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.
摘要翻译：描述组通信方法和装置。具体地，描述了用于授予移动设备访问通信资源的方法，例如与组相关联的发送数据的权利。通信资源的用户请求被相应的移动设备抑制，在此期间通信资源被授予另一个移动设备。移动设备可以存储抑制的用户请求，使得在先前被授予资源的移动设备已经释放了通信资源之后可以发送资源请求信号。以这种方式，与不在移动设备处抑制请求的系统相比，不传送不能被授权的请求不会传输，从而提高通信效率。在一些实施例中使用优先级方案来确定在另一设备已经被授予通信资源的同时是否应该抑制请求。

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.
摘要翻译：描述用于存储，操纵，检索和转发用于支持与一个或多个终端节点（例如，移动设备）的通信会话的状态（例如，上下文和其他信息）的方法和装置。各种特征涉及在切换操作期间控制从第一接入节点到第二接入节点的状态传输的移动节点，从而消除在切换期间在第二接入节点和第一接入节点之间传输的状态转移消息的任何需要。本发明的其它特征涉及使用核心网络节点来存储状态信息。存储在核心节点中的状态信息可以在移动节点在切换期间不发送状态转移消息的情况下由接入节点访问和使用，例如，因为与第一接入节点的通信丢失或者因为不支持这样的消息。

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： Signal, e.g., message, security techniques are described for wireless systems. A first signal is received by an access node via a wireless link. The signal includes a first authenticator that was generated by the transmitting device, e.g., wireless terminal. The access node determines from an attribute of the signal at least some information known to both the access node and transmitting device but which was not transmitted as part of the message content. The determined information was used by the wireless terminal in generating the first authenticator. The access node sends at least a portion of the first signal including the first authenticator and the determined information to another entity. The entity compares the first authenticator to a second authenticator it generates from the determined information and a secure key which it shares with the transmitting device to determine if the first and second authenticators match.

摘要： Location update techniques are described. A dormant mobile node updates its location information by sending a first message over a wireless link to an access node. The access node generates a second update message in response to the first message. The second message includes a mobile node identifier and, in some embodiments is directed to the mobile node. The second message is received by a tracking agent, which updates location information corresponding to the mobile node. In the case where second message is an IP message and is routed to the mobile node using Mobile IP, a Mobile IP home agent routes the second message to the mobile node's last point of network attachment where the tracking agent is located and intercepts the message. The tracking agent may send a response message to the access node sending the second message.
摘要翻译：描述位置更新技术。休眠移动节点通过无线链路向接入节点发送第一消息来更新其位置信息。接入节点响应于第一消息生成第二更新消息。第二消息包括移动节点标识符，并且在一些实施例中指向移动节点。第二消息由跟踪代理接收，跟踪代理更新对应于移动节点的位置信息。在第二消息是IP消息并且使用移动IP路由到移动节点的情况下，移动IP归属代理将第二消息路由到移动节点的最后一个网络附着点，跟踪代理所在的位置并拦截该消息。跟踪代理可以向发送第二消息的接入节点发送响应消息。

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： Embodiments describe synchronizing access routers with wireless terminal state information. According to an embodiment is a wireless terminal that transmits a message that includes an address for at least two access routers. State change information can optionally be included in the message. According to another embodiment is an access router that receives a state change notification from a wireless device or another access router. The state change notification is updated in the access router. An acknowledgment confirming the updated state change may be sent to the wireless terminal. Dynamic state synchronization is provided with minimal communication with wireless terminal.
