Based on the first tracking area configuration, the second tracking area configuration, the determined location, and the determined mobility a handover of the wireless device from the first carrier to the second carrier is performed.Type: GrantFiled: April 26, 2012Date of Patent: April 15, 2014Assignee: Sprint Spectrum L.P.Inventors: Daniel Vivanco, Krishna Sitaram

Publication number: 20140099969Abstract: In accordance with an example embodiment of the present invention, a method includes receiving a connection request in uplink signaling from a user equipment, the user equipment being located in a cell; making a determination whether the user equipment can be connected and, if it is determined that the user equipment cannot be connected, informing the user equipment by downlink signaling, as a response to the connection request, that the user equipment cannot be connected. The downlink signaling includes information that indicates that the user equipment should de-prioritize a current carrier frequency or current radio access technology, and can further include a timer value to indicate a period of time for which the current carrier frequency or current radio access technology is to be de-prioritized. The method can be executed by an evolved NodeB (eNB) of an evolved universal terrestrial radio access network (E-UTRAN).Type: ApplicationFiled: March 6, 2013Publication date: April 10, 2014Applicant: NOKIA CORPORATIONInventor: NOKIA CORPORATION

Patent number: 8693477Abstract: A system and method for load balancing session initiation protocol (SIP) traffic based on bridging and tracking transactions and connections between frontend and backend devices. The method includes receiving a SIP message and parsing a header of the SIP message. The parsing may include selecting a transaction identifier. The method further includes accessing a transaction table based on the transaction identifier and selecting a connection for forwarding the SIP message. The SIP message is then forwarded by the selected connection.Type: GrantFiled: November 14, 2011Date of Patent: April 8, 2014Assignee: Brocade Communications Systems, Inc.Inventors: Yan-Zhe Wang, Mani Prasad Kancherla

Patent number: 8694012Abstract: Methods and apparatuses for two or more neighboring base stations to access a plurality of radio resources are described. The method includes defining a channel quality requirement by one or more access conditions and assigning the plurality of radio resources to the channel quality requirement, wherein a neighboring base station has access to the plurality of radio resources and the neighboring base station neighbors a target base station. The method also includes allowing the target base station access to the plurality of radio resources if the target base station satisfies the channel quality requirement.Type: GrantFiled: February 1, 2010Date of Patent: April 8, 2014Assignee: Intel Mobile Communications GmbHInventor: Markus Mueck

Patent number: 8694014Abstract: A method and corresponding system is provided for managing registrations and reducing registration failure. According to at least one embodiment of the method, a wireless communication device (WCD) receives a channel list message (CLM) in a given coverage area. The WCD may determine that it is not within coverage of a first channel specified in the CLM. The WCD may make this determination before attempting to register for service on the first channel. In response to making this determination, the WCD may register for service on another channel specified in the received CLM.Type: GrantFiled: February 7, 2011Date of Patent: April 8, 2014Assignee: Sprint Spectrum L.P.Inventors: Jasinder P. Singh, Sachin R. Vargantwar, Maulik K. Shah

Patent number: 8694018Abstract: A method and apparatus for controlling a Network Load Balancing (NLB) algorithm that balances a traffic load between multiple downlink (DL) sectors in a cellular telecommunication network. A Connection Integrity Preservation (CIP) algorithm, which runs on top of the NLB algorithm in the Radio Network Controller/Base Station Controller (RNC/BSC), minimizes the risk of degrading network performance due to NLB offload decisions. The CIP algorithm may override an NLB offload decision, for example, if there have been too many offload failures, there are no target DL sectors available to acquire an offloaded Access Terminal (AT), or the offloaded AT is not acquired within a threshold time period. The CIP algorithm ensures required metrics are collected, and minimizes the impact on RNC/BSC processing due to Routing Update messages needed to make offload decisions. The invention enables the NLB algorithm to realize its potential without negative side-effects.Type: GrantFiled: June 16, 2011Date of Patent: April 8, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Miroslav Budic, Abdennaceaur Lachtar, Narendra Tilwani, Pulin Chhatbar

Patent number: 8693450Abstract: In one embodiment, different physical layer standards are segregated into different frequency channels. In one implementation, 802.11b traffic and 802.11g traffic are segregated into different frequency channels. A network management tool allows the user to specify channels to either, e.g., 802.11b-only, 802.11g-only, 802.11b preferred and 802.11g discouraged, or 802.11g preferred and 802.11b discouraged. Access points are given the capability of preventing or discouraging client traffic of either given type.Type: GrantFiled: June 4, 2010Date of Patent: April 8, 2014Assignee: Cisco Technology, Inc.Inventors: Tania Sung-Yi Chen, Bretton Douglas, Arnold Bilstad

Publication number: 20140094186Abstract: A method for managing power consumption of a radio access network. The method includes: defining a cluster including at least two radio resource units of the radio access network; defining a parameter indicative of a performance of the cluster and of a power consumption of the cluster, the parameter being expressed as a function of traffic throughputs carried by the radio resource units of the cluster; calculating optimum traffic throughputs as values of the traffic throughputs carried by the radio resource units of the cluster which optimize the parameter; and distributing traffic amongst the radio resource units of the cluster such that the radio resource units of the cluster carry the calculated optimum traffic throughputs.Type: ApplicationFiled: June 7, 2011Publication date: April 3, 2014Applicant: TELECOM ITALIA S.p.A.Inventors: Sergio Barberis, Giorgio Calochira, Marco Caretti, Dario Sabella
