Patent number: 8537731Abstract: A system and method are described for reducing congestion in a wireless network. A wireless base station becomes congested when substantially all of the available base station airlink resources are being used during a period of time. It is useful, however, to distinguish between periods of congestion with few users and periods where a larger number of users are using the base station. When there are few users a congestion situation is not necessarily a problem, while it is more likely that users' quality of experience and quality of service suffers as the number of users increases. This system and method determines when a base station is congested and implements a congestion prime management scenario when the number of active users is above an activity threshold.Type: GrantFiled: March 26, 2010Date of Patent: September 17, 2013Assignee: Eden Rock Communications, LLCInventors: Chaz Immendorf, Eamonn Gormley

Patent number: 8538387Abstract: Single voicemail for dual-mode phones. Functionality is added to a dual-mode phone such that the dual-mode phone when operating in cellular mode sends a predetermined signal when it answers an incoming call.

Patent number: 8509780Abstract: The present application describes embodiments of a method and apparatus for determining handover parameters in a wireless overlay network. One embodiment includes modifying a bias value used to determine when to handover user equipment between a macrocell and a femtocell that overlays the macrocell. The bias value is modified in response to a change in one or more handover frequencies associated with the user equipment. Handovers of user equipment are triggered when a sum of the bias value and a measured value of the femtocell signal strength exceed a measured value of the macrocell signal strength.Type: GrantFiled: August 18, 2011Date of Patent: August 13, 2013Assignee: Alcatel LucentInventors: Kamakshi Sridhar, Hajo Bakker

Patent number: 8503401Abstract: A method and user equipment for performing a handover between a MBSFN and non-MBSFN areas in a communication network is provided. The communication network comprises a first cell constituting a MBSFN area, a second cell constituting the non-MBSFN area, and a reserved cell between the first and second cells and subordinate to the MBSFN area. Reserved cell indication information being broadcast in the reserved cell. The method including: receiving the reserved cell indication information to learn that a user equipment is located in the reserved cell; measuring in the reserved cell, for a preset service, a first signal strength based on MBMS transmission and a second signal strength based on a single-cell transmission; and selecting the first or second cells as a target cell during a period in which a difference between the first and second signal strengths is lower than a preset threshold.Type: GrantFiled: July 21, 2008Date of Patent: August 6, 2013Assignee: Alcatel LucentInventor: Yonggang Wang

Patent number: 8503400Abstract: A method for base station reselection in a wireless communications system is disclosed. The method may determine a first indication of signal strength for a first signal sent from a first base station and received by a user equipment (UE). The method may also determine a second indication of signal strength for a second signal sent from a second base station and received by the UE. The method may further determine a relative signal strength based on the first indication of signal strength and the second indication of signal strength. The method may also determine a Q factor based on the relative signal strength. The Q factor may be an indication of when base station reselection should be performed.Type: GrantFiled: September 18, 2008Date of Patent: August 6, 2013Assignee: Sharp Laboratories of America, Inc.Inventors: Kenneth J.

Patent number: 8504055Abstract: The present invention relates to methods and arrangements in a wireless communication system that enable a load balancing procedure in a network with HeNB GWs. The problem of the ineffective conventional load balancing procedure when used in a network with HeNB GWs, is addressed by a solution where the HeNB includes (510) an explicit indication of the reason for radio link establishment (load balancing establishment cause) in the S1AP INITIAL UE MESSAGE message (511) used to establish the S1 signaling connection associated with a user equipment to an MME, so that the HeNB GW (550) can perform an accurate MME selection based on the knowledge that the establishment is due to load balancing, i.e. an MME selection that realizes the required inter-MME load balancing.Type: GrantFiled: June 30, 2009Date of Patent: August 6, 2013Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jari Vikberg, Tomas Nylander, Johan Rune

Patent number: 8503438Abstract: According to one aspect of the invention, packets of a first type within a first data flow are routed to a destination through a packet core network. In response to a detection that packets of a second type are to be routed while routing the first data flow, a second data flow is created which is a sub-flow of the first data flow. Packets of the second type are routed via the second data flow to the destination without traversing the packet core network, while packets of the first type are routed via the first data flow traversing the packet core network.Type: GrantFiled: November 18, 2010Date of Patent: August 6, 2013Assignee: Stoke, Inc.Inventors: Heeseon Lim, Nishi Kant

Patent number: 8503410Abstract: The distance to a communicating party is detected using whether or not an electromagnetic-coupled RF field formation is achieved or not as simple measurement means. If the distance to the communicating party is short, i.e., if it is possible to form an RF field, then transmission power is reduced. As a result, power consumption is reduced. Since a reduction in transmission power is accompanied by restriction of the zone in which communication is possible, leakage of information is prevented and security is enhanced.Type: GrantFiled: November 16, 2005Date of Patent: August 6, 2013Assignee: Canon Kabushiki KaishaInventor: Kanichi Yoshino
