Establishing connectivity to legacy generation wireless network via a fully service based network

An apparatus for wireless communications at a distributed unit, comprising:

• a processor;
• memory coupled with the processor, the memory storing instructions executable by the processor to cause the apparatus to:
• communicate a service request received from a user equipment (UE) via a first radio access technology to a core network service, the core network service offered by a service-based network of the first radio access technology and configured to interface with a radio access network associated with the distributed unit, wherein the distributed unit is associated with the first radio access technology, and wherein the core network service is associated with a central unit of a second radio access technology;
• communicate a service context received from the core network service to the UE via the first radio access technology, the service context for communications between the UE and the core network service in accordance with the first radio access technology and indicating a destination associated with the core network service;
• and
• communicate a service message received from the UE via the first radio access technology to the core network service in accordance with the service context, the service message comprising the destination and a payload in a format associated with the second radio access technology.

An apparatus for wireless communications at a core network service, comprising:

• a processor;
• memory coupled with the processor, the memory storing instructions executable by the processor to cause the apparatus to:
• receive, from a user equipment (UE) via a distributed unit associated with a first radio access technology, a service request indicating the core network service, the core network service offered by a service-based network of the first radio access technology and configured to interface with a radio access network associated with the distributed unit, wherein the core network service is associated with a central unit of a second radio access technology;
• transmit, to the UE via the distributed unit in accordance with the first radio access technology, a service context for communications between the UE and the core network service based at least in part on the service request, the service context indicating a destination associated with the core network service;
• and
• receive, from the UE via the distributed unit, a service message in accordance with the service context, the service message comprising the destination and a payload in a format associated with the second radio access technology.

A method for wireless communications at a user equipment (UE), comprising:

• receiving, from a distributed unit via a first radio access technology, control information indicating a core network service offered by a service-based network of the first radio access technology and configured to interface with a radio access network associated with the distributed unit, wherein the distributed unit is associated with the first radio access technology, and wherein the core network service is associated with a central unit of a second radio access technology;
• transmitting, to the distributed unit via the first radio access technology and based at least in part on the control information, a service request indicating the core network service associated with the central unit of the second radio access technology;
• receiving, from the distributed unit via the first radio access technology, a service context for communicating with the core network service in accordance with the first radio access technology based at least in part on the service request, the service context indicating a destination associated with the core network service;
• and
• transmitting, to the distributed unit via the first radio access technology, a service message in accordance with the service context, the service message comprising the destination and a payload in a format associated with the second radio access technology.
