Abstract: Methods and apparatus are provided for operating in a first RAN at a working frequency, determining a priority of measurement tasks enabled by the first RAN, and dynamically scheduling the tasks according to the priority. For certain aspects, the first RAN may be a TD-SCDMA network. The measurement tasks are intended to measure at least one parameter of a serving cell in the first RAN on a primary frequency, at least one cell in the first RAN on at least one frequency other than the primary frequency, one or more cells in at least one RAN other than the first RAN (e.g., a GSM network) or any combination thereof. This dynamic assignment allows the UE to make scheduling decisions on which frequencies and RANs to measure, as well as how often these frequencies and RANs are measured, thereby providing for more efficient use of idle slots over conventional haphazard scheduling.

Abstract translation: 提供了以工作频率在第一RAN中操作的方法和装置，确定由第一RAN启用的测量任务的优先级，并根据优先级动态地调度任务。 对于某些方面，第一RAN可以是TD-SCDMA网络。 测量任务旨在测量主频率上的第一RAN中的服务小区的至少一个参数，在主频率以外的至少一个频率上的第一RAN中的至少一个小区，至少至少一个或多个小区 除了第一RAN之外的一个RAN（例如，GSM网络）或其任何组合。 该动态分配允许UE对要测量的哪些频率和RAN进行调度决定，以及测量这些频率和RAN的频率，从而提供比常规随机调度更有效地利用空闲时隙。

Abstract: Certain embodiments allow security keys to be maintained across mobile device states, or communication events, such as hand-over, and system idle and sleep power savings modes. By monitoring the lifetime of security keys, keys may be refreshed in an effort to ensure key lifetimes will not expire during a hand-over process or other device unavailable state.

Abstract: Certain embodiments of the present disclosure present methods and apparatuses that enable a mobile station (MS) to selectively reject downlink (DL) data during idle mode. The MS may determine whether to reject the pending DL data based on information about the data. This information may be provided by a base station (BS) that is part of the access service network (ASN) that is retaining the DL data. The information provided by the BS may, for instance, include service flow information related to the pending DL data. In certain embodiments, the information may include one or more internet protocol (IP) packets that are part of the pending DL data.

Abstract translation: 本公开的某些实施例提供使移动站（MS）在空闲模式期间选择性地拒绝下行链路（DL）数据的方法和装置。 MS可以基于关于数据的信息来确定是否拒绝待决的DL数据。 该信息可以由作为保留DL数据的接入服务网络（ASN）的一部分的基站（BS）提供。 例如，BS提供的信息可以包括与未决DL数据相关的服务流信息。 在某些实施例中，信息可以包括作为未决DL数据的一部分的一个或多个因特网协议（IP）分组。

Abstract: Methods and apparatus for re-acquiring a WiMAX network after a relatively long power saving mode (e.g., sleep or idle mode) using a “pre-wakeup” scheme are provided. According to this pre-wakeup scheme, a mobile station (MS) may power up receiving circuitry to search for the current channel or, if unsuccessful, a neighbor channel. After a successful network search during sleep mode, the MS may return to sleep for the remainder of the sleep window until the circuitry is powered up a second time to wakeup and then listen for an expected message. By pre-waking up and searching before waking up for the expected message, the MS may counteract the effects of the potential error in the local oscillator frequency accumulated during the long sleep mode. In this manner, the message miss rate may be reduced, thereby saving power and extending the time in which the MS may operate between battery rechargings.

Abstract translation: 提供了在使用“预先唤醒”方案的相对长的省电模式（例如，睡眠或空闲模式）之后重新获取WiMAX网络的方法和装置。 根据该预先唤醒方案，移动台（MS）可以为接收电路供电以搜索当前信道，或者如果不成功，则邻居信道。 在休眠模式下成功进行网络搜索后，MS可以在睡眠窗口的其余部分返回休眠状态，直到电路第二次上电并唤醒预期消息。 在唤醒预期消息之前，通过预醒和搜索，MS可以抵消在长睡眠模式期间累积的本地振荡器频率中的潜在误差的影响。 以这种方式，可以减少消息丢失率，从而节省电力并延长MS可以在电池充电之间操作的时间。

Abstract: A method for frame number synchronization in a wireless communication network may be implemented by a base station. The method may include determining a current time from a timing source that is common to multiple other base stations. The method may also include determining a time offset between the current time and a reference time, wherein the base station and the multiple other base stations use the same reference time for determining the time offset. The method may also include determining a current frame number based on the time offset.
