摘要： The wireless CDMA system includes a base station which generates a configuration channel as one of the forward control channels. The message slots in the configuration channel only include overhead messages. The base station also generates at least one other forward control channel, but these other forward control channels do not need to include overhead messages in any of their message slots. The mobiles in the system determine the location of the configuration channel from information in a sync channel generated by the base station. By camping onto the configuration channel, a mobile can quickly obtain the overhead parameters in the overhead messages. Because obtaining overhead parameters and keeping an updated version of the overhead parameters is an important factor in overall performance, the significant decrease in overhead message access time provided by the provision of the configuration channel greatly improves performance.

摘要： The possibility of incompatibility between wireless communication system stations having the most recent protocol revisions is addressed by transmitting from the base station to a mobile station characteristics that identify a mobile station group that is restricted to using less than the most recent protocol revision. Using less than the most recent protocol revision may involve using an earlier revision or a subset of the most current protocol revision. This permits a base station to direct mobiles to avoid using protocol revisions or features of protocol revisions that have been insufficiently tested or that have a history of problems for a particular base station/mobile station combination.Additionally, when a mobile station receives a message from a base station identifying which mobile stations are subject to what set of restrictions, the mobile station then sends a message to the base station requesting service that matches the restrictions that were identified associated with the group to which the mobile station belongs.

摘要： A paging signal is detected where the paging signal is intended for a mobile-telephone having a paging channel frequency that is different than a paging channel frequency associated with a concentrator. A base station transmits a base station-to-mobile-telephone (BS-MT) paging message by including such BS-MT paging message in a base station-to-concentrator (BS-C) paging message. The BS-MT paging message includes a message portion and a mobile-telephone identifier portion, wherein the mobile-telephone identifier portion indicates the mobile-telephone to which the BS-MT paging message is intended. The BS-C paging message includes the MT paging message and a concentrator identifier portion for indicating the concentrator to which the BS-C is intended. The BS-C paging message is transmitted over a paging channel on a frequency f1 associated with the intended concentrator (i.e., concentrator through which the mobile-telephone is linked to the base station). The intended concentrator detects the BS-C paging message by monitoring its associated paging channel on frequency f1 for a BS-C paging message with a concentrator identifier portion indicating the concentrator. Upon detecting its BS-C paging message, the concentrator parses the BS-MT paging message from the BS-C message and transmits the BS-MT paging message to the intended mobile-telephone using a paging channel on frequency f2 being monitored by the mobile-telephone.

摘要： A high priority and/or emergency overload access control system treats a wireless unit as a higher priority wireless unit when the wireless unit is attempting to access a wireless communications system with a high priority call, such as an emergency call. For example, the overload access control system can recognize if the wireless unit is attempting to initiate a call to an emergency number. If so, the wireless unit can perform a persistence test as an emergency class (e.g. overload class 10-15) wireless unit in attempting to access the wireless communications system. Thus, the wireless unit will experience an increased probability of passing the persistence test and thereby reducing the persistence delay in attempting to access the wireless communications system with the emergency call.
摘要翻译：当无线单元试图访问诸如紧急呼叫的高优先级呼叫的无线通信系统时，高优先级和/或紧急过载接入控制系统将无线单元视为较高优先级的无线单元。例如，过载访问控制系统可以识别无线单元是否尝试发起对紧急号码的呼叫。如果是这样，则无线单元可以在尝试访问无线通信系统时作为紧急类（例如，过载类10-15）无线单元执行持久性测试。因此，无线单元将经历增加的持久性测试的概率，从而减少尝试在紧急呼叫中访问无线通信系统时的持续延迟。

摘要： Wireless service option number assignments are divided into related groups. One group comprises voice service options: #1 (TIA/EIA-96-C “basic” 8k), #3 (IS-127 EVRC 8k), and #17 (IS-733 13k) which refer to different voice rates. Other groups may include data services; however, several subgroupings are possible, and may be used to keep the size of each group at a manageable level. The TIA/EIA-96-C is hereby incorporated by reference. Definitions for each related group of service options (i.e., bitmap) would be maintained in a standard such as TSB58. The TSB58 standard is hereby incorporated by reference.

摘要： A procedure for triggering a handdown or a handoff a mobile station served by a base station of a cellular wireless communication system. A tolerable path loss for signal links between the base station and a mobile station located within the base station's cell, is initially determined. A control signal is radiated at a known transmit power level from the base station over its cell. A receive power level threshold is determined for the control signal for reception by the mobile station, according to the transmit power level and the tolerable path loss. A handoff of the mobile station is triggered after deriving the received power level of the control signal at the mobile station, and determining that the received power level is less than the receive power level threshold. In one embodiment, a mobile station reports to a serving base station only after the former determines that the received power level of a control signal from the base station is less than a threshold level initially provided to the mobile station by the base station. The procedure is applicable, e.g., to base station cells of a first CDMA cellular system which cells border on cells of an analog (AMPS) or a second CDMA cellular system.

摘要： A method for allocating traffic between multiple carriers in a wireless communications system measures loading on the communication system and selects an appropriate carrier from multiple carriers, based upon the loading measured. A first carrier is selected if the load on the first carrier is lower than or equal to the lowest loading of any supplemental carrier among the multiple carriers. If the load on the first carrier is not lower, then the subscriber may be assigned either to a supplemental carrier or the first carrier. The carrier assignment of the subscriber depends upon a predetermined threshold, which preferably considers actual or estimated differential interference between the first carrier and the supplemental carrier.
