Abstract: Methods, systems, and apparatuses for IMS guest registration for non-IMS users are provided. The method may be performed by receiving a registration request from a non-IMS user for access to an IMS network, the registration request indicating a domain name of a non-IMS system; determining whether the domain name indicated by the registration request matches a wildcard identifier, wherein the wildcard identifier may be indicative of a non-IMS system authorized to access the IMS network; and initiating a guest registration process if the domain name matches the wildcard identifier. The non-IMS user is authenticated in the IMS network via a non-IMS authentication entity.

Abstract: A method and apparatus for reducing network resources from presence notification traffic. This invention assumes a standard presence architecture of presentities, watchers, and a presence server involved in pushing (notifying) watchers when a presentity's state changes. In addition, there exists a source of past communication data (or other data providing a means of prioritization) for a subscriber. The presence server determines, based upon the past communication data (or other prioritization data) of a subscriber, whether to notify about the presentity's state change immediately or to wait on notifying the watcher until either additional notify messages also need to be sent (and can be bundled in one message) or a guard timer expires. In this fashion, the presence information that the subscriber cares about is delivered in real time while the information that is less important to the subscriber consumes less network resources.

Abstract: A method for provisioning a peering relationship between the multimedia networks in a telecommunications system. The method comprises registering a customer with at least one of the multimedia networks; constructing the customer's mapping and routing data (including initial filter criteria) within each of the networks; synchronizing the customer's mapping and routing data between the multimedia networks; and storing the customer's mapping and routing data in a database in each of the multimedia networks. Further, the method results in network selection using the customer's mapping and routing data.

Abstract: A method and apparatus for identifying a caller who does not provide caller identification on an unanswered call. The caller is asked to record his/her name (or some other characteristic utterance). If the call is unanswered, the record is retained and can be accessed by the called party when that party requests his/her stored voice mail. Advantageously, even on unanswered calls, the identity of the caller can be presented to the called party when that called party requests stored voice mail messages, even if the calling party has private service.

Abstract: A scalable policy-based Web Services security architecture that incorporates a combination of authentication with service discovery, evaluation of access policies, and capturing the result of this process in a signed, security token, thus, allowing efficient processing for each service request in a secure manner. A method for securing a Web Service comprises discovering the Web Service in response to a service request and determining an access policy for the Web Service separately from the actual service based on the service request.
