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 two or more associated services; receiving, on the mobile device, two or more notifications from the two or more services,
wherein the received notification indicates the status of the corresponding service,wherein at least one received notification indicates a failure of the corresponding service and information regarding a reason for the failure of the corresponding service, andwherein the received notification is received by the application for which the notification is intended; and in response to determining that the received notification indicates that the registration has failed, taking at least one of the following actions (a), (b), (c), or (d):
(a) displaying an indication as to whether the failure is temporary in nature;(b) displaying an indication that the failure will remain in effect until a specified action is taken;(c) registering the corresponding application with one or more different services; or(d) halting operation of the corresponding application on the mobile device. |
