Abstract: Apparatus and methods of performing interference mitigation in a communication network. The interference mitigation can include a controller sending a message to a first access point instructing the first access point to measure at least one signal transmitted by a first wireless terminal communicating a signal having known characteristics; the controller receiving from the first access point signal measurement information; and the controller communicating at least some of the signal measurement information received from the first access point to a second access point.

Abstract: A system and method for establishing a multimedia session between a wireless user terminal and a network device. Embodiments include systems and methods for receiving a request from a wireless terminal initiating a call event to the network device; generating and sending a multimedia session invitation to a multimedia call control entity requesting a multimedia session with the network device; receiving a multimedia status message from the multimedia call control entity indicating the progress of initiating the multimedia session; and triggering setup of a radio access bearer to handle the multimedia session in response to the multimedia status message.

Abstract: Methods and apparatuses are provided for obtaining downlink or uplink signal characteristics of at least one access point in a network. The signal characteristics may be obtained through user equipment receiving the signal characteristics, through the at least one access point, or through another access point. Frequency or timing offset between two or more access points may be determined based on the obtained signal characteristics, where the frequency or timing offset may be handled through post processing. For example, a clock servo may be controlled or adjusted in response to the determined offset, the absolute frequency of a master network oscillator may be calibrated, traffic anomalies within the network may be detected and corrected, and/or respective clocks of the two or more access points may be synchronized.

Abstract: The present application describes methods for performing proxy communications between mobile stations connected to a femtocell network and a central telephone network controlled by a network operator. In some embodiments, a private branch exchange is configured to temporarily assign identification numbers to the mobile stations connected to the femtocell network. Incoming calls are directed to the private branch exchange rather than the connected mobile stations. After receiving the incoming call, the private branch exchange routes the incoming call to the correct mobile station. In some embodiments, these methods also enable mobile stations to cross between femtocell coverage areas within the same femtocell network without constantly updating the central network operator.

Abstract: Apparatus and methods for reconfiguration of a communication environment based on loading requirements. Network operations are monitored and analyzed to determine loading balance across the network or a portion thereof. Where warranted, the network is reconfigured to balance the load across multiple network entities. For example, in a cellular-type of network, traffic loads and throughput requirements are analyzed for the access points and their user equipment. Where loading imbalances occur, the cell coverage areas of one or more access points can be reconfigured to alleviate bottlenecks or improve balancing.

Abstract: Methods and apparatus are described that enable a deployment of a system of wireless nodes, e.g., femtocells, which can self-configure themselves into a balanced and optimized wireless network. In various embodiments, access points switch between a network monitoring mode in which network monitoring is performed and a communications mode in which the access point serves one or more wireless terminals and communicates traffic data to/from the wireless terminals. Traffic data transmission to wireless terminals are not supported in network monitoring mode. Based on information gathered from one or more access nodes while they operating in network monitoring mode of operation, access point configuration information is generated and one or more access points are automatically configured.
