UPF Programming Over Enhanced N9 Interface

A computing device comprising:

• a processor provided to execute computer readable instructions included on a non-transitory memory;
• and
• a non-transitory memory including computer readable instructions, that when executed by the processor, cause the computing device to:
• determine, by a first packet gateway controller connected to a first session manager device, that a user equipment moved to a geographical area that is served by a second session manager device;
• receive, by the first packet gateway device, a set of information for a second packet gateway device;
• transmit, by the first packet gateway device, a session establishment request via a first network interface to the second packet gateway controller using segment routing via a second network interface;
• receive, by the first packet gateway device, a session establishment response of the first network interface type from the second packet gateway device, via the second network interface, confirming the second packet gateway device's ability to meet a requested quality of service and maximum bit rate, and providing the second packet gateway device's address, and a set of tunnel identifiers;
• and
• transmit, by the first packet gateway device, the session establishment response of the first network interface type, to the first session manager device.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by a computing device with a non-transitory memory and one or more processors, cause the computing device to perform or cause performance of:

• determining, by a first packet gateway controller connected to a first session manager device, that a user equipment moved to a geographical area that is served by a second session manager device;
• receiving, by the first packet gateway device, a set of information for a second packet gateway device;
• transmitting, by the first packet gateway device, a session establishment request via a first network interface to the second packet gateway controller using segment routing via a second network interface;
• receiving, by the first packet gateway device, a session establishment response of the first network interface type from the second packet gateway device, via the second network interface, confirming the second packet gateway device's ability to meet a requested quality of service and maximum bit rate, and providing the second packet gateway device's address, and a set of tunnel identifiers;
• and
• transmitting, by the first packet gateway device, the session establishment response of the first network interface type, to the first session manager device.
