Abstract: A security broker (SB) that provides network based authorization of secure VoIP services, triggered upon attempted user access. The security broker (SB) intercepts a SIP transaction during session setup to transmit a network based security challenge to a SIP application attempting to access (secure) IP based services. A network based security challenge is transmitted to a participating SIP application on both the origination and termination legs of a SIP transaction. The network based security challenge prompts a SIP application to return subscriber authorization/authentication credentials (e.g. a username/password combination). If credentials returned by the SIP application are valid, the security broker (SB) authorizes the network to permit session completion, and access to secure IP services is granted.

Abstract: A secure messaging interface enables submission of messages to a messaging gateway via secure means over TLS. A destination mobile device(s) is notified of a pending secure message, and holds the secure message until it is retrieved by an authorized mobile device. The messaging gateway also provides push services for sending data to wireless devices. The secure messager enables sending devices to apply security to an individual message. Sending devices may include, e.g., an enterprise administration server; messages routed through an messaging gateway (MGW) portal; an user messaging application; or a user through a handset. The secured messages may include content as available today across any messaging protocol such as text, audio, video, binaries and images.

Abstract: A method enabling a mobile/non-mobile device to perform location-based message filtering against a proposed list of message recipients. Identifiers indicating location characteristics are embedded in the body of a message prior to transmission. Following message transmission, location characteristics are identified/extracted from a location filtered message by a location filtering engine. Location characteristics may indicate a geographic location (e.g. address, zip code, etc.), a POI, or a boundary centered at a geographic location/POI. The location filtering engine attains location information for each device referenced in a proposed distribution list. Attained location information for each device is compared against location characteristics extracted from a corresponding location filtered message. A formal distribution list is compiled, containing all devices in the proposed distribution list with location information matching location criteria embedded in the corresponding filtered message.
