Facilitating radio access technology (RAT) interworking for user equipment in a mobile network environment

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor, cause the processor to perform operations, comprising:

• obtaining, from a user equipment (UE) that is connected to a first wireless wide area (WWA) radio access technology (RAT) type of a mobile core network, a Non-Access Stratum (NAS) RAT change request for the UE to connect to a second WWA RAT type, wherein the NAS RAT change request includes a location indicator identifying a location of the UE, a parameter identifying the second WWA RAT type, and a cause indicator indicating a poor quality of the first WWA RAT type as a cause for the request for the UE to connect to the second WWA RAT type;
• querying a subscription management element of the mobile core network to determine whether the UE is subscribed to connect to the second WWA RAT type at the location of the UE;
• and
• based, at least in part upon determining that the UE is subscribed to connect to the second WWA RAT type at the location, sending a policy to the UE that includes an indicator of the second WWA RAT type to cause the UE to connect to the second WWA RAT type.

A mobility management node of a mobile core network comprising:

• at least one memory element for storing data;
• and
• at least one processor for executing instructions associated with the data, wherein executing the instructions causes the mobility management node to perform operations, comprising:
• obtaining, from a user equipment (UE) that is connected to a first wireless wide area (WWA) radio access technology (RAT) type, a Non-Access Stratum (NAS) RAT change request for the UE to connect to a second WWA RAT type, wherein the NAS RAT change request includes a location indicator identifying a location of the UE, a parameter identifying the second WWA RAT type, and a cause indicator indicating a poor quality of the first WWA RAT type as a cause for the request for the UE to connect to the second WWA RAT type;
• querying a subscription management element of the mobile core network to determine whether the UE is subscribed to connect to the second WWA RAT type at the location of the UE;
• and
• based, at least in part upon determining that the UE is subscribed to connect to the second WWA RAT type at the location, sending a policy to the UE that includes an indicator of the second WWA RAT type to cause the UE to connect to the second WWA RAT type.
