Abstract: Systems and methods according to aspects of the invention verify requests for information over a network. Computing devices communicating over a network transmit numerous signals with various types of information including spatial information, temporal information, device-specific information, and transmission specific information. This information may be used to generate statistical records of valid request for information. Various combinations of these signals may be used to determine whether a request for information is a valid request based on the statistical records associated with the signals. Where a request for information has been verified, the system and method may provide the information. Where the request for information has not been verified, the system and method may deny the request for information. Thus the system and method may be used to prevent and block scraping and spamming attacks.

Abstract: In order to carry out actions such as setting up a call from an entity in the address realm of one middlebox to an entity in the address realm of another middlebox, then a middlebox control node such as a call server is used. Previously, the middlebox control node has needed to have pre-configured information about all the middleboxes and which address realms they are associated with. The present invention provides one or more middlebox-identity-providing nodes which are separate from the middlebox control node, and which are more directly connected to the end users of the service than the middlebox control node. This provides greater flexibility in network design and removes the need for middlebox information to be pre-configured at the middlebox control node. Instead, this information is sent to the middlebox control node, as part of signalling messages, from middlebox-identity-providing nodes.

Abstract: Aspects of the invention pertain to transmitting packet data across a computer network. The packets may be sent via one or more distinct routes from a source to a destination. Each route may employ multiple routers disposed along the network. Non-colliding routes are determined by transmitting pairs of probe packets along the routes. A first probe packet has a maximal length, and a second probe packet has a minimal length. Depending on the order of arrival of the probe packets, the system determines whether two transport layer ports at the destination device collide. If there is a collision, then the system searches for a set of non-colliding ports. Once the non-colliding ports are determined, application data may be sent as packets along the different routes to those ports.

For newly-encountered WLANs, the mobile device may also automatically create and store a wireless network profile associated with the WLAN that provides the aggregator service.

Abstract: For purposes of servicing emergency calls, such as 911 calls, a telephone number is associated with each edge router port used to provide IP service to a customer premise location. A telephone number is associated with the edge router port and the corresponding customer location. The telephone number and location information are stored in a database used for providing emergency calling party location information. When a switch used for routing IP calls detects a telephone call to an emergency call center it determines the edge router port from which the call was placed and the telephone number associated with the port for emergency call purposes. The call is then forwarded to the emergency call service center with the determined telephone number being supplied as the calling party number. Performing a lookup operation using the supplied telephone number the emergency service operator determines the location from which the call was placed.

Abstract: Multimedia IMS communications are established by matching callee capabilities with caller preferences and identifying a URI parameter in response thereto. When a session initiation protocol (SIP) request identifying caller preferences for an internet communication session and an identified callee is received (602), a determination is made of whether the identified callee is a registered address of record (AOR) or not (604). If the identified callee is a registered AOR (604), a uniform resource identifier (URI) parameter and a globally routable user agent URI (GRUU) associated with callee capabilities are identified (608, 612, 614). The URI parameter is used to create a modified SIP including the URI parameter (616) for sending (618) to an IMS enabled wireless communication device (120).

The invention resides in the fact that if the client is located behind an address translation device, it determines an approximate expiry time for the temporary binding by successively sending test messages after an increasing wait time until the termination of the binding is detected. This approximate time is then used by being transmitted as the SIP validity period.

Abstract: Call admission control within a wireless network is implemented using a service controller that manages a set of access points. The call admission control (CAC) function for a given access point determines whether the access point has sufficient unused bandwidth to handle an additional call. The service controller makes this determination by monitoring the access points and evaluating certain probability functions and load conditions. In one embodiment, a determination of whether the access point has sufficient unused bandwidth to handle an additional call is a function of two (2) independent probabilities: (i) a probability of an active session moving to the access point from one or more neighbor access points, and (ii) a probability of an idle mobile device already associated with the access point entering into a new active session by initiating an inbound or outbound call.
