Abstract
A mobility management entity (MME) may receive a request that identifies an access point name (APN) for a packet data connection for a wireless communication device (WCD). The APN may be authorized by the WCD according to a service profile in a home subscriber server (HSS), and the APN may be associated with a subscribed packet data policy. However, if the MME determines that it cannot validate the request (e.g., because the HSS is unreachable or non-responsive), the MME may send to a packet gateway a session request that identifies the WCD and includes a dummy APN. The dummy APN is associated with a substitute packet data policy that differs from the subscribed packet data policy. Based on the session request including the dummy APN, the packet gateway may establish a packet data session for the WCD in accordance with the substitute packet data policy.
