Abstract
There is provided a system, method, and interfaces for control plane device triggering for a Public Land Mobile Network Packet Data Network (PDN). The network is configured to employ triggering via a T6a interface for an originating Machine-type communication server request to a Service Capability Exposure Function Server to initiate a PDN connection for User Equipment.
Claims37
A method for control plane device triggering, comprising:
- receiving a device action trigger request message from an originating Machine-type communication server (MTC Server) for user equipment (UE) into a Service Capability Exposure Function (SCEF) Server;
- sending a connection management request from the SCEF Server to a Mobility Management Entity (MME) Server via an interface connecting the SCEF Server and the MME Server, the connection management request not including an Evolved Packet System (EPS) bearer ID allocation;
- establishing a personal communications network connectivity procedure between the UE and the MME Server;
- and
- generating and sending a connection management answer from the MME Server to the SCEF Server.
A Service Capability Exposure Function (SCEF) Server computer comprising a program memory comprising instructions configured to, when executed by a processor, implement a T6 Interface configured to support a Service Capability Server (SCS) initiated SCEF Packet Data Network (PDN) connection comprising a Content Management Request Message comprising an Evolved Packet System (EPS) Bearer Identity element.
A Services Capability Server (SCS) comprising a program memory comprising instructions configured to, when executed by a processor, implement a Tsp Interface to an Machine Type Communication Inter Working Function (MTC-IWF) component and configured to support SCS Initiated Device Trigger Delivery to establish a Service Capability Exposure Function (SCEF) Packet Data Network (PDN) Connection in an Indirect Model of Machine Type Communication (MTC) Architecture comprising:
- a Device Trigger Via SCEF element.
A Services Capability Server (SCS) comprising a program memory comprising instructions configured to, when executed by a processor, implement an S6 Interface to a Home Subscriber Service (HSS) configured to support a Services Capability Server SCS Initiated Device Trigger Delivery to establish a Service Capability Exposure Function (SCEF) Packet Data Network (PDN) Connection in Indirect Model of Machine Type Communication Architecture comprising:
- a Requested Service element;
- and
- a Service Selection element comprising an APN Network Identifier,
- wherein a Service ID value for the Requested Service element includes a Device Triggering on a T6 device trigger value.
A system comprising:
- a Service Capability Exposure Function (SCEF) Server including an interface connecting the SCEF Server to a Mobility Management Entity (MME) Server;
- the SCEF Server comprising a computer processor and program memory comprising instructions configured to, when executed by the processor:
- receive a device action trigger request message from an originating Machine-type communication server (MTC Server) for user equipment (UE);
- send a connection management request from the SCEF Server to the MME Server via the interface connecting the SCEF Server and the MME Server, the connection management request not including an Evolved Packet System (EPS) bearer ID allocation;
- and
- receive a connection management answer from the MME Server via the interface;
- wherein the SCEF Server is configured to establish a personal communications network connectivity procedure between the UE and the MME Server.
