An application server for use in a telecommunications network. The application server comprises a receiver for receiving an indication of a call setup or message to a fixed line telephone number of a subscriber, a determining unit for determining whether a mobile station of the subscriber is connected to a home femtocell of the subscriber, and a redirection unit for causing the call setup or message to be redirected towards the mobile station if the subscriber's mobile station is connected to the home femtocell.

Provided are methods, apparatuses and a system for synchronizing call media and content. In a process of playing call media to a user and displaying content associated with the call media, a terminal acquires new call media from a call media server and acquires, after querying a synchronization server for content information corresponding to the new call media, content associated with the new call media from a content server, respectively, in response to a user operation. The terminal plays the new call media to the user, and displays the content associated with the new call media simultaneously.

A wireless base station device includes a test request unit that, upon receipt of a line test request from a host station side, transmits an implementation request for a line test to a wireless terminal station device and a test response unit that transmits at least one of a terminal identification code returned from the wireless terminal station device and a terminal identification code and a line test result of the wireless base station device to the host station side. A wireless terminal station device includes a test implementation unit that receives the implementation request for the line test from the wireless base station device, executes the line test between the wireless terminal station device and the subscriber home, and acquires the line test result and a test-signal communication unit that transmits at least one of a terminal identification code returned from a device on the subscriber home side and a terminal identification code and a line test result of the wireless terminal station device to the wireless base station device.

A call forwarding device based on an IMS includes a terminal and an IMS communication system connected to the terminal. The IMS communication system is respectively connected to an IMS special service number device, an IMS user database and an IMS maintenance device. After the terminal establishes a communication with the IMS special service number device, a forwarding condition and a forwarding number set through an IVR, and a calling number and a called number of the terminal are saved in the IMS user database. When the calling number of the terminal dials the called number, the IMS communication system detects a status of the called number, and a communication is established between the calling number and the forwarding number of the terminal according to the forwarding condition.

A wireless network is provided that includes a base station and subscriber stations that communicate with the base station using radio frequency (RF) time division duplex (TDD) signaling. The base station may establish medium access control (MAC) connections with each station. The base station monitors communications with the stations and, in accordance, assigns stations or MAC connections to modulation groups. The base station transmits signals on MAC connections or to stations in a modulation group in adjacent TDD slots within a TDD frame. The base station may receive access requests from the stations, evaluate traffic requirements for the stations, and determine a longest downlink portion for the stations. The base station then allocates downlink and uplink portions of a TDD frame according to the length of the longest downlink portion.

In a process of playing call media to a user and displaying content associated with the call media, a terminal acquires new call media from a call media server and acquires, after querying a synchronization server for content information corresponding to the new call media, content associated with the new call media from a content server, respectively, in response to a user operation. The terminal plays the new call media to the user, and displays the content associated with the new call media simultaneously.

A deployable interoperable communication system is provided that provides integrated and redundant communications between radio, cellular, and landline phone platforms for voice, text, video, and data transmission. The interoperable communication system integrates with existing radios, cellular phones, and emergency management communications systems illustratively including: command and control, incident management, video management, Physical Security Information Management (PSIM), and more. The interoperable communication system enables any caller to establish communication with another user or radio channel with no knowledge of technology or frequency assignment, and without need to modify or otherwise manipulate the calling device, such as re-programming a land mobile radio. Voice prompts queue the caller with instructions to connect to appropriate line or radio channel with a few simple button presses. None of the transmission is clipped; the caller has no need to hesitate to speak after pushing their talk button.

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 POTS alternative including an uninterruptible power supply (UPS), a router, a modbus converter for connecting the router to the UPS to monitor conditions of the UPS, a gateway for providing connections to one or more POTS-based customer premises equipment through the modbus converter to the router and directly to the router. The router includes a plurality of SIM cards, each SIM card for connecting to one cellular service provider among a plurality of cellular service providers. The router automatically connecting to a cellular service provider among the plurality of cellular service providers providing the strongest cellular signal and switching from the cellular service provider to a different cellular service providers when the different cellular service provider provides a stronger cellular signal when the cellular service provider no longer provides the strongest cellular signal.
