Abstract
Systems and methods for controlling group triggers for Machine-Type Communications (MTC) services. In one embodiment, a Services Capability Server (SCS) of a network receives a request indicating a group trigger from an MTC server to activate an MTC feature in a group of MTC devices. In response to the group trigger request, the SCS queries a Policy and Charging Rules Function (PCRF) for network policies defined for group triggers, and controls delivery of the group trigger to the group of MTC devices based on the network policies provided by the PCRF.
Claims20
An apparatus comprising:
- a Services Capability Server (SCS) for a network, the SCS configured to receive a request from a Machine-Type Communications (MTC) server indicating a group trigger for activating an MTC feature in a group of MTC devices;
- the SCS further configured to query a Policy and Charging Rules Function (PCRF) for a network policy defined for the group trigger, and to control delivery of the group trigger to the group of MTC devices based on the network policy provided by the PCRF.
A method comprising:
- receiving a request in a Services Capability Server (SCS) of a network from a Machine-Type Communications (MTC) server, the request indicating a group trigger for activating an MTC feature in a group of MTC devices;
- querying a Policy and Charging Rules Function (PCRF) for a network policy defined for the group trigger;
- and
- controlling, in the SCS, delivery of the group trigger to the group of MTC devices based on the network policy provided by the PCRF.
An apparatus comprising:
- a Services Capability Server (SCS) configured to connect to a Policy and Charging Rules Function (PCRF) of a network, and configured to connect to a Machine-Type Communications (MTC) Interworking Function (IWF) of the network;
- wherein the PCRF is configured to store at least one network policy defined for a corresponding group trigger of a MTC service;
- wherein the SCS is further configured to receive a group trigger request from an MTC server, and to query the PCRF to identify the at least one network policy defined for the corresponding group trigger indicated by the group trigger request;
- and
- wherein the SCS is further configured to process the at least one network policy from the PCRF to identify one or more restrictions for the corresponding group trigger, and to transmit the group trigger request to the MTC IWF indicating at least one of the one or more restrictions.
