Abstract:
A method and apparatus for facilitating capacity monitoring and recommending action for a wireless network is provided. The method may comprise: obtaining data associated with one or more capacity attributes and one or more key performance indicators (KPIs) associated with a network, calculating network level values for the one or more KPIs from the obtained data, generating performance data graphs by plotting a first of the one or more KPIs against a second of the one or more KPIs, analyzing the one or more performance data graphs to determine at least one alarm threshold, and monitoring the one or more capacity attributes to determine if any of the at least one alarm thresholds has been triggered.
Abstract:
An apparatus and method for access stratum management comprising reading system information from at least one broadcast channel from a current serving cell; and determining if an available cell is suitable for a user equipment (UE) based on information included in the broadcasted system information, wherein the determining step comprises at least one of the following: comparing system release information of the user equipment (UE) from the broadcasted system information; determining if the available cell supports a specific feature which makes the available cell suitable for optimum performance of the UE; or determining if the available cell and a frequency combination are suitable for a UE type.
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:
User Equipments (UEs) can be adapted to enter into a lower RRC state from a higher RRC state, and search for one or more layers of higher priority within a predetermined period of time upon entering into the lower RRC state. According to at least one aspect, this search for one or more layers of higher priority may be performed irrespective of RF quality of a current serving cell. According to at least another aspect, this search for one or more layers of higher priority may be conducted within the predetermined period of time if a wait period has elapsed since the UE camped on the current serving cell. If the wait period has not elapsed since camping on the current serving cell, the search for one or more layers of higher priority may be performed within the predetermined period of time following a duration of the wait period.
Abstract:
In an embodiment, a user equipment (UE) determines that a client application has entered a period of transmission inactivity whereby the UE will not be required to transmit data on behalf of the client application. The UE selectively transmits a transmission inactivity notification to an access network (AN) to notify the AN of the transmission inactivity period. The AN receives the transmission inactivity notification and determines to transition the UE from a first state to a second state based at least in part on the received transmission inactivity notification, the second state associated with lower-power consumption of the UE than the first state. The AN sends instructions to the UE to facilitate the transition of the UE from the first state to the second state. In another embodiment, the AN can send instructions to the UE to prohibit the UE from sending transmission inactivity notifications.
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:
Systems and methodologies are described that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and a CSG indication that distinguishes between the base station permitting access to members of the CSG and permitting access to members and non-members of the CSG. For instance, the CSG ID can uniquely identify the CSG corresponding to the base station. A mobile device can receive the CSG ID and the CSG indication from the base station. Further, the received CSG ID can be compared to CSG IDs included in an allowed CSG list to recognize whether the mobile device is a member or a non-member of the CSG. Moreover, a preference for selecting the base station as compared to a disparate base station can be generated as a function of the received CSG ID and CSG indication.

An apparatus and method for reporting battery information includes receiving configuration information including a reporting mode from a network entity; collecting the battery information of a user equipment (UE); preparing the battery information in the reporting mode; and sending the battery information in the reporting mode over a communications transport mechanism to the network entity. In one aspect, the apparatus and method for receiving battery information includes selecting and configuring a reporting mode; sending configuration information comprising the reporting mode over a communications transport mechanism to a user equipment (UE); and receiving the battery information from the UE, wherein the UE uses the configuration information and the reporting mode.
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.
