摘要： Devices and methods are provided for optimizing the timing of multi-mode system scans in a wireless communication environment. In one embodiment, the method may involve determining at least one of location and movement of a mobile entity (ME). The method may involve adjusting a timer between preferred system scans based on the at least one of the location and the movement of the ME. For example, determining may involve utilizing a movement sensor (e.g., an accelerometer and/or a voltage-controlled oscillator accumulator) to detect the movement of the ME, and/or receiving signals from a Global Positioning System or the like.

摘要： A unified approach multi-mode system selection is provided for a mobile device implementing multiple multi-mode system selection (MMSS). Different system operators may provide their own MMSS databases and rules in different frameworks. To allow a mobile device to perform MMSS without modifying its software, the different databases may be mapped into a common database. In one example, an MMSS solution is implemented that uses a Preferred Roaming List (PRL) database according to a 3GPP2 system selection to specify the prioritization of 3GPP and 3GPP2 systems the mobile device. When the mobile device is powered up, the information in the different MMSS databases is mapped into a common database (“PRL with PLMN records”). The wireless communication device then acts on this information in the common database to perform system selection.

摘要： Systems and methodologies are described herein that facilitate data session suspend control in a multi-radio wireless communication system based on user equipment capability. As described herein, various techniques are provided herein whereby a wireless communication network with which a user device communicates can suspend a data session and/or other communication session associated with the user device upon identifying that the user device has moved to a disparate communication network based on the transmitter/receiver capabilities of the user device. In one example herein, a mobility management entity and/or other network management entity can determine whether to perform suspend control based on an event notification from another network based on user capability. In another example herein, a network to which a user device moves can determine whether to send an event notification to another network associated with the user device based on capabilities of the user device.

摘要： Devices and methods are provided for system selection from a plurality of wireless system access technologies, such as a first group (e.g., 3GPP2 technologies) and a second group (e.g., 3GPP technologies). In one embodiment, the method may involve storing identification information pertaining to the first group in a database, wherein the database may concern the priority of ones of the access technologies pertaining to the second group. The method may also involve selecting a preferred access technology from one of the first and second groups based at least in part on the identification information stored in the database.

摘要： Certain aspects of the present disclosure propose a method for domain selection in a multimode UE. The domain selection method may be used to select domains for short message service (SMS) and/or voice service when the UE has camped on a packet switched (PS) network such as LTE. The proposed domain selection method may take into account UE capabilities, home operator preferences, visited operator preferences, visited network capabilities, and user settings.

摘要： Certain aspects of the present disclosure relate to techniques for improving a circuit-switched fallback (CSFB) user experience. In aspects, methods and systems for autonomously returning a user equipment (UE) from a 2G (2nd generation)/3G (3rd generation) network to an LTE (Long Term Evolution) network are provided. The UE may store a flag to note whether a current circuit switched (CS) call in the 2G/3G network is a result of a CSFB. The UE, in response to detecting a termination of the current CS call in the 2G/3G network and determining that the terminated call was a CSFB call (e.g., from the status of the flag), may trigger a mobility mechanism to autonomously return the UE to the LTE network.

摘要： Certain aspects of the present disclosure relate to wireless communications and methods and apparatus for downlink flow control at a user equipment (UE). Aspects generally include monitoring, by a UE, one or more parameters related to the UE, and selectively dropping received packets based on the one or more parameters in order to trigger a rate control mechanism. Selectively dropping received packets may occur at a Packet Data Convergence Protocol (PDCP) layer in order to reduce a corresponding transmission control protocol (TCP) throughput. Accordingly, packets may be selectively dropped prior to reaching an applications processor.
