A method of controlling a call between first and second user terminals, the method comprising: during the call, detecting a failure of a connection between the first user terminal and a packet-switched network; and in response, causing the call to be conducted at least part way via a PSTN network, via a connection between the first user terminal and the PSTN network. The call may be initiated by the first user terminal (such that the first user terminal is the caller and the second is the callee). The call may be initially conducted, prior to the failure, via a packet-switched connection between the first user terminal and a packet-switched network. The method may be implemented by a client application run on the first user terminal. Alternatively, the method may be implemented by a server.

Described herein are methods, devices, media, and systems for managing emergency communications and providing seamless data extraction from a communication device by an emergency service.

An integrated dialer (a software telephony application) with elastic calling features for mobile cellular devices. The integrated dialer would pass control of originating emergency service calls to the native dialer. It would automatically switch silently between wi-fi, PSTN, and cellular data services as needed depending on the quality of service (QoS) of the services. In addition, it would support the telephony services for multiple devices, each having the same telephone number.

A computer-implemented method for managing calls in a collaboration environment is provided. The method includes receiving, by a processor, a call into a collaboration session of the collaboration environment. The method also includes identifying, by the processor, a user from a plurality of users associated with the collaboration session, based on at least one of contextual information regarding the call and information regarding the plurality of users. The method further includes providing, by the processor, an interface on a device associated with the identified user, wherein the interface enables the identified user to instruct the device to handle the call within the collaboration session.

A method, an apparatus and a system for a handover to a circuit switched domain are disclosed. In an embodiment, a system includes a mobility management entity (MME) and at least two a mobile switching center (MSCs), wherein the at least two MSCs comprise a first MSC capable of supporting a circuit switched fallback (CSFB) and a single radio voice call continuity (SRVCC) and a second MSC not capable of supporting the SRVCC, and wherein the MME is configured to select the first MSC for a user equipment (UE) from the at least two MSCs in a combined tracking area update procedure of the UE when a location service of a circuit switched (CS) domain triggers an SRVCC procedure for the UE and when the UE has a Voice over Internet Protocol (VOIP) service in progress.

An apparatus and method of performing automated administrative operations on a mobile device. One example method may include determining via a hosted server that an action needs to be performed by a mobile device under management. The method may further include generating a message via the hosted server, the message includes the action, and transmitting the message to the mobile device under management, and receiving a result message from the mobile device under management responsive to the transmitted message, the result indicating that the action has been satisfied.

A method, apparatus and computer program product are provided to facilitate the handover from a packet switched network to a circuit switched network while an Internet protocol (IP) multimedia subsystem (IMS) session is ongoing. In the context of a method, a notification is received of the handover from a packet switched network to a circuit switched network while an IMS session is ongoing. The method also receives an indication that an emergency call service is active in the IMS session and determines that media resources in the circuit switched network are required to support the emergency call service, as supplemented by a minimum set of emergency related data, that is active in the IMS session. The method may further include causing the media resources to be reserved in the circuit switched network to support the emergency call service that is active in the IMS session.

Described herein are methods, devices, media, and systems for managing emergency communications and providing seamless data extraction from a communication device by an emergency service.

A system described herein improves user equipment (UE) access to call and data services provided by a network carrier by updating settings on the UE based device data from the UE. The updates may modify the UE hardware configuration, including activating or deactivating different network radios of the UE, enable or disable different call or data services accessed through the different network radios, and/or modify parameters controlling UE network selection and switching (e.g., handoff). In doing so, the system may improve the user experience when accessing wireless services of the network carrier and resolve quality issues whether due to poor signal strength, congested networks, or excessive network switching.

Measures are provided for use in establishing a telephony session between first and second telephony devices in a telephony network. Telephony network equipment in the telephony network receives, from the first telephony device over a signalling link, a telephony session establishment request. The telephony network equipment receives, from the first telephony device over a data link that is separate to the signalling link, a message comprising data useable by the telephony network equipment to identify the second telephony device. The telephony network equipment correlates the received telephony session establishment request and the received message. The telephony network equipment transmits, to the second telephony device, a telephony session establishment request on the basis of the correlating. The first telephony device is associated with a multi-persona user having a first persona associated with a first telephony identifier and a second persona associated with a second telephony identifier.
