Abstract: An short message service switching private branch exchange system and a method can reduce costs. The method can include certifying whether a usable DSP exists or not when an office line and a speech path are connected to each other, and transmitting an short message service signal transmitted from the office line to the DSP through a PCM channel if the usable DSP exists. A main processor of the private branch exchange can certify an extension line terminal that will receive short message service, generate an short message service signal having a format corresponding to a kind of the extension line terminal by using the DSP, and transmit the formatted SMS signal to an extension line interface unit of a corresponding extension line terminal. The system switches an SMS signal between an office line and an extension line by sharing the DSP, for example, by time division.

This solution assumes that the mobile device has the capability to operate in at least two modes that include the WLAN mode and one of the cellular carrier modes, such as the GSM, IS-95 CDMA, IS-136 TDMA, and iDEN.

Abstract: A soft switch providing wireless PBX voice services to a local area network (WLAN) is used to extend PBX functionality to the cellular domain. A dual mode remote unit is capable of receiving signals both in the cellular system as well as the WLAN. The cellular system is comprised of a data-bearing path and a voice-bearing path. When the dual mode remote unit is within the WLAN, it communicates both voice over IP (VoIP) signaling as well as session initiation protocol (SIP) control signaling over the WLAN. When the remote unit is outside the WLAN, it communicates voice signaling over the voice-bearing path of the cellular network using a standard cellular voice channel. In parallel, it uses the data-bearing path of the cellular network to transmit SIP control signaling.

Abstract: Users can make landline, wireless and/or internet calls from a conventional landline communication device. If the communication device is on a wireless call, that call may be placed on hold to answer an incoming call on the landline. Likewise, if the communication device is on a landline call, that call may be placed on hold to answer an incoming call on the wireless telephone. Wireless and landline calls may also be conferenced together.

Abstract: The invention relates to a method and a communication system for controlling the user interface of a mobile communication terminal (MKE), which is registered to a communication facility (PBX). Said communication facility uses a stimulus telephone protocol (STP) for controlling a user interface of wire-linked communication terminals (DEG). According to the invention, control information for the representation of the user interface in the mobile communication terminal (MKE) is transmitted by the communication facility (PBX) to the mobile communication terminal (MKE) at least partially by means of a packet-oriented communication protocol (WAP) converted from the stimulus telephone protocol (STP).

Abstract: A power management method and apparatus for a wireless LAN module in a computer system may include a communication sensitivity checking unit for checking a communication sensitivity of a wireless communications channel. If a communications sensitivity is lower than a desired value, a power mode of the wireless LAN module is changed into a sleep mode for a predetermined period of time. After the delay period expires, the wireless LAN module is switched back into a normal mode, and the communications sensitivity is checked again. If the communications sensitivity is acceptable, a data checking unit checks to determine whether there is data to be transmitted/received by the wireless LAN module. If no data needs to be sent, at least the transmission block of the wireless LAN module can be set to the power down mode. Also, if an attempt to set up a communications channel is unsuccessful, the device can be set to the power down mode for a predetermined delay period.

Abstract: The present invention relates to a messaging management system and method for users roaming in a multi-campus enterprise mobile communication environment, wherein the voice messaging is transported only on demand so as to reduce the bandwidth requirement for the digital data network to lower the enterprise's operation cost, and a Voice Messaging System Call-Back (VMS Call-Back) is provided to render the present invention as a user friendly system so as to prevent the users from the problem of uncertain waiting time when the users listen to the voice messages which are transported among different campuses. The system and method of the present invention not only significantly lower the unnecessary transport of the voice messaging but also can operate under the condition of insufficient digital data network bandwidth, which can reduce the cost for network bandwidth and loosen up the operation requirements for the voice messaging system.
