  • Publication number: 20130073508
    Abstract: A system of managing collaborative session control when controller is lost or changes to passive-control mode in a data communication network comprising of a control-capable terminal device that can generate and send user preferences on successive controller selection and control policy, a master server device that can make control transfer decisions or take over control upon events, a normal terminal device that can process and response to master server queries on control capacity and its willingness to take over control. These apparatus are connected to each other inside one collaborative session, regardless of their subscriptions. A method of control management of the collaborative session without constant enrollment of controller comprises the steps of sending different types of preferences to master server device; making control transfer or handover decision; and interacting with affected terminals.

  • Publication number: 20120252397
    Abstract: A system of normal service resumption comprising of a UE that is currently behaving as emergency attached after receiving an limited service indication from the network, sends a behaviour change request message when the UE enters a new tracking area with a tracking area identity that is not included in the forbidden list. The network node accepts the behaviour change request when it receives a behaviour change request message from a UE that is currently behaving as emergency attached and sending the behaviour change request message from an area wherein the UE can obtain normal service. Subsequently, the said UE and network node consider the UE to be normally attached after the behaviour change request has been accepted.

  • Publication number: 20120149386
    Abstract: Provided is a radio communication apparatus capable of reducing power consumption of user equipment by improving efficiency in the use of radio resources even in a case when a network node and the user equipment hold a plurality of bearer contexts shared therebetween. The apparatus comprises an information determination unit (101), a QoS determination unit (102) and a control unit (104). The information determination unit (101) determines whether the type of information to be transmitted is signaling or data. When the above type is data, the QoS determination unit (102) determines, on the basis of the QoS for the information to be transmitted, whether or not the information to be transmitted requires real-time transmission. When the above type is signaling, the control unit (104) selects a first establishment method for establishing just a signaling connection, without establishing a radio bearer, between the apparatus and a communication counterpart thereof.

  • Patent number: 8136154
    Abstract: Hidden Markov Models (“HMMs”) are used to analyze keystroke dynamics measurements collected as a user types a predetermined string on a keyboard. A user enrolls by typing the predetermined string several times; the enrollment samples are used to train a HMM to identify the user. A candidate who claims to be the user provides a typing sample, and the HMM produces a probability to estimate the likelihood that the candidate is the user he claims to be. A computationally-efficient method for preparing HMMs to analyze certain types of processes is also described.

  • Publication number: 20100260735
    Abstract: A method for promoting the health of a plant comprises administering malic acid to the plant or the soil in an amount effective to recruit plant growth promoting rhizobacteria (PGPR) to the plant. Administration of malic acid promotes biofilm formation of PGPR on the plant's roots, thereby restricting entry of a foliar pathogen through stomatal pores present in the leaves. Another method for promoting the health of a plant comprises administering acetoin to the plant or the soil in an amount effective to increase pathogen resistance in aerial parts of the plant.

  • Patent number: RE41811
    Abstract: A single database maintained centrally hosts both proxy service data and authentication, authorization and accounting (AAA) data. Data is then copied to storage used locally by each system when both systems are instantiated. Therefore the ISP/Telco need not maintain two different data bases. A protocol gateway (PGW) is used to determine if the incoming user is a wholesale or retail user. The PGW filters the domain portion of the access request to locate a remote AAA service. If one such service is found, the PGW routes the communication via the proxy service to proxy it to the remote AAA service. The returned packet from the remote AAA service is then searched for an IP address to be assigned to the incoming user. If one is not found the PGW obtains a dynamically allocated IP address from a DHCP server (using an IP-Pool-ID if supplied in the returned packet from the remote AAA service). The same mechanism is used to forward accounting event packets from the NAS to the remote AAA server.
