Abstract: A method for a wireless UE device to utilize tokens and cloud service technology to facilitate the provision of location data to an emergency call center. The UE may provide cellular signaling to initiate an outgoing telephone call to an emergency call center. A token may be provided during the signaling, wherein the token is associated with location information of the UE device stored on a server computer (referred to as a cloud server or location server). The token may uniquely identify the UE device and/or a user cloud service account of the UE device. The call center may use the token to retrieve location information of the UE from the cloud server. The use of the token may also provide for enhanced security, e.g., to prevent spoofing of the UE phone number.

Abstract: Method and apparatus for facilitating return to a first wireless network from a second wireless network by a wireless communication device is provided. A method includes the wireless communication device engaging in data transfer for an application session on the first wireless network; participating in a CSFB procedure to transition from the first wireless network to the second wireless network for servicing a voice connection; buffering data received for the application session before and/or during the CSFB procedure; releasing the voice connection; discontinuing requests for downlink data for the application session in response to termination of the voice connection to provide a gap in data transfer; reselecting to the first wireless network during the gap in data transfer; using the buffered data to continue the application session during reselection; and resuming data transfer for the application session on the first wireless network after completing reselection.

Abstract translation: 提供了一种用于通过无线通信设备从第二无线网络返回到第一无线网络的方法和装置。 一种方法包括：无线通信设备参与第一无线网络上的应用会话的数据传输; 参与CSFB过程以从第一无线网络转移到第二无线网络，用于维护语音连接; 在CSFB程序之前和/或期间缓冲为应用程序会话接收的数据; 释放语音连接; 响应于语音连接的终止而中断针对应用会话的下行链路数据的请求，以提供数据传输中的间隙; 在数据传输差距期间重新选择第一个无线网络; 在重新选择期间使用缓冲的数据继续应用会话; 并且在完成重新选择之后在第一无线网络上恢复用于应用会话的数据传输。
