Methods and systems for facilitating placement of a small cell in a network are provided. A small cell may be positioned such that it is communicatively coupled to a macro cell to provide a relay backhaul to a wireless network. The small cell may be configured to provide feedback of some form when the small cell is moved from a suitable location, to facilitate desired placement and use of the small cell. The feedback may be in the form of a change in functionality of the one or more feedback components.

Facilitating desired placement of a small cell

A wireless communication network serves data content to a wireless user device. An access wireless relay wirelessly receives a user request for the data content from the wireless user device. The access wireless relay wirelessly transfers the data content to the wireless user device when it stores the data content. When the access wireless relay does not store the data content, it transfers content requests having a Time-To-Live (TTL). Serving wireless relays receive the content requests during the TTL. The serving wireless relays transfer the data content to the access wireless relay if they store the data content. The serving wireless relays forward the content requests with the TTL when they do not store the data content. Terminating wireless relays receive the content requests after the TTL. The terminating wireless relays stop forwarding the content requests.

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.

Intelligent re-provisioning of base stations for circuit-switched fallback

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.

Presently disclosed are methods and systems to dynamically adjust base station configurations based on the altitude of the base station. One embodiment takes the form of a method carried out by a cellular base station system. The method includes determining that an altitude of a cellular base station exceeds a threshold. The method also includes configuring the cellular base station with one or more operational parameters based on the determined altitude. The one or more operational parameters includes at least one parameter selected from the group consisting of a transmit power, a carrier frequency, a handoff parameter, and a whitelist.

Dynamically adjusting base station configuration based on altitude

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.

Small cell handover technique based on speed

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.

Configuration of tracking area layers

Disclosed herein are systems and methods for dynamically configuring femtocell pilot beacon based on macro-network load. An embodiment takes the form of a method of operating a wireless network system that includes a first base station operating on a first frequency and one or more second base stations operating on a plurality of second frequencies. The method includes transmitting a frequency-hopping pilot beacon among the plurality of second frequencies. The method further includes determining loading on each of the second frequencies and in particular that a given one of the second frequencies is more heavily loaded than at least one other, and responsively prioritizing transmission of the frequency-hopping pilot beacon on the given frequency as compared to the at least one other frequency.

Systems and methods for dynamically configuring femtocell pilot beacon based on macro-network loading

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.

Determination of base station location based on other serving locations available to client devices

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.

Methods and systems for using macro coverage to manage femtocell registrations, so as to avoid signaling overload

Systems and methods are disclosed herein for managing the extent of registration signaling that a communication device sends when activating a network process, based on how long the process was turned off. For instance, if the device turns off without deregistering from a communication network and then turns on while the network registration is still current, an example system or method may help the device to recognize this situation and reduce unnecessary signaling associated with restarting a network process.
