    • Devices that are enabled to communicate with each other, via an ad hoc conference mode and an infrastructure supported conference mode, can evaluate one or more resources required to support an ad hoc conference communication session and/or one or more quality metrics associated with the ad hoc conference communication session, and determine whether one or more resources or metrics are outside optimal operating parameters. If so, the device can initiate a transition from the ad hoc conference communication session to an infrastructure supported conference communication session hosted at a conference server. This way, the devices can drop the ad hoc conference communication session when one or more of the resources or metrics are outside optimal operating parameters, so that one of the devices does not need to mix communication information streams (CISs) from the devices, generate a plurality of conferenced communication information streams (CCISs), and transmit a unique one of the conferenced communication information streams (CCISs) to the other devices.
    • 能够通过特别会议模式和支持基础设施的会议模式相互通信的设备可以评估支持特设会议通信会话所需的一个或多个资源和/或与广告相关联的一个或多个质量度量 并且确定一个或多个资源或度量是否在最佳操作参数之外。 如果是这样,则设备可以启动从特设会议通信会话到在会议服务器上托管的基础架构支持的会议通信会话的转换。 这样,当一个或多个资源或指标在最佳操作参数之外时,设备可以丢弃自组织会议通信会话,使得设备中的一个不需要混合来自设备的通信信息流(CIS),产生 多个会议通信信息流(CCIS),并且将另一个会议通信信息流(CCIS)中的唯一一个发送到其他设备。

    • Disclosed is a method that includes initiating a handoff (403) by transmitting a handoff (403) start message to a mobility manager by a first mobile station. The first mobile station is in a call with a second mobile station and moving out from a first communication network to a second communication network. The handoff start message comprises a first call context. The first communication network comprises various network entities such as a SIP server, mobility manager, and the like. The method further includes creating a SIP instance (404) in the mobility manager to hold the first call context. Further, a handoff extension call is placed (405) by the first mobile station to the SIP server via the second communication network and once the handoff extension call is placed, an INVITE message is sent (406) from the SIP server to a preconfigured extension of the mobility manager. The INVITE message comprises a second call context. Thereafter, the handoff extension call is redirected (409) from the second communication network to the first communication network via the mobility manager, in response to the INVITE message received by the preconfigured extension of the mobility manager.
    • 公开了一种方法,其包括通过由第一移动台向移动性管理器发送切换(403)开始消息来发起切换(403)。 第一移动站与第二移动站进行通话,并从第一通信网络移出到第二通信网络。 切换开始消息包括第一呼叫上下文。 第一通信网络包括诸如SIP服务器,移动性管理器等的各种网络实体。 该方法还包括在移动性管理器中创建SIP实例(404)以保持第一呼叫上下文。 此外,由第一移动站经由第二通信网络将切换分机呼叫(405)发送给SIP服务器,并且一旦设置了切换分机呼叫,则从SIP服务器向预配置的分​​机(406)发送INVITE消息(406) 的流动经理。 INVITE消息包括第二呼叫上下文。 此后,响应于由移动性管理器的预先配置的扩展接收到的INVITE消息,通过移动性管理器将切换分机呼叫从第二通信网络重定向到第一通信网络(409)。
