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.

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： 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： 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： Group communications methods and apparatus are described. In particular, methods for granting a mobile device access to a communications resource, e.g., the right to transmit data, associated with a group are described. User requests for the communications resource are suppressed by the corresponding mobile device, for periods during which the communications resource has been granted to another mobile device. A mobile device may store a suppressed user request so that a resource request signal may be transmitted after the communications resource has been released by the mobile device that was previously granted the resource. In this manner requests that cannot be granted are not transmitted, increasing communications efficiency as compared to systems where requests are not suppressed at the mobile devices. A priority scheme is used in some embodiments to determine whether or not a request should be suppressed while another device has been granted the communications resource.

摘要： Methods and apparatus related to message compression/decompression are described. A compressed message is generated by indicating what changes are to be made to a previous message to produce the message sought to be transmitted. The required change, in the form of at least one command and corresponding parameter, is transmitted as a compressed version of the message being communicated. This approach takes advantage of the fact that messages sent over time often include much of the same message content and only one or a few fields may have changed. The techniques are general and involve including a command in the compressed message along with at least one parameter. The command indicates processing to be performed on a previous message to generate the uncompressed message. The parameter may be, e.g., data to be inserted into the previous message or specify a location in the previous message where the change is to be made.

摘要： Aspects describe spectrum authorization, access control, and configuration parameters validation. Devices in an ad-hoc or peer-to-peer configuration can utilize a licensed spectrum if the devices are authorized to use the spectrum, which can be determined automatically. Aspects relate to distribution of authorization tickets by an authorization server as a result of validating a device's credentials and services to which the device is entitled. An exchange and verification of authorization tickets can be performed by devices as a condition for enabling a validated wireless link using the spectrum.

摘要： Described herein are mechanisms and methods that facilitate utilizing a base station as a regional mobility agent (e.g., regional home agent, regional foreign agent, and/or the like). Thus, a base station can have functionality embedded therein that enables the base station to create tunnels with other base stations and selectively direct data intended for a wireless terminal to those base stations. Such base stations can then transmit the data to the wireless terminal.

摘要： Methods and apparatus for compressing messages used to support mobile communications are described. After transmission of a first mobile IP message which may be a conventional mobile IP message, a compressed mobile IP message is transmitted. The compressed message includes a new “compressed message” indicator and information which is to replace information in the previous message or to be added to the previous message to construct a new message. In some embodiments, the compressed message includes a mask field, e.g., a sequence of bits, each bit corresponding to one field of a standard registration request message or binding update message. If the mask flag bit corresponding to a field is set, it indicates that the compressed message includes information to replace the content in the corresponding field of the previous message or to be added to the previous message as a field corresponding to the asserted bit.
