摘要： A selective call system provides dynamic group calling by transmitting a paging message (FIG. 10) to each data communication receiver in a defined group. The paging message comprises a group call address (1040) and frame (1050) and phase (1060) information identifying when the group message will be transmitted. The group call message is then transmitted (326, 328) in the assigned frame and phase. When the paging messages comprising the group call address are received (1904) by the data communication receivers, the group call address is decoded and temporarily stored (1910) as an address of the receiver. Within the identified frame and phase, address correlation with the group call address is attempted (1918, 1926) and the group call message, when found (1920), is received and decoded (1922) as a paging message. After reception of the group call message, the group call address and associated stored information is erased (1924).

摘要： A messaging system capable of transmitting messages to receivers which roam between coverage areas. In one configuration, a coverage area (100) is divided into a plurality of zones (110). A single simulcast system identification (SSID) number is assigned which consists of a local identification number which identifies the coverage area (100), a zone identifier which identifies a zone (110) within the coverage area, traffic splitting flags and a frequency. For larger roaming areas, a network (200) is defined as consisting of a plurality of service areas (210) and is identified by network roaming identification information (NRI). NRI information and/or SSID information is stored in a receiver according to desired coverage and like information is transmitted in the corresponding zone or service area.

摘要： Network roaming information (NRI), which comprises identifies a network (200) and a service area (210) within the network (200), a receiver address, is transmitted in a network (200) during a predetermined number of time slots of a signal, whereby the signal is transmitted in consecutive cycles, each cycle comprising a plurality of consecutive time slots. The placement of the NRI in the transmitted signal is made to be predicted by a receiver so that the receiver can compute an expected time slot location of a NRI to be compared with a stored NRI. The placement of the NRI is made according to an algebraic relationship between moduloN of the transmission frequency of the signal, moduloN of the order of the cycle, and moduloN of a portion of the NRI, wherein N is an integer.

摘要： A communication receiver (106) receives an address code word (1800) of a transmitted message, the message comprising the address code word (1800) and an associated data portion (1610), the address code word comprising an address portion (1802,1804). The communication receiver (106) corrects (2104) up to a predetermined number of bit errors in the received address code word (1800). The communication receiver (106) can conserve power following a failed correction of the address code word (1800). Alternatively, the communication receiver (106) compares (2108,2111) the address portion (1802,1804) of the corrected address code word (1800) to at least one predetermined subscription address (1704,1706). The communication receiver (106) can conserve power following a determination of no match (2110,2114,2308) between the address portion (1802,1804) of the corrected address code word (1800) and the at least one predetermined subscription address (1704,1706).

摘要： A technique is used in a simulcast radio communication system (200) for providing improved local time information. The technique includes, in a fixed portion (300) of the simulcast radio communication system (200), alternatively transmitting in a radio signal a first local time and a second local time in a predetermined protocol position that occurs periodically in a signaling protocol, wherein the first local time and second local time differ by a time zone interval. A radio (500) that receives the radio signal presents local time to a user in manner that indicates the first and second local times.

摘要： In a battery powered selective call receiver receiving a synchronous signal, a battery saving method extends battery life by optimizing the amount of time the receiver circuit is activated when searching for the signal after previously acquiring synchronization. The battery saving method allows for turning the selective call receiver on without activating the receiver circuit. The receiver circuit is activated at a time later than the energization of the selective call receiver, where the time of activation of the receiver circuit is determined in response to the time passed since synchronization was last acquired and the system signal stability.

摘要： A selective call paging receiver for receiving analog voice information converts the analog information to digital information and stores the digital information in a memory of the paging receiver. In a first embodiment, the paging receiver includes a hardware controlled decoder and an audio producing module. The memory is divided into a plurality of fixed storage areas to allow the decoder to store a digitized voice message in a fixed storage area. If the storage capacity of the fixed storage area is not filled, the audio producing module fills the remainder in a predetermined bit pattern. In a second embodiment, the paging receiver includes a microprocessor controlled decoder. The microprocessor stores a digitized voice message in the memory, depending upon the length of the voice message, thus eliminating the fixed storage area.

摘要： A selective call receiver (111) receives a synchronous selective call signal (99) having synchronization portions (102 and 104) and a frame identification portion (106). Upon finding the signal the selective call receiver's bit and frame synchronizers (126 and 128) synchronize to a frame (100) of the signal and a frame ID decoder (130) decodes the frame ID (106). A comparator (136) compares the received frame ID (106) with an ID (142) assigned to the receiver, and optionally a first and second mask (134A and 134B) to determine the number of frames until an occurrence of a desired frame and conserves power until the occurrence of the desired frame (188).
