Abstract: A method and apparatus for packet data service discovery are described. A current blacklist comprising entries for wireless networks not providing packet data services (i.e. either not supporting the services or not having a packet data services roaming agreement) is kept in memory of the mobile device based on previous attempts to connect to such networks. Current preferred roaming lists identify whether a given wireless network can be acquired, but do not identify whether a data services roaming agreement exists. At least one of the following advantages is provided: no advance knowledge of data services roaming agreements is required; no mobile device software change is required when the data services roaming agreement changes; mobile device can notify a server of a wireless network status change; significant power savings at the mobile device; and avoid unnecessary network access, which in turn saves network resources and capacity.

Abstract: Method, and associated apparatus, for operating a hybrid access terminal operable in a CDMA 1x/EVDO hybrid communication session system. The hybrid access terminal is operable to communicate pursuant to an EVDO communication session and to a PPP communication session. The opening and closing of the communication sessions are independent of one another. Opening of one session does not require opening of another of the sessions. And, closing of one of the sessions does not require closing of the other of the sessions.

Abstract: An apparatus and method is provided for making use of black-list network information to make scanning more efficient in multi-mode mobile devices. When performing a scan for a network, if a network that is blacklisted is found, scanning is discontinued for any network that has the same radio access technology as the network that was found. Thus, excessive scanning that can be costly for the mobile device in terms of battery life and responsiveness to provide service, is avoided.

Abstract: Generally, the present invention provides a method for detecting poor RF conditions, and entering different sleep mode levels or phases in accordance with the RF conditions to save battery power. Mobile device battery life can be conserved when the mobile device detects poor RF conditions and enters a deep sleep mode of operation. In this deep sleep mode of operation the mobile device periodically samples the RF conditions and gradually increases the period between samples when the RF conditions do not improve. Because mobility can change the RF condition for wireless devices even in areas of good RF coverage, the mobile device operating in the deep sleep mode can detect this mobility and thus enhance the probability of entering an idle state, or alternatively, entering a longer power save mode. When the RF condition improves, the mobile device exits from the deep sleep mode and returns to the idle state.

Abstract translation: 通常，本发明提供了一种用于检测不良RF状况的方法，并根据RF条件进入不同的睡眠模式级别或阶段以节省电池电量。 当移动设备检测到差的RF条件并进入深度睡眠操作模式时，可以节省移动设备的电池寿命。 在这种深度睡眠操作模式中，当RF条件不改善时，移动设备周期性地对RF条件进行采样并逐渐增加样本之间的周期。 因为即使在良好的射频覆盖区域中，移动性也可以改变无线设备的射频条件，所以在深度睡眠模式下工作的移动设备可以检测这种移动性，从而提高进入空闲状态的可能性，或者替换地，进入更长的功率节省 模式。 当RF条件改善时，移动设备退出深度睡眠模式并返回到空闲状态。
