Abstract: Methods and apparatus for dynamic search management in a multi-mode device. In one embodiment, a mobile device performs network search and acquisition by dynamically changing search delays and/or search frequencies. In one implementation, the mobile device adjusts the amount of time allocated for each network search based on e.g., previous network connection history (e.g., previously connected to a home network, previously connected to a roaming network), device conditions, user preferences, geographical information, etc. By focusing search effort on cellular technologies which have a high likelihood of success, the mobile device can greatly improve search time and reduce unnecessary power consumption.

Abstract: A method for negotiating a session personality based at least in part on a roaming agreement is provided. The method can include a roaming access network receiving an identifier provided by an access terminal attendant to establishment of a session between the access terminal and the roaming access network. The method can further include the roaming access network using the identifier to determine a home network associated with the access terminal. The method can additionally include the roaming access network determining one or more radio access technology (RAT) versions covered by a roaming agreement between the home network and the roaming access network. The method can also include the roaming access network negotiating a session personality for use in the session based at least in part on the one or more RAT versions covered by the roaming agreement.

Abstract: Methods and apparatuses to adaptively select radio frequency channels with which to connect a mobile wireless device to a wireless network are described. In response to a trigger event, the mobile wireless device selects a radio frequency channel from a list of radio frequency channels that use a first radio access technology and transmits a series of connection requests on the selected radio frequency channel. When no acknowledgement is received, the mobile wireless device excludes the selected radio frequency channel from the list of radio frequency channels and repeats the selecting, transmitting and excluding steps up to a maximum number of repetitions before attempting to connect to the wireless network using a second radio access technology.

Abstract: Methods, apparatuses and computer readable media are described to compensate for radio frequency link imbalances in a wireless communication device. Processing circuitry in the wireless communication device detects a radio frequency link imbalance for a bi-directional communication link. The wireless communication device biases one or more operational parameters of the wireless communication device to adjust for a performance degradation induced by the radio frequency link imbalance. The wireless communication device determines whether a trigger condition for cell selection, reselection, or handover occurs based on the biased operational parameters, and when the trigger condition occurs, performs a remediating action to compensate for the radio frequency link imbalance. Remediation can include performing an intra-RAT or inter-RAT reselection or handover.

Abstract: A method for reducing packet loss during data transfer from a network to a wireless communication device over a connection is disclosed. The method can include the wireless communication device signaling a first receive window size for a data transfer; determining occurrence of an event resulting in an interruption of the connection; and, in response to determining occurrence of the event, signaling a second receive window size for the data transfer prior to the event to trigger an adjustment of a data rate of the data transfer in preparation for the event.
