摘要： Control and status information between a mobile device and another device can be signaled over a voice channel using DTMF tones, e.g., a pre-defined sequence of DTMF tones can signal a desired message (more generally, a feature code). Tones sent are separated from each other by a time gap (T gap timer). If a receiving device does not receive a sequence of DTMF tones that can be matched to stored definitions of feature codes, then the receiving device generates a negative ACK. Also, if the sending device does not receive either negative or positive ACK, then sending device resends all tones of the feature code after a retry delay (T retry timer). Rather than having the T retry timer start when tones for a feature code start to be transmitted, the T retry timer is started after the T gap timer expires for the last tone of a feature code. Thus, only one timer is running (either T gap or T retry ), rather than having multiple timers running concurrently. Race conditions between the timers are avoided.
摘要翻译：移动设备与另一设备之间的控制和状态信息可以使用DTMF音调通过语音信道发信号通知，例如，预定义的DTMF音调序列可以发信号通知期望的消息（更一般地，特征码）。发送的音调通过时间间隔（T gap timer）彼此分离。如果接收设备没有接收到可以与存储的特征码的定义相匹配的DTMF音调序列，则接收设备产生否定的ACK。此外，如果发送设备没有接收到肯定ACK，则发送设备在重试延迟（T重试定时器）之后重新发送特征码的所有音调。而不是在特征码的音调开始发送的情况下开始T重试定时器，所以在特征码的最后一个音调的T间隔定时器期满之后，T重试定时器被启动。因此，只有一个定时器正在运行（T间隙或T重试），而不是同时运行多个定时器。避免计时器之间的竞争条件。

摘要： A system and method for handling stale messages is presented. A first message is transmitted to a peer entity. The first message includes a first timestamp. A second message is received from the peer entity. The second message is related to the first message and includes a second timestamp. A third message is received from the peer entity. The third message includes a third timestamp. A staleness of the third message is determined using the first timestamp, second timestamp, and third timestamp. When the third message is stale, the third message is at least one of ignored and discarded. When the third message is not stale, the third message may be processed.

摘要： An apparatus and method are described for resolving a glare condition between two SIP endpoints. The method allows a third party call control controller to resolve the glare condition when the ownership status of each dialog is the same, by initiating a back-off period of time at the apparatus based on the ownership status of the SIP dialog and re-sending a re-INVITE message to the end point after expiry of the back-off period of time.
