Abstract: Devices, systems and methods are disclosed which relate to analyzing an electronic address book for a change which impacts a service, and updating the service. An analysis engine monitors the electronic address book for changes, then evaluates whether each change impacts a service. If the change does impact a service, a reaction engine applies that change to the service. The change can be a new telephone number for an existing contact, a new group applied to a contact, a new permission for a contact, etc. These changes potentially impact a service such as caller restriction, find me/follow me, photo sharing, etc. The reaction engine applies the change to a network controller ultimately in control of the service.

Abstract: An attribute rule enforcer for evaluating the attributes of a call to add, modify, or delete information in a directory, such as a lightweight directory access protocol (LDAP) directory. The attribute rule enforcer determines if the attributes of the call comply with predetermined rules governing the directory's content. The directory attribute rule enforcer may be located at the front end of the directory's access server, and intercepts calls to the directory access server. If the directory attribute rule enforcer determines that the attributes of a call complies with the rules governing the content of the directory, it will forward the call to the directory's access server for action. If, on the other hand, directory attribute rule enforcer determines that the attributes of a call do not comply with the rules governing the content of the directory, the attribute rule enforcer will reject the call. Further, it may forward an appropriate error message to the source of the call.
