determines whether the requested new network connection cannot be established; determines, from the packet routing information, whether direct offload is permitted; and sends the data packet using a second network connection type in response to determining that direct offload is permitted.
5. The apparatus of claim 1, wherein the processor further determines from the packet routing access information whether direct offload to a connected access network is preferred for the data packet, wherein the processor determines whether the packet routing information matches a network connection in response to determining that direct offload to the connected access network is not preferred.
6. The apparatus of claim 1, wherein the processor further:
receives a user equipment routing policy (�URP�) from the mobile communication network, the URP comprising a plurality of prioritized URP rules, each prioritized URP rule comprising a traffic filter component and at least of one of: a slice information component, a continuity type component, and a data network component; wherein determining packet routing information for the data packet comprises the processor:
comparing characteristics of the data packet to traffic filter components of the URP;
identifying a matching rule, the matching rule being a highest priority URP rule whose traffic filter component matches the characteristics of the data packet; and
