System and method for subscribing for internet protocol multimedia subsystems (IMS) services registration status
View Patent ↗A system and method that allows mobile device applications to receive changes in registration status from application services that are accessed via an Internet Protocol Multimedia Subsystem (IMS). Applications on a mobile device subscribe to receive notifications of changes in registration status for requested services. When a change to the registration status of a service occurs, a notification message is transmitted to the application on the mobile device. Notifications of changes in status are thereby received by each application on a per-application-service basis. In some embodiments, when a request to register with an application service fails, the corresponding notification message includes a reason for the failure. In some embodiments, notification messages are originated by a registration manager that operates in the IMS and transmitted to an IMS client operating on a mobile device. In some embodiments, notification messages are originated by each application service and transmitted directly to subscribed applications.
1. A computer-implemented method in a mobile device to receive service notifications from registered application services that are accessed via an Internet Protocol Multimedia Subsystem (IMS), the method comprising:
at the mobile device, requesting, via an IP multimedia subsystem (IMS), registration of at least one application on the mobile device with multiple associated application services;
receiving, on the mobile device, multiple notifications from the multiple application services,
wherein each of the notifications indicate, on a per-application-service basis, the status of the corresponding application service,
wherein at least one of the notifications indicates a failure of the corresponding application service and an indication of a reason for the failure of the corresponding application service, and
wherein each notification is received by the corresponding application on the mobile device for which the notification is intended; and
registering the application with one or more different application services in response to determining that the received notification indicates that the registration is terminated, or
halting operation of the application on the mobile device in response to determining that the received notification indicates that the registration is terminated.
2. The computer-implemented method of claim 1 , wherein the multiple notifications include an indication of whether each requested registration is active or terminated.
3. The computer-implemented method of claim 1 , further comprising deregistering the corresponding application on the mobile device if the received notification indicates that the registration is terminated.
4. The computer-implemented method of claim 1 , wherein at least one application service is a location-based service.
5. The computer-implemented method of claim 1 , wherein at least one application service is a multimedia telephony service.
6. The computer-implemented method of claim 1 , wherein at least one application service is a video conferencing and sharing service.
7. The computer-implemented method of claim 1 , wherein at least one application service is an instant messaging and presence service.
8. A computer-implemented method of providing application service status notifications to mobile devices for services that are accessed via an Internet Protocol Multimedia Subsystem (IMS), the method comprising:
receiving, from a plurality of mobile devices, requests to receive notifications of status changes of application services accessed by the plurality of mobile devices via an IP Multimedia Subsystem (IMS);
receiving at least one notification from application services, each notification providing a status of a corresponding application service;
identifying mobile devices that are associated with the application service in each received notification; and
for each received notification:
providing the received notification to the identified mobile devices that are associated with the application service,
wherein the notification indicate, on a per-application-service basis, the status of the application service and an indication of a reason for the status of the application service; and
in response to determining that the received notification indicates that the registration is terminated,
registering the application on the mobile device, or
halting operation of the application on the mobile device.
9. The computer-implemented method of claim 8 , wherein the received status indicates whether the requested application service is active or terminated.
10. The computer-implemented method of claim 8 , wherein at least one application service is a location-based service.
11. The computer-implemented method of claim 8 , wherein at least one application service is a multimedia telephony service.
12. The computer-implemented method of claim 8 , wherein at least one application service is a video conferencing and sharing service.
13. The computer-implemented method of claim 8 , wherein at least one application service is an instant messaging and presence service.
14. The computer-implemented method of claim 8 , wherein the reason for the received status is contained in an extensible markup language (XML) document.
15. A non-transitory computer-readable medium storing instructions that, when executed by a processor of a mobile device, cause the mobile device to execute a method to receive changes in registration status from application services that are accessed via an Internet Protocol Multimedia Subsystem (IMS), the method comprising:
receiving, on the mobile device, a request to register at least one application on the mobile device with at least one application service accessed via an IP multimedia subsystem (IMS);
transmitting, via the IMS, the registration request to at least one associated application service;
receiving, by the at least one associated application on the mobile device, one or more notifications regarding the requested registration, the one or more notifications indicating, on a per-application-service basis, the registration status of each application service and an indication of a reason for the registration status of the corresponding application service; and
registering the application on the mobile device with one or more different application services in response to determining that the received notification indicates a terminated registration, or
halting operation of the application on the mobile device in response to determining that the received notification indicates a terminated registration.
16. The non-transitory computer-readable medium of claim 15 , wherein the reason for the registration status is contained in an extensible markup language (XML) document.
17. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the mobile device to deregister the associated application on the mobile device in response to determining that the received notification indicates a terminated registration.
18. The non-transitory computer-readable medium of claim 15 , wherein at least one application service is a location-based service.
19. The non-transitory computer-readable medium of claim 15 , wherein at least one application service is a telephony service.
20. The non-transitory computer-readable medium of claim 15 , wherein at least one application service is a video conferencing and sharing service.
