US 8,818,426 B2 · Scalable transmission or device trigger requests

Abstract

Systems and methods for scalable triggering of machine type communication (MTC) devices are disclosed. One method comprises receiving for a selected period of time, at an MTC inter working function (IWF) module, a plurality of device trigger messages that are sent from a plurality of MTC servers. The plurality of device trigger messages are aggregated at the MTC IWF. A mobility management entity (MME) or Serving General Packet Radio Service (GPRS) Support Node (SGSN) for each device trigger message is identified. The aggregated device trigger messages are then sent to the identified MME or SGSN associated with each device trigger message to enable the identified MME SGSN to send the device trigger messages to a radio access network for transmission to the MTC devices.

Claims17

Dependent claims

A scalable triggering mechanism for machine type communication (MTC) devices, comprising:

a trigger aggregation module (TAM) configured to operate on a radio system fixed network interface, wherein the TAM is configured to:
receive an aggregate device trigger message containing a plurality of MTC device trigger messages and a user equipment (UE) identity for each MTC device trigger message;
and
communicate a paging message to at least one radio access network (RAN) with a list of the UE identities contained in the aggregate device trigger message to enable the RAN to communicate a paging message with a list of paging records to each identified UE.

1 more element

A non-transitory machine readable storage medium comprising a plurality of instructions adapted to be executed to implement the method for scalable triggering of machine type communication (MTC) devices, comprising:

receiving an aggregate trigger message at a radio system-fixed network interface, wherein the aggregate trigger message contains a plurality of MTC device trigger messages and a user equipment (UE) identity for each MTC device trigger message;
and
communicating a paging message from the radio system-fixed network interface to at least one radio access network (RAN) with a list of the UE identities contained in the aggregate device trigger message to enable the RAN to communicate a paging message with a list of paging records to each identified UE.

Dependencies are inferred from the claim text.
