| 20100265893 | Network Methods and Systems for Maintaining PLMN Continuity When Moving Between Networks of Different Types as a Function of PLMN Continuity Preference - Network methods and systems for maintaining PMLN continuity when moving between networks of different types as a function of PLMN continuity preference are provided. PLMN continuity preference concerns a preference for the mobile station when transferring from a first network type, such as cellular, to a second network type, such as GAN to reduce the possibility of dropping calls, for example. The network receives this preference information from the mobile station, and the network responds to registration requests based on the preference. | 10-21-2010 |
| 20100265926 | Mobile Station Methods and Systems for Maintaining PLMN Continuity When Moving Between Networks of Different Types as a Function of PLMN Continuity Preference - Mobile station methods and systems for maintaining PMLN continuity when moving between networks of different types as a function of PLMN continuity preference are provided. PLMN continuity preference concerns a preference for the mobile station when transferring from a first network type, such as cellular, to a second network type, such as GAN to reduce the possibility of dropping calls, for example. The mobile station transmits this preference to the network, and the mobile station then perform network selection based on the preference. | 10-21-2010 |
| 20100267384 | Systems and Methods for Prioritizing Network Selection to Achieve PLMN Continuity When Moving Between Networks of Different Types - Systems and methods for prioritizing network selection to achieve PLMN continuity when moving between networks of different types are provided. In network centric embodiments, the network generates a PLMN list that prioritizes networks for which PLMN continuity is possible, for example when moving from cellular to GAN or vice versa. In mobile station centric embodiments, the mobile station generates a PLMN list that prioritizes networks for which PLMN continuity is possible, for example when moving from cellular to GAN or vice versa. This can be based on the mobile station recognizing past behaviour of the networks. | 10-21-2010 |
| 20100268674 | Systems and Methods for Achieving PLMN Continuity When Moving Between Networks of Different Types Through Network Selection - Systems and methods for achieving PLMN continuity when moving between networks of different types through network selection are provided. When a mobile station moves from a first network type, such as cellular, to a second network type, such as GAN, if there is a PLMN discontinuity, this may result in a dropped call. In order to avoid this, networks for the first network type and the second network type are selected such that there is PLMN continuity. This can involve reselection of a different cellular network than one currently providing service to the mobile station. | 10-21-2010 |

| 20080261655 | APPARATUS, AND ASSOCIATED METHOD, FOR FACILITATING NETWORK SELECTION USING ACCESS TECHNOLOGY INDICATOR - Apparatus, and an associated method, for facilitating selection of an I-WLAN PLMN. A PLMN listing is created and maintained at a wireless device. The listing includes entries that identify PLMN together with their associated access technology indicators. The wireless device creates a list of available I-WLAN PLMNs. And a selector and comparator compare identities on the listing together with the list of available I-WLAN PLMNs. Selection is made of a PLMN on both the listing and the list and also exhibits an appropriate access technology capability identified by the access technology indication. | 10-23-2008 |
| 20090061861 | Scheme for Providing Regulatory Compliance in Performing Network Selection in a Foreign Country - In one embodiment, a scheme is disclosed for network selection in a user equipment (UE) device. A determination is made that a network identified by a received network identity code is an equivalent home network with respect to a subscriber identity associated with the UE device. Responsive to that determination, a further determination is made that the equivalent home network is in a geographic region of a home country associated with the subscriber identity, whereupon a scanning of all equivalent home networks is performed in accordance with the scanning procedures specified for the geographic region. | 03-05-2009 |
| 20100040171 | SYSTEMS AND METHODS FOR COMMUNICATING USING ASK OR QAM WITH UNEVEN SYMBOL CONSTELLATION - Systems and methods of performing ASK or QAM modulation with uneven distance between symbols are provided. These are used to provide differing BER performances among bits sent from a transmitter to a receiver. | 02-18-2010 |
| 20110223935 | Cross-Technology Coverage Mapping System and Method for Modulating Scanning Behaviour of a Wireless User Equipment (UE) Device - A network node provides coverage information to wireless UE devices from a database that correlates coverage information for a radio access network with geographic area locations. The network node accepts updates to the coverage information for the radio access network via a first interface and downloads coverage information from the database to a wireless user equipment (UE) device via a second interface. | 09-15-2011 |

| 20110280154 | Method and Apparatus for Management of a Global Wireless Sensor Network - Methods and apparatus for global wireless sensor network architecture and protocol for remote supervision, asset control and operational management based on localized clusters of autonomous sensor/supervision/operational sensor nodes capable of ad hoc interconnection with nearby nodes and connection to gateway nodes with increased network functionality. These localized cluster nodes send data to gateway nodes either directly or through multi-hop transactions. The gateway nodes are, in turn, connected to other gateway nodes and operations control centers either through wireless or wired data communications links. Utilizing the Internet for long range interconnectivity, the network is scaleable to a global level. The resulting network is based on an ad hoc mesh topology to allow flexibility in network modification and expansion and is comprised of a tiered structure defined by increasing functionality. A current application for this technology is the remote control and supervision of lighting systems for facilities and municipalities on a local, national and/or global basis from centralized regional operations centers. | 11-17-2011 |
| 20120008542 | Distributed Ad Hoc Mesh Network Protocol for Underground Mine and Hazardous Area Communications - Methods and apparatus for forming and maintaining an ad hoc mesh network suitable for reliable voice and data communications in underground, industrial and other hazardous environments. This invention includes support for cooperative negotiation of dedicated transmission bandwidth for all fixed network nodes, determination of network time synchronization without a pre-determined time master, discovery and merging of adjacent ad hoc mesh networks, and routing techniques for voice, data and network status packets which react instantaneously to network topology changes. Furthermore this invention provides a reliable communication network for mobile nodes carried by personnel and sensor nodes that are fixed or mobile that supports voice, data and tracking/situation awareness. A current application for this technology is a coal mine communication system with an operations center to dispatch, monitor and control coal mine operation including communication and location of mine personnel, and environmental conditions in the mine. | 01-12-2012 |
