    摘要: Third party call control in a service management platform (SMP) of an enterprise system comprising a private branch exchange (PBX) in communication with the SMP over a trunk and line. Receiving a request over the line for communication involving a device. Invoking reliable transmission of provisional responses in the trunk. Receiving a receive only session description over the trunk. Invoking specific event notification between the SMP and PBX for calls answered between the device and PBX. Receiving notification of a call answered between the device and PBX. Responding to the request with the first session description as a send/receive offer. Receiving acknowledgement including a second send/receive answer session description over the line. Updating the trunk the second description as a send/receive update. Receiving a third session description with a successful response message from the PBX; the third session description being a send and receive copy of the first session description.

    摘要: Mobile devices use a PBX and application servers associated with the PBX to access voice services. Some mobile devices can support simultaneous data and voice channels, with the PBX and application server respectively. Where a data channel is unavailable, a control and status updating mechanism is needed. One approach is to signal over the voice channel with DTMF tones. DTMF tones should be timed to cause the tones to arrive at the mobile device during a pause period of a ring cycle. However, it also is desirable to avoid unnaturally long silence periods or other pauses during system usage. Aspects relate to enhancing a user experience in these situations and successful transmission/reception of control and status information over a voice channel using DTMF tones.

    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 (Tgap 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 (Tretry timer). Rather than having the Tretry timer start when tones for a feature code start to be transmitted, the Tretry timer is started after the Tgap timer expires for the last tone of a feature code. Thus, only one timer is running (either Tgap or Tretry), rather than having multiple timers running concurrently. Race conditions between the timers are avoided.
