摘要： A SIP header reduction protocol operating on a communication network to compress the SIP header fields on SIP control messages used to initiate a SIP communication session. The new protocol is implemented on the mobile use equipment (UE) (301) and P-CSCF proxy SIP server (302). The prior SIGCOMP compression dictionary is used to compress those header field parameters defined by the SIGCOMP dictionary. A new 3G Dictionary is implemented with header field parameters for several wireless specific data elements and parameters necessary to access various wireless technologies and services which are missing from the SIP/SDP based SIGCOMP dictionary. Finally, an Encoding Assistant (EA) (310, 355) function is implemented on the UE and P-CSCF that operates a standard encoding and decoding of SIP message header fields to reduce those SIP header fields that are dynamic over time but are essentially static in terms of most user communication. The EA parameters can be updated periodically, while the 3G and SIGCOMP dictionary are static and not updated.

摘要： Various embodiments are described to assist in reducing handoff delays and the blackout period(s) associated with inter AN (access network) hard handoffs. The hard handoff procedure of method disclosed herein establishes or initiates a connection (A10-type connection) between a target AN and a packet data serving node (PDSN), unlike known hard handoff approaches that wait until traffic channel assignment to establish or initiate such connection. The PDSN may optionally bicast data packets to both the source and target ANs since each is communicatively coupled to the PDSN during a given time period. In the event bicasting is unavailable or unused, a communication tunnel between the source and target ANs may be created and used to transmit data packets between them.

摘要： The invention consists of an authentication protocol for the Home Agent to authenticate and authorize the Mobile Node's Binding Update message. Two new mobility options compatible with RADIUS AAA are used to exchange a shared secret between the Home Agent and the Mobile Node so the Mobile Node can be authenticated. A Mobile Node-AAA authenticator option is added to the Binding Update message. The Home Agent generates the Mobile Node-AAA authenticator as a shared secret that it communicates as authentication data to the RADIUS AAA server on the home network. The RADIUS AAA server authenticates the communication and generates an Access-Accept message with a Mobile Node-Home Agent authenticator option. After receipt at the Home Agent, a Binding Update message with the Mobile Node-Home Agent authenticator option is transmitted from the Home Agent to the Mobile Node to use as an authenticator.

摘要： An improved wireless mobile IP system including an apparatus and method for managing transmission of information. Agent advertisements are used to detect movement of the mobile node and derive care-of addressing information for the Home Agent. Foreign Agents and Home Agents currently periodically broadcast an agent advertisement on the data channel. The claimed system reduces the need for agent advertisements by detecting movement of a mobile user into a new network using either the mobile node or a routine on a low-level protocol layer. After detection of movement, an agent solicitation message is transmitted from the mobile node or from the cell-site transmitter. The mobility agent then transmits a single agent advertisement in response. Derived care-of addressing information will then be registered with the Home Agent to support “tunneling” of communications to the mobile node through the foreign network. Transmission of agent advertisements and associated non-data traffic on the data channels will be reduced.
摘要翻译：一种改进的无线移动IP系统，包括用于管理信息传输的装置和方法。代理广告用于检测移动节点的移动并导出归属代理的转交寻址信息。外国代理和家庭代理商目前在数据频道上定期广播代理广告。所要求保护的系统通过使用移动节点或低级协议层上的例程来检测移动用户进入新网络的移动来减少代理广告的需要。在移动检测之后，从移动节点或小区现场发射机发送代理请求消息。移动代理然后响应地发送单个代理广告。然后将派生护理寻址信息注册到归属代理，以支持通过外部网络将通信“隧道化”到移动节点。数据通道上的代理广告和关联的非数据流量的传输将会减少。
