The present disclosure provides a system and a method for voice prompt of a third-party call. The system includes a contact identification module, a hands-free control module and a voice broadcast module. The contact identification module is for identifying whether a third-party incoming call number exists in an address book of a communication device. The hands-free control module is for extracting a current call status when a third-party call dials in to help judge whether the current call is in hands-free mode. The voice broadcast module is for voice broadcasting information of the incoming call according to the identification result of the contact identification module when the current call is in hands-free mode. The present system could broadcast the information of the third-party incoming call without breaking off the current call so that prevents missing important content of the current call as well as an important incoming call.

Described are call handling methods performed by a carrier network or client stations. A method performed by a carrier network includes designating rules for call handling for an account, receiving first and second voice calls for the account, wherein the voice calls may be either an incoming calls or originated calls and handling the first and second voice calls for the account based on the rules. A method performed by a client station includes receiving a first invitation to a first call, responding to the first invitation causing the first call to be active, receiving a second invitation to a second call while the first call remains active and responding to the second invitation causing the second call to be active and the first call to be on hold, the client station is prevented from originating a call when one call is active and one call is on hold.

A communication device controlling method, for controlling a communication device including a first subscriber identification and a second subscriber identification when a process of a data call established with the first subscriber identification is in a suspension, comprising: (a) receiving, by a processor of the communication device, a request to establish a mobile terminated (MT) call with the second subscriber identification; and (b) resuming, by the processor, the process of the data call from the suspension before an instruction of accepting or rejecting the request is received if the MT call is packet-switch based.

A method for transferring control of an existing multi-participant conversation in which at least two communication terminals are connected to each other through a data connection to a conference control application can include the following steps: establishment of a virtual conference room that serves as an anchor point for the application and can be a virtual participant in the conference, switching of the conference room into the existing data connection and assignment of the master role to the conference room. A signal generated by the application can cause the switching of the conference room into the existing data connection and the assignment of the master role to the conference room.

Systems and methods for improved e911 call handling. The system enables users to create multiple categories of callers. When a user makes a 911 (emergency) call, different categories of users receive different treatment. A call from a public safety access point (PSAP), for example, can be routed to the user's user equipment (UE). A caller on a favorites list may also receive the same, or similar, treatment. General callers, on the other hand, can be sent directly to voicemail, as is currently the practice for all callers. The system can enable certain callers to be sent to the UE to activate call-waiting, even though the user is on an emergency call, rather than being sent to voicemail with no explanation. The system can be used to provide this service to family members, healthcare professionals, PSAPs, and other important callers.

Systems and methods for optimized call handling during e911 calls. Normally, when a user equipment (UE) is connected to a public safety answering point (PSAP)e.g., is on a 911 callall incoming calls are automatically routed to voicemail. In contrast, the systems and methods disclosed herein enable calls that were dialed within a predetermined time window of the 911 call to be sent through to call-waiting to enable the user to accept or reject the call. The system can use a guard timer to determine whether a call is within the predetermined time window. The system can include a single guard timer for all incoming callse.g., any call made from the UE within the previous X minutes prior to the 911 call. The system can also include individual guard timers for each call that expire separately relative to the call's proximity to the 911 call.

A method for controlling a mobile communications device and a mobile communications device including a radio processing circuit and a baseband processing circuit adapted to interact with the radio processing circuit, configured to: receive a first call on a first subscriber identity module of a mobile communications device; receive a second call on a second subscriber identity module of the mobile communications device; suspend the first call on a local hold; switch to the second call from the first call; transmit a message to the first call while the second call is active.

A call processing method, including receiving a first call request of a calling terminal for a called terminal, triggering a mobility management entity to control a base station to page the called terminal, performing call waiting according to a paging response message when receiving the paging response message from the mobility management entity indicating that the called terminal is a power saving state and cannot be paged by the base station, and establishing a session coupling between the calling terminal and the called terminal according to addressing information of the called terminal when receiving, in a call waiting process, the addressing information of the called terminal from the mobility management entity.

Embodiments herein provide a method and system of responding to a call with a text. The method includes receiving by a target communication device a call from an initiator communication device. The target communication device responds to the from call with a real time text (RTT). One or more characters in the RTT are sent instantaneously to the initiator communication device.
