摘要： A method to manage a call in a communication system and an access node of the communication system are disclosed. The method includes receiving, by the communication system, a call request for a voice call from a first device to communicate with a second device, wherein the second device is a subscriber of the communication system, and transmitting, by the communication system to the first device, a first message comprising an indication that the second device is operating in a text message-only mode, when the second device is roaming and a roaming usage of the second device meets a roaming criteria. The access node may be configured to transmit to the first device the first message, when the first device requests to establish a call with the second device through the access node, the second device is roaming, and a roaming usage of the second device meets the roaming criteria.

摘要： A wireless communication device determines a latitude indicator, longitude indicator, and received signal strength for its current location. The devices processes the latitude indicator, longitude indicator, and received signal strength to estimate its elevation at the location. The device also processes its handover history to determine a handover probability factor. The device then processes the estimated elevation and handover probability factor to estimate if the device is located in a building above an elevation level. If the estimate indicates that the device is located within the building above the elevation level, then the device modifies a handover parameter to inhibit handover attempts.

摘要： A wireless communication device (WCD) may be able to acquire wireless service from preferred wireless coverage areas that are managed by the WCD's service provider. In some cases, the WCD may instead use wireless service from non-preferred wireless coverage areas of the service provider's roaming partners. In order to save roaming fees, the service provider's RAN may determine when the WCD is likely to roam to a non-preferred wireless coverage area. In response to this determination, the RAN may transmit a redirect message to the WCD, causing the WCD to switch from one preferred wireless coverage area to another preferred wireless coverage area. In some situations, the RAN may transmit such a redirect message because the WCD has reported that it has a low remaining battery life.

摘要： A method and system is disclosed for dynamic adjustment of auxiliary pilot triggering based on latency. In an example embodiment, an AT that engages in a data communication that requires low latency will transmit its auxiliary pilot unconditionally and without regard to the payload sizes of the packets it transmits. Thus, the AT will not use a comparison of payload packet size with a threshold packet size when determining whether to transmit its auxiliary pilot. Rather, the AT will begin transmitting its auxiliary pilot upon a determination that it is engaged or will engage or has begun to engage in a communication that requires low latency. At the same time, an AT that engages in data communication that does not require low latency will advantageously trigger its auxiliary pilot less aggressively in response to an instruction from the base station to do so.

摘要： Air interface protocols under the numerous wireless communication standards allow use of a quick-paging channel (QPCH) to expedite paging and call setup. When a hybrid mobile device is engaged in wireless communications under a first air interface protocol, it may periodically switch over to a second air interface protocol to check for pages on the slower standard paging channel (PCH). To increase throughput under the first air interface protocol, it would be useful to employ the QPCH under the second air interface protocol, to reduce time spent by hybrid device checking for pages under the second air interface protocol. However, the QPCH uses resources under the second air interface protocol, so it would be best to not have the QPCH activated at all times. According to the invention, the system would activate the QPCH under the second air interface protocol in response to there being more than an upper threshold number of hybrid devices active under the first air interface protocol. In turn, the system may deactivate the QPCH under the second air interface protocol in response to there being some lower threshold number of hybrid devices active under the first air interface protocol.

摘要： A method and system is disclosed for intelligent power control in a wireless communication system. In accordance with an example embodiment, a first device will operate in a dynamic-power state in which it transmits a power-increment command or power-decrement command in response to each of periodic comparisons of a signal power level of a signal received from a second device with a threshold power level. While operating in the dynamic-power state, the first device will recognize when it has transmitted a threshold number of alternating power-increment and power-decrement commands, and responsively will transition to operating in a steady-power state in which it continues to transmit alternating power-increment and power-decrement commands even if it detects that the second device has ceased responding to the alternating power-increment and power-decrement commands. While operating in the steady-power state, the first device will recognize when the difference between a currently-received signal power level and the threshold power level is greater than a differential threshold power, and based at least on the recognition will transition to operating in the dynamic power state.
