Abstract

Systems, methods, and instrumentalities to optimize procedures relating to machine type communication devices. Individual UEs may be grouped together in order to optimize procedures relating to members of the group. For example, a group of UE devices may be predefined or a group may be configured by a network associated with the UEs. One or more of the members of the group may be designated as a special UE or a master UE. The special UE or master UE may perform an action on behalf of one or more members of the group.

Claims

1-6. -6. (canceled)

7. A method for optimizing communications relating to machine type communication. devices, the method comprising:

receiving, at a non-special UE, an indication to operate according to an optimization procedure, wherein the optimization procedure is configured for the non-special UE, and wherein the non-special UE is a member of a group of machine type communication devices that includes a special UE configured to perform an action on behalf of the group of machine type communication devices; and

performing, by the non-special UE, the optimization procedure, comprising;

performing a cell reselection measurement;

performing cell reselection; and

monitoring a source cell for a confirmation message, wherein the monitoring is performed without sending an uplink transmission to a network before a time period has expired.

9. The method of claim 7, wherein the non-special UE foregoes sending a cell update to the network when the confirmation message is received before the time period has expired.

10. The method of claim 7, wherein the non-special UE sends a cell update to the network when the confirmation message is not received before the time period has expired.

8. (canceled)

11-16. -16. (canceled)

17. A non-special UE configured, at least in part, to:

receive an indication to operate according to an optimization procedure, wherein the optimization procedure is configured for a non-special UE, and wherein the non-special UP is a member of a group of machine type communication devices that includes a special UE configured to perform an action on behalf of the group of machine type communication devices; and

perform the optimization procedure, wherein the non-special UE is configured to;

perform a cell reselection measurement;

perform cell reselection; and

monitor a source cell for a confirmation message wherein the monitoring is performed without sending an uplink transmission to a network before a time period has expired.

19. The non-special UE of claim 17, wherein the UE foregoes sending a cell update to the network when the confirmation message is received before the time period has expired.

20. The non-special UE of claim 17, wherein the non-special UE sends a cell update to the network when the confirmation message is not received before the time period has expired.
