摘要： Controller and method for Handover (HO) based 1×CSFB communicates Calling Party Number (CPN) to User Equipment (UE) a in a cellular communication system. A first solution provides Interworking Solution (IWS) adding CPN sent to target Base Station Controller (BSC) via Mobile Switching Center (MSC) in Interoperability Specification (IOS) HO messages. A second solution provides that IWS sends CPN with Air Interface HO message and stores the CPN until UE transition to the target Radio Access Network and acquires a traffic channel. A third solution provides that IWS receives CPN from MSC with a paging message and stores the CPN until UE transition to the target Radio Access Network and acquires a traffic channel. A fourth solution provides sending AWI message to the target Radio Access Network from the MSC. A fifth solution provides that IWS sends CPN via Feature Notification Message (FNM) data tunneled to UE before the paging message to let user decide whether to accept a call before leaving 3G/4G cellular communication.

摘要： Systems and methodologies are described that facilitate improved multi-mode system selection in a wireless communication system. As described herein, various techniques can be utilized to synthesize system databases corresponding to disparate groups of radio access technologies (RATs), such as a Public Land Mobile Network (PLMN) list and/or a Preferred Roaming List (PRL), with one or more overlay databases and associated location information to generate a multi-mode list of preferred systems. As described herein, a preferred system listing can be constructed to leverage fine granularity of information in one or more databases while still supporting databases with coarser information. Techniques are additionally described herein for augmenting and/or grouping one or more overlay databases to facilitate a higher available granularity of information for various RATs than that provided in system databases corresponding to the RATs. Techniques are additionally provided for automated generation of preferred system listing based on changes to observed location.

摘要： Certain aspects of the present disclosure propose methods and apparatuses for reducing power consumption associated with performing reselection between radio access technologies (RATs). For example, a network that supports first and second RATs may obtain a list of neighbor base stations of a third RAT and determine whether to transmit the neighbor list on the first RAT, the second RAT, or both. In another aspect, a user equipment (UE) may combine information from the neighbor lists received from the first and the second RATs, and decide whether to take measurements in the third RAT based on the combined information. The UE may also maintain a central entity with measurements taken in the third RAT based on the neighbor lists received from the first and the second RATs and decide whether to perform cell reselection based on measurements in the central entity.

摘要： Methods and apparatuses are provided that facilitate receiving signals from one or more base stations while communicating with a serving base station. Devices can receive the signals in autonomous gaps, during which the device can tune away to receive the signals. A device can report a low channel quality indicator (CQI) value to the serving base station prior to the autonomous gap to decrease a likelihood that the base station will schedule transmissions to the device, or at least decrease a data rate for transmissions. In another example, the device can report a CQI reserved for indicating starting an autonomous gap. In either case, the described methods and apparatuses can minimize data loss during the autonomous gap. Once the device returns from receiving the signals, the device can report an improved or actual CQI value to the base station to resume communications.

摘要： Pre-registration involves establishing and maintaining the same Packet Data Network (PDN)/Quality of Service (QoS) context that exists in a 3GPP Long Term Evolution (LTE) network via a data tunnel in a 3GPP2 evolved High Rate Packet Data (eHRPD) network. To avoid undue increases in the traffic on a LTE Air Interface and core network, optimizations selectively complete the PDN context only for a subset of the PDN connections, only when close to performing a handover, or other trigger conditions.

摘要： Motion status states reported by an advanced motion detection process or other means of obtaining a movement state of Stationary or Non-Stationary from filtered accelerometer data are utilized to reacquire service during Out of Service scenarios. Both movement states operate in three power phases: aggressive scanning or normal power mode, slow scanning or moderate power mode, and deep sleep or power saving mode. The scanning rate, power mode, scanning period and/or channel list depend upon the movement state and power phase. Motion information obtained from an advanced motion detection process provides substantial improvements in service reacquisition performance and power consumption in stationary Out of Service scenarios. When compared to traditional service reacquisition scanning routines, the reductions in average current can be achieved of: at a 5-minute OOS mark, ˜45% reduction, at a 15-minute OOS mark, ˜60% reduction and at a 6-hour OOS mark, ˜50% reduction.

摘要翻译： 通过高级运动检测过程报告的运动状态状态或从滤波的加速度计数据获得静止或非固定运动状态的其他方法被用于在停止服务情景期间重新获取服务。 两种移动状态都在三个功率阶段运行：积极扫描或正常功率模式，慢速扫描或中等功率模式，以及深度睡眠或省电模式。 扫描速率，功率模式，扫描周期和/或通道列表取决于移动状态和功率相位。 从高级运动检测过程获得的运动信息在固定的停止服务场景中提供了服务重新获取性能和功耗的实质性改进。 与传统的服务回收扫描程序相比，平均电流的降低可以实现：在5分钟的OOS标记，减少约45％，15分钟的OOS标记，约60％的减少和6小时 OOS标记，减少约50％。

摘要： A method and apparatus for world-mode devices capable of managing technology selection for multimode roaming between existing access technologies, as well as possible future access technologies, in a manner that eliminates wasteful scanning for non-existent systems and reduces roaming charges is disclosed. The method allows the device an opportunity to reacquire its home system before scanning for available roaming network resources in a prioritized manner that mitigates roaming costs, while conserving power and acquisition delays by eliminating scanning for non-existent system types. A minimum OOS duration is imposed on a home system before acquisition of a roaming partner to provide more time to re-acquire the home system. Preferred partner scanning and acquisition reduces roaming charges, while scanning for non existent systems is eliminated altogether.
