Abstract: 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.

Abstract: 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.

Abstract translation: 这里描述了使用关于宏RF网络的覆盖或容量分类来管理毫微微小区与服务提供商网络（SPN）的注册以避免信令过载的方法和系统。 在多个毫微微小区所在的区域内的大规模断电之后，毫微微小区可以在大约相同的时间上电并尝试向SPN注册。 毫微微小区可以扫描从宏网络接收的RF信号，并且在发射RF信号时对接收的RF信号进行相对于宏网络的容量或覆盖范围的分类。 SPN内的设备可以确定接收的RF信号的分类是否与丢弃或接受与分类的RF信号相关联的注册请求相关联。 SPN设备可以接受注册请求或丢弃注册请求，并请求毫微微小区传送另一个注册请求。

Abstract: 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.

Abstract: Example methods and systems for requesting information from the Internet Domain Name System (DNS) based on a destination and one or more codecs of a source specified within a computer-readable invitation to establish a communication session are described. A source gateway or a user agent device can generate the invitation. A DNS record associated with the destination can specify codecs used by the destination or a gateway the destination uses to carry out communication sessions. A proxy server that received the invitation and the DNS record can select a gateway that uses a codec that matches a codec used and preferred by a gateway. The proxy server can forward the codec to selected gateway, in particular, to an IP address and port associated with the selected gateway, for notifying the destinations of the requested communication session. The invitations can comprise SIP INVITE messages.

Abstract: 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.
