Abstract: The application relates to Inter-Radio Access handover. A typical user equipment UE in CONNECTED mode in an earlier-technology network, such as a 2G or 3G network, lacks an autonomous mechanism for returning to a later-technology network, such as 4G or later, after the end of a coverage hole. Without the proposed method, the UE would remain connected to the earlier-technology network even though the UE has exited the later-technology network coverage hole. This problem is solved in that, once a data session, that commenced in the later-technology network (614), has been handed over to the earlier- technology network (618), begins autonomously to measure the later- technology network in an attempt to return to this network as soon as possible (620). Once this measurements indicate that the later- technology network is once again available, the handover procedure to the later-technology network is triggered (628, 630, 634).

Abstract translation: 本申请涉及无线电接入切换。 在诸如2G或3G网络的早期技术网络中，在CONNECTED模式中的典型用户设备UE在覆盖孔结束之后缺少返回到稍后技术网络（例如4G或更迟）的自主机制。 没有所提出的方法，即使UE已经退出了后期技术网络覆盖孔，UE也将保持连接到早期技术网络。 这个问题的解决是，一旦在后期技术网络（614）中开始的数据会话已被交给早期技术网络（618），则自主地开始测试后续技术网络 尽快回到这个网络（620）。 一旦这种测量表明后期技术网络再次可用，触发到后期技术网络的切换过程（628,630,634）。

Abstract: Systems and methodologies are described that facilitate applying offsets and/or selectable hysteresis values to favor access points in cell reselection. In measuring and ranking surrounding access points in reselection, offsets can be applied to favorable access points to facilitate cell reselection thereto. The offset can positively affect measurements, and thus ranking as well, in some cases. Negative offsets can also be applied to lower measurements (and thus ranking) of some access points. Moreover, hysteresis values can be applied in measuring current cells to prevent frequent reselection. The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point.

Abstract: To determine a cell for usage in wireless communication, a signal-to-noise ratio or a signal-to-power ratio can be used in selecting an appropriate cell. However, cell selection can also configure to take both signal-to-noise ratio and signal-to-power ratio into account. Multiple available cells can be analyzed and a highest ranking cell can be selected through balancing the aforementioned ratios. In addition, to minimize transferring between cells, a limitation can be placed such that a cell is not left unless there is better of both the aforementioned ratios at another cell.

Abstract: The present disclosure presents example methods and apparatuses for improved cell searching in a wireless communications environment. For example, the disclosure presents example methods of wireless communication in a multiflow environment, which may include establishing a first flow between a serving radio network controller (S-RNC) and a first network entity, wherein the S-RNC controls the first network entity. Such example methods may also include establishing a second flow between the S-RNC and a second network entity. Furthermore, such example methods may include transmitting data to a user equipment (UE) via both the first flow and the second flow.

Abstract: Systems and methodologies are described that facilitate communicating PSC split information regarding neighboring cells. The PSC split information can be transmitted in one or more overhead messages selected based on network deployment. Where macro cells and femto cells provide PSC split information, which can be a PSC range for related cells, PSC list, etc ., the information can be transmitted in a low priority overhead message since it can be obtained at a source cell. Where only femto cells or closed subscriber group (CSG) cells provide PSC split information, the information can be transmitted in a higher priority more frequently transmitted message. In this regard, the information is available at target cells since not all devices can access CSG cells. Thus, by providing the PSC split information in a more frequently transmitted message, devices can retrieve the PSC split information early on in communications to lower power consumption.

Abstract: Methods and apparatuses are provided for determining available uplink bandwidth as an achievable throughput for a link. An available link capacity of a link with a cell for a user equipment is estimated based on a communication quality measured in the cell. An available fraction of cell resources for the user equipment over the link is also estimated based at least in part on received assistance information. An available bandwidth of the cell is then estimated as an achievable throughput for the user equipment over the link as a function of the estimated available link capacity and the estimated available fraction of cell resources. Moreover, a network procedure can be performed based at least in part on comparing the achievable throughput to one or more thresholds.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling communication of small data amounts while maintaining a RRC idle mode of operation for a UE. In an example, a UE is equipped to obtain a temporary radio bearer for communication of data, that meets one or more criteria for small data transmission, over a user plane in a UMTS or LTE based network, and transmit the data, over the user plane, using the temporary radio bearer while maintaining the UE in an RRC idle mode. A UTRAN entity may receive, over the temporary radio bearer assignment, the data from a UE in an idle mode, and send the data to a SGSN using a common small data connection. The SGSN may then send the data to a PGW.
