Abstract: Methods and devices for mitigating the impact of handoffs to non-preferred wireless coverage areas are presented. In particular, a RAN may determine that a first wireless communication device (WCD) and a second WCD are contending for a resource of a preferred wireless coverage area, and that both of the WCDs are likely to be handed off to non-preferred wireless coverage area(s) if they are not granted the resource. Both WCDs may be subscribed to a home wireless service provider that also controls and/or operates the preferred wireless coverage area. The RAN may compare historical call length data of the first WCD with historical call length data of the second WCD. Based on the outcome of this comparison, the RAN may allocate the resource to the WCD that would likely incur higher roaming fees to the home wireless service provider if that WCD were to roam to a non-preferred wireless coverage area.

Abstract translation: 介绍了减轻切换到非优先无线覆盖区域的影响的方法和设备。 具体地，RAN可以确定第一无线通信设备（WCD）和第二WCD正在竞争优选的无线覆盖区域的资源，并且两个WCD都可能被切换到非优选的无线覆盖 区域，如果它们没有被授予资源。 两个WCD可以订阅也控制和/或操作优选无线覆盖区域的家庭无线服务提供商。 RAN可以将第一WCD的历史呼叫长度数据与第二WCD的历史呼叫长度数据进行比较。 根据该比较的结果，RAN可以将资源分配给WCD，如果该WCD漫游到非优选的无线覆盖区域，则可能对家庭无线服务提供商产生更高的漫游费用。

Abstract: A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

Abstract: Systems, methods, and computer-readable media for adjusting a timer mechanism based on radio frequency (RF) conditions of a network connecting source and destination devices are provided. Initially, data packets transmitted by the source device are assigned an ordering. This ordering is compared to an actual order in which the data packets are received at the destination device to ascertain whether any data packets were missing due to RF conditions. A negative response indicating missing, or lost, data packets may be returned, thereby invoking the source device to retransmit the data packets identified as missing. The device(s) may compute a probability of packet-loss (utilizing a recorded history of the transmitted packets in conjunction with the data packets actually received) and utilize the packet-loss probability to dynamically tune a time-interval of the timer mechanism. Upon expiration of the time-interval, the timer mechanism instructs the source device to retransmit the initial data packets.

Abstract: A method is disclosed for implementing an overlay carrier frequency in a wireless coverage area in response to low load in the coverage area. Normally, an carrier frequency may be added in response to high load. However, the disclosed method involves adding a carrier frequency in response to low load, as the addition of a carrier may advantageously increase the likelihood of soft handoff in certain situations, and as low load may facilitate operation on the added carrier without the need to add expensive supporting infrastructure that would typically be added to support full operation on an added carrier frequency.

Abstract: Disclosed is a method and system to help reduce the extent of roaming or use of lower priority coverage areas in a wireless communication system, by selectively managing the level of noise in a preferred coverage area. A network entity will detect that a particular coverage area has a high rate or roaming or that another coverage area (e.g., a collocated or adjacent coverage area) has a high rate of use, and the network entity will responsively reduce a noise threshold in the particular coverage area so as to then tolerate less noise in the coverage area before taking affirmative action to reduce the level of noise, and thus optimally to reduce the extent of roaming or use of less preferred coverage.

Abstract: In a communication system, a wireless access node receives an access request from a wireless communication device. In response, the access node starts an access timer and transfers signaling to the communication system indicating the access request. If the access timer expires before a response to the signaling is received, then the access node provides the wireless communication device with wireless access to the communication system. The access node receives the response to the signaling. If the response is negative and is received before the access timer expires, then the access node denies the access request. If the response is negative and is received after the access timer expires, then the access node terminates the wireless access to the communication system for the wireless communication device.

Abstract: Methods and systems provide dynamic determination of a control-channel bit rate. An access node provides service on a carrier comprising active and idle timeslots, active timeslots comprising a data channel for carrying a control channel at a bit rate that can be set to a lower value or a higher value, and traffic channels. The access node determines whether the number of active timeslots over a time period is less than a first threshold. If so, the access node sets the bit rate to the lower value. If not, the access node sets the bit rate to the higher value if at least one of the following is true: (a) control-channel occupancy exceeds a second threshold, (b) the amount of data in a traffic buffer exceeds a third threshold, and (c) control-channel occupancy exceeds a fourth threshold and the amount of data in the traffic buffer exceeds a fifth threshold.

In a particular embodiment, a method comprises wirelessly receiving a call request from a wireless communication device. In response to the call request, starting an access channel timer and transferring call set-up signaling to extend the call. If the access channel timer expires before a negative response is received to the call set-up signaling, then allocating a wireless access channel to the wireless device for the call. If the negative response is received before the timer expires, then denying the wireless access channel to the wireless device for the call. If the negative response is received after the timer expires, then releasing the wireless access channel from the wireless device. If a positive response is received before the timer expires, then allocating the wireless access channel to the wireless device for the call.

Abstract: Disclosed herein are methods and systems for sending and/or acknowledging an access probe in a radio access network. In one aspect, a method for transmitting an access probe to a radio access network, wherein time slots available to receive communications from the radio access network are defined in control-channel periods, wherein each control-channel period comprises one or more control-channel cycles, is disclosed. The method involves (a) determining a wait time until a control-channel cycle that is assigned to the access terminal; (b) making a determination as to whether or not the determined wait time is less than a predetermined maximum wait time; (c) if the determined wait time is less than the predetermined maximum wait time, then transmitting an access probe to the radio access network during the assigned control-channel cycle; and (d) otherwise, if the determined wait time is greater than the predetermined maximum wait time, then transmitting the access probe to the radio access network before the assigned control-channel cycle.
