Abstract: Methods and apparatuses are provided that facilitate compressing packet headers for communicating among access points. An access point can advertise compression profiles to one or more disparate access points, and the one or more disparate access points can select at least one compression profile for compressing/decompressing packets related to the one or more disparate access points and/or devices communicating therewith. The one or more disparate access points can notify the access point of the selected compression profile, a compression context identifier, and/or static data related to identifying associated packets. In this regard, the access point can compress packets that have the associated static data according to the compression profile and compression context identifier. Similarly, the access point can decompress packets from the one or more disparate access points based on the compression context identifier.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for semi-centralized routing. One of the methods includes receiving one or more routes and determining that a received route identifies a new set of paths different from each routing path group in a maintained set of routing path groups. A new routing path group is created that corresponds to the new set of paths. The new routing path group is assigned an identifier of the routing path group. The new routing path group is converted to a corresponding new flow path group. A flow path group that was converted from the routing path group is replaced on a network device with the converted new flow path group.

Abstract: A system and method for establishing communications channels between and among peers in a peer-to-peer networking environment. Pipes may be used as communication channels for sending and receiving messages and other data between services or applications over input and output endpoints. Pipes may be asynchronous, unidirectional, stateless and unreliable. Bidirectional pipes may also be supported. Pipes may have ends that may be moved around and bound to different peers at different times. Point-to-point and propagate pipes may be supported. Pipes may connect peers that have a direct physical link and peers that do not have a direct link. Peers may communicate through pipes without knowing on which peer a pipe endpoint is bound. A message is sent to all peer endpoints currently connected (listening) to the pipe. The set of connected endpoints may be obtained from a pipe service using a pipe binding protocol.

Abstract: Methods, devices, and systems are provided for preserving connections, especially in a SIP environment. More specifically, the connection preservation techniques presented in this document enhance the RFC 4028-based session refresh approach in order to provide media connection preservation for calls that experience end-to-end signaling loss or refresh failures. Specifically, participants on a call can continue to exchange media despite the loss of control at the SIP signaling plane.

Abstract: A user initiates a request for determination of position of a mobile device in an area where there is no GPS signal. The position of the mobile device is determined by using cell tower triangulation methods using the wireless operator network. If the mobile device is in communication with a wireless local area network access point, the mobile device provides information about the address of the wireless local area network access points within range and the signal strength of the wireless access points. The server then stores the determined position in a database in connection with each address and signal strength provided by the wireless local area network access point. Thus the position of the wireless local area network access point has now been recorded and can be used in the future to determine the position of a mobile device.

Abstract: Methods and apparatuses are provided that facilitate establishing multiple sub-connections between a correspondent node (CN) and a mobile node (MN), through a home agent (HA) to provide multipath functionality over multiple MN interfaces. The MN can connect to multiple networks using multiple MN interfaces, receiving care-of addresses (CoA) at each network. The MN can establish multiple connections to the CN specifying, to the HA, a different 5-tuple (or n-tuple) for each connection. The different 5-tuple can include a different port number related to a home address assigned by the HA. Also, bindings at the HA can be updated to associate the different 5-tuple with a CoA of one of the multiple MN interfaces. In this regard, the HA can route packets to the MN from the CN based at least in part on determining the HoA port number in the packet associated with the CoA of an MN interface.

Abstract: Provided are a cognitive radio (CR) cooperative spectrum sensing method and a fusion center (FC) performing CR cooperative spectrum sensing. The CR cooperative spectrum sensing method includes receiving, at an FC, local spectrum sensing information about a predetermined frequency band from each of N secondary users (SUs) in a predetermined zone, determining, at the FC, the optimum number of SUs for determining whether the predetermined frequency band is being used by a primary user (PU) on the basis of the received local spectrum sensing information, and performing cooperative spectrum sensing on the basis of local spectrum sensing information received from the optimum number of SUs in the predetermined zone. The method is implemented by the FC. Accordingly, the method and FC find how many SUs are needed to determine that a frequency of a PU is being used in a corresponding-channel situation, thereby enabling efficient communication.

Abstract: In an apparatus for connection control between two terminals, a communication unit transmits or receives a connection control signal to or from the terminals. A storage stores media format information usable on the two terminals, which are to be supplied with the media format information on media formats converted by a media format converter. A media format information supplementing unit references the media format information storage, based on the connection control signal received from the terminal, and verifies a possible presence of common media format information usable by the terminals to be interconnected. If there is no common media format information, predetermined media format information is supplemented to the connection control signal, and a resulting connection control signal is delivered to the communication device. Thus, media negotiation may be made even when media formats usable on the two terminals differ from each other.

Abstract: A network includes reservation agents for reserving bandwidth for communication sessions and swapping bandwidth reservations from one communication session to another communication session. After a swap, the recipient communication session proceeds using the bandwidth originally reserved for the donor communication session, while the donor communication session no longer utilizes that bandwidth reservation. By swapping bandwidth reservations, a network may more efficiently use bandwidth in an environment where bandwidth is a limited resource.
