Abstract: A network element is configured to receive a first packet from a first eNodeB (eNB) of the packet network via a first secured X2 link. The network element decrypts the first packet to reveal a second packet encapsulated within the first packet. The network element determines a second secured X2 link associated with a second eNB as an intended recipient of the second packet. The network element encrypts the second packet to generate a third packet and transmits the third packet to the second eNB via the second secured X2 link. The network is coupled to various eNBs of the packet network via various secured X2 links, respectively.

Abstract: According to one aspect, a mobility gateway device (MGW) receives a request from a wireless local area network (WLAN) controller of a WLAN for accessing the Internet or a packet core network, where the request is originated from a user equipment communicatively coupled to the WLAN. In response to the request, the MGW is configured to determine whether there is an active session associated with the UE over a wireless wide area network (WWAN). If so, the MGW assigns an IP address to the UE that was assigned to the UE during the active session of the WWAN. The assigned IP address is used by the UE to access the Internet or the packet core network over the WLAN.

Abstract: A node (200) includes a processor (201) for determining neighbor nodes in a routing path to a destination based on a routing table associated with the node (200). The node (200) includes a memory for storing a first authenticated tokens. The node includes a transmitter (203) for transmitting a first request-to-route (RTR) message including an indication specifying information units (IUs) from the first node to the neighbor nodes in a routing path from the first node to the destination. The node (200) includes a receiver (205) for receiving a neighbor reply message from one of the neighbor nodes to the first node which indicates that the neighbor node will route the information units (IUs). The transmitter (203) transmits a second authenticated tokens from the first node to one of the neighbor nodes. The second authenticated tokens are converted into a tradable entity and provide compensation to the neighbor node selected.

Abstract: Peer-A (101) broadcasts a Peer Lookup Query (107) to a Peer Discovery Service (PDS) (105). Peer-A (101) may receive a Peer Lookup Response (109) from any peer having the reachability information including a Time Stamp, and an Initial Sequence Number. Peer-A (101) may subsequently use the Time Stamp and Sequence Number to send session management and session media packets to Peer-B (103). Peer-A (101) and Peer-B (103) reciprocally store message identification including sequence number and timestamp in a local session record contained in a secure memory. At completion of the IP session, both Peer-A (101) and Peer-B (103) will dump the session records from their respective secure memories to a remote Session Log Database (115), via message (117) and message (119), respectively. The remote session DB consolidates the records and uses the temporal and causal relationships between the messages to resolve any data conflicts and recreate the complete session record.

Abstract: Various embodiments are described to address the need for an apparatus and method that improves link layer handoff by addressing the packet-loss problem existing today. An intermediate buffer management layer (IBML) (201, 211) is introduced below layer 3 of an OSI-based communications interface. The IBML buffers copies of OSI layer 3 packets being transmitted via lower layers (205, 215) of the interface and manages the buffer contents using indications the IBML receives from one or more of the lower layers. When the IBML receives an indication that a link layer hard handoff is proceeding, the IBML transfers the presently buffered packets to a corresponding IBML (202, 212) in the target communications interface. This sub-layer 3 buffer transfer enables the target communications interface to reduce packet-loss associated with the hard handoff.

Abstract: A communication system provides for an expedited Mobile Internet Protocol handoff by allowing a mobile station that is engaged in a communication session with a first access network to obtain Internet Protocol connectivity information associated with a second access network via the first access network. A tunnel is then established between the mobile station and the second access network via the first access network based on the Internet Protocol connectivity information and the mobile station obtains Internet Protocol configuration parameters from the second access network via the established tunnel. By obtaining the Internet Protocol configuration parameters associated with the second access network via the first access network instead of waiting until an air interface connection has been established with the second access network, the mobile station may be more expeditiously handed off to the second access network in the event that such a handoff determination is made.
