Support of mobile-terminated application services in a mobile system
A method for support of mobile-terminated application services in a mobile system is provided. The method is based on a User Equipment UE subscription The method includes enabling triggering of at least one network Application associated with a given of one or more subscribed Access Point Name APN, upon said UE being reachable again after failure of a mobile network procedure to reach said UE via a Packet Data Network PDN connection established for said UE and said APN. A Home Subscriber Server HSS associated with the method is also provided. A Mobility Management Server MME, or a Serving GPRS Support Node SGSN associated with the method is also provided.
1. An apparatus, comprising:

at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
determine if a downlink data notification failure associated with a downlink data delivery failure occurs for a user equipment,
determine if information associated with a subscription for notifying a network application when the user equipment is available after a downlink data notification failure has been received,
if said downlink data notification failure occurs and said information has been received, determine if the user equipment becomes reachable after said downlink data notification failure, and
if the user equipment becomes reachable after said downlink data notification failure, send a notification indicating that the user equipment is available after said downlink data notification failure.
2. The apparatus according to claim 1 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform:
receive said information from a mobile network subscriber database.
3. The apparatus according to 1 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform:
if said information has been received, set a flag, referred to as a downlink data notification failure flag, in case of downlink data notification failure.
4. The apparatus according to claim 1 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform:
if a downlink data notification failure flag has been set after a downlink data notification failure, and if the user equipment becomes reachable, send a notification indicating that the user equipment is available after said downlink data notification failure, and clear the downlink data notification failure flag.
5. The apparatus according to claim 1 , wherein:
said user equipment is a user equipment using a power saving mode.
6. The apparatus according to claim 1 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to perform:
receive said information as part of subscription data of the user equipment.
7. The apparatus according to claim 1 , wherein:
said apparatus comprises a mobility management entity.
8. A method comprising:
determining if a downlink data notification failure associated with a downlink data delivery failure occurs for a user equipment,
determining if information associated with a subscription for notifying a network application when the user equipment is available after a downlink data notification failure has been received,
if said downlink data notification failure occurs and said information has been received, determining if the user equipment becomes reachable after said downlink data notification failure, and
if the user equipment becomes reachable after said downlink data notification failure, sending a notification indicating that the user equipment is available after said downlink data notification failure.
9. The method according to claim 8 , comprising:
if said information has been received, setting a flag, referred to as downlink data notification failure flag, in case of downlink data notification failure.
10. The method according to claim 8 , comprising:
if a downlink data notification failure flag has been set after a downlink data notification failure, and if the user equipment becomes reachable, sending a notification indicating that the user equipment is available after said downlink data notification failure, and clearing the downlink data notification failure flag.
11. The method according to claim 8 , comprising:
receiving said information from a mobile network subscriber database.
12. The method according to claim 8 , comprising:
receiving said information as part of subscription data of the user equipment.
13. The method according to claim 8 , wherein:
said user equipment is a user equipment using a power saving mode.
