Abstract: A system and method for allowing mobile devices to simultaneously access a Subscriber Identity Module (SIM) are disclosed. The SIM contains a wireless transceiver, and the SIM may be located within a mobile phone, or it may be a stand-alone device. The mobile devices use a wireless protocol, such as Bluetooth, to retrieve identification information from the SIM. The devices then use this identification information to connect to a wireless communications network, such as a wireless local area network. Through this network the devices will be able to access the Internet. The SIM will never need to be removed and inserted from one device to another, and multiple devices can use the SIM simultaneously. Thus, the mobile phone will work regardless of whether other devices are also using the SIM.

Abstract: In a network that executes a link state routing protocol, a network node receives periodic disseminations of link state information from other network nodes. The link state information includes neighboring node identity and link cost metrics. The network node calculates the initial routing paths based on the received link state information by using a link state routing algorithm. It then adapts the calculated path based on both the current link state information and past link state information through a reinforcement learning process. The network node then selects a routing path to each destination node based on the adaptation and updates the routing table accordingly.

Abstract: A system and method are provided for establishing a network communication session using fast authentication. In a network system a client or user device may establish a communication session with a server using full authentication. If the session is interrupted or discontinued and resumption of the session is requested, a session identifier of the previously established session may be compared to the session identifier of the requested session. If a match is detected, the session may be resumed using a fast authentication (or re-authentication) procedure such that the session is resumed more efficiently and expediently. Fast authentication may be performed, for example, even when the first session and the resumed second session are of different authentication layers, different types of network interfaces and/or different locations. Thus, a session, such as a TLS session, may resume functionality among multiple defined authentication protocols or technologies such as 802.1X, PANA or cellular based systems.

Abstract: A method for distributing and conditioning IP traffic for mobile networks based on differentiated services, wherein edge/border routers are only required to maintain QoS profiles for related mobile stations. A new IP address or a new service level subscription or service level agreement of an mobile station is only sent to related edge/border routers. As a result, unnecessary IP traffic is significantly reduced. The routers in accordance with methods of the invention disregard the contents of an IP payload and therefore all of the IP addresses that a mobile station may posse. A mobile station is permitted to enter into a domain and obtain a desired quality of service (e.g., Gold or Standard service) without the need to maintain the service while moving through the domain.

Abstract: Methods and systems are provided for facilitating intra-domain mobility. A first network or domain includes a home agent or SIP proxy of a mobile node. A second network includes two or more subnetworks and at least one dynamic tunneling agent (DTA). Each subnetwork includes an associated subnet agent. To communicate, the mobile node first registers with a subnet agent, receives a local care-of-address and a global care-of-address, and then registers with a DTA. The local care-of-address received from the subnet agent may enable communication with the mobile node without determining a specific route to the mobile node. The global care-of-address received from the subnet agent may include the address of the DTA with which to register. On registering with the DTA, the DTA may provide the mobile node with a unique, globally reachable global care-of-address, which the mobile node may then forward to a home agent, SIP proxy, or a correspondent node.

Abstract: The Dynamic Registration and Configuration Protocol (DRCP) provides a framework for registering and passing configuration information to roaming mobile hosts. DRCP is compatible with DHCP can switch to using DHCP protocol if only DHCP servers are present in the network. Most importantly, DRCP allows rapid configuration by moving address consistency checking from the critical path. Other novel features of DRCP allow: a) clients to know when to get a new address independent of the layer-2 access technology, b) efficient use of scarce wireless bandwidth, c) clients to be routers, d) dynamic addition or deletion of address pools to any DRCP node, and e) message exchange without broadcast.

Abstract: Integrated mobility management mechanisms monitor a mobile host's degree of mobility and the applications it executes. Mobile hosts move between wireless-access, micro-mobility domains interconnected through a backbone network. While the mobile host is stationary, MIP-LR and SIP systems operate to ensure TCP and RTP/UDP packets, respectively, traveling to/from the mobile host are properly routed through the backbone to the host's current domain. An MMP system routes packets through this domain. As the host moves within a domain, the MMP system updates the domain routing to the mobile host's new location. As the mobile host moves between domains, the host obtains a new IP address and the MMP system establishes routing within the new domain to the mobile host's new location. In addition, the MIP-LR and SIP systems activate to ensure the TCP and RTP/UDP packets, respectively, are automatically re-routed through the backbone to the new domain.

Abstract: This is a 32-bit combined arithmetic unit and stack processor (designated as the ASP chip) designed to be a simple, flexible, yet powerful building block for a high level language computer. The ASP is a 3-micron CMOS chip which has run high level programs at 12.5 MHz. When combined with the right hardware and compiler, it will run procedural language programs efficiently. It requires extra hardware to build a complete system, so it is to be mainly where speed is critical; but, employs greatly simplified hardware and software designs. A basic ASP combines arithmetic and stack manipulation functions and is capable of performing 227 different instructions to implement the high level language. A minimum of two ASPs are required to construct a stack-oriented high level language computer.
