This patent describes a method for 5G devices to request and receive IP addresses from a network controller. It specifically handles how a device gets an address when connected to two different network groups simultaneously.
In the filing’s own words
The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.
What exactly they claim (claim 1)
1. A method performed by a mobile-termination (MT), the method comprising: transmitting, to a donor central unit (CU), a Radio Resource Control (RRC) message to request an allocation of an Internet Protocol (IP) address, the RRC message including information associated with IP version 4 or IP version 6; in response to the transmitting the RRC message, receiving, from the donor CU, an RRC reconfiguration message including first configuration information for a Master cell group (MCG), an IP address for the MCG, and second configuration information for a secondary cell group (SCG) in a multi-radio dual connectivity (MR-DC); identifying whether the second configuration information includes an IP address for the SCG in the MR-DC; and in case that the second configuration information includes the IP address for the SCG in the MR-DC, adding the IP address for the SCG in the MR-DC.
