摘要： A system for handing off a mobile node includes a mobile node and a target foreign agent. To effectuate a handoff of the mobile node from an anchor foreign agent to the target foreign agent, a tunnel can be established therebetween such that data packet(s) sent between the mobile node and a correspondent node pass between the target foreign agent and the anchor foreign agent through the tunnel. After the tunnel is established, the mobile node can register with the target foreign agent to thereby bind the mobile node to the target foreign agent such that data packet(s) sent between the mobile node and the correspondent node pass through the target foreign agent to the correspondent node independent of the anchor foreign agent and the tunnel. Thereafter, the target foreign agent can close the tunnel between the target foreign agent and the anchor foreign agent.

摘要： In an exemplary embodiment of this invention contexts are transferred at an appropriate time depending on the context type. As a result, link layer (PPP) delay can be substantially eliminated during Mobile IP handoff, without introducing additional packet loss. By way of example, all MS contexts (both static and dynamic) are maintained during the inter-PDSN handoff procedure, and any executing applications are not impacted by the inter-PDSN handoff.
摘要翻译：在本发明的示例性实施例中，上下文根据上下文类型在适当的时间被传送。因此，在移动IP切换期间，可以基本上消除链路层（PPP）延迟，而不引入额外的分组丢失。作为示例，在PDSN切换过程期间维护所有MS上下文（静态和动态），并且任何执行的应用不受PDSN间切换的影响。

摘要： Disclosed is a method and apparatus to provide an IP connection between a mobile station (MS 10) and a computing device (CD 12). The method includes initiating the set up of the IP connection with a command sent from the CD to the MS over a local interface (13) and, in response to receiving over the local interface an IP message at the MS from the CD, routing the received IP message to an application that is resident in the MS. 2. In a presently preferred first embodiment the command is an AT command, more specifically an AT+CRM command having a value of five. In a presently preferred second embodiment the command places the MS into an auto-answer mode, and is an ATSO=1 command.

摘要： In exemplary embodiments of this invention context transfers (static and dynamic) are optimally performed to maintain the same quality of service (QoS) for a Mobile Station (MS) during a CDMA inter-BS hard handoff, as well as during a CDMA inter-BS soft handoff. Context transfers (static and dynamic) are also optimally performed to maintain the same QoS for the MS during a CDMA inter-Packet Control Function (PCF) hard handoff.
