Abstract: A radio communication system assigns one repeater the role of priority repeater, whereupon that priority repeater exclusively relays all messages between one or more portable radios and a base site. The priority repeater monitors various indicia relating to its level of activity, and transitions to a non-priority state when the level of activity exceeds a prescribed threshold. The repeater includes a counter for counting the number of transactions performed since the repeater was assigned the role of priority repeater, wherein the count serves as the activity level measure. These idle repeaters compare the activity level embedded in the message with their own activity level. If an idle repeater determines that its activity level is higher than the current priority repeater's activity level, then it will transmit a message to the priority repeater requesting that the priority repeater relinquish priority status. In this manner, the present invention ensures that a repeater will not deplete its battery during its tenure as priority repeater.

Abstract translation: 无线电通信系统为一个中继器分配优先级中继器的角色，因此该优先中继器专门中继一个或多个便携式无线电和基站之间的所有消息。 优先级中继器监视与其活动水平相关的各种标记，并且当活动级别超过规定的阈值时转变到非优先级状态。 中继器包括一个计数器，用于计数由于转发器被分配了优先级中继器的角色而执行的事务数，其中该计数用作活动级别度量。 这些空闲中继器将消息中嵌入的活动级别与自己的活动级别进行比较。 如果空闲中继器确定其活动级别高于当前优先级中继器的活动级别，则将向优先级中继器发送消息，请求优先级中继器放弃优先级状态。 以这种方式，本发明确保中继器在其任职期间不会耗尽其电池作为优先级中继器。

Abstract: A decoding system processes a received vector r to produce a soft symbol information vector output s including a reliability value for each received code symbol. From the reliability values, clusters of symbols within the received vector r having low reliability are identified and detected. Responsive thereto, the received vector r is permuted to scatter the low reliability symbols within each detected low reliability cluster throughout a given codeword. A decoding generator matrix G is also correspondingly permuted in response to the detection of low reliability clusters of symbols. Utilizing a trellis obtained from the permuted decoding generator matrix G', the permuted received vector r' is then sequentially or otherwise suboptimally decoded.

Abstract: An incoming call towards a ported telecommunications terminal (120) is routed (210) to the donor telecommunications node associated with the dialed directory number without first (40, 180) performing a number portability database (NP-DB) (90) query. Upon determining that the telecommunications terminal associated with the specified called party directory number has been ported, a signal (270) querying the NP-DB is transmitted by the donor node. In response (280), the NP-DB provides a network address representing the gaining telecommunications node (70, 200) to the next-to-last (N-1) switch (100). Utilizing the received network address, the N-1 switch releases the first call connection (210) with the donor telecommunications node and reroutes the call connection to (250) the gaining telecommunications node associated with the received network address.

Abstract: Unwanted transmitter modulation which would otherwise have an undesirable impact at a radio receiving the transmitted signal is detected and cancelled. The radio transmitter includes a phase-locked loop that receives an input signal and a feedback signal. An amplifier stage amplifies an output from the phase-locked loop, and an antenna transmits the amplified signal. A detector detects the transmitted signal and generates the feedback signal. Inclusion of the amplifier stage in the phase-locked loop compensates for undesirable transmitter modulation introduced at the amplifier stage. One example application of the present invention is to vehicular-based radio systems, where the radio transmitter is susceptible to the noise generated by the vehicle electrical system which ultimately results in an audible whine at the radio receiver. The whine heard at the receiver is greatly reduced/eliminated.
