System and a method for establishing communications in a 5G open radio network (O-RAN)

An element management system (EMS) configured to operate in a 5G Open Radio Access Network (O-RAN), the system comprising:

• at least one processor;
• and
• memory coupled to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving, from a device, a connection request for the device to establish communication with the a 5G O-RAN network, the connection request including capability information pertaining to the device;
• transmitting, to a dynamic host configuration protocol (DHCP) server associated with the device, a request for an Internet Protocol (IP) address associated with the device;
• receiving, from the DHCP server in response to the request, an IP address of a cell site router (CSR) deployed between the device and the DHCP server such that communications between the device and the DHCP server are routed through the CSR;
• assigning, based at least in part on the capability information pertaining to the device, (i) one or more identifiers and (ii) a virtual distribution unit (vDU) associated with the 5G O-RAN to the device;
• updating a database to link the device with the one or more identifiers and the IP address of the CSR, the database storing information representing connections among network entities of the 5G O-RAN;
• transmitting, to the device, an IP address of the vDU for the device to establish connection with the 5G O-RAN.

A non-transitory machine-readable storage device storing a program, which upon execution causes one or more computers of an element management system (EMS) in a 5G Open Radio Access Network (O-RAN) to perform operations comprising:

• receiving, from a device, a connection request for the device to establish communication with a 5G O-RAN network, the connection request including capability information pertaining to the device;
• transmitting, to a dynamic host configuration protocol (DHCP) server associated with the device, a request for an Internet Protocol (IP) address associated with the device;
• receiving, from the DHCP server in response to the request, an IP address of a cell site router (CSR) deployed between the device and the DHCP server such that communications between the device and the DHCP server are routed through the CSR;
• assigning, based at least in part on the capability information pertaining to the device, (i) one or more identifiers and (ii) a virtual distribution unit (vDU) associated with the 5G O-RAN to the device;
• updating a database to link the device with the one or more identifiers and the IP address of the CSR, the database storing information representing connections among network entities of the 5G O-RAN;
• and
• transmitting, to the device, an IP address of the vDU for the device to establish connection with the 5G O-RAN.
