Abstract

Apparatuses may stay synchronized with a network via a beacon signal that is transmitted at a set interval. Various communication-related activities may be planned around an instance when a beacon signal is expected, or a target beacon transmission time (TBTT). While some networked apparatuses are active during every TBTT, other apparatuses may operate using a diluted beacon period that is an integer multiple of the network beacon signal interval. Diluted beacon intervals may initiate periods of time during which apparatuses may become “aware” of other apparatuses. Awareness may comprise information related to communication configuration, apparatus status, and services offered by the various apparatuses in the network. Awareness information obtained during an awake window may also comprise information on data-related tasks that are pending in one or more apparatuses which may allow for the control of further data conveyance activities.

Claims

1. A method, comprising:

maintaining awareness information in an apparatus by interacting with other apparatuses in a wireless network during a control period portion of a periodic time interval between network beacon signals during which the apparatus is permitted to communicate awareness information within the wireless network, the control period portion following the network beacon signals,

wherein the awareness information comprises at least one of information regarding an availability of published data from the apparatus to other apparatuses in the wireless network and information regarding data searched for within the wireless network by the apparatus;

determining whether any data-related tasks relating to the apparatus are pending in the network by evaluating the awareness information in the apparatus,

wherein the data-related tasks comprise at least one of providing published data, that has been identified as available, from the apparatus to at least one of the other apparatuses in the wireless network and obtaining published data, that has been identified as available, from at least one of the other apparatuses in the wireless network that substantially matches the data searched for within the wireless network by the apparatus; and

if at least one data-related task relating to the apparatus is determined to be pending, entering a data sub-mode for interacting with at least one other apparatus within the network for some or all of a service data period portion of the periodic time interval between network beacon signals during which the apparatus is permitted to communicate service data information within the wireless network to perform the at least one data-related task, the service data period portion following completion of the control period portion.

2. The method of claim 1, wherein maintaining awareness information further comprises updating synchronization information in the apparatus.

3. The method of claim 1, wherein determining if any data-related tasks are pending comprises at least one of determining if data requested by the apparatus is available from another apparatus or if data has been requested from the apparatus by another apparatus.

4. The method of claim 1, further comprising entering a doze state in the apparatus if no data-related tasks are determined to be pending.

5. The method of claim 1, wherein the apparatus supports the data-related task by operating in the data sub-mode until the data-related task is complete or another network beacon signal is received in the apparatus.

6. The method of claim 5, wherein the apparatus remains in an active state in the network for any time left in a remaining portion of the periodic time interval between network beacon signals after the data-related task is complete.

7. The method of claim 1, further comprising causing the apparatus to establish a new connection utilizing a different wireless protocol to support data related tasks.

8. A computer program product comprising computer executable program code recorded on a non-transitory computer readable storage medium, the computer executable program code comprising:

code configured to cause an apparatus to maintain awareness information by interacting with other apparatuses in a wireless network during a control period portion of a periodic time interval between network beacon signals during which the apparatus is permitted to communicate awareness information within the wireless network, the control period portion following the network beacon signals,

wherein the awareness information comprises at least one of information regarding an availability of published data from the apparatus to other apparatuses in the wireless network and information regarding data searched for within the wireless network by the apparatus;

code configured to cause an apparatus to determine whether any data-related tasks relating to the apparatus are pending in the network by evaluating the awareness information in the apparatus,

wherein the data-related tasks comprise at least one of providing published data, that has been identified as available, from the apparatus to at least one of the other apparatuses in the wireless network and obtaining published data, that has been identified as available, from at least one of the other apparatuses in the wireless network that substantially matches the data searched for within the wireless network by the apparatus; and

code configured to cause an apparatus to, if at least one data-related task relating to the apparatus is determined to be pending, entering a data sub-mode for interacting with at least one other apparatus within the network for some or all of a service data period portion of the periodic time interval between network beacon signals during which the apparatus is permitted to communicate service data information within the wireless network to perform the at least one data-related task, the service data period portion following completion of the control period portion.

9. The computer program product of claim 8, wherein maintaining awareness information further comprises updating synchronization information in the apparatus.

10. The computer program product of claim 8, wherein determining if any data-related tasks are pending comprises at least one of determining if data requested by the apparatus is available from another apparatus or if data has been requested from the apparatus by another apparatus.

11. The computer program product of claim 8, further comprising entering a doze state in the apparatus if no data-related tasks are determined to be pending.

12. The computer program product of claim 8, wherein the apparatus supports the data-related task by operating in the data sub-mode until the data-related task is complete or another network beacon signal is received in the apparatus.

13. The computer program product of claim 12, wherein the apparatus remains in an active state in the network for any time left in a remaining portion of the periodic time interval between network beacon signals after the data-related task is complete.

14. The computer program product of claim 8, further comprising causing the apparatus to establish a new connection utilizing a different wireless protocol to support data related tasks.
