A computer network, comprising:

• a cellular network coupled to a user equipment (UE);
• and
• an application server for servicing an application running on the UE;
• wherein the application server is configured to:
• receive connection-status information associated with UE;
• and
• in response to determining that the UE is not reachable via the cellular network based on the received connection-status information, cease to send data packets associated with the application to the UE via the cellular network.

A computer network, comprising:

• a user equipment (UE) coupled to the cellular network and an application server, the application server being configured to service an application running on the UE;
• wherein the UE is configured to transmit connection-status information associated with UE to the application server to enable the application server to cease to send data packets associated with the application to the UE via the cellular network, in response to determining that the UE is not reachable via the cellular network based on the received connection-status information.
