    • Systems, methodologies, and devices are described that facilitate transferring a subset of compression context from a source base station to a target base station during an inter-base station handover of a mobile device to facilitate establishment of compression context between the mobile device and target base station. The source base station can transfer a subset of compression context comprising static and semi-static context to the target base station during inter-base station handover to at least partially establish compression context between the mobile device and target base station prior to or during handover. The source base station can transmit, to the mobile device, indicator information related to compression context transferred. The target base station can at least partially establish compression context based on received subset of compression context to facilitate efficient communication with the mobile device and can establish any remaining portion of compression context with the mobile device after handover.
    • 描述了在移动设备的基站间切换期间促进将压缩上下文的子集从源基站传送到目标基站的系统,方法和设备,以便于在移动设备和目标基站之间建立压缩上下文 站。 源基站可以在基站间切换期间将包括静态和半静态上下文的压缩上下文的子集传送到目标基站,以在切换之前或期间至少部分地建立移动设备与目标基站之间的压缩上下文。 源基站可以向移动设备发送与传送的压缩上下文相关的指示符信息。 目标基站可以基于所接收的压缩上下文的子集来至少部分地建立压缩上下文,以促进与移动设备的有效通信,并且可以在切换之后与移动设备建立压缩上下文的任何剩余部分。

    • Techniques for supporting handoff of terminals between a packet-switched network and a circuit-switched network are described. In an aspect, handoff between packet-switched and circuit-switched networks may be facilitated by a designated network entity in the packet-switched network. The designated network entity may interface with both the packet-switched network and the circuit-switched network, perform circuit-switched call origination, and perform handoff procedure. In one design, a first terminal may communicate with the packet-switched network for a packet-switched call with a second terminal. The first terminal may initiate handoff to the circuit-switched network via the designated network entity. The first terminal may perform handoff from the packet-switched network to the circuit-switched network based on an inter-MSC handoff procedure. The first terminal may then communicate with the circuit-switched network for the circuit-switched call with the second terminal after the handoff.
    • 描述了用于支持分组交换网络和电路交换网络之间的终端切换的技术。 在一方面,分组交换网络中的指定网络实体可以方便分组交换网络和电路交换网络之间的切换。 指定网络实体可以与分组交换网络和电路交换网络接口,执行电路交换呼叫发起,并执行切换过程。 在一种设计中,第一终端可以与分组交换网络进行通信,以便与第二终端进行分组交换呼叫。 第一终端可以通过指定的网络实体发起切换到电路交换网络。 第一终端可以基于MSC间切换过程执行从分组交换网络到电路交换网络的切换。 然后,第一终端可以在切换之后与第二终端与电路交换网络进行电路交换呼叫的通信。
