Patent number: 8583118Abstract: A mobility management control method and system that can redress the uneven loads on base stations in a mobile communications network are provided. Multiple base stations in a tracking area each have a mobile station mobility management function. A base station positioned at an edge of the tracking area monitors its own load state. Depending on its own load state, the base station relocates to another base station a location management function with respect to a new location management request, or a location management function as a mobility management serving base station with which location management has been already performed for a mobile station.Type: GrantFiled: March 13, 2007Date of Patent: November 12, 2013Assignee: NEC CorporationInventor: Jinsock Lee

Patent number: 8583137Abstract: Techniques for dynamically varying coverage in a multi-carrier communication system are described. A sector may operate on multiple carriers. The sector may vary coverage on a given carrier k based on its load, so that less interference may be caused to other sectors when the sector load is light. In one design, the sector may communicate on a first carrier at a first transmit power level and on a second carrier at a second transmit power level equal to or lower than the first transmit power level. The sector may vary the second transmit power level based on its load to vary the coverage of the second carrier. The sector may reduce the second transmit power level to zero or a low level if the sector load is light. The sector may also vary the second transmit power level based on a function of sector load or a switching pattern.Type: GrantFiled: May 14, 2009Date of Patent: November 12, 2013Assignee: QUALCOMM IncorporatedInventors: Ramin Rezaiifar, Peter J.

Patent number: 8583114Abstract: A method of identifying an available channel of a plurality of frequency channels defined in a radio frequency spectrum for use by a transmitting station, wherein scanning for an available channel in a frequency spectrum is performed by a scanning method in which a bidirectional search is performed away from an initial channel frequency. The method may include steps to take when a boundary of the spectrum is encountered, and may also take into account existing information concerning channel reservation. A related scanner and radio apparatus is also described.Type: GrantFiled: January 19, 2012Date of Patent: November 12, 2013Assignee: Kabushiki Kaisha ToshibaInventors: Siva Kupanna Subramani, Zhong Fan, Simon Martin Daniel Armour, Dritan Kaleshi

Patent number: 8576805Abstract: A subscriber controlled registration protocol, a subscriber monitors a congestion indicator signal broadcasted by a base station with which it desires to register. If the congestion indicator signal indicates that the base station is operating in a congested state, the mobile station selects another base station in the system. Otherwise, it attempts to register with the first selected base station.Type: GrantFiled: June 16, 2006Date of Patent: November 5, 2013Assignee: IPR Licensing, Inc.Inventors: James A. Proctor, Jr., Dennis D. Ferguson

Patent number: 8577385Abstract: A group transfer function (GTF) receives a plurality of inputs and media for delivery to a plurality of mobile devices. The mobile devices are served by a plurality of cells potentially having a plurality of different radio access technologies such that each mobile device is wirelessly connected to one of the cells. The GTF applies policy rules to the inputs to determine, for each mobile device, content delivery using point-to-multipoint or point-to-point media transport based on the capabilities of the servicing cell. The GTF initiates an allocation of a set of resources in each cell to transport the media to each mobile device in the group using the determined media transport for that mobile device. Media is then replicated by the GTF for delivery to the mobile devices over the allocated resources.Type: GrantFiled: July 18, 2011Date of Patent: November 5, 2013Assignee: Motorola Solutions, Inc.Inventors: James A. Marocchi, Trent J. Miller, Deborah J. Monks

Patent number: 8576712Abstract: A method and apparatus for providing a reliable Voice Extensible Markup Language (VXML) over packet networks such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) network are disclosed. For example, a service provider may utilize a plurality of content servers that can be accessed by at least one telephony browser. The telephony browser can reach the content browsers directly as well as through a shared server that may load balance among the content servers. When a request for a VXML content, e.g., a VXML application, is received, the telephony browser sends the request to the shared server. If the request fails or a response is not received prior to expiration of a predetermined time interval, then the telephony browser sends a second request directly to one of the content servers that is capable of providing the requested content.Type: GrantFiled: May 31, 2006Date of Patent: November 5, 2013Assignee: AT&T Intellectual Property II, L.P.Inventors: Ricardo Sabat, Shankarnarayan Sivaprasad
