To surely prevent a normal mode from being restored from an energy saving mode by off-hook.SOLUTION: The ringer interrupt control unit 44 outputs the ringer interrupt signal S2 according to the ringer detection signal S1 when the off-hook detection signal S3 is not output (that is, in a state where the receiver of the external telephone 37 is put down), so that the mode control unit maintains the energy saving mode and does not switch to the normal mode even when the receiver of the external telephone is lifted and the off-hook signal is output (that is, even when the off-hook detection signal is output) in the energy saving mode. As a result, the mode control unit does not switch from the energy saving mode to the normal mode only by lifting the receiver of the external telephone, thereby preventing a decrease in energy saving efficiency.SELECTED DRAWING: Figure 2

The embodiment of the invention provides a video polyphonic ringtone playing method and terminal equipment, and the method is executed by first terminal equipment, and comprises the steps: playing a video polyphonic ringtone signed by second terminal equipment in a process that the first terminal equipment initiates a voice call request to the second terminal equipment, and displaying a video polyphonic ringtone interface; before receiving the off-hook message of the second terminal equipment, the first terminal equipment does not receive a message which is sent by a core network and is used for indicating to close the video polyphonic ringtone; after an off-hook message of the second terminal device is received, if it is determined that a first condition is met, the first terminal device automatically switches a video polyphonic ringtone interface to a voice call interface, the first condition comprises that the current call type of the first terminal equipment is a voice call, but the current media capability is a video capability, and the video capability corresponds to a video polyphonic ringtone media capability. Therefore, the video polyphonic ringtone can be closed under the condition that the video polyphonic ringtone scene is abnormal, and the video polyphonic ringtone is normally switched to the voice communication interface, so that the user experience is improved.

The application discloses a multifunctional test system and method for a repeater. The system comprises: an analog telephone test module for simulating telephone off-hook, telephone on-hook or telephone access working conditions; a Type-C double-sided test module for simulating Type-C interface normal insertion or reverse insertion working conditions; a PD trigger module for outputting different grades of PD working voltage of the repeater to simulate fast charging working conditions; an analog load test module for simulating load working conditions; and a control module for controlling the analog telephone test module, the Type-C double-sided test module, the PD trigger module and the analog load test module to test the repeater respectively. The application reproduces the real working conditions of telephone off-hook, on-hook and access, combines the simulation of Type-C interface normal insertion and reverse insertion and the output of PD fast charging voltage, and controls multiple modules cooperatively, so as to fill the blank of the single function and high cost of the traditional test platform; the full-automatic closed-loop test improves the test efficiency, avoids the error of manual operation, and ensures the accuracy and reliability of test data.

The invention relates to a privacy number implementation method for playing a common ring-back tone when an ISBC is called out. The privacy number service platform replaces the real number of the user with the temporarily distributed privacy number to carry out communication, establishes a binding relationship between the privacy number and the calling and called users, and realizes a number privacy protection service; the privacy number service platform converts the privacy number according to the privacy number binding relation, hides real numbers of the calling terminal and the called terminal, and applies and distributes multimedia resources at the same time to complete multimedia format pre-negotiation; and when the private number service platform receives the called 200 OK response, indicating that the call is subjected to off-hook response, stopping playing the ring-back tone, and finally realizing the call between the calling user and the called user. The method is based on the standard SIP protocol and the BICC protocol, core network equipment of an operator does not need to be transformed, the method is simple and easy to implement and low in cost, normal conversation of a user is not affected, and the service experience of the user is improved.

The present application relates to the technical field of video ringback tone call method and system, and particularly relates to a video ringback tone call method and system, the method comprising: a calling party dials a called party who has signed a video ringback tone service, triggers a video ringback tone application, and plays a video ringback tone for the calling party by a video ringback tone platform; when the called party answers the call, the video ringback tone platform reinitiates media negotiation between the calling party and the called party; separates the audio media link and the video media link between the calling party and the called party; after the media negotiation is completed, the calling party and the called party start to call, and the audio media and the video media are respectively transmitted through their own links. In the video ringback tone platform, the application innovatively adopts the technology of separating the audio and video media transmission paths of the calling party and the called party, the stability of the audio and video call under poor network conditions is greatly enhanced, and the call experience of the user is greatly improved.
