Abstract: To realize a wireless communication system capable of keeping a beacon interval fixed, keeping transmission quality, and performing intermittence reception without fail. A wireless communication management device includes and transmits beacon time period information in a main beacon and a sub beacon. Then, a wireless terminal device divides transmission data based on the beacon time period information so that the transmission of the transmission data is finished before the transmission of a main beacon is started. Thereby, overlap of transmission timings of the beacon and the transmission data can be prevented and the beacon interval can be made fixed. This can keep transmission quality, makes the wireless terminal device to perform intermittence reception without fail, and improve the entire data transmission efficiency of the system.

Abstract: Methods to create a cellular-like communication system, such as a Wireless Private Branch Exchange (WPBX), which includes mobile devices such as standard cordless phones (handsets), particularly, mobile devices utilizing the Bluetooth short-range wireless communication protocol. The methods provide seamless and reliable handoff of sessions between Base Stations while the mobile device is moving between picocells, by implementing a high-level of synchronization between the Base Stations and the Switch. Base Stations of picocells having small coverage areas communicate with the handsets. The communication protocol is divided into a low-level protocol performed by the Base Stations and a high-level protocol performed by the Switch connected to all the Base Stations. The methods support mobile computing or telephony devices and communication protocols, which are not specified to handle handoffs of sessions while moving between Base Stations coverage areas in a data, voice or telephony wireless network.

Abstract: A paging indicator deciding method of a mobile communication terminal in which a threshold value for deciding a paging indicator is variably set according to a SNR of a pilot channel. If the SNR of the pilot channel is in a range that a false alarm rate (FAR) has a large value, the mobile terminal determines a threshold value so that it can have the greatest value in a range that a miss probability (MP) does not exceed the standard value. If the SNR of the pilot channel is not in the range that the SNR has the large value, the mobile terminal determines a threshold value to obtain the smallest MP in a range that the FAR is not further increased.

Abstract: A method, system and apparatus in a wireless communications system selectively utilizes the Internet for the transmission of information. In a first embodiment, a subscriber can activate an Internet call forwarding (ICF) supplementary service (SS). From the subscriber's Mobile Station, an ICF message is transmitted to and stored in the subscriber's Home Location Register (HLR). The ICF message may optionally designate an Internet protocol (IP) address destination and may optionally activate other features pursuant to the data type received. For example, the ICF message may request that only fax/data calls or only calls that would otherwise incur a long distance charge be forwarded over/through the Internet. In operation, an incoming call to a Gateway Mobile Services Switching Center (GMSC) causes the GMSC to interrogate the called party's HLR. The information in the incoming call is then forwarded either over/through the Internet or over the PSTN based on the features activated by the ICF message.

Abstract: A geographical web browser allows a user to navigate a network application such as the Word Wide Web by physically navigating in geographical coordinates and roaming through coverage areas of cellular base stations, wireless LANs, microcells, and other such broadcast domains. A mobile unit communicates with a network server via an air interface that supports wireless packet data. A network server uses a set of user preferences to filter a set of server-side information in accordance with a user's interest. A content-selective information filter performs a network server-side search to identify content that matches the user's preferences and automatically downloads the information to the mobile unit based on a geographic event.

Abstract: A system and a method of controlling transmitter power in a wireless communication system in which user data is processed as a multirate signal having a rate N(t) and in which the user data signal having rate N(t) is converted into a transmission data signal having a faster rate M(t) for transmission. The transmission power is adjusted on a relatively slow basis based on quality of data received by a receiver of the transmitted data. The transmitter power is determined as a function of N(t)/M(t) such that a change in the data rate in the multiple channels or the rate of the transmission data signal is compensated in advance of a quality of data based adjustment associated with such data rate change. Preferably, the user data signal having rate N(t) is converted into the transmission data signal having the faster rate M(t) by repeating selected data bits whereby the energy per bit to noise spectrum density ratio is increased in the transmission data signal.

Abstract: An initial channel access message such as a Random Access Channel (RACH) preamble is used to mean that not only that a channel access has been requested by a mobile station (500) but also that a particular type of service has been requested. By associating a type of service (e.g., Dispatch, web browsing, etc.) with the particular signature that is used to form the RACH preamble it speeds up the service negotiation process. Both the communication system (600) and the MS (500) know what service is associated with which signature, so as soon as a RACH preamble is received by the system, it can determine if it has the resources available to accommodate the request.
