A communication device may include a message generator configured to generate a message in accordance with a command set to use a communication service provided by a communication session setup protocol; and a modem circuit coupled to the message generator and configured to operate in accordance with the message generated by the message generator; wherein the message generator is configured to generate the message comprising a command to at least one of control or establish an Internet Protocol Multimedia Subsystem service.

Communication devices and methods for operating a communication device

A method and a subscriber station for allocating rights of access to a telecommunications channel of the telecommunications network to at least one subscriber station () are proposed in which information signals are transmitted to the at least one subscriber station (). With the information signals, access authorization data () are transmitted to the at least one subscriber station (). Upon reception of the access authorization data () in an evaluation unit () of the at least one subscriber station (), the question is asked whether the access authorization data () include an access threshold value (S), and the access threshold value (S) is compared with a random number or a pseudo-random number (R), and the right of access to a telecommunications channel of the at least one subscriber station () is granted as a function of the outcome of comparison.

Technology for initiating emergency calls is disclosed. A minimum set of emergency related data (MSD) associated with the emergency call may be identified at a terminal equipment (TE) of a mobile terminal. An attention (AT) command may be generated that includes the MSD and selected configuration information related to the emergency call. The AT command may be sent from the TE of the mobile terminal to a mobile termination (MT) of the mobile terminal in order to setup the emergency call, wherein the mobile terminal (MT) routes the emergency call to a public safety answering point (PSAP) in a communication network.

Emergency call handling

For transmitting messages in a radiotelecommunications network from a first subscriber station, a transmission frame at least two data fields with data in a first data format transmitted in a first data field of the short message, and data in a second data format, different from the first data format, are transmitted in a second data field of the short message, a first identification code, which identifies a makeup of the short message, is transmitted in the first data field and includes information about at least one of a number of data fields, one or more data formats of data in the data fields, and a size of the data fields, and in each of two data fields, one data-field-specific identification code, which identifies a makeup and content of the corresponding data field, per data field is transmitted.

In a method for determining active communication sessions, a request to determine active communication sessions is received. Queries as to whether communication sessions are currently active are sent to at least two communication session servers. The respective query answers that indicate one or more active communication sessions being controlled by the respective communication server are received. A first answer that indicates one or more active communication sessions being controlled by the at least two respective communication servers is sent. A communication session information server executes the method.

Embodiments of a mobile device, a User Equipment (UE), and method for supporting emergency calls on a packet-switched network are generally described herein. In some embodiments, the UE may be configured to support emergency calls in accordance with a 3GPP protocol and with eCall in an IP Multimedia Subsystem (IMS) session. The UE may comprise hardware processing circuitry configured to transmit traffic packets to an Evolved Node-B (eNB) for forwarding to a receiving station, which may be a Public Safety Answer Point (PSAP). In some embodiments, the transmission of traffic packets during a packetization period may be restricted to one of transmission of voice packets or transmission of data packets. In some embodiments, at least some of the data packets may include Minimum Set of Emergency Related Data (MSD), and the IMS session may be configured in accordance with Real Time Transport Protocol (RTP).

In a method for requesting media replication in a collaborative communication session, a message is sent which specifies that a communication medium for a collaborative communication session, which is currently being transmitted to at least one terminal, should additionally be transmitted to at least one other terminal, with the at least one other terminal being indicated in the message as the recipient of the communication medium. In a method for assigning a communication medium for a collaborative communication session, a corresponding message is received, and the communication medium is assigned to the at least one other terminal as the recipient of the communication medium. The methods are carried out by appropriately designed apparatuses.

In various aspects of this disclosure, a communication terminal device may be provided. The communication terminal device may include a receiver. The receiver may be configured to receive a message from a first communication device. The communication terminal device may further include a circuit configured to provide a communication device to communication device communication. The communication terminal device may further include a controller. The controller may be configured to determine whether to relay the received message to at least one second communication device. The controller may further be configured to modify the message if the controller determined to relay the received message. The controller may further be configured to relay and transmit the modified message to the at least one second communication device.

Communication terminal device and method for controlling

A method for establishing a communication connection includes transmitting an identification for identifying a first communication device to the first communication device or a second communication device via a packet-switched first communication connection between the first communication device and the second communication devices, and using the identification to establish a circuit-switched second communication connection between the first communication device and the second communication device.

Method for establishing a communication connection and communication device

Methods, systems, and devices for switching internet protocol (IP) flows from a first communication path to a second communication path are disclosed herein. A user equipment (UE) may include an exchange component, a session component, and a communication component. The exchange component exchanges second communication path availability information between the UE and another UE by sending and receiving session initiation protocol (SIP) messages that include second communication path availability information over the first communication path. The session component changes the communication session by re-routing traffic flows to the second communication path based on the exchanged second path availability information. The communication component sends to and receives from the other UE data corresponding to an IP flow over the second communication path.

Communication path switching for mobile devices

A method for ascertaining active sessions may include receiving a request to ascertain active sessions by a session information server; transmitting respective challenges for document contents, which indicate whether sessions are currently active, from the session information server to at least one document management server which has a respective associated communication session server, wherein in the case of precisely one document management server the latter has at least two associated session servers; receiving respective challenge responses from the document management server, which indicate active sessions controlled by the session server associated with the respective document management server or which indicate that such sessions currently do not exist, by the session information server; and transmitting a first response, which indicates one or more active sessions controlled by the session servers associated with the document management server or which indicates that such sessions currently do not exist, by the session information server.
