摘要： Devices and methods are provided for optimizing the timing of multi-mode system scans in a wireless communication environment. In one embodiment, the method may involve determining at least one of location and movement of a mobile entity (ME). The method may involve adjusting a timer between preferred system scans based on the at least one of the location and the movement of the ME. For example, determining may involve utilizing a movement sensor (e.g., an accelerometer and/or a voltage-controlled oscillator accumulator) to detect the movement of the ME, and/or receiving signals from a Global Positioning System or the like.

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： A unified approach multi-mode system selection is provided for a mobile device implementing multiple multi-mode system selection (MMSS). Different system operators may provide their own MMSS databases and rules in different frameworks. To allow a mobile device to perform MMSS without modifying its software, the different databases may be mapped into a common database. In one example, an MMSS solution is implemented that uses a Preferred Roaming List (PRL) database according to a 3GPP2 system selection to specify the prioritization of 3GPP and 3GPP2 systems the mobile device. When the mobile device is powered up, the information in the different MMSS databases is mapped into a common database (“PRL with PLMN records”). The wireless communication device then acts on this information in the common database to perform system selection.

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： Devices and methods are provided for facilitating handing over to a hybrid femto access point that implements multiple radio access technologies (RATs), including a first RAT and a second RAT. In one embodiment, the method involves detecting a pilot from the hybrid femto access point, wherein the pilot is associated with the first RAT. The method involves registering with the hybrid femto access point on a first channel associated with the first RAT based upon the detected pilot. A system selection database is analyzed to identify a second channel associated with the second RAT, and a selection to handover to the identified second channel is effectuated.

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： A base station in a wireless communication network multi-codes a shared packet data channel using a continually changing set of spreading codes, and dynamically updates the transmission frequency of messages identifying the spreading codes to be used for that multi-coding based on tracking the net gain in data throughput for the shared channel that is obtained by transmitting such messages. In a 1xEV-DV network context, for example, a Walsh code in the defined Walsh code space that is not contiguous with the Walsh codes currently allocated to multi-coding the 1xEV-DV Forward Packet Data Channel (F-PDCH) generally remains unavailable for such use until an updated Walsh Mask Broadcast (WMB) message is transmitted to the mobile stations being served on the F-PDCH. The base station thus is configured to determine the frequency at which to send such messages and thereby make the unavailable codes available for multi-coding use.
