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.

摘要： Methods and apparatuses are provided that include enhancing decoding of multicast broadcast control communications, which can be of a relatively large size. A configuration message related to a broadcast channel structure can be received in multiple instances and/or segmented data units. A receiver can combine multiple instances and/or accumulate segmented data units to obtain and/or decode a control channel over which the configuration message is communicated. Communicating segmented data units of the configuration message can allow a broadcast station to utilize a lower data rate, more reliable modulation and coding scheme to encode the configuration message.

摘要： The described aspects include methods and apparatus for aligning a voice over data vocoder timing at a user equipment (UE). A scheduling interval timing is determined at the UE, and a timing of a vocoder of the UE can be aligned based on the scheduling interval timing. The UE transmits one or more packets generated by the vocoder according to the timing in at least one transmission period related to the scheduling interval timing. Thus, time delay between packet generation and transmission can be minimized.

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： When a user equipment engaged in mobile communications transfers from a network with one radio access technology (RAT) to another network with a different radio access technology, maintaining continuity of location based services can improve system performance. A user equipment may perform a series of checks when undergoing inter-RAT transfer to determine if a location based services protocol used with the source network is operable on the target network. The UE also determines if location based services sessions are at a point where they can be continued following inter-RAT transfer. Where possible, protocols and sessions are maintained to preserve location based services continuity.

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 facilitating higher priority radio access technology (RAT) search and cell reselection in areas having a plurality of overlapping RATs, such as GSM and LTE. According to certain aspects, a user equipment (UE) may generate a local set of cell reselection parameters based on one or more default cell reselection parameters and/or stored system information received during previous connects with found cells. According to certain aspects, the UE may perform cell reselection based on the local set of cell reselection parameters.

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.

摘要： Techniques for deriving message counts based at least in part on a locally stored message count and at least a portion of a message count received from a remote network node are disclosed. The message counts can relate to downlink (DL) non-access stratum (NAS) counts. In one aspect, a device can receive a number of least significant bits of the DL NAS count in a handover message. The device can derive a DL NAS count by utilizing a remaining portion of most significant bits of a locally stored DL NAS count, and can determine whether to increment or decrement the most significant bits based at least in part on a parameter to handle cases where the least significant bits of the locally stored DL NAS count have wrapped due to overflow and/or underflow.
