    • Methods and apparatus for enhancing Mobile IP (MIP) signalling and to support the use of a novel proxy Co-located Care-of Address (PCCoA) are described. The enhanced MIP signalling adds the ability for the Mobile Node (MN) (504) to acquire a MN specific Foreign Agent (FA) (505) CoA that provides the MN (504) with a topologically correct local address yet whose tunnel encapsulation/decapsulation is provided by the FA (505). This address is called a proxy CCoA (PCCoA) (2116) and the associated processing in the MN (504) and FA (505) is called Proxy CCoA tunneling. This capability is applicable to any access technology but is especially useful for wireless systems where the access bandwidth is expensive and when point-to-point link-layer connectivity exists between the MN (504) and the FA (505). A method is supported for reverse tunneling and smooth hand-off extensions based on the PCCoA that enables inter-FA forwarding even for CCoAs.
    • 描述了用于增强移动IP(MIP)信令和支持使用新颖的代理协同地址转交地址(PCCoA)的方法和装置。 增强的MIP信令增加了移动节点(MN)(504)获取为MN(504)提供拓扑正确的本地地址但具有隧道封装/解封装的MN特定外部代理(FA)(505)CoA的能力 由FA(505)提供。 该地址被称为代理CCoA(PCCoA)(2116),并且MN(504)和FA(505)中的关联处理被称为代理CCoA隧道。 该功能适用​​于任何接入技术,但对于接入带宽昂贵的无线系统以及当MN(504)和FA(505)之间存在点对点链路层连通性时尤其有用。 支持基于PCCoA的反向隧道和平滑切换扩展的方法,即使对于CCoA也能够进行FA间转发。

    • This application describes how Session Description Protocol (SDP) preconditions signaling can be enhanced to support lead role negotiation, precondition capability exchange, premature precondition attempts, and concatenated preconditions processing. The application describes the use of send and receive tags (1004) in an SDP message (1012) for a given media line. In a given message, a success or failure tag (1018) may be associated with a send or receive tag in addition to an optional or mandatory condition indicator tag. A lead role indicator may also be associated with a send or receive tag to indicate a desired preference with regard to the sender or receiver taking the lead role. These additions lead to a greater chance of successful session set-up completion, reduce the number of signaling exchanges in general, and enable precondition attempts to be started earlier and to be executed in parallel.
    • 本应用程序描述了如何增强会话描述协议(SDP)前提条件信令,以支持前导角色协商,前提条件能力交换,过早前提条件尝试以及级联前提条件处理。 该应用描述了在给定媒体线路的SDP消息(1012)中使用发送和接收标签(1004)。 在给定消息中,成功或失败标签(1018)可以与发送或接收标签相关联,除了可选或强制性条件指示标签之外。 主要角色指示符也可以与发送或接收标签相关联,以指示关于发起者或接收者担任主角的期望偏好。 这些增加导致成功的会话建立完成的机会更大,减少了一般信令交换的数量,并且使前提条件尝试更早地启动并并行执行。
