Abstract:
PROBLEM TO BE SOLVED: To obtain a method and apparatus for providing broadcast messages in a communication network. SOLUTION: The present invention is a novel and improved method for providing broadcast short message services (SMS) in a communication network. It is also a method and apparatus that performs the successful transmission of the broadcast message while minimizing the effect caused by providing the short messaging service on overall system capacity. Messages to be broadcast to a group of users are provided, by broadcast page generator (20), to a broadcast message buffer (24). The timing of the message transmission is controlled by a page transmission controller (34), and the message is modulated on to an appropriate channel by modulator (26). COPYRIGHT: (C)2006,JPO&NCIPI

Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus for formatting data of various types into an original structure for transmission in various rates in digital communications. SOLUTION: Data for a transmission format may also be audio data supplied by a vocoder (14) or secondary traffic of a different type. Data structured into a frame of a predetermined time cycle are transmitted by a microprocessor (18). The data frame is structured into one of several data rates according to data. Vocoder data are supplied in one of several rates by the vocoder (14) and structured with the frame according to a predetermined format. The frame may also be formatted into a highest frame data rate while sharing vocoder data including non-vocoder data. Non-vocoder data of a different type may also be structured into the highest frame data rate. Additional control data are supplied to the data frame and may also be effectively utilized for various aspects of recovery in transmission and reception. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a new and improved method and its device for formatting transmission vocoder data, non-vocoder data and signaling data. SOLUTION: The method and the device are the ones for constituting various types of data into a format with an original structure for transmission by various rates. Data for a transmission format can be voice data supplied by a vocoder (14) or a different type secondary traffic. Data made into a structure with a prescribed time periodical frame is transmitted by a microprocessor (18). A data frame is made into a structure to be one of some data rates in accordance with data. Vocoder data is supplied by one of the rates by the vocoder (14) and made into a structure by the frame in accordance with a prescribed format. The frame is formatted to be the fastest frame data rate while sharing vocoder data having non-vocoder data. The different type non- vocoder data can be made into a structure to be the fastest frame data rate. Additional control data is supplied to the data frame and, then, is useful for the various aspects of recovery in the case of transmission and reception.

PROBLEM TO BE SOLVED: To provide a method and a system to transmit a broadcast message suitably while minimizing an impact of offering a short message on an entire system capacity in a small message service (SMS) broadcasted in a communication network. SOLUTION: A message broadcasted to a user group is provided to a broadcast message buffer by a broadcast page generator. The timing of a message transmission is controlled by a page transmission controller. Then, the message is modulated on an appropriate channel by a modulator. COPYRIGHT: (C)2005,JPO&NCIPI

SOLUTION: This is a new and improved method to provide a short message service (SMS) broadcasting in the communication network. The object is to provide a method and a device which well transmit a broadcasting message keeping an effect of sending a short messages in a total system capacity in the minimum. Messages broadcasted to an user group are sent to a broadcasting message buffer (24) by a broadcasting page generator (20). Timing of the message transmission is controlled by a page transmission controller (34). Afterwards, the messages are modulated on an appropriate channel by a modulator (26). COPYRIGHT: (C)2003,JPO
Abstract:
High rate CDMA wireless communication is obtained by forming a set of individually gain adjusted subscriber channels. Each channel has a set of orthogonal subchannel codes having a small number of PN spreading chips per orthogonal waveform period. Preferably, the set of sub-channel codes are comprised of four Walsh codes, each orthogonal to the remaining set and four chips in duration. It is also preferred that pilot data be transmitted via a first transmit channel and power control data transmitted via a second transmit channel. The remaining two transmit channels are used for transmitting non-specified digital data including user data or signaling data, or both. One of the two non-specified transmit channels may be configured for BPSK modulation and the other for QPSK modulation.
Abstract:
The structure of a time-multiplexed physical channel is used to time inter-frequency or inter-system search excursions. A mobile station that receives an instruction to perform a search excursion prepares for the search excursion by detecting the first radio frame of a message frame. Transport format combination indicator bits are extracted from the first radio frame and stored. After the search excursion is performed, the mobile station recalls the stored indicator bits and uses the indicator bits to decode other radio frames of the message frame.
Abstract:
Systems and methods for switching among networks (e.g., heterogeneous) and inter-working between a source access system and a target access system, by implementing tunnelling from the AT to the target access system via the source access system. An inter-system handoff control component can facilitate setting tunneling by the mobile unit to the target access and/or between the source access system and the target access system - wherein signaling/packeting associated with the target system can be transferred over the source system.
