Abstract

An approach is provided for establishing one or more communication sessions in a cloud computing environment and maintaining the establishment of the one or more communication sessions while managing system resource and power resource consumption. The approach involves causing, at least in part, an establishment of one or more communication sessions between at least one device and one or more other devices, wherein the communication sessions convey, at least in part, one or more notification messages. The approach also involves processing and/or facilitating a processing of device resource information, device capability information, network resource information, or a combination thereof to determine one or more parameters for generating one or more heartbeat signals to maintain the one or more communication sessions.

Claims

1. A method, comprising:

determining one or more events upon which an establishment of one or more communication sessions over a network between at least one user device and one or more other user devices is based, wherein the communication sessions convey, at least in part, one or more notification messages of the one or more events, wherein the one or more events include a subscription by the one or more other user devices to media objects captured by the at least one user device, and one or more edits on the media objects made by the one or more other user devices;

determining the one or more notification messages to be successful;

confirming successful delivery of the one or more notification messages to the at least one user device and the one or more other user devices;

processing device resource information, device capability information, network resource information, or a combination thereof to determine one or more parameters for generating one or more heartbeat signals to maintain the established one or more communication sessions; and

causing a first iteration of a keep-alive request at a first frequency and a next iteration of the keep-alive request at a second frequency that is lower than the first frequency to reduce a network utilization,

wherein the confirmation of successful delivery of the one or more notification messages is based on the one or more events.

2. A method of claim 1, further comprising:

increasing a frequency of the one or more heartbeat signals when the one or more communication sessions get dropped,

wherein the one or more communication sessions support bi-directional communications, multi-directional communications, or a combination thereof between the at least one user device and the one or more other devices.

3. A method of claim 2, further comprising:

determining one or more available communication networks;

determining one or more estimated power consumption values for the one or more communication sessions conducted over the one or more available communication networks;

ranking the one or more estimated power consumption values in order of magnitude; and

establishing the one or more communication sessions over the communication network having the lowest magnitude of estimated power consumption,

wherein the one or more communication sessions get dropped due to one or more failures on a cloud service platform, on one or more administrative functions, on one or more administrative policies.

4. A method of claim 1, further comprising:

when the media objects are taken and placed in a source media object folder shown a user interface of the at least one user device, causing a population of the media objects in one or more other media object folders shown on one or more other user interfaces of the one or more other user devices; and

in response to a write access to the media objects shown in the one or more other media object folders, reflecting the write access to the media objects is shown in the source media object folder,

wherein the one or more notification messages are triggered by occurrence of the one or more events, and the determination of the one or more events causes, at least in part, a first application configured to establish the one or more communication sessions to be activated.

5. A method of claim 4, further comprising:

subscribing to the one or more notification messages by way of a second application; and

delivering the one or more notifications to the second application based, at least in part, on a determination of the conveyance of the one or more notification messages and the subscription.

6. A method of claim 4, wherein the one or more events further include one or more of an incoming network request, an outgoing network request, a response message, a timed event, or a combination thereof.

7. A method of claim 6, wherein the first iteration of the keep-alive request has a maximum payload of a predetermined number of bytes up and down.

8. A method of claim 7, wherein the next iteration of the keep-alive request is by way of a Transmission Control Protocol (TCP) handshake.

9. A method of claim 4, further comprising:

in response to the population, a notification of the media objects in the one or more other media object folders for one or more users of the one or more other user devices to access.

10. A method of claim 1, further comprising:

determining an occurrence of the one or more heartbeat signals at a first time interval;

determining that one or more of the established one or more communication sessions have ceased; and

determining an occurrence of the one or more heartbeat signals at a second time interval that is greater in frequency than the first time interval.

11. A method of claim 1, further comprising:

determining an occurrence of the one or more heartbeat signals at a first time interval;

determining that one or more of the established one or more communication sessions have ceased; and

determining an occurrence of the one or more heartbeat signals at a second interval that lesser in frequency than the first time interval.

12. A method of claim 1, wherein the one or more heartbeat signals communicate one or more commands to the at least one of the at least one user device and the one or more other user devices, and the one or more heartbeat signals communicate one or more responses to the one or more commands, the method further comprising:

determining that one or more of the one or more heartbeat signals have ceased;

queuing and ranking one or more commands based on a predetermined priority;

communicating the one or more commands in order of the ranking upon re-establishment of the one or more heartbeat signals; and

deleting one or more of the commands determined to be in the queue for a period of time greater than a threshold value.

13. A method of claim 1, wherein the second frequency is a value based on a global minimum frequency data.

14. A method of claim 1, wherein the events start the one or more communication sessions, the communication sessions being asynchronous.

15. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

cause, at least in part, at least one determination of one or more events upon which an establishment of one or more communication sessions over a network between at least one user device and one or more other user devices is based, wherein the communication sessions convey, at least in part, one or more notification messages of the one or more events, wherein the one or more events include a subscription by the one or more other user device to media objects captured by the at least one user device, and one or more edits on the media objects made by the one or more other user devices;

determine the one or more notification messages to be successful;

cause, at least in part, a confirmation of successful delivery of the one or more notification messages to the at least one user device and the one or more other user devices;

process device resource information, device capability information, network resource information, or a combination thereof to determine one or more parameters for generating one or more heartbeat signals to maintain the established one or more communication sessions; and

cause a first iteration of a keep-alive request at a first frequency and a next iteration of the keep-alive request at a second frequency that is lower than the first frequency to reduce a network utilization,

wherein the confirmation of successful delivery of the one or more notification message is based on the one or more events.

16. An apparatus of claim 15, wherein the apparatus is further caused to:

determine one or more events upon which the establishment of the one or more communication sessions is based,

wherein the determination of the one or more events causes, at least in part, a first application configured to establish the one or more communication sessions to be activated.

17. An apparatus of claim 16, wherein the apparatus is further caused to:

cause, at least in part, a subscription to the one or more notification messages by way of a second application; and

cause, at least in part, the one or more notifications to be delivered to the second application based, at least in part, on a determination of the conveyance of the one or more notification messages and the subscription.

18. An apparatus of claim 15, wherein the apparatus is further caused to:

cause, at least in part, the one or more heartbeat signals to occur at a first time interval;

determine one or more of the established one or more communication sessions have ceased; and

cause, at least in part, the one or more heartbeat signals to occur at a second time interval that is greater in frequency than the first time interval.
