Abstract: Multi-mode system selection (MMSS) enables a mobile station (MS) to prioritize MS preference for selecting particular radio air-interfaces (AI) across multiple standards (e.g., 3GPP, 3GPP2, WiMAX). 3GPP2 is developing a scheme MMSS-3GPP2 which is usually referred to as simply ‘MMSS.’ Other schemes exist e.g., proprietary ones (e.g., internal ePRL), an MMSS-3GPP based on the PLMN with Access Technologies of non-3GPP systems. MMSS OTASP messages and parameters are being defined in 3GPP2 to allow the carriers to provision MMSS parameters to the mobile device. With MMSS, the mobile can select and hence acquire cdma2000 and non-cdma2000 systems (e.g., LTE, WiMAX) based on carrier's preferences.

Abstract translation: 多模式系统选择（MMSS）使得移动站（MS）能够优先考虑MS偏好以跨越多个标准（例如，3GPP，3GPP2，WiMAX）选择特定无线电空中接口（AI）。 3GPP2正在开发通常简称为“MMSS”的MMSS-3GPP2方案。其他方案存在，例如专有的方案（例如，内部ePRL），基于具有非3GPP系统的接入技术的PLMN的MMSS-3GPP。 在3GPP2中定义MMSS OTASP消息和参数，以允许运营商向移动设备提供MMSS参数。 使用MMSS，移动台可以基于载波的偏好来选择并因此获取cdma2000和非cdma2000系统（例如，LTE，WiMAX）。

Abstract: Techniques to configure quality of service (QoS) and utilize radio resources for a call in a WLAN are described. In an aspect, a station ensures that an access point in the WLAN is suitable for receiving service prior to performing registration to receive services via the WLAN. In another aspect, the station first requests for radio resources for traffic flows, then requests for radio resources for signaling flows, and sends signaling as best effort traffic if radio resources are not granted for the signaling flows. In yet another aspect, the station aggregates QoS for multiple applications and requests for radio resources based on the aggregated QoS. In yet another aspect, the station releases extra radio resources corresponding to the difference between the QoS granted by the WLAN and the QoS proposed by a remote terminal for the call. In yet another aspect, the station requests for the same QoS or lower from a new access point during handoff.

Abstract translation: 描述了在WLAN中配置服务质量（QoS）和利用无线电资源进行呼叫的技术。 在一个方面，站确保WLAN中的接入点适合于在执行注册之前接收服务以经由WLAN接收服务。 在另一方面，站首先请求无线电资源用于业务流，然后请求用于信令流的无线电资源，并且如果未向信令流授予无线电资源，则将信令作为尽力流量发送。 在另一方面，站聚合基于聚合QoS的多个应用的​​QoS和对无线电资源的请求。 在另一方面，该站释放对应于由WLAN授予的QoS与针对该呼叫的远程终端提出的QoS之间的差异的额外的无线电资源。 在另一方面，站在切换期间从新的接入点请求相同的QoS或更低的QoS。

Abstract: A wireless communications device is configured to establish a radio level session with a network at a relatively high or highest protocol level among a plurality of protocol levels supported. Upon failures in establishing, or during, a network level data session, the radio level session is closed. Thereafter, the device re-attempts to establish the network level session at a lower, fallback protocol level, by pretending it is a legacy device incapable of supporting the high protocol level. In this manner, the network is likely to follow a different procedure in establishing data communications, whereby an error that caused the failure is less likely to be repeated. As examples, error conditions in eHRPD data sessions result in fallback to HRPD or 1xRTT data sessions. A network based alternative embodiment implements protocol fallback via appropriate fallback instructions to the wireless device.

Abstract translation: 无线通信设备被配置为在所支持的多个协议级别中的相对较高或最高协议级别与网络建立无线电级会话。 在建立或在网络级数据会话期间发生故障时，关闭无线电级别会话。 此后，设备重新尝试以较低的回退协议级别建立网络级会话，假设它是不能支持高协议级别的传统设备。 以这种方式，网络可能遵循建立数据通信的不同过程，由此导致故障的错误不太可能被重复。 作为示例，eHRPD数据会话中的错误条件导致HRPD或1xRTT数据会话的回退。 基于网络的替代实施例通过适当的回退指令实现到无线设备的协议回退。

Abstract: 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.

Abstract: Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.

Abstract: 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.

Abstract: Aspects disclosed herein relate to avoiding a better system reselection (BSR) procedure when no 3GPP (e.g., LTE based) network is available. In one example, a network entity may be equipped to determine that a geographic region (GEO) includes one or more cells that provide 3GPP coverage, and provision multi-mode system selection (MMSS) files to distinguish the GEO than includes one or more cells that support 3GPP coverage from one or more GEOs that do not include 3GPP coverage. Further, a user equipment (UE) may be equipped to detect initiation of a BSR procedure for a multimode UE currently being served by a 3GPP2 based network, and determine whether to scan for a 3GPP based network based on one or more MMSS files.

Abstract: Techniques to detect for end of service using dynamic inactivity timer thresholds are described. An access terminal establishes a radio connection for one or more applications. Data and signaling for the application(s) may be sent on one or more first flows (e.g., RLP flows) that may carry any number of second flows (e.g., IP flows). The access terminal determines a dynamic inactivity timer threshold for each first flow, e.g., based on at least one inactivity timer threshold for at least one second flow mapped to that first flow. The access terminal determines whether each first flow is inactive based on the inactivity timer threshold for that first flow, e.g., declares each first flow to be inactive if no activity is detected on that first flow for a period exceeding the inactivity timer threshold. The access terminal closes the radio connection when all first flow(s) are determined to be inactive.

Abstract translation: 描述使用动态不活动定时器阈值检测服务结束的技术。 接入终端为一个或多个应用建立无线电连接。 用于应用的数据和信令可以在可携带任何数量的第二流（例如，IP流）的一个或多个第一流（例如，RLP流）上发送。 接入终端例如基于映射到该第一流的至少一个第二流的至少一个不活动定时器阈值来确定每个第一流的动态不活动定时器阈值。 接入终端基于该第一流的不活动定时器阈值来确定每个第一流是否不活动，例如，如果在超过非活动定时器阈值的时间段内在该第一流上没有检测到活动，则将每个第一流声明为不活动。 当所有第一流被确定为不活动时，接入终端关闭无线电连接。

Abstract: 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.
