摘要： Methods and systems for using coverage or capacity classifications regarding a macro RF network to manage registration of femtocells with a service provider network (SPN) so as to avoid signaling overload are described herein. After a wide-scale power outage within an area where multiple femtocells are located, the femtocells can power on and attempt to register with the SPN at about the same time. The femtocells can scan RF signals received from the macro network and classify the received RF signals with respect to capacity or coverage of the macro network at the time of transmitting the RF signals. A device within the SPN can determine whether classification of the received RF signals is associated with dropping or accepting a registration request associated with the classified RF signals. The SPN device can accept the registration request or drop the registration request and request the femtocell to transmit another registration request.

摘要： A method and system for controlling broadcast of system identification. A base station may broadcast in one or more timeslots of a control channel, as a System Identifier (SID) of the base station, a particular SID, but may broadcast in one or more other timeslots of the control channel, as a SID of the base station, a different SID. In addition, when a mobile station registers to be served by the base station, the base station may determine which slot(s) of the control channel the mobile station will monitor and may broadcast in the determined slot(s) a SID that may help to keep the mobile station from transitioning to be served by a different base station.

摘要： Embodiments are described that may help to provide wireless service in a circuit-switched fall back scenario. In particular, when a user entity (UE) falls back from a first network to a second network to conduct a voice call, the first network may instruct the UE to scan a certain predetermined channel or channels for coverage from the second network. However, certain types of base stations typically operate on unlisted channels that differ from the predetermined channels that the UE is instructed to scan. Accordingly, a UE may pre-emptively scan unlisted channels, and report any unlisted channel that is detected to the first network. The first network can then coordinate with the second network to re-provision the base station that was operating on an unlisted channel, to instead operate on one of the predetermined channels that a UE will be instructed to scan during fall back to the second network.

摘要： A method and corresponding system is provided to help strike a balance between alleviating load among macro cells and reducing excessive signaling when UEs travel through small cells. In one embodiment of the method, a UE may function to receive an indication of the size of a coverage area, calculate current speed, determine that the calculated speed exceeds a threshold speed, and responsively hand over to a different coverage area. In another embodiment of the method, a RAN entity may function to estimate of the size of a coverage area, receive an indication of the current speed of a UE traveling through the coverage area, determine that the calculated speed exceeds a threshold speed, and responsively instruct the UE to hand over to a different RAN. Other examples are possible.

摘要： A system and method for determining base station location from neighbor lists of client devices is disclosed. When base station attempts and fails to acquire a satellite-based location fix, it can identify client devices operating within its service range, and query them for their respective neighbor lists. Upon receiving neighbor lists from one or more of the queried client devices, the base station can merge the lists into a composite list. The base station can then determine the locations of the base stations in the composite list, and compute a centroid from the locations. The base station can then adopt the centroid location as its own location.

摘要： A method and corresponding system is provided help establish a zone-based paging configuration. In accordance with the method, a RAN entity may evaluate the level of traffic in several small cells of the RAN, identify those small cells that have at least a threshold level of traffic, and responsively construct a new tracking area that includes the identified small cells. In another aspect of the method, a UE that is registered in a current tracking area, may move into coverage of a new sector and receive from a base station associated with the new sector two or more tracking area IDs. The UE may then determine that at least one of the tracking area IDs is indicative of the tracking area in which the UE is currently registered, and responsively operate in the new sector without transmitting a tracking area update message.
