摘要： A radio communication apparatus for use in a time division multiple access (TDMA) communication system prevents signals from being transmitted through a transmitter in response to recognition that the transmitter operates during an unassigned time slot. A controller is utilized to recognize that the transmitter operates during the unassigned time slot. Power to the transmitter is disconnected in response to the recognition.

摘要： In a mobile station apparatus of this invention, when a first offset is captured by a search operation performed by a first PN code search mode, it is checked, on the basis of the SID broadcasted from the corresponding base station through a sync channel, whether a base station of a desired carrier is captured. If a base station of an undesired carrier is captured, a second PN code search mode receives a neighbor list message broadcasted from the base station of the undesired carrier through a paging channel, and causes a search receiver to perform a search operation, excluding spreading code offsets notified by the message.

摘要： A dual mode cellular radio communication apparatus having a received signal strength measuring function is disclosed. The measured strength of the signal may be corrected when the apparatus operates in the digital mode. The value of corrected strength may be used for indicating the received signal strength to a user of the apparatus and for reporting the received signal strength to a base station. Similarly, the measured strength of the signal may be corrected for indicating the received signal strength to a user of the apparatus when the apparatus operates in the analog mode.

摘要： A radio communication apparatus of this invention includes a mode designation switch for selectively designating and inputting a desired mode from an analog mode and a digital mode, and a mode storage circuit for storing the desired mode designated and input by the mode designation switch and has a mode setting control function, a mode comparison function, and a mode change control function. In order to establish a radio link, control is performed to set a mode for transmitting a communication signal in accordance with the desired mode stored in the mode storage circuit. After the start of transmission of the communication signal, the mode comparison function compares the mode set by the mode setting control function with the desired mode stored in the mode storage circuit. If these modes are determined not to coincide with each other by the mode comparison function, control is performed to change the mode set by the mode setting control function to the desired mode stored in the mode storage circuit in accordance with the mode change control function.

摘要： A mobile radio communication apparatus includes a common channel detecting unit which judges whether or not a paging channel and an access channel which are assigned to one base station are common based on a predetermined parameter (CPA) which is transmitted from the base stations. If the CPA indicated a predetermined value indicating that the paging channel and the access channel are common channel, then a memory stores that information representing the base station which transmits the strongest level of all the received access channel at an input of a receiver of the mobile radio communication apparatus.

摘要： There is provided a mobile radio communication device which is designed to prevent dishonest applications by using a management table (30) for storing a plurality of MINs and count values as authentication parameters corresponding to the MINs and effecting the authentication procedure at the time of radio connection to a base station. Whether or not an input MIN is already set in the management table (30) is determined at the time of MIN setting operation, and if it is already set, it is determined that the setting operation is a resetting operation and the already set MIN and count value are kept held as they are. On the other hand, if the input MIN is not set in the management table (30), whether or not a MIN having a count value of "0" is set in the management table (30) is determined, and if it is set, an input MIN is set in place of the above MIN, and if it is not set, an input MIN and the initial value "0" of the count value are set in an available area of the management table (30).
