摘要： During a communication session, a first BTS transmits a first forward link signal that is received by a first mobile station, a second BTS transmits a second forward link signal that is received by a second mobile station, the first mobile station transmits a first reverse link signal that is received by the first BTS, and the second mobile station transmits a second reverse link signal that is received by the second BTS. One or more control parameters for the forward and/or reverse link signals are selected based on a receiver sensitivity of the first mobile station and/or second mobile station. In one example, a target error rate of the first reverse link signal and a maximum transmit power level of the second forward link signal are selected based on the receiver sensitivity of the second mobile station.

摘要： A radio access network (RAN) may radiate to define a wireless coverage area that is configured to provide wireless coverage to wireless communication devices (WCDs). If the utilization of the wireless coverage area is below a low-utilization threshold, the RAN may begin transmitting noise frames in the wireless coverage area. In doing so, the transmitted signal strength of the wireless coverage area may increase, which in turn may increase the likelihood that the WCDs can acquire and use the wireless coverage area.

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 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： What is disclosed is a wireless access system. The wireless access system includes a wireless access control system configured to maintain an available pool of Media Access Control Identifiers (MAC IDs) for subsequent use by a base station, remove a portion of the MAC IDs from the available pool, and use the portion of the MAC IDs for wireless communications between a wireless transceiver of the base station and a plurality of user devices. The wireless access control system is configured to determine that the available pool of the MAC IDs is insufficient, and in response, select a set of the user devices based on at least wireless signal strength. The wireless transceiver of the base station is configured to instruct the selected set of the user devices to not use the base station for the wireless communication, and in response, the wireless access control system is configured to return ones of the MAC IDs used by the selected set of the user devices to the available pool.

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 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： 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.
