    • The disclosure relates to techniques for maintaining minimum quality of service (QoS) communication sessions with a wireless communication device (WCD) over a data-based communication network during a hard handoff between access networks for the WCD. More specifically, the techniques determine whether a closed connection between the WCD and a first access network during a minimum QoS communication session is due to a hard handoff between the first access network and a second access network. In the case of a hard handoff, the techniques maintain open QoS reservations associated with data flows included in the minimum QoS communication session for a predetermined period of time to enable a new connection to be established between the WCD and a second access network. The techniques described herein may especially useful when performing a voice over Internet Protocol (VoIP) call over an Evolution-Data Optimized (EVDO) communication network.
    • 本公开涉及在用于WCD的接入网络之间的硬切换期间通过基于数据的通信网络来维持与无线通信设备(WCD)的最小服务质量(QoS)通信会话的技术。 更具体地,该技术确定在最小QoS​​通信会话期间WCD和第一接入网络之间的闭合连接是否是由于第一接入网络和第二接入网络之间的硬切换。 在硬切换的情况下,技术保持与包括在最小QoS​​通信会话中的数据流相关联的预定时间段的开放QoS保留,以使得能够在WCD和第二接入网络之间建立新连接。 当在演进数据优化(EVDO)通信网络上执行通过因特网协议(VoIP)呼叫的语音呼叫时,本文描述的技术尤其有用。
