    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: 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: Disclosed is a mechanism for efficient channel selection in a wireless communication system. A wireless communication device (WCD) receives from a radio access network (RAN) a channel list message that specifies channels on which the RAN communicates in a coverage area. Further, the WCD receives from the RAN for at least a given one of the channels an expected delta value indicating an expected difference in signal strength between that channel and another channel. The WCD may then take an actual measurement of signal strength on the other channel and apply the expected delta to predict a signal strength of the given channel. Based on the predicted signal strength being threshold low, the WCD may then select a channel other than the given channel on which to communicate with the RAN, and the WCD may then communicate with the RAN on the selected channel.

    摘要: Methods and systems are defined that support, in a radio access network, measuring the latency between the radio access network and each respective access gateway of a plurality of access gateways. From these measurements, a list of access gateways, rank ordered from lowest to highest latency, is created. If the radio access network receives an incoming call indication designating that an associated incoming call is latency-sensitive, the radio access network will preferably assign the incoming call to an access gateway that is one with a measured respective round trip latency less than or equal to a median measured respective round trip latency. Additionally, the radio access network maintains a profile for at least some wireless communication devices that use its services. When the radio access network receives an incoming call indication for a wireless communication device, the radio access network preferably determines, from the wireless communication device's profile, if the wireless communication device has a history of heavy network usage. If the wireless communication device has a history of heavy network usage, the radio access network preferably assigns the incoming call to an access gateway that is one with a measured respective round trip latency greater than or equal to the median measured respective round trip latency.

    摘要: Described herein is a method and corresponding radio access network (RAN) arranged to dynamically control, based on vehicular traffic monitoring data, allocations of network capacity in a wireless coverage area. More particularly, according to the method the RAN may receive vehicular traffic monitoring data, perhaps from a service provider such as a vehicular traffic monitoring agency. Based on the received vehicular traffic monitoring data, the RAN may adjust a limit on extent of capacity allocated to new call originations and/or a limit on extent of capacity allocated to handoffs in a wireless coverage area of the RAN. According to one aspect of the method, the RAN may adjust network capacity allocations in the wireless coverage area based on a specified vehicular traffic speed. According to another aspect of the method, the RAN may adjust network capacity allocations in the wireless coverage area based on a specified vehicular traffic obstruction.

    摘要: During an initial part of a communication session, a transmitting node transmits digital data over a first air interface channel to a receiving node, using a first data rate and a first level of repetition. A degradation in quality of the communication session is detected. During a subsequent part of the communication session, the transmitting node transmits digital data over the first air interface channel as before but also transmits the digital data over a second air interface channel, using a second data rate and a second level of repetition. The second data rate is higher than the first data rate, and the second level of repetition is higher than the first level of repetition. Thus, during a given transmission period, the transmitting node may transmit a voice frame once over the first air interface channel and N times over the second air interface channel.
