A communications device and method of communicating using a communications device is disclosed for performing device-to-device communications. The communications device is configured to determine in accordance with predetermined conditions whether the communications device is within a coverage area of a mobile communications network, and if the communications device is determined to be within the coverage area of the mobile communications network, to transmit or to receive signals via the wireless access interface to one or more other communications devices in accordance with device to device communications using communications resources of the wireless access interface allocated according to a first mode in which the mobile communications network performs resource allocation.

A wireless communication system includes a base station and direct wave communication stations that communicate with the base station. At least one of the base station and the direct wave communication stations includes a number-of-bands switching unit that switches, on the basis of a communication state, a number of bands for direct wave communication, by dividing a band for direct wave communication. One of the plurality of direct wave communication stations receives a narrowband carrier in the divided band.

Optimal network resource consumption by dynamically controlling media bursts in Simultaneous PoC (Push-To-X (Push-To-Voice/Video/etc.) Over Cellular) calls. Embodiments disclosed herein relate to wireless communication networks, and more particularly to PoC calls performed using wireless communication networks. Embodiments herein disclose methods and systems for optimal network resource consumption by dynamically controlling media bursts, when a user is participating in simultaneous PoC sessions. Embodiments herein disclose methods and systems for optimal network resource consumption by enabling a user to selectively enable/disable multiple PoC sessions using MBCP “Activate” and “Deactivate” messages.

The disclosed technology is generally directed towards, for interworking function interworking group call services, configuring each of the interworking groups with a separate group home server, with the servers coupled to one another via an interworking function. The interworking function receives a floor taken message from one server, and, in response, obtains a floor grant from the other server, which facilitates communication from a device to which the floor was granted to other devices, including devices associated with the other server. If the interworking function receives colliding floor taken messages from both servers, the interworking function performs mediation to determine which server/user has a higher priority level. The interworking function acknowledges the floor taken message to the higher priority server, and sends a floor request (with high priority) message to the other server, which triggers a floor revoke message to a device on the lower priority side.

A rugged, ergonomic integrated telecommunications handset includes an electronic controller that interoperates and controls the universal remote control (URC), which connects to multiple radios simultaneously. The controller downloads options which are implemented by the controller. The handset has an ability to vibrate in a silent mode, and has a memory capacity, as well as GPS capacity. Ergonomically, the handset has a pair of side arrays of protruding ribs, which enhance gripping, preventing the handset from falling out of the user's hands, even if the user has gloves on in inclement weather conditions in the field. While compatible with the latest radio system software defined dual net and dual channel radio equipment, the handset is also backward compatible with single radios or with two or more separate radios, and may communicate using Bluetooth.

Disclosed herein is a method and a wireless communication device for performing the method. The method comprising: sending to an IOPS MC system associated with one or more radio access nodes of a cellular communications system, an IP connectivity announcement request or an IP connectivity group announcement request for announcing availability of the wireless device to one or more other devices served by the IOPS MC system; and receiving, from the IOPS MC system, an IP connectivity announcement response or an IP connectivity group announcement response.
