    • Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for opportunistically transitioning service flows of mobile devices between being direct and indirect. In various embodiments, a proximity between first and second mobile devices that are in wireless communication with each other may be monitored. In various embodiments, a selective transition of a service flow between the first and second mobile devices from being indirect through the radio network access node using a first radio access technology (“RAT”) to being direct using a second RAT may be facilitated, e.g., responsive to a determination that a first criterion has been met. In various embodiments, a selective transition of the service flow from being direct using the second RAT to being indirect using the first RAT may be facilitated, e.g., responsive to a determination that a second criterion has been met.
    • 本文描述了计算机实现的方法,系统,计算设备和计算机可读介质的实施例,用于在直接和间接之间机会地转换移动设备的服务流。 在各种实施例中,可以监视彼此无线通信的第一和第二移动设备之间的接近度。 在各种实施例中,可以方便地将第一和第二移动设备之间的服务流的选择性转换通过使用第一无线电接入技术(“RAT”)的无线电网络接入节点间接地直接使用第二RAT,例如 响应于已经满足第一标准的确定。 在各种实施例中,可以方便地例如响应于已经满足第二标准的确定来促进服务流从直接使用第二RAT到间接使用第一RAT的选择性转换。
