Abstract: A communications network may be used to convey Short Message Service (SMS) messages using the Internet Protocol (IP). User equipment may transmit an SMS-over-IP Session Initiation Protocol (SIP) message to wireless equipment over a high-bandwidth communications link. The wireless equipment may route the SMS-over-IP SIP message to the ePDG. When the high-bandwidth link is unavailable, the user equipment may transmit a compressed message to the proxy server over a low-bandwidth communications link. The proxy server may convert the compressed message into an SMS-over-IP SIP message that is transmitted to the ePDG. The proxy server may serve as a proxy for the first user equipment from the perspective of the ePDG. This may allow SMS message data to continue to be conveyed through the communications network even when the high-bandwidth communications link becomes unavailable.

Abstract: Apparatus, system, and method for notifying a mobile station of an incoming circuit switched call during a packet switched session. During the packet switched session, a mobile station may receive a call notification of the circuit switched call. The call notification may be received via a packet switched network associated with the packet switched session. Additionally, the call notification may identify a calling party. In response, an indication of the circuit switched call may be displayed to a user on a display of the mobile station. This indication of the circuit switched call may identify the calling party. Additionally, the indication may be displayed while maintaining the packet switched session. In response, the user may provide input to the mobile station regarding whether to accept the circuit switched call. Based on this input, the mobile station may accept or reject the circuit switched call.

Abstract: This disclosure relates to caching SIM files at a baseband processor to reduce cellular bootup time. According to one embodiment, a wireless device may read SIM files from a SIM and store a local copy of each file in a cache of the baseband processor of the wireless device. SIM identification information for the SIM from which the cached files were read may be associated with the cache. Indicator information usable for comparing file versions may also be generated and stored in the cache for each file. Upon a subsequent SIM initialization, the wireless device may read SIM files from the cache instead of from the initialized SIM if the cached version is identical to the SIM version, which may be determined based at least in part on the SIM identification information and the indicator information for such files.
Abstract translation: 本公开涉及在基带处理器上缓存SIM文件以减少蜂窝启动时间。 根据一个实施例，无线设备可以从SIM读取SIM文件，并将每个文件的本地副本存储在无线设备的基带处理器的高速缓存中。 读取缓存文件的SIM卡的SIM识别信息可以与缓存相关联。 用于比较文件版本的指示符信息也可以被生成并存储在每个文件的高速缓存中。 在随后的SIM初始化中，如果缓存版本与SIM版本相同，则无线设备可以从高速缓存而不是从初始化的SIM读取SIM文件，其可以至少部分地基于SIM识别信息和指示符来确定 这些文件的信息。

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: Methods and apparatus for client-based capabilities management for e.g., heterogeneous networks. In one exemplary embodiment, a client device associated with a cellular (e.g., EV-DO) network attempts to negotiate a session with a visited network while roaming. The negotiated session is selected from only the set of available capabilities (only the personalities which have a roaming agreement between the home network and the visited network), to ensure that the session negotiation can complete successfully. Once the session is negotiated, the visited network can execute standard authentication and authorization procedures with the assistance of the home network.

Abstract: Determining whether to operate in a single radio access technology (RAT) mode or a dual RAT mode for a user equipment (UE) having a radio capable of communicating using at least a first RAT and a second RAT. The UE may determine whether current path loss for the first RAT exceeds a maximum path loss. Based on the results of determining whether the current path loss for the first RAT exceeds the maximum path loss, the UE may determine whether to operate in the single RAT mode or the dual RAT mode. Accordingly, based on this determination, the UE may operate in the single RAT mode or the dual RAT mode based on the determination.

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: This application describes systems and processes for beam selection performance refinement in static conditions of wireless devices (e.g., user equipment UE). A data processing system of the UE is configured to perform a beam scan for testing multiple high gain candidate beams on a physical downlink shared channel (PDSCH) and link adaptation (LA) channel state information reference signal (LA-CSI-RS) while the UE is not moving and the data processing system of the UE determines that the channel is stable. The data processing system is configured to refine a given beam choice based on a determined capacity of the beams (e.g., from PDSCH signaling and/or LA-CSI-RS signals) to optimize data throughput.
