer (ULA) for the wireless device;
- and
- in response to ULA for the wireless device, adjusting an IMS APN for the wireless device to the first IMS APN for wireless device.
