Abstract
Systems, methods, and machine-readable media for obtaining data from a cellular network core are described herein. A request from a network function residing outside of the cellular network core may be received by the cellular network core. The request may correspond to a request for data from the cellular network core. The request may be routed by a network exposure function (NEF) of the cellular network core to a user plane function (UPF) of the cellular network core. UPF data responsive to the request may be determined by the UPF. The UPF data may be transmitted from the UPF to the network function residing outside of the cellular network core.
Claims18
A method for obtaining data from a cellular network core, the method comprising:
- receiving, by the cellular network core, a request from a network function residing outside of the cellular network core, the request corresponding to a request for data from the cellular network core, wherein the request for data corresponds to a request for mapping information that maps an external IP address associated with user equipment residing outside of the cellular network core to an internal IP address maintained by the cellular network core;
- routing, by a network exposure function (NEF) of the cellular network core, the request to a user plane function (UPF) of the cellular network core;
- determining, by the UPF, UPF data responsive to the request for mapping information, wherein the UPF data comprises the mapping information;
- and
- transmitting the UPF data from the UPF to the network function residing outside of the cellular network core.
A system comprising:
- a cellular network core that comprises a user plane function (UPF) and a network exposure function (NEF), wherein the cellular network core is configured to perform operations comprising:
- receiving, by the cellular network core, a request from a network function residing outside of the cellular network core, the request corresponding to a request for data from the cellular network core, wherein the request for data corresponds to a request for mapping information that maps an external IP address associated with user equipment residing outside of the cellular network core to an internal IP address maintained by the cellular network core;
- routing, by the NEF of the cellular network core, the request to the UPF of the cellular network core;
- determining, by the UPF, UPF data responsive to the request for mapping information, wherein the UPF data comprises the mapping information;
- and
- transmitting the UPF data from the UPF to the network function residing outside of the cellular network core.
One or more non-transitory, machine-readable media having machine-readable instructions thereon which, when executed by one or more processing devices, cause the one or more processing devices to perform operations comprising:
- receiving a request from a network function residing outside of a cellular network core to the cellular network core, the request corresponding to a request for data from the cellular network core, wherein the request for data corresponds to a request for mapping information that maps an external IP address associated with user equipment residing outside of the cellular network core to an internal IP address maintained by the cellular network core;
- routing the request from a network exposure function (NEF) of the cellular network core to a user plane function (UPF) of the cellular network core;
- determining UPF data responsive to the request for mapping information, wherein the UPF data comprises the mapping information;
- and
- causing transmitting of the UPF data from the UPF to the network function residing outside of the cellular network core.
