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： A heterogeneous communication system enables femto Access Points (APs) to advertise handoff related information on a first Radio Access Technology (RAT), such as for receipt by a multi mode mobile device (e.g., a mobile device capable of operation on a plurality of RATs), wherein the handoff related information permits the multi mode mobile device to identify the femto access point on a second RAT. The multi mode mobile device can be connected to a macro node (e.g., a macro base station, an evolved Base Node, etc.) using the first RAT via a Wireless Wide Area Network (WWAN) air-interface (e.g., 1×, HRPD, eHRPD), while independently reading/decoding overhead messages on the second RAT for connection thereto (e.g., connection to the femto access point on the second RAT.) The second RAT can be another WWAN, a Wireless Local Access Network (WLAN) or a Personal Access Network.

摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：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。

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： 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.

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.
