摘要： An apparatus and method for locating a remote station operating in analog mode, and that may not have a sense of network time, using an inverted GPS approach. The invention also enables remote stations operating in analog mode that do not know true GPS time to determine their own location. A time stamp, reflecting the approximate time a satellite range measurement is made, is assigned to the measurement at either the remote station or elsewhere in the network. The difference between true GPS network time and the measurement time is treated as a variable “error” in measurement, the length of which is unknown. This variable error is determined and used in determining the physical location of the remote station.

摘要： A method and apparatus for efficiently transmitting location assistance information to a mobile communication device over a control channel with a minimal impact on the capacity of the control channel. A position location server provides a difference between satellite locations which have been computed using Almanac data and then Ephemeris data. Sending only the difference between the locations and clock corrections computed using the two different data types, the total amount of information to be transmitted to a mobile communication device is significantly reduced. Furthermore, by providing rate of change information, the method and apparatus allows the location assistance information to remain valid for a relatively long time after it is has been received by the mobile communication device.

摘要： A method and apparatus for use in a hybrid position location system. The method and apparatus combines measurements from Global Positioning System (GPS) and terrestrial transceiver stations to compute the location of a device. An algebraic solution to hybrid position location system equations is output from the method and apparatus. The method and apparatus determines the position of a device using a non-iterative method, as against the use of a conventional iterative least mean square method. The method of the present invention can be used to solve the location system equations in scenarios where a non-iterative solution is desirable. In certain scenarios, the location system equations may have two possible solutions. An iterative method would converge on one of the solutions, without any indication of the existence of the other ambiguous solution. Moreover, the iterative method may converge on the incorrect of the two ambiguous solutions. Use of the presently disclosed method and apparatus yields both the ambiguous solutions. The disclosed method may be followed up with iterative methods, using the solutions from the algebraic method as initial estimates of the device location for the iterative method. A different process can then select the correct solution. Thus, the algebraic method can be used to detect the existence of ambiguous solutions, and to find both solutions.

摘要： Method and apparatus providing enhanced sensitivity for GPS receivers by allowing coherent integration of a correlation over several code periods of a GPS signal in one embodiment, and by performing a time to frequency domain conversion to the output from a correlation processor in a second embodiment. In the case in which coherent integration is performed over several code periods, advantage is taken of the fact that CDMA cellular telephone base stations transmit information that allows the receiver to determine GPS time before beginning a GPS signal acquisition process. The integration can be expanded to include code periods from more than one bit period, if the GPS receiver takes advantage of the fact that known bit patterns are transmitted at particular times within the transmission from a GPS satellite. If no base station is within range, then the output from a correlator that integrates a correlation over one code period is used to generate values that are input to in a discrete time domain to frequency domain transform. The output from the transform will indicate the presence of a signal from a particular satellite and the offset between locally generated signal and the received GPS signal.

摘要： Methods and apparatus for controlling transmission of a base station, such as a Femto cell, based on the determined quality of a backhaul connection to a network are disclosed. In particular, a quality of a backhaul connection of a base station to a node in a communication network is determined. Based on this quality determination, transmission from the base station is either limited or stopped when the determined quality fails to meet a predefined condition. The degradation in quality of the backhaul connection, for example, affects the ability of the base station to offer sufficient service to access terminals. By limiting or stopping wireless transmission of the base station when the backhaul quality is degraded, access terminals either currently accessing the base station or attempting to connect to the base station can then more efficaciously hand off to another base station or access point.

摘要： Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

摘要： Systems and methodologies are described that facilitate indicating global cell identifier (GCI) reporting in wireless communication to mitigate confusion caused by physical cell identifier (PCI) reporting in heterogeneous deployments. In particular, mobile devices can report GCI of access points to disparate access points to facilitate communication therebetween, such as during handover. Mobile devices can indicate GCI reporting during a system access request by selecting an access sequence corresponding to subsequent GCI reporting. Based on the access sequence, an access point can grant additional resources to receive the GCI, and the mobile device can communicate GCI over the resources. Using the GCI, the access point can communicate with a disparate access point related to the GCI.

摘要： An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

摘要： 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.

摘要： Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.
