摘要： Methods and systems for assigning a wireless communication device to a carrier frequency are presented. In an exemplary embodiment, a radio access network (RAN) radiates to define one or more wireless coverage areas using at least two different carrier frequencies. A given wireless communication device (WCD) seeks to engage in a call, and accordingly transmits a probe message to the RAN. In response to receiving the probe message, and based at least on information associated with the probe message, the RAN determines an initial carrier frequency assignment for the given WCD. Preferably, this initial carrier frequency assignment is performed to balance load across at least some of the at least two different carrier frequencies. The RAN then transmits an indication of the carrier frequency assignment to the given WCD. The given WCD may then tune to the assigned carrier frequency and conduct communications using the assigned carrier frequency.

摘要： Methods and systems for carrier frequency management based on slot contention are provided. A radio access network (RAN) may radiate on one or more carrier frequencies to define wireless coverage areas. Each wireless coverage area may provide network access for one or more wireless communication devices (WCDs). In order to efficiently manage these carrier frequencies, the RAN may measure a slot contention metric for each carrier frequency. Based on the measured slot contention metrics, the RAN may perform a carrier frequency management function affecting at least one of the carrier frequencies. Carrier frequency management functions may include, but are not limited to, assigning a WCD to a carrier frequency, taking a carrier frequency out of service, and placing a new carrier frequency in service.

摘要： Disclosed herein is a mechanism to help improve message waiting notification. In accordance with the mechanism, when a RAN transmits an MWI to a mobile station after unsuccessful call setup paging of the mobile station, the RAN will transmit the MWI at a higher power level than the RAN used for transmitting the call setup paging. Using a higher transmission power specifically for the MWI should help the MWI reach the mobile station, particularly in a scenario where a reason for call setup paging failure was noise on the air interface. Consequently, the disclosed mechanism should help improve user experience by increasing the likelihood that mobile stations will receive and process MWIs soon after the associated voice mail messages are left.
摘要翻译：这里公开了一种帮助改善消息等待通知的机制。根据该机制，当RAN在移动台的呼叫建立寻呼不成功之后向移动台发送MWI时，RAN将以比用于发送呼叫建立寻呼的RAN更高的功率电平发送MWI。专门用于MWI的更高的发射功率应该有助于MWI到达移动台，特别是在呼叫建立寻呼失败的原因是空中接口噪声的情况下。因此，所公开的机制应该有助于通过增加在相关联的语音邮件消息被留下之后移动台将很快接收和处理MWI的可能性来改善用户体验。

摘要： Methods and systems are provided for using mobile-station revision ratio to improve reverse-link performance. An access node provides service to first and second subsets of access terminals, the first operating according to IS-856, Rel. 0, the second according to IS-856, Rev. A. The access node periodically transmits a reverse activity bit (RAB) to the access terminals, and also periodically computes a ratio of (a) either (1) the number of access terminals in the first subset or (2) the number of access terminals in the second subset to (b) a total number of access terminals in the first and second subsets, and transmits the ratio to at least the first subset. When the RAB is set, the access terminals in the first subset perform a ratio test by comparing the ratio with a threshold, and decrease their reverse-link data rates without reference to any reverse-link transitional probabilities when the computed ratio passes the ratio test.

摘要： Disclosed herein is a method and corresponding system to help a wireless communication device (WCD) stay within a home system's network coverage after an access attempt failure. According to one embodiment of the method, a WCD receives a channel list message (CLM) in a given coverage area and transmits an access attempt on a carrier listed in the received CLM. Upon the failure of such an access attempt, the WCD may transmit an additional access attempt on another carrier listed in the received CLM, rather than switching over to a roaming system. According to another embodiment, a WCD receives a channel list message (CLM) in a given coverage area and transmits an access attempt on a carrier listed in the received CLM. Upon the failure of such an access attempt, the WCD may transmit an additional access attempt on another carrier not listed in the received CLM, rather than switching over to a roaming system. According to yet another embodiment, a WCD receives a CLM from a first coverage area and thereafter moves into a second coverage area and subsequently receives a CLM from the second coverage area. The WCD transmits an access attempt on a carrier listed in the second CLM and upon the failure of such an access attempt, transmits an additional access attempt on a carrier listed in the first CLM.

摘要： Methods and systems for reducing the latency of instant communication session establishment are presented. According to various preferred embodiments, a RAN, may receive a setup request message via a packet-switched network. The RAN may determine, from a quality of service (QOS) indication contained in the setup request message, that the setup request message is requesting establishment of a instant communication session. The RAN may further determine an intended destination wireless communication device (WCD) for the setup request message. Based on the QOS indication and/or a profile indicating the destination WCD's capabilities, the RAN may pre-allocate resources for the instant communication session in parallel to paging the destination WCD. In this way, the latencies associated with these procedures are overlapped, thus reducing the overall latency of instant communication session establishment.

摘要： Methods and systems for periodically transmitting traffic channel assignment (TCA) messages in a radio access network are disclosed herein. An exemplary method involves (a) periodically transmitting a capsule that includes one or more TCA messages, wherein an async timer specifies a period that is used to periodically transmit the capsule; and (b) using one or more backhaul-latency indicators as a basis for determining the period that is used to periodically transmit the capsule. The method may further comprise periodically repeating (b) in order to dynamically update the async timer to reflect changes in backhaul latency.

摘要： A cellular wireless communication network transmits spread spectrum signals that are spread by a pseudonoise (PN) code with any of a plurality of PN offsets, such that different coverage areas use different PN offsets. In each coverage area, the network transmits a plurality of forward link channels, each defined by a respective Walsh code, without transmitting a pilot signal. A wireless communication device (WCD) begins operating in a given coverage area and determines the PN offset used in the given coverage area by receiving a forward link signal having a Walsh code of a sync channel, paging channel, or other channel that transmits a broadcast message. The WCD selects a target bit sequence that would be expected to be included in the broadcast message. The WCD finds an effective PN offset that enables the WCD to despread the forward link signal and recover the target bit sequence.
