摘要： Circuit-switched fallback (CSFB) is a technique to deliver voice-services to a mobile, when the mobile is camped in a long-term evolution (LTE) network. This may be required when the LTE network does not support voice services natively. If a user makes a mobile originating (MO) call, or receives a mobile terminating (MT) call, the UE may inform the LTE network that the UE is leaving for the call by initiating a call setup procedure. However, there may be instances where the call setup procedure may fail. If the call setup procedure was either not initiated, or was initiated but failed, the UE may determine to search for a suitable CS RAT/cell on its own without instructions/commands from the network. Therefore, certain aspects of the present disclosure provide techniques for the UE to find CS services based on information collected at the UE.

摘要： Methods and apparatus are provided for device configuration (e.g., feature segment loading and system selection). Certain aspects of the present disclosure generally relate to operating a user equipment (UE) in a first radio access network (RAN) with a first set of modem features that supports the first RAN, detecting a second RAN not supported by the first set of modem features, and rebooting the modem software to load a second set of modem features that supports the detected RAN. For certain aspects, the first RAN may be a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network and the second RAN may be a Wideband-Code Division Multiple Access (W-CDMA) network or long term evolution network. This allows features to be loaded into memory (e.g., only) when they are required to support a detected RAN, rather than loading an entire image, thereby conserving DRAM and increasing efficiency.

摘要： Techniques are provided for controlling downlink data transfer during carrier aggregation. For example, a method may control a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation. The method may include detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection. The method may include, in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.

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 disclosure relate generally to search of radio access technologies (RAT). For example, certain aspects of the present disclosure relate to a technique for performing higher priority radio access technology (RAT) searches in areas having a plurality of overlapping RATs, such as Global System for Mobile communications (GSM) and Long Term Evolution (LTE). According to certain aspects, a user equipment (UE) may be configured to periodically search for higher priority RATs in neighboring cells. According to certain aspects, upon finding a higher priority RAT cell, the UE may be further configured to evaluate, or “pre-evaluate”, criteria for cell reselection from found cell to the currently camped cell, while still camped on the current cell. The UE may be configured to decide whether or not to switch to the found cell based on the evaluation.

摘要： A method is provided for facilitating preservation of session context information during an inter-radio access technology service retry. A user equipment (UE) may initiate a data transmission for a first service over a wireless communication session with a first network. Upon ascertaining that the first service has failed over the first network, a failover procedure is initiated by sending a service request for a second service to the first network. The second service may be distinct from the first service and has the effect of suspending the wireless communication session with the first network. The UE then resends the data transmission for the first service over a second network. The UE then resumes use of the wireless communication session over the first network after resending the data transmission over the second network. This resumption is done by using context information for the wireless communication session preserved prior to the suspension.
