摘要： A home agent (104, 108) and a foreign agent (110, 114) in a wireless communication system (100) establish (202) a special communications channel (140-154) between themselves, the special communications channel dedicated to messages addressed to multiple mobile nodes. The home agent then detects (206) whether a message received by the home agent is addressed to multiple mobile nodes. When the message is addressed to multiple mobile nodes, the home agent sends (208) the message to the foreign agent through the special communications channel.

摘要： A communication device minimizes an opportunity for a queue stall during a communication session employing a reliable transport protocol by setting a current mode of operation for a Radio Link Protocol (RLP) and, based on a quality of an air interface, switching to an RLP mode of operation different from the current mode during the communication session.

摘要： A method and system for fast IP handoff of a mobile node (MN) (102) from a first wireless network (106) to a second wireless network (108) is disclosed. The method includes releasing (402) a tunnel between a first access router (AR) (204) and a second FA (206), based on at least one predefined criterion. The method also includes initializing (404) a mobile IP registration procedure with the second FA. The mobile registration procedure is performed by the MN.

摘要： Various embodiments are described to address the need for an apparatus and method that improves link layer handoff by addressing the packet-loss problem existing today. An intermediate buffer management layer (IBML) (201, 211) is introduced below layer 3 of an OSI-based communications interface. The IBML buffers copies of OSI layer 3 packets being transmitted via lower layers (205, 215) of the interface and manages the buffer contents using indications the IBML receives from one or more of the lower layers. When the IBML receives an indication that a link layer hard handoff is proceeding, the IBML transfers the presently buffered packets to a corresponding IBML (202, 212) in the target communications interface. This sub-layer 3 buffer transfer enables the target communications interface to reduce packet-loss associated with the hard handoff.
摘要翻译：描述了各种实施例以解决对通过解决目前存在的分组丢失问题来改进链路层切换的装置和方法的需求。在基于OSI的通信接口的层3之下引入中间缓冲器管理层（IBAM）（201,211）。 IBML缓冲器通过接口的较低层（205,215）发送的OSI层3数据包的副本，并使用IBML从一个或多个较低层接收的指示来管理缓冲器内容。当IBML接收到链路层硬切换正在进行的指示时，IBML将当前缓存的分组传送到目标通信接口中的相应IBML（202,212）。该子层3缓冲器传送使得目标通信接口能够减少与硬切换相关联的分组丢失。

摘要： A method of performing a modified RLP that reduces the transmission delay in a communications system by detecting frame erasures when they occur. The modified RLP method requests retransmission of erased frames based on pattern violations instead of sequence number violations. The method is preconditioned to expect a particular repeating pattern of frame delivery. For a system running a VSELP vocoder, the method in a receiving device expects to receive full rate or data (F) and DTX (D) frames in a repeating pattern FFDFFDFFD. For a system running an AMBE vocoder, the method in a receiving device expects to receive frames in a repeating pattern DFDFDFDD. The method detects when the pattern is violated and in desired instances immediately requests retransmission of the expected frame.

摘要： A method (1700) and apparatus (1801) provide channel estimation with extended bandwidth filters. Antenna (1813) receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (320). One of a plurality of filters (603, 605, 607, and 609) including extended bandwidth filters (311) and a default filter (305) can be selected by a selector (617). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.
