摘要： Group communications methods and apparatus are described. Multicast operation is supported with the transmission characteristics, e.g., transmission power level, coding rate, and/or modulation method being selected to reliably communicate information to the end nodes in the group but not necessarily to all end nodes within the cell or sector. Thus resources can be conserved by matching transmission requirements with information on the requirements of one or more group members. The requirements for reliably reaching the end node with the worst channel conditions can, and in some embodiments is, used to determine the group transmission requirements. Power level and other transmission resource allocations can change in response to changes in group membership and/or conditions corresponding to existing group members.
摘要翻译：描述组通信方法和装置。支持多播操作，例如，被选择的传输功率电平，编码速率和/或调制方法可靠地将信息传送到组中的端节点，但不一定要传送到小区或扇区内的所有端节点。因此，可以通过将传输要求与一个或多个组成员的要求的信息相匹配来节约资源。可靠地到达具有最差信道条件的端节点的要求可以并且在一些实施例中用于确定组传输要求。功率等级和其他传输资源分配可以根据与现有组成员相对应的组成员资格和/或条件的变化而改变。

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： Group communications methods and apparatus are described. Multiple modes of group communications signaling are supported. In a first mode, copies of packets are separately transmitted to each group member in a sector or cell. In a second mode a copy of a packet is directed to multiple group members at the same time. Transitions between the two modes may be determined as a function of the cost of operating in each of the modes in terms of system cost and/or the number of group members in a cell or sector being serviced by a transmitter.

摘要： Improved group communications methods which are well suited for a wireless environment are described. End nodes request that access nodes make changes in group membership information maintained at the access node. The access node responds to the requests by a response signal indicating a grant or denial of the request. Requests may be to add or remove the end node, e.g., a mobile wireless terminal, from a particular group membership list identified in the request signal. The access node maintains a detailed list of group members and uses the information to control how signals, e.g., packets, are transmitted to the group members. Group membership information may be updated at the node at the time of handoff and/or an end node enters the cell or otherwise changes its point of network attachment.

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.
