Abstract:
Disclosed is a method in a multi-hop network node for reducing data traffic loading comprising the steps of storing (204) a first communication portion, of a plurality of communication portions, received at a network node in a network node memory. Then generating (206) a first communication portion checksum and forwarding (208) the first communication portion to a destination from the network node. The method in the network node also comprises storing (210) the first communication portion checksum in a table of the network node. Then receiving (302) a second communication portion and determining the second communication portion checksum. Then determining (304) that the first communication portion checksum and the second communication portion checksum are the same and determining (310) that at least one more communications portion of the plurality of communication portions, already stored at the network node, is associated with the received first communication portion. The method then comprises sourcing (316) from the network node the at least one more communication portion to the destination.
Abstract:
A presence attribute information server and manager application, and corresponding method is provided for managing access to presence attribute information. In addition to the presence attribute information entries, access authorization entries associated with at least some of the presence attribute information entries are provided which define conditions in which access to the presence attribute information is authorized. Generally, the defined conditions can include temporal and/or spatial requirements associated with either the user requesting the presence attribute information or the person/item associated with the presence attribute information, for purposes of establishing authorization to access the presence attribute information.
Abstract:
A wireless communications unit 200, and corresponding method within, is arranged and constructed for choosing a system selection algorithm that is used for selecting a system to provide services for the communications unit and comprises: means for associating a location with the wireless communications unit 223 215; a controller 209 for choosing a system selection algorithm from a plurality of such algorithms based on the location, where the chosen algorithm includes scan parameters (FIG. 3) that vary with the location; and a receiver 205 controllable by the controller according to the chosen algorithm to search for a system to provide service for the wireless communications unit.
Abstract:
A method and apparatus determines whether a wireless apparatus (106a) that is operative to communicate over both a wireless wide area network (104) and a wireless local area network (102), will allow shared use of its short range wireless resources, such as LAN radio frequency bandwidth, optical bandwidth or other local area wireless resources, with other proximal wireless units (106b-106n) in the wireless local area network (102). In addition, the method and apparatus generated reward data (116) to provide a reward, such as free telephone calls, account credits, price reductions, or other rewards, so that a billing system is updated when a wireless apparatus (106a-106n) has been designated as allowing shared use of its wireless resources by other proximal wireless units.
Abstract:
A method and apparatus for mitigating the impact of lost data due to cell reselection for mobile stations operating in packet data transfer mode is described. A mobile station may perform cell reselection 2 to 4 times per minute when located in an urban area, even if the mobile station remains stationary. A mobile station moving through a communications network (100) may cross over various cell and routing area boundaries. Further, a mobile station operating in push-to-talk mode may lose up to 8 seconds of data when reselecting a cell in a new routing area. A serving cell transmits an information element (301, 303, 305) in which the mobile station is informed whether cells in its neighbor list are in the same routing area as its serving cell. If the radio link to the serving cell is acceptable then the mobile station avoids reselection to cells outside its serving cell routing area.
Abstract:
A wireless mobile terminal (10) and method for utilizing digital broadcast content records (204) selected digital broadcast content as received, for example, by a digital broadcast receiver (16) and provides editing of the selected digital broadcast content based on digital rights management data to generate customized clips of information. The selected digital broadcast content is edited (206) to produce mobile terminal edited digital broadcast content that may be, for example, distributed (208) by the mobile terminal to a plurality of peer devices. A broadcast content editor (24) allows for the editing of clips of content wherein the edited clips are then stored in memory as recorded clips for distribution by the mobile terminal. In another embodiment, a network element is remotely controlled by the mobile terminal to effect editing through the mobile terminal at the network element.
Abstract:
A method of maintaining call quality in a communication system by communicating between a base site (101) and a communication unit (113) on a first channel. The communication unit (113) monitors the downlink communication signal (116) transmitted by the base site (101) and determines a characteristic of the first channel. The communication unit (113) is then handed off to a second channel having a less aggressive reuse pattern, based on the characteristic of the first channel.
Abstract:
A communication system time division multiplexes the use of spreading codes. The communication system accepts information (301, 302) from at least two users and codes each users information utilizing error correction coders (303, 306). The coded information is then time multiplexed by a multiplexer (312) into timeslots. The output of the multiplexer (312) is spread by a common spreading (Walsh) code, scrambled with a pseudo-noise sequence, and conveyed to a modulator for transmission. In this manner, information for two users may be transmitted utilizing only a single spreading (Walsh) code.
Abstract:
A method (400) for establishing a first communication link between a communications network (105) and a network node (115) in accordance with a first wireless communications protocol. The method also can include evaluating a signal parameter for a signal transmitted between a station (110) and the network node. In response to the channel quality exceeding a threshold, the station can be signaled to establish a second communication link with the network node in accordance with a second wireless communications protocol. The network node can bridge communications between the station and the communications network.
