Abstract: The present invention facilitates handoffs for a mobile terminal in a wireless access network that is capable of supporting different types of handoffs. The different handoff types may include soft handoffs and fast base station switching (FBSS). In operation, context information associated with supporting wireless communications between the wireless access network and the mobile terminal are determined.

Selecting the specific type of handoff to use may also be based on the level of context information that is available, the actual content of the context information, application preferences, channel conditions, base station or mobile terminal capabilities, or any combination thereof.

Abstract: A user equipment UE determines that a neighbor cell is higher priority than a serving cell, measures neighbor cell signal strength in n>1 iterations, and analyzes them for reselecting from the serving cell to the neighbor cell. Each measurement iteration is spaced from one another by a time interval (e.g., 1 DRX) that is specific for the neighbor cell being higher priority. In various embodiments, the UE measures while in a Cell-PCH, URA-PCH or idle state/mode and the first iteration is taken at the first available measurement opportunity after transitioning to that state/mode. The UE reselects to the neighbor cell based on the analyzed signal strengths; in one embodiment the decision to reselect is without regard to signal quality of the serving cell; and in another the decision is without regard to whether a reselection condition remains satisfied for a specified time period Treselection.

Abstract: A system, computer-readable medium, and method of operating a dual-mode WiMAX and CDMA communications device capable of operating in a CDMA mode or a WiMAX mode includes receiving a first base station (BS) location message from the BS and storing the received location as a current BS location. The BS location is compared to stored region coordinates for the different regions, and the comparison is used to determine a particular region in which the dual-mode device is currently located. Analysis determines whether a WiMAX market is located within the particular region. If no WiMAX markets are located, the dual-mode device is operated in the CDMA mode. If one or more WiMAX markets are located within the particular region, a determination is made as to whether the BS location is within a WiMAX market and, if so, the dual-mode device is placed in a WiMAX mode of operation. Battery power is conserved by avoiding WiMAX transmission when WiMAX service is not available at the current BS location.

Abstract: Techniques for using wireless devices to implement sensor networks are described. For cognitive radio, a wireless device obtains measurements for a first system (e.g., a broadcast system) with which the wireless device is not in communication. The wireless device sends the measurements and associated location information and/or timestamps via a second system (e.g., a cellular system). A server receives measurements from a number of wireless devices and determines the coverage of the first system based on the measurements. For other applications, a wireless device obtains sensor information from at least one sensor at the wireless device and sends the sensor information and associated location information and/or timestamps via a wireless system. A server receives the sensor information and associated information from a number of wireless devices, aggregates the sensor information, and constructs a map. The wireless device may develop a user profile based on the sensor information and associated information.

Abstract: Ambiguity (e.g., confusion) associated with access point identifiers may be resolved by querying candidate target access points and/or by using historical records indicative of one or more access points that the access point has previously accessed. For example, messages may be sent to access points that are assigned the same identifier to cause the access points to monitor for a signal from an access terminal that received the identifier from a target access point. The target access point may then be identified based on any responses that indicate that a signal was received from the access terminal. A mapping may be maintained for that access terminal that maps the identifier to that access point so that the mapping may be used to resolve any future confusion associated with the use of that identifier by that access terminal.

Abstract: A call loop avoidance capability is provided for preventing formation of a call loop resulting from handling of a mobile terminated (MT) call in parallel with a location update for a mobile device (MD) in a wireless communication network. The call loop avoidance capability prevents formation of a call loop between an old mobility and call management entity (MCME) and a new MCME when delivery of an MT call to an MD is performed while the MD is in the process of moving from the old MCME to the new MCME using a location update procedure. An enhanced call routing procedure supports direct delivery of the MT call from the new MCME to the MD (rather than delivery of the MT call by the new MCME to the MD via the old MCME) in order to prevent formation of a call loop between the old MCME and the new MCME.

Abstract: An automated portable call collection unit (APCCU) may gather information used in testing the accuracy of a wireless mobile device locating system. A GPS ground truth detector may detect the location of the APCCU based on GPS signals. A cellular GPS detector may detect GPS signals identified by a signal-identification communication from the locating system.

The HSS then stores the access network information in the subscriber profile for the user. Nodes in the IMS network that retrieve the subscriber profile may acquire the access network information to provide services based on the access network information.

Abstract: The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.
