System and method for subscribing for internet protocol multimedia subsystems (IMS) services registration status

摘要

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.

主权项

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, andwherein 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.
