摘要： The claimed subject matter relates to performing routing in a wireless communications system. In more detail, each device associated with a wireless packet-switched network may not be aware of an identity and/or address of a particular point of attachment with respect to a wireless terminal. A data packet that should be provided to a particular point of attachment can be initially directed to a wireless terminal or a one-hop multicast address, for instance. Thereafter, the data packet can be encapsulated in a frame format and identity of the particular point of attachment can be provided in such frame. The frame can thereafter be routed to the point of attachment.

摘要： The claimed subject matter relates to systems and methods for roaming in a wireless communications environment. A method for roaming between networks is provided in one aspect. This includes receiving a request for network access at a visited network and receiving a profile from a home network in response to the request. Upon receiving the profile, selectively offering services to one or more access terminals based at least in part on the profile.

摘要： Aspects relate to allowing peer nodes that establish a communication through a home agent to move that session to a directly connected link. Thus, the directly connected nodes can exchange packets natively without encapsulation. Further aspects allow a node that does not have any home agent entity to switch from a local network to a global network without losing ongoing sessions.

摘要： Various embodiments relate to wireless communications devices which support multiple modes of peer discovery operation. In some embodiments, the multiple modes of peer discovery operation include different modes which are associated with different rates of transmitting peer discovery information. In some embodiments, the multiple modes of peer discovery operation include different modes which are associated with different rates of monitoring peer discovery information. In various embodiments, a communications device determines whether or not to switch between different peer discovery modes of operation as a function of proximity to a location of interest. Proximity determinations may be, and sometimes are, based upon geographic position comparisons. Alternatively or in addition, proximity determinations may be, and sometimes are, based upon received signal strength measurements.

摘要： Session signaling register message transmission methods and apparatus well suited for use in a communication system which supports mobile nodes capable of moving between domains and access nodes in a domain are described. Broadcasting of session signaling register messages is supported to reduce the number of registration messages which need to be transmitted between a mobile node and an access node. A paging and location server is used to reduce the number of session signaling register messages transmitted between domains. A visiting node registers with a paging and location server. The session signaling address of the paging and location server being used by a visiting mobile node is registered with the visiting node's home session signaling server. As the visiting node moves between access nodes in the visited domain the paging and location server it uses remains the same eliminating the need to update the home session signaling servers.

摘要： The claimed subject matter relates to configuring a host device through utilization of MMP, which is a protocol that is based upon MIP but not associated with several deficiencies associated therewith. In particular, a wireless terminal can be configured to run MMP and send messages that conform to MMP over a wireless link. A base station can be configured to act as a DHCP server. The base station can provide configuration information to host device by way of DHCP.

摘要： A mobile communications system that uses IP packets to transmit data between end nodes, such as mobile devices, is described. In order to facilitate session establishment, maintenance, security, and handoff operations, access nodes through which end nodes communicate with one another include a session signaling server module and a mobility agent module. The session signaling server module may be implemented as a SIP server while the mobility agent module may be implemented using Mobil IP signaling. The mobility agent and SIP server within an access node are identified using a single shared identifier, IP address. The same security method and common secret may be used to provide security with regard to both mobile IP messages and SIP messages. Sessions admission decisions and resource allocation for admitted sessions can also take place internally to the access node of this invention without need for signaling to external elements.

摘要： Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.

摘要： Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.
