    Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a first device. The first device operates a ROHC compressor in a first state at a ROHC sublayer to compress a first packet to be transmitted to a second device. The first packet includes information for a ROHC decompressor to establish a ROHC context. The information enables the ROHC decompressor to decompress a second packet compressed by the ROHC compressor when operating in a second state. The first device determines, at a sublayer or a layer lower than the ROHC sublayer, whether the first packet has been successfully received at the second device. The first device continues operating the ROHC compressor in the first state in response to a determination that the first packet has not been successfully received at the second device.

    Abstract: Disclosed are methods and apparatus for reducing a call setup time in wireless communication systems, particularly for systems employing SVLTE where an LTE network is used for data and a 1×CDMA network for voice. The methods and apparatus feature the capability during mobile terminated (MT) calls to modify a normal mode of operation of a predefined operation in a mobile terminal (e.g., call switched fallback (CSFB)), wherein processes normally performed for between a first network (e.g., LTE) are not performed in the mobile terminal, allowing a page response message to be sent directly, and thus sooner, to the other network (e.g., 1×CDMA) in response to an MT call page. This hybrid operation allowing the skipping of normal processes reduces the time for call set up.

    Abstract translation: 公开了用于减少无线通信系统中的呼叫建立时间的方法和装置，特别是对于使用LTE网络用于数据的SVLTE的系统和用于语音的1×CDMA网络的方法和装置。 所述方法和装置具有在移动终止（MT）呼叫期间修改移动终端中预定义操作的正常操作模式（例如，呼叫切换回退（CSFB））的能力，其中通常在第一网络 例如LTE）不能在移动终端中执行，从而允许响应于MT呼叫页面将页面响应消息直接发送到另一个网络（例如，1×CDMA）。 这种允许跳过正常进程的混合操作减少了呼叫建立的时间。
