A call switching method and apparatus, a storage medium and a mobile terminal. The method comprises: when a first call module receives a call request of a first call type, triggering a second call module to query whether a call of a second call type is being executed; if a call of the second call type is currently being executed, the first call module generating prompt information; and when a first user instruction of a user is detected, switching the current call from the call of the second call type to a call of the first call type.

Providing a voice call includes: receiving, from a user equipment (UE), a request to initiate a voice call traffic session; requesting setup of a voice call data pipe; based on at least a setup of the voice call data pipe not completing prior to a timer event, transmitting voice packets over a signaling data pipe; and based on at least the voice call data pipe setup completing, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe. Placing a voice call includes: requesting, by the UE, to initiate the voice call traffic session; based on at least a first trigger event, transmitting voice packets over the signaling data pipe; and based on at least a second trigger event, ceasing to transmit voice packets over the signaling data pipe and transmitting voice packets over the voice call data pipe.

Present invention refers to a method and a system for intelligent routing of an incoming call over a dual telecommunication network supporting both CS and PS connections, comprising: initiating, from a call router server, a CS call establishment connection; at roughly the same time, sending, a push message over the PS connection to a callee's mobile device; as result of receiving the push message, registering said callee's mobile device into the call router server; providing the call router server with a measure of quality of a PS connection; and in the event of receiving, at the call router server, an unreachable notification from the CS connection and the measure of quality is higher than a pre-established minimum value, routing the incoming call through the PS connection.

Systems and methods for communications are disclosed. The systems and methods can monitor a cloud-based voice over internet protocol (VoIP) calling system to determine an active call. The systems and methods can also analyze the active call to determine an indication of call quality, the analyzing occurring during the active call. Additionally, the systems and methods can compare the indication of call quality to a quality threshold. The compare can occur during the active call to determine when the active call has a poor call quality. The systems and methods can also report the poor call quality based on the comparing the indication of call quality to the quality threshold.

A central routing function (CRF) platform. The CRF platform comprises a processor, a memory that stores prioritized call route lists, and an application stored in the memory. When executed by the processor the application receives a request for a prioritized call route list from a network element, where the request comprises an indication of a location of a call originator of a call and a destination telephone number, determines a call type of the call, selects a prioritized call route list associated with the destination telephone number from the non-transitory memory based on the call type, determines that a percent allocation rule applies to the call, based on the percent allocation rule, removes the first priority call route from the selected prioritized call route list to make an adapted prioritized call route list, and sends the adapted prioritized call route list to the network element.

An example operation may include one or more of receiving, via a telephone network, a Voice over IP (VOIP) call from a network device, detecting a disturbance value from a tag that has been added to a VOIP message of the VOIP call, determining an answer priority of the VOIP call based on the disturbance value, and processing the VOIP call based on the determined answer priority.

A conference call management method, system, and computer program product include inferring an Internet Protocol (IP) address of a new user requesting to join a call including at least one other user, inferring a codec to stream an emulated network pattern for the call if the new user were to join the call, measuring a call quality perceived by the at least one other user in the call while the emulated codec is run on the call, and measuring an impact on the call quality in a case that the new user joins the call based on the perceived call quality and the network pattern.
