NOTIFYING A USER EQUIPMENT UE, OVER A MOBILE NETWORK, OF AN UE APPLICATION TRIGGER REQUEST FROM A NETWORK APPLICATION SERVER
In an embodiment, there is provided a method for notifying a User Equipment UE (or a group of UE), over a mobile network, of an UE Application trigger request from a Network Application Server, said method comprising: sending UE Application trigger request information using a control plane path from the Network Application Server to the UE (or to an UE of the group) via a subscriber database (such as the HLR/HSS) and a node controlling UE access to the mobile network (such as a SGSN/MME).
1 . A method for notifying an User Equipment UE or a group of UE, over a mobile network, of an UE Application trigger request from a Network Application Server, said method comprising:
sending UE Application trigger request information using a control plane path from the Network Application Server to the UE or to an UE of the group via a subscriber database (HLR/HSS) and a node controlling UE access to the mobile network (SGSN/MME).
2 . A method according to claim 1 , comprising:
a Network Application Server that needs to trigger a connection request from a UE or a group of UE informs the subscriber database (HLR/HSS) about this need by providing UE application trigger request information.
3 . A method according to claim 1 , wherein UE application trigger request information contains one or more of:
the identity of the target UE;
the identity of the application;
a request counter associated to this request allowing to detect duplicated requests, to correlate requests with their acknowledgement and to allow the application to cancel a request;
optionally the IP@ (or FQDN) and/or TCP (or UDP) port of the Application Server that the UE has to contact;
optionally an urgency request indication.
optionally application specific information.
4 . A method according to claim 1 , comprising:
the subscriber database (HLR/HSS) transferring UE Application trigger request information to the node controlling UE access to the mobile network (SGSN/MME).
5 . A method according to claim 1 , comprising:
the subscriber database (HLR/HSS) storing UE Application trigger request information.
6 . A method according to claim 1 , comprising:
the subscriber database (HLR/HSS) erasing UE Application trigger request information upon getting an acknowledgement that it has been successfully delivered to the UE.
7 . A method according to claim 1 , comprising:
the node controlling UE access to the mobile network (SGSNIMME) transferring UE Application trigger request information to the UE via NAS signalling.
8 . A method according to claim 1 , comprising:
the node controlling UE access to the mobile network deciding to transfer UE Application trigger request information to the UE via NAS signalling immediately or to wait for next radio contact with the UE based on an urgency information in the UE Application trigger request.
9 . A method according to claim 1 , comprising:
UE receiving UE Application trigger request information via NAS signalling.
10 . A method according to claim 1 , comprising:
UE acknowledging reception of UE Application trigger request information, via NAS signalling.
11 . A method according to claim 1 , comprising:
UE triggering a corresponding Application upon reception, via NAS signalling, of UE Application trigger request information.
12 . A Network Application Server, configured to:
when needed to trigger a connection request from an UE or from a group of UE, informing a subscriber database about this need by providing UE application trigger request information.
13 . A mobile network subscriber database, configured to:
transfer UE Application trigger request information to a node controlling UE access to the mobile network.
14 . A mobile network subscriber database according to claim 13 , configured to:
store UE Application trigger request information.
15 . A mobile network subscriber database according to claim 13 , configured to:
erase UE Application trigger request information upon getting an acknowledgement that it has been successfully delivered to the UE.
16 . An node controlling UE access to a mobile network, configured to:
transfer UE Application trigger request information to the UE, via NAS signalling.
17 . An User Equipment UE, configured to:
receive UE Application trigger request information transferred to said UE via NAS signalling.
18 . An UE according to claim 17 , configured to:
acknowledge reception of UE Application trigger request information, via NAS signalling.
19 . An UE according to claim 17 , configured to:
trigger a corresponding Application upon reception of UE Application trigger request information.
