Method and apparatus for providing device compatibility information
An approach is provided for determining device compatibility using alerts and information spaces. A link redirector receives a request from a device for a required type of service. The link redirector alerts the device compatibility service and the export control interface about the potential request or stores the request information in an information space while searching for a suitable service for the device. Therefore, the device compatibility service and the export control interface can start preparing information about device compatibility and export control before the information is requested by the service determined.
1. A method comprising:
receiving, at a device compatibility service node, an alert indicating a potential device compatibility request potentially originating from a service platform that provides a service, the alert comprising device identification data associated with a client that is requesting to access the service, the potential device compatibility request corresponding to an actual device compatibility request that has not yet been received at the device compatibility service node;
preparing to respond to the potential device compatibility request before the actual device compatibility request is received at the device compatibility service node; and
sending, from the device compatibility service node, the response to the service platform after the actual device compatibility request is received.
2. A method of claim 1 , wherein the alert is received via an information space after a service request associated with the potential device compatibility request is received at the information space.
3. A method of claim 2 , wherein the information space is provided to the device compatibility service node by at least one of signaling, subscription, and implicit two-way communication.
4. A method of claim 3 , wherein the subscription is implemented as a persistent query of the information space.
5. A method of claim 3 , wherein receiving the alert of the potential device compatibility request comprises:
receiving a notification of a change to information in the information space causes at least in part transmission of the changed information to the device compatibility service node; and
querying the information space to retrieve the alert.
6. A method of claim 2 , wherein the information space stores a history of at least one of service requests, potential device compatibility requests, requested services, and device identification data associated with service requests.
7. A method of claim 1 , wherein the alert further comprises a session key associated with the potential device compatibility request, and the session key is included in the potential device compatibility request.
8. A method of claim 1 , wherein the alert is received from a link redirector.
9. A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause a device compatibility service node to at least perform the following steps:
receive an alert indicating a potential device compatibility request potentially originating from a service platform that provides a service, the alert comprising device identification data associated with a client that is requesting to access the service, the potential device compatibility request corresponding to an actual device compatibility request that has not yet been received at the device compatibility service node;
prepare to respond to the potential device compatibility request before the actual device compatibility request is received; and
send the response to the service platform after the actual device compatibility request is received.
10. A non-transitory computer-readable storage medium of claim 9 , wherein the alert is received via an information space after a service request associated with the potential device compatibility request is received at the information space.
11. A non-transitory computer-readable storage medium of claim 10 , wherein the information space is provided to the device compatibility service node by at least one of signaling, subscription, and implicit two-way communication.
12. A non-transitory computer-readable storage medium of claim 11 , wherein the subscription is implemented as a persistent query of the information space.
13. A non-transitory computer-readable storage medium of claim 11 , wherein the device compatibility service node, when receiving the alert of the potential device compatibility request, is further caused to perform at least the following steps:
receive a notification of a change to information in the information space causes at least in part transmission of the changed information to a device compatibility service; and
query the information space to retrieve the alert.
14. A non-transitory computer-readable storage medium of claim 10 , wherein the information space stores a history of at least one of service requests, potential device compatibility requests, requested services, and device identification data associated with service requests.
15. A non-transitory computer-readable storage medium of claim 9 , wherein the alert further comprises a session key associated with the potential device compatibility request, and the session key is included in the potential device compatibility request.
16. A non-transitory computer-readable storage medium of claim 9 , wherein the alert is received from a link redirector.
17. An apparatus of a device compatibility service node comprising:
at least one processor; and
at least one memory including computer program code, 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,
receive an alert indicating a potential device compatibility request potentially originating from a service platform that provides a service, the alert comprising device identification data associated with a client that is requesting to access the service, the potential device compatibility request corresponding to an actual device compatibility request that has not yet been received at the device compatibility service node;
prepare to respond to the potential device compatibility request before the actual device compatibility request is received; and
send the response to the service platform after the actual device compatibility request is received.
18. An apparatus of claim 17 , wherein the alert is received from a link redirector.
19. An apparatus of claim 17 , wherein the alert is received via an information space after a service request associated with the potential device compatibility request is received at the information space.
20. An apparatus of claim 17 , wherein the alert further comprises a session key associated with the potential device compatibility request, and the session key is included in the potential device compatibility request.
