Abstract

An example method is provided in one example embodiment and may include communicating a message for a group of one or more user equipment (UE) from a machine type communication-interworking function (MTC-IWF) to a packet data network gateway (PGW), wherein the message includes a group identity (ID) associated with the group of one or more UE; communicating the message from the PGW to one or more serving gateways (SGWs); and communicating the message from each of the one or more SGWs to each of the one or more UE of the group of the one via a tunnel for each of the one or more UE.

Claims

1. A method comprising:

establishing, for a packet data network gateway (PGW) and each of one or more serving gateways (SGWs), a group control plane tunnel and a group user plane tunnel between the PGW and each of the one or more SGWs for communicating group-based information between the PGW and each of the one or more SGWs for a group comprising a plurality of user equipment (UE);

communicating a message for the group from a machine type communication-interworking function (MTC-IWF) to the PGW using an interface that directly interconnects the MTC-IWF and the PGW, wherein the message comprises a group identifier (ID) associated with the group;

communicating the message from the PGW to one or more respective SGWs via a respective group user plane tunnel for each respective SGW;

determining whether each UE of the group is in at least one of a connected mode and an idle mode;

communicating the message from each of the one or more respective SGWs to each UE of the group via a respective user plane tunnel for each UE of the group determined to be in the connected mode;

paging each UE of the group determined to be in the idle mode; and

in response to determining that each of the UE determined to be in the idle mode have transitioned to the connected mode, communicating the message from each of the one or more respective SGWs to all of the UE of the group determined to have transitioned to the connected mode using the respective user plane tunnel for each UE of the group.

2. The method of claim 1, wherein a geographic restriction is included with the message to communicate the message to each UE of the group that is located within the geographic restriction.

3. The method of claim 1, wherein a Radio Access Technology (RAT) type restriction is included with the message to communicate the message to each UE of the group operating using the RAT type restriction.

4. The method of claim 1, wherein a geographic restriction and a

Radio Access Technology (RAT) type restriction are both included with the message.

5. The method of claim 1, wherein communicating the message by the one or more respective SGWs to each UE of the group includes communicating the message to each UE of the group using a destination address comprising at least one of:

a link-local Internet Protocol version 6 (IPv6) prefix for a particular UE; and

an IP version 4 (IPv4) address for a particular UE.

6. The method of claim 1, wherein communicating the message by each of the one or more respective SGWs to each UE of the group includes communicating the message to each UE of the group using a multicast destination address.

7. The method of claim 6, wherein the multicast destination address is shared by multiple groups, wherein each group comprises a plurality of UE.

8. The method of claim 1, further comprising at least one of:

receiving the message by the MTC-IWF from a service capability server using a Tsp interface;

receiving the message by the MTC-IWF from an application server using a Tsp interface; and

receiving the message by the MTC-IWF from a service capability exposure function using a Tsp interface.

9. The method of claim 1, further comprising:

requesting, by a particular SGW, a list that identifies one or more UE of the group determined to be in the connected mode within a particular geographic restriction associated with an Evolved Cell Global Identity (ECGI) or a Tracking Area Identity (TAI) for the particular SGW to apply the geographic restriction at the associated ECGI or TAI for communicating the message from the particular SGW to the UE of the group determined to be in the connected mode within the geographic restriction.

10. One or more non-transitory tangible media encoding logic that include instructions for execution that, when executed by a processor, is operable to perform operations comprising:

establishing, for a packet data network gateway (PGW) and each of one or more serving gateways (SGWs), a group control plane tunnel and a group user plane tunnel between the PGW and each of the one or more SGWs for communicating group-based information between the PGW and each of the one or more SGWs for a group comprising a plurality of user equipment (UE);

communicating a message for the group from a machine type communication-interworking function (MTC-IWF) to the PGW using an interface that directly interconnects the MTC-IWF and the PGW, wherein the message comprises a group identifier (ID) associated with the group;

communicating the message from the PGW to one or more respective SGWs via a respective group user plane tunnel for each respective SGW;

determining whether each UE of the group is in at least one of a connected mode and an idle mode;

communicating the message from each of the one or more respective SGWs to each UE of the group via a respective user plane tunnel for each UE of the group determined to be in the connected mode;

paging each UE of the group determined to be in the idle mode; and

in response to determining that each of the UE determined to be in the idle mode have transitioned to the connected mode, communicating the message from each of the one or more respective SGWs to all of the UE of the group determined to have transitioned to the connected mode using the respective user plane tunnel for each UE of the group.

11. The media of claim 10, wherein a geographic restriction is included with the message to communicate the message to each UE of the group that is located within the geographic restriction.

12. The media of claim 10, wherein a Radio Access Technology (RAT) type restriction is included with the message to communicate the message to each UE of the group operating using the RAT type restriction.

13. The media of claim 10, wherein a geographic restriction and a

Radio Access Technology (RAT) type restriction are both included with the message.

14. The media of claim 10, wherein communicating the message by the one or more respective SGWs to each UE of the group includes communicating the message to each UE of the group using a destination address comprising at least one of:

a link-local Internet Protocol version 6 (IPv6) prefix for a particular UE; and

an IP version 4 (IPv4) address for a particular UE.

15. The media of claim 10, wherein communicating the message by each of the one or more respective SGWs to UE of the group includes communicating the message to UE of the group using a multicast destination address.

16. The media of claim 10, the operations further comprising:

requesting, by a particular SGW, a list that identifies one or more of UE of the group determined to be in the connected mode within a particular geographic restriction associated with an Evolved Cell Global Identity (ECGI) or a Tracking Area Identity (TAI) for the particular SGW to apply the geographic restriction at the associated ECGI or TAI for communicating the message from the particular SGW to the one or more of the plurality of UE of the group determined to be in the connected mode within the geographic restriction.

17. An apparatus, comprising:

a memory element for storing data; and

a processor that executes instructions associated with the data, wherein the processor and memory element cooperate such that the apparatus is configured for;

establishing, for a packet data network gateway (PGW) and each of one or more serving gateways (SGWs), a group control plane tunnel and a group user plane tunnel between the PGW and each of the one or more SGWs for communicating group-based information between the PGW and each of the one or more SGWs for a group comprising a plurality of user equipment (UE);

communicating a message for the group from a machine type communication-interworking function (MTC-IWF) to the PGW using an interface that directly interconnects the MTC-IWF and the PGW, wherein the message comprises a group identifier (ID) associated with the group;
