摘要： 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.
摘要翻译：提供了一种用于使用快速认证建立网络通信会话的系统和方法。在网络系统中，客户机或用户设备可以使用完全认证与服务器建立通信会话。如果会话被中断或中止，并且请求恢复会话，则可以将先前建立的会话的会话标识符与所请求会话的会话标识符进行比较。如果检测到匹配，则可以使用快速认证（或重新认证）过程恢复会话，使得会话更有效和方便地恢复。例如，即使当第一会话和恢复的第二会话具有不同的认证层，不同类型的网络接口和/或不同的位置时，也可以执行快速认证。因此，诸如TLS会话的会话可以在诸如802.1X，PANA或基于蜂窝的系统的多个定义的认证协议或技术中恢复功能。

摘要： 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.

摘要： A system and method for network selection procedures for simultaneous network connectivity through multiple accesses comprises obtaining stored and registered PLMNs, determining whether PLMNs are both stored PLMN for access technology type Ai and registered PLMN, when no PLMNs are both, performing PLMN selection using a standard procedure, when only one PLMN is both, determining whether the PLMN satisfies a condition, and when the PLMN satisfies the condition, attempting to connect to the PLMN, and when more than one PLMN is both, creating a set of PLMNs, selecting one PLMN that satisfies the condition, from the set PLMN, attempting to connect to the selected PLMN, and when attempting to connect fails, removing the selected PLMN from the set, and selecting another PLMN. In one aspect, the PLMN that minimizes changes is selected. In one aspect, the PLMN that provides access to a larger number of access technologies is selected.

摘要： 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. Accordingly, the mobile node may transition from any of the subnetworks to another subnetwork without communicating to the home agent information about the transition and without communicating to the DTA information about a security association between the mobile node and the home agent.

摘要： A system for media independent handover using a session identifier in which a session identifier is used for identifying a media independent handover registration session across different MIH transport instances between a pair of communicating MIHFs. A point of service maintains a single registration state for a mobile node across the multiple transport instances. A session identifier is assigned by a point of service at the time of initial registration, and is valid only during the lifetime of the registration. A registration state includes local handles to transport instances that are used when sending and receiving media independent handover messages related to the registration.
