20100246468 | REGULATING THE SCOPE OF SERVICE GEOGRAPHICALLY IN WIRELESS NETWORKS - In an embodiment, a network communication entity obtains a location associated with an access terminal that is attempting to participate in a communication service, determines whether the obtained location satisfies a relationship with a defined location region, the defined location region establishing a first level of service restriction for the communication service within the defined location region and establishing at least a second level of service restriction for the communication service outside of the defined location region, and restricts the access terminal in accordance with the first or second level of service restriction for the communication service based on the determination. The network communication entity may correspond to the access terminal, an access network or an application server. If the access terminal detects a current, imminent or future service restriction, the given access terminal can initiate handoff to another service mechanism and/or inform the user of the service restriction. | 09-30-2010 |
20100260086 | MANAGING A REVERSE LINK TRANSMISSION POWER LEVEL SETPOINT DURING PERIODS OF INACTIVITY ON THE REVERSE LINK IN A WIRELESS COMMUNICATIONS SYSTEM - Embodiments include managing a reverse link transmission power level setpoint during periods of data inactivity on a reverse link traffic channel in a wireless communications system. At an access terminal, upon detecting reverse link data inactivity above a time threshold, a message is generated and transmitted on the reverse link traffic channel at a power level sufficient for the access network to measure transmission statistics to determine whether to adjust the current transmission power level setpoint of the access terminal. Alternatively, the access terminal notifies the access network of an upcoming reverse link data inactivity period, and then lowers its transmission power level setpoint to reduce power consumption during the reverse link data inactivity period. Then, upon detection of a potential reverse link data transmission, the access terminal may then send one or more messages to prompt the access network to modify the access terminal's transmission power level setpoint. | 10-14-2010 |

20110314139 | MANAGING A CLIENT APPLICATION SESSION BASED ON A STATUS OF A LOCAL WIRELESS CONNECTION BETWEEN PRIMARY AND SECONDARY COMMUNICATION TERMINALS - In an embodiment, a secondary communication terminal (CT) executes a client application to engage in a client application session (CAS), the secondary CT configured to connect to a primary CT over a local wireless connection (LWC), the primary CT having a higher-quality user interface environment as compared to the secondary CT. The secondary CT establishes the LWC with the primary CT during the CAS and, responsive to the establishment, negotiates with the primary CT to selectively transition the CAS to the primary CT. Alternatively, the primary CT executes the client application before the establishment and negotiates with the secondary CT to selectively transition the CAS to the secondary CT. In another embodiment, the primary CT hosts the CAS while the LWC is established with the secondary CT. Then, upon disconnection of the LWC, the secondary AT selectively transitions the CAS to the secondary CT. | 12-22-2011 |
20120295617 | SELECTIVELY EXTENDING A WAITING PERIOD BEFORE AN ORIGINATING USER EQUIPMENT FAILS A CALL BASED ON NETWORK INFORMATION OF ONE OR MORE TARGET USER EQUIPMENTS - In an embodiment, network information associated with a plurality of user equipments (UEs) is determined by an application server. For example, the network information can include information indicative of whether the respective UEs are connected to fast-response networks or slow-response networks. The application server receives a request from an originating UE to initiate a communication session to at least one target UE among the plurality of UEs. The application server selectively requests the originating UE to extend a wait timer based at least in part upon the determined network information for the at least one target UE, wherein expiration of the wait timer prompts the originating UE to fail the communication session. The originating UE receives the extension request from the application server and extends the wait timer such that call failure due to wait timer expiration is delayed and/or avoided. | 11-22-2012 |
20130024473 | INTEGRATED DISPLAY AND MANAGEMENT OF DATA OBJECTS BASED ON SOCIAL, TEMPORAL AND SPATIAL PARAMETERS - An embodiment is directed to displaying information to a user of a communications device. The communications device receives a query including a social parameter, a temporal parameter and a spatial parameter relative to the user that are indicative of a desired visual representation of a set of data objects. The communications device determines degrees to which the social, temporal and spatial parameters of the query are related to each of the set of data objects in social, temporal and spatial dimensions, respectively. The communications device displaying a first visual representation of at least a portion of the set of data objects to the user based on whether the determined degrees of relation in the social dimension, temporal dimension and spatial dimension satisfy the respective parameters of the query. | 01-24-2013 |
20130072249 | METHOD AND APPARATUS FOR DELIVERING INFORMATION TO AN IDLE MOBILE STATION IN A GROUP COMMUNICATION NETWORK - Delivering information to an idle mobile station in a group communication network includes delivering the information to the mobile station in special form, e.g., short data burst (SDB) form, if the information is smaller than a predetermined size limit. In one embodiment, the information is encapsulated inside a frame, forwarding the frame to a server for delivery to the mobile station, and causing the server to extract the information from the frame and deliver the information to the mobile station on a forward common channel. Another aspect provides for receiving information for delivery to the mobile station, the information being tagged for delivery on a forward common channel, and delivering the information to the mobile station on the forward common channel. Another aspect delivers the information when the mobile station is in idle state with no traffic channel. | 03-21-2013 |
